Repair or throw Edit Weapon headphones bad how should I do
The headset is essential in our lives a listen to the vast majority of young people will use headphones to go out listening to music. Although not everyone will be to buy the headphones, but everyone has their own earplugs monster beats pro, because even buy a mobile phone is also bundled. However, people tend to be more like music are not satisfied with bundled plug, but a better some headphones for music listening.
Although the headset is the electronic products, but it is not like other electronic products as life expectancy was short, generally as long as we do not have the impact of external forces will not cause its damage. We all know that long, with the time to listen to headphones, the inside of the diaphragm unit after aging will make the sound more mature, so the headset is generally not a new best, but the more you use, the better the sound of the open burning of headphones listening more comfortable.
Many of my friends have a headset can be used for many years, but as the articles, after all, aging damage, bad how should I do? This thing, unlike other electronic products as easy disassembly, it is also very troublesome to repair, and it is not purely electronic principles, completing the sound will change? Here, we work together to chat headset is broken how should I do.
Generally not be purchased separately headphones friends, bundled headphones if bad may be directly thrown away, and I think many people are doing so. Indeed as the phone comes with headphones in general will not give separate warranty, if broken can only throw away, because our own is difficult to be able to fix it.
But there are also many strong hands of friends will take into account their own apart to repair them, but before you do, because sometimes the problem may not be the headset. If your headset does not ring, first check your own audio and connectivity issues, perhaps the problems are not out on the headset.
But the headphones if the sound is a problem, check the plug connection stability is very necessary, because the headset is not stable when plugged into the jack, the sound will indeed be a problem. Checked the plug properly connected, the sound and then have a problem, there may be problems of their own headphones.
We can in turn touch the wires, plugs and units where there is a problem, and then to see whether they can repair, be sure to do what not, then it is recommended to find a professional maintenance staff to solve.
But for the friends who have paid to buy a headset, the bad do not need to throw away, headphones and cell phones, our first thought would be warranty issues. So here we still have to remind you to buy headset must look for the regular stores to ensure product quality and after-sales service. The headset is only regular store to buy has a warranty, purchased in other places may also purchase "parallel imports" - and the phone is a reason.
Genuine licensed headset general warranty card and accessories are more complete, serial numbers and anti-counterfeit labels, information is also in full display for everyone, and the packaging of most headphones have a security coating, as well as the security phone, it is convenient to be able to query the authenticity of headphones you buy.
Buy headphones, of course, we must pay attention to fill out the warranty card, the real information to fill in the above, and the need to affix on the chapter of the dealer. We need to save up their purchase receipt, warranty card and box, because a lot of products, service need to provide these things. Therefore, only this headset warranty eligibility.
Closer to home, if your headset is a problem, if it is genuine headphones store to buy, then the need to provide the warranty was purchased box of receipts and headphones. Headphones on the date of purchase, so the receipt is still necessary; has a headset on the box serial number and other information to be able to find your headset is where to buy.
Well-known brands like Sennheiser, AKG headphones provide two years of replacement service, that our headphones if there are problems, there is no warranty period, are holding what they need can go directly to the store to change new uses. Of course, you can also go to the major brands of after-sales service centers to be replaced, not purchased in the past the store to replace it seems more convenient.
Of course, if the warranty period, we are required to pay their own maintenance, but stores generally do not charge too expensive maintenance costs, a lot of things still have a clear price standards. We learned from Sennheiser stores, general headset repair the plug, then a small headset is $ 20, while the headset is $ 30, high-end headphones 6.5mm plug maintenance costs compared to 50 yuan.
Like wire and ear accessories, and other aspects of replacement is not expensive, PX100-II like headphones-for-line only about 30 yuan, an earmuff only 30-40 yuan. The headset of different grades of material difference between the cost of maintenance is not the same, we need to consider whether it is worth the repair, maintenance costs are too expensive, then better to buy a more cost-effective.
If the headset is not in regular mainstream stores to buy, you may need to find the headphones be able to repair the maintenance point of repair, because the headset does not carry a warranty, so the problem was responsible for their own. Like the magic sound of this headset in the country and there is no specific stores, and sales of headphones is not necessarily come from the formal channels, warranty up is not a small problem.
However, the maintenance point of the headset is not as formal as headset brand aftermarket center charges a uniform standard, a lot of maintenance repair will be "Man" money people do not understand more than Mongolia, for the knowledgeable less black, we must to prevent the experience of black service points.
If you really need to get the private repair point to repair, it is best able to go professional after-sales repair centers repair, if you must repair the maintenance point, be sure to ask a few, I have one end of the easier and maintenance points to bargain, so as not to make money, and eat the unnecessary loss.
While these things is not anything special "smart" tricks, but for some people, they do not pay attention to these issues, for example, some people outside the dealer to buy in order to map a few dozen dollars cheaper, but when headphones problems when in trouble. Therefore, we recommend the purchase of authentic licensed, ask about after-sales service, and to rationally deal with problems in the headphones, do not immediately throw directly. Maybe the warranty can "save" your headphones, bad new ones directly to you not better?
1831 Faraday found that when the magnet passes through a closed circuit current will produce. The great discoveries of mankind to create the world's first to produce a continuous current generator. With continuous supply of electrical energy, from human to enter the era of electrical applications, the electrical interface is also the influx of people's lives in various forms. To a few hundred years, today, around us all the electrical equipment, was surrounded by at least one interface, their function, or a single or comprehensive, but one thing is certain, that we can not do without them. because at least our devices need to connect the power.
What is the interface? The Tablet PC interface is defined, it can connect two or more than two different circuit devices, to enable them to pass the electronic or any form of signal devices. Then we can use the Tablet PC interface to do? With the development of the Tablet PC, its function is not limited to charging, listening to music and the progressive realization of high-definition audio and video output, the expansion of the external devices, it has more operating experience.
From this we can in accordance with the purpose interface is divided into two categories, to supplement the class interface and expand the class interface. Supplement the class interface to provide added support on the basis of the existing features of the Tablet PC is the vast majority of the standard configuration of the Tablet PC. The typical interface for the power connector, Micro SD card slot, headphone jack. Expand the class interface to an external entity such as keyboard, TV panel itself, the function can not be completed, the typical interface for OTG interface, HDMI interface, a dedicated data interface with the SIM card interface, they are not necessarily in all plates are equipped with, but they existence can provide users with more useful features, better user experience. Below please follow the author of fine chemicals these interfaces 1000 AIDS Subway.
The Tablet PC you want the normal use of supplementary class interface is essential. Power interface for the Tablet PC to provide adequate power capacity Micro SD card slot can provide additional savings, the headphone jack to allow people to exclusive beautiful melodies in a noisy environment, but perhaps many readers will ask, these interfaces in already been made, on my cell phone and MP3 plug in will be able to use, good introduction? In fact, a great deal of inside knowledge, if we are not the proper use will damage equipment, causing unnecessary losses, these events exist in the real friend of the author around the body. Note so I will focus on providing for the use of readers for each interface.
Operation and function: charger into a socket, the cable into the machine power connector for the built-in lithium rechargeable.
Interface Type: Tablet PC charging port can be the specificity of single-use interface from the data line interface for charging, but bearing in mind that not all of the data line interface can charge for the flat panel.
First: that the charger as long as the interface corresponding to be able to use. The charger output specification is marked on the charger nameplate output voltage, current (such as 5V2A, 9V1A, etc.). The machines have a rated input voltage and current, voltage determines the battery can not be filled with the current value will affect the charging time. Different flat-panel charger appearance and wire similar to the output specifications are not the same, if the access error, ranging from battery life, re-burn machine.
Second: to buy a new battery need to charge 12 hours in order to function properly. Lithium batteries differs from nickel-cadmium batteries (Ni-Cd), it does not have a memory effect, and full of need to disconnect the power as soon as possible, otherwise it will reduce battery life.
: Fear of charging too many times to affect battery life. The lithium battery life is reduced with increasing use of time is not determined by the frequency of recharging lithium battery can be used with the charge, but try to charge when the battery is more than 20% once a month End safe charging and discharging process, which helps to maintain battery life.
Operation and function: the Micro SD card correctly specify the location of the access plate, you can enhance the storage capacity of the flat.
Interface Type: Micro SD card slot interface is too large, deep gaps, so a lot of flat-panel manufacturers this interface design is hidden, to prevent dust from entering the lead to poor contact, and increased body beauty. Of course there are many manufacturers directly exposed, easily accessible
Editorial: Micro SD card, also known as the TF card has a variety of capacities. Recommend users to buy the 32GB following capacity, high cost, while the poor compatibility of the equipment of the savings of the 64GB capacity card, so do not recommend buying. Another point to note is that the Micro SD card petite easily broken, so the plug when the force is not too large.
Operation and function: the headphones plug into the interface will be able to allow headphones loud, headphones and equipment to support the wire, we can also control the machine to play, pause music, 3G tablet can also use it to call hang up.
Interface Type: headphone jack 2.5mm, 3.5mm and 6.5mm 3 different caliber, appearance, structure exactly the same (provided that the wireless control function). Small-bore connectors can be inserted through the adapter interface normal large-caliber work. I see all the Tablet PC with 3.5mm interface.
Believe that readers no stranger to the headphone plug on the map, we were young player with this 3.5mm plug. To pass through the different areas of the division of signal 1 ground, 2 headphone right channel, 3 headphone left channel, four insulated wire between the different conductors. From the figure might be able to see that the bottom of the headset to mono, an insulated wire, the upper two-channel stereo, two insulated wire, like the iPhone headphones have four insulated lines represent the mean ? 3 channel? Wrong, it usually indicates that this is a paragraph-by-wire headset, if your tablet has a support wire headset interface, then plug in the specific headphone wire can be achieved.
A vivid metaphor, to expand the class interface is like a plug for flat wings allow it to fly, to achieve the function itself does not have alone. Readers to buy the Tablet PC to take into account whether they will use these functions, must also increase the manufacturing cost of the Tablet PC to enhance the added value of the tablet. Here let us to learn more about the next of these interfaces.
Operations and functions: HDMI interface for its transmission speed up to 5Gbps, and supports audio and video output at the same time becoming very popular among the mainstream image transfer interface. Its use is also extremely convenient to connect an external monitor or TV Plug and Play.
Interface Type: HDMI interface in accordance with the physical specifications can be divided into A, B, C, and the D4 categories, including Class A interface 19-pin shape is similar to the letter D, is widely used in TVs, monitors and other video equipment, is the highest penetration rate in the category . Class C interface and Class A of the same structure, but the volume is only 1/3, Gu used for tablet PCs, mobile phones and other portable devices, we can switch wiring Class C interface to convert Class A connectors, which tablet high-definition audio and video information in the computer is put to the display device.
Editorial: The HDMI interface is not essential Tablet PC interface, with its Tablet PC operation screen image on the display devoted to the display device, we can use this function to share high-definition large, or by access through television and family into the projector and colleagues to share information on the tablet.
Operation and function: OTG technology developed in recent years, it is used for the transfer of data between different devices, and interpretation of the advantages of a unified interface and multi-purpose. Specifically, the tablet OTG interface can be linked, such as mouse, keyboard, handle a variety of external devices, thus facilitating the operation and the text entry; access U disk facilitate the sharing of files; external 3G module enables devices anytime, anywhere the Internet; an external GPS module for user navigation, turns out to be the interface of the Almighty.
Interface Type: OTG USB-based interface developed technology, so it is fully compatible with USB 2.0. Interface morphology is that several forms of USB, is divided into ordinary USB jack, Micro USB interface with mini USB interface. The latter two interfaces can be converted into common USB interface adapter cable.
Editorial: and then all-powerful interface only use it in order to reflect the value, how to use the editing in particular, to introduce to you. If you usually at home reading or watching the video, take a long time holding the device, we can flat-panel fixed to a location, use the mouse to operate the tablet connected OTG, following the simple without effort; the same in the chat use the keyboard for text entry is certainly higher than the touch screen efficiency.
Operation and function: a dedicated data interface manufacturers specifically for the Tablet PC design, data transfer interface, general functionality of such interfaces stronger, in addition to device charging and data transmission can also be directly connected to external devices or by transfer separation of wiring, such as HDMI, SD card, USB interface.
Interface types: the large flat-panel manufacturers, dedicated data interface types varied. Dedicated transfer interface was undoubtedly the Apple 30-pin iPod DOCK interface, it is almost on the Apple portable devices.
Editorial: special data interface to meet the characteristics of the interface over one, but each vendor's interface does not have a unified specification to ensure that universal care will not be gaining in popularity, will be late for the user due to external damage to the equipment, but nowhere buy corresponding Accessories lay hidden. Of course, like Apple, Samsung, so penetration is very high global equipment manufacturers do not consider this issue.
Operation and function: Since you readers used the phone, then install the SIM card will be not a problem. But unlike the phone, some Tablet PC after installing the SIM card and can not receive calls, such as Apple's iPad, because they are designed in order to provide the ability to flat panel anytime. Fortunately most of the Android 3G tablet support phone text messaging function.
Interface Type: iPad 3G version of the Micro SIM card, it is actually just an ordinary SIM card truncated part of it, and then inserted into a dedicated SIM card slot, SIM card interface can be divided into a large mouth and small mouth.
Tablet, after all, is not used to call, so the choice of 3G data plans for the tablet, to consider the amount of specific tablet, laptop and other equipment to China Unicom 3G package price of $ 80 1G. The 3G network is the point of the consumer confused, at present China has three kinds of network standard is divided into Unicom's WCDMA Telecom's CDMA2000 mobile TD-CDMA, the most flat-panel only support China Unicom's 3G standard.
After nearly two and a half years of development, flat interface also with the changes in the industry towards the more conducive to the use of more powerful direction of change.
In the iPad in 2010, first release has a huge market share, almost to a monopoly-based tablet interface is Apple's single dedicated data interface, people are forced to buy expensive adapter cable to complete the expansion of functions, such as one-HDMI cable prices will more than four hundred dollars. We can not deny that the interface is less and not necessarily expand the weak, but we also found that we have added a financial burden and inconvenience like this need all kinds of expansion line interface virtually. So can a simple interface to expand the task has become a strong voice in the market.
With the release of Android4.0 system, Android flat development to enhance the quality, now most of the Android tablet support functions such as HDMI, USB, the host, Micro SD card to expand, where HDMI is a standard measurement equipment video output capability . It is precisely because such a high degree of development makes Android devices have the charm system share was beyond Apple the top spot among the market. Expensive adapter cable is no necessary, one can directly connect peripherals to operate the tablet. Advantage accentuates has extensive expansion of the interface.
Win 8 tablet is further blurring the gap between tablet and computer products, it has compared to today's Tablet PC for better performance and better expandability. With the flagship of Microsoft, Win tablet will become the marketplace of the future of the Tablet. This also allows us to look forward to a new round of changes it can lead to the interface, USB interface as standard Win 8 tablet is a prominent feature, we were delighted to find that through which we can access most of the computer peripherals, including printers, key mouse, U disk.
The mobile phone has become an integral part of our lives digital products to the smart phone by the function machine, function more and more powerful, but its power is gradually increased. Recently, scientists found that when we too often use the phone to answer the phone, your saliva will become no better than commonly used mobile phones. The phone is beginning to affect some people's saliva secretion system.
In fact, in 1902, the Americans in the Kentucky countryside residence, Nathan Stubblefield made the world's first wireless telephone device must not think he became a pioneer of an epoch-making product, but this technology to civilian use has been pushed to 1973 by Martin Cooper invented the first commercial mobile phone, he was an Engineering Technician of the well-known communications equipment providers in the United States - Motorola, but also from his mobile phone technology gradually developed gradually into the mass consumption perspective.
Mobile development to the pattern of the world's mobile phone has also undergone tremendous changes, Motorola mobile phone system provider Google Inc. acquisition, who have dominated the world of Nokia Corporation has also been shaky, to the rich and famous fashion and multimedia features Sony parted ways. The only Sony is still struggling to support. Today's mobile phones have entered the era of smart, Apple introduced the iPhone is completely the phone's form and function to subvert, to create a new channel of a phone, which also opened the Warring States era of the mobile phone industry, in addition to Apple the iPhone, all mobile phone operators are not sub-par.
In such an era, the electromagnetic radiation produced by mobile phones on the human body is also more to be valued by four phone popcorn cooked "video some time ago crazy to pass so that we feel the horrors of the electromagnetic radiation was later shown that this is a fake news, but today we want to talk about this news is true, we have the following look.
A new study conducted by Pascal Mandy and Dental University and Research Center in India found that frequent use of mobile phones to call people secrete more saliva than the people do not often use the phone. This experiment is now being analyzed to produce this result, they believe may be the changes of the parotid.
Human parotid gland is located in the lower jaw, is the main organ of the secretion of saliva. Researchers to 142 subjects divided into frequent use of mobile phones by group and the group of general use mobile phones, and ultrasonic technology to observe the parotid gland of the two groups of people, and to record changes in the parotid gland. The results showed that frequent use of mobile phone users have a relatively large rate of the parotid gland activity and blood flow rate (high blood pressure), and they hold the phone side of the parotid gland 26% higher than the common use of mobile phones parotid saliva secretion rate. Although this result is enough shocking, but the researchers said their study did not complete, because this result only shows the saliva secretion and the frequency is related to the use of mobile phones, but there is no direct electromagnetic radiation of mobile phones will people the parotid gland growth and affect the secretion of saliva, so the research team is preparing the next survey to prove this conjecture.
Perhaps reading the above information you still feel that does not matter, nothing more than the saliva more than just a little, but the impact of mobile phone electromagnetic radiation can be more than that. Researchers at the University of Lund, Sweden After tests found that the albumin in the blood of mice lived in the electromagnetic radiation environment it is easy to break the protection of the brain into the brain, the albumin great harm to the brain. Although scientists do not know whether the electromagnetic radiation on the human brain can also cause the same consequences, but it is certain that the human brain on the protection of mice of the harmful ingredients in the blood is the same, but since the albumin to break through the protective layer and into the the brain, it can be imagined, more small virus it has been possible to enter the brain. Such a result is not to make you begin to feel fear, so cell phones has brought us a lot of the convenience, but no technology can shield electromagnetic radiation must try to avoid the frequent use of mobile phones.
To explore, to guide the consumption of energy-efficient products, to promote the upgrading of industrial structure of flat-panel TVs, July 19, the China Video Industry Association, Ovid consultation jointly organized by the second quarter of 2012, China's electronic information industry economic operation & TV industry research released will be held in Beijing, the conference officially released "flat-panel TVs Energy White Paper (referred to as the" Energy White Paper "), and prominent energy contribution to be a grand recognition.
