Necessity of using mobile phone headphones
We may all have this experience. When we talk on a cell phone, if we spend too much time, we will find that the brain that answers the phone will be very uncomfortable. This may be the result of the long-term radiation of the cell phone. So when pregnant women do physical examination, doctors will emphasize that as little as possible or do not use mobile phones, to avoid harmful radiation affecting the fetus.
Although every mobile phone will be equipped with headphones, but consumers really use headphones very little, the main reason is inconvenience.
Science and technology can not only promote the progress of human material civilization, but also damage human body, so science and technology is a double-edged sword. While enjoying material civilization, we should also be aware of the side effects of civilization. When the government's supervision is weak, we need to protect ourselves by ourselves. Mobile phone radiation is absolutely a problem that everyone who uses mobile phones must clearly understand. For their own health, it is recommended to use mobile phone headphones to talk.
The mobile phone headphones sold on the market are synchronized with the main products. The headphones of high-end brands have fine workmanship, good sound quality and stable performance. The low-end mobile phone headphones are rough and sound-free, but there should be no problem in talking, but listening to music is absolutely a kind of damage to the ears.
The competition in the headphone market is very fierce. In order to reduce the cost and control the purchase price of headphones, mobile phone manufacturers know that there are few consumers who really use headphones, so there are not many really good headphones. Unless some cost-effective mobile phones, they must equip a top-grade headphone.
As far as the difficulty of production is concerned, mobile phone headphones are the most difficult to produce in civil headphones, which are shown as follows:
1. Complex structure. In a small space, repeated wiring and routing will accidentally overlap each other, resulting in short circuit.
2. The space is narrow. Mobile phone headphones are small and light, so the components are very small, but also to achieve a lot of functions, so the welding process is demanding, workers produce as if in rust.
3. Difficult assembly. When assembling the finished product, no half-point deviation is allowed, otherwise it will affect the mismatch of the shell and the failure of the keys.
4. The test is complex. In the production process of mobile phone headphones, because of artificial or non-artificial factors, the product failure rate is high, so it must be tested in stages. For example, wire testing, receiver testing, receiver testing, keystroke testing and so on.
5. Highly demanding. This is for high-end mobile phone headphones.
6. Mobile phone headphones need to be able to withstand falling, so the structure should be very firm.
7. Torsion and tension, which reflect the level of manufacturers. Really good mobile phone headphones can withstand repeated torsion and high tension. Some low-end headphones will disintegrate if they exert a little force.
8. Sound quality effect is good. A good mobile phone headset, whether listening to music or talking, has good music resolution, clear voice and not harsh.
