Boiler is a measure to quickly make the equipment aging and stable. The parameters of the various capacitors inside the newly purchased headphones are unstable, and it will take a while to use them. In addition, the new earphone diaphragm folding ring has poor mechanical compliance and relatively large distortion. After a period of time, the distortion becomes normal. After the machine is burned, the diaphragm fold ring will be impacted by the pressure of sound and air, the contraction ability of the diaphragm fold ring will become more elastic, the sound detail performance is richer, the sound is excessively smoother, and the vocal voice is more mellow In addition, the high-frequency burrs will be significantly reduced or directly reach the state of no burrs, and the low-frequency will obviously converge a lot, becoming more elastic and cohesive. Reduce the back noise and improve the purity of the low frequency.
However, there are a lot of burn-in methods circulating in the earphone industry, propagating how to perform a quick burn-in method to achieve the best sound quality of the earphone. Since many earphone users still don't understand the burn-in, they will try those burn-in methods with suspicion. In fact, many of these claims are rumors, there are misunderstandings, can not achieve the effect of burn-in, and will cause damage to the headset. The following is an explanation for everyone, the three taboos about the machine burn-in.
Don't loudly
After many users get the headset, they often turn the volume of the player to the maximum at the beginning to start a high-volume burn-in. It is said that this increases the speed of the machine. It is true that the high-volume boiler can make the diaphragm of the earphone move quickly, thereby speeding up the boiler, but we know that when the earphone is shipped from the factory, the diaphragm, especially the folding ring, is relatively hard. During the burning process, the ring gradually Softening is the main reason for the improvement of sound quality, but if you use a high-volume boiler at the beginning, the folding ring will move greatly before softening, which can easily shorten the life of the folding ring, and even slightly crack or break the sound. . Just like you can’t participate in the exercise right away before a fitness exercise, you need to warm up to achieve a pull-up effect. Therefore, high volume is a big taboo when using headphones. Under normal circumstances, you must first listen to it, and burn it at about 50% of the maximum undistorted volume of the headphones, so as to ensure the effect.
Avoid long overtime
I believe that many earphone users have seen the burn-in method for how many hours or even a few days, and even said that they are wrapped in clothes and quilts to avoid noise interference. Many people have done this Convinced. There is a big risk in this approach. The earphones will generate a certain amount of heat when they are working. Long-term burn-in may cause problems such as the temperature of the voice coil, the deformation of the fixed frame of the voice coil, the melting of the glue and other problems, and the earphones are wrapped. It will also cause the heat to not be discharged. This will affect the sound quality, prone to treble degradation, and noise caused by the sassafras ring. Therefore, it is best not to burn headphones for more than three hours at a time. If you still need to cook again, you should continue after half an hour.
No heavy bass
It is the preference of many users to burn the machine with music with rich bass and special bass audio signals. They think that the bass effect of headphones will be better in the future, but the consequences of pure bass burning are serious. Because my bass signal is strong, the vibration amplitude is large, and the human ears are not sensitive to bass, even if you listen to the sound when the machine is burning, the vibration amplitude of the folding ring and the heating of the voice coil are still serious. More importantly, large vibrations for a long time may cause the voice coil to be shaken apart, which may cause problems such as dull earphone sound and low volume. Therefore, when burning headphones, it is best to avoid using strong bass music, and when using a signal generator, it is best to choose folk song noise with a wider frequency spectrum for burning.
A transmitter sends both audio and video signals over the air waves. Transmitters usually transmit more than one signal (TV channel) at a time. A transmitter modulates both picture and sound into one signal and then send this transmission over a wide range to be received by a receiver (TV set).
It is an electronic device that radiates radio waves that carry a video signal representing moving images, along with a synchronized audio channel, which is received by television receivers ('televisions' or 'TVs') belonging to a public audience, which display the image on a screen.
