Headset manufacturers: good headphones and the difference between ordinary headphones
Headphones manufacturers: To know the difference between good headphones and the usual headphones, we must first understand the principle of sound: the electrical signal comes in, through the coil to convert energy into kinetic energy, vibration diaphragm vibration. The principle is relatively simple, so cheap headphones may be less than ten dollars will be able to buy, but the sound is not the same as the headset and big.
Headset manufacturers because of the front of the signal, jack, wire, etc., will have an impact on the signal, in order to reduce the attenuation of the signal, a random headset head is almost gold-plated. Other, in order to very good equipment to weaken the noise, the greater the better the internal resistance of the headset, but the resistance is too large, and usually MP3 and does not move, so how to set the internal resistance of the headset, what impact, Equipment, these should also be carefully studied. Headset manufacturers headphones and headphones usually sounds very different, and any difference depends on a lot of manpower and material resources to achieve.
1. Earphone speaker diaphragm material is not the same, it will cause the same frequency of the sound volume is not the same, the degree of fine will be different, for example: low sound volume lack of ah, okay.
2. headphones all the shape of the cavity is not the same, will cause the sound waves through the reflection after the occurrence of different changes. Detailed selection of what shape will need to listen to, to adjust.
Whispering lack of doubt, but also thinking whispered will not be too big and the sound, treble volume will not be too big or too small, how the IF and so on. Although these headphones manufacturers can be measured out, but the details of the effect is still rely on experienced people to listen to, to adjust, after the decision to mass production.
