Boiling headphones is mainly a rapid aging process of the mechanical system of headphones. The sound system of the mobile earphone is driven by the voice coil, and the diaphragm is fixed on the shelf of the earphone. Theoretically, the diaphragm movement should be the piston (vertical) movement, which requires the diaphragm edge to have greater flexibility. Cooking here, the edge of the new earphone diaphragm is tight, with great elasticity and low compliance. Boiling an earphone is to make its edge move so that the sound can't be heard. \x0d\ The only universally applicable way to compliment headphones is "step by step". At first, let the headphones play slowly at a low volume 10-30 hours, and then use ordinary music (except rock and dance) at a medium volume 100-200 hours. \x0d\ In the process of praise, we should pay attention to the following two points: \x0d\ First, we should not work continuously for too long, because the voice coil has resistance, and it will heat up after working for a long time, which will easily burn the voice coil. It's best to stop for a few minutes every two hours and then continue. \x0d\ Secondly, the volume should not be too high. The vibrating membrane of earplug is a very fragile material. If the volume is high, the stroke of the voice coil will be large, resulting in the voice coil loosening, deformation and even tearing. \x0d\ Potting headphones is because the previous headphones are not so advanced in workmanship, and users need to re-debug the machine to make the sound of headphones have a gradual sound production process. This is an ancient traditional method. However, the headphones on the market now can achieve the desired effect without the need for users to boil the machine again. As long as you listen to songs in the usual way, the sound quality will be good. \x0d\ If you buy a good pair of high-end music headphones, you must boil it to make yourself feel better, and then you can operate the machine according to the above methods.
