There are two points to note during the cooking process: First, do not work continuously for too long! Because the voice coil has resistance, it will generate heat after working for a long time, and it may even burn the voice coil! It’s best to stop for a few minutes every two hours and then continue. Second, the volume must not be too loud. The earplug diaphragm is a very fragile material. If the volume is high, the movement of the voice coil will be large, which will pull the diaphragm violently, causing the voice coil to loosen and the diaphragm to deform or even tear. etc. Especially for "fragile" earplugs like the 888, you need to be careful. When adjusting it correctly, just adjust it so that you can clearly hear the sound waves or the vibration of the air. Never adjust it too high and you will hear the diaphragm vibrating violently.
