Silicone Rubber Products in Audio Component
One of the main applications of silicone rubber products in the audio and video industry is earphones and silicone earplugs. Apple's AirPods, Bose's Quiet Control, and so on.
The material classification has the following kinds:
Silicone Ear Plug
Silicone ear plug: silicone ear plug will cause pain in the ear canal and cannot be continuously and effectively muted, but the use cost is low and suitable for low-cost earphones. Although silicone ear plug is airtight and non-porous, because of its rubber hardness after rebound, it cannot completely fit with different types of adult ear canal, so it will cause air leakage. Once there is air leakage, the sound insulation effect will be reduced, which can reduce the noise about 20 or 30 decibels. The inner wall of the human ear canal is curved and soft. If blocked, there will be swelling and air leakage in the ear canal, which cannot effectively achieve long-term comfort and quiet effect and cannot be used for a long time.
Silicone Form Buds
Silicone form buds: noise-proof earplug made of low pressure foam and high elastic polyester. Smooth surface, slow rebound, no pain when using the ear, sound insulation effect between 25DB-40dB. This kind of earplug is suitable for high-end earphones, but it cannot be used repeatedly because the slow rebound effect will gradually weaken. However, with the development of science, there are also some sponge earplugs on the market that can be used repeatedly for more than half a year and can be scrubbed. Also can produce replaceable earplugs.
Silicone Ear Hook
Hook shape ear tips, that is slip-resistant and flaky, more comfortable on the ear without squeezing the ear canal, and is used in Bose's signature product Quiet Control.
