Overview

Today’s handheld electronic devices (such as cell phones, wearables, Earphones, smart watches, Bluetooth speakers, smart speakers, walkie-talkies ), these portable products are often used in some harsh environments, such as rainy days, swimming pools, underwater sports, skiing, mountain climbing, running, etc. environment of.

Using these portable products in such harsh environments, The structural challenges faced by the microphone (acoustic receiving part) and speaker (sound emitting part) are:Splash of dust, pollutants and particles, sweat erosion, fresh water and sea water Immersion.

These challenges often result in water damage to the microphone or speaker, Blockage, increasing number and weight will prevent speakers from producing high sound pressure levels and degrade acoustic quality. Although the IP6X protection level can effectively protect against particulate matter, it does not protect against haze, smoke, tobacco smoke, and dust with a size smaller than 10 μm, especially between 1-10 μm (a common particle size range in mobile electronic device application environments). particles, making it difficult to effectively protect.

For smart wearable devices for underwater sports, often It is required to be waterproof to 3ATM (30 meters waterproof), 5ATM (50 meters waterproof) Even 10ATM (100 meters waterproof). In order to ensure that smartphones and smart wearable devices are both waterproof and breathable at the air outlet, while maintaining the clear sound quality of the microphone, this places higher requirements on the protection level and waterproof performance of the speakers and microphones.
