Headphones are a very common electronic digital product in our lives, and they also bring us great convenience. The most commonly used function of migrant workers is the call function of the earphone. After the sound signal is collected from the earphone microphone hole, also called the MIC hole, it is converted into an electrical signal. MIC is a word abbreviated from Microphone, which is we often call microphone.
When we use earphones, most of them are outdoors or in non dry environments, so the air leak treatment of earphone holes are very important. If it is not handled well, it will affect the user's experience.
Air leak test process
Today we share the air leakage test case of the earphone microphone hole.
Test equipment:HC Classic series air leak tester machine
Testing method: Adopt the direct testing method, with customized mold and tooling. Inflate 10Kpa, 5S time, 5S pressure, 5S test.
In this process, if the program alarm or an NG signal appears, it means that the leakage exceeds the upper limit of 15kpa, and the tested product is a defective product.
