Therefore, audio speakers need to undergo air tightness and waterproof testing to verify the waterproof performance. So how do audio speakers perform air tightness and waterproof testing?The following is a case of air-tightness and waterproof testing of audio speaker cavity shared by Hirays Technology.

Precision leak detection system performance parameters

The customer requested to make the audio speaker cavityIP67Waterproof level test, the following is the equipment used and testing plan:

Equipment used: Hirays dual-station classic series air tightness and waterproof testing equipment

Testing plan: direct test method, customize the mold according to the structure of the product, put the product into the mold, press the double start button on the tooling and press down on the upper mold to seal the product. The instrument inflates, stabilizes and tests the product from the upper mold.After a set time, the change in air pressure in the product cavity is detected to determine whether the product is leaking (leakage value:≤0.05KPA).Test pressure5KPA, inflation time8S, stabilization time8S, test time5S。
