As mobile phones play an increasingly important role in people's lives, the waterproof function of mobile phones has also become a major selling point of mobile phones.Nowadays, many smart phones have waterproof functions, such as mobile phone cameras, mobile phone speakers, and mobile phone speakers.

For the waterproof testing of the entire mobile phone or the waterproof testing of mobile phone accessories, the most economical and effective method at present is to use air tightness testing equipment (also known as waterproof testing equipment), developed by HiraysAir tightness testing equipmentIt is a non-destructive testing instrument that uses compressed air as the testing medium. It will not cause secondary damage to the test product, and the test accuracy can reach 1pa. The test data can be exported to a computer, and the quality of the product can be traced. Currently, a multi-channel air tightness testing equipment has been launched. One device can test multiple products, which greatly reduces the cost of product air tightness testing.

This time I will share with you how Hirays Technology performs waterproof testing on mobile phone speakers.The mobile phone speaker is very small, and the customer hopes to test four products at the same time.Therefore, we built this four-channel mobile phone speaker waterproof testing equipment for the customer. According to the shape of the mobile phone speaker, four profiling slots for placing the mobile phone speaker were made on the test fixture.Each square groove is connected to an air inlet pipe, and the sealing of each mobile phone speaker will be judged individually on our air tightness testing equipment.

The testing process of the Hirays air tightness detector is divided into three steps, namely the air intake stage - the voltage stabilization stage - the testing stage.The waterproof level standard of mobile phone speakers for this test is IP68. According to the product test standards, we set the test parameters for the product as test time 10s, voltage stabilization time 10s, test time 10s. The test pressure is 18kpa, and the upper limit of leakage is 0.04kpa.The test parameters are set after many tests based on product characteristics and customer requirements. The test parameters of different products are different and cannot be directly applied.
