Nowadays, many mobile phones have waterproof functions. In order to ensure the overall waterproof performance of mobile phones, manufacturers generally also do some modifications to the accessories of mobile phones.Waterproof testing.As a sound-producing accessory, mobile phone speakers areWaterproof testingimportant parts.The speaker diaphragm on the speaker is designed to be waterproof.The speaker and the shell are pressed and waterproof by a rubber ring.Hai RuisiMobile phone speaker waterproof testThe instrument is to detect whether the product is completely waterproof and to detect defective products through our instrument. 

The test item to be tested this time is the mobile phone speaker.According to the customer's requirements, the test pressure of the customer's product must be150KPA, because the product is very small, we set the air intake time to 3 seconds, the voltage stabilization time to 5 seconds, and the test time to 3 seconds.Because the product is relatively small and the output is relatively large, and the customer has a limited budget for air tightness testing equipment, Hirays engineers designed an air tightness detector for the customer that can test three products at the same time, which not only meets the customer's requirements but also saves costs.

As can be seen from the picture, the speaker of this mobile phone is very small, and the internal space is relatively small, which is also the difficulty of testing. If the internal space of the product is too small, during the inflation stage, a small amount of test air will fill the internal space of the product, and it will be difficult to test whether the product leaks. Hirays air tightness testing solves this problem.Hirays air tightness detector has a detection program specifically for small product leaks.

Mobile phone speaker air tightness testing process 

First, connect the instrument and tooling to the power supply and air source. Because the test medium is compressed air, the air source is necessary, and the air supply pressure needs to be atBetween 0.4-1.2MPA.

On the instrument interface, set the test parameters, air supply pressure150kpa, air intake time 3s, pressure stabilization time 5s, test time 3s. After all parameters are set, the test product can be put into the mold to start air tightness testing.
