However, when people use it carelessly with water, it may cause damageTWSThe headset is damaged and cannot be used, or whenTWSThe earphone body is easy to be affected by moisture in the humid air, which leads to the damage of the loudspeaker and causes economic losses to people.With the continuous updating of technology, it is necessary toTWSThe waterproof function of earphones also has higher requirements, so many manufacturers are in the marketTWSEarphones are tested for water resistance before they leave the factory.

Due to the customer's requirements for this testTWSThe earphone is operated on the whole machineIP67For the waterproof level test, Harris technology decided to use the following testing equipment and solutions:
Equipment used: HarrisHCClassic series air tightness and waterproof detector
Solution: the direct test method is adopted to test, and the mold is designed according to the structure of the headset. The mold is divided into three test parts, and each part is tested separately to ensure that all parts of the headset can meet the waterproof requirements. Insert the air pipe of the part to be tested into the instrument, put the product into the mold, press the start button, the mold blocks the test parts of the earphone, and the instrument enters the test program. First, pump the earphone, then stabilize the pressure, and finally test the pressure-17KPA, inflation time8S, voltage stabilization time8S, test time:5S, leakage value0.05KPA。
