along withThe gradual disappearance of the 3.5mm headphone jack and people’s pursuit of free and fashionable wireless headphones, true wireless headphonesIt has become the most popular product in the headphone market now.For true wireless headphones, consumers not only care about the sound quality of the headphones, but also the waterproof performance of the headphones. Although the waterproof problem does not directly affect the experience, it does affect the usage time of the headphones.Generally speaking, the higher the waterproof level, the better the waterproof effect and the longer the life of the earphones.

There are generally two methods for waterproof testing of products. The first is to judge the waterproof performance of the product by immersing it in water and observing whether the product produces bubbles.The second is to use compressed air to determine the sealing of the product by detecting changes in the compressed air.For electronic products such as Bluetooth headsets, once water enters the product, the speakers and sound-generating components inside the headset will be damaged, directly causing secondary damage to the product and increasing the difficulty of repairing the product.Now headphone manufacturers generally useAir tightness testing equipmentTest the waterproof performance of Bluetooth headsets. 

The characteristics and test parameters of the air tightness testing equipment for the true wireless Bluetooth headset made by Hairuis Technology for customers are as follows: 

1. Usually, the headphones are a pair, so this Bluetooth headset waterproof tester made for customers can test the left and right headphones.Make two similar molds according to the shape of the earphones, and test the sealing performance of the earphones through the molds.This air tightness tester is set up to test each earphone individually, and two test programs are set up to test each earphone in turn.

Hairis air tightness detector has100 groups of subroutines, each group of subroutines can be programmed individually, single selected, and combined to meet various complex testing requirements.

2. The waterproof requirements for Bluetooth headsets areIP67 level. According to the IP67 level requirements, the test pressure set for the product is 11kpa, the air intake line is 10.8kpa, and the leakage line is 0.03kpa. Because the product being tested is very small, the set parameters must be very strict to detect unqualified products.The air intake time is 3 seconds, the voltage stabilization time is 3 seconds, and the test time is 3 seconds. Because the headphones are very small, the entire test process is also very fast.The air tightness test of a pair of headphones takes less than 10 seconds to complete.

After setting the test parameters, you can connect the air tightness detector and the test tool through the air source.Place the Bluetooth headset in the test mold for testing.

Hairis air tightness testing equipment is divided into five series, respectively: HC classic air tightness tester, HP pioneer series air tightness tester, HN pilot series air tightness testing equipment, HL leader series air tightness tester, all test the sealing and waterproofness of products.According to different customer requirements, different air tightness detectors are recommended.
