Apple has launched itsAfter Airpods headphones, many headphone manufacturers have launched their own brands of true wireless Bluetooth headphones.Because Bluetooth headsets are relatively small, they need a storage box.At the same time, the headset body is small and the battery life is relatively short. When not in use, the headset can be placed in the charging compartment to charge.The headphone charging compartment serves two functions: storage and charging.With the popularity of waterproof sports headphones, the waterproof testing of headphone charging compartments has also begun to attract attention from major manufacturers.

As an electronic product, the earphone charging case’s sealing and waterproofness are closely related to the quality of the product.Especially earphones used outdoors will be regularly exposed to sweat and rain. The sealing and waterproofness of the battery compartment are related to the service life and quality of the earphones.Therefore, it is necessary to conduct a waterproof sealing test on the earphone battery compartment before leaving the factory.This time the customer wants to make a battery compartment for this headsetWaterproof testing equipment。

Customer testing requirements are as follows:

1. Waterproof level:IP67 waterproof etc. 

2. Detection efficiency:200 pieces/hour

According to customer requirements, Hiraysi Technology has made the following testing solutions for customers:

1. Test pressure: 13KPA (simulating the test pressure of the product when the water depth is 1 meter)

2. Allowable leakage: 0.1kpa (equivalent to 100pa)

3. Test data: air intake time is 3S, voltage stabilization time is 5S, test time is 5S, plus loading and unloading time, the time to test a product should be 18S. Exactly 200 products can be tested per hour, which can meet the needs of customer factories.

Test process:

1. The operator places the headphone battery compartment onto a mold specially made for the battery compartment.

2. After placing the product, activate the start button on the fixture with both hands, and the upper mold will be pressed down and sealed under the action of pneumatic force.

3. After the mold sealing is completed, it will enter the testing stage and the system will automatically enter the air-Voltage stabilization-test three stages

4. After the test is completed, the tester will automatically determine whether the headphone battery compartment isOK or NG.

This time we used the classic model of Hirays.HC air tightness testing equipment comes with positive and negative pressure testing, and the testing accuracy can reach 1pa. This air tightness testing instrument is not only suitable for earphone battery compartments, but also suitable for Bluetooth headsets, face washers, electric toothbrushes, electric shavers, and other types of electronic products that require waterproofing.
