Headphones are a very common electronic digital product in our lives, and they also bring us great convenience.

The most commonly used function for workers is the call function of the headset. The sound signal is collected from the headphone microphone hole, also called the MIC hole, and converted into electrical signals. MIC is the abbreviation of Microphone, which is what we often call the microphone.

Most of the time we use headphones outdoors or in non-dry environments, the air-tightness of the headphone jack is very important. Failure to do so will affect the user's experience.

Today we are sharing aboutAir tightness test of headphone microphone holecase.

Testing equipment: HC classic seriesAir tightness detector

Detection method: Direct detection method is used, with customized molds and tooling.Inflate 10Kpa, time 5s, stabilize pressure 5s, test 5s.

During this process, if the program alarms or an NG signal appears, it means that the leakage exceeds the upper limit of 50pa, and the tested product is a defective product.
