As a playback device that transmits sound, Bluetooth headsets allow users to feel the beauty of music during use. Bluetooth headsets that have passed the sealing test can protect the life of the Bluetooth headset and increase the user's experience.As a qualified Bluetooth headset, it must pass the sealing test, but the traditional sealing test method is no longer suitable for the sealing test of many types of Bluetooth headsets.

As a developer and manufacturer of sealing testing equipment, Hirays Technology has developed sealing testers suitable for testing a variety of products.This time we will analyze the sealing test of Bluetooth headsets. We hope it can be helpful to you.
1. Analysis of Difficulties in Sealing Detection of Bluetooth Headsets
1. The shape of the earphones is relatively small, and the overall precision is high. The internal components are integrated with the outer casing. In order to allow the sound to be transmitted better, there are special sound holes;

2. The special structure of the earphone makes it difficult to detect its sealing. During the early design and production process, its shell will undergo special treatment. There is a waterproof and breathable hole on the top of the Bluetooth earphone, which can be directly inflated inside during testing;
2. Demonstration of the sealing testing process of Bluetooth headsets
1. This time, multiple Bluetooth headsets need to be tested at the same time, so we need to customize a special mold for the Bluetooth headsets. There are two grooves on the top of the mold that can be placed for Bluetooth headsets. There are two tools above that are specially used to fix the vents of the headphones. During the test, the air outlet of the Bluetooth headset fits the upper tool, and gas can be directly injected into the Bluetooth headset;

2. Before starting the test, we set the required parameters on the instrument. For this test, we need to use an air pressure value of 10.5KPA to test whether the waterproof level of the Bluetooth headset reaches IP67;
3. After placing the Bluetooth headset, press the start button. The upper appliance is connected to the instrument through a conduit. The conduit fills the interior of the headset with gas through the appliance. When the gas reaches 10.5KPA, the supply will be automatically cut off. The instrument will judge whether the Bluetooth headset meets the waterproof standard through internal air pressure changes;

4. If the Bluetooth headset is not sealed and air leakage occurs, the leakage value displayed in the instrument will become larger and larger, and the pressure value will decrease at the same time.At this time, it can be determined whether the Bluetooth headset is leaking, and the instrument test result will also show NG, which means the sealing test failed.If the tested Bluetooth headset does not leak, the gas in the tooling mold will be in a constant state after inflation. The pressure value and leakage value displayed on the instrument are also stable. The instrument test result will display OK, indicating that the sealing test has passed.
