Recently, Hairis Technology successfully completed the production and delivery of the audio air tightness detector project with Logitech.This time, Logitech ordered multiple audio air tightness testers from Hairis Technology. The equipment delivery process and project report are as follows.
one,Audio air tightness detection solution
In the early stage, the Hairis Technology special team had an in-depth understanding of Logitech's audio air tightness testing needs and developed a Logitech Bluetooth audio air tightness tester solution.The customer requires that the audio air tightness detector must meet the IPX7 waterproof level test.;The test pressure is10Kpa;采用间接检测以保护音响外观。
Considering the above factors, Hairis Technology customized a mold tooling according to the shape of the speaker, put the speaker into the tooling mold, and connected it to our instrument. Before starting, select the IPX7 waterproof level test data, press the start button, and let the instrument fill a certain amount of gas into the mold. The gas forms a certain pressure around the product.The product is detected by judging changes in peripheral pressure of the product.
If the sound sealing is not up to standard and air leakage occurs, the leakage value displayed in the instrument will become larger and larger, while the pressure value will decrease.At this time, you can determine whether the speaker is leaking, and the instrument test result will also show NG, which means the seal is not up to standard.If the tested speaker does not leak, the gas in the tooling mold will be in a constant state after inflation, and the pressure and leakage values displayed on the instrument will also be stable, and the instrument test results will showOKwords, indicating that the air tightness test has passed.

五、音响气密性检测仪特性：
1 The leak tester can support leak test methods such as leak test, obstruction test, positive pressure test, negative pressure test, etc. The leak test range-40kpa~150kpa, within this range users can choose according to their own needs.
2 Using a large-size touch screen as the human-machine interface, you can easily monitor the test results and set various parameters during the leak test process.
3 It has an alarm function for qualified and unqualified products, which can eliminate the possibility of manual misjudgment and misdetection.
4 bring4switch input and8The relay output can be controlled by external sensors and switch buttons, and can control external relays, solenoid valves and other actuators to facilitate full automation of testing.
5 Leak meter has200segment user subroutines. By setting the parameters of the subroutine on the touch screen, the user can connect different subroutines in series to form a test process, and use the leakage meter's ownI/OThe interface allows the leak meter to receive control signals from external sensors and control external actuators (relays, solenoid valves, etc.).Thereby automating the testing process.
6 具有测试数据记录功能，可以将测试数据下载到Udisk and displayed via computer.
7. It has a barcode scanning function, which can track and record defective products and repair status; it has a host computer function.
