The usage scene of waterproof speakers is positioned outdoors and can be used in humid environments such as streams, seasides, yachts, swimming pools, etc. Users can enjoy the pleasure brought by music.In order to achieve the waterproof level specified by the audio, all waterproof speakers must be tested for sealing. Today, an audio manufacturer approached Hirays Technology and wanted to customize our audio sealing tester. However, this product customization needs to be used in conjunction with a laser engraving machine. The following is a demonstration of this product solution and case.

one.Difficulties in customizing audio sealing testers
In order to save testing space and production time, the customer hopes that after the product passes the test, the factory's current laser engraving machine can be used to mark the qualified product.After understanding, we found that the laser engraving machine is large in size. If it is to be combined with a sealing tester, it needs to be in a cabinet shape. Both wiring and placement must be independent of each other to achieve independent use and switching functions.

two.Design of audio sealing tester
After detailed product understanding and communication, Hirays Technology combined the customer's actual situation to help the customer formulate a sound sealing test plan, and designed a sound sealing tester for use with the laser engraving machine.

three.Audio sealing tester testing process
This audio sealing tester uses compressed air as the detection medium, and combines positive pressure and negative pressure as the detection method.Positive pressure (blowing) or negative pressure (inhalation) can be selected according to the force direction of the product for direct testing without damaging the appearance of the product.
During testing, the instrument is inflated.If the speaker is not sealed and air leakage occurs, the gas will leak to the other end. At this time, 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 that the speaker is leaking, and the instrument test results will also show NG.If the tested speaker does not leak, the gas will be in a constant state after inflation, the pressure value and leakage value displayed on the instrument are also stable, and the instrument test results will showOKwords, indicating that the speaker has passed the air tightness test.

Four.Introduction to basic functions
1, Using a large-size touch screen as the human-machine interface, you can easily monitor the test results and set various parameters during the waterproof test process.
2. It has an alarm function for qualified and unqualified products, which can eliminate the possibility of manual misjudgment and misdetection.
3,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.
4, waterproof tester 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.
5, with test data recording function, the test data can be downloaded toUdisk and displayed via computer.
6, with barcode scanning function, which can track and record defective products and repair status; host computer function, etc.
