The waterproof audio can be used outdoors in humid environment such as stream, seaside, yacht and swimming pool. Users can enjoy the pleasure brought by music. In order to achieve the specified waterproof level of sound, all waterproof speakers need to be tested for tightness. Today, a sound manufacturer found Harris technology, hoping to customize our sound tightness tester. However, this product customization needs to be combined with radium engraving machine. The following is the product solution and case demonstration.
Hermetic sound tightness tester
OneDifficulties in customization of sound tightness tester
In order to save testing space and production time, customers hope to mark the qualified products in combination with the factory's current laser engraving machine after the products are qualified. After understanding, we found that the volume of the laser engraving machine is large. If we want to combine with the sealing detector, we need to use the cabinet shape. Whether it is wiring or placing, we should not close to each other, so as to achieve the function of independent use and switching.

2Design of sound tightness detector
After detailed product understanding and communication, hiris technology combined with the actual situation of customers, to help customers develop a sound tightness detection scheme, and designed a sound tightness detector combined with radium engraving machine.

ThreeTest process of sound tightness tester
This sound tightness tester uses compressed air as the detection medium, with positive pressure and negative pressure as the detection method. According to the force direction of the product, the positive pressure (blowing) or negative pressure (suction) can be selected for direct test, so as not to damage the appearance of the product.
During the test, the instrument will inflate. If the sound is not sealed, there will be air leakage, and the gas will leak to the other end. At this time, the leakage value in the instrument will display more and more data, and the pressure value will drop. At this time, it can be determined that the sound is leaking, and the instrument test results will also show ng. If the test sound 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 test result of the instrument will be displayedOKThe words indicate that the sound has passed the air tightness test.

FourIntroduction to basic functions
1Large size touch screen is used as the human-machine interface, which can easily monitor the test results and set various parameters in the process of waterproof test.
2It has the alarm function of qualified and unqualified products, which can eliminate the possibility of manual misjudgment and misinspection.
3, band4Circuit switch input and output8It can accept the control of external sensors and switch buttons, and can control the external relay, solenoid valve and other executive components, so as to realize the full automation of the test conveniently.
4Waterproof testertwo hundredBy setting the parameters of the subprogram on the touch screen, the user can connect different subprograms in series to form a test processI/OThe interface enables the leakage meter to receive control signals from external sensors and control external actuators (relays, solenoid valves, etc.). So as to realize the automation of the test process.
5, with test data recording function, you can download test data toUDisk, and through the computer display.
6With bar code scanning function, it can track and record defective products and repair situation; The function of upper computer.
