We provide accurate testing for the three core systems of audio and video appliances:

Acoustic cavity seal detection

Evaluate the sealing of the speaker unit and the cabinet to ensure the airtightness of the acoustic cavity and ensure low-frequency response and sound quality purity.

Electronic component protection verification

Detect the sealing effect of the joint surface and interface parts of the equipment shell to meet the IP protection level requirements and prevent the intrusion of dust and moisture.

Thermal system seal assessment

For the heat dissipation channels of high-power amplifiers and other equipment, verify the rationality of their sealing design and balance the needs for heat dissipation and dust prevention.
