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

Acoustic cavity sealing testing

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 protectionverification

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

Heatdissipation system sealing evaluation

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