ATEQ is Available to Provide Consulting and Leak Testers For Waterproof Speaker Leak Testing Applications.
Waterproof speakers are becoming more mainstream because people want to use them outside in the elements, on the boat or during a sweaty workout. Whether it’s a wireless bluetooth speaker or a pair of headphones or earbuds, if the product claims to be waterproof or water resistant, it needs to be properly leak tested to get a certified IP rating.
Waterproof speaker manufacturers use a variety of sealing techniques to make sure all potential points of least resistance are watertight in order to keep all of the electrical components inside safe and functioning. Sometimes sealing is as straight forward as strategically using glue in the connection ports. Areas like headphone jacks and charging ports use rubber rings to seal the enclosures. Bluetooth speaker buttons often have a silicon rubber boot to separate the button from the electrical contacts within the speaker. On areas that need to keep water out but let air pass through, like microphones and speakers, manufacturers use a water-resistant breathable mesh fabric membrane to act as a pressure vent.
These seals, membranes and ports all need to go through rigorous quality testing. The most important type of testing for the waterproofing process is leak testing. Waterproof speaker manufacturers have dozens of leak testers throughout their production lines to test the speaker at various points during the assembly process. As each port is added to the speaker, it can be leak tested with a differential pressure decay leak tester. This technology pressurizes the part with compressed air and measures the pressure drop, which would signify the air leak rate in that port. Once the speaker is completely assembled it can be leak tested with ATEQ’s sealed component ingress leak testing method. By putting the completed sealed speaker into an airtight chamber, the chamber can be pressurized with compressed air and the leak tester can measure if any air sinks into the speaker beyond the specified leak rate.
