in the market, consumers have higher and higher requirements for products related to sound. There are more andmore products that are easy to enter water and have requirements for sound transmission,such as mobile phones,walkie-talkies, car horns, buzzers, GPS, outdoor speakers and other equipment.In order to protect products fromwater, dust, dirt and impurities, engineers also want to do countless methods! In the end, there is no guarantee thatthe sound is transmitted high quality!

In order to solve this problem, SDA Shangda’s dustproof and waterproof sound-permeable membrane effectivelysolves the above problems. The high airflow of SDA Shangda’s dustproof and waterproof sound-permeablemembrane can prevent the internal pressure accumulation during the operation of the equipment. This reduces therisk of premature device failure and ensures that the device consistently delivers superior sound throughout its lifecycle. At the same time also has the following advantages.
1. Low acoustic resistance brings continuous high quality sound transmission2. Reliable dust and metal particle protection reaches IP6x standard, more durable
3, excellent immersion protection to IP68, more reliable
4. Optimal acoustic performance, tailor-made design and thickness5. Strong adhesive, easy to install
