Mic Vent

Diversified application scenarios have given rise to a strong demand for waterproof functions.

With natural hydrophobic properties thanks to its multi-fluorine molecular structure, IPRO mic vent is mainly made of ePTFE and installed at the mic sound hole of the smartphones to maintain a perfect call function when the smartphone is immersed in water, and prevent phones from damages in case of accidental water exposure.

Product Application : Mic Vent

Introduction

With consumer electronics growing more popular by the day, the mobile phone industry has entered a highly competitive phase.

 

As consumers require mobile phones to adapt to challenging scenarios, water resistance has become a must-have feature for high-end phones. Top 3 manufacturers are offering IPX7 and IPX8 certified flagship models that can stand 4-6m water depth. Waterproof functions are expected to become standard configurations for all mobile phones in the next 3 to 5 years.

 

Acoustic devices such as high sensitivity microphones and speakers are necessary components for smart phones’ phone call functions. In order to realize smooth sound transmission, a sound hole must be created. How to achieve high level of waterproof for the sound hole while maintain sound transmission quality has become the technical difficulty for designers.

 

With its natural hydrophobicity, good ductility, and vibration ability, ePTFE mic vents perfectly protect mic sound hole from water while maintaining excellent acoustic transmission.

 

By installing the IPRO mic vents on the housing hole, the whole product can be immersed in deep water without breaking. At the same time, IPRO mic vents reduce the loss of sound transmission to less than 1dB thanks to its excellent ductility and exquisite vent-making technology, realizing nearly zero loss in tone transmission.

 

With the dual protection of waterproofness and tone transmission, consumers will no longer worry about the damage of smart phones due to water exposure.
