Introduction

With the popularity of intelligent wearable products, traditional wearable products (such as mechanical watches, etc.) are gradually being replaced. Smart wearables have also derived from single-function bracelets into a variety of products, including smart sports watch, children’s watch, TWS headphones, and health monitoring watch for the elderly, etc.

 

Wearable products are used daily and widely, thus are inevitably exposed to hand sanitizers, sweats, rainwater, and other liquids. Therefore, being waterproof and resistant to corrosive liquids becomes vital for wearable products. Today, waterproofness has become a standard function of wearable products. Health monitoring watches, children’s watches and sports watches are often used during swimming and diving. 50m diving-grade waterproof capabilities has gradually become a potential necessity for intelligent wearable products.

 

Generally, smart wearable products are interconnected with mobile phones to realize communication functions and receive phone calls and information, so highly sensitive acoustic devices such as microphones and speakers must be integrated into the wearables. In order to achieve smooth sound transmission, sound holes need to be created for wearables. The pressure of 50 meters underwater reaches 500kPa, and ordinary elastic materials cannot withstand such pressure, thus how to be waterproof but also ensures sound transmission has become a technical difficulty for wearable products.

With natural hydrophobic properties, high strength and vibration capabilities, the ePTFE mic vent provides wearable products with waterproof protection, which can stand water depth of 30m for 30 min without breaking, as well as maintain perfect sound transmission.

In addition, thanks to excellent ductility of the material and IPRO’s exquisite filming technology, the loss of sound transmission is reduced to less than 5dB, realized close to zero loss of sound quality.

 

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