Sound permeable, waterproof, oil proof, and breathable mold

Possible issues that handheld electronic devices may encounter:

If there is no barrier protection between the speaker and receiver, foreign objects such as water and dust may adhere to the speaker or receiver during long-term use, which will seriously affect the sound quality.

Sometimes handheld electronic devices have to work outdoors in environments with rain and mist, and even underwater. In order to prevent water from seeping into the equipment and affecting the operation of electronic devices, it is necessary to carry out a sealed design.

And the design of airtightness will inevitably affect the sound

The internal pressure changes of electronic devices can quickly have a negative impact on the reliability of electronic components. The above pressure difference is mainly caused by two environmental changes, namely: rapid temperature changes, such as people walking from warm indoor environments with handheld electronic devices to very cold outdoor environments, and the situation of handheld aircraft taking off and landing. These pressure differentials may cause two performance issues:

A sudden drop in external ambient temperature can cause a rapid decrease or increase in internal and external pressure, causing the sealing strip of the shell to withstand significant pressure fluctuations from the external environment. Over time, repeated cycles of high/low pressure will damage the seal, allowing water and pollutants to enter the equipment, leading to equipment failure.

When equipped with water sensitive microphones or receivers, the accumulation of pressure in the sound chamber or sound chamber will cause stress on the microphones or receivers, resulting in distortion or attenuation of sound input or output.

How can Lede solve the problem of preventing rainwater from seeping into the equipment while effectively diverting accumulated air pressure?

The use of Lede waterproof and sound permeable film can effectively solve the problems encountered above

Lede waterproof and breathable film is made of dispersed PTFE resin as raw material, stretched and expanded polytetrafluoroethylene film. This product is composed of multiple small micro pores that are interlocked in three dimensions, allowing gas to freely enter and exit the equipment, and sound can diffuse through the small pores. At the same time, small micropores are smaller than water droplets and dust, thereby preventing water droplets and dust from entering the equipment.

At the same time, the sound emitted by the internal microphone of the equipment causes the vibration of the Lede waterproof and breathable film, which spreads the sound outside the equipment along with the vibration of the Lede waterproof and breathable film; The same external sound can also cause vibration of the Lede waterproof soundproof membrane, and the vibration of the Lede waterproof soundproof membrane will be sensed by the receiver, thereby transmitting external sound into the device.

The three-dimensional small pores of the Lede waterproof and sound permeable film allow air molecules to freely swim, allowing the air pressure inside and outside the equipment to quickly reach equilibrium, effectively relieving the pressure difference caused by temperature and sea level changes, and relieving the stress on the microphone or receiver, achieving high fidelity sound transmission.
