The Materials of Microphone Vibrating Diaphragm Film

Metallic Polyester Film is a typical material for making Microphone Vibrating Diaphragm Film and Microphone Membranes .

The metallized PET film has good reflection ability to ultraviolet ray and infrared ray, can achieve the function of blocking ultraviolet ray, at the same time can make the film to improve the oxygen, moisture, and has the metallic luster.

Metallized Polyester Film is a barrier film formed by depositing a thin layer of aluminum atoms onto high-quality PET Film by vacuum aluminum plating process. It has bright metal gloss, excellent gas and light barrier and good moisture-proof,heat-resistant and puncture resistance.

The thickness of Microphone Vibrating Diaphragm Film usually less than 5 microns. The diaphragm Film needs to be electrically conductive and extremely thin, and the ultra-thin aluminized Polyester Film serves both needs well. This mylar is thin and strong enough to be an effective diaphragm material! The microphone vibration diaphragm is a thin film that moves in response to sound pressure changes (sound waves). Without a movable diaphragm, a microphone would not be able to do its job as a transducer.
