The creation department is related to a microphone, and more specifically, a surface-mounting waterproof and wind-proof three-dimensional structure applied to a planar hidden microphone of an electronic device, so that the microphone electronic device has better anti-wind noise effect, thereby improving Sound quality, and can provide protection against rainwater infiltration into the microphone electronics.

Press, the microphone name is a microphone, which is an energy conversion device that converts a sound signal into an electrical signal, which is translated by Microphone. Also known as a microphone, a microphone (which includes a microphone used for a sound reinforcement system like singing, and a built-in (hidden) microphone that fits into the body of the machine, the microphone body does not protrude from the machine surface, Such as the general mobile phone, tablet, digital camera microphone, used for recording and recording; the microphone is initially converted into an inductive and capacitive conversion through the resistance conversion of sound and sound, including aluminum ribbon, moving coil and other microphones, as well as condenser microphones and Electret microphone (ECM). Most of the microphones are ECM (Electret Microphones), which use a polymeric material diaphragm with permanent charge isolation. This technology has been around for decades, and recently a microelectromechanical microphone (MEMS) has been developed with a small size. Low-interference advantages; however, regardless of the form of the microphone, it is desirable to reduce the wind noise caused by the wind blowing the air to disturb the microphone diaphragm, because the wind directly blows into the microphone diaphragm to generate the amplitude (noise) /Noise), far more than the amplitude of the sound wave (signal/signal) of the object to be radioned, resulting in only the wind The result of noise.

However, it is generally known that an external windshield (generally known as a sponge cover) is placed on the external (independent of the machine outside) microphone body, and the porous hole structure is used for collecting and reducing the wind blowing into the microphone. The resulting wind noise, even more so-called filter cover will be another kind of hairy structure, can suppress the noise generated by the wind, make the recorded sound more clean and clear, but the filter cover is porous structure The sponge cover or the hairy full-face windshield must be covered by the microphone body to be fixed, and it is afraid of being wet by rain when the outdoor rains, especially the hydrophilicity and capillary phenomenon of the sponge cover material will actively absorb water, when the water Inhalation of the sponge causes the porous structure to be closed to the microphone receiving guide hole, the sound is not transmitted into the microphone to cause the sound to be unreceived, or the water liquid is infiltrated into the microphone electronic device, which may cause damage to the microphone electronic device.
