Description

technical field [0001] The invention relates to the technical field of electrostatic protection, in particular to a microphone electrostatic protection structure and electronic equipment. Background technique [0002] When electronic equipment uses a microphone, it usually wraps the microphone with a silicone-like soft structure, leaving only the position of the sound hole of the microphone for convection with the outside air, so that the sound can only be transmitted to the microphone along one direction of the sound hole of the silicone part, and the other direction The sound is isolated, so that the silicone part can seal the microphone in other directions except the sound hole. Since the silicone part is insulating, when the external static electricity is high, the static arc will directly guide the microphone body along the sound hole of the silicone part of the microphone. Destroy the internal diaphragm and ASIC chip of the microphone, resulting in failure of the micro...

Problems solved by technology

[0002] When electronic equipment uses a microphone, it usually wraps the microphone with a silicone-like soft structure, leaving only the position of the sound hole of the microphone for convection with the outside air, so that the sound can only be transmitted to the microphone along one direction of the sound hole of the silicone part, and the other direction The sound is isolated, so that the silicone part can seal the microphone in other directions except the sound hole. Since the silicone part is insulating, when the external static electricity is high, the static arc will directly guide the microphone body along the sound hole of the silicone part of the microphone. Destroy the internal diaphragm and ASIC chip of the microphone, resulting in failure of the microphone performance

[0003] At present, the solution to this kind of poor static protection is to stick a layer of conductive material on the microphone body, such as copper foil, aluminum foil, etc., and connect the conductive material to the ground terminal in the circuit. , will be guided by conductive materials to the grounding terminal of the circuit, and will not enter the interior of the microphone body, which serves the purpose of protecting the microphone body. However, due to the high precision requirements and complicated manufacturing process when attaching conductive materials, it is difficult to realize automatic production and other costs. Low manufacturing process, coupled with the high cost of conductive materials themselves, resulting in the price of the final product is not advantageous
