Description

Silicon microphone convenient for butt joint of protective shells Technical Field The utility model relates to a silicon microphone convenient for butt joint of protective shells, and belongs to the technical field of silicon microphones. Background The silicon microphone is mainly based on capacitive sensor technology, a thin film in a silicon structure vibrates along with sound to generate a changed capacitance, a second polar plate of the capacitor is positioned on a fixed surface in silicon, a charge pump in the IC generates high direct current voltage for the capacitor, and an IC circuit converts the capacitance change into an electric signal representing an audio signal on the MEMS film. All microphones are analog audio in their initial signals, which weak signals need to be amplified by a pre-amplifier and then converted into analog or digital signals by an integrated dedicated circuit. The Chinese published patent (publication number: CN 216565592U) discloses a silicon microphone convenient for butt joint of a protective shell, which comprises a circuit board, wherein an amplifier is arranged on the surface of the circuit board, a silicon microphone chip is arranged on one side, close to the amplifier, of the circuit board, a protective shell body is arranged at the top of the circuit board, the amplifier, the silicon microphone chip and the protective shell body are formed by a foundation of the silicon microphone, a butt joint seat is arranged on the outer side, close to the amplifier and the silicon microphone chip, of the circuit board, a butt joint groove is formed in the inner wall of the bottom end of the protective shell body, and welding strips are arranged on the outer side of the protective shell body.
