MICROPHONE AND ELECTRONIC DEVICE WITH MICROPHONE Russian patent published in 2023 - IPC H04R1/28 

FIELD: acoustics; microphones.

SUBSTANCE: microphone includes a housing for receiving vibration signals; a conversion component inside the housing for converting vibration signals into electrical signals, the conversion component including: a converter; damping film, attached to the converter; and an elastic element, wherein said at least one damping film is connected to the transducer and at least one said elastic element, respectively; and a processing circuit for processing electrical signals. The damping film is located on at least one surface of the transducer at a predetermined angle. The damping film is not connected to the housing. It is possible to use two damping films, wherein said at least two damping films are arranged symmetrically with respect to the center line of the transducer.

EFFECT: increase in sensitivity, obtaining smooth amplitude-frequency characteristics and a wide frequency band.
