Abstract

The invention discloses a microphone and electronic equipment. The microphone comprises a shell, wherein an accommodating cavity is formed in the shell, and the shell is further provided with a sound hole communicated with the accommodating cavity; a circuit board which is arranged at one end, far away from the sound hole, of the accommodating cavity; an annular magnet which is accommodated in the accommodating cavity and is fixedly connected with the cavity wall of the accommodating cavity; and a vibration assembly which is connected with the annular magnet and electrically connected with the circuit board, wherein at least part of the vibration assembly is located on the inner side of an annular space defined by the annular magnet, the vibration assembly is arranged towards the sound hole, and audio frequency can penetrate through the sound hole to enter the containing cavity, and the vibration assembly is driven to vibrate in the accommodating cavity, so that the vibration assembly cuts magnetic induction lines to generate current signals. The technical scheme of the invention aims to improve the acoustic performance and prolong the service life of the microphone.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a microphone and electronic equipment using the microphone. Background technique [0002] With the popularization of automobile intelligence, the application of on-board electronic equipment is becoming more and more frequent. Among them, in the field of automatic driving, microphones are needed to collect the sound in the environment to provide reference for automatic driving. The electret microphone is small in size and takes up little space, and is suitable for installation on the car body. [0003] Since the electret microphone in the related art includes structures such as a back plate, a circuit board, a diaphragm and a gasket, the back plate stores charges and together with the spacer and the diaphragm form the capacitive plate part of the electret microphone. Therefore, the structure of the electret microphone is relatively complicated. And when the sound i...
