Abstract

The invention discloses a microphone structure and electronic equipment, and the structure comprises a sound sensing element which is provided with a first sound hole; a protective shell which forms asealed protective cavity outside the first sound hole, wherein a second sound hole is formed in the protective shell; a waterproof membrane which is fixed in the protective cavity, wherein the protective cavity is divided into a first cavity body communicated with the first sound hole and a second cavity body communicated with the second sound hole by the waterproof membrane; an elastic sealing element, wherein one end of the elastic sealing element is fixed around the second sound hole, and the other end of the elastic sealing element is fixed with a component applied by the microphone structure. The elastic sealing element is in a compressed state, the sound sensing element is provided with a protruding part surrounding the protective shell, the top of the protruding part makes contactwith a component applied by the microphone structure, and the compression amount of the elastic sealing element is limited by the height of the protruding part. One technical effect of the invention is that foreign matters are prevented from influencing or damaging elements in the microphone by separating the elements in the microphone structure from the outer part.

Description

technical field [0001] The present invention relates to the technical field of acoustics and electricity, and more specifically, relates to a microphone structure and electronic equipment. Background technique [0002] A microphone is a transducer that converts sound into electrical signals, and there are many sophisticated components inside the microphone. The microphone is suitable for use in a variety of complex environments. When working in different environments, the microphone will be affected by different foreign objects, which will reduce the performance of the microphone or damage the microphone. [0003] In the working environment of the microphone, there may be dust, liquid, strong air flow, static electricity and other foreign objects that affect the normal operation of the microphone. For example, if dust or liquid enters through the sound hole of the microphone, it touches or enters the components inside the microphone. This will affect the performance of th...
