Problems solved by technology

[0004] Since the MEMS back cavity is formed by the MEMS transducer, and the shape and size of the MEMS transducer are limited by the height of the MIC, the size of the MEMS cavity is limited
Thereby reducing the signal-to-noise ratio of the data collected by the microphone, and reducing the integration of the mobile terminal

Abstract

The invention refers to the technical field of microphone packaging and particularly relates to a MEMS (Micro-Electro-Mechanical system) microphone monomer. The MEMS microphone monomer comprises an outer cover with an acoustic through hole, wherein the inside of the outer cover is connected and provided with a plurality of metal contact points through an insulation device; a base plate and the outer cover are formed to be an acoustic cavity, wherein the acoustic comprises a MEMS energy converter and an ASIC (application specific integrated circuit) slice. The MEMS microphone monomer has the following advantages: the ASIC slice and the MEMS energy converter are respectively and fixedly arranged in the acoustic cavity formed by the base plate and the outer cover through the metal contact points on the insulation device, so that the MEMS energy converters forms an acoustic back cavity at a sealing space formed in the acoustic cavity; furthermore, the acoustic back cavity of the acoustic back cavity is not limited by the cavity body of the MEMS energy converter; and thereby, the back cavity of the MEMS energy converter is greatly increased, and a signal noise ratio collected by the microphone is improved.

Description

technical field [0001] The invention relates to the technical field of microphone packaging, in particular to a MEMS (Micro-Electro-Mechanical System) microphone monomer. Background technique [0002] With the progress of society and the development of technology, in recent years, as the volume of electronic products such as mobile phones and notebook computers has been continuously reduced, people have higher and higher requirements for the performance of these portable electronic products, which also require matching electronic products. Parts continue to shrink in size, performance and consistency. In this context, as one of the important parts of the above-mentioned portable electronic products, many new products have been introduced in the field of microphone products, among which MEMS microphones (also known as silicon microphones) realized in batches using semiconductor manufacturing and processing technology are representative. product. [0003] Existing common MEM...
