Problems solved by technology

[0004] The sound receiving mechanism in the prior art generally adopts a metal diaphragm. Due to its own physical characteristics, the metal diaphragm will produce echoes and tremors when collecting sound waves, resulting in poor sound reception. Therefore, it is necessary to develop a new sound receiving device. , improve its radio fidelity

Abstract

The present invention relates to a high-fidelity factor radio device which comprises a sound receiving piezoelectric body, wherein the sound receiving piezoelectric body is provided with an electrodelayer; the electrode layer is provided with a sound receiving piezoelectric layer; the sound receiving piezoelectric layer is provided with an acoustic wave acquisition matrix; a graphene layer is used as a receiving piezoelectric layer, and graphene is the newest nanomaterial being the thinnest, the greatest in strength and the strongest in conductivity; graphene itself is large in brittleness and hardness, and has good mechanical wave conduction effect such as sound waves; and there is no attenuation in the backhaul of the echo and the piezoelectric effect, which improves the conduction resolution and echo fidelity factor of the acoustic wave acquisition matrix.

Description

technical field [0001] The invention relates to a sound collecting device, in particular to a sound receiving device with a higher fidelity rate. Background technique [0002] With the continuous reduction in volume and continuous improvement of performance of electronic products, people have higher and higher requirements for the volume and performance of radio equipment used in electronic products. At present, the mass-produced electret condenser microphone radio equipment is mostly a three-layer circuit board structure connected by fixing glue or a packaging structure in which a circuit board is added with a metal casing. These types of radio equipment have complex structures, low sensitivity, and weak anti-noise performance. [0003] Graphene is a two-dimensional carbon material, which is a two-dimensional crystal with only one layer of atomic thickness, which is exfoliated from graphite material and composed of carbon atoms. It is a new type of nano-material that is c...
