Abstract
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...
