Abstract

The invention relates to the audio equipment technology field, especially to a microphone. The microphone comprises battery lead plates and thin films, wherein the surfaces of the thin films have electrostatic charges. The battery lead plates are current-conducting plates and a plurality of through holes are formed in the battery lead plates. Insulating holders are arranged between the two battery lead plates. Besides, the thin films are arranged between the two battery lead plates, wherein the surfaces of the thin films have the electrostatic charges, so that a voice and electricity conversion integrated apparatus is formed. According to the invention, the structural design of the microphone is simple and scientific and a traditional structural mode is broken through; there is no need to independently provide power for the microphone, so that electric energy is saved; it is convenient for assembling; and products with various appearances can be formed.

Description

Technical field: [0001] The invention relates to the technical field of audio equipment, in particular to a microphone. Background technique: [0002] Microphone, scientifically called microphone, is an energy conversion device that converts sound signals into electrical energy signals, also known as microphones and microphones. In the 20th century, the microphone developed from resistive conversion of sound and electricity to inductive and capacitive conversion, and a large number of new microphone technologies gradually developed, including aluminum ribbon, dynamic coil and other microphones, as well as the widely used condenser microphones and electret microphones. body microphone. [0003] Dynamic microphones (such as figure 1 shown), the basic structure includes three parts: coil 1A, diaphragm 2A, and permanent magnet 3A. When the sound wave enters the microphone, the diaphragm vibrates under the pressure of the sound wave, and the coil 1A connected with the diaphrag...
