Embodiment Construction

[0011] The black phosphorus diaphragm microphone of the present invention will be described in detail with reference to the accompanying drawings. attached figure 1 Shown, the black phosphorus diaphragm microphone of the present invention comprises: single-layer black phosphorus thin film is used as diaphragm 1, is used for carrying out acoustic-electric conversion, and this single-layer black phosphorus thin film can use mechanical layer stripping method or other chemical methods to obtain; At least two An electrode 2, fixedly connected with the diaphragm, is used to supply power to the diaphragm and transmit signals; a power supply and amplification unit 3 is used to supply power to the diaphragm and amplify and output the signal; there is a gap between the power supply and amplification unit 3 and the electrode 2 Electrical connection 4.

[0012] The working principle of the microphone of the present invention is that the black phosphorus diaphragm 1 vibrates with the chan...

Abstract

The present invention provides a microphone. The microphone comprises a diaphragm (1) for sound-electricity conversion, at least two electrodes (2) fixedly connected with the diaphragm and used for powering the diaphragm and transmitting a signal, and a powering and amplifying unit (3) for powering the diaphragm and amplifying and outputting the signal. An electric connection (4) is between the powering and amplifying unit (3) and the electrodes (2). The microphone is characterized in that the diaphragm (1) is made of a black phosphor material. Compared with the existing microphones, the black phosphor diaphragm microphone is greatly improved in sensitivity, frequency response, transient response and other electroacoustic characteristics.

Description

technical field [0001] The invention belongs to the field of microphone components, in particular to a black phosphorus diaphragm microphone. Background technique [0002] The materials of the microphone diaphragm in the prior art are usually polymer materials, polymer materials with metal coating, metal, etc. Due to the limitation of materials, the performance of the microphone still cannot meet the increasingly stringent use requirements sometimes. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention proposes a microphone with a diaphragm made of black phosphorus. The electroacoustic characteristics of the microphone, such as sensitivity, frequency response, and transient response, can be greatly improved compared with existing microphones. [0004] Provided is a microphone, comprising: a vibrating membrane for performing acoustic-electric conversion; at least two electrodes fixedly connected to the vibrating membran...
