Problems solved by technology

[0002] At present, sound wave power generation is a new type of power generation method, which is still in the development stage, and there are not many sound-to-electricity conversion systems that can be applied to production and life.
However, more acoustic and electrical equipment used for sound collection and sensing only focus on sound quality and real output, and cannot collect and make full use of the energy in sound.
Some known devices that generate electricity through sound energy have the following disadvantages: 1) the number is small and most of them have complex structures, or the volume is large, which is not convenient for wide application
2) Most of the existing acoustic-electric conversion technologies cannot effectively convert acoustic energy and electrical energy
3) Even if it can be converted, it is limited to electrical signals, and cannot generate actual electrical energy that can be output and applied

Embodiment 1

[0044] In areas with relatively high noise, such as an airport, multiple sound wave generators are installed on the metal plate, and the sound wave generators face the sound source. The paper cone 2 of the acoustic wave generator vibrates to a certain extent due to the action of sound energy such as noise, and then drives the synchronous vibration of the generating coil 5, so that the vibration of the generating coil 5 cuts the magnetic field lines of the magnet 7, and generates electrical energy. The generated electric energy is transmitted to the power transmission target device 10 through the power transmission wire 6 . Since a plurality of acoustic wave generators work together, the currents output by the plurality of acoustic wave generators can be fed into the same power transmission target device 10 . Then, the integration of the power transmission target device 10 is output to the power supply device.

Embodiment 2

[0046] The acoustic wave generator is arranged on or inside the shell of complex large-scale mechanical equipment without affecting the work of the mechanical equipment. The acoustic wave generator collects the noise emitted by the mechanical equipment, converts it into an electrical signal and outputs it to the power transmission target equipment 10, and provides computer analysis and processing, that is, compares the collected actual electrical signal with the reference electrical signal preset in the computer. The signals are compared, and the preset reference electrical signal is obtained by collecting and converting the mechanical equipment when it is working normally. Therefore, the characteristics of the actual electrical signal are analyzed by the computer to judge whether the mechanical equipment is working normally.

Description

technical field [0001] The invention relates to the field of sound wave technology, in particular to a sound wave generator with an elastic position correction function. Background technique [0002] At present, sound wave power generation is a new type of power generation method, which is still in the development stage, and there are not many sound-to-electricity conversion systems that can be applied to production and life. However, more acoustic and electrical equipment used for sound collection and sensing only focus on sound quality and real output, and cannot collect and make full use of the energy in sound. Some known devices for generating electricity through sound energy have the following disadvantages: 1) The number is small and most of them have complex structures, or are large in size, which is not convenient for wide application. 2) Most of the existing acoustic-electric conversion technologies cannot effectively convert acoustic energy and electrical energy. ...
