Background technology
No matter in city or in rural area, sound wave is ubiquitous.Particularly, in the road of airport, factory and prosperity, in air, be full of various sound, formed ubiquitous noise pollution.
As everyone knows, sound wave is also a kind of energy, still, in life, in various sound, only has a very little very little part for people is heard, and major part is all gradually to consume in air.If can be used, turning waste into wealth, will be a kind of energy source endlessly.Among prior art, still do not find to utilize the device of acoustic wave generation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of to turn waste into wealth, and can utilize the piezoelectric type sound generator of acoustic wave generation.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A piezoelectric type sound generator, comprises sense acoustic device and the current rectifying and wave filtering circuit being electrically connected to sense acoustic device, it is characterized in that, described sense acoustic device is connected to form by a plurality of piezoelectric ceramic pieces; Described current rectifying and wave filtering circuit comprises the first filter capacitor C1 and transformer T, and transformer T exports rectifier to, and rectifier inputs to storage battery or power consumer apparatus by the electric current of output after the second filter capacitor C2, the 3rd filter capacitor C3 filtering.
According to the present invention of said structure, a plurality of piezoelectric ceramic pieces are to be connected in parallel.
According to the present invention of said structure, a plurality of piezoelectric ceramic pieces are to be connected in series.
According to the present invention of said structure, piezoelectric ceramic piece is provided with cavity behind.
According to the present invention of said structure, described rectifier is transformation bridge rectifier.
According to the present invention of said structure, in described current rectifying and wave filtering circuit, also comprise voltage stabilizing circuit.
The present invention is novel in design, simple in structure, practical, can directly be installed on the larger occasions such as road of airport, factory, karaoke halls and sound that noise is larger, and noise sound wave is converted to electric energy output, and energy-conserving and environment-protective, turn waste into wealth.
