Abstract
The utility model discloses a sound-electricity transformation apparatus. The apparatus comprises a piezoelectric ceramic, an electricity storage device and a switch, wherein the piezoelectric ceramic, the electricity storage device and the switch are electrically connected, forming a series circuit. The beneficial effects of the utility model are that, collected noises can be transformed into utilizable electric energy, so that the sound-electricity transformation is achieved, changing waste into valuables.
Description
Technical field
The utility model relates to a kind of acoustic-electric conversion equipment, belongs to the acoustic technique field.
Background technology
The present underground space of sealing such as in subway and tunnel, because the reverberation time of noise is longer, cause large about 20 decibels of noise acoustic ratio ground, serious harm traffic safety and passenger's physical and mental health, therefore, it is imperative that noise is controlled, and the main method of using porous material to carry out noise reduction by absorption is eliminated noise at present, has caused to a certain extent the waste of the energy.
Summary of the invention
In order to solve the problem of the energy waste that present direct employing porous material noise reduction causes, the utility model proposes and a kind ofly can convert the noise that produces to electric energy, simple in structure, easy to use, reusable acoustic-electric conversion equipment.
Acoustic-electric conversion equipment described in the utility model is characterized in that: comprise piezoelectric ceramic, electrical storage device and switch, described piezoelectric ceramic, described electrical storage device and described switch are electrically connected, and form the loop of series connection.
The size of described piezoelectric ceramic is adjusted according to the noise sound intensity.
Described piezoelectric ceramic is vertical with the route of transmission of noise.
During use, whole acoustic-electric conversion equipment is installed in the noise compact district, opening switch, so that the loop that piezoelectric ceramic, electrical storage device and switch form is connected, this moment, piezoelectric ceramic contacted with noise, and noise produces pressure to it, produced Voltage force at the piezoelectric ceramic two ends poor, thereby the electrical storage device charging reaches the conversion of acoustic-electric; After being full of electricity, electrical storage device in time changes other electrical storage device.
The beneficial effects of the utility model are: convert the noise of collecting to utilizable electric energy, realize the conversion of acoustic-electric, turn waste into wealth.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
