Abstract
The invention discloses a charging device capable of realizing sound-electricity conversion. The charging device comprises a stand column support, wherein a support surface is arranged at the bottom of the stand column support, a sound collector is arranged at the top of the stand column support, piezoelectric ceramic is mounted in the sound collector, a storage battery is arranged in the stand column support, an input end of the storage battery is connected with the piezoelectric ceramic through a line, and an output end of the storage battery is connected with a charging end through a line. The piezoelectric ceramic generates voltage difference at two ends under the pressure of noise so as to charge the storage battery. The external charging end is charged by the storage battery after accessing a low-voltage electric appliance, energy of the noise is converted into electric energy to be stored and charge the external electric appliance in the whole process, the noise is effectively utilized, the charging device realizes sound-electricity conversion, the noise is turned into wealth, noise in a public place can be absorbed, the effect of the noise on people is reduced, the low-voltage electric appliance can be charged, and the public can charge conveniently.
Description
Technical field
The present invention relates to a kind of acoustic-electric convert charging device, belong to acoustic technique and energy-conserving and environment-protective field.
Background technology
Noise is the accessory substance in human being's production life, the existence of noise brings new problem to the productive life of the mankind, in order to reduce the impact of noise, a lot of experts and scholars have carried out extensive research to noise-reduction method and approach, from the angle of the energy, noise is also a kind of energy, but fails to be utilized effectively.
The space that current noise can be used directly is more limited, and processes noise, and converting the energy that the mankind can directly utilize to is the effective way be used to noise, such as noise is converted to mechanical energy, electric energy etc.
Summary of the invention
The object of the invention is: for the defect of prior art, there is provided a kind of acoustic-electric convert charging device, piezoelectric ceramic produces voltage difference because being subject to the pressure of self noise at two ends, and then charges a battery, external charging termination is charged to it by storage battery after entering low-voltage electrical appliance.In whole process by the power conversion of noise be electric energy and store and to outside electrical appliance charging, realize effective utilization of noise, to overcome the deficiencies in the prior art.
Technical scheme of the present invention
A kind of acoustic-electric convert charging device, comprise column support, bottom column support, supporting surface is set, at column support top, sound collector is set, in sound collector, piezoelectric ceramic is installed, in column support, arrange storage battery, the input of storage battery and piezoelectric ceramic are by connection, and connection is passed through in output and the charging end of storage battery.
In aforesaid a kind of acoustic-electric convert charging device, the circuit between the input and piezoelectric ceramic of storage battery arranges safety switch, safety switch for the protection of storage battery, avoid storage battery be full of electricity after continue power supply and there is excessive pressure damages.
In aforesaid a kind of acoustic-electric convert charging device, the shape of described sound collector adopts hemisphere, and the shape for the sound collector of reception environment noise adopts hemisphere, so that the sound source of multiple directions in reception environment.
In aforesaid a kind of acoustic-electric convert charging device, described charging end is the charger interface of low-voltage electrical appliance, and align with supporting surface in the position of this charging end, external charge end is the charger interface of conventional low-voltage electrical appliance, can realize charging to different low-voltage electrical appliance, supporting surface is connected with apparatus main body, for placing low-voltage electrical appliance.
Owing to have employed technique scheme, compared with prior art, in the present invention, piezoelectric ceramic produces voltage difference because being subject to the pressure of self noise at two ends, and then charges a battery.After external charging termination enters low-voltage electrical appliance, charged to it by storage battery, in whole process by the power conversion of noise be electric energy and store and charge to outside electrical appliance, realize effective utilization of noise, the present invention realizes acoustic-electric conversion, is turned waste into wealth by noise, the noise of public place can be absorbed, reduce the impact of noise on human, can be low-voltage electrical appliance charging, facilitate the public to supplement electricity in time.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is principle schematic of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, but not as any limitation of the invention.
Embodiments of the invention: a kind of acoustic-electric convert charging device, comprise column support 7, it is characterized in that: supporting surface 6 is set bottom column support 7, at column support 7 top, sound collector 1 is set, the shape of this sound collector 1 adopts hemisphere, in sound collector 1, piezoelectric ceramic 2 is installed, storage battery 4 is set in column support 7, input and the piezoelectric ceramic 2 of storage battery 4 pass through connection, circuit between the input and piezoelectric ceramic 2 of storage battery 4 arranges safety switch 3, connection is passed through in output and the charging end 5 of storage battery 4, this charging end 5 is the charger interface of low-voltage electrical appliance, and align with supporting surface 6 in the position of this charging end 5.
This device is applicable to railway station, the public arena that the large noise of the flows of the people such as passenger station is large, during use, this device is arranged on the wall of noise close quarters, hemispheric sound collector is conducive to the sound source from multiple directions in reception environment, noise produces pressure to piezoelectric ceramic, its two ends are made to produce voltage difference, and then charge a battery, realize acoustic-electric conversion, during outside access low-voltage electrical appliance, storage battery charges to electrical appliance, the public is facilitated to supplement the electricity of the low-voltage electrical appliance carried with in time, for life & amusement etc. offers convenience, finally realize effective utilization of noise.In order to protect storage battery not damaged because of overvoltage, add safety switch in circuit, when not having external charger and accumulator electric-quantity is full of, safety switch automatically disconnects thus cuts off circuit, and piezoelectric ceramic no longer carries out acoustic-electric conversion.
