Vibrating power-generation element includes, vibrating diaphragm, voice coil loudspeaker voice coil and field circuit, and these devices are housed inside in a shell body, needed when using by
Shell body sticks to the surface in ambient vibration source, diaphragm oscillations is driven by ambient vibration source, so that the magnet on vibrating diaphragm both sides is past
Multiple motion produces electric current with voice coil loudspeaker voice coil cutting.This vibration generating device needs to stick to ambient vibration source surface, if being bonded at loudspeaker
On, the tonequality of loudspeaker certainly will be influenceed, it is impossible to be applied on loudspeaker box device, thus at present be badly in need of one kind can be by loudspeaker box device
Loudspeaker vibration generating device.
The content of the invention
The technical problems to be solved by the invention are that the defect for overcoming prior art can utilize sound there is provided one kind
The vibrational energy of loudspeaker on case apparatus is come the vibration generating device that generates electricity.
In order to solve the above technical problems, the present invention proposes a kind of vibration generating device on audio amplifier, it includes audio amplifier
Housing, housing is provided with loudspeaker, and the rear of the loudspeaker is provided with the first casing spaced apart from each other and the second casing, the loudspeaker
Rear portion is set up separately in the first casing, and first casing is connected by guide duct with the second casing, the outside of second casing
Provided with vibrating diaphragm, coil is connected with the vibrating diaphragm, the outside of the coil is provided with the permanent magnet being fixedly connected with the second casing, institute
State coil and one power board is connected by wire.
After said structure, when audio amplifier plays music, the air that loudspeaker are begun in front and rear shake, the first casing will
The outlet once of air inlet once is started by guide duct, drives the vibrating diaphragm on the air change in the second casing, the second casing just to open
Begin to shake, drive the coil vibrations on vibrating diaphragm, because permanent magnet is fixed on the second casing, therefore coil vibrations produce induced electricity
Stream, is generated electricity, is connected by wire with power board, and induced-current rectifying and wave-filtering is DC current by power board,
It is available for the battery in audio amplifier to charge.The present invention can be shaken using the loudspeaker on audio amplifier charges it to generate electricity for the battery in audio amplifier
With, and vibrating device need not be attached on loudspeaker, but by guide duct, utilize air driven diaphragm oscillations, Bu Huiying
The sounding to loudspeaker is rung, and saves and the working time of audio amplifier can be made to extend 30%~50% or longer.
Preferably, the outside of second casing is provided with opening, the vibrating diaphragm is connected in the opening by flexure strip,
Block the opening and can be vibrated relative to the second casing, the coil is loop coil and set perpendicular to vibrating diaphragm, the permanent magnetism
Iron is annular permanent magnet and is located on the outside of coil that permanent magnet is fixed on the housing in the second casing by a ring support.Adopt
This structure is used, vibrating diaphragm vibrates on the second casing can be more obvious, and uses loop coil, and annular magnet, can
The magnetic field that cutting annular magnet is produced to greatest extent, generating efficiency is higher.
As an improvement, the vibration generating device on audio amplifier also includes battery and audio amplifier control panel, the battery
It is connected with sound equipment control panel and power board.Using this structure, the vibration generating device on audio amplifier passes through power supply
Plate is connected with battery, can also be charged to battery.Increase the use time of audio amplifier battery.

Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
The present invention proposes a kind of vibration generating device on audio amplifier, and it includes voice box casing 1, and housing 1 is provided with loudspeaker
2, the rears of the loudspeaker 2 is provided with the casing 4 of the first casing 3 and second spaced apart from each other, and the rear portions of the loudspeaker 2 is set up separately the
In one casing 3, first casing 3 is connected by guide duct 5 with the second casing 4, and the outside of second casing 4 is provided with vibrating diaphragm
6, coil 7 is connected with the vibrating diaphragm 6, the outside of the coil 7 is provided with the permanent magnet 8 being fixedly connected with the second casing 4, described
Coil 7 connects a power board 9 by wire.
In the present embodiment, loudspeaker are located on the first casing, and guard is covered with the outside of loudspeaker, and the second casing is directly arranged in first
Behind casing, separated with the first casing with dividing plate, dividing plate is provided with hole, guide duct, which is located in the hole, connects the first casing and the
Two casings, the rear board of the second casing, which is provided with opening, opening, sets vibrating diaphragm, and vibrating diaphragm is connected at opening by flexure strip, and
The opening is sealed, vibration can drive vibration, permanent magnet before and after loop coil before and after loop coil is located at the inner side of vibrating diaphragm, vibrating diaphragm
For annular magnet, and it is fixed in the second casing, is vibrated before and after loop coil by fixed support 11, relative to permanent magnet fortune
It is dynamic, induced-current can be produced, the two ends of coil are connected by wire with power board, power board can be by induced-current
Rectifying and wave-filtering is carried out into direct current electricity output, the power board is prior art, therefore is not repeated.
Because the audio amplifier is to drive audio amplifier control panel (alternatively referred to as power board) control loudspeaker to send sound by lithium battery,
Therefore the power board is also connected with lithium battery, for lithium cell charging.
In the present invention, the position of the second casing is not necessarily located at behind the first casing, can be located at any position, as long as its
Connected by guide duct with the first casing.The opening of the second casing is circle in the present embodiment, and circular effect is more preferable, certainly
Can also be square or other shapes, but as long as its be due to diaphragm oscillations band moving winding vibrate just the application protection domain it
It is interior.
Coil is set to annular and permanent magnet is set to annular, more facilitates and more efficient also in that can process,
It can certainly be set to square, as long as because coil vibration cutting magnetic field will produce induced-current.Coil and permanent magnet are it
Its shape is also within the application protection domain.
After said structure, when audio amplifier plays music, the air that loudspeaker are begun in front and rear shake, the first casing will
The outlet once of air inlet once is started by guide duct, drives the vibrating diaphragm on the air change in the second casing, the second casing just to open
Begin to shake, drive the coil vibrations on vibrating diaphragm, because permanent magnet is fixed on the second casing, therefore coil vibrations produce induced electricity
Stream, is generated electricity, is connected by wire with power board, and induced-current rectifying and wave-filtering is DC current by power board,
It is available for the battery in audio amplifier to charge.The present invention can be shaken using the loudspeaker on audio amplifier charges it to generate electricity for the battery in audio amplifier
With energy-conservation can make the working time of audio amplifier extend 30%~50% or longer.
