Utility model content
Technical problem to be solved in the utility model is, overcome the defect of prior art, the vibration generating device that provides a kind of vibrational energy that can utilize the loudspeaker on loudspeaker box device to generate electricity.
For solving the problems of the technologies described above, the utility model proposes a kind of for the vibration generating device on audio amplifier, it comprises voice box casing, housing is provided with loudspeaker, the rear of described loudspeaker is provided with the first casing spaced apart from each other and the second casing, the rear section of described loudspeaker is located in the first casing, described the first casing is communicated with the second casing by guide duct, the outside of described the second casing is provided with vibrating diaphragm, on described vibrating diaphragm, be connected with coil, the outside of described coil is provided with the permanent magnet being fixedly connected with the second casing, and described coil connects a power board by wire.
Adopt after said structure, when audio amplifier is play music, shake before and after loudspeaker just start, air in the first casing will start air inlet by guide duct and once give vent to anger, drive the air in the second casing to change, vibrating diaphragm on the second casing just starts vibrations, drive the coil vibrations on vibrating diaphragm, because permanent magnet is fixed on the second casing, therefore coil vibrations produce induced current, generate electricity, and by wire, are connected with power board, power board is direct current by induced current rectifying and wave-filtering, can be for the battery charging in audio amplifier.The utility model can utilize the loudspeaker on audio amplifier to shake to generate electricity for the battery charging in audio amplifier, and do not need vibrating device to be attached on loudspeaker, but pass through guide duct, utilize the vibration of air driven vibrating diaphragm, can not have influence on the sounding of loudspeaker, and energy-conservation and can make the operating time of audio amplifier extend 30%～50% or longer.
As preferably, the outside of described the second casing is provided with opening, described vibrating diaphragm is connected on this opening by flexure strip, block this opening and can vibrate with respect to the second casing, described coil is loop coil perpendicular to vibrating diaphragm setting, described permanent magnet is annular permanent magnet and is located at coil outside, and permanent magnet is fixed on the housing in the second casing by a ring support.Adopt this structure, vibrating diaphragm vibrates on the second casing can be more obvious, and adopt loop coil, and annular magnet, can cut to greatest extent the magnetic field that annular magnet produces, and generating efficiency is higher.
As improvement, describedly for the vibration generating device on audio amplifier, also comprise battery and audio amplifier control board, described battery is connected with sound equipment control board and power board.Adopt this structure, the vibration generating device on audio amplifier is connected with battery by power board, can also charge to battery.Increase the service time of audio amplifier battery.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model proposes a kind of for the vibration generating device on audio amplifier, it comprises voice box casing 1, housing 1 is provided with loudspeaker 2, the rear of described loudspeaker 2 is provided with the first casing 3 spaced apart from each other and the second casing 4, the rear section of described loudspeaker 2 is located in the first casing 3, described the first casing 3 is communicated with the second casing 4 by guide duct 5, the outside of described the second casing 4 is provided with vibrating diaphragm 6, on described vibrating diaphragm 6, be connected with coil 7, the outside of described coil 7 is provided with the permanent magnet 8 being fixedly connected with the second casing 4, and described coil 7 connects a power board 9 by wire.
In the present embodiment, loudspeaker are located on the first casing, the outside of loudspeaker is covered with guard, the second casing be directly arranged in the first casing after, separate with dividing plate with the first casing, dividing plate is provided with hole, guide duct is located at and in this hole, is communicated with the first casing and the second casing, the rear board of the second casing is provided with opening, opening part is established vibrating diaphragm, vibrating diaphragm is connected to opening part by flexure strip, and by this opening sealing, loop coil is located at the inner side of vibrating diaphragm, vibrating diaphragm porpoise can drive loop coil porpoise, permanent magnet is annular magnet, and be fixed in the second casing by fixed support 11, loop coil porpoise, with respect to permanent magnet, move, can produce induced current, the two ends of coil are connected with power board by wire, power board can carry out induced current rectifying and wave-filtering and become direct current output, described power board is prior art, therefore do not repeat.
Because described audio amplifier is to drive audio amplifier control board (also can be described as power board) to control loudspeaker by lithium battery to sound, therefore described power board is also connected with lithium battery, for to lithium cell charging.
In the utility model, the position of the second casing be not necessarily located at the first casing after, can be located at any position, as long as it is communicated with the first casing by guide duct.In the present embodiment, the opening of the second casing is circular, and circular effect is better, can certainly be square or other shapes, but as long as it is because the vibration of vibrating diaphragm shuttle belt moving winding is just within the application's protection range.
Coil is made as annular and permanent magnet is made as annular, is also because can process convenient and efficiency is higher, can certainly be made as square because as long as coil vibration cutting magnetic field will produce induced current.Coil and permanent magnet are that other shape is also within the application's protection range.
Adopt after said structure, when audio amplifier is play music, shake before and after loudspeaker just start, air in the first casing will start air inlet by guide duct and once give vent to anger, drive the air in the second casing to change, vibrating diaphragm on the second casing just starts vibrations, drive the coil vibrations on vibrating diaphragm, because permanent magnet is fixed on the second casing, therefore coil vibrations produce induced current, generate electricity, and by wire, are connected with power board, power board is direct current by induced current rectifying and wave-filtering, can be for the battery charging in audio amplifier.The utility model can utilize the loudspeaker on audio amplifier to shake to generate electricity for the battery charging in audio amplifier, energy-conservation, can make the operating time of audio amplifier extend 30%～50% or longer.
