Handle 302, cover board are arranged on the communication path between 301 top Hatch Opening of electrostatic electret plate 202 and ash-storing bin, the ash-storing bin
301 sides are fixed with support shaft 305, and 305 end of support shaft is fixed with idler wheel 304, is provided with cunning on the outside of the idler wheel 304
Rail 303 is provided with convex block 306 on the inside of the sliding rail 303；The support shaft 305 is threadedly secured to the ash-storing bin 301
On, the idler wheel 304 is fixed in the support shaft 305 by flat key；
It is provided with trigger switch on the sliding path of filling plate, the bottom for filling plate is connected to a flexible transition joint
One end, the other end of the flexibility transition joint are connected to the end of the cover board；The screen number of the mesh enclosure 201 is not less than
20, the electrostatic electret plate 202 is fixed by screws on the mesh enclosure 201
The embodiment increases cover board compared with first embodiment and fills hardened structure, is mainly realizing basic dust suction time
On the basis of receiving function, the dual dust-proof automatic switchover under speaker work and off position is realized, and be powered on
Placement has been collected the secondary of dust and has been drifted when state, and specific work process is as follows:
When speaker is in idle off working state, the micro-protrusions on the filling plate in outside are fastened on inside mesh enclosure one by one
In 201 sieve pore, prevents external dust and float into speaker；When needing to enter normal operating conditions, hand-held filling plate is simultaneously downward
Sliding fills the sieve pore on plate and mesh enclosure 201 so that the micro-protrusions on filling plate are skidded off from the sieve pore of mesh enclosure 201 at this time
It being mutually communicated, guarantees the normal sounding of speaker, touch trigger switchs in sliding process, so that speaker power supply opening, meanwhile, this is filled out
The slide downward for filling plate pushes flexible transition joint to move into speaker, so that flexible transition joint drives cover board inwardly to push,
The inside movement of the cover board, so that cover board blocks the access blocked between electrostatic electret plate 202 and 301 top Hatch Opening of ash-storing bin
Diameter, to ensure that, in the work of speaker normal power-up, originally having collected dust in ash-storing bin 301 will not be due to cabinet itself
Vibration or external wind influence it is secondary float in speaker, cause secondary pollution.It is hand-held to fill out in speaker power cut-off state
Plate and upward sliding are filled, so that the micro-protrusions on filling plate are fastened on again in the sieve pore of mesh enclosure 201, at this time on mesh enclosure 201
Sieve pore by protrusion block, in the sliding process touch trigger switch so that speaker power supply close, meanwhile, the filling plate
Upward sliding pushes flexible transition joint to move to outside cabinet, so that flexible transition joint drives cover board to pull out, the cover board
Move out so that cover board is far from the communication path between 301 top Hatch Opening of electrostatic electret plate 202 and ash-storing bin, to protect
It has demonstrate,proved after speaker power-off, the dust adsorbed on electrostatic electret plate 202 passes through communication path under the effect of gravity and falls in storage ash
In storehouse 301.
Therefore this can be designed so that when speaker is powered and works normally, when having dust to enter from sieve pore, by electrostatic electret
Plate 202 is adsorbed, and without other positions fallen in speaker, and will not be put due to speaker itself power amplifier and to be generated when work
Vibration brings the dust being initially positioned in ash-storing bin 301 to drift inside speaker again；After speaker power-off, automatically switch state
Cover board on ash-storing bin 301 covers state, so that dust normally fall ins ash-storing bin 301, and the sieve pore on mesh enclosure is blocked by protrusion,
Enter to prevent external dust, and due to powering off, the power amplifier in speaker does not work, the sieve pore without vibration source, and on mesh enclosure
Blocked by protrusion, therefore cover board will not occur the secondary of dust in the ash-storing bin 301 and float far from 301 upper end of ash-storing bin at this time
It dissipates.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
