The working principle of all the above embodiments is as follows:
the initial state is as follows: the plugging plate 404 is located at the outermost end of the auxiliary inner groove 403, that is, the plugging plate 404 is far away from the electromagnet 408 disposed in the middle of the auxiliary inner groove 403, the reset spring 406 is not compressed, the driving gear 510 is not rotated, the winding rod 505 is not rotated, the chemical fiber cloth 506 is not released from the winding of the winding rod 505, and the first magnet 508 and the second magnet 509 are adsorbed.
The method comprises the following steps:
the working process of the temperature raising and equalizing component is as follows:
in use, when the sound box is used, the circuit in the auxiliary plate 2 generates heat, at this time, the mini-pump 401 pumps the heat in the circuit bin 201 under the action of the external control system, the pumped hot air enters the channel 402, further, as shown in fig. 3 and 5, with the pumping of the air, the gradually increased hot air in the channel 402 pushes the plugging plate 404 towards the direction close to the fixing plate 407, at this time, the return spring 406 is compressed, the vent 405 originally plugged by the inner wall of the sound box housing 1 is exposed, at the same time, the external control system controls the electromagnet 408 to energize to generate magnetism, at this time, the plugging plate 404 made of metal material is adsorbed by the electromagnet 408 and does not move any more, as shown in fig. 5, at this time, the hot air in the channel 402 moves through the vent 405 and towards the next plugging plate 404, further, when the small suction pump 401 sucks the second blocking plate 404 just contacted with the channel 402, the gas is insufficient to push the second blocking plate 404, at this time, the sucked hot gas is accumulated in the channel 402 outside the second blocking plate 404, that is, the hot gas only accounts for half of the acoustic shell 1, further, as the gas is further sucked from the line bin 201, the second blocking plate 404 is pushed, so as to move to release the blocking state of the air vent 405, at this time, the external control system controls the second electromagnet 408 to be electrified to generate magnetism, at this time, the sucked hot gas circulates in the channel 402 through the air vents 405 on the two blocking plates 404, further, the circulated hot gas finally flows out of the channel 402 on the acoustic shell 1 through the inclined slots 409, further, after a period of time, the external control system can cause the electromagnet 408 to be powered off and not have magnetism any more, at the moment, the compressed reset spring 406 can push the electromagnet 408 back to the initial state, and the next gas storage and release action is carried out along with the suction of the small-sized suction pump 401, so that the hot gas generated by the line in the line bin 201 is uniformly dispersed in the channel 402, the humidity around the sound shell 1 is reduced, namely, the situation that dust in the air is easily attached to the diaphragm bowl 3 in some wet areas or when the indoor humidity is high can be avoided through the arrangement of the temperature raising and equalizing component, and the situation that the sound quality of sound is damaged is avoided;
furthermore, when the temperature raising and equalizing component sucks hot air in the circuit bin 201 through the small air suction pump 401 to contribute to reducing the humidity around the sound box shell 1, the hot air in the circuit bin 201 is reduced, that is, the heat in the circuit bin 201 is reduced, and the arrangement can effectively avoid the situation that the skin of the sound box is aged due to heat of the circuit in the use process, and the service life is influenced;
