Abstract
The utility model relates to an automatic on/off device, in particular to an automatic on/off device installed in an upper cover of a sound device. The automatic on/off device is arranged in the upper cover of the uncovered sound device and comprises a sound device circuit module and a gravity switch connected to the sound device circuit module. With the adoption of the automatic on/off device, the on and off of the sound device can be realized only by opening or closing the cover, therefore, the automatic on/off device has a simple structure and convenience in operation, and the attractive exterior appearance of the sound device is also ensured.
Description
Technical field
The utility model relates to a kind of recloser, is specifically related to a kind of auto powering on/off apparatus that is installed in the sound equipment loam cake.
Background technology
Along with the raising of people's living standard, people also improve constantly for the requirement of audio-visual equipment.Therefore, the performance of stereo set and the people's attention that also has been subjected to attractive in appearance.In recent years, stereo set occurred covering, it covers at sound equipment usually and is provided with switch, need be behind the lid that closes during the switch sound equipment powered-down again, not only influenced the attractive in appearance of equipment, and inconvenient operation.
The utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of sound equipment auto powering on/off apparatus of uncapping, and is used for the sound equipment of uncapping, and satisfies the purpose that realizes the switch sound equipment when the switch sound equipment covers.
For achieving the above object, the technical scheme that the utility model adopted is as follows:
A kind of sound equipment auto powering on/off apparatus of uncapping is arranged in the loam cake of the sound equipment of uncapping, and comprises the acoustics circuit module, is connected the gravity switch on the acoustics circuit module.
Described gravity switch comprises conductive box, first contact, second contact and conduction ball, one end of conductive box is provided with insulator cap, first contact is passed insulator cap and is extend in the conduction box body, and second contact directly is connected the other end of conductive box, and the conduction ball is arranged in conductive box.
Described conductive box is coated with dielectric film outward.
Conduction ball in the described gravity switch is a mercury ball.
The beneficial effects of the utility model are: the sound equipment auto powering on/off apparatus of uncapping of the present utility model only need be by uncapping and closing the Push And Release that lid just can be realized sound equipment.Therefore, the utility model is not only simple in structure, easy to operate, and has guaranteed the attractive in appearance of stereo set outside.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model sound equipment auto powering on/off apparatus structural representation of uncapping;
Fig. 2 is gravity switch off-state figure of the present utility model;
Fig. 3 is gravity switch closure state figure of the present utility model.
Embodiment
As shown in Figure 1, the sound equipment auto powering on/off apparatus of uncapping of the present utility model is arranged in the loam cake of the sound equipment of uncapping, and comprises the acoustics circuit module, is connected the gravity switch on the acoustics circuit module; Described conductive box is coated with dielectric film outward.
As shown in Figure 2, described gravity switch comprises conductive box 1, first contact 2, second contact 3 and conduction ball 4, one end of conductive box 1 is provided with insulator cap 5, first contact 2 is passed insulator cap 5 and is extend in the conductive box 1, second contact 3 directly is connected the other end of conductive box 1, and conduction ball 4 is arranged in conductive box 1.The box body that wherein conducts electricity is an electric conducting material, and the sound equipment auto powering on/off apparatus of uncapping of the present utility model is uncapped or closed when covering, because the effect of gravity is rolled the conduction ball in the gravity switch in gravity switch; Open when covering, the conduction ball of gravity switch 4 is stressed to be moved to first contact 2, and conduction ball 4 touches 2, the first contacts 2, first contact and is connected to second contact 3 by conduction ball 4 and conductive box 1, realizes being connected with acoustics circuit, and sound equipment is opened; Shut sound equipment when lid, ball 4 is stressed again moves to second contact 3 for conduction, first contact 2 with conduct electricity ball 4 and no longer be connected, circuit is disconnected, sound equipment is closed simultaneously.
In the utility model preferred version, described conduction ball available water ping-pong ball is replaced.Above-mentioned execution mode only is a preferred version of the present utility model; can not regard the restriction to the utility model protection range as, those skilled in the art makes the change of any unsubstantiality or replaces and all belongs to protection range of the present utility model on basis of the present utility model.
