Further, a kind of loud speaker that the utility model embodiment provides comprises: electromagnetic induction module, and the oscillating plate that links to each other with described electromagnetic induction module, the magnetic strain metal shell that links to each other with described oscillating plate, wherein:
Described electromagnetic induction module is for generation of electric current;
Described oscillating plate produces vibration under the driving of the electric current that described electromagnetic induction module produces;
Described magnetic strain metal shell vibrates along with the vibration of described oscillating plate, and then produces electric current.
Further, the utility model embodiment provides a kind of terminal, and it comprises battery and the described described loud speaker of the utility model embodiment, and described battery links to each other with the magnetic strain metal shell of loud speaker.
The utility model embodiment provides a kind of brand-new loudspeaker vibration device, this vibrating device also has the magnetic strain metal shell except having oscillating plate, described magnetic strain metal shell just can produce electric power under vibration, therefore, the vibrational energy that the utility model embodiment just can make vibrating device produce is converted into electric energy efficiently, like this, when the terminal of the utility model embodiment links to each other battery with the magnetic strain metal shell of loud speaker, just the electric energy that can produce by described magnetic strain metal shell is described powered battery, thus, realize the function of terminal self-charging.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is that the structure of an embodiment of loud speaker of the present utility model is formed schematic diagram.
Fig. 2 is that the structure of an embodiment of terminal of the present utility model is formed schematic diagram.
Fig. 3 is that loud speaker of the present utility model is given battery powered circuit connection diagram.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with accompanying drawing the utility model embodiment is further specified.
Fig. 1 is that a structure of the loud speaker of the utility model embodiment is formed schematic diagram.As shown in Figure 1, the loud speaker of the utility model embodiment can comprise electromagnetic induction module 11, oscillating plate 12 and magnetic strain metal shell 13, concrete, described oscillating plate 12 links to each other with described electromagnetic induction module 11, described magnetic strain metal shell 13 links to each other with described oscillating plate, wherein, oscillating plate 12 and magnetic strain metal shell 13 can constitute the vibrating device of the utility model embodiment.Like this, the electric current that produces when the electromagnetic induction module 11 of the loud speaker of the utility model embodiment drives oscillating plate 12 vibrations, and then drives described magnetic strain metal shell and vibrate at 13 o'clock, and described magnetic strain metal shell 13 just can produce electric current.As a kind of possible implementation, the oscillating plate 12 of the utility model embodiment and/or described magnetic strain metal shell 13 can be made by novel ferrocobalt material.Preferable, being the surface area that increases magnetic strain metal shell 13 and the electric energy that increases generation, described magnetic strain metal shell 13 can be centered around described oscillating plate 11 and described electromagnetic induction module 11 outsides.
Fig. 2 is that a structure of the terminal of the utility model embodiment is formed schematic diagram.As shown in Figure 2, the terminal of the utility model embodiment can comprise loud speaker 10 and battery 20, and wherein, described loud speaker 10 can be structure shown in Figure 1.Concrete, described battery 20 links to each other with the magnetic strain metal shell of described loud speaker 10.Please also refer to circuit connection diagram shown in Figure 3.As shown in Figure 3, when battery 20 links to each other with the magnetic strain metal shell 13 of loud speaker, then when magnetic strain metal shell 13 vibrations of described loud speaker, just can be to described powered battery.As a kind of possibility, between magnetic strain metal shell 13 and battery 20, be connected a unidirectional conducting diode D1, the effect of D1 is to prevent that electric current from flowing back to magnetic strain metal shell 13 from battery 20.Further, still with reference to figure 3, as a kind of possibility, be connected a K switch 1 between magnetic strain metal shell 12 and battery 20, the effect of K switch 1 is can disconnect the path of the two when not needing by 20 chargings of 13 pairs of batteries of magnetic strain metal shell.
One of ordinary skill in the art will appreciate that all or part of flow process that realizes in above-described embodiment method, be to instruct relevant hardware to finish by computer program, described program can be stored in the computer read/write memory medium, this program can comprise the flow process as the embodiment of above-mentioned each side method when carrying out.Wherein, described storage medium can be magnetic disc, CD, read-only storage memory body (Read-Only Memory, ROM) or at random store memory body (Random Access Memory, RAM) etc.
Above disclosed only is the utility model preferred embodiment, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of doing according to the utility model claim still belongs to the scope that the utility model is contained.
