Described jolting plate 14 produces the thin-plate member of sound equipment during as its plate face vertical tremor, be fixed on the bottom surface sections of outer cover 12.
Described voice coil loudspeaker voice coil 16 is the structure with the drum winding around, goes up the coiling coil at winding pipe (not shown) usually, and the bottom of its bobbin is attached to above the jolting plate 14, is configured to described magnet 20 close.Splicing ear 13a, the 13b of the signal input part 13 by voice coil loudspeaker voice coil 16, to voice coil loudspeaker voice coil 16 input high-frequency signals, if in case imported high-frequency signal like this, then by with the interaction of described magnet 20, make jolting plate 14 vibrations and produce the sound equipment of ormal weight.
Described thin slice (foil) 18 has the flat part 18a of Rack, central part at its flat part 18a is formed with the upwards protuberance 18b of side direction projection, plays the effect of supporting described magnet 20, and, thin slice 18 is made of metal material, so that it can have certain magnetic.
Clip 22 as mentioned above, the one end be positioned over magnet 20 above, work to fixedly secure magnet 20, make its immotile effect, generally constitute by metal materials such as pure iron.
Described ring 24, the hard mode of inserting among the engagement groove 12b that transversely forms with the inboard at described outer cover 12 combines its edge with engagement groove 12b and is fixed, and covers above the side of described clip 22 being configured to.Described ring 24 plays the effect of insertion parts especially, make described clip 22 and below leave certain distance between the spring 28 that describes in detail.
On the other hand, be formed with the blade 13c that on center position, has specific length on the top of described outer cover 12, described spring 28 is inserted between described ring 24 and the top and described blade 13c and fixedly secures, thereby vibration body 30 can be carried out elasticity move about (vibrations) to prescribed direction.In addition, the central portion on described spring 28 is formed with through hole 28b, from through hole 28b connect the position to the edge by drawing, be formed with bullport 28a Rack, that have curve shape.
Described vibration body 30 is inserted in the through hole 28b of the mid portion that is formed at described spring 28 and is fixedly connected, the vibration body 30 of combination has the open sleeve-shaped in top and the bottom like this, top is by the head 32 of edge shape and prolong the main body 34 that forms from the downside of described head 32 with having levels and constitute, its main body 34 with the mode secure bond of hard insertion, disposes to leave certain distance with described magnet 20 in the through hole 28b of spring 28.
Described vibrations coil 26 is wrapped in the outer peripheral edges of the main body 34 of vibration body 30, form one, and splicing ear 13c, 13d by the signal input part 13 on the regulation position that is arranged on outer cover 12, added the low frequency signal of telecommunication, in case added such signal, then produce magnetic circuit, and the electromagnetic force of passing through to be produced shakes described vibration body 30 by interaction with magnet 20.
Shake above-mentioned vibration body 30 by this way, improve the mode that in the past shakes vibration body 30 by other drive unit, having simultaneously can be with the effect of vibrating loudspeaker microminiaturization.
On the other hand, the upside that is preferably in vibration body 30 is formed with the guard block 32 that is made of fiber materials such as nonwoven fabrics, covers the opening portion of outer cover 12.
Below, referring to figs. 1 through Fig. 3, describe action and and effect in detail about vibrating loudspeaker of the present utility model.
At first, if splicing ear 13a, 13b by stimulus part 13 add the signal of telecommunication to voice coil loudspeaker voice coil 16, i.e. high-frequency signal, then because the mutual electromagnetic power between voice coil loudspeaker voice coil 16 and magnet 20 and the vibrations coil 26, jolting plate 14 vibrations, thus produce sound equipment.
In addition, if splicing ear 13c, 13d by signal input part 13 are to vibrations coil 26 input electrical signals, promptly, low frequency signal, then owing to shake the electromagnetic force that produces between coil 26 and the magnet 20, the main body 34 of vibration body 30 direction is to the left and right moved about, thereby vibration body 30 integral body shake.
At this moment, vibrating loudspeaker of the present utility model is according to user's selection, when the terminating machine of mobile phone etc. is worked with vibrating mode, promptly, low-frequency current is input under the situation in the above-mentioned vibrations coil 26, cushion by the spring 28 that supports vibration body 30, reduce the variation of shock momentum, therefore can obtain the effect of stable output vibrant characteristic.On the other hand, the vibrations degree of above-mentioned vibration body 30 can be regulated by the suitable selection signal of telecommunication.
As mentioned above, describe embodiment of the present utility model in detail, but interest field of the present utility model is not limited to this, the scheme identical in fact with embodiment of the present utility model all belongs to interest field of the present utility model.
Can recognize by above-mentioned explanation, in vibrating loudspeaker of the present utility model, the parts of actual vibrations are to be made of lighter voice coil loudspeaker voice coil, vibrations coil and vibration body, therefore, under low driving voltage, also can make the vibration body vibrations easily, have the effect of the power consumption of saving in this vibration.
In addition, as mentioned above, produce member in light weight of vibrations, therefore have and when the user passes on correct vibrations, make it can hear the effect of high-quality sound.
When mobile phones etc. were worked with vibrating mode, low-frequency current was input under the situation of vibrations coil, is cushioned by the spring that supports vibration body, reduces the variation of shock momentum, therefore had the advantage that can stablize the output vibrant characteristic.
Therefore vibrating loudspeaker of the present utility model constitutes subminaturization, can seek to be applicable to more simply in the terminating machine of microminiature mobile phone etc. and the earphone etc.
