[embodiment]
Below in conjunction with accompanying drawing and execution mode the present invention is described further.
Vibrational system of the present invention is a kind of vibrational system that is used in the products such as minitype acoustic generator; The minitype acoustic generator of correlation technique comprises the basin frame; Be fixed on vibrational system and magnetic circuit system on the basin frame; Magnetic circuit system drives said vibrating system vibration, thereby accomplish electrical signal conversion is become mechanical oscillation and sounding sound.The invention provides four kinds of execution modes, specific as follows:
First kind of execution mode, shown in Fig. 1-3, a kind of vibrational system 10, it comprises vibrating diaphragm 1 and is fixed on to shake touches the voice coil loudspeaker voice coil 2 on 1.Vibrating diaphragm 1 comprises the first ring portion 12 at ball top 11 and fulcrum ball top 11, and voice coil loudspeaker voice coil 2 is fixed on the ball top 11.Wherein, vibrational system 10 also is provided with the fixedly second ring portion 3 that is hollow form of voice coil loudspeaker voice coil 2.Concrete; The second ring portion 3 is fixed on the end away from vibrating diaphragm 1 of voice coil loudspeaker voice coil 2; The vibrating diaphragm 1 and the second ring portion 3 have formed the dual-support structure that voice coil loudspeaker voice coil 2 is carried out fixed support, and this dual-support structure has avoided vibrational system 10 when work, unbalance vibration to take place largely, thereby has improved the stability of vibrational system 10; And can its power be done more greatly and also not stationary vibration can not take place, make the acoustical behavior of products such as mini-sound device of utilization vibrational system 10 of the present invention more excellent.
In this execution mode; The second ring portion 3 comprise depressed part 31 and by depressed part 31 two ends respectively to first fixed part 32 and second fixed part 33 that extend away from depressed part 31 directions bendings; First fixing 32 ones are fixedly linked with voice coil loudspeaker voice coil 2; Promptly first fixed part 32 is fixed on the end away from vibrating diaphragm 1 of voice coil loudspeaker voice coil 2, and second fixed part 33 is fixed on the basin frame of mini-sound device of utilization vibrational system 10 of the present invention (not shown).More excellent, depressed part 31 is to the direction depression away from vibrating diaphragm 1 in this execution mode.Depressed part 31 the vibration that can make vibrating diaphragm 1 that greater strength is arranged is set, even also actuating force is stronger.Certainly, depressed part 31 also is not limited only to the direction depression away from vibrating diaphragm 1, also is feasible to the direction depression near vibrating diaphragm 1, and its principle is all the same.In addition, in this execution mode, the so-called second ring portion 3 can also be flexible centring disk, and can the centring disk setting be had electric conductivity, receives external circuit thereby also can voice coil line 222 be drawn through centring disk, and this all is feasible.
Second kind of execution mode; As shown in Figure 4; Itself and first kind of execution mode are roughly the same, and different is: the second ring portion 3 is sheathed to be fixed on the outside of voice coil loudspeaker voice coil 2 and separated by a distance with vibrating diaphragm 1, concrete; The second ring portion 3 is set in the outside of voice coil loudspeaker voice coil 2, and its first fixed part 32 is fixedly linked with voice coil loudspeaker voice coil 2 and is separated by a distance with vibrating diaphragm 1.
The third execution mode; As shown in Figure 5; Itself and first kind of execution mode are roughly the same; Different is: voice coil loudspeaker voice coil 2 comprises speech coil framework 21 and is fixed on speech coil framework 21 outsides and is positioned at the end of voice coil line 22 away from vibrating diaphragm 1 around the voice coil line that is arranged on speech coil framework 21 outsides 22, the second ring portions 3.Concrete, also promptly, first fixed part 32 is fixedly linked with speech coil framework 21 outsides and is positioned at the end of voice coil line 22 away from vibrating diaphragm 1.
The 4th kind of execution mode; As shown in Figure 6; Itself and first kind of execution mode are roughly the same, and different is: voice coil loudspeaker voice coil 2 comprises speech coil framework 21 and is fixed on the end away from vibrating diaphragm 1 of speech coil framework 21 around voice coil line 22, the second ring portions 3 on the speech coil framework 21 of being arranged on.Concrete, also promptly, first fixed part 32 is fixed on the end away from vibrating diaphragm 1 of speech coil framework 21.
Compare with correlation technique; Its second ring portion of vibrational system of the present invention and vibrating diaphragm have formed the dual-support structure that supports voice coil loudspeaker voice coil; Stable equilibrium more when making the vibration of said vibrational system, its power also can be accomplished bigger, and then can improve the acoustical behavior of the product of utilization vibrational system of the present invention.
Above-described only is execution mode of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
