Description
[technical field]
The utility model relates to a kind of acoustical generator, specifically refers to a kind of acoustical generator of microminiaturization.
[background technology]
For the miniaturization, the multifunction that adapt to various stereo set and information communication device develop, the acoustical generator used in this kind equipment is in requisition for being more tending towards miniaturized, and it is compacter with coordinating of described other elements of acoustical generator periphery, particularly along with the lightening growth requirement of mobile phone, wherein used acoustical generator, not only require miniaturization, more require high tone quality and stereo etc.
The acoustical generator relevant to the utility model, its involving vibrations system, magnetic circuit system and accommodate the frame of described vibrational system and magnetic circuit system, the voice coil loudspeaker voice coil that described vibrational system comprises vibrating diaphragm and is connected with described vibrating diaphragm, the ring portion that described vibrating diaphragm comprises ball top and is connected with described ball top, described ring portion comprises the lower surface of close described magnetic circuit system and the upper surface relative with described lower surface, described ball top protrudes out to the direction away from described magnetic circuit system and is placed in the upper surface in described ring portion, described voice coil loudspeaker voice coil is connected with the lower surface in described ring portion.The acoustical generator of this kind of structure can make the whole height of acoustical generator a lot, is unfavorable for the miniaturization of acoustical generator; In addition, the voice coil loudspeaker voice coil aspect ratio of the acoustical generator of this structure is higher, is not easy the position and the winding displacement that regulate voice coil loudspeaker voice coil.
Therefore, be necessary to provide a kind of novel acoustical generator to solve the problems referred to above.
[utility model content]
The purpose of this utility model is to provide a kind of acoustical generator that can improve the performance of product.
The technical solution of the utility model is as follows: a kind of acoustical generator, its involving vibrations system, magnetic circuit system and accommodate the frame of described vibrational system and magnetic circuit system, the voice coil loudspeaker voice coil that described vibrational system comprises vibrating diaphragm and is connected with described vibrating diaphragm, the ring portion that described vibrating diaphragm comprises ball top and is connected with described ball top, described ring portion comprises the lower surface of close described magnetic circuit system and the upper surface relative with described lower surface, and described ball top is tabular and is connected with the lower surface in described ring portion.
Preferably, described voice coil loudspeaker voice coil is connected with described ball top.
Preferably, described ring portion comprises flat connecting portion, the depressed part that extends outward from described connecting portion and the fixed part extended outward from depressed part, and described ball top is connected with connecting portion completely.
Preferably, described ring portion comprises the loop connecting portion of hollow, the depressed part extended outward from described connecting portion and the fixed part extended outward from depressed part, and described ball top section is connected with described connecting portion.
Preferably, the depressed part in described ring portion caves in described magnetic circuit direction.
The beneficial effects of the utility model are: at least one in both described frame and upper cover is provided with the first block for limiting the displacement of acoustical generator monomer, described first link stopper is arranged in louver, because the first block area is little, thus louver can be made to do more, and then improve the acoustical behavior of product.

Fig. 2 is the cutaway view of Fig. 1 along A-A line;
Fig. 3 is the three-dimensional exploded view of the utility model acoustical generator.
[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, for acoustical generator 100 of the present utility model, its involving vibrations system, magnetic circuit system 30, accommodate described vibrational system and magnetic circuit system 30 frame 12, cover the upper cover 11 connecing described vibrational system and the conducting terminal 40 be connected with external circuit.
The voice coil loudspeaker voice coil 23 that described vibrational system comprises vibrating diaphragm 20 and is connected with described vibrating diaphragm 20, the pole piece 33 that magnetic circuit system 30 comprises the magnetic bowl 31 be fixed in frame, is placed in the magnet steel 32 of magnetic bowl 31 and depends on magnet steel 32, simultaneously, magnetic bowl 31 and form magnetic gap between magnet steel 32 and pole piece 33, voice coil loudspeaker voice coil 23 is suspended in magnetic gap, and after voice coil loudspeaker voice coil 23 is energized, voice coil loudspeaker voice coil 23 can vibrate under the effect in magnetic circuit system magnetic field, meanwhile, voice coil loudspeaker voice coil 23 drives vibrating diaphragm 20 together to vibrate.
In the present embodiment, the ring portion 21 that described vibrating diaphragm 20 comprises ball top 22 and is connected with described ball top 22, described ring portion 21 comprises the lower surface of close described magnetic circuit system 30 and the upper surface 210 relative with described lower surface, described ball top 22 is tabular and is connected with the lower surface in described ring portion 21, and described voice coil loudspeaker voice coil 23 is connected with described ball top 22.That is, described ball top 22 is placed in the below in described ring portion 21, between ring portion 21 and voice coil loudspeaker voice coil 23, can save the height of voice coil loudspeaker voice coil 23 thus, when voice coil loudspeaker voice coil 23 height is certain with upper space, more easily regulates position and the winding displacement of voice coil loudspeaker voice coil 23.In addition, compare protruding ball top, flat ball top 22 of the present utility model can reduce the whole height of acoustical generator 100, and flat ball top 22 also more easily produces and assembles, and can reduce production cost.Because voice coil loudspeaker voice coil 23 is directly connected with ball top 22, ball top 22 can be made to obtain larger actuating force, thus improve the high frequency performance of acoustical generator 100.
In addition, the depressed part 212 that described ring portion 21 comprises flat connecting portion 211, cave in magnetic circuit system 30 direction from described connecting portion 211 and the fixed part 213 extended outward from depressed part 212, connecting portion 211 is positioned at the center in ring portion 21, described ball top 22 is connected with connecting portion 211 completely, the orthographic projection at ball top 22 is positioned at the connecting portion 211 in ring portion 21 completely, ball top 22 and connecting portion 211 glue together fixing, and fixed part 213 is fixed in frame 12.Because depressed part 212 is to magnetic circuit system 30 direction depression, the height of acoustical generator 100 entirety can be reduced, make full use of the inner space of acoustical generator 100.In other embodiments, the connecting portion in described ring portion also can be the circulus of hollow, and the part at ball top is connected with connecting portion; In addition, ring portion also can protrude out to the direction away from described magnetic circuit system.
Above-described is only execution mode of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection range of the present utility model.
