Abstract

The utility model discloses a loudspeaker. The loudspeaker comprises a loudspeaker frame, a main magnet arranged inside the frame, a diaphragm arranged above the main magnet, a voice coil frame arranged on the lower surface of the diaphragm and voice coil windings wound on the voice coil frame. The diaphragm comprises a diaphragm spherical top and a diaphragm edge. The edge part of the diaphragm spherical top extends downwards to form the voice coil frame. The diaphragm spherical top and the voice coil frame are integrally formed and connected. By arranging the voice coil frame and the diaphragm spherical top in an integrally formed way, the loudspeaker can effectively prevent the voice coil frame with a relatively instable cross section shape from being deformed under the effects of the voice coil windings. Meanwhile, the voice coil windings can be independently wound and then sleeved on the voice coil frame. Therefore, the size precision can be better controlled.

Description

A kind of loud speaker

Technical field

the utility model relates to the loud speaker field, particularly a kind of loud speaker.

Background technology

loud speaker is one of requisite article in life, it produces high-frequency vibration after mainly relying on voice coil loudspeaker voice coil coil electricity wherein under the effect in magnetic field, the voice coil loudspeaker voice coil coil passes to vibrating diaphragm by speech coil framework by vibrations, the vibrating diaphragm vibrations are sounded, general vibrating diaphragm comprises that vibrating diaphragm ball top and vibrating diaphragm edge two parts of one form, and general employing of speech coil framework such as pastes at the connection that mode is fixed on vibrating diaphragm ball top and vibrating diaphragm edge, but the manufacture craft restriction due to speech coil framework, as shown in Figure 3, wherein speech coil framework 3 sticks to the below on vibrating diaphragm ball top 1 by glue 6, because speech coil framework 3 materials are softer, it not again comparatively stable cylindrical shape, when voice coil loudspeaker voice coil is designed to rectangle that Aspect Ratio is larger or track type, under the effect of voice coil line, speech coil framework is easy to produce distortion (as shown in Figure 4, the speech coil framework distortion schematic diagram of one track type), affected calmly the use of loud speaker.

Summary of the invention

the purpose of this utility model is to provide the on-deformable loud speaker of a kind of speech coil framework.

for achieving the above object, the technical solution adopted in the utility model is: a kind of loud speaker, it comprises speaker frame, be arranged on main magnetic in described framework, be arranged on described main magnetic top vibrating diaphragm, be arranged on described vibrating diaphragm lower surface speech coil framework, be wrapped in the voice coil loudspeaker voice coil coil on described speech coil framework, described vibrating diaphragm comprises vibrating diaphragm ball top and vibrating diaphragm edge, described vibrating diaphragm ball top margin edge extends to form speech coil framework downwards, and described vibrating diaphragm ball top is connected with described speech coil framework is one-body molded.

preferably, the shape of cross section of described speech coil framework is identical with the shape of described vibrating diaphragm ball top edge.

further preferably, the cross section of described speech coil framework is track type, rectangle or ellipse.

preferably, the bottom of the described speech coil framework formation kink that stretches out.

further preferably, the bottom of described voice coil loudspeaker voice coil coil is leaned on mutually with described kink, and kink can hold the voice coil loudspeaker voice coil coil, prevents that it from gliding, thereby makes the length of speech coil framework shorten, and meets the design requirement of thin speaker.

because technique scheme is used, the utility model compared with prior art has following advantages:

because the utility model pushes up one-body molded setting by speech coil framework and vibrating diaphragm ball, can effectively prevent the comparatively unsettled speech coil framework of shape of cross section under the effect of voice coil loudspeaker voice coil coil and produce distortion, after the voice coil loudspeaker voice coil coil can wind separately simultaneously, cover is set on speech coil framework again, and dimensional accuracy can better be controlled.

The accompanying drawing explanation

the schematic diagram that accompanying drawing 1 is embodiment mono-;

the schematic diagram that accompanying drawing 2 is embodiment bis-;

the schematic diagram that accompanying drawing 3 is prior art;

accompanying drawing 4 is existing speech coil framework distortion schematic diagram.

in above accompanying drawing: 1, vibrating diaphragm ball top; 2, vibrating diaphragm edge; 3, speech coil framework; 4, voice coil loudspeaker voice coil coil; 5, kink; 6, glue.

Embodiment

below in conjunction with embodiment shown in the drawings, the utility model is further described:

embodiment mono-: shown in accompanying drawing 1, a kind of loud speaker, comprise speaker frame (not drawing in figure), be arranged on the main magnetic (not drawing in figure) in framework, be arranged on the vibrating diaphragm of main magnetic top, be arranged on the speech coil framework 3 of vibrating diaphragm lower surface, be wrapped in the voice coil loudspeaker voice coil coil 4 on speech coil framework 3, voice coil line adopts glue 6 fixing with speech coil framework 3, vibrating diaphragm comprises vibrating diaphragm ball top and vibrating diaphragm edge 2, vibrating diaphragm ball top margin edge extends to form speech coil framework 3 downwards, vibrating diaphragm ball top and the one-body molded manufacture of speech coil framework 3, the shape that the shape of cross section of speech coil framework 3 and vibrating diaphragm ball push up 1 edge is all rectangle, wherein vibrating diaphragm ball top can be that metal material is as aluminium with speech coil framework 3, titanium, stainless steel etc., it can be also the plastic material of high rigidity, to guarantee the requirement of high frequency electrical, avoided again the work long hours problem of rear dilatancy of voice coil loudspeaker voice coil.

it is 1 one-body molded that the present embodiment speech coil framework 3 and vibrating diaphragm ball push up, can effectively prevent the comparatively unsettled speech coil framework 3 of shape of cross section under the effect of voice coil loudspeaker voice coil coil 4 and produce distortion, after voice coil loudspeaker voice coil coil 4 can wind separately simultaneously, cover is set on speech coil framework 3 again, and dimensional accuracy can better be controlled.

embodiment bis-: shown in accompanying drawing 2, the technical scheme of the present embodiment and embodiment mono-are basic identical, and difference is that the bottom of speech coil framework 3 stretches out and forms annular kink 5.

the present embodiment is except the advantage with embodiment mono-, kink 5 can hold voice coil loudspeaker voice coil coil 4, prevents that it from gliding, thereby saved general speech coil framework 3, stays more than one section in vain below voice coil loudspeaker voice coil coil 4, thereby make the length of speech coil framework 3 shorten, meet the design requirement of thin speaker.

above-described embodiment is only explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
