Embodiment
Easily there is bias in the assembling for the vibrating diaphragm caused due to factors such as the outside dimension of vibrating diaphragm tolerance after cutting are large in prior art and shell, and adopting the ring of vibrating diaphragm to carry out making paper moulds the high problem of the technical scheme cost of location, to ensure that vibrating diaphragm and shell assemble concentric by arranging multiple location structure in the non-ring region of vibrating diaphragm for the utility model.
Concrete, the utility model embodiment provides a kind of vibrating diaphragm, comprises vibrating diaphragm central area, is arranged at the ring portion at edge, vibrating diaphragm central area and is connected for the fixed part of bonding shell with periphery, ring portion; Region outside ring portion arranges one or more location structure, for ensureing the concentric of vibrating diaphragm and shell fitted position.
Wherein, the region outside ring portion arranges one or more location structure and refers at the one or more location structure in vibrating diaphragm central area; Or, at fixed part, one or more location structure is set; Or, in vibrating diaphragm central area and fixed part, location structure is set simultaneously.Preferably, in the present embodiment, location structure is arranged on vibrating diaphragm central area.
The region of the present embodiment in advance outside the ring portion of vibrating diaphragm arranges one or more location structure, when the assembling of vibrating diaphragm and shell, assembled by the location structure in auxiliary mould and the non-ring region of vibrating diaphragm, and the precision of auxiliary mould can well control, thus more easily realize the concentric fits of vibrating diaphragm and shell.
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
As Fig. 1-a ~ Fig. 1-c jointly shown in, for vertical view and the cutaway view of the vibrating diaphragm perspective view in the present embodiment and this vibrating diaphragm, the vibrating diaphragm in the present embodiment comprises vibrating diaphragm central area 1, is arranged at the ring portion 2 at edge, vibrating diaphragm central area 1 and is connected for the fixed part 3 of bonding shell with periphery, ring portion 2.
Wherein, arrange location structure 4 in vibrating diaphragm central area 1, this location structure 4 is bulge-structure or sunk structure, illustrates the location structure into bulge-structure in Fig. 1-c.
It should be noted that, the location structure in the present embodiment also can be arranged on fixed part; Or, be arranged on vibrating diaphragm central area and fixed part simultaneously.Due to the regional extent relative narrower of fixed part, be not easy to arrange location structure.Therefore, location structure is preferably arranged on vibrating diaphragm central area by the present embodiment.
It should be noted that further, the vibrating diaphragm central area in Fig. 1-a ~ Fig. 1-c of the present embodiment is plane, and obviously, vibrating diaphragm central area of the present utility model also can be cambered surface.When vibrating diaphragm central area is plane, location structure is relatively without planar projections or the depression of the vibrating diaphragm central area of location structure; When vibrating diaphragm central area is cambered surface, location structure is raised or sunken relative to the tangent plane of this place's cambered surface.Wherein, the raised or sunken height of location structure 4 is greater than 0.01mm, is less than 1mm.
In one preferred version of the present embodiment, two or three location structures 4 are set in vibrating diaphragm central area 1.
When vibrating diaphragm central area 1 arranges two location structures 4, the central point of two relative vibrating diaphragm central areas 1 of location structure 4 is symmetric; The symmetrical assembly precision more easily realizing location structure and auxiliary mould.
When vibrating diaphragm central area 1 arranges three location structures 4, one of them location structure 4 is arranged on the center of vibrating diaphragm central area 1, the central point of the relative vibrating diaphragm central area 1 of two other location structure 4 is symmetric, as shown in Fig. 1-b, in figure, three location structures 4 are evenly distributed on vibrating diaphragm central area 1; Or three location structures 4 form leg-of-mutton three summits, the central point of vibrating diaphragm central area 1 is this leg-of-mutton center.Symmetrical or one-tenth stable triangle distribution more easily realizes the assembly precision of location structure and auxiliary mould.
In this preferred version, two or three location structures are set in vibrating diaphragm central area, make vibrating diaphragm can obtain good assembling, avoid location structure easily to cause assembly precision poor very little, and location structure too much easily caused the problem of location.
As shown in Figure 2, for having the stiffener Dome perspective view of clearance structure, vibrating diaphragm in above-described embodiment also comprises the stiffener Dome being arranged at vibrating diaphragm central area, when arranging location structure in vibrating diaphragm central area, arranges clearance structure at the position of the corresponding location structure of Dome.With reference to figure 2, when arranging three equally distributed location structures 4 in vibrating diaphragm central area 1, in the position of corresponding three location structures 4 of Dome 5, clearance structure 6 is set respectively.
In actual applications, for ensureing the adhesive strength of Dome and vibrating diaphragm central area, around location structure, gluing process is carried out.
It should be noted that, the location structure in the utility model technique scheme and ring integrally shaping, i.e. location structure straight forming in vibrating diaphragm forming process.
Of the present utility model one embodiment still provides a kind of loudspeaker monomer, involving vibrations system and magnetic circuit system.The vibrating diaphragm of above-mentioned vibrational system provides vibrating diaphragm for technique scheme.
The present embodiment arranges one or more location structure by the region outside the ring portion of vibrating diaphragm, realizes the concentric fits of vibrating diaphragm and shell, thus ensures the acoustical behavior of loudspeaker monomer.
In sum, the utility model embodiment discloses a kind of vibrating diaphragm and loudspeaker monomer, region in advance outside the ring portion of vibrating diaphragm arranges one or more location structure, when the assembling of vibrating diaphragm and shell, assembled by the location structure in auxiliary mould and the non-ring region of vibrating diaphragm, because the precision of auxiliary mould can well control, therefore the utility model more easily realizes the concentric fits of vibrating diaphragm and shell compared to prior art.
The foregoing is only preferred embodiment of the present utility model, be not intended to limit protection range of the present utility model.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., be all included in protection range of the present utility model.
