Description

There is the Microspeaker of integrated shell fragment

Technical field

The utility model relates to a kind of Microspeaker.

Background technology

Microspeaker is that one is when passing to signal code, current signal is changed out the device of voice signal, direction, the back side schematic diagram as shown in Figures 1 and 2 of structure in the past of Microspeaker, shell fragment 2 ' is assemblied in the rear end of speaker frame 1 ', one end of shell fragment 2 ' is electrically connected with the voice coil leads (not shown) of inside loudspeakers by terminal plate 3 ', terminal plate 3 ' is as the intermediate medium of voice coil leads, the other end of shell fragment 2 ' is then on elasticity conflict mobile phone circuit, the terminal plate 3 ' of existing loud speaker is injection-moulded in plastic part frame 1 ', shell fragment 2 ' and terminal plate 3 ' fix conducting by laser welding mode, make operation in the assembling process of loud speaker loaded down with trivial details, production efficiency is low, likely Laser Welding produces conducting extremely because rosin joint is bad, increase the bad probability of product, and adopt laser welding equipment to be welded and fixed, also the equipment cost that input ratio is higher is needed.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and reduces assembling product operation and cost is low, production efficiency the is high Microspeaker with integrated shell fragment.

For achieving the above object, the utility model is by the following technical solutions:

There is the Microspeaker of integrated shell fragment, comprise the frame in frame-type and be arranged on two shell fragments on the side frame rear end of described frame both sides respectively, described shell fragment is one-body molded connecting portion, fixed part and elastic portion, and described connecting portion extends to the front end of described frame from the side of described fixed part.

Described connecting portion comprises and down bends by the inside edge of described fixed part the sidewall extended, and the platen surface extended to form from described sidewall end toward horizontal direction.

Described fixed part be connected to described frame side frame on and the laminated structure fitted with the bottom shape of described side frame, described side frame is provided with protruding buckle, the head of described fixed part has the open slot for being stuck on described buckle, and the afterbody of described fixed part bends to arc.

Described elastic portion is the sheet being bent from the afterbody of described fixed part and extend toward the cephalad direction of fixed part, and the coupling part between described elastic portion and described fixed part is bent to form a not closed ring, and the end of described elastic portion forms the position-limit foot bent.

After adopting technique scheme, the utility model is compared with background technology, and tool has the following advantages:

1, the utility model is by integrated with terminal plate for haptic element shell fragment, and phase structure than ever, has saved the component costs of terminal plate, reduces material cost.

2, decrease the production process of product, decrease the operation of blowing when moulding is shaping, simple process, improve the production efficiency of product.

3, haptic element shell fragment is integrated with terminal plate, phase structure than ever, avoids because Laser Welding produces conducting extremely because rosin joint is bad, solves the technical problem of cumbersome, product quality difference, improve product reliability.

4, adopt fuse machine to fix parts, structure needs laser welding equipment to be welded and fixed as compared with the past, decreases the input of equipment cost.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment

As shown in Figure 3, there is the Microspeaker of integrated shell fragment, comprise the frame 1 in frame-type and be arranged on two shell fragments 2 on both sides, frame 1 rear end respectively.

Wherein frame 1 has the upper ledge 11, lower frame 12 and two side frames 13 that surround frame type, and wherein two side frames 13 are provided with protruding buckle 14 at the tip position near upper ledge 11.

As shown in figs. 4 and 5, shell fragment 2 has integrated connecting portion 23, fixed part 21 and elastic portion 22, wherein shell fragment 2 fixed part 21 for be connected to frame 1 side frame 13 on and the laminated structure fitted with the bottom shape of side frame 13, the head (namely towards one end of upper ledge 11) of fixed part 21 has the open slot 24 for being stuck on the buckle 14 of side frame 13, and the afterbody of fixed part 21 bends to arc.

The elastic portion 22 of shell fragment 2 is that the cephalad direction from the afterbody of fixed part 21 toward fixed part 21 bends the sheet of extending, and the coupling part between elastic portion 22 and fixed part 21 is bent to form an annular do not closed, and the end of elastic portion 22 forms the position-limit foot 25 of bending.

As shown in Figure 5, the connecting portion 23 of shell fragment 2 from the side of fixed part 21 before frame 1 extreme direction extend and formed, be specially, the inside edge being positioned at head one end by fixed part 21 down bends the sidewall 26 extending a vertical direction, and forms a fan-shaped platen surface 27 at sidewall 26 end toward horizontal-extending.Sidewall 26 is bent to form the right angle of 90 degree with the fixed part 21 of sheet, and platen surface 27 and sidewall 26 are also bent to form the right angle of 90 degree, thus makes fixed part 21 and connecting portion 23 be formed stepped.

The shell fragment 2 of integration is fixed on the side frame 13 of frame 1 by hot melting way by the utility model, right angle between connecting portion 23 with fixed part 21 matches with side frame 13, the platen surface 27 of connecting portion 23 is positioned at frame 1 front end, it is directly electrically connected with inner voice coil leads, eliminate the terminal plate 3 be injection-moulded in frame housing, namely achieved the electrical connection of voice coil leads and loud speaker external circuit by shell fragment 2.

The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
