Ground understands the advantages of present disclosure and its each side.Below in an example, detailed description below is provided
Purpose is easy for becoming apparent from present disclosure thorough explanation rather than limitation of the present invention.
Embodiment 1
First embodiment
Referring to figs. 1 to Fig. 5, the present invention provides a kind of loud speaker, including：Frame 1；It is arranged at shaking for 1 lower section of frame
Film 2；And it is fixed on the stent 3 in frame 1.
Specifically, in frame 1 have to away from vibrating diaphragm 2 a lateral process side wall 12, wherein side wall 12 be arcuation, frame
1 material is metal, to ensure the structural strength of loud speaker；Frame 1 includes being arranged on the installation cavity 11 of its corner, in embodiment party
In formula, the quantity of the installation cavity 11 in frame 1 is two, is symmetricly set on two corners of frame 1, and the installation cavity 11
The direction of inside along upper table towards the lower surface of frame 1 of frame 1 is perforation.
There is the first step portion 31 to match with 11 shape of installation cavity, stent 3 is fixed on the installation of frame 1 on stent 3
In chamber 11, the material of the stent 3 is insulating materials, and specifically, the material of stent 3 is, for example, plastics.In addition, also have on stent 3
There is the second step portion 32 that height is higher than 4 first weld part 41 of pad, second step portion 32 is adjacent with side wall 12.In the present embodiment
In, second step portion 32 and the shape of side wall 12 match.In this configuration, second step portion 32 and side wall 12 are arcuation,
So that in assembling process, side wall 12 has more orientations to stent 3, so as to which stent 3 be facilitated to position.
Further, stent 3 includes pad 4, and 4 injection molding of pad is on stent 3.In the present embodiment, pad 4
Such as stainless steel substrates, which bendingly forms, the quantity of stent 3 and pad 4 be two and with installation cavity 11 correspondingly
It sets.
Specifically, pad 4 includes the first weld part 41, is connected from the connecting portion 43 of the first weld part 41 extension and with this
The second connected weld part 42 of portion 43, the first weld part 41 and the second weld part 42 positioned at the both sides of stent 3 and expose to respectively
Stent.Further, the first weld part 41 and the second weld part 42 are located at the both sides up and down of stent 3 respectively, wherein, the first weldering
Socket part 41 is located remotely from the one side of vibrating diaphragm 2, and the second weld part 42 is located at close to the one side of vibrating diaphragm 2；First weld part 41 and outside
Circuit is electrically connected, and the second weld part 42 is for the welding with the voice coil leads in loud speaker.
In addition, stent 3 further includes the fixing piece 5 that material is metal, there is spacing, the two between the fixing piece 5 and pad 4
Mutually insulated.In the present embodiment, fixing piece 5 is that stainless steel substrates are bent to form, which includes being located in stent 3
Bending part 51 and be connected with the bending part 51 and be welded on the 3rd weld part 52 in frame 1, wherein, bending part 51 is for example
By injection molding in stent 3, and welding manner of the 3rd weld part 52 such as being welded by laser is fixed on frame 1,
Stent 3 is stably placed in frame 1, therefore, the structure of loud speaker is more stablized, and improves loud speaker
Fall reliability.In addition, the bending part 51 further improves the bonding strength between fixing piece 5 and stent 3, thus stent 3
It can be more solidly fixed in frame 1.It should be noted that the invention is not limited thereto, fixing piece 5 can also integrally exist in injection molding
In stent 3.
In addition, in the present embodiment, a stent 3 corresponds to two fixing pieces 5, two fixing pieces 5 are located at stent 3 respectively
Both sides, specifically, (in the present embodiment, the cross-sectional shape of frame on two intersecting sides of the corner of frame
For rectangle).
In the present embodiment, since the first step portion 31 on stent 3 and the shape of installation cavity 11 match, so the
In a part of structure insertion installation cavity 11 in one stage portion 31, another part structure is resisted against the side of installation cavity 11.It is above-mentioned
Structure realizes the effect between stent 3 and frame 1 in assembling process with pre-determined bit, thereby ensures that stent 3 and frame 1
Between assembling process it is more smooth, therefore, the connection effect between stent 3 and frame 1 is more preferable.In addition, pad 4 passes through injection
It is molded on stent 3, the bending part 51 of fixing piece 5 is by injection molding on fixing piece 5 so that stent 3 can be more firm
It is fixed in frame 1.
In addition, being provided with second step portion 32 on stent 3, on the one hand cause the relative position between stent 3 and frame 1
Relation is more stable, in assembling process, has better pre-determined bit effect between stent 3 and frame 1.On the other hand, pad 4
The first weld part 41 be located at the one side of stent 3, it is necessary to be subjected in the first weld part 41, and second step portion 32
It sets so that the first weld part 41 on pad 4 and there is preferably isolation effect between the side wall 12 of frame 1, prevent from using
The short circuit problem generated in the process.
In addition, the present invention is by being provided with the stent 3 of insulation, using metal frame 1 to ensure loadspeaker structure intensity
On the premise of, on the one hand, there is good insulation effect between pad 4 and frame 1.On the other hand, pad 4 is in welding, no
Short circuit phenomenon easily occurs, and heat conduction is not easy between the first weld part 41 and the second weld part 42.In addition, stent 3 is being raised one's voice
Occupied space and weight proportion are all smaller in device, so as to ensure the compact-sized of loud speaker and relatively light quality.
Compared with prior art, the structure of loud speaker of the invention realizes the good insulation between pad and frame
Effect thus avoids the short circuit problem generated during use；The fastness of the connection between stent and frame is improved, by
This improves the structural stability of loud speaker；Improve loud speaker falls reliability.
Other embodiment
Difference lies in this second embodiment, fixing piece 5 is fixed on frame 1 by glue with first embodiment
On.
In addition, with first embodiment and second embodiment, difference lies in the third embodiment, in stent 3
Without fixing piece 5, stent 3 is directly fixed on by glue in frame 1.
Embodiment 2
The present invention also provides a kind of assembly method of the loud speaker for embodiment 1, which includes：
First pad is molded on stent, which is being fixed on installation cavity for example, by the bonding mode of glue etc.
It is interior；
Fixing piece is molded into together with pad on stent, in fixing piece electric welding to frame；
Wherein, the loud speaker to be assembled includes the frame that material is metal, and the peace for being arranged on its corner is included in the frame
It behave affectedly；Material is the stent of insulating materials, which is fixed in frame, and stent includes pad and is spaced apart with the pad
Fixing piece, pad include the first weld part, the connecting portion extended from first weld part and be connected with the connecting portion second
Weld part, the first weld part and the second weld part positioned at the both sides of stent and expose to the stent respectively；
Fixing piece include be located at stent in bending part and be connected with the bending part and be welded in frame the 3rd weldering
Socket part.
Compared with prior art, by above-mentioned assembly method, the good insulation effect between pad and frame is realized,
