The manufacturing process of knot.
[Detailed description of the invention]
Fig. 1 is the cross-sectional view of loudspeaker of the present invention.
[specific embodiment]
The invention will be further described with embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of loudspeaker comprising magnetic circuit system 40, the vibrational system equipped with vibrating diaphragm 10 and collecting post
The frame 30 of magnetic circuit system 40 and vibrational system is stated, the vibrating diaphragm is equipped with main part 11 and from the main part 11 to the basin
The fixed part 12 that the bending of frame 30 extends, the vibrational system 40 include magnetic sheet 43 and 42 He of magnet steel being sequentially placed on magnetic sheet 43
Pole piece 41, the receiving magnetic circuit system 40 and vibrational system that the frame 30 is equipped with side wall 31 and is surrounded by the side wall 31
Accommodating space, the upper surface 310 of the side wall 31 of the frame 30 is equipped with the annular groove 32 for going material to be formed, the vibrating diaphragm 10
The receiving of fixed part 12 is fixed in the annular groove 32.
Preferably, the vibrating diaphragm 10 is additionally provided with the bending part 13 extended from the bending of the end of the fixed part 12, the basin
Frame 30 is additionally provided with the limiting slot 33 extended from the annular groove 32 bending, and the limiting slot 33 connects with the annular groove 32
Logical, the receiving of bending part 13 is fixed in the limiting slot 33, thus, it is possible to reinforce the combination between vibrating diaphragm 10 and frame 30
Degree.In the present embodiment, the fixed part 12 and bending part 13 are formed as L-type, in other embodiments, the fixation
Portion and bending part can also be formed as T-type, i.e., the end of self-fixed department reversely bends and extends to form, as long as making bending part and basin
Frame forms position limiting structure, is all possible.
In the present invention, the vibrating diaphragm 10 and frame 30 are integrated injection moldings, and the vibrating diaphragm 10 uses liquid-state silicon rubber
Glue material.Silicon rubber vibrating diaphragm 10 has excellent heat resistance, and extensibility is big, and tensile strength is high and hardness is adjustable, thus uses
Silastic material.In addition, fluid silicone rubber has good fluidity, vulcanization is fast, is easy to the advantages that being molded, thus be easier to realize with
The injection molding of frame combines.
The present invention also provides the assembly method of a kind of vibrating diaphragm 10 of loudspeaker and frame 30, this method includes following step
It is rapid:
Step 1, provides a vibrating diaphragm molding die, and the fixed frame 30 fills silicon rubber in the vibrating diaphragm molding die
