Can, the magnetic circuit system of the speaker unit of the prior art uses multipath magnetic circuit structure, including centring magnet and is set around centring magnet
The side magnet set, centring magnet with while magnet close to vibrational system side be respectively arranged with center washer and while washer.Existing
Speaker unit production process in, while washer by glue paste with while magnet fix, in adhesion process, need by work
Installing is standby to be realized, process is relatively complicated, low production efficiency.Also, it is influenced by external environment, the bond properties of glue can be gradual
It reduces, keeps washer positioning in side insecure, reduce the reliability of speaker unit.
Therefore, it is necessary to a kind of improvement be proposed, to overcome existing speaker unit defect.
Invention content
That technical problem to be solved by the invention is to provide a kind of production efficiencys is high, reliability is high, acoustical behavior is good raises
The manufacturing method of sound device device and its shell.
To achieve the goals above, the present invention uses following technical scheme：
A kind of speaker unit, including vibrational system, magnetic circuit system and auxiliary system, the auxiliary system include receiving
The shell and conduct piece of the fixed vibrational system and the magnetic circuit system, the magnetic circuit system include centring magnet and surround institute
The side magnet of centring magnet setting is stated, the centring magnet is provided with center washer, the side close to the vibrational system side
Magnet is provided with side washer close to the vibrational system side, and：The side washer is combined with the shell integrated injection molding, institute
Conduct piece is stated to be combined with the shell integrated injection molding.
As a kind of perferred technical scheme, the vibrational system includes voice coil, and the voice coil is provided with voice coil leads, institute
Voice coil leads are stated along the side washer fair line, the voice coil leads are electrically connected with the conduct piece.
As further preferred, the voice coil leads pass through fixing glue and are positioned with the side washer.
Meanwhile the manufacturing method of the shell of speaker unit of the invention：By the side washer with material-strap structure, conduct piece point
It is not fixed with injection forming mold；It is molded, shell, shell and side washer, conduct piece one is formed by injection molding process
It is body formed；It is cooling, after shell, side washer and the cooling of conduct piece integral structure, cut off the side washer material strip and conduct piece material strip.
The speaker unit of the present invention, side washer, conduct piece are combined with shell integrated injection molding, improve side washer, lead
The firmness that electric part is combined with shell improves the reliability of speaker unit, also, side washer, conduct piece and shell one
Injection molding combines, in speaker unit assembles production process, it is not necessary to which independent fixed edge washer and conduct piece again simplify production work
Sequence improves production efficiency；Side washer is combined with shell integrated injection molding, can be increased side washer area, is conducive to speaker unit
Magnetic circuit maximizes design, improves speaker unit acoustical behavior.Therefore, speaker unit of the invention have production efficiency it is high,
The advantage that reliability is high, acoustical behavior is good.
Description of the drawings
Fig. 1 is speaker unit shell mechanism of the present invention and voice coil combination schematic diagram；
Fig. 2 is speaker unit shell mechanism schematic diagram shown in Fig. 1；
Fig. 3 is speaker unit manufacturing process schematic diagram shown in Fig. 1.
Specific implementation mode
Below in conjunction with the accompanying drawings, content that the present invention will be described in detail：
Speaker unit of the present invention, it is similar with traditional structure speaker unit, including vibrational system, magnetic circuit system and auxiliary
System, auxiliary system include the shell of the fixed vibrational system of receiving and magnetic circuit system and by speaker unit and external circuit electricity
The conduct piece of connection, vibrational system include vibrating diaphragm and voice coil；Magnetic circuit system includes centring magnet, around the side that centring magnet is arranged
Magnet, centring magnet with while magnet close to vibrational system side be respectively arranged with center washer with while washer, centring magnet, center
Washer and while magnet, while washer between be provided with magnetic gap, vibrational system voice coil is set in magnetic gap, speaker unit work
When, foreign current enters voice coil, is set to the voice coil in magnetic gap by Lorentz force action up-down vibration, drives diaphragm oscillations
Sounding.
As shown in Figures 1 and 2, speaker unit side of the present invention washer 2 and conduct piece 3 are wholely set with shell 1.Bian Hua
Department 2, conduct piece 3 and shell 1 are combined by integrated through injection molding, improve side washer 2, the secured journey that conduct piece 3 is combined with shell 1
Degree, improves the reliability of speaker unit, also, side washer 2, conduct piece 3 are combined with 1 integrated injection molding of shell, is filled in loud speaker
It sets in assembling production process, it is not necessary to which the assembling for individually carrying out side washer 2, conduct piece 3 again is fixed, and the production of speaker unit is simplified
Process improves production efficiency；Side washer 2 is combined with 1 integrated injection molding of shell, can increase the area of side washer 2, is conducive to raise one's voice
Device device magnetic circuit maximizes design, improves speaker unit acoustical behavior.It is to be understood that speaker unit shown in attached drawing is only this
One specific implementation case of invention speaker unit, in practical application, side washer 2 can as shown be two-part structure
