Wall portion 22 is corresponding with upper conduction magnetic board 4, and the side-walls of the upper conduction magnetic board 4 can form stronger magnetic induction region, make the side
Wall portion 22 it is firm in the shell 1 can be improved the metal net mask 2 by the larger adsorption of magnetic circuit system
Property.The application only limits the specific component of magnetic circuit system, and every scheme that can reach similar technology effect belongs to this Shen
Protection domain please.
Optionally, madial wall of the shell 1 on the inside of installation opening has scheduled pattern draft, makes the metal net mask
2 side of sidewall portion 22 can be more easily inserted into the shell 1.The pattern draft refers to installation opening from inside to outside slightly in opening
Inclined posture, demoulds after moulding convenient for shell.This pattern draft structure simultaneously can assemble metal net mask 2
Insertion installation operation at mouthful forms guiding function, and metal net mask 2 is enable more easily to cover and is located at installation opening, is not in
It is difficult to situation about being inserted into.Further, when side of sidewall portion 22 is inserted into close to the position of positioning table 11, the madial wall of shell is gradual
It shrinks, and good interference fit is formed with the side of sidewall portion 22, metal net mask 2 is formed to squeeze and is fixed.Optionally, it is described to pull out
Ranging from 0.5 ° -2 ° of mould gradient.
Optionally, the depth that the positioning table 11 extends internally from the installation opening is greater than or equal to the madial wall height
Half.The deeper positioning table 11 of setting, can make the side of sidewall portion 22 be inserted into deeper position in shell 1, can
It is more stabilized in the shell 1.Meanwhile the side of sidewall portion 22 can fully inhale it by from the magnetic circuit system
Attached effect is further stabilized in the shell 1.The depth that the application extends internally to the positioning table 11 from the installation opening
Degree is not limited, and those skilled in the art can be configured as needed, every scheme that can reach similar technology effect, all
Belong to the protection domain of the application.
As shown in Figure 1, loud speaker further includes support unit 3, the support unit 3 is arranged in the shell 1, the magnetic
Road system and vibrational system are fixed in the support unit 3.The madial wall of the support unit 3 and the shell 1 it
Between there are fit-up gap, the fit-up gap for the side of sidewall portion 22 of the metal net mask 2 insertion.
Wherein, annular pad 31 is provided on the inner wall of the support unit 3, the magnetic circuit system includes magnetic conduction frame
6, step outer 61 is formed on the end face of the magnetic conduction frame 6.When the magnetic conduction frame 6 is installed in the shell 1, bottom
Portion end is abutted with the shell 1, and the step outer 61 of the other end is bonded to each other with the annular pad 31, is formed to described
Support unit 3 supports and fixes.Further, the vibration component includes vibrating diaphragm 7, and the outer edge of the vibrating diaphragm 7 is fixed
It is connected on the support unit 3.
As shown in Figure 1, the shell 1 is provided with boss with the 6 corresponding position of magnetic conduction frame, the boss is configured
It is fixed to be used for the magnetic conduction frame 6, the diameter less than 6 bottom of magnetic conduction frame of the diameter of the boss, makes described lead
The bottom corresponding with the magnetic gap of the magnetic circuit system of magnetic frame 6 is exposed, and the ventilative of predetermined quantity is offered in the bottom of exposing
Hole, the air hole connect the magnetic gap with the cavity of the shell 1 of 6 bottom periphery of magnetic conduction frame.The list
There are enough fit-up gaps, the cavity of the shell 1 between body support frame 3 and the madial wall to pass through the fit-up gap and institute
The periphery connection of metal net mask 2 is stated, and then realizes the magnetic gap of the magnetic circuit system and 2 peripheral air stream of metal net mask
