[0008] By arranging the magnetic circuit assembly in the frame, the overall height of the whole loudspeaker can be effectively reduced, the occupied space of the loudspeaker can be reduced, and the installation of the loudspeaker is facilitated.

[0009] The positioning support sheet is fixed to the inside of the voice coil, the size of the positioning support sheet can be greatly reduced, the overall weight of the vibrating part of the loudspeaker, i.e., the voice coil and the positioning support sheet, is reduced, the product decibel is improved, the positioning support sheet can effectively prevent dust from entering the voice coil and can play a dust-blocking role, and the dust cap in the original loudspeaker structure is eliminated.

[0010] Meanwhile, the size of the positioning support sheet only changes with the size of the voice coil and is irrelevant to the frame, which facilitates the design and reduces the mold opening cost.

[0011] The utility model is further configured as follows: the support assembly includes a pillar fixed to the middle of the upper end of the T iron, and the middle of the positioning support piece is abutted against the pillar;

[0012] A pressure column is provided above the positioning support piece, and the pressure column is fixedly connected to the support column by a first screw;

[0013] The outer edge of the positioning support piece is fixed to the inner wall of the voice coil.

[0014] The positioning support piece is supported by the pillar, and the assembly work of the positioning support piece can be facilitated by the pressure column and the first screw, and the later replacement work of the positioning support piece can also be facilitated.

[0015] The utility model is further configured as follows: a lower step through hole is formed in the middle of the T iron, a second screw is sleeved in the lower step through hole, and the second screw is screwed on the pillar;

[0016] An upper step through hole is formed on the pressure column, and the first screw is placed in the upper step through hole.

[0017] By placing the second screw in the T iron and the first screw in the pressure column, the aesthetics of the entire speaker product can be improved and the overall height and weight of the entire speaker can be reduced.

[0018] The utility model is further configured as follows: the magnetic circuit assembly further includes a magnet and a washer;

[0019] The lower end of the paper cone is fixed on the outer wall of the voice coil and the junction of the two is located above the washer.

[0020] The positioning support piece is an annular elastic piece with a wavy cross section;

[0021] A clearance hole is formed in the middle of the positioning support piece.

[0022] The positioning support can support and reset the voice coil.

[0023] The outstanding effects of the utility model are:

[0024] Compared with the prior art, arranging the magnetic circuit assembly in the basin frame can effectively reduce the overall height of the entire speaker, reduce the space occupied by the speaker, and facilitate the installation of the speaker.

[0025] The positioning support can effectively prevent dust from entering the voice coil, and can play a role in dust blocking, eliminating the dust cap in the original speaker structure.

[0026] At the same time, the size of the positioning support only changes with the size of the voice coil and has nothing to do with the basin frame, which facilitates design and reduces mold opening costs. BRIEF DESCRIPTION OF THE DRAWINGS
