Abstract
The utility model relates to a combination of a loudspeaker and a voice coil with improved structure capable of improving power resistance, which mainly form an L-shaped annular abutted part at the lower end of the center of a vibrating diaphragm. The utility model can be abutted to the outer side and the lower side of a voice coil by means of the L-shaped design of the abutted part. The voice coil and the vibrating diaphragm form a two-side stereo abutting combination state to reinforce the combination strength thereof. A dustproof cover is abutted to the back of the upper side of the voice coil, and then the vibrating diaphragm is fixed at a positioning part of a tray frame. The voice coil is sheathed at the space between a pole sheet and a low sheet of the tray frame, and a front cover is fixedly sheathed outside the positioning part of the tray frame finally to clamp the vibrating diaphragm. Consequently, the assembly of the combination of a loudspeaker and a voice coil with improved structure capable of improving power resistance is finished. Because the vibrating diaphragm and the voice coil adopt the combination mode of the L-shaped annular abutted part, the utility model has large abutted area. The two abutted surfaces are perpendicular to each other, so the combination strength of the vibrating diaphragm and the voice coil can be largely improved to cause that the vibrating diaphragm and the voice coil can not shed and generate failure due to the vibration.
