Description

Polygonal externally-mounted magnetic conducting sheet Technical Field The utility model relates to the technical field of loudspeaker devices, in particular to a polygonal externally-mounted magnetic conductive sheet. Background The loudspeaker is widely applied to electronic products such as sound systems, televisions and the like, and most of the existing loudspeakers comprise T-irons, magnets, washer, voice coils, a basin frame and drum paper. The Chinese sauce is usually a flat-plate type Chinese sauce, which is also called a magnetic conduction sheet. The common magnetic conductive sheet is generally formed integrally, and needs to be replaced integrally if damaged later, and in addition, the thickness of the magnetic conductive sheet is generally larger, the cost is higher and the magnetic conductive sheet needs to be improved in order to ensure smaller sound distortion. Disclosure of utility model In order to solve at least one technical defect, the utility model provides the following technical scheme: The application discloses a polygonal external magnetic conducting sheet, which comprises a first split body and a second split body, wherein the cross section of the first split body is T-shaped, the longitudinal end of the first split body is provided with a through hole formed along the axial direction, the second split body comprises a ring body and convex parts protruding outwards from the peripheral wall of the ring body at intervals, the inner peripheral wall of the ring body is provided with outwards protruding fixing blocks at intervals, the peripheral wall of the longitudinal end of the first split body is provided with a fixing groove, the middle ring body of the second split body is sleeved on the longitudinal end of the first split body, the fixing blocks are embedded into the fixing groove, and the bottom surface of the middle ring body of the second split body is in butt joint with the transverse end of the first split body. In this scheme magnetic conductive sheet with first components of a whole that can function independently, second components of a whole that can function independently equipment shaping, wherein the second components of a whole that can function independently passes through the ring body cover on first components of a whole that can function independently is indulged to horizontal end butt support ring body in the first components of a whole that can function independently, it is fixed with first components of a whole that can function independently to make ring body in the second components of a whole that can function independently with fixed block embedding fixed slot, the bellying interval arrangement helps reducing weight, help reduce cost, first components of a whole that can function independently, second components of a whole that can function independently equipment structure can be changed corresponding part according to the demand in follow-up maintenance, and the second components of a whole that can function independently material that plays main support and fixed action can be selected according to the demand, help reduce cost. Further, the thickness of the ring body in the second split body is consistent with the height of the longitudinal end in the first split body, the outer diameter of the ring body in the second split body is larger than the diameter of the transverse end in the first split body, the structural strength is improved, and the size of the transverse end is limited, so that the weight is reduced. Further, the cross section of the fixing block is in a trapezoid shape, and of course, triangular, rectangular and other configurations can be adopted. Further, the fixing holes are formed in the protruding portions in the thickness direction, and the elastic wave and other mechanisms in the loudspeaker can be conveniently abutted through screws and the like. Further, the top surface of the protruding portion is provided with a groove, two ends of the groove extend to opposite side surfaces of the protruding portion, the bottom wall of the groove is provided with a fixing hole, and when the elastic wave is installed, the side of the elastic wave is inserted into the groove to be pre-positioned, and then the elastic wave can be fixed through the cooperation of screws and the like and the fixing hole.
