The structure comprises a basin stand with a basin-shaped structure; a through hole is formed on the bottom of the basin stand; an annular part is formed around the through hole; the inner wall of the through hole is fixedly connected with the outer wall of the upper end of a back cover; the lower end of a gasket and the annular part are fixed; the circumference of an elastic wave and the upper end of the gasket are fixed; a neodymium iron boron magnet and a clamping plate are stacked in the center of the inner side of the bottom of the back cover from bottom to top; a voice coil is arranged around the periphery of the clamping plate; a dust cap is stuck at the opening of the upper end of the voice coil; the middle part of the outer wall of the voice coil is respectively and fixedly connected with the inner side of a voice basin and the inner side of the elastic wave from top to bottom; and the bottom of the back cover is provided with a plurality of openings corresponding to the positions between the neodymium iron boron magnet and the inner wall of the back cover.
Description
Technical field
The utility model relates to a kind of magnetic circuit of loudspeaker radiator structure, belongs to loud speaker parts technical field.
Background technology
The structure of loud speaker generally includes the basin frame that is the peviform structure, basin frame bottom inside is fixedlyed connected with the outside, back cover upper end, basin frame bottom inside circumference is fixed with packing ring, the upper end that plays ripple circumference and packing ring is fixed, the inboard center of back cover is laminated with neodymium iron boron magnetic body and clamping plate from bottom to top, be provided with voice coil loudspeaker voice coil around the clamping plate periphery, voice coil loudspeaker voice coil upper end open place is covering dust cover, fixedlys connected with bullet ripple inboard with the inboard of sound basin respectively from top to bottom in voice coil loudspeaker voice coil outer wall middle part.In this structure, there is a sealing magnetic gap that surrounds by basin frame, back cover, neodymium iron boron magnetic body, clamping plate, voice coil loudspeaker voice coil, bullet ripple and packing ring, air-flow in the loud speaker magnetic gap and extraneous air-flow can not convection current, thereby make loud speaker exist heat dispersion poor, load power is low, the shortcoming that bass effect is not good.
Summary of the invention
The utility model purpose is by in loud speaker back cover bottom opening, the air-flow and the extraneous air-flow that reach in the loud speaker magnetic gap produce convection current, thereby it is poor to reach solution loud speaker heat dispersion, but load power is low and the not good shortcoming of bass effect, has also avoided simultaneously considering that from other aspects cost can not increase more problem relatively.
Above-mentioned purpose of the present utility model solves by the following technical programs: it comprises the basin frame that is the peviform structure, basin frame bottom is formed with through hole, be formed with ring part around the through hole, described through-hole wall is fixedlyed connected with back cover upper end outer wall, packing ring lower end and ring part are fixed, the upper end that plays ripple circumference and packing ring is fixed, back cover bottom inside center is laminated with neodymium iron boron magnetic body and clamping plate from bottom to top, be provided with voice coil loudspeaker voice coil around the clamping plate periphery, voice coil loudspeaker voice coil upper end open place is covering dust cover, fixedly connected with bullet ripple inboard with the inboard of sound basin respectively from top to bottom in voice coil loudspeaker voice coil outer wall middle part, it is characterized in that: the bottom at back cover is provided with several perforates corresponding to the position between neodymium iron boron magnetic body and the back cover inwall.The utility model will make that air-flow and the extraneous air-flow in the loud speaker magnetic gap produces convection current by several perforates that is provided with on back cover, reduce the pressure in the product, thereby reach good performance of heat dissipation, improve the load power and the bass effect of loud speaker.
As preferably, the aperture of described perforate is less than the spacing distance of neodymium iron boron magnetic body and back cover inwall.
As preferably, the axis of described perforate be positioned at neodymium iron boron magnetic body and back cover inwall gap in the middle of the place.
As preferably, the quantity of described perforate is 6 and evenly distributes at interval and be provided with.
So the air-flow that the utlity model has in the magnetic gap produces convection current with extraneous air-flow, has reduced the pressure in the loud speaker, reaches good performance of heat dissipation, that has improved loud speaker bears power and bass effect, and the product cost of increase is few.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the elevational schematic view of the utility model structure among Fig. 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of utility model is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2, the bottom that is the basin frame 1 of peviform structure is formed with through hole, be formed with ring part around the through hole, through-hole wall is fixedlyed connected with back cover 2 upper end outer walls, the lower end and the ring part of packing ring 10 are fixed, the upper end that plays ripple 7 circumference and packing ring 10 is fixed, back cover 2 bottom inside centers are laminated with neodymium iron boron magnetic body 4 and clamping plate 5 from bottom to top, clamping plate 5 peripheries are around voice coil loudspeaker voice coil 6 is arranged, voice coil loudspeaker voice coil 6 upper end open places are covering dust cover 8, fixedly connected with the inboard and bullet ripple 7 inboards of sound basin 9 respectively from top to bottom in voice coil loudspeaker voice coil 6 outer walls middle part, the horizontally disposed ring part adhesion of the outside of sound basin 9 and basin frame 1, bottom at back cover 2, be axis promptly with place in the middle of neodymium iron boron magnetic body 4 and the back cover 2 inwall gaps, stamp 6 perforates 3 that even interval is provided with, the aperture of perforate 3 is slightly less than the spacing distance of neodymium iron boron magnetic body 4 and back cover 2 inwalls.
After stamping the perforate of even interval setting in the back cover bottom, air-flow in the loud speaker magnetic gap and extraneous air-flow produce convection current, have reduced the pressure in the loud speaker, reach good performance of heat dissipation, that has improved loud speaker bears power and bass effect, and the cost amplification of product is little.
