Abstract
A loudspeaker frame comprises a frame body and the bottom of the frame body is fixedly connected with a clamp plate. The loudspeaker frame is characterized in that a plurality of radiating long slots are formed on the contact surface between the bottom of the frame body and the clamp plate; a plurality of strip-shaped radiating slotted holes are formed along the outer side of the frame body at the periphery of the bottom of the frame body; the bottom the frame body is opened; and a through-hole for a voice coil to pass through is formed at the center of the bottom of the frame body. The loudspeaker frame guarantees better contra-flow effect of the entire magnetic circuit system, and facilitates quick cooling down of the entire magnetic circuit system. The loudspeaker frame has a simple structure, is convenient for production, does not affect transmission effect, has high frame strength, and is stable. Compared with a conventional loudspeaker made of aluminum frame, the magnetic circuit system temperature is lowered by 20 to 30 DEG C under larger power and in long time, the service life is greatly prolonged, no cost increase is caused, and the energy-saving and emission reducing concepts are fulfilled.
Description
Technical field
The utility model relates to a kind of basin frame of loud speaker, especially a kind of speaker frame with better heat dissipation effect.
Background technology
Dynamic speaker is under the effect of permanent magnet, and the voice coil loudspeaker voice coil that enamelled wire centers on is after the audio signal input, and lower piston moves in the generation.Particularly supersound projector is working long hours down, and the heat energy that voice coil loudspeaker voice coil produces reaches more than 150 ℃, and T iron, magnet steel, clamping plate also can reach more than 100 ℃, will reduce the various performances of loud speaker like this, and serious also can burn out voice coil loudspeaker voice coil.
For overcoming the above problems, what cost was minimum, effect is best is exactly to make voice coil loudspeaker voice coil that better heat-dissipating space be arranged.Existing method is exactly, and the stable hole of T, voice coil loudspeaker voice coil punching, the punching of complex tone basin and the punching of basin frame produce effect but be not the most desirable.
The existing patent No. is the Chinese patent " being provided with the speaker frame of louvre " of CN200720043406.3, the bottom of basin frame is to lower recess, form concave station, both sides at basin frame long axis direction are provided with the terminal block installing hole, concave station is provided with the riveted joint installing hole, it is characterized in that: also be provided with louvre on concave station.It is to solve heat dissipation problem by offering louvre in basin frame bottom, but the louvre of this structure is confined to the bottom margin of basin frame, also is not very desirable to the radiating effect of whole magnetic circuit system.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, long service life at the above-mentioned state of the art, under the prerequisite that guarantees conducting effect, has the speaker frame of great heat radiation effect.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of speaker frame, comprise the basin frame, fixedlying connected with clamping plate in the below, bottom of basin frame, it is characterized in that: offer a plurality of heat radiation elongated slots on the bottom of described basin frame and the contact-making surface of clamping plate.
As improvement, the bottom periphery of described basin frame offers the heat radiation slotted eye of a plurality of bar shapeds along the basin frame outside.
As improvement, described heat radiation elongated slot is heat radiation sheet star arrangement, is uniformly distributed in the outer ring of basin frame bottom along basin frame bottom periphery.
Improve, described heat radiation slotted eye is for being uniformly distributed in the lower position of basin frame sidepiece along basin frame bottom periphery again.
Improve, the bottom of described basin frame is Open architecture again, and the center of basin frame bottom offers the through hole that can supply voice coil loudspeaker voice coil to place.
At last, described heat radiation elongated slot becomes corresponding distribution with the heat radiation slotted eye in the outside of basin frame, and interconnects.
Compared with prior art, advantage of the present utility model is: the bottom of basin frame is Open architecture, and offer a plurality of radiating grooves at the bottom and the sidepiece of basin frame, make that the hot and cold air exchange is frequent, clamping plate have the more long-pending contact of multiaspect air-flow, make the interior heat of voice coil loudspeaker voice coil along with air-flow is taken out of simultaneously, guaranteed that so whole magnetic circuit system has convection effects preferably, is beneficial to the fast cooling of whole magnetic circuit system.The utility model is simple in structure, easily manufactured, do not influence conducting effect, and basin frame intensity height, stable, the loud speaker that manufactures than traditional aluminium basin frame, high-power, descend the magnetic circuit system temperature can reduce 20-30 ℃ for a long time, increased useful life greatly, and cost free increases, meet the energy-saving and emission-reduction theory, be worthy to be popularized.
