Abstract
The utility model relates to a heat radiation device of a loudspeaker. The heat radiation device is characterized in that the device comprises a plastic bracket, an annular groove is arranged in the plastic bracket, an annular magnetizer with a U-shaped section is arranged in the annular groove, and a metal clamping plate is arranged on the upper plane of the magnetizer. Due to the arrangement of the metal platform on the upper plane of the magnetizer, the heat radiation area of the magnetizer is increased, the heat radiation efficiency of the magnetizer is enhanced, and the plastic bracket is prevented from deformation due to overheat caused by heat accumulation.
Description
Technical field
The utility model relates to the loudspeaker apparatus field, particularly a kind of heat abstractor of loud speaker.
Background technology
Along with the development of LCD TV contour structures, the variation of internal structure.Require the variation of the installing hole direction position of loud speaker, traditional punching press retort stand can't meet installation requirements, so plastic injection piece support loud speaker starts a large amount of uses.Well meet the installation requirement of liquid crystal TV set.But existing TV loudspeaker requires inner magnetic structure, high sensitivity is high-power.Conventional plastic support and the injection moulding of magnetic circuit U iron, directly in one (as shown in Figure 1), produce heat larger during because of the inner magnetic structure speaker operation, volume is little, in high-power situation, can cause magnetic circuit of loudspeaker to come off, noiseless thereby loud speaker damages.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of heat abstractor of loudspeaker plastic support, and its purpose is to increase the heat dispersion of magnetic conduction device, guarantees the normal operation of loud speaker vibroseis.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of heat abstractor of loud speaker, it comprises a plastic rubber bracket, in described plastic rubber bracket, is provided with cannelure, the magnetic conductor that the cross section that is provided with an annular in described cannelure is U-shaped, the upper plane layout of described magnetic conductor has a metal splint.
Preferably, described magnetic conductor and metal platform are riveted into one.
Preferably, described metal splint is cold-rolled steel sheet.
Pass through technique scheme, the heat abstractor of a kind of loud speaker that the utility model provides, by the upper plane layout at magnetic conduction iron, metal platform is arranged, the radiating efficiency that increases the area of dissipation enhancing magnetic conduction iron of magnetic conduction iron prevents from causing the plastic rubber bracket overheating deforming because of heat accumulation.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described.
The structural representation that Fig. 1 is loud speaker in prior art;
Schematic diagram after the middle magnetic conductor that Fig. 2 is the utility model embodiment and metal splint riveted joint;
The structural representation that Fig. 3 is this practicality.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The present embodiment as shown in Figure 2 and Figure 3, a kind of heat abstractor of loud speaker, it comprises a plastic rubber bracket 1, in described plastic rubber bracket 1, is provided with cannelure, the magnetic conductor 2 that the cross section that is provided with an annular in described cannelure is U-shaped, the upper plane riveted joint of described magnetic conductor 2 has a cold-rolled steel sheet 3.
In the present embodiment, for avoiding using the plastic stent loud speaker to cause magnetic conductor 2 to come off at high-power use state because producing heat, increase a cold-rolled steel sheet 3, at clamping plate of port riveted of magnetic conductor, and then be injected on plastic stent, be designed with like this 2 advantages: 1, increase area of dissipation, 2. avoid magnetic circuit U iron directly directly to contact with plastic stent.Thereby the reliability of loud speaker while meeting high-power use, meet the requirement of client to power of loudspeaker.Because new structure has solved the heat dissipation problem of plastic stent loud speaker, improved the reliability of loud speaker, meet the requirement to power of available liquid crystal electroacoustic machine, in the immovable situation of overall dimension, improve the magnetic circuit of loudspeaker service efficiency.
The above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.Multiple modification to these embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (3)
