Abstract
The utility model discloses a magnetic conduction device of a loudspeaker. The magnetic conduction device of the loudspeaker comprises a plastic support, wherein the plastic support is internally provided with an annular groove, the annular groove is internally provided with an annular magnetic conduction iron, and an upper surface of the magnetic conduction iron is provided with a metal platform. According to the magnetic conduction device of the loudspeaker, the upper surface of the magnetic conduction iron is provided with the metal platform, a heat radiation area of the magnetic conduction iron and heat radiation efficiency of the magnetic conduction iron are both improved, so deformation of the plastic support caused by heating because of heat aggregation is prevented.
Description
Technical field
The utility model relates to the loudspeaker apparatus field, particularly a kind of magnetic conduction device of loud speaker.
Background technology
Along with the volume of loud speaker constantly dwindles, the magnetic conduction device in it is because its mounting structure special makes the metallic support of magnetic conduction device can't satisfy existing market demands.The loud speaker engineer is in order to satisfy above demand; adopt plastic rubber bracket through regular meeting; but heat resistance and the heat dispersion of plastic cement are relatively poor; when power of loudspeaker is big; owing to be subjected to the heat effects of the magnetic circuit of loudspeaker; can make the plastic rubber bracket of magnetic conduction device that deformation can take place, cause the loud speaker vibroseis can't operate as normal, finally cause product bad.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of magnetic conduction device of loud speaker, its objective is the heat dispersion that increases the magnetic conduction device, guarantees loud speaker vibroseis operate as normal.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of magnetic conduction device of loud speaker, it comprises a plastic rubber bracket, is provided with cannelure in the described plastic rubber bracket, is provided with the magnetic conduction iron of an annular in the described cannelure, the plane is provided with a metal platform on the described magnetic conduction iron.
Preferably, described magnetic conduction iron and metal platform are one-body molded.
Preferably, described metal platform is riveted on plane on the magnetic conduction iron.
Pass through technique scheme, the magnetic conduction device of a kind of loud speaker that the utility model provides, be provided with metal platform by plane on magnetic conduction iron, 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.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of the novel middle magnetic conduction iron of this enforcement.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
Present embodiment as shown in Figure 1, a kind of magnetic conduction device of loud speaker, it comprises a plastic rubber bracket 2, is provided with cannelure in the described plastic rubber bracket 2, be provided with the magnetic conduction iron 1 of an annular in the described cannelure, the last plane of described magnetic conduction iron 1 is provided with a metal platform.Described metal platform and magnetic conduction iron are one-body molded.
In the present embodiment, magnetic conduction iron has increased big metal flat on last plane on original basis, and this plane and magnetic conduction iron can be one-body molded, also can form with the metal material riveted of different-thickness.Its advantage is, this magnetic conduction iron and plastic rubber bracket bound fraction are to be finished by the platform at magnetic conduction iron top, so when speaker operation, having reduced plastic rubber bracket contacts with the direct of magnetic circuit system, reduced the transmission of heat, the area of dissipation that has increased magnetic conduction iron has simultaneously guaranteed the plastic rubber bracket loud speaker when work, is not subjected to the heat effects of the magnetic circuit of loudspeaker and deformation or thawing take place.
The magnetic conduction iron of relative traditional type, this magnetic conduction iron increases metal flat, strengthen its area of dissipation, radiating effect is more near metallic support, thereby make loud speaker when work, the heat that its magnetic circuit system produces can leave timely, has reduced the heat demagnetization of magnet steel, and the too high and risk that burns out of voice coil loudspeaker voice coil Yin Wendu.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
