Abstract
The utility model relates to a heat radiation structure of a thin type loudspeaker cavity. The heat radiation structure comprises a loudspeaker body and a loudspeaker cavity for placing the loudspeaker body. The loudspeaker cavity includes an upper cover that is used for fixing the loudspeaker body as well as a lower cover that is cooperated with the upper cover. Besides, a radiation fin is arranged between the loudspeaker body and the lower cover. According to the utility model, because of the utilization of the radiation fin, heat emitted by the loudspeaker body can be dissipated well, so that the lower cover is not damaged due to the high temperature. Moreover, the gap between the loudspeaker body and the lower cover can be substantially reduced; and the production cost can be reduced and the requirement of the thin type loudspeaker can be met.
Description
Technical field
the utility model relates to the loud speaker field, particularly a kind of thin speaker cavity heat radiation structure.
Background technology
General loud speaker all is installed in the cavity and works; Because present loud speaker slimming trend, it is more and more thinner that present loud speaker and speaker chamber are designed, but loud speaker generates heat when work easily; Sheet is the main thermal source of loud speaker heating under the loud speaker; Long-time heat accumulation can't distribute and just scorch the cavity lower cover easily, thus in design cavity process, all can consider how to dispel the heat, so can adopt two kinds of methods in the conventional design:
1. widen the gap between sheet under the loud speaker and the cavity lower cover; The thermal source that is produced when making speaker operation can be by the carried away by air movement in the cavity; Avoid cavity lower cover thermal source single-point to concentrate, cause temperature to surpass the temperature that cavity material can be born, this measure promptly causes the space between the cavity upper and lower cover to become big; Cause product thickness bigger, can't reach slim shape design object.
are selected the cavity material that can bear higher temperature for use under the design premises of slimming, but this measure meeting improves material cost greatly.
Summary of the invention
The purpose of
the utility model provides and a kind ofly can either satisfy loud speaker heat radiation and can make speaker chamber satisfy the cavity heat radiation structure of slimming design again.
are for achieving the above object; The technical scheme that the utility model adopts is: a kind of thin speaker cavity heat radiation structure; Comprise the loud speaker body, be used to be provided with the speaker chamber of described loud speaker body; Described speaker chamber comprise the loam cake that is used for fixing described loud speaker body, with the lower cover that described loam cake matches, it is characterized in that: be provided with fin between described loud speaker body and the described lower cover.
preferably, described fin adopts aluminium foil.
are because the technique scheme utilization; The utility model compared with prior art has advantage: because the utility model has adopted fin; The heat that makes the loud speaker body sent can be good at being distributed, and unlikely the mistake because of temperature is higher than the damage lower cover, and the utility model can reduce the gap between loud speaker body and the lower cover significantly; Reduce production costs simultaneously, satisfy the needs of thin speaker.
Description of drawings
accompanying drawing 1 is the cross-sectional schematic of the utility model.
In
above accompanying drawing: 1, loud speaker body; 2, loam cake; 3, lower cover; 4, fin.
Embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described:
embodiment one: shown in accompanying drawing 1; A kind of thin speaker cavity heat radiation structure; Comprise loud speaker body 1, be used to be provided with the speaker chamber of described loud speaker body; Described speaker chamber comprise the loam cake 2 that is used for fixing described loud speaker body, with the lower cover 3 that described loam cake 1 matches, be provided with fin 4 between described loud speaker body 1 and the described lower cover 3, described fin 4 is processed for aluminium foil.
are because the employing of fin 4; Can guarantee under the less situation in the gap between loud speaker body 1 and the lower cover 3 that the heat that loud speaker body 1 produces can well leave; Can not damage lower cover 3, thereby when producing thin speaker, save production cost.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection range of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the utility model
Claims (2)
1. thin speaker cavity heat radiation structure; Comprise the loud speaker body, be used to be provided with the speaker chamber of described loud speaker body; Described speaker chamber comprise the loam cake that is used for fixing described loud speaker body, with the lower cover that described loam cake matches, it is characterized in that: be provided with fin between described loud speaker body and the described lower cover.
2. a kind of thin speaker cavity heat radiation structure according to claim 1 is characterized in that: described fin is an aluminium foil.
