Abstract

The utility model relates to an improved heat radiating structure for miniature trumpet inlayed thin material space. Principally, a heat radiating guide plate is arranged on rear metal base of internal inlay type miniature trumpet in thin material space of thin electronic products such as notebook, PDA and LCD, thus the heated metal base can transmit thermal energy to the heat radiating guide plate so as to enlarge heat radiation area of the miniature trumpet, prevent high temperature air concentrating in the miniature trumpet, strengthen heat radiation efficiency of the miniature trumpet, reduce temperature of voice coil inside the miniature trumpet, prevent the voice coil being burnt under high temperature, promote stability of outputted power, avoid hot air concentrating around the miniature trumpet aside shell of electronic product and prevent the shell of thin electronic product burning in high temperature.

Description

Compact horn is set the radiator structure that improves of thin material space

Technical field

The utility model relates to the structure that a kind of compact horn improves heat radiation, refer in particular to a kind of compact horn and be embedded at the structure of improving heat radiation in mobile computer (NOTEBOOK), PDA(Personal Digital Assistant), the LCD thin material spaces such as (LCD), and then reach and prolong compact horn and increase the service life, and can avoid high temperature to burn the thin material shell.

Background technology

To shown in Figure 3, general thin type electronics and IT products such as mobile computer (NOTEBOOK), PDA(Personal Digital Assistant), LCD (LCD) etc. are then set compact horn in order to meet multimedia function in its thin material space according to Fig. 1.Yet set compact horn at present is the demand of asking high audio, be to require to promote its output power, to be required to set the compact horn output power be 2～3W with present, though can reach the demand of high audio, but actual working characteristics can improve by the invar number, produce the electric current height relatively, resistance value is also high, and cause whole compact horn to produce near temperature up to 80～120 ℃, therefore compact horn is embedded at long-term high-power output in the thin material space, heating temp can influence and cause burning of voice coil loudspeaker voice coil, serious even can't stand because of thin type electronics and IT products shell that long term high temperature impacts to cause to set and locate the situation that shell burns around the compact horn and take place, so in order to solve present mobile computer (NOTEBOOK), PDA(Personal Digital Assistant), setting the heat dissipation problem of compact horn in the LCD thin material spaces such as (LCD), is the technical bottleneck that present this industry is faced.

Summary of the invention

The purpose of this utility model is based on the thin type electronics and IT products are set the high audio of compact horn in thin material space the demand that is provided with, and set the heat dissipation problem that compact horn produces at solution, provide a kind of compact horn to set the radiator structure that improves of thin material space.

Compact horn of the present utility model is set the radiator structure that improves of thin material space; mainly be at mobile computer (NOTEBOOK); PDA(Personal Digital Assistant); the rear end metal pedestal of setting compact horn in the thin material space of LCD thin type electronics and IT products such as (LCD) is provided with a heat radiation guide plate; the metal pedestal that is provided with being heated with thermal energy conduction in the heat radiation guide plate on; to strengthen compact horn heat dissipation region area; avoid high temperature hot gas too to concentrate on and set the compact horn zone; and then directly strengthen the compact horn radiating efficiency; reduce the heating temp of the inner voice coil loudspeaker voice coil of compact horn and avoid being subjected to temperatures involved to burn; promote the stability of its output power simultaneously; and the shell that makes the thin type electronics and IT products is also unlikely has high temperature hot gas too to concentrate on to set the compact horn zone, reaches to have thin type electronics and IT products shell and avoid the safeguard measure that burnt by temperatures involved.

Below the specific embodiment that just adopted according to the utility model above-mentioned purpose, be described in detail in conjunction with the accompanying drawings.

Embodiment

See also embodiment shown in Figure 4; the utility model compact horn set thin material space improve radiator structure mainly lie in adopt on the rear end metal pedestal 11 of setting compact horn 1 be provided with one the heat radiation guide plate 2; this heat radiation guide plate 2 can be heat sink materials such as aluminium plate or copper coin material; and heat radiation guide plate 2 sticks glue 3 with can being coated with between metal pedestal 11 is docked; it is not unsettled to make metal pedestal 11 directly or indirectly attach heat radiation guide plate 2; the metal pedestal 11 that is provided with being heated with thermal energy conduction in the heat radiation guide plate 2 on; strengthened compact horn 1 heat dissipation region area; avoid high temperature hot gas too to concentrate on and set compact horn 1 zone; so directly strengthen compact horn 1 radiating efficiency; can reduce the heating temp of compact horn 1 inner voice coil loudspeaker voice coil; can avoid voice coil loudspeaker voice coil to be subjected to temperatures involved and burn; to prolong its serviceable life; and the stability that can promote its output power; the shell 4 of thin type electronics and IT products also strengthens because of compact horn 1 heat dissipation region simultaneously; make high temperature hot gas unlikely have too to concentrate on set compact horn 1 zone, avoid the safeguard measure that burnt by temperatures involved to reach shell 4 with thin type electronics and IT products.

Like this, the utility model just is that the compact horn of 2W is set not add radiator structure in the thin material space and add heat radiation guide plate 2 and done the temperature detection comparison with the output power, when compact horn continues 10 minutes input 2.83V voltage, impedance is that 4 Ω do output and detect the temperature that it sets on every side to be produced, therefore learn to the compact horn that adds radiator structure around it is set up to 86.1 ℃, and add heat radiation guide plate 2 compact horn its set around up to 59.7 ℃, find out that clearly setting the compact horn environment temperature has reduced by 26.4 ℃, allow high temperature hot gas unlikely have too to concentrate on set the compact horn zone, and then can avoid thin type electronics and IT products shell to be subjected to temperatures involved and to cause the situation of burning to take place, the compact horn bulk temperature also declines to a great extent simultaneously, formed the safeguard procedures that prevent that voice coil loudspeaker voice coil is caused by temperatures involved to burn, allow the high power output of compact horn can be more stable.

In sum, compact horn that the utility model provides is set the radiator structure that improves of thin material space, really can reach expection and improve the heat radiation purpose of setting compact horn, and it adopts the mode of directly strengthening radiating efficiency with the heat radiation guide plate on the metal pedestal of the rear end of compact horn, not only implement simple, it is low that cost is set, and this kind structure can bring very big improvement to set the radiating efficiency of compact horn.
