Abstract
The utility model discloses an automatic heat radiation sound box, including a housing with an inner cavity, and at least one loudspeaker assembly mounted in the inner cavity of the housing, and the housing is also provided with a reversed phase hole matched with the external circumference of the magnetic pole of the loudspeaker assembly. The sound box is capable of radiating automatically during an operating period to prevent the temperature inside the box from increasing, so as to bear a great power and provide a good acoustic quality; simultaneously, the structure of the sound box is simple, and the sound box is easy to prepare.
Description
Technical field
The utility model relates to a kind of household electrical appliance, is specifically related to a kind of automatic heat radiation audio amplifier.
Technical background
Audio amplifier is a kind of chest that is used to place loud speaker, and it becomes sound transmission with audio signal.
The conventional small audio amplifier is that loud speaker sealing is installed in its inner chamber, and loud speaker works long hours in the process, and the heat that sends can't in time leave, and causes that temperature raises gradually in the casing, influences the tonequality of audio amplifier.
To sum up, develop a kind of audio amplifier, become the focus of paying close attention in the industry with excellent heat dispersion performance.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of automatic heat radiation audio amplifier, and it possesses good thermal diffusivity, and simple in structure.
For achieving the above object, the utility model adopts following technical scheme:
A kind of automatic heat radiation audio amplifier comprises the housing with an inner chamber, and is installed at least one loudspeaker assembly in the described housing inner chamber, and described housing is provided with the paraphase hole with described loudspeaker assembly magnetic pole outer peripheral edges size coupling.
Described housing comprises fore shell, and with the bonnet of fore shell snapping.
Described paraphase hole position is the round tube hole that is positioned on the described bonnet.
On the described bonnet inwall, be positioned at described round tube hole periphery and be provided with thermal wall.
The automatic heat radiation audio amplifier that the utility model is set forth, its beneficial effect is:
In the audio amplifier course of work, can automatic heat radiation, avoid the temperature of box house to raise, thereby can admit high-powerly, guaranteed tonequality simultaneously; Simultaneously, it is simple in structure, is convenient to manufacture.
Description of drawings
Fig. 1 is the structural representation of a kind of automatic heat radiation audio amplifier of the present utility model;
Fig. 2 is the scheme of installation of automatic heat radiation audio amplifier shown in Figure 1;
Fig. 3 is the structural representation of another kind of automatic heat radiation audio amplifier of the present utility model.
Embodiment
Below, in conjunction with the accompanying drawings and embodiment automatic heat radiation audio amplifier of the present utility model is described further so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, 2, automatic heat radiation audio amplifier of the present utility model comprises, fore shell 1, bonnet 3, fore shell 1 is fastened and connected with bonnet 3, forms an inner chamber between the two at it, one loudspeaker assembly 2 is installed in this inner chamber, near bonnets 3, and be matched with the position of U magnet 21 at the U magnet 21 of the rearward end of loudspeaker assembly 2, be provided with through hole 31 at bonnet 3, the outer peripheral edges of the shape of through hole 31 and U magnet 21 are all circle, and its size is slightly larger than U magnet 21 and gets cross section; When above-mentioned audio amplifier was installed, U magnet 21 was inserted in the through hole 31, thus, formed the paraphase hole of an annular at bonnet 3 places, and air feed stream flows out from this paraphase hole or flows into, and forms circulation of air flow, and radiating treatment is done in the whole side of the U magnet 21 of heating.Simultaneously, the inventor is also at the periphery of above-mentioned through hole 31, and the inwall that is positioned at bonnet 3 is provided with a thermal wall 32 along U magnet 21 length directions, and thermal wall 32 forms a gas channel with U magnet 21, so that the inflow of air-flow or outflow.
As shown in Figure 3, thermal wall 32` can also inwardly be postponed to the surface of loudspeaker assembly 2, so, and in the heat radiation process, the heat effective isolation that thermal wall 32` can distribute U magnet 21 sides is distributed in the external environment from through hole 31 in the outside of audio amplifier inner chamber.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to technical scheme described above and design.
