Abstract
The utility model relates to a sound box casing made from composite damping material, wherein the walls of the box are made from composite material. The walls of the box are prepared from the composite material with at least two structures. The outmost layer of the composite material is a rigid material layer, the inner layer of the composite material at least comprises a damping material layer, and the rigid material of the outer layer of the composite material is plastic cement, metal or wood, wherein the metal is aluminium alloy, zinc alloy, cast iron, steel or the like, and the damping material of the inner layer of the composite material is silica gel or rubber. The beneficial effects of the sound box casing made from composite damping material are that the composite material is adopted to make the casing, so that when the sound inside the sound box transmits to the walls of the casing, the sound is firstly absorbed by the damping material of the inner layer of the composite material and then contacts the rigid material of the outer layer of the composite material, thereby blocking the route of transmission of acoustic energy toward the casing and greatly attenuating or even eliminating sound coloration of the casing.
Description
[technical field]
The utility model relates to a kind of audio amplifier equipment, particularly a kind of sound box that adopts composite material to make the composite damping material of tank wall.
[background technology]
The tank wall of the sound box periphery of existing acoustic product resonance phenomena should not occur, thereby influences tonequality.This requires the material of casing should have suitable rigidity and internal damping attenuation characteristic.Low resonance demand high-power, the long stroke loud speaker that the wood chip density board casing of the certain damping of high gauge strips can satisfy, thus can avoid sound to dye and distortion phenomenon; And existing sound box part plastic cement, metal, the homogenous materials such as wooden of adopting are processed more; And, caused the easy resonance of sound box, so the sound box of processing by homogenous material because the wall ratio of the sound box that portability causes that people pursue now is thinner; When sound passes to the tank wall of audio amplifier; Cause the resonance of sound box easily, cause the sound of sound to dye and distortion, thereby make the variation of tonequality.
[summary of the invention]
The purpose of the utility model is to overcome deficiency of the prior art, and a kind of sound box that adopts the composite damping material that composite material makes is provided.
The utility model is to realize like this; Its tank wall is made by rigid material, and its improvements are, described tank wall adopts at least the composite material of double-layer structure to process; The outermost layer of described composite material is the rigid material layer, and internal layer comprises a damping material layer at least;
Preferably, the outermost rigid material layer of described composite material adopts plastic cement, metal or wooden;
Preferably, described metal is aluminium alloy, kirsite, cast iron, steel etc.;
Preferably, the damping material of described composite inner adopts silica gel or rubber;
Preferably, described composite material is that double-layer structure is formed, and skin is the rigid material layer, and internal layer is the damping material layer;
Preferably, described composite material is that three-decker is formed, and outermost layer is the rigid material layer, and the intermediate layer is the damping material layer, and bottom is the rigid material layer.
With old compared with techniques, the beneficial effect of the utility model:
The first is owing to adopted composite material to make casing; So when the sound in the audio amplifier passes to tank wall; The absorption of the damping material layer of process composite inner earlier; Touch the outer field rigid material of composite material again, so just blocked the route of transmission of acoustic energy, can lower even eliminate the sound coloration of casing significantly to casing.
It two is that the outermost rigid material of composite material adopts plastic material, metal material or wooden materials, and the extruding that can guarantee audio amplifier strenuous exercise is fallen to hit and is not damaged.
It three is also to be fixed with one deck rigid material in composite inner, and the tank wall intensity that it increases casing makes that tank wall is unlikely to be produced disagreeable casing sound coloration by the high sound pressure excitation.
[description of drawings]
Fig. 1 is the structure cutaway view of the sound box of the utility model composite damping material.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
As shown in Figure 1; The tank wall of the sound box of the composite damping material of the utility model adopts at least the composite material of double-layer structure to process, and the skin of described composite material is a rigid material layer 1, and internal layer comprises a damping material layer 2 at least; When sound arrives the tank wall of audio amplifier; Because after the absorption of the damping material layer 2 of process internal layer, it is outer to have only very small percentage to arrive, because rigidity and damping that outer field rigid material layer is possessed; So that the vibration of whole box body is extremely low, can not cause the phenomenon of the distortion and the sound coloration of sound.
The outer field rigid material layer 1 of above-mentioned composite material can adopt plastic material, metal material or wooden materials, and wherein said metal material can adopt aluminium alloy, kirsite, cast iron, steel etc.
The damping material layer 2 of above-mentioned composite inner can adopt silica gel material or elastomeric material.
When said composite material was double-layer structure, skin was the rigid material layer, and internal layer is the damping material layer.
At described composite material is that three-decker is formed; Outermost layer is the rigid material layer, and the intermediate layer is the damping material layer, and bottom is the rigid material layer; Said bottom is in order to increase the tank wall intensity of casing, the unlikely casing sound of being disliked by high sound pressure excitation generation of tank wall to be dyed.
According to the announcement and the instruction of above-mentioned specification, those skilled in the art in the invention can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the present invention is not limited to also should fall in the protection range of claim of the present invention modifications more of the present invention and change.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the present invention is not constituted any restriction.
