Abstract
The utility model relates to a sound box provided with a damping sound suction structure. The outer part of a wall plate of a box body is provided with a speaker. The upper part of at least one wall plate outside a panel of the box body provided with the speaker is provided with a damping structure plate layer which is densely provided with small holes in a scattering mode along a plane surface. The small hole is filled with soft, elastic and acoustics damping material.
Description
The utility model relates to the audio amplifier in the seehears.
For audio amplifier in the raising seehears is particularly realized the high request that high-fidelity class audio amplifier truly reduces to music to the playback reproducibility of music, existing many deep researchs on the structural design of audio amplifier, and adopted many measures.As, swinging to hole site, size and quantitative improvement, to selecting for use of quality, density and the material of tank material etc.But in to the music playback process, eliminate aspect the noise that is produced because of self frequency vibration of tank material at present, very desirable solution is not arranged always as yet.
The purpose of this utility model is to provide a kind of at the problems referred to above to help to eliminate because of the caused noise of tank material self frequency vibration, improves music and broadcasts the audio amplifier of quality.
The alleged audio amplifier that is provided with the damping sound-absorbing structure of the utility model, be provided with loud speaker equally at the wallboards of box body place, at least one wallboard outside the cabinet panel at loud speaker place is provided with the formula that is dispersed in along the plane foraminate damping structure flaggy that gathers, be filled with the flexible acoustic damping material of gentle matter commonly used in its aperture, as artificial or natural high-molecular organic material, glass fiber material etc.
Aperture in the structure on the said damping structure flaggy can be through-hole form, also can be that opening inwardly makes interior to blind hole that the cabinet exterior face is kept perfectly; Both can take said aperture directly is opened in form on the wallboards of box body, and also can adopt said damping structure flaggy with holes is closely being covered in the version at wallboards of box body medial surface place.
Result of the test shows, sound box wallboard place such as the utility model are above-mentioned be provided with the damping sound-absorbing structure after, in the playback process because of vibration takes place and when producing corresponding natural noise when wallboards of box body material self frequency, this vibration can be set at acoustic damping material in the damping sound-absorbing flaggy at wallboard place effectively and absorb and be converted into heat energy, thereby eliminated the corresponding noise that it produced, the pure and penetrating sense of sound tonequality when having improved music playback greatly more satisfactoryly.Simultaneously, result of the test also shows, is opened in said aperture in the above-mentioned damping sound-absorbing flaggy with holes of the utility model, actually at aspects such as aperture, pitch-rows there is no special requirement.Particularly when adopting the form of directly perforate on wallboards of box body, can make wallboards of box body keep having under the prerequisite with enough structural strengths in structure between its hole, the quantity that said this aperture is offered is some more better than less effect.In addition, according to the difference of the selected material of wallboards of box body,, can make effect reach desirable more by suitably being adjusted at the acoustic damping material of filling in said this aperture.
Be understood that thus said structure principle of the present utility model obviously all is same being suitable for for the audio amplifier of various different types of structure and/or shape.
Below foregoing of the present utility model is described further with example shown in the drawings.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.
Fig. 1 is the structure chart of the utility model audio amplifier.
Fig. 2 is the structure chart that can adopt another kind of damping structure flaggy in the utility model audio amplifier.
As shown in Figure 1, this example is provided with the audio amplifier side of the being shape of damping sound-absorbing structure, front panel 1 place at casing is useful on the reserved location 5 that loud speaker is set, the wallboard 2 at least one other place in casing except that this panel 1 is as one in top board, backboard and the sidewall paneling etc. or while several damping structure flaggies 3 that are provided with the aperture 4 of evenly arranging in the plane.The material difference used according to wallboards of box body can be filled the also gentle matter elasticity acoustic damping material of the suitable material of cementation in this aperture 4.This damping structure flaggy 3 shown in the figure is for directly offering the version of through hole type aperture on roof box.In addition, said this damping structure flaggy 3 also can be for being provided with the interior version to blind hole type aperture that opening is inside and the wallboards of box body outer surface is kept perfectly on wallboards of box body.
Except that the said structure form, also can adopt as shown in Figure 2, the said damping structure flaggy 3 that is provided with through hole 4 and fills out intrinsic acoustic damping material is closely being covered in the version at wallboards of box body 2 medial surface places.
