Abstract
The utility model relates to a damping sound box which includes a sound box body and a pedestal. The lower part of each side of the sound box body leans against the inner wall of the pedestal, but has no interacting force with the inner wall of the pedestal. The inside of the pedestal is filled with a damping material. One ends of four springs are fixed on the pedestal, and the other ends are fixed on the bottom of the sound box body. The damping material is the polystyrene spherical particle, and the diameter is from 4 to 10 millimeters. The fixing positions of the springs are symmetric about the center of the pedestal. The polystyrene has the excellent damping effect, and at the same time, the springs can play the excellent damping function, so the damping effect is realized, and the tone quality of the sound box is improved.
Description
Technical field
The utility model relates to a kind of audio amplifier, and in particular, it relates to a kind of vibrations that reduce, and improves the audio amplifier of tonequality.
Background technology
The small vibrations of making a point all can have influence on the tonequality of audio amplifier for audio amplifier, so it is very important to reduce the vibrations of audio amplifier.
At present, the sound-box device on the market all exists the problem of cushioning ability deficiency, so the strong sound-box device of the cushioning ability of development of new is particularly urgent.
Summary of the invention
The problem that the utility model solves is: provide a kind of stereo set can reduce to greatest extent vibrations, thereby improve the tonequality of audio amplifier.
Damping audio amplifier of the present utility model, comprise audio amplifier main body and base, base inner wall is being pasted in each bottom, side of described audio amplifier main body, but do not have interaction force with base inner wall, fill vibration-absorptive material in the described base, and have four spring one ends to be fixed on the base, the other end is fixed on the sound equipment bottom part body, described vibration-absorptive material is the polystyrene spherical particle, and diameter is between the 4-10 millimeter, and the fixed position of described spring is about the base Central Symmetry.
The beneficial effects of the utility model are:
(1) simple in structure;
(2) cheap;
(3) damping effect is obvious.
Description of drawings
Fig. 1 is stereogram of the present utility model;
Fig. 2 is structural representation of the present utility model.
Among the figure: audio amplifier main body 1 spring 21 bases 22 vibration-absorptive materials 23
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, damping audio amplifier of the present utility model comprises audio amplifier main body 1 and base 22, base 22 inwalls are being pasted in audio amplifier main body 1 each bottom, side, but there is not interaction force with base 22 inwalls, base 22 interior filling vibration-absorptive materials 23, and have four spring 21 1 ends to be fixed on the base 22, the other end is fixed on sound equipment main body 1 bottom, vibration-absorptive material 23 is the polystyrene spherical particle, and diameter is between the 4-10 millimeter, and the fixed position of spring 21 is about base 22 Central Symmetries.Polystyrene has good shock-absorbing effect, and spring also can play good cushioning effect simultaneously, thereby reaches damping, improves the purpose of audio amplifier tonequality.
