fig. 2 is the internal structure schematic diagram of the vibration damping box of the sound box for reducing vibration transmission of the present invention.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, a speaker for reducing vibration transmission includes a main body 10, and a vibration damping box 20 is fixedly disposed below the main body 10.

Referring to fig. 2, the damping box 20 includes a box body 21, a damping plate 22 and a foot pad 23, the damping plate 22 is horizontally disposed in the box body 21, the damping plate 22 divides the interior of the damping box 20 into two independent cavities, and the cross section of the damping plate 22 is in a wave-shaped structure. By providing the damper box 20 below the cabinet main body 10, the transmission of the vibration generated in the cabinet main body 10 downward is reduced by the damper box 20.

The damping box 20 is internally provided with the damping plate 22, and the cross section of the damping plate 22 is a wavy knot, so that when music of the sound box main body 10 is transmitted to the damping box 20 through vibration, the vibration of sound is reflected and buffered by the damping plate 22, so that the vibration energy of the sound is consumed, the damping box 20 is internally partitioned by the damping plate 22 to form a cavity, the sound is enabled to have repeated oscillation effect in the cavity, and the transmission of the sound vibration is reduced.

The lateral surface of the inner wall of the box body 21 is provided with a bulge 24, the bulge 24 is arranged on the surface of the inner wall of the vibration damping box 20, and the foot pad 23 is arranged below the vibration damping box 20.

And be equipped with arch 24 on the inner wall of damping case 20, utilize arch 24 can further cushion the consumption to the sound vibration after damping plate 22 reflects to the produced vibration energy of audio amplifier main part 10 has been weakened, and the surface causes great influence to article on desktop and the desktop, and the noise when having avoided other article vibrations appears, improves people's effect of listening to, and the people of being convenient for use.

In the above-mentioned scheme, the quantity of callus on the sole 23 is five, and callus on the sole 23 corresponds four corners and the central point that damping case 20 put respectively and sets up. By supporting the four corners and the center of the vibration damping box 20, the main body 10 can be more stable when placed, and the situation of inclination can be avoided.

And the foot pad 23 includes a washer 231 and a spring 232, the spring 232 is disposed between the damping case 20 and the washer 231, and the washer 231 is located below the spring 232. Can cushion the consumption to the vibration that transmits to callus on the sole 23 through spring 232, when vibration transmits to spring 232 from damping case 20 below, through the elasticity of spring 232 self, make damping case 20 drive audio amplifier main part 10 and vibrate from top to bottom to reduce the influence of audio amplifier main part 10 to the desktop.

The outside of the vibration damping box 20 is provided with a sponge sleeve (not shown), the sponge sleeve wraps the surface of the vibration damping box 20, the sponge sleeve can be used for reducing noise of the vibration damping box 20, sound can be absorbed through the sponge sleeve, production of noise is reduced, and people can be more concentrated on the sound emitted by the sound box main body 10.

The number of the damping plates 22 is at least one, the damping plates 22 are arranged at intervals, and the damping plates 22 divide the interior of the damping box 20 into a plurality of cavities. The reflection and consumption of the sound vibration in the damping box 20 can be improved by increasing the number of the damping plates 22, thereby reducing the transmitted energy of the sound and improving the damping effect.
