The utility model discloses a kind of damping suspension hook for multimedia loudspeaker box, comprise connecting ring, hemisphere connects cover, connecting cylinder, head rod, second connecting rod, first spring and the second spring, described first spring housing is contained on described head rod, and the upper end of described first spring is fixedly connected with the spacing catch of described head rod upper end, the lower end of described first spring is fixedly connected with the described inwall covered that is connected by the first rubber blanket, described second spring housing is contained on described second connecting rod, and the upper end of described second spring is fixedly connected with the spacing catch of described second connecting rod upper end, the lower end of described second spring is fixedly connected with by the lower end of the second rubber blanket with described connecting cylinder.The utility model, by the cushioning effect of the first spring, the second spring, the first rubber blanket, the second rubber blanket and the 3rd rubber blanket, is avoided vibration passing that audio amplifier sounding produces to body of wall, has therefore been cut off the propagation of overhead speaker, improve soundproof effect.
Description
Technical field
The utility model relates to a kind of damping device, particularly relates to a kind of damping suspension hook for multimedia loudspeaker box.
Background technology
All need in numerous place to carry out sound insulation process to it, present most of sound insulation process is all add Sound-proof material, application sound-deadening paint etc., but when multimedia loudspeaker box is lifted on indoor, only rely on Sound-proof material or sound-deadening paint etc. the sound wave that audio amplifier sends can only be completely cut off, therefore audio amplifier can produce vibration when sounding, the vibration of audio amplifier can conduct in body of wall by attachment screw, because now overall soundproof effect is poor, present great majority are all add a rubber blanket on the cap nut of suspension rod when installing, but cannot pad between screw rod and audio amplifier, so it can only play a bit, final sound still can reach body of wall by suspension rod.
Utility model content
The purpose of this utility model is just to provide a kind of damping suspension hook for multimedia loudspeaker box to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of damping suspension hook for multimedia loudspeaker box, comprise connecting ring, hemisphere connects cover, connecting cylinder, head rod, second connecting rod, first spring and the second spring, the described circular section end connecting cover is fixedly connected with the interior edge of described connecting ring, described connecting ring is fixedly connected with body of wall by multiple screw, the two ends on the described top and described connecting cylinder that connect cover are provided with through hole, the two ends of described head rod and the upper end of described second connecting rod are provided with spacing catch, the upper end of described head rod connects the through hole on cover top through described and be attached thereto, the lower end of described head rod is passed the through hole of described connecting cylinder upper end and is attached thereto, the upper end of described second connecting rod is passed the through hole of described connecting cylinder lower end and is attached thereto, the lower end of described second connecting rod is the suspended end of described audio amplifier, described first spring housing is contained on described head rod, and the upper end of described first spring is fixedly connected with the spacing catch of described head rod upper end, the lower end of described first spring is fixedly connected with the described inwall covered that is connected by the first rubber blanket, described second spring housing is contained on described second connecting rod, and the upper end of described second spring is fixedly connected with the spacing catch of described second connecting rod upper end, the lower end of described second spring is fixedly connected with by the lower end of the second rubber blanket with described connecting cylinder.
Particularly, the 3rd rubber blanket is provided with between the spacing catch of described head rod lower end and the upper end of described connecting cylinder.
Audio amplifier sounding produces vibration, and vibrate when being passed to suspension hook from casing of loudspeaker box, the multiple damping devices on suspension hook can avoid vibration passing on body of wall.
The beneficial effects of the utility model are:
The utility model is used for the cushioning effect of damping suspension hook by the first spring, the second spring, the first rubber blanket, the second rubber blanket and the 3rd rubber blanket of multimedia loudspeaker box, avoid vibration passing that audio amplifier sounding produces to body of wall, therefore cut off the propagation of overhead speaker, improve soundproof effect.

Fig. 2 is the upward view of the damping suspension hook for multimedia loudspeaker box described in the utility model, eliminates partial devices in figure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model is used for the damping suspension hook of multimedia loudspeaker box, comprise connecting ring 3, hemisphere connects cover 2, connecting cylinder 8, head rod 6, second connecting rod 11, first spring 7 and the second spring 10, connect the circular section end of cover 2 to be fixedly connected with the interior edge of connecting ring 3, connecting ring 3 is fixedly connected with body of wall 1 by multiple screw 4, the connection top of cover 2 and the two ends of connecting cylinder 8 are provided with through hole, the two ends of head rod 6 and the upper end of the second connecting rod 11 are provided with spacing catch, the upper end of head rod 6 is passed the through hole on connection cover 2 top and is attached thereto, the lower end of head rod 6 is passed the through hole of connecting cylinder 8 upper end and is attached thereto, the upper end of the second connecting rod 11 is passed the through hole of connecting cylinder 8 lower end and is attached thereto, the lower end of the second connecting rod 11 is the suspended end of audio amplifier, first spring 7 is sleeved on head rod 6, and the upper end of the first spring 7 is fixedly connected with the spacing catch of head rod 6 upper end, the lower end of the first spring 7 is fixedly connected with the inwall being connected cover 2 by the first rubber blanket 5, second spring 10 is sleeved on second connecting rod, and the upper end of the second spring 10 is fixedly connected with the spacing catch of the second connecting rod 11 upper end, the lower end of the second spring 10 is fixedly connected with the lower end of connecting cylinder 8 by the second rubber blanket 12, the 3rd rubber blanket 9 is provided with between the spacing catch of head rod 6 lower end and the upper end of connecting cylinder 8.
The operation principle that the utility model is used for the damping suspension hook of multimedia loudspeaker box is as follows:
Audio amplifier is suspended from the lower end of the second connecting rod 11, when audio amplifier sounding, the shell of audio amplifier produces vibration, after vibration passing to the second connecting rod 11, connecting cylinder 8 is passed to along the second connecting rod 11, after the one-level damping of the second spring 10, second rubber blanket 12 and the 3rd rubber blanket 9, be passed to along head rod 6 again and connect cover 2, then through the secondary damping of the first spring 7 and the first rubber blanket 5, last again by trickle vibration passing to body of wall 1, because have passed through repeatedly damping, the vibration that body of wall 1 receives can have been ignored.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection range of the present utility model.
