The suspension 411 is provided perpendicularly to the longitudinal direction of the main body, and extends across the main body 310 to be connected to the sound box 300. Wherein the suspension 411 comprises a recess 4111 and a screw 4112.

The recess 4111 is an opening provided in the hanging portion 411, and the opening is opposite to the hollow pillar 311. The concave notch 4111 may have a U shape or an Ω shape. The opening size is slightly smaller than the diameter of the buffer.

Fig. 2 schematically illustrates another loudspeaker enclosure vibration damper 100', where the vibration damper 400' includes a hanger 410', where the hanger 410' includes a suspension 411 'and a support 412, and the support 412 may be the same as the support shown in fig. 1A, for example, and the suspension 411' includes two concave notches 4111 and two screws 4112. The suspension 411' of the present embodiment differs from the suspension 411 in fig. 1A only in the number of recessed notches 4111 and screws 4112 provided.

In other alternative embodiments, more than two concave notches may be provided on the suspension portion according to the number of hollow columns.

In the embodiment of the present disclosure, the screw 4112 is disposed in the hollow column 311 and is used for limiting the buffer member 323 from separating from the hollow column 311, thereby realizing the limiting function on the buffer member 323.

The support portion 412 is connected to the keel 200, and in particular, the support portion 412 presses against the keel 200. Further, the bottom area of the support portion 412 is wider than the side edges of the keel 200, so that the support portion 412 is easily installed in alignment with the keel 200 and is not easily displaced.

Wherein, through the engagement of the concave notch 4111 with the hollow upright post 311 provided on the level difference platform, the lifting appliance 410 is provided on the level difference platform, and since the level difference platform is lower than the top surface of the main body, the length of the supporting portion of the lifting appliance 410 can be set shorter, and the gravity center of the lifting appliance is lower. Thereby enabling the spreader to be more firmly mounted on the keel.

The acoustic vibration damping device 100 of the ceiling further includes: a buffer 323, a first damper portion 11, and a second damper portion 12.

The cushioning material 323 may be a member having cushioning capability such as a rubber pad, and in this embodiment, the material may be rubber. The buffer member 323 is disposed around the outer side of the hollow pillar 311, and engages with the recess 4111.

The buffer 323 includes: an upper layer 3231, a lower layer 3232, and an engagement layer 3233 provided between the upper layer and the lower layer. The upper layer 3231 and the lower layer 3232 have the same diameter, and the engaging layer 3233 has a smaller diameter than the upper layer 3231 and the lower layer 3232, and has a shape of protruding upward and downward and recessed in the middle. After the concave notch 4111 is snapped into the engaging layer 3233, the diameter of the upper layer 3231 and the lower layer 3232 is larger than that of the engaging layer 3233, so as to limit the lifting tool 410 from moving up and down. In other alternative embodiments, the diameters of the upper and lower layers may be different, but the diameters of the upper and lower layers are greater than the diameter of the snap-in layers, thereby achieving the function of limiting movement of the spreader.

The first damper portion 11, the deformable material, for example, the material of the present embodiment may be a sponge. Is disposed at the junction of the support portion 412 and the keel 200. The embodiment is adhered to the bottom of the support.

The deformable material of the second shock absorbing portion 12, for example, the material of this embodiment may be a sponge. The second shock absorbing portion is provided on the inner circumference of the inner side of the panel 320, and the present embodiment makes a circle around the inner side of the panel, thereby preventing the problem of abnormal sound generated between the main body 310 and the panel 320 due to vibration.

At least two materials are used for the second damper portion 12, the first damper portion 11, and the cushioning material 323. That is, the second damper portion 12 is the same as the first damper portion 11 in terms of material, but the damper 323 is different in terms of material; or the second damper part 12 is the same as the damper 323, but the first damper part 11 is different in material; or the first shock absorbing portion 11 is the same as the material of the cushioning material 323, but the second shock absorbing portion 12 is different in material; or the second damper part 12 is different from the first damper part 11 and the cushioning material 323.

In the embodiment of the present utility model, the acoustic shock absorbing apparatus further includes a deformation member 13 for restricting the movement of the panel 320 with respect to the keel 200 in the mounted state of the panel 320 with respect to the keel 200.

As shown in fig. 3, when the panel 320 is mounted on the keel 200, the upper side of the deformation member 13 is engaged with the keel 200, and the lower side has a position where the deformation member 13 is bent and protruded, when the panel 320 is mounted on the keel 200, the deformation member 13 is separated from the keel 200 by an external force so that the first flange 321 is engaged between the keel 200 and the deformation member 13, and the deformation member 13 is clamped by a reaction force so as to limit the movement of the panel 320 relative to the keel 200, thereby realizing a limiting effect on the panel 320.

The above is a detailed description of the specific structure of the sound equipment.

The following describes in detail the method of attaching the sound equipment to the ceiling joist.

In order to prevent the panel 320 from being separated from the main body 310, the side surface of the main body 310 is provided with a bump 330, and an opening 3221 on the second flange 322 of the panel 320 is clamped on the bump 330, so that the panel 320 is connected with the main body 310 and can form a certain displacement with the main body. As shown in fig. 3, when the sound box 300 is installed, the first flange of the panel 320 is forcibly pushed between the keel 200 and the deformable member 13 by inserting the body 310 and the panel 320 between the keel 200. At this time, the deformation member 13 originally attached to the keel 200 is separated from the keel 200 by an external force, so that the first flange 321 is clamped between the keel 200 and the deformation member 13, and the deformation member 13 is clamped to the first flange 321 by a reaction force. In the process that the first flange 321 moves upwards, the opening 3221 on the second flange 322 is displaced, the edge of the opening 3221 is away from the bump 330, and when the panel 320 is installed, the edge of the opening 3221 is not contacted with the bump 330, that is, the vibration of the main body 310 is not transmitted to the panel through the bump 330.

Then, a hanger 410 is placed at one end of the main body 310, after the concave notch 4111 is aligned with the hollow upright post 311 where the buffer member has been installed, the hanger 410 is engaged with the buffer member 323 provided around the hollow upright post 311, and the supporting portion 412 is placed on the keels 200 at both sides while engaged, and after the screw 4112 is installed in the hollow upright post 311, one-side installation is completed. In the same manner, after another set of hangers is installed at the other end of the main body 310, the entire installation is completed.

In the above process, the connection between the lifting appliance 410 and the hollow upright post 311 enables the main body 310 of the sound box 300 to be suspended between the adjacent keels 200, and when the sound box 200 plays music, the vibration generated by the loudspeaker causes the vibration of the main body 310, and since the side surface of the main body 310 is not contacted with the keels 200, the vibration is not transmitted to the keels 200 through the side surface of the main body 310 due to the large area of the main body 310, and the noise generated by the vibration is greatly reduced.

Further, in order to reduce the transmission of noise generated by vibration, the buffer 323 is provided outside the hollow upright 311, so that the contact between the hanger 410 and the hollow upright 311 can be avoided. Furthermore, the first damping portion 11 is further disposed on the bottom surface of the supporting portion 412, so that not only can the lifting appliance be stably mounted on the keel, friction is increased, the lifting appliance is prevented from being separated from the keel due to the influence of vibration, but also noise can be further prevented from being transmitted.

In addition, since the main body 310 is suspended between the adjacent keels 200, even if the main body 310 is attached to the panel 320 after the panel 320 is mounted, the main body 310 does not apply force to press the second shock absorbing portion 12 provided inside the panel, that is, the main body 310 is in contact with the second shock absorbing portion 12 but does not excessively deform the second shock absorbing portion 12. This arrangement prevents vibration from being transmitted to the panel 320, and the seal between the main body 310 and the panel 320 prevents sound leakage and also extends the service life of the second damper portion 12.

In the present embodiment, the second damper portion 12, the first damper portion 11, and the cushioning material 323 are made of different materials. Since the vibration frequency of sound is related to the wave source, when a piece of music is played, vibrations of different frequencies are generated in the sound. For example, the first damper portion 11 and the second damper portion 12 in the present embodiment are sponge, and the buffer 323 is made of rubber, and has a damping effect on vibrations of different frequencies.

Furthermore, as shown in fig. 1A, in an embodiment, when the spreader is a relatively deformable plastic, two hollow upright posts, that is to say a total of 4, may be provided at each end of the body. Correspondingly, the concave notch on each lifting appliance is respectively provided with two concave notches. In this way, the connection between the lifting appliance and the main body can be further stabilized, so that the suspension of the main body is more stable.

The present embodiment has been described in detail with reference to the accompanying drawings. From the above description, the person skilled in the art should have a clear knowledge of the utility model.

It should be noted that, in the drawings or the text of the specification, implementations not shown or described are all forms known to those of ordinary skill in the art, and not described in detail. Furthermore, the above definitions of the elements are not limited to the specific structures, shapes or modes mentioned in the embodiments, and may be simply modified or replaced by those of ordinary skill in the art.

While the foregoing is directed to embodiments of the present utility model, other and further details of the utility model may be had by the present utility model, it should be understood that the foregoing description is merely illustrative of the utility model and that no changes, substitutions and alterations herein may be made without departing from the spirit and principles of the utility model.
