Description

Technical Field

[0001] The utility model relates to the technical field of stage sound systems, in particular to a suspended anti-falling stage sound system. Background Art

[0002] Suspended stage sound is a type of stage sound. With the continuous development of modern society, professional sound equipment used for stage performances and outdoor open-air sound fields need to be suspended speakers. The speaker placement position cannot be too low. The sound waves of low-position speakers are easily absorbed by the audience's body, resulting in grazing sound absorption, especially causing great loss of mid- and high-frequency sounds, so suspended speakers should be used for installation.

[0003] The existing stage audio system has certain drawbacks during use. In order to facilitate the transmission of the sound to the people at low places, the audio system needs to be tilted toward the people at low places. Since the stage audio system lacks a limiting structure, the speakers in the audio system are prone to slip off the hanger when tilted.

[0004] For this reason, those skilled in the art have proposed a suspended anti-falling stage sound system to solve the problems raised in the above background. Utility Model Content

[0005] The utility model aims to provide a suspended anti-drop stage sound system to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A suspended anti-drop stage sound system, comprising a hanging plate and:

[0008] A height adjustment structure mounted on a lifting plate;

[0009] A deflection mechanism fixedly connected to the height adjustment structure;

[0010] An anti-slip sound installed on a deflection mechanism, the anti-slip sound includes a box connected to the deflection mechanism, the box is provided with a mounting opening, a motor frame is fixedly installed on a side of the box away from the mounting opening, a double-output shaft motor is fixedly installed on the motor frame, a lead screw is fixedly installed on the output end of the double-output shaft motor, the lead screw is threadedly connected to a linkage frame, a retaining frame slidably connected to the box is fixedly installed on the linkage frame, and a speaker is installed in the box.

[0011] As a further improvement scheme of the utility model: the height adjustment structure includes a sleeve body fixedly connected to the lifting plate, a spring is fixedly installed on one side of the sleeve body, the spring is fixedly connected to a plug-in bracket, a handle is fixedly installed on one end of the plug-in bracket, a hanger is slidably installed in the sleeve body, the hanger is fixedly connected to the deflection mechanism, and a plurality of groups of first positioning holes are provided on the hanger, one group of which is movably connected to the plug-in bracket.

[0012] As a further improvement scheme of the utility model: the deflection mechanism includes an articulated seat fixedly connected to the hanger, guide frames are hinged on both sides of the articulated seat, threaded parts are threaded on the guide frames, a handle hinged to the box body is slidably installed on the guide frame, multiple groups of second positioning holes are provided on the handle, the second positioning holes are movably connected to the threaded parts, and the articulated seat is articulated with an articulated frame fixedly installed on the box body.

[0013] As a further improvement of the utility model: a wire passage opening is provided on the box body.

[0014] As a further improvement of the utility model: a plurality of groups of weight-reducing holes are provided on the box body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The height adjustment structure adjusts the height of the deflection mechanism, and the deflection mechanism adjusts the angle of the box. When the speaker needs to be installed in the box, the deflection mechanism makes the box flat, and then under the drive of the double-output shaft motor, the screw rod rotates and drives the linkage frame to move, and the linkage frame drives the blocking frame to move, so that the blocking frames are separated from each other, thereby releasing the blocking of the installation opening by the blocking frame, and then the speaker is placed in the box. Under the drive of the double-output shaft motor, the double-output shaft motor drives the screw rod to reverse, so that the linkage frames are close to each other, and the linkage frame drives the blocking frames to be close to each other, so that the blocking frame blocks the installation opening of the box, thereby preventing the speaker from slipping out of the installation opening. When the box is used to hoist the speaker, the blocking frame is used to block the installation opening, thereby preventing the speaker from slipping out of the box when the box is tilted.

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] Example 1, see Figure 1 to Figure 3 As shown, a suspended anti-drop stage sound system includes a hanging plate 1 and further includes:

[0023] A height adjustment structure 2 mounted on the lifting plate 1;

[0024] A deflection mechanism 3 fixedly connected to the height adjustment structure 2;

[0025] An anti-slip sound 4 is installed on the deflection mechanism 3, and the anti-slip sound 4 includes a box 5 connected to the deflection mechanism 3, a mounting port 6 is provided on the box 5, a motor frame 7 is fixedly installed on the side of the box 5 away from the mounting port 6, a double-output shaft motor 8 is fixedly installed on the motor frame 7, a screw rod 9 is fixedly installed on the output end of the double-output shaft motor 8, a linkage frame 10 is threadedly connected to the screw rod 9, a retaining frame 11 slidably connected to the box 5 is fixedly installed on the linkage frame 10, and a sound box 12 is installed in the box 5.

[0026] The height adjustment structure 2 adjusts the height of the deflection mechanism 3, and the deflection mechanism 3 adjusts the angle of the box 5. When the speaker 12 needs to be installed in the box 5, the deflection mechanism 3 makes the box 5 flat, and then under the drive of the double-output shaft motor 8, the screw rod 9 rotates and drives the linkage frame 10 to move, and the linkage frame 10 drives the blocking frame 11 to move, so that the blocking frames 11 are separated from each other, thereby removing the blocking of the installation opening 6 by the blocking frame 11, and then the speaker 12 is placed in the box 5. Under the drive of the double-output shaft motor 8, the double-output shaft motor 8 drives the screw rod 9 to reverse, so that the linkage frames 10 are close to each other, and the linkage frame 10 drives the blocking frame 11 to be close to each other, so that the blocking frame 11 blocks the installation opening 6 of the box 5, thereby preventing the speaker 12 from slipping out of the installation opening 6. When the box 5 is used to hoist the speaker 12, the blocking frame 11 is used to block the installation opening 6, thereby preventing the speaker 12 from slipping out of the box 5 when the box 5 is tilted.

[0027] In one case of this embodiment, the height adjustment structure 2 includes a sleeve 13 fixedly connected to the hanging plate 1, a spring 14 is fixedly installed on one side of the sleeve 13, a plug-in bracket 15 is fixedly connected to the spring 14, a handle 16 is fixedly installed on one end of the plug-in bracket 15, a hanger 17 is slidably installed in the sleeve 13, the hanger 17 is fixedly connected to the deflection mechanism 3, and a plurality of groups of first positioning holes 18 are provided on the hanger 17, one group of the first positioning holes 18 is movably connected to the plug-in bracket 15. Pulling the handle 16 causes the handle 16 to drive the plug-in bracket 15, so that the plug-in bracket 15 is separated from the first positioning holes 18, thereby adjusting the position of the hanger 17, and then under the pulling of the spring 14, the plug-in bracket 15 is reset and reinserted into the first positioning holes 18.
