Description

Technical Field

[0001] The utility model relates to the technical field of multimedia, in particular to a universal assembled speaker for multimedia. Background Art

[0002] With the development of teaching, multimedia teaching equipment has gradually entered campuses, and multimedia equipment can be used to intuitively display teaching video images and audio to students. Ceiling speakers are gradually being used in multimedia venues because they can be installed in conjunction with the ceiling of multimedia venues and have good aesthetics.

[0003] However, the ceiling is generally parallel to the ground, so that the sound playback angle of the speakers installed in conjunction with the ceiling is usually only downward, resulting in the sound played by the speakers in multiple locations being unable to be well concentrated toward the crowd, affecting the listening quality of multimedia audio.

[0004] The existing speakers installed on the ceiling of multimedia teaching venues have the following disadvantages: the existing speakers used in multimedia cannot be well assembled with the ceiling and cannot adjust the sound propagation angle. To this end, we propose a universal assembled speaker for multimedia. Summary of the invention

[0005] The main purpose of the utility model is to provide a universal assembled speaker for multimedia, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A universal assembled audio system for multimedia, comprising a flange ring, a sleeve and an angle adjustment component, a speaker and a hemispherical dustproof mesh cover, wherein the sleeve is mounted on the top of the flange ring by bolts, the angle adjustment component cover is arranged on the top of the sleeve, and the speaker is located in the sleeve;

[0008] The angle adjustment component comprises a supporting plate, a ball seat, a sphere, a screw rod and a ball pressing sleeve.

[0009] Furthermore, the ball seat is fixedly connected to the center of the bottom of the support plate, half of the sphere is placed in the ball seat, the ball pressing sleeve is covered on the other half of the sphere, and the outer periphery of the ball pressing sleeve and the ball seat are riveted by bolts.

[0010] Furthermore, the screw is fixedly connected to the bottom of the sphere, a threaded hole corresponding to the screw is opened on the top of the speaker, and the speaker is threadedly fixed to the screw through the threaded hole.

[0011] Furthermore, the support plate is fixedly connected to the top of the sleeve.

[0012] Furthermore, the hemispherical dustproof mesh cover is fixedly connected to the bottom of the flange ring.

[0013] Compared with the prior art, the utility model has the following beneficial effects: through the assembly consisting of the flange ring, the sleeve, the angle adjustment component, the speaker and the hemispherical dustproof mesh cover, a set of audio structure with universally adjustable broadcasting angle is provided for multimedia teaching, and the audio of the present application can be embedded and installed in the indoor ceiling for use. The broadcasting angle of the speaker can be adjusted through the angle adjustment component, so that the direction of sound propagation is more in line with the spatial environment of multimedia teaching, which helps to better propagate the sound to the location of the audience, so that the audio of the present application can be installed on the ceiling and at the same time, the angle of sound propagation can be flexibly controlled, so that the audio has both aesthetics and practicality, and solves the problem that the audio used in the existing multimedia cannot be well assembled with the ceiling and cannot adjust the sound propagation angle.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a universal assembled audio system for multimedia includes a flange ring 1, a sleeve 2 and an angle adjustment component 3, and also includes a speaker 4 and a hemispherical dustproof mesh cover 5. The sleeve 2 is installed on the top of the flange ring 1 by bolts, the angle adjustment component 3 is covered on the top of the sleeve 2, and the speaker 4 is located in the sleeve 2; the angle adjustment component 3 includes a support plate 301, a ball seat 302, a sphere 303, a screw 304 and a ball pressing sleeve 305.

[0021] The ball seat 302 is fixedly connected to the center of the bottom of the support plate 301, half of the sphere 303 is placed in the ball seat 302, the ball pressing sleeve 305 covers the other half of the sphere 303, and the outer periphery of the ball pressing sleeve 305 and the ball seat 302 are riveted by bolts.

[0022] The screw rod 304 is fixedly connected to the bottom of the sphere 303 , and a threaded hole 6 corresponding to the screw rod 304 is opened on the top of the speaker 4 . The speaker 4 is threadedly fixed to the screw rod 304 through the threaded hole 6 .

[0023] The support plate 301 is fixedly connected to the top of the sleeve 2 .

[0024] The hemispherical dustproof mesh cover 5 is fixedly connected to the bottom of the flange ring 1 .

[0025] It should be noted that the utility model is a universal assembled audio system for multimedia. During operation, the audio assembly personnel open holes corresponding to the flange ring 1 on the ceiling of the multimedia teaching venue, then insert the sleeve 2 and the angle adjustment component 3 into the holes of the ceiling, bolt the flange ring 1 to the ceiling with bolts, and connect the wires of the speaker 4 to the multimedia equipment to complete the assembly of the audio system.
