Description

Technical Field

[0001] This utility model relates to the field of public address technology, specifically to an audio device for public address systems. Background Technology

[0002] Audio equipment is mainly used for broadcasting and amplification, and is mostly used for public broadcasting. It can be used in schools or large shopping malls, and can also be used outdoors. When used outdoors, it is usually installed on a pole for easy broadcasting.

[0003] Existing audio equipment has certain drawbacks in use. Most public address audio equipment is fixed to a column using mounting rings. In practical applications, it is often necessary to broadcast to different directions using the audio equipment. Usually, staff members use a ladder to climb to a higher position, loosen and remove the fasteners on the mounting ring, rotate the mounting ring to adjust the position of the audio equipment, and then fix the mounting ring to the column. This adjustment method is cumbersome, and because the audio equipment is heavy, staff members need to support the equipment when disassembling or fixing the mounting ring, which poses a risk of falling and a safety hazard.

[0036] Example 3: As Figure 1-10 The device includes a mounting rod 1 and a speaker body 2. A mounting base 3 is fixedly mounted on the outer wall of the mounting rod 1. A mounting groove 301 is formed on the inner wall of the upper end of the mounting base 3. A mounting mechanism for mounting the speaker body 2 is provided on the outer wall of the mounting rod 1.

[0038] The above structures and principles are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0039] The working principle of this utility model is as follows: When installing the speaker body 2, the two connecting seats 61 on the rear side of the mounting plate 6 are slidably installed on the outer wall of the mounting rod 1, and the first insert rod 43 on the lower side is inserted into the slot 62 opened in the inner wall of the lower connecting seat 61. The speaker body 2 is slidably inserted into the inner wall of the limiting rod 63, and at the same time, the slide rod 21 is slidably installed into the inner wall of the slide groove 601. Then, the top plate 71 with the connecting plate 72 is slidably installed on the outer wall of the mounting rod 1, so that the second insert rod 74 on the lower side of the connecting plate 72 can be inserted into the slot 62 in the inner wall of the upper connecting seat 61. The position of the top plate 71 is adjusted by rotation so that the fixing bolt 73 can be inserted into the inner wall of the mounting hole 101. The fixing bolt is then rotated and installed. Simply tighten the nuts on the outer wall of the speaker body 73. When it is necessary to disassemble the speaker body 2, simply reverse the operation. When it is necessary to adjust the position of the speaker body 2, start the motor 5. The motor 5 drives the rotating shaft 51 to rotate, causing the first gear 52 on the outer wall of the rotating shaft 51 to rotate, thereby driving the second gear 53 to rotate, causing the gear ring 42 to rotate. At this time, the base plate 4 has a tendency to rotate. Through the limit between the first insert rod 43 and the connecting seat 61, the connecting seat 61 rotates with the rotation of the base plate 4. At the same time, when the connecting seat 61 rotates, it will drive the second insert rod 74 to rotate. At this time, the connecting plate 72 rotates at the lower end of the top plate 71, so that the speaker body 2 can rotate around the mounting rod 1.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
