[0002] Voice broadcasting equipment is a device used to convert sound information into electrical signals and play them through a broadcasting system. These devices are widely used in various fields, such as schools, hospitals, shopping malls, exhibition halls, etc., for delivering information, making announcements or playing background music, etc.

[0003] The existing patent CN220668935U voice broadcasting equipment has added the functionality of automatic and manual height adjustment, which enables the voice broadcasting equipment to be quickly telescopically adjusted, preventing the situation where the voice broadcasting equipment cannot be telescopically adjusted. Through the setting of the automatic lifting mechanism, the support plate can be automatically lifted and stored, improving the comfort of the user;

[0004] In the above-mentioned comparative documents, although the function of adjusting the height is added, the adjustment distance of the voice broadcasting device is limited due to the structural design of the height adjustment component. Therefore, when in use, the broadcasting range of the voice broadcasting device cannot be effectively increased by raising the height. Therefore, the utility model proposes a telescopic adjustable voice broadcasting device. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a telescopic and adjustable voice broadcasting device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a telescopic adjustable voice broadcasting device, comprising a broadcasting device body, the broadcasting device body comprising a support assembly, a control base, a connecting pipe and a sound amplification assembly, and an auxiliary support assembly is arranged on the connecting pipe;

[0008] The loudspeaker assembly comprises a mounting frame, which is inserted into the top of the connecting pipe. The top of the mounting frame is rotatably connected to a rotating seat, and the loudspeaker is rotatably connected to the rotating seat.

[0009] As a preferred embodiment, a second drive motor is embedded in the mounting frame, an output end of the second drive motor is connected to the rotating seat, a first drive motor is arranged on one side of the rotating seat, and an output end of the first drive motor is connected to the loudspeaker.

[0010] The beneficial effect of adopting the above further scheme is: the second drive motor provides power for the rotation of the rotating seat, and the broadcast range of the loudspeaker is changed by rotating the rotating seat. The loudspeaker is further driven to rotate by the first drive motor, so that the broadcast angle of the loudspeaker when in use is changed.

[0011] As a preferred embodiment, a first connecting sleeve is provided on the top of the connecting base, the inner wall diameter of the first connecting sleeve is adapted to the bottom diameter of the connecting pipe, a thread groove is provided at the bottom of the connecting pipe, and a first fixing sleeve is threadedly connected to the thread groove.

[0012] The beneficial effect of adopting the above further scheme is: the bottom of the connecting tube is clamped and connected by the first connecting sleeve, and the first connecting sleeve is further limited by rotating the first fixed sleeve to the top of the first connecting sleeve to prevent the first connecting sleeve from expanding outward during use, causing the connecting base to separate from the connecting tube.

[0013] As a preferred embodiment, a second connecting sleeve is provided on the top of the connecting pipe, the inner wall diameter of the second connecting sleeve is matched with the bottom diameter of the mounting frame, and a second fixing sleeve is threadedly connected to the mounting frame.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] 1. In the utility model, since the support assembly is a detachable structure, the number of connecting pipes can be increased as needed during use, thereby changing the overall height of the support assembly. First, the connecting pipes are assembled end to end as needed, and then the connecting base and the mounting frame are installed at both ends of the connecting pipe and limited by the first fixed sleeve and the second fixed sleeve to prevent the support assembly from being separated during use. The advantage of this structure is that the whole can be split into multiple sections during transportation for easy transportation.

[0023] 2. In the utility model, since the overall length of the support assembly is adjustable, when the support assembly is too long, an auxiliary support assembly is required to assist in supporting it, thereby increasing stability during use. The support assembly is assisted in supporting by the auxiliary support assembly, by clamping two arc-shaped clamping plates on the outside of one of the connecting tubes and fixing the two arc-shaped clamping plates with bolts. Under the design of the telescopic structure of the telescopic rod, the installation point of the mounting seat can be parallel to the installation point of the connecting base, thereby improving the stability of the device during use.

During use, the number of connecting pipes 4 can be increased as needed, thereby changing the overall height of the support assembly 2. First, the connecting pipes 4 are assembled end to end as required, and then the connecting base 31 and the mounting bracket 51 are installed at both ends of the connecting pipe 4 and limited by the first fixed sleeve 41 and the second fixed sleeve 52 to prevent the support assembly 2 from separating during use, thereby solving the technical problem of height adjustment of the support assembly 2.

[0040] Further, such as Figure 4 - Figure 5 As shown: a second drive motor 56 is embedded in the mounting frame 51, and the output end of the second drive motor 56 is connected to the rotating seat 53. A first drive motor 55 is arranged on one side of the rotating seat 53, and the output end of the first drive motor 55 is connected to the loudspeaker 54.
