DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] Please refer to Figure 1-5 A teaching amplification device for Internet teaching comprises a base 1, a telescopic rod 2 is fixedly installed on the upper surface of the base 1, a groove 3 is provided on the upper surface of the telescopic rod 2, a limiting groove 4 is provided on the inner wall of the groove 3, a movable column 5 is movably installed on the inner wall of the groove 3, a limiting plate 6 is provided on the outer surface of the movable column 5, an outer frame 7 is fixedly installed on the upper surface of the movable column 5, a fixed column 8 is fixedly installed on the right inner wall of the outer frame 7, a first rack wheel 9 is movably installed on the left end of the fixed column 8, a fixed plate 10 is fixedly installed on the outer surface of the first rack wheel 9, a loudspeaker 11 is fixedly installed on the front surface of the fixed plate 10, a pipe sleeve 12 is fixedly installed on the left inner wall of the outer frame 7, a pipe column 13 is movably installed on the inner wall of the pipe sleeve 12, a second rack wheel 14 is fixedly installed on the right end of the pipe column 13, and a spring 15 is fixedly installed on the left end of the pipe column 13.

[0022] Specifically: the height of the loudspeaker 11 is adjusted by the telescopic rod 2, and the loudspeaker 11 is limited when it is rotated by the setting of the limit plate 6 and the limit groove 4, so as to prevent it from rotating again, and the movable column 5 is prevented from falling off from the inside of the groove 3 by relying on the gravity of the outer frame 7 and the loudspeaker 11 itself, and the first rack wheel 9 and the second rack wheel 14 are designed to achieve micro-angle adjustment of the loudspeaker 11, which is convenient and quick.

[0023] In this embodiment: the left surface of the first rack wheel 9 is meshedly connected with the right surface of the second rack wheel 14, a through groove is provided on the upper surface of the outer frame 7, the inner wall of the through groove is movably connected with the left and right surfaces of the fixed plate 10, and the left end of the spring 15 is fixedly connected to the right inner wall of the outer frame 7.

[0024] Specifically: when the first gear bar stops, the second gear bar limits the first gear bar. When the first gear bar moves, the rack on the first gear bar will form a leftward extrusion force on the second rack wheel 14, thereby pushing the second rack wheel 14 to move to the left. At this time, due to the resilience of the spring 15, the second rack wheel 14 will be pushed to the right. When the rack on the second rack wheel 14 enters between the rack gaps on the first rack wheel 9, it is limited.

[0025] In this embodiment, the size of the limiting groove 4 matches the size of the limiting plate 6 .

[0026] Working principle: When the utility model is in use, first plug in the wire plug 18 to power the loudspeaker 11, and the teaching staff speaks through the microphone, so that the sound is amplified and output through the loudspeaker 11. When it is necessary to adjust its height, the telescopic rod 2 is started, driving the movable column 5 and the upper loudspeaker 11 to move upward. After adjusting to the required height, the telescopic rod 2 stops. When it is necessary to rotate the loudspeaker 11, take out the outer frame 7 upward until the outer frame 7 can be rotated. After rotating to the required angle, push the movable column 5 back in, and the limit plate 6 enters the inside of the limit groove 4, thereby completing the limit of the movable column 5. At the same time, the pressure of the outer frame 7 and the loudspeaker 11 itself presses the movable column 5 not to move upward. When it is necessary to make a slight upward and downward angle adjustment, the teaching staff manually rotates the fixing plate 10, and the fixing plate 1 0 rotates, driving the first gear bar to rotate. When the first gear bar rotates, the rack on the first gear bar squeezes the second gear bar, and the second gear bar moves to the left. The rack on the second gear bar leaves the rack of the first gear bar and loses the limit on the first gear bar, thereby rotating. When the second gear bar moves to the left, the spring 15 contracts. When the rack on the second gear bar re-enters the rack of the first gear bar, the spring 15 rebounds, pushing the first gear bar and the second gear bar to engage. When the rotation stops, the first gear bar and the second gear bar are in an engaged state. Compared with the related art, the teaching amplification equipment for Internet teaching provided by the utility model has the following beneficial effects: the design can realize the adjustment of the loudspeaker 11 at multiple angles and multiple heights, thereby adjusting the orientation of the sound waves, thereby enhancing its practicality.

[0027] Embodiment 2:

[0028] Please refer to Figure 1-5 A wire winding groove 16 is provided on the lower surface of the base 1, a wire winding post 17 is fixedly installed on the upper inner wall of the wire winding groove 16, an outer surface of the wire winding post 17 is connected to a wire plug 18, a plug frame 19 is fixedly installed on the inner wall of the wire winding groove 16, and a battery 20 is fixedly installed on the upper surface of the base 1.

[0029] Specifically: Since the length of the wire of the wire plug 18 is fixed, when the wire plug 18 is completely wound around the surface of the winding pole 17, the plug of the wire plug 18 can be directly placed into the plug frame 19, and the battery 20 can provide power to the loudspeaker 11 for a short time. When the wire plug 18 is inserted, the battery 20 will be charged.

[0030] In this embodiment: the battery 20 is electrically connected to the loudspeaker 11 , the wire plug 18 is electrically connected to the loudspeaker 11 , and the wire plug 18 is electrically connected to the battery 20 .

[0031] Working principle: When the loudspeaker 11 is not needed, unplug the wire plug 18 and wind the wire along the winding pole 17. Since the length of the wire is fixed, when the wire is wound, the position of the plug is just below the plug frame 19. At this time, put the plug into the plug frame 19 to complete the winding. When the wire plug 18 cannot be used in the environment, the battery 20 can provide power for the loudspeaker 11 so that it can continue to be used. Compared with the related art, the teaching amplification equipment for Internet teaching provided by the utility model has the following beneficial effects: the design can protect the wires by winding them up, avoiding the situation where the wires are exposed to the outside and damaged when the loudspeaker 11 is idle. At the same time, the design of the battery 20 can provide power for the loudspeaker 11 in some special cases, thereby improving its scope of application.

[0032] The loudspeaker 11 is of an existing structure, and the control circuit can be realized by simple programming by those skilled in the art, which is common knowledge in the art. It is only used without modification, so the control method and circuit connection are not described in detail.

[0033] The above-mentioned equipment is used in different ways for each device. It is selected and used according to actual conditions, and various parameters are referred to, in accordance with the functions of the equipment used and the effects achieved.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
