[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0028] Combine the following Figures 1 to 3 , describing an embodiment of the present invention.
[0029] According to an embodiment of the present invention, a classroom sound amplification device is provided, comprising: a radio mechanism 1 and a control mechanism 3 .
[0030] Specifically, the radio mechanism 1 is movably arranged in the classroom, and the radio mechanism 1 is connected to the speaker 2 in the classroom to transmit the received sound to the speaker 2 for playback. The control mechanism 3 is connected to the radio mechanism 1 to drive the radio mechanism 1 to move, and the control mechanism 3 is connected to the positioning unit signal carried by the teacher. The control mechanism 3 controls the movement of the radio mechanism 1 by receiving the signal of the positioning unit, so that the distance between the radio mechanism 1 and the teacher is the set distance.
[0031] In this embodiment, the teacher can carry the positioning unit before giving a lecture, so that during the lecture the positioning unit will continuously transmit signals to the control mechanism 3. When the teacher moves, the control mechanism 3 controls the radio mechanism 1 to move to ensure the reception effect of the radio mechanism 1. At the same time, the control mechanism 3 will control the distance between the radio mechanism 1 and the teacher so that the distance always remains at the set distance. The radio mechanism 1 is connected to the speaker 2 in the teacher's room. The radio mechanism 1 can receive the teacher's voice and convert it into a data signal to be transmitted to the speaker 2. The speaker 2 then plays the teacher's voice to achieve the effect of amplifying the sound.
[0032] It should be noted that, by setting up a radio mechanism 1 to collect the teacher's voice and then transmit it to the speaker 2 in the classroom for playback, the problem of poor sound amplification effect of the sound reinforcement equipment is effectively avoided. At the same time, the teacher carries a positioning unit, so that the control mechanism 3 receives the signal to control the radio mechanism 1 to move, so that no matter where the teacher is teaching, the radio mechanism 1 can receive the sound and ensure the sound amplification effect. Furthermore, the control mechanism 3 can also control the radio mechanism 1 to maintain a set distance from the teacher. The set distance can ensure the sound reception effect of the radio mechanism 1 and effectively avoid the defects of different or unclear volumes of the sound played in the speaker 2. The classroom sound reinforcement device of this embodiment can effectively improve the teaching effect and teaching efficiency.
[0033] In some embodiments, a speaker switching structure is provided on the moving path of the radio mechanism 1. When the radio mechanism 1 moves to a designated position, the radio mechanism 1 is connected to the speaker switching structure to switch the sound-emitting speaker 2 from the speaker 2 at the front side of the classroom to the speaker 2 at the back side of the classroom, or to switch the speaker 2 at the back side of the classroom to the speaker 2 at the front side of the classroom.
[0034] In this embodiment, when the radio mechanism 1 is in the initial position, the radio mechanism 1 is connected to the speaker 2 at the back of the classroom. At this time, the teacher is at the front of the classroom or on the podium. The radio mechanism 1 receives the teacher's voice and converts it into data information to transmit to the speaker 2 at the back of the classroom. The speaker 2 at the back of the classroom can play the teacher's voice, and the students at the back of the classroom can also clearly hear the teacher's voice. In the process of the teacher moving from the front of the classroom to the back of the classroom, the control mechanism 3 receives the information of the positioning unit to control the radio mechanism 1 to move. When the teacher moves to the back of the classroom, the radio mechanism 1 will also move to the back of the classroom with the teacher. During its movement, it will be connected to the speaker switching structure. The radio mechanism 1 will switch the connected speaker 2 from the speaker 2 at the back of the classroom to the speaker 2 at the front of the classroom. The students at the front of the classroom can also clearly hear the voice of the teacher at the back of the classroom. Similarly, when the teacher moves to the front of the classroom, the radio mechanism 1 will also move to the front of the classroom with the teacher. During its movement, it will be connected to the speaker switching structure. The radio mechanism 1 will switch the connected speaker 2 from the speaker 2 at the front of the classroom to the speaker 2 at the back of the classroom.
[0035] Preferably, the speaker switching structure is a touch structure, and the speaker 2 can be switched after the radio structure 1 touches the speaker switching structure. The speaker switching structure is connected to the front speaker 2 and the back speaker 2 of the classroom, and is used to control the sound of the speaker 2. In the initial state, the speaker switching structure controls the back speaker 2 to sound, and the front speaker 2 stops sounding, so the back speaker 2 can play the teacher's voice; when the teacher moves to the back of the classroom, the radio structure 1 touches the speaker switching structure during the movement, and the speaker switching structure controls the front speaker 2 to sound, and the back speaker 2 stops sounding, so the front speaker 2 can play the teacher's voice.
[0036] It should be noted that by setting up a speaker switching structure, the speakers 2 at the front and back of the classroom can be effectively switched. When the teacher is at the back of the classroom, the students at the front of the classroom can also clearly hear the teacher's voice. When the teacher is at the front of the classroom, the students at the back of the classroom can also clearly hear the teacher's voice, which effectively improves the teaching effect.

[0038] In this embodiment, the first switching structure 4 is connected to the speaker 2 at the back of the classroom to control the speaker 2 at the back of the classroom to sound or stop sounding, and the second switching structure 5 is connected to the speaker 2 at the front of the classroom to control the speaker 2 at the front of the classroom to sound or stop sounding. The first switching structure 4 and the second switching structure 5 are both arranged on the moving path of the radio mechanism 1. The dividing point between the first switching structure 4 and the second switching structure 5 is located in the middle of the classroom. The first switching structure 4 extends from the middle of the classroom to the front of the classroom, and the second switching structure 5 extends from the middle of the classroom to the back of the classroom. When the teacher is at the front of the classroom, the radio mechanism 1 is in continuous contact with the first switching structure 4 to ensure that the speaker 2 at the back of the classroom sounds; when the teacher moves from the front of the classroom to the back of the classroom, when the radio mechanism 1 moves to the middle of the classroom, the radio mechanism 1 switches from contacting with the first switching structure 4 to contacting with the second switching structure 5, the speaker 2 at the back of the classroom stops sounding, and the speaker 2 at the front of the classroom sounds.

The movement of the moving component drives the microphone 6 to move, and the microphone 6 receives sound and transmits data information to the speaker 2 for playback. The moving component continues to be connected to the first switching structure 4 or the second switching structure 5 during the movement.
[0042] In some embodiments, it further comprises: a guide rail 8. The guide rail 8 is arranged on the top of the classroom, and the moving component is movably arranged on the guide rail 8, and the path along which the moving component moves in the guide direction of the guide rail 8 constitutes the moving path.
