Problems solved by technology

The relative distance between the existing microphone and the teacher is changing, and the relative position of the microphone is uncertain, which causes the volume heard by the students to change
When the distance between the microphone and the teacher is far away, the volume will be too low, and the students cannot hear the teaching content clearly. Many existing microphones cannot face the population in working condition, which affects the sound reception. Manually make the microphone face the population. Long periods of time can cause arm fatigue and are difficult to sustain, and these conditions can also lead to poor teaching quality
At present, many hosts fix the microphone bracket on the head so that the microphone is facing the mouth. This method can ensure the sound quality and volume, but few teachers currently use this method

Embodiment approach 1

[0019] A teaching volume adjustment tool uses a support 3 to connect a deformable snakeskin tube 2 with a certain rigidity to a necklace 8, and the other end of the snakeskin tube is connected to a microphone 1, and the microphone is supported near the speaker's mouth.

[0020] The snake skin tube can be fixed on the support.

Embodiment approach 2

[0022] A teaching volume adjustment tool uses a support 3 to connect a deformable snakeskin tube 2 with a certain rigidity to a necklace 8, and the other end of the snakeskin tube is connected to a microphone 1, and the microphone is supported near the speaker's mouth.

[0023] The snake tube is detachable from the holder. There is no anti-rotation mechanism between the end of the snake skin tube and the support.

Embodiment approach 3

[0025] A teaching volume adjustment tool uses a support 3 to connect a deformable snakeskin tube 2 with a certain rigidity to a necklace 8, and the other end of the snakeskin tube is connected to a microphone 1, and the microphone is supported near the speaker's mouth.

[0026] The snake tube is detachable from the holder. An anti-rotation mechanism is arranged between the end of the snake skin tube and the support.

[0027] When the part of the end 4 of the snakeskin tube that matches the hole of the support is a non-circular structure, two planes are processed, namely a large plane and a small plane. A wedge-shaped space is formed between them, and the ball 5, spring 6, and catch 7 of the anti-rotation mechanism are located in the wedge-shaped space, there are at least two wedge-shaped spaces, and there are at least two sets of anti-rotation mechanisms. The baffle 7 is fixed on the large plane of the end 4 of the snake skin tube, the spring 6 is fixed on the small plane of ...

Abstract

The invention relates to a microphone used for teaching or hosting, in particular to a teaching volume adjustment tool. The support of the present invention is respectively connected with the necklace and the snake skin tube, the other end of the snake skin tube is connected with the microphone, and the microphone is supported near the speaker's mouth. The snake skin tube is deformed under force, and the position of the microphone changes with the deformation of the snake skin tube. The snake skin tube does not deform when it is not stressed. The snake skin tube is fixed on the support, or inserted into the support; the support is fixed on the necklace, or has a detachable connection with the necklace. The end of the snakeskin tube has an anti-rotation mechanism composed of springs, spheres, and blocking pieces. The present invention fully exerts the effect of the necklace, makes the necklace dual-purpose, and reduces the cost of the present invention. The decorative function of the necklace itself makes the necklace The invention is more beautiful, and the invention is convenient to carry, avoids the unfavorable situation that the teacher's teaching volume is too high or too low, and effectively prevents sound fluctuations. The invention can also be used for actors, show hosts and the like.

Description

technical field [0001] The invention relates to a microphone used for teaching or hosting, in particular to a teaching volume adjustment tool. Background technique [0002] In modern multimedia classrooms, especially classrooms with hundreds of people, it is necessary to have sound reinforcement and audio equipment, but the existing equipment is mostly evolved from stage and conference equipment, without considering the actual situation of teachers teaching , the use effect is insufficient. The relative distance between the existing microphone and the teacher changes, and the relative position of the microphone is uncertain, which causes the volume heard by the students to change. When the distance between the microphone and the teacher is far away, the volume will be too low, and the students cannot hear the teaching content clearly. Many existing microphones cannot face the population when they are working, which affects the sound reception. Manually make the microphone f...
