There are six springs 73 and they are arranged at equal intervals. The other end of the spring 73 is fixedly connected to the bottom of the inner wall of the movable groove 71.

[0024] As a technical optimization scheme of the utility model, by arranging the transverse positioning mechanism 7, before the user places the speaker body 1 on the top of the bottom plate 2, the positioning strip 72 is pressed downward and contracted into the interior of the movable groove 71. At the same time, the spring 73 will be compressed and generate elastic force. After the speaker body 1 is completely placed on the bottom plate 2, the positioning strip 72 can be reset by the elastic force of the spring 73, and the positioning strip 72, the L-shaped positioning member 6 and the positioning plate 4 are used to position the speaker body 1 left and right, further improving the positioning effect of the bottom of the speaker body 1.

[0025] Reference Figure 3 , limiting blocks 10 are fixedly connected to both sides of the positioning strip 72. Limiting grooves 11 are arranged on both sides of the inner wall of the movable groove 71. The surface of the limiting block 10 is slidably connected to the inner wall of the limiting groove 11.

[0026] As a technical optimization scheme of the utility model, by arranging the limiting blocks 10 and the limiting grooves 11, during the process of the positioning strip 72 sliding up and down inside the movable groove 71, the limiting blocks 10 will be driven to move along the inner wall of the limiting groove 11, so as to be able to limit the positioning strip 72 left and right, prevent the positioning strip 72 from shifting during use, and at the same time prevent the positioning strip 72 from detaching from the movable groove 71.

[0027] Reference Figure 2 , a force-applying block 12 is arranged on the top of the bolt 9, and the force-applying block 12 is welded to the bolt 9.

[0028] As a technical optimization solution of the present utility model, by providing a force - applying block 12, when the user needs to rotate the bolt 9 to position the positioning plate 4, the user can apply force and rotate by pinching the force - applying block 12, which gives the user a convenient force - applying point of application. Then, by welding the force - applying block 12 to the bolt 9, the fixing strength of the force - applying block 12 is improved.

[0032] As a technical optimization solution of the present utility model, by providing the anti - slip grooves 14, when the user needs to rotate the force - applying block 12, the user's hand can contact the force - applying block 12 through the anti - slip grooves 14, thereby greatly increasing the friction between the user's hand and the force - applying block 12 and preventing the situation of slipping due to too low friction.

[0033] Reference Figure 2 , the bottom of the bottom plate 2 is fixedly connected with a soft pad 15, and the top of the left side of the positioning strip 72 is inclined.

[0034] As a technical optimization solution of the present utility model, by providing the soft pad 15, during the process of the user installing the speaker body 1 above the bottom plate 2 and using it, the soft pad 15 can buffer the vibration generated when the speaker body 1 starts. Then, by using the fact that the top of the left side of the positioning strip 72 is inclined, it is convenient for the user to directly fit and move along the inclined surface of the positioning strip 72 when installing the speaker body 1 on the top of the bottom plate 2, thereby pushing the positioning strip 72 to contract into the inside of the movable groove 71.

[0035] Working principle and usage process of the present utility model: When the user places the speaker body 1 on the top of the bottom plate 2, the stress plate 5 on the speaker body 1 can be inserted into the inside of the L-shaped positioning member 6. Then, rotate the pressing disc 3 so that one side of the pressing disc 3 fits with the rear stress plate 5 to position the stress plate 5 front and back. Then, when the pressing disc 3 rotates, it will drive the positioning plate 4 to move above the rear stress plate 5.

Before the user places the speaker body 1 on the top of the bottom plate 2, press the positioning strip 72 downward to shrink it into the inside of the movable groove 71. At the same time, the spring 73 will be compressed and generate elastic force. After the speaker body 1 is completely placed on the bottom plate 2, the positioning strip 72 can be reset by the elastic force of the spring 73, and the positioning strip 72, the L-shaped positioning member 6 and the positioning plate 4 are used to position the speaker body 1 left and right, further improving the positioning effect at the bottom of the speaker body 1. During the process of the positioning strip 72 sliding up and down inside the movable groove 71, it will drive the limiting block 10 to move along the inner wall of the limiting groove 11, so as to be able to limit the positioning strip 72 left and right, prevent the positioning strip 72 from shifting during use, and at the same time prevent the positioning strip 72 from detaching from the movable groove 71, and has the ability of bottom positioning.

[0036] In summary: For the speaker with good bottom positioning effect, by setting the stress plate 5, inserting the stress plate 5 into the inside of the L-shaped positioning member 6, and rotating the pressing disc 3, the stress plate 5 is positioned up and down, so that the speaker body 1 can be positioned up, down, front and back, solving the problem that the speaker is only positioned from top to bottom, resulting in the lack of front-back and left-right positioning effects at the bottom of the speaker. At this time, during the use of the speaker, the speaker will gradually shift left, right, front and back under the influence of vibration. In the case of a large offset distance, the speaker will fall down.
