[0023] By rotating the rotating block 3, the rotating block 3 drives the rotating shaft 23 to rotate, the rotating shaft 23 drives the bidirectional threaded rod 28 to rotate, the bidirectional threaded rod 28 drives the threaded block 29 to move, and the threaded block 29 drives the clamping plate 2 to move inward to clamp and fix the speaker 1, and by starting the motor 4, the motor 4 drives the connecting shaft 24 to rotate, the connecting shaft 24 drives the bevel gear 1 25 to rotate, the rotation of the bevel gear 1 25 drives the bevel gear 2 26 to rotate, the rotation of the bevel gear 2 26 drives the support shaft 27 to rotate, and the support shaft 27 drives the rotating table 11 to rotate, so that the facing direction of the speaker 1 can be changed, so that the sound can be transmitted at different angles in the horizontal direction.

[0024] Reference Figure 2 A gasket 12 is provided inside the speaker 1, a dust cap 13 is provided at the lower part of the gasket 12, a diaphragm 14 is provided at the lower part of the dust cap 13, a bracket 15 is provided at the lower part of the diaphragm 14, a terminal 16 is provided at the lower part of the bracket 15, a voice coil 17 is provided at the lower part of the terminal 16, a spring 18 is provided at the lower part of the voice coil 17, a secondary magnet 19 is provided at the lower part of the spring 18, a washer 20 is provided at the lower part of the secondary magnet 19, a magnet 21 is provided at the lower part of the washer 20, and a U iron 22 is provided at the lower part of the magnet 21;

[0025] The gasket 12 can provide a gap between the components of the speaker 1 to ensure proper spacing between them. The dust cap 13 can be placed above the diaphragm 14 to prevent dust and impurities from entering the interior of the speaker 1 and protecting the diaphragm 14. The diaphragm 14 will vibrate under the action of the electromagnetic field to produce sound. The bracket 15 is the frame of the speaker 1, used to support and protect the diaphragm 14 and other components. The terminal 16 connects the speaker 1 to the interface of the audio source, usually used to connect wires. The voice coil 17 interacts with the magnet 21 and is a key component for the vibration of the speaker 1. When current passes through the voice coil 17, it is affected by the magnetic field and vibrates. The elastic wave 18 connects the suspension system of the diaphragm 14 and the bracket 15, allowing the diaphragm 14 to vibrate freely while providing a certain restoring force. The auxiliary magnet 19 is usually a component made of iron or magnetic material, which is used to enhance the effect of the magnetic field. The washer 20 is located between the magnet 21 and the voice coil 17, which helps to guide and concentrate the magnetic field.

The U iron 22 is usually a component made of iron or magnetic material, which works together with the auxiliary magnet 19 to generate a magnetic field. The speaker 1 adopts PU edge + carcass for Mylar, which is light in weight. The radiating diaphragm 14 system is used as the sounding body and the coil is used as the driving force. The radiated sound waves are propagated in an omnidirectional manner, which makes the sound field cover a wider range, allowing people to hear more ideal sounds at different angles.
