[0002] A speaker is a device that can convert audio signals into sound. It usually refers to a speaker mainframe or subwoofer box with a built-in power amplifier, which amplifies the audio signal and plays it back by the speaker itself, making the sound louder. When the speaker is placed in a fixed position, it has a better sound effect in the area where the speaker is pointed, while the sound effect in other positions is poor.

[0003] The existing speaker angle adjustment usually requires manual rotation of the entire speaker. There are also some speakers that can rotate automatically. The speakers are driven by a motor to rotate, and only the horizontal angle of the speakers can be adjusted. It is inconvenient to adjust the arc of the speakers, and it is also inconvenient to adjust the height of the speakers at multiple angles at the same time. The use effect is not ideal. Therefore, a multi-angle rotating directional speaker that can propagate sound in a direction is proposed. Utility Model Content
