[0002] Speakers refer to a device that can convert audio signals into sound. In layman's terms, it refers to the power amplifier built into the main speaker box or subwoofer box. After amplifying the audio signal, the sound is played back by the speaker itself to make it louder. Speakers are the terminal of the entire audio system. Their function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the audio system, responsible for converting electrical signals into sound signals for direct human hearing.

[0003] Existing wall-mounted speakers are usually placed on brackets and cannot be adjusted to the optimal sound reception height according to needs.
