Description

Rotary tuning sound box Technical Field The utility model relates to the technical field of sound equipment, in particular to a rotary tuning sound box. Background A sound box refers to a device that converts an audio signal into sound. In popular terms, the power amplifier is arranged in the main box body of the sound box or the bass box body, and after the audio signal is amplified, the sound is played back by the sound box, so that the sound is amplified. The loudspeaker is the terminal of the overall sound system and functions to convert audio electrical energy into corresponding acoustic energy and radiate it into space. It is an extremely important component of sound systems, which is responsible for the task of converting electrical signals into acoustic signals for direct listening by a person's ears. Patent document CN222602521U discloses a portable sound box, which comprises a first half shell, a second half shell and a control board arranged on the first half shell, wherein the control board is provided with a first fixing structure and a second fixing structure, the inner shell wall of the first half shell is provided with a first limit structure and a second limit structure, a first limit space is formed between the first limit structure and the second limit structure, the inner shell wall of the second half shell is provided with a third limit structure, the third limit structure is provided with a second limit space, and the first fixing structure is inserted into the first limit space and the second fixing structure is inserted into the second limit space, so that the control board is fixed between the first half shell and the second half shell.
