Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal boxes, in particular to a sound amplification box structure used in a narrow space. Background Art

[0002] The sheet metal structure of the traditional sound box is a single-layer sheet metal structure with poor rigidity. After the audio is transmitted, it is easy to cause sheet metal resonance, and the whole box will vibrate. Therefore, it is particularly important to improve the problem of poor rigidity of the sheet metal of the traditional sound box and the vibration of the whole box caused by the sheet metal resonance caused by the audio.
