Description

Technical Field

[0001] The utility model relates to a sound box shell guide mechanism, belonging to the technical field of loudspeaker products. Background Art

[0002] Speakers are included in speaker products. Speakers generally include speaker shells. Most speaker shells include an upper speaker shell and a lower speaker shell. The upper speaker shell and the lower speaker shell are installed together. In order to ensure the rapid installation of the upper speaker shell and the lower speaker shell, a guide mechanism is generally used to quickly align the upper speaker shell and the lower speaker shell.
