Abstract
The utility model discloses an improved portable loudspeaker box, comprising a box body, loudspeakers, a button circuit board, an interface circuit board, a power supply, and a passive board. The box body comprises a fixing frame formed by relatively splicing a front half frame body and a rear half frame body, an outer shell covering on the outside of the fixing frame, a top plate arranged in the upper end of the fixing frame, and a bottom plate arranged in the lower end of the fixing frame. The outer shell is formed by relatively splicing a front half shell and a rear half shell. The front half frame body is provided with through holes matched with the loudspeakers. The loudspeakers are fixedly mounted on the through holes by fixing seats. The rear half frame body is provided with an opening matched with the passive board. The passive board is fixedly mounted on the opening. An enclosed resonant sound cavity is formed between the loudspeakers and the passive plate. The loudspeaker box described by the utility model is compact and reasonable in structure, relatively excellent in sound quality and effect, good in stability, convenient to assembly, and easy for processing and producing.
