The inside of the upper cover is fitted with a speaker. The improvements include a blow-molded spring; one end of the blow-molded spring is connected to the upper cover, and the other end is connected to the lower cover in rotating mode; inner wall of the upper cover is provided with a buckle, and a buckle flute is arranged in a position on the lower cover corresponding to the buckle. A blow-molded spring connects the resonant sound unit and speakers into one piece so as to avoid the flaws such as poor sound effects and narrow volume range of pure resonant sound unit or conventional compact sound unit. Music of different sound quality may be given with superior sound quality effects. The portable vibration speaker is characterized by its compactness, handiness and superior bass effects, and may meet the needs of young consumers. |
