摘要： Provided is a speaker, including a frame; a vibration unit fixed to the frame; and a magnetic circuit unit driving the vibration unit to vibrate and provided with a magnetic gap. The vibration unit includes a diaphragm fixed to the frame and a voice coil inserted in the magnetic gap to drive the diaphragm to vibrate and produce sound; an outer periphery of the diaphragm bends and extends to form at least one fixing portion; and the at least one fixing portion extends along a vibrating direction of the diaphragm and is attached to an inner peripheral side of the frame. With this structure, the bonding strength of the frame and the diaphragm is improved, the diaphragm does not occupy an outer space of the frame, and an appearance size of the speaker is effectively controlled, thereby facilitating the miniaturization design.

摘要： Provided is a speaker box, including a housing having receiving space and a sounding unit received in the housing. The housing includes a plastic member and a reinforced rigid body fixed to the plastic member by injection molding. The plastic member includes a bottom wall connected to the reinforced rigid body and a blocking wall connected to the bottom wall. The speaker box further includes a solder terminal electrically connecting the sounding unit to an external circuit. The solder terminal includes a main body portion, first and second electrical connection portions. The plastic member further includes an enclosure extending from the bottom wall away from the reinforced rigid body. The enclosure is separated from the blocking wall by a distance and encloses the main body portion. The enclosure and the reinforced rigid body are bonded by glue. The speaker box has low costs, simple assembly and high assembly stability.

摘要： Provided is a speaker box, including housing and sounding unit having diaphragm including vibration portion and suspension portion. The housing includes holder, lower and upper covers. The holder includes holder body, holder extension portion and holder fixing portion. The sounding unit is fixed to the holder fixing portion. Orthographic projection of the vibration portion completely falls into the holder body. The suspension portion is arc-shaped formed by recessing away from the holder body. The lower cover includes lower cover plate and lower cover sidewall. The sounding unit, the holder and the lower cover sidewall define front sound cavity. The sounding unit and the lower cover define rear sound cavity. The lower cover sidewall, the holder fixing portion, the holder extension portion and the upper cover define auxiliary rear sound cavity communicated with the rear sound cavity. The speaker box has large cavity volume and good acoustic performance.
