Abstract: A speaker includes: a frame, a vibration system fixed to the frame, including a diaphragm fixed to the frame and a voice coil driving the diaphragm to vibrate and emit sounds, and a magnetic circuit system fixed to the frame, wherein the diaphragm includes a dome and a suspension surrounding and connected with the dome, the dome includes a first metal dome with a through hole and a second dome covering the through hole, the first metal dome is located between the suspension and the second dome, and the first metal dome is fixedly connected with the suspension and the second dome. Compared with the related art, the speaker disclosed by the present disclosure has higher high frequency performance.

Abstract: The present disclosure discloses a sound device comprising: a metal frame; a vibration system fixed to metal frame; a magnetic system fixed to metal frame driving the vibration system to vibrate; the magnetic system includes a lower clamp plate, a main magnet fixed to the side of the lower clamp plate near the vibration system, and a sub-magnet set around the main magnet and spaced apart from the main magnet to form a magnetic gap; the sound device also includes a location pin fixed to the lower clamp plate, the location pin is formed on the circumference of the lower clamp plate by injection molding, and the end of the location pin away from the lower clamp plate is attached to the metal frame to form a positioning of the metal frame. The present disclosure can make the lower clamp plate positioned with the metal frame through the location pin, thus avoiding the problem that the lower clamp plate cannot be positioned with the metal frame.

Abstract: The present disclosure provides a sounding device, which includes a frame, a vibration system fixed on the frame and a magnetic circuit system for driving the vibration of the vibration system. The magnetic circuit system includes a magnet unit fixed on the frame and a magnetic yoke connected to the magnet unit. The sounding device also includes a plastic sealer to form multiple leak holes. The plastic sealer is opened to replace the existing breathable spacer. The sounding device of the present disclosure has smooth leakage, good acoustic performance and good user experience.

Abstract: The present invention provides a speaker box, includes a housing having an accommodating space, a speaker unit accommodated in the accommodating space of the housing, and a sound channel formed in the accommodating space. The speaker unit includes a diaphragm that vibrates sound. The diaphragm divides the accommodating space into a front sound cavity and a rear cavity. The sound channel communicates the front sound cavity with an outside and is connected with the front sound cavity to form a front cavity. The sound channel includes a first sound channel communicating the front sound cavity with the outside and two second sound channels communicating with the front sound cavity and the first sound channel. The second sound channels are respectively disposed at opposite sides of the first sound channel.
