摘要： The present disclosure relates to a speaker and a magnetic circuit system thereof. The speaker includes a housing and at least one magnetic circuit system and at least one vibration system arranged in the housing. The at least one vibration system includes at least one layer of drive circuit configured to generate mechanical motion under the action of a magnetic field of the at least one magnetic circuit system, and a diaphragm driven by the at least one layer of drive circuit. The at least one layer of driving circuit is mounted to the diaphragm and has a planar shape. Since the driving circuit of the vibration system has a planar shape, the thickness of the speaker of the present disclosure can be effectively reduced.

摘要： This application provides a speaker and a mobile terminal. The speaker includes a housing and a kernel located in the housing, where there is a front cavity and a rear cavity in the housing, the front cavity is in communication with the outside, and the rear cavity is an isolated cavity. In addition, to reduce a space area occupied by the entire speaker, the front cavity and the rear cavity are disposed in a stacked manner when being disposed. Specifically, the front cavity and the rear cavity are at least partially stacked along a thickness direction of the kernel. Therefore, the rear cavity is disposed in space of the entire speaker in the thickness direction of the kernel, to reduce an area occupied by the entire speaker in the mobile terminal on the premise that a size of the rear cavity meets a requirement.

摘要： Disclosed are a connection structure, and a loudspeaker and electronic device having same. The connection structure comprises a snap ring (11) and a connection column (3). The snap ring (11) is provided with a notch, the width of the notch being larger than the inner diameter of the snap ring (11), and the inner wall of the snap ring (11) being provided with a supporting arm (12). The connection column (3) comprises a column body (31) and a column head (32) located at one end of the column body (31), the outer diameter of the column head (32) being larger than that of the column body (31), and the column body (31) being provided with a snap-in groove (313). The column body (31) of the connection column (3) can pass through the notch in the snap ring (11) and is snap-fitted within the snap ring (11), and the supporting arm (12) of the snap ring (11) can be snap-fitted within the snap-in groove (313) of the connection column (3).
