Abstract: Disclosed is a moving-coil loudspeaker, comprising a vibration system and a magnetic circuit system located below the vibration system. The vibration system comprises a vibrating diaphragm, a spider, and a voice coil that are combined from top to bottom. The vibrating diaphragm comprises a vibrating diaphragm body with a surround, and a vibrating diaphragm reinforcing portion incorporated in the central position below the vibrating diaphragm body. The vibrating diaphragm reinforcing portion comprises a first layer of electrically conductive material, the spider comprises a second layer of electrically conductive material, and the vibrating diaphragm reinforcing portion is bonded to and conducts with the spider by an electrically conductive adhesive. The magnetic circuit system comprises a central spring washer, a central magnet, and a magnetically conductive yoke combined together from top to bottom. The first layer of electrically conductive material and the second layer of electrically conductive material serve as a movable plate, and the central spring washer, the central magnet and the magnetically conductive yoke serve as a fixed plate, thus forming a capacitor structure for detecting the vibration displacement of the moving-coil loudspeaker. With the capacitor structure provided by the present invention, the vibration displacement of the moving-coil loudspeaker can be monitored.

Abstract: The present invention relates to a speaker, and speaker module. The speaker comprises a housing and two electrical connection members mounted on the housing, each electrical connection member comprises a second pad portion exposed from a side wall of the housing, and the second pad portion is disposed in parallel to the side wall of the housing. The speaker further comprises a circuit board attached to the side wall of the housing, and the circuit board is electrically connected to the second pad portions. The speaker of the present invention enables attaching the circuit board to the side wall of the housing, thus increasing operation space, and reducing operational risks. By attaching the circuit board to the side wall of the housing, the present invention reduces interference of the circuit board on a terminal antenna, and reduces the possibility of the circuit board involving in vibration of a back chamber, thus improving the performance of the speaker. Meanwhile, by providing the circuit board on the side wall of the housing, the present invention simplifies the shape of the circuit board, thus providing a compact layout, and accordingly saving costs.
