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.
