摘要： 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.

摘要： The present invention discloses a speaker module and a sound production device. The module comprises a module shell and a speaker unit mounted in the module shell. The module shell comprises a shell main body and two fixed pole plates connected fixedly on the shell main body. The two fixed pole plates are insulated from each other, and each of the two fixed pole plates has a connecting portion exposed to the outside of the shell main body. A vibration system of the speaker unit is provided with a movable pole plate, and each of the two fixed pole plates together with the movable pole plate form a variable capacitor. The speaker module is configured to output an electrical signal representing a vibration displacement of the vibration system by the connecting portions of the two fixed pole plates.
