摘要： The present disclosure discloses a sounding device including a frame, a magnetic circuit system with a magnetic part and a vibration system. The vibration system includes a diaphragm fixed to the frame, a voice coil driving the diaphragm to vibrate and arranged around the magnetic part, and a metal shrapnel with conductive function. One end of the metal shrapnel is fixed to the frame and electrically connected to an external circuit, and the other end of the metal shrapnel is fixed to the voice coil and electrically connected to the lead wire of the voice coil. The metal shrapnel restrains a movement of the voice coil in a direction perpendicular to a vibration direction of the diaphragm. Compared with the related art, the sounding device disclosed by the present disclosure can reduce the number of elements to simplify the product structure.

摘要： A coaxial double-sided speaker device includes a frame, first and second vibration units fixed to two opposite sides of the frame, a magnetic circuit unit, and a front cover fixed to the frame and provided under the first diaphragm. The first vibration unit includes a first diaphragm fixed to the frame and a first voice coil. The second vibration unit includes a second diaphragm fixed to frame and a second voice coil. The front cover and first diaphragm are spaced apart to form a first front cavity. The frame is provided with a sound leading channel including first and second openings respectively toward the first and second diaphragms. The first opening communicates with the first front cavity. The second opening is located at periphery of the second diaphragm. The double-sided speaker device has a higher volume, a smaller product size and a higher utilization rate of the magnetic circuit unit.
