Abstract
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.
