Abstract: The present invention provides a speaker including a first frame, a second frame, a first vibration system, a second vibration system, and a magnetic circuit system. The first vibration system includes a first diaphragm and a pair of first voice coils. The second vibration system includes a second diaphragm and a pair of second voice coils. The pair of first voice coils is arranged spaced apart from each other in a first direction. The pair of second voice coils is arranged spaced apart from each other in a second direction. The first and second directions are perpendicular to a vibration direction of the first diaphragm. The first direction is perpendicular to the second direction. Winding planes of the first and second voice coils are parallel to the vibration direction. The speaker of the present invention has strong anti-swing ability and can save space in the height direction.
