1. A speaker, comprising:
a first frame;
a second frame relatively fixed with the first frame;
a first vibration system supported on a side of the first frame distal to the second frame, the first vibration system comprising a first diaphragm and a pair of first voice coils connected with the first diaphragm and driving the first diaphragm to generate sounds, the pair of first voice coils arranged spaced apart from each other in a first direction, the first direction perpendicular to a vibration direction of the first diaphragm, a winding plane of each first voice coil parallel to the vibration direction of the first diaphragm;
a second vibration system supported on a side of the second frame distal to the first frame, the second vibration system comprising a second diaphragm and a pair of second voice coils connected with the second diaphragm and driving the second diaphragm to generate sounds, the pair of second voice coils arranged spaced apart from each other in a second direction, the second direction perpendicular to a vibration direction of the second diaphragm, the first direction perpendicular to the second direction, a winding plane of each second voice coil parallel to the vibration direction of the second diaphragm; and
a magnetic circuit system located between the first frame and the second frame.
