Full-bandwidth dual-sided speaker device

A full-bandwidth dual-sided speaker device, comprising:

• a magnetic flux guiding plate;
• a first magnetic circuit module disposed on one side of the magnetic flux guiding plate;
• a second magnetic circuit module disposed on the other side of the magnetic flux guiding plate;
• a first vibration assembly comprising a first bracket, a first diaphragm and a first voice coil, wherein the first bracket is disposed on the magnetic flux guiding plate and is located on an outer side of the first magnetic circuit module, the first diaphragm is disposed above the first bracket and is located on the first magnetic circuit module, and the first voice coil is disposed under the first diaphragm and is disposed within the first magnetic circuit module;
• a second vibration assembly comprising a second bracket, a second diaphragm and a second voice coil, wherein the second bracket is disposed on an outer side of the second magnetic circuit module, the second diaphragm is disposed under the second bracket and is located under the second magnetic circuit module, and the second voice coil is disposed above the second diaphragm and is disposed within the second magnetic circuit module;
• and
• a third vibration assembly comprising a third bracket, a third diaphragm and a third voice coil, wherein the third bracket is disposed on an outer side of the second bracket, the third diaphragm is disposed between the first bracket and the third bracket, the third diaphragm is disposed above an outer side of the second magnetic circuit module, the third voice coil is disposed under the third diaphragm, and the third voice coil is disposed between the second magnetic circuit module and the second bracket, and the first diaphragm and the third diaphragm are staggered and not located on a same plane;
• wherein an extension line perpendicular to a center of the magnetic flux guiding plate is set as a central axial line, and the first vibration assembly, the second vibration assembly and the third vibration assembly are arranged corresponding to the central axial line.
