Electronic device

An electronic device comprising:

• a housing having an accommodation groove;
• a first magnetic module comprising a first magnetic component and a second magnetic component, wherein the first magnetic component and the second magnetic component are arranged in parallel in the accommodation groove, the first magnetic component and the second magnetic component both have two surfaces, and each of the first magnetic component and the second magnetic component has a first magnetic pole and a second magnetic pole on the two surfaces, respectively;
• a counterweight base disposed on the first magnetic module;
• a motor coil disposed on the counterweight base, wherein inner sides beneath the motor coil corresponds to the first magnetic pole of the first magnetic component, and outer sides beneath the motor coil corresponds to the second magnetic pole of the second magnetic component;
• a supporting plate disposed on the motor coil;
• a second magnetic module disposed on the supporting plate, wherein the second magnetic module comprises a major magnetic component and a minor magnetic component, the minor magnetic component is located on one side of the major magnetic component, the major magnetic component and the minor magnetic component both have two surfaces with the first magnetic pole and the second magnetic pole, the second magnetic pole of the major magnetic component corresponds to an upper part of the motor coil belonging to an inner side, and the first magnetic pole of the minor magnetic component corresponds to the other side the upper part of the motor coil belonging to an outer side;
• a bracket module disposed in the housing and on the second magnetic module;
• a vibration module disposed on the bracket module;
• and
• a voice coil disposed under the vibration module and passing through the bracket module, wherein the voice coil is located inside the second magnetic module.
