Vibration motor

A vibration motor comprising:

• a vibration part including a weight and a magnet accommodated in the weight;
• a fixation part including a housing having an accommodation space, a circuit board fixed in the housing, and a coil opposed to the magnet and connected with the circuit board electrically, the housing including an upper cover, a lower cover opposite to the upper cover, and an outer frame forming the accommodation space with the upper and lower covers;
• an elastic connector having for elastically suspending the vibration part in the accommodation space of the housing;
• an anti-drop protective structure arranged on the outer frame and applied to protection of the elastic connector from collision with the housing when the vibration motor drops;
• wherein the outer frame comprises two long side walls which are arranged oppositely and two short side walls which are connected with and opposite to the two long side walls;
• and the anti-drop protective structure is arranged on the short side walls;
• wherein a coil fixation portion for fixing the coils is also arranged on the outer frame and on the long side walls;
• and
• wherein the coil fixation portion comprises bearing walls which extend to the accommodation space in the form of zigzag from the two long side walls respectively;
• the circuit board comprises a first circuit board and a second circuit board which are arranged on the two bearing walls respectively;
• one end of the coil is provided with an anode lead, and the other end thereof is provided with a cathode lead;
• the anode lead is connected with the first circuit board electrically, and the cathode lead is connected with the second circuit board electrically.
