Vibrating motor with elastic piece with arms and fixing portion fixed to mass block

A vibrating motor, comprising:

• a housing defining an accommodating space,
• a vibrating unit accommodated in the accommodating space,
• an elastic piece elastically suspending the vibrating unit in the accommodating space, and
• a driving assembly fixedly accommodated in the housing;
• wherein the driving assembly is configured to drive the vibrating unit to vibrate;
• the vibrating unit comprises a mass block and a rotor fixed to the mass block;
• the driving assembly is one of at least one driving coil and a magnetic steel assembly;
• and the rotor is the other one of the at least one driving coil and the magnetic steel assembly;
• a first end of the elastic piece is fixed to the mass block;
• a second end of the elastic piece is fixed to the housing;
• the elastic piece and the mass block are integrally formed through stamping;
• wherein the elastic piece comprises a fixing portion stacked on one side of the mass block and two elastic portions;
• the fixing portion is integrally formed with the mass block by stamping;
• the two elastic portions are respectively bent and extended from two diagonal positions of the fixing portion;
• each of the elastic portions comprises a first arm, a second arm, an elastic arm, and a fixing arm;
• each first arm is bent and extended from the fixing portion;
• each first arm is attached to a first side of a corresponding corner of the mass block;
• each second arm is extended perpendicularly from a corresponding first arm;
• each second arm is attached to a second side of the corresponding corner of the mass block;
• each elastic arm is bent and extended from the fixing portion;
• each elastic arm is spaced apart from the mass block;
• each fixing arm is bent and extended from a first end of a corresponding elastic arm away from a corresponding second arm;
• each fixing arm is fixed to the housing;
• a second end of each elastic arm close to the corresponding second arm is fixedly attached to the corresponding second arm;
• two elastic arms are respectively disposed on two opposite sides of the mass block;
• the two elastic portions are symmetrically disposed with respect to a center of the mass block.
