Abstract:
A vibration motor includes a housing; a vibration unit accommodated and suspended in the housing, the vibration unit including a first vibrator having a first resonant frequency, and a second vibrator having a second resonant frequency; a first elastic member having one end fixed to the first vibrator and another end fixed to the housing for suspending the first vibrator in the housing; and a second elastic member having one end fixed to the second vibrator and another end fixed to the housing for suspending the second vibrator in the housing. By virtue of the configuration, the vibration motor is capable of working at two different resonant frequencies.
