A vibration motor comprising: a housing providing a space having a top surface, a bottom surface and walls in which the following elements are accommodated: a first resilient member fixed to the bottom of the housing is adapted to apply a resilient force toward the top of the housing to which the second resilient member is fixed, and a second resilient member fixed to the top of the housing is adapted to apply a resilient force toward the bottom of the housing to which the first resilient member is fixed; a first yoke (31; 33) and a second yoke (35; 39) coupled to the first resilient member and the second resilient member, respectively, the first and second yokes being located at the center of the resilient members defined by the axis of symmetry of the housing a magnetic body to create a magnetic field toward the center thereof, the magnetic body being attached to a top end of the first yoke; and a coil to which a current of a predetermined frequency is applied in use, wherein the coil is provided on the bottom surface of the second yoke and positioned in the center where the magnetic field is created, said vibration motor being characterised in that the damping characteristics are adjusted by differently setting the gaps (gap1, gap2) between the first yoke and second yoke and the inner wall of the housing. a housing providing a space having a top surface, a bottom surface and walls in which the following elements are accommodated: a first resilient member fixed to the bottom of the housing is adapted to apply a resilient force toward the top of the housing to which the second resilient member is fixed, and a second resilient member fixed to the top of the housing is adapted to apply a resilient force toward the bottom of the housing to which the first resilient member is fixed; a first yoke (31; 33) and a second yoke (35; 39) coupled to the first resilient member and the second resilient member, respectively, the first and second yokes being located at the center of the resilient members defined by the axis of symmetry of the housing a magnetic body to create a magnetic field toward the center thereof, the magnetic body being attached to a top end of the first yoke; and a coil to which a current of a predetermined frequency is applied in use, wherein the coil is provided on the bottom surface of the second yoke and positioned in the center where the magnetic field is created, a first resilient member fixed to the bottom of the housing is adapted to apply a resilient force toward the top of the housing to which the second resilient member is fixed, and a second resilient member fixed to the top of the housing is adapted to apply a resilient force toward the bottom of the housing to which the first resilient member is fixed; a first yoke (31; 33) and a second yoke (35; 39) coupled to the first resilient member and the second resilient member, respectively, the first and second yokes being located at the center of the resilient members defined by the axis of symmetry of the housing a magnetic body to create a magnetic field toward the center thereof, the magnetic body being attached to a top end of the first yoke; and a coil to which a current of a predetermined frequency is applied in use, wherein the coil is provided on the bottom surface of the second yoke and positioned in the center where the magnetic field is created, said vibration motor being characterised in that the damping characteristics are adjusted by differently setting the gaps (gap1, gap2) between the first yoke and second yoke and the inner wall of the housing.
