A vibrating apparatus (200) comprises a vibrating element (202), electromagnetic coils (204, 206), driver circuits (210, 212), and a controller (208) coupled to the electromagnetic coils (204, 206) through driver circuits (210, 212). The vibrating element (202) has a first end fixedly mounted to a housing (106) and a second end having a permanent magnet (216) attached thereto. The electromagnetic coil (204) is positioned adjacent to the permanent magnet (216), and the electromagnetic coil (206) is positioned adjacent to the permanent magnet (216) on a side opposite the electromagnetic coil (204). The controller (208) generates signals to the electromagnetic coils (204, 206) through the driver circuits (210, 212) for producing magnetic fields around the electromagnetic coils (204, 206), where the magnetic fields attract and repel the permanent magnet (216) such that the vibrating element (202) vibrates at its resonating frequency.
