A multifunction vibration actuator is disclosed, which includes a housing
(1) integrally formed with a first house part (1a) with an elliptic wall
(10), a second house part (1b) having a cylindrical wall (11) with a
diameter corresponding to the first house part (1a) at the center of the
ellipse, and both bottom walls (1c) and (1d) of the first housing part
(1a). The actuator also includes an elliptic diaphragm (3) with an
annular voice coil (3) installed on the inner surface thereof, a circular
magnetic circuit part (4), and a disk type suspension (5). The elliptic
diaphragm (3) is tightly installed in the wall of the first house part
(1a), and the circular magnetic circuit part (4) is installed in the
cylinder of the second house part (1b) with the suspension (5).
