Image Number 6 for United States Patent #7692346.

A compact enclosed type vibrator capable of ensuring a large amount of vibration has a casing (5), a coil (10) and a magnetic circuit unit (11) provided in the casing, and a suspension (3) supporting the magnetic circuit unit. The magnetic circuit unit has an extent in the radial direction and has an outer peripheral surface set adjacent to the inner peripheral surface of the casing across an annular gap. At least one of the casing and the magnetic circuit unit is provided with a vent passage (13a and 13b) that additionally communicates between a first space (17) and a second space (18) formed at the upper and lower sides of the magnetic circuit unit.
