Abstract: A vibrator for producing a sensible vibration synchronized with an electric signal which drives a speaker includes a casing having plural concavities provided in an inner wall thereof, a cylinder, a coil wound around the cylinder, a magnetic pole having an annular gap of such a required breadth as to have the coil inserted thereinto without contacting with the magnetic pole, and rubber elastic bodies securely provided in the concavities, and wherein the cylinder is fixed to the casing so that the coil is inserted into the gap, and magnetic pole is supported to the casing at its periphery by the rubber elastic bodies in such a manner to be radially and centrally displaceable and to be rotatable in the casing.When current flows to the coil to generate a magnetic force, the magnetic pole displaces radially and rotates and then stops the radial displacement and rotation thereof to thereby provide a static state.
