Abstract: A sensory signal output apparatus is provided. The sensory signal output apparatus, includes: a magnetic circuit vibrating in response to an alternating signal flowing through a coil; and an elastic support means elastically supporting the magnetic circuit to surround the circumferential outer surface of the magnetic circuit from one side direction thereof, in which coupling recesses are formed at the circumferential outer surface of the magnetic circuit to be spaced apart from each other, and a coupling piece is provided at a periphery of the elastic support means to be coupled to the coupling recess, the coupling piece is attached to and inserted into the coupling recess. In the sensory signal output apparatus, an elastic support means is inserted into and coupled to a magnetic circuit without using a curling operation to provide easy coupling.

Abstract: The present invention provides a sensory signal output apparatus wherein a coil is disposed in the gap between a magnet/top plate and a yoke, and a portion elastically supported in the free space vibrates in reaction to the magnetic flux generated in the gap in accordance with the direction of the alternating current signal applied to the coil to generate sound and/or vibration, wherein the yoke has a groove formed at a side other than that with the magnet, and the groove has a diameter smaller than that of the magnet, and an inner edge portion with a magnetic fluid. The sensory signal output apparatus of the present invention improves the position retaining force of the magnetic fluid and reduces the deformation of the magnetic fluid, as the magnetic fluid is formed in the edge of the groove of the yoke corresponding to the edge portion of the magnet which has a relatively bigger magnetic force and magnetic field than the plane portion of the magnet.

Abstract: The present invention provides a sensory signal output apparatus, which is constructed such that several frequencies of output can be realized. The sensory signal output apparatus includes a coil (15), to which an alternating signal is transmitted, a magnetic circuit (11) including a magnet (1 Ia), a top plate (1 Ib) and a yoke (1 Ic) to form an opening such that magnetic flux linkage perpendicular to the coil is induced, and a casing (1) receiving the magnetic circuit therein. The sensory signal output apparatus further includes a first vibration unit (10a) having the magnetic circuit, which responds to a magnetic field depending on a direction of the input signal, thus vibrating, and a first vibrating screen (13) adhered or welded to a ring-shaped protrusion of the yoke, thus generating a sensory signal.
