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 (1Ia), a top plate (1Ib) and a yoke (1Ic) 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. The sensory signal output apparatus further includes a second vibration unit (10b), which is vibrated by the coil, which repels and thus vibrates relative to the magnetic circuit, thus generating a sensory signal.
