PURPOSE: A sensation signal output device is provided to prevent collision with a case and noise due to interference and abrupt feature variation, by providing whole vibration force due to a reciprocating motion. CONSTITUTION: A sensation signal output device(10) has a magnetic circuit including a top plate and a magnet vibrating by reacting with a first coil(11). A first and a second leaf spring are fixed to both sides of the magnetic circuit in a vibration direction. The first and the second leaf spring have a symmetric structure performing contraction and expansion motion to each other. A second coil changes current flow according to an alternating signal applied from an external signal source. The second coil is wound around the outer circumference of a pipe type bobbin(12). |
