Abstract
A non-linear reciprocating device (100, 200) includes an armature (12) including non-linear suspension members (14, 16); a compliant contactor (50, 72), coupled to a power source (BT), and further coupled to the armature (12) for generating an interrupting signal; an electromagnetic driver (25), coupled to the non-linear suspension members (14, 16) for effecting an electromagnetic field in response to the interrupting signal; and a magnetic motional mass (18) suspended by the non-linear suspension members (14, 16), and coupled to the electromagnetic field for generating a reciprocating movement of the magnetic motional mass (18) which is transformed through the non-linear suspension members (14, 16) and the electromagnetic driver (25) into tactile energy. The compliant contactor can be either a single pole compliant contactor (50) or double pole compliant contactor (72).
