Abstract: A miniature piezoelectric element is conductively mounted on a metal diaphragm having one or two projecting tabs which provide two solderless terminals. An insulating area is screened onto the diaphragm around the piezoelectric element and out onto one tab. A conductive layer is formed on the upper surface of the active element and out onto the insulating area on the tab without contacting the diaphragm. The diaphragm can then be supported within any suitable housing with the tab or tabs projecting for contact by a miniature connector.

Abstract: A mode tracking transducer driver (100) for a non-linear electromagnetic transducer (102) includes a voltage controlled oscillator (104) coupled within a phase lock loop to a transducer driver (106) and a mode detector (112, 108). The voltage controlled oscillator (104) generates a variable frequency output signal, and is responsive to a frequency control signal for controlling the frequency of the output signal. The transducer driver (106) generates a transducer drive signal (502) which is coupled to the non-linear electromagnetic transducer (102) to generate a tactile alert. The mode detector (112, 108) detects a mode change between at least the first operating mode and the second operating mode of the non-linear electromagnetic transducer (102), and in response thereto generates the frequency control signal (118) which establishes a quasi-resonant frequency (204) at which the tactile energy delivered by the non-linear electromagnetic transducer (102) is maximized.

Abstract: A taut armature reciprocating impulse transducer (100) which typically provides a non-linear hardening spring response is adapted to provide a non-linear softening spring response by the addition of magnetic damping elements (106). Two or more taut armature reciprocating impulse transducers (100) can be utilized to produce a mechanical acoustic crossover network (700) which operates to produce a wide frequency response when at least one of the two taut armature reciprocating impulse transducers (100) is adapted to provide a non-linear softening spring response. The mechanical acoustic crossover network (700) allows multiple taut armature reciprocating impulse transducers (100) to be operated together from a signal input. When the mechanical acoustic crossover network (700) is enclosed in a housing (812), the mechanical acoustic crossover network (700) can be operated as a headphone to deliver an audio output.

Abstract: A non-linear reciprocating device (100, 200) includes an armature (12) including non-linear suspension member (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 member (14, 16) for effecting an electromagnetic field in response to the interrupting signal; and a magnetic motion 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).
