摘要： An electro-mechanical filter is configured from a single thin metal sheet and comprises a base portion, at least four vibratory tines extending outwardly from the base portion, and a plurality of supporting members also extending outwardly from the base portion. The tines and supporting members are arranged circumferentially around the base portion in alternate relationship and extend from the base portion in parallel with each other. The tines may extend in either the same or the opposite direction as the supporting members. A piezo-electric element is coupled to each tine and the elements are differentially connected together to form a filter.

摘要： Herein disclosed is a reed type electromechanical filter device which comprises a vibrator element having a pair of spaced parallel arm portions adapted to vibrate in lateral directions, a pair of piezoelectric ceramic plates or electromechanical transducer elements mounted on the arm portions of the vibrator element, and a pair of elastic metal members respectively mounted on the outer side faces of the arm portions and/or a pair of elastic metal members respectively mounted on the inner side faces of the arm portions. The elastic metal members are effective to prevent the arm portions from directly striking against each other and/or the inner faces of side walls of a housing enclosing the vibrator element in the event the filter device is subjected to a violent impact which would otherwise cause deterioration of the performance quality of the filter device.

摘要： A band-pass filter comprises a resonator system having a first and a second resonator coupled together by a coupling mass resiliently suspended on supporting means, the first resonator being associated with an electrodynamic transducer capable of converting an input signal into oscillation energy, and the second resonator being associated with an electrodynamic transducer capable of generating an output signal corresponding to the oscillating condition of said second resonator.

摘要： A torsional fork transducer wherein the two lines of the fork are interconnected at their feet by a piezoelectric crystal operating in the longitudinal mode, the crystal being energized at a rate determined by the natural frequency of the fork to effect torsional vibration of the tines. Oscillators derived from a pick-up electrode on the crystal are applied to the input of an electronic amplifier whose output is fed to a drive electrode on the crystal to sustain the fork in vibration.
