摘要： An efficient kinetoelectric transducer is provided for use in a phonograph playback system. The transducer is positioned in the forward end portion of the pickup arm and includes a first electrode, an electret member oriented contiguous to the first electrode, and a second electrode juxtapositionally oriented relative to the side of the electret opposite that of the first electrode. The second electrode, which has a stylus support means attached thereto, is oriented to facilitate a degree of controlled vibratory movement relative to the electret member. A holding means retains the electrodes and intermediate electret member to effect a unitized transducer structure from which the stylus support member protrudes.

摘要： A phonograph pickup cartridge which has a stylus with a pair of driving arms engageable with the ends of a pair of tapered flexible members and formed with tapered openings therein so that the movement of the stylus moves the flexible members and causes the volume of the air chambers therein to vary. A pair of electrostatic transducers are coupled to the cavities of the flexible members and have diaphragms which vary with variations in volume of the flexible members so as to produce audio output signals.

摘要： Provided are a vibration unit which includes a pair of right and left coils that vibrate in response to vibration of a stylus attached to a cantilever and a magnetic circuit which includes a magnet and a pair of yokes and forms a magnetic path. The coils to be disposed in a gap between the pair of yokes are flat coils having perfect circular shapes, and V-shaped notches are formed on opposing surfaces, with the coils interposed therebetween, of the pair of yokes 4. An intersection angle of the V-shaped notch is set to be an angle to allow channel separation between right and left output signals to be obtained by the pair of coils to be equal to or larger than 20 db.

摘要： A pick-up cartridge for a gramophone record comprises a cartridge shell in which is mounted a stylus assembly including a short, rigid stylus arm and a resilient wire which is much shorter in length than the arm and is attached to the rear end of the arm in alignment with a rear straight part of the arm. Transducer means responsive to movement of the arm are located ahead of the resilient wire and the wire is attached at its rear end to a mounting member supported in the cartridge shell so that the stylus assembly extends forwardly and downwardly away from the cartridge shell. A stylus tip attached to the stylus arm adjacent the forward end thereof is located in the vicinity of the axis of the straight part of the arm.

摘要： An electret transducer is described which includes an electret formed from a relatively thin elongated body of electrically insulating dielectric material which is polarized for establishing a residual electrostatic field within the body. First and second relatively thin elongated bodies of electrically conductive material are positioned adjacent opposite surfaces of the electret body and extend substantially coextensively with the electret body. The conductive bodies thereby sandwich the electret and provide electrodes for the transducer. This sandwich configuration is formed into a convolute shaped transducer assembly and includes electrical conductors which are coupled to each of the electrodes and between which a transducer output signal is provided upon mechanical excitation of the convolute shaped transducer assembly. The transducer thus provided comprises a displacement transducer which advantageously can be employed in acoustical detection and reproduction systems.
