The Dynamic Vibration Absorber Principle, Applied to High-Quality Phonograph Pickup
Recent developments in phonograph disc recording have placed increased demands on the playback transducer. Both dynamic range and bandwidth have been extended, particularly on discrete four-channel records. The dynamic vibration absorber principle is studied as a means of extending transducer bandwidth without compromising other parameters. An application of the vibration absorber is developed for use in a top quality magnetic phono pickup that provides high performance through almost five decades of frequency.
