A moving-magnet type pickup cartridge is disclosed, which includes a cantilever, a stylus chip attached to a front end part in a longitudinal direction of the cantilever, a damper disposed at a base end part in the longitudinal direction of the cantilever and configured to support the cantilever in a swingable manner, a magnet disposed in the longitudinal direction of the cantilever and immediately above the stylus chip at the front end part of the cantilever, and configured to vibrate with vibration of the stylus chip, and a yoke formed in a U-shape, having generating coils being wound thereon, and having magnetic poles at both leg parts thereof being disposed to face the magnet. With this configuration, there is provided a moving-magnet type pickup cartridge enables not only to ensure a large output signal but also to obtain a faithfully reproduced sound with little distortion.

The invention relates to a vinyl record player automatic stop and lift tonearm structure. The vinyl record player includes a turntable for placing a record and a base for installing a tonearm. The base includes an inner shaft portion arranged thereon. The tonearm includes a rotating shaft portion correspondingly assembled on the inner shaft portion. The base includes a sensor provided on the inner shaft portion. The tonearm includes a magnetic element arranged on a circumference of the rotating shaft portion and corresponding with the sensor. The base includes a bracket assembled thereon for installing the tonearm. The bracket has a central shaft connected to an electromagnetic unit and an elastic member. The electromagnetic unit is electrically controlled to drive the bracket down to link the tonearm, and the electromagnetic unit to release the bracket and use the compression force of the elastic member to lift the bracket.

Computing systems and methods for estimation and correction of audio pitch variations resulting from eccentric rotation in the playback of phonograph records are disclosed. The methods include simulation of phonograph playback to generate eccentric and non-eccentric time bases for correction. Estimation of eccentricity parameters is done by a parameter optimization through evaluation of a spectral sharpness detection function on time-spectral content of audio data. Candidate audio data are generated using phonograph simulation while conducting an optimal parameter search. The disclosed technology further provides systems and methods to correct audio using such parameters to correct the induced pitch variations from eccentric phonograph record playback in order to improve the pitch stability of audio recordings. In addition, the physical properties of groove radius and playback speed variations in phonograph playback may be estimated from the eccentric record playback.
