摘要： The tone arm holder includes a saddle with a hook portion that defines an open end. A resilient dividing member is located on the top surface of the saddle. The space between the resilient dividing member and the hook define a lock seat configured and arranged for frictional engagement, receipt and storage of a tone arm therein. The opposing side of the saddle from the resilient member defines a performance seat configured and arranged for freely supporting a tone arm whereby a tone arm may be placed on and removed from the performance seat without frictional engagement of the tone arm to the holder. The tone arm is freely movable between the performance seat at a first position and the lock seat at a second position by traversing across the resilient dividing member by exceeding the resilient force of the resilient dividing member.

摘要： A record player capable of playing phonographic records that may be played in a scratch style by a user. The record player includes a tonearm that is rotatably supported at or near an end of the tonearm by a structure having both horizontally and vertically fastening points to the tonearm. The fastening points are configured to receive a user activated tension adjustment element. A user may advance or retreat the tension adjustment element to selectably control the positioning, or relative tension in the tonearm such that any record skipping due to undesirable tonearm pressure is controlled, or to achieve a specific sound.

摘要： 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.
