A magnetic phonograph record stabilizer is configured to hold a phonograph record in a biased contact against a turntable. The stabilizer features a base which is engaged with a magnetic housing which is moveable from a first position where magnetic attraction biases the base toward the turntable. The magnetic housing is slidable to a second position eliminating the biasing from the magnetic flux so the stabilizer can be removed from the turntable.

A phonograph record player including a speaker enclosure within the record player that is mechanically insulated from the phonograph components to reduce vibrations from the speakers to the phonograph components. One or more coupling mechanisms are used that absorb, reduce, and/or minimize vibrations generated by components coupled to a secondary housing, such as speakers, from being transmitted to a primary housing that includes a turntable.

An audio device includes a base portion a power supply circuit arranged on the base portion and configured to output electric power; a rotation body rotatably supported by the base portion and configured to, upon rotation of the rotation body, move a playback point of a piece of music; an electric circuit arranged on the rotation body; and a non-contact power feeding mechanism configured to supply in a non-contact manner the electric power output by the power supply circuit to the electric circuit in which the non-contact power feeding mechanism is arranged on a path from the power supply circuit to the electric circuit.

In some embodiments, a record stabilizer is configured to fit both common size spindle holes (e.g., as commonly found in 12 singles or LPs) and larger hole types (e.g., as commonly found in 7 45 rpm singles, typically referred to as 45s). In some embodiments, the stabilizer achieves this functionality using one side that is substantially flat (for common size spindle holes) and another side with a built-in adapter to protrude into larger spindle holes. In some embodiments, the record stabilizer also serves as an adapter, e.g., allowing 45s to be played on turntables with common size spindles without using any other adapter.

A platter supported and driven turntable has a spindle, an upper circular platter, a lower circular platter, an arm board, and a tonearm assembly. The spindle is to rotate about a first direction. The spindle has a hub, a shaft and a bearing assembly between the hub and the shaft. The shaft has a flange. The upper circular platter is attached to the shaft of the spindle. The lower circular platter is attached to the flange of the shaft of the spindle. The arm board is attached to the hub of the spindle. The arm board has a first extension section, a mid-range section, and a second extension section. The mid-range section of the arm board is disposed between the upper circular platter and the lower circular platter. The tonearm assembly is directly attached to the first extension section of the arm board. The second extension section of the arm board is attached to a ballast or a supporting turntable through one or more adjustable height mounts.
