A contact operation device includes an arm including a contact operation portion at a tip end thereof. The contact operation portion is configured to contact a touchscreen. The contact operation device further includes a support part configured to support the arm. The support part includes a first support mechanism configured to permit the arm to move such that the contact operation portion is carried in a horizontal direction, and a second support mechanism configured to allow the arm to move such that the contact operation portion is carried in a vertical direction.

A uniquely pivotable tonearm stabilized by magnetic fields to achieve superior fidelity during playback, is disclosed. The tonearm comprises a tonearm and an arm wand suspended using two or more torsional elements. A top nut assembly is positioned over a top chassis. The top nut assembly is rotated to provide anti-skating force by rotating counter clockwise. The torsional elements are suspended from the top nut assembly and mounted to the arm wand body as an inverted V configuration. The tonearm further comprises two or more magnets including a ring magnet mounted on a lower chassis body and a pair of cylindrical magnets mounted in the arm wand body. Further, a counterweight is mounted on an end of the arm wand and configured to provide the necessary down-force to balance a cartridge and arm wand during operation, thereby providing improved stability with significant improvement in sound quality.

A tone arm apparatus comprising a hemispherical air bearing in a pivoted tone arm operable on all axes so as to provide a virtually frictionless bearing operative on the tone arm, thereby enabling a stylus and cartridge that converts vibrations in the record groove to electrical signals, to transmit the signals without unwanted bearing noises impacting upon the sound quality of the transmission.

A liquid-bearing tonearm device is configured to read a record on a turntable and comprises a base seat, a liquid tank and a cartridge assembly. The liquid tank is mounted at the base seat, disposed over the turntable, elongated along a linear direction, and has a containing chamber containing working liquid. The cartridge assembly floats on the liquid tank through a floating piece and has a stylus portion and a counterweight portion. The liquid-bearing tonearm device is used with the turntable to play music. A cartridge is assembled to the stylus portion and contacts grooves of the record to read vibrations and signals. When the turntable spins the record, the cartridge assembly floats in the liquid tank and is moved along the linear direction with the cartridge pulled inwardly by the record. So, a contacting angle between the cartridge and the grooves remains parallel, thereby enhancing reading quality.

To implement stable sound playback with high sound quality, a record player for playing back sound recorded on a phonograph record includes a rotator that rotates the phonograph record, a container arranged on a side of the rotator and capable of storing one of a liquid, powder, and gel, a float to be floated on the one of the liquid, the powder, and the gel stored, in a standstill state, in the container, an arm extended from the float in a direction of the rotator, and a phono cartridge attached to the arm and including a sound playback stylus.

A static electricity elimination floating tonearm includes a tonearm base, a tonearm, a deflector and an ion air-pressure device. An air-floating arm tube extends horizontally from a side of the tonearm base, a top edge of the air-floating arm tube is provided with air holes arranged at intervals, the tonearm includes a floating piece and an arm rod, and the ion air-pressure device is provided for generating an airflow with positive and negative ions which is sent into the changer of the air-floating arm tube and blown out from the air holes of the air-floating arm tube, the floating piece together with the arm rod are blown upward to define an air-floating state, and deflected by the floating piece and the deflector and blown towards the turntable, not only providing a frictionless air-floating displacement state of the tonearm, but also eliminating static electricity and dust on the turntable.
