Vinyl record player automatic stop and lift tonearm structure
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.

Record player with repeatable playback
The present invention relates to the technical field of record players, and in particular, to a record player with repeatable playback, including a fixing base; and a tone arm body, a tone arm shaft, a circuit control assembly, a lifting and sliding mechanism, and a horizontal swinging mechanism that are disposed on the fixing base respectively. An upper end of the tone arm shaft is connected to one end of the tone arm body, and the tone arm shaft is rotatably disposed on the fixing base. The circuit control assembly includes a support frame; and a control circuit board, an encoder component, a rotating arm positioning component, and an induction gear that are disposed on the support frame. A gear transmission structure is disposed on one side, close to the gear, of the rotating arm positioning component.
LIQUID-BEARING TONEARM DEVICE
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.
