Apparatus, systems and methods for use in imparting linear tonearm tracking for a record player are provided. The systems can include a joint member having three separate movable connections to a tonearm, guiding slot and slidable pivot base, wherein a rear pivot location of the tonearm is on the slidable pivot base. A movement of the tonearm can cause the joint member to adjust a position of the slidable pivot base, as a function of a configuration of the guiding slot, and this combination of interactions is combined to impart substantial linear tracking for the tonearm.

The present invention relates to a headshell and a tonearm, which are parts of an audio turntable, and, more particularly, to a headshell and a tonearm configured such that, in connection with a swingarm-type audio turntable, the groove of an LP record can be accurately read. According to an embodiment, in connection with a headshell that connects a cartridge and a tonearm, there is provided a headshell and a tonearm for mounting a cartridge of an audio turntable, comprising a joint portion that enables the cartridge, which has been coupled, to rotate on a horizontal plane.

A motion inducing system for playing sounds over a gramophone is provided. An electrical signal such as that from a digital music player is converted to lateral movement of a surface using a linear motion transducer. The lateral movement moves the stylus of a gramophone, and the music from the digital music source is played through the horn of the gramophone.

A playback device (measurement device) in a record playback system including a record player and the playback device measures a frequency characteristic of each of a plurality of input signals which are input from the record player to the playback device when a plurality of test signals for measuring a characteristic of the record playback system are played back by the record player, the plurality of test signals being recorded on a phonograph record, the plurality of input signals corresponding to the plurality of test signals recorded; calculates a measurement error between the frequency characteristic of each of the plurality of input signals measured and a predetermined frequency characteristic; selects a frequency characteristic of which the measurement error is smallest from among the frequency characteristics of the plurality of input signals, as a measurement result of the record playback system; and outputs the measurement result selected.
