The disclosure pertains to a scratch effect controller for use by a disk jockey, wherein at least one electromagnet creates the slippage tension or friction effect between the user manipulated disc, which includes a vinyl-like surface thereby simulating a vinyl record, and the rotatable or fixed platter. The strength of the electromagnet is variable so as to create a variable slippage tension or friction effect.

An apparatus for enhancing media playback on a turntable, such as an audio record turntable, includes an illumination apparatus. The illumination apparatus is generally placed on the turntable's platter, beneath a record to be played. The record may be transparent or semi-transparent. The illumination apparatus includes a light source that projects light up through the record for producing a visual effect.

A turntable that has a platter that can be vertically positioned so that the VTA between the stylus of the cartridge and the record can be easily adjusted without tweaking or touching the tone arm. The turntable includes a base, a platter, a spindle assembly configured to position the platter above the base, and a spindle adjustment mechanism configured to selectively position the vertical position of the platter with respect to the base. In one embodiment, the spindle adjustment mechanism includes a drive shaft that is configured to engage the spindle assembly and to selectively drive the spindle assembly up or down. As the spindle assembly is moved up and down, the platter moves up and down with respect to the base. In another embodiment, the spindle assembly includes a spindle shaft configured to rotate inside a chamber of the spindle assembly. A bolt which attached to the spindle shaft is configured to move up and down when the spindle shaft is rotated. The platter, which supported by a ball bearing resting on the bolt, moves up and down with the bolt as the spindle shaft is rotated. With either embodiment, a remote control unit or a mechanical crank can be used to move the platter up or down with respect to base to adjust the VTA without touching or tweaking the tone arm.

An improved turntable is described with inherent properties for reducing noise generated by external sources or by the parts of the turntable. The plinth of the turntable is comprised of an elastomeric layer and at least one stiffening layer that adds rigidity to the plinth. The support feet, spindle bearing, and armboard only come into contact with the elastomeric layer, which dampens energy, allowing the turntable produce the audio on the record without excessive noise.

The turntable platter configuration of the present invention includes a groove on the platter edge about its periphery to allow for an improved ergonomic finger control for a DJ to alter the speed of the platter rotation. The turntable platter configuration also includes a regularly spaced shape about the periphery of the platter to be used with a strobe for allowing the user to ensure the rate of the rotation is at the appropriate speed, such as 33 RPM or 45 RPM.

A record player includes a turntable, a drive motor, a non-contact transmission mechanism, a tone arm, and a housing. The non-contact transmission mechanism includes a drive-side rotor and a magnetic member. The drive-side rotor is rotated by a driving force of the drive motor. The drive-side rotor is formed of a permanent magnet. The magnetic member is constituted of a soft magnetic body. The turntable is rotated according to the rotation of the drive-side rotor by an attraction force acting on the magnetic member from the permanent magnet.

The present invention relates to a combined record player, wherein analog audio players are positioned on a top portion or a side portion of a cabinet, a digital audio player is positioned on a front portion of the cabinet, a first PCB is positioned on a front portion or a bottom portion of the cabinet, a second PCB is positioned on a rear portion of the cabinet, and an analog audio output interface is positioned on a rear surface of the cabinet; the first PCB contains an analog-to-digital signal converter, the second PCB contains a digital-to-analog signal converter, the analog audio players are electrically connected to the analog-to-digital signal converter, the digital audio player is electrically connected to the digital-to-analog signal converter, the analog-to-digital signal converter is electrically connected to the digital-to-analog signal converter, and the digital-to-analog signal converter is electrically connected to the analog audio output interface. The invention can integrate the analog audio players and the digital audio player within a cabinet where electrical wires between components in the cabinet do not interfere with each other and keep neat, and both the first PCB and the second PCB have a larger heat dissipation space.

A system including a phonograph record implement having a phonograph record with a plurality of grooves operable for recording audio data. A record player device is configured to read the audio data contents of said phonograph record implement. A wheel appliance moves or rotates on said phonograph record implement to produce an audio signal and a needle appliance reads or translates a plurality of grooves to an audio signal as the record player device moves around the stationary phonograph record. A speed control switch is operable for selecting at least one preset speed from a plurality of varying preset speeds for said record player device to operate. A wireless transmitter, which transmits the audio signal to an external receiver, which receives the audio signal produced from said stationary phonograph record for listening remotely.

The present invention relates to a record player with a cabinet, a speaker, a movement base-plate, and a movement, wherein the cabinet contains a first opening and a second opening, the first opening being positioned on a side surface, a bottom surface or a top surface of the cabinet, and the second opening being positioned on the top surface of the cabinet; the speaker is positioned at the first opening and is electrically connected to the movement; and the movement base-plate is positioned at the second opening and includes a recessed part in which the movement is placed. The record player of the present invention includes a built-in speaker and a good resonance chamber formed therein, therefore the sound quality played by the record player can be effectively improved.
