The invention relates to tonearm tracking mechanisms in phonograph players and mechanical devices constructed for the purpose of reproducing or playing back recorded audio material previously impressed, in the form or grooves, onto a surface of a disk, which are commonly called phonograph players or turntables. Such disk is commonly called, among other similar words, a phonograph record or a vinyl disk. The present invention is a tangential tracking tonearm mechanism, wherein the tonearm bearing subassembly has two rotary bearings in the lateral plane and a coupling linkage built into a compact subassembly. The collective contribution of these elements, when properly configured and appropriately adjusted, make, during playback of audio material on a disk, reduced playback distortion over radial tracking mechanisms and closely mimics the conditions under which nearly all masters are made.

A customized music recording, selection and playback system providing a convenient means for storing hundreds to thousands of songs on a single system, which provides immediate access to any of the songs in a convenient, easy to operate manner. This audio entertainment system can store audio sound recordings, or even segments of a sound recording selectively, not merely store collections of existing media. The system can use any audio source, digital or analog, for the audio content. The system replaces boxes of phonograph records, boxes of cassette tapes, cases of CDs, and a plurality of musical pieces (or “songs”), by storing all audio information in one chassis. The system is continuously reconfigurable; songs can be added or removed at any time. The system efficiently stores audio information, using a digital audio compression system that preserves near compact disc quality but achieves a large reduction in the size of the stored digital audio information. The compression system is particularly effective for stereo recordings, i.e. two channels of audio corresponding to the conventional dual microphones used in music recording. Thus, many more songs could be stored on the system at a given time.

An improved tone arm mounting system, for improved damping of tone arm system (100) vibrations. Tone arm system (100) is supported by tone arm pedestal (106). Adjuster screw (301) is affixed to the bottom of tone arm pedestal (106) so that adjuster screw axis of revolution (309) passes through or near tone arm system weight center of gravity (310). Adjuster screw (301), by threaded means, rotatably receives adjuster wheel (302), which is thin and is large in diameter, for easy access to its outer edge for manual or mechanical operation. Rotation of adjuster wheel (302) on adjuster screw (301) changes the height of tone arm pedestal (106) and thereby changes VTA (110).

The tone arm system (100) is supported by arm board (206) without vertical connection to arm board (206) thereby damping mechanical vibrations and improving signal quality. A lightly loaded vibration damping washer (306) can be used between thrust bushing (307) and adjuster wheel (302) to damp or filter transfer of mechanical vibrations from tone arm system (100) to arm board (206) and back into tone arm system (100).

Systems and methods are disclosed relating to electro-mechanical devices and related computer control and audio processing systems intended to optimize playback fidelity of phonograph records. Said recordings are manufactured by a process that employs a cutting head assembly driven in a straight path from the outer to the inner-most radius of the recordable surface. However, most record turntables device that are used to play back phonograph records rely on a stylus transducer attached to the end of a pivoting arm. Instead of the linear path followed by the original cutting head, said tonearm traces an arc across the surface of the recorded disk resulting in playback distortion proportional to error in alignment of said stylus relative to the tangent of the groove. This invention addresses this deficiency and produces an optimal audio quality of playback of phonograph records.

The Present Invention is for a speaker system both standalone and in a phonograph that greatly reduces sympathetic vibration and feedback due to interaction of sound vibration transmitted from bass speakers to the chassis. The solution is twofold. First, the speakers are mounted in a substantially airtight enclosure. Second, the substantially airtight enclosure is suspended within the sound system chassis using elastic members in tension. A typical elastic member is an extension spring. In a phonograph, the elastic suspension almost completely isolates vibrations of the speaker enclosure from the phonograph chassis, thereby drastically reducing sympathetic vibration and feedback, and accommodating new depths of bass extension.
