摘要： A bifunctional turntable which includes a rotating shaft, a platter, a light sensor module, an audio control module, and a plinth is revealed. The rotating shaft which is driven by a power source to rotate drives the platter to rotate. Then the light sensor module disposed on the rotating shaft detects rotation speed of the platter for playing a record at normal speed. The audio control module is located in the plinth and disposed on a simulated record for detecting changes in the simulated record which is manually operated. Then the audio control module sends signals to a digital audio control system at a rear end for driving the digital audio control system to output audio signals. Thereby the present turntable plays not only vinyl records but also simulated records.

摘要： The design of the gramophone (100) for playing music recordings on vinyl records (50) which rotate on a levitating turntable (10) with the help of magnetic forces, substitutes all established versions of analogue gramophones, where the drive and rotation of the turntable are predominantly provided by an electric motor and mechanical elements. The technology of the turntable (10), rotating and levitating on magnetic forces, does not require changing the other elements of the analogue gramophone device, however, its advantage is that it reduces the unwanted vibrations of the turntable (10) and its unsteady rotation while playing music. In this way the accuracy and credibility of the sound readings is improved. Additionally, the need to push the turntable stylus (32) more strongly on the vinyl record (50) is reduced, otherwise required due to the possible skipping of the stylus (32). Thus the format of the sound recording in the groove of the vinyl record (50) is maintained for a longer period of time, as well as the sharpness of the turntable stylus (32). To ensure steady rotation, the excess inertia mass of the turntable (10) is no longer required. In addition to the benefits in sound processing, the new technology also upgrades the level of the visual experience when listening to audio artistic creations. The system of the levitating and rotating turntable can also be used for other purposes, such as to display products in showroom windows and similar.

摘要： 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.

摘要： A platter supported and driven turntable has a spindle, an upper circular platter, a lower circular platter, an arm board, and a tonearm assembly. The spindle is to rotate about a first direction. The spindle has a hub, a shaft and a bearing assembly between the hub and the shaft. The shaft has a flange. The upper circular platter is attached to the shaft of the spindle. The lower circular platter is attached to the flange of the shaft of the spindle. The arm board is attached to the hub of the spindle. The arm board has a first extension section, a mid-range section, and a second extension section. The mid-range section of the arm board is disposed between the upper circular platter and the lower circular platter. The tonearm assembly is directly attached to the first extension section of the arm board. The second extension section of the arm board is attached to a ballast or a supporting turntable through one or more adjustable height mounts.

摘要： A record player includes a base including a front surface, a plinth including a front surface, a platter, and a tone arm. The base includes a base height, a base width, and a base depth, with the base height being the shortest dimension and the base width being the greatest dimension. The plinth is mounted atop the base and connected to a motor housed within the base. The plinth includes a plinth height, a plinth width, and a plinth depth, the plinth height being greater than the plinth width. The platter is rotationally mounted to the front surface of the plinth so that a diameter of the platter is nearly vertical above the base. The tone arm is secured to the front surface of the base.

摘要： An optical disk system comprising a turntable (56) adapted for contact with a CD-disk (6) and having a motor-driven shaft. The system includes an optical unit (10) for projecting a laser beam onto the surface of the CD-disk and detecting laser light reflected back to the unit after it has been modulated with information stored on the disk. The turntable and the motor-driven shaft are supported for rotation by an air journal unit to facilitate the work of the drive motor and to reduce mechanical disturbances.

摘要： An automatic disc loading apparatus for an information reproducing or recording/reproducing system in which pieces of information recorded on a record disc are to be reproduced or pieces of information are recorded on a record disc and thereafter reproduced. The apparatus comprises a casing structure into which the record disc is to be inserted in a predetermined direction along a predetermined plane substantially parallel with the predetermined direction toward a predetermined position within the casing structure. The casing structure is formed with a slot elongated in a direction substantially perpendicular to the aforesaid predetermined direction. A disc guide is provided comprising a pair of disc guide members movable toward and away from each other within the casing structure and in the neighborhood of the above mentioned slot substantially symmetrically with respect to the above mentioned predetermined direction. The record disc is passed between the disc guide members when being inserted in the predetermined direction into the casing structure through the slot. A drive is operative to drive the disc guide members for movement toward or away from each other.

摘要： The spindle of a turntable body comprises a top member having a projection to be fitted in a center hole of a phonograph record, and a generally cylindrical spindle body partially received in a cylindrical bearing. The top member has a turntable mount, whose outer diameter is greater than the projection, and a plurality of a radial passageways are made therein, which passageways communicate with a vacuum source. The lower end of the spindle body, which is made of two elements of different material so that machining is easy, is closed in one embodiment so as to be supported on a relatively small ball bearing. A spindle body having an open end is used in another embodiment. The ball bearing may be replaced with a pointed end of the spindle body. Means for tightening the air seal around a lubricant in the cylindrical bearing is provided for isolating the lubricant from the moving air lead to the vacuum source. A turntable sheet for attracting differently sized records to the turntable is provided with radial and circular grooves on both sides, and may be placed on the turntable body.
摘要翻译： 转盘体的主轴包括顶部构件，该顶部构件具有配合在留声机记录的中心孔中的凸起，以及部分地容纳在圆柱形轴承中的大致圆柱形心轴体。 顶部构件具有其外径大于突起的转台安装座，并且在其中形成多个径向通道，该通道与真空源连通。 在一个实施例中，由不同材料的两个元件制成的主轴体的下端使得机械加工容易闭合，以被支撑在相对较小的滚珠轴承上。 在另一实施例中使用具有开口端的心轴主体。 滚珠轴承可以用主轴体的尖端代替。 提供用于将圆筒形轴承中的润滑剂周围的密封件紧固的装置用于将润滑剂与运动空气引导线隔离到真空源。 用于将不同大小的记录吸引到转盘的转盘在两侧设置有径向和圆形的凹槽，并且可以放置在转盘体上。
