    • The digital sound playback device (10) of the present invention includes a physical interface that closely simulates an analog scratch turntable. The digital sound playback device (10) includes a motor (30) that directly drives a hollow spindle (36). A platter (14) is connected to the hollow spindle (36). A center spindle (18) is routed through the hollow spindle (36) where the rotational axis of the hollow spindle (36) is co-axial with the rotational axis of the center spindle (18). A full-size vinyl LP record (16) is removably connected to the center spindle (18). Digital encoders (82, 84) are used to respectively detect the rotational speed and direction of the platter (14) and the center spindle (18) to respectively create a platter and center spindle control signal. The control signals are used by a central control processor (100) to determine how the digitized audio should be modified. As a result, a digital audio file can be scratched in similar fashion to an analog vinyl record on an analog turntable.
    • 本发明的数字声音播放装置(10)包括紧密模拟模拟刻划转盘的物理接口。 数字声音播放装置(10)包括直接驱动中空心轴(36)的马达(30)。 盘片(14)连接到中空心轴(36)。 中心主轴(18)穿过中空心轴(36),其中空心心轴(36)的旋转轴线与中心心轴(18)的旋转轴线同轴。 全尺寸乙烯基LP记录(16)可拆卸地连接到中心主轴(18)。 数字编码器(82,84)用于分别检测盘片(14)和中心主轴(18)的旋转速度和方向,分别产生一个盘片和中心主轴控制信号。 控制信号由中央控制处理器(100)使用以确定如何修改数字化音频。 结果,数字音频文件可以以与模拟转盘上的模拟乙烯基记录类似的方式被划伤。
