Provided is a vinyl record system, including: a turntable; a tone arm; a platter; a microcomputer executing OCR and DVS software; I / O ports; and an image sensor. Names of songs saved as digital music files on a portable memory storage device are typed or written onto a label. The label is stuck onto a timecoded DVS vinyl record mounted onto the platter. The image sensor captures an image of the label. OCR software extracts a text string from the image. The microcomputer identifies digital music files stored on the portable memory storage device corresponding with the songs based on song names included in the text string and loads them into the DVS software. The DVS software maps the digital music files to a signal map of the timecoded DVS vinyl record and plays them back according to a location of a needle of the tone arm on the signal map.

The utility model relates to a phonograph, and discloses a precision fine tuning singing arm phonograph, comprising a placing box, the inner wall of the placing box is fixedly connected with a box body, the top outer wall of the box body is rotatably connected with a singing arm, the top outer wall of the box body is provided with an adjusting mechanism, the adjusting mechanism comprises a fixing plate, and the fixing plate is fixedly connected with the box body. The bottom of the fixing plate is fixedly connected to the outer wall of the top of the tone arm, the top of the fixing plate is fixedly connected with a supporting rod, the top end of the supporting rod is fixedly connected with a sliding rail, the outer wall of the sliding rail is slidably connected with a sliding block, and the inner wall of the sliding block is slidably connected with a limiting plate. According to the utility model, by rotating the elliptical wheel, the projection of the elliptical wheel extrudes the limiting plate and drives the sliding block to slide on the sliding rail, so that the horizontal position of the singing arm is changed, the playing requirements of different records can be met, and after adjustment is completed, the magnetic attraction block and the magnetic attraction groove attract and fix the singing arm to prevent the singing arm from moving due to vibration during playing.
