The invention discloses a CD reader capable of preventing the rotating speed of a turntable from being too high. The CD reader comprises a reader body, a rotating cavity is formed in the reader body;a rotating shaft is rotationally arranged on the lower wall in the rotating cavity; the upper end of the rotating shaft extends upwards into the rotating cavity; the rotating shaft is in spline connection with a spline cylinder on the inner and outer circumferences of the rotating cavity; a reading cavity is formed in the upper wall in the rotating cavity in a communicating manner; the upper end of the spline cylinder extends upwards into the reading cavity; and a reading plate is fixedly arranged on the upper end face, located in the reading cavity, of the spline cylinder. According to the invention, the rotating speed of the turntable is prevented from being too high in a manner of stabilizing the rotating speed of the turntable, and meanwhile, the condition of frame dropping during CD reading can be avoided, so that the read video or audio is clear and smooth, is not blocked and distorted, and cannot lose data, and meanwhile, the reading cavity is subjected to heat dissipation treatment, so that a bad reading effect caused by CD overheating during reading is avoided.
Description
technical field [0001] The invention relates to the related technical field of electronic storage devices, in particular to a CD reader which prevents the rotation speed of the turntable from being too fast. Background technique [0002] A CD reader is what we usually call an optical drive. It is a device that reads information from an optical disc. Because the optical disc has large storage capacity, low price, and long storage time, it is suitable for storing a large amount of data, such as sound, image, animation, and video information. , movies and other multimedia information, so the optical drive is an indispensable hardware configuration for multimedia computers. When the reader’s turntable rotates too fast, it is prone to reading frame drop, resulting in unclear and stuck video or audio. , distortion or data loss. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] Technical problem: When ...
