The monitoring unit is secured on the base, and includes a light emitter, an image capturing module and a processing module. The light emitter can emit light toward the platter or an acoustical record disposed on the platter. The image capturing module can receive the light reflected by the platter or the acoustical record, and capture images of the platter or the acoustical record. The processing module can receive the images from the image capturing module, and determine a current rotating speed of the platter or the acoustical record by analyzing and comparing the images captured by the image capturing module at successive time points."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Record player","description":"A record player includes a base, a platter, a tonearm assembly and a monitoring unit.
