Abstract
A record player includes a base, a platter, a tonearm assembly and a monitoring unit. 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.
Claims12
A record player for playing an acoustical record, said record player comprising:
- a base;
- a platter rotatably mounted on said base and configured to support the acoustical record thereon;
- a tonearm assembly pivotally mounted on said base and configured to read the acoustical record for producing sound stored by the acoustical record;
- and
- a monitoring unit secured on said base, and including
- a light emitter configured to emit light toward said platter,
- an image capturing module configured to receive the light reflected by said platter and to capture images of said platter, and
- a processing module configured to receive the images of said platter from said image capturing module, and to determine a current rotating speed of said platter by analyzing and comparing the images captured by said image capturing module at successive time points.
