SENSOR-TYPE ELECTRONIC MUSICAL INSTRUMENT BASED ON FREELY MOVABLE LIGHT REFLECTION AND PHOTORECEPTOR SENSOR (PHOTORECEPTOR ELEMENT)

摘要

An objective of the present invention is to provide a system wherein a light source to be converted to music is set, light or a light beam from the light source enters a freely rotatable light reflection plate via an entry aperture, and the reflection plate is controlled so that the entering light is projected upon a photoreceptor sensor (photoreceptor element) keyboard and sound is played. Furthermore, information of this system is digitally converted (3DCG, etc.) and installed in hardware such as a personal computer or a smartphone, such that it is possible to combine and synthesize said information into a signal which is to be converted into an image which is sent from a CCD or CMOS image sensor, run a simulation thereof on a screen, and control a projection of the light or the light beam upon the screen to play a sound or a melody using the reflection upon the photoreceptor sensor keyboard which is connected to the simulated electronic musical instrument.
