Title: Pocket piano
Inventor: HWANG JAY-YEOB
IPC: G10H1/36
Filed: 2009-02-23
Abstract: The invention relates to a pocket piano.  In case of a pocket piano using a small mobile device such as a cell phone, the limitation of the small screen makes it difficult to provide all keyboards of several octave spans as well as dynamics or pedal tones.  Therefore, the invention is directed to resolve these inconveniences.  In one embodiment, a motion sensor is provided to sense a motion.  When a motion is sensed, the display expands, in response to a lateral motion signal, in a lateral direction of keyboards as much as the moving distance; pedal effects are also provided in response to a vertical motion signal.  Every keyboard is given regions with different dynamic levels, thus allowing one to be able to touch a particular region with a desired dynamic level.  With the help of the invention, a player may play the pocket piano even through a small mobile device as if he/she were playing a real piano.
