RECORDING AND REPRODUCTION OF WAVEFORM BASED ON SOUND BOARD VIBRATIONS

摘要

In a musical instrument, such as a piano, having a sound board, the sound board vibrates in response to vibrations of a string responsive to depression of a key. A waveform corresponding to such vibrations of the sound board is detected and recorded. The recorded vibration waveform is usable for reproduction of a sound based on sound board vibrations. In a sound reproduction apparatus, such as a piano, having a sound board, an excitation device physically excitable in response to an input waveform is provided on the sound board. A signal indicative of a vibration waveform of the sound board is received, and the excitation device is driven in accordance with the received waveform signal so that the sound board is vibrated. Thus, a sound based on the sound board vibrations can be replicated or reproduced with a high quality.

主权项

1. A musical instrument comprising;
at least one performance operation key; at least one sounding member each provided in association with one of said at least one performance operation key; a sound board; at least one striking member each configured to physically vibrate one of said at least one sounding member in response to an operation of said at least one performance operation key; a transmission joint disposed in such a manner as to physically transmit vibrations of said at least one sounding member to said sound board; a vibration waveform detector configured to detect a vibration waveform corresponding to vibrations of at least one of said sound board and said transmission joint; and a controller configured to perform control for storing, into a memory, a time series of the vibration waveforms detected by said vibration waveform detector in correspondence with a music piece or phrase performed using said at least one performance operation key.
