Patent number: 9245509Abstract: 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 into a memory for each of the keys. 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. In response to an operation of a key, a sound board vibration waveform corresponding to the operated key is read out from the memory, and the excitation device is driven in accordance with the read-out waveform signal so that the sound board is vibrated.Type: GrantFiled: December 3, 2013Date of Patent: January 26, 2016Assignee: YAMAHA CORPORATIONInventors: Yuji Fujiwara, Shinya Koseki, Fukutaro Okuyama

Patent number: 8878045Abstract: An acoustic effect impartment apparatus detects striking of any one of strings by a corresponding hammer in an acoustic piano like a grand piano, and vibrates a vibration section with a driving waveform signal obtained by synthesizing sine wave signals of the fundamental frequency and harmonic frequency of the hammer-struck string. Such vibration of the vibration section is transmitted to the keys via a soundboard and bridge of the piano. Thus, vibration is excited in the hammer-struck string by the striking with the hammer but also by the driving waveform signal, so that an acoustic effect corresponding to the driving waveform signal is imparted. Because the driving waveform signal is a simple signal using the sine wave signals corresponding to the fundamental frequency of the string, a natural feeling of the acoustic piano will not be lost even when the acoustic effect is imparted.Type: GrantFiled: September 14, 2012Date of Patent: November 4, 2014Assignee: Yamaha CorporationInventors: Shinya Koseki, Fukutaro Okuyama
