Pianoforte instrument exhibiting an additional delivery of energy into the sound board, and method for influencing the sound of a pianoforte instrument

摘要

Disclosed is a pianoforte instrument comprising a musical mechanism with keys. Also provided are strings which are struck via a mechanism when the keys are actuated and are made to vibrate. The vibrations of the strings are transmitted to a sound board. A device is provided for delivering additional oscillating energy into the sound board. Also provided are sensors which directly or indirectly detect actuation of the keys of the musical mechanism. The measured values of the sensors are fed to a sound-amplifying device. The sound-amplifying device is equipped with units which compile data corresponding to a desired characteristic sound in accordance with the measured values of the sensors. The sound amplifying device supplies the sound board with additional oscillation energy via the delivering device according to the determined data.
