Problems solved by technology

However, tones are sometimes produced by acoustic instruments in a complex environment in which the working state and operation timing of the keyboard and pedals of the instrument affect the tones, yet known electronic keyboard instruments are limited in reproducing the tones produced in such a complex environment
This leads to inadequate performance

Abstract

An electronic keyboard musical instrument capable of performing fine soundboard vibration control based on outputs generated individually for each transducer, thereby realizing natural sound reproduction with sufficient volume and easy tone quality adjustment. The soundboard is fixed on the frame, and the transducers are spaced apart from each other and installed on the soundboard. Based on the first and second performance signals generated in response to key operations of the keyboard and damper pedal operations, drive signals for the transducers are respectively generated in consideration of the characteristics and installation positions of the transducers, and the drive signals are supplied to the transducers . The soundboard is thereby caused to vibrate at a frequency that varies according to the pitch, thereby producing musical tones and / or damper tones.

Description

technical field [0001] The present invention relates to an electronic keyboard musical instrument having a soundboard that is vibrated to produce musical tones. Background technique [0002] Improvements have been made to electronic keyboard instruments in order to faithfully reproduce the diffuse, natural tones produced by acoustic instruments. However, electronic keyboard instruments still sound a little different than acoustic instruments. [0003] Specifically, when an operator such as a key is actuated, the acoustic musical instrument produces not only a musical sound produced by the vibration of a vibrating member such as a string but also a sound produced by components of the musical instrument in contact with each other. The resonance of the soundboard and other instrument components also produces sound. Moreover, the aforementioned various sounds complexly interact with each other to generate further sounds. On the other hand, existing electronic keyboard instrum...
