The Innovation of Oscillators in Rhodes pianos

Abstract

For decades, the enchanting sounds of mechanicalelectric keyboards have been a source of inspiration. However, there has been a lack of significant innovation in their mechanical components for many years. This paper deals with development of oscillators for mechanical-electric keyboard instruments, specifically focusing on innovations in a frequency spectrum due to modifications in the geometry of mechanical parts, variations in materials, sensing position and hammer strike position. Drawing from the original oscillators of Rhodes Mk7 instrument, new virtual models were created using software SolidWorks and subsequently analyzed using software Ansys. These models were then physically fabricated and subjected to examinating. The final assessment involved comparing the frequency spectra of the upgraded assemblies with the original assemblies and analyzing resulting data.
