The Innovation of oscillators in mechanical-electrical keyboard instruments
Prokop, Šimon ; Buzzi, Mario (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with innovations of oscillators of mechanical-electric keyboard instruments, especially from the perspective of frequency spectrum innovations. On the basis of the original oscillators of the Rhodes Mk 7 instrument, innovative virtual models of these oscillators were created in SolidWorks, which were subsequently analyzed in Ansys. Subsequently, these assemblies were physically fabricated and tested. In the final evaluation, the signal spectra of the upgraded assemblies were compared with the original tone and the analyzed data. The theoretical part of the thesis also discusses basic signal processing methods and describes methods for evaluating sound perception using psychological acoustics.
