Latest Patents

Mantani's latest patents focus on enhancing the functionality and sound quality of keyboard instruments. One of his inventions involves a system where, in response to the operation of a key, a drive signal indicating a sound waveform is supplied to an excitation unit on a soundboard. This setup allows the soundboard to vibrate in response to mechanical vibrations generated by the excitation unit, producing an actively-vibrated-soundboard sound along with an acoustic effect from the vibration propagation to a string. The excitation unit features a voice coil that is designed to optimize the drive force for exciting the soundboard, resulting in improved responsiveness in high-frequency ranges.

Another patent describes a sound generation mode where a drive signal with a frequency characteristic corresponding to the operated key is supplied to the excitation unit. This design ensures that the soundboard vibrates to generate acoustic vibrations that correspond to the key pressed. The excitation unit is supported in a way that minimizes the load on the soundboard, allowing for better vibration characteristics and sound quality.
