A speaker system includes one or more rotating speakers (or speakers with rotating reflectors) that are synchronized in absolute angular position to another rotating speaker or synchronized to audio effects to generated by a signal processing system driving a stationary or rotary speaker. Knowledge of absolute angular position in a multi-rotor speaker array or signal processing system allows for control of rotary position to accomplish acoustic effects otherwise not possible, such as matched-velocity profiles with differential phase control and motion profiles that are not based on simple rotation.

An electronic musical instrument includes a storage unit storing waveform data WD constituted by a plurality of sample values, the waveform data expressing an acoustic waveform of a musical sound emitted from a speaker while a rotor rotates about a rotation axis by a predetermined angle, and a reproduction unit configured to sequentially read out the sample values from the storage unit and generate a musical sound signal based on the read-out sample values, the reproduction unit being configured to change a reproduction speed of the musical sound expressed by the plurality of sample values, without changing a pitch and formant of the musical sound.

A sound capture device is affixed to an acoustic instrument to capture the natural sound output of the instrument. The captured sound signal is routed to an electronic sound augmentation system that is configured to augment the captured sound with spatial sound effects such as reverb, echo, delay, etc. The processed and augmented sound is then reproduced via a vibrating driver that has been affixed to the body of the acoustic instrument. This creates a situation where the body of the musical instrument, responding to a series of vibrations produced by the vibrating driver, acts as a speaker component, reproducing a rich augmented sound output that comprises the sum of the sound produced by the original sound production capabilities of the acoustical instrument plus the added augmented or enhanced sound effects.

An electronic keyboard instrument includes a housing, a keyboard provided in connection with the housing and aligned in a left-right direction of the housing, a sound-emitting component provided inside the housing, and a reflector comprising a reflection surface configured to reflect sound from the sound-emitting component and provided at an upper portion of the housing inside the housing.
