A steering apparatus according to an aspect of the present disclosure includes a rim member, a center member connected to a steering shaft at a rotation center of the rim member, a first sound output apparatus provided on a front surface of the rim member or the center member, and a first rim chamber unit provided in the rim member and in communication with a space behind the first sound output apparatus.

Apparatus and associated methods relate to acoustic-electric sensor system including a main acoustic sensor operably coupled to detect string vibrations of an acoustic-electric instrument and a feedback suppression acoustic sensor configured to primarily detect sound board vibrations of the acoustic-electric stringed instrument at a location with a substantially attenuated string vibration signal relative to its sound board vibration signal. In an illustrative example, a mixing circuit may at least partially cancel out sound board vibration signatures output by the main and feedback suppression acoustic sensors with one another to produce a mixed output signal. The feedback suppression acoustic sensor may be spaced outside of an ellipse substantially centered around a sound board string coupling point. The main acoustic sensor may be arranged in close proximity to receive the string vibration signal. The mixed output signal may substantially reject audio feedback disturbances while retaining the unique characteristic sound of the instrument.

A musical instrument includes: a musical instrument body configured to reverberate by vibrating at least one vibrating member in accordance with a performance operation; a pickup configured to output a performance information signal corresponding to the performance operation; a microphone disposed in a vicinity of the musical instrument body and configured to output a sound collection signal corresponding to sounds around the musical instrument body; and a vibrator configured to vibrate the musical instrument body based on the performance information signal and the sound collection signal.

A system for remotely generating sound from a musical instrument includes a calibration system to improve the quality of the sound produced by the musical instrument. In one embodiment, the system includes an input configured to receive a signal representative of the sound of a first musical instrument, an exciter for converting the signal to mechanical vibrations, a coupling interface for coupling the mechanical vibrations into a second musical instrument, and a calibration system for altering the signal sent to the exciter.

A keyboard musical instrument includes a string-striking mechanism (hammer), driver, sound receiver, analyzer, and adjuster. The hammer strikes a string responsive to a change in position of an associated key of keyboard. The driver drives the hammer under a driving condition in accordance with control data. The sound receiver generates an audio signal corresponding to a sound occurring in the vicinity of the hammer. The analyzer detects the hammer striking a string by analyzing the audio signal generated when the hammer operates. The adjuster adjusts the control data in accordance with results of the analysis. The analyzer detects hammer striking a string in accordance with an intensity of the audio signal occurring within a search range, which has a predetermined relationship along a time axis with regard to a time at which the hammer commences operation.
