Abstract: A stringed musical instrument includes: a musical instrument body configured such that a string is attached thereto; a pickup configured to: i) detect vibration of the string and ii) output a string vibration signal according to the vibration; a detection sensor that is: i) attached to the musical instrument body and ii) configured to output a detection signal according to a force applied to the musical instrument body; and a controller that is attached to the musical instrument body, and is configured to output, based on the detection signal, a control signal configured to control an operation of an effector configured to impart an effect to the string vibration signal.

Abstract: An information processing system includes an information acquirer configured to acquire input information including finger information relating to a finger of a user playing a string instrument and an image of a fretboard of the string instrument and sound information of sound of the string instrument played by the user, and an information generator configured to generate fingering information indicative of fingering by processing the acquired input information using a generation model that learns a relationship between training input information and training fingering information.

Abstract: An instrument comprises a body including a soundboard that transmits a vibration of a sound source, and a vibration exciter configured to vibrate the soundboard in response to an input signal. The vibration exciter comprises a vibrator member attached to the soundboard and configured to vibrate the soundboard in response to the input signal, a displacement member configured to displace relative to the vibrator member in response to the input signal, and a support member including an elastic member and supporting the displacement member via the elastic member with respect to the body. At least part of the vibration exciter overlaps a center of a region of the soundboard that extends in a width direction from a contact region of the soundboard where the soundboard contacts with the vibrator member.

Abstract: Provided is an acoustic apparatus capable of causing a sensation that a sound is produced in a larger space than reality, without requiring an excessive cost and time-consuming installation. The sound collected by a microphone is converted to an electrical signal, and a reflected sound component is extracted by a signal processing portion. The reflected sound component thus extracted is amplified by an amplifier, and the reflected sound component thus amplified vibrates transducers attached to a back-side board surface of each acoustic structure, whereby reflected sound is emitted from all faces including front-side board surface and the back-side board surface. A player can thus naturally perceive as if the space where he stays is expanded.

Abstract: The musical instrument includes: a pickup that acquires an electric sound signal corresponding to a sound performed on the musical instrument; effector circuitry that imparts an effect to the acquired electric sound signal; a vibrator that produces mechanical vibration corresponding to the effect-imparted sound signal; and a transmission device that transmits the mechanical vibration, produced by the vibrator, to the body of the musical instrument with a characteristic having a fundamental frequency region of the musical instrument suppressed. The electric sound signal corresponding to the performed sound is imparted with an effect, the vibrator is driven by the effect-imparted sound signal, and a mechanical vibration sound is generated from the body of the musical instrument. The thus-generated mechanical vibration sound is audibly generated from the body as a vibration sound additional to the performed sound, which allows a user to experience a performance feeling that has never existed before.
