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.

This invention discloses a switching system for any odd or even number of two or more matched vibrations sensors, such that all possible circuits of such sensors that can be produced by the system are humbucking, rejecting external interferences signals. The sensors must be matched, especially with respect to response to external hum and internal impedance, and be capable of being made or arranged so that the responses of individual sensors to vibration can be inverted, compared to another matched sensor, placed in the same physical position, while the interference signal is not. Such that for 2, 3, 4, 5, 6, 7 and 8 sensors, there exist 1, 6, 25, 90, 301, 966 and 3025 unique humbucking circuits, respectively, with signal outputs that can be either single-ended or differential. Embodiments of switching systems include electro-mechanical switches, programmable switches, solid-state digital-analog switches, and micro-controller driven solid state switches using time-series to spectral-series transforms to pick the order of tones from bright to warm and back.
