Abstract
An electric contrabass has a bridge structure on a body in which an inner space is defined, and the body is further formed with a slit under the bridge structure so that the lid of the body vibrates like a cantilever; a vibration sensor is provided inside the body, and has a vibration sensitive surface held in contact with the lower surface of the lid; while a player is bowing the strings, the vibrating strings excite the lid through the bridge structure, and the vibrations of the lid is converted to an electric signal through the vibration sensor; since the distance from the vibrating strings and the single vibration sensor is approximately equal, the single vibration sensor produces the electric signal without undesirable imbalance and interference.
Claims19
An electric stringed musical instrument for producing electric tones, comprising;
- a musical instrument including
- a body structure formed with an inner space and having a vibratory portion partially defining said inner space said body structure allowing a of vibratory portion to vibrate widely relative to a remaining portion of said virbratory portion,
- a bridge structure standing on a surface said vibratory portion, and
- plural strings stretched over said body structure across said bridge structure and independently exciting said bridge structure during vibrations thereof, and
- an electric system including
- only a single vibration sensor connected to another surface of said vibration portion reverse to said surface and monitoring said part of said vibratory portion so as to produce an electric signal representative of said vibrations and supplied to a sound system,
- where said sound system produces said electric tones as a function of said electric signal.
An electric stringed musical instrument for producing electric tones, comprising:
- a musical instrument including
- a body structure formed with an inner space and having a vibratory portion partially defining said inner space and having a slit so as to permit a part of said vibratory portion to vibrate widely relative to a remaining portion of said vibratory portion,
- a bridge structure standing on a surface of said vibratory portion, and
- plural strings stretched over said body structure across said bridge structure and independently exciting said bridge structure during vibrations thereof;
- and
- an electric system including
- a vibration sensor connected to another surface of said vibratory portion reverse to said surface and monitoring said part of said vibratory portion so as to produce an electric signal representative of said vibrations.
