Patent ID: 7285713

Claim:
An electric stringed musical instrument for electrically producing tones, comprising: a stringed musical instrument including a body structure having a longitudinal direction and lateral direction, a bridge held in contact with a major surface of said body structure and formed with a groove, and at least one string stretched over said major surface in said longitudinal direction and held in contact with said bridge so that vibrations thereof are propagated to said bridge; and an electric system including a pickup unit connected to said bridge for converting said vibrations to an electric signal, and including: a vibration sensing element made in the form of film held in contact with a major surface of said bridge extending between end surfaces both held in contact with said major surface of said body structure and said at least one string, the vibration sensing element being sensitive to a component force of said vibrations in said longitudinal direction, and another vibration sensing element accommodated in said groove, physically independent of said vibration sensing element and sensitive to another component force of said vibrations in said lateral direction, so that said electric signal is produced from a signal component of said vibration sensing element and another signal component of said another vibration sensing element, said electric signal being representative of said component force and said another component force.
