Abstract
A pickup unit is used for converting vibrations of strings to electric signals for producing electric tones at good loudness, and the pickup unit includes a bridge assembly stationary to a body of the stringed instrument, vibration-responsive piezoelectric elements secured at the end portions thereof to the bridge assembly and vibration mediators held in contact with the strings and exerting force on the other end portions of the piezoelectric elements; since the vibration mediators have the freedom to move in the direction of the bending in the bridge assembly, the electric signals exactly represent the vibrations of the strings.
Claims32
A pickup unit for a stringed musical instrument, comprising:
- a stationary member attached to a body of said stringed musical instrument, and having plural zones;
- plural transducers connected at certain portions thereof to said stationary member in said plural zones, respectively, and deformable in response to repeated forces respectively exerted thereon in certain directions for producing electric signals representative of said repeated forces;
- and
- plural vibration mediators connected between strings of said stringed musical instrument and other portions of said plural transducers for transmitting said repeated forces from said strings to said plural transducers, and having a freedom to move in at least said certain direction in said plural zones, respectively.
