ABSTRACT:
In the construction of a pickup mechanism for electric pianos, the bridge is mounted on a vibration transmitter plate of minor acoustic transmission loss and coupled to the piano plate via vibration absorbers and the pickup unit for converting acoustic vibrations into corresponding electric signals is arranged in direct contact with the transmitter plate or in contact with an intervening vibration amplifying component such as a leaf spring locally attached to the transmitter plate. Damping characteristics, especially the envelope of the tone sustain curve, is made very close to that of the natural sounds generated by non-electric pianos thanks to the damping effect and enriched sensitivity in pickup, and replacement of components out of order can be practiced very easily and simply.
