摘要： 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.

摘要： An electric acoustic violin is a combination of an acoustic violin and an electric system, and the electric system includes a pickup unit for converting the vibrations of the strings to an electric signal; and a hollow space is formed in the bridge for receiving the pickup unit so that the vibrations are transferred from the strings through the bridge to the pickup unit, whereby the pickup unit faithfully converts the vibrations to the electric signal without any influence of the tension exerted on the bridge by the strings.
