发明名称 Piezoelectric transducer device for a stringed musical instrument
摘要 A transducer system for a stringed musical instrument having a bridge for supporting a plurality of string saddles, each having a surface for receiving a transducer member of the system. The transducer member is comprised of one or more ceramic crystals supported between conductive strips and encapsulated by an electrically insulating covering. The crystals are responsive to vibrations of the string by way of a spring support insert in the saddle, but the crytals are not directly coupled to the saddle.
