  • Patent number: 4750397
    Abstract: A stringed musical instrument has a plurality of strings stretched between two fixed points and over a bridge. The strings are of substantially circular cross section and made from an elastomeric material such as silicone rubber; all strings are monolithic. The bridge incorporates one or more piezo-electric or other transducers each mounted as a bimorphic element in a simple beam mounting between fixed supports on the bridge and in acoustic contact with the body of the instrument through a resilient baffle pad in contact with the face of the piezo-electric element remote from the supports. That is, mounted in a manner in which the transducer can be considered to be a beam extending between load bearing or supporting members at its two ends, the fixed supports, while it is loaded transversely between its two ends by the baffle pad.
