Abstract:
1. A pickup device for sounds from a stringed instrument having in a main body a top plate provided with a bridge supporting one or more strings, said top plate used to radiate a vibration of each string as a sound wave, wherein said main body further has a back plate oppositely disposed to said top plate, comprising: a vibration transmitter pressure-contacted to said top plate; a sensor for receiving a vibration force from the vibration transmitter and converting the vibration force into an electric signal; and a fixing means having a sensor arm with the sensor arranged thereon and an approximately parallel back arm, both arms extending from a squared-off bottom to form a “U” shape wherein spacing between said arms is freely adjustable to pressure-contact, via said sensor, said vibration transmitter at a pressure-contacting point to said exterior surface of said top plate and said back arm to an exterior surface of said back plate, in order to sandwich said main body between the arms and restrain the vibration at said pressure-contacting point, and said fixing means further comprises a top arm, having said sensor arm mounted thereon, wherein spacing between said top arm and back arm is freely adjustable, wherein the top arm and the back arm of the fixing means are pivotally attached together at a hinge point, and a spring member mounted at said hinge point forcibly and removably fixes said top arm to an exterior surface of said top plate and said back arm to an exterior surface of said back plate.
