Abstract
Abstract A piezoelectric pickup bridge for capturing the vibrations of a stringed musical instrument and comprising two parts separated by a resilient pad, the upper part carrying an adjustable screw that transmits vibrations to a transducer. A tone and volume compensating circuit for a sound amplifier connected to said transducer and comprising resistances and capacitances for selectively boosting or attenuating high or low frequencies and simultaneously maintaining substantially constant the overall gain of the system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A bridge for a stringed musical instrument, said bridge comprising a bottom portion and a top portion, resilient means supporting said top portion upon said bottom portion for vibratory movement of The former in at least one of three perpendicular directions, said bottom portion including an electromechanical transducing cartridge having an input and an output, and means defining a pointed end on said top portion, said pointed end establishing a point contact with said cartridge input, said point contact transmitting to said cartridge input any vibratory movement provided by said top portion.
Claim 2
Dependent Claim
92 words
A bridge for a stringed musical instrument, said bridge comprising a bottom portion and a top portion, resilient means supporting said top portion upon said bottom portion for vibratory movement of The former in at least one of three perpendicular directions, said bottom portion including an electromechanical transducing cartridge having an input and an output, and means defining a pointed end on said top portion, said pointed end establishing a point contact with said cartridge input, said point contact transmitting to said cartridge input any vibratory movement provided by said top portion.
Claim 3
Dependent Claim
20 words
A bridge according to claim 1, wherein said means defining a pointed end is rigidly connected to said top portion.
Claim 4
Dependent Claim
123 words
A bridge for a stringed musical instrument, said bridge comprising a U-shaped bottom portion defining a free space, an electromechanical transducing cartridge housed within said free space, a resilient pad secured to said bottom portion, and a top portion of triangular cross section, the base of which rests upon said resilient pad for vibratory movement of the former in at least one of three perpendicular directions, said top portion including a vibration transmitting and adjusting screw having a pointed free end extending into said free space and establishing a point contact with said cartridge to transmit any vibratory movement thereto provided by said top portion and the vertex of said top portion having slots defined therealong for receiving the strings of the instrument.
Claim 5
Dependent Claim
123 words
A bridge for a stringed musical instrument, said bridge comprising a U-shaped bottom portion defining a free space, an electromechanical transducing cartridge housed within said free space, a resilient pad secured to said bottom portion, and a top portion of triangular cross section, the base of which rests upon said resilient pad for vibratory movement of the former in at least one of three perpendicular directions, said top portion including a vibration transmitting and adjusting screw having a pointed free end extending into said free space and establishing a point contact with said cartridge to transmit any vibratory movement thereto provided by said top portion and the vertex of said top portion having slots defined therealong for receiving the strings of the instrument.
Claim 6
Dependent Claim
112 words
A bridge for a stringed musical instrument, said bridge comprising a bottom portion and a top portion resilient means supporting said top portion upon said bottom portion for vibratory movement of the former, at least one blocking member arranged between said bottom portion and said top portion to dampen the vibrations in at least one of the three possible perpendicular directions of the vibratory movement, said bottom portion including an electromechanical transducing cartridge having an input and an output, and a projection rigidly connected to said top portion and defining a pointed end establishing a point contact with said cartridge input for transmitting thereto any vibratory movement provided by said top portion.
Claim 7
Dependent Claim
112 words
A bridge for a stringed musical instrument, said bridge comprising a bottom portion and a top portion resilient means supporting said top portion upon said bottom portion for vibratory movement of the former, at least one blocking member arranged between said bottom portion and said top portion to dampen the vibrations in at least one of the three possible perpendicular directions of the vibratory movement, said bottom portion including an electromechanical transducing cartridge having an input and an output, and a projection rigidly connected to said top portion and defining a pointed end establishing a point contact with said cartridge input for transmitting thereto any vibratory movement provided by said top portion.
