Abstract

312,689. Bethenod, J. May 31, 1928, [Convention date]. Electrically-vibrated instruments.-In an electrical musical instrument utilizing an oscillating circuit which consists of a source of alternating current 1 feeding an artificially loaded line 2 originally resonant to the normal series of frequencies 1, 3, 5, 7, &c., this series is varied to vary the timbre by closing the line by an impedance 5 of preselectable value. The loud speaker is connected at 7 to the secondary of a transformer 6, the circuit 7 also preferably containing an amplifier, and wave traps for filtering out frequencies not required.
