Phillips 1930 Loudspeakers



The ondes Martenot "Martenot waves", also known as the ondium Martenot, Martenot and ondes musicales, is an early keyboard-played electronic musical instrument invented in 1928 by Maurice Martenot and available in the 1930's. The original design was similar in sound to the theremin. The sonic capabilities of the instrument were later expanded by the addition of timbral controls and switchable loudspeakers--   (L-R) A small gong is used as the loudspeaker diaphragm to produce a 'halo' effect rich in harmonics, an iconically lyre-shaped loudspeaker, using strings to produce sympathetic resonances and a traditional, large loudspeaker
