List of Hammond organs : ウィキペディア英語版 | List of Hammond organs The Hammond organ is an electric organ invented by Laurens Hammond and John M Hanert and first manufactured in 1935. Various models were produced, which originally used tonewheels to generate sound via additive synthesis, where component waveform ratios are mixed by sliding drawbars. Around 2 million Hammond organs have been manufactured, and it has been described as one of the most successful organs ever. The organ is commonly used with, and associated with, the Leslie Speaker. ==Tonewheel organs== Tonewheel organs generate sound by mechanical tonewheels that rotate in front of electromagnetic pickups. Each tonewheel assembly creates audio with low harmonic content, close to a sine wave. Inside the coil is a permanent magnet. As the teeth of the tonewheel pass by, the strength of the magnetism changes—when the tip of a tooth is closest to the tip of the magnet, the magnetism is strongest. As the magnetism varies, that creates AC in the coil, which becomes one of the frequencies used in harmonic synthesis.
