telharmonium

20世纪早期，就有了基于同样概念的电子合成器：电传簧风琴。

Electrical synthesiser based on identical concepts appeared in the early 1900s: the Telharmonium.

The Telharmonium worked by adding together the sounds from dozens of electro-mechanical tone generators to form complex tones.

它通过将电子机械声音发器产的声音相加以形成复杂的音色来演奏。
