Abstract
After the invention of the first microphone in 1876, carbon microphones have been introduced in 1878 as key components of early telephone systems. in 1942 ribbon microphones were developed for radio broadcasting. The invention of the self-biased condenser or electret microphones (ECM) in 1962 represented the first significant breakthrough in this field. Indeed, electret microphones, ensuring high-sensitivity and wide bandwidth at low cost, have dominated the market for high-volume applications until the last decades, when MEMS microphones started to gain popularity [1].Keywords
