Hunnings received a patent on September 16, 1878 for a new type of carbon microphone (then called transmitters) for use with telephones. The Hunnings transmitter provided multiple contacts between the diaphragm and a chamber containing loosely packed carbon granules. The Hunnings transmitter produced a stronger voice signal than the Bell electromagnetic transmitter and was therefore more practical for long distance communication. The Hunnings patents were purchased by the Bell Telephone company which improved and manufactured more than 10,000 transmitters of the Hunnings design after which it was replaced by the White "hard-back" transmitter.〔Coe, pages 36-37〕 == See also == Invention of the telephone 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Henry Hunnings」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
