苏格兰科学家亚历山大·格拉汉姆·贝尔因为发明电话而闻名于世。但是他并不是第一个通过电线传输声音的人。而且,他的电话也并不完美——他是在其他科学家的帮助下才得以改进。许多发明家还宣称于贝尔之前就已经发明了电话,而且有些人险些获得这个不可思议的装置的专利。 Scottish scientist Alexander Graham Bell is famous for calling. But he is not the first person to transmit sound over wires. And his phone was not perfect - he was improved with the help of other scientists. Many inventors also claim that they had already invented the phone before Bell, and that some people almost won the patent for this incredible device.
