电话是人们日常生活和工作中使用最广泛、最简便的一种电气通信工具。自从1876年问世以来,历经了人工、自动和电子三代。在当今电子技术和电子计算机广泛使用的新技术革命中,电话将日益发挥巨大的作用。吉他的启迪1832年,美国绘画家莫尔斯成功地发明了电报,开创了使电为人类服务的新纪元。这件事给英格兰人贝尔以极大启示。他想既然字符能用电流来传送,难道声音不能用电来传送吗?他决心将神话中的“顺风耳”变成现实。在实验过程中,贝尔和他的助手华特生不知经过了多少日日夜夜,电话发出的声音始终小得不能被人听清。一天傍晚,贝尔在街头漫步,一曲优美的吉他声传来。这琴声象流星在夜空中发出耀眼的闪光,触动了他的灵感。吉他的共鸣箱可以增强音响,能否将它移植到电话机上呢? Telephone is one of the most widely used and simplest electrical communication tools in daily life and work. Since its introduction in 1876, it has gone through three generations of artificially, automatically and electronically. In today’s revolutions in new technologies that are widely used by electronic and electronic computers, telephony will play an increasingly important role. Guitar Inspiration In 1832, the American painter Morse successfully invented the telegraph and opened up a new era in which electricity can serve humanity. This incident greatly inspired Bell of England. Since he thought that the characters could be transmitted by electric current, could the sound not be transmitted by electricity? He was determined to make the mythical “pleasure” a reality. During the experiment, Watson and his assistant Watson did not know how many days and nights passed and the voice of the phone was always too small to be heard. One evening, Bell walked the streets, a beautiful guitar sound came. The melodious meteor flashed in the night sky, touched his inspiration. The resonance box guitar can enhance the sound, can it be transplanted to the phone?
