电话自诞生以来,就一直以其旺盛的生命力持续不断地、迅速地向前发展,似乎从未有过衰败时期。从早期的直通式磁石电话,到后来的拨号式和按键式电话,其外观和功能已先后经历过几代的变化。 80年代后,当含有大规模集成电路的计算机芯片逐步应用到电话机上时,又使其功能进一步发生了根本性的变革。如自动录音、号码存储、可视、转接、重拨、免提、计时……,据说有些数字电话的功能甚至多达上百种。 Since the birth of the telephone, it has been continuously and rapidly moving forward with its strong vitality. It seems that the telephone never appears to have been decadent. From early straight-through magnet phones to later dial-up and push-button phones, the look and feel of several generations has changed. After the 1980s, when the computer chips containing large-scale integrated circuits were gradually applied to the telephone sets, their functions were further radically changed. Such as automatic recording, number storage, visualization, transfer, redial, hands-free, timekeeping ... ... It is said that some digital telephones even up to hundreds of functions.
