電話機原理

電(dian)(dian)(dian)話通(tong)(tong)信(xin)是通(tong)(tong)過聲能(neng)與電(dian)(dian)(dian)能(neng)相互轉換、并利用“電(dian)(dian)(dian)”這個媒介來(lai)傳(chuan)輸(shu)語言的一種通(tong)(tong)信(xin)技術(shu)。打電(dian)(dian)(dian)話時(shi)聲波作用于送話器上產生電(dian)(dian)(dian)流(liu)，電(dian)(dian)(dian)流(liu)沿著線路(lu)傳(chuan)達到(dao)對方電(dian)(dian)(dian)話機，再將電(dian)(dian)(dian)流(liu)轉化為(wei)聲波就完成(cheng)了遠程通(tong)(tong)話。

電話機怎么安裝

如何選購電話機

首先要選用與當地交換機制式相適應的電話機，然后要考慮電話機的功能，比如免提揚聲、液晶顯示、錄音應答等功能；購買前還要檢查電話機的外觀質量是否合格，聲音是否清晰無噪聲，聲調是否正常等。建議選擇正規品牌電話機，質量有保障。
