1、 中文摘要中文摘要 面包型电话机设计与制作 摘要 本套件为目前最新型的面包型电话机,它具有防雷、抗干扰、静音、暂停、重拨功 能和特大振铃声音、体积小巧、制作容易等优点。此电话机无需安装电池,直接将正在 使用的电话机的外线插头拔下来插在本电话机的插座内,提起话筒便可以拨打与接听电 话。.本电话机以集成电路 IC1(GF2410 型)为单独的电话音乐芯片,即来电响铃声 由它产生,另一个 IC2(9102D 型)是主电路板的集成块,主电路由它处理。.三极管 Q1、Q3 为普通的 9014,值大于 300 倍即可,也可以用它的高频小功率三极管如 9011、 9013、 9018、 3DG6、 3DG2
2、01 等代用。 .二极管分为开关二极管 1N4148 和稳压二极管 (4.7V 和 27V) 。.电阻、电容可在一定范围内选用。.电声器件如喇叭、蜂鸣片、驻极体可 选其它型号代替,但只要允许好安装即可。.各元件在安装的时候,应尽量装低一点, 电解电容采用卧室安装,以防盖子不好盖上,经过检查无误便可安装。.主板和按键 板通过 11 芯排线连接并接上喇叭和驻极体后安装在话筒内,铃音板接上直线插座和蜂 鸣片后安装在底座上,底座和话筒通过可伸缩线连接起来,电话线插在直线插座上后即 可进入到接、打电话的调试。 关键词:Protel Multisim 拨号电路 通话电路 振铃电路 面包型电话机 Engli
3、sh Abstract Design and manufacture of bread-based phone Abstract:The kit is the latest type of bread-type phones, it has a lightning protection, anti-jamming, mute, pause, redial function and big ringing sound, small size, making easier and so on. This phone without having to install the battery dir
4、ectly to the phone being used outside of the plug inserted in the pulling down telephone outlet, the microphone will be able to initiate and receive calls. . The telephone with integrated circuit IC1 (GF2410 type) as a separate phone music chips, caller ring tone that emanates from it, and the other IC2 (9102D type) is the main circuit board of the integrated block, the main circuit by its address. . Transistor Q1, Q3 as a normal 9014, can be greater than 300 times, you can also us
