图 6是本发明电原理图。
实现本发明的最佳方式
如图 1所示， 本发明电话机由语音处理器 12、 动态存储器 （RAM) 、 程序存储器 ( ROM ) 、 键盘输入 16、 语音数码转换器 9、 功放器 5、 放大器 8、 话音网络 7、 铃声感 应器 1 1、 调制解调器介面电路 15、 电子开关 6、 拨号电路 10、 话筒 2、 喇叭 4和外接调 制解调器 14等组成； 另外， 3是话筒插头， 1是直线插头 1， 13是直线插头 2。
如附图 2所示， 本发明电话卡由语音处理器 12、 语音数码转换器 9、 功放器 5、 放 大器 8、 话音网络 7、 铃声感应器 11、 PC电脑介面 15、 电子开关 6、 拨号电路 10、 话筒 2、 编程及接于电脑的调制解调器 14等组成； 箭头连至 PC电脑。
结合附图 1、 4所示， 当有铃声送至直线 1、 铃声感应器 11会送出讯号给语音处理 器 12， 当铃声响声后， 语音处理器 12控制电子开关 6将直线 1接线， 当直线接线后， 语音后理器 12会通过语音数码转换器 9、 放大器 8、 话音网络 7及电子开关 6送出语音 讯号至直线 1通知来电者输入密码及要转接的电话号码。 当来电者输入双音频的密码 及电 ¾号码后， 此双音频讯号会通过话音网络、 放大器 8及语音数码转换器 9送至语 音处理器， 语音处理器会检查密码是否正确及电话号码是否有对应的互联网地址， 如两者都存在， 处理器会经 RS232介面控制调制解调器 14以直线 2打出由直线 1输入的 电话号码， 当对方电话线 （即同等转接器接上的直线 2 ) 接通及响铃声后会将直线 2 自动断线。 此时， 对方相同的转接器在收到 3声后停止铃声讯号， 会控制调制解调器 经直线 2拨号至互线网络， 直至连上互联网络， 再等候呼唤。 与此同时， 这方转接器 也同样经直线 2接上互联网络， 并将内存对应的网址经互联呼唤对 βΐ， 当对方的转接 器收到呼唤后， 处理器 12会送出响铃至功放器 5在喇叭 4放出或控制拨号电路 10经直 线 1拨号于其它电话系统， 等候对方接听， 如此便完成一个互联网通话的连接。
图 3、 图 4、 图 5原理与上述一样。 其中 17是转接器， 18是数字交换机， 19是互联 网， 20是转接卡， 21是 PC电脑， 22是手提无线电话。 现结合附图 6说明本发明工作原理。
图 6为转接器基本电路图， 其中 U2 (79L05)与 U3 (78L05)为电源稳压电路， U4 (27C512)与 U5 (TMS44410)为存储器电路， U6 (WS2206)为语音微处理器， U8与 U1 TP3054)为语音数字转换器， U10 (LM324)与 T1为话音网络与放大器， U9 (KA2213) 为喇叭功率放大电路， Q1与 RL1 (磁控开关） 组成电子开关电路， U12为铃声感应电 路， J1为直线电话一的插头， U13 (1488)、 U14 (1489)与 U15 (8251)为 RS232的介面电 路。
当 J1收到电话铃声， 此铃声讯号会经 C1传至 U12的发光二极管， U12会将二极管 的光讯号再转为电讯号送至 U6的第 62脚， U6收到此铃声讯号后会控制 37脚输出一个 低电位， 此一低电位会令 Q1导通而令 RL1的磁簧开关接至导通状态， 因此直线一被接 通。
当接通后， 来电者会送出双音频的密码及电话号码 （或语音） 至直线 L 当直线 1 ( J1 ) 收到双音频讯号后， 此讯号会经 T1耦合至放大器 U10A的第 3脚输入端， 经 U10A及 U10C放大后由 8脚输出再送至 U11的 16脚， U11将输入的音频讯号转为数码由 11 脚输出送至 U6的 19脚， U6将输入讯号分析及处理并转为一系列控制程序， 首先 U6透 过 DO至 D7数据汇流排及 PD0至 PD12等控制线控制 1315将并联数据 DO至 D7转为串联数据 经脚位 19输出， 而控制讯号经 23， 24脚位输出， 这些讯号再经 U13及 RS232接口送至 调制解调器。
而由调制解调器输出的讯号经 RS232接口及 U14送至 U15输入端 3， 17及 22脚， 其 中 3脚为串联数据， 17及 22脚为控制讯号， U15将 3脚的串联数据转为并联数据经 DO至 D7汇流排送至 U6， U6将接收的数据处理后转为输出的控制讯号或语音讯号。
当 U6接收的数据为响铃控制时， U6会于脚位 13输出数字讯号至 U11的 6脚， U11会 将输入的数码转为声频讯号在 3脚输出并送至 U9放大推动喇叭 LSI输出铃声。
当 U6接收的数据为拨号控制或语音时， U6会于脚位 31输出数字讯号至 U8的 6脚， U8会将输入的数码转为双音频或语音在 3脚输出并送至 U10D放大于 T1耦合至电话线。 工业应用性
①可作点对点长途电话通话： 由于互联网收费便宜， 客户通过此装置可增加话 音通讯， 对整体、 大型客户发展有很大帮助。
②可将目前工商业普遍采用的电话系统安上互联网作语音通话， 增加电话应用 性。 ③当用户浏览网页时， 如果想与对方直接通话， 用户只要按对方互联网电话号 码， 用户可以及时用连接转接卡的普通电话作互联网通话， 同一时间也可浏览网 页， 对工商业在互联网上下订单、 技术服务咨询、 购物及订票均有极大帮助。
④可在互联网设下电话查询， 语音广播； 但用户只需付互联网费用， 对一些国际贸 易的公司而言， 用户无须付出昂贵的长途电话费， 也可得到公司提供的服务。
