Embodiment

Referring to Fig. 1, Fig. 1 is disclosed a kind of structural representation of automatically opening on-hook telephone device in the utility model specific embodiment one.Comprise: microprocessor 11, Keysheet module 12, ring detection module 13, howler tone detection module 14, hands-free intercommunication module 15 and the preset number memory module 16 of raising one's voice.Wherein, Keysheet module 12, ring detection module 13, howler tone detection module 14, the hands-free intercommunication module 15 of raising one's voice are connected with microprocessor 11 respectively, and preset number memory module 16 can be stored preset number.When phone uses as calling party, user's SPKR key in module 12 that pushes button, microprocessor 11 detects the change in voltage of the pin being connected with key-press module 12, according to internal processes, arrange the hands-free start of phone, the numerical key that now user can press key-press module 12 dials, and phone is connected in the rear wait of having dialled; After end of conversation, can realize on-hook by the SPKR key of pressing on key-press module 12, also can anyly operate, wait for that microprocessor 11 detects howler tone counting by the howler tone shaping circuit of howler tone detection module 14, realizes automatic hand-up after howler tone reaches 10 times.

Referring to Fig. 2, Fig. 2 is the circuit theory diagrams of the utility model embodiment bis-.

The microprocessor of the present embodiment adopts HT95R23 chip, is respectively arranged with key circuit 21 as Keysheet module, holding circuit 22, the ringing circuit 23 as ring detection module, incoming call decoding circuit 24, as the howler tone testing circuit 25 of howler tone detection module, preset number memory circuit 26 as preset number memory module, reset circuit 27, on-hook power supply 28, as the hand-free circuit 29 of the hands-free intercommunication module of raising one's voice in the periphery of HT95R23 chip.

While using this telephone plant as calling party, user's SPKR key on circuit 21 that pushes button, microprocessor detects the change in voltage of the pin being connected with key circuit 21, according to internal processes, arrange the hands-free start of phone, the numerical key that now user can press key circuit 21 dials, and phone is connected in the rear wait of having dialled; Can be by the HOLD key pushing button on circuit 21 in communication process, microprocessor detects the change in voltage of the pin being connected with key circuit 21, according to internal processes, activation holding circuit 22 is set phone is entered to hands-free hold mode, current talking is held; The SPKR key again pushing button on circuit 21, can remove maintenance, recovers hand-free call; After end of conversation, can realize on-hook by the SPKR key of pressing on key circuit 21, also can anyly operate, wait for that microprocessor detects howler tone counting by the howler tone shaping circuit of howler tone testing circuit 25, realizes automatic hand-up after howler tone reaches 10 times.
