Description

The automatic process of chopping of speaker phone talk

The present invention relates to a kind of method of automatic cut-out telephone set speaker phone talk part, specifically, relate to a kind of method of dialing intact number or having communicated automatic cut-out speaker phone talk machine when detecting busy tone afterwards.

Present patent application proposes according to korean patent application 50719/1995, also this patent application is included for your guidance here.

In general loudspeaking telephone set, when will conversing, the user to push the speaker phone talk key earlier or key on hook dial redials, must push speaker phone talk key or key on hook dial behind the talk-through again to cut off talk line.

Inconvenient part is with regard to here: the user must push speaker phone talk key or key on hook dial once more to cut off talk line at trunks busy or after having communicated.

Also have such problem in addition: as long as the user does not push speaker phone talk key or key on hook dial after talk-through, telephone system is just constantly counted the power taking telephone expenses.

Therefore, the purpose of this invention is to provide the method for cutting off talk line when detecting busy tone in a kind of telephone set speaker phone talk process automatically.

For reaching above-mentioned purpose of the present invention, the automatic process of chopping of telephone set speaker phone talk provided by the invention is connected talking path when comprising the following steps: that speaker phone talk key or key on hook dial are in input state makes telephone set enter the speaker phone talk state, and cuts off the speaker phone talk loop when detecting busy tone under the speaker phone talk state.

Fig. 1 is the block diagram of speaker phone talk telephone set of the present invention.

Fig. 2 is the control flow chart that the present invention cuts off talk line when detecting busy tone in the speaker phone talk process automatically.

Describe content of the present invention in detail referring to accompanying drawing below.

As shown in fig. 1, keyseat 10 produces dial key signal, key signals on hook dial or raises one's voice The talk key signal, and have the display element that resembles liquid crystal display or light emitting diode and so on. Control Element 12 processed is being controlled the whole course of work of telephone set, and also conduct is to detecting the response of busy tone Automatically cut off speaker phone talk. Ring detecting element 14 connects telephone line, and its effect is to detect From the bell signal of telephone line, provide it to control element 12. Sound equipment detecting element 16 Connect telephone line, its effect is the various acoustic signals that detect from telephone line, and with it Offer control element 12 after converting numerical data to. Conversation control element 18 is in control unit Switch on or off the talking path of telephone line under the control of part 12. Speaking circuit element 20 exists Under the control of control element 12 telephone line is connected on the speaker phone talk device 26. Speaker phone talk Device 26 is made up of loudspeaker 22 and microphone 24. Loudspeaker 22 passes through speaking circuit the user The voice signal that output was received via speaking circuit element 20 when element 20 was conversed with other people. Pass Sound device 24 when the user converses with other people by speaker phone talk device 26 to 20 of speaking circuit elements Go out voice signal.

As shown in Figure 2, when the method for cut-out talk line comprises the following steps: that speaker phone talk key or key on hook dial are in input state automatically when detecting busy-back signal in the speaker phone talk process, drive telephone set after the connection talking path and makes it enter the speaker phone talk state; Whether judgement detects busy-back signal under the speaker phone talk state; Cut off the speaker phone talk loop when detecting busy-back signal; Can not detect busy-back signal but speaker phone talk key or key on hook dial cut off the speaker phone talk loop when being in input state; Fulfil this enter key function corresponding when other key is in input state with can not detecting busy-back signal.

Describe most preferred embodiment of the present invention in detail referring to accompanying drawing below.

Which key whether as shown in Figure 2, control element 12 detects on the keyseat 10 in step 101 has be in input state.If there is any key to be in state, it is key on hook dial or speaker phone talk key that control element 12 just detects the key that is in input state in step 102.If the key that is in input state is neither key on hook dial neither the speaker phone talk key, control element 12 is just fulfiled function corresponding in step 103 by the key of being exported.On the contrary, if being in the key of input state in the step 102 is key on hook dial or speaker phone talk key, control element 12 just makes it connect talking path at step 104 control conversation control element 18, enters the speaker phone talk state but also control speaking circuit element 20 makes it drive telephone set.Telephone set is to drive like this to make it enter the speaker phone talk state, promptly can dial the number after key entry speaker phone talk key or the key on hook dial under idle condition, can continue conversation when perhaps keying in speaker phone talk key or key on hook dial under talking state.When no matter dialling or conversing, whether control element 12 detects busy-back signal at step 105 detection of sound detecting element 16.Here, busy-back signal callee after calling party dialing is in talking state or both sides has a side to produce during on-hook in communication process.If detect busy tone in step 105, control element 12 will make it cut off communication loop at step 106 control conversation control unit 18.Control element 12 makes it by cutting off speaker phone talk circuit cancellation speaker phone talk at step 107 control speaking circuit element 20.

If can not detect busy-back signal in step 105, whether control element 12 will detect on the keyseat 10 in step 108 has any key to be in input state.If any key is not in input state, program just turns back to step 105.If have any key to be in input state in step 108, it is key on hook dial or speaker phone talk key that control element 12 will detect the key that is in input state in step 109.If the key that is in input state is neither key on hook dial neither the speaker phone talk key, control element 12 is just fulfiled the key function corresponding that this is in input state in step 110.If what be in input state in the step 108 is key on hook dial or speaker phone talk key, control element 12 will make it cut off talking path at step 106 control conversation control element 18.Control element 12 control speaking circuit elements 20 make it by cutting off speaker phone talk circuit cancellation speaker phone talk.

In sum, because telephone set of the present invention passes through to cut off speaker phone talk loop cancellation speaker phone talk when dialing detects busy tone afterwards when conversation or under the speaker phone talk state, thereby the user need not to manually type in once more speaker phone talk key or key on hook dial.In addition, even the user does not push the speaker phone talk key or hangs dial key after having communicated, also can avoid telephone system that its accident of carrying out is chargeed.

Therefore, self-evident, the present invention is not limited to the illustrated embodiments of thinking disclosed herein, and more precisely, the present invention is not limited to the described specific embodiment of this specification, but the exception described in this specification appended claims.
