A call control device for a mobile phone comprising an incoming call response means for sending to a mobile phone using a received voice path.

  According to a third aspect of the present invention, the mobile phone call control device according to the first or second aspect further comprises a ringing tone detecting means for detecting an incoming call to the connected mobile phone as a ringing tone. This is a mobile phone call control device.

  If the call control device of the present invention is connected to a mobile phone, it responds to the caller with a synthesized voice instead of the user, so that it is possible to talk without being noticed by surrounding people even in places where the call is restricted or self-discipline is required can do.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of a mobile phone call control device 1 according to an embodiment of the invention. The call control device 1 is used by being connected to a mobile phone 3.
Reference numeral 7 denotes a main body, and an earphone / microphone jack 9 of the main body 7 is inserted into and connected to an earphone / microphone connector 5 for hands-free calling of the mobile phone 3. The jack 9 is set to be compatible with a commercially available mobile phone.
Reference numeral 13 denotes an accessory. In the accessory 13, the earphone 15, the response switch 17, and the microphone 19 are integrally formed, and the connection terminal 21 is connected to the connector 11 of the main body 7.

Below, the structure of the main body 7 is demonstrated.
Reference numeral 23 denotes a CPU (control unit) which is the heart of the call control device 1 and controls all operations of the call control device 1.
The earphone / microphone jack 9 has a function as a reception unit that receives a received voice signal (analog signal) from the mobile phone 3 and a function as a transmission unit that transmits a transmission voice signal (analog signal). The received voice path (analog signal path) 25 and the transmitted voice path 27 (analog signal path) communicate between the connector 11 and the earphone / microphone jack 9. Amplifiers 26 and 28 are provided in the paths 25 and 27, respectively.
A normal hands-free call means is constituted by the accessory 13 including the earphone 15 and the microphone 19 and the above-described configuration of the main body 7.

  Reference numeral 29 denotes a voice synthesis IC (with built-in mask ROM), which synthesizes voice in response to a voice synthesis command from the CPU 23, and sends it to the received voice path 25 and the transmission voice circuit 27 via the amplifier 30. Predetermined voice message data is stored in the mask ROM of the voice synthesizer IC 29. When a voice synthesis command is received, a voice (voice signal) for voice announcement to a caller or user is created according to a predetermined voice synthesis program. . The voice synthesis IC 29 and the transmission voice circuit 27 are connected to constitute voice response means.

Reference numeral 31 denotes a changeover (analog) switch, and this changeover switch 31 is provided between the transmission voice path 27 and the connector 11. The change-over switch 31 operates in response to the audio mute control signal from the CPU 23 to connect the connector 11 and the transmission audio path 27, that is, from the state in which the caller can hear the user's utterance, That is, the user's utterance is switched to a state where the caller cannot hear, or conversely, the latter state is switched to the former state.
In the cut-off (voice mute) state, instead of the user's utterance, the voice synthesizing IC 29 utters according to the command of the CPU 23, and the voice and the user can hear the voice.
With the above configuration, response mode switching means is configured.

Reference numeral 33 denotes a detection unit for a pressing operation of the response switch 17. When the detection unit 33 detects the operation, it is reported to the CPU 23.
Reference numeral 35 denotes a ringing tone detection circuit. The ringing tone detection circuit 35 detects (extracts) a ringing tone (ringing tone) transmitted as a received voice signal when the mobile phone 3 receives an incoming call, and reports it to the CPU 23. That is, when there is an incoming call to the mobile phone 3, the CPU 23 reports from the ringing tone detection means that the mobile phone 3 is receiving an incoming call. With the above configuration, ringing tone detection means is configured.

Reference numeral 37 denotes a pseudo response switch. When selecting an incoming response, the CPU 23 sends an incoming response signal (one pulse output) from the pseudo response switch 37 to the mobile phone 3. With the above configuration, incoming call response means is configured.
Similarly, the pseudo response switch 37 sends an end signal to the mobile phone 3.
In the call control device 1, by providing the pseudo response switch 37, it is possible to share the received voice path 25, that is, to transmit the earphone output and the signal to the mobile phone 3.

  The mobile phone 3 has a built-in hands-free call setting means for judging the connection state of the earphone / microphone jack 9 and turning on the hands-free call when the jack 9 is connected. When the mobile phone 3 is connected to the mobile phone 3, the mobile phone 3 has a specification for automatically setting the hands-free call ON state.

Below, the operation | movement sequence of the telephone call control apparatus 1 is demonstrated according to drawing.
First, the call control device 1 is connected to the mobile phone 3 (power ON) and installed in a usable state.
As shown in FIG. 2, when there is an incoming call to the mobile phone 1, a ring tone is output from the earphone 15 (step S1). The ring tone is detected by the ringing tone detection circuit 35 and reported to the CPU 23.
If the incoming call is not answered, the user does not operate the response switch 17 and leaves it alone (step S2).

When responding to an incoming call, the user presses the response switch 17 to select one of the call modes (step S3).
The call mode is shaken as follows according to the type of pressing operation of the response switch 17 by the user.

(In normal call mode) (Figure 3)
When the response switch 17 is single-clicked during ringing tone detection, that is, during an incoming call (step S1), the CPU 23 starts communication processing for the first time, determines that the user has selected a response in the normal call mode, and receives an incoming call. A response signal is sent to the mobile phone 3 using the received voice path 25 (step S2). When receiving the signal, the mobile phone 3 establishes a call line and is in a call (step S3).
During the call, the microphone 19 (connector 11) and the transmission voice path 27 are connected, and the user speaks to directly talk to the caller.
When the response switch 17 is clicked four times, the CPU 23 determines that the call has ended (step S4), and sends a call end signal to the mobile phone 3 using the reception voice path 25 to cut off the call line ( Step S5), the operation sequence is finished.

(Answering call mode) (Fig. 4)
When the response switch 17 is double-clicked during ringing tone detection, that is, during incoming (step S1), the CPU 23 starts communication processing for the first time and determines that the user has selected a response in the answering call mode. An audio mute control signal is sent to the changeover switch 31 to cut off the microphone 19 (connector 11) and the transmitted voice path 27 (microphone mute) (step S2). Also, an incoming response signal is sent to the mobile phone 3 using the received voice path 25 (step S3). When receiving the signal, the mobile phone 3 establishes a call line and is in a call (step S4).

During a call, the microphone 19 (connector 11) and the transmission voice path 27 are cut off, and instead, the voice response means including the voice synthesis IC 29 and the transmission voice path 27 are connected and created by the voice synthesis IC 29. Talk to the caller with a new voice, that is, synthesized voice. Since this synthesized voice is output through the earphone transmission path 27, the user can hear the contents.
First, a voice message for starting answering (for example, “Yes, XX. I ca n’t talk right now. I ’m listening so please talk as it is.”) Is transmitted to the caller and user (step S5).

Then, the proxy conversation on the way is performed as follows according to the message content of the caller (step S7).
That is, when the response switch 17 is clicked, the CPU 23 determines that the response signal is a response signal, and synthesizes a predetermined voice message by the voice synthesis IC 29 according to the number of clicks. This voice message is also transmitted to the caller and user in the same manner as the answering start voice message.
In this embodiment, the voice message is “Yes” for one (single) click, “No” for two (double) click, “No” for three clicks, and later I'll call you. "

If the caller asks for a “yes” or “no” answer, tell the caller such a voice message so that the user can respond in real time without speaking, and then call again. There is no hassle to do.
In this way, the user can talk without being noticed by surrounding people by pressing the response switch 17. That is, a secret story is possible.

  When the response switch 17 is pressed for a long time (about 2 seconds) during a call, that is, when a call mode switching signal is received (step S8), the CPU 23 cancels the voice mute and a voice message to that effect (eg, “ "Switch to call.") Is transmitted to both the caller and the user (step S9), and the mode shifts to the normal call mode of FIG.

  If the response switch 17 is clicked four times during a call, the CPU 23 determines that the call has ended (step S6), and sends an end signal to the mobile phone 3 as in the normal call mode (step S10). The telephone line is interrupted and the microphone mute is canceled (step S11), and the operation sequence is terminated.

In the call control device 1, in the answering call mode, the user can hear the synthesized voice, and easily recognize even if there is an operation mistake of the response switch 17.
During a non-call, the CPU 23 is stopped and the current consumption can be reduced to about several tens of μA.

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to the above-described embodiment, and even if there is a design change within a range not departing from the gist of the present invention. Included in the invention.
For example, in the embodiment described above, the call control device is connected only to the earphone microphone connector 5 of the mobile phone in order to have a compact configuration, but it may also be connected to the control connector of the mobile phone. In that case, since it is possible to send and receive data to and from the mobile phone, the caller's data with the phone number as a key is captured, and when there is an incoming call, the name of the caller is announced by voice. You can also

  By using the mobile phone call control device of the present invention, it is possible to make a call without being noticed by surrounding people even in places where the mobile phone call is restricted or required to be self-restricted, and it is necessary to make a call again later. Disappears.
