DESCRIPTION OF THE PREFERRED EMBODIMENTS (Embodiment 1) FIG. 1 is a system schematic diagram of an embodiment of a portable telephone incoming call notifying device of the present invention.
FIG. 2 is a block diagram of the mobile phone call notifying apparatus according to the first embodiment, and FIG. 3 is a call connection sequence flow chart between the base station of the mobile phone and the mobile phone. In FIG. 1, one end of a connection cable 3 is connected to an output terminal 2 of a portable audio device 1, and the other end is connected to an input terminal 5 of a mobile phone call notifying device 4. The connection code 8 of the headphone 7 is connected to the output terminal 6 of the mobile phone call notifying device 4. The mobile phone call notifying device 4 is provided with a plurality of operation buttons 9 for operating the operation of the portable audio device 1 and the functions of the mobile phone call notifying device 4.

In such a configuration, when the portable audio device 1 performs a reproducing operation by using the operation button 9 and receives an incoming call to the portable telephone (or PHS) 10 during listening, a signal generated at the time of the incoming call is transmitted to the portable telephone incoming notification device. The synthesized sound that is detected by the radio wave detecting unit 4 and notifies the incoming from the voice synthesizing unit that is the notification signal generating unit, for example, the reproduced sound of the portable audio device 1 that is currently being listened to, such as “The mobile phone has arrived.” The user listens to the music through the headphone 7 instead of, or in combination with, the mobile phone 1 even while listening to music.
It is possible to know that the call has arrived at 0.

Referring to FIG. 2, the details of the portable telephone incoming call notification device 4 will be described. The radio wave detecting unit 11 receives a radio wave transmitted from a nearby mobile phone from the antenna 11a, detects that a calling signal (ALERT) in a sequence flow diagram described later continues for a certain period of time, and outputs a detection signal. The detection output of the radio wave detection unit 11 is transmitted via the switch 12 to the mobile phone call notifying device 4 and the CP for controlling the portable audio device.
It is input to U13. The operation unit (1) 14 is a switch 12
Is turned on and off. The operation unit (2) 15 has one or a plurality of operation buttons, communicates with the portable audio device 1 connected to the remote control terminal 16 via the CPU 12 by digital signals, and performs operations such as reproduction, stop, volume adjustment, and the like. Control. The display unit 17 displays the operating state of the portable audio device, an incoming call, and the like under the control of the CPU 13. When instructed by the CPU 13, the voice synthesizer 18 generates a synthesized voice for notifying the user of an incoming call or the like. The switch 19 switches off the audio signal from the audio signal input terminal 20 to the headphone terminal 21 at the time of an incoming call in response to an instruction from the CPU 13, and switches the output of the audio synthesis unit 18 to the headphone terminal 21 instead.

The operation of the above configuration will be described with reference to the flow chart of the incoming call connection sequence between the base station and the portable telephone shown in FIG. In the figure, when a user of a wired telephone dials to talk to a mobile phone, the base station transmits a call signal to the mobile phone in sequence 31 via the telephone exchange. When the mobile phone receives this call signal, it automatically sends a signal for answering to the base station. Next, in sequence 32, the base station transmits a wireless channel designation signal to the mobile phone, and sets up a wireless channel. After setting up the wireless line,
In step 33, a call setting signal (SETUP) is sent from the base station to the mobile phone, and the mobile phone instructs internally to generate a ring tone (RGT).
Transmits a paging signal (ALERT) to the base station. When the mobile phone goes off-hook (pick up the handset or press the reception switch), the response signal (CON
N) is sent to the base station, a response acknowledgment signal (CONN ACK) in sequence 36 is sent from the base station, and communication in sequence 37 starts.

In this process, the calling signal (ALERT) of the sequence 34 issued by the portable telephone has a longer signal duration than the other signals except for the call, and the call time is longer than the calling signal. Focusing on this, the radio wave detecting unit 11 of the mobile phone incoming call notifying device has the transmission frequency of 8 for the mobile phone.
00MHz, 1.5GHz, and PHS 1.
In any or all of the 9 GHz bands, a band filter capable of broadly receiving the entire band is provided, and the reception signal time is measured by a counter or a timer. If this time is set to the length of the ringing signal (ALERT), other signals with the base station will not be detected because they are shorter than this, and the signal for the call will be detected because it is much longer than this. It is not possible to make a call signal (A
(LERT) is detected, and only the call from the base station is detected, and the CPU
13 to output a detection signal. The CPU 13 receives this and switches the switch 19 from the audio signal input terminal 20 to the audio synthesizing section 1.
8 and then instructs the speech synthesizer 18 to output a synthesized speech. The voice synthesizing section outputs a synthesized voice set in advance, for example, “the mobile phone has arrived” and sends it out to the headphone 7 via the headphone terminal 21 to make the headphone 7 utter a voice and notify the user. At this time, an incoming call display can be performed on the display unit 17.

When the user confirms the call and presses the reset switch of the operation unit (2) 15, the CPU 13 stops the output of the synthesized voice unit 18, switches the switch 19 to the voice signal input terminal 20 side, and The output from the audio device 1 can be heard by the headphones 7. Instead of pressing the reset switch, the CPU 13 may automatically reset after a lapse of a predetermined time.

When the operation unit (1) 14 is operated, the switch 1
2 is turned off, and no incoming call is detected. For example, if there is another mobile phone nearby in a train, etc., if there is a frequent incoming call to an unrelated mobile phone, a notification of incoming call will be issued every time and listening will be interrupted. is there. It is also used to turn off the mobile phone when it is not in use to prevent it from malfunctioning with another person's mobile phone.

The operation unit (2) 15 performs operations such as reproduction, stop, and volume control of the portable audio device 1 in addition to resetting, converts the digital signal into a digital signal by the CPU 13, and sends the digital signal to the portable audio device 1 side. It is to make it. This operation can be performed by an analog signal.

In this example, the signal given to the headphone 7 by the switch 21 is switched to either the audio signal from the audio signal input terminal or the output from the audio synthesizing section 18. However, instead of the switch 19, a mixing circuit is used. May be provided, and the audio signal may be mixed with the synthesized signal of the voice synthesis unit 18. In that case, it is preferable that the mixing circuit reduce the audio signal at the time of mixing in order to clarify the notification.

Although the synthesized voice is generated by the voice synthesizing unit as the notification signal generating unit, a simple beep sound may be used instead of the synthesized voice for cost reduction.

In the above description, the audio signal sound was played while being cut off.
Is a portable audio device 1 with a remote control function.
Can be paused, and in this case, after the notification of the incoming call ends, the audio signal can be continuously listened to, so that the reproduced audio content is not missed.

In the present embodiment, the above configuration and operation enable the user to listen to the notification signal through the headphone when the portable audio device is received by the headphone while reproducing the sound with the headphone. When you cannot hear the ring tone or the vibration function does not work,
Further, even when the mobile phone does not have a vibration function, it is possible to reliably recognize the call.

Alternatively, the recording format of the recording medium of the portable audio device is digital recording. It may be sent as it is. Further, similarly to the first embodiment, the operation of the operation unit 2 is sent to the portable audio device 1 by a digital signal, and is processed by the CPU (2) 25 here. In the case of the first embodiment, since the audio signal was an analog signal, two signal lines each for two audio signals and one remote control signal were required, but a total of five signal lines were required. Also, signal transmission during this time can be easily performed wirelessly instead of wired.

The operation is different from that of the first embodiment in that the audio signal is transmitted digitally to the portable telephone incoming call notifying device 4, and this is transmitted to the CPU (1) 2
If the signal is converted into an analog signal in step 2, the subsequent operation is the same.
However, when the switch 19 is switched from the audio signal side to the connection point of the resistors R1 and R2 when an incoming call is detected, the audio signal and the synthesized voice are mixed, and the resistors R1 and R2 are mixed.
By appropriately selecting the ratio, the audio signal can be attenuated and the output of the voice synthesizer 18 can be easily heard.

As described above, in the present embodiment, the number of connection lines between the portable audio equipment and the portable telephone incoming call notifying device is greatly reduced by the above-described configuration and operation, and it is easy to perform wireless transmission.
