In addition, the portable recorder 113 has a tuner unit 115 that demodulates and converts one or both audio signals of a radio broadcast signal or a television broadcast into an audio signal, in addition to the media conversion unit 114, The audio signal output from the tuner 115 can be adjusted by the volume controller 120 and output from the headphones 125.

Next, the operation of the information terminal system will be described.

First, the mobile phone 101 will be described.

First, the transmission operation of the mobile phone 101 will be described. After a call is set, the voice input from the microphone 109 is modulated by the modulation section 104, frequency-converted to a radio frequency by the radio section 103, and transmitted from the antenna 102. Is done.

On the other hand, in the case of reception, the radio signal received from the antenna 102 is converted to an intermediate frequency or a baseband frequency by the radio section 103 and the demodulation section 105 demodulates the radio signal while the mobile phone 101 is in a call waiting state. Along with
The control unit 106 determines whether or not the received signal is for the own station. If the received signal is addressed to the own station, the demodulated audio signal is output from the speaker 110.

Here, the control unit 106 performs an incoming call process, particularly when the received signal is for the own station, and sends an incoming call notification control signal to the incoming call notification sound generating unit 108 and the terminal 112. The incoming call notification sound generation unit 108 generates a sound for notifying the incoming call, for example, a pulse wave, in response to the input of the incoming call notification control signal, and outputs a speaker 110 or a terminal 111.
Is output to at least one of Normally, speaker 1
An incoming call notification sound from 10, for example, a beep, beep, beep, etc. sounds. By listening to the incoming call notification sound, it is determined that there is an incoming call to the mobile phone 101. When both the mobile phone 101 and the portable recorder 113 are used, the pulse wave is output from the terminal 111,
Input to the headphones 125 via the combiner 123,
For example, a sound such as a beep, a beep, or a beep is output from the headphones 125.

On the other hand, in the portable recorder 113, when the user performs a tape play operation on a playback operation unit (not shown), the control unit 117 instructs the media conversion unit 114 to perform playback. Data recorded in analog and / or digital format, for example, audio data such as music and conversation, is converted into an audio signal from a cassette tape or the like set in the cassette tape and reproduced. Here, the volume of the reproduced audio signal is manually adjusted by the volume controller 120 so that the user can listen to the sound with the headphones 125 well. The audio signal that has passed through the volume control unit 120 is output from the audio signal output terminal 121,
Is output as audio.

When the user performs a broadcast reception operation on a playback operation unit (not shown), the control unit 117 instructs the tuner unit 115 to receive a broadcast.
Demodulates a designated radio broadcast or television broadcast audio signal, converts the demodulated audio signal into an audio signal, and outputs the audio signal to the volume control unit 120. The received broadcast audio is output from the headphones 125 at the volume adjusted by the volume control unit 120. Will be done.

Next, an incoming call notification operation in the information terminal system will be described.

In the mobile phone 101, the antenna 10
The control unit 106 demodulates the radio signal received at step 2 and if it is destined for the own station, the control unit 106
And a terminal 112 to transmit an incoming call notification control signal. The incoming call notification sound generation unit 108 generates an incoming call notification sound based on the input incoming call notification control signal and outputs it to the speaker 11.
Output from 0. Alternatively, the notification sound is output from the terminal 111, and the incoming notification sound is output as sound from the headphones 125 via the combiner 123.

Here, when the user operates the portable recorder 1
When the mobile phone 13 is not operated or when there is no sound, for example, the incoming call notification sound from the headphones 125 indicates that there is an incoming call to the mobile phone 101.

On the other hand, when the user operates the portable recorder 11
In the case where the audio of the cassette tape or the broadcast is being reproduced in step 3, the incoming call notification sound such as pi, pi, pi is masked by the reproduced sound.
It may not be known that 1 has received an incoming call.

Therefore, in the case of this information terminal system, an incoming call notification control signal output to the speaker 110 is transmitted to the terminal 11.
2 to the control unit 117 of the portable recorder 113 via the connection cable 124 and the terminal 121.

When the portable recorder 113 receives the incoming call notification control signal sent from the control unit 106 of the mobile phone 101, the control unit 117 determines the volume of the audio signal being reproduced from the volume control unit 120 based on the incoming call notification sound. The sound volume control unit 120 is controlled so that the sound quality is also reduced, or the sound quality is changed to a sound quality different from the incoming call notification sound, or both.

Here, the volume control operation performed in this system and its variations will be described with reference to FIG.

As shown in FIG. 2A, the volume control operation at which the user can best recognize the incoming call is as follows, at the time ts when the incoming call notification control signal is received from the control unit 106 of the mobile phone 101, Control that immediately reduces the volume level Vh of the voice to the volume level Vl that is lower than the incoming notification sound is conceivable. However, the example of FIG. 2A has the advantage that the incoming notification sound can be confirmed almost simultaneously with the reception of the incoming signal, but the sound being played back by the portable recorder 113 fluctuates rapidly, so that the user may feel uncomfortable. There is a fear of embracing. Further, there is a possibility that the user may mistake the portable recorder 113 for a malfunction of the sound output system. Therefore, in order to prevent such a feeling of discomfort and discomfort, as shown in FIG. 2B, at the time ts when the incoming call notification control signal is received, the volume level Vh of the sound being reproduced is first set. When the incoming notification sound Vbell is heard by one step, the level is lowered by one step again, and at a time te several seconds later, the volume level Vl becomes lower than the incoming notification sound Vbell.
A control may be performed to lower the volume level Vh of the sound being reproduced. As a result, the sense of discomfort when the sound being reproduced changes can be reduced. In the example shown in FIG. 2B, the control of the level change from the volume level Vh to Vl is performed in three steps, but the control may be performed with fewer or more steps than the three steps.

Further, as shown in FIG. 2 (c), the volume level Vh of the voice being reproduced is gradually lowered from the time point ts when the incoming call notification control signal is received, and the volume finally becomes lower than the incoming call notification sound. Control for lowering to level Vl may be performed. As a result, it is possible to reduce the sense of discomfort when the voice changes, as compared with the case where the sound is changed stepwise.

Further, as shown in FIG. 2D, at the time point ts when the incoming call notification control signal is received, the volume level Vh of the sound being reproduced is gradually lowered, and the incoming call notification output from the mobile phone 101 side. By gradually raising the sound Vbell,
The user may be able to recognize the change in the state. The volume may be set to the 0 level (silence) for the volume level Vl.

When the call by the mobile phone 101 ends, the control unit 106 of the mobile phone 101 sends a signal (call end notification signal) notifying the end of the call to the control unit 117 of the portable recorder 113.

Control unit 117 of portable recorder 113
When receiving the call end notification signal,
And the media conversion unit 114 or the tuner unit 1
15 increases the audio signal being reproduced to a level before being controlled by the incoming notification signal or to a volume at which comfortable listening is possible.

According to the information terminal system of the first embodiment, when the portable recorder 113 receives a call while the portable recorder 113 is reproducing music or conversation sound, as described above, the portable recorder By performing volume control, the incoming call notification sound generated in the mobile phone 101 is transmitted to the headphone 1 through the terminal 111 and the combiner 123.
The user can clearly recognize the incoming call using the headphones 125 by inputting the information to the address 25. The same effect can be obtained by controlling not only the volume but also the sound quality of the sound being reproduced.

The control information for restoring the volume is as follows:
The information may be stored in the storage unit 119 provided in the portable recorder 113, and the volume restoration control may be performed based on the information. That is, when the control unit 117 receives the incoming call notification signal, the volume control unit 120 controls the volume output from the portable recorder 113 so as to decrease the volume, and performs the suppression amount of the volume and the stepwise suppression control. In this case, information on the time until the predetermined amount of suppression is reached is stored in the storage unit 1.
When the control unit 117 receives the call end notification signal, the control unit 117 may restore the volume based on the information in the storage unit 119. If the media conversion unit 114 is an audio signal playback device, the following control may be performed.

Upon receiving the incoming call notification signal, the control unit 117 operates the volume control unit 120 to immediately stop the volume of the audio signal output from the portable recorder 113, and also stops the operation of the media conversion unit 114. The call ends,
When the control unit 117 receives the call end signal, it immediately operates the volume control unit 120, returns the volume to the level before the call, and then operates the media conversion unit 114, so that the information recorded on the media is overlooked. Disappears.

Alternatively, upon receiving the incoming notification control signal, the control unit 117 of the portable recorder 113 records the position of the information of the cassette tape being reproduced by the media conversion unit 114 at that time, and records it in the storage unit 119. . In this case, for example, a counter or the like interlocked with the cassette reel of the cassette tape is provided, and numerical information counted by this counter is recorded.

During the incoming call notification control, the media converter 114
Is operated, the control unit 117 of the portable recorder 113 controls the volume control unit 120 so that the audio signal output from the portable recorder 113 is reduced immediately or stepwise until the volume of the incoming call notification sound can be confirmed. I do. When the call by the mobile phone 101 ends, the control unit 106 of the mobile phone 101
3 sends a signal notifying the end of the call. When receiving the call end notification signal, control unit 117 stores in storage unit 1.
Based on the information recorded in the portable recorder 11, the portable recorder 11
The third control unit 117 performs control so that the audio information reproduced by the media conversion unit 114 can be reproduced in a state when the incoming call notification signal is received. Further, information before the time when the incoming call notification signal is received may be reproduced.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 shows the configuration of the information terminal system according to the second embodiment of the present invention. In the first embodiment, the mobile phone 101 and the portable recorder 113
