signal is output from the telephone communication unit, the transmission control unit gives
priority to the voice output signal output from the radio wave receiving unit. It can be
transmitted to the audio signal input / output unit, and the earphone unit can preferentially listen
to the audio from the telephone communication unit.
Therefore, when the user of the portable voice information handling apparatus listens to the
voice information of the broadcast radio wave received by the radio wave reception unit, the user
of the portable voice information handling apparatus does not need to particularly perform the
switching operation when a call is received from the other party. The voice information of the
other party of the call can be heard, and the handling can be further simplified.
[0009]
Further, by providing the configuration according to the fifth aspect, the transmission control
unit preferentially transmits the voice output signal from the telephone communication unit to
the voice signal input / output unit, the voice output signal of the radio wave receiving unit is a
voice signal When the telephone call unit receives a transmission signal from the other party of
the call when in a state of listening to the broadcast radio wave transmitted to the input / output

unit, a call for transmitting the voice output signal of the telephone call unit to the voice signal
input / output unit It switches by the switching means so that it will be in a state. As a method of
preferentially transmitting the audio output signal from the telephone communication unit to the
audio signal input / output unit, for example, a method of lowering the signal level of the audio
output signal of the radio wave receiving unit may be considered. By switching from the listening
state to the call state, it becomes possible to accurately hear the voice information from the
telephone call unit, and since simple switching operation is performed, simplification of the
device configuration can be achieved.
[0010]
Further, by providing the configuration according to the sixth aspect, the signal levels of the
audio output signal of the radio wave receiver and the audio output signal of the telephone call
unit are adjusted by the level adjustment means and transmitted to the audio signal input /
output unit. Ru. That is, it is necessary to adjust the signal level of the voice output signal of the
radio wave receiver and the voice output signal of the telephone call unit generally by including
an amplifier etc. The level adjustment means adjusts the level of the voice output signal of both
the telephone call unit and the radio wave reception unit by using the switching means to switch
to the voice output signal of the call unit and transmitting it to the voice signal input / output
unit. It is possible to further simplify the configuration.
[0011]

converted to sound and effectively emitted to the ear canal 53.
[0016]
Next, the operation of the portable voice information handling apparatus MV configured as
described above will be schematically described in relation to the operation by the user. In any of
the telephone mode and the radio mode described below, the microphone earphone ME is used
by attaching to the ear. When the portable voice information handling apparatus MV is used as a
portable telephone apparatus, the power switch 10 is turned on, and the mode switch 11 is set to
the telephone mode. By this setting, the controller CO sets the changeover switch 8 to a call state
in which the voice output signal of the telephone call unit 2 is transmitted to the jack 6. In this
state, when the user makes a call, after inputting the telephone number of the other party of the
call with the number setting button 2c, the user presses the call button 12 to operate the
telephone by the control command from the controller CO. A dial signal is transmitted from the
unit 2. When the other party picks up the telephone, the conversation becomes possible via the
microphone earphone ME, and when the user ends the conversation with the other party and the

user presses the disconnect button 13, the connection with the telephone line is disconnected. At
the time of this call, the volume of the other party's voice can be adjusted with the volume
adjustment button 9b. In addition, when a call is received from the other party when the
telephone mode is set, a conversation with the other party can be performed by pressing the call
button 12.
[0017]
On the other hand, when the portable voice information handling apparatus MV is used as a
radio receiver, the power switch 10 is turned on, and the mode switch 11 is set to the radio
mode. By this setting, the controller CO sets the changeover switch 8 to a broadcast radio wave
listening state in which the audio output signal of the radio wave receiver 1 is transmitted to the
jack 6. In this state, when the user selects a desired broadcast station using the channel selection
switching button 1c, the user can listen to a radio broadcast via the earphone unit 4 of the
microphone earphone ME. Also in this case, the volume of the radio broadcast sound can be
adjusted by the volume adjustment button 9b.
[0018]
In this radio mode, when a call is received from the other party, the telephone call unit 2 sends a
signal to the controller CO to notify that it has arrived. In response to this signal, the controller
CO switches the switch 8 from the radio wave listening state to the call state, and transmits the
voice output signal of the telephone call unit 2 to the jack 6. That is, the radio mode is
temporarily switched to the telephone mode. Along with this, the user who has been listening to
the radio broadcast until then knows that the call has been received from the information (for
example, the ringing tone) indicating the incoming call that can be heard from the earphone unit
4 and presses the call button 12 By operating, you can talk with the other party. When the call is
ended and the user presses the disconnect button 13, the controller CO switches the switch 8
from the call state to the radio wave listening state, and returns the state where the earphone
unit 4 can hear the radio broadcast. .
[0019]
That is, the switching means MC configured of the controller CO and the changeover switch 8
switches between the above-mentioned broadcast radio wave listening state and the call state,
and when in the radio wave listening state, the telephone communication unit 2 transmits the
other party. When receiving a signal, the broadcast radio wave listening state is switched to a call

state, and when an audio output signal is output from the telephone call unit 2, the voice output
signal is output from the radio wave receiver 1 The output signal is preferentially transmitted to
the audio signal input / output unit, that is, the jack 6.
[0020]
[Other Embodiments] Hereinafter, other embodiments will be listed.
In the above embodiment, the changeover switch 8 is used to switch between a broadcast radio
wave listening state in which the voice output signal of the radio wave receiver 1 is transmitted
to the jack 6 and a call state in which the voice output signal of the telephone call unit 2 is
transmitted to the jack 6. Although the switching is performed, the voice output signal of the
radio wave receiver 1 and the voice output signal of the telephone call unit 2 may be added and
transmitted to the jack 6. In this case, by separately adjusting the volume of the voice output
signal of the radio wave receiver 1 and the voice output signal of the telephone communication
unit 2, it is possible to distinguish and listen to both as needed. Also, in this case, the signal level
of the voice output signal of the radio wave receiver 1 and the voice output signal of the
telephone call unit 2 can be adjusted by the control of the controller CO, and a call is received
when listening to radio broadcast. In this case, the volume of the voice output signal of the radio
wave receiver 1 is automatically lowered, and the voice output signal of the telephone call unit 2
is automatically raised. The audio output signal of the receiver 1 may be preferentially
transmitted to the jack 6.
