FIG. 7 is a sequence diagram showing an operation when a loudspeaker call is made in a mode other than the transceiver mode. When the user performs a predetermined key operation on the operation unit 16 to set, for example, the public mode, the mode setting unit 40 sets the public mode according to the operation. As a result, the communication control unit 42 thereafter controls communication so as to perform communication via the station (line network). Specifically, as shown in FIG.
The communication control unit 42 transmits an outgoing signal to the station through the wireless unit 22 based on the outgoing call operation of the user. As a result, the station sends the incoming signal to the PHS terminal 54 of the other party,
When the terminal device 54 responds and sends an incoming response signal back to the station, the station sends an outgoing response signal to the PHS terminal device 2.
Thereafter, a call can be made between the PHS terminal devices 2 and 54.

In this embodiment, the loudspeaker control means 50 searches the storage area relating to the public mode in the storage means 44. In this case, too, it is assumed that the loudspeaker selection information is stored in the storage area. , The loudspeaker control means 50
The wireless unit 22 supplies the audio signal received from the partner PHS terminal device 54 to the amplifying unit 28.

Therefore, the audio signal received by the radio section 22 is amplified by the amplification section 28 of the loudspeaker 26 and supplied to the speaker 30 to make the speaker 30 ring. As a result, sound is emitted from the sounder 14 at a sufficiently loud and loud sound, and the user operating the PHS terminal device 2
It is possible to listen without touching the opening 12 of the housing case 4 and a nearby person can also listen to a call from the other party at the same time. That is, as shown in FIG. 7, the user can make a voice call via the sounder 14.

As described above, the present invention has been described based on the embodiment. However, this is merely an example, and the present invention can be implemented in various forms without being limited to this example. For example, in the present embodiment, whether or not to use the loudspeaker function can be selected for each of the above four types of modes. However, the use of the loudspeaker function is limited to only the case of the transceiver mode. Only when it is set, the loudspeaker control means 50
Of course, it is also possible to adopt a configuration in which the power is supplied to 6. In that case, the system configuration is simplified, which is advantageous for cost reduction.

Although one of the four modes is selected in step S2 in FIG. 2, it is also useful to enable the use of the loudspeaker call function for all the call modes at once. Yes, such a configuration can be easily realized. In this case, in the display of FIG. 5B, the item of the mode selection may be, for example, "all", such as "public home office transceiver".

Furthermore, when talking in the transceiver mode, it is well known that the frequency of 1ch to 10ch (channel) is used, and when the talking time exceeds 3 minutes, switching to another channel is stipulated. Therefore,
It is also easy to adopt a configuration in which the control unit 24 switches and outputs the audio signal to the amplification units 28 and 36 in accordance with the switching of the channel. In this case, the voice call and the normal call are switched every three minutes, so that a more various usage form can be provided to the user.
