Operation and the like become unnecessary.

As described above, a single stand may be provided with a plurality of mounting portions (insertion portions) having terminals having different numbers of electrodes, and the user may change the mounting portion. good. Further, similarly to the above, the arrangement of the electrodes of each terminal portion may be made asymmetrical left and right, and the user may change the left and right directions.

By the way, in general, portable units of cordless phones and cordless phones are required to be small and light. For this reason, the built-in speaker and the like are also small and lightweight, and there is a limit to the received sound volume that can be increased in a hands-free call.

The built-in speaker, microphone, and the like may have a predetermined directivity according to the purpose of use, or may be attached so as to obtain a predetermined directivity. Often it is not suitable for free calls. However, in order to realize small size and light weight,
It is often difficult to incorporate a separate hands-free speaker or microphone.

Therefore, in the example shown in FIG.
A sound electrode group 20-2 is provided in the same manner as the control electrode 20-1 in the terminal 21c. In this example, the control unit 7
When the control electrode 20-1 is activated (for example, a predetermined voltage is applied), switching to the hands-free mode is instructed based on a predetermined processing procedure (for example, a flowchart shown in FIG. 5). And judge.
