Put horn 28 near your mouth In addition, the directional speaker 27 can be easily located near the ear, and the call can be made in a very natural manner. Even when the case body 1 is attached to the right arm with the band body 33, the same operation and effect can be obtained. This point is the same in the above embodiment.

Further, in the above embodiment, the wristwatch-type telephone has been described as having the clock device 3 housed in the case body 1 and having a clock function. There is no need to have a clock function.

Further, in the above-described embodiment, each function key 11 is connected to each of the dials over the entire circumferential surface 17 of the case body 1. It has been explained that they are arranged at close positions corresponding to the respective keys 10. However, it is always necessary to attach each function key 11 to each It is not necessary to arrange them in close proximity to each of the ear keys 10, for example, as appropriate, for example, at an easily accessible position on the peripheral side surface 17. You can do it. In addition, the number of function keys 11 does not necessarily have to match the number of dial keys 10. Also, if the function of the function key 11 is included in the dial 110, the function key 11 cannot be set. The configuration may be used.

Further, in the above embodiment, the audio input / output unit case 36 is described as being formed in a substantially rectangular shape, but the present invention is not limited to this shape. Any shape is acceptable as long as it is not elongated. In addition, the audio input / output unit Only when a wristwatch-type telephone is used as a telephone, the body 36 may be of a stretchable configuration having a longitudinal shape of an appropriate length.

In the case of this telescopic configuration, when the wristwatch-type telephone is used as a wristwatch, the voice input / output unit case 36 may be connected to other surroundings. This prevents contact with an object and can further improve operability.
