<p>PROBLEM TO BE SOLVED: To obtain the antenna system of portable information communication equipment which eliminates ear-offensive noise, eliminates the need to pay attention to whether or not the opposite party hear since a transmitter is separated, and is preferable in design by making an antenna serve as a microphone for transmission. SOLUTION: A knob 18 is so structured that a microphone 19 is built in the tip of the antenna 17. When the user uses the portable telephone set 11, the user draws the antenna 17 out of an antenna fitting part 16 as shown by the arrow B and begins to talk with the receiver 15 put on the ear, so that excellent transmission can be performed since the microphone 19 of the knob 18 at the tip of the antenna 17 is positioned right at the mouth. Namely, when the portable telephone set 11 is used, the antenna 17 is drawn out, so it can be considered that the microphone 19 is also drawn out, and the microphone 19 is positioned where the antenna 17 is extended or contracted and reaches out the mouth of the user. Therefore, a means for positioning the microphone 19 at the mouth is not necessary.</p> |
