る。(-Problems to be Solved by the Invention) In the above-mentioned conventional portable radio telephone, the ejection sound generating section that generates the ringing tone when receiving a call is directly attached to the main body of the portable radio telephone.
For example, if you carry the phone in a closed object such as a bag or handbag, the disadvantage is that even if the ringer rings, you will hardly be able to hear it if there is ambient noise. be. It is also possible to increase the ringer volume, but this requires a considerable volume, and there is also a way to make the shape of the alarm phone or speaker that generates the ringer louder. However, as a result, mobile radio telephones became larger and became portable devices.
At the same time, it is necessary to increase the signal level to the ringer generator, but due to the general trend of smaller operating voltages, the I/bevel of the saturation of the ringer signal decreases, and the signal level increases. It is becoming increasingly difficult to generate signal levels.
