[0004] In FIG. 3, the first conventional example shows the contents disclosed in Japanese Patent Application Laid-Open No. 1-227535, in which a received selective call signal is detected by a radio receiving section 106, and the detected output is subjected to a waveform shaping circuit 107. To shape it into a square wave. Comparing the self call number stored call numbers according to the square wave and the storage circuit 109 in the comparison circuit 108. As a result of the comparison, if they match, a match signal is sent to the control circuit 122.
Output to Upon receiving the coincidence signal, the control circuit 122 outputs a sound signal and a vibrator drive signal. These two types of signals are selected by function selection switches S1 and S2, which are linked to operate in opposite directions.
That is, when the function selection switch S1 is turned on, the sound signal is amplified by the speaker drive circuit 128 and transmitted to the input / output switching circuit 129 to sound the speaker 132. At this time, the control circuit 122 controls the input / output switching circuit 12
9 outputs a control signal to connect the speaker drive circuit 128 and the speaker 132 to each other. Note that the speaker 132 is a so-called microphone / loudspeaker that can operate as a microphone, that is, a sound collecting function. On the other hand, when the function selection switch S2 is turned on to perform the vibrator function, an intermittent or continuous signal is supplied to the vibrator drive circuit 114, and the vibrator 115 vibrates in a strong or weak state.

The electronic sound generator 240 includes an LED blinker 241 and a vibration generator 242.

The control unit 201 controls each of the transmission / reception unit 202, the telephone function unit 203, and the call signal confirmation unit 204 to make the function as a portable telephone effective. Also, since the mobile phone is a wireless device,
It is provided for performing radio reception and radio transmission.
Further, a telephone function unit 203 enables a dial operation on a normal telephone and transmission / reception to / from a destination, and a call signal confirmation unit 204 indirectly notifies that a call signal from the destination has arrived at the mobile phone. It is necessary to make them recognize. The electronic sound generation device 240 in the call confirmation unit 204 generates an electronic sound so that the incoming call signal can be recognized by hearing,
The D blinker 241 blinks the LED to visually recognize the incoming call signal. In addition, the vibration generator 242 strikes and vibrates the mobile case portion of the mobile phone with an appropriate force, and recognizes the incoming call signal by the tactile sense of the body portion in contact with the vibrated mobile case.

[0008]

In the case of the first conventional example, this conventional wireless terminal is provided with a function selection switch S in advance.
_{When 2} is turned on, the number of rotations of the vibrator motor is digitally controlled according to the strength of the surrounding noise collected by the speaker, and there is noise around and the incoming call is received by the vibrator. If you want to broadcast, there is a problem that the user must be set to turn on in advance the function selection switch S ₂ manually.

Further, in the case of the second conventional example, a setting means for setting whether to use an electronic sound generating device, an LED blinking device, or a vibration generating device as a calling signal in the control section. When the user sets in advance by key input, the ringing signal is selected at the time of an incoming call, so if there is ambient noise and the user wants to operate the vibration generator, There is a problem that the control unit must be set by key input in order to operate the vibration generator.
