対しても迷惑を与える場合があるという欠点があった。However, even though the receiver has the opportunity to go to various places depending on its owner, such as a quiet place like a library or a noisy place in the city, as mentioned above, the receiver always receives a constant signal. There is a drawback that a Pell sound is output, and depending on the location, the ringing tone may be a nuisance not only to the caller but also to those who are nearby.

のできる無線個人呼出用受信機を提供することにある。(Object of the Invention) The object of the present invention is to enable a receiver to detect the surrounding ring tone volume and automatically change the operating level of the ring tone, thereby emitting a ringing sound of a volume suitable for the surrounding environment. An object of the present invention is to provide a wireless personal calling receiver that can perform the following functions.

る。FIG. fJ/c1 is a block diagram showing an embodiment of a wireless personal calling receiver according to the present invention. In the figure, 1 is a calling signal terminal, and 2 is a noise input terminal. When a radio wave containing an individual number corresponding to the receiver is emitted from the base station, reception of the radio wave is detected and input to the call signal terminal 1. When the tone excavator 4 is activated, the noise detector 6 is also activated, and the noise level around the receiver is taken in from the terminal 2 and detected.
この情報は増幅率制御部７に伝達され、増幅率制御部７

音亦はとんどない場合は増幅器５の増＠率が抑えられる
。This information is transmitted to the amplification factor control section 7, and the amplification factor control section 7
uses this detection information to set the amplification factor of the amplifier 5 which receives the output of the tone oscillator 4 as an input. When the surrounding noise is large, the amplification factor of the amplifier 5 is set to a large value, and conversely, when the surrounding noise is very low, the increase factor of the amplifier 5 is suppressed.
この結果、スピーカ３からは周囲の騒音レベルに適応し
たレベルの呼出トーンが出力される。As a result, the speaker 3 outputs a ring tone at a level that is appropriate for the surrounding noise level.

め所持者が安心して利用できるという効果がある。(Effects of the Invention) As described above in detail, the receiver according to the present invention can suppress the generation of excessive tones when the surrounding environment is quiet, and will not cause discomfort to the owner and the surrounding people. It disappears. Furthermore, since the tone level is set to a level that cannot be heard in places where loud scratching sounds are occurring, the owner can use the device with peace of mind.
