However, in the case of the above-mentioned conventional telephones, especially mobile phones, they are used under various places and conditions. For example, people in the theater or performances or museums crowded with crowds such as museums, etc. In the case of the existing mobile terminal, it is possible to adjust the bell volume, but it is inconvenient for users because the bell volume must be adjusted at any time according to the surrounding conditions as described above. Fixed to a certain volume, using a mobile phone, the bell volume control function was practically a useless feature.

The present invention is to solve the conventional problems as described above, by detecting the ambient noise level according to a specific place, when a predetermined bell signal is input from the outside, the internal microprocessor quantifies the magnitude of the detected noise level, The aim is to provide a device that can output a certain amount of ring volume through the ringer of the mobile phone.

Subsequently, an analog signal of the received noise is output to the BBA 18. The BBA 18 quantifies the analog signal as a digital signal and sends the information to an 80C186EC processor (not shown) inside the MSM chip 19. After receiving the predetermined information, the MSM chip 19 sends an appropriate size signal to the ringer 20 according to the value to ring the bell.
