KR970031668A - Ring volume automatic control device of telephone and its method - Google Patents

Abstract

The present invention relates to a device for automatically adjusting the bell volume of a telephone and a method thereof, and the related art bell volume adjusting device has the inconvenience of having to adjust the bell volume by directly operating the bell volume adjusting switch by grasping the surrounding noise environment. there was. Accordingly, the present invention automatically adjusts the ring volume of the microphone to detect the ambient noise, the on / off switch of the microphone, the audio level check unit for checking the audio level from the signal output from the microphone, the control signal of the controller And a bell volume control unit for adjusting the bell volume according to the present invention, and a control unit for overall control of the apparatus and input / output signals; The ring volume automatic adjustment method checks the surrounding sound environment when a ring signal is detected and compares / determines the current state of the bell volume control device and the audio level of the sound environment checked above, so that the setting level is higher than the audio level. When the ring volume control switch is automatically set up and down when the volume is high or low, the bell volume control unit is set to the bell volume corresponding to the noise environment. There is a filial piety.
