ベル音量制御回路。[Claims for Utility Model Registration] (1) A response circuit that outputs a signal in response to a calling signal from a telephone line, and a sound generating means that generates a ringing tone based on the signal from the response circuit;
comprising a changing means for changing the volume of the ringing tone generated by the sounding means, and a detecting means for detecting day or night,
A bell volume control circuit characterized in that when the detecting means detects that it is night, the changing means is operated to make the volume of the sounding means lower than when it is not night. (2) The bell volume control circuit according to claim 1, wherein the detection means is capable of setting and changing a reference value for detecting whether it is night or not. (3) The detecting means is a timer capable of distinguishing between day and night, and when the timer detects a predetermined time, it is assumed that it is night and the changing means is operated. The bell volume control circuit according to item 1 or 2. (4) Claim 1 of the utility model registration claim, characterized in that the detecting means includes means for detecting brightness, and when the brightness is below a predetermined value, it is assumed that it is night and the changing means is operated. The bell volume control circuit according to item 2 or 3.
