装置。A receiving section that receives at least a signal from a broadcasting station, a first variable resistor provided between the receiving section and ground, and a first variable resistor provided between the output end of the first variable resistor and ground. A receiver including a second variable resistor and a speaker that outputs a signal applied from the receiving section via the first and second variable resistors receives specific information from the broadcast station. detection means for detecting whether the specific signal has been detected by the detection means; and a bypass for applying a signal output from the reception section to the speaker without passing through the first and second variable resistors. An automatic volume adjustment device characterized by comprising means.
