In a car-mounted speaker device, a speaker system installed on the rear tray inside the vehicle, a correction speaker installed at a position different from the installation position of this speaker system, and an input to the speaker system. A bandpass filter is connected to input the audio signal produced by the speaker system, and its output is supplied to the correction speaker. An in-vehicle speaker device comprising: control means for controlling a bandpass filter so as to supply an audio signal in a frequency band corresponding to the dip frequency to a correction speaker. 2 Automatically detects the dip frequency that occurs when the sound played by the speaker system is reflected by the rear window, and controls the bandpass filter using a control signal based on this detection signal to filter the frequency band corresponding to the dip frequency. The vehicle-mounted speaker device according to claim 1, characterized in that the audio signal is configured to be supplied to a correction speaker. 3. The vehicle-mounted speaker device according to claim 1, wherein the correction speaker is installed at a corner of the rear tray. 4. The vehicle-mounted speaker device according to claim 1, further comprising a power amplifier that amplifies the output of the bandpass filter and an amplifier that amplifies the audio signal input to the speaker system.
