を特徴とする車載用音響機器の音量制御装置。[Scope of Claim for Utility Model Registration] 1. A vehicle is provided with a front seat speaker that emits sound mainly to the front seat side and a rear seat speaker that mainly emits sound to the rear seat side. An audio device for outputting a signal is provided, and a control means is provided for making a volume change rate of a front seat speaker and a volume change rate of a rear seat speaker different from each other with respect to an operation amount of a volume adjustment device provided in the audio device. A volume control device for in-vehicle audio equipment, characterized by: 2. The vehicle is provided with a front seat speaker that emits sound mainly to the front seat side and a rear seat speaker that mainly emits sound to the rear seat side, and is also provided with a noise detection means for detecting cabin noise. , an audio device is provided that outputs an audio signal to both speakers, and when the noise detected by the noise detection means is equal to or higher than a predetermined value, the volume of the front seat speaker and the rear seat speaker with the louder one is adjusted. A volume control device for a vehicle-mounted audio device, characterized in that a control means is provided for increasing the volume change rate with respect to the operation amount of the means, and decreasing the volume change rate with respect to the operation amount in the speaker on the side where the noise is lower. 3. The vehicle is equipped with a front seat speaker that emits sound mainly to the front seat side and a rear seat speaker that mainly emits sound to the rear seat side, and when the front seat mode is selected by the selection means,
Both speakers form a sound field centered on the front seats, and when the selection means selects the rear seat mode, both speakers form a sound field centered on the rear seats. A control means for correcting the acoustic signal is provided, the audio equipment is provided with an audio adjustment means for adjusting the volume of the speaker, and the control means is provided with a sound adjustment means for adjusting the volume of the speaker when the rear seat mode is selected. 1. A volume control device for a vehicle-mounted audio device, comprising a volume change rate changing unit that makes a volume change rate of a rear seat speaker smaller than a volume change rate of a front seat speaker with respect to an operation amount.
