PROBLEM TO BE SOLVED: To provide an on-vehicle audio device capable of increasing/decreasing volume in a gradual manner according to vehicle speed even in a region where volume of voice is large.SOLUTION: An on-vehicle audio device includes: control means 54 for controlling volume of voice outputted from a speaker 4; vehicle speed detection part 63 for detecting vehicle speed of a vehicle; storage means 51 in which a first increase rate is stored; volume calculation means 52 for calculating volume in predetermined vehicle speed based on the first increase rate; and increase rate calculation means for, when the volume calculated by the volume calculation means 52 exceeds a volume limit of the speaker 4, calculating a second increase rate which becomes a volume limit at predetermined vehicle speed. The control means 54, when the volume calculated by the volume calculation means becomes equal to or less than the volume limit, controls the volume based on the first increase rate and the vehicle speed detected by the vehicle speed detection means, and on the other hand, when the volume calculated by the volume calculation means exceeds the volume limit, it controls the volume based on the second increase rate and the vehicle speed detected by the vehicle speed detection means.

    【課題】音声の音量が大きい領域でも車速に応じて音量を徐々に増減することができる車載オーディオ装置を提供する。【解決手段】スピーカ4から出力される音声の音量を制御する制御手段54と、車両の車速を検出する車速検出部63と、第1増加率が記憶された記憶手段51と、第1増加率に基づいて、所定車速における音量を算出する音量算出手段52と、音量算出手段52で算出された音量がスピーカ4の音量限界を超える場合に、所定車速で音量限界となる第2増加率を算出する増加率算出手段と、を備え、制御手段54は、音量算出手段で算出された音量が音量限界以下となる場合に、第1増加率と車速検出手段で検出された車速とに基づいて音量を制御する一方、音量算出手段で算出された音量が音量限界を超える場合には、第2増加率と車速検出手段で検出された車速とに基づいて音量を制御する。【選択図】図2
