Claims (5)
- 車両に搭載され、車両搭乗員に対して効果音により情報を提供する効果音吹鳴装置であって、
効果音の出力源となる2つのスピーカと、
前記2つのスピーカそれぞれから効果音を出力させるための周波数信号を生成する制御手段と、を備え、
前記制御手段は、車両搭乗員に伝達する1つの情報を前記2つのスピーカからの効果音によって伝達すると共に、2つのスピーカへの前記周波数信号の出力タイミング及び前記周波数信号の周波数を同じとし、一方のスピーカへの周波数信号のデューティ比又はオン時におけるデューティ比であるオンデューティのいずれか一方を示す音圧制御比を第1所定値から前記第1所定値よりも小さい第2所定値に向けて次第に減少させると共に、他方のスピーカへの周波数信号の前記音圧制御比を前記第2所定値から前記第1所定値に向けて次第に増加させる
ことを特徴とする効果音吹鳴装置。 - 前記制御手段は、さらに、前記効果音の音圧及び前記周波数信号の周波数を同じとし、一方のスピーカへの周波数信号の前記出力タイミングと他方のスピーカへの周波数信号の出力タイミングとを重複させつつ、他方のスピーカへの周波数信号の前記出力タイミングを一方のスピーカへの周波数信号の出力タイミングよりも所定時間以上遅延させる機能を有する
ことを特徴とする請求項1に記載の効果音吹鳴装置。 - 前記制御手段は、さらに、2つのスピーカへの前記周波数信号の周波数を同じとし、一方のスピーカへの周波数信号の前記出力タイミングと他方のスピーカへの周波数信号の出力タイミングとを重複させつつ、他方のスピーカへの周波数信号の前記出力タイミングを一方のスピーカへの周波数信号の出力タイミングよりも所定時間未満遅延させる機能を有する
ことを特徴とする請求項1に記載の効果音吹鳴装置。 - 前記制御手段は、さらに、一方のスピーカへ周波数信号を出力した後に他方のスピーカへ周波数信号を出力する動作を繰り返し、且つ、一方のスピーカへの周波数信号の前記出力タイミングにおいて他方のスピーカへの周波数信号の出力を禁止し、他方のスピーカへの周波数信号の前記出力タイミングにおいて一方のスピーカへの周波数信号の出力を禁止する機能を有する
ことを特徴とする請求項1に記載の効果音吹鳴装置。 - 前記2つのスピーカは、車両用の計器が搭載されるメータユニットに配置され、
車両搭乗員に対して警報音により注意を促す情報を提供する
ことを特徴とする請求項1から請求項4のいずれか1項に記載の効果音吹鳴装置。
