Gas delivery device and vehicle

摘要

A scent delivery device includes two substrate units and a drive voltage power supply unit. A gap is provided between the two substrate units. The substrate units are placed so that the principal surfaces of their respective substrates face the gap. Each of the substrate units includes a plurality of linear electrodes. The linear electrodes are formed and arranged in the width direction on the principal surface of each of the substrates, and are electrically connected every predetermined period in their arrangement order. The drive voltage power supply unit applies drive voltages having the same repeating pattern to each set of electrically connected linear electrodes, with a predetermined phase difference. This configuration causes the frequencies of drive voltages applied to the respective substrate units to differ from each other, thereby setting the blowing direction to an arbitrary direction.
