<p>Provided is an in-vehicle audio device such that resistance from air trapped in the casing is reduced, and reduction in sound wave output due to mutual cancellation of sound waves of normal and reverse phases generated from the diaphragm is prevented. The audio device (1) emits sound waves from a first sound hole (41) located in the casing (40) in accordance with the vibration of the vibration type speaker (20), as well as emits sound waves emanating from the back of the vibration type speaker (20) from a second sound hole (51) located in an operating panel (50).</p>
