An acoustic apparatus includes at least two speakers, each of the speakers having a sound producing direction directed to a corresponding ear of left and right ears of a listener; and an enclosure covering a back portion of a corresponding speaker of the speakers. An opening to open the enclosure is provided at a position further away from the corresponding ear than the corresponding speaker of the speakers. An opening area of the opening is greater than or equal to an effective vibration area of each of the speakers.
