The speaker includes a case (12) and a speaker unit (16) attached to a plate (14) provided at an opening of the case (12). The speaker is arranged so that the speaker unit (16) is mounted or attached to a floor or support surface such that a space formed by the case (12), the plate (14) and the speaker unit (16) is airtight and so that the back-and-forth motion of a vibrator of the speaker unit (16) generates expansion and contraction of the case (12).
