PROBLEM TO BE SOLVED: To provide an acoustic device capable of outputting bass sound and suppressing an acoustic echo due to the bass sound even when sound is input to a sound input unit simultaneously with the output of sound.SOLUTION: An acoustic device 1 includes a front side housing 31 and a rear side housing 32. A speaker and a microphone are exposed forward in the front wall part of the front side housing 31. A passive radiator 5 is exposed backward in the rear wall part 54 of the rear side housing 32. An upper side guide part 81 and a lower side guide part 82 extending in a horizontal direction while vertically holding the passive radiator 5 between them are arranged in the rear wall part 54. A vibration suppression member 7 is slidable along the upper side guide part 81 and the lower side guide part 82. Thus, the vibration suppression member 7 is slidable between a suppression position where the vibration of the passive radiator 5 is suppressed and an open position where the vibration is not suppressed. |
