Abstract: An acoustic device comprises a sound generating unit comprising a diaphragm. An acoustic wave at a front side radiates outwards through a sound outlet. A closed cavity is formed at a rear side of the vibrating diaphragm. Volume adjustment regions are provided in the closed cavity, the volume adjustment regions are a sound absorption portion, a porous sound absorbing material is provided on the sound absorption portion, and the volume adjustment regions are a flexibly deformable portion. The closed cavity is divided into first and second closed cavities by a partition. The first closed cavity is adjacent to the diaphragm, the second closed cavity is far away from the vibrating diaphragm. The flexibly deformable portion is at least part of the partition, and deforms flexibly. The sound absorbing material is provided in the first and/or the second closed cavity, and effectively increase the equivalent volume of the closed cavity.
