    Abstract: An acoustic device includes a waterproof vibrating membrane and a magnetic component disposed below the waterproof vibrating membrane. The waterproof vibrating membrane includes a convex portion which protrudes toward a position of the magnetic component, or a concave portion which is recessed opposing to a position of the magnetic component. The magnetic component includes a concave pressure buffering portion corresponding to a shape of the convex portion of the waterproof vibrating membrane wherein the concave pressure buffering portion is recessed toward a side opposing to a side on which the waterproof vibrating membrane is located, or a convex pressure buffering portion corresponding to a shape of the concave portion of the waterproof vibrating membrane wherein the convex pressure buffering portion protrudes toward a side on which the waterproof vibrating membrane is located.
