Abstract: A vibration motor having an insulating housing, a bidirectional coil and a magnetic ring is provided. The insulating housing is of cylindrical shape and at least three position-limiting ribs are protruded from an internal surface thereof. Each position-limiting rib is extended parallel to a central axial line of the insulating housing. The insulating housing has a pair of end plates on two ends thereof. The end plates are made of insulating material. The bidirectional coil is accommodated in the insulating housing and spaced apart from the internal surface of the insulating housing. The magnetic ring is movably accommodated in the insulating housing, and the magnetic ring is arranged coaxially with the insulating housing to surround the bidirectional coil. The position-limiting ribs are disposed adjacent to the magnetic ring and surround an outer edge of the magnetic ring.

Abstract: A flow stabilizer includes a base, a noise reduction structure, and a plurality of protrusion structures. The noise reduction structure is disposed on the base. The protrusion structures are disposed between the base and the noise reduction structure. The protrusion structures define a plurality of intervals, and at least two intervals are not equal.
