Abstract: A bellows bearing is a tube body formed by coaxially wrapping a wire. The tube body has a plurality of consecutively arranged bumps and recesses. End edges of the plurality of bumps form a contact portion, and the plurality of recesses forms an oil storage portion. Thus, when a mini rotating device using the bellows bearing rotates, a desirable lubricating, shock-resistant, and debris-removal effect can be achieved, thereby increasing the service life of the mini rotating device.

Abstract: A direct current (DC) brushless vibration motor includes an inductive coil as the stator, and a magnetic element, which has a plurality of coplanar magnetic poles, as the rotor. The inductive coil is a single annular coil formed by a singly-wound conductive wire. The winding area corresponds to two magnetic poles of the magnetic element of the like polarity at opposite sides. The magnetic element has a centrifugal slot to make the gravity center of the magnetic element eccentric from the axis. When current is input into the inductive coil to form a magnetic field, the magnetic element and the magnetic field generated by the inductive coil repulse each other to generate rotation. The eccentric gravity center of the magnetic element can generate the vibration desired.

Abstract: An auxiliary coupling disk for miniature vibration voice-coil motors aims to couple with a magnetic weight element to change the relative position of the auxiliary disk eccentric from the rotational center of the motor so that the magnetic weight element can generate vibration during rotation. The auxiliary coupling disk further can alter the vibration of the motor. The auxiliary coupling disk has at least one removable member located in the eccentric direction opposite to the magnetic weight element. The removable member may be selectively removed according to requirements to reduce the weight that offsets vibration to increase vibration.

Abstract: A DC brushless voice-coil vibration motor, especially a small-sized micro-vibration motor that utilizes inductance coils and a weight object with a plurality of coplanar magnetic poles as the stator and rotor of the motor. The invention comprises a circuit board, at least two inductance coils and a weight object. The weight object is installed on the inductance coil and away from the motor center. It has a plurality of magnetic poles as the rotor of the motor. When current flows through the inductance coil, a magnetic field is generated so that the weight object starts to rotate under the electromagnetic interactions. Since the weight object is off the motor center, the motor gains vibrational energy during the rotation of the weight object.
