Abstract: An improved vibrating actuator for notifying the user of a call upon signal arrival by any of a buzzer, a speech and a vibration, and a power supply mechanism thereof. The device has high impact resistance by a magnetic yoke having a flange, a damper material is provided between an oscillation plate and a cover to prevent generation of noise, and a hole is provided in the cover to change acoustic characteristics as required within the same frequency band. As a power supply mechanism for ensuring electrical connection, a projecting electrical connection terminal is provided on the actuator side, and a conductive material touching with the electrical connection terminal is provided as a power supply terminal electrically connected to a power supply section of a circuit board.

Abstract: A highly precise coreless motor with improved precision of assembly in which weight is reduced by reducing the metal parts and reduction of assembly processes and time by means of a smaller number of parts brings down costs. There is a cylindrical external housing 1 with a through hole 1c in a central position in the closed end. A molded resin body 3 is molded into place through the through hole 1c of the external housing 1; one end is a bearing 3a that supports the rotating shaft, and it continues on the coaxial position of the rotating shaft to become a bearing housing 3b that is fitted into place. The molded resin body 3 is the base on which both the rotor and the stator are assembled.
