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: This invention concerns an electromagnetic induction actuator to be mounted in small equipment such as portable telephones and pagers; also concerns such portable telecommunications equipment. The electromagnetic induction actuator, as well as the portable telecommunications equipment in which it is mounted, can be assembled in a thin and small package even though there are tabs as shock resistance stoppers, and has good acoustical characteristics. In the electromagnetic induction actuator there is a yoke that has tabs as stoppers to provide shock resistance, and there are springs that have inner rings, outer rings, bridge arms that connect the inner and outer rings and recesses that correspond to the tabs of the yoke.

Abstract: There is a terminal block with leaf spring metal terminals that extend downward from a housing on the side opposite the open end of the housing in which a diaphragm is fitted and fixed, and an elastic material functions as a pad that is sandwiched between the surface of a circuit board and the open side of the housing on the side from which the metal terminals project, with the metal terminals pressed against the conduction pattern of the circuit board to make an electrical connection.

Abstract: There is a roughly rectangular housing that is narrower in one direction, with a pair of suspensions having two arms that are located in the narrow space of the housing and attach to the main part that supports the electromagnetic circuit and that extend gradually outward from the attachment on the main part of the suspension in the same or crossing directions, with the tips of the two arms of each suspension set in the narrow walls of the housing, such that the electromagnetic circuit can vibrate in the two suspensions.
