摘要： By having multiple air passage holes 10c in the housing 1 and by creating a clearance G2 between the outer surface of the yoke 20 and the inner surface of the housing 1, the measurement of the clearance being confined to a range exceeding 0% but not exceeding 2.5% of the inner radius of the housing, the amount of air movement is limited by the clearance G2, and by this means the frequency range within which the desired acceleration can be attained is expanded.

摘要： 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. The yoke and the springs are assembled together within the housing by placing the tabs of the yoke into the corresponding recesses of the springs, fitting the inner rings of the springs around the outer periphery of the yoke, and fitting the outer rings of the springs into the inner diameter of the housing.

摘要： A magnetic circuit unit includes a pole piece, a magnet, and a yoke and a suspension made of a magnetic material. A magnetic gap is formed between an inner circumferential side surface of the suspension and a circumference of the pole piece. Accordingly, it is possible to allow the magnet in the magnetic circuit unit to be thinly constructed. In addition, it is possible to implement a multi-function vibration actuator having a thin structure and capable of obtaining a sufficiently sensible vibration.

摘要： A multifunction-type vibration actuator and a mobile terminal device capable of decreasing the lowest acoustic resonance frequency and preventing breakage of a coil lead as well as improving acoustic characteristics and preventing sound leaks. A portion near the outer periphery of a diaphragm 3 is bent to form a rising portion 3b extending along an inner periphery 1a of a housing 1 toward an open end thereof. This rising portion 3b serves as a corrugation to decrease the lowest resonance frequency and the amplitude of vibration of which a fulcrum is served by the rising portion 3b is not so large as that of the corrugation. Accordingly, the coil lead of a voice coil 4 is not easily broken. Furthermore, an extending portion 3c is formed to extend outward along a flat surface 1b formed at the open end of a housing 1 from a rising portion 3b. This enlarges the entire radius of the diaphragm 3 and improves the acoustic characteristics. Moreover, by arranging a flat surface 1b of a housing 1 parallel to an extending portion 3c of a diaphragm 3, a gasket can easily be attached.

摘要： This invention deals with a portable terminal that reduces extraneous tones in a portable terminal in which is mounted an electromagnetic induction actuator that produces voice signals, a buzzer signal or a low frequency vibration. By short-circuiting the terminal fittings of the electromagnetic induction actuator or by connecting them electrically to amplifiers or to a signal generator that produces a constant voltage signal or a constant-frequency signal, the extraneous tone produced by vibration of the mechanical vibration system of the actuator is reduced.
