摘要： A motor includes (a) a cylindrical frame made of ferromagnetic material, (b) a pipe fitted in and disposed within the frame concentrically, (c) a sintered bearing press-fitted into the pipe, (d) a cylindrical magnet fixed on an outer wall of the pipe at an inner wall of the magnet, and (e) a cylindrical coil facing the magnet via an annular space, where the frame and the pipe are welded at a fitted section therebetween. This structure allows the motor to withstand a strong enough shock. An apparatus requiring a vibration motor can employ this motor having a large vibrator, so that great vibrations are available for the apparatus. As a result, the apparatus—utilizing the great vibrations as various functions—is obtainable.

摘要： A motor includes a stator and a rotor facing the stator. The rotor has a magnet and an eccentric weight. The magnet is magnetized in a rotational direction and produces driving magnetic field. The eccentric weight is made of the material having a greater specific gravity than the magnet. The magnet shapes in a cylinder and a part of the cylinder is cut away to form a space. The eccentric weight is placed in the space. A rotational area of the magnet and that of the eccentric weight overlap each other. In this structure, rotation of the rotor spins the eccentric weight, thereby producing large vibrations. The eccentric weight is accommodated by a motor housing for the safety. The thin and compact motor is thus obtainable.

摘要： A slim motor good for a portable device includes a frame, pipe, magnet, coil, shaft, first bearing and a second bearing (inside bearing). The pipe is disposed on an inner wall of the cylindrical magnet, and an outer diameter of the second bearing is set at approx. the same as that of the pipe. The second bearing is aligned to the pipe in an axial direction and fixed on the inner wall of the magnet. This structure allows the magnet to extend axially long enough, and solves conventional problems including power consumption, slant of the shaft, motor efficiency, productivity and the like, thereby contributing to achieving a slimmer motor and a slimmed-down device.

摘要： An electromagnetic vibrator includes a vibration generating mechanism; a case for containing at least part of the vibration generating mechanism; a power supply terminal for supplying power to the vibration generating mechanism, protruding from the case; an elastic body covering at least part of the case; and an elastic pressing body deformable under pressure, formed in part of the elastic body. When the electromagnetic vibrator is incorporated into a device, part of the device presses the case. Correspondingly, the elastic pressing body presses the power supply terminal toward a power supply land disposed on the device side, and the power supply terminal contacts the power supply land thereby electrically connecting itself to the power supply land. With this construction is provided a highly reliable electromagnetic vibrator and device incorporating the electromagnetic vibrator with electric connections having high vibration resistance and impact resistance.
