Abstract
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.
