Abstract: A linear vibration motor and a linear vibration system include a housing, a moving member, a drive unit including a driving coil and driving magnets, and a bias unit including a biasing electromagnet and biasing magnets. The moving member vibrates in a first direction substantially orthogonal to a winding axis of the driving coil with Lorentz force generated by a magnetic field formed by the driving coil and a magnetic field formed by the driving magnets. The biasing electromagnet and the biasing magnets are disposed such that the same poles substantially face each other, and the moving member is biased in the first direction by a magnetic spring generated from a repulsive force between the biasing electromagnet and the biasing magnets. Moreover, a magnetic spring constant of the magnetic spring varies with variation in a value of a current flowing through a biasing coil.

Abstract: An antenna device includes a power supply coil to which a near field communication circuit is connected, a near field communication coil that is coupled to an antenna coil of a communication target and the power supply coil via a magnetic field and that resonates at the frequency of a near field communication signal, and a non-contact charging coil that is connected to a non-contact charging control circuit and that is coupled to a target coil for non-contact charging. The power supply coil and the non-contact charging coil are provided on the same plane or on planes that are close to each other. The non-contact charging coil is superposed with the near field communication coil when viewed in plan view, and the shortest distance between the power supply coil and the NFC coil is smaller than the shortest distance between the power supply coil and the non-contact charging coil.

Abstract: An antenna of a communication terminal is disposed on a side on which a bottom surface of a reflective plate, which is included in a display, is present. When the reflective plate is irradiated by an LED light source, the antenna cannot be seen from the side on which a display screen of the display is disposed. Accordingly, an antenna coil of the antenna does not need transparent electrodes and can be made of various materials each having a high conductivity. Therefore, the antenna has high sensitivity, low manufacturing cost, and very efficiently performs near field communication with an external device located on the display screen side of the display.
