    摘要: The present invention relates to an electrical resonator (10), and an array (30) comprising a plurality of the electrical resonators (10). The electrical resonator (10) comprises an inductor coil comprising at least one turn. The at least one turn comprises an outer turn defining an outer coil perimeter (14). The electrical resonator comprises at least one capacitor connected to the inductor coil. The outer coil perimeter (14) comprises four major edges (141). Each of the major edge (141) is substantially linear and arranged on a different edge of a quadrilateral. The outer coil perimeter (14) comprises four minor edges (142) connecting the major edges (141). The array (30) comprises a first plurality of the electrical resonators (10a) arranged in a first layer, and a second plurality of the electrical resonators (10b) arranged in a second layer on top of the first layer. The minor edge (142a) of each electrical resonator substantially abuts the minor edge (142b) of an adjacent electrical resonator in the same layer, and the first and second layer together define a quadrilateral array of the electrical resonators (30), with a centre of each inductor coil in the first layer coincident with the centre of a gap region between inductor coils in the second layer. A method of arranging a plurality of electrical resonators in an array is also disclosed.

    摘要: A wireless power transfer system is provided for mobile charging of one or more listening devices having wireless power receiving antennas couplable to a wireless power transfer antenna. The system includes a case configured for attachment to a mobile electronic device having a wireless power transfer antenna. The case includes a hollow for each of the listening devices, with each hollow being shaped and located to hold a respective listening device in a coupling position with the wireless power transfer antenna of the mobile electronic device when the case is mounted to the mobile electronic device. An attachment may be used to mount the case to the mobile electronic device.
