Abstract: A charger includes: a hearing aid main body on which hearing aids are placed; a first feed coil that generates a first magnetic flux for performing electric-power feeding to the hearing aid; a second feed coil that generates a second magnetic flux for performing electric-power feeding to the hearing aid; and an electric-power transmission side controller that controls currents that are supplied to the first feed coil and the second feed coil such that the first magnetic flux and the second magnetic flux have inverted phases from each other.

Abstract: Telephone apparatus in that a front cover 3 and a rear cover 4 are combined with each other to form a main body 2, and various components are provided in the main body 2. The front cover 3 includes a transmitter 5, an operating unit 6, a display unit 7, and a receiver 8 from the bottom of the main body 2. In the front cover 3, a main tone hole 85 is provided in the vicinity of a speaker 82, and a sub-tone hole 86 is provided below the speaker 82.

Abstract: The timing controller receives a clock signal and a synchro signal outputted from a transmission side device, and a clock signal and a synchro signal outputted from a reception side device, and detects a writing timing of the transmission side device from these signals, thereby once storing the audio data, which is serial data, into a data storage through a serial-parallel converter, or detects a reading timing of the reception side device of the timing controller, thereby outputting the audio data stored in the data storage as serial data through the parallel-serial converter. In this constitution, adjusting deviation of phase between the devices, audit data can be transmitted.
