Abstract
A telephone handset having a receiver housing at one end has a flux coil positioned at the front corner at the junction between the peripheral wall and the front wall of the housing. The flux coil is connected in series or in parallel with the receiver. The flux coil, by this arrangement, is positioned very close to the front face of the receiver housing, giving very good coupling between flux coil and a hearing aid. Normally unused space is occupied by the flux coil and permits use of any convenient receiver.
