Abstract
Radio telephone structure where different functions share mechanical parts. The structure employs at least one piezoelectric ceramic element (350, 360) to produce mechanical movement in a component that would be needed in the radio telephone anyway. The mechanical movement generates sound waves or vibration. The moving element may be a plane or part of a plane (311, 312) of a planar antenna. The structure can be applied inverted, in which case the earphone assembly, for example, serves as a microphone. The number of components and/or elements needed in a radio telephone is reduced and the overall space required by the antenna and speaker is reduced.
Claims10
An integrated radio telephone structure, which radio telephone comprises an audio amplifier and at least one planar element for both a first and a second function, said planar element belonging to an antenna in the radio telephone and the second function being periodic moving of said planar element, for which the structure comprises a piezoelectric element attached to said planar element.
