Abstract

A magnetic miniature speaker (230) which has at least one inductive component in series with one end of the coil wire for shifting the resonance frequency of a speaker circuit being located in the radio frequency range. The component(s) is/are supported to the dielectric jacket (234) of the speaker either directly or over a small circuit board (238) fastened to the jacket. Such a speaker can be a part of an integrated antenna module, which has a radiator of the planar antenna of a radio apparatus, and the dielectric part of which functions as both a radiator support and a speaker chamber. Resonances of the speaker circuit, which interfere with the function of the antenna become effectively removed from the operating frequencies of the antenna, because the components of interference elimination are close to the coil of the speaker. Furthermore, there is no need to consider the interference elimination of the antenna in designing the audio part of the circuit board of the radio apparatus, which means savings in the costs of the circuit board.
