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