摘要: The invention relates to an arrangement for improving leak tolerance in earpiece (100) of a radio device. can be applied preferably mobile stations. One idea the is that acoustic volume (111) arranged behind by taking advantage RF shield casing (112, 116) frequency unit By means one form which loads optimally without therefore needing enlarge size In embodiment wall has been formed electronic circuit board (112), components (117) have connected. Then between and external path through holes (113, 114) board.
