A communication device (1, 15, 25, 35) comprising a housing (2) with a housing wall (50) bounding a space (7). The housing (2) comprises a first housing part (3) and a second housing part (4), which are joined along a dividing line (40), whereby a first abutment face (41) of the first housing part (3) abuts a second abutment face (42) of the second housing part (4) along the dividing line (40). A first microphone transducer (8) is arranged in the housing (2). The first microphone transducer (8) comprises a microphone opening (9), which is connected to the space (7). The space (7) is communicating with the surroundings via a peripheral line (47) of housing openings (39) in the outer side (44) of the housing wall (50) arranged along the dividing line (40), and housing channels (46) extending between the housing openings (39) and the inner side (43) of the housing wall (50). The housing channels (46) and the housing openings (39) are provided as recessions (45; 48) in the first abutment face (41). The invention also relates to the manufacturing such a communication device.
