Abstract: A method of and a system for synchronizing isochronous audio data frames provided by a USB interface to a clock of a wireless RF communication device is provided. The USB interface and the wireless RF communication device are connected via an I2S link, the method comprising receiving the isochronous audio data frames and the wireless RF communication device clock in a streaming controller, phase locking the isochronous audio data frames to a USB interface clock, counting start-of-frame pulses of the phase locked isochronous audio data frames, comparing the counted start-of-frame pulses with the wireless RF communication device clock to determine a difference signal, the difference signal triggering a synchronization event code when a threshold difference has been reached, rate matching the isochronous audio data frames to the wireless RF communication device clock upon receiving the synchronization event code.

Abstract: 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.

Abstract: A telephone headset apparatus is disclosed. This headset apparatus includes a body having a microphone at one end and a transducer at the opposite end, an earhook, for attaching the apparatus to the ear of the operator, and a mechanism, contained within the body in a movable engagement, for holding the earhook in a frictional engagement that allows for movement of the earhook, with three degrees of freedom. The mechanism is located at a point within the body where upon adjustment of the earhook by the operator (i.e., rotated, tilted, pivoted) the headset apparatus remains properly balanced and within the sound envelope of an operator, for uninterrupted operation.
