Abstract:
The invention relates to a hearing device that comprises a flexible electric connection between device components that are pivotably connected to each other. The electric connection comprises an originally flat flexible circuit comprising one or more electric conductors embedded in a flexible substrate. The flexible circuit comprises a centre portion that is curved in its original, flat state and that in its mounted stage is bent to form a turn such that two curved sections of the curved centre portion emerge that are arranged opposite to each other in two spaced apart planes that essentially are parallel to each other.

Abstract:
In hearing devices, it is known to use sample-rate conversion to adapt the sampling rate of a received digital audio signal to the sample rate applied by the signal processing in the hearing device. The present invention aims to improve in particular the control of the latency caused by such sample-rate conversion. This is achieved in a hearing device (100, 200) comprising a receiver (101), an input buffer (102) and a sample processor (103), the receiver (101) being adapted to receive samples of a digital audio signal and feed received samples as a digital input signal (x(n)) to the input buffer (102), the sample processor (103) being adapted to process the buffered samples (x(n)) to provide samples of a digital output signal (y(m)) such that the digital output signal (y(m)) is a sample-rate converted representation of the digital input signal (x(n)) with a predetermined target sample rate (F y ), characterised in that the hearing device (100, 200) further comprises a latency controller (109) adapted to estimate the quality of reception of the digital audio signal and to control the processing of the buffered samples (x(n)) in dependence on the estimated quality of reception. The invention allows for providing adaptive latency with a short latency when a user is close to the device (108) transmitting the input signal and long latency is thus typically more annoying and with a long latency when the user is farther from the transmitting device (108) and therefore the risk of retransmission is increased.
