Telephone to hearing device communication

摘要

A telephone handset (1), e.g. a mobile phone, is equipped with an add-on module (41). Thereby, the module (41) comprises a microphone unit (9a) which is operated instead of the microphone unit intrinsically provided in the handset (1). Further, the module (41) comprises a short-range wireless transmission unit (23a) which is operated instead of a speaker unit (7) which is intrinsically provided in the handset (1). The short-range wireless communication unit (23a) establishes communication with a respective short-range wireless communication unit (19a) in a hearing device (10) as soon as a distance between the telephone handset (1) and the hearing device (10) drops below a predetermined threshold value as detected by a distance detection unit (21).

主权项

1. A method for establishing wireless communication between a telephone handset and a hearing device system comprising at least first and second hearing devices, the first hearing device having a first microphone unit, the output of the first microphone unit being operationally connected to an input of a first speaker unit at said first hearing device, and the second hearing device having a second microphone unit, the output of the second microphone unit being operationally connected to an input of a second speaker unit, the method comprising:
monitoring when a mutual distance between the first hearing device and said telephone handset becomes shorter than a predetermined distance threshold; when the monitoring determines that the mutual distance is shorter than the predetermined distance threshold:
establishing a wireless short-range audio signal communication from said telephone handset to the first hearing device of said hearing device system; andestablishing an input signal to the first speaker unit to be at least predominantly governed by audio signals transmitted by said wireless short-range audio signal communication; and disabling said wireless short-range audio signal communication after a predetermined time span during which said mutual distance between the first hearing device and said telephone handset remains above said predetermined distance threshold.
