Abstract

The present invention relates to a monaural wireless headset (20) that may e.g. be connected to a mobile phone by means of a Bluetooth connection.

The present invention provides a monaural wireless headset (20) comprising a housing (21) with a main body (22) and a microphone boom (23), a microphone (27), a wireless transceiver (28), a speaker driver (39) and a rechargeable battery (29). The monaural wireless headset (20) is adapted to be arranged at an ear (1) of a user in a wearing position wherein at least a portion of the main body (22) resides on the inwards side of the crest (7) of the ear'"'"'s antitragus (6) and wherein the microphone boom (23) at least partly extends outside the ear'"'"'s pinna (1) towards the user'"'"'s mouth. The microphone (27) is arranged in the microphone boom (23) and is adapted to receive a voice signal from the user and provide a microphone signal to the wireless transceiver (28) in dependence on the voice signal. The wireless transceiver (28) is adapted to transmit a wireless output signal in dependence on the microphone signal. Furthermore, the wireless transceiver (28) is adapted to receive a wireless input signal and provide an audio output signal to the speaker driver (39) in dependence on the wireless input signal. The speaker driver (39) is arranged and adapted to transmit a sound signal into the ear (1) in dependence on the audio output signal, and the rechargeable battery (29) is adapted to provide electric power to the wireless transceiver (28) and the speaker driver (39).

The monaural wireless headset (20) is characterized in that the speaker driver (39) and the rechargeable battery (29) are arranged in the main body (22) in such a way that the speaker driver (39) and at least a portion of the rechargeable battery (29) reside on the inwards side of the crest (7) of the antitragus (6) when the monaural wireless headset (20) is in the wearing position.

This may provide a monaural wireless headset (20) that allows a comfortable wearing and a secure holding of the headset (20) when in use.

Claims
