Abstract: A system and method for supplying power to a headset, and for transmitting multiple signals generated in the headset to a terminal using frequency division multiplexing. An audio signal and a carrier signal are generated in the terminal and summed together to form a composite uplink signal. The composite uplink signal is provided to a headset over a first physical channel. At the headset, the audio and carrier signals are separated, and the carrier signal is used to generate power in the headset. Signals generated by a plurality of acoustic sensors in the headset are combined using frequency division multiplexing to generate a composite downlink signal, which is transmitted to the terminal over a second physical channel. One or more carrier signals used to generate the composite downlink signal are provided by either a carrier source in the headset, or by recovering the carrier signal from the composite uplink signal.

Abstract: A headset assembly with a recording function for communication includes a left earphone, a right earphone, a call module, and a recording module. The left and the right earphones respectively have a speaker and a microphone. The call module is electrically connected to the left or the right earphone. The recording module is electrically connected to the left and the right earphones. In a first operation mode, the call module communicates with an external communication device through the microphone and the speaker of the left or the right earphone. In a second operation mode, the recording module receives an ambient sound signal through the microphones simultaneously, and records and stores the ambient sound signal. As the microphones are placed in a left auricle and a right auricle, recorded sound may have an effect of a head-related transfer function (HRTF), thus achieving an effect of a stereo sound field during playback.

The microphone arm (3; 103; 203) is connected to a hinge member (4; 104; 204), which is pivotally connected to the housing (2; 102; 103) such that the microphone arm (3; 103; 203) can be rotated about a first pivot axis (P1; P101; P201) between a first position, in which it lies along a first surface (9; 109; 209) of the housing (2; 102; 202) and a second, extended position in which it extends away from the housing (3; 103; 203). The headset is further provided with a switch (19), which is operably connected to the microphone arm (3; 103; 203) or the hinge member (4; 104; 204), such that a rotation of the microphone arm (3; 103; 203) from the first position to the second position or vice versa activates the switch (19) and changes headset mode. The microphone arm (3; 103; 203) is movably connected to the hinge member (4; 104; 204) so that the microphone arm (3; 103; 203) can be moved into a third position, in which it lies along a second surface (10; 110; 210) of the housing (2; 102; 202).

Abstract: A light weight and comfortable ear mount for a personal audio-set is disclosed. The ear mount conforms with the antihelix of a wearer's ear, thereby operating substantially as a compression spring between the wearer's antihelix and tragus, to operably secure the personal audio-set in place. In a preferred embodiment, the ear-mount is substantially kidney-shaped and includes an opening to prevent the total occlusion of the ear canal by the personal audio-set. Alternatively, the ear-mount includes a loop of material sized to operably engage the antihelix of the wearer's ear. The ear-mount is preferably reversible to allow it to be placed in either the wearer's left or right ear.
