Abstract: Disclosed herein are techniques for determining a wearing position of a boomless headset. An earpiece of the boomless headset can include at least one local talker (LT) microphone and a reference microphone. The LT microphone(s) are disposed substantially in a first end of the earpiece closest to a mouth of a LT when the LT wears the earpiece. The reference microphone is disposed substantially in a second end of the earpiece, furthest from the mouth of the LT when the LT wears the earpiece. A signal strength measurement (SSM) for a local talker audio signal to the LT microphone(s) and a SSM for a signal to the reference microphone are obtained. Signal processing logic can determine whether the earpiece is worn at an incorrect ear based on whether a difference between the SSM for the LT microphone(s) and the SSM for the reference microphone is below a predetermined threshold.

Abstract: In one example, a headset obtains, from a first microphone on the headset, a first audio signal including a user audio signal and an anisotropic background audio signal. The headset obtains, from a second microphone on the headset, a second audio signal including the user audio signal and the anisotropic background audio signal. The headset extracts, from the first audio signal and the second audio signal, using a first adaptive filter, a reference audio signal including the anisotropic background audio signal. Based on the reference signal, the headset cancels, using a second adaptive filter, the anisotropic background audio signal from a third audio signal derived from the first and second audio signals to produce an output audio signal. The headset provides the output audio signal to a receiver device.

Abstract: A multi-sided microphone boot having a front side, a back side, a first lateral side, a second lateral side, and a bottom side. The front side can have a sound tube extending from at least an internal microphone receiving compartment to an external surface of the front side. The back side can form a microphone opening extending from the internal microphone receiving compartment to at least an external surface of the back side. The first lateral side can include at least one protrusion extending from an external surface of the first lateral side. The second lateral side can include at least one protrusion extending from an external surface of the second lateral side. The protrusions can assist in reducing the contact area and/or the number of contacts between the microphone boot and a microphone receiving compartment within a telecommunication device.

Abstract: In one embodiment, an apparatus comprises i) an audio transducer; ii) an audio driver plate having an ear-facing side and a non-ear-facing side; iii) a rigid housing substantially circumferentially surrounding the audio driver plate without substantially covering the ear-facing side and non-ear-facing side of the audio driver plate; iv) a front plate mounted on the ear-facing side of the audio driver plate and spaced apart from the audio driver plate; and v) a fixing gasket affixed to the non-ear-facing side of the audio driver plate. In addition, the front plate is adapted to be compressed against an ear-facing portion of an audio transducer holding device and the fixing gasket adapted to be compressed against a non-ear-facing portion of the audio transducer holding device, whereby the audio transducer is adapted to be held within the audio transducer holding device by compressive force on both the fixing gasket and the front plate.
