The subject disclosure describes monitoring when a headset is in communication with a mobile communication device, detecting the headset, comparing a name of a caller and a telephone number of the caller against a list of names and telephone numbers previously stored in a memory, determining that the name of the caller or the telephone number of the caller matches one of the names and telephone numbers in the list, determining that the one of the names and telephone numbers is associated with a pre-recorded message that the user previously recorded and stored in the memory, retrieving the pre-recorded message, and performing a text-to-speech conversion on the name and telephone number of the caller to generate a synthesized speech signal spoken text message and sending the synthesized speech signal and the pre-recorded message to the headset. Other embodiments are disclosed.

Various techniques are provided to implement and use an earpiece having an attachment mount. In one example, an earpiece includes an arcuate rib having a lobe disposed on an upper end thereof and configured to engage with a crus of a helix and an antihelix of a user's ear. The earpiece also includes a mount extending from the arcuate rib and comprising a snap clip configured to engage and position an audio device in contact with the user's ear. Other implementations and related methods are also provided.

A noise cancelling headset includes first and second earpieces, each earpiece including a respective feedback microphone, a respective feed-forward microphone, and a respective output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.

Described is a method of hosting a teleconference among a plurality of client devices arranged in two or more acoustic spaces, each client device having an audio capturing capability and/or an audio rendering capability, the method comprising: grouping the plurality of client devices into two or more groups based on their belonging to respective acoustic spaces, receiving first audio streams from the plurality of client devices, generating second audio streams from the first audio streams for rendering by respective client devices among the plurality of client devices, based on the grouping of the plurality of client devices into the two or more groups, and outputting the generated second audio streams to respective client devices. Further described are corresponding computation devise, computer programs, and computer-readable storage media.

This document describes techniques and devices for detecting twist input with an interactive cord. An interactive cord may be constructed with one or more conductive yarns wrapped around a cable in a first direction (e.g., clockwise), and one or more conductive yarns wrapped around the cable in a second direction that is opposite the first direction (e.g., counter-clockwise). A controller measures one or more capacitance values associated with the conductive yarns. In response to detecting a change in the one or more capacitance values, the controller determines that the change in the capacitance values corresponds to twist input caused by the user twisting the interactive cord. Then, the controller initiates one or more functions based on the twist input, such as by controlling audio to a headset by increasing or decreasing the volume, scrolling through menu items, and so forth.

Aspects of the disclosure include a non-transitory computer-readable medium storing thereon sequences of computer-executable instructions for automatically identifying underutilized features of an electronic device, the sequences of computer-executable instructions including instructions that instruct at least one processor to determine whether at least one underutilized-feature trigger is satisfied, identify, based on determining that the at least one underutilized-feature trigger is satisfied, at least one underutilized feature of the electronic device, identify the at least one underutilized feature of the electronic device to a user of the electronic device, and store an indication of the identification of the at least one underutilized feature of the electronic device to the user.

A headset with automatic noise reduction mode switching is provided to enable better call experience when conducting a call. The headset comprises at least one or more earphones, one or more microphones, a processor, and an active noise cancellation circuit, connected at least with the processor. The processor is configured to determine whether a call is being conducted using the headset, and if a call is being conducted, to switch the active noise cancellation circuit from a first ANC mode to a second ANC mode.

The present disclosure relates to an acoustic output apparatus. The acoustic output apparatus comprising: at least one low-frequency acoustic driver that outputs sound from at least two first sound guiding holes; at least one high-frequency acoustic driver that outputs sound from at least two second sound guiding holes; and a controller configured to cause the low-frequency acoustic driver to output sound in a first frequency range, and cause the high-frequency acoustic driver to output sound in a second frequency range, wherein the second frequency range includes frequencies higher than the first frequency range.

A multiplexing circuit, an interface circuit system, and a mobile terminal, to resolve a problem that a charging current significantly decreases when a headset is used during charging of the mobile terminal. In a multiplexing circuit, a first switch circuit transmits a right-channel audio signal on a right-channel transmission end to a first external transmission end; a second switch circuit transmits a left-channel audio signal on a left-channel transmission end to a second external transmission end; when a second on voltage is received, but a first on voltage is not received, an isolation circuit transmits the second on voltage to a third switch circuit; and when the first on voltage and the second on voltage are received, the isolation circuit pulls down the third switch circuit, and isolates a ground end from a second on voltage end.
