A teleconferencing device with an easily removable support stand allows users to easily change the angle of the device on a desk. Wall-mounts hidden within the removable stand allow the device to be mounted easily to a wall.

An electronic device according to various embodiments in the present disclosure may comprise a modem, at least one sensor, and at least one processor which is connected with the modem and the at least one sensor and configured to control: determining the distance between the electronic device and a user thereof during the execution of a call application; determining the output intensity of sound data received from another electronic device connected through the call application, as an output intensity corresponding to the determined distance; and outputting the sound data at the determined output intensity.

To enable communication between a plurality of users to continue in a more preferred mode, provided is an information processing apparatus for controlling a mode of second communication via a network between a plurality of users who are targets of interactive communication, depending on a determination result of whether first direct communication is allowed between the plurality of users.

A transmitter modulates an input voice signal to transmit an RF signal. A receiver demodulates a received RF signal to output an output voice signal. A voice level comparator compares a level of an input voice signal obtained by collecting a voice by a microphone with a VOX sensitivity level. A transmission determination unit instructs the transmitter to transmit the input voice signal, when the level of the input voice signal is equal to or greater than the VOX sensitivity level, based on a comparison result by the voice level comparator. A VOX sensitivity level calculator calculates the VOX sensitivity level in a predetermined period until just before the receiver completes outputting the output voice signal, based on an ambient sound collected by the microphone.

A method and a system for adjusting a volume of a conference call are provided. The system includes at least one sub-device and a host. The host respectively connects the at least one sub-device and detects a number of the connected sub-devices. The host adjusts a volume of an original voice signal received from an external device according to the number of the connected sub-devices to generate an adjusted voice signal adapted to each sub-device and provides the same to each sub-device to play. The host also adjusts volumes of the original voice signals received by the host and each sub-device, integrates the adjusted original voice signals into an integrated voice signal adapted to the external device, and provides the same to the external device to play.

During an electronic call between two individuals, a sound localization point simulates a location in empty space from where an origin of a voice of one individual occurs for the other individual.

A smartphone includes a camera that takes a picture of an ear of a user and retrieves at least one head-related transfer function (HRTF) from a database based on the picture. A digital signal processor (DSP) processes the sound to generate binaural sound, and a transmitter transmits the binaural sound to earphones or headphones worn on a head of the user.

A portable communications device comprises an interactive touchscreen display (20) having a transparent outer surface member occupying substantially all of a front surface of the communications device. A casing provides a rear surface of the communications device. The device further comprises an audible sound transmitter and an audible sound receiver arranged so as to receive vocal sounds produced by a user when the device is placed against the user's head. An ultrasonic transmitter (24) is separate from the audible sound transmitter. An elongate aperture (28) has a minimum dimension less than 100 m located between the transparent outer surface member and the casing. A channel connects the elongate aperture and the ultrasonic transmitter so as to permit ultrasonic signals to pass out of the elongate aperture.

Embodiments of the disclosure include methods, apparatus and computer programs for detecting the proximity of an ear to an audio device. In one embodiment, the disclosure provides a system for detecting the presence of an ear in proximity to an audio device. The system comprises: an input for obtaining a data signal from the environment of the audio device; and an ear biometric authentication module configured to: compare one or more ear biometric features, extracted from the data signal, to an ear biometric template; and generate a first output indicative of the presence or absence of any ear in proximity to the audio device based on the comparison of the one or more extracted ear biometric features to the ear biometric template.

An expandable or all-in-one telephone system is designed for seniors suffering from Alzheimer's and other forms of dementia as well as other cognitively challenged individuals. The features and settings are managed by their caregivers through a web browser or a smartphone application. This phone system provides caregivers with peace of mind and care-receivers with an easy-to-use safe system customized to fit their individual abilities and adaptable as their needs change. Accordingly, the system may help seniors retain dignity and independence, while reducing daily stress points for caregivers.
