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.

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.

Aspects of the present disclosure provide an audio output mode adjustment structure that can include a sound output channel communicating an interior and an exterior of the electronic device and an adjusting unit. An opening of the sound output channel is located at the top of the electronic device. The adjustment unit moves relative to the opening of the sound output channel so that when the electronic device outputs audio in a loud-speaking mode, the adjustment unit does not cover the sound output channel, and sound waves propagate in a straight line through the opening of the sound output channel, and when the electronic device outputs audio in the handset mode, the adjustment unit covers the opening of the sound output channel, so that the sound waves propagate toward a display screen side of the electronic device through the opening of the sound output channel.

Methods and systems are described for coordinating multiple calls across multiple devices. The system includes a communication interface configured to be paired with multiple mobile devices while maintaining concurrent communication with the multiple mobile devices. A controller is configured to connect a microphone and a speaker to the first mobile device via the communication interface to transmit and receive audio in a hands-free mode in response to detecting the first call at the first mobile device. The controller is configured to output a first prompt for selection of whether to continue the first call through the communication interface in the hands-free mode in response to detecting the second call at the second mobile device. The controller is configured to disconnect the microphone and the speaker from the first mobile device in response to receiving a first input indicating a selection of exiting the hands-free mode for the first call.

This disclosure provides a speaker control method and a mobile terminal. The method is performed by the mobile terminal, and the mobile terminal includes at least two speakers. The method includes obtaining a use state of the mobile terminal, and determining corresponding audio mode information based on the use state of the mobile terminal, where the audio mode information includes audio modes of the at least two speakers. The method further includes controlling each speaker to work in a corresponding audio mode in the audio mode information.

A display device including a display panel configured to display an image; a touch sensing device configured to sense a touch of an object; a sound driver configured to generate and transmit a first sound driving signal and a second sound driving signal according to first sound data and second sound data; and a sound generator configured to generate a sound according to the first and second sound driving signals, such that a sound pressure level in a first frequency range is between first and second sound pressure levels in a first operating mode and a second operating mode, wherein the display device is in the first operating mode in response to the touch sensing device not sensing the touch of the object, and the display device is in the second operating mode in response to the touch sensing device sensing the touch of the object.

An electronic device includes a flexible display, a communication circuit, at least one sensor, a processor and a memory storing instructions which, when executed by the processor, cause the electronic device to receive a call from an external electronic device through the communication circuit, connect the call to the external electronic device based on a state of the electronic device, recognize a folded state of the flexible display by using the at least one sensor while the call is connected, and change a setting associated with the call based on the recognized folded state of the flexible display.

According to certain embodiments, an electronic device comprises: first housing; a first substrate disposed in the first housing; a second housing; a second substrate disposed in the second housing; a flexible printed circuit board (FPCB) connecting the first substrate and the second substrate; a hinge hingably connecting the first housing and the second housing; a hinge cover covering the hinge, the hinge cover having a microphone hole formed therein; at least one first microphone disposed in the first housing; a speaker disposed in the second housing; and at least one second microphone disposed in the hinge, and configured to collect external sound through the microphone hole formed in the hinge cover, and mounted on a portion extending from the FPCB.

Electronic glasses track head movement of a user with respect to a location in empty space on top of a physical object. One or more processors process sound that externally localizes as binaural sound to the location in empty space on top of the physical object. Speakers in the electronic glasses provide the binaural sound to the user.

An electronic device, according to various embodiments of the present invention, comprises: a first speaker arranged on one side end of the electronic device; a second speaker arranged on the other side end of the electronic device; at least one sensor; and a processor, wherein the processor may be configured so as to receive a first audio signal, acquire a first channel signal and a second channel signal by using the first audio signal, acquire state information associated with the electronic device by using the at least one sensor, correct at least one portion of the first channel signal on the basis of at least the state information, output the corrected first channel signal using the first speaker, and output the second channel signal using the second speaker. In addition, various embodiments are possible.
