A system recognizes a gesture of bringing a mobile electronic device to a user ear. The system may be integrated in the mobile electronic device and is provided with a movement sensor which provides a movement signal indicative of the movement of the mobile electronic device. A pressure sensor provides a pressure signal indicative of a pressure acting on the mobile electronic device during the movement. A processing stage performs a joint processing of the movement signal and of the pressure signal in order to recognize the gesture.

Headphones include a digital signal processor (DSP) that processes sound into binaural sound that externally localizes to a user wearing the headphones at a sound localization point (SLP) in empty space at least one meter away from a head of the user. A microphone receives a voice command that executes to change the sound from playing as the binaural sound that externally localizes to the user at the SLP in empty space at least one meter away from the head of the user to playing as stereo sound.

Headphones provide binaural sound to a user wearing the headphones. The headphones store HRTFs of the user and include head tracking and a digital signal processor (DSP). The DSP processes sound into binaural sound that externally localizes to a sound localization point (SLP) at least one meter away from a head of the user. The headphones receive head gestures from the user.

A method provides a voice in binaural sound to a user. The method includes designating a sound localization point (SLP) with a handheld portable electronic device (HPED) and tracking the SLP with electronic glasses worn on a head of the user. A processor processes the voice with head-related transfer functions (HRTFs) to generate the voice in the binaural sound that localizes at the SLP at a location in empty space at physical object.

There is disclosed a mobile terminal comprising a body; a display unit disposed on a front surface of the body and having elasticity; a vibration receiver attached to a rear surface of the display unit; a speaker having a higher output than the vibration receiver and configured to transmit sound to a distant location; and a controller configured to vibrate the display unit by driving the vibration receiver according to an audio signal.

Provided are a method for call processing and an electronic device. The method includes the following. Voice data collected by at least two target wireless headphones of the multiple target wireless headphones are received respectively. The multiple target wireless headphones are coupled with an electronic device, and the electronic device is in a call mode. The voice data collected by the at least two target wireless headphones is sent to the other party of a call. Audio data is received from the other party and the audio data is sent to the multiple target wireless headphones respectively.

A mobile terminal includes: a controller, and a piezoelectric excitation portion including a first excitation source, and a second excitation source surrounding the first excitation source, wherein: the controller is configured to control the first excitation source to generate a first vibration driving force and control the second excitation source to generate a second vibration driving force when the mobile terminal is in a handset mode, such that at a position where the second excitation source is located, a first vibration wave generated by the first vibration driving force and a second vibration wave generated by the second vibration driving force have opposite vibration directions, and a vibration amplitude of the second vibration wave is less than or equal to that of the first vibration wave.

An electronic device includes a first non-contact detection sensor, a second non-contact detection sensor, a display, and a controller. The controller determines a first gesture and a second gesture by referring to the first non-contact detection sensor and a second non-contact detection sensor. The controller, when a first window and a second window are displayed on the display, allocates operation of the first window to the first gesture detected by the first non-contact detection sensor, and allocates operation of the second window to the second gesture detected by the second non-contact detection sensor.

Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of adjusting a ringtone volume of an electronic device. In certain aspects, the method includes determining whether a human body is within a proximity threshold of the electronic device using a proximity sensor, in response to a ringtone event. The method also includes using a first ringtone with a first volume to alert a user about the ringtone event upon determining that the human body is within the proximity threshold. The method also includes using a second ringtone with a second volume to alert the user about the ringtone event, upon determining that the human body is not within the proximity threshold wherein the first volume is lower than the second volume.

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.
