A directional sound transmission method executable by an electronic device is disclosed. A camera of the electronic device is activated. A divided area within a detectable range of the camera is recognized. A first detection operation is performed on first character information of a first person in the detectable range. A first three-dimensional (3D) coordinate information of a face of the first person is recognized through the camera, and the first 3D coordinate information is obtained. A first ultrasonic transducer transmitter corresponding to the first person is activated and the sound of the electronic device is sent to the first person.

An electronic device is provided. The electronic device includes a first housing structure including a first microphone, a second housing structure including a second microphone and foldably coupled to the first housing structure, a sensor module disposed in the first housing structure or the second housing structure, and a processor in the first housing structure or the second housing structure, operationally connected with the first microphone, the second microphone, and the sensor module, the processor configured to receive a folding event related to the first housing structure and the second housing structure through the sensor module while a specific voice recording mode is performed, identify folding state information in response to receiving the folding event, identify a recording function configuration related to the first microphone and the second microphone, based on the folding state information and the specific voice recording mode, and perform recording by applying the recording function configuration.

A device may include a display, a housing, a base, and a hinge operably coupling the display and the housing. The hinge may be moveable over a range of positions. One or more loudspeakers are disposed in the housing. A motor couples to the housing and is configured to rotate the housing and the display. The base is configured to remain stationary during actuation of the motor. In some instances, the device may include a camera and one or more microphones for determining a position of a user. The motor may actuate in a direction of the user to provide increase audio and/or visual experiences.

The present invention relates to a member for a chair for implementing a multi-channel sound system and a chair including the member, and more particularly, to a member for a chair, the member having a plurality of speakers installed therein to implement a multi-channel sound system and installed in a chair to provide sound environments having a sense of space and a three-dimensional effect to a user who sits in the chair, and a chair including the member.

The present invention contributes to reducing the burden on a user while preventing speeches translated into a plurality of languages from interfering with each other. A translation system comprises a camera that obtains surroundings information; a directional speaker that is movable so as to output sound toward a specified position; a directional microphone that is movable so as to receive sound from a specified position; and a translation apparatus that determines a location of a user from the surroundings information obtained by the camera, moves the directional speaker and the directional microphone toward the location of the user, identifies the language of a speech received by the directional microphone, translates the language into another language to output the translated language from another directional speaker, and retranslates the translation in the another language into the language to output the retranslated language from the directional speaker.

An autonomous vehicle control device controls an autonomous vehicle provided with a warning sound output device. The autonomous vehicle control device prohibits transition to a traveling mode when an abnormality occurs in the warning sound output device. Before traveling, the autonomous vehicle control device may execute sound output control to cause the warning sound output device to output a warning sound, and determine whether the abnormality occurs based on output data of the warning sound output by the warning sound output device.

The present disclosure relates to an apparatus and method for monitoring a space using a three-dimensional acoustic web, and to a method of emitting a plurality of acoustic signals, forming a three-dimensional acoustic web in a monitoring target space based on interference between acoustic waves, and recognizing a situation of the monitoring target space based on a change in measured acoustic signals.

The present disclosure relates to a media playing device. A media playing device according to an embodiment of the present disclosure includes: a body, a speaker, and a controller. The controller is configured to, in response to a user staying at a specific position relative to the body, control the speaker to face the user's head and to play sounds. The present disclosure further relates to a self-service terminal.

In an audio spot formation device D including a speaker unit 1 and a support stand 2 that supports the speaker unit 1, the speaker unit 1 includes a plurality of parametric speakers 1a, 1b, 1c and 1d that divide a sound wave into a carrier wave and a sideband wave and radiate the carrier wave and the sideband wave, and a speaker disposition unit 10 in which the plurality of speakers 1a, 1b, 1c and 1d are disposed, the speaker disposition unit 10 is attached to the support stand 2 at a support unit P, at least one of a height of the support stand 2, an angle of attachment of the speaker disposition unit 10 at the support unit P and a direction of at least one parametric speaker of the plurality of parametric speakers 1a, 1b, 1c and 1d is adjustable, and a position at which an audio spot is formed is adjusted via the adjustment.
