According to one embodiment, a method, computer system, and computer program product for operating a flexible device to maintain a threshold level of audio quality through various changes in the flexible device's bend profile is provided. The present invention may include identifying the bending profile of a flexible device comprising one or more audio devices; and responsive to identifying one or more of the audio devices as occluded audio devices based on the bending profile, operating the flexible device to change the position of one of the one or more occluded audio devices to raise an audio quality associated with the occluded audio device above the threshold level of desired audio quality.

A method for providing directed transmission of sound waves, through modulation on an ultrasonic carrier, may comprise connecting, at least one directed sound source to an audio system, emitting, via the at least one directed sound source, audio from the audio system, wherein the emitting comprises emitting medium frequency audio sound waves and higher frequency audio sound waves. The audio may be selected via a master control unit, which may be operatively coupled to a mobile application. In many embodiments, a first audio selection is configured to be heard only through a first directed sound source, and a second audio selection is configured to be heard only through a second directed sound source.

Provided is a sound bar including: a rear sound signal generating unit that generates a rear sound from an input audio signal; and an output unit that outputs the rear sound generated by the rear sound signal generating unit to a rear sound speaker.

Speaker bracket comprising an attachment body (2) having a pivot column formed within a recessed channel. An arm assembly is provided comprising a tiltable inner arm portion (4) at least partially housed within an outer arm portion (3). The outer arm portion has a pivot channel into which the pivot column is received for connecting the arm assembly to the attachment body (2) and permitting it to swivel about the pivot column. A rotatable assembly is provided comprising an interface plate (6) connected to the front of the inner arm portion (4) and a speaker fixing plate (8) for attachment to a speaker and being rotatably connected to the interface plate (6) through a shaft (9) and fastener. The shaft (9) and fastener are at least partially received within a cavity in the front of the inner arm portion (4).

A loudspeaker system (50) has a front loudspeaker enclosure (10) having at least one front loudspeaker (20) and a rear loudspeaker enclosure (30) having at least one second loudspeaker (40). The front loudspeaker enclosure (10) is in the form of a horn-loaded enclosure. The rear loudspeaker enclosure (30) is in the form of a vented high-pass enclosure.

A sound image localization effect is enhanced to ensure a preferable viewing state in which a sense of unity between an image or video and sound is generated.

A display device includes: a display on which an image is displayed on a display surface; a rear cover arranged on a back surface side of the display; and an upper speaker and a lower speaker arranged between the display and the rear cover and located so as to be separated vertically from each other, in which an upper slit functioning as a passage hole for sound output from the upper speaker is located above the display, a lower slit functioning as a passage hole for sound output from the lower speaker is located below the display, and a vertical width of the lower slit is larger than a vertical width of the upper slit.

A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.

A hands-free intercom may include a user-tracking sensor, a directional microphone, a directional sound emitter, a display device, and/or a communication interface. The user-tracking sensor may determine a location of a user so the directional microphone can measure vocal emissions by the user and the directional sound emitter can deliver audio to the user. The hands-free intercom may induce the user to move to a desired location and/or to stay within a connectivity area. The hands-free intercom may also or instead induce the user to face in a desired orientation. The directional sound emitter and/or the display device may induce the user by explicitly indicating the desired location, by adjusting an apparent source of the audio or video, by changing quality of delivered audio or video based on user position, by producing irritating audio or video, and/or the like.

The present disclosure relates to a display device for generating sound by directly vibrating a display panel thereof, which includes a display panel connected to a surface of the display panel and configured to display an image; and a sound generating actuator, which is fixed to a support structure of the display panel and attached to the display panel to directly vibrate the display panel. In the display device, the progressing direction of the sound coincides with the image output direction in the display device. Therefore, sound localization or sound output characteristics of the display device or set apparatus can be improved, and a separate speaker is not required, the mechanism of the set apparatus can be easily designed, and a thickness thereof can be easily reduced.

Methods and devices are disclosed for attracting animals. A game call speaker system having a body portion, first speaker unit configured to rotate about a first axis, a second speaker unit configured to rotate about a second axis and a memory comprising one or more stored game calls is provided. Rotation of the first speaker unit may be independent of rotation of the second speaker unit. The first axis may be substantially parallel to the second axis. In some embodiments, the game call speaker system is configured to emit the stored game calls over a relatively wide angle (e.g., 360 degrees) relative to the body portion.
