According to various embodiments, a device may be provided. The device may include: a housing comprising a first engaging member; and a foot comprising a second engaging member. The first engaging member and the second engaging member may be configured to engage in at least one of a first way or a second way. When the first engaging member and the second engaging member engage in the first way, the housing may have a first orientation relative to a pre-determined portion of the foot. When the first engaging member and the second engaging member engage in the second way, the housing may have a second orientation relative to the pre-determined portion of the foot.

In non-limiting examples of the present disclosure, an electrical receptacle is provided. A first transmission tab configured to be electrically connected to a neutral terminal of the electrical receptacle is provided. A second transmission tab configured to be electrically connected to a live terminal of the electrical is provided. A speaker device in electrical communication with the first and second transmission tabs and a speaker grille cover secured to the receptacle cover are also provided. Other examples of the present disclosure relate to systems, methods and devices for influencing resonant modes of one or more vibrating surface, including a mode throttling device and an exciter device.

Provided is a sound reproduction device including a loudspeaker and a superdirective speaker. The loudspeaker is configured so that a sound pressure of audible sound produced therefrom decreases as the sound travels farther away from the loudspeaker. The superdirective speaker is configured so that a sound pressure of audible sound produced therefrom has a peak at a predetermined distance from the superdirective speaker, and is configured to use an ultrasonic wave as a carrier wave. The loudspeaker and the superdirective speaker are positioned such that a loudspeaker sound field of the audible sound produced from the loudspeaker and a superdirective speaker sound field of the audible sound produced from the superdirective speaker overlap with each other at a position of a listener.

The multi-layered maternity band is an apparel item that is adapted for use during maternity. The multi-layered maternity band is a band that is worn around the enlarged abdomen of pregnant women. The multi-layered maternity band is a textile formed from sound absorbing material that protects the infant from exposure to exterior sounds. The multi-layered maternity band is further fitted with speakers that allows for the further use of sound cancelling technology or the playing of music for the infant. The multi-layered maternity band comprises a band, a first hook and loop fastener, a second hook and loop fastener, a pocket, a first speaker, a second speaker, and a signal cable.

The present technology relates to an information processing device, an information processing method, and a program capable of allowing a user viewing a video of a remote location to be aware of presence of a person who is outside of an angle of field of a video in more appropriate form.

An information processing device according to the present technology includes a processing unit, wherein, when, between a first space where a first imaging device and a first display device are installed and a second space where a second imaging device and a second display device are installed, a captured image captured by the imaging device in one of the spaces is displayed by the display device in the other space in real time, the processing unit performs processing to notify first users in the first space that second users are outside of an angle of field of the second imaging device when the second users who are at positions outside of the angle of field of the second imaging device is detected. The present technology can be applied to, for example, a video communication system.

A display device includes: a display panel; a first sound generator on a first surface of the display panel, the first sound generator being configured to vibrate the display panel to output a first sound; and a second sound generator configured to output a second sound. A third sound is a sum of the first sound and the second sound, and a sound pressure level of at least one of harmonic tones of the third sound is less than a sound pressure level of at least one of harmonic tones of the first sound.

Music and home theater ceiling system that optionally replaces any type of equipment of music and home theater of ten channels; the system simplifies in one main ceiling unit and three peripheral devices any kind of device of this range and also allows the user to install, use and distribute a complicated system of this type and allows to change the channel loudspeaker layout in a very simple way just by rotating the main unit installed at the electrical outlet box of the lamp; the invention has a bridged wall switch that allows controlling the main unit device lights without interrupting its operation. The system receives the audio signal via Bluetooth® and decodes all channels to emit sounds and effects in different directions to immerse the listener into a three-dimensional sound during a movie or video playing.

An operation terminal is configured to: determine whether or not a directional microphone and/or a directional speaker of a mobile object is facing toward the operation terminal based on the position and the orientation of the mobile object, a sound picking-up angle of the directional microphone of the mobile object and an output angle of the directional speaker thereof, and the position of the operation terminal; set, when the directional microphone and/or the directional speaker of the mobile object is facing toward the operation terminal, a predetermined threshold as a distance threshold, and determines whether or not a distance between the mobile object and the operation terminal is equal to or shorter than the predetermined threshold; and make, when the distance is equal to or shorter than the predetermined threshold, at least one of the mobile object and the operation terminal reduce the volume of its microphone and/or speaker.

In non-limiting examples of the present disclosure, an electrical receptacle is provided. A first transmission tab configured to be electrically connected to a neutral terminal of the electrical receptacle is provided. A second transmission tab configured to be electrically connected to a live terminal of the electrical is provided. A speaker device in electrical communication with the first and second transmission tabs and a speaker grille cover secured to the receptacle cover are also provided. Other examples of the present disclosure relate to systems, methods and devices for influencing resonant modes of one or more vibrating surface, including a mode throttling device and an exciter device.

A loudspeaker array has a cabinet in which is formed a continuously open circumferential horn for controlling sound produced by a number of transducers which are positioned in the cabinet, at a throat of the horn. The continuously open circumferential horn may 1) improve the power efficiency of the transducers without unwanted aliasing effects in audible frequency ranges and 2) provide vertical control for sound emitted by the transducers by flaring.
