    摘要： An integrated audio-visual system is disclosed for delivering an event to one or more spectators. The integrated audio-visual system includes one or more loudspeakers that are positioned behind one or more visual displays to be effectively behind the one or more visual displays to be shielded from the field of view of the one or more spectators. The one or more visual displays are specially designed and manufactured to allow sound associated with the event to propagate from the one or more loudspeakers with minimal acoustical distortion and/or minimum acoustical vibration while presenting a visual representation of the event to the one or more spectators. Moreover, the one or more loudspeakers and the one or more visual displays are situated to be a predetermined displacement from each other to further minimize acoustical distortion.

    摘要： A localized sound projection system can coordinate the sounds of speakers to simulate the placement of an auditory cue in a 3D space. The system can include a plurality of speakers configured to output auditory signals and a sound localization controller configured to control the plurality of speakers to coordinate the auditory signals to simulate an origination location of a patient alarm. The sound localization controller can determine adjusted auditory signals and control a plurality of speakers to output the plurality of adjusted auditory signals. A method for dynamically controlling speaker settings in a medical environment can include determining volume settings corresponding to a speaker, monitoring a level of ambient noise corresponding to a room of a patient, controlling the volume settings of the speaker to reduce or increase a sound level output of a speaker. A patient monitoring system can be configured to physically manipulate medical devices in response to audible commands. The system can receive a plurality of vocal commands from a user and can manipulate various settings after confirmation from a user.

    摘要： Provided is an acoustic system for a user who uses a seat of an aircraft, an automobile, or the like, which reproduces a sound that cannot be heard by surrounding users without using earphones or headphones. An acoustic system including a speaker system that includes at least one speaker unit pair including a positive speaker unit that emits a sound based on an acoustic signal of a predetermined sound source and a negative speaker unit that emits a sound based on an acoustic signal having an opposite phase to the acoustic signal, in which the speaker unit pair is configured such that a surface of the positive speaker unit and a surface of the negative speaker unit located foremost when viewed from a front direction are one plane perpendicular to a ground plane, and an arrangement of the positive speaker unit and the negative speaker unit when viewed from the front direction is parallel to a direction perpendicular to the ground plane, and is configured such that sounds emitted from the positive speaker unit and the negative speaker unit in a rear direction go around in the front direction.

    摘要： The present application discloses an audio device that has an inhibitory effect on sound waves emitted by a near-field sound source within a specified range and has an amplification effect on sound waves emitted from a far-field sound source outside the specified range. The audio device includes a first sound wave sensor to receive a sound wave and output a first signal based on the sound wave; a second sound wave sensor to receive the sound wave and output a second signal based on the sound wave; and a signal processing circuit coupled to the first sound wave sensor and the second sound wave sensor to generate an output signal based on the first signal and the second signal, wherein the audio device's near-field sensitivity to a sound wave is substantially lower than its far-field sensitivity to the sound wave.
