AI Technical Summary
Technical Problem
Existing audio-visual systems that integrate TV screens as speakers complicate the structure, increase costs, and degrade image quality due to screen vibration when outputting large volumes, affecting the sense of presence and realism.
Method used
An audiovisual device separates the audio band signal component from the center channel audio signal and directs it to be reflected off the monitor screen, using directional speakers to simulate sound emanating from on-screen persons without vibrating the screen.
Benefits of technology
Enhances the sense of realism by making it seem as if sound is directly coming from on-screen persons, reduces costs, and prevents image quality degradation from screen vibration.

Abstract
[Problem] To achieve, at a low cost without affecting the quality of a video, a sense of presence as though a voice is directly issuing from a person displayed on a screen. [Solution] An audiovisual device 1 that reproduces audiovisual data as audio signals of a plurality of channels and a video signal, and that outputs these signals. The audiovisual device 1 separates a signal component of a voice band from an audio signal of a center channel, and outputs the audio signal after separation and the signal component of the separated voice band. An audio speaker 4 receives the signal component of the voice band outputted from the audiovisual device 1 and emits a sound toward a screen of a monitor 2 connected to the audiovisual device 1. The sound emission direction of the audio speaker 4 is set such that the signal component of the voice band emitted therefrom reaches a listening point P due to being reflected by the screen of the monitor 2.
