Abstract: This speaker system includes: a speaker device that is disposed outside a region of a projection surface on which a display surface of a display is projected, the speaker device functioning as a real sound source; and a reflector that has a reflection surface reflecting a sound output from the speaker device, the reflector localizing a sound image of a virtual sound source within the region of the projection surface. The reflector has an elliptical reflection surface in at least a part of the reflection surface. With this configuration, the sound output from the speaker device disposed outside the region of the projection surface is reflected on the reflector, and a sound image thereof is localized within the region of the projection surface, whereby it is possible to bring a display position of a video into alignment with an output position of the sound. Thus, a comfortable viewing state can be ensured for a viewer.

Abstract: A convex multi-projector light-field display system includes projectors and a convex diffusion screen facing the projectors. The convex diffusion screen and the plurality of projectors share a same center of curvature, such that each projector projects the image at normal incidence to the convex diffusion screen. Projections of the projectors overlap in an optimal viewing area, within which an observer sees images projected by the projectors, and the optimal viewing area and the plurality of projectors are disposed on opposite sides of the convex diffusion screen.

Abstract: In an audiovisual system, in which video is displayed on a screen that does not permit sound to pass through the screen, such as a light emitting diode panel, a high-frequency speaker positioned above an audience seating area can direct sound toward the screen, so that the screen can reflect the sound toward the audience seating area. The high-frequency speaker can be used with one or more low-frequency speakers positioned at or near the height of the audience seating area. The low-frequency and high-frequency sounds can appear to originate from close to the same height, thereby creating a realistic audio image at the audience seating area. A spectral filter can negate the spectral effects of propagation to and reflection from the screen. Suitable time delays can synchronize the high-frequency sound with the low-frequency sound and with video displayed on the screen.

Abstract: A virtual reality theater structure, including a reflection screen which has a view angle of up down 40-360° and left right 120-360°, an effective range for virtual reality, and has a reflection rate of 1.1 gain or more; a projection system for projecting the 2D or 3D image for left eye and the 2D or 3D image for right eye on the reflection screen; and a chair structure that is rotatable up and downward 40-120° and left and rightward 120-360° where each chair is rotated with area of independent range that is separated individually.

Abstract: Screen vibration systems are provided that can vibrate theater screens using acoustical, electromagnetic, or another type of energy while reducing the presence of image artifacts that may otherwise be visible as result of vibrating the screen. In one example of a screen vibration system, the system includes a screen, a permanent magnet mounted to the screen, and a magnetic source positioned with respect to the permanent magnet and uncoupled from the screen. The screen is moveable in response to a changing magnetic field from the magnetic source.

Abstract: An immersive dome includes a number of novel features designed to enhance the performance of the immersive dome over presently-known immersive dome environments. Projectors are mounted in a multi-tier tower, out of sight beneath a viewing platform positioned to provide optimal wrap-around viewing. The projection surface consists of open-cell foam that allows passage of behind-surface sound into the dome while allowing unwanted ambient noise within the dome to escape. A visually-reflective coating, in conjunction with the open cell structure, provides a textured surface that acts as a micro-baffle and suppresses cross-reflection of projected imagery.

Abstract: The present invention provides a multi-projection system for extending a visual element of a main image, the system including a main projection surface on which a main image is reproduced and an auxiliary projection surface arranged around the main projection surface, in which a visual element associated with the main image is displayed on the auxiliary projection surface.

Abstract: Apparatus for dubbing a film from a source language to a target language includes a replay device (1) which replays a film and a control unit (6) which generates an acoustic model of the scene. A dubbing soundtrack on the replay device (1) is fed via a line (2) to an acoustic processor (3). The acoustic processor (3) processes the dubbed soundtrack under the control of the control unit (6) to produce a dubbed soundtrack which is modified to take into account the acoustic environment of the scene. This soundtrack may be recorded on a recording device (5).

Abstract: A cinema sound system for upperforated screens includes for each sterophonic channel a floor positioned direct radiator bass speaker unit radiating into quarter space and an upper frequency speaker unit mounted above the screen. Each upper frequency speaker unit includes a middle frequency driver mounted in a sealed rear enclosure which is attached to the throat of a middle frequency horn. A constant directivity high frequency horn with a high frequency driver attached to a rear end is mounted coaxially in the middle frequency horn. Sharp cutoff active crossover filters divide the input signal into low, middle, and high frequency band signals which are separately power amplified. The middle frequency horn is adapted to function as a direct radiator at a lower end of the middle band and as a sectoral horn above an unloading frequency of the middle frequency horn.

Abstract: An array of sound transducers where sound producing groups made up of one or more of the sound transducers may be separately driven so as to spatially reproduce a live performance. Flat sound transducers having sound producing diaphragms with a reflective surface may be employed so that the collective flat sound transducers may provide an image projection surface. The sound producing groups in the array of sound transducers may also be controlled so that the audio tracks the video or the location of a live performer.

Abstract: An entertainment structure principally intended to comprise a cinematic auditorium. The structure has a horizontally disposed floor or decking support plate on which seating for members of an audience is arrangable and support means on which the support plate is rotatably mounted. Orientation varying means are operable to tilt the support plate, from the horizontal, in a required direction; while drive means are operable to rotate said support plate on said support means about an upwardly extending axis. The structure also includes a drive system operable to actuate said orientation varying means, and control means operable to control actuation of said drive means and said drive system for varying the angular disposition and tilt of said support plate with respect to said axis. In presentation of a cinematic programme, viewers perception of the action is enhanced by such rotation and tilting being synchronized and in concert with visual and aural action of the programme.

Abstract: An open air multiple screen cinema includes projection screens arranged outdoors in a circle or other arrangement about a centrally located automotive van having projection windows in alignment with the screens and housing angularly adjustable sound movie projectors directed through the windows to respective screens. A figure 8 magnetic induction loop is located within the viewing area of each screen and is electrically energized by an audio modulated current controlled by a respective movie sound projector and each of the viewers is provided with a magnetic field responsive receiver and coupled earphones so as to hear only the sound associated with the screen in the proximity of the viewer. The magnetic induction loops may be buried, at ground level, or supported overhead and may be of other configurations.

Abstract: A picture screen comprising an upright standard, a leg unit supporting the standard, a roller adapted to receive a picture screen, a picture screen mounted on the roller and adapted to be unwound from a closed position to an open position, an elongated screen casing for receiving the roller and the screen coupled to the upright standard, and casing extensions integrally formed with the screen casing and each being provided with a speaker mounted therein. The speakers project the sound toward the viewer/listener to provide a lifelike effect with the picture projected on the screen.
