Abstract
A process for locally linking optical and acoustic signals in an audiovisual apparatus and an arrangement comprising a plurality of electro-acoustic transducers are described. There are known audiovisual apparatuses capable of multichannel sound reproduction, wherein, however, no satisfactory local linkage takes place between optical and acoustic signals. Thus a plurality of electro-acoustic transducers are provided. They are electrically controlled independently of each other, and are arranged in the immediate proximity of an image reproduction device. The different image areas then can be associated with the sound signals, emitted by the respective transducers, and originating from the corresponding locations.

A method for locally linikng optical and acoustic signals in an audiovisual apparatus comprising the steps of;
- arranging a plurality of electro-acoustic transducers including at least a first transducer and a second transducer in the immediate proximity of an image reproduction device of the audiovisual apparatus, the image reproduction device having at least a first image area and a second image area;
- and
- producing sound signals from the first transducer which emanate sound directly from the first image area and sound signals from the second transducer which emante sound directly from the second image area depending on optical events taking place in the first and second image areas.
An audio arrangement comprising:
- a plurality of electro-acoustic transducers including at least a first transducer and a second transducer for locally linking optical and acoustic signals in an audiovisual apparatus having an image reproduction device having at least a first image area and a second image area;
- the electro-acoustic transducers being arranged in the immediate proximity of the image reproduction device and electrically controllable independently of one another, sound signals emitted by the first transducer emanating sound directly from the first image area and sound signals emitted by the second transducer emanating sound directly from the second image area as a function of optical events taking place in the first image area and the second image area.
A device for locally linking optical and acoustic signals comprising a display for the optical signals, and at least one electrostatic transducer including:
- an electrically conductive, transparent counter-electrode applied to an outer display layer,
- an insulating, transparent intermediate layer with a predefined elasticity so that the intermediate layer can experience small variations in thickness, the intermediate layer being next to the conductive, transparent counter-electrode, and
- an electrically conductive, transparent membrane next to the intermediate layer.
