Abstract

A sound device for television receivers having means emitting or reflecting sound in front of the screen of the picture tube to direct the sound toward a viewer so that the sound can be heard as if it were emanating from the picture screen of the television receiver.

Claims

1. A television receiver comprising a picture tube having a screen for presenting a picture, coil means energized by electrical acoustical signals and mounted proximate said screen laterally offset therefrom, and means in physical contact with said coil means and driven thereby for translating said electrical signals into sound waves, said last-named means comprising a resiliently supported planar light transmitting vibration element consisting of a material selected from the group consisting of glass and plastic serving also as a protective element for said screen and disposed forwardly thereof, said sound waves, by virtue of the disposition of said element relative to said screen, moving in paths substantially perpendicular and in line with and directly forwardly of said screen.
