Technical Examples

A speaker bracket, speaker baffle, and a speaker cover are provided for standardizing speaker box assemblies for television sets having different sized speakers. A speaker box assembly includes a speaker cover having a stepped inverted surface. A speaker bracket is then installed onto the speaker cover using a securing member. A surface of the speaker bracket is then mated with a speaker bore. The speaker bracket can have a stepped inclined surface sized to closely fit inside the stepped inverted surface of the speaker cover. The step of installing the speaker bracket onto the speaker cover then includes fitting the stepped inclined surface of the bracket with the stepped inverted mating surface of the speaker cover. The speaker cover has an elliptical frustum surface having steps that create an increasing circumference at fixed intervals along a length of the speaker box, and includes grooves that run along the length of the speaker box, perpendicular to the steps. The speaker baffle has corrugations formed along a length of the surface.
