diameter has been chosen to be approximately six inches which produces a peak in frequency response at a frequency within the normal range of sounds transmitted by telephone communications that peak being at approximately 2 kilohertz although the preferred embodiment of the invention includes a conical recess in the top of the base 12 a variety of other configurations for the base 12 are possible alternative embodiments of the top of the base 12 include a semispherical recess a flat top a pointed convex conical top and a pointed convex conical top with a more acute angle to the upper cone surface than the general conical angle of the base 12 moreover the configuration of the base 12 is not limited to strict conical sides but instead may use any configuration that allows sound to be radially reflected in generally all horizontal directions away from the speaker assembly additionally the assembly may be constructed to direct sound from the speaker in just a few of the circumferential directions finally the terms used in the claims and specification should not be construed in their most limited sense for instance the term 34 speaker 34 should be construed to include any device capable of generating sound from electrical signals and the term 34 cover 34 should include any arrangement that produces an acoustically sealed environment to the rear of.
