Abstract

1,117,810. Sets. GYLLING & CO. A.B. 4 Nov., 1966, No. 49565/66. Heading H4J. In a loud-speaking telephone subset, the loud-speaker 6 is supported behind the impulse transmitter 5 by means of a substantially sound-impervious, funnel-shaped member 7 which is fastened to the impulse transmitter's housing (Figs. 3, 4, 5, 8 not shown) or directly to the front panel 2 of the subset. A number of apertures for emitting sound are provided in the panel around the impulse transmitter. The panel may be detachable and may include integrally therewith a dust proof housing for the impulse transmitter (Figs. 6 and 7, not shown).
