Abstract

227,162. Sykes, A. F. Oct. 5, 1923. Addition to 160,223. Sound-magnifying appliances.-In a telephone instrument having a strip diaphragm, a form of horn collecting from a slit is used and is conveniently made of wood in two pieces split on the centre line. In another form, a horn is used consisting of outer walls 222 and intermediate insertions 223, 224, which may reach the end of the horn or terminate intermediately. In the case of a concentric arrangement, the intermediate insertions 223, 224 are attached to one another and to the outer boundary by fins, but as shown the arrangement is square. Specifications 159,897, 186,658, and 224,936, [all in Class 40 (iv), Telephones &c.], are referred to.
