Abstract

1,143,259. Microphone support. S. G. BROWN Ltd. and T. D. IBBOTSON. 15 Aug., 1967 [25 Nov., 1966], No. 52955/66. Heading H4J. A microphone assembly for attachment to a crash-helmet or other headgear comprises a length of resilient tube 21 with the microphone transducer contained within an expanded part of tube towards one end of the latter, a flexible cord 22 running through the length of the tube being used for attachment to the headgear. The microphone assembly is particularly useful in association with the receiver assembly described in Specification 1,100,749. In the Fig. 2, embodiment, the cord 22, of silk, for example, is looped round a grommet 18 at one end and at the other is wound round a rubber cleat 25 fitted on to a plastic plate 26 attached by grommet 18 to the headpiece receiver assembly. The thin end of tube 21 is open and when the helmet is worn, is adjacent the wearer's mouth. The microphone, held tight in the other end of the tube, has a lead 28. In another embodiment, Fig. 4 (not shown), the quick release arrangement provided by the cord 24 and cleat 25, is replaced by a rubber plug (45) attached to the end of the cord, the plug being insertable into a resilient open tube fixed to the headpiece.
