Abstract

The hand set is intended for use in telephones and has a microphone and a receiver. The microphone and the receiver are arranged in capsule receptacles which exhibit a distance from one another and are coupled to one another by a connecting element. The receptacle for the receiver forms with its ear piece a reference area which can be arranged at an angle in such a manner that, starting from the reference area, an increasing distance with respect to a longitudinal axis results in the direction of the microphone. The microphone is constructed as a directional microphone, the rear slots of which are arranged in such a manner that, without mechanical pivoting a directional pattern is produced which points towards the human mouth. In the area of the receptacle for the microphone, at least one sound passage opening is provided in the area of a boundary wall. In the area of a speech receptacle delimiting the microphone, an edge extends which is raised above the speech receptacle and encloses areas of the microphone. The edge is interrupted in the area of a direction facing away from the receiver. At least a part of the sound passage opening points in a direction oriented parallel to a normal to the area of the speech receptacle and a further part of the sound passage opening is oriented transversely with respect to the normal to the area. <IMAGE>
