ABSTRACT:
The handset consists of two parts, i.e. of a smooth upper part and of a lower part including the two cap members accommodating the acoustic transducers (receiver and microphone capsules). The top part is connected to the lower part by means of bayonet joints. The parting-line surface of the upper part is curved more strongly than that of the lower part, thus causing the two parts to be held together under tension.
