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