T-62送话器和R-62受话器通过使用廉价材料、减少元件数量和采用适合自动装配的结构.降低了价格,并已实际用作601型电话机的音响部件。在T-62送话器中,用表面涂敷碳涂料的可动电极和碳素材料成型烧制的固定电极,代替了以往的镀金电极。在R-62受话器中,改进了线圈和引线结构,以便适应自动装配的要求。此外,为改善通话侧音当量,变更了回路形式,结果使送话、受话衰减量增加,为此,T-62、R-62的灵敏度都比以往产品约高2dB,以补偿增加了的衰减量。
The T-62 Microphone and the R-62 Receiver have been reduced in price and have been effectively used as acoustic components for Type 601 telephones by using inexpensive materials, reducing the number of components and adopting a structure suitable for self-assembly. In the T-62 microphones, a fixed electrode coated with a carbon-coated movable electrode and a carbon material was used instead of the conventional gold-plated electrode. In the R-62 receiver, the coil and lead structure is improved to accommodate the need for automated assembly. In addition, to improve the call-side tone equivalent, change the loop form, as a result of sending, call attenuation increased, for which, T-62, R-62 sensitivity than the previous product about 2dB, in order to compensate for the increased Attenuation.
