ABSTRACT:
A telephone set having a telephone set body and a handset unit which incorporate therein a speaker amplifier and a speaker, respectively, and a coil cord interconnecting the speaker amplifier and speaker, the telephone set being selectively usable in an on-hook and an off-hook state. The telephone set is provided with an implementation which, when a conversation is held in an on-hook state, connects the speaker amplifier and speaker without the intermediary of the coil cord to thereby prevent the level of a voice signal from the speaker amplifier from being lowered. In the on-hook state, the handset unit is placed on a cradle. The implementation against the decrease in the voice signal level comprises flat connecting terminals fitted on the bottoms of recesses which are formed in a casing of the handset unit, and flat resilient connecting terminals fitted on the tips of lugs which extend out from a casing of the cradle to mate with the recesses.
