Abstract:
1. A telephone communications apparatus comprising: a reproducing circuit for reading out a music signal recorded in a recording medium loaded thereon from the recording medium to reproduce the read out music signal; a setting circuit responsive to an operation by an operator for setting whether or not the music signal is to be mixed with at least one of a transmitting signal and a received signal; a mixer for mixing the music signal reproduced with at least one of the transmitting signal and the received signal; a control circuit operative in response to said setting circuit for determining whether or not to enable said mixer to mix; and a decision circuit for determining a sound or soundless period of a speech signal with which the music signal is to be mixed, wherein said control circuit is responsive to a result from said decision circuit to control a mix ratio of the music signal to the speech signal and said control circuit progressively decreases the mix ratio towards a smallest value during transition from the soundless period to the sound period, said control circuit progressively increasing the mix ratio towards a largest mix ratio during transition from the sound period to the soundless period.
