专利汇可以提供Conference talking circuit专利检索,专利查询,专利分析的服务。并且PURPOSE:To attain ease of hearing of conference talking by varying an attenuation factor in response to the voice signal level of a talker while satisfying the ring tone condition. CONSTITUTION:The conference talking circuit is constituted of an input voice power detecting circuit 10 detecting the input voice signal level of each subscriber, a power comparison circuit 11 comparing the output of an N-party voice power detecting circuit 2 and the output of the input voice power detection circuit 10, a variable attenuation circuit 12 attenuating the input voice level in response to the output signal of the power comparison circuit 11, an adder 1 adding signals at each subscriber, an N-party voice power detection circuit 2 detecting the output signal level from the adder 1 and a subtraction circuit 13 subtracting the output signal of the own variable attenuation circuit 12. Thus, since the attenuation is varied in response to the voice signal level of the talker while satisfying the ring tone condition, ease of hearing of the conference talking is attained.,下面是Conference talking circuit专利的具体信息内容。
