Speaker-phone base for a portable telephone

Abstract

A speaker-phone base for supporting a portable telephone electrical interface, in which the interface having an interface electrical power connector and an interface audio connector, includes a base member. The base member defines a portable telephone electrical interface receptacle that is shaped so as to be capable of receiving therein a portable telephone electrical interface. A base electrical power connector is disposed within the receptacle so as to electrically engage the interface power connector when the interface is placed in the receptacle. The base electrical power connector is complementary to the interface electrical power connector and electrically coupled to an electrical power source. A base audio connector is also disposed within the receptacle so as to electrically engage the interface audio connector when the interface is placed in the receptacle. The base audio connector is complementary to the interface audio connector. A speaker and a microphone are each integral with the base member. A speaker-phone audio circuit is electrically coupled to the base audio connector, the speaker and the microphone. The speaker-phone audio circuit is capable of receiving a telephone audio signal from a portable telephone via the base audio connector and capable of causing the speaker to generate sound corresponding to the telephone audio signal. The speaker-phone audio circuit is also capable of receiving a voice signal from the microphone and transmitting a telephone transmit signal to a portable telephone via the base audio connector.
