emit...re-exam...

(original phrase initiating the re-exam stays as is) “A power source coupled to control circuitry for supplying electrical power to the device;

(Amendment adding highlight to the above phrase) "wherein the power source is coupled to the switch circuitry; and wherein the switch circuitry includes multiple transistors configured, to enable supply of electrical power to the receiving socket and to enable at least one of the microphone element and the speaker during record and playback functional operations and in response to control signals provided by the microprocessor, and to optionally disable supply of electrical power to the receiving socket, and to optionally enable supply of electrical power to at least one of the microphone element and the speaker"

The 774 patent is more about the ability of the micro-processor considerations in managing circuits with novelty through a dedicated power source, power management and many attributes of combinational device management.....the microcontroller has on board logic for circuit sensing issues, as well as the interfacing software considerations.
