all that said......the speaker, though described as a speaker coupled to the control circuitry as noted in the claims....it would be in the flow of events.....

"control circuitry coupled to" speaker

In that, both sides of coupling are represented in the claims.

power source coupled to-----> the control circuitry------> for supplying electrical power to the device.: (flash memory issue)

power source coupled to-----> the control circuitry------> a speaker coupled

power source coupled to-----> the control circuitry------> a microphone coupled

power source coupled to-----> the control circuitry------> a ? coupled

Whatever circuits the micro-processor is directed to engage.
