after reading my considerations....

does the red phrase .....

claim 1....a speaker coupled to the control circuitry for playback of recorded digital information; and a power source coupled to the control circuitry for supplying electrical power to the device.

Claim 19...."a speaker coupled to the control circuitry for playback of recorded digital information; and power source coupled to the control circuitry for supplying electrical power to the device."

need modification?

All devices have a power supply....Patent apps or published articles indicating that they have a power supply and not indicating how that power is distributed should not be a challengeable issue of a patent that does in fact describe its distributive power conditions.
