In principle, yes, but you wouldn't want to wait around to do the job that way.
Human ears are very sensitive, and the sounds around you carry very little energy
compared to the energy used by common electrical gadgets. One or two watts of
pure tone from a loudspeaker will drive you out of the living room, and the "ear buds"
are blasting no more than a few milliwatts of sound power into your ear canals.
You could hang a microphone out of your window, and use the sounds of traffic
as you drive. It might charge your cellphone in a couple of weeks ... if you leave
the phone turned off and don't use it.

How it possible to call from landline to moble?
When you dial the mobile number, the majority of the call travels by landline. The mobile network knows the physical location of the mobile handset. Once the call cannot travel by wire any closer, it's broadcast onto the mobile network by a microwave transmitter. It's then relayed from mast-t-mast until it's close enough to the handset to relay directly.
Why the input voltage is called Vcc in IC's?
Because it supplies them with the energy necessary for their work. IC's cannot work without energy. If they could we shouldn't put batteries into mobile devices and shouldn't connect computers to the grid. Everything could work just out of thin air.
Can a motor run by its own power generated by itself?
I suspect what you're thinking of is a machine that generates more than 100% of the power it uses, which does not exist (and is in fact impossible according to the conservation of energy).

Power Generators for Convenience?
Power generators convert mechanical energy to electrical energy. The many types of power generators have residential and commercial uses. Most popular of power generators is the mobile portable generator. Due to mobility, campers use portable generators for power in remote areas. Also, portable generators make power available for activities like tailgating where no electrical hookups exist. Increasingly, portable power generators are assisting homeowners in weathering storms during power outages.
