Can anybody show me a shcematic drawing of the circuit
When a person charges a cell phone they are charging the battery in the cell phone.
Cell phone batteries generally are a lithium ion type.
The current going to the lithium ion battery must be carefully regulated.
Charging too fast (current too high) can cause the battery to overheat, catch fire or even explode.
If the battery is in the cell phone while being charged, the cell phone itself could be damaged.
Regulating DC output from a dynamo requires zener diodes,
capacitors and a nontrival circuit design.
