I have a simple rc car that include a component speaker and amplifer ic with a button on the remote control when you press it , a song starts .
so I want to understand how songs can be saved on this cars (wich components) , and how can i transfert it in my simple project (rc car)

That looks like an old board. Is that a small vertical board in the middle with a black blob on it? If so, that's probably what generates the tune and it will be very difficult to find any information on it.

Edit, can you read a number on the 8 pin chip that's top right?

TDA2822M amplifier.

I agree, the TDA2822M is the audio amplifier, the song will be stored on the small vertical board using a COB device (Chip On Board).

Probably the easiest option would be to get a small MP3 player board, then you can play anything you care to store on a micro-SD card.

There is an audio jack too

Sorry, that is old technology and not worth trying to understand and, probably, can only play one tune. Do as Nigel says and get an MP3 player. If you can code then you can get all this up and running very easily and cheaply.
