The singer tells TMZ ... his 15-year-old son, Jahvor -- aka Jah -- is getting ready to drop his first EP with some major help from his favorite producer. Akon tells us Jah will appear on his Konvict label sometime in June. We got a sampling from one of the tracks, called "Locked Away" and it features, of course, Akon.

Goes without saying ... Jah's got his pops' voice.

Ya might be thinking ... Jah's song is about his dad doing time behind bars back in the late '90s and early 2000s, but you're dead wrong. Akon tells us, "My son wrote the chorus and his verse to symbolize how a kid could be mentally 'locked up' and can't escape the inevitable ways of the streets [and] becoming a product of the environment."

Deep stuff.

Akon's kids are incredibly talented. His other son, Ty Pittman, was recently featured on MattyBRaps' "Let's Dance" track. It's already racked up over 500k views on YouTube.

As for Jah ... Akon says he's aiming for a June release because that's African-American Music Appreciation Month.
