I know space is a vacuum. but imagine being able to broadcast a message over the world so everyone can hear.

sorry. no can do.
sound waves need material to transfer the energy.
space has no material.
no sound wave can be sent from space

To broadcast a message throught the vacuum of the space you can easily use electromagnetic waves. If your message is transmitted using radio frequencies with potency enough, when reaching the Earth it will be received by radio receivers, as are the common radio transmissions all over the world. But the only waves that can traverse outer space are the electromagnetic ones.
So your idea is feasible, although indirectly.
I apologize for my poor english.

You can use an electromagnetic wave, that travels through the vacuum . A sound wave only travels through substance

technically no, but theoretically, sub-sonic harmonic waves of just a few hertz at phenomenal decibels above 10,000 db could possibly cause vibratory oscillations for unknown distances effecting interstellar particles and possibly sub-atomic particles. After all quantum string theory theorizes that strings vibrate matter into existence!

No, sound waves are elastic...they need support (like air) for propagation. Outer space is total void.

no. unlike light, sound requires a medium to travel
