is there a sound projecting device that is only heard directly in front of it?

Make a deep cone shape device with thick sound proof material, then placing a smaller cone shape speaker at the bottom of cone.

take a large parabolic microphone and replace the microphone with a small speaker.
but some of the sound still is there on the sides and back, just reduced a bit.

Not without sound cancellation, which is very tricky. Sound propagates in all directions from all points in space.

Parabolic dishes, called a whispering dishes or acoustic mirrors, project sounds made at the focal point of one mirror to the focal point if the other mirror, so that even the quitest sounds made at one point are perfectly clear at the other
