In those animals with mobile ears, they are used to point the external ear in the direction of the sound.

In animals with fixed ears (humans, some apes, some bats) who sound locate by phase delay, those muscles are inhibited from moving to prevent confusion in locating sound.

(Yes, some people can wiggle their ears. Call it a throw-back.)
