Some battery-powered vibrators come with a foam, rubber, or cardboard insert that fits in the battery compartment to keep the batteries in place and prevent them from rattling. If the insert was cardboard, you may have accidentally discarded it while unpacking the vibrator or changing the batteries. If necessary, you may be able to improvise a new one by cutting a piece of scrap cardboard to fit inside the compartment.
