I was playing with a 12V relay and so I wired the relay like this to see what would happen and it became a buzzer. If its mounted on wood it becomes louder.

Rich is right, you need current limiting. A simple transistor will do the job. Also you need to slow down the switching. The 1mF capacitor will do the job.
