The main input energy is electrical energy from mains or power sockets; that energy is transferred to light energy for the pictures, and also there is sound energy (For audio), and all these energy are converted right back at heat energy as there is always a loss of energy in every device.
It's a combination of electrical energy that defines the ringing sound, mechanical energy as the speaker or transducer vibrates to cause air movement, and acoustical energy represented by the pressure waves in the air that bring those annoying ringtones to our ears. ;-)
