Surface audio device with haptic or audio feedback

An apparatus, comprising:

• detection circuitry coupled to a first coil, wherein the detection circuitry is configured to detect a user input on a surface based on a triggering signal comprising voltage or current induced at the first coil by displacement of the surface by a user;
• a top portion comprising a first permanent magnet and a base portion comprising the first coil and a second coil, wherein the displacement of the surface by the user is configured to cause movement of the top portion towards the base portion, and wherein the displacement of the surface is configured to cause relative movement between the first permanent magnet and the first coil to induce the voltage or current at the first coil;
• and
• feedback circuitry coupled to the second coil, wherein the feedback circuitry is configured to activate a feedback signal, in response to detection of the user input by the detection circuitry, and wherein the second coil is configured to cause or alter movement of the surface based on a magnetic field configured to be generated by the second coil upon activation of the feedback signal.
