Classification: CPC G | IPC G

Claim 10:
11. The system of claim 1:
wherein the first multi-layer inductor cooperates with the first magnetic element to form a speaker configured to broadcast audible feedback responsive to magnetic coupling between the first multi-layer inductor and the first magnetic element; and
wherein the controller is configured to, in response to the first fingerprint image deviating from the target fingerprint image:
trigger the first oscillating voltage at a first frequency across the first multi-layer inductor during the first haptic feedback cycle to induce alternating magnetic coupling between the first multi-layer inductor and the first magnetic element and oscillate the cover layer; and
trigger a second oscillating voltage at a second frequency, greater than the first frequency, concurrent the first oscillating voltage during the first haptic feedback cycle to induce alternating magnetic coupling between the first multi-layer inductor and the first magnetic element and broadcast an audible feedback tone from the speaker.
