Abstract
A haptic feedback signal detection circuit (211-m), a driving control circuit (200), and a haptic feedback apparatus. The haptic feedback signal detection circuit (211-m) comprises: a charge-voltage conversion circuit (2111-m) coupled to at least one haptic detection piezoelectric device (021-m) in a haptic feedback panel (100), wherein the charge-voltage conversion circuit (2111-m) is configured to convert, when a target object is pressed, a charge signal of each of the at least one haptic detection piezoelectric device (021-m) into an initial voltage signal and then output the initial voltage signal; and at least one voltage amplifier circuit (2112-m), wherein the at least one voltage amplifier circuit (2112-m) is configured to sequentially amplify the initial voltage signals into target voltage signals and then output the target voltage signals to a detection output end as haptic feedback signals.
