Abstract

One variation of a system for a haptic actuator includes: a substrate; a baseplate; a magnetic element; and a set of spacer elements. The substrate includes: a first layer including a first spiral trace coiled in a first direction; and a second layer. The second layer is arranged below the first layer and includes a second spiral trace: coiled in a second direction opposite the first direction; and coupled to the first spiral trace to form an inductor. The substrate further includes terminals arranged about a periphery of the substrate and coupled to the inductor. The baseplate is arranged opposite the substrate. The magnetic element is: arranged on the baseplate; and defines a first polarity facing the inductor. The first set of spacer elements are: interposed between the baseplate and the substrate; arranged proximal edges of the baseplate; and defines a nominal gap between the magnetic element and the inductor.

Dependent claims

A system for delivering haptic feedback comprising:

a first haptic actuator comprising:
a substrate comprising:
a set of inductor layers defining a first multi-layer inductor;
and
a first set of terminals arranged about a periphery of the substrate and coupled to the first multi-layer inductor;
a baseplate arranged opposite the substrate;
a first magnetic element:
arranged on the baseplate;
and
defining a first polarity facing the first multi-layer inductor;
and
a first set of spacer elements:
interposed between the baseplate and the substrate;
arranged proximal perimeter edges of the baseplate;
and
defining a nominal gap between the first magnetic element and the first multi-layer inductor;
a cover layer arranged over the first haptic actuator and defining a touch sensor surface;
and
a controller coupled to the first set of terminals and configured to, in response to detecting a first input on the touch sensor surface, drive an oscillating voltage across the first multi-layer inductor to:
induce alternating magnetic coupling between the first multi-layer inductor and the first magnetic element;
and
oscillate the substrate and the cover layer relative to the first magnetic element.
