Haptic and Audio Effect of a Coil Actuator

Abstract

A capacitance module may include a stack of layers, a set of capacitance electrodes disposed on a surface of the stack, a first actuator, including an inductance coil disposed on at least one surface of the stack and a magnetic field source positioned to at least partially overlap with the inductance coil, a processor in communication with the set of capacitance electrodes and the first actuator, and memory in communication with the processor. The memory may contain programmed instructions that cause the processor, when executed, to generate a composite drive signal having a haptic component and an audio component and drive the first actuator with the composite drive signal. The haptic component may have a lower center frequency than the audio component.

Dependencies are inferred from the claim text.
