Abstract
Haptic feedback is a key component of human interface devices as it allows for intuitive interaction. A common way to give haptic feedback is via vibrations, depending on either the user’s inputs or the state of the device. One difficulty of such devices, vibration actuators in particular, is the influence of the outside environment on the actuator’s performance. In this work, we show a way to model how the coupling of the outside environment affects the impedance response of a moving magnet actuator for haptic vibrational feedback and to, in turn, extract the properties of the actuator’s surroundings. To achieve this, we derived an electrical equivalent circuit from a linear two-degree-of-freedom mechanical model and calculated the resulting electrical impedance of the actuation coil.
