Abstract
A fabric item may have control circuitry and input-output devices. A fabric haptic output device may be formed in the fabric item. The fabric haptic output device may be based on an electromagnetic fabric actuator, a piezoelectric fabric actuator, or other actuator formed from fabric. The fabric actuator may have a permanent magnet portion and an electromagnet portion. During operation, signals supplied to a coil in the electromagnet portion may create a magnetic field that moves the permanent magnet portion. Fabric support structures may be used to support an electromagnet or permanent magnet. Fabric springs may be coupled between the fabric support structures and the electromagnet or permanent magnet. The fabric of the support structures, magnetic structures, and springs may be incorporated into a wearable fabric structure, part of a cover or case for a device, a housing structure such as a housing wall, or other fabric structure.
