Abstract
A haptic actuator may include a base, a field member coupled to the base and that may include spaced apart permanent magnets. The haptic actuator may also include a coil having a loop shape defining a slotted opening therein, and a spring member suspending the coil so that the field member is within the slotted opening and permitting relative movement of the field member and the coil.
Claims22
A haptic actuator comprising:
- a base;
- a field member coupled to the base and comprising a plurality of spaced apart permanent magnets;
- at least one coil having a loop shape defining a slotted opening therein;
- and
- a spring member suspending the at least one coil so that the field member is within the slotted opening and permitting relative movement of the field member and the at least one coil.
2 more elements
An electronic device comprising:
- a housing;
- wireless communications circuitry carried by the housing;
- a haptic actuator carried by the housing and comprising
- a base,
- a field member coupled to the base and comprising a plurality of spaced apart permanent magnets,
- at least one coil having a loop shape defining a slotted opening therein, and
- a spring member suspending the at least one coil so that the field member is within the slotted opening and permitting relative movement of the field member and the at least one coil;
