Abstract: A coil assembly for integration into a transducer is presented. The coil assembly may include a metal bobbin assembly, a wire coil, and one or more nonconductive printed circuit board (PCB) stiffeners. A speaker that renders micro noise in an artificial reality environment for improving simulated presence is further presented. The speaker may generate a plurality of micro noises based in part on the determined state of the virtual object. The speaker may spatialize the plurality of micro noises, such that the plurality of micro noises appears to originate from the virtual object. A speaker for speaker diaphragm motion detection using optical MEMS sensors is further presented. Optical MEMS sensors are used to optically monitor displacement of one or more portions of a speaker diaphragm. The speaker may be configured to determine that a speaker diaphragm is in rocking mode and move the speaker diaphragm out of rocking mode.
