Abstract: Locating a lost stylus, or other peripheral input device can be made possible by acoustic resonators integrated within housing structures of the stylus. Acoustic resonators can be formed at an end of the stylus opposite its tip, and can include portions of the stylus outer housing that are thinned down to an engineered thickness that has a particular resonant behavior or frequency. In some examples, acoustic resonators can be formed at a cap portion of the stylus, and can include a resonant diaphragm attached to at least a portion of a cap boundary. Cap coverings for the cap portion can optionally have openings to allow ventilation for changes in air pressure generated beneath the covering. In some examples, an electronic device can communicate a location request to the stylus and can cause the stylus to generate an acoustic signal for a specified target detector using the acoustic resonators.
