The document describes a device designed to help users locate misplaced items using sound. The device consists of a circuit board and speaker that can be attached to different items. Each speaker emits a unique frequency that can be activated by buttons on a receiver. When an item is lost, pressing the button will make the speaker attached to the lost item emit a sound, allowing the user to follow the sound and locate the missing item. The innovation is that the device allows one receiver to activate multiple trackers with different frequencies rather than a one-to-one pairing of receivers and trackers.
