Abstract
A wirelessly locatable tag may include a first housing member defining a first exterior surface of the wirelessly locatable tag and an interior surface opposite the first exterior surface. The wirelessly locatable tag may further include a second housing member defining a second exterior surface of the wirelessly locatable tag a first antenna configured transmit the wireless signal using a first wireless protocol, a second antenna configured to communicate using a second wireless protocol different than the first wireless protocol, and an audio system. The audio system may include a magnet assembly configured to produce a magnetic field and a coil positioned within the magnetic field and coupled to the interior surface of the first housing member, the coil configured to interact with the magnetic field to impart a force on the first housing member, thereby moving a portion of the first housing member to produce an audible output.
