A case for a portable electronic device includes a housing, a lid, and a hinge rotatably coupling the lid to the housing such that the lid is operable between an open position and a closed position. The hinge includes a first multipole magnet coupled to the lid such that the first multipole magnet rotates with the lid. A second multipole magnet is coupled to the housing and is arranged coaxially with the first multipole magnet and such that the first multipole magnet and the lid rotate relative to the second multipole magnet. The lid is unstable between the open and closed positions, such that, between the open position and the closed position, the lid is biased toward either the open position or the closed position depending on an angle of orientation of the lid relative to the housing.

A wearable audio device that includes an electro-acoustic transducer for creating audio output and a magnetometer system comprising a magnetic field sensor with an output, a temperature sensor that is configured to determine an internal device temperature, a processor, and memory. The magnetometer system is configured to derive from the magnetic field sensor output a directional heading of the Earth's magnetic field. The magnetometer system is further configured to compensate the magnetic field sensor output, wherein the compensation is temperature dependent. The memory is configured to store temperature-dependent compensation information. The magnetometer system is further configured to use the temperature sensor output to retrieve compensation information from the memory in order to compensate the magnetic field sensor output at the current temperature.

A wearable audio device with a magnetic field sensor that is constructed and arranged to sense the Earth's magnetic field. A magnet in the earphone, for example the magnet of the electro-acoustic transducer, produces a first magnetic field having a first magnetic field strength. A docking or parking magnet in the earphone produces a second magnetic field that is configured to reduce an influence of the first magnetic field on the magnetic field sensor.

Wearable audio device

A wearable audio device with an electro-acoustic transducer that is configured to create audio output. The transducer has a transducer magnet that produces a transducer magnetic field having a magnetic field strength, and a magnetic structure such as a cup that guides the transducer magnetic field. The transducer magnet is on the inside of the magnetic structure. There is a magnetic field sensor outside of the magnetic structure; the magnetic field sensor is constructed and arranged to sense the Earth's magnetic field. A nulling magnet is coupled to or proximate the outside of the magnetic structure and is constructed and arranged to produce a nulling magnetic field that reduces the strength of the transducer magnetic field at the magnetic field sensor.

A wearable audio device with a magnetic field sensor that is constructed and arranged to sense the Earth's magnetic field. A magnet in the earphone, for example the magnet of the electro-acoustic transducer, produces a first magnetic field having a first magnetic field strength. A nulling magnet produces a nulling magnetic field along at least a first nulling magnet axis. The nulling magnet is configured to reduce an influence of the first magnetic field on the magnetic field sensor. The first nulling magnet axis, the first magnet axis, and the first sense axis are aligned.

A headphone includes an electro-acoustic transducer for creating audio output, the electro-acoustic transducer comprising a transducer magnet that produces a transducer magnetic field having a magnetic field strength, a housing constructed and arranged to be positioned at an ear of a wearer so as to direct the audio output at the ear canal of the ear, a magnetic field sensor positioned in the housing and constructed and arranged to sense the Earth's magnetic field, and a nulling magnet positioned in the housing and constructed and arranged to produce a nulling magnetic field that reduces the strength of the transducer magnetic field at the magnetic field sensor.

A portable loudspeaker includes an electro-acoustic driver which creates sound waves when operated and a housing having a front side to which the driver is secured. The loudspeaker also includes a battery supported by the housing for providing electrical power to the driver and a cover having an upper portion and a lower portion, and secured to the housing which can be moved between (i) a closed position in which the upper and lower portions overlie the driver, and (ii) an open position in which the upper and lower portions do not overlie the driver and are substantially disposed beneath a supporting base of the housing. A controller controls operation of the loudspeaker. When the cover is moved to the closed position, the controller mutes the driver if the driver was outputting acoustic waves when the cover was moved to the closed position.

An armature for a linear motor is described. The armature includes a first of a pair of magnetic structures comprising a first plurality of maglettes each having a magnetic polarity vector; an angle between two adjacent magnetic polarity vectors in the first plurality of maglettes having a first magnitude; and a second of the pair of magnetic structures comprising a second plurality of maglettes each having a magnetic polarity vector; an angle between two adjacent magnetic polarity vectors in the second plurality of maglettes having a second magnitude, the first plurality of maglettes including a first outer maglette that is adjacent to a second outer maglette of the second plurality of maglettes, an angle between the magnetic polarity vectors of the first and second outer maglettes having a third magnitude that is different than at least one of the first and the second magnitudes.
