A method and system for a headset with internal gimbal, where the headset comprises a headband, a headband, and ear cups coupled to the headband, wherein each ear cup may be coupled to the headband utilizing an internal gimbal, which may comprise a gimbal post in an aperture. The gimbal post may comprise a tip that is wider than its base. The tip may be rounded. The headband may comprise headband endcaps at each end of the headband. A headband slide may be coupled to each headband endcap. The headband ear cups may be coupled to the headband via the headband slides. Each headband slide may be coupled to a headband endcap via a headband pivot. The headband pivot may provide rotational motion of the ear cups with respect to the headband. The force on ears of a user of the headset may be spread evenly by the internal gimbals.

A sound outputting apparatus is provided. The sound outputting apparatus includes at least one loudspeaker, and a main body configured to house the at least one loudspeaker. Each of the at least one loudspeaker includes an acoustic transducer configured to generate a sound wave, and a sound guide part configured to directionally output the sound wave via a plurality of openings. A diameter of each of the plurality of openings is increased as a distance from the acoustic transducer increases.

In device having at least one microphone and one or more speakers, environmental sound may be recorded using the microphone, classified and mixed with source media sound to produce a mixed sound depending on the classification. The mixed sound may then be played over the one or more speakers.

A low-profile earbud is disclosed that sits securely within an ear of a user. The earbud includes a protruding portion that passes through a channel defined by the tragus and anti-tragus of the ear. In some embodiments, the protruding portion can take the form of a cable configured to supply power and transfer data to the earbud. In some embodiments, the protruding portion can provide additional space for electrical components and sensors supporting the earbud.

Systems and methods for generating a haptic output from an audio signal having a continuous stream of sampled digital audio data are provided. A haptic processing system receives the digital audio data, analyses the digital audio data for processing and extracts haptic signals for generating a haptic effect through an actuator. The method includes passing the digital audio signal on through dynamic processor(s), adjusting the dynamic range of the digital audio signal, extracting the signal envelope of the audio data, synthesising low-frequency signals from the extracted signal envelope, and enhancing the low-frequency content using a resonator. The haptic output is generated by mixing the digital audio signal with outputs from the different modules of the haptic processing system. An analytics module monitors, controls and adjusts the processing of the digital audio signal at the noise gate module, the compressor module and the envelope module to enhance the haptic output.

A method of processing audio data for replay on a mobile device with a first speaker and a second speaker, wherein the audio data comprises a respective audio signal for each of the first and second speakers, includes: determining a device orientation of the mobile device; if the determined device orientation is vertical orientation, applying a first processing mode to the audio signals for the first and second speakers; and if the determined device orientation is horizontal orientation, applying a second processing mode to the audio signals for the first and second speakers. Applying the first processing mode involves: determining respective mono audio signals in at least two frequency bands based on the audio signals for the first and second speakers; in a first one of the at least two frequency bands, routing a larger portion of the respective mono audio signal to one of the first and second speakers; and in a second one of the at least two frequency bands, routing a larger portion of the respective mono audio signal to the other one of the first and second speakers. Applying the second processing mode involves applying cross-talk cancellation to the audio signals for the first and second speakers.

A sound system includes a seat, a bone conduction system configured to be disposed within the seat, and at least one directional speaker configured to provide audio through directional acoustic delivery contemporaneously with the bone conduction system. The bone conduction system configured to provide audio through bone conduction sound.

The UV-curable coating compositions disclosed herein are provided for use as coatings for plastic (organic glass) substrates, and ophthalmic lenses, in particular. The compositions may be applied by a variety of means, including spin coating and inkjet coating. The coating compositions exhibit abrasion resistance comparable to conventional thermally-cured sol-gel coatings.

A housing is provided for an acoustic device which is worn in the ear. The housing includes two housing shells, which can be connected with one another along a housing connecting line. The housing connecting line extends at most sectionally in one plane. The housing connecting line is predefined such that the housing shells are configured without undercuts. An outer shape of the housing is adapted to a human ear shape such that the housing lies form-fittingly on an inner side of a tragus and on an inner side of a counter-ledge or antihelix of a human auricle, if the housing is arranged in the auricle.
