A headphone comprising: two headphone earcups each comprising: an earcup housing defining an active chamber that acoustically couples a sound output side of a speaker to an ear of a user, and an inactive chamber that surrounds the active chamber; and a passive valve assembly configured to open in response to a positive pressure and a negative pressure within the active chamber to fluidly couple the active chamber to the inactive chamber and equalize a pressure between the active chamber and the inactive chamber.

A stretchable fabric signal path may include a conductive strand located between first and second outer fabric layers. The outer fabric layers may be formed from intertwined strands of elastic material. The conductive strand may have a wavy shape to accommodate stretching of the stretchable fabric signal path. First and second inner fabric layers may be located between the outer stretchable fabric layers. The inner fabric layers may be formed from intertwined strands of non-elastic material. The inner fabric layers may have strands that are intertwined with the outer fabric layers to serve as anchor points for maintaining the shape of the conductive strand as the stretchable fabric signal path expands and contracts. The outer fabric layers and inner fabric layers may be woven. The conductive strand may convey electrical signals such as audio signals, power signals, data signals, or other suitable signals.

Stretchable signal path structures for electronic devices

A planar magnetic driver including a radiating surface having a trace-free central region is described. The driver has a magnet defining an acoustic opening on a central axis. A diaphragm of the planar magnetic driver is held by mounts having a mounting profile around the central axis, and the diaphragm includes a radiating surface facing the acoustic opening. An innermost conductive trace on the diaphragm extends around a central region of the radiating surface within a magnetic flux of the magnet such that no conductive traces are on the central region. A radial distance between the innermost conductive trace and the mounting profile is less than another radial distance between the innermost conductive trace and the central axis. Accordingly, an excursion range of the diaphragm along the central axis is greater than a gap distance between the conductive trace and the magnet. Other aspects are also described and claimed.

Headphones are disclosed that include a first earcup assembly and a second earcup assembly. The headphones include a headband extending between the first and second earcup assemblies. The headband includes opposing ends attached to the first and second earcup assemblies, respectively. The first earcup assembly includes a first cushion coupled to an earcup. The first cushion includes a first portion that is acoustically open. The first cushion also includes a second portion acoustically sealed from the first portion.

Headphones with acoustically split cushions

Headphones are disclosed that include a first earcup assembly. The first earcup assembly includes a first speaker and a plurality of tunable acoustic dampeners at least partially surrounding the first speaker. The plurality of acoustic dampeners are configured to dampen standing wave resonances. The headphones include a second earcup assembly and a headband extending between the first and second earcup assemblies. The headband includes first and second opposing ends attached to the first and second earcup assemblies, respectively.

Headphones with tunable dampening features

A headphone including a circumaural or supra-aural ear cup having an ear cup housing wall which forms an interior chamber within the ear cup. A transducer is positioned within the interior chamber for producing an acoustic output to a user and an active noise control assembly positioned within the interior chamber. The active noise control assembly including a reference microphone, the reference microphone is acoustically coupled to a plurality of reference input ports spaced around the ear cup housing wall such that a sound input from each of the different spacial locations around the ear cup housing wall is received by the reference microphone and acoustically summed to provide a reference audio signal indicative of the sound input at the different spacial locations. The headphone further including a processing circuit operable to generate an anti-noise signal from the reference audio signal.

An apparatus including: a router configured to route a first audio signal to a local loudspeaker apparatus; and a switch configured to route at least one further audio signal, wherein in a first mode of operation the switch is configured to route the at least one further audio signal to at least one remote loudspeaker apparatus dependent on determining the presence of at least one remote loudspeaker apparatus, and in a second mode of operation the switch is configured to route the at least one further audio signal to the local loudspeaker apparatus.

Arranging an audio signal based on the number of loudspeakers

In accordance with an example embodiment of the invention, a method is disclosed. Near field communication is detected between at least two devices. A location of at least one of the at least two devices is determined based on the detected near field communication. An audio channel of a multi-channel audio file is assigned based on the determined location of the at least one of the at least two devices.

Method and apparatus for location based loudspeaker system configuration

A method to merge data recorded using a wireless external multi-microphone system is described. The method includes determining a communication delay between a mobile device and an accessory device. In response to activation of a camera application, an activation indication is sent to the accessory device and, in response, the accessory device starts recording audio. In response to a camera event, a camera event indication is sent to the accessory device. The camera event includes starting a video recording, pausing/resuming a video recording, ending a video recording or taking a photograph. In response to receiving the camera event indication, the accessory device creates a marker corresponding to the reception time. The method also includes receiving, at the mobile device, the audio data and the marker; and merging image data and the audio based on the marker and the communication delay. Apparatus and computer readable media are also described.
