The wiring system comprises a first wiring assembly comprising two audio jacks configured to connect to the audio jacks of the two speaker assemblies and two wires connected to the two audio jacks at first ends of the two wires. Headphone assemblies may comprise two speaker assemblies and a headband configured for removable attachment to the speaker assemblies. Each speaker assembly may comprise an attachment structure configured for attachment to another device or structure, wherein the attachment structure of each speaker assembly of the two speaker assemblies comprises a frustoconical surface and two first attachment features comprising elongated features on the frustoconical surface.

Abstract: Modular audio headphone devices comprise a first user-wearable accessory and at least one headphone configured for releasable attachment to the first user-wearable accessory. The at least one headphone comprises a speaker. A speaker housing is coupled to the speaker and may be configured to form an acoustic cavity proximate at least a portion of the speaker. The at least one headphone may be configured to provide a first emitted sound pressure level (SPL) profile over a range of frequencies when the at least one headphone is attached to the first user-wearable accessory, and to provide a different second emitted SPL profile over the range of frequencies when the at least one headphone is not attached to the first user-wearable accessory.

Abstract: Earbud headphones may be configured to be secured to a user's outer ear. The earbud headphones may comprise a speaker assembly configured to convert an audio signal into a sound wave audible to the human ear. A main body portion may support the speaker assembly. An extension may extend from the main body portion away from the speaker assembly to define a gap between the extension and the speaker assembly. The gap may be sized and positioned to receive a portion of a user's outer ear within the gap such that the portion of the user's outer ear is disposed between the extension and the speaker assembly and retains the earbud headphone in the ear of the user when the earbud headphone is worn by the user.

Abstract: A speaker comprises a support structure having a circumferentially extending rim, a vibration member configured to be displaced relative to the support structure during operation of the speaker, and a suspension member suspending the vibration member relative to the support structure. The suspension member includes a radially outer portion attached to the rim of the support structure, a radially inner platform portion attached to the vibration member, and a plurality of beams. Each beam of the plurality of beams may extend from the radially outer portion to the radially inner platform portion. The plurality of beams is configured such that a resonant frequency of the vibration member attached to the radially inner platform portion of the suspension member scales linearly with a beam width of the beams of the plurality of beams.

Abstract: A wiring harness for clothing, and garments so equipped. The wiring harness is of asymmetrical configuration, and may extend through channels positioned substantially along reinforced portions of the garment. The wiring harness includes a T-junction from which extend a male media connector and two media cables, a first media cable extending along seams of one side of the garment, and a second media cable extending along a neck portion of the garment from the T-junction at one side to another side, both media cables terminating in male media connectors. The male media connector of the T-junction and the male media connector of the second media cable connect to female media connectors of earphone cables, while the male media connector of the first media cable connects to a female media connector of a portable media device, which may be disposed within a pocket of the garment.

Abstract: An apparatus related to a magnetic circuit design is disclosed. The apparatus includes a magnetic assembly and an electrically-conductive mobile member. The magnetic assembly includes an inner magnet, an outer magnet, an inner cap, an outer cap and a washer. The magnetic assembly is configured to produce a magnetic field having a zone of operation between the inner cap and the outer cap. The zone of operation has substantially uniform magnetic field strength. The zone of operation has magnetic field directions substantially perpendicular to an ideal motion direction. The electrically-conductive mobile member is disposed in the zone of operation of the magnetic field and electrically coupled to a diaphragm of a driver. The electrically-conductive mobile member is configured to move within the zone of operation of the magnetic field in response to the magnetic field when an alternating current is passed through the electrically-conductive mobile member.

Abstract: The disclosure includes a system and method for sonically customizing an audio reproduction device. The system includes a processor and a memory storing instructions that when executed cause the system to: determine an application environment associated with an audio reproduction device associated with a user; determine one or more sound profiles based on the application environment; provide the one or more sound profiles to the user; receive a selection of a first sound profile from the one or more sound profiles; and generate tuning data based on the first sound profile, the tuning data configured to sonically customize the audio reproduction device.

Abstract: Methods of transmitting and receiving audio using in-ear headphones may comprise receiving sound from an ear canal at an in-ear headphone comprising a flexible insert, the flexible insert forming a seal between walls defining the ear canal and the flexible insert. The sound may be converted to an audio signal using the in-ear headphone in a receiving mode. The audio signal may be transmitted from the in-ear headphone to an audio signal transmitting and receiving device. The in-ear headphone may receive an audio signal from the audio signal transmitting and receiving device. The audio signal may be converted to sound and the sound may be transmitted into the ear canal using the in-ear headphone in a transmitting mode.

Abstract: A system for interacting with an audio reproduction device and a user using the audio reproduction device is disclosed. The system includes: an image capture module capturing an image depicting an audio reproduction device used by a user; an image recognition module performing image recognition to extract recognition data from the image, the recognition data including data describing the audio reproduction device and one or more deteriorating factors that deteriorate a sound quality in the audio reproduction device; a filter module estimating a sound degradation in the audio reproduction device that is caused by the one or more deteriorating factors, the filter module applying a digital filter to compensate the sound degradation in the audio reproduction device; an aggregation module aggregating data associated with the user, the aggregated data including the recognition data; and a recommendation module providing one or more recommended items to the user.
