Abstract: Embodiments described herein involve configuring a playback device based on the detection of a barrier in proximity to the playback device. One embodiment may involve receiving proximity data that includes an indication of a barrier that is proximate to a playback device; detecting that the barrier is within a threshold proximity to a first speaker of the playback device based on the indication of the barrier proximate to the playback device; in response to the detecting, setting a playback configuration of the playback device; and causing the playback device to play an audio content according to the playback configuration.

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: Headphones for stereo tactile vibration, and related systems and methods are disclosed. A headphone comprises a first speaker assembly including a first audio driver and a first tactile bass vibrator. The headphone also comprises a second speaker assembly including a second audio driver and a second tactile bass vibrator. The headphone further comprises a signal processing circuit configured to generate a first tactile vibration signal and a second tactile vibration signal from an audio signal to be received by the headphone. The first tactile vibration signal differs from the second tactile vibration signal. A method of operating the headphone includes generating the first tactile vibration signal and the second tactile vibration signal, and driving vibration of the first and second tactile bass vibrators with the first and second tactile vibration signals, respectively. A stereo tactile vibrator system includes the headphone.

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: 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: Headphones include removable audio drivers electrically coupled with electrical conductors using solderless and detachable interconnections. Driver assemblies for headphones include an audio driver and a driver unit housing. An acoustical cavity is defined between the driver unit housing and the audio driver, and a port extends through the driver unit housing between the acoustical cavity and the exterior of the driver assembly. The driver unit housing is configured to be secured within an outer ear-cup housing of a headphone such that the port is open to the exterior of the headphone without communicating acoustically with a volume outside the driver unit housing and within the outer ear-cup housing. Headphones include such driver assemblies. Methods are used to form such headphones and driver assemblies.

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.
