A portable eyewear electronic device that includes a speaker module and methods of assembly of the device are presented. The electronic eyewear device includes a speaker module that emits acoustic radiation that is channeled through a carrier contained within a temple to one or more acoustic ports near a user's ear.

Dual port constrained acoustic volume

An electronic eyewear device includes a display and a speaker system adapted to present augment reality objects and associated sounds in a scene being viewed by the user. A processor receives one or more audio tracks respectively associated with one or more augmented reality objects, encodes the audio tracks into an aggregated audio track including the audio tracks, a header for each audio track that uniquely identifies each respective audio track, and an aggregate header that identifies the number of tracks in the aggregated audio track. The processor transfers the aggregated audio track to an audio processor that uses the header for each audio track and the aggregate header to separate the audio tracks from the aggregated audio track. The audio processor processes the audio tracks independently in parallel and provides the audio tracks to the speaker system for presentation with the augmented reality objects.

Low latency, low power multi-channel audio processing

Some headphone systems include two ear cups, a headband assembly, an interface system and a control system. Each ear cup may include an ear cup enclosure, an ear pad assembly, a speaker system and a hinge assembly. The hinge assembly may be disposed within the ear cup enclosure such that it is not visible from outside the ear cup. The headband assembly may connect with each of the ear cups via the hinge assembly. The interface system may include at least one interface and a plurality of input source buttons disposed on at least one of the ear cups. Each of the input source buttons may be configured for selecting a source of audio data received via the at least one interface. The control system may be configured for controlling the speaker system to reproduce audio data received via the interface and selected by one of the input source buttons.

Headphones and headphone systems

Example systems, devices, media, and methods are described for efficiently processing an audio track of a virtual object with a head-related transfer function (HRTF). Audio tracks are processed by determining a current position (direction and optionally distance) of the virtual object with respect to the head of a user, identifying a current audio zone from predefined audio zones responsive to the determined current position where each of the audio zones has a corresponding left predefined filter and a corresponding right predefined filter, applying the left and the right predefined filters corresponding to the current audio zone to the audio track to produce a left audio signal and a right audio signal, and presenting the left audio signal with a first speaker and the right audio signal with a second speaker.

Head-related transfer function

A cooling device generating unidirectional air flow to cool an electrical component. The cooling device is an equivalent of an electrical acoustic diode to make air flow only one direction. A speaker generates air flow in a first passageway to a cavity, and then expels air out from the cavity through a second passageway. An electrical component is cooled by the air flow, and may be positioned adjacent the passageways, or positioned in the cavity. In one example, eyewear having an electrical component positioned in a temple is cooled by the cooling device.

Acoustic air pump

There is disclosed active acoustic filter systems and methods. A processor is disposed within a housing configured to interface with a user's ear. A memory stores data defining one or more locations and a respective set of location-based processing parameters associated with each of the one or more locations. A personal computing device external to the housing is coupled to the processor via a first wireless communications link. The personal computing device determines a current location of the active acoustic filter system. The processor generates digitized processed sound by processing digitized ambient sound in accordance with a set of location-based processing parameters retrieved from the memory, the retrieved set of location-based processing parameters associated with the current location of the active acoustic filter system as determined by the personal computing device.

Each ear cup () includes an ear cup enclosure (), an ear pad assembly (), a speaker system () and a hinge assembly (). The hinge assembly () is disposed within the ear cup enclosure () such that it is not visible from outside the ear cup (). The headband () assembly connects with each of the ear cups () via the hinge assembly (). The interface system () includes at least one interface and a plurality of input source buttons () disposed on at least one of the ear cups (). Each of the input source buttons () is configured for selecting a source of audio data received via the at least one interface. The control system () is configured for controlling the speaker system () to reproduce audio data received via the interface and selected by one of the input source buttons ().

Active acoustic filter systems and methods are disclosed. An active acoustic filter system includes a memory storing one or more stored sound profiles and a respective set of processing parameters associated with each of the one or more stored sound profiles. A processor coupled to the memory generates processed sound by processing ambient sound in accordance with a set of processing parameters retrieved from the memory based on results from comparing an ambient sound profile to at least one of the one or more stored sound profiles.

Active acoustic filter with automatic selection of filter parameters based on ambient sound

Ambient sound is converted into digital signals. A processor performs active noise cancellation and/or a transformation operation that is distinct from the active noise cancellation on the digital signals. The active noise cancellation and the transformation operation transform the digital signals into modified digital signals. The modified digital signals are converted into modified analog signals. The modified analog signals are outputted as audio waves. An interior microphone is configured to output an output signal to the processor in response to receiving the modified analog signals. In response to receiving the output signal from the interior microphone, the processor is configured to determine whether the modified digital signals produce desired audio waves.

Real-time audio processing of ambient sound

A combined ambient sound and secondary audio system comprises at least one microphone for receiving ambient sound, at least one receiver for receiving secondary audio from a secondary audio source not audible in the ambient sound. The system further includes a memory storing one or more sets processing parameters comprising instructions for processing the ambient sound and the secondary audio and a processor coupled to the memory, the microphone, and the receiver configured to generate combined ambient and secondary sound by combining the ambient sound and the secondary audio as directed by a selected set of processing parameters retrieved from the memory.
