Abstract: A design system generates a design for an eyewear frame customized for a user. The eyewear frame provides audio content to the user. The design system captures anthropometric data of the user. Using machine learning techniques, the design system determines features of the user from the anthropometric data and generates a three dimensional (3D) geometry of the portion of the user's head. A design for the customized eyewear frame is generated based on the 3D geometry of the portion of the user's head. The design of the customized eyewear frame includes design parameters that describe a shape of a coupling element that ensures the eyewear frame is customized to the user's head.

Abstract: An in-ear device is implemented as part of an audio system to present a user with improved audio content within an artificial reality system. The in-ear device is a fully integrated device with an internal microphone, an external microphone, and a transducer in which portions of the transducer form portions of the body of the device. This integration of transducer into the body of the in-ear device reduces the size of the in-ear device and allows for placement deeper within the ear canal of the user. The transducer generates audio content based on instructions received from an audio system that may be located on a device that is external to the in-ear device. The external microphone provides hear-through functionality, while the internal microphone provides feedback information to the audio system.

Abstract: An electronic device may include one or more terminals configured to provide a voltage signal to an actuator. The electronic device may detect a current associated with the voltage signal provided by the terminal to the actuator. The electronic device may determine an impedance across associated with the actuator based on the voltage signal and the electrical current. The electronic device may compare the impedance to a threshold impedance to determine whether there is sufficient skin contact with the actuator. The electronic device may provide audio via cartilage conduction if there is sufficient contact based on comparing the impedance to the threshold impedance, or may output a notification to the user to adjust placement of the electronic device to improve contact.

Abstract: Embodiments relate to an audio system configured to provide enhancement of low audio frequencies. The audio system includes a tissue transducer and a speaker coupled to the tissue transducer. The tissue transducer is configured to be coupled to a tissue of a user (e.g., pinna of a user's ear). The speaker includes a diaphragm having a first surface and a second surface that is opposite the first surface. The first surface is configured to generate a first set of airborne acoustic pressure waves, and the second surface is configured to generate a backpressure. The tissue transducer is driven by the backpressure to vibrate the tissue to form a second set of acoustic pressure waves. The first set of airborne acoustic pressure waves and the second set of acoustic pressure waves together form audio content that is presented to the user.

Abstract: A cartilage conduction system may include (1) a transducer that generates mechanical energy and (2) a functionally graded material (FGM) interface dimensioned to be coupled between the transducer and cartilage located on an outer ear of a user, wherein the FGM interface (1) exhibits a gradation of at least one characteristic from one side of the FGM interface to another side of the FGM interface and (2) facilitates transferring the mechanical energy across the gradation of the characteristic from the transducer to the cartilage. Various other systems and methods are also disclosed.
