A design system generates a design for an in-ear device customized for a user. The in-ear device produces audio content for the user. The design system captures anthropometric data of the user. Using machine learning techniques, the design system determines features of an ear of the user from the anthropometric and generates a three dimensional (3D) geometry of the user's ear. A design for the in-ear device is generated based on the 3D geometry of the user's ear and includes a shell configured to fit in at least a portion of an ear canal of the user.

An acoustic device with an open audio device structure that is configured to be carried on the head or upper torso of a user, a housing carried by the open audio device structure, the housing having opposed first and second ends, a flat diaphragm in the housing and comprising a front face and a rear face, the diaphragm configured to radiate front acoustic radiation from its front face and rear acoustic radiation from its rear face, wherein the front and rear acoustic radiations are out of phase, structure that supports the diaphragm such that the diaphragm can move relative to the housing, a primary magnet adjacent to the rear face of the diaphragm, a magnetic circuit that defines a path for magnetic flux of the primary magnet, a voice coil that is exposed to the magnetic flux and is configured to move the diaphragm up and down along a radiation axis that is normal to the front face of the diaphragm, and first and second sound-emitting outlets in the housing, wherein the first sound-emitting outlet is in or proximate the first end of the housing and is acoustically coupled to the front face of the diaphragm so as to emit front acoustic radiation into an acoustic space, and wherein the second sound-emitting outlet is in or proximate the second end of the housing and is acoustically coupled to the rear face of the diaphragm so as to emit rear acoustic radiation into the same acoustic space.

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.

An ear wearable device includes a housing, a speaker, a structure, nonconductive supporting member, and an Integrated Circuit (IC). The housing includes a nonconductive cover. The speaker is positioned in the housing. The structure is positioned in the housing and includes a nonconductive supporting member facing the nonconductive cover and positioned in the housing, and a first conductive pattern positioned on the nonconductive supporting member. The nonconductive bonding member is positioned between the structure and the nonconductive cover. The touch sensor IC is positioned in the housing and electrically connected with the first conductive pattern.

In accordance with the present invention, an ear tip for increasing mid-range frequency perception of an earpiece is provided. The ear tip includes a hollow main body having a first end defining a first opening and a second end defining a second opening for coupling to a coupling portion of a housing of the earpiece, and a peripheral portion integrally coupled to an outer surface of the first opening and shaped to conform to a surface of an ear canal. The peripheral portion has an outer edge with a plurality of wedge-shaped apertures formed integrally and spaced around the outer edge. The second opening and/or the coupling portion of the housing are adapted to be acoustically coupled with each other.
