US 11,540,039 B2 · Eartips for coupling via wireform attachment mechanisms

Abstract

Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end. The eartip body can include an inner eartip body having a sidewall extending between the interfacing end and the attachment end, the sidewall defining a channel and having a first thickness near the attachment end and a second thickness different from the first thickness at the interfacing end. The eartip can also include an attachment structure coupled to the inner eartip body at the attachment end, the attachment structure having an inner surface and an outer surface. The attachment structure can include an upper region interfacing with the sidewall and defining discrete through-holes, a lower region below the upper region where the inner surface defines a plurality of recesses positioned around the lower region, and a mesh extending across the channel and into the upper region.

Dependent claims

A detachable ear tip for an in-ear headphone, the detachable ear tip comprising:

a compliant ear tip body having an attachment end and an ear interfacing end opposite from the attachment end, the compliant ear tip body comprising:
an inner ear tip body having an inner ear tip body sidewall extending between the ear interfacing end and the attachment end and defining a sound channel through the compliant ear tip body;
and
an outer ear tip body sized and shaped to be inserted into a human ear canal, the outer ear tip body extending from the ear interfacing end toward the attachment end of the compliant ear tip body;
and
a rigid attachment structure having a frame sidewall that defines an oval-shaped channel through the rigid attachment structure and aligned with the sound channel, the rigid attachment structure including an upper portion coupled to the inner ear tip body sidewall and a lower portion below the upper portion where an inner surface of frame sidewall defines first and second recesses protruding into the rigid attachment structure and positioned at opposite ends of the oval-shaped channel within the lower portion;
and
a mesh coupled to the rigid attachment structure and extending across the oval-shaped channel.

A detachable ear tip for an in-ear headphone having:

(i) an audio driver positioned within a housing and aligned to emit sound through an acoustic opening, (ii) a nozzle centered within the acoustic opening and having a nozzle sidewall with first and second openings formed through opposite sides of the sidewall, and (iii) an attachment feature positioned within nozzle and having first and second spring ends protruding through the first and second openings, respectively, in the nozzle sidewall towards an inner perimeter of the acoustic opening, the detachable ear tip comprising:
a compliant ear tip body having an attachment end and an ear interfacing end opposite from the attachment end, the compliant ear tip body comprising:
an inner ear tip body having an inner ear tip body sidewall extending between the ear interfacing end and the attachment end, the inner ear tip body sidewall defining a sound channel through the compliant ear tip body;
and
an outer ear tip body sized and shaped to be inserted into an ear canal, the outer ear tip body extending from the ear interfacing end toward the attachment end of the compliant ear tip body;
and
the rigid attachment structure having a frame sidewall that defines a first oval-shaped opening at a top surface of the rigid attachment structure and a second oval-shaped opening, larger than the first oval shaped opening, at a bottom surface of the rigid attachment structure, wherein:
the frame sidewall defines a frame channel through the rigid attachment structure extending from the first oval-shaped opening to the second oval-shaped opening and axially aligned with the sound channel;
the rigid attachment structure includes an upper portion adjacent the first oval-shaped opening and coupled to the inner ear tip body sidewall, and a lower portion adjacent the second oval-shaped opening, wherein a bottom surface of the lower portion is sized and shaped to fit within the acoustic opening when the detachable ear tip is attached to the in-ear headphone;
and
an inner surface of the frame sidewall defines first and second recesses protruding into the rigid attachment structure and positioned 180 degrees apart from each other within the lower portion, wherein, when the ear tip is attached to the in-ear headphone, the first and second recesses align with and extend over the first and second spring ends;
and
a mesh coupled to the upper portion of the rigid attachment structure and extending across the frame channel.
