Non-Occlusive Ear Tips TRIZ Cases

See how shape memory materials enable a wearable audio device to adapt to different ear anatomi

A strip-shaped sound outlet and compact acoustic cavity raise sound pressure and reduce interference in comfort-focused ear-clip earphones.

Detachable exterior members let one earwear core shift appearance and sound output for different settings without adding core structural complexity.

A detachable exterior lets one earwear design change appearance and sound port position to suit different occasions and ear sizes.

Dual loudspeakers with angled magnetic axes and outlet holes improve sound pressure by frequency band while keeping the ear canal open.

Separate low- and high-frequency loudspeakers improve open-ear sound pressure while keeping the ear canal unblocked for ambient hearing.

Antiphase acoustic output through separate housing openings cancels leaked sound from open-ear audio while preserving ear comfort.

A concha-seated acoustic module and behind-ear battery housing improve headphone stability and comfort without outer-ear clamping.

A layered ear tip uses fixing portions, material homogeneity, and an outlet to preserve shielding while discharging foreign substances.

A soft actuator adjusts ear-canal ventilation electrically, avoiding motion sound from magnetic vent switching.

An acoustic module fits the cavum conchae while a behind-ear battery housing supports comfort, stability, and discreet wear.

Segmenting acoustic paths isolates private audio from ambient noise, resolving the contradiction between sound insulation and environmental awareness.

A passive acoustic metamaterial device matches complex ear canal impedance using stacked shunt compliance chambers and annular inductive channels.

Groove on earphone housing forms hollow tube with flexible ear tip to relieve occlusion effect without compromising noise isolation.

Offset sound port and asymmetric housing improve acoustic performance while maintaining structural integrity of non-occluding earbuds.

A hearing aid insert member features a protruding engagement member for tool removal.

Rotating the adjusting module alters acoustic vent aperture size, reducing occlusion effect and microphonics while enabling customizable noise isolation.

Segmented ear canal protrusion with local quality differentiation secures attachment and prevents occlusion effects without high frequency filtering.

Segmented shell modules allow one main unit to switch between in-ear, half-in-ear, and open-ear forms, reducing production costs and development cycles.

Angled nozzle aligns feedback microphone to ear canal, improving bass response and noise cancellation.

A solenoid actuator moves a core to open or close an earpiece vent based on listening environment data.

Segmenting the earphone into hook, connector, and holding components maintains ambient sound hearing while securing attachment stability.

An inverted flange earbud creates a debris reservoir to collect wax and protect the acoustic path.

Segmented earbud flutes route ambient noise around the central speaker, resolving safety risks from sound isolation without compromising audio quality.

Swept indents on compliant eartip flanges conform to irregular ear canals, reducing pressure points and improving user comfort.

A sound collecting device with an attachment portion and holding portion maintains acoustic transparency within the external ear canal.

Segmenting the earphone and extending a cord along the auricle improves retention stability without increasing visible bulk or causing discomfort.

Multi-durometer materials separate soft sealing surfaces from rigid structural supports to resolve comfort versus stability trade-offs.

Matched resonance frequencies in separate acoustic cavities reduce sound spillage while maintaining environmental awareness.

Midmold segmentation isolates speaker front volumes to tune frequency response independently, resolving acoustic interference without an airtight seal.
