Grooves, a screen wall, and a spaced screen board block and drain oblique water jets and other foreign matter while preserving sound quality.

Opposed mold pins with different end-face sizes form stepped grille holes that resist pin deformation and reduce burrs during resin molding.

An asymmetrical acoustic lens and phase plug guide sound through a smaller aperture to reduce response nulls and stabilize in-car tonal balance.

Annular sound-guiding members and foam isolation keep 3D headrest fabric from flapping while reducing speaker interference and improving stereo sound.

A movable sealing member blocks the housing vent under high water pressure while preserving daily breathability and air pressure balance.

A meshed open acoustic port relieves ear-canal pressure while preserving bass response and comfort in wireless earphones.

Laser-drilled micro-openings in layered fabric hide speakers, vents, and lights while still passing sound, air, and illumination.

Interleaved multi-layer crossbeams protect pedestrian warning sounder internals while preserving airflow and outward sound diffusion.

A movable sealing switch blocks the housing vent under high water pressure, protecting the breathable film while preserving daily pressure balancing.

Distance data from an adjacent optical module calibrates object temperature while the stacked sensor layout limits optical cross-talk in wearables.

A resonant sealing member covers the bumper through hole, preserving surface appearance while maintaining ultrasonic transmission and echo reception.

A vibrating plate and enclosure boost low-band sound pressure and stereo effects in vehicles without adding bulky coil speakers.

A resonant sealing member covers the bumper through hole, preserving surface appearance while maintaining strong ultrasonic transmission and echo reception.

Integrated grille openings in a decorative sheet let sound and air pass through, removing separate mounts and preserving a clean vehicle interior surface.

A sound-permeable carrier layer lets headrest speakers play through foam while preserving a safe, comfortable bearing surface.

Using sapphire glass over acoustic installation holes cuts 5G antenna interference and removes the 1.5 mm clearance penalty in compact terminals.

A border antenna with sound output holes frees internal terminal space while preserving wireless transmission and audio assembly layout.

Grille-mounted Helmholtz and tube resonators suppress 1-3 kHz standing waves caused by ear pad leakage, improving headphone noise cancellation.

A molded grille-enclosure, snap features, and adhesives cut assembly complexity while improving water sealing for exterior vehicle loudspeakers.

Laser-drilled micro-openings in layered fabric and foam hide speakers, vents, and lights while still passing sound, air, and light.

Interleaved multi-layer grille crossbeams protect pedestrian warning sounder parts from dust while preserving airflow and sound diffusion.

A border antenna shares sound output holes with the audio path, freeing middle-frame space for antenna placement while preserving sound output.

Movable louvers and waveguide elements redirect speaker output to improve in-vehicle and external sound coverage while saving space and weight.

A recessed acoustic port mesh and optical in-ear sensing improve sound delivery, hands-free use, and battery protection in wireless earphones.
