Loudspeaker Screens TRIZ Cases

Segmented screens prevent dust ingress in externally ported speakers by utilizing housing channels and ledges to eliminate complex seals.

A metal bracket anchors the electronics board to improve stability and robustness while shielding against interference.

Electromagnet drives screen vibration via magnetic circuit system to resolve high energy consumption and limited driving force trade-offs.

Headrest loudspeaker deploys an air bag upon impact detection to prevent injury from hard speaker components during vehicle collisions.

Leaf springs suspend the movable diaphragm portion, improving sound pressure level power sensitivity without increasing device complexity.

Merging the acoustic driver frame with the earbud housing eliminates separate structural parts, reducing overall volume to fit smaller ears.

Merging horn and duct components resolves size constraints while extending the sound reproduction band and reducing distortion.

Segmenting the passageway isolates water from the converting portion, preserving acoustical characteristics despite independent opening placement.

Vertical membrane vibration with selective blocking maintains sound pressure and reduces distortion despite slim device thickness constraints.

Slit support portions on a diffusion plate preserve cloth body shape while allowing sound transmission through the openings.

Relocating the light-emitting member to an external mesh cover resolves internal space constraints while enabling easy disassembly.

Segmenting a single punched area into multiple through-holes reduces visual prominence while maintaining sound direction accuracy.

Segmented waterproof diaphragms deform differently to sound and vibrations, reducing vibrational noise transmission while maintaining acoustic sensitivity.
