Microphones TRIZ Cases

An offset-riser stand with quick-release couplers stabilizes heavy loudspeakers, cuts resonance, and enables precise 3D placement.

A tapered tightening ring lets a support frame joint rotate smoothly and hold set angles without loosening and retightening multiple bolts.

Distributed microphones and accelerometers track abrasive waterjet cutting conditions remotely, improving monitoring accuracy and nozzle life.

Multiple rotational modules and a scissor-like arm give a microphone stand wider angle and height adjustment while folding compactly for storage.

Track belts, dual fork assemblies, and cleaner power let this straddle forklift carry more harvest bins with less soil compaction and tighter turns.

A bottom reflex port and removable stand create airflow clearance, reducing port noise and diffraction while preserving flexible placement.

Noise-aware UAV positioning and microphone orientation improve target sound capture and source localization despite rotor interference.

A duct with an inner height-to-width ratio of at least 0.5 creates a quiet area around rotor blades to improve onboard recording and audio output.

A single locking shaft replaces multiple stand screws to set boom slide and two rotation axes quickly while holding a secure gap-free lock.

An extendable UAV microphone moves toward the target after flight positioning, improving sound pickup while preserving balance and flight stability.

Spring-biased locking bars replace removable pins in speaker arrays, speeding rigging while reducing wear and noise during adjustment.

Combining voice features with ear-to-microphone acoustic channel analysis helps hearing aids verify the authorized wearer with less misuse.

Sensors and motors reposition the microphone to each speaker's mouth automatically, improving comfort and keeping sound levels consistent.

A motorized display and speaker housing tracks user position to improve sound direction and viewing in a compact audiovisual device.

A spring-loaded dog and path guide enable tool-free speaker mounting with secure clamping, faster installation, and less surface damage.

Multiple vehicle audio channels are mixed into spatialized speaker output so teleoperators can localize events in real time when other sensors are blocked.

A two-stage clamping and powered rough-in approach speeds speaker installation while maintaining consistent force and protecting terminated wires.

A two-stage transmission fixing mechanism speeds ceiling device installation and removal while maintaining a secure fix.

A cam ring and spring-loaded locking members secure heavy devices in surface openings without tools, hidden studs, or surface damage.

A rotating toggle drives a fixing assembly to lock securely, then resets with a simple pushback to cut installation effort and dismantling time.

Temperature and gravity sensing let headphones distinguish temporary removal from non-use, reducing battery drain without manual power control.

A friction-inducing member keeps a panel-mount dogleg tab retracted or engaged, reducing binding during installation and removal.

A lever-actuated clamping arm secures devices to walls or ceilings from the front side, cutting installation time and handling varied substrate thicknesses.

A localized thin membrane carries speech from the mask plenum to ambient air, improving intelligibility without weakening respiratory protection.

Two repelling ring magnets create adjustable recoil mounting for in-wall speaker grilles, reducing rattling noise and part complexity.

An asymmetric horn waveguide with 3-axis aiming evens cinema sound coverage by widening short throws and focusing long throws.

A lift-up screen and rotating speaker assemblies hide large AV hardware when idle, reducing visual bulk without sacrificing viewing angle or sound quality.

Beamforming plus time and energy analysis filters reflected speech, helping autonomous devices act on the user's true direction.

A slide lock, elastic member, and release tab let speakers mount and detach quickly without tools, cutting installation time and effort.

A signal estimator switches parallel data paths by input magnitude to cut power use while preserving dynamic range in data acquisition.

Rotating loudspeaker assemblies cover or reveal an elevating screen to cut visual footprint and blend large multimedia systems into interiors.

A spring-biased dog and path guide let a speaker mount pass through an aperture, then clamp securely without screws or tools.

Elastic clamping and pressing assemblies replace screws or glue to mount electronic equipment on plates quickly, securely, and with easy release.
