Microphones TRIZ Cases

Virtual microphones and adaptive filters raise in-cabin speech SN ratio by extracting seat-to-seat voice more clearly without extra microphones.

Power line communication through the charging case automates wireless earphone firmware updates, cutting manual steps and update errors.

Integrated wireless charging in a headset support removes exposed contacts and enables compact multi-headset storage and charging.

A single Ethernet cable delivers power and audio data, reducing wiring complexity while supplying enough power for high-resolution playback.

An inclined electrode terminal in a profiled earphone groove improves contact alignment, raising charging and storage reliability.

A neck-hanging charger with wired bases keeps TWS earphones operating while charging, extending runtime for sports use.

White-noise seat calibration identifies each speaker-to-microphone path quickly and accurately, even with external cabin noise present.

A guide member and elastic force path replace weak magnetic or friction stops, keeping an electronic lid stable, quiet, and durable over repeated use.

A raised PCB guard ring blocks epoxy overflow from the can bonding surface, preserving bond strength and microphone package reliability.

Near-field coupling detects hearing device insertion, prevents feedback whistling, and supports safe charging without overheating.

Near-field coupling detects hearing device insertion in the charger, enabling safe charging and preventing feedback whistling.

A monitored capacitor and pulse-driven amplifier maintain low output voltage for wearable audio, improving fidelity while saving battery power.

A hybrid USB-and-battery supply lets a loudspeaker exceed USB power limits, cut adapter cost, and sustain high-output audio.

A rigid-body-mounted sensor reads deformation waveforms to detect battery contact and expansion without adding thickness.

Multiple cars are positioned as a coordinated speaker array to deliver open-air 3D surround sound with better coverage and less setup burden.

Transformer-based ground isolation and differential amplification suppress GPU power ripple before it distorts high-gain microphone signals.

Segmented piezoelectric vibrating portions let a MEMS speaker cover low and high frequencies with lower power and simpler miniaturization.

Synthetic aperture acoustic beamforming improves object localization in rain, fog, and low light by complementing camera and LiDAR sensing.

Long-range acoustic beamforming fused with RGB maps helps autonomous vehicles detect and track partially occluded objects in low light and bad weather.

Threaded director mounting adapts a small ceiling speaker to different tile thicknesses while shifting support to the ceiling grid for direct sound delivery.

An adjustable diffuser matches ceiling tile thickness and port size to improve sound dispersion while shifting speaker load to the ceiling grid.

An acoustic mapping suite lets autonomous vehicles separate, localize, and classify sirens and horns to improve perception beyond line-of-sight sensors.

Real-time resonant-frequency tracking lets piezoelectric audio drivers adapt filtering and equalization for more uniform sound pressure.

By vibrating vehicle interior materials as sound panels, this case enables stereo multichannel audio without adding bulky speakers.

A voltage-controlled filter widens microphone bias bandwidth at startup, then narrows it to preserve noise attenuation in steady state.
