Microphones TRIZ Cases
- Speaker Framing via Face-Guided Sound Source Localization
A videoconferencing system correlates microphone array pan angle data with image-based face detection bins to stabilize speaker framing.
- Wireless Earpiece Local Audio Cache for Power Reduction
Local audio cache stores music files in wireless earpieces, reducing power consumption from continuous streaming.
- Wireless Illuminative Speaker System Remote Control Integration
A wireless illuminative speaker system integrates a remote control module into the transmitter body to share processing resources.
- Wiring Structure for Digital Signal Electroacoustic Transducer
Stranded input lines connect voice coils to a diaphragm, preventing extraneous noise invasion that degrades sound quality.
- Wireless Earpiece Software Interface for Music and Activity Control
A mobile application provides a unified interface to control music playback and monitor activity data from wireless earpieces.
- Denoising Microphone Sensor Module Interference
A denoising apparatus subtracts interference noise signals from voice data to maintain compact module size.
- Integrated Fire Detector Sounder Reduces Wiring Connections
A sounder device merges speaker functionality into the detector housing to eliminate separate wiring infrastructure.
- Energy Directing Surface Non-Zero Deflection Angle
Energy directing surface uses non-zero deflection angles to focus projected energy rays toward the surface via waveguide arrays.
- Articulating Headphones with Biased Hinge Mechanism
Disc springs in a forked hinge bias articulating earpieces to fixed positions, eliminating swinging and providing audible feedback for secure folding.
- Display Panel Sounding via Transmission Channels
Sounding units transmit audio through pixel group channels to output sound, eliminating vibration damage risks.
- Headset Microphone Boom Position Sensing and Correction
A headset sensor detects microphone boom angle and proximity to maintain optimal audio capture.
- Stochastic Channel Feedback for MU-MIMO Throughput
User equipment predicts channel estimation errors to enable base station stochastic precoding, reducing inter-user interference in time-varying channels.
