Microphones Signal Combination TRIZ Cases

Dynamic circumstantial data links each user to ongoing assistant actions, reducing authentication delays and misassigned commands in shared settings.

Dynamic weighting blends feedback-prone and feedback-free microphones to suppress howls while preserving far-field beamforming and interaural cues.

Beamforming plus blind source separation and distance estimation isolates the intended speaker when interference comes from the same direction.

Frequency-response comparison across microphone arrays detects aberrant signals and preserves voice control accuracy without exposing raw audio.

Real-time MIC occupation and release lets a PC use a vehicle microphone only when needed, preventing lockout and echo during device collaboration.

Local comparison of microphone frequency responses detects aberrant mics and preserves accurate voice commands without sending private audio.

Combines source positions with residual spatial information to keep 6DoF audio rendering accurate beyond the original capture area.

Blind gain adjustment aligns microphone capsule sensitivity despite wind and exposure variance, preserving array directivity and noise reduction.

Microphones placed across top, front, and back surfaces improve rear-lens narration capture and support 360-degree audio patterns.

Synchronizing multi-camera video with microphone arrays enables subject position tracking, sound source separation, and realistic audio at arbitrary listening points.

External microphones capture outside sounds and replay them through cabin speakers, preserving noise insulation while restoring critical driving cues.

Reduced phase velocity in an acoustic metamaterial boosts phase differences between close microphones, improving low-frequency directivity.

Block-based azimuth and elevation segment voting improves Ambisonics sound-source direction estimates for dual-lens capture audio.

Source-based delay estimation aligns audio from distant and local microphones while limiting buffer length for immersive spatial rendering.

Sensor-driven sound adjustment and sound guide holes help an open earphone keep ambient awareness while limiting sound leakage.

Placing the ambient microphone at an acoustic nodal point cancels speaker leakage and restores ANC and ambient control in open-wear earbuds.

Placing the ambient microphone at an acoustic nodal point helps open-wear earbuds isolate speaker sound and preserve ANC and ambient control.

Maps generator-set acoustic data into a 3D virtual sound field to localize noise sources and assess compliance before on-site changes.

Switching between interior and exterior audio representations preserves spatial consistency and smooth listener transitions in VR.

A separated interface assembly linked by a wire reduces housing interference and gives more mounting freedom during headphone assembly.

An annular rib creates dual glue slots around the headphone wire insert to improve waterproof sealing and connection stability.

Separating the interface assembly from the circuit board with a wire link eases headphone assembly and reduces interference and stress.

Separating the interface assembly from the circuit board with wires improves mounting freedom, reduces interference, and simplifies headphone assembly.

An annular rib and glue-slot interface seals the headphone wire insert, blocking water ingress while improving connection stability.
