Microphones TRIZ Cases

A microphone array decomposes detected soundfields into sub-soundfield signals for separate processing and mixing.

A voice activated device integrates a heatsink and speaker assembly within a sealed chamber to maximize air displacement.

A flexible element allows the earmuff ear pad to move away from the head protective gear shell.

Segmented housings isolate the battery from the bone conduction cavity, preventing vibration interference and sound leakage during exercise.

A digital signal processor applies double delay-and-subtract beamforming to non-collinear microphone pairs for precise directional audio control.

A pivotable shield covers a user's mouth during speech to prevent eavesdropping on tactical audio transmissions.

A personal audio device uses a power manager to set conservation modes based on ambient noise levels.

A substrate recess with segmented upper, intermediate, and lower regions uses differential etching rates to define precise walls near the membrane.

Back-to-back speakers cancel rearward noise via phase inversion, resolving occupant confusion from omnidirectional alarm coverage.

Slotting the vibration membrane and injecting ions increases stiffness while reducing air damping to improve sensitivity.

A headphone control method simultaneously activates active noise cancellation and transparent transmission links to process external audio signals.

A microcontroller processes dual-microphone audio signals through encoding to generate data streams for noise cancellation.
