Loudspeaker Spatial/Constructional Arrangements TRIZ Cases
- Multichannel Audio Remixing for Position-Adaptive Speaker Layouts
The case remixes channel amplitudes by speaker distance, adapting the sound field to non-ideal layouts and preserving the target sweet spot.
- Speaker Waveguide for Dolby Atmos Height Channel Direction
A recessed waveguide shapes acoustic energy from an upward driver into an inclined projection path.
- HMD Audio Output Assembly with Rear Sound Conduit
Rear sound conduits route audio from internal speakers through housing apertures, enabling high-quality integrated output in compact virtual reality headsets.
- Speaker Structure With Partition Plate For Bass Reproduction
Partition plate with communication hole enables low frequency propagation between enclosures without increasing speaker width.
- Speaker Array Behind Display Screen for Audio Localization
A speaker array behind a display screen maps sound sources to specific screen locations to enhance audio realism.
- Head Tracking via ML-Processed Seat Sensors for 3D Audio
Machine learning model predicts head position from seat sensors, reducing latency and cost of 3D audio tracking.
- Audio System Dynamic Channel Routing for Flexible Speaker Placement
Processor routes multi-channel audio data to output channels based on preset speaker positions and virtual channel locations.
- Audio Object Clustering via Renderer-Aware Perceptual Difference
Renderer-aware perceptual difference guides audio object clustering, resolving the trade-off between transmission bandwidth reduction and playback accuracy.
- 3D Sound Localization for Autonomous Vehicle Passenger Notifications
Localizing 3D sound waves to specific passengers resolves ambiguity in bidirectional seating configurations.
- Hearing Device Parameter Setting via Transformation Database
A transformation database maps old device parameters to new hardware, eliminating manual acoustician adjustments and reducing fitting time.
- Smartphone Sound Field Control Using Virtual Reference Timing
A sound field control system uses a virtual reference signal to synchronize smartphone audio playback with acoustic pickup timing for precise delay processing.
- Dual Passive Radiators for Loudspeaker Walking Reduction
Opposing passive radiators cancel momentum forces to eliminate speaker walking while preserving deep bass response in a compact acoustic enclosure.
- Prime Polygon Reflectors for Non-Inverted Waveform Absorption
A prime polygon reflector uses multiple internal reflections to pass waveform energy through absorptive media.
- Zone-Based Audio Processing for 6DoF Premixed Content
Zone-based audio processing redistributes signal energy and applies distance attenuation to maintain perceptual quality during user movement in 6DoF scenes.
- Dynamic Audio Jack Color Coding for Retasking
Audio codec changes jack color via light source to resolve user confusion from fixed connector assignments.
- Multichannel Audio Directional Visualization
Visualize directional sound activity vectors from multichannel audio signals using spatial graphical representations.
- 3D Sound Adaptation via Dynamic Acoustic Radiation Steering
An electronic device dynamically calculates an acoustic radiation pattern with a principal direction aligned to the listener's location.
