Loudspeaker Enclosure Positioning TRIZ Cases

Opposite-phase speaker pairs built into a vehicle seat confine audio near the listener, reducing leakage and headphone discomfort.

Mobile robotic speakers use SLAM mapping and coordinated repositioning to create a concert-like acoustic sweet spot in home theaters.

Convergent optimization tunes audio sub-operations to match target frequency response while reducing manual tuning time and processing overhead.

Convergent optimization tunes audio sub-operations to match a target frequency response, cutting manual tuning time and improving small-speaker sound.

A three-emitter binaural layout shifts high and low frequencies by position to reduce inversion error, distortion, and dynamic range loss.

Selects correlated virtual speaker sets from a distribution table to improve HOA sampling flexibility and 3D audio playback quality.

Null forming cancels direct sound at the listener so a three-speaker array can create convincing height audio without dedicated elevation speakers.

Test signals and remote-microphone feedback let a casting device assign audio channels across wireless speakers for surround and multi-room sound.

HOA coefficient correlation and a preset distribution table expand virtual speaker layouts beyond regular polyhedrons for better 3D audio playback.

A three-plane transducer layout uses wall and ceiling reflections to create 3D sound with fewer speakers and lower distortion.

A casting device uses remote-control microphone measurements to assign audio channels across wireless speakers for surround and multi-room output.

Vertical segmentation of outdoor speakers eliminates out-of-phase crossover wave cancellation while maintaining wide coverage area.

Position maps guide equalized audio channel allocation across multiple speakers, resolving audio lag and quality issues during 3D rotation.

Equalization circuitry adjusts audio settings based on convertible top position to maintain consistent acoustic power distribution.

Coordinate transformation module maps audio signals from logical to physical spaces, correcting localization errors in non-rectangular rooms.

Audio channel setup system detects device position changes and updates master assignments to resolve inflexibility in static network configurations.

A stereo loudspeaker distance estimation method uses subsample delay analysis to provide real-time positioning.

A dual-orientation speaker transmits its physical position to a renderer for dynamic audio feed assignment.

Audio renderer selects distinct rendering modes per transducer subset based on position data.

Smartphone app assigns audio channels using multi-frequency chime sounds to identify wireless speakers.
