Frequency Response Correction TRIZ Cases
- Helical Acoustic Tube for Loudspeaker Low-Frequency Sound Pressure
A loudspeaker device incorporates a spirally bent acoustic tube to enhance sound pressure across the frequency spectrum.
- Calibrating Distributed Audio Systems Using Heterogeneity Correction
A server coordinates calibration signals across heterogeneous loudspeakers to determine and correct synchronization, tuning, and volume factors.
- Miniature Speaker Module Inverted Tube Low-Frequency Response
Incorporating an inverted tube in the rear cavity forms a second driver that radiates jointly with the active driver to enhance acoustic output.
- Adaptive Bass Management Phase Modulation
A bass management system modifies audio signal phase to equalize sound pressure levels across multiple listening locations.
- Signal Processor Crosstalk Cancellation Asymmetric Gain Control
A signal processor manages speaker output using transfer functions to cancel crosstalk at the listener ear.
- Loudspeaker Enclosure with Configurable Acoustic Port
A loudspeaker enclosure uses a configurable acoustic port to manage diaphragm excursion and sound emission.
- Sound Field Control Unit Optimizing Transducer Driving Signals
A control unit generates transducer driving signals to shape acoustic sound fields across multiple zones.
- Acoustic System Humidity Compensation
A vehicle acoustic system employs a humidity sensor coupled to a control unit that adjusts exciter signals based on measured environmental moisture levels.
- Acoustic Metamaterial Device for Automated Room Geometry Estimation
Acoustic metamaterial segments decompose sound signals to calculate mirror source delays, eliminating manual room dimension input.
- Upward-Firing Driver Virtual Height Filter for Spatial Audio
Virtual height filter circuit processes upward-firing driver signals to simulate overhead sound sources via ceiling reflection.
