HOW klaraT® WORKS
The unique technology and software algorithm speaker compensation of subVo, is klaraT®.
The sensor, a proprietary screen-printed carbon ink sensor, changes in resistance when it is bent. The sensor technology can be added to speaker diaphragms or screen-printed directly onto the diaphragm of the speaker to attain perfect synergistic motion. The sensor can see precise diaphragm movements throughout the entire audible spectrum.
The software consists of proprietary feedback control loop algorithms as well as speaker protection algorithms so your speakers can operate at their limits without introducing distortion or damage. The software can be ported to many audio subsystems such as smart codecs and smart amps with integrated DSPs.
subVo is using their klaraT® technology to research new speaker construction techniques and diaphragm materials which enable better acoustic performance and increased longevity. Traditionally these materials had been dismissed due to their stiffness or mass, but with the klaraT® Technology these effects are overcome.
We at subVo welcome new partners in the audio space to utilize our klaraT® Technology and research what other performance increases and cost savings might be realized.
klaraT® and SMARTPHONES
The leading cause of poor speech intelligibility on mobile devices is harmonic distortion. Harmonic distortion is caused by a non-linear transfer function of the loudspeaker. The harmonic distortion becomes worse when the loudspeaker operates too close to the maximum limits. This creates a trade-off between maximum loudness and distortion. Now you can have the best of both worlds with subVo klaraT® technology. With klaraT®, the loudspeaker transfer function is linearized and protected from maximum excursion which causes distortion.
The industry standard diaphragm measuring device is a laser vibrometer. Laser vibrometers are very accurate and would make really good diaphragm tracking sensors but have two flaws. 1. They are very expensive costing thousands of dollars and therefore would be impractical to ship one with every speaker. 2. There is lag between the diaphragm’s actual position in real-time and the signal output of the laser vibrometer.
The klaraT® Sensor tracks as accurately as the laser vibrometer, but produces almost no lag, and it can practically be shipped with every speaker since it only costs dollars to add to the system.
BENEFITS OF USING klaraT®
• Reduced distortion caused by spring forces of the suspension/box pressure and mass of diaphragm.
• Frequency responses are flattened. And frequencies below the resonant frequency of the system are amplified.
• Near perfect impulse response without delay
• Results Identical to laser measuring, with no lag time.
• Provide smaller enclosures by reducing airspace needed.
• Stronger/longer lasting speaker materials which previously would've produced acoustic problems can now be used.
• Cost savings of self-calibration, instead of factory calibration.
• Speaker protection to safe limits without guessing.
