APPARATUS AND METHOD FOR GENERATING A FIRST CONTROL SIGNAL AND A SECOND CONTROL SIGNAL BY USING A LINEARIZATION AND/OR A BANDWIDTH EXTENSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240040303 titled 'APPARATUS AND METHOD FOR GENERATING A FIRST CONTROL SIGNAL AND A SECOND CONTROL SIGNAL BY USING A LINEARIZATION AND/OR A BANDWIDTH EXTENSION

Simplified Explanation

The patent application describes an apparatus for generating control signals for two transducers based on audio signals. The apparatus includes an input interface for receiving audio signals for two audio channels, a signal combiner for determining a combination signal that represents the difference between the two audio signals, a signal manipulator for manipulating the combination signal to obtain the second control signal, and an output interface for outputting or storing the first control signal based on the first audio signal or the second control signal.

  • The input interface receives audio signals for two audio channels.
  • The signal combiner determines a combination signal that represents the difference between the two audio signals.
  • The signal manipulator manipulates the combination signal to obtain the second control signal.
  • The output interface outputs or stores the first control signal based on the first audio signal or the second control signal.

Potential applications of this technology:

  • Audio systems: The apparatus can be used in audio systems to generate control signals for transducers, allowing for improved sound quality and performance.
  • Virtual reality: The technology can be applied in virtual reality systems to enhance the audio experience by providing accurate control signals for transducers.
  • Automotive industry: The apparatus can be integrated into car audio systems to optimize the performance of transducers and provide a better audio experience for passengers.

Problems solved by this technology:

  • Non-linear transducer characteristics: The signal manipulator can counteract the non-linear characteristics of transducers by delaying, amplifying, or attenuating the combination signal in a frequency-selective manner. This helps to improve the accuracy and fidelity of the audio output.

Benefits of this technology:

  • Improved sound quality: By generating control signals based on the combination of audio signals, the apparatus can enhance the sound quality and provide a more immersive audio experience.
  • Compatibility: The apparatus can be integrated into existing audio systems and devices, making it compatible with a wide range of applications.
  • Customization: The signal manipulator allows for the manipulation of the combination signal, providing flexibility and customization options for different transducer characteristics and audio requirements.


Original Abstract Submitted

an apparatus for generating a first control signal for a first transducer and a second control signal for a second transducer, including: an input interface providing a first audio signal for a first audio channel and a second audio signal for a second audio channel; a signal combiner for determining from the first audio signal and the second audio signal a combination signal including an approximate difference of the first audio signal and the second audio signal; a signal manipulator for manipulating the combination signal to obtain the second control signal; and an output interface for outputting or storing the first control signal based on the first audio signal, or the second control signal, wherein the signal manipulator is configured to delay the combination signal or to amplify or attenuate the combination signal in a frequency-selective manner to counteract a non-linear transducer characteristic over the frequency of the second transducer.
