VEHICLE PROXIMITY NOTIFICATION DEVICE, VEHICLE PROXIMITY NOTIFICATION METHOD, AND MOBILE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18375277 titled 'VEHICLE PROXIMITY NOTIFICATION DEVICE, VEHICLE PROXIMITY NOTIFICATION METHOD, AND MOBILE DEVICE

Simplified Explanation

The vehicle proximity device described in the abstract is a system that processes audio signals to simulate the sound of a second source in order to adjust the sound pressure levels and reduce differences between the original audio signals and the simulated ones.

• The obtainer extracts first and second frequency bands from a sound source signal to obtain two audio signals.
• The simulated signal processor generates a simulated signal based on a second sound source signal.
• The third and fourth filters extract the first and second frequency bands from the simulated signal.
• The sound pressure adjuster adjusts the simulated signal to reduce differences between the original audio signals and the simulated ones.
• The outputter sends the adjusted audio signal to the loudspeaker.

Potential Applications

This technology could be used in vehicles to enhance the audio experience for passengers by simulating additional sound sources and adjusting sound pressure levels accordingly.

Problems Solved

This technology helps reduce differences in audio signals, providing a more balanced and immersive sound experience for vehicle occupants.

Benefits

The benefits of this technology include improved audio quality, enhanced sound immersion, and a more enjoyable listening experience for passengers in vehicles.

Potential Commercial Applications

One potential commercial application of this technology could be in the automotive industry, where it could be integrated into vehicle audio systems to provide a more advanced and customized audio experience for customers.

Possible Prior Art

One possible prior art for this technology could be existing audio processing systems used in vehicles to adjust sound levels and enhance audio quality for passengers.

Unanswered Questions

The article does not discuss the potential limitations of this technology when used in noisy environments where multiple sound sources may interfere with the audio processing capabilities of the device.

Original Abstract Submitted

A vehicle proximity device includes: an obtainer that obtains a first audio signal obtained by extracting a first frequency band of a first sound source signal and a second audio signal obtained by extracting a second frequency band thereof; a simulated signal processor that generates a simulated signal based on a second sound source signal; a third filter that generates a third audio signal by extracting the first frequency band of the simulated signal; a fourth filter that generates a fourth audio signal by extracting the second frequency band of the simulated signal; a sound pressure adjuster that generates an output audio signal by adjusting the simulated signal to reduce a first difference between the first audio signal and the third audio signal and a second difference between the second audio signal and the fourth audio signal; and an outputter that outputs the output audio signal to the loudspeaker.
