VEHICLE SOUND CONTROL DEVICE AND METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17969170 titled 'VEHICLE SOUND CONTROL DEVICE AND METHOD THEREOF
Simplified Explanation
The patent application describes a sound control device and method for vehicles that monitors and adjusts the magnitude of a noise control signal to eliminate noise.
- The device obtains the energy per unit time of an audio signal in a specific low frequency band.
- It calculates an allowable reference value based on the difference between the energy per unit time of the audio signal and the maximum allowable input of a speaker.
- The device then monitors whether the energy per unit time of a noise control signal for noise elimination exceeds the allowable reference value.
- If the energy per unit time of the noise control signal exceeds the reference value, the device adjusts the magnitude of the noise control signal.
Potential Applications
- Automotive industry: This technology can be applied in vehicles to control and reduce noise levels, providing a more comfortable driving experience.
- Public transportation: Noise control devices can be implemented in buses, trains, and airplanes to minimize noise pollution for passengers.
- Industrial machinery: This technology can be used in heavy machinery and equipment to reduce noise emissions in industrial settings.
Problems Solved
- Noise reduction: The technology addresses the problem of excessive noise in vehicles and other environments by actively monitoring and adjusting noise control signals.
- Speaker protection: By calculating an allowable reference value based on the maximum allowable input of a speaker, the technology helps prevent damage to speakers caused by excessive noise levels.
Benefits
- Improved comfort: By effectively controlling and reducing noise levels, the technology enhances the comfort of vehicle occupants and passengers in various settings.
- Speaker longevity: The device helps protect speakers from damage by adjusting noise control signals to prevent them from exceeding the maximum allowable input.
- Customizable control: The technology allows for the adjustment of noise control signals based on specific frequency bands, providing flexibility in noise reduction strategies.
Original Abstract Submitted
A sound control device in a vehicle and control method thereof may include obtaining energy per unit time of an audio signal corresponding to a preset low frequency band, calculating an allowable reference value based on a difference between a magnitude of energy per unit time of the audio signal and a magnitude of a preset maximum allowable input of a speaker, monitoring whether a magnitude of energy per unit time of a noise control signal for eliminating noise in the vehicle exceeds the allowable reference value, and adjusting a magnitude of the noise control signal when the magnitude of energy per unit time of the noise control signal exceeds the allowable reference value.
