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. Here are the key points:
- The device measures the energy per unit time of an audio signal in a specific low frequency range.
- It calculates an allowable reference value based on the difference between the energy of the audio signal and the maximum allowable input of the speaker.
- The device continuously monitors the energy of a noise control signal used to eliminate noise in the vehicle.
- If the energy of the noise control signal exceeds the allowable reference value, the device adjusts the magnitude of the noise control signal.
Potential applications of this technology:
- Automotive industry: This technology can be used in vehicles to control and adjust the noise levels, providing a more comfortable and enjoyable driving experience.
- Public transportation: It can be implemented in buses, trains, and airplanes to reduce noise pollution and improve passenger comfort.
- Industrial machinery: This technology can be applied to control noise levels in heavy machinery, improving worker safety and reducing noise pollution in industrial environments.
Problems solved by this technology:
- Noise control: The device helps to eliminate unwanted noise in vehicles, creating a quieter and more comfortable environment for passengers.
- Speaker protection: By calculating the allowable reference value based on the maximum allowable input of the speaker, the device prevents potential damage to the speaker caused by excessive noise levels.
Benefits of this technology:
- Improved comfort: By adjusting the noise control signal, the device ensures a more pleasant and peaceful environment for vehicle occupants.
- Speaker longevity: The device protects the speaker from damage by monitoring and adjusting the noise control signal.
- Noise reduction: This technology helps to reduce noise pollution in various settings, enhancing the overall quality of the environment.
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.
