Remote Warning Sound Capturing Device with Directional Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In noisy environments, existing sound capturing devices struggle to effectively detect and alert users to warning sounds from remote sources, such as approaching vehicles, due to their inability to focus on sounds from all directions and automatically recognize the source of warning sounds, leading to delayed responses and increased accident risks.
Innovation Solution
A capturing device that uses an audio pick-up device, processor, and speaker to receive and process remote sound signals, employing a deep learning algorithm to identify and amplify sound features matching warning voiceprint data while suppressing non-warning sounds, and outputting a warning sound component to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sound collector is used to focus on sounds from a specific direction, then the audio pick-up device can receive sounds from a specific direction, but it cannot effectively receive warning sounds emitted from all directions
Solution Approach 1:
The patent divides the sound detection task into multiple segments by using multiple microphones arranged in an array. Each microphone captures sound from its specific position, and the combined signals provide both directional information and omnidirectional coverage. This segmentation allows the system to achieve precise directional detection while maintaining the ability to detect sounds from all directions.
2Quantity of substance
If the audio pick-up device receives multiple sounds, then it can capture various sound sources, but it cannot automatically recognize the source making the warning sound component
Solution Approach 1:
The system uses feedback mechanisms by continuously comparing the captured sound signals against a database of warning sound patterns. The processor analyzes the received sounds, compares them with known warning sound characteristics, and provides automatic recognition and identification of warning sound sources. This feedback loop enables the system to automatically distinguish warning sounds from other sounds without manual intervention.
3Productivity
If the prior art processing method is used, then it can process received sounds, but it may not be able to provide the user with the related warning sound component in time before the related accident occurs
Solution Approach 1:
The system performs preliminary actions by pre-loading and storing various warning sound patterns and characteristics in the processor before actual sound detection occurs. When a sound is captured, the processor immediately compares it against the pre-stored patterns, enabling rapid identification and immediate warning to the user. This preliminary preparation significantly reduces processing time and ensures timely warning provision.

AI summary
The present disclosure relates a capturing device of remote warning sound component which utilizes an audio pick-up device receives a remote sound signal in a remote range, and a processor generates a warning sound component through amplifying a sound feature point audio in a sound component according to warning voiceprint data and generates non-warning sound components through suppressing or shielding the sound feature point audio in the other sound components according to non-warning voiceprint information. Then the processor combines the warning sound component and the non-warning sound components to generate an output sound signal, allowing a speaker to output the output sound signal. Accordingly, the capturing device of the present disclosure provides instantly warning sound which is received (e.g. sound of car engine) from a remote range and outputs to allow the user in an early alert state, then reducing the probability of incident occurs thereby.
