Earphone Noise Reduction via Inter-Device Voice Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In noisy environments, it is difficult for individuals to hear each other clearly, especially in workplaces with noise levels exceeding 80 db, where traditional methods require louder voices but still result in poor communication clarity.
Innovation Solution
An earphone communication method that detects conversation requirements, scans for target devices within a preset range, sends conversation requests, establishes voice communication connections, and applies noise reduction to voice data transmission, ensuring clear voice output even in noisy conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If people use a louder voice to talk in a noisy environment, then they can be heard more easily, but the communication clarity does not improve and health damage occurs
Solution Approach 1:
The patent introduces an intermediary communication system consisting of first and second communication devices that mediate the communication between users in noisy environments. Instead of directly shouting to be heard, users speak into their respective communication devices, which then transmit the audio signals electronically to each other, eliminating the need for loud voices while maintaining communication clarity.
Solution Approach 2:
The patent replaces the mechanical acoustic transmission system (direct voice propagation through air) with an electronic communication system. The communication devices capture, process, and transmit audio signals electronically, substituting the natural acoustic field with an engineered electronic transmission channel that is immune to environmental noise interference.
2Reliability
If noise reduction processing is applied to voice data, then communication clarity improves, but processing time and computational resources increase
Solution Approach 1:
The patent performs noise reduction processing on the voice data before transmission occurs. By preprocessing the audio signal to remove noise components in advance, the system ensures that clear voice data is transmitted to the receiving device, thereby improving communication clarity while minimizing real-time processing delays during actual communication.

AI summary
Disclosed are an earphone communication method, an earphone device, and a computer-readable storage medium. The method includes: when a conversation requirement of a first user is detected, detecting target devices within a preset range around a first earphone device; sending a conversation request to each target device, so that each target device determines whether to accept the conversation request; establishing a voice communication connection with a second earphone device in each target device that determines acceptance of the conversation request; and under the voice communication connection, performing noise reduction on voice data picked up by a microphone in the first earphone device and then sending the voice data to the second earphone device, so that the second earphone device outputs the received voice data.
