Earphone Acoustic Echo Impulse Response Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current earphone control methods for music and call operations are cumbersome and prone to incorrect operations, as users need to manually interact with specific buttons or app pages, reducing efficiency and convenience.
Innovation Solution
A method that uses an earphone to determine the acoustic echo impulse response based on audio signals and user input vibrations, allowing for the identification of directive instructions to control corresponding operations in connected electronic devices, such as playing, pausing, or adjusting volume, without requiring direct button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users perform operations on preset control buttons of the earphone, then control operations can be executed, but users may trigger wrong control operations and operation efficiency is reduced
Solution Approach 1:
The patent replaces mechanical button pressing with acoustic field interaction. The earphone uses a microphone to detect acoustic signals (clapping, whistling, humming) generated by user actions in the acoustic field, converting acoustic energy into control commands. This eliminates the need for physical contact with buttons, thereby preventing wrong operations and improving efficiency.
Solution Approach 2:
The patent introduces acoustic signals as an intermediary between user intent and control execution. Instead of direct button contact, users generate acoustic signals (clapping, whistling, humming) that are captured by the microphone and translated into control commands. This intermediary layer ensures accurate intent recognition and prevents erroneous operations.
2Ease of operation
If users manually perform operations on the related page of the music application, then control operations can be executed, but the process becomes cumbersome
Solution Approach 1:
The patent replaces manual navigation through app pages with acoustic field-based control. Users perform natural actions (clapping, whistling, humming) that are detected by the microphone and converted into control commands, eliminating the need to manually navigate through app interfaces and saving time.
Solution Approach 2:
The earphone system automatically detects acoustic signals and translates them into control commands without requiring user intervention in the app interface. The system self-services by listening to user-generated acoustic signals and executing corresponding operations automatically, reducing both time and effort required for control operations.

Function Achieved in This Case
This method simplifies user interactions by accurately identifying input operations and executing corresponding actions for audio applications, enhancing user experience and efficiency by eliminating the need for manual button navigation.
Implementation Method 1
an acoustic echo impulse response at a position of the user's ear canal where the earphone currently stays is determined according to an audio signal currently played by the earphone and a vibration signal generated by the input operation
Data Source
AI summary
A method for processing audio signal, an electronic device, and an earphone are provided. The method includes the following. An input operation of a user performed on an earphone is received, and an acoustic echo impulse response at a position of the user's ear canal where the earphone currently stays is determined according to an audio signal currently played by the earphone and a vibration signal generated by the input operation. A directive instruction corresponding to the input operation is identified at least according to the acoustic echo impulse response. An electronic device in communication with the earphone is controlled to execute a corresponding operation for a preset application in the electronic device according to the directive instruction.
