Solution Overview
Problem
Conventional sound receiving devices, such as hearing aids, face operational inconveniences due to small buttons or knobs, leading to a poor user experience.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buttons or knobs are installed on the hearing aid for manual control, then the device can provide scene mode selection and volume control functions, but the device size becomes larger and operation becomes inconvenient
Solution Approach 1:
The patent replaces mechanical control elements (buttons, knobs) with a voice-based control system. The hearing aid captures voice signals through its microphone, processes them to recognize control commands, and executes corresponding operations. This substitution eliminates the need for physical control elements, maintaining device compactness while significantly improving operation convenience for users with hearing or dexterity issues
Solution Approach 2:
The patent introduces voice signals as an intermediary between the user and the device control system. Instead of direct mechanical interaction, the user's speech serves as the mediator that triggers control functions. The voice signal is captured, processed through signal processing algorithms, and translated into control commands, providing an indirect but more accessible control mechanism
2Adaptability or versatility
If more control functions are added to the hearing aid, then user needs are better met, but device complexity increases
Solution Approach 1:
The patent implements a universal voice-based control interface that can handle multiple control functions (scene mode selection, volume adjustment, program switching, etc.) through a single unified mechanism. Instead of adding separate physical controls for each function, the voice recognition system serves as a multi-functional controller, reducing structural complexity while expanding functional versatility
Solution Approach 2:
The patent changes the control parameter from mechanical position (button presses, knob rotations) to acoustic parameters (voice frequency, amplitude, temporal patterns). This parameter transformation allows diverse control functions to be achieved through variations in voice characteristics rather than through complex mechanical configurations, simplifying the device architecture
3Ease of operation
If voice-based control is implemented, then operation convenience is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic sampling of voice signals rather than continuous processing. The system activates the voice recognition function only when triggered by specific acoustic events or at scheduled intervals, allowing the device to return to low-power states between activations. This periodic operation mode significantly reduces average power consumption compared to continuous signal processing
Solution Approach 2:
The patent applies partial processing to voice signals by first performing simple feature extraction and preliminary analysis before full recognition processing. Only signals that meet certain criteria (e.g., sufficient energy, specific frequency ranges) undergo complete processing, while others are quickly discarded. This selective processing approach reduces overall computational load and power consumption

AI summary
This application relates to a method and an apparatus for controlling a sound receiving device based on a dual-mode audio three-dimensional code and a method and an apparatus for parsing a control signal of a sound receiving device based on a dual-mode audio three-dimensional code. The method includes: receiving an operation instruction and encoding the operation instruction as a digital vector; obtaining a first audio three-dimensional code corresponding to a preset speech signal, and encoding the digital vector into the first audio three-dimensional code to obtain a second audio three-dimensional code; and converting the second audio three-dimensional code into a speech signal and sending the speech signal to a sound receiving device. In the method, operation convenience can be improved, and an instruction operation can be performed without arrangement of any additional module.
