Audio Control System for Electromagnetic Cradle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic cradles require manual button operation to control functions like music playback and cradle movement, which is inconvenient for users.
Innovation Solution
An audio control system that uses audio signals to identify and execute commands for controlling the cradle's functions, comprising an audio transmitting and receiving unit, a cloud server, and a function execution unit, allowing users to control the cradle's operations through voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button operation is used to control cradle functions, then the device structure remains simple, but the ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical button operation system with an acoustic control system. The audio receiving module captures voice commands, which are then processed by the control module to execute corresponding functions. This substitution eliminates the need for physical button manipulation, significantly improving ease of operation while introducing acoustic sensing and processing components.
Solution Approach 2:
The patent introduces an audio signal as an intermediary between the user and the cradle control system. Instead of direct mechanical interaction through buttons, the user's voice is converted into audio signals that the system interprets and acts upon. This intermediary layer enables more natural and convenient interaction while requiring additional audio processing components.
2Ease of operation
If audio control with cloud server is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The cloud server acts as an external intermediary that handles complex audio processing and command interpretation tasks. The local control module communicates with the cloud server via network connection, offloading the computational burden of voice recognition and command mapping to remote servers. This approach improves ease of operation while managing device complexity by distributing system functions across local and remote components.

AI summary
An audio control system of an electromagnetic cradle includes an audio transmitting and receiving unit, a cloud server, and a function execution unit. The audio transmitting and receiving unit receives an audio command emitted from a user. The cloud server is connected with the audio transmitting and receiving unit through a network. The cloud server identifies and compares the audio command of the audio transmitting and receiving unit. The function execution unit is connected with the cloud server through the network. The function control module is driven by function indication of the cloud server to execute related functions, including playing the music, lighting or shaking the cradle.
