Voice Controlled Media Player Switch Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling digital audio devices, such as karaoke systems, require user activation of media player terminals or remote controls, which can be inconvenient, especially when users lack access to control buttons or when using a remote control diminishes the user experience.
Innovation Solution
A system and method for voice-controlled operation of a media player that detects the positioning of a microphone power switch to enter a voice recognition mode, allowing users to provide voice commands to control the media player without physical buttons or remote controls, using a microphone to detect and process voice commands for controlling media player functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional remote control or terminal buttons are used for media player control, then control functionality is provided, but user convenience deteriorates due to lack of access to control buttons or diminished user experience
Solution Approach 1:
The patent replaces mechanical control interfaces (remote controls and terminal buttons) with voice-based acoustic control. The media player detects voice commands through a microphone, processes them via speech recognition, and executes corresponding operations, thereby eliminating the need for physical mechanical interaction and significantly improving ease of operation.
2Adaptability or versatility
If voice recognition mode is enabled through microphone power switch positioning, then hands-free control is achieved, but additional detection steps are required
Solution Approach 1:
The system utilizes the existing microphone power switch for dual purposes: its original function of controlling microphone power and a secondary function of triggering voice recognition mode. When the switch is positioned to turn the microphone on, the system simultaneously detects this state and automatically enters voice recognition mode without requiring separate controls or complex detection mechanisms, thereby achieving hands-free control while maintaining simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and intuitive user control of media players through voice commands, enhancing user experience by allowing operation without physical interfaces, particularly beneficial for karaoke and interactive entertainment systems.
Implementation Method 1
detecting one or more output signals of the microphone, detecting a voice command based on the one or more output signals of the microphone
Data Source
AI summary
A system and methods for voice controlled operation of a media player are provided. In one embodiment, a method includes detecting user positioning of a microphone power switch to an off position, detecting user positioning of the microphone power switch to an on position within a predetermined period of time and entering a voice recognition mode, by the media player, based on the user positioning of the microphone power switch to the on position within the predetermined period of time. The method may further include detecting one or more output signals of the microphone, detecting a voice command based on the one or more output signals of the microphone, and controlling operation of the media player based on the voice command, wherein the media player outputs a graphical display associated with the voice command.
