Multi-modal audio system with automatic usage mode detection and configuration capability
View Patent ↗An audio system that may be used in multiple modes or use scenarios, while still providing a user with a desirable level of audio quality and comfort. The inventive system may include multiple components or elements, with the components or elements capable of being used in different configurations depending upon the mode of use. The different configurations provide an optimized user audio experience for multiple modes of use without requiring a user to carry multiple devices or sacrifice the audio quality or features desired for a particular situation. The inventive audio system includes a use mode detection element that enables the system to detect the mode of use, and in response, to be automatically configured for optimal performance for a specific use scenario. This may include, for example, the use of one or more audio processing elements that perform signal processing on the audio signals to implement a variety of desired functions (e.g., noise reduction, echo cancellation, etc.).
