Earbud EQ Control With On-Device Real-Time Audio Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio systems require users to divert attention from listening to adjust sound attributes like volume and equalization settings, leading to latency and inefficiency, as these settings are typically controlled through applications on audio sources rather than directly on wearable devices.
Innovation Solution
Incorporating a speaker device with a user input terminal, processor, and memory that allows users to directly adjust sound attributes such as volume and equalization settings on the device itself, enabling local processing and adjustment of audio signals without needing to access external applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users control sound attributes through applications on audio sources, then sound customization is achieved, but user attention is diverted from listening and latency increases
Solution Approach 1:
The wearable speaker device enables users to control sound attributes directly on the device itself through integrated user input terminals, allowing the device to serve its own control functions without requiring external audio source applications. This self-service capability eliminates the need for users to divert attention to their phones or other audio sources, maintaining focus on listening while reducing control latency.
Solution Approach 2:
The patent introduces a wireless communication interface as an intermediary between the audio source and the wearable speaker device. This intermediary enables direct transmission of audio signals and control commands to the wearable device, allowing users to adjust sound attributes locally without routing control through external applications, thereby reducing latency and improving responsiveness.
2Adaptability or versatility
If users control sound attributes through external applications, then sound customization is possible, but user convenience deteriorates due to needing to access external devices
Solution Approach 1:
The wearable speaker device integrates multiple functions including audio playback, sound attribute control, and user input processing within a single device. This multi-functionality allows users to adjust volume, equalization, and other sound attributes directly on the wearable device without needing to access external applications or devices, significantly improving user convenience while maintaining full sound customization capabilities.
Solution Approach 2:
The device incorporates integrated user input terminals and local processing capabilities, enabling it to handle its own control functions independently. Users can interact with the wearable device directly through touch interfaces or other input mechanisms built into the device, eliminating the need to reach for external devices and making the device self-sufficient for all audio control needs.
3Ease of operation
If sound attributes are adjusted on wearable devices, then latency is reduced and user convenience is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical control systems with wireless communication and digital signal processing. Instead of using physical connections or complex hardware controls, the device utilizes wireless interfaces to receive audio signals and digital processing to handle sound attribute adjustments. This substitution reduces mechanical complexity while enabling real-time control capabilities and improving user convenience.
