Speaker EQ Control With On-Device Input and Low-Latency Processing
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 by using applications on connected devices, leading to latency and inefficiency.
Innovation Solution
Incorporating user input terminals directly on speaker devices, such as earbuds or headphones, to receive and process user inputs for sound adjustments, allowing users to control EQ settings locally without needing to access external applications, using integrated circuitry and processors for real-time audio signal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users control sound attributes using applications on connected devices, then sound attribute adjustment capability is provided, but user attention is diverted from listening and latency increases
Solution Approach 1:
The patent combines the audio processing functions and control interface into the speaker device itself. The speaker device includes a processor that receives audio signals and applies sound attributes locally, and a user interface that allows direct control of these attributes. This merging eliminates the need for separate connected devices and applications, enabling users to control sound attributes directly at the audio output point without diverting attention or experiencing latency.
2Ease of operation
If users control sound attributes using applications on connected devices, then sound attribute adjustment capability is provided, but operational efficiency decreases
Solution Approach 1:
The speaker device is designed to be self-sufficient for sound attribute control. It includes its own processor for applying sound attributes to audio signals and its own user interface for controlling these attributes. This self-service capability allows the device to operate independently without requiring external connected devices or applications, thereby improving operational efficiency and user convenience.
3Adaptability or versatility
If equalization is implemented using filters in traditional equalizers, then frequency response adjustment is achieved, but device complexity increases
Solution Approach 1:
The patent replaces traditional hardware-based equalizer circuitry with software-based processing. The processor in the speaker device applies digital filters and signal processing algorithms to adjust the frequency response. This substitution of mechanical/electrical equalizer components with software-based processing reduces device complexity while maintaining or enhancing frequency response adjustment capabilities.
