Speaker Output Adjustment for Input Location Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices struggle to provide effective sound feedback for user inputs, such as touch or pen interactions, as the speaker output is not adjusted based on the location of the input signal, leading to unclear and unhelpful sound effects.
Innovation Solution
An electronic device with a processor that adjusts the speaker output based on the distance between the input signal generation location and the speaker location, using a method that calculates and applies weights to each speaker to simulate sound effects similar to handwriting or hovering interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker output is kept constant regardless of input location, then the device structure remains simple, but the sound feedback becomes unclear and unhelpful
Solution Approach 1:
The patent applies local quality by adjusting the output of each speaker based on its specific distance to the input location. Each speaker's output is individually controlled according to its spatial relationship with the touch or pen input point, creating location-specific sound feedback that enhances clarity and realism.
Solution Approach 2:
The system dynamically adjusts speaker output levels in real-time based on the input location. As the user moves their finger or pen across the display, the speaker outputs are continuously recalculated and adjusted to maintain appropriate feedback clarity for each new position.
2Reliability
If multiple speakers are used to simulate handwriting effects, then the sound feedback realism improves, but the device complexity increases
Solution Approach 1:
The patent segments the sound output function across multiple speakers distributed around the device. Each speaker handles a portion of the sound feedback task, with its output level determined by its distance to the input location. This segmentation enables realistic spatial audio effects while distributing the complexity across multiple simple components.
Solution Approach 2:
The system changes the output parameter of each speaker based on its spatial parameter (distance to input location). By varying the output level according to distance, the system creates realistic sound effects that mimic handwriting or hovering interactions without requiring complex speaker hardware.

AI summary
An electronic device includes a speaker, an input device, and a processor electrically connected with the speaker and the input device. The processor adjusts the output of the speaker based on a generation location of the input signal received through the input device and the location of the speaker.
