Vehicle Display Angle Control for Consistent Cabin Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle sound systems with foldable display devices often result in varying sound quality for passengers due to differing inclination angles of the display panel across rear seats, leading to inconsistent audio experiences for those in second-row and third-row seats.
Innovation Solution
A sound control apparatus with a variable-angle display panel, an angle detector, and a controller that adjusts sound settings based on the detected angle to ensure consistent audio quality across all seats.

Engineering Contradiction Analysis
1Manufacturing precision
If the display panel is fixed at a single inclination angle, then the structure is simple and manufacturing is easy, but passengers in different rows (second-row and third-row) experience different sound quality
Solution Approach 1:
The display panel's inclination angle is made variable rather than fixed. The panel can be adjusted between a first inclination angle (when opened) and a second inclination angle (when closed), allowing the sound output direction to adapt to different passenger positions in second-row and third-row seats, thereby resolving the sound quality inconsistency issue
Solution Approach 2:
The inclination angle parameter of the display panel is changed based on operational state. When the display device is opened, the panel is positioned at a first inclination angle optimized for second-row passengers; when closed, it transitions to a second inclination angle suitable for third-row passengers, dynamically optimizing sound quality for different configurations

AI summary
A sound control apparatus includes: a display panel that is supported by a base provided in a vehicle in a manner in which an angle of the display panel relative to the base is variable; an angle detector configured to detect the angle; and a controller configured to change sound setting in a cabin of the vehicle in accordance with the angle.
