Rotating Display Speaker Layout for Natural Audio in Any Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile display devices have limited mobility due to their size, and larger display devices require significant installation space, lacking convenient mobility and natural sound effects when rotated between landscape and portrait modes.
Innovation Solution
A display device with a rotatable head featuring pivotable speakers and sensors that adjust sound signals based on the device's orientation, ensuring optimal sound output and natural sound effects in both landscape and portrait modes by switching sound signals between speakers as the head rotates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display device is made larger to improve display quality, then the display performance is improved, but the mobility and installation space requirements deteriorate
Solution Approach 1:
The display device incorporates a rotatable head that can dynamically switch between landscape and portrait modes, allowing the device to adapt its orientation based on usage requirements. This dynamic capability enables a single device to serve multiple functions without requiring multiple fixed-size displays, thereby improving mobility while maintaining display quality.
2Device complexity
If speakers are fixed in position to simplify device structure, then the device complexity is reduced, but the sound effect quality deteriorates when the device rotates between modes
Solution Approach 1:
The speaker system is designed to dynamically switch sound output channels based on the detected orientation mode. In landscape mode, left and right speakers provide stereo sound, while in portrait mode, the system switches to upper and lower speaker output. This dynamic adaptation maintains optimal sound effects across different orientations without requiring complex physical repositioning mechanisms.
Solution Approach 2:
The system changes the operational parameters of the speaker system based on orientation. The processor detects the mode and switches between different sound signal configurations - using left/right channel assignment in landscape mode and upper/lower channel assignment in portrait mode. This parameter switching maintains sound quality without increasing physical device complexity.
3Ease of manufacture
If the device structure is simplified to reduce manufacturing cost, then the ease of manufacture is improved, but the adaptability to different orientations deteriorates
Solution Approach 1:
The display device is designed with universal adaptability to function effectively in both landscape and portrait orientations. The rotatable head, orientation sensor, and switchable speaker system work together to enable a single device structure to serve multiple orientation requirements, eliminating the need for separate devices for different modes and simplifying manufacturing while enhancing versatility.

AI summary
A display device includes a head including a display formed on a front surface thereof, a circumference having a pair of long sides and a pair of short sides, and one or more first speakers provided on a left short side and one or more second speakers provided on a right short side of the display and configured to be pivotable between a landscape mode in which the long sides are in a horizontal state and a portrait mode in which the long sides are in a vertical state, a sensor configured to detect pivot of the head, and a processor configured to determine a pivot state indicating whether the head is in the landscape mode or the portrait mode based on a result of detection and switch sound signals output by the first speakers and the second speakers when the pivot state of the head is switched.
