Rotatable Plate Audio Output Device for Adjustable Sound Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio output devices do not adequately accommodate individual differences in sound perception and device positioning, requiring users to move the entire device for optimal listening experience.
Innovation Solution
An audio output device with a speaker unit, first and second plates, where the sound-emitting surface has adjustable sound transmission paths via rotatable connections, allowing users to direct sound output without moving the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the audio output device uses a fixed sound transmission path, then the device structure is simple, but the listening experience cannot be optimized for different users and positions
Solution Approach 1:
The patent applies the dynamics principle by making the sound transmission path adjustable through rotatable plates. The first and second plates can rotate relative to the speaker unit and each other, allowing the sound outlet direction to be dynamically changed according to different listening positions and user preferences, thus resolving the contradiction between fixed structure and adaptability.
2Ease of operation
If the entire electronic device is moved to optimize listening experience, then the sound direction can be adjusted, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent applies segmentation by separating the sound direction adjustment function from the entire device. Only the first and second plates need to be rotated to change sound direction, while the main device remains stationary. This localized adjustment significantly reduces the time and effort required compared to moving the entire electronic device.
3Adaptability or versatility
If the sound outlet direction is fixed, then the device structure is simple, but it cannot accommodate individual differences in sound perception
Solution Approach 1:
The patent implements dynamics by enabling the sound transmission path to be adjusted according to different listening positions and user preferences. The rotatable first and second plates allow the sound outlet direction to be dynamically modified, accommodating individual differences in sound perception without requiring a completely complex adjustment mechanism.

AI summary
The present invention provides an audio output device. The audio output device includes a speaker unit, a first plate and a second plate. The speaker unit has a sound-emitting surface, and the sound-emitting surface has a first side and a second side opposite to each other. A first side edge of the first plate corresponds to the first side and is rotatably connected. A second side of the second plate corresponds to the second side and is rotatably connected, and a sound channel corresponding to the speaker unit is formed between the first plate and the second plate, and a sound outlet is formed at an end of the sound channel farthest away from the speaker unit, and a direction pointed by a connection line between a center point of the sound-emitting surface and a center point of the sound outlet is adjustable.
