Rotatable Display Speaker Mounting for Consistent Sound Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In rotatable image display devices, the change in speaker orientation with device rotation affects sound delivery to the user, leading to inconsistent audio experience.
Innovation Solution
The image display device incorporates a support component that fixes the speakers to the rear surface of the device body, allowing them to emit sound towards the placement surface, maintaining consistent sound delivery regardless of the device's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the speaker is fixed to the device body, then the device structure is simple, but the sound delivery changes when the device is rotated
Solution Approach 1:
The speaker is extracted from the device body and mounted separately on the stand via the support component. This separation allows the speaker to maintain a fixed orientation relative to the placement surface while the device body can be rotated, thus maintaining consistent sound delivery without complicating the overall device structure
Solution Approach 2:
The support component acts as an intermediary between the stand and the speaker. It provides a stable mounting platform that keeps the speaker at a fixed position and orientation relative to the placement surface, decoupling the speaker's orientation from the device body's rotation
2Area of stationary object
If the speaker is disposed on the rear surface of the device body, then the front surface is unobstructed, but the speaker orientation changes with device rotation
Solution Approach 1:
The speaker is taken out from the device body structure and mounted independently on the stand. This allows the front surface of the device body to remain completely unobstructed while the speaker maintains a stable, fixed orientation relative to the placement surface through the support component
Solution Approach 2:
The speaker mounting is moved from the device body (one dimension of rotation) to the stand base (different dimensional reference). By mounting the speaker on the stand via the support component rather than on the rotatable device body, the speaker's orientation is stabilized in a different dimensional reference frame

AI summary
An image display device includes a device body having a front surface with a display surface that is substantially rectangular and is for displaying an image; a stand that is placed on a placement surface and supports the device body; a support component that is fixed to the stand, is disposed on a rear surface of the device body, and rotatably supports the device body about a rotation shaft between a horizontal orientation in which the display surface is in a landscape orientation and a vertical orientation in which the display surface is in a portrait orientation; and a speaker that is supported by the support component and is disposed on the rear surface of the device body via the support component. The speaker emits sound toward the placement surface.
