Rotatable Loudspeaker Body with Motor-Driven Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loudspeakers often have fixed screens or operating panels and strong directivity in sound production, which can hinder convenience and playback effectiveness when not properly positioned.
Innovation Solution
A rotatable loudspeaker design with a motor-driven mechanism allowing the loudspeaker body to rotate around its base, enabling adjustment of the screen or speaker orientation to improve usability and sound directionality, along with a sliding display screen mechanism for enhanced user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen or operating panel is fixed on the loudspeaker, then the structure is simple and stable, but the convenience of use is reduced when not placed in position
Solution Approach 1:
The loudspeaker body is made rotatable relative to the base through a motor-driven mechanism, allowing the screen and speaker to dynamically adjust their orientation. This transforms the fixed structure into a dynamic one that can adapt to different usage scenarios, resolving the contradiction between operational convenience and structural simplicity.
2Reliability
If the speaker has strong directivity, then the sound quality is improved, but the playing effect is affected when not placed in position
Solution Approach 1:
The rotatable mechanism allows the speaker to dynamically adjust its orientation to maintain optimal sound directionality regardless of placement position. This preserves the benefits of strong directivity while gaining adaptability to different positions and usage scenarios.
3Adaptability or versatility
If the loudspeaker body is made rotatable, then the convenience of use and playing effect are improved, but the device complexity increases
Solution Approach 1:
The loudspeaker is divided into a fixed base and a rotatable body portion. This segmentation allows the rotation mechanism to be isolated to specific components, managing complexity by separating the static support structure from the dynamic functional elements.
Solution Approach 2:
A motor-driven transmission mechanism serves as an intermediary between the power source and the rotatable body. This intermediary component enables controlled rotation while managing the complexity of the mechanical structure through a dedicated drive system.
4Stability of the object's composition
If the center of gravity is lowered, then the placement stability is improved, but the structural design becomes more constrained
Solution Approach 1:
The base is designed with increased weight relative to the loudspeaker body, creating a counterweight effect that stabilizes the rotatable structure. This weight distribution prevents excessive rotation and maintains placement stability while enabling controlled movement.

Data Source
AI summary
A loudspeaker and an electronic system are disclosed. The loudspeaker includes a base, a loudspeaker body and a first driver. The loudspeaker body is disposed on the base and defines an up and down direction of the loudspeaker, and the loudspeaker body is rotatable around the up and down direction with respect to the base. The first driver can drive the loudspeaker body to rotate with respect to the base.
