Lantern Speaker Antenna Layout for Protection and Stable Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio output devices do not effectively combine a lantern function with audio output capabilities, particularly in camping or disaster scenarios, where both illumination and sound are needed, and often lack stability and usability features.
Innovation Solution
An audio output device with a lantern part, an antenna part, and a control part that extends along a first axis, allowing light irradiation and sound output, with the antenna part also serving as a protective feature and the control part managing both light and audio functions, and a mounting unit for a battery pack to improve stability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the antenna part is positioned close to the lantern part for compact design, then device complexity is reduced, but the lantern part becomes vulnerable to external impact
Solution Approach 1:
The antenna part serves as an intermediary protective element positioned between the external environment and the lantern part. It functions dually as both a protective barrier against external impact and as a functional antenna for receiving radio waves, thereby protecting the lantern without requiring additional protective structures.
2Length of stationary object
If the battery pack is positioned at the top of the device, then the overall height is reduced, but the device becomes unstable when placed
Solution Approach 1:
The battery pack is positioned at the bottom of the device to act as a counterweight, lowering the center of gravity and improving stability. This weight distribution compensates for the reduced height, ensuring the device remains stable when placed on surfaces while maintaining a compact overall dimensions.
3Ease of manufacture
If the audio output part is positioned below the control part, then manufacturing is simplified, but sound propagation to surroundings is reduced
Solution Approach 1:
The audio output part is inverted to the top position of the device, opposite to the conventional placement below the control part. This inversion allows sound to propagate more effectively to the surroundings by positioning the speaker at the highest point, improving acoustic performance while maintaining manufacturing simplicity through standardized component placement.

AI summary
An audio output device has a lantern part extends along a first axis, an antenna part, an audio output part, and a control part. The antenna part has a first end and a second end that are respectively connected to a first side and a second side relative to a central part of the lantern part in a first direction parallel to the first axis. A portion of the antenna part between the first end and the second end extends in the first direction and is spaced apart from the lantern part in a direction orthogonal to the first direction. The control part is configured to cause the audio output part to output sound corresponding to a radio broadcasting wave received by the antenna part.
