Underwater Speaker With Graphic Mapping Lampshade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth speakers for swimming pools with lighting effects can only achieve a single light and shadow effect using a water textured lampshade, which fails to meet user demands for complex or multi-element light and shadow effects, and are prone to sound quality issues due to water adherence.
Innovation Solution
An underwater speaker design featuring a lampshade with a graphic mapping unit inside the outer shell, where a luminescent body emits light that is mapped onto the water or wall through the lampshade and shell, creating complex light and shadow effects, while a flexible protective cover on the speaker prevents water from affecting sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a water textured lampshade is used to create light and shadow effects, then the light and shadow effect is achieved, but the structure becomes complex and only single-element effects can be realized
Solution Approach 1:
The lampshade is divided into multiple independent graphic mapping units (first, second, third mapping units) with different patterns. Each mapping unit can be independently controlled to display different light and shadow effects, allowing single-element, multi-element, and complex pattern effects without requiring a completely complex overall structure.
Solution Approach 2:
The lampshade incorporates adjustable graphic mapping units that can dynamically change their patterns and illumination states. The mapping units can switch between different graphic patterns and illumination modes, enabling the system to adapt to various effect requirements without permanent structural complexity.
2Reliability
If a protective cover is added to prevent water adherence, then sound quality is improved, but the device complexity increases
Solution Approach 1:
A flexible protective cover is added over the speaker diaphragm. This thin film structure prevents water from directly contacting the diaphragm while maintaining acoustic transparency, allowing sound waves to pass through effectively. The flexible nature of the cover enables it to conform to the diaphragm shape without creating rigid structural additions.
Solution Approach 2:
The protective cover acts as an intermediary layer between the speaker diaphragm and the water environment. It mediates the interaction by blocking water adherence while allowing acoustic energy transmission, thus protecting the sound quality without requiring direct water-proofing of the diaphragm itself.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the multiplicity and effect of light and shadow effects, meeting user needs for complex and multi-element displays, and improves sound quality by preventing water from adhering to the speaker's diaphragm.
Implementation Method 1
a luminescent body arranged on the circuit board, and the luminescent body is oriented towards the interior of the lampshade
Implementation Method 2
a graphic mapping unit formed on the lampshade... When the luminescent body emits light, the light can be mapped onto the water, ground, or wall through the lampshade and the outer shell
Implementation Method 3
a flexible protective cover arranged on the diaphragm of the speaker, with the protective cover protruding towards the direction of the sound outlet

AI summary
The present disclosure provides an underwater speaker. The underwater speaker includes an outer shell, with a circuit board arranged inside, a speaker, and a lampshade with a first opening at the top. The speaker is electrically connected to the circuit board. The luminescent body is arranged on the circuit board. The luminescent body is oriented towards the interior of the lampshade, and a graphic mapping unit is formed on the lampshade. This embodiment uses the speaker to play audio and achieve the function of an underwater speaker. When the luminescent body emits light, the light can be mapped onto the water. This improves the multiplicity and effect of light and shadow, and meets users' needs for complex and multi-element light and shadow effects.
