Waterproof Ear-Hook Loudspeaker With Rotating Core Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headphones lack waterproof functionality and adjustability for fitting the human body, making them unsuitable for special environments like swimming or outdoor rainy conditions.
Innovation Solution
A loudspeaker apparatus with a waterproof housing protector, a hinge component for adjusting the earphone core position, and a circuit housing that includes a circuit component and battery, along with a sealant to ensure waterproofing and secure fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ordinary headphones are used, then the device is simple and inexpensive, but it lacks waterproof functionality and cannot be used in special environments like swimming or rainy conditions
Solution Approach 1:
The patent implements a nested structure where the housing protector is placed inside the housing, creating a protective chamber that accommodates the loudspeaker component. This nested arrangement provides waterproof protection without significantly increasing the overall device volume, as the protector utilizes the internal space of the existing housing structure.
Solution Approach 2:
The housing protector is formed from a flexible waterproof material that can be molded to fit the internal contours of the housing. This flexible membrane approach provides effective waterproof sealing while maintaining a compact structure that does not substantially increase the device's external dimensions.
2Adaptability or versatility
If the earphone core housing is fixed to the ear hook, then the structure is simple, but it cannot adjust positions to fit different user preferences or body types
Solution Approach 1:
The patent replaces the fixed connection with a hinge component that enables rotational movement between the earphone core housing and the ear hook. This dynamic connection allows the housing to pivot and adjust to different positions, accommodating various user preferences and ear shapes while maintaining a relatively simple overall structure.
3Reliability
If a housing protector is added to provide waterproofing, then waterproof reliability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines the housing protector with the housing structure in a integrated assembly. The protector is positioned within the housing and secured through combined structural features, allowing the waterproof component and housing to be manufactured and assembled together in a streamlined process that reduces manufacturing complexity despite adding waterproof functionality.

AI summary
A loudspeaker apparatus includes a circuit housing configured to accommodate a circuit component or a battery; an ear hook; a housing of an earphone core configured to accommodate the earphone core; and a housing protector at least partially covering a periphery of the circuit housing and the ear hook. A first end of the ear hook is connected to the circuit housing. The earphone core is driven by the circuit component or the battery to vibrate to generate sound. The housing of the earphone core is connected to a second end of the ear hook away from the circuit housing through a hinge component. The hinge component is capable of rotating to change a position of the housing of the earphone core relative to the ear hook.
