Problem
Existing earphones lack waterproof functionality and adjustability for fitting the human body in special conditions such as swimming or outdoor rainy days.
Innovation Solution
A loudspeaker apparatus with a circuit housing, ear hook, and earphone core housing connected by a hinge component, featuring a waterproof housing protector and sealant to ensure water resistance and adjustability for fitting the user's ears.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If earphones are designed for ordinary use, then they are simple in structure, but they cannot provide waterproof function for special scenes like swimming or rainy days
Solution Approach 1:
The patent implements waterproofing by nesting a waterproof protective case around the earphone主体结构. The protective case encapsulates the earphone housing, circuit board, and battery, creating a nested structure where the inner earphone components are protected by the outer waterproof shell. This allows the earphone to gain waterproof functionality without fundamentally redesigning the internal structure.
Solution Approach 2:
The patent divides the earphone into separable components: a waterproof protective case and an earphone housing that can be detached. The protective case includes a waterproof seal at the opening where the earphone housing is inserted. This segmentation allows the waterproof function to be added as a separate layer without complicating the internal earphone structure.
2Adaptability or versatility
If earphones have fixed position, then they are simple to manufacture, but they cannot adjust to fit different user ear shapes and positions
Solution Approach 1:
The patent introduces a hinge component that enables dynamic adjustment of the earphone housing position relative to the protective case. The hinge allows the housing to rotate between a first position (in front of the ear) and a second position (behind the ear), providing adaptability to different user preferences and ear shapes without requiring multiple fixed-design models.
Solution Approach 2:
The hinge mechanism provides multi-functionality by enabling the earphone to serve multiple wearing configurations (in-ear and behind-ear positions). This single design can accommodate different user needs and ear anatomies, making the product universally adaptable without requiring separate manufacturing lines for different styles.
3Adaptability or versatility
If the earphone core housing is fixed relative to the ear hook, then the structure is stable, but it cannot rotate to change position for fitting in front of or behind the ear
Solution Approach 1:
The hinge component transforms the fixed connection into a dynamic joint that allows controlled rotation. The hinge maintains structural integrity through its mechanical design while enabling angular movement between the earphone housing and protective case, resolving the conflict between stability and position adjustability.

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.
