Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone conduction earphones have ear hook structures that are not compact, which affects their portability and miniaturization.
Innovation Solution
A bone conduction earphone design featuring a loudspeaker assembly and an ear hook assembly with a first and second ear hook housing connected by a connection member, where the housings are spliced and matched to form an accommodating space with restricted movement along specific directions, and include slots and blocks for enhanced stability and a connection assembly with slots and blocks to restrict movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the ear hook structure is made compact for portability and miniaturization, then the portability is improved, but the structural stability may deteriorate
Solution Approach 1:
The ear hook is divided into multiple housing segments (first housing, second housing, third housing) that are spliced together. This segmentation allows each segment to be optimized for compactness while the collective assembly maintains structural stability through precise splicing connections.
Solution Approach 2:
The housing segments are designed to fit together in a nested or interlocking manner, with each segment containing or supporting the next. This nesting approach maximizes space utilization and achieves miniaturization while maintaining overall structural integrity.
2Volume of moving object
If the ear hook structure is made compact, then the portability is improved, but the connection reliability may deteriorate
Solution Approach 1:
Connection structures such as slots and blocks are pre-designed and pre-positioned in the housing segments before assembly. This preliminary action ensures that when the segments are spliced together, the connections are immediately reliable and stable, maintaining connection reliability despite the compact size.
Solution Approach 2:
Connection elements such as adhesive layers, mechanical interlocks, or fastening structures act as intermediaries between the housing segments. These intermediaries ensure reliable connection between the compact segments, maintaining connection reliability while enabling miniaturization.
3Volume of moving object
If the housing segments are spliced together to form accommodating space, then the compactness is improved, but the manufacturing complexity may deteriorate
Solution Approach 1:
The housing is segmented into modular units that can be manufactured separately using standardized processes, then assembled through simple splicing operations. This segmentation reduces manufacturing complexity by allowing each segment to be produced independently with consistent tolerances.
Solution Approach 2:
The splicing connection design serves multiple functions: it joins housing segments, defines accommodating spaces, and provides structural support. This multi-functionality reduces the need for additional components or complex assembly steps, thereby reducing overall manufacturing complexity.

AI summary
The present disclosure discloses a bone conduction earphone. The bone conduction earphone may include a loudspeaker assembly. The bone conduction earphone may also include an ear hook assembly including a first ear hook housing, a connection member, and a second ear hook housing. One end of the connection member may be connected to the first ear hook housing, and the other end of the connection member may be connected to the loudspeaker assembly. The first ear hook housing may include a first sub-accommodating space, and the second ear hook housing may include a second sub-accommodating space. The first ear hook housing may be spliced and matched with the second ear hook housing by a first connection assembly such that the first sub-accommodating space and the second sub-accommodating space may be combined to form an accommodating space, and a length direction of the accommodating space may be perpendicular to a thickness direction of the accommodating space.
