Bone Conduction Earphone Auricle Clamping Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bone conduction earphones suffer from poor wearing stability due to the wire connecting the left and right earphones, which affects their fit and sound transmission.
Innovation Solution
A bone conduction earphone design featuring an earphone body attached to the auricle with an ear hook that extends laterally and deviates between the auricle and the head, clamping the auricle for improved stability, and incorporating an arc-shaped main hook body made of elastic plastic for a secure fit, along with a power supply component and conductive wire for connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the left earphone and right earphone are connected by a wire, then connectivity is achieved, but wearing stability deteriorates due to wire dragging on the hair or neck
Solution Approach 1:
The patent extracts and removes the connecting wire from the earphone system, transitioning to a wireless design where each earphone operates independently with its own power supply and audio processing capabilities, thereby eliminating the wire that caused wearing instability while maintaining full functionality
Solution Approach 2:
The patent divides the previously unified wired earphone system into two independent wireless earphone units, each with separate power supplies and control circuits, allowing them to function autonomously without physical connection, thus improving wearing stability while maintaining connectivity through wireless communication
2Ease of operation
If the earphone is simply hooked on the auricles, then ease of wearing is improved, but wearing stability deteriorates
Solution Approach 1:
The patent employs an ear hook with an arc-shaped main body that conforms to the natural curvature of the human ear, allowing the earphone to be securely hooked on the auricle while maintaining comfort and ease of wearing, thereby improving wearing stability without compromising ease of operation
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
Enhances wearing stability and sound quality by securely clamping the auricle, eliminating the need for a connecting wire and improving user experience through wireless True Wireless Stereo technology.
Implementation Method 1
the main hook body is made of elastic plastic material
Implementation Method 2
Bone conduction is a way of sound conduction, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through human skull, bone labyrinth, inner ear lymph, spiral organs, and auditory center

AI summary
A bone conduction earphone includes an earphone body configured to attach to an auricle of a human body and transmit an audio vibration signal and an ear hook configured to hook on the auricle. A first end of the ear hook is fixedly connected with the earphone body. A second end of the ear hook extends between the auricle and a head of the human body. The second end of the ear hook extends along the auricle and laterally deviates from the earphone body. In a natural state, a lateral distance between the earphone body and an extending end of the ear hook is less than a lateral distance from a front surface of the auricle to a back surface of the auricle. When the bone conduction earphone is worn, the earphone body and the ear hook clamp the auricle.
