Solution Overview
Problem
Conventional earphones either shield external sounds, causing discomfort in quiet environments or allow interference from external noise in noisy environments, requiring users to carry multiple earphones for different settings, increasing cost and inconvenience.
Innovation Solution
A multifunctional bone conduction earphone with adjustable speaker position mechanisms that allow users to switch between air and bone conduction modes based on environmental noise levels, using damping and gear set mechanisms to position speakers for optimal sound transmission and interference reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If air conduction earphone is used to shield external sounds, then sound reception is improved, but external useful sounds are blocked and ear discomfort occurs
Solution Approach 1:
The earphone structure includes adjustable components that allow dynamic reconfiguration between closed and open states. The ear hanger body and speaker body can be adjusted to change the sealing state of the ear canal, enabling the earphone to adapt between noise isolation mode and environmental awareness mode.
Solution Approach 2:
The earphone is designed to perform multiple functions by integrating both noise isolation capability and environmental sound transmission capability into a single device. Users can switch between different conduction modes (air conduction and bone conduction) and adjust the sealing state to suit different environmental conditions.
2Adaptability or versatility
If bone conduction earphone is used to allow external sounds, then environmental awareness is improved, but external noise interference increases in noisy environments
Solution Approach 1:
The adjustable structure allows the earphone to dynamically transition between open and closed states. In noisy environments, users can adjust the earphone to a closed state that blocks external noise while maintaining bone conduction functionality, thus reducing noise interference while preserving environmental awareness capability when needed.
Solution Approach 2:
The earphone applies different sound conduction methods to different pathways: bone conduction for primary audio transmission through the skull, and selective air conduction for environmental sounds. The adjustable structure controls which pathway is active based on environmental conditions.
3Adaptability or versatility
If user carries two pairs of earphones for different environments, then adaptability is improved, but cost and convenience deteriorate
Solution Approach 1:
The earphone integrates multiple conduction modes (air conduction and bone conduction) and multiple operational states (closed and open) into a single device. This eliminates the need for users to carry multiple specialized earphones for different environments, reducing both cost and device complexity while maintaining full adaptability.
Solution Approach 2:
The patent combines previously separate functions (noise isolation and environmental awareness) into a single unified earphone system. The adjustable structure merges the capabilities of what would otherwise require two different earphones into one versatile device.
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
Enables users to select the appropriate conduction mode for different environments with a single pair of earphones, reducing noise interference and discomfort by adjusting speaker positions to shield or allow external sounds, enhancing sound quality through the combination of bone and air conduction modes.
Implementation Method 1
The left speaker position adjustment mechanism is a left damping adjustment mechanism; and/or the right speaker position adjustment mechanism is a right damping adjustment mechanism
Implementation Method 2
The second kind of earphones is a bone conduction earphone, which is in contact with human skin; and vibration waves pass through the human skin and bones, and then are transmitted into the cochleae and auditory nerves
Implementation Method 3
The first kind of earphones is an air conduction earphone, which is generally in-ear or covers the whole ear; the air conduction earphone emits sound waves, which pass through external auditory canals and act on eardrums

AI summary
The present invention discloses a multifunctional bone conduction earphone, including a left earphone body, a right earphone body and speaker position adjustment mechanisms. The left earphone body includes a left ear hanger body; the right earphone body includes a right ear hanger body; and the speaker position adjustment mechanisms are arranged on the ear hanging bodies and used for adjusting positions of speaker bodies. In a relatively noisy environment, the speaker position adjustment mechanisms are adjusted, so that the speaker bodies cover ears, thereby playing a role of shielding external sounds and avoiding interference from the external sounds.
