Oral-Cavity Vocalization Device With Rear Passage for Explosive Sounds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vocalization assistance devices struggle to produce original sounds on the rear side of the oral cavity, particularly for individuals with larynx extraction or tracheal incision, making it difficult to articulate explosive sounds and consonants like [k].
Innovation Solution
A vocalization assistance device with a mounting body and diaphragm positioned in the oral cavity, featuring a speaker and passage that outputs sound to the rear side, allowing for the production of original sounds on the rear side of the oral cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the original sound is produced on the front side of the oral cavity, then the sound generation is simple, but the explosive sound cannot be articulated properly
Solution Approach 1:
The sound transmission path is segmented into multiple routes: a front side passage for general sounds and a rear side passage for explosive sounds. This segmentation allows the device to optimize sound transmission for different articulation needs without requiring complete structural redesign.
Solution Approach 2:
The patent introduces a rear side sound transmission passage as an intermediary structure that redirects original sounds to the rear side of the oral cavity. This intermediary passage enables explosive sound articulation without directly modifying the diaphragm or sound source.
2Adaptability or versatility
If the mounting body is fixed in position, then the device structure is simple, but the sound output position cannot be adjusted for different users
Solution Approach 1:
The mounting body is designed with movable characteristics, allowing it to adjust its position within the oral cavity. This dynamic adjustment capability enables the device to adapt to different user anatomies and optimal sound transmission positions without requiring multiple fixed-position devices.
Solution Approach 2:
The mounting body serves multiple functions: it anchors the diaphragm, provides adjustable positioning, and facilitates both front side and rear side sound transmission. This multi-functionality reduces the need for separate adjustment mechanisms while maintaining adaptability.
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 effective articulation of explosive sounds and consonants by blocking original sounds on the rear side, enhancing vocalization capabilities for individuals with larynx issues or tracheal incisions.
Implementation Method 1
a diaphragm that is provided at the facing portion and that is capable of outputting a sound recorded by a device having a recording function, as an original sound
Implementation Method 2
a passage that is provided at the facing portion and that is configured to transmit the original sound output from the diaphragm to a rear side of the oral cavity
