Singing Assistance Mask for Mechanical Voice Volume Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing singing assistance masks do not allow for adjustment of the intensity of sound conducted through air, making it difficult for hearing-impaired individuals to hear their own voice and causing loud voices to overpower other sounds, thereby hindering effective singing practice.
Innovation Solution
A singing assistance mask with cheek contacting regions that include volume adjustment members to mechanically adjust the intensity of sound transmitted through air to the wearer's ears, allowing for personalized sound volume control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the mask transmits sound conducted through air to the wearer's ears, then the wearer can objectively monitor their voice, but hearing-impaired persons cannot hear their own voices and persons with loud voices cannot hear other sounds
Solution Approach 1:
The mask incorporates adjustable components that allow the sound transmission characteristics to be dynamically modified according to the wearer's needs. The cheek contacting regions can be repositioned or adjusted in configuration to change the amount of air-conducted sound reaching the ears, enabling adaptation across different voice intensities and hearing abilities.
Solution Approach 2:
The invention allows modification of physical parameters of the sound transmission path, such as the distance between the mouth and ears through adjustable cheek contacting regions, the cross-sectional area of sound passages, and the degree of sealing. These parameter changes enable control over sound intensity and quality to accommodate various voice levels and hearing conditions.
2Ease of manufacture
If the mask structure is simplified without volume adjustment members, then manufacturing is easier, but the intensity of sound transmitted to the ears cannot be adjusted
Solution Approach 1:
The mask is designed to enable users to adjust the sound volume themselves without requiring complex electronic components or professional assistance. The volume adjustment members are positioned and designed so that wearers can easily manipulate them during normal use to achieve their desired sound level.
Solution Approach 2:
The invention provides mechanical means for users to adjust key parameters of the sound transmission system, such as the opening area of sound passages or the positioning of cheek contacting regions. These adjustable parameters allow customization of sound intensity while maintaining a relatively simple overall structure that remains easy to manufacture.
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 hearing-impaired individuals to objectively monitor their voice and improve singing ability by adjusting sound volume mechanically without degrading sound quality, while allowing others to hear the voice directly.
Implementation Method 1
transmit a voice emitted from a mouth of a wearer to ears as sound conducted through air

AI summary
A singing assistance mask that transmits a voice emitted from the mouth of a wearer to the ears of the wearer as sound conducted through air may comprise a front mask body that covers the mouth of the wearer; and cheek contacting regions that extend in a front-to-back/back-to-front direction so as to be directed toward locations in vicinities of the ears at left and right sides of the front mask body, and may have formed at insides thereof concavities constituting sound passages. Cheek contacting regions may comprise volume adjustment members for mechanically adjusting volume of the sound conducted through air that is transmitted to the ears. Ear proximate notched holes may be formed at back ends of cheek contacting regions. Volume adjustment members may adjust degrees to which ear proximate notched holes are made to be open.
