Portable Phone Hearing Aid Toggle Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with hearing problems face challenges in effectively communicating using traditional mobile phones due to insufficient sound amplification, necessitating the integration of a hearing aid function into a portable device.
Innovation Solution
A portable phone equipped with a sound receiving unit and a sound source playback device, allowing users to switch to a hearing aid function via a toggle unit, which amplifies surrounding sounds and plays them through an earphone or wireless module, providing adjustable volume and noise filtering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional mobile phone is used, then basic communication functions (calls, messaging) are available, but sound amplification capability is insufficient for hearing-impaired individuals
Solution Approach 1:
The mobile phone is designed to perform both traditional communication functions and hearing aid functions through a single device. The sound receiving unit, sound source playback device, and toggle unit enable the phone to switch between normal communication mode and sound amplification mode, eliminating the need for separate hearing aid devices and reducing overall system complexity.
2Ease of operation
If a separate hearing aid device is used, then sound amplification function is provided, but the user must carry multiple devices (mobile phone and hearing aid)
Solution Approach 1:
The invention merges the hearing aid functionality into the mobile phone by integrating the sound receiving unit, sound source playback device, and control toggle into the existing phone structure. This combination allows users to carry only one device while achieving both communication and sound amplification needs, significantly improving ease of operation.
3Reliability
If sound amplification is added to mobile phone, then hearing ability is supplemented, but additional components (sound receiving unit, sound source playback device) are required
Solution Approach 1:
The mobile phone's existing components are utilized for dual purposes: the microphone serves as the sound receiving unit for both calls and hearing aid mode, the speaker or connected earphone serves as the sound source playback device. This approach provides reliable hearing support while minimizing additional hardware requirements.
Solution Approach 2:
The mobile phone uses its own built-in resources (microphone, speaker, battery, processor) to provide hearing aid functionality without requiring extensive external components. The toggle unit enables the phone to self-switch between communication mode and hearing aid mode, making the system self-sufficient.
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 individuals with hearing impairments to utilize a mobile phone for basic functions like calls and messaging while supplementing their hearing ability, offering a cost-effective and versatile solution for communication.
Implementation Method 1
a sound receiving unit installed in a portable phone to receive a sound in the surrounding within an appropriate range
Implementation Method 2
a sound source playback device to play the amplified sound
Data Source
AI summary
The present invention discloses a portable phone using a sound receiving unit installed in the portable phone to receive a sound in the surrounding within an appropriate range, and then using a sound source playback device to play a sound after being amplified, so that a person having a hearing problem can just carry a mobile phone to concurrently have the basic functions of the mobile phone and use the sound amplification function of the mobile phone to supplement the deficiency of the hearing ability when talking to or communicating with others. The portable phone can be toggled between the regular telephone function and the hearing aid function, and thus concurrently serving as a hearing aid to the people who have a hearing problem.
