System Architecture
The subsystems considered in this design are an external shell, an internal dampening unit with an integrated microphone, audio monitoring and playback electronics, and two straps that help attach the entire system to the user's face.
The Internal Dampening Unit (IDU) is attached to the external shell via a tongue-in-groove attachment mechanism, along with allowing for a connection of the integrated mic with the sound processing unit. The Internal Dampening unit snaps fit into the shell via this mechanism. Along with the IDU, the shell also houses the electronics which are attached to the shell by a fixed attachment method such as screws. The dual straps attach to the shell that carries the two subsystems and is adjustable to allow for maximum comfort for the user. These straps help attach and carry the entire system to the user's face.
Finally, the external shell houses a connection for the Internal Dampening Unit's integrated mic and helps carry the audio signal to the audio monitoring and playback electronics.
Using the Proposed Concept
To use the proposed concept, the user first installs the Internal Dampening Unit into the shell. While doing so, it slides into place the connections for audio signals to the processing electronics.
Next, the user brings the mask up to their face and then fastens the lower strap. Once the lower strap is fastened, the user then pulls the second strap over their head, securing the device. The user then connects their headphones to the device and turns it on. Once turned on, the device is ready to be sung into!
With the help of these electronics, the user is able to hear live feedback of their voice--also known as monitoring. When the record button is pressed, the device stores the voice input it recieves and has the capability to be played back by pressing the play button.
