Evidence of Work:

The purpose of our reverse engineer project was to further understand how the different components of headphones function, through a thorough teardown of the object. Through the teardown we will record all parts through detailed sketches, including labels and personal commentary. We hope to learn specifically what parts are responsible for successfully producing sound. Once we fully understand how the headphones function, we will work to improve the headphones structure, creating a more functional product for human use. To complete this goal my team would go about conducting a full report on a pair of SONY headphones over the course of two weeks. In this report we included a purpose (stated above), a hypothesis, a full disassembly, anaylsis the elements: functional analysis, structurial analysis, material analysis, and manufacturing analysis, and a product design. Lastly we presented our findings to our classmates through a summmarized slide show, which can be found below with the report as well. This was a lot of work which we equal divided among our team to best utilize our personal skill sets. Sally being artistic took on sketches, Anthony and Diego tackled researchering, and I tackled the functionality and editing writing components.

Our final report in my humble opinion came out really well. Our analysis were all well written and even though we struggled with the manufacturing component we were able to figure out the solution in the end! Our presentation is shown below. We tried to limit as much writing as possible, but that was diffivult with all our information. Instead, we came up with a solution by bolding key words. This way when we presented it the audience could be drawn to the key points of our presentation. The main features of our project can defiently be seen in our sketches and multiple analysis's. Those held the most information and where what we highlighted through our presentation. For myself perosnallly I put a lot of time in the functional analysis, so that was my key part. That is where I further investigated how electrons shake through the cord, how polarity rate changes, how a diaphram is moved back and forth, and how sound waves are created and manipulated to create different sounds!

Our links for both the slide and presentation are seen below, as well as some of the sketches of our model, timeline, and redesign plans. Check it out!

Content:

Headphones: a pair of earphones joined by a band placed over the head, for listening to audio signals such as music or speech. Used throughout our whole project to try and discover specifically how they work and how they can be improved.

Conceptual Sketch: freehand sketches that are used by designers, such as engineers, as a quick and simple way to draw. Not intended to be accurate or definitive, just to get the general idea of an object/structure. I used this in my project to draw out the parts from the pair of headphones, along with labels and descriptions.

Exploded View: a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. I used this in my project to show how pieces came together in the headphones.

Flow Chart: a picture of the separate steps of a process in sequential order. Can be used to describe various processes, such as a manufacturing process, an administrative or service process, or a project plan. I used this in my project to further explain how the headphones function, by explaining where the energy goes and how it is converted into sound energy.

Electrons: a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. When looking at the functional analysis, electrons are used to transfer energy, change the polar magnetic field, which moves a diaphram and creates sound.

Diaphragm: the thin, semi-rigid membrane attached to the voice coil, which moves in a magnetic gap, vibrating the diaphragm, and producing sound. Looking at the functional analysis is what was moved to create the sound waves in the headphones.

Polarity: the orientation of poles within a magnet. The different electron levels chnaged the amount of energy with changed the amount of polarity which causes the diaphragm or unstable magnet to get pulled back and forth and produce sound.

Sound Waves: longitudinal waves that travel through a medium like air or water (amplitude, intensity, pitch,, frequency). What is used to create sound!!! The whole purpose of our porject was to undertsand what lead up to the production of sound and how sound is made.

External: belonging to or forming the outer surface or structure of something. During the structural anaysis we had to focus on external and interior parts. The external parts included: ear muff, strap adjuster, plastic covering, etc.

Internal: of or situated on the inside. During the structural anaysis we had to focus on external and interior parts. The internal parts included: the magnet, diaphragm, coil, plastic, foam, air vent.

Bluetooth: a standard for the short-range wireless interconnection of mobile phones, computers, and other electronic devices. Our whole redsign was based on adding a bluetooth speaker in both ears to allow the user more mobility!

Reflection

This project was defiantly out of my comfort zone and allowed me to explore a new area of interest! One thing I did really well on was communication with my team. Due to a brain injury, only being able to go to half days of school limited me to the amount of time I could be with my team. However I did not want that to slow down how much I could contribute. For example, I communicated with my team what days I could go to to make sure I was there when we presented. I also texted my team on the side to let them know what I would be getting done at home when I was not there. When I was in class something else I did well on was utilize my team. I wanted to help my team and make our project the best it could possibly be so I was working hard all period, utilizing every minute of the class. I think this really payed off because a lot of the time I was able to finish my own goals then work to help others on their own sections. This made it so each section of the report had multiple edits, multiple research methods behind it, and overall multiple opinions. Thus resulting in a well done report, full of knowledge and being well communicated.

Overall I did really well, but there is always room to improve! In the future I want to work on tackling topics deeper. Feedback we got on our report was to go even further in detail when researching. We have no limit of how long we can present so I want to research more and become an expert on what I am looking into. For example, I was researching how electrons move throw the cord of the wire, and pass on future electrons, and change polarity levels which pulls a diaphragm back and forth which makes sound. Even though I was an expert on the first part and thought it was super interesting, to an audience it was not enough. In the future I need to go into more detail about all the parts, and in that case more detail on how sound waves work. Something else I could do better is to never become doubtful when facing a problem. We could not find a certain part of our headphones for over a week and all of us as a team felt like giving up. However we did not and we ended up finding the part name, we should not have lost our hopes. In a team environment everyone should always stay positive and never lose hope and in the future I want to hold myself more accountable for that. If one person stays positive it can make a huge difference and I want to be that person!
