Halo Speaker

14 Weeks | Fall 2022 | Prototyping & Creating | Individual Project

Create a fully functional speaker out of existing components.

The Challenge

In this project, I was to use existing components of an existing speaker as constraints to design and build into my design. There was a lot of trial and error involved to get the best possible arrangements of components into my design.

Prototype 1 Goals

Understanding the Components

With the goal to understand how components interact together in an electronic I built a very simple initial speaker.

Understanding how the original speaker works.

Learning how to seal components for better sound quality.

Learning and experimenting on the machines in the shop

Component Analysis

I investigated each component's role and learned whether they needed to be placed near other components or isolated for the best sound quality.

Making Prototype 1

Takeaways

  • Battery needs space, it cannot be compressed.

  • Speaker heads (drivers) should be sealed to have better sound quality.

  • 2 or more screws to prevent movement.

  • Always leave a tolerance (even more for laser cut pieces since it leaves an angle).

Notes on Designing the Springboard

Rough progress on how the springboard was refined.

Conceptualizing My Design

Visual models

I created three variations of the aesthetic design and constrained it so that I could start focusing on the development of the interior.

Ideating the Interior

I made temporary component housings to start arranging them into the aesthetic design, and look for things such as thicknesses that I might have forgot to consider.

  • Variation 1

    Why I decided to change it

    I found it hard to see how I could adequately seal the radiator with the drivers.

    Pros

    • Charge port is placed near connector

    Cons

    • Circuit board is on top of the radiator

    • No way to separate for seal

    • Battery not protected

  • Variation 2

    Why I decided to change it

    I noticed that plugging in the drivers and charge port will be very difficult to achieve.

    Pros

    • Components fit

    Cons

    • Battery is more secure

    • Still unable to seal properly

    • Only fits one radiator

  • Variation 3

    Why I decided to change it

    In order to plug in the battery I had to twist the cable too much. As well as it was too tight for some components.

    Pros

    • Can fit two radiators

    • Radiators and drivers are well sealed

    Cons

    • No space for charge port

    • Attaching battery to seal might be complicated

  • Variation 4

    Why I decided to change it

    The vacuum formed form takes too much space to seal, maybe if I change the battery position?

    Pros

    • Placing of the buttons works well

    • Drivers are sealed with radiator

    Cons

    • Chargeport is tilted

    • Vacuum form takes up too much space

  • Variation 5

    Why I decided to change it

    Even after changing the battery's position, the vacuum-formed piece was still taking up too much space.

    Pros

    • More space to seal vacuum form

    Cons

    • Placing battery on top increases thickness of speaker

    • Doesn't solve vacuum form problem

  • Variation 6

    Why I decided to stick with it

    Instead of sealing the drivers with a separate piece, I thought I could seal them using the piece that holds the outer ring together. Every piece needs a functional purpose.

    Pros

    • Seal is provided by outer ring

    • Radiator is placed on the back of the speaker

    Cons

    • Unsure of battery placement

    • All of the buttons have to be tailored to form

The Finalists

Explaining my process on how I went from variation 5 to 6.

Semi-Final Variation

Explanation

There was no space for piece 8 and the seal. I created piece 18 to hold the Halo together, but this made the Halo purely aesthetic, which wasn't my goal.

Final Variation

Explanation

Piece 15 solves the problem, it gives the Halo a function, so it can hold the seal while also giving it the suspended feeling without the need of screws and extra pieces.

Final Variation

Take a look at the final speaker from the inside! The orthographic drawings were especially useful for the construction of the model, they served as reference and for double checking measurements.

How it Assembles

Making the Halo

Takeaways

Initially, I was going to take a piece of walnut wood and turn it just like that, but a friend suggested I look into how drums are made. He said it would save me money on wood and time. I got to work, did the math, and took on the challenge! Here is how I did it.

Next Steps & Takeaways

Have fun and enjoy the process

This project was a lot about learning how things work together. If I learned one thing, it is that things are almost always not going to go your way, so it's better to embrace that, enjoy it, and keep trying to make the best design you could have done with the amount of time and knowledge you had at that moment.
