How To Make Wooden Bluetooth Speakers | DIY Project

How to Make a Folding Cedar Lawn Chair

Let’s be honest. We can’t simply put down our cell phones long enough to plug them into a headphone or a speaker. Bluetooth to the rescue! With a love of all things DIY, with having this project I built my own set and thought I should share the experience of this DIY for anyone else who is looking to do the same.

Building your own portable Bluetooth speakers has got to be one of the most entertaining, rewarding, straightforward, easy, and cost-effective DIY projects I have come across. I am absolutely shocked that it has not had a larger presence in the community... well, until now of course.

What’s great about Bluetooth speaker is the fact it does not even really look DIY, which is surprising and awesome at the same time because it’s built up of wooden cover. Beyond that, you will just need a Bluetooth module, speakers, various cables, a small amp, and a battery. This is a pretty easy project overall.

Bluetooth speakers have exploded in popularity, and are the easiest way to play music on your smartphone. The problem is the speakers are usually a bit smaller and the sound doesn't quite fill a room.

The composition needed to build a Bluetooth speaker is simple, you need a speaker (or two!), a Bluetooth module, resistor, and power supply or battery. The material and supplies you choose to use for building the casing or body of your Bluetooth speakers are up to you.

So, if you have got access to some necessary components for Bluetooth speakers and tools like a table saw, a handsaw, a jigsaw, a drill, a measuring tape, some wood glue, clamps, and a place to make some sawdust, then you have got a golden chance to build your own Bluetooth speakers, as I did.

In this article, we will cover the entire process of DIY Bluetooth speakers, from materials, tools, sourcing components, to tips and tricks, to exotic and inspiring finishing options.

As like other woodworking projects, this project will also need some basic woodworking tools and materials along with some electronic components for your Bluetooth speaker. The list of the materials and tools needed is given below.

So, with these tools and components, you can build an audio Bluetooth amplifier speaker easily. This project doesn’t need any professional woodworking knowledge, you can build this DIY with having basic woodworking knowledge, knowing the tactics to use tools and some basics to connect Bluetooth amplifier with speaker. Let’s start the project with having some step by step instructions given below.

Step 1: Collecting Scraps and Other Materials


The first thing in any woodworking project is to collect all the material of the project at your working place. Same for this project, you need to take some scraps, wood boards, or pallets to your working place.

The speaker I had, I got it by walking into my local car stereo store and the best thing was I get that free of cost, which was very kind. You can buy it from the market or from online sites. I have had a piece of tree pallet that I got from my pallet store. You can take some wooden boards that are little larger than the area of your speaker. Take those pallets, boards and cut them off to the desired measurement. As I did, I have used a miter saw and cut that pallet wood to give it a shape of a board and realize it is quite enough to work with the speaker I had.

After that, I have taken some more boards to cut and decided to use cherry board instead for the front and back face now. This will give some elegant look to the speaker case. You can take some wood boards instead of using cherry, I used them because I already have had those.

Now to contrast the cherry I have used beautiful walnut for the sides. So, I was just planning that out to match the grain continuously.

Pro Tips

  • If you don’t have your own electronic components, then while buying these components, you should make sure that all the components are working properly.
  • If you have taken some pallets, you have to do sanding of it before starting the project. It will give a shiny look to your case and also you can go on cleanly with your project.
  • If you are also taking some cherry boards, make sure that your cherry boards are not damaged, because it will create a problem when you cut them out for a case.

Step 2: Cutting Scraps and Cherry


In the second step, you have to cut cherry or wooden boards to the desired measurement. Measurements of all the pieces to be cut, given below.

I had the cherry board, so I have cut pieces from it.

Measurements:

2 - Cherry 10¼ x 5 inches

2 – Side pieces 6¼ x 5 inches each

2 – top and bottom boards 11 x 5 inches each

Cut these boards by using a table saw or circular saw. As I ripped the board on the table saw to cut it into the desired size.

Once you have made all these pieces, it's time to move forward to the third step.

Pro Tips

  • Be careful while cutting the boards. Here, one thing you should remember that never use gloves when you are using a table saw in any woodworking project. And also you should make sure that you are wearing short sleeves, if not then make your sleeves folded up.
  • Hold the board on the table with clamps, while cutting on the table saw.
  • Before cutting, check twice the measurement of all the boards if they are same.

Step 3: Routing and Mitered Cutting


Now to fit the back and front boards on these top and bottom pieces, you need to do routing of the boards. As I did it by using a router and make two routed lines on each walnut (top and bottom boards).

And it's a lot easier to add those routing lines before cutting the wood boards.

Now it was the time of mitered cutting. It’s the most interesting work I got, in any woodworking project. They are kind of tricky cut we should make. Make sure that you have mitered each board at the same angle. Otherwise, it will make the problem for you while making joints of the boards.

Pro Tips

  • Use the router table for your router. Router tables are great for cutting your moldings. Using a router table is much easier as well as faster than using a router alone. While using a router table, you don’t have to clamp the board.
  • Make sure that your bits are sharp, smooth, and clean.
  • Make multiple lights pass rather than one heavy cut.
  • If using handheld router, make sure that the workpiece won’t shift.

Step 4: Preparing Front and Back Sides


After metering and routing, I have had placed my speaker on the board which I decided to place on the front of the case. Follow this step and mark the area of your speaker on the board by using a wood pencil.

Now, drill four holes on the four opposite sides of the marked circle on the board by using a drill bit. This will help you to pass the coping saw from the holes and cut out that marked circle. You can also use a jig saw instead of the one I used.

Once you have done it, Use a fence and to make smooth the inner side of the board that you cut for fixing your speaker.

Now take an MDF board piece and make a circle of your speaker size by placing the speaker on it. Cut it from the markings, and make some random sized holes in it. Now you have an MDF piece like the one shown in the image below. You can also put magnet pieces in its corner holes.

Take a piece of speaker fabric from any fabric store and cut it to the size of the MDF board. Attach this fabric to the MDF board by using glue.

It still needs two more holes on front board for a switch and LED light as well as in the back board for the power cord.

Pro Tips

  • While making the cut with the help of Jigsaw, you have to firmly hold down the saw to keep the blade from chattering. The two combined forces, downward force and vibration of the jigsaw is tough on the work surface.
  • While making the holes with a drill, drop the drill bit slowly on the board surface, otherwise, it can harm your board.
  • All cuts and holes should be done with respect to the measurement of the components, not more than that.

Step 5: Building Up the Case


Put all the boards in a sequence in which they all will join up together. Put some glue in the routed lines of the boards as well as on the mitered sides of all boards.

Place all the boards (leaving top board) in a line on masking tape and joint them up. Leaving the top board will help you to float the front and back in these boards freely.

Now put the top board on the case and it’s done. You have a box for your Bluetooth amplifier speakers. Secure the boards by using masking tape and clamps for some time and let the glue to be dried.

Now, you have to sand the speaker box by using a sander. It will make the surface of the box pretty smooth.

To get the speakers off the ground, I could have some small squares of cherry and attach them to the bottom of the box of each corner on desired distance from the sides.

I have attached these small boxes by using wood glue.

Now, it’s time to give a finishing touch to your elegant looking speaker box.

Pro Tips

  • Always use white glue in woodworking, because it is easy to clean and dries clear. White glue is also suitable for using on light weighted materials such as paper, leather, and some types of wood.
  • While gluing the boards, wet both wood surfaces with glue which are to get joint.
  • Using of masking tape instead of clamping makes easier for everyone because maybe someone can’t be able to arrange clamps.

Step 6: Finishing the Box and Setting up Electronics


After finishing the box building, you can use stain to make shine your box. But I have used to do three coats of shellac and once that was dry, I have added some of my tang oil, wax polish with steel wool in that super smooth field.

Now, it’s time to connect all the electronics we have for the Bluetooth speaker. The phenomenon of connecting them is pretty simple. The power coming into the switch which splits off, one wire goes to the blue LED connected to a resistor, and the other wire goes directly to the amplifier, then the amplifier, of course, connects to the speaker. This connecting method is also shown in the diagram below.

Secure every component in its place in the box by using hard power glue, but use screws to secure the speaker on the front.

Now, it’s time to check your Bluetooth speaker if it is working fine or not. In my case, it was working superbly fine. You can also control the volume of the speaker with it.

Pro Tips

  • Make the connections tightly and you can cover them up with tape. If the connections are loose, it can get heated up. And always use wire-stripping tool while removing the insulation of the wire.
  • Don’t glue the cover up of the speaker, place it on the magnets.
  • Make sure you have secured the switch in its place tightly.
