Infinity BassPack 1.0

Hello Guys... Today I'm going to show my latest invention in mu one of my favorite categories... Sound and Light are my favorite topic of interest. For many years I have collected many headphones and earphones along with a few good quality big sound systems in my house. But they all lack in one sector... The bass of them is not that exciting and we only can hear the bass notes... So I wanted to make something that will help us to feel the Beats and the Bass notes in a more interactive way,

Here I am presenting my latest invention. The "Infinity BassPack". This product helps us to feel the Beat notes and all the low-frequency vibrations in our bodies. This product or this project is open source and can be altered as needed... The Theoretical range of working of this BassPack is 20Hz to 300Hz... I'm not an electrical engineer or a sound engineer ...I have tried my best to make this project as much perfect as the first try... and I'm satisfied with my results. The bass quality is well punchy and the Project works as intended... In the process of making this project I messed up some parts sometimes but I recorrected them.

This Infinity BassPack has its own batteries so it's wireless and the audio connections can be made using either my built-in Bluetooth connectivity or with the Wired method... I also installed a port for a 3.5 mm Aux outfit for our Wired earphones or the headphones...

So Without wasting any more time. Let's get started on the project. ^-^.

For this project we will need these main items...👇

• My 3d files + templates... Or your own files
• 3d printer and filament
• Filler compound & spray paints...
• Bag making supplies and nilon fabric
• Fake leather (optional)
• Straps and buckles

Electrical components 👇

• 4 - 180163 Lipo Batteries..
• 10 amp 3S BMS board...
• 40 watt 3 inch Subwoofer
• 1 step down converter
• 1 step up converter(optional)
• Pam8610 /TPA3110 audio amplifier board (15 watt dual channel) / mono channel TPA3110 30w amplifier
• Bluetooth audio receiver (I used bluetooth 3.0. You can use higher)
• Lipo battery charger board TP4056
• 6 pin latching switch
• 5 pin aux female connector (2 piece)
• 12 volt barrel connector female
• 26 gauge wires

Tools and other items for this project 👇

• 3d printer
• Soldring iron + flux + solder Wire
• Heatshrink tube
• Glue gun with glue sticks
• Sanding paper
• Some random tools and supplies...

If you want to recreate my version of this project as it is.. Then just print the 3d files with normal ABS or PLA filaments and the templates on the A4 sheets...

Files 👇

*I need some time to finalize the parts and the templates... There are some minor upgrades which I want to implement on the final files... So pls wait for some time.... I will upload the files very soon....

For this project it's mandatory to gather all the parts before hand.. And if you want to recreate the same model like me.. Then try to find the exact same components which are intended to fin in their allocated slotes...

I will upload a detailed parts list very soon...

I have made the files in 2 pieces for easier assembly...

Use some epoxy glue or any other type of glue... And then simply use that for fixing the parts together...

When the parts are joined together.. Now take your sand paper and give a light or hard sand depending on your piece and smooth out the joints and the whole print body...

Now apply Crack filler or any other bondo type fillers and apply all over the piece...

Let the piece dry for atleast 12 hours depending on your filler type...

After the filler has been set... Take a piece of sandpaper and smooth out the surface...

Spray paint the whole thing with your desired paint and let it dry for some time...

Use 2 coats if necessary

For making the Low pass filter... Gather these parts 👇

Now on a piece of zero board /proof board... Solder them accordin to my given schematic diagram..

I have tuned this low pass filter for both the amplifier board and the final output can be adjusted by the inbuilt potentiometer...

Assemble all the electrical parts and wire them up as I showd in the scemetic diagram...

If there is any problem... It should be fixed right now...

The output from the speaker should be only the Low frequencies and it should be clear and powerful...

Assemble all the parts in the enclosure and wire them finally with the help of my given diagram...

There are 2 potentiometer caps and a switch cap... Don't forget to add them....

Using hot glue... Attach all the parts inside the enclosure and secure them.... Use plenty of glue so nothing comes lose later....

Using my templates printed on a a4 sheet.... Trace out pieces from foam sheets and the fake leather and the Bag making material.... If I'm not wrong then that is nylon fabric...

Now... Again using hot glue... Fix the parts as shown in the picture.. And make sure to fix the parts firemely...

You can also give stitches on the joints with a sewing machine.. But my domestic machine isn't that powerful for this job.. So I did this part by hand...

Add the straps and all the straps needed in their intended places... Take a look on a existing backpack for understanding the locations and the shape of the handle...

Here I used some hot glue to create some solid piece which will connect the speaker diafram with the backplate... And also used some hot glue to attach the backplate with the main body.... I skipped the previously designed smaller piece of the backplate because that is somehow reducing the overall vibration....

So this is the build process of this Bass Pack v1.... And I'm looking forward for making a 2nd version of this project with more powerful vibration actuators and more prominent design and bulild quality... For that.. I just need all of your supports and suggestions....

Pls let me in the comment section your thoughts and responses... Untill then stay creative and u will see you next time....
