BPMP is a portable amplifier concept that you can easily carry on your back.

Music has different effects on different people, but the truth is it always has an effect. At the very least, it can arouse the interest of the listener or arouse admiration for the talented artist who fills the air with notes. Despite how influential music can be, many people, especially parents, will argue that it’s hard to make money from music unless you’ve established a major presence in the industry. However, there are people who make and perform music with pure passion, but it certainly doesn’t hurt to get a few types of donations in the process. Street musicians and performers are not an uncommon sight in any country, and many have the same problem when it comes to hauling heavy equipment. For example, amplifiers are necessary, but very inconvenient, but this design envisions hardware that can help make life easier for these “punks”.

We’ve come a long way from the big boxes known as amplifiers that can only be transported using a wheelbarrow. There are many portable solutions these days that can help musicians performing in public move from one spot to another more easily. Despite their significantly smaller size, these amps often come in bulky boxes that you clumsily carry with one hand and leave only with the other hand to carry everything else.

It would be more convenient if you could hang the amplifier on your back like a backpack, but its boxy design makes this nearly impossible if not painful. Fortunately, technology and manufacturing have reached a point where this is finally possible, at least in theory. So BPMP is a concept that tries to squeeze as much equipment into a package as you can comfortably wear on your back. Better still, it’s not something you’d be ashamed of being seen around.

Instead of the typical box design, the BPMP uses a flatter “squirrel” or square circle shape with one side slightly projecting outward. It is designed like a typical backpack, with the flat side, shoulder straps and soft fabric material that cushions your back a bit. If you don’t know any better, you might think this is one of the hard-shell backpacks gaining popularity in some circles.

The portable amp reimagining doesn’t stop there. For example, there is also an arm that swings down to be the adjustable stand of the amplifier. The top edge holds the buttons and sliders for controlling the audio equipment, just like you’d find in a regular amplifier.


There’s no denying that besides the BPMP being so portable, it looks so attractive that you wouldn’t believe it’s an amplifier. It’s also questionable whether you can squeeze that much audio gear and electronics to function as a proper amplifier, and that doesn’t guarantee that the sound output quality won’t be affected by this unconventional design. Still, it’s a street worth exploring, especially if its already captivating performances will attract more attention from buskers.
