3D printing can be a powerful tool to improve upon objects we use every day<\/a>. For example, I purchased a DragonTouch X10 tablet and quickly realized the rear-facing speakers were difficult to hear while I was looking at the screen. Even at the highest volume setting, many YouTube or Netflix videos were barely audible.<\/p>\n

I also wanted the tablet to be easier to hold and to stand upright on its own. So I designed a combination tablet stand, handle, and amplifier for my new tablet.<\/p>\n

You do not necessarily need electronics to amplify sound. Acoustic amplifiers can direct sound waves and enhance volume solely due to their shape. Having seen some acoustic amplifiers for iPhones, I realized 3D printing could do the same for my tablet.<\/p>\n

I started by using digital calipers to measure the thickness of the DragonTouch X10, the dimensions of its speakers, and the distance between the speakers and the edges of the tablet. I created a 3D model in Fusion 360 first by sketching the speaker’s shape and creating an offset. Then I created a few planes at different angles, and a loft between each plane to make a funnel that would direct sound toward the front of the tablet. I also made sure the handle would have a friction-fit around the sides of the tablet.<\/p>\n

\"\"<\/p>\n

After adding the handles, Netflix and YouTube videos were loud and clear with volume to spare! Also, while having a few friends over, I was able to put on some music in the background.<\/p>\n

Originally, I created these handles for desktop 3D printing, but I remixed them to be 3D printed in Shapeways Strong & Flexible Plastic<\/a>.<\/p>\n

\"\"<\/p>\n

The nylon would have a nicer surface finish and sturdiness than the ones I made on a desktop 3D printer, but the handles would cost more than that of the tablet itself. If I had designed these parts for Strong & Flexible plastic from the start, I would have integrated thinner walls and nested the parts as close together as possible in order to keep cost down.<\/span><\/p>\n

If you\u2019re using a tablet or smartphone, creators around the globe have designed 3D printed acoustic amplifiers available from Shapeways. Find one that fits your device<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
