TV Speaker Horn For Vizio TV

thingiverse

So while I like my big living room TV, one of the trade-offs made is that the speakers are mounted pointing downward. Speakers were definitely an afterthought as it was assumed one would use a receiver. We definitely do, but for times when I'm not watching something that requires amazing audio, I wanted to save power (and avoid throwing extra heat in the house on hot summer days) by using the TV speakers. Well since the speakers are facing our entertainment stand instead of facing outwards, the audio is tinny, muffled, and requires turning the TV up louder than one should have to. To fix this issue, I built a simple stand to try to better reflect the audio forward. It's not scientifically designed but it works as a good first pass. The dimensions are for my Vizio 65" which has a speaker grille that is around 38x108 mm with a stand that's around 63mm in height. This thing was made with Tinkercad and can be edited online at https://www.tinkercad.com/things/75Gt0YVMUry. This was my first silly part to share, I hope you found it useful but feel free to improve it if you want. To print this design, use the following settings: Printer Brand - Wanhao, Printer - Wanhao Duplicator i3 V2, Rafts - Doesn't Matter, Supports - No, Resolution - .3mm. Notes: You shouldn't need supports, although the curve on the back end might not look amazing. One could add more support back there but I opted not to because no one sees it and the curve where the sound bounces off looked fine. A top was originally planned but that turned out to be a bridging nightmare so I opted to just print it as is for now. It might work better with a top, but it worked well enough without one.
