[Legebla ankaŭ en Esperanto]

I made this as a sort of experiment. Basically it’s an amplifier for an ipod or smartphone, but I also added two sockets for pens/pencils and two shallow wells for paper clips, coins, rubber bands, guitar picks, etc.

My wife liked it, so I gave it to her for an additional Christmas present. She took it to school and her kids use it to listen to the songs they have to choreograph for the show choir. In short, it’s a hit.

I made it from scraps of pine and oak. I finished it with spray lacquer.

[Fun Fact] The Esperanto word (in this case) for amplifier is: plilaŭtigilo.

I like your implementation as a desk accessory.

Thanks! Yours looks very cool. I have an idea for another one, but it’s not high on my priority list.

Looks great and the horn design should give some great projection! How is the bass response?

No idea. High fidelity it is not, but it is louder.

I just added the mandatory glue-up photo. I forgot that I had it.

Simple, elegant design, that works as intended—what else can you ask for? Oh, how about a DT3?!

Great idea. I’ve just made a music box, in which I’ve also tried to amplify the sound with out electrics. Essential it has 4 four guitar sound board timbers coupled to the movement to resonate/amplify its vibrations. Plus one of the sound boards has a dobro guitar resonator cone coupled to the movement. I’ll get round to posting it sometime. Amazing what you can do with out electrics – well done.

Turned out great, Dave! The opening, for the phone/player, looks a bit wider than the instrument. Will it fit other sized units? Is that a dowel underneath? To elevate the unit up from the floor? I like the raised back, does it provide support? Congratulations on the DT3 and another wife/student approved design! Thanks for sharing.

The opening MAY fit other units. One of the great hurdles in this project was the discussion of the hole size. It’s why this unit ended up in the hands of my wife. Originally I was to make 3 for family members. Everyone’s phone/device is potentially a different size with cases and all being non-standard.

I cut a small cradle shaped piece to support the player, more to keep it from tilting too much and to raise it up a bit.

The back piece basically just closes off the sound chamber, but I felt it looked better with a raised lip, an aesthetic choice.
