Download Phono Horn

Phono-Horn. A paper sound dock for your smart phone! Play your phone through the Phono Horn and the sound output is richer and clearer with improved bass response. There are two base templates included, one for iPhone 4S and one for Samsung Galaxy S2 and S4. It should be easy to adapt the kit to suit most phones. It is simply a matter of ensuring that the loudspeaker on the phone is positioned over the horn inlet hole. This model is free for everyone to download and make. If you have enjoyed making it I hope you will consider making a donation at the button. Thank you!

(I have also adding this project to the Instructables website)


The model works well printed onto coloured card. (230 micron / 67lb) I used a selection of colours from these cards I bought from a local stationer.

Print out the horn parts sheet (page two) twice on complementary colours. Print out page three on another colour and then either page four or five depending on whether you are making the iPhone or Galaxy version. The final page is the project label and should be printed onto white paper.

Score along all the dotted and dashed lines before carefully cutting out the parts.


Fold round and glue down the wide ends of the horn pieces to make triangular tubes. These keep the end of the horn rigid.


Glue together two of the horn pieces with tabs on the end. Line up the parts as accurately as possible.


Glue the next two pieces into place this time using two pieces without tabs.


Alternate two with tabs the two without for the remaining horn pieces.


Roll round and glue the end into a circle.


Work your way along the horn gluing one row at a time...


...right up to the end of the horn.


Glue together the four sided end pipe.


Glue the end pipe to the horn.


iPhone 4S Version.

Assemble the two main base pieces as shown.


Glue together the two cross pieces.


Fold round and glue up the triangular shaped lower front.


Fold up and glue the horn holder.


Fold the end of the horn holder into place and glue it down. Notice the small hole. this will line up with the loudspeaker on the iphone.


Glue the five parts of the base together. Keep everything as square as possible so that the base sits properly on a flat surface.


Glue the horn holder to the base as shown.


Complete the model by fitting the horn. there is no need to glue it into place. Place your iPhone on the stand with the loudspeaker lined up with the hole in the horn holder and be amazed at the incredible sound quality!


Samsung Galaxy Version.

Assemble the two main base parts as shown with the tabs folding in as shown.


Fold up and glue together the horn holder. The picture shows the version with the Galaxy S4 hole cut out.


Assemble the two back cross pieces.


Fit the horn holder into place using the grey areas for alignment.


Glue the two back cross pieces into place. Make sure that everything is square so that the base sits properly on a flat surface.


Fold up and glue together the base front.


Glue the base front into place as shown.


Complete the model by fitting the horn. There is no need to glue it into place. Place your Galaxy on the stand with the loudspeaker lined up with the hole in the horn holder and be amazed at the incredible sound quality!

Awesome as always Rob! Will you still give a chance to the paper record player (or gramophone, however you call it) idea? That'd be awesome!

Well if you are into doing custom jobs, then how about the Nexus 7 please, in horizontal slope mode.

Oh and the speaker slot is on the back at the right hand end.
