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.
