3D Models for Phone Speaker Amplifiers and Stands

This collection gathers 3D models for turning a phone into a more directed sound source. It covers passive amplifiers, stands with acoustic channels, and small boombox-style enclosures. You can print these designs on a 3D printer and adjust the scale or openings to the phone you have. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«3D Models for Phone Speaker Amplifiers and Stands»

The models fall into a few practical groups. Passive amplifiers use a horn or channel to guide sound from the phone speaker. Stands with speaker effect combine a cradle with an acoustic path. Boombox-style designs enclose the phone and may add a larger opening or multiple channels. Novelty holders shaped like characters or objects also appear.

When choosing a model, check the phone placement and speaker location. Bottom-speaker phones need a different opening than phones with rear or side speakers. Look at the number of parts, whether assembly is required, and whether supports are needed. The author's page often lists material, layer height, and photos of real prints.

To refine a search, try terms such as passive speaker, acoustic amplifier, phone stand, sound dock, and horn speaker. Related topics include phone holders, desk organizers, and small speaker enclosures. Adding the phone model or speaker position can narrow results, but avoid relying on one phrase alone.

FAQ

よくある質問

What is a passive phone speaker?
It is a printed shape that channels sound from the phone's built-in speaker without electronics. The shape often uses a horn, tube, or reflective surface to direct the sound.
Do these models need supports?
It depends on the geometry. Check the author's page and the orientation shown in the files; some designs print in place, while others may need supports for overhangs.
Which material works for phone speaker models?
PLA and PETG are common choices. Rigid materials can help the enclosure keep its shape, while the author's settings and photos give a clearer idea of the result.
How can I make the sound direction better?
Align the opening with the phone speaker and keep the channel smooth. You can also test different scales or add a simple reflector, but the result depends on the phone and the printed geometry.
