Dayton Audio TT25 shaker mount for Wupro Gallery screen

Laser speckle can be annoying with laser projectors if you're sensitive to it.
Following the discussion started here: https://www.avsforum.com/threads/laser-speckle-reduction-via-vibration-example.3345388/, I adapted the idea for my own setup.

The idea is to transmit gentle low-frequency vibrations to the screen. Each tiny movement rearranges the speckle pattern, and because it changes faster than your eyes can follow, the speckle blurs into a smooth image and becomes much harder to notice.

For this setup to work you'll need the following:

1- 2x Dayton Audio tactile transducer TT25-8 (https://www.daytonaudio.com/product/1104/tt25-8-puck-tactile-transducer-mini-bass-shaker)

2- An amplifier that can play mp3 from an SD or USB card (I used a cheap AK45 found on amazon, it's great for the price and has its own power supply https://amzn.asia/d/06vvUBd5)
You'll find 3 models attached:

• a TT25 holder for fixing it vertically to a flat surface.

• a TT25 holder to attach to a WUPRO Gallery fixed screen

• A drill guide to drill three holes in the screen aluminium frame

I have a few projector screens and those two will work for the majority of them, not just Wupro.

Per holder (both versions): attaching the TT25- 6 × M3 heat-set brass inserts, M3 × 6 mm long × 5 mm OD (the "M3x6x5" size)
- 6 × M3 × 8 mm screws, through the TT25's tab mounting holes. The brass centre hole in each tab holds the TT25 together; don't use it for mounting.

Per rail mount (Wupro gallery version): attaching it to the frame- 3 × M4 heat-set brass inserts, M4 × 8 mm long × 6 mm OD (M4 × 6 × 6 also fits)
- 3 × M4 screws: M4 × 10 or × 12 screws
- 3 × M4 washers
- Loctite 243 (medium strength, removable). Not 263, which is permanent.

Flat-surface version instead: strong double-sided tape (Gorilla black worked; avoid thick foam tape) or screws through the base.

Tools and consumables- 4.5 mm drill bit plus the printed drill jig, one fresh jig per set of holes (as they get easily damaged when drilling)
- Soldering iron with an insert tip
- Something to keep swarf off the fabric while drilling, best to use a vacuum cleaner while drilling.
- Optional: felt or tape where the frame's aluminium parts touch, to stop rattles

Totals for two units (rail version): 12 × M3 inserts, 12 × M3 × 8 screws, 6 × M4 inserts, 6 × M4 screws, 6 × M4 washers.
