Sandy listens to Ray Comfort and Kirk Cameron (www.livingwaters.com) sharing the Gospel every Saturday morning on YouTube while she makes our salads for the week so I made a passive speaker for her iPhone (and for her birthday). Curly Maple, Gaboon Ebony, and Curly Redwood, French polish finish. The difference in sound is very obvious - it’s richer, more balanced, and a little louder.
Cold bending the Curly Redwood; I resawed to the point I needed and then soaked it in hot water. After three times and bending successfully more each time I cut the pieces I needed and then glued them together.
Fitting the curved deflector; the square is just a prop to hold the deflector in place for the photo.
The first episode of the current season of the Woodsmith Shop television show on PBS features a Smartphone Amplifier design, similar to David's project above. The smartphone amplifier was featured in the Season 13, Episode 1301 show.
Better than I thought it would, yes. And last night when I left band practice at church I called home. After we talked for a couple of minutes she asked if I could hear her ok and I could so I thought maybe she couldn't hear me (I was in the truck on Bluetooth). She had the phone in the passive speaker about 4' away from her. Normally I can tell when she's on speaker but I thought she was holding the phone because I could hear her so well. So it apparently works both ways - excellent!
