Mini speaker

It uses high-quality 40mm speakers from a headset connected in series. As an amplifier, it employs a powerful 6W Board Pam8403, which is connected to a reliable Bluetooth receiver and powered by a 5v USB source. The sound quality is excellent, with a decent volume level that's perfect for watching videos in bed while enjoying good audio fidelity. The speaker can be adjusted to three different tilt positions: 0°, 25°, and 50°. The entire enclosure is fully 3D printed, requiring no screws whatsoever. At the hinge, a small piece of 1.75mm filament provides additional support. I've successfully printed two units, one for each side of my bed, and they work flawlessly in both channels.
