Multiroom speaker

thingiverse

Hello guys! I've designed a speaker with a WiFi module and DSP, which means you can play music directly from Spotify through WiFi. You can also set up one speaker in the kitchen and another in the living room, playing the same song or different ones. I conducted a frequency response test (check out the picture) and the results are impressive for a 3D printed speaker! With a DSP, you can fine-tune the sound to your liking. If you don't want to program it yourself, I can send you the file so you won't have to mess around with it. Here's what you need to buy: * Woofer: DAYTON AUDIO RS150-4 Reference Speaker Driver Woofer - 40W, 4 Ohm, 92dB, 48Hz - 4000Hz, Ø15cm * Tweeter: Dayton Audio ND25FN-4 1" Silk Dome Neodymium Tweeter Element * Amplifier and DSP: WONDOM AA-JA32172 JAB 3-50 Class D Stereo Amplifier Module with DSP - 2x50W * Programming board for DSP: WONDOM DB-DP11219 SigmaStudio Programmer Board for Sure DSP * Multiroom/WiFi module: UP2STREAM Receiver Module DLNA AirPlay WiFi Multiroom Analog and I2S * Miscellaneous: Some M3 bolts (6mm and 10mm), M5 threaded rod for the legs (just buy one meter), speaker fabric, two magnets (2x2mm cylinder) and two more (8x3mm cylinder) You can always change the hardware to your liking - you'll receive a STEP file so you can modify it as needed. Printed on an Ender 3, but this design works for any printer with a bed size of at least 220x185mm. Material-wise, ABS is a bit easier to finish. Support: no. Infill: the higher the better! I used 80% infill.
