TetrahedronSpeaker

thingiverse

I had an old Sony Vaio laptop collecting dust, so I decided to breathe new life into it by repurposing some of its parts. I crafted a speaker housing for the two tiny speakers, each with a diameter of 36mm. Using clear two-component glue, I attached the spacer rings and grills to the speakers, then assembled these two modules into the frame. The spacers ensure that the delicate membranes don't touch the grills. My goal was to use this speaker on my raspberry pi, so I needed a small amplifier board (PAM8403) to amplify the audio signal and an old headphone plug soldered to it. I connected the speakers to the output of the board and two wires for the power supply. Since the amplifier requires just 5V, I linked these two wires directly to the GPIO pins of the pi (5V and GND). The base is secured to the frame with one screw (Ø 3mm) from the old laptop. There are three faces where you can attach some rubber feet (Ø 8mm) under the base. The amplifier board I used: https://www.ebay.de/itm/252797545663
