Seeed Super Directional Speaker Kit
Solder To Get Your Speaker
The Seeed Super Directional Speaker Kit features an amplifier, a speaker, wave transmitters, and all the other parts you’ll need to build your own speaker. This kit is considered more advanced because it requires soldering many points to assemble. The resulting speaker will have sharp directivity achieved by using ultrasound. It sends sounds straight and has many wave transmitters. Seeed notes that wave transmitters have polarity and require you to arrange the positive symbols of the transmitter and the PCB. The inductor doesn’t have polarity, but the PCB has several holes so you can use different types of inductors.
