I'm looking for speaker without battery. I mean I need a speaker whose power can be supplied by raspberry pi zero w.
I think I can use USB 2.0 simple speaker. I can cut its usb cable and connect its 5V cable to Raspberry's 5V pin and its ground to ground. Is it possible?
Moreover, jack input is not available for pi zero w as you know. So, I will use HDMI to VGA's audio output as seen the below picture. I don't want to use bluetooth option.
