Micro-speakers for pi 3 and pi zero

[s710]

I want to resemble the snips maker kits (https://www.seeedstudio.com/snips.html), and thus bought a raspberry pi 3 and a pi zero. I also got 2 microphones, now whats missing is the speakers.

For the pi zero, I will attach a ReSpeaker 2-Mics Pi HAT to which I can connect a speaker (as snips is doing in the maker kits). This is by 3.5mm jack or JST. So I bought those: https://www.amazon.de/dp/B07FT9CFY4/ref ... 01_TE_item
This is going to work, right?

And since the above is 2 separate speakers already, how would I be able to connect the other speaker to the raspberry pi 3? for the pi3, unlike the zero, I got a different microphone (via USB), so I dont have a JST port. Could I just cut the cables and connect them manually to the GPIO or something? I am however totally unfamiliar with electronics, so I would know how to wire this up correctly.

To summarize:
I have 2 speakers: https://www.amazon.de/dp/B07FT9CFY4/ref ... 01_TE_item

I bought pi zero + ReSpeaker 2-Mics Pi HAT = I can connect a speaker to the JST port directly

I bought a pi 3 = where/how shall I connect the other speaker?

The only suitable place is the 3.5mm AV jack. However the output power available there is low so the volume from those unamplified speakers might not meet your wishes.

Okay but the speakers I already purchased are going to work well with the pi zero and the ReSpeaker 2-Mics Pi HAT, right?

And what other option would I have for the pi 3, if the 3,5mm output is too low? (apart from the speakers not having 3,5mm connectors)

I dont want to play music, its just for text-to-speech feedback for a voice assistant.

This one is best answered at their forum / support pages... hurry there!
any further question regarding the use/ support for the board is better done there.....

Get another respeaker thingy for your RPi3B?

better get yourself prepared for some (serious, major) headaches when you do your project with that board...
below is an excerpt from their github page....

While the upstream wm8960 codec is not currently supported by current Pi kernel builds, upstream wm8960 has some bugs, we had fixed it. we must it build manually.

this is one big reason why I stay far far far away from wm8960 based boards....

anyway.....good luck with your endeavor..

Okay well i am not bound to use the seeedstudio microphones. I really just need a pi 3 and a zero both with a small speaker and a good microphone.

Since this will be a voice assistant, good microphone performance will be crucial. Ive had issues with other microphones in the past, so i decided to pick their recommended ones. For the pi3 ive got the mic array 2 which is connected via usb.

I have already asked on their forums for viable hardware to create voice assistants without much success. So if youve got any recommendation for good microphones dont be shy.

In general i dont mind compiling stuff and all that (im a Developer after all), as long as the result is working properly.
