I use a ge910 module and would like to use a speaker to the moduler. I have a speaker with lower than 8 ohm. Is it nessesary to have an external amplifier to get it to work? I have tried to connect the speaker direct but I almost dont get any sound out of it.
less than 8Ohm impedance is not suggested.
But you have to ear the voice anyway.
Can you share with me soem more details, schematic and so on?
Have you verified the speaker i s working itself isn’t it?
The speaker is working I have verified that. I also got some sound with an earpice. I think my way to solve this is to use an external amplifier to drive my speaker.
