Hi @Marita36, welcome to our forum!

I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.

On the link below you can see where the second microphone is placed (number 4). This microphone is used when you record sound and when using the speaker phone feature.
