Let's say that I want to build a mobile phone or a truly AIO (All-in-One) PC based on RPi. Is this possible? If yes, then, please, guide me through the audio issuse, as I am failing on this.
In my research I managed to cover:
- main unit -- RPi,
- control -- touch screen,
- video -- touch screen + camera,
- communication -- RJ45, Wi-Fi, GPRS, Bluetooth etc.,
- power -- micro USB cable, battery-based power or PoE HAT,
But I failed completely on:
- speakers and
because I found no solution that would allow me to connect these two directly to RPi (i.e. not via mini-jack or USB).
Since I am building (at least in theory) a mobile phone or all-in-one station then I am not satisfied by simply connecting some standalone speaker to mini-jack and some also standalone microphone to USB. I know that this is very simple.
I have contacted two local RPi stuff suppliers and both said the same: most likely possible, but never seen something like that and never heard about any parts that could be used within (i.e. mike and speaker as an electronic part, attached to RPi's mainboard).
I want to be able to 3D-print my very own case, put everything inside (including mike and speaker) and build "a box". I want to add an ear and a mouth to my RPi Is this possible at all?
