i need a PCB that can do the following

1. Take an input of 5-36 V DC and run a steady stream of 5 V to charge a cellphone and tablet. The input to the PCB will be directly form a truck battery or alternator or cigarette lighter.

2. A mini Jack connection needs to plug into the headphone jack of the tablet or cellphone. That mini jack need to connect to 3 different identities :

2.1 Speaker. I need an outside speaker that will allow the user to boost the sound from the tablet.

2.2 A speaker that will allow the user better sound when speaking into the device while driving. Better sound collection than normal mic.

2.3 An external switch that can be connector anywhere that will allow the user to answer calls with the switch or stop play misc as what they do at this stage on headphones.

I believe that the jack will need to be a 3 band jack to allow all the functions.
