Question

Wireless Charging (to do with speakers)

May 15, 2018 12:04PM PDT

Hi im sorry if ive posted this on the wrong forum

For my project at school I chose to make a portable speaker which can charge wirelessly. I’ve done research towards wireless charging but there isn’t much on wireless charging speakers. Can someone help explain how to connect my wireless charging receiver to a li ion battery and how to also allow cable charging and suggest a li ion battery for it. Look at pictures of what I’ve done so far. Also I tried charging a iphone x with the transmiter but it doesnt work is this because of the voltage coming out of the battery or some other reason (it does work with the led diode).
Thanks for your time

Here's a thing.

To make such a project we assign such based on what was taught in the classes up to the project assignment.

If you skipped some chapters then go back over those chapters to fill in your knowledge base.
If you are still lost, then talk to the instructor.

A level

im from the UK and do A level design and ourproject which is 50% of my grade can be anything. we are only taught about material and methods for our written exam and then for our project we need to pick anything which does not exist or not many of in the world. so this is not a listen in class thing.

Then you went beyond your capabilities for the moment.

While I have ideas on this it would be unfair for me to tell you how to accomplish this.

If I did I would have to tell your instructor and help the rest of the class to be fair.

To gain this knowledge you do what the rest of the class does. Google, watch YouTubes or if allowed outsource the product design.

All you need to see of the charging of the battery succeeded is a Volt-meter. Then what happens with the energy in the battery (be it a phone, a speaker, a toothbrush or a lamp or whatever) is a totally other thing. Anything that runs on a standard battery giving 3V will run on a battery that was wirelessly charged and now gives 3V, provided the power it can output is the same.
