I am working on a school project and I need to build working speakers, then complete full legal and detailed drawings of its inner workings and so forth. Thats the easy part. The hard part is finding a design that targets 3-7 year oldss. (No spongebob or gumby) they are prohibited because they are just boxes with speakers in them. If anyone has a cool idea please tell me. Thanks😀 I have cool designs but they are more for older people who are into modern art and design. Little kid characters are not my forte.😀
