Customer Requirements/Product Selection ■ Target market: – Our target market is elementary school aged children and elementary school teachers ■ Why we chose this product: – Interactive and fun way for children to learn – Improves upon current experiments teachers often use
Conceptual Design ■ Our conceptual design led us in the direction of a domed tube that allowed us to mount audio equipment to mount all hardware. This would be the mechanical components that vibrated whatever medium is placed inside. ■ It would be built to have sound vibrate a seal between the speaker and the liquid. This would be made out of a pliable material such as wax paper or a balloon. ■ Most of the exterior frame was to be made out of plastic and small amounts of metal. ■ The exterior will be painted with black chalkboard paint so that it can easily be modified by an instructor.
Actual Design ■ Our actual design led us in the direction of a domed tube that allowed us to mount audio equipment to mount all hardware just as in concept. ■ It differed from the concept where as instead of a pliable medium between the speaker and liquid, we 3D printed an extension of part of the speaker know as the tweeter. This allowed direct contact between the liquid and the speaker, increasing the ability to the device to vibrate the liquid. ■ Most of the exterior frame is made out of plastic and small amounts of metal. ■ The exterior is painted with black chalkboard paint, so that it can easily be modified by an instructor.
