Student teams are challenged to create an energy-free speaker system for any hand-held device. In order to effectively complete the design challenge, students will explore the wave behaviors and transfer of energy in a sound wave. Students will also analyze the volume of the device and the speaker system as solid figures. Students will study the history of amplifiers previous to designing their speaker system and will prepare a report to justify each step of the engineering design process. Teams will propose their prototype to pineApple Inc. through a presentation of their choice. pineApple Inc. will award the contract to the team with the best overall design.
