An active-learning experience has been designed to introduce high school students to engineering technology and product development. In a three-hour program, students are guided through the product development cycle as they construct an amplifier circuit and speaker cone assembly. This multidisciplinary project touches on electrical, mechanical, and manufacturing roles in the development of a product.

The project begins with an introduction to the principles of soundwaves and amplification. Electronic design of the speaker includes discussion of component selection, explaining the need for each element of the design. Design of the mechanical bobbin, cantilevered spring arm, and circuit board housing allows for discussion of requirements that arise from structural needs along with design for manufacturability (DFM) and design for assembly (DFA) considerations. Throughout the discussion, students are guided though the assembly process which involves soldering electronic components to a prefabricated printed circuit board (PCB), winding wire around a 3D printed bobbin, and fastening the components to a wooden base. Upon completion of the assembly, students are able to play music from their phones and electronic devices through the amplified speaker assembly.

This speaker project has been utilized through multiple sessions of Women in Engineering (WIE) summer camps involving high school female students. Surveys of students following the exercise indicate a high level of satisfaction with the concepts and product. Students walk away with a self-made product, and more importantly, a lasting impression of the accessibility of product development and engineering.
