Paper Speaker Workshop for Children

The Paper Speaker Workshop for Children is a hands-on STEM session where participants build their own working speaker using simple materials while exploring how sound actually works.

Led by Clifford Prince, this workshop introduces children to the fundamentals of sound, vibration, and electromagnetism through direct making. Instead of only learning concepts, participants construct a functional paper speaker and test it in real time.

Children begin by understanding the key parts of a speaker — the cone, the coil, and the magnet. They then assemble their own device step by step, using paper, copper wire, and magnets to create a system that converts electrical signals into sound.

As the speaker starts working, participants see how vibrations create sound waves and how these are amplified through the cone. The process makes core physics concepts clear, practical, and easy to grasp.

This paper speaker workshop is designed to make science tangible. It helps children understand how everyday devices work by building one themselves.

What children do:

• Build a working paper speaker from scratch

• Assemble cone, coil, and magnet components

• Connect the speaker to an audio source

• Test and refine sound output

• Observe how vibrations create sound

What children learn:

• How speakers convert signals into sound

• Basics of sound waves and vibration

• Introduction to electromagnetism

• Role of materials in sound amplification

• Hands-on problem-solving and experimentation

Workshop format:

• Introduction to how speakers work

• Guided step-by-step building process

• Hands-on assembly and wiring

• Live testing and sound experimentation

• Reflection through observation

Materials used:

• Paper speaker template (cone)

• Copper wire (coil)

• Neodymium magnet

• Audio input module

• Basic assembly tools

Why this workshop matters:

• Turns physics into a buildable experience

• Makes abstract concepts visible and audible

• Builds confidence through hands-on making

• Connects classroom science to real-world devices
