Spelling out the 'sound': With just a small screwdriver, assemble a truly listening wooden radio by hand in 30 minutes, allowing STEAM Education to see, touch, and hear it! Raw wood without paint, birch plywood, laser cutting without burrs, retaining natural wood fragrance. The packaging contains an "antenna length experiment card" and a "radio positioning map", which guide children to test signal strength by hand and learn about electromagnetic waves and resonance principles. Example of educational scenario: ① Understanding components: What do capacitors, inductors, and chips look like? ② Tracking signal: Why are there more radio stations near windows? ③ Creative design: Graffiti the shell with colored pens to create a personal exclusive channel.
