مُبدِّل الصوت الذاتي (افعله بنفسك)

Explore the science of sound by building a real working voice recorder and changer with the SpyX DIY Voice Disguiser STEM Building Kit. Children connect the electronic modules, complete the circuit and create a reusable spy gadget capable of recording and disguising short messages.

Follow the included instructions to position the battery, microphone, speaker, voice-disguiser, record/play and speed-control modules on the construction base. Connect the circuit using the wires and metal springs, install three AAA batteries and switch the completed device on.

Press and hold the record button to capture a message lasting up to six seconds. Play the message back through the built-in speaker, then rotate the disguise knob to change its playback speed. Turning the control in one direction makes the voice sound higher and faster, while turning it in the other direction produces a lower, slower sound.

Combining construction, electronics and secret-agent role play, this hands-on activity introduces children to simple circuits, microphones, speakers, sound recording and variable resistance. It also supports logical thinking, problem-solving and fine motor development.
