KIT CONTENTS Vibration speaker Bag of sand Plastic tray Protective film for speaker (on the speaker’s adhesive pad) YOU WILL ALSO NEED: Two AAA batteries (1.5-volt, type AAA/LR03); small Phillips head (cross-head) screwdriver; audio source such as an MP3 player, cell phone with headphone jack, or sound system;... -
Page 6: Installing The Batteries
POWERING UP WITH BATTERIES Installing the batteries You will need: You will first have to install batteries Vibration speaker, two AAA batteries in the sound booster. It’s best to let (1.5-volt, type LR03), small Phillips an adult help you. Open the battery head (cross-head) screwdriver compartment by loosening the small screw on the bottom of the device. - Page 7 USING YOUR GEEKER SPEAKER Here’s how: How to use the vibration speaker Make sure you have installed the two AAA batteries correctly, and that the batteries are charged. You will need: Vibration speaker; an audio source Your vibration speaker has a short such as an MP3 player, a cell phone wire on the bottom with a 3.5-mm...
- Page 8 IMPORTANT! Do not throw away the protective plastic film that was stuck onto the adhesive pad. It protects the adhesive pad from getting dirty. You can keep using the adhesive pad over and over. If the adhesive pad does get dirty and won’t stick well anymore, simply wipe it off with a damp finger.
- Page 9 NEW WAVES: SPEAKER EXPERIMENTS Experiment 1: Music without a resonating body Here’s how: Connect the vibration speaker to an audio source and start the music. Remove the vibrating pod from its housing and take a look at it. Can you see the way the speaker membrane vibrates along with the music? What’s happening?
- Page 10 Experiment 2: Various materials You will need: Vibration speaker, audio source, a selection of various objects and materials from around your home or classroom Here’s how: Remove the protective film from the vibrating pod, stick the speaker onto whatever object you have on hand, and start the music.
- Page 11 Experiment 3: Pour just a little sand into the Making sound visible tray — not so much that the bottom of the basin would be completely covered if the sand You will need: was spread out evenly. Vibration speaker, black plastic tray, sand, audio source, two books or Start your music, ideally a song blocks, adhesive tape...
- Page 12 Experiment 4: Making sound visible in water You will need: Setup from Experiment 3 Here’s how: Try the “Making sound visible” experiment with water. It also produces some very interesting visual effects, even though it looks totally different. You can also try a combination of sand and water.
- Page 13 Bonus Experiment: With a signal generator app, Frequency patterns you can produce much more consistent sound patterns than with music. Use the You will need: same experiment setup as in Setup from Experiment 3, the “Making sound visible” smartphone or tablet, signal experiment.
- Page 14 WHAT IS SOUND? The sound that we hear is nothing If we could see this, it would look other than compressed air something like the waves that are pushing against the inner parts created when you toss a rock into the water, only in three dimensions of our ears.
- Page 15 GOOD VIBRATIONS: SOUND FREQUENCIES Sound is indicated in frequencies. The frequency indicates how many waves there are per second at a particular spot. As mentioned on the previous page, a sound wave in this sense can be thought of as a change from most compressed state to least compressed state and back again.
- Page 16 SEEING SOUND WAVES: CYMATICS Cymatics is the study of techniques for making sounds and sound waves visible. A pioneer of cymatics was the German physicist and musician Ernst Chladni (1756 – 1827). He would draw his violin bow over a thin metal plate to make it start vibrating.
- Page 17 SPEAKER SCIENCE There are many types of speakers. What all speakers have in common is that they convert fluctuations in current into sound vibrations. Speakers can be built in many different ways. But all have a large, flexible membrane to set the greatest possible quantity of air into vibration.
