Understanding Sound, Sound Blanket and Condenser Sound Box
Condenser sound is a diaphragm-shaped plate that moves back and forth as sound waves pass through it. In a full-range, full-range or super-sonic speaker, the diaphragm moves forward and backward at high speeds when the speaker is being driven. The sound waves that pass through the diaphragm come out as sound in your stereo. If you have a boom box, the diaphragm creates a resonant cavity, or chamber, which allows sound waves to form in one location and travel to another. Condenser and dome tweeters are sometimes described as similar devices.
Sound waves are inaudible until they reach the ear of an audience. The most common thing to happen is the speaker’s cone vibrates as a result of the sound waves that pass through it. If the cone does not have any air spaces between its leading and trailing edges, the cone will be flat. With a flat cone, there will be no one to resonate and produce sound. A full-range speaker will have the cone, which will vibrate when the sound waves pass through it.
A woofer is the most difficult of all speakers to make. When the sound waves hit the diaphragm, they are absorbed by the cone and deflected by the medium in which they are traveling. The intensity of the reflected wave depends on the relative sizes of the cone and the diaphragm. The cone absorbs some sound waves and reflects others. As long as the surface area of the cone is less than the diaphragm’s area, the resulting sound waves will cancel each other out. However, when the cone is larger than the diaphragm, some sound waves are reflected back into the speaker and others are absorbed. The resulting sound waves are so different that a listener may be able to tell which one they are.
