Bibliography14 Introduction You wouldn't think a loudspeaker and a car engine have a lot in common, would you? Well perhaps not a lot but they definitely share one important thing – both have seen almost no change to their fundamental form in decades. Of course technological progress has supplied them with more sophisticated materials. Hence nowadays they are more efficient than ever before. However, the car still uses a series of small sparks to get from point A to point B and we still use the speaker cone to move air particles. Period. But is it really that simple? Certainly not. Since I have limited knowledge of car engines, I will instead focus on the principles of functionality and design of dynamic moving coil loudspeakers. There are a great many different designs of loudspeakers – ribbon (which actually predate dynamic moving coil design), electrostatic, Heil air motion, plasma (ionic),…

She made me open my eyes to…

    Throughout the entire class, I have been questioning to myself if I have enhanced as a persuasive speaker, or remained as the same person that stepped into your classroom for the first time. And to be frank with you Schilling, my actual objective for Speech 100 was to progress into a decent speaker, so that one day I could possess the same atmosphere as Henry Clay. Bearing in mind that Clay was valued as one of the greatest speakers that has walked on this earth. Likewise, Clay is considered as…

    “Porphyria’s Lover” & “Neutral Tones”: The Sinister Similarities of the Speakers The loss of a loved one is perhaps the most difficult experience that humans ever come up against. The poem “Porphyria’s Lover”, written by Robert Browning, adds a sense of irony to this. At the most superficial layer, the speakers in both “Porphyria’s Lover” and “Neutral Tones”, written by Thomas Hardy, both deal with loss. The tones in “Neutral Tones” seem to be indifferent, or Neutral. The speaker of…

    This is similar to a loudspeaker, it being simply an electronic sound amplifier. When you wear a behind the ear hearing aid, the microphone picks up sounds around you and turns them into an electric current. The amplifier then changes the size of the current to make it bigger. The loudspeaker then turns the boosted current back into a much louder sound. This louder sound continues to flow through the earmold into the person’s ear, making noises around the person much louder only in that person’s…

    I was glad I put on more deoderant than normal this morning and I really really really missed my Starbucks that I had left in my car. I was daydreaming about how refreashing a mint chocolate chip flavored frappucinno would taste right about now when the loudspeakers went off. Straighting up, I tried to hold back my nervousness about what would be coming next. I probably wasn't the only one who was thankfully the loudspeakers were earsplittingly loud so that we could hear the Official's message…
