Have You Ever Tried to Know the Actual Working of the Speakers
Author: Victor Epand   | Posted: 27-11-2007 | Comments: 0 | Views: 8 | Rating: (51)  (?) 
A speaker is that component of the system, or an output device, which takes the electronic signals and changes it into the sound that we would be able to hear. There are a lot of verities of speakers and loudspeakers; for instance, horn loudspeakers, electrostatic loudspeakers, piezoelectric speakers, ribbon and planner magnetic loudspeakers, flat panel loudspeakers, bending wave loudspeakers, distributed mode loudspeakers, plasma arc speakers, digital speakers and much more.
The speaker designs also differ and they very much affect sound quality. Speakers might be remarkable devices but they are not as simple tools as one can guess, especially regarding the mechanism. To know how speakers work, we have to go through the basic understanding of the topics associated with the working of a speaker.
Basics of Sound
Inside the human ears there is a membrane or layer called Eardrum. When it vibrates, the brain considers the source as to be a sound. Change in air pressure, in a quick time, makes sound to hear. When something moves the air particles around it also move; so, when any object vibrates, sound forms. For a speaker to work it needs air as a medium. So, knowing the basics of sound helps in knowing how speakers work.
Differentiating the various sounds
We can differentiate the sound because of two elements, sound wave frequency and air pressure level. Higher wave frequency means air pressure changes faster. We hear the above as higher pitch. And when the opposite happens we hear it as lower pitch. When the amplitude of sound is higher we hear it as a high volume sound.
How microphone works with Speakers
Working of a microphone is more like our ears. It requires a diaphragm to work, which is vibrated when the air pressure is dispersed in an area, making waves. The signal coming from a microphone then gets encoded onto storage medium. Players decode this stored information from the storage medium back to the sound system as an electric signal. It goes through an amplifier, which increases the amplitude. Speaker, in fact, is the ultimate translator of the electric signal. It reinterprets the physical form of electric signal, into the original form picked up by the microphones.
How speaker works in converting the Final Sound
Speakers, which are configured with high capacity components, are capable of translating accurate fluctuations of air pressures, which were earlier caught by the microphones. Speakers use drivers to perform this task. Drivers are designed in such a way that it contains a lightweight diaphragm, which is attached to a fixed frame. A flexible coil of fine wire, which is prepared to move axially through a cylindrical magnetic gap, hangs it.
When the desired electrical signal is applied to the voice coil, it creates a magnetic field caused by the wire, turning it to an electromagnet. Magnetic system of the driver and the voice coil then interacts to form a to and fro motion, making sound. This signal comes through the amplifier, whose objective is to amplify the original captured signal. The speaker is optimized to produce perfect sound captured by the original capturer. How speaker works and the ultimate quality of the speakers depend on the mechanism and components used by the different manufacturers.

What if the Two Seas Meet? in Bible and Quran
By: Prof.dr. Ibrahim Khalil | 21/06/2007 | Humor
The Meeting of Two Seas is mentioned once in the Bible and four times in the Quran. This is one of the rare examples of an issue that is mentioned in the Quran more frequently in comparison to the Bible. According to the Bible, where two seas met, they ran the ship aground; and the forepart stuck fast, and remained unmovable, but the hinder part was broken with the violence of the waves.
On the other hand, the Quran preceded the Oceanography and mentioned that there is a barrier at the Junction between two seas that meet and that they do not transgress. Also, the Quran talks about the divider between fresh and salt water, it mentions the existence of "a forbidding partition" with the barrier.
In addition, the Quran says that there are two types of Pearls, the Freshwater and Saltwater Pearls
Historically, the Quran cites that Moses went to the junction where the two seas meet in order to see the blessed knowledgeable. Moses wanted to learn from him. This event is not mentioned in the Bible.

6 channel speakers, custom PC, and a MIC. Please help!
By: whitetiger55 | 10-06-2008
I have a 6 Channel Speaker System. I also have a custom made PC. I recently bought an Ideazon GH-100 headset/mic so that i could use voice chat while gaming. However, when I go to plug in my headset, there are no available jacks, as they are all taken up by my speaker system, including the mic jack. I checked, and do not have a front panel jack system, only back. I've tried unplugging the MIC speaker jack and replacing it with my mic plug in on the headset, but that only creates more problem as it turns my speaker system into 2 channell andthe voice mic won't work at all. At this time of my frustration, all and any help is completely appreciated, so I thank all responses. I am not quite willing to accept that my setup just doesn't alow for a MIC!! :) Thanks! -Fellow PCer
