Origins and History of Type-Type of Microphones (PART 3)

(Our Tech Blog) This post continues my previous post. If you have not read it silhkan read on Origins and History of Type-Type of Microphones (PART 1) and Origins and History of Type-Type of Microphones (PART 2)


7. Ribbon microphone



Ribbon microphone is a microphone made ​​of ribbons that are very sensitive and thorough. The workings of the microphone is guided by a central band of thin metal foil that is attached to a magnetic field. That captured the sound vibrations cause movement of the ribbon. The movement resulted in changes in the magnetic field which then generate electrical signals. Therefore ribbon microphone at the beginning of its appearance is a microphone that can display the most natural sound, the recording industry and broadcast immediately take advantage of this microphone at the beginning of the 1930s. Microphone does not require a power supply or batteries to operate. Large growth on the type of microphone can be seen from the large public interest in home recording with a ribbon microphone that provides high-quality microphones made ​​by companies such as AEA Royer, who later became the standard for the studio with Chinese companies such as Sontronics, SE and the Golden Age.

8. Shotgun Microphone MC


Michrophone is shaped like a slim and long-barreled rifle that is often found to be characteristic Condercer Microphune. Sharpen its sound so weak and distant voices will be captured by the microphone is therefore with a shotgun mic does not need to be close to the target object because the grasp of the mic. Directional shotgun straight (one way).

9. PERSONAL MICROPHONE

Lavalier mic / personal mic / clip-on mic is a voice recorder which is small and the brace is used mostly for interviews in studio.lavalier's "mic clip", mic bias that has the characteristics of omni, in European countries popularly known as "Lapel". On call as usual clipped Lapel collar, coat or stick behind the tie. Installation distance of about 6 to 8 inches below the chin about 25cm - 30 cm.


10.HANDHELD MIC



This microphone to record it the same way with another mic but the mic is designed larger handhelds. The size of this mic for hands and used for the purposes of the field at the time of interview coverage. Dynamic mic characteristics Hendheld michrophone muffle its sound sharp desis.suara to reduce noise recorded major, so not eliminate noises.

11.CONTACT MIC


This thing is basically a microphone. But, in contrast to the usual functions of microphones used for singing, this one is able to tap the sound level is more fragile. Contact Mic is designed to be able to penetrate the sound wave damping is virtually unable to capture sound waves below the surface of certain solid. Thus, this microphone can also be used as a bomb detector.

This thing is made integral with the contact element, and has an internal automatic gain control so it no longer requires the adjustment knobs. Contact Mic is designed to convert minute vibrations to sound waves and then can diterjermahkan into the audio band can be heard through headphones or other sound receiving equipment.

Thus, these objects can provide information about what is strange is happening.For countries that are vulnerable to bombs (and earthquake), this tool can be very useful. Certainly it would be much needed for corporate purposes and in institutions or security research, although it was likely used for personal needs. Well, who knows there are curious to know whether the mysterious neighbor who lived next door was a terrorist.

12.BOUNDARY EFFECT MIC



Lavalier mic / personal mic / clip-on mic is a voice recorder which is small and the brace is used mostly for interviews in studio.lavalier's "mic clip", mic bias that has the characteristics of omni, in European countries popularly known as "Lapel". On call as usual clipped Lapel collar, coat or stick behind the tie. Installation distance of about 6 to 8 inches below the chin about 25cm - 30

13.STUDIO MICROPHONE


This unique metal screen not simply perforated but louvered at a little angle to redirect ultra-low frequencies that pass through the blast of breath side of the screen. This process does not attenuate high frequencies, as fabric screens do, and leave the vocal performance unaffected but without annoying low frequency "appears" It's also built to last and will take more abuse than a traditional fabric shield, so it is very good for commercial applications

14.Bidirectional Microphones



Bidirectional microphone. The third type of microphone pattern of polarity is bidirectional (also known as Figure 8). A bidirectional mic will take votes from both the front and rear, but not from all the way around. They do not take votes from both sides at all. Bidirectional mics are often used to play the instrument miking two parts simultaneously, such as the horn. When a bidirectional mic is placed between two horn players with a mic side perpendicular to the players, it will take the sound of horns and very little else. Bidirectional mics are made in three types of microphones: dynamic, condenser, and ribbon.

15.Unidirectional mics


A unidirectional microphone is sensitive to sound from one direction. The diagram above illustrates some of these patterns. Microphone facing upwards in each diagram. The intensity of the sound of certain frequencies is plotted for radial angles 0-360 °. (Professional diagrams show these scales and include multiple plots at different frequencies. The diagrams are given here only give an idea of ​​the typical pattern of shapes, and their names.)

16.Omnidirectional 


An omnidirectional (or nondirectional) microphone response is generally considered to be a perfect sphere in three dimensions. In the real world, this is not terjadi.Seperti directional microphone, the polar pattern for an "omnidirectional" microphone is a function of frequency. Microphone body is not infinite and small, as a result, he tends to get his own way to the sound coming from behind, causing a little flattening of the polar response. Evenly increased in line with the diameter of the microphone (assuming it is cylindrical) reaches the wavelength of the frequency concerned. Therefore, the smallest diameter microphone will give the best omnidirectional characteristics at high frequencies.
