Microphone type and their use
The main work Maikudaiyafuramu behind. Because it is only to create a signal to catch the waves of sound, microphone techniques vary across the aperture. So what technology, Mike’s work the same way. But of course, all use of different microphones and different techniques, uses of its own.
Technically speaking, will be used for various purposes are generally five types of microphone. Since the youngest one, there are currently very popular wireless microphones. They are used to record and broadcast quality. These microphones, and cameras are portable recorder, or speaker can be connected without cables. This system creates together, sending a signal is recorded, there are three components of the action sent to the location of the reinforcement.
This is a real microphone to the lapel clip around the ear or a small fixed first. Then, the sender, the audio signals, signals and FM, VHF band and UHF radio spectrum is converted to a band. The last component of the antenna is to generate a short distance broadcast signal. These microphones, TV shows, band shows and other types of shows and programs will be used.
The following are other types of microphone:
Dynamic: It works with the help of electromagnetic induction. There is also a magnet inducing current line. When the ultrasonic vibration diaphragm, the magnet moves, the move will create a small current. Dynamic as strong, water resistant, they are used mainly stage performances by singers and bands.
Condenser microphone: “The iris is known capacitor make a difference to the distance between the plates of a capacitor plate and vibration. And these changes are amplified to create a measurement signal. But is the voltage across the capacitor from the battery to provide a small condenser microphone. When they can produce high-quality sound, it is used for laboratory and studio recording.
Ribbon microphones: ribbon with the help of these metals in a magnetic field microphone, pause running, connect to the electric microphone. This ribbon is affected by the acoustic signal is generated electrical current flows through this way and that. Ribbon microphones are mainly used to drum cymbals.
Crystal Microphone: This is Mike, get a crystal aperture diaphragm creates a vibration of the sound signal. In fact, using the piezoelectric effect. It is under pressure voltage is that there are some materials such as crystals to convert the vibrations into electrical signals. Nevertheless, the crystal microphone, vacuum tube devices are used, such as domestic tape recorders. They also contact microphone can be used to enhance the sound of acoustic instruments.
Carbon Microphone: The microphone used in the past are on the phone. They are basically a carbon powder, use a thin metal diaphragm on one side. The sound waves hit the diaphragm to compress the carbon dust that they are resistant to change. We need to change the amount of current changes in this resistance.

The reason is that satellite radio has
There are two important features, most people, your car and home: the best satellite radio service as desired quality and content. We usually how clear the sound output quality is said to mention that when compared to terrestrial radio from satellite radio. Content, on the other hand, refers to the quality of transport equipment. This is the satellite radio industry’s two giants where – Sirius and XM Radio – fight. Quality of the receiver, they use technology, the differences are similar for both can be when quality exclusive. Look at the quality and content features of both satellite radio: Radio qualityThe broadcast quality, with a number, 128KB from the / Let for show 44. 1kHz, both of Dejitarurajiosabisupurobaida. This, CD sound quality is equivalent. Satellite radio coverage, the more important factors can provide any number of terrestrial radio stations, but the sound quality, the Sirius and XM Radio will bring more subscribers. They are free programming, VHF and UHF reception is the antenna, cable TV, digital TV or how he worked, subscribers, 80 percent of the U.S. population that has many similarities with the above. This is the same as satellite radio – one that can get free terrestrial radio, satellite radio at an affordable price, come and have a better quality than analogue radio broadcasting. The satellite radio in my mind is free to continue business – and it’s a big selling point. High analog – no sound quality of digital conversion, FM and AM sound characteristic means a hissing noise or other interference in the broadcast. This is especially clear that listening to music on your satellite radio system. The bark is very strong while the high noise level is very clear and accurate. Also, you hear, there are strong in the range of study and more accurate than terrestrial radio in more robust production. The quality of the music will tell you that someone trained in listening, but not quite good as CD quality, it is very close to the user, not the majority of this difference is more noticeable. How do they try to be more quality broadcast content delivery ContentSo now the satellite radio technology and how good we really know Let’s see. One was to fight for the acquisition of exclusive broadcasting of some of the most interesting approach. For example, negotiations XM broadcasts every Major League game to get the exclusive rights in order between the major radio and has been the provider of satellite radio. Wall Street Journal in an interview, President Larry Ejisonmediarisachi Jin said, “Probably because baseball radio broadcasts, subscription of 100% .. so go to it to make too much money, what happens is .. it is not inevitable declaration, “Today is, XM 23% since the company about the subscriber, sending the major broadcast projects such real possibility. Of course while you are reading, terrestrial radio battles involved, tremendous will to fight the two sides. Naturally, the quality of the stage people to work with the best satellite radio industry. Both Sirius and XM radio receiver knows the $ 10 – $ 300 dollars paying people to come get the best wireless service to the content of 12 per month. To my surprise, that the music channels, radio difference between the quality of content, satellite and terrestrial radio made a big theme – Commercial (or rather, lack of commercial satellite radio) are. Sirius and XM radio most of the channels, so only a small production company and country, to retransmit the radio, it will be interesting to consider the side.

Portable wireless scanner – just over the police scanner
Portable radio scanner, and listen to emergency services, often used, other forms of communication, you can hear it too. They are usually used as a hobby, it is also the researchers, is useful for journalists, and volunteers.
From a wide range of frequencies they many people, and received so you, ambulance and fire control air traffic, it is possible to listen to the race team, a police scanner radio they can receive signals much as well as call Although, the police broadcast.
Hand held scanner is the most popular, Uniden radio scanners, especially Yunidenbeakyattosukyana. Start Beakyattosukyana the basic channel model 100 models go all the way up to 25,000 with a channel between the many choices.
Modern scanners are controlled by the microelectronics and microprocessors are designed for portable and lighter. Back to top 1970, when it first came out with they very heavy and slow, expensive, very large and their batteries were heavy. Today’s home design is that they are usually larger because of what they might be small size of the additional features that can not be made portable model.
The scanner capability to store thousands of channels today, you can watch hundreds per second and can be programmed. They are the local VHF and UHF RF frequency is scanned to monitor the zone. Helpful, FM modulation them in various ways, such as is also the acquisition and WFM.
Mobile Radio Base Scanner started as a hobby just for someone who is usually 100 channels is probably sufficient. More sophisticated models up to 25,000 channels. The average scanner up to 40 miles, depending on the selected transmission antenna used. The scanner, typically 29 MHz 512 MHz and has a wide range of frequencies between the scan.
The scanner automatically scans and essentially is a radio receiver adjusts the frequency of at least two. Tasting facilities are broadcast signal can be adapted to filter unwanted interference and less sensitivity of their orders.

Satellite Radio: The Key to Success
He caught most of the recent children’s entertainment industry’s most dynamic and attractive, and satellite radio. Products and audio entertainment has been very popular, it has good music in your car: When coming variety of choices now, a regular CD player, storage and car MP3 players and CD players. When the radio however, comes an even bigger gap – you are a new offer or a single satellite radio can be heard. Some exciting benefits, commercial FM / AM to provide easy programming is not the main reason that the popularity of satellite radio sky, we are high in recent years. Analog radio stations, can not please see the full range of digital satellite, radio sound, it has a noticeable effect on quality. Digital radio via satellite – this country if the signal from the link to the user whenever a particular region is that you do not have a radio station. If they close the quality of original music played by a very traditional AM and FM broadcasting, various forms of noise failure – satellite radio may remove this problem. ContentBecause satellite technology, high-tech equipment (satellites, small portable receiver) is also often regarded as unapproachable and prefer to use traditional radio. Most young people, can not wait to get their hands on the latest technologies, satellite radio is perfect because it is this age group. Satellite radio for you, because it is free of the traditional two years ago, little commercial radio station, media have to pay high prices for many people decide to enjoy. But today, about $ 12 per month subscription, a number of good news, sports and music radio channels. And the best thing is they are commercial free. In many ways, satellite radio was the next most popular idea of the success of DirecTV – the difference is superior broadcast quality, and content are made by great geographical scope. This is satellite radio and terrestrial radio stations really big problem – you can actually win subscribers or listeners looking for lost or most flexible high quality field. Valuable radio content is made available to the general topic of many media to receive satellite radio. Major broadcasting, for example, can be broadcast on satellite radio. That is a hypothesis yet, chances are, only the topic of multiple U.S. more popular, radio show several satellites, whether the Sirius, XM stations are some from the radio and the participating market the new. That’s it boils down to consumers is real potential wantsAnd – it is. Laughed at the idea of paying some of the radio – as long as we know, radio is free. However, following in the footsteps of the cable television industry’s only satellite radio – all Americans are VHF and UHF antennas, even though 80 percent of the program can receive free over paying monthly fees I try to. $ 9. XM and $ 12 95/month. Sirius, the satellite radio 95/month high accessibility, no one can afford to register. And the truth is, satellite radio, again, has proved to be willing to pay for something they used to get free long as consumers spot is eliminated over time. In many cases, radio, commercials are about 12-15 minutes time – did not want to interrupt their radio. Both Sirius and XM Radio knew this when they will begin a paid subscription service, and they are correct, today’s millions of subscribers for each company is. Even if the boom in satellite radio, the automobile industry – today with almost all from major manufacturers to provide a satellite radio receiver is standard or optional for each model.
