Description of Wireless Microphones
A computer wireless microphone is a microphone with no tangible cable and is directly connected to the sound recording (sound card) of a computer. Its hands-free feature allows for multitasking.
The wireless microphone technology is now being incorporated in technologies like the mouse, speaker, printer, scanner, and digital cameras. Audio applications include speech recognition, speech dictation, computer telephony, video conferencing, and internet telephones.
The sound card is typically included as package on personal computers and is attached to the motherboard of the PC. It is usually coupled with built-in microphone and line level ports that work in the analog audio signal input and output of the audio data.
One advantage of the wireless microphone system is being able to customize a loud speaker for various modes like speakerphone mode or non-speaker audio mode. These microphones are often joined to the head set and permit you to have the benefit of better quality of music and sounds. The head set microphones also let you move freely in all directions without the risks of possible stumbles or trips.
Nowadays, there are different standards, frequencies, and transmissions of modern devices being used to replace the conventional microphone’s cable connection and turn it into wireless. Wireless microphone can be transmitted in radio waves using UHF or VHF frequencies, AM or FM frequencies or any other digital software scheme. Low cost microphone models make use of an infrared light. To avoid interference, most advanced variations of this device operate selected frequency to facilitate the adoption of several computer programs simultaneously.
The Modern models of computer wireless microphone transmit clear reception. The two separate receiver modules with antennae reduce dead spot in sound waves.
Two Types of Most Frequently Used Digital Transmission Scheme
The Digital Hybrid System uses an FM analog audio signal to combine with Digital Signal Processing (DSP). It enhances the audio spectrum to make it easier to get the right frequency. DSP reduces noise and eliminates undesirable effects. This wireless microphone operates on a high level bandwidth of 200 to 500 kHz.
On the other hand, the Pure Digital System is a frequency-hopping spread technology. It requires more bandwidth than an FM signal and operates at 900 MHz or 2.4 GHz bandwidth.
Where to Use the Computer Wireless Microphone System
Computer Wireless Microphone System is substantially versatile. It can be applied in vehicles associated with cellular phones, transportable video cameras, and other multimedia device. In addition, these device systems can be use in concert halls, live stages, radio stations, or wayside recording. These wireless microphones can function well in other two-way communication devices such as aircraft headsets.
