Many performers, clutching the microphone head with the palm of using a wireless microphone dragged four microphones, microphone sound quality is severely damaged and the directivity of the most bad posture, using the microphone in such a posture, even the choice of the most expensive civil victory speech microphone excellent characteristics microphone, but also make the original has, thus losing tone! Clinging to the head with the palm of net result is equal to the first sound isolation chamber surrounding sound loops or change the resonant frequency of the gas chamber, will lead to a positive resolution of the frequency response characteristics of the microphone and pointing to a serious deterioration of characteristics, but because of the sound of the palm of poly effects caused by the resonant frequency of a certain period of enhanced feedback generated sound. Although wireless microphone because there is no online entanglements, safe and easy to use, but users often do not have the heart to take the correct posture study microphone, any microphone caught in nets head, so the use of the microphone position will certainly lose the superior characteristics of the original microphone . A concert to exploit the microphone to a wonderful song reprise of the original, he must first learn to take the microphone correct posture. Take the microphone position is very simple, just remember one important principle: No matter what you get, is not caught in the net of the microphone head; the correct use of gesture, who should hold the tube microphone. Microphone in the current plays an important role, especially in the growing wireless technology, the wireless microphone has replaced the traditional wired microphones are widely used. Wireless microphone audio signal through a microphone is converted to an audio electric signal, junction capacitance is changed by changing the output frequency of the high frequency oscillator, frequency modulation wave generating video conferencing omnidirectional microphone interface, through the high frequency amplification and frequency selection, radiated by the antenna. Receiving signals through the receiver and converted into an audio signal can be achieved remotely sound propagation. Compared with easy to use, nice advantage in the process does not require the use of long cables, cable brought out of the poor. With the development of modern science and technology, wireless microphone types become more feature also will become strong video conferencing omnidirectional microphone interface, microphone, video provided by Wuhan Wuhan Jiuhua Jiuhua Video Engineering Limited.
