For recording a microphone needs to be connected to a preamplifier. Other than this the condenser microphone & the piezoelectric microphone are some of the procedures usually follow. There are many processes to do that but the most common is a dynamic microphone that uses a coil of wire suspended in a magnetic field. The Function of a MicrophoneĪ microphone or mike converts the air pressure variations of a sound wave to an electrical signal. Later Thomas Edison has refined this into a carbon-button transmitter in 1886. Later German inventor Johann Philipp redesigned an early transmitter that used a metallic strip attached to a vibrating membrane that would produce intermittent current but a better result came with "liquid transmitter" designed by Scottish-American Alexander Graham Bell in 1876.ĭavid Edward Hughes invented a carbon microphone in 1870 that is the direct prototype of today's microphones and was critical in the development of telephony, broadcasting, and the recording industries. In 1665 Robert Hooke was the first to invent the process of stretched wire with a cup attached at each end for transmission. Based on our formula, the EVGA would cost $11.31 per year to run, compared with the Dell's $43.38 and the Gateway's $59.67.Use High-Quality Microphones for your Studio available at the Best Price in BangladeshĪt the very beginning, acoustic megaphones were used for the amplification of the human voice. The InterView's standby mode drew 3.1 watts compared with the Dell's 's 1.41 watts and the Gateway's 17.01 watts. In our power consumption tests, the 34-inch (two 17-inch screens) EVGA InterView drew 30.13 watts in its Default/On mode-compared with the 30-inch Dell 3007WFP's 142.14 watts and the Gateway XHD3000's 160.36 watts. Of course, when viewed from the optimal angle, we had no problems. From the sides, text is still readable until viewing from about 60 degrees. When we viewed the EVGA from the sides or below, the screen appeared to darken only a couple inches from optimal. ![]() TN panels get overly bright or overly dark when viewed from nonoptimal angles. Like most monitors, the EVGA InterView uses a TN panel in each screen. Since most monitors are made to be viewed only at that angle type, picture quality at nonoptimal angles varies depending on the monitor. At this angle, you're viewing the colors and gamma correction as they were intended. The optimal viewing angle for a monitor is usually from directly in front, about a quarter of the screen's distance down from the top. Also, during fast movement, when we'd spray our guns around horizontally, the image became noticeably blurry. Unreal Tournament 3 also looked a bit drab running at 1,440x900, with muddled colors. Unfortunately, at $650, you'll have a tough time getting your IS department to pay for it. Really, it's a business-minded person who will benefit most from this dual-screen setup (unless two 17-inch monitors just aren't enough). Casual users should steer clear, considering the price of the EVGA InterView, lack of connection options, and lower-than-average performance. Also, the screens' capability to flip back 180 degrees is a useful addition for people who conduct meetings in their offices. That being said, the unit's dual-screen feature is incredibly useful and actually does seem to increase productivity by allowing more screen real estate for multitasking. The EVGA InterView looks impressive on a desk, but its performance with games, movies, and on our DisplayMate tests is below average. Its notable amenities include an integrated Webcam, three USB ports, and a built-in microphone. The EVGA InterView is essentially two 17-inch monitors combined into a single unit at the cost of $650.
