  2. Microphone - Wikipedia

    en.wikipedia.org/wiki/Microphone

    How the physical body of the microphone is oriented relative to the diagrams depends on the microphone design. For large-membrane microphones such as in the Oktava (pictured above), the upward direction in the polar diagram is usually perpendicular to the microphone body, commonly known as "side fire" or "side address". For small diaphragm ...

    † Although the mic input is usually mono, the input is still a TRS phone socket. Many mono 'computer' mics are fitted with TRS plugs. The tip is for the MIC and the ring is for power (to power an electret-condenser style MIC). There are exceptions to the above: Hosa cables use grey and orange for left and right analogue channels.

  4. Computer hardware - Wikipedia

    en.wikipedia.org/wiki/Computer_hardware

    Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1] [2]

  5. Input device - Wikipedia

    en.wikipedia.org/wiki/Input_device

    A user presses a key which transfers information to a computer. In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. Examples of input devices include keyboards, computer mice, scanners, cameras, joysticks, and microphones.

  6. Peripheral - Wikipedia

    en.wikipedia.org/wiki/Peripheral

    A peripheral can be categorized based on the direction in which information flows relative to the computer: The computer receives data from an input device; examples: mouse, keyboard, scanner, game controller, microphone and webcam; The computer sends data to an output device; examples: monitor, printer, headphones, and speakers

  7. Boundary microphone - Wikipedia

    en.wikipedia.org/wiki/Boundary_microphone

    Two examples of different boundary mics (top) and a diagram of the elements of a boundary microphone. The diagram shows the location of the mic capsule, the plate, the aperture, and the pressure zone. In 1978, audio engineers Ed Long and Ron Wickersham studied the effects of the boundary layer in sound recording.

  8. Microphone connector - Wikipedia

    en.wikipedia.org/wiki/Microphone_connector

    Two pins are used for the mono headphone signal and two pins for the unbalanced microphone signal. The 4-pin XLR connector is also commonly used on amateur radio microphones, but transferring unbalanced audio instead, and using the 4th pin (with the common ground) for a push-to-talk (PTT) circuit activated by a button on the microphone.

  9. Electret microphone - Wikipedia

    en.wikipedia.org/wiki/Electret_microphone

    An electret microphone is a microphone whose diaphragm forms a capacitor (historically-termed a condenser) that incorporates an electret.
