  2. Microphone - Wikipedia

    en.wikipedia.org/wiki/Microphone

    As with directional microphones, the polar pattern for an "omnidirectional" microphone is a function of frequency. The body of the microphone is not infinitely small and, as a consequence, it tends to get in its own way with respect to sounds arriving from the rear, causing a slight flattening of the polar response.

  3. Boundary microphone - Wikipedia

    en.wikipedia.org/wiki/Boundary_microphone

    The boundary microphone can be used as a piano mic by placing it inside the piano lid, an approach which can obtain better pickup of the piano's mix of sharp percussive transients and gentle undertones than other microphone options. Boundary mics are used on hockey boards for body check sound effects. They are also commonly used to record full ...

  4. Carbon microphone - Wikipedia

    en.wikipedia.org/wiki/Carbon_microphone

    The carbon microphone, by virtue of using a power supply, gives a power gain. This can readily be demonstrated by connecting a battery, microphone and earphone in series. If the microphone and earphone are brought in contact the system will oscillate. This is only possible if the power gain around the loop is greater than unity.

  5. Ribbon microphone - Wikipedia

    en.wikipedia.org/wiki/Ribbon_microphone

    In 2007, microphones employing ribbon elements made of strong nanomaterials became available, offering orders of magnitude improvement in signal purity and output level. [18] The ribbon microphone is an electrically simple design with no active circuitry; it is possible to build one from a kit, or with basic tools and materials. [19]

  6. Lavalier microphone - Wikipedia

    en.wikipedia.org/wiki/Lavalier_microphone

    When lavalier microphones are concealed under clothing, the clothing often scratches against the microphone. To minimize this problem, sound recordists sometimes wrap the head of the microphones in moleskin or place it inside a hollow-centered, column-shaped sponge and place it under a placard, behind a button, or within the knot of a tie.

  7. Wireless microphone - Wikipedia

    en.wikipedia.org/wiki/Wireless_microphone

    A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone , it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the ...

  8. Diaphragm (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_(acoustics)

    Microphone diaphragms, unlike speaker diaphragms, tend to be thin and flexible, since they need to absorb as much sound as possible. In a condenser microphone, the diaphragm is placed in front of a plate and is charged. [2] In a dynamic microphone, the diaphragm is glued to a magnetic coil, similar to the one in a dynamic loudspeaker.

  9. Microphone stand - Wikipedia

    en.wikipedia.org/wiki/Microphone_stand

    A microphone stand. A microphone stand is a free-standing mount for a microphone. It allows the microphone to be positioned in the studio, on stage or on location without requiring a person to hold it. The most basic microphone stand is a straight stand.
