Definition of cardioid in English:

cardioid

noun ˈkɑːdɪɔɪdˈkɑrdiˌɔɪd

Mathematics

1A heart-shaped curve traced by a point on the circumference of a circle as it rolls around another identical circle.
〔数〕心脏线
Example sentencesExamples
- There are exactly three parallel tangents to the cardioid with any given gradient.
- M is the point of the moving circle that traces the cardioid.
- For the special case of b = a, the result is a two-dimensional heart-shaped curve known as the cardioid.
- The caustic of a circle with radiant point on the circumference is a cardioid, while if the rays are parallel then the caustic is a nephroid.
- If the focus of the parabola is taken as the centre of inversion, the parabola inverts to a cardioid.
1. 1.1 A directional microphone with a heart-shaped pattern of sensitivity.
  Example sentencesExamples
  The wide cardioid does make them more sensitive to what's going on off-axis, so be mindful of things like nearby walls when you're positioning them.
  We had Sennheiser MKH20s as the flanking mics and more Sennheiser MKH Series mics used in the surround pickup; then across the front of the chorus was the B&K DPA 4023 miniature cardioids.
  The DPA 4015's wide pattern provides a welcome intermediate alternative to omnis and so-called first-order cardioids.
  Because the rear lobes of these hypercardioids tend to ‘cross’ the channels of the front stereophonic image, a ‘purist’ might prefer to use cardioids.
  These microphones are invariably cardioid microphones, meaning that the shape of the sound sensitive field around the mike is in the shape of a heart, essentially picking up sound in both forward and side directions.
  DPA calls this mic a wide cardioid, and, indeed, between 500 Hz and 10k Hz, the 4015's polar response begins to resemble an omni mic.
  For the upright, I used two mics: one cardioid large-diaphragm near the floor, pointing up at the bridge, and the xt up closer to the players' right hand to capture more of the string noise and attack.
  MG recommends its low-noise M930s, but it works fine with any studio cardioids.

adjectiveˈkɑːdɪɔɪdˈkɑrdiˌɔɪd

Of the shape of a cardioid.

Example sentencesExamples
- His first two papers are on the cardioid curve which he named.
- A similar procedure can be used for the intersection points on the cardioid shape and the outer green fringes.

Origin

Mid 18th century: from Greek kardioeidēs 'heart-shaped', from kardia 'heart' + eidos 'form'.
