| ⚫ | However, probably more typically there is no movement of air at all, contrasting with the burst of the pulmonary plosives. This is the case with many of the [[Kru languages]], for example. Note that this means implosives are phonetically sonorants (i.e. not obstruents) as the concept of sonorant is usually defined. However, phonologically implosives can pattern as both, that is they may be phonological sonorants or obstruents depending on the language. |

The vast majority of implosive consonants are [[Voiced consonant|voiced]], meaning that the glottis is only partially closed. Because the airflow required for voicing reduces the vacuum being created in the mouth, implosives are easiest to make with a large oral cavity. Thus bilabial {{IPA|[ɓ]}} is the easiest implosive to pronounce, and also most common around the world. Velar {{IPA|[ɠ]}}, on the other hand, is quite rare (and uvular {{IPA|[ʛ]}} even rarer). This is the opposite pattern to the [[ejective consonant]]s, where it is the velar articulation that is most common, and the bilabial that is rare. |

Una consonante implosiva es un tipo de oclusiva (marginalmente puede ser una africada) con un mecanismo mixto de corriente, glotálico ingresivo y pulmonar egresivo.[1] Es decir, la corriente de aire se controla por movimientos arriba y abajo de la glotis combinado con un flujo saliente de los pulmones. Por tanto, a diferencia de las consonantes eyectivas cuyo mecanimso el glotálico puro, las implositvas pueden ser modificadas mediante fonación. Las implosivas casi de manera universal presentan fonación sonora. Las consonantes implosivas se encuentran en aproximadamente el 13% de las lenguas del mundo.[2]
En el AFI, las consonantes implosivas se indican modificando la correspondiente oclusiva sonra mediante un gancho a la derecha en la parte superior: [ɓ ɗ ʄ ɠ ʛ].
Articulación
Durante la fase de oclsuión de la consonante, empujar la glotis hacia abajo enrarece (reduce la densidad) el aire del tracto vocal, y en ese momento la oclusión se libera.
