The multiple vibrating consonant is the consonant that is produced by vibrating one of the articulating organs of the human vocal system against another.
The main characteristic of the multiple vibrators is the vibrations caused by positioning some moving part of the vocal apparatus close enough to another part, to the point that when a stream of air passes, the moving part starts to vibrate. The headphones are also sounded in a similar way , because the sound is produced by vibrating the vocal cords , which are in the larynx , these vibrations are not controlled as if they were a single vibration at a time, but there must be a space that is narrow enough for only the passage of air produces the vibration.

In most languages, the “r” is performed as a vibrant alveolar / dental multiple ( AFI [r] ), vibrating the tip or edge of the tongue against the alveolus. And in some other languages, the “r” are articulated vibrations in the uvula [ʀ] , although the vibrating ones are not always represented by the “r”, as in the case of the vibrant bilabial [ʙ] . [ 2 ]
In many languages, are pre-bilabial vibrating nasalised, which originated from the sequences as a plosive sound pre- nasalized preceding a roundedness of relatively higher and high quality, for example, a sequence such as [MBU] , which becomes vibrant, presenting only a short oral occlusion [mbʙu] .
