FIELD: headphones.
SUBSTANCE: headphones contain a speaker, a microphone, and a vibration sensor. The microphone is made with the possibility of reception of the first signal including a voice signal and the first vibration signal. The vibration sensor is made with the possibility of reception of the second vibration signal, wherein the first vibration signal and the second vibration signal come from vibration of a vibration source; and a volume of a cavity of the vibration sensor is larger than a volume of a cavity of the microphone in such a way that the microphone and the vibration sensor have approximately the same frequency characteristic relatively to vibration of the vibration source.
EFFECT: increase in the quality of sound.
