Head-mounted noise-reduction earmuff for magnetic resonance imaging

The invention discloses a head-mounted noise-reduction earmuff for magnetic resonance imaging. The head-mounted noise-reduction earmuff for magnetic resonance imaging comprises an arc-shaped retractable rack, wherein two ends of the retractable rack are fixedly connected with earmuff shells separately; a metal sleeve extends out from the inner wall of each earmuff shell; a miniature loudspeaker is arranged at the inner end of each metal sleeve; a wire of the miniature loudspeaker extends along the inside of each metal sleeve and penetrates out of a hole in the metal sleeve; and a sponge sleeve sleeves each metal sleeve which extends out from the inner wall of the corresponding earmuff shell. The head-mounted noise-reduction earmuff for magnetic resonance imaging is reasonable in design, novel in conception, simple in structure and convenient to operate; the sponge sleeves can be plugged into ear holes to insulate sound, the effect is good, the metal sleeves which support the sponge sleeves are adjusted to be
