IMPROVED HARMONICA Russian patent published in 2024 - IPC G10D7/14 

FIELD: musical instruments.

SUBSTANCE: labial harmonica (100), preferably diatonic, comprising a comb with a group of chambers (131), each of which comprises opening (135), made with possibility of passage of the user's breath, wherein each chamber (131) forms oscillating space (112) for exhalation tab (111) and oscillating space (122) for tab (121) for inhalation, first plate (110) comprising a group of exhalation tabs (111), wherein first board (110) is located opposite to first surface of comb (130), each tab (111) for exhalation of group of tabs (111) for exhalation is made with possibility of oscillation in its oscillating space (112), when a user blows into at least chamber (131) defining said oscillating space (112); second board (120), comprising a group of tabs (121) for inhalation, wherein second board (120) is located opposite lower surface (130b) of comb (130), wherein each tab (121) for inhalation of group of tabs (121) for inhalation is made with possibility of oscillation in its oscillating space (122), when the user inhales from at least chamber (131) defining said oscillatory space (122). Part of chambers (131) from group of chambers (131) comprises protrusion (140) of material, which is located opposite a portion of tab (121) for inhalation and is configured for oscillation of tab (111) for exhalation of an additional pair of said tab (121) for inhalation, when the user inhales from chamber (131) of said tab (121), preferably positioning the tongue so that tab (111) oscillates.

EFFECT: expansion of functional capabilities of harmonics.
