Abstract
For an improved harmonic model characterized in that the body of the harmonica has coupled a speaker or loudspeaker whose widest part is exterior to the same along its entire length; the diameter of the horn decreases and when it reaches the end of the harmonica it coincides with the thickness of it, it bends over itself and goes back to traverse it, now internally in all its length and always in diminution until the other end of the harmonica; this interior and narrowest half of the horn is to which the air inlet holes stop.
