An acoustic instrument soother for infants and young children, combining a pacifier, a teether, and a mouthguard with a harmonica to generate sound. The device incorporates non-electronic musical elements, aiming to soothe and entertain young users while fostering early musical education. The harmonica component features multiple mouthpieces for sound production, activated by the user's inhalation and exhalation. Through the integration of music notation symbols engraved on its surface, the device provides vocal and music notation lessons, enhancing the user's auditory and cognitive development.

The present invention discloses a harmonica reed plate and a harmonica, and belongs to the field of musical instruments. The harmonica reed plate has different thicknesses by controlling reed slots. Specifically, a groove with fixed depth is milled on the opposite surface of the target reed slot for fixing the reeds so that the reeds obtain an optimal vibration thickness different from the thickness of the original material after fixation to customize an equivalent reed plate thickness for each reed slot (reed) without the need to select a compromised thickness to take into account all the reed slots like the traditional harmonica reed plate. The harmonica prepared by the above harmonica reed plate can realize the optimal vibration mode of bass and treble at the same time on one reed plate, and can control the deviation of timbre, volume and pitch, which is more conducive to playing.

A harmonica positioning device includes a yoke, support member, gear arrangement, and motor. The yoke encircles the musician's neck. A first portion of the harmonica support member releasably couples to a harmonica, and a second portion secures to a shaft that co-rotates with one of the gears, which are housed within the yoke. A wireless foot pedal controls the motor to drive the gears to rotate to thereby rotate the harmonica between a first position and a second position. The motor and gear arrangement is particularly configured to provide friction and a stall torque that holds the harmonica support member in an upright position even while the user is playing the harmonic, without using a dedicating locking mechanism. An encoder detects rotation speed and rotation angle of the motor to control the motor to limit movement of the harmonica support member to at least the first and second positions.

The invention relates to musical instruments, to their body pad or comb parts and can be used in the manufacture of harmonicas. Harmonica pad made in the form of a body part of a harmonica comprises air passage channels inside, each of which is formed by combined communicating internal volumes of horizontal inlet and vertical outlet through holes and said channels comprise one or two bypass holes made with the intersection of said horizontal inlets for each channel. When one or two bypass holes of the corresponding channel are completely closed, the maximum flow rate and pressure of the air passing through the vertical through outlet for the reeds of the plates is achieved. Accordingly, when one or two bypass holes of the corresponding channel are fully opened, the minimum flow rate and pressure of air passing through the vertical through outlet for the reeds of the plates is achieved.

Harmonica accordion is a musical instrument, analogical in design to conventional harmonicas; however, it has qualitatively different wider opportunities for the performer. Namely, in addition to solo play it can be used as an independent accompanying instrument, as well as to combine solo play with accompaniment. Furthermore, it allows to accompany in many (or even all) keys, and for each key it has all chord functions. This is achieved due to an arrangement of notes that the reeds are tuned in, i.e. due to a specific tuning. In addition, the instrument uses an additional bass body to play bass tones for all the chords and flow voicing in the accompaniment. The instrument is
