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.

A wind instrument such as a harmonica has a mouthpiece with one or more air channels, an electric power source, and a means for generating an electrical output signal from strain gages exposed to airflow in the channels. First and second strain gages having variable flow-induced resistance are bonded to a flexible substrate and suspended within an air channel, which includes a divider shelf for directing a first airflow to the first strain gage and a second airflow to the second strain gage. Complimentary strain gages are mounted to an opposite side of the substrate for inverse flexure to enable temperature correction for the first and second strain gages. When a user forces air through a channel in a direction biased to one side of the divider shelf a difference signal is generated by the first and second strain gages and detected by comparing their outputs. The difference signal can be used to adjust a variable control signal in applications such as volume control, dimming lights, or bending notes generated by the harmonica.

Accumulated saliva, other liquid and/or debris is removed from the interior of a harmonica by placing the harmonica in a carrier and twirling the carrier in an orbital path. The saliva, other liquid and/or debris is ejected from the holes or the harmonica by centrifugal force.

A chromatic harmonica with reduced air leakage in which a flexible mouthpiece replaces the conventional rigid mouthpiece, and a low friction valve slide replaces the conventional valve slide, thereby allowing the low friction valve slide to move horizontally when played without binding, and which eliminates the need for a gap between the mouthpiece and valve slide through which air leaks. For the chromatic harmonica with a flexible mouthpiece to function properly, a new button configuration is added. The button is disposed in the rear portion of the chromatic harmonica. A bar is attached to the button at one end of the bar, and the other end of the bar inserts into an opening in the valve slide. The button further comprises a cylinder, around which a spring is disposed. The cylinder inserts inside of a hole on a side of the chromatic harmonica adjacent the rear.

A reduced air leakage harmonica reed unit contains a reed plate and a plurality of reed sections. The plurality of reed sections is attached to the reed plate with a fastening mechanism and positioned within a body of the harmonica. The reed plate consists of a plate body and a plurality of receiving slots that traverse through the plate body. The plurality of receiving slots are aligned with a U-shaped channel from each of the plurality of reed sections. Thus, air that is drawn or blown travels through the U-shaped channel from the plurality of reed sections and through the plurality of receiving slots. Since the U-shaped channel is precisely cut, air leakage is minimized and high quality sound is produced by triggering a vibrating membrane.

An attachment for a harmonica or a pulmonary harmonica may include a resistance band or modified comb which increases respiratory resistance from the typical open holes of harmonicas. The resistance band or modified comb may prevent a broken reed from being inhaled into the mouth.

The present utility model is a mouthpiece of a wind instrument, an electric harmonica, an electric blowpipe, and a wind instrument. The mouthpiece for a wind instrument comprises air chambers, disposed in the housing of the wind instrument; air pressure sensors, disposed at the bottom of the air chambers for detecting air pressure changes within the air chambers; an air intake channel, disposed on the outer side of the air chambers, and when air is blown into the air intake channel. The air chambers produce pressure changes which are detected by the air pressure sensors. Air vents, disposed on the air intake channel, are configured for airflow to enter the air intake channel and be discharged from the air vents, and the path thereof changes. Such a configuration can improve user comfort, reduce poor hygiene within the instrument, and reduce the chances of inadvertent sound output.

The invention relates to improvements to the harmonica holder, which allows the musician to play the harmonica and another instrument at the same time. The inventor's control arm and extender tubes allows the musician to adjust the position of the harmonica (in the horizontal and vertical plains). After adjustment, the control arm allows the musician to quickly raise the harmonica up to the adjustment position, which locks the harmonic in place and eliminates the need to re-set the harmonica each time it is used. To unlock the harmonica and drop it completely out of the way for singing or to remove the harmonica from the musician's head area, the musician would simply tap the end of the control arm up, to disengage it. The pull down loop (attached to the harmonica cross member) allows the musician to quickly change harmonicas from one key to another.
