It has multiple, variably-tuned brass or bronze reeds which are secured at one end over an airway slot into which it can freely vibrate. The vibrating reeds repeatedly interrupt the airstream to produce sound.
The player selects the notes by the placement of his or her mouth over the proper airways. These holes are usually made up of discrete holes in the front of the instrument. Each hole communicates with one or more reeds, depending on the type of harmonica. Because a reed mounted above a slot is made to vibrate more easily by air from above, reeds accessed by a mouthpiece hole often may be selected further by choice of breath direction (blowing, drawing). Some harmonicas, primarily the chromatic harmonica, also include a spring-loaded button-actuated slide that, when depressed, redirects the airflow.
The skin of the drum vibrates to produce sound.
the manjira itself vibrates to produce sound
The accordion reed, which is made of highly tempered steel, vibrates when air is driven through the reed plates by the push/pull movement of the bellows to produce sound.
The harmonium is a reed organ. Therefore, the sound is produced by the brass reeds when air passes through them.
streched membrane
The strings.
The membrane of tabla vibrates to produce a sound.
We just learned about this in science class. Air vibrates throughout the tube part and out the bell to produce sound waves.

Most percussion and string instruments operate of vibrations to produce sound. Drum heads, xylophone bars, strings and reeds all vibrate on instruments that use them to produce sound.
They both have stretched membrane or a drumhead which is hit and the one that vibrates to produce that sound of the drum.
Your two vocal cords produce the sound. This pair vibrates to produce the phonation or sound. Then your tongue, palate, cheeks and lips take part to give the talk its final touch.
