Summary
[edit]DescriptionHorn (instrument).jpg |
English: A bulb horn, used on bicycles as a warning device. Squeezing the black rubber bulb forces air through a reed at the throat of the metal horn, making it vibrate, creating sound waves. The metal horn couples the vibrations efficiently to the outside air, increasing the loudness of the sound. |
