Woodwind instruments are grouped into Flutes of Reeds. They are distinct from Brass instruments in that the air they use is not agitated by the player. Sound is produced by directing a stream of air; in the case of Flutes (including the Picolo) the air is blown against the edge of a hole. The air stream is split at the entrance to the hole, and the split stream of air agitates the air column within the instrument. This agitation vibrates the air producing sound.
The Reed sub group require a stream of air to pass between a reed ( usually bamboo) and the body of the instrument. This structure is known as the Ligature. The vibrating reed acts on the air column within the instrument, and the particular sound is produced. In some instances, two reeds are bound, with air passing between to create the vibratory impulse. The Oboe, Cor Anglise, and Bassoon, are examples of such.

Obviously the length of the instrument determines the area of vibrating air. With reed instruments, the shape of the Cone forces the air passage to travel the length of the air passage, and then to reflect back on itself and return back along the instrument. This results in the sound wave being double the length of the instrument. In some instances, this process can happen four times, making the resultant wave four times as long as the instrument!
All of this does mean that the sound waves created are formed by the vibrating air within the instrument, and thus the sound can be heard equally in any direction from the instrument, making these instruments omnidirectional.

In a standard orchestra setting, the Flutes, Clarinets, Oboes, Bassoon and Cor Anglise are seated in the middle between the Strings and the Brass.
