Figure 1 shows a loudspeaker cone.

A diagram showing a cross-section of a loudspeaker cone with double-headed horizontal arrows indicating its back-and-forth vibration. To the right of the cone, air particles are represented as small dots, showing regions where they are squeezed together and regions where they are spread apart.

When the loudspeaker is connected to an audio signal generator, the cone vibrates in the directions shown by the arrows.

Describe how the vibrating loudspeaker cone causes a sound wave to travel through the surrounding air.
