The buzzer pin on Helios64 is designed for active buzzer. The one on your photo is passive buzzer.

Passive buzzer requires the system to generate tone while the active one, system just need to supply power (on/off switch). The buzzer itself that generate the tone.

 

you can buy the passive buzzer at electronic component store, the one that sell Arduino etc.
