Mini 8 ohm Speaker with Wire Leads - 0.5W

This mini speaker produces 0.5 Watts of sound which is perfect for sound without lots of power-drain. It can be hooked up to most audio devices that support headphones. Great for having your robot talk/adding soundtracks to your electronics projects.

The internal resistance/impedance of 8 ohms (most common for speakers) tells you what you need so you can determine the amount of current (Amps) your speaker will have running through it using Amps = volts/resistance where volts is the output voltage of your amplifier/audio producing device and resistance is the resistance of your speaker(s). This is useful for someone looking to hook up multiple speakers to one output.
