These components use electromagnetism to convert AC mains power to low-voltage DC power. The varying magnetic fields generated by these components can cause them to physically vibrate at high frequency, resulting in a high-pitched noise. Most modern AC adapters are switched-mode power supplies.
@Ramhound Audible noise from a power supply does not imply noise in the electrical output. Most power conversion devices contains coils, such as transformers or inductors. These components use electromagnetism to convert AC mains power to low-voltage DC power.
Yup, that's perfectly normal. Basically the inverters that convert the DC battery power to AC power for your devices are noisy, and you're hearing either 60Hz hum or harmonics thereof. Sometimes you'll even hear fans spin up to keep the inverter circuits cool.
However, you generally can't do this easily on small wall chargers of the sort you mentioned without risking damage to the charger or exposure to potentially dangerous voltages. Ultimately, a whining noise isn't necessarily a sign of trouble in cheaper wall chargers when little or no power is being drawn from them.
In addition, in low or no-load situations, the PWM used to regulate voltage at the inverter stage will be at a low duty cycle creating a "spikey" output profile which is more prone to causing vibration in coils, and the transformer itself will tend to vibrate as well (see Daniel R Hick's answer below for more details).
