A wearable device has a motion detector configured to detect motion of the device and produce a motion signal relating to motion of the device, a contact sensor configured to detect if the device is in contact with an object and produce a contact signal relating to whether the device is in contact with an object, and a controller operatively coupled with the motion detector and the contact sensor. The controller is configured to switch between on and off-states as a function of at least one of the motion signal and contact signal. The device also has a sound transducer or other transducer operatively coupled with the controller. The controller is configured to change the state of the sound transducer between on and off-states in response to receipt of the motion signal, and the contact signal.
