Abstract: A lavalier microphone assembly wherein ambient and mechanical interference are minimized. The assembly comprises a lavalier microphone. The microphone includes a microphone casing having an aperture for the entry of sound waves and a transducer disposed within the casing near the aperture for conversion of sound waves into electrical signals. The assembly also comprises a cable, which is connected to the transducer for transmitting the electrical signals to a remote location for processing. The assembly further comprises a microphone cage which is attached to the cable and which surrounds the microphone. By surrounding the microphone, the cage both prevents the microphone from being inadvertently contacted and spaces the microphone from noises produced by the rustling of clothing. The cage is mounted on an article of clothing by means of a mounting pin, the mounting pin being fixedly mounted on the cage.
