摘要: A microphone and transmitter are mounted to a baseball base such that they do not interfere with the baseball game. The microphone senses audio data and the transmitter sends the audio data to a receiver. The receiver communicates the audio data to a mixer which can insert the audio data into a television or radio signal.
