<p>A microphone includes a head and a shank and a separation board is located between the head and the shank so as to define two chambers. The first chamber has a first transferring member and the second chamber has a second transferring chamber. The two transferring members each have a sound picking device. The two transferring members generate a signal simultaneously when the microphone is hit and the two respective signals are opposite to each other so as to be eliminated. Therefore, the microphone does not generate huge noise. <IMAGE></p> |
