PURPOSE:To facilitate the manufacture as well as increase the variety of the design for the microphone by using the microphone element protecting net which is continuous in the circumferential direction. CONSTITUTION:Microphone element protecting net 5 is formed flexibly by cutting crosswise and into the fixed length the long-size metallic mesh-type net woven into the cylindrical form featuring the seamless structure continuous in the circumferential direction. Then net 5 is extended once in the length direction to decrease the diameter and then inserted within support case 2 of the microphone. After this, the expansion is released by compression. As a result, net 5 is adhered close to the inner surface of case 2 to be then formed into protecting nets 6, 6a and 6b each of different shapes according to the shapes of case 2. |
