Condenser microphone and method for manufacturing the same

A condenser microphone comprising a condenser microphone unit and an output module section provided with a circuit board for producing sound signals in a shield case, the condenser microphone unit being supported on the output module section via a support pipe including a flexible pipe, and the condenser microphone unit and the circuit board being electrically connected to each other via a microphone cable having a shield covered wire inserted through the support pipe,

• wherein the microphone cable is inserted through the support pipe in a state in which the shield covered wire having no skin is exposed throughout the entire length thereof, and in the predetermined portion of the shield covered wire, an elastic linear body which is formed by plantingly providing fibers in the radial direction around a core wire and has elasticity in the radial direction due to the fibers is provided along the microphone cable, whereby the predetermined portion of the shield covered wire is pressed against the inner surface of the support pipe by the elastic linear body.

• wherein the microphone cable is inserted through the support pipe in a state in which the shield covered wire having no skin is exposed throughout the entire length thereof, and around the predetermined portion of the shield covered wire, a spacer which holds the shield covered wire in a noncontact state with respect to the support pipe is provided.

A method for manufacturing a condenser microphone comprising a condenser microphone unit and an output module section provided with a circuit board for producing sound signals in a shield case, the condenser microphone unit being supported on the output module section via a support pipe including a flexible pipe, and the condenser microphone unit and the circuit board being electrically connected to each other via a microphone cable having a shield covered wire inserted through the support pipe,

• wherein after the microphone cable has been made in a state in which the shield covered wire having no skin is exposed throughout the entire length thereof, and has been inserted through the support pipe by applying an expandable ink material the volume of which is increased by heating to around the predetermined portion of the shield covered wire, the expandable ink material is heated to increase the volume thereof, by which the predetermined portion of the shield covered wire is held in a noncontact state with respect to the support pipe.
