Abstract
Improved microphonic capsule, characterized essentially by being constituted from an annular support piece to which the front and the rear case of the capsule are attached, which is at a certain distance from the support piece to determine a chamber occupied by foam material that together with holes in correspondence of such a support piece and the active membrane help to improve the acoustic response of the capsule, said active membrane being fixed to the central contact by riveting by means of fins determined in the periphery thereof and which also embrace the front membrane closing of the coals.
