Abstract

PURPOSE:To obtain easily a bibbon-type diaphragm featuring the excellent characteristics as a whole by using Be featuring the excellent characteristics in every point for the diaphragm itself and Al featuring elastisity for the edge part respectively. CONSTITUTION:Diaphragm base 10 which is the original form of the diaphragm is produced by the Al plate. In this case, flat vibration evaporation part 11 is formed at the middle part, and edge part 2 containing corrugate 2a and clamp part 3 extending over part 2 are formed in a body across part 11. Then only part 11 of base 10 is exposed, and other areas are covered with shadow mask 20. And Be is coated only at part 11 in the vacuum evaporation tank to use this part as vibration part 1. After this, resist layer 12 is applied on both surfaces at both-end part 1a through part 3, and Al plate 10 is removed at part 1 by etching. And the layer 12 is removed to from a ribbon-type diaphragm. In such way, the reality can be increased at the reproduction band, at the same time producing no undesired radiation.
