    摘要: The invention relates to a dynamic loudspeaker driver (42) which comprises a magnet-system (42), a membrane and a voice coil (45). The membrane comprises a semi-rigid diaphragm (43) and a flexible annulus (44) surrounding the diaphragm (43). The diaphragm (43) is movably mounted with respect to the magnet-system (42) by means of the annulus (44) and comprises a substrate (50) which comprises a first surface (51) and a second surface (52) being opposite to the first surface (51), a first layer (61) attached to and continuously covering the first surface (51), and a second layer (62) attached to and covering the second surface (52). The second layer (62) comprises a plurality of holes (63) having a predefined pattern. The voice coil (45) is attached to the diaphragm (43) and is operatively coupled with the magnet-system (42).
