Abstract
This invention provides a phase plug for loudspeakers of the compression driver type having a body characterized by a plurality of channels, each channel constituting a wave passage for acoustic waves from an input surface (that receives acoustic waves) to an output surface (that transmits acoustic waves), the input surface being provided by an integral member. The positions and widths of the channel openings are determined in order to reduce acoustic resonances in the compression chamber. The acoustic channels are characterized by the fact that their openings towards the input surface depart in the axial direction. The width of the acoustic channels is computed in order to guaranteed that there will be no loss of acoustic intensity in the channels.
