Acoustic modules

A portable electronic device, comprising:

• a device housing including a first acoustic port;
• an acoustic module coupled to the device housing, the acoustic module comprising:
• a second acoustic port aligned with the first acoustic port and extending through a surface of the acoustic module,
• an acoustic component aligned with the second acoustic port;
• a waterproof membrane covering the second acoustic port,
• a screen element covering the second acoustic port and positioned between the waterproof membrane and the acoustic component,
• and
• a spacer element disposed between the waterproof membrane and the screen element, the spacer element defining an opening aligned with the second acoustic port, the spacer element creating a gap between the waterproof membrane and screen element sized to allow the waterproof element to vibrate and pass acoustic waves through the first and second acoustic ports,
• wherein a thickness of the spacer element is selected to allow the screen element to restrain movement of the waterproof membrane in the area of the second acoustic port.
