Abstract
An acoustic porting arrangement is provided that uses sound pressure signal ports (202, 112) to enhance speaker (406) and microphone cartridge (402) performance when mounting the speaker (406) on a moveable component, such as a flip part (102) of a flip-type cellular phone (100). A speaker acoustic path (504) is incorporated into the moveable component (102) to enhance the acoustic performance of an acoustic transducer (406). A microphone acoustic pathway (502) is also created through the moveable component (102) that delivers sound pressure energy to a microphone (402) that is mounted on a base (104) when the moveable component (102) is in its closed position and covering the microphone (108). Some embodiments reuse a surface acoustic port (202) for both paths.
