    Abstract: The invention relates to a portable communication apparatus and a microphone device for the apparatus. In the portable communication apparatus of the invention, an openable/closable member (2) is attached in an openable and closable manner to a main unit (1) of the portable apparatus. The openable/closable member (2) incorporates a bidirectional close-talking microphone (5). An inner sound hole (26) and an outer sound hole (27) are opened in an inner wall (22) and an outer wall (24) of the openable/closable member (2), respectively. The inner wall (22) faces the front face of a diaphragm of the close-talking microphone (5) via a sound path (64), and the outer sound hole (27) faces the rear face of the diaphragm of the close-talking microphone (5) via a sound path (65). The inner sound hole (26) is biasedly located in a position which is close to a free end of the openable/closable member (2), and the outer sound hole (27) is biasedly located in a position which is close to the center position of opening and closing movements of the openable/closable member (2). The portable communication apparatus of the invention can obtain a speech quality of a very high S/N ratio at a substantially same degree in both the cases where the openable/closable member (2) is opened, and where the member is closed.

    Abstract: A flat panel speaker has a construction in which an actuator 10 vibrates a panel 21 to radiate sound, the panel 21 being held at a peripheral portion thereof on a frame 22 by gaskets, wherein the gasket 31 provided at a position opposite from a position at which the actuator 10 is placed has a higher hardness than that of the gasket 32 provided at another position. The side on which the gasket 31 having the higher hardness is placed is a substantially fixed end to facilitate vibration of the panel 21, thereby improving sound quality.
