ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to a portable communication device in which a built-in microphone is provided inside a flap pivotally provided to a body.
(b) Related, Background Invention
FIG. 7
shows a portable communication device of a related, background invention, which can be used as a cordless telephone, a portable cellular phone, a personal handy-phone system, and so on. The portable communication device comprises a body “a,” a flap “b” pivotally provided on the body “a” to open and close with respect to the body, and a built-in microphone “c” provided inside the flap “b.”
As shown in
FIGS. 7 and 8
, the flap “b” of the communication device has such a dual structure that an interior flap “d” and an exterior flap “e” are combined together. A recess “f” is formed in the inner surface of the interior flap “d,” and the microphone “c” is fitted into the recess “f” through a microphone holder “g.” The microphone holder “g” is sandwiched between the interior flap “d” and the exterior flap “e,” so that the microphone “c” is securely held in the flap “b.”
A sound-collection hole “h” is formed at a substantially central portion of the recess “f” in the interior flap “d.”
In a case where the portable communication device having the foregoing configuration is to be carried, the flap “b” is closed so that the device becomes compact. Therefore, its portability is enhanced, and the flap “b” covers an operation section “i” of the body “a,” to avoid inadvertent actuation of the operation section “i.”
Further, when the portable communication device is in use, the flap “b” is opened to a position shown in
FIG. 7
which permits actuation of the operation section “i” and exposes the sound-collection hole “h” provided in the interior flap “b.” Thus, communication is possible under this state such that sound is transmitted to the microphone “c” via the sound-collection hole “h”.
However, with the portable communication device having the sound-collection hole “h” formed only in the interior flap “d,” sound cannot be collected through the sound-collection hole “h” while the flap “b” is closed, thus disabling communication.
SUMMARY OF THE INVENTION
The present invention has been conceived to solve such a drawback of the above-mentioned portable communication device, and an object of the present invention is to provide a portable communication device which enables communication while a flap is closed.
To accomplish the foregoing object, the present invention provides a portable communication device comprising a body; a flap pivotally provided to a body to be opened and closed relative to the body; a built-in microphone provided inside the flap; and sound-collection holes, respectively provided in interior and exterior flaps, for collecting sound into the microphone. Since sound can be collected into the microphone regardless of whether the flap is closed or opened, communication becomes feasible in either state.
In case where a decorative panel is attached to the outer surface of the exterior flap in order to enhance a aesthetic effect, a sound-collection hole is formed in the panel so as to collect sound into the microphone.
The present disclosure relates to the subject matter contained in Japanese patent application No. Hei. 9-196393 (filed on Jul. 8, 1997) which is expressly incorporated herein by reference in its entirety.
