Abstract

In recent years, a design where a microphone is not located in a position appropriately facing the oral cavity of an operator has been widely adopted from a viewpoint of convenience of miniaturization and mounting of a mobile telephone. When telephonic communication is made with such a mobile telephone, if a voice of the other party for telephonic communication is hard to hear, the operator necessarily tightly presses his/her face against a front surface of a chassis. Thus, the sensitivity and sound collecting property of the microphone are reduced. In the present invention, when a sound hole as a voice transmission path is formed in the vicinity of a manipulation section, slits are formed in the peripheries of the manipulation section and the sound hole. Hence, even in a situation in which an operator necessarily tightly presses his/her face against a front surface of a chassis, the voice transmission path is ensured to a certain extent, and thus the sound collecting property is ensured to some degree or more.

Claims (11)

1. A mobile telephone, comprising:

a chassis having a microphone, a manipulation section, a decorative mold, and a sound hole for voice transmission or sound collection provided near the decorative mold; and

slits provided in peripheries of the decorative mold and the sound hole,

said slits further including a slit which links the sound hole and the decorative mold to ensure voice transmission path,

wherein said manipulation section includes a plurality of keys, wherein a gap is provided in said chassis around at least one of said plurality of keys such that an opening to an interior of said chassis exists by way of said gap, and

wherein said slit which links the sound hole and the manipulation section provides for a voice transmission path to said microphone by way of said gap, said microphone being disposed within the interior of said chassis with said sound hole being provided above said microphone.

2. A mobile telephone according to claim 1 , wherein the chassis comprises:

a first chassis section that includes a display; and

a second chassis section that includes the microphone, the decorative mold, and the sound hole; and

a pivoting section provided between the first and second chassis sections, the pivoting section providing for the first and second chassis sections to be pivoted away from each other to allow a user to operate the mobile telephone, and providing for the first and second chassis sections to be pivoted towards each other so as to have respective inner surfaces of the first and second chassis sections contact each other in order to protect the mobile telephone when not in use,

wherein the slits are only provided on the inner surface of the second chassis that faces the inner surface of the first chassis when the first and second chassis sections are pivoted towards each other.
