The receiver 1, the microphone 2, the operation unit, and the LCD are installed on the surface.

[0003] Hereinafter, each part of the conventional portable telephone will be described in detail. The receiver 1 is a speaker that emits a received audio signal, and is usually provided on an upper part of a mobile phone. The microphone 2 picks up a voice uttered by the user and converts it into an electric signal, and is usually provided at a lower part of the mobile phone. In addition, the operation unit and the LCD are both provided between the receiver 1 and the microphone 2 in a general mobile phone design.

[0004] A user uses a mobile phone by bringing the receiver 1 to the ear and holding the microphone 2 close to the mouth for talking.

[0005]

However, in the above-mentioned conventional portable telephone, a receiver and a microphone are arranged at an interval between an average user's ear and a mouth. However, there is a problem that the convenience cannot be reduced because the mobile phone cannot be brought close to the mouth sufficiently, and the height of the mobile phone cannot be reduced to a certain value or more, and the so-called straight type design cannot be downsized.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a portable telephone capable of freely adjusting the position of a microphone, having high convenience, and achieving downsizing.

[0007]

According to a first aspect of the present invention, there is provided a portable telephone, wherein a microphone can be pulled out of a main body of the portable telephone. It can be used by pulling it out to the desired position, and the microphone can be stored in other places to reduce the size of the main body.

According to a second aspect of the present invention, in a portable telephone, a microphone, a microphone line connected to the microphone, and a microphone line connected to the microphone when the microphone is pulled out from the main body. And a stopper for stopping the microphone at an arbitrary position, so that the microphone can be pulled out to a desired position for use during a call, and the microphone can be housed in other locations to reduce the size of the main body.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable telephone according to an embodiment of the present invention will be described with reference to the drawings. A mobile phone (this machine) according to an embodiment of the present invention draws or stores it in the manner of an outlet plug of a vacuum cleaner or the like, and has a lead wire (hereinafter, referred to as a “microphone wire”) having appropriate elasticity. The microphone is provided at the end thereof, whereby the position of the microphone can be appropriately adjusted, and if the microphone is housed, the size can be reduced.

[0010] As shown in FIG.
, An operation unit and an LCD on the main body side, and a microphone line 21 to be pulled out from the main body, and a microphone 20 at the end. FIG. 1 is an explanatory diagram illustrating the appearance of the present apparatus.

[0011] Each operation is the same as the conventional one,
The layout design is different. The receiver 1, the operation unit, and the LCD are installed on the surface, and the microphone 20 is installed at the tip of the microphone wire 21 drawn out from the lower part.

Here, a structure for extracting and storing the microphone wire 21 will be described with reference to FIG. FIG.
FIG. 3 is an explanatory diagram illustrating a structure for pulling out and storing a microphone wire. This structure, as shown in FIG.
2 and a stopper 23. Microphone line 2
1 is to cover the surface with, for example, rubber having a suitable elasticity, so that the overall shape is not easily deformed.
One having a metal wire as a core is conceivable.

By using the metal wire as the core, not only does the shape not easily deform, but also the position of the microphone 20 is fixed when the microphone 20 is pulled out, so that only the main body of the portable telephone is held with one hand. By merely bringing the receiver 1 close to the ear, it is not necessary to hold the microphone 20 with another hand, which has the effect of improving usability.

The microphone 2 has a microphone 2 inside.
An electric wire for transmitting an electric signal output as “0” is passing therethrough.
Therefore, one end of the microphone wire 21 is connected to the microphone 20,
The other end of the microphone line 21 is connected to a microphone amplifier circuit or the like for amplifying an electric signal.

The ladder 22 is supposed to be formed of a material such as plastic or metal which is not easily deformed, and serves as a line for accommodating the microphone wire 21. That is, the microphone wire 21 moves along the ladder 22.

The ladder 22 is accommodated in a housing of the mobile phone, and one end is exposed at a lower portion of the mobile phone.

The stopper 23 is a mechanism attached to one end of the ladder 22 that is exposed at the lower part of the portable telephone.
This is a mechanism for fixing the microphone wire 21 once pulled out at that stage so as not to be pulled out or pulled back further, and specifically, such as an outlet reel of a household vacuum cleaner or the like. A structure having the same structure as that of a stopper in an automobile seat belt is conceivable.

The stopper 23 prevents the microphone wire 21 from being pulled out from the ladder 22 completely so that it cannot be extended beyond a certain amount.

Next, the operation of the apparatus will be described. The user puts the receiver 1 against the ear and draws out the microphone wire 21 so that the microphone 20 is at an appropriate position in the mouth.

Then, the microphone line 21 slides down the ladder 22 and the microphone 20 is pulled out. When the user stops pulling out the microphone 20 at a certain place, the stopper 23 stops the microphone line 21 at that position.

Then, the user starts a call. At this time, the microphone 20 is suddenly pressed or the microphone 2 is pressed.
0 is pulled out, the stopper 23 is
Since 1 is stopped, the microphone 20 is not stored in the housing, and the microphone 20 is not completely pulled out and the mobile phone is not broken.

According to the present apparatus, the distance between the receiver 1 and the microphone 20 can be adjusted according to the user's preference, and the convenience can be improved. In addition, the microphone 20 is provided outside the main body. Therefore, the height of the housing can be shortened by the size of the microphone 20, so that there is an effect that downsizing of the housing can be promoted.

When the stopper 23 of the present apparatus is provided in the main body, if the microphone 20 can be housed without protruding into the main body and the microphone 20 can be easily pulled out, the microphone 20 is prevented from being damaged. The convenience can be improved.

More specifically, the stopper 23 is formed slightly behind the main body, and the microphone 20 is accommodated in the recessed space. Can be extracted.

[0025]

According to the first aspect of the present invention, the mobile phone is configured such that the microphone can be pulled out from the main body.
Otherwise, there is an effect that the microphone can be housed to reduce the size of the main body.

According to the second aspect of the present invention, since the microphone line connected to the microphone is pulled out of the main body and the microphone line is stopped at an arbitrary position by the stopper, the microphone is pulled out to a desired position during a call. Use
Otherwise, there is an effect that the microphone can be housed to reduce the size of the main body.
