Abstract

PROBLEM TO BE SOLVED: To improve the voice directivity and sound collection performance of a sender and to prevent mis-operation of a dial button by introducing a voice of a talker to a microphone through a plurality of holes formed in a case. SOLUTION: A case part 2 is integrated with a main body part 1 in the standby state (not in use), antennas 4, 5 are contained in the main body part 1. Then a setting button of a telephone number is covered by the case 2. In the case of making a speech (in use), the case 2 is extracted outside, then the integrated antennas 4, 5 are extracted to set a speech enable state. A plurality of holes 2A are made to the case 2 and the voice of the talker is led to a microphone through a plurality of the holes 2A made to the case 2. That is, the holes 2A are made to enhance the directivity of the voice in the case of transmission toward the microphone.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a portable telephone.

[0002]

2. Description of the Related Art Conventionally, in a portable telephone, an antenna is arranged at an upper part of the telephone and a microphone is arranged at a lower part.
The microphone had a structure in which the voice of the sender could enter directly.

[0003]

As described above, the conventional mobile telephone has a structure in which the voice of the sender is directly input to the microphone, and there is a problem in the directivity of the voice to the microphone. there were. Further, the setting button (dial button) of the telephone number is exposed, and there is a problem that the user suddenly touches an object or the like or is operated by mistake.

[0004] Further, there is a problem that there is a problem in collecting the voice of the sender due to the fixed interval between the transmitter and the receiver. SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned problems and to provide a mobile phone capable of improving the directivity and sound collecting performance of a voice of a sender and preventing erroneous operation of a dial button.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a portable telephone, comprising: a microphone disposed on a main body of the portable telephone; A cylindrical body formed with a plurality of holes which are sometimes arranged so as to be able to be pulled out, and a pair of fixed to the cylindrical body which are housed in the main body of the mobile phone during standby and are arranged so as to be able to be pulled out during a call. An antenna comprising a rod is provided.

Therefore, the voice of the caller can be guided to the microphone through the plurality of holes formed in the cylindrical portion,
It is possible to improve the directivity or sound collection of the sound to the microphone. In addition, during standby, the telephone number setting button is covered by the cylindrical portion, so that unexpected operation can be prevented and the waterproofness and dustproofness can be improved.

[0007]

Embodiments of the present invention will be described below in detail. FIG. 1 is a perspective view of a mobile phone during standby according to an embodiment of the present invention, FIG. 2 is a perspective view of the mobile phone during a call, and FIG. 3 is a schematic side view of FIG. In these figures, reference numeral 1 denotes a main body of the portable telephone (hereinafter simply referred to as a main body), 2 denotes a cylindrical portion, 3 denotes a microphone arranged on the main body side, and 4 and 5 fix to the cylindrical portion. An antenna consisting of a pair of rods;
7 is a liquid crystal display for displaying the telephone number of the call destination, etc.
Is a switch such as a hook-on, a hook-off or a power switch, and 9 is a telephone number setting button arranged on a lower plane.

Reference numeral 10 denotes a groove for accommodating the side surface of the cylindrical portion 2 so that the cylindrical portion 2 can be moved, and reference numeral 11 denotes a hole for accommodating the antennas 4 and 5. Therefore, during standby (when not in use), as shown in FIG.
The antennas 4 and 5 are housed in the main body 1. The telephone number setting button is covered by the cylindrical portion 2.

At the time of a call (at the time of use), the cylindrical antenna 2 is pulled out so that the integrated antenna 4,
5 is also pulled out to be in a use state in which a call can be made. Here, a plurality of holes 2 </ b> A are formed in the cylindrical body portion 2, and by forming these holes 2 </ b> A, the directivity of voice to a microphone at the time of transmission can be increased.

Also, when pulling out the cylindrical portion and the antenna during a call, it serves as a knob for pulling out the cylindrical portion 2. Further, two antennas 4 and 5 are provided, and the tubular body portion 2 is attached so as to pass over the two antennas. With this configuration, according to the present invention, (1) directing the voice of the caller to the microphone 3 through the plurality of holes 2A formed in the cylindrical portion 2 Properties or sound collecting properties can be improved.

(2) During standby, a telephone number setting button 9
Is covered by the cylindrical portion 2, it is possible to prevent unexpected operation and to improve waterproofness and dustproofness. Also, by providing the two antennas 4 and 5, a diversity system can be adopted, so that the reception characteristics can be improved.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

[0013]

As described above, according to the present invention, the following effects can be obtained. (1) It is possible to improve the directivity or sound collection of the sound to the microphone. (2) Unexpected operation of the dial button can be prevented, and the waterproofness and dustproofness can be improved.
