Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone which has been widely used in recent years, and more particularly to a structure of a receiving section which can receive a receiving sound without being affected by surrounding noise even when the surroundings are noisy.

[0002]

2. Description of the Related Art An ordinary portable telephone is structurally structured such that a telephone case main body in which a communication electronic circuit capable of communicating by transmitting and receiving radio waves is built, and which is mechanically and electrically detachable from the electronic device case main body. It is roughly composed of a battery case main body containing a rechargeable battery that is attached and supplies power to the electronic circuit, a display unit that displays information in liquid crystal, and a plurality of keys that are switches.

[0003] Further, a transmission / reception mouthpiece is provided above and below a telephone case in which a display unit and a plurality of keys are installed. Since the mouthpieces installed above and below are mostly mobile phones, the mouthpieces of the mouthpieces are recessed from the plane part of the front surface, that is, recessed. In particular, if the earpiece is concave and the surrounding area is flat, the ears of the person are uneven, so it is difficult to adhere to this part and the surrounding noise enters and it is difficult to hear, and the earpiece matches the ear hole It is hard to hear because it is an invisible part.

[0004] For this reason, there is a structure in which the periphery of the earpiece is depressed and closely attached to the ear to prevent the intrusion of surrounding noise. However, similarly, the ear hole and the earpiece cannot be matched with each other. They cannot be sufficiently adhered. That is, in the case of a conventional earpiece, since the earpiece is concave, flat, or slightly exposed, the noise of the surroundings is caused to invade, so that it is difficult to hear the received sound.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to positively bulge the earpiece portion into a flat portion so that the earpiece can be inserted into an ear hole and adhere to the ear. It is an object of the present invention to provide a receiver structure of a mobile phone in which the hole of the earpiece can be made to coincide with the hole of the earpiece and the difficulty in hearing due to ambient noise can be eliminated.

[0006]

A means for solving the above-mentioned problem is that a mobile phone case body having a communication electronic circuit having an antenna extending outside and having a communication function for transmitting and receiving radio waves is provided. A battery case body detachably attached to the mobile phone case body and including a rechargeable battery for supplying power to the communication electronic circuit; a display device provided on a surface of the mobile phone case body to display information; A plurality of keys formed on the surface of the mobile phone case body electrically connected to the electronic circuit for use and performing various functions, a earpiece formed on the surface of the mobile phone case body and protruding from a flat portion, and the surface And a mouthpiece formed on the mobile phone.

[0007]

By making the earpiece positively bulging out of the surrounding flat part, the earpiece can be inserted into and adhered to the ear hole, so that surrounding noise does not enter and it becomes difficult to hear. Further, since the hole in the human ear is at most about 2 cm left and right, the area of swelling can be made closer by setting the left and right sides to about 2 cm.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings and FIG. 1. FIG. 1 is a perspective view of a mobile phone case main body.

Reference numeral 1 denotes a plastic mobile phone case body, in which a communication electronic circuit capable of communicating by transmitting and receiving radio waves is incorporated. Reference numeral 2 denotes a liquid crystal display for displaying various data. Reference numeral 3 denotes a plurality of switch function keys for inputting various functions, and letters, numerals, and pictograms are formed on the surface of the key 3.

Below the key 3, a mouthpiece 4 is formed so that speech can be sent. The liquid crystal display unit 2
The earpiece 5 is formed on the telephone so that the telephone can be received. The periphery of the earpiece 5 has a relatively wide flat structure, and a bulge 6 is formed in the flat structure. In other words, the bulging portion 6 is set at a height so as not to be too deep into the ear, protrudes from a flat portion, and the hole of the human ear is about 2 cm in length on the left and right sides. The bulging portion 6 is also formed with a width that satisfies this. Therefore, the bulging portion 6 can be in close contact with the ear hole, so that external noise hardly enters the ear. In addition, a hole of the earpiece 5 may be arranged at the center of the bulging portion 6 and may be slightly conically recessed around the hole. Thereby, it is possible to prevent dust or the like from directly adhering to the hole and closing the hole. The earpiece may have a plurality of holes.

[0011]

As described above, according to the present invention, a portable telephone case main body having a communication electronic circuit having an externally extended antenna and capable of communicating by transmitting and receiving radio waves is provided. A battery case main body which is freely mounted and includes a rechargeable battery for supplying power to the communication electronic circuit, a display device provided on a surface of the mobile phone case main body to display information, and an electric device for the communication electronic circuit. A plurality of keys formed on the surface of the mobile phone case main body, which are connected to the main body, and perform various functions; a receiver formed on the surface of the mobile phone case main body and bulging out from a flat portion; and a transmission formed on the surface. Since it is composed of the mouth, the bulging portion that has swelled positively can be inserted into the ear hole, and can be in close contact with the ear, so that the hole of the earpiece can coincide with the ear hole. Therefore, it is possible to provide a receiver structure of a mobile phone, which has an effect of eliminating the difficulty of hearing due to ambient noise.
