Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone strap having an antenna function and a mobile phone having the same.

[0002]

2. Description of the Related Art Conventionally, an antenna for a mobile phone is housed inside a housing of the mobile phone except for its tip. Especially when using a mobile phone, enhance the antenna function by pulling this antenna out as needed,
It is intended to make it easy to catch radio waves and make comfortable calls.

Such an antenna is generally composed of a coil, a tip for accommodating the coil, and a rod-shaped support for supporting the tip. The rod-shaped support is made of a metal wire for electrically connecting the coil to the mobile phone main body and a plastic material for protecting the metal wire, has relatively high hardness and elasticity. ing.

[0004]

Such a conventional antenna is excellent in that it can be pulled out of the housing and straightened out due to its hardness and elasticity and is hard to be damaged. This is inconvenient in that it must be withdrawn from the body (Problem 1). In addition, when making a call using a mobile phone, there is also a problem that an antenna that extends straight obstructs a caller (problem 2).

Further, when the cellular phone is not used, only the tip of the antenna is outside the housing and the support is housed in the housing. There is also a problem that the sensitivity of radio wave reception is poor.
In particular, when the mobile phone is stored in a bag, a pocket of clothes, or the like, reception is likely to be difficult (problem 3).

[0006] On the other hand, a strap is attached to a usual mobile phone, focusing on its convenience. Various types of straps are on the market, for example, a type formed by attaching a small doll to a colorful string-shaped member, and a type that emits light in response to the reception of radio waves.

[0007] However, such a conventional strap,
In particular, it only satisfies the user's hobbies and interests, and is not useful for the functions of the mobile phone itself, that is, for receiving radio waves, receiving calls, and talking. Therefore, an object of the present invention is to solve the above-mentioned problems 1 to 3 and to provide a strap which has mainly contributed to a user's taste and taste to a function inherent in a mobile phone.

[0008]

Means for Solving the Problems In order to solve the above problems,
The present invention provides a mobile phone strap having an antenna function. It is effective that the mobile phone strap is formed of a string-shaped member. Further, it is effective that the string-like member incorporates a coil. Further, it is effective that the string-shaped member is composed of the coil and the coil protecting material.

[0009] Further, the mobile phone strap of the present invention comprises:
It is effective to have an attachment member for attaching the string-shaped member to a mobile phone, and to form a ring by fixing both ends of the string-shaped member with the attachment member. In addition, the present invention also provides a mobile phone having the above-mentioned mobile phone strap.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, the present inventor has solved the above-mentioned problems 1 to 3 of a conventional antenna for a portable telephone, and has also provided a strap which has exclusively contributed to the taste and taste of the user. As a result of intensive research on whether a new function that can supplement the original function of a mobile phone can be provided, a mobile phone strap having a more convenient and excellent antenna function has been completed.

Hereinafter, a strap for a mobile phone having an antenna function according to the present invention will be described with reference to the drawings, but the present invention is not limited to these.
FIG. 1 is a schematic perspective view of one embodiment of a mobile phone strap according to the present invention. As shown in FIG. 1, a mobile phone strap 1 of the present invention includes a cord-like member 2.

The string-like member 2 has a built-in coil along its length, and is made of a coil protecting material for protecting the coil (not shown). The coil is not particularly limited as long as it is made of a material having conductivity sufficient to exhibit an antenna function, such as a metal coil used for a conventional coil.

The protective material for the coil is not particularly limited as long as it can protect the coil properly and has a certain strength so that the coil does not come out.
For example, a resin such as vinyl chloride may be used. However, in order to enable good reception of radio waves, it is necessary to appropriately control the thickness of the coil protection material, which depends on the material of the coil protection material and the power of the mobile phone. A trader can select as appropriate.

[0014] It is also possible to print a design or character according to the taste and taste of the user on the coil protection material. Further, it is also possible to manufacture the coil protection material from a colored material. In this regard, the mobile phone strap of the present invention also has the functions of the conventional strap.

Also, the mobile phone strap 1 of the present invention.
As shown in FIG. 1, the device further includes an attachment member 3 for attaching the string-shaped member 2 to a mobile phone, and both ends of the string-shaped member 2 are fixed by the attachment member 3 to form a ring. Is effective. When the strap has a ring shape in this way, the user's convenience of using the mobile phone is improved.

The mounting member 3 is made of metal for physically connecting the mobile phone strap 1 to the mobile phone main body and electrically connecting the coil portion to a circuit inside the mobile phone. It preferably has an external thread part 4. When the male screw portion 4 is provided, it is possible to remove the originally attached antenna and attach the mobile phone strap of the present invention to a conventional mobile phone that is commercially available.

The outside of the mounting member 3 may be covered with an electrically insulating material.
In addition to the above, it is effective to have the female screw portion 5. This is because the presence of the female thread portion 5 allows a conventional antenna to be further attached to this portion, thereby doubling the antenna function of the mobile phone.

[0018]

As described above, according to the mobile phone strap of the present invention, a mobile phone with an antenna function that enables good reception and reception of radio waves and realizes a comfortable call by the user of the mobile phone. A strap can be provided.
