Description

Mobile phone with a microphone / earphone combined antenna {Mobile station with Antenna and Microphone / Earphone in one}

The present invention relates to a mobile phone, and more particularly, to a mobile phone having improved functionality for use by adding functions of an earphone and a microphone to an antenna.

In general, a mobile phone is a mobile communication device that enables communication through a wireless relay by a relay station. As shown in FIG. 1, a speaker 12 and a microphone 14 are usually provided in a main body 10 so that a transmission and reception unit is provided. It is composed of an integrated structure, and is used in a hands-free manner by being used in conjunction with a so-called hands-free device such as a headset (head set) 20 worn on a head.

Here, the headset 20 is composed of components such as a microphone 22 and earphones 24, and a head holder 26 for wearing the handset, the end of the connection cord 28 is a telephone By being connected to the main body 10, the microphone 22 and the earphone 24 allow the user to make a call without directly passing through the main phone main body 10.

Here, the headset 20 is detachably connected to the phone body 10 by a jack plug (jack & plug) method, according to the jack plug method, the plug at the tip of the connection cord 28 of the headset 20 is a telephone The plug contacts the terminal inside the jack by being inserted into the jack of the main body 10.

On the other hand, the telephone body 10 is provided with an antenna 30 for increasing the transmission and reception sensitivity, the antenna 30 and the whip (301) mounted to the telephone body 10 to be movable The head portion 302 is provided on the top of the whip portion 301 and protrudes to the outside of the telephone body 10.

The antenna 30 is used to pull out the whip 301 by pulling the head 302 during the call.

As described above, according to the related art, the mobile phone can be used in the hands-free manner through the headset 20, and the high transmission and reception sensitivity can be maintained through the antenna 30.

However, according to the related art, in order to use the mobile phone in a hands-free manner, it is necessary to carry a separate headset 20, which is inconvenient to carry. There is a problem that the transmission and reception sensitivity is lowered because the 30 is not exposed to the outside.

The present invention has been made to solve the above-mentioned conventional problems, and is a structure that can be attached to and detached from the telephone main body, connected by the telephone main body and the connection cord, the microphone is provided at one end thereof, the earphone is provided at the other end of the transmission and reception function And to provide a mobile phone equipped with an antenna that performs the antenna and microphone / earphone functions at the same time.

1 is a plan view showing the structure of a general mobile phone and hands-free mechanism associated with it.

2 is a perspective view showing the structure of a cellular phone according to an embodiment of the present invention.

3 is a state diagram of use of the cellular phone according to the embodiment of the present invention.

10: telephone body 40: antenna

42: earphone 44: microphone

50: connection cord 60: spring reel

62: ratchet 64: operation button

A mobile telephone provided to achieve the above object includes a telephone body, an antenna detachably mounted to the telephone body, earphones provided at one end of the antenna, a microphone provided at the other end of the antenna, the antenna and And a connecting cord for connecting the microphone / earphone to the main body, and an automatic winding means for automatically inserting the connecting cord into the main body of the telephone.

Here, the self-winding means has a structure that is elastically rotated by a circumferential spring therein, a spring reel to which the connection cord is wound, a ratchet for controlling the rotation of the spring reel, and an operation button for operating the ratchet.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 to 3, and the same reference numerals will be given to the same parts as in the prior art.

As shown in FIG. 2, the cellular phone according to the embodiment of the present invention includes a telephone body 10, an antenna 40 detachably mounted to the telephone body 10, and one end of the antenna 40. The earphone 42, the microphone 44 provided at the other end of the antenna 40, the connection cord 50 for connecting the antenna 40 and the microphone / earphone 42, 44 with the main body 10 ), And the connection cord 50 is automatically included in the automatic winding means to be inserted into the telephone body (10).

Here, the antenna 40 may be configured to be easily worn by attaching a fastening means such as an ear holder or a binding clip.

In addition, the self-winding means has a structure that is elastically rotated by a circumferential spring (not shown) inside the spring reel (60) to which the connection cord 50 is wound, and the rotation of the spring reel (60) It consists of a ratchet 62 for controlling and an operation button 64 for operating the ratchet 62.

According to the embodiment of the present invention as described above, when using a mobile phone in a hands-free manner, as shown in FIG. 3, the antenna 40 is removed from the telephone body 10, and then the earphone 42 is inserted into the ear. Worn in a manner, and through the microphone / earphones 42 and 44 provided at both ends of the antenna 40.

Here, when the antenna 40 is separated from the telephone body 10, the connection cord 50 is drawn out from the telephone body 10, the connection cord 50 is wound on the spring reel 60 of the elastic rotating mechanism By being pulled by the antenna 40 in a state where it is released while rotating the spring reel (60).

At this time, the spring reel 60 is rotated in the direction of tightening the built-in eddy spring, when the connection cord 50 is drawn out as necessary to stop the rotation of the spring reel 60, the spring reel by the operation of the ratchet 62 60 is fixed.

After the call is finished, the state of wearing the antenna 40 is released, and the antenna 40 and the connection cord 50 are inserted into the phone main body 10. In this case, the ratchet 62 is pressed by pressing the operation button 64. To release the fixed state of the spring reel (60). In this way, as the circumferential spring is released, the spring reel 60 is rotated so that the connection cord 50 is wound on the spring reel 60 so that the antenna 40 is pulled and mounted in the telephone body 10.

That is, according to the embodiment of the present invention, it is not necessary to carry a separate headset 20 (see FIG. 1) or the like in order to use the mobile phone in a hands-free manner, and when the phone body 10 is in a hands-free manner, the phone body 10 is worn on the garment. Since the antenna 40 is exposed to the outside even in the stored state, high transmission and reception sensitivity by the antenna 40 is maintained.

As described above, the mobile phone according to the present invention can be used in a hands-free manner without using a separate device such as a headset. When using the hands-free method, the antenna is drawn out of the main body of the phone due to its structural characteristics. It maintains the reception sensitivity and provides the advantages of ease of use and operational stability.
