[Technical field to which the invention belongs]

 The present invention relates to a hands-free communication device of a mobile phone which enables a hands-free call by wirelessly connecting a mobile phone terminal and an earphone microphone.

[0002]

[Problems to be solved by the invention]

 The use of a mobile phone while driving a car can be extremely dangerous as a one-handed steering wheel, and the number of accidents due to this is increasing rapidly. Also, when talking while opening a document while traveling by train or car, talking while operating a computer, or talking while taking notes, it is very inconvenient if one hand is blocked because there is no desk. It is.

In such a case, if a plug is inserted into an earphone jack of a mobile phone terminal and an earphone microphone is connected, a hands-free call becomes possible. However, since this is a wired connection, the cord of the earphone microphone becomes entangled or wraps around the body, making it uncomfortable to use. Also, since the length of the cord is limited, it is necessary to always wear the mobile phone terminal on the body or keep it at hand. When the mobile phone terminal is kept close to the mobile phone terminal, the mobile phone terminal cannot be moved far away from the mobile phone terminal, and the movement is restricted.

Accordingly, the present invention has been made to enable a cordless hands-free call by connecting a wireless earphone microphone to a mobile phone terminal.

[Means for Solving the Problems]

 In order to achieve such an object, the present invention is configured as follows.

That is, the invention of claim 1 relates to a hand-free mobile phone in which one station of a wireless unit for performing two-way communication is connected to a mobile phone terminal and the other station is integrally provided with an earphone microphone. It is a communication device. The invention according to claim 2 is the hands-free communication device for a portable telephone according to claim 1, wherein the wireless unit is a 400 MHz band specified low-power wireless unit and is connected to the portable telephone terminal via an interface connector. A third aspect of the present invention is the mobile phone hand-free communication device according to the first aspect, wherein the wireless unit is an FM wireless unit and is connected to the mobile phone terminal via an earphone plug.

[0007]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a hands-free communication device for a mobile phone according to the present invention. In the hands-free communication device 1, one station A of the wireless unit 2 that performs two-way communication is connected to the mobile phone terminal 3, and the other station B is integrally provided with the earphone microphone 4.

The radio unit 2 includes transmitters 21 and 21 and receivers 22 and 22 at both stations A and B, and connects to antennas 24 and 24 via antenna duplexers 23 and 23 for simultaneous transmission and reception. .

When using the 400 MHz band specified low power wireless unit, the mobile phone terminal 3 is connected to the wireless unit 2 via an 18-pin interface connector 31 as shown in FIG. When using the FM wireless unit, the earphone plug 33 is inserted into the earphone jack 32 and connected to the wireless unit 2 as shown in FIG.

FIG. 4 is an overall view of the earphone microphone 4 embodying the present invention. The earphone microphone 4 is provided with left and right ear contact portions 42, 42 at both ends of a holding frame 41 for holding and holding the head. The holding frame 41 is formed of a soft and flexible material such as vinyl chloride, and houses the antenna 24 inside or inside. The left and right ear pads 42, 42 house the receiver 22 on the station B side and the speaker 43 as one body inside one side, and house the transmitter 21 on the station B side inside the other side. The transmitter 21 is connected to a microphone 45 attached to the tip of a support frame 44 that is rotatably erected on the earpiece 42. Further, a lithium battery (not shown) is provided in one of the left and right ear pads 42, 42.

The hands-free communication device for a mobile phone according to the present invention is configured as described above, and connects the station A side of the wireless unit 2 via the interface connector 31 or the earphone jack 32 of the mobile phone terminal 3, and The headset is equipped with an earphone microphone 4 equipped integrally with the station B side of No. 2 to perform a cordless call.

[0013]

[Effect of the invention]

 As explained above. In the hands-free communication device of the mobile phone according to the present invention, one station of the wireless unit performing two-way communication is connected to the mobile phone terminal, and the other station is integrally provided with the earphone microphone. Therefore, according to the present invention, since the mobile phone terminal and the earphone microphone that is used by being worn on the head are cordlessly connected, both hands are free, and various operations can be performed while talking. In addition, since it is not a wired connection, the cord does not get in the way, it looks neat and the usability is good.
