Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hands-free device for a mobile phone.More specifically, a hook-type earphone microphone that can be hung on an ear receives a signal from a fixed case holder into which the mobile phone is inserted and receives a signal by wireless radio wave communication. , Can be transmitted.

[0002]

[Prior art]

 In general, mobile phone hands-free devices are often used in automobiles, and in this case, a holder for mounting the mobile phone is provided beside the driver's seat of the automobile. The holder is provided with a plurality of cords for connecting to a vehicle power supply and an antenna, whereby power required for the mobile phone is supplied from the vehicle power supply, and the mobile phone antenna is provided by the vehicle antenna. The transmission / reception range of the transmitting and receiving antennas is expanded. Therefore, the mobile phone can receive a relatively strong radio signal, thereby improving the quality of transmission and reception.

However, in such a mobile phone hands-free device mounted on a vehicle, a plurality of cords need to be connected to a power source, an antenna, and a mobile phone body of the vehicle. Connection of these cords and installation of the holder. Therefore, such mounting work cannot be easily performed, and the cost is high. Furthermore, removing a part of the interior of an automobile means that it also damages a part of the interior, which is not desirable. Also, most hands-free mobile phone devices are connected by cords, and the signal input / output terminal of the earphone is directly inserted into the input / output terminal of the mobile phone. However, since the connection was made by a cord, the signal line was inevitably obstructed in use, and the signal line was liable to be broken and lacked convenience.

[0004]

[Problems to be solved by the present invention] In view of the above problems, the present invention can be easily used without damaging the interior of a car, and can be used for hands-free listening while driving a car or a motorcycle. An object of the present invention is to provide a hands-free device for a mobile phone that can use the mobile phone safely because it can transmit a call.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments will be described in detail with reference to the drawings. FIG. 1 is an embodiment diagram of an earhook type earphone microphone according to the present invention. FIG. 2 is an embodiment view of the fixed case holder according to the present invention. FIG. 3 is a sectional view taken along line AA in FIG. FIG. 4 is an embodiment diagram in which the fixed case holder according to the present invention uses a rechargeable battery as a power source.

[0007]

【Example】

 As shown in FIG. 1, the hook-type earphone microphone 1 has a built-in battery-operated wireless electric circuit 14 and includes an earphone hook 11 and a telescopic transmission microphone 12. An earphone speaker 13 for receiving a voice signal from a mobile phone is provided at an appropriate position of the hook type earphone microphone 1. The telescopic transmission microphone 12 can be adjusted to an optimum position by expanding and contracting. With such a structure, the hook-type earphone microphone 1 attached to the user's ear can transmit and receive wireless telephone signals by combining the portable telephone with the externally connected radio signal transmitter 28. .

As shown in FIG. 2, the fixed case holder 2 mainly includes a seat 21 for holding the mobile phone 5, and the fixed case holder 2 is held at an appropriate place on the back of the seat 21. A clip 22 to be fixed is provided. Further, if the vehicle power supply plug 3 is inserted and connected to the vehicle power supply socket 23 which is also provided at an appropriate position on the back of the seat body 21, the power supply of the vehicle can be obtained. Further, since the household power supply socket 23 is provided on the side surface of the seat body 21, if the household power supply plug 4 is inserted and connected thereto, power can be obtained from a general household power supply.

In addition, as shown in FIG. 3, a space for accommodating the rechargeable battery 25 is provided below the seat body 21 in case electric power cannot be obtained from a car or a general household power supply. The power source to be used can be selected from the power source of the automobile, the power source for home use, and the rechargeable battery by the changeover switch 26 provided on the side of the seat 21. The radio signal transmitter 28 provided below the seat 21 is for transmitting and receiving signals of the mobile phone 5.

As can be seen from the above description, the hands-free device for a mobile phone according to the present invention uses the mobile phone 5 stored in the fixed case holder 2, and in this case, the plug 27 of the fixed case holder 2 is used for the mobile phone. The power supply is selected by the changeover switch 26 of the fixed case holder 2 and the reception and transmission are performed with the hook-type earphone microphone 1 mounted.

In addition, since the present invention employs wireless radio signal communication, it is possible to make a call without having to hold a telephone by hand even while driving a car or a motorcycle.

[0012] The above-described device is an example using the embodiment, and should not be interpreted in a limited manner. The device can be used in any scene such as when riding a bicycle, walking, or jogging. It is possible.

[0013]

[Effect of the invention]
