Description

A hands-free apparatus with an interrupt-generator by setting of a portable movie-telephone}

In the future, video mobile phones are expected to be widely used worldwide.

The present invention relates to an apparatus for using a video mobile phone while driving.

Hands-free use is increasing rapidly as the danger of using a mobile phone while driving is widely known. However, hands-free use does not use the hand when receiving, but still requires the use of the hand when making a call.

At one time, a mobile phone with voice recognition was used, but the words are too weak to be recognized and the words that can be recognized are extremely limited.

The present invention is a device that allows a driver to make a call without using his or her hand by setting up a separate service and a separate operator in a telecommunication company in case of a need for a hasty call due to an accident while driving. .

In the present invention, in addition to the existing microphone 25 and the speaker 28 to the hands-free device to call a separate service and operator to be permanently established in the communication company (send) switch 11 and the end of the video mobile phone (1) An interrupt generator 21 and an end switch 22 are provided at the hands free to replace the switch 12, so that the interrupt generator 21 of the hands free 2 is interrupted to the control unit 10 of the video phone 1. A device that allows the operator to connect the desired number and the mobile phone or the video mobile phone to the operator of a specific phone number stored in the memory unit 4 of the video mobile phone 1 by generating a. to provide.

Hands free switch device 24 and end switch 22 are hands free or decorative. In particular, it can be installed in a place easily accessible to the driver such as a steering wheel.

Referring to the configuration and operation of the present invention in detail.

1 is an overall block diagram of the present invention.

(1) is a block diagram of a conventional video mobile phone. The voice of the video mobile phone user entering the transmitter 5 is amplified by the voice transmission signal processing section 6 and the analog signal is converted into a digital signal. The received signal applied from the controller 10 is amplified by converting the digital signal into an analog signal by the voice received signal processor 7. The controller 10 includes a main controller and a baseband circuit. The human interface unit 9 is operated by a handset key input unit 13 including a send switch 11 and an end switch 12. The cover switch 14 turns on / off the connection between the handset 5 and the handset 8 and the power source 3. The memory unit 4 of the video mobile phone sends the built-in information to the control unit 10 or stores the information sent from the control unit. In the frequency synthesizer 17, the frequency is constantly changed to meet the needs of mobile phone base stations. The antenna 16 and the video and audio transmission / reception apparatus 15 transmit and receive according to the needs of the user of the video mobile phone 1.

The moving image input from the camera unit 42 is input to the interface unit 9 via the camera driver 41. The moving picture received through the antenna 16 and the video and audio transmission / reception device 15 is output to the (liquid crystal) monitor 44 via the interface unit 9 and the (liquid crystal) monitor driver 43.

(2) is an interrupt that allows the mobile phone to send an outgoing signal even when the hands-free end switch 22 and the cover switch 14 are closed so as to send an end signal in place of the end switch 12 to the video mobile phone 1; The hands free device of the present invention, to which the generator 21 is connected. The switch device 24 serves as a function key button for operating the interrupt generator 21. Connector 20 is a device for connecting the hands free (2) and the mobile phone (1), the connector 20 is configured to form a jack on one side to separate the hands free (2) and the mobile phone (1). The transmission signal processing unit 26 connected to the microphone 25 may be configured to use the transmission signal processing unit 6 of the mobile phone 1 instead, and may include amplifying devices, transmission attenuators, and coupling terminals, and a hands free center. Under the control of the processing apparatus 32. The reception signal processing unit 27 connected to the speaker 28 may be configured to use the reception signal processing unit 7 of the video mobile phone 1 instead, and may include amplifying devices, reception attenuators, coupling terminals, variable resistors, and levels. Comparators may be included and are controlled by the hands-free central processing unit 32.

The power supply of the hands-free device may be designed to use the power of the video mobile phone, and may use the hands-free power supply.

Embodiments using the present invention using the apparatus of the present invention above are as follows.

When you need to use the video phone while driving, leave the cover switch 14 as it is, and find and press the button of the switch unit 24 of the hands free (2) attached to the steering wheel or attached to the street or other places. The interrupt generator 21 is operated by connecting a power supply (battery) 35 to the interrupt generator 21. This signal generates an interrupt to the main control part of the control unit 10 through the connector 20 and the interface unit 9. The phone number stored in the memory unit 4 is dialed, and the video mobile phone user who is driving can talk to an operator of a telecommunication company that has been contracted in advance. The operator soon connects the driver's video phone with the number desired by the video phone user who is driving. When the call is finished, generally, the call is terminated by pressing the end switch 22 of the hands-free 2, or pressing the end switch 12 of the video stream phone 1 in case of failure or special case.

According to the present invention, the call switch 11 of the video mobile phone 1 in addition to the existing microphone 25 and the speaker 28 in the hands-free device so that the operator can call a separate service and operator to be permanently installed. And an interrupt generator 21 and an end switch 22 in the hands-free so as to replace the end switch 12 and the end switch 12, so that the interrupt generator 21 of the hands-free 2 controls the control unit 10 of the video phone 1. Interrupts are generated and connected to the operator of the specific telephone number of the telecommunications company stored in the memory unit 4 of the video mobile phone 1, so that the operator can connect the mobile phone or the video mobile phone with the number desired by the driver.

Instead of the operator, information may be pre-built in the memory unit 4 so as to be connected to a number such as a parent, a friend, or a wife of a lover.

The hands-free switch device 24 and the end switch 22 can be installed in a place that can be easily used by a driver, such as hands-free or a decoration, especially a steering wheel.

The interrupt generator 21 and the switch device 24 may be provided in the video mobile phone 1 to constitute a circuit.

A power cutoff switch may be used instead of the end switch 22.

As another embodiment of the present invention, when the cover switch 14 is closed, pressing the hands-free end switch 22 twice, the latest use number is displayed on the monitor of the video mobile phone 1 in order of recent use, A black selection mark appears over the (most recent) usage number, and pressing the end switch 22 again moves the selection mark over the next (next recent) usage number. At this time, when the switch device 24 for operating the interrupt generator 21 is pressed, the selected number and the call path are connected.

The effect of the present invention provides a device that allows a driver to make a call without using a hand by standing a separate service and a separate operator in the telecommunications company in case it is necessary to make a phone call urgently while driving. It is.

In addition to the existing microphone 25 and speaker 28 in the hands-free device, a call switch 11 and an end switch 12 of the video mobile phone 1 can be called to call a separate service to be permanently established by the telecommunication company. And an interrupt generator 21 and an end switch 22 in hands-free so that the interrupt generator 21 in the hands-free 2 generates an interrupt in the control unit 10 of the video mobile phone 1 The present invention provides a device that allows an operator to connect a mobile phone or a video mobile phone with a desired number of a driver by connecting with an operator of a specific telephone number of a telecommunication company stored in the memory unit 4 of the video mobile phone 1.
