The present invention relates to the function of the pager (wireless pager) to be implemented in the car audio, and in particular, by providing an interface means for transmitting the signal of the wireless pager, when connected to the jack terminal provided in the car audio on this interface, The present invention relates to an interface for outputting a pager sound with audio so that the function of the pager can be realized in audio.

In general, a wireless pager for remotely calling a remote person is shown in Figure 1, the receiving circuit unit 2, the microcomputer (3), the LCD display unit (4), the code decoder unit connected to the receiving antenna (1) (5). It consists of a speaker 6 and vibration means.

When the caller configured as described above calls the pager with a specific number, the caller receives the call signal through the reception antenna 1 and the reception circuit unit 2 of the pager, and the signal is transmitted to the microcomputer 3. At this time, the microcomputer 3 displays the call originating telephone number on the LCD display unit 4 and provides a predetermined signal to the code decoder unit 5 to call the caller to the mobile user through the speaker 6 and the vibration means. Let them know.

Therefore, the call signal is transmitted to the mobile caller regardless of the location of the caller, so that the call signal is transmitted.

In particular, in this case, the mobile phone does not recognize the detection of the ringing tone, such as a ringing tone while the earphone is put in the ear to listen to the mini-cassette, or when the pager cannot detect the vibration of the pager due to the vibration of the car itself. It exists.

The present invention has been made in order to solve the above-mentioned problems, by providing an interface means for transmitting a signal of a wireless pager, when connected to the jack terminal provided in the car audio on the interface, the call sound of the wireless pager in the car audio It is an object of the present invention to provide an interface for outputting a paging sound to a car audio that can be realized.

The present invention for achieving the above object is a wireless pager, which is provided to receive a predetermined signal from the microcomputer and outputs the ringing tone to the output means through the code decoder unit, the wireless pager provided to withdraw the ringing tone signal of the pager to the outside; An out terminal, a radio pager terminal provided to transmit a signal through the pager terminal, and a radio interface configured with a cable to electrically connect the pager terminal and the pager terminal. It is characterized in that the ringing tone of the pager is transmitted to the car audio.

In addition, the present invention is connected to the wireless pager terminal of the car audio receives the signal of the pager and the overall control of each peripheral device, the LCD display unit for displaying the calling party number under the control of the microcomputer, A drive for driving a speaker and a speaker connected to an output terminal of the drive and the microcomputer to output a voice may be provided in a car audio to implement a function of a wireless pager in the car audio.

In addition, the present invention has another feature such that a switch for determining whether to perform a micom function for driving the LCD display unit or to output the speaker immediately by the user's selection is further provided.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a block diagram in which the pager and car audio of the present invention are connected by an interface, and FIG. 3 is a flowchart showing the operation of FIG.

As shown in FIG. 2, the wireless pager out terminal 10 for extracting a ringing tone signal to the outside of a pager that receives a predetermined signal from a microcomputer and outputs a ringing tone to an output means through a code decoder. ), An interface 40 comprising a cable for electrically connecting the pager out terminal 10 and the pager terminal 20 of the car audio 30 to each other, and to the interface 40. Whether to perform the micom function of driving the LCD display unit 33 by the user's selection of the signal transmitted to the pager terminal 20 and the wireless pager terminal 20 to be directly provided to the speaker 34. A switch 31 provided to determine whether to output or not, and an LCD display unit having the same function as the wireless pager is connected to the pager terminal 20 to receive a signal of a pager. A microcomputer 32 for controlling overall peripheral devices, an LCD display 34 for displaying a caller's telephone number under the control of the microcomputer 32, and a switch 31 to drive a speaker. And a speaker 34 which is connected to the output terminals of the drive 35 and the microcomputer 32 to output audio.

Referring to Figure 3 the present invention configured as described above will be described as follows.

This is a useful invention in the case where the situation in which the user is in a situation where the call signal is not recognized, especially when the wireless pager is vibrated while riding in a car.

That is, the portable terminal is connected to the wireless pager terminal 20 and the wireless pager terminal 10 provided in the car audio by using the interface 40, and the installation is completed. When the call signal is received, the call signal is input to the pager terminal 20 through the interface 40. At this time, if the mobile operator simply switches the switch 31 to the drive 35 stage to listen only to the output function, the caller is connected to the pager. The signal of the terminal 20 drives the drive 35, and the call sounds through the speaker 34 connected to the drive 35, thereby indicating that there is a call. Thus, the phone number stored in the pager can be obtained to recognize the call number.

Meanwhile, in the present invention, the LCD display unit 33 of the car audio is provided so that the call number can be read out. When the switch 31 is switched to the microcomputer 32, the input signal is transferred to the microcomputer and the microcomputer 32 Call number is sequentially displayed on the LCD display unit 33 according to the control of the user can check the call number even by looking at the LCD display of the car audio.

Here, the same effect as the above function can be obtained in the mini-cassette provided with a microcomputer, a jack terminal, an LCD display unit, and a speaker in addition to the car audio mentioned above.

As such, the present invention connects the terminal provided in the wireless pager and the jack terminal provided in the car audio to realize the call sound of the wireless pager in the car audio, thereby avoiding the existing disadvantage of not recognizing the call sound due to the vibration of the vehicle. There is.
