[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on illustrated embodiments. FIG. 1 is an overall configuration diagram of a first embodiment of a headphone integrated navigation system according to the present invention. As shown in FIG. 1, this headphone-integrated navigation system includes a GPS main body 3 for inputting signals from a plurality of artificial satellites 1, and a GPS main body 3 connected to the GPS main body 3 and mounted on a user's head. And a headphone section 5. The GPS main unit 3 has an antenna 7, and the headphone unit 5 is used to support the left and right headphone speaker units 9 and 11 to be put on the user's ears and the headphone speaker units 9 and 11. A band unit 13; a microphone 15 for picking up a user's request instruction voice and an external environmental sound;
Microphone support member 17 for supporting the microphone 15
And FIG. 2 is an internal configuration diagram of the GPS main unit 3. As shown in FIG. 2, the GPS body 3 is
A GPS function unit 19 connected to the antenna 7, a CD-ROM 21 connected to the GPS function unit 19, a voice synthesis unit 23 connected to the GPS function unit 19, and a GPS unit connected to the GPS function unit 19 And a voice recognition unit 25. The voice synthesizer 23 is connected to the headphone speakers 9 and 11 via a first signal line 27, and the voice recognizer 25 is connected to the microphone 15 via a second signal line 29. Together with the third signal line 31
Are also connected to the headphone speaker units 9 and 11 via the. The CD-ROM 21 stores a large amount of map information.

Next, the operation of the headphone-integrated navigation system having the above configuration will be described with reference to the operation flowchart of FIG. First, step 101 in FIG.
In the above, when a user inputs a request for information on a place to be visited or a current position as navigation information to the microphone 15 by voice, an external environmental sound (a sound that can be heard at the place where the user is present) is generated together with the voice input. Microphone 1
5 (step 103). In step 105, the voice recognition unit 25 of the GPS main body 3
The input sound from the microphone 15 is transmitted to the second signal line 29
The voice input and the external environmental sound are separated from each other (step 107), and the external environmental sound is sent to the headphone speaker units 9 and 11 via the third signal line 31 as it is. The information is transmitted to the user (step 109), and the information of the voice input is recognized by voice (step 111). Here, as a method of the above-mentioned voice input, for example, "the place I want to go to is" No.- "of Denenchofu in Setagaya-ku, Tokyo or" Where is my current location? "
And so on.

Next, at step 113, the GP
The S function unit 19 refers to the signal from the artificial satellite 1 and the map information from the CD-ROM 21 in accordance with the recognized input information, and if the input voice is a place to go, information on the direction to go now. Is derived and output, and when the input voice is information on the current location, the current location information of the user is derived and output. Then, in step 115,
The outputted information on the direction to go now or the current position information (navigation information) of the user is output from the voice synthesis unit 2.
3 and is sent to the headphone speaker units 9 and 11 to be superimposed on the external environmental sound and transmitted to the user as voice (step 117).
The navigation information is output at any time according to the degree of movement according to the information from the antenna 7. Therefore, the user can always hear the external environmental sound together with the navigation information, so that the headphone speaker units 9 and 1 of the headphone unit 5 can be heard.
It is possible to avoid the danger caused by the inability to hear the external environmental sound even if the user touches both ears. In the voice recognition unit 25, the volume of the separated external environmental sound may be externally adjusted by an adjustment switch (not shown). As a second embodiment, as shown in FIG. 4, a single-ear type headphone in which the headphone speaker unit 9 is applied to only one ear may be used. In this case, since the external environment sound can be heard from the ears that do not touch the headphone speaker unit 9, the function of outputting the external environment sound to the headphone speaker 9 can be omitted. In the embodiments of FIGS. 2 and 4, a headphone of a type in which two audio output units are combined with a band-like band is shown.
In recent years, earphone-type headphones widely used in small cassette players and the like may be used.

Next, another embodiment of the above-described headphone integrated navigation system will be described with reference to FIG. FIG. 5 is a configuration diagram of another embodiment of a headphone integrated navigation system according to the present invention.
As shown in FIG. 5, in this headphone-integrated navigation system, the antenna 7 provided on the GPS main body 3 is provided on the upper end 33 of the band 13 of the headphone section 5. Fourth from the antenna 7 to the GPS function unit 19 of the GPS main unit 3
The received signal is transmitted by the signal line 35 of FIG. Other configurations and operations are the same as those of the embodiment shown in FIG. According to the other embodiment, the antenna having a shape protruding to the outside can be removed from the GPS main body 3, so that the GPS
The handling of the S body 3 becomes easy. Note that the antenna 7 is added to the headphone unit 5, but since it is provided at the upper end 33 of the band unit 13 as shown in FIG. Therefore, the antenna sensitivity also increases. As a second embodiment, as shown in FIG. 4, a single-ear type headphone in which the headphone speaker unit 9 is applied to only one ear may be used. In this case, since the external environment sound can be heard from the ears that do not touch the headphone speaker unit 9, the function of outputting the external environment sound to the headphone speaker 9 can be omitted.

[0009]

As described above, according to the present invention, since the headphone integrated navigation system is used, both hands can be used freely, portability is improved, and visual confirmation work is not required. Even disabled people can use it easily. In addition, since the external environment sound is picked up by the microphone and the navigation information is output to the user's ear by superimposing the sound on the external environment sound, there is no danger even if both ears are blocked by the headphones.
