Abstract

A navigation apparatus 100 includes a current position information acquisition unit (a self-position acquisition unit 42) that acquires current position information, and a travel direction determination unit (for example, a route search unit 44) that determines a travel direction based on the acquired current position information and destination position information. The navigation apparatus 100 further includes a sound unit that outputs a sound (for example, a parametric speaker 30), and a sound control unit 41 that controls the sound unit so that the sound can be heard to the user from the travel direction.

Claims

1. A navigation apparatus comprising:

a current position information acquisition unit that acquires current position information;

a travel direction determination unit that determines a travel direction based on the acquired current position information and destination position information;

a sound unit that outputs a sound; and

a sound control unit that controls the sound unit so that the sound can be heard to a user from the travel direction.

2. The navigation apparatus according to claim 1,

wherein the sound unit is configured of a directional speaker, and

wherein the sound control unit forms a sound image of the sound using the sound unit in a position of the travel direction based on the user.

3. The navigation apparatus according to claim 2,

wherein the directional speaker is a parametric speaker.

4. The navigation apparatus according to claim 1,

wherein a position relationship detection unit that detects a relative position relationship between the user and the sound unit is further comprised, and

wherein the sound control unit controls the sound unit according to the relative position relationship detected by the position relationship detection unit.

5. The navigation apparatus according to claim 1,

wherein the sound control unit forms the sound image at an area within 30 cm based on the user'"'"'s ear.

6. The navigation apparatus according to claim 1,

wherein the navigation apparatus is a mobile terminal apparatus.

7. The navigation apparatus according to claim 1,

wherein the sound unit is configured of a plurality of speakers that are dispersed and arranged around the driver'"'"'s seat in a vehicle, and

wherein the sound control unit selectively outputs the sound from the speaker corresponding to the travel direction among the plurality of speakers.

8. The navigation apparatus according to claim 1,

wherein the sound control unit allows the sound unit output the sound for transmitting information except for information indicating the travel direction to the user.

9. The navigation apparatus according to claim 1,

wherein the travel direction determination unit determines a plurality of travel directions based on the current position information, and each position information of a plurality of destinations, and

wherein the sound control unit controls the sound unit so that the sound mutually different from each of the plurality of travel directions can be heard to the user at one time.
