Abstract

A sound system for a vehicle is provided, which includes as sound sources disposed at given positions of the vehicle, an engine and an audio device for an internal space of a cabin. The system includes an engine sound localizer configured to localize a first sound generated by the engine to cause a vehicle driver inside the cabin to hear the first sound from a first position, and an audio sound localizer configured to localize a second sound generated by the audio device to cause the driver to hear the second sound from a second position. The first and second positions are located forward of the driver in front-and-rear directions of the vehicle and separated from each other by a given distance.

First claim

What is claimed is:

1. A sound system for a vehicle including an engine and an audio device for an internal space of a cabin as sound sources disposed at given positions of the vehicle, comprising:
an engine sound localizer configured to localize a first sound generated by the engine to cause a vehicle driver inside the cabin to hear the first sound from a first position; and
an audio sound localizer configured to localize a second sound generated by the audio device to cause the driver to hear the second sound from a second position, wherein
the first and second positions are located forward of the driver in front-and-rear directions of the vehicle and separated from each other by a given distance,
the first position is located upward of the second position,
the vehicle includes an instrument panel and a front windshield extending upward from a front-end part of the instrument panel,
the first position is set in the front windshield,
the second position is set in the instrument panel, and
a panel opening is formed on an upper surface of the instrument panel such that the first sound is transmitted from the panel opening toward the front windshield and reflected to the vehicle driver.

2. The sound system of claim 1 , wherein
the engine is disposed in an engine bay formed forward of a dashboard defining a front end of the cabin, and
the dashboard is formed with a highly-sound-transparent section where transparency of the engine sound is higher than other sections.

3. The sound system of claim 2 , wherein the highly-sound-transparent section faces into the instrument panel, and the engine sound is localized to the first position via a space inside the instrument panel.

4. The sound system of claim 3 , wherein the highly-sound-transparent section has an opening formed in the dashboard and an air-sealing film covering the opening.

5. The sound system of claim 1 , further comprising an alarm sound localizer configured to localize an alarm sound for issuing an alarm to a person in the vehicle, to a third position that is near an extension of a driver's line of sight when the driver looks forward.
