Speaker system and vehicle door
Disclosed is a speaker system including a first panel that is an outer plate of a vehicle door, a second panel disposed on a vehicle interior side of the vehicle door, a third panel disposed between the first panel and the second panel, a speaker unit that has a sound emitting surface for emitting a sound toward the vehicle interior and is mounted on the second panel or the third panel, a first coupling mechanism that couples a peripheral portion of the second panel to the third panel, and a second coupling mechanism disposed at a position nearer the center of the second panel than a position of the speaker unit in the plane of the second panel and configured to couple the second panel and the third panel in the plane at a position not overlapping with the speaker unit.
1. A speaker system, comprising:
a first panel that is an outer plate of a vehicle door;
a second panel on a vehicle interior side of the vehicle door;
a third panel between the first panel and the second panel;
a speaker unit on one of the second panel or the third panel, wherein
the speaker unit includes a sound emitting surface,
the sound emitting surface is configured to emit a sound toward a vehicle interior, and
the sound emitting surface has a circular shape as planarly viewed from the vehicle interior along a central axis of the speaker unit;
a first coupling mechanism configured to couple a peripheral portion of the second panel to the third panel; and
a second coupling mechanism at a position nearer a center of the second panel than a position of the speaker unit in a plane of the second panel, wherein
the second coupling mechanism is configured to couple the second panel and the third panel in the plane at a position not overlapping with the speaker unit, and
a distance between a center position of the second coupling mechanism and a center of the sound emitting surface, as planarly viewed from the vehicle interior along the central axis of the speaker unit, is not greater than three times a radius of the sound emitting surface.
2. The speaker system according to claim 1 , wherein each of the first coupling mechanism and the second coupling mechanism includes:
an insert on the second panel; and
a receiver on the third panel, wherein the receiver includes an insertion hole into which the insert is to be inserted.
3. The speaker system according to claim 2 , wherein at least one of the first coupling mechanism or the second coupling mechanism includes the receiver on a tip of a rod-shaped portion on the third panel.
4. The speaker system according to claim 2 , wherein at least one of the first coupling mechanism or the second coupling mechanism includes the insert on a tip of a rod-shaped portion on the second panel.
5. The speaker system according to claim 1 , wherein each of the first coupling mechanism and the second coupling mechanism includes:
an insert on the third panel; and
a receiver on the second panel, wherein the receiver includes an insertion hole into which the insert is to be inserted.
6. The speaker system according to claim 5 , wherein at least one of the first coupling mechanism or the second coupling mechanism includes the receiver on a tip of a rod-shaped portion on the second panel.
7. The speaker system according to claim 5 , wherein at least one of the first coupling mechanism or the second coupling mechanism includes the insert on a tip of a rod-shaped portion on the third panel.
8. The speaker system according to claim 1 , further comprising an elastic body, wherein
the elastic body is between a first surface of the second panel and a second surface of the speaker unit,
the first surface is on a third panel side of the second panel, and
the second surface is on a second panel side of the speaker unit.
9. A vehicle door, comprising:
a speaker system including:
a first panel that is an outer plate of the vehicle door;
a second panel on a vehicle interior side of the vehicle door;
a third panel between the first panel and the second panel;
a speaker unit on one of the second panel or the third panel, wherein
the speaker unit includes a sound emitting surface,
the sound emitting surface is configured to emit a sound toward a vehicle interior, and
the sound emitting surface has a circular shape as planarly viewed from the vehicle interior along a central axis of the speaker unit;
a first coupling mechanism configured to couple a peripheral portion of the second panel to the third panel; and
a second coupling mechanism at a position nearer a center of the second panel than a position of the speaker unit in a plane of the second panel, wherein
the second coupling mechanism is configured to couple the second panel and the third panel in the plane at a position not overlapping with the speaker unit, and
a distance between a center position of the second coupling mechanism and a center of the sound emitting surface, as planarly viewed from the vehicle interior along the central axis of the speaker unit, is not greater than three times a radius of the sound emitting surface.
