Abstract

A speaker device (100) includes a speaker unit (2) including a diaphragm (6); a windshield cover (3) covering the speaker unit and including a sound emitting unit (130) emitting a sound produced by the speaker unit; and a cabinet (5) connected to a bottom of the windshield cover, and supporting the speaker unit so as to form an angle equal to or greater than 0 degree and equal to or smaller than 90 degree between a vibration direction X of the diaphragm and the sound emitting unit.

Claims

1. A speaker device used while attached to a mobile body, comprising:

a speaker unit including a diaphragm;

a windshield cover including an upper surface formed without an opening and covering the speaker unit so as to block air flowing for the speaker unit when the mobile body moves, and including a sound emitting unit emitting a sound produced by the speaker unit to an outside; and

a cabinet connected to a bottom of the windshield cover, and supporting the speaker unit so as to form an angle equal to or greater than 0 degree and equal to or smaller than 90 degree between a vibration direction of the diaphragm and a sound emission surface formed by the sound emitting unit.

2. The speaker device according to claim 1, wherein a surface of the windshield cover on which the windshield cover faces the speaker unit is convex toward the diaphragm.

3. The speaker device according to claim 1, further comprising a vent hole causing air to circulate between inside the windshield cover and outside of the speaker device.

4. The speaker device according to claim 3, comprising an air trunk provided to surround a side surface and a bottom of the cabinet and causing the air flowing around the speaker device to flow around the cabinet when the speaker device is moved.

5. A speaker device used while attached to a mobile body, comprising:

a speaker unit including a diaphragm;

a windshield cover including an upper surface formed without an opening and covering the speaker unit so as to block air flowing for the speaker device when the mobile body moves, and including a sound emitting unit emitting a sound produced by the speaker unit to an outside; and

a cabinet connected to a bottom of the windshield cover, and supporting the speaker unit so as to form an angle equal to or greater than 0 degree and equal to or smaller than 90 degree between a vibration direction of the diaphragm and a sound emission surface formed by the sound emitting unit, wherein the windshield cover includes a protrusion connected to a cabinet-side end of the sound emitting unit and inclined to be located outward of a surface formed by the sound emitting unit.

6. The speaker device according to claim 5, wherein a surface of the windshield cover on which the windshield cover faces the speaker unit is convex toward the diaphragm.

7. The speaker device according to claim 5, further comprising a vent hole causing air to circulate between inside the windshield cover and outside of the speaker device.

8. The speaker device according to claim 7, comprising an air trunk provided to surround a side surface and a bottom of the cabinet and causing the air flowing around the speaker device to flow around the cabinet when the speaker device is moved.

9. An installation body for installing and supporting a speaker device, the speaker device comprising:

a speaker unit including a diaphragm;

a windshield cover covering the speaker unit and including a sound emitting unit emitting a sound produced by the speaker unit to outside; and

a cabinet connected to a bottom of the windshield cover, and the installation body comprising;

a concave portion away from the cabinet at a predetermined distance, wherein a space formed between the cabinet and the concave portion functions as an air trunk causing air flowing around the speaker device when the installation body installed with the speaker device is moved.

10. The installation body according to claim 9, comprising a support attached to the concave portion while being bonded to the concave portion, wherein the air trunk is formed between the cabinet and the support.

11. The installation body according to claim 9, comprising a support provided in the concave portion while being bonded to the cabinet, wherein the air trunk is formed between the cabinet and the concave portion.

12. The installation body according to claim 9, wherein the installation body is a trunk of a mobile body.

13. A mobile body on which the installation body according to claim 9 is mounted.
