Abstract

A playback device including: a housing: an attachment portion to a first position on an attachment surface; a speaker that plays back sound in a predetermined direction in accordance with a first audio signal having a first band; and a vibration portion that vibrates in accordance with a second audio signal having a second band that is lower than the first band, the vibration portion having an abutment surface that abuts at a second position on the attachment surface. The attachment member, the speaker, and the vibration portion are attached to the housing.

First claim

The invention claimed is:

1. A playback device comprising:
a housing;
an attachment portion that is attached to a first position on an attachment surface;
a speaker that plays back sound in a predetermined direction in accordance with a first audio signal having a first band;
a vibration portion that vibrates in accordance with a second audio signal having a second band that is lower than the first band, the vibration portion having an abutment surface that abuts at a second position on the attachment surface; and
a notch, having a shape corresponding to a shape of the vibration portion, formed in a bottom surface of the housing, wherein the vibration portion is attached to the notch and disposed in a predetermined space,
the attachment portion, the speaker, and the vibration portion being attached to the housing.

2. The playback device according to claim 1 , wherein the attachment surface is a surface of a dashboard of a vehicle, and the speaker plays back sound toward a windshield of the vehicle.

3. The playback device according to claim 1 , wherein the first position and the second position are proximate to each other on the attachment surface.

4. The playback device according to claim 1 , further comprising:
a cable connected to the vibration portion,
wherein the abutment surface of the vibration portion abuts at the second position which is remote from the first position.

5. The playback device according to claim 4 ,
wherein the first position is a center portion of a surface of a dashboard of a vehicle, and
the second position is a portion of the surface of the dashboard of the vehicle in the vicinity of a housing space formed in the dashboard.

6. The playback device according to claim 5 ,
wherein the second audio signal is amplified by the housing space before being played back.

7. The playback device according to claim 4 , wherein the cable is retractable into the housing.

8. The playback device according to claim 1 , further comprising: an adjustment portion that adjusts a position of the abutment surface.

9. The playback device according to claim 1 , wherein the vibration portion is displaced in accordance with a stress applied from the attachment surface when the abutment surface abuts at the second position.

10. The playback device according to claim 1 , further comprising: a control section that supplies the first audio signal to the speaker and the second audio signal to the vibration portion.

11. The playback device according to claim 10 , wherein the control section generates the first audio signal and the second audio signal by performing predetermined signal processing on an audio signal supplied from a portable terminal.

12. The playback device according to claim 1 , wherein the housing is removably attached to the attachment portion.

13. The playback device according to claim 1 , wherein the predetermined space corresponds to an inner space between the notch and the upper surface of the housing.

14. The playback device according to claim 1 , wherein the abutment surface abuts the attachment surface via the notch.

15. A playback device comprising:
a housing;
an attachment portion that is attached on an attachment surface at a first position;
a speaker that plays back sound in a predetermined direction in accordance with a first audio signal having a first band;
a vibration portion that vibrates in accordance with a second audio signal having a second band that is lower than the first band, the vibration portion having an abutment surface that abuts at a second position on the attachment surface; and
a notch, having a shape corresponding to a shape of the vibration portion, formed in a bottom surface of the housing, wherein the vibration portion is housed in the notch and a predetermined space in the housing.
