Abstract

A rucksack is provided which is equipped with a speaker system which creates, at a periphery of each ear of a rucksack carrier, a sound field in which sounds from an electric acoustic device can be heard clearly and naturally without use of headphones or earphones, and ambient noise as well can be heard clearly. A speaker unit, which radiates plane waves toward ears or vicinities of ears of the rucksack carrier, is disposed at a shoulder belt of a rucksack. The speaker unit is connected to a music playback device or the like accommodated in an accommodating portion of the rucksack.

Claims

1. A rucksack of a structure in which a rucksack main body is carried on a back by a shoulder belt, the rucksack comprising:

a speaker provided at the shoulder belt, the speaker making outputted sounds reach an ear of a rucksack carrier; and

an accommodating portion provided at at least one of the rucksack main body and a rucksack structural member connected to the rucksack main body, the accommodating portion accommodating an acoustic signal generating device connected to the speaker.

2. The rucksack of claim 1, wherein the speaker is a planar speaker having a planar diaphragm.

3. The rucksack of claim 1, wherein the speaker is provided so as to be movable along the shoulder belt.

4. The rucksack of claim 2, wherein the speaker is provided so as to be movable along the shoulder belt.

5. The rucksack of claim 1, wherein a speaker for low tones, which has a diaphragm having an area larger than an area of a diaphragm of the speaker provided at the shoulder belt, is provided at at least one of the rucksack main body, the shoulder belt, and the rucksack structural member connected to the rucksack main body.

6. The rucksack of claim 2, wherein a speaker for low tones, which has a diaphragm having an area larger than an area of a diaphragm of the speaker provided at the shoulder belt, is provided at at least one of the rucksack main body, the shoulder belt, and the rucksack structural member connected to the rucksack main body.

7. The rucksack of claim 3, wherein a speaker for low tones, which has a diaphragm having an area larger than an area of a diaphragm of the speaker provided at the shoulder belt, is provided at at least one of the rucksack main body, the shoulder belt, and the rucksack structural member connected to the rucksack main body.

8. The rucksack of claim 4, wherein a speaker for low tones, which has a diaphragm having an area larger than an area of a diaphragm of the speaker provided at the shoulder belt, is provided at at least one of the rucksack main body, the shoulder belt, and the rucksack structural member connected to the rucksack main body.

9. The rucksack of claim 3, wherein the shoulder belt has a mechanism for one of accommodating and holding a control instrument of the acoustic signal generating device.

10. The rucksack of claim 4, wherein the shoulder belt has a mechanism for one of accommodating and holding a control instrument of the acoustic signal generating device.

11. The rucksack of claim 5, wherein the shoulder belt has a mechanism for one of accommodating and holding a control instrument of the acoustic signal generating device.

12. The rucksack of claim 6, wherein the shoulder belt has a mechanism for one of accommodating and holding a control instrument of the acoustic signal generating device.

13. The rucksack of claim 7, wherein the shoulder belt has a mechanism for one of accommodating and holding a control instrument of the acoustic signal generating device.

14. The rucksack of claim 8, wherein the shoulder belt has a mechanism for one of accommodating and holding a control instrument of the acoustic signal generating device.

15. The rucksack of claim 11, wherein the shoulder belt has a mechanism for one of accommodating and holding a microphone.

16. The rucksack of claim 12, wherein the shoulder belt has a mechanism for one of accommodating and holding a microphone.

17. The rucksack of claim 13, wherein the shoulder belt has a mechanism for one of accommodating and holding a microphone.

18. The rucksack of claim 14, wherein the shoulder belt has a mechanism for one of accommodating and holding a microphone.
