Abstract

A wearable speaker includes: a pair of speaker boxes that are attached on both ends of an attached band; and a speaker unit and a passive radiator that are attached on each of the speaker boxes.

Claims

1. A wearable speaker, comprising:

a pair of speaker boxes that are attached on both ends of an attached band; and

a speaker unit and a passive radiator that are attached on each of the speaker boxes.

2. The wearable speaker according to claim 1, wherein

the attached band has a U-shape, and

the speaker unit is attached on a first surface of each of the speaker boxes that faces an outside with respect to an ear of a listener in an attached status in which the attached band is hung on a neck of the listener, and the passive radiator is attached on a second surface of each of the speaker boxes that faces an inside with respect to the ear of the listener in the attached status.

3. The wearable speaker according to claim 2, wherein

the speaker unit is attached on a position of the first surface that deviates forward from a center position in forward and backward directions based on the listener in the attached status, and the passive radiator is attached on a position of the second surface that deviates backward from the center position in the forward and backward directions based on the listener in the attached status.

4. The wearable speaker according to claim 2, further comprising

a sound guiding unit that converts a radiation direction of a sound reproduced from the speaker unit.

5. The wearable speaker according to claim 4, wherein

the sound guiding unit includes a sound guiding space that is connected with a sound radiation surface of the speaker unit, a wall unit that forms the sound guiding space, and an aperture unit that radiates the sound from the sound guiding space.

6. The wearable speaker according to claim 5, wherein

a part of the wall unit tilts from a front side to a back side.

7. The wearable speaker according to claim 6, wherein

the tilt of the wall unit includes a curved surface.

8. The wearable speaker according to claim 5, wherein

a hole unit is formed on a part of the wall unit.

9. The wearable speaker according to claim 1, wherein

the attached band is a neck hanging unit that is attached on a neck.

10. The wearable speaker according to claim 1, wherein

the wearable speaker is configured to be capable of adjusting a vibration that is produced by operating the passive radiator.

11. A reproduction apparatus, comprising:

a signal processing unit that processes an audio signal; and

a wearable speaker, wherein

the wearable speaker includes

a pair of speaker boxes that are attached on both ends of an attached band, and

a speaker unit and a passive radiator that are attached on each of the speaker boxes.

12. The reproduction apparatus according to claim 11, wherein

the signal processing unit is accommodated in each of the speaker boxes.
