Abstract

A mobile telephone has a front wall, a rear wall, a top wall partly continuous with a side face, and a side wall, and includes a vibration-absorbing member between the top wall and each of the rear wall and the side wall, and a cartilage conduction vibration source on the inner side of the top wall. Opposite corner parts of the top wall partly continuous with the side face each serve as a cartilage conduction unit. Or a mobile telephone has a front wall, a rear wall, a top wall, and a side wall, and includes a cartilage conduction vibration source that has a thin shape, that vibrates in a direction perpendicular to the thin shape, and that is affixed to the middle, in the left/right direction, of the inner side of the top wall in a direction parallel to the thin shape.

Claims

1. A mobile telephone having a front wall, a rear wall, a top wall partly continuous with a side face, and a side wall, the mobile telephone comprising:

a vibration-absorbing member between the top wall and each of the rear wall and the side wall; and

a cartilage conduction vibration source on an inner side of the top wall, wherein

opposite corner parts of the top wall partly continuous with the side face each serve as a cartilage conduction unit.

2. The mobile telephone of claim 1, wherein:

the vibration-absorbing member is arranged between the top wall and the front wall.

3. The mobile telephone of claim 1, wherein

the front wall, the rear wall, the top wall, and the side wall are formed of a hard material.

4. The mobile telephone of claim 1, wherein

the cartilage conduction vibration source is a piezoelectric bimorph element.

5. The mobile telephone of claim 1, wherein

the cartilage conduction vibration source is affixed to the inner side of the top wall.

6. The mobile telephone of claim 1, wherein

the cartilage conduction vibration source is supported so as not to make contact with the front wall, and the

the mobile telephone further comprises:

a switching unit for switching whether or not to conduct vibration of the cartilage conduction vibration source to the front wall.

7. The mobile telephone of claim 1, wherein

frequency characteristics of an audio signal that drives the cartilage conduction vibration source are determined based on a language of the audio signal.

8. The mobile telephone of claim 7, further comprising:

a display unit, wherein

the frequency characteristics of the audio signal that drives the cartilage conduction vibration source are changed automatically according to a display language on the display unit.

9. The mobile telephone of claim 1, further comprising:

an adjusting means for adjusting intensity of vibration of the cartilage conduction vibration source at least between a first intensity and a second intensity, wherein

the mobile telephone generates air-conduction sound whose volume changes as the intensity of the vibration changes,

the first intensity is an intensity sufficient to generate air-conduction sound with a volume required in a measurement method conforming to a standard for a common mobile telephone, and

the second intensity is an intensity insufficient to generate air-conduction sound with the volume required in the measurement method conforming to the standard for a common mobile telephone, the second intensity being such that a sound pressure inside an external auditory meatus as measured with the mobile telephone in contact with an ear cartilage with the vibration at the second intensity is higher than a sound pressure inside the external auditory meatus as measured with the mobile telephone out of contact with but close to an entrance of the external auditory meatus with the vibration at the first intensity.

10. The mobile telephone of claim 9, wherein

the air-conduction sound is generated by conducting vibration from the top wall, on which the cartilage conduction vibration source is arranged, to the front wall.

11. The mobile telephone of claim 9, wherein

the cartilage conduction vibration source

has a thin shape,

vibrates in a direction perpendicular to the thin shape, and

is affixed to the inner side of the top wall in a direction parallel to the thin shape.

12. The mobile telephone of claim 1, wherein

the cartilage conduction vibration source is arranged at a middle, in a left/right direction, of the top wall, and

the mobile telephone further comprises:

a front camera at the middle, in the left/right direction, of the top wall, on the inner side thereof.

13. The mobile telephone of claim 1, wherein

the cartilage conduction vibration source is arranged at a middle, in a left/right direction, of the top wall, and

the mobile telephone further comprises:

a proximity sensor unit at a middle, in the left/right direction, of the inner side of the top wall.

14. The mobile telephone of claim 1, wherein

the top wall serves as a cartilage conduction unit when, with a user'"'"'s face pointing ahead, the mobile telephone is held transversely, roughly horizontally, and is put on a front edge part of an entrance of an external auditory meatus.

15. The mobile telephone of claim 14, wherein

the top wall serves as a pressing part for bending a tragus to close the entrance of the external auditory meatus when, with the user'"'"'s face pointing ahead, the mobile telephone is moved rearward.

16. The mobile telephone of claim 14, further comprising:

a explanation unit for explaining a method of use when the top wall serves as the cartilage conduction unit.

17. A mobile telephone having a front wall, a rear wall, a top wall, and a side wall, the mobile telephone comprising:

a cartilage conduction vibration source

that has a thin shape,

that vibrates in a direction perpendicular to the thin shape, and

that is affixed to a middle, in a left/right direction, of an inner side of the top wall in a direction parallel to the thin shape; and

a front camera arranged at the middle, in the left/right direction, of the inner side of the top wall.

18. The mobile telephone of claim 17, wherein

the rear wall, the top wall, and the side wall constitute an integral box-shaped casing, which, when combined with the front wall, permits vibration to conduct from the top wall to the front wall.

19. A mobile telephone having a front wall, a rear wall, a top wall, and a side wall, the mobile telephone comprising:

a cartilage conduction vibration source

that has a thin shape,

that vibrates in a direction perpendicular to the thin shape, and

that is affixed to a middle, in a left/right direction, of an inner side of the top wall in a direction parallel to the thin shape; and

a proximity sensor unit arranged at the middle, in the left/right direction, of the inner side of the top wall.

20. The mobile telephone of claim 19, wherein

the rear wall, the top wall, and the side wall constitute an integral box-shaped casing, which, when combined with the front wall, permits vibration to conduct from the top wall to the front wall.
