SOUND PRESENTATION DEVICE |
| 摘要 |
A sound presentation device including: a casing; an electroacoustic transducer that is installed in such a way that a space inside the casing is divided into a first empty chamber and second empty chamber that are acoustically isolated, and that receives an electrical signal and vibrates; and a vibration plate that makes contact with a body surface of a human body when the sound presentation device is mounted on the body surface, and causes vibration of the electroacoustic transducer to be propagated to the human body via the first empty chamber, the second empty chamber suppressing sound waves produced by the vibration of the electroacoustic transducer from being emitted to outside of the sound presentation device via the second empty chamber. |

1. A sound presentation device comprising:
a casing; an electroacoustic transducer that is installed in such a way that a space inside the casing is divided into a first empty chamber and second empty chamber that are acoustically isolated, and that receives an electrical signal and vibrates; and a vibration plate that makes contact with a body surface of a human body when the sound presentation device is mounted on the body surface, and causes vibration of the electroacoustic transducer to be propagated to the human body via the first empty chamber, the second empty chamber suppressing sound waves produced by the vibration of the electroacoustic transducer from being emitted to outside of the sound presentation device via the second empty chamber. |
