Headphone device, wearing state detection device, and wearing state detection method |
摘要 |
Provided is a headphone device including an outside microphone attached to a position at which an extraneous sound is picked up without passing through a shield in a state in which a user is wearing the headphone device, an inside microphone attached to a position at which the extraneous sound is picked up via the shield in the state in which the user is wearing the headphone device, a driver unit which performs an acoustic output, and a wearing state detection unit which detects a wearing or non-wearing state using a signal comparison result between sound signals obtained by the outside and inside microphones, respectively, a pre-stored non-wearing state reference value which is a signal comparison result when the extraneous sound arrives in the non-wearing state, and a pre-stored wearing state reference value which is a signal comparison result when the extraneous sound arrives in the wearing state. |

1. A headphone device comprising:
an outside microphone attached to a position at which an extraneous sound is picked up without passing through a shield in a state in which a user is wearing the headphone device; an inside microphone attached to a position at which the extraneous sound is picked up via the shield in the state in which the user is wearing the headphone device; a driver unit configured to perform an acoustic output; and a wearing state detection unit configured to detect a wearing state or a non-wearing state using a signal comparison result between a sound signal obtained by the outside microphone and a sound signal obtained by the inside microphone, a pre-stored non-wearing state reference value which is a signal comparison result between a sound signal obtained by the outside microphone and a sound signal obtained by the inside microphone when the extraneous sound arrives in the non-wearing state, and a pre-stored wearing state reference value which is a signal comparison result between a sound signal obtained by the outside microphone and a sound signal obtained by the inside microphone when the extraneous sound arrives in the wearing state. |
