HEADPHONE DEVICE, WEARING STATE DETECTION DEVICE, AND WEARING STATE DETECTION METHOD
First Claim
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.

Abstract
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.

9. A wearing state detection device which detects whether headphones are in a wearing state or a non-wearing state using
a signal comparison result between a sound signal obtained by 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 headphones and a sound signal obtained by 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 headphones, 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.

10. A wearing state detection method of 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, and a driver unit configured to perform an acoustic output, the wearing state detection method comprising:
detecting 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.
