Abstract
Disclosed is a device and method for monitoring an earphone wearing state. A device and method for monitoring an earphone wearing state according to the present invention comprises: an internal microphone for receiving an internal voice generated inside an ear and generating an internal voice signal; an external microphone for receiving an external sound selectively including external noise and an external voice transferred from a vocal cords to the outside of an oral cavity and generating an external sound signal; a control unit for determining the volume of external noise though a comparison between an internal voice signal and an external sound signal and determining whether to generate an alarm signal; and an alarm unit for performing alarming in response to an alarm signal.
Claims6
A device for monitoring an earphone wearing state, the device comprising:
- an internal microphone for receiving an internal voice that is generated by a wearer of the device and transferred through an ear of the wearer and for generating an internal voice signal using the received internal voice;
- an external microphone for receiving an external sound including at least one of an external voice that is generated by the wearer and transferred from vocal cords to the outside of an oral cavity of the wearer and an external noise, and for generating an external sound signal using the received external sound;
- a control unit for determining, based on the internal voice signal and the external sound signal, whether or not to generate an alarm signal that indicates an improper earphone wearing state;
- and
- an alarm unit for generating an alarm in response to the alarm signal,
- wherein, responsive to the internal voice generated by the wearer and responsive to a high frequency signal that exceeds a frequency band of the internal voice and is included in the internal voice signal, the control unit considers the high frequency signal as a noise and generates the alarm signal.
A method of monitoring an earphone wearing state, the method comprising the steps of:
- receiving, from an internal microphone, an internal voice signal generated using an internal voice, the internal voice being generated by a wearer of the earphone and transferred through an ear of the wearer;
- receiving, from an external microphone, an external sound signal generated using an external sound, the external sound including at least one of an external voice that is generated by the wearer and transferred from vocal cords to the outside of an oral cavity of the wearer and an external noise;
- and
- determining, based on the internal voice signal and the external sound signal, whether or not to generate an alarm signal that indicates an improper earphone wearing state;
- and
- responsive to the internal voice generated by the wearer and responsive to a high frequency signal that exceeds a frequency band of the internal voice and is included in the internal voice signal, considering the high frequency signal as a noise and generating the alarm signal.
