Abstract

A headset includes: a hollow housing to be worn at an ear of a user; a cylindrical ear canal insertion part that is a portion of the housing, and that is provided at a portion of the housing at a side of an ear canal; a thermistor for a headset, provided at the ear canal side inside the housing; a temperature sensor for a headset on a main substrate, provided at an opposite side from the ear canal side inside the housing; and a calculation unit that measures a body temperature of the user based on an output of the thermistor and an output of the temperature sensor.

First claim

1 . A headset, comprising:
a hollow housing to be worn at an ear of a user; a cylindrical ear canal insertion part that is a portion of the housing, and that is provided at a portion of the housing at a side of an ear canal; a first sensor for a headset, provided at the ear canal side inside the housing; a second sensor for a headset, provided at an opposite side from the ear canal side inside the housing; and a calculation unit that measures a body temperature of the user based on an output of the first sensor and an output of the second sensor.

2 . The headset of claim 1 , wherein:
the first sensor includes a proximity sensor for detecting a wearing state or a thermistor for measuring a temperature inside the housing, and the second sensor includes a sensor mounted at a main substrate or a touch pad for detecting an operation by the user.

3 . The headset of claim 1 , wherein the calculation unit:
estimates a room temperature that is a temperature outside the housing, from the output of the first sensor or the second sensor under a predetermined condition, obtains the output of the first sensor and the output of the second sensor, and measures the body temperature of the user from a first temperature difference between the estimated room temperature and a temperature measured from the output of the first sensor, and a second temperature difference between a temperature measured from the output of the second sensor and the temperature measured from the output of the first sensor.

4 . The headset of claim 1 , wherein:
the first sensor comprises a plurality of sensors, the second sensor comprises a plurality of sensors, and the calculation unit:
selects a combination of any one of the plurality of sensors of the first sensor and any one of the plurality of sensors of the second sensor, based on a temperature measured from an output of the plurality of sensors of the first sensor and a temperature measured from an output of the plurality of sensors of the second sensor, and
measures the body temperature of the user based on a temperature measured from an output of a sensor included in the selected combination.

5 . The headset of claim 4 , wherein the calculation unit:
estimates a room temperature that is a temperature outside the housing, from the output of the first sensor or the second sensor under a predetermined condition, obtains the output of the first sensor and the output of the second sensor, selects the combination from a ratio of a first temperature difference between the estimated room temperature calculated for each combination of any one of the plurality of sensors of the first sensor and any one of the plurality of sensors of the second sensor, and a temperature measured from the output of the first sensor, and a second temperature difference between a temperature measured from the output of the second sensor and the temperature measured from the output of the first sensor, and measures the body temperature of the user using the temperature measured from an output of a sensor included in the selected combination and a parameter established in advance for the combination.

6 . The headset of claim 5 , wherein the calculation unit measures the body temperature of the user based on the first temperature difference, the second temperature difference, and the temperature measured from the output of the first sensor, in the selected combination, at a time of measuring the body temperature of the user.
