As shown in fig. 1 and 2, the earphone of the embodiment of the present invention includes an earphone housing 1 and a heat sensing means 2. When wearing the headset of the embodiment of the present invention, the headset housing 1 has a contact area 11 contacting with a human body, and the contact area 11 is shown by a hatched portion in fig. 1. The contact area 11 is provided with an opening, and the thermal sensing device 2 is fixedly arranged in the opening to measure the temperature of the human body. When the earphone is used, the heat sensing device 2 is contacted with a human body, heat emitted by the human body is collected in a contact heat transfer mode and converted into a temperature value, and therefore the temperature of the human body is obtained. The thermal induction device 2 is in contact with a human body to measure the temperature, so that the loss of heat emitted by the human body can be reduced, and the accuracy of temperature measurement can be improved.

According to an embodiment of the present invention, the earphone housing 1 includes a contact region 11 in contact with a human body and an outer region not in contact with the human body. In some embodiments, the contact area 11 of the earphone housing 1 is the area that contacts the human ear when the earphone is worn, and the outer area is the area that does not contact the human ear when the earphone is worn. The shape of the earphone housing 1 may be the same as that of the housing of the earphone in the art, and is not limited herein.

According to an embodiment of the utility model, an opening is provided in the contact area 11 of the earphone housing 1, and the heat sensing means 2 is provided in the opening and is in contact with the human body. The cross-section of the opening may be circular and the cross-section of heat sensing device 2 may also be circular, and the size of the cross-section of heat sensing device 2 is matched to the size of the cross-section of the opening to enable heat sensing device 2 to be placed within the opening. The cross section of the opening may also be square, rectangular parallelepiped or trapezoidal, and accordingly, the shape of the cross section of the heat sensing device 2 may also be square, rectangular parallelepiped or trapezoidal.

In some embodiments, an aperture extends through the earphone housing 1, and the thermal sensing device 2 is disposed within the aperture. In some embodiments, the opening may be a blind hole, and the opening of the opening penetrates through the side of the earphone housing 1 facing the skin of the human body. The heat sensing device 2 is arranged in the opening, one side of the heat sensing device is in contact with a human body, and the other side of the heat sensing device is in contact with the bottom of the opening. The bottom of the opening may be provided with a slit or a hole for electrical connection of the thermal sensing device 2 to other components. In some embodiments, heat sensing device 2 may be secured within the aperture by gluing.

In some embodiments, an opening is formed through the earphone housing 1, the height of the heat sensing device 2 is the same as the thickness of the earphone housing 1, and both sides of the heat sensing device 2 are flush with both ends of the opening, so that the heat sensing device 2 is located in the opening and can be in contact with a human body. In some embodiments, the height of thermal sensing device 2 may also be greater than the thickness of earphone housing 1. The side of the thermal sensing device 2 facing the human body is flush with the end of the opening in contact with the human body, so that the thermal sensing device can be more smoothly placed in the ear of the human body when the earphone is used, and the comfort level of a user can be improved. In some embodiments, the height of the thermal sensing device 2 may also be smaller than the thickness of the earphone housing 1, and the side of the conductive sensing device 2 facing the human body is flush with the end of the opening contacting the human body, so that the conductive sensing device 2 can contact the human body, thereby improving the detection accuracy.

According to an embodiment of the present invention, the contact area 11 includes an ear-entering portion 111 contacting with the external auditory canal, and the contact area 11 may further include an external auditory canal portion 112 contacting with other portions of the human body except the external auditory canal, as shown in fig. 2, wherein two shades in fig. 2 are respectively shown as the ear-entering portion 111 and the ear-entering portion 112. The opening can be arranged in the ear-entering part 111 or in the outer ear part 112 to realize the temperature measurement of different positions of the human ear.

For the human body, the temperature at the hypothalamus can relatively accurately reflect the temperature of the human body. And within the ear canal, the blood temperature in blood vessels distributed at the eardrum is similar to that in blood vessels of the inferior colliculus. Therefore, the closer to the eardrum, the human ear is, the more the temperature reflects the actual temperature of the human body. Therefore, for temperature measurement, the location of the thermometry needs to be as close to the eardrum as possible. Furthermore, the closer the blood vessel the more accurate the measured temperature.

The concha is closer to the eardrum than other parts such as the auricle, and the earphone housing 1 is more contacted by the earphone than the inner part of the external auditory canal, so the opening can be arranged in the area where the ear-entering part 111 can contact with the concha to improve the accuracy of temperature measurement.

As shown in fig. 8, fig. 8 is a schematic view of a human ear in which the ear artery is close to the external auditory meatus, and the ear artery is one of important blood vessels in the ear. The flow of blood in the auricular artery is larger than that of blood in other small blood vessels, so that the temperature of the human body can be reflected more accurately. Further, as shown in fig. 8, the upper part 12 and the lower part 13 of the external auditory meatus are closer to the auricular artery than the two sides of the external auditory meatus, and the temperature at the upper part 12 and the lower part 13 of the external auditory meatus can reflect the temperature of the human body more accurately. Therefore, in some embodiments, an opening is provided at the top of the ear-entering portion 111 so that the heat sensing device 2 can measure the temperature of the upper part 12 of the outer ear door, thereby improving the accuracy of the measurement result. In some embodiments, an opening is provided in the bottom of the ear-entering portion 111 so that the heat sensing device 2 can measure the temperature of the lower portion 13 of the outer ear door.

With the embodiment of the present invention, the opening is provided in the region that can contact with the external auditory meatus of the human body, so that the heat sensing device 2 located in the opening can detect above or below the external auditory meatus. Meanwhile, the external auditory meatus is closer to the eardrum relative to the auricle and is easier to touch relative to the external auditory meatus earphone, so that the temperature at the external auditory meatus is measured, the accuracy of temperature measurement can be guaranteed, and the measurement is easy to realize.

According to an embodiment of the utility model, the headset of an embodiment of the utility model further comprises a thermally insulating layer 3. Thermal-sensitive device 2 sets up in the trompil, and one side is towards the earphone shell 1 outside, and the inner chamber that the opposite side formed towards earphone shell 1 sets up insulating layer 3 including the intracavity, and parcel thermal-sensitive device 2 separates thermal-sensitive device 2 and the component that is located the inner chamber towards the one side of inner chamber. When the earphone provided by the embodiment of the utility model is used, the element positioned in the inner cavity generates heat when working, and the heat generated by the element is blocked in the inner cavity by utilizing the heat-insulating layer 3, so that the influence of the heat generated by the element on the heat induction device 2 is avoided, and the accuracy of measurement can be ensured.

According to the embodiment of the utility model, part of the heat insulation layer 3 is connected with the earphone housing 1 to form a containing cavity with an opening as an opening, and the heat sensing device 2 is arranged in the containing cavity to thermally isolate the heat sensing device 2 from the inner cavity.

As shown in fig. 3, the earphone is split along the dotted line on fig. a in fig. 3, and the earphone is projected from the direction indicated by the arrow on the dotted line, so as to obtain a diagram b in fig. 3. In fig. b, the thermal sensing means 2 is located in the opening, and the height of the thermal sensing means 2 is the same as the thickness of the opening of the earphone housing 1. The heat insulation layer 3 is arranged in the inner cavity and connected with the earphone shell 1 to form an accommodating cavity with the opening as an opening. The thermal sensing device 2 is positioned in the accommodating cavity so as to realize that the thermal sensing device 2 is separated from the inner cavity by the heat insulation layer 3.

Fig. 4 schematically illustrates the position relationship of the heat insulating layer 3 and the earphone housing 1, and as shown in fig. 4, in some embodiments, the periphery of the heat insulating layer 3 is connected with the periphery of the opening of the earphone housing 1 to seal the opening and prevent the heat in the inner cavity from affecting the heat sensing device 2.

The temperature sensing member 21 is in contact with a human body, and heat emitted from the human body is transferred to the temperature sensing member 21. A difference in heat is formed in the temperature sensing part 21, and the difference in heat can indicate a change in heat information before and after the temperature sensing part 21 is in contact with the human body.

In addition, other technologies with short-distance wireless communication and control functions can also be applied to the headset of the embodiment of the utility model to realize the communication between the headset of the embodiment of the utility model and other communication devices. The connection board 4 serves to electrically connect the heat sensing device 2 and the bluetooth chip 5 between the heat sensing device 2 and the bluetooth chip 5. In some embodiments, the connection board 4 is a flexible circuit board. The connection board 4 may also be other devices that can electrically connect the thermal sensing device 2 and the bluetooth chip 5, and is not limited herein.

The value range of the normal temperature of the human body can be set by a person skilled in the art according to the actual situation, and the normal temperature of the human body is not limited herein. For example, according to the measurement results, the normal temperature of a certain user is set to be 35.5 ℃ to 37.1 ℃. When the temperature measured by the user is 27 ℃, the bluetooth chip 5 may send a second signal to the mobile phone application program according to the measurement result, so as to prompt the user to check whether the wearing is correct.

In addition, the bluetooth chip 5 may also transmit the first signal or the second signal to the user terminal 6 according to the detected temperature value.

For example, when the user terminal 6 sends a request for obtaining a temperature value, and when the temperature value detected this time belongs to the normal temperature of the human body, the bluetooth chip 5 sends the temperature value detected this time to the user terminal 6. Or, under the condition that the temperature value detected at this time is higher than the normal temperature of the human body, the bluetooth chip 5 sends the temperature value detected at this time and the first signal to the user terminal 6 so as to inform the user of the temperature measurement result at this time and remind the user of the abnormality of the temperature measurement at this time.
