Detailed ways

The current temperature measurement technology mainly includes contact temperature measurement and non-contact infrared temperature measurement. For contact temperature measurement products, the most common is the contact temperature probe, followed by watches and bracelets. The most common infrared temperature measurement products are forehead thermometers and ear thermometers. However, the existing body temperature detection device is usually relatively large, so that the earphone requires a larger internal space to be compatible with the body temperature detection device.

Moreover, the existing earphones with a temperature measurement function will be affected by other signals outside the earphones while acquiring the temperature signal of the human body during the temperature measurement process, so that the temperature detection of the earphones is not accurate enough. Based on this, the present application provides a solution that can realize accurate body temperature detection by the earphone without affecting the structure of the earphone.

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings. The first aspect of the embodiment of the present application provides a body temperature detection device, which is applied to an earphone including an earphone shell 1 and a speaker 2. As shown in FIG. 1, FIG. 1 is a body temperature detection device provided by an embodiment of the application A schematic diagram of the structure of the earphone of the device, the body temperature detection device includes:

A temperature sensor 3, the temperature sensor is at least partially located on the earphone shell 1, and is used for detecting the temperature of the concha or the antitragus at the concha or the antitragus of the ear, and according to the temperature generate electrical signals;

The processing circuit 4 is connected to the temperature sensor, receives the electrical signal, and determines the temperature of the human body according to the electrical signal.

Specifically, the temperature sensor can be fixed on the earphone case through the coupling with the earphone case, and the parts that detect body temperature are partially exposed to the shape of the earphone case, or completely hidden in the inner space of the earphone case, thereby It is not necessary to affect the internal structure and appearance design of the headset.

The temperature sensor is fixed on the earphone shell, and the user can operate the earphone by appropriate rotation, so that the temperature sensor is adjusted to the concha or antitragus of the ear, so that the concha or antitragus can be detected at this position. temperature at the tragus, thereby generating an electrical signal based on said temperature.

Since the temperature of the concha cavity of the ear or the tragus is close to the temperature of the human body, and the temperature measurement at this position is less disturbed by the outside world, the aforementioned solution can be used without affecting the internal structure and appearance design of the earphone. , to achieve accurate measurement of human body temperature.

Optionally, a sensing area may be included in the temperature sensor, so that the temperature of the concha or antitragus of the ear may be detected in a contact or non-contact manner with the human body through the sensing area. The sensing area is the part of the temperature sensor that is used to sense temperature and has a certain boundary. For example, the surface of a specified portion of the sensor is used as the sensing area. In the contact mode, the sensing area may be the upper surface and/or the side surface of the temperature sensor exposed from the earphone shell. In a non-contact manner, the sensing area may be the surface of the temperature sensor that receives the thermal signal of the body temperature.

FIG. 2 is a schematic structural diagram of another earphone with a body temperature detection device provided by an embodiment of the present application. Compared with FIG. 1 , the shape and structure of the temperature sensor are different. In FIG. 1 , it is a contact temperature sensor. In non-contact temperature measurement, that is, the part of the temperature sensor is not in direct contact with the human body, but is measured by the thermal radiation emitted by the human body. As shown in Figure 2, it is an infrared temperature sensor.

The sensing area may be a side surface and/or a surface of a temperature sensor, as shown in FIG. 3 , which is a schematic diagram of a sensing area in a contact temperature sensor provided by an embodiment of the present application, in the schematic diagram The sensing area 51 is the upper surface and the side surface, that is, the contact temperature sensor can make contact with the human body through the upper surface and/or the side surface, so as to obtain the temperature information of the human body. In the infrared temperature sensor, the upper surface can be used as the sensing area.

In the embodiment of the present application, a position corresponding to the sensing area (ie, the concha cavity of the ear or the position opposite the tragus) may be provided on the earphone shell for the temperature sensor to perform temperature detection. The temperature sensor may be fixed on the earphone case by being partially located on the earphone case, so that the sensing area is located on the earphone case at a position corresponding to the concha or antitragus of the ear.

For example, the temperature sensor can be glued on the inner side of the earphone shell through its side or the skirt of the side, or the temperature sensor can be attached to the corresponding fastener on the earphone shell through the provided fasteners (eg, snaps, screws, etc.). It is fitted and fixed on the earphone shell.

Taking the contact sensor as an example, when the temperature sensor is arranged on the earphone shell, the contact sensor can be exposed at a designated position on the earphone (that is, the position of the earphone shell corresponding to the concha cavity of the ear or the position of the antitragus). sensing area. As shown in Figures 4a to 4d, Figures 4a to 4d respectively show schematic diagrams of the positions of the sensing regions under four different viewing angles.

In the case of an infrared sensor, the sensing area can be set at the aforementioned designated position in a semi-exposed form (ie, at the position of the earphone shell corresponding to the concha cavity of the ear or the antitragus). For example, the upper edge of the sensing area is set lower than the upper edge of the earphone shell, so that the sensing area does not need to directly contact the human body.

Further, the sensing area can be set to be located in the earphone shell corresponding to the concha cavity near the ear hole or the earphone shell corresponding to the tragus close to the inter-screen notch, so as to be close to the inner side of the tragus and the inter-screen notch at the same time. The left side is the preferred area, as shown in FIG. 5 , which is a schematic diagram of each position in the human ear.

In this embodiment, since the concha cavity near the ear hole and the antitragus near the inter-screen notch have relatively flat areas, the crowd consistency is better, and it is more ergonomic, and the user can rotate Operation to adjust the earphone can also make the temperature sensor measure these two positions stably and reliably, so that the temperature sensor can obtain stable and reliable temperature data. At the same time, the temperature sensor is closer to the human body and is less disturbed by the outside world, so the temperature measurement is more accurate.

In the aforementioned solution, the temperature information of the human body is obtained through a sensing area in a temperature sensor at least partially located on the earphone shell, the sensing area is used for detecting the temperature in a contact or non-contact manner with the human body, and the sensing area is used to detect the temperature. The measurement area is located at a position of the earphone shell corresponding to the concha cavity of the ear or the tragus, so that the body temperature detection device can collect temperature information in the concha cavity or the tragus of the human body.

Since there is space for the earphones to be used here, the stability is good, and at the same time, it is less affected by the internal temperature of the earphones, and is also less affected by the external temperature. Therefore, it is not necessary to use an additional thermal insulation layer, and since the temperature sensor is partially located on the earphone shell, it can reduce the internal space occupied by the earphone, so that the overall size of the temperature sensor can be accommodated on the earphone, so that the internal structure of the earphone is not affected. Accurate temperature measurement of human body temperature is achieved under the condition of appearance design.

In one embodiment, the temperature sensor is arranged above the speaker of the earphone and is adapted to the shape of the part of the earphone shell located above the speaker.

Because the internal structure of the headset is usually fixed and difficult to change. The speaker is usually located in the middle of the earphone shell. The cavity between the speaker and the earphone shell is the front sound cavity. Therefore, in one embodiment, the temperature sensor can be arranged above the loudspeaker in the inner cavity of the earphone shell (ie, the front sound cavity), which can make use of the existing space (there is no need to separately prepare the earphone in the earphone case). Leave space for the temperature detection device), and it can be far away from other parts in the earphone that may generate heat to reduce the influence of the temperature in the earphone on the detected body temperature.

In general temperature measurement devices, it is necessary to reduce the interference of the environment on temperature measurement based on the thermal insulation layer. Therefore, the thermal insulation layer is usually determined based on the size of the environmental interference. The greater the interference, the thicker the thermal insulation layer, and the interference The smaller it is, the thinner the insulation layer is, and the insulation layer can be eliminated when the environmental disturbance is negligible.

By arranging the temperature sensor above the speaker, on the one hand, the external interference has been basically shielded by the earphone shell, and at the same time, the speaker of the earphone also isolates the interference of other components in the earphone that may generate heat on the temperature measurement. Therefore, here In this embodiment, the thickness of the thermal insulation layer in the body temperature detection device can be reduced or even no thermal insulation layer is required, so as to further reduce the overall thickness of the body temperature detection device.

Further, when the temperature sensor can also be arranged above the speaker in the inner cavity of the earphone shell (ie, the front sound cavity), the temperature sensor can also be arranged as the earphone shell located at the side of the ear and mouth of the earphone. where the temperature sensor is adapted to the shape of the part of the earphone shell located on the side of the ear and above the speaker. As shown in Figure 1 and Figure 2, in the front sound cavity of the earphone, this position has the most abundant space. The speaker is arranged in this position, while avoiding external interference as much as possible, it can also make the size of the temperature sensor suitable. The adjustment space is more convenient for practical industrial design and application.

In one embodiment, the temperature sensor can be attached to the earphone shell, and when the temperature sensor is attached to the earphone shell, the surface shape of the temperature sensor should be consistent with the shape of the earphone shell, so that the temperature sensor can be matched with the earphone shell. The combination is smoother without affecting the shape of the headset.

Specifically, the temperature sensor in the body temperature detection device may be a contact temperature sensor, or the temperature sensor may be an infrared temperature sensor. The contact temperature sensor includes:

The contact piece 301 is used for contacting with the measured object and conducting heat, and the exposed surface of the contact piece forms the sensing area. The contacts can be made of various thermally conductive metals or other thermally conductive materials with good thermal conductivity, and the specific shape can be set according to actual needs. For example, the shape can be cup-shaped to fill the thermally conductive parts;

The temperature measuring element 304 is used for converting the heat transferred by the contact element into an electrical signal, and is electrically connected with the processing circuit; and,

The heat conducting member 303 is at least partially located between the contact member and the temperature measuring member, and the heat conducting member is used for transferring the heat of the contact member to the temperature measuring member. Through the contact temperature sensor of this structure, the human body can be directly contacted through the contact piece, so that the temperature of the human body can be detected more accurately.

In an embodiment, the contact temperature sensor further includes a bracket 302, the bracket is used to support the heat-conducting member, and forms a closed space with the contact member, so that the heat-conducting member and the temperature-measuring member are sealed in the closed space . Therefore, the temperature measuring member only contacts the heat conducting member and is substantially isolated from the outside, thereby avoiding the influence of the external environment.

In an embodiment, the contact-type body temperature detection device further includes a thermally conductive metal glue 305, located at the position where the support and the contact piece are in contact, for sealing the contact position between the support and the contact piece, forming a the confined space. By using the thermal conductive metal glue to seal the bracket and the contact piece, the sealed space can be better sealed, the leakage of the thermal conduction piece can be avoided, and the influence of the environment on the thermal conduction piece can be reduced.

As shown in FIG. 6a, FIG. 6a is a schematic structural diagram of an earphone with a contact temperature sensor provided by an embodiment of the present application. In this embodiment, the contact member may only expose the upper surface to form the sensing area; or may expose part of the side surface while exposing the upper surface, so that part of the side surface and the upper surface together form the sensing area.

In one embodiment, the thickness of the contact temperature sensor (ie H1 shown in Figure 6a) does not exceed 1.65 mm. Therefore, the size of the contact temperature sensor can be made small enough to be suitable for various types of earphones.

Further, since the thickness of the contact temperature sensor is actually the sum of the thickness of the contact piece plus the thickness of the bracket and the height of the enclosed space, specifically, the thickness of the contact piece may not exceed 0.15mm, and the bracket The thickness of the closed space does not exceed 0.3mm, and the height of the closed space does not exceed 1.2mm. Thus, the occupied space is saved, and it can be adapted to more earphone models. In this way, the thickness of the temperature measuring element can be selected to be no more than 1mm thick.

In the contact temperature sensor, the thermally conductive member may be a thermally conductive silica gel layer; the temperature measuring member may be a thermistor; the contact member may be a stainless steel sheet, so as to maintain good performance while maintaining low cost .

Since the contact piece may need to be flush with the outer surface of the earphone shell or even protrude relative to the outer surface of the earphone shell to contact the human body, the contact piece may be in the shape of a racetrack or a circle, which has a more beautiful appearance and can be relatively Stable and reliable contact with human skin.

As shown in Figures 6b and 6c, Figure 6b is an exploded schematic diagram of the components in the contact temperature sensor, and Figure 6c is an assembly schematic diagram of the contact temperature sensor. As shown in the figure, the shape of the contact piece is a racetrack shape, and the contact temperature sensor after assembly is also a racetrack shape.

As mentioned above, the temperature sensor may also be an infrared temperature sensor. As shown in FIG. 7a, FIG. 7a is a schematic structural diagram of an earphone including an infrared temperature sensor provided by an embodiment of the present application. Infrared temperature sensors in this headset include:

The thermal infrared lens 311 is used to transmit thermal infrared rays (usually in the wavelength range of 9000nm-13000nm) generated at the concha cavity of the human body or at the antitragus, the thermal infrared rays represent the temperature information of the human body; and,

a thermal infrared sensor 312 that receives the thermal infrared to generate an electrical signal, the thermal infrared sensor is located under the thermal infrared lens and is connected to the processing circuit;

The sensor carrier board 313 is located under the thermal infrared sensor and is used for supporting the thermal infrared sensor.

Since the infrared temperature sensor is still installed inside the earphone, it will not be disturbed by the external environment. Therefore, the infrared temperature sensor can avoid direct contact with the human body, that is, the user's body temperature information can still be accurately obtained. The user experience is better.

As shown in Figures 7b and 7c, Figure 7b is an exploded schematic diagram of the components of the infrared temperature sensor, and Figure 7c is an assembly schematic diagram of the infrared temperature sensor. In this embodiment, the surface of the thermal infrared lens forms the sensing area.

In an embodiment, the thickness of the infrared temperature sensor does not exceed 1.8mm, specifically, the thickness of the thermal infrared lens (ie, HT in FIG. 7a ) does not exceed 0.5mm. The thickness of the sensor does not exceed 1 mm, and the thickness of the sensor carrier plate does not exceed 0.3 mm. The sum of these three thicknesses is the overall thickness of the infrared body temperature detection device. At this time, the overall thickness of the infrared body temperature detection device (ie, H2 in FIG. 7 a ) does not exceed 1.8 mm. Therefore, the size of the infrared temperature sensor can be made small enough to be suitable for various types of earphones.

In this embodiment, the body temperature detection device can be used for semi-in-ear or in-ear earphones. Since its thickness is ultra-thin, the internal structural features of the earphones combined with the detection position can achieve the effect of saving space. Adapt to various headphone models.

For the infrared temperature sensor, since the upper surface of the thermal infrared lens needs to fit the surface of the earphone, the exposed surface of the thermal infrared lens can be in the shape of a racetrack, which makes it more beautiful when displayed to the user.

In an embodiment, the processing circuit may also be connected to a communication module in the headset, so that the communication module sends the body temperature to the electronic device for communication with the headset, and the electronic device displays the body temperature . The electronic devices may be various user terminals such as smart phones, tablets, personal computers, and the like. The communication module can adopt communication methods such as Bluetooth. Thus, it is convenient for users to know their own temperature situation in real time, and the user experience is improved.

In one embodiment, the processing circuit may be connected to a speaker in the earphone, so that the human body temperature is played through the speaker in the form of a sound signal. The timing of playing can be set according to actual needs, such as playing when the temperature exceeds a certain value, or playing at intervals of a certain period of time, and so on. Thereby, the user's own temperature can be notified in real time, and the user experience can be improved.
