It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0026] The temperature determination method, device and electronic device provided in the embodiments of the present application will be described in detail below with reference to the drawings, through specific embodiments and application scenarios.

[0027] Please refer to Figure 1 , which is a structure schematic diagram of the earphone provided in the embodiments of the present application. As Figure 1 shown, the earphone includes:

[0028] The shell 10 is provided with a sound transmission channel in the shell 10;

[0029] A first temperature sensor 20 (each sensor is shown in a dashed box) and a second temperature sensor 30, the first temperature sensor 20 is arranged at a first position in the sound transmission channel, and the second temperature sensor 30 is arranged at a second position in the sound transmission channel, the first position and the second position are spaced apart along the sound transmission direction, the first temperature sensor 20 is used to detect the temperature at the first position in the shell 10, and the second temperature sensor 30 is used to detect the temperature at the second position in the shell 10.

[0030] In the embodiment of the present application, the earphone can be a sound generating device that can be worn at least partially in the user's ear, and the earphone can be a wireless earphone or a wired earphone.

[0031] The shell 10 can also be referred to as the shell of the earphone, which is provided with a sound outlet 100 and a cavity communicating with the sound outlet, and the sound generating assembly 40 of the earphone can be arranged in the cavity, and the sound generating assembly 40 and the sound outlet 100 can form a sound transmission channel. In the case of converting the received electrical signal into sound by the sound generating assembly 40, the sound generated by the sound generating assembly 40 can propagate in the sound transmission channel and be output from the sound outlet 100 to the user's ear.

[0032] In the embodiment of the present application, the earphone further comprises a first temperature sensor 20 and a second temperature sensor 30, which can be any temperature sensor for detecting the temperature in the shell 10.

[0033] The first temperature sensor 20 is arranged at a first position in the sound transmission channel, and the second temperature sensor 30 is arranged at a second position in the sound transmission channel, and the first position and the second position are spaced apart along the sound transmission direction, so that the first temperature sensor 20 and the second temperature sensor 30 can detect the temperature at different positions in the shell 10 along the sound transmission direction, that is, the first temperature sensor 20 detects the first temperature at the first position in the shell 10, and the second temperature sensor 30 detects the second temperature at the second position in the shell 10. Wherein, the sound transmission direction refers to the direction from the sound generating assembly 40 to the sound outlet 100.

[0034] The first position and the second position can be any position in the shell 10. Specifically, the first position and the second position can be arranged close to the sound outlet 100, so that the measured body temperature is more accurate.

[0035] In some embodiments, the earphone can further comprise a third temperature sensor 50, which is arranged on the side of the shell 10 away from the cavity thereof.

[0036] The third temperature sensor 50 can be used to detect the ambient temperature (i.e., the third temperature) of the environment in which the earphone is located when the earphone is worn in the user's ear. Specifically, the third temperature sensor 50 can be arranged away from the sound outlet 100 of the earphone, so that when the earphone is worn in the user's ear, the third temperature sensor 50 can be away from the user's ear, thereby reducing the influence of the target temperature of the user on the accuracy of the third temperature detected by the third temperature sensor 50.

[0037] The third temperature sensor 50 described above can be arranged at any position on the side of the shell 10 away from the cavity thereof. For example, in the case where the shell includes a head portion 11 and a stem portion 12, the head portion 11 is provided with the sound outlet 100 described above, and the stem portion 12 is connected to the head portion 11, and the third temperature sensor 50 described above can be arranged on the head portion 11 or the stem portion 12.

[0038] In some embodiments, the earphone can further be provided with a wearing sensor 60 arranged on the shell 10.

[0039] The wearing sensor 60 can be any sensor that can be used to detect whether the earphone is worn in the user's ear. For example, the wearing sensor 60 described above can include at least one of an infrared sensor and a specific absorption rate (SAR) sensor.

[0040] In the case where the earphone is provided with the wearing sensor 60, the earphone can detect the first temperature and the second temperature, or the first temperature, the second temperature and the third temperature, when it is detected that the earphone is worn in the user's ear.

[0041] It should be noted that the earphone can further be provided with other components. For example, as shown in Figure 2 The earphone can further include a microcontroller unit (MCU) 70, a sensor hub 80 and an antenna 90, and each of the sensors (including the first temperature sensor 20, the second temperature sensor 30, the third temperature sensor 50 and the wearing sensor 60) can be electrically connected to the MCU 70 through the sensor hub 80, and the MCU 70 can be electrically connected to the sound generating assembly 40 and the antenna 90, and the MCU 70 can control the operation of each of the sensors, the sound generating assembly 40 and the antenna 90. In some embodiments, the MCU 70 can determine the target temperature according to the data obtained by each of the sensors.

[0042] Please refer to Figure 3 is a flowchart of a temperature determination method provided by an embodiment of the present application. The temperature determination method is applied to an electronic device, such as Figure 3As shown, the method comprises the following steps:

[0043] Step 301, obtaining a first temperature and a second temperature, the first temperature being detected at a first position in a sound transmission channel of the earphone, the second temperature being detected at a second position in the sound transmission channel, the first position and the second position being spaced apart along a sound transmission direction of the sound transmission channel;

[0044] Step 302, calculating a difference between the first temperature and the second temperature;

[0045] Step 303, in a case where a first duration is less than or equal to a first preset duration, determining a target temperature based on the first temperature and the second temperature, the first duration being a duration during which the difference is less than or equal to a preset temperature threshold.

[0046] In the embodiments of the present application, the first temperature and the second temperature are obtained by detecting the first temperature at the first position in the sound transmission channel of the earphone and the second temperature at the second position in the sound transmission channel, and the difference between the first temperature and the second temperature is calculated. In a case where the first duration during which the difference between the first temperature and the second temperature is less than or equal to the preset temperature threshold is less than or equal to the first preset duration, the target temperature is determined based on the first temperature and the second temperature. In this way, the body temperature of the user can be determined when the user wears the earphone. Since the earphone is an item that can be carried by the user, the application scenario is more flexible and extensive compared to measuring the body temperature by using an ear thermometer, so that the electronic device can obtain the body temperature of the user in time, and the instantaneity of obtaining the body temperature of the user is improved. In addition, since the temperature in the sound transmission channel can reach thermal equilibrium in a case where the difference between the first temperature and the second temperature is less than or equal to the preset temperature threshold, and the first duration under the thermal equilibrium is less than or equal to the first preset duration in a case where the target temperature is determined based on the first temperature and the second temperature, the determined target temperature can be more accurate, and the accuracy of the determined body temperature is improved.

[0047] It should be noted that the above electronic device can be the above earphone, and the earphone can determine the target temperature according to the data detected by the earphone.

[0048] Alternatively, the above electronic device can also be a device other than the above earphone, and the electronic device is connected (which can be wireless or wired connection) with the earphone, so that the earphone can transmit the data obtained by the earphone to the electronic device, and the electronic device can determine the target temperature according to the data transmitted by the earphone. The electronic device can include at least one of a mobile phone, a tablet computer, and a smart wearable device.

[0049] In the above step 301, the above electronic device can obtain the above first temperature and second temperature.

[0050] Specifically, in the case that the electronic device is the earphone, the earphone can detect the first temperature at the first position by the first temperature sensor, and detect the second temperature at the second position by the second temperature sensor.

[0051] Alternatively, in the case that the electronic device is connected with the earphone, and the earphone detects the first temperature and the second temperature by the first temperature sensor and the second temperature sensor respectively, the earphone can transmit the first temperature and the second temperature to the electronic device.

[0052] The first temperature and the second temperature can be obtained by the electronic device according to a preset period. For example, the electronic device can obtain the first temperature and the second temperature every 1 minute (i.e. the preset period), and the like.

[0053] In the step 302, after the electronic device obtains the first temperature and the second temperature, the electronic device can calculate the difference between the first temperature and the second temperature.

[0054] For example, the MCU of the earphone can obtain the first temperature and the second temperature, and calculate the difference between the first temperature and the second temperature; alternatively, the electronic device can receive the first temperature and the second temperature, and calculate the difference between the first temperature and the second temperature.

[0055] It should be noted that the difference between the first temperature and the second temperature can be the value obtained by subtracting the second temperature from the first temperature, or the value obtained by subtracting the first temperature from the second temperature. Specifically, the difference between the first temperature and the second temperature can also be the absolute value obtained by subtracting the second temperature from the first temperature.

[0056] In the step 303, after the electronic device calculates the difference between the first temperature and the second temperature, the electronic device can compare the difference between the first temperature and the second temperature with a preset temperature threshold, and determine the target temperature based on the first temperature and the second temperature in the case that the first duration in which the difference is less than or equal to the preset temperature threshold is less than or equal to a first preset duration.

[0057] Since the first position and the second position are distributed along the sound transmission direction in the sound transmission channel, there is a temperature difference between the first temperature and the second temperature.

[0058] The preset temperature threshold can be a preset temperature threshold in the electronic device, and the preset temperature threshold can be used to indicate whether the temperature in the earphone is in thermal equilibrium. In other words, when the difference between the first temperature and the second temperature is less than or equal to the preset temperature threshold, it is determined that the temperature in the earphone is in thermal equilibrium; and when the difference between the first temperature and the second temperature is greater than the preset temperature threshold, it is determined that the temperature in the earphone is not in thermal equilibrium.

[0059] When the electronic device determines that the temperature in the earphone is in thermal equilibrium, the electronic device can obtain a first duration in which the temperature in the earphone is in thermal equilibrium. When the first duration is less than or equal to a first preset duration, the electronic device can determine that the heat generated by the internal device of the earphone has little effect on the temperature detected by the first temperature sensor and the second temperature sensor. In this case, the electronic device can determine a target temperature based on the first temperature and the second temperature. The target temperature can be the body temperature of the user.

[0060] The preset temperature threshold and the first preset duration can be values preset in the electronic device, and both of them can be obtained through historical experimental data.

[0061] The determination of the target temperature based on the first temperature and the second temperature can be that the first temperature and the second temperature are input into a preset temperature calculation formula, and the target temperature is output. For example, the average of the first temperature and the second temperature can be used as the target temperature, and so on.

[0062] In the embodiments of the present application, after the electronic device determines the target temperature, the electronic device can output the target temperature to enable the user to know the target temperature in time.

[0063] For example, when the electronic device is an earphone, the earphone can output the target temperature through voice broadcasting, and so on. When the electronic device is connected with the earphone, the electronic device can display the target temperature, and so on.

[0064] In some embodiments, before the target temperature is determined based on the first temperature and the second temperature, the method further includes:

[0065] obtaining a third temperature, the third temperature being an ambient temperature detected outside the sound transmission channel.

[0066] After the difference between the first temperature and the second temperature is calculated, the method can further include:

[0067] When the first duration is greater than the first preset duration, the target temperature is determined based on the first temperature, the second temperature, and the third temperature.

[0068] In the embodiment, when the first duration is greater than the first preset duration, the heat generated by the internal device of the earphone is continuously increased, so that the heat generated by the internal device of the earphone has an impact on the temperature detected by the first temperature sensor and the second temperature sensor. The target temperature is determined based on the ambient temperature and the first temperature and the second temperature, so that the accuracy of the determined body temperature can be improved.

[0069] The target temperature determined based on the first temperature, the second temperature and the third temperature can be that the electronic device is preconfigured with weights corresponding to the first temperature, the second temperature and the third temperature, and the target temperature is calculated based on the first temperature, the second temperature, the third temperature and the weights corresponding to the temperatures.

[0070] In some embodiments, the second target temperature is generated based on the first temperature, the second temperature and the third temperature, comprising:

[0071] The compensation temperature is determined based on the third temperature and the first duration.

[0072] The target temperature is determined based on the first temperature, the second temperature and the compensation temperature.

[0073] In the embodiment, because the duration (i.e. the first duration) of the heat generated by the internal device of the earphone is different during the determination of the target temperature, the influence on the first temperature and the second temperature is different, so the compensation temperature is determined based on the third temperature and the first duration, and the target temperature is determined based on the first temperature, the second temperature and the compensation temperature, so that the accuracy of the determined body temperature can be further improved.

[0074] The compensation temperature determined based on the third temperature and the first duration can be that a temperature proportion coefficient corresponding to the first duration is determined according to a preset mapping relationship between duration and temperature proportion, and a product of the third temperature and the determined temperature proportion coefficient is determined as the compensation temperature. The mapping relationship between duration and temperature proportion can be constructed by a large amount of historical experimental data.

[0075] The target temperature determined based on the first temperature, the second temperature and the compensation temperature can be that an average value of the first temperature and the second temperature is obtained, and a sum of the obtained average value and the compensation temperature is determined as the target temperature. It should be noted that the compensation temperature can be positive or negative.

[0076] In some embodiments, before the target temperature is determined based on the first temperature and the second temperature, the method further comprises:

[0077] Obtain a plurality of sets of historical body temperature data, each set of historical data including a first historical temperature, a second historical temperature, and a historical body temperature, the first historical temperature being detected at a first position, and the second historical temperature being detected at a second position;

[0078] Based on the plurality of sets of historical body temperature data, generate a temperature mapping relationship table, the mapping relationship table including a plurality of mapping relationships, each mapping relationship indicating a relationship between the first historical temperature, the second historical temperature, and the historical body temperature.

[0079] The above determination of the target temperature based on the first temperature and the second temperature can include:

[0080] In the mapping relationship table, the historical body temperature having a mapping relationship with the first temperature and the second temperature is determined as the target temperature.

[0081] In the present embodiment, through the plurality of sets of historical body temperature data, a temperature mapping relationship table can be generated, and in the process of determining the target temperature, the actual historical body temperature having a mapping relationship with the first temperature and the second temperature is found in the temperature mapping relationship table as the target temperature, which not only improves the efficiency of determining the body temperature, but also improves the accuracy of the determined body temperature.

[0082] The first historical temperature and the second historical temperature can be measured by the above earphone or other earphones having the same structure as the above earphone; and the historical body temperature can be an actual body temperature measured by other body temperature measuring devices (such as an ear thermometer) having a measurement accuracy higher than a preset accuracy when the first historical temperature and the second historical temperature are measured.

[0083] Of course, the electronic device can also be pre-set with a mapping relationship table corresponding to the first temperature, the second temperature, and the third temperature, and through the mapping relationship table, the historical body temperature having a mapping relationship with the first temperature, the second temperature, and the third temperature can be determined as the target temperature; or, a mapping relationship table corresponding to the third temperature, the duration, and the compensation coefficient can also be pre-set, each mapping relationship in the mapping relationship table being a corresponding relationship between the third historical temperature, the historical duration, and the historical compensation temperature, the third historical temperature being a historical environmental temperature, and the historical compensation temperature being determined by the historical body temperature and the first historical temperature and the second historical temperature, so that the compensation temperature having a mapping relationship with the third temperature and the first duration can be determined, and the target temperature can be determined by the first temperature, the second temperature, and the compensation temperature.

[0084] In the embodiment of the present application, when the difference between the first temperature and the second temperature is greater than the preset temperature threshold, i.e., when the earphone is not in thermal equilibrium, the electronic device can continuously acquire the first temperature and the second temperature until the difference between the first temperature and the second temperature is less than or equal to the preset temperature threshold, and determine the target temperature.

[0085] In some embodiments, after the difference between the first temperature and the second temperature is calculated, the method further includes:

[0086] When the second duration is greater than or equal to the second preset duration, the target temperature is determined based on the first temperature, the second temperature, and the third temperature, and the second duration is the duration during which the difference is greater than the preset temperature threshold.

[0087] In the embodiment, when the duration during which the earphone is not in thermal equilibrium reaches the second preset duration, the electronic device can determine the target temperature based on the first temperature, the second temperature, and the third temperature, thereby improving the immediacy of determining the body temperature.

[0088] The process of determining the target temperature based on the first temperature, the second temperature, and the third temperature when the second duration is greater than or equal to the second preset duration can be the same as the process of determining the target temperature based on the first temperature, the second temperature, and the third temperature when the first duration is greater than the first preset duration, and thus will not be described here.

[0089] In some embodiments, the method of acquiring the first temperature and the second temperature includes:

[0090] When the earphone is worn in the user's ear, the first temperature and the second temperature are acquired.

[0091] Therefore, the first temperature and the second temperature are acquired only when it is determined that the earphone is worn in the user's ear, so as to determine the target temperature, thereby reducing the misoperation of the electronic device and saving the power consumption of the electronic device.

[0092] To facilitate the understanding of the method of determining the temperature provided by the embodiments of the present application, the actual application process of the method will be described here. Figure 4 The method includes the following steps 401 to 407.

[0093] Step 401: detecting the wearing state of the earphone by a wearing sensor.

[0094] Step 402: determining whether the earphone is worn in the ear according to the wearing state, i.e., the wearing sensor transmits sensing data to the MCU, and the MCU determines whether the earphone is worn in the ear.

[0095] Step 403, when it is determined that the earphone is worn on the ear, the temperature sensors are controlled to start temperature detection, and timing is started.

[0096] Step 404, the first temperature TEMP1 collected by the first temperature sensor, the second temperature TEMP2 collected by the second temperature sensor, and the third temperature TEMP3 collected by the third temperature sensor are acquired.

[0097] Step 405, it is determined whether the difference between the first temperature and the second temperature in the earphone is less than or equal to a preset temperature threshold ΔTthr, that is, whether Δ|TEMP1-TEMP2|≤ΔTthr is satisfied.

[0098] Step 406, if Δ|TEMP1-TEMP2|≤ΔT thr , it is determined that the earphone reaches thermal equilibrium, and it is determined whether the timing duration t (i.e., the first duration) is less than or equal to t s1 .

[0099] If t≤t s1 , it indicates that the time for the earphone to reach thermal equilibrium is short enough, and the temperature rise effect in the earphone is not enough to affect the sensing of the temperature sensor 1 and the temperature sensor 2. It is determined that the target temperature is only related to the sensing value TEMP1 of the temperature sensor 1 and the sensing value TEMP2 of the temperature sensor 2, and the target temperature TEMP=f(TEMP2,TEMP1) (i.e., the target temperature is determined based on the first temperature and the second temperature) can be determined. Wherein, f(TEMP2,TEMP1) is a TEMP, TEMP1, TEMP2 relationship table (i.e., a mapping relationship table) that can be established according to historical measurements of different ear temperature groups in different environmental temperatures.

[0100] If t>t s1 , it indicates that the time for the earphone to reach thermal equilibrium is not short enough, and the temperature rise effect in the earphone can affect the sensing of the temperature sensor 1 and the temperature sensor 2. At this time, it is considered that the target temperature is not only related to TEMP1 and TEMP2, but also related to TEMP3 collected by the temperature sensor 3, and the target temperature TEMP=f(TEMP2,TEMP1)+f(TEMP3,t) (i.e., the target temperature is determined based on the first temperature, the second temperature, and the third temperature) can be determined. f(TEMP3,t) is a relationship between the temperature value TEMP3 of the temperature sensor 3, the time t, and the measured compensation value.

[0101] Step 407, if Δ|TEMP1-TEMP2|>ΔT thr , it is determined that the earphone does not reach thermal equilibrium, and timing is continued, and it is determined whether the timing duration t (at this time, t=t+1, i.e., the second duration) reaches the second preset duration t s, if t s , re-control the first temperature sensor, the second temperature sensor and the third temperature sensor to collect temperature; if t s , forcedly output value, determine target temperature TEMP = f'(TEMP2, TEMP1) + f'(TEMP3, t) (i.e. determine target temperature based on first temperature, second temperature and third temperature). f'(TEMP2, TEMP1) is a table of TEMP, TEMP1, TEMP2 relationship established according to historical measurement of different ear temperature population at different ambient temperature; f'(TEMP3, t) is a relationship established according to historical measurement of temperature sensor 3 temperature value TEMP3, time t and measured compensation value.
