When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0023] The present invention provides a wireless headset.
[0024] Combine Figure 1 、 Figure 2 and Figure 4 As shown, in one embodiment of the present invention, the wireless headset includes a charging box 10, an earphone body 20 and a temperature measuring component; the earphone body 20 is movably embedded in the charging box 10, and the earphone body 20 includes a main structure 21, a heating element 22 and a first microprocessor. The heating element 22 and the first microprocessor are both arranged in the main structure 21, and the first microprocessor is communicatively connected to the heating element 22; the temperature measuring component is communicatively connected to the first microprocessor; The first microprocessor controls the heating element 22 to heat the main structure 21 according to the temperature detection result of the temperature measuring component.
[0025] In this embodiment, the charging box 10 is used to place the earphone body 20 and charge the earphone body 20. The main structure 21 includes a housing and necessary components such as a battery and an audio driver unit arranged inside the housing to realize the basic audio functions of the wireless earphone.
[0026] The heating element 22 is made of metal or a metal alloy (such as copper or nickel-chromium alloy) and is positioned within the main structure 21. When current passes through the heating element 22, the heat generated is transferred to the outer shell of the main structure 21, thereby increasing the overall temperature of the earphone body 20. The heating element 22 can be in the form of a mesh, sheet, or block. To further enhance the user's wearing experience, the heating element 22 is positioned on the inner side of the main structure 21 where it contacts the ear.
[0027] The first microprocessor is a low-power, highly integrated microprocessor such as a single-chip microcomputer or an ARM chip, integrated within the main structure 21, and is used to control the operating status of the heating element 22. It will be appreciated that the earphone body 20 also includes a circuit control board for processing and transmitting audio signals, as well as power management, function control, and other functions. The first microprocessor can be integrated into the circuit control board to increase the integration of the earphone body 20.
[0028] The temperature measuring component may include one, two or more temperature measuring elements. For example, a temperature measuring element may be provided on the charging box 10 or the main structure 21 and used to detect the ambient temperature. The temperature measuring element may be a high-precision thermistor or an infrared temperature sensor. When the ambient temperature is lower than the preset temperature, it indicates that the user is currently in a low-temperature environment. At this time, the first microprocessor controls the heating element 22 to be turned on, thereby heating the main structure 21 to improve the wearing comfort of the user. Alternatively, two temperature measuring elements are provided on the main structure 21, wherein one temperature measuring element is used to detect the temperature of the main structure 21, and the other temperature measuring element is used to detect the temperature of the ear surface. When the temperature of the main structure 21 is lower than the temperature of the ear surface, the first microprocessor controls the heating element 22 to be turned on, and heats the main structure 21, thereby reducing the temperature difference between the ear and the earphone body 20, thereby improving the user's wearing experience.
[0029] It can be understood that the present application sets the heating element 22 on the main structure 21, so when the user wears the earphones in a low temperature environment, the heating element 22 can continue to heat the main structure 21 to ensure that the user maintains a good wearing experience during the wearing process.
[0030] The first microprocessor also has a temperature regulation function. When the temperature of the main structure 21 approaches ear temperature, the first microprocessor reduces the power of the heating element 22 to maintain a stable temperature. This dynamic adjustment mechanism not only quickly responds to the user's wearing needs, but also effectively saves power and extends the battery life of the headphones.
[0031] Combine Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the heating element 22 is a mesh structure, and the main structure 21 includes an ear inlet portion 211 and a handle portion 212. The ear inlet portion 211 is arranged on one side of the handle portion 212 and is arranged close to the end of the handle portion 212. The end of the ear inlet portion 211 that is inserted into the ear is the wearing end 211a, and the inner surface of the ear inlet portion 211 and the inner surface of the handle portion 212 close to the wearing end 211a are both provided with a heating element 22.
[0032] In this embodiment, the ear inlet 211 is designed to be oval in shape, fitting the shape of the human ear canal to ensure stability and comfort when worn; the handle 212 is an elongated cylindrical shape, which is convenient for users to operate and wear.
[0033] The mesh structure of the heating element 22 is woven from multiple strands of fine heating wire, distributed along the inner surface of the ear inlet 211 and the inner surface of the handle 212 near the wearing end 211a. This grid-like design not only ensures uniform heating but also effectively reduces the impact of the heating element 22 on the weight and internal volume of the earphone body 20. The heating wire of the mesh heating element 22 is made of nickel-chromium alloy (NiCr), which has high resistivity and excellent high-temperature resistance.
[0034] Furthermore, the heating element 22 with a mesh structure can be an integrally molded structure and distributed on the inner surface of the ear inlet 211 and the inner surface of the handle 212 close to the wearing end 211a; or two heating elements 22 with a mesh structure can be set and respectively arranged on the inner surface of the ear inlet 211 and the inner surface of the handle 212 close to the wearing end 211a.
[0035] In other embodiments, the heater 22 may also be a mesh structure formed by cutting a metal heater sheet, which is attached to the inner walls of the ear inlet 211 and the handle 212. This structural design can improve the convenience of installing the heater 22. Furthermore, when the heater 22 is a metal heater sheet, the metal heater sheet can be made of a highly flexible metal material (such as a nickel-chromium alloy or a titanium alloy) to provide a certain degree of flexibility, further improving the convenience of installing the heater 22.
[0036] Combine Figure 2 As shown, in one embodiment of the present invention, the temperature measuring component includes a first temperature measuring component 23 and a second temperature measuring component 24. The first temperature measuring component 23 is provided on the handle 212 and is used to detect the temperature of the main structure 21. The second temperature measuring component 24 is provided on the ear inlet 211 and is used to detect the temperature of the ear. When the temperature of the main structure 21 is lower than the temperature of the ear, the first microprocessor controls the heating component 22 to be turned on.
[0037] In this embodiment, when the user wears the earphone body 20, the second temperature measuring element 24 is in contact with or close to the ear to improve the accuracy of ear temperature detection. The first temperature measuring element 23 is located on the handle 212, and is located at the end of the handle 212 away from the ear to prevent the first temperature measuring element 23 from mistakenly measuring the temperature of the ear or face. The first temperature measuring element 23 and the second temperature measuring element 24 can both be contact sensors (such as thermocouple sensors) or non-contact sensors (such as thermal infrared sensors). In this embodiment, the first temperature measuring element 23 is a contact sensor, and the temperature measuring end of the sensor is in contact with the surface of the handle 212 to accurately measure the temperature of the handle 212 surface. The second temperature measuring element 24 is a thermal infrared sensor. When the ear inlet 211 is worn in the human ear, the second temperature measuring element 24 can accurately measure the temperature of the ear regardless of whether it is in contact with the human ear.
[0038] It can be understood that in this embodiment, the mechanism for the first microprocessor to trigger the heating element 22 to turn on is set as the temperature T1 of the main structure 21 is lower than the temperature T2 of the ear. In other embodiments, it can also be set to trigger the heating element 22 to turn on when the temperature T1 of the main structure 21 is lower than the temperature T2 of the ear to reach a certain value, that is, T2-T1≥Tx, Tx can be 0, 0.1, 0.2, 0.5 and other values. Since the human body can only clearly perceive the temperature change when the temperature change reaches a certain amount, this setting method can also heat the main structure 21 before the user perceives that the temperature of the earphone body 20 is different from the ear temperature, thereby achieving the effect of improving wearing comfort.
[0039] Furthermore, to improve the accuracy of the first temperature measuring element 23 in measuring the temperature of the earphone body 20, the temperature measuring end of the first temperature measuring element 23 is spaced apart from the heating element 22 to reduce the impact of the high temperature of the heating element 22 on the temperature measurement results of the first temperature measuring element 23. In addition, multiple first temperature measuring elements 23 and second temperature measuring elements 24 can be provided, spaced apart in the handle 212 and the ear inlet 211. The average temperature of the multiple first temperature measuring elements 23 and the multiple second temperature measuring elements 24 can be combined to control the on / off of the heating element 22, thereby improving the accuracy of temperature control of the main structure 21.
[0040] Combine Figure 1 As shown, in one embodiment of the present invention, the temperature measuring assembly further includes a third temperature measuring element 12; the third temperature measuring element 12 is provided on the surface of the charging box 10 or the main structure 21, and is used to detect the ambient temperature; Before the earphone body 20 is worn, when the ambient temperature detected by the third temperature measuring component 12 is lower than a preset low temperature threshold, the first microprocessor controls the heating component 22 to be turned on and preheat the main structure 21 .
[0041] When the ambient temperature is low, when the user picks up the earphone body 20 and wears it on the ear, although the first microprocessor can measure the temperature difference between the main structure 21 and the ear through the first temperature measuring component 23 and the second temperature measuring component 24 to control the start of the heating component 22 to heat the main structure 21, but in the initial stage of wearing, and in the initial stage of heating the main structure 21 by the heating component 22, the temperature of the earphone body 20 is lower than the temperature of the ear, which will cause discomfort to the user for a period of time.
[0042] Therefore, in this embodiment, a third temperature measuring element 12 is provided to detect the ambient temperature and transmit the temperature data to the first microprocessor before the earphone body 20 is worn, thereby preheating the main structure 21. A low temperature threshold value, such as 26°C or 30°C, can be built into the first microprocessor. When the ambient temperature falls below the low temperature threshold value, the first microprocessor controls the activation of the heating element 22 to preheat the main structure 21 before the earphone body 20 is worn.
[0043] In other embodiments, another heating module may be provided in the charging box 10 to preheat the earphone body 20 through the heating module on the charging box 10 to reduce the power loss of the earphone body 20 and extend the wearing time of the earphone body 20.
[0044] Combine Figure 1 As shown, in one embodiment of the present invention, the charging box 10 includes a box body 11 and a second microprocessor, the third temperature measuring component 12 and the second microprocessor are both arranged in the box body 11 and are communicatively connected, and the second microprocessor is communicatively connected to the first microprocessor.
[0045] In this embodiment, the third temperature measuring component 12 is arranged in the box body 11 to reduce the space volume of the main structure 21 occupied by the temperature measuring component. Since the earphone body 20 and the charging box 10 themselves require communication connection to realize functions such as signal transmission and charging, wireless modules are provided in the box body 11 and the main structure 21, and the communication connection between the two is realized through the wireless module. Therefore, even if the third temperature measuring component 12 is arranged in the box body 11 in this embodiment, there is no need to set up an additional communication module. The second microprocessor can realize the communication connection with the first microprocessor through the original wireless module. In addition, the second microprocessor can be a low-power, highly integrated microprocessor such as a single-chip microcomputer or an ARM chip, and is integrated on the circuit control board inside the box body 11.
[0046] Combine Figure 1 As shown, in one embodiment of the present invention, the charging box 10 includes a box body 11, a second microprocessor and a motion detection module 13. The motion detection module 13 is arranged in the box body 11. The motion detection module 13 detects the switch state of the box body 11. The second microprocessor is communicated with the motion detection module 13 and controls the opening of the third temperature measuring component 12 according to the detection result of the motion detection module 13.
[0047] In this embodiment, the motion detection module 13 can be a Hall sensor or a pressure sensor, etc., and can determine whether the user needs to wear headphones by detecting the switch state of the cover of the box body 11. When the second microprocessor detects that the box body 11 is opened through the motion detection module 13, the second microprocessor controls the opening of the third temperature measuring component 12 and detects the current ambient temperature to decide whether to start preheating of the main structure 21. Therefore, through the above technical solution, a mechanism can be implemented to trigger the third temperature measuring component 12 to detect the ambient temperature before the user wears the earphone body 20. Therefore, when the earphone body 20 is charging or idle in the charging box 10, the third temperature measuring component 12 can be kept in a closed state, thereby reducing power consumption and extending the service life of the third temperature measuring component 12.
[0048] In other embodiments, the motion detection module 13 may also be an acceleration sensor, which detects the acceleration change of the box body 11 to determine whether the charging box 10 is picked up, and further determine whether the user wants to wear the earphone body 20. Of course, an acceleration sensor and a Hall sensor can also be provided at the same time to further improve the accuracy of determining whether the user wants to wear the earphone body 20.
[0049] The present invention also provides a temperature control method for a wireless headset as described above. The specific structure of the wireless headset is referred to the above embodiments and will not be described in detail here.
[0050] Among them, combined Figure 5 As shown, in one embodiment of the present invention, the temperature measuring assembly includes a first temperature measuring element 23 and a second temperature measuring element 24, and the temperature control method includes the steps of: S100: Control the first temperature measuring element 23 to collect the current temperature of the main structure 21, and control the second temperature measuring element 24 to collect the thermal temperature of the ear; S200: Compare the current temperature with the thermal temperature; S300 : If the current temperature is lower than the thermal sensing temperature, the heating element 22 is controlled to be turned on and the main structure 21 is heated.
[0051] In this embodiment, both the first temperature measuring element 23 and the second temperature measuring element 24 are connected to the first microprocessor via wires or wireless transmission, transmitting the collected temperature data to the first microprocessor in real time. After receiving the current temperature and the thermal sensor temperature, the first microprocessor processes the two sets of data. The microprocessor includes an internal temperature comparison algorithm that compares the current temperature with the thermal sensor temperature.
[0052] If the current temperature is lower than the thermal sensing temperature, the first microprocessor controls the signal power supply to power the heating element 22. Once current flows through the heating element 22, the heating element 22 can quickly heat up. The first microprocessor also dynamically adjusts the power output of the power supply based on the temperature difference, thereby adjusting the heating power of the heating element 22 to ensure that the temperature of the earphone body 20 is quickly raised to a level close to the ear's temperature.
[0053] Of course, the first microprocessor can also control the temperature measuring component to collect the ambient temperature, and control the heating element 22 to be turned on or off by comparing whether the ambient temperature exceeds a preset low temperature threshold.
[0054] Through the above control method, when the user wears the earphone body 20 in a low temperature environment, the earphone body 20 can heat the main structure 21 through the heating element 22 to make the main structure 21 close to the temperature of the human ear, thereby improving the user's wearing experience.
[0055] Combine Figure 6As shown, in one embodiment of the present invention, the charging box 10 includes a box body 11 and a motion detection module 13, and the temperature measurement component further includes a third temperature measurement component 12; Before the steps of controlling the first temperature measuring element 23 to collect the current temperature of the main structure 21 and controlling the second temperature measuring element 24 to collect the thermal temperature of the ear, the following steps are further included: S101: Control the action detection module 13 to detect whether the box body 11 is in the open state; S102: When the box body 11 is in the open state, controlling the third temperature measuring element 12 to detect the ambient temperature; S103 : If the ambient temperature is lower than a preset low temperature threshold, the heating element 22 is controlled to be turned on and the main structure 21 is preheated.
[0056] In this embodiment, the motion detection module 13 is installed at the junction of the lid and the body 11 of the charging box 10. It uses a Hall effect sensor or a pressure sensor to detect the opening and closing status of the charging box 10. For example, when the user opens the charging box 10, the Hall effect sensor detects the change in the magnetic field and sends a signal to the controller, indicating that the charging box 10 is open. Of course, the motion detection module 13 can also detect the motion state of the body 11 (such as acceleration) to determine whether the user intends to open the body 11.
[0057] When the motion detection module 13 determines that the charging box 10 is in the open state, it sends the detection result to the controller, which immediately activates the third temperature measuring element 12 and controls it to begin detecting the current ambient temperature. The third temperature measuring element 12 transmits the collected ambient temperature data to the controller, which has a built-in low-temperature threshold. The controller determines whether the ambient temperature is below the low-temperature threshold and then controls whether to turn on or off the preheating of the main structure 21.
[0058] By preheating the main structure 21 before the user wears the earphone body 20 , the wearing experience of the user in the early stage of wearing the earphone body 20 is improved.
[0059] The controller in this embodiment may be a first microprocessor or a second microprocessor disposed in the box body 11 .
[0060] When the third temperature-measuring element 12 detects that the ambient temperature is below a preset low-temperature threshold, the first microprocessor controls the activation of the heating element 22, thereby preheating the main structure 21. As can be seen from the above embodiment, the heating element 22 is disposed within the main structure 21 and is used to heat the main structure 21 while the earphone body 20 is being worn. Therefore, in this embodiment, the main structure 21 is preheated by the heating element 22 before wearing. This means that both preheating and heating are achieved through the heating element 22, which can reduce the number of components in the wireless earphones and meet the requirements of miniaturization and lightweight design.
[0061] In other embodiments, a heating module may be provided in the box body 11 of the charging box 10 , and the main structure 21 may be preheated by controlling the heating module when the earphone body 20 is in the charging box 10 .
[0062] Combine Figure 7 As shown, in one embodiment of the present invention, the earphone body further includes a wearing detection module; after the step of controlling the heating element 22 to turn on and preheat the main structure 21, the following steps are further included: S105: Controlling the wearing detection module to detect whether the earphone body 20 is in a wearing state; S106: If the earphone body 20 is in the unworn state and remains in the unworn state for a preset time, the heating element 22 is controlled to turn off the preheating of the main structure 21, and the third temperature measuring element 12 is controlled to turn off.
[0063] In this embodiment, the headset body is further equipped with a wearing detection module for monitoring whether the headset is in a wearing state. The wearing detection module is installed inside the ear inlet 211 or the handle 212 of the headset and uses a high-precision proximity sensor or pressure sensor to realize wearing detection.
[0064] In some usage scenarios, after the user picks up the earphone body 20 from the charging box 10, he does not wear it immediately, or places the earphone body 20 on the desktop. Therefore, in this embodiment, a preset time for not wearing the earphone body 20 is built into the first microprocessor, such as 10 seconds or 20 seconds. When the user opens the box body 11, the first microprocessor starts to control the wearing detection module to detect whether the earphone body 20 is in a wearing state. If the earphone body 20 has not been worn on the human ear after the preset time, the first microprocessor controls the closure of the preheating of the main structure 21 by the heating element 22, and the closure of the collection of the ambient temperature by the third temperature measuring element 12, so as to avoid the heating element 22 preheating the main structure 21 for a long time, and the third temperature measuring element 12 collecting the temperature for a long time, thereby increasing the overall power consumption of the earphone body 20, thereby reducing the power loss of the earphone body 20 and extending the service life of the heating element 22 and the third temperature measuring element 12.
[0065] Combine Figure 8 As shown, in one embodiment of the present invention, if the current temperature is lower than the thermal sensing temperature, the step of controlling the heating element 22 to turn on and heat the main structure 21 further includes: S400: If the current temperature is greater than or equal to the thermal temperature, the heating element 22, the first temperature measuring element 23 and the second temperature measuring element 24 are controlled to be turned off.
[0066] In this embodiment, when the ambient temperature is too high and the headphone power consumption is high, the temperature of the headphone body 20 may exceed the temperature of the ear surface, which may cause discomfort when wearing the headphone. Therefore, when the current temperature measured by the first temperature measuring element 23 is greater than or equal to the thermal temperature measured by the second temperature measuring element 24, the first microprocessor determines that the temperature of the headphone body 20 structure meets or exceeds the wearing requirement. At this time, the power supply is controlled to disconnect the power supply to the heating element 22, and the first and second temperature measuring elements 23, 24 are simultaneously turned off, thereby saving power and extending the battery life of the headphone.
[0067] Furthermore, the first microprocessor is preset with a high temperature threshold. When the current temperature is higher than the heat-sensing temperature, the difference between the current temperature and the heat-sensing temperature is calculated, and a determination is made as to whether the temperature difference is higher than the high temperature threshold. If it is lower than the high temperature threshold, the heating element 22 is controlled to be turned off. If it is higher than the high temperature threshold, the first temperature measuring element 23 and the second temperature measuring element 24 are controlled to be turned off, thereby reducing the power consumption of the earphone body 20. In addition, a cooling module, such as a micro fan or a cooling plate, may also be provided. When the temperature difference is higher than the high temperature threshold, the first microprocessor controls the micro fan to be turned on, thereby improving the heat dissipation efficiency within the earphone body 20 and reducing the temperature of the earphone body 20.
[0068] Combine Figure 9 As shown, in one embodiment of the present invention, the first microprocessor stores a plurality of temperature intervals; if the current temperature is less than the thermal sensing temperature, the step of controlling the heating element 22 to turn on and heat the main structure 21 includes: S310: Calculate the temperature difference between the current temperature and the thermal temperature; S320: Adjust the heating power of the heating element 22 according to the temperature range in which the temperature difference falls.
[0069] In this embodiment, the first microprocessor stores multiple preset temperature intervals, which are used to define the range of the difference between the current temperature and the thermally sensitive temperature. Each temperature interval corresponds to a specific heating power, enabling precise temperature control. By determining the temperature interval in which the temperature difference falls, the heating power can be adjusted according to actual needs.
[0070] For example, the temperature ranges can be set as follows: Range 1: Temperature difference ≤ 5°C; Range 2: 5°C < Temperature difference ≤ 10°C; Range 3: Temperature difference > 10°C. The corresponding heating powers can be set as follows: Range 1: Low power (e.g., 10%); Range 2: Medium power (e.g., 50%); Range 3: High power (e.g., 100%).
[0071] After receiving the current temperature and the heat-sensing temperature, the first microprocessor calculates the difference between the two (ΔT = heat-sensing temperature - current temperature). It then determines whether the temperature difference is less than zero. If ΔT < 0, the current temperature is higher than the heat-sensing temperature, and the process proceeds to the next step. If ΔT ≥ 0, the current temperature has reached or exceeded the heat-sensing temperature, and the heating element 22 and related temperature measuring components are turned off.
[0072] When ΔT < 0, the first microprocessor determines the temperature range to which it belongs based on the calculated temperature difference (ΔT). For example, if ΔT ≤ 5°C, the temperature difference is small and the headphone main structure 21 is close to a comfortable temperature. The first microprocessor controls the heating element 22 to operate at a low power level (e.g., 10%), gradually increasing the temperature of the headphone main structure 21 to avoid overheating.
[0073] If 5°C < ΔT ≤ 10°C, it indicates that the temperature difference is moderate. The first microprocessor controls the heating element 22 to operate at medium power (eg, 50%) to quickly increase the temperature of the earphone main structure 21 to ensure comfort.
[0074] If ΔT>10° C., it means that the temperature difference is large, and the first microprocessor controls the heating element 22 to operate at high power (such as 100%) to quickly heat up to a comfortable temperature range.
[0075] It can be understood that the above-mentioned temperature range and corresponding power output are only one embodiment of the present application. The temperature range can also be set to other ranges, and the corresponding output power can be adjusted according to actual needs.
