[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] The Bluetooth connection method provided in this application can be applied to, for example... Figure 1 In the application environment shown, Bluetooth device 102 communicates with Bluetooth device 104 via Bluetooth. For example, Bluetooth device 102 is a first Bluetooth headset, and Bluetooth device 104 is a second headset or mobile phone. The first and second Bluetooth headsets can be the left and right earpieces of a TWS (True Wireless Stereo) Bluetooth headset. Both Bluetooth device 102 and Bluetooth device 104 can include an antenna, speaker, microphone, Bluetooth main control circuit, and battery. When Bluetooth device 102 and Bluetooth device 104 pair or reconnect, they connect via Bluetooth signals. The Bluetooth signal can be any signal sent by the Bluetooth transceiver during the Bluetooth connection process in the Bluetooth standard, or it can be a signal transmitted in certain states, such as Bluetooth signals transmitted in Bluetooth paging, Bluetooth inquiry, or Bluetooth response states, such as the ID packet transmitted in Bluetooth paging state. The inventors discovered through analysis that during Bluetooth connection, especially in paging or querying states, the transmission of ID packets and other information packets across various frequency bands based on frequency hopping protocols can cause significant current fluctuations. This can easily lead to electromagnetic radiation from Bluetooth devices interfering with sensitive components such as speakers and microphones. This interference is particularly pronounced in compact devices like Bluetooth headsets, where the close proximity of components makes the interference even more noticeable, thus affecting the user experience.

[0029] Therefore, in order to solve the above problems, in one embodiment, such as Figure 2 As shown, a Bluetooth connection method is provided, which is applied to... Figure 1 Taking a Bluetooth device as an example, the explanation includes the following steps:

[0030] S201, During part or all of the process of establishing a Bluetooth connection, the Bluetooth device transmits a Bluetooth signal according to a preset transmission power, such that the radiated noise generated by transmitting the Bluetooth signal satisfies the first condition.

[0031] Understandably, the process of establishing a Bluetooth connection includes different stages (such as query, query scan, paging, paging scan, etc.). The steps involved in a Bluetooth connection may differ in scenarios such as initial Bluetooth connection, Bluetooth pairing, and Bluetooth reconnection. This embodiment can be applied to part or all of the process of establishing a Bluetooth connection. For example, the Bluetooth connection method can be applied to the Bluetooth paging page process; and / or the Bluetooth inquiry process. Furthermore, it can be applied to part or all of the process of re-establishing a Bluetooth connection after an abnormal Bluetooth connection interruption. In this case, Bluetooth may be interfered with (e.g., by body obstruction), or it may be interfered with by distance (e.g., by being far from the audio source device), or it may be caused by other abnormal reasons that cause the Bluetooth connection to be interrupted during use. At this time, the Bluetooth device will re-establish the Bluetooth connection, for example, by entering the paging state and transmitting ID packets based on the frequency hopping protocol (i.e., in the Bluetooth paging page process of re-establishing the Bluetooth connection after an abnormal Bluetooth connection interruption). Since the Bluetooth signal will be transmitted for a certain period of time in certain frequency bands and the frequency band will be switched rapidly, it will cause current fluctuations and other problems, thereby generating background noise (radiated noise). At this time, the Bluetooth device transmits Bluetooth signals according to a preset transmission power, thereby controlling the radiated noise generated by transmitting Bluetooth signals by controlling the Bluetooth transmission power, so as to meet the first condition, and thus control the impact of background noise on the user. Of course, in some cases, Bluetooth devices need to be in polling mode during the connection process. In polling mode, Bluetooth signals need to be transmitted across various frequency bands, which may generate radiated noise. To reduce noise, the Bluetooth signal can be transmitted at a preset transmission power. For ease of control, the preset transmission power can also be used to transmit Bluetooth signals throughout the entire Bluetooth connection establishment process.

[0032] Understandably, the preset transmission power differs from the Bluetooth transmission power of the Bluetooth device after establishing a Bluetooth connection. That is, during part or all of the Bluetooth connection establishment process, the Bluetooth transmission power can be adjusted to the preset transmission power. This preset transmission power may differ from the transmission power used when sending Bluetooth data during the Bluetooth connection state, thereby enabling control of Bluetooth radiated noise in specific scenarios. Generally, the preset transmission power can be lower than the Bluetooth transmission power of the Bluetooth device after establishing a Bluetooth connection, thereby reducing Bluetooth radiated noise generated during the connection process (especially during Bluetooth paging or querying). In this embodiment, during part or all of the Bluetooth connection establishment process, the Bluetooth device transmits a Bluetooth signal according to the preset transmission power, such that the radiated noise generated by transmitting this Bluetooth signal satisfies a first condition. The first condition characterizes the degree to which the radiated noise is perceived by the user. Understandably, due to differences in human hearing perception, the degree of perception of radiated noise also varies from person to person. To control the impact of radiated noise generated by Bluetooth devices during connection, the first condition could be that the user cannot perceive the radiated noise at all. In this case, there might be no radiated noise, or the generated radiated noise is so weak that the user cannot perceive it. Alternatively, the radiated noise that the user can perceive could be less than a predetermined value, making the radiated noise less impactful on the user, thus balancing connection efficiency and the impact of radiated noise on the user. Specifically, the first condition can be characterized by low power consumption and low current fluctuation when the Bluetooth device transmits Bluetooth signals, resulting in weak radiated noise. Taking Bluetooth headsets as an example, during the process of establishing a connection between Bluetooth headsets and other Bluetooth devices, the first condition could be that the radiated noise generated by the Bluetooth headset when transmitting Bluetooth signals is very weak, and the human ear can barely perceive it. Or, the first condition could be that the radiated noise generated by the Bluetooth headset when transmitting Bluetooth signals can be perceived by the user, but to a very weak degree. Due to differences in individual user perception capabilities, under the same circumstances, some users may be able to perceive the noise while others may not. Therefore, the first condition may include some radiated noise parameters to measure the generated radiated noise. For example, the parameter may include a threshold for the intensity (in decibels) of the radiated noise. If the intensity of the radiated noise generated when transmitting Bluetooth signals is controlled to be less than the threshold during part or all of the Bluetooth connection establishment process, the radiated noise generated when transmitting Bluetooth signals may not be perceived by the user, or the radiated noise generated when transmitting Bluetooth signals may be perceived by the user, but the perceived radiated noise is very weak and will not affect the performance of the Bluetooth device.

[0033] It should be noted that the aforementioned first condition may differ depending on the usage scenario of the Bluetooth device. Taking Bluetooth headsets as an example, when using Bluetooth headsets in a noisy environment, the first condition regarding the control of radiated noise can be relatively low. That is, the preset transmission power can be controlled relatively high. Although the generated radiated noise will be greater, it will be difficult for the user to perceive due to the noisy environment. When using Bluetooth headsets in a quiet environment, the first condition regarding the control of radiated noise can be relatively high. That is, in a quiet environment, the preset transmission power needs to be controlled relatively low to avoid generating radiated noise or to ensure that the generated radiated noise is not perceived by the user. For example, when elderly people use Bluetooth headsets, the first condition regarding the control of radiated noise can be relatively low. Elderly people have weaker sound perception, so it is permissible to increase the transmission power, and even if the generated radiated noise is slightly greater, it will not affect the use. However, when young people or adults use Bluetooth headsets, the first condition regarding the control of radiated noise can be relatively high to avoid excessive noise affecting the user experience. This application does not impose any limitations.

[0034] In the scenario described above where the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device satisfies the first condition, the first condition may be that the intensity of the radiated noise is less than the intensity of the reference radiated noise, which is the intensity of the radiated noise generated by transmitting the Bluetooth signal according to the Bluetooth transmission power in the Bluetooth connection state during part or all of the process of establishing a Bluetooth connection.

[0035] Understandably, in this embodiment, taking a Bluetooth headset as an example, if a Bluetooth connection is established using the Bluetooth transmission power in a Bluetooth connection state or a Bluetooth signal is transmitted in a paging state, the user wearing the Bluetooth headset can perceive radiated noise (i.e., reference radiated noise). However, if the Bluetooth transmission power is adjusted to a preset transmission power under the same conditions, the user will not perceive radiated noise (floor noise) or the perceived radiated noise intensity will be less than the intensity of the reference radiated noise (because there may be other reasons for the floor noise or the floor noise generated by Bluetooth transmission has not been completely eliminated, only the radiated noise has been reduced). In one embodiment, the first condition characterizes the degree to which radiated noise is perceived by the user. In this embodiment, the first condition characterizes the degree to which the radiated noise generated by the Bluetooth device transmitting Bluetooth signals is perceived by the user. Optionally, the first condition may characterize the degree to which the intensity of the radiated noise generated by the Bluetooth device transmitting Bluetooth signals is perceived by the user. The degree to which noise is perceived by the user can include being insufficient to be perceived by the user or being very weak (weaker than a specific threshold, which can be set as needed and may also be affected by individual differences in perception). For example, 1 decibel is generally the sound that the human ear can just barely hear, and sounds below 20 decibels are generally considered quiet. Therefore, radiated noise below 1 decibel is insufficient to be perceived by the user, and sounds between 1 and 20 decibels can be considered to be very weakly perceived by the user. This embodiment of the application is not limited to this. It is understood that due to individual differences, the degree to which radiated noise is perceived by the user will also vary. For example, users of different age groups can be pre-selected in different environments to test the degree to which users of each age group perceive radiated noise in various environments. Alternatively, a device simulating the human ear can be used to measure the degree to which these simulated human ears perceive radiated noise in different environments, thereby determining the degree to which the radiated noise generated when the Bluetooth device transmits Bluetooth signals is perceived by the user in various scenarios. Understandably, since each user's perception level may be different, the first condition of user perception level can also be expressed as controlling the radiated noise to a level that most users cannot perceive. For example, out of 100 random users, more than 50 should not perceive it. The specific percentage can be adjusted according to the product's performance requirements.

[0036] In this embodiment, since the first condition characterizes the degree to which the radiated noise generated by the Bluetooth device transmitting Bluetooth signals is perceived by the user, and the radiated noise generated by the Bluetooth device transmitting Bluetooth signals satisfies the first condition, that is, the radiated noise generated by the Bluetooth device when transmitting Bluetooth signals is within the acceptable range perceived by the user. In this case, the power consumed by the Bluetooth device when transmitting Bluetooth signals is small, thereby reducing the current fluctuation generated by the Bluetooth device, and thus reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones, that is, reducing the interference of the Bluetooth device on sensitive devices such as speakers and microphones when sending Bluetooth connection request signals.

[0037] In another embodiment of the scenario described above where the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device satisfies the first condition, the above-described method of ensuring that the radiated noise generated by the transmitted Bluetooth signal satisfies the first condition includes: making the intensity of the radiated noise generated by the transmitted Bluetooth signal less than or equal to a reference value of the minimum radiated noise perceptible to the human ear.

[0038] In this embodiment, the Bluetooth signal transmitted by the Bluetooth device according to the preset transmission power is such that the intensity of the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device is less than or equal to the reference value of the minimum radiated noise perceptible to the human ear. The sound frequencies perceptible to the human ear are generally between 20 Hz and 20,000 Hz, but there are individual differences, and these differences also exist at different ages. For example, some adults can perceive sound frequencies generally between 30-16,000 Hz, while older adults can generally perceive sound frequencies between 50-10,000 Hz. Therefore, a perceptible reference value can be selected, such as 20 Hz, or 30 Hz. For example, at 30 Hz, some users may be able to perceive it, but some users may not perceive it very clearly, or some users may not perceive it at all. For example, taking the reference value of the minimum radiated noise perceptible to the human ear as 20 Hz, the intensity of the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device according to the preset transmission power must be less than or equal to 20 Hz. It should be noted that the reference value for the minimum radiated noise that the human ear can perceive can vary depending on the group of people or the environment. For example, the reference value for the minimum radiated noise that adults can perceive is 20 Hz, while the reference value for the minimum radiated noise that the elderly can perceive is 25 Hz or 30 Hz. The selection of the minimum radiated noise reference value can be based on the performance requirements of the product. For example, choosing a minimum radiated noise reference value can ensure that most users cannot perceive the radiated noise or perceive it as very weak, thus improving the applicability of Bluetooth devices to most users.

[0039] In this embodiment, since the intensity of the radiated noise generated by the Bluetooth device transmitting Bluetooth signals according to the preset transmission power is less than or equal to the reference value of the minimum radiated noise that can be perceived by the human ear, the power consumed by the Bluetooth device when transmitting Bluetooth signals is small, thereby making the current fluctuation generated by the Bluetooth device weaker, thus reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones, that is, reducing the interference of the Bluetooth device on sensitive devices such as speakers and microphones when sending Bluetooth connection request signals.

[0040] In another embodiment of the scenario described above where the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device satisfies the first condition, the above-described method of ensuring that the radiated noise generated by the transmitted Bluetooth signal satisfies the first condition includes: making the radiated noise generated by the transmitted Bluetooth signal less than or equal to a reference value of the absolute threshold of human hearing.

[0041] In this embodiment, the Bluetooth signal transmitted by the Bluetooth device according to the preset transmission power is such that the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device is less than or equal to the reference value of the absolute threshold of human hearing. The absolute threshold of human hearing refers to the weakest sound perceived by the human auditory system. In this embodiment, the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device is less than or equal to the reference value of the absolute threshold of human hearing, meaning that the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device is less than or equal to the weakest sound perceived by the human auditory system. For example, taking the reference value of the absolute threshold of human hearing as 19 Hz, the intensity of the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device according to the preset transmission power must be less than or equal to 19 Hz. It should be noted that the reference value of the absolute threshold of human hearing can be different for different groups of people or in different environments. For example, the reference value of the minimum radiated noise perceptible to adults is 19 Hz, while the reference value of the minimum radiated noise perceptible to the elderly is 23 Hz or 28 Hz.

[0042] In this embodiment, since the radiated noise generated by the Bluetooth device transmitting Bluetooth signals according to the preset transmission power is less than or equal to the reference value of the absolute threshold of human hearing, the power consumed by the Bluetooth device when transmitting Bluetooth signals is small, thereby making the current fluctuation generated by the Bluetooth device weaker, thus reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones, that is, reducing the interference of the Bluetooth device on sensitive devices such as speakers and microphones when sending Bluetooth connection request signals.

[0043] In one embodiment of the scenario where the radiated noise generated by the Bluetooth signal transmitted by the Bluetooth device satisfies the first condition, the above-mentioned method of making the radiated noise generated by the Bluetooth signal satisfy the first condition includes: making the intensity of the radiated noise generated by the Bluetooth signal satisfy a second condition, wherein the second condition characterizes the degree to which the intensity of the radiated noise is perceived by the user.

[0044] In this embodiment, the intensity of the radiated noise generated by the Bluetooth device transmitting Bluetooth signals satisfies a second condition. This second condition characterizes the degree to which the intensity of the radiated noise is perceived by the user, that is, the intensity of the radiated noise generated by the Bluetooth device transmitting Bluetooth signals satisfies the degree to which it is perceived by the user. The degree to which it is perceived by the user can include being insufficient to be perceived by the user or being very weak. For example, typically, 1 decibel is the sound that the human ear can just barely hear, and sounds below 20 decibels are generally considered quiet. Therefore, radiated noise below 1 decibel is insufficient to be perceived by the user, and sounds between 1 decibel and 20 decibels can be considered to be very weakly perceived by the user. This embodiment is not limited to these possibilities. It is understood that due to individual differences, the degree to which radiated noise is perceived by the user will also vary. For example, users of different age groups can be pre-selected in different environments to test the degree to which users of each age group perceive radiated noise in various environments. Alternatively, a device simulating the human ear can be used to measure the degree to which these simulated human ears perceive radiated noise in different environments, thereby determining the degree to which the radiated noise generated by the Bluetooth device transmitting Bluetooth signals is perceived by the user in various scenarios.

[0045] In this embodiment, since the second condition characterizes the degree to which the intensity of the radiated noise generated by the Bluetooth device transmitting Bluetooth signals is perceived by the user, and the intensity of the radiated noise generated by the Bluetooth device transmitting Bluetooth signals satisfies the second condition, that is, the intensity of the radiated noise generated by the Bluetooth device when transmitting Bluetooth signals is not perceived by the user, or is within the acceptable range perceived by the user. In this case, the power consumed by the Bluetooth device when transmitting Bluetooth signals is small, thereby making the current fluctuation generated by the Bluetooth device weaker, thereby reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones, that is, reducing the interference of the Bluetooth device on sensitive devices such as speakers and microphones when sending Bluetooth connection request signals.

[0046] In the scenario described above where the Bluetooth device transmits Bluetooth signals according to a preset transmission power, the focus is on how to ensure that the radiated noise generated by transmitting the Bluetooth signal meets the first condition. The following section details the process of determining this transmission power. It should be noted that the preset transmission power can be determined by the Bluetooth device itself or by a designated Bluetooth device. This designated Bluetooth device can be the aforementioned Bluetooth device or a Bluetooth device with the same performance characteristics, such as an engineering prototype or a pilot production prototype. After determining the preset transmission power through testing, it is set in the aforementioned Bluetooth device during mass production. Alternatively, the power can be determined according to user needs after the Bluetooth device leaves the factory; the principle remains the same, and this application does not impose any restrictions on this.

[0047] In this embodiment, before transmitting a Bluetooth signal according to the preset transmission power, the preset transmission power needs to be determined first, so that the radiated noise generated by transmitting the Bluetooth signal satisfies the first condition mentioned above. Optionally, the preset transmission power can be obtained through testing before the Bluetooth device leaves the factory, and can be determined manually or by machine testing. For example, by adjusting the current Bluetooth transmission power of a specified Bluetooth device, when the radiated noise generated by transmitting a Bluetooth signal at the current Bluetooth transmission power during part or all of the Bluetooth connection establishment process satisfies the first condition mentioned above, the current Bluetooth transmission power is determined as the preset transmission power. Typically, the Bluetooth transmission power of a Bluetooth device is 0 dBm to 10 dBm. The Bluetooth device can adjust its Bluetooth transmission power starting from 0 dBm through preset frequency adjustment intervals. When the radiated noise generated by the Bluetooth device transmitting a Bluetooth signal satisfies the first condition mentioned above, the current Bluetooth transmission power is determined as the preset transmission power. For example, taking a preset frequency adjustment interval of 2dBm as an example, the Bluetooth device starts from 10dBm and adjusts the Bluetooth transmission power of the Bluetooth device at a frequency adjustment interval of 2dBm. When the Bluetooth transmission power of the Bluetooth device is adjusted to 4dBm, the radiated noise generated by transmitting the Bluetooth signal meets the above-mentioned first condition. Then the Bluetooth device determines the current transmission power of 4dBm as the above-mentioned preset transmission power. The embodiments of this application are not limited thereto.

[0048] In other words, the preset transmission power can be determined by a designated Bluetooth device, which includes the aforementioned Bluetooth device or other Bluetooth devices with the same performance as the aforementioned Bluetooth device. Furthermore, determining the preset transmission power by a designated Bluetooth device includes: determining the transmission power corresponding to the designated Bluetooth device based on the radiated noise generated by the Bluetooth signal transmitted by the designated Bluetooth device during part or all of the Bluetooth connection establishment process, when the radiated noise satisfies any of the aforementioned first conditions.

[0049] To improve the versatility of the preset transmission power, for example, using a Bluetooth headset as the Bluetooth device, 100 users can be randomly selected, and the transmission power of the specified Bluetooth headset can be adjusted. When the adjusted transmission power makes the radiated noise generated by transmitting the Bluetooth signal imperceptible to more than 60 of the 100 users, this transmission power is determined as the preset transmission power. Optionally, the specific percentage of users who cannot perceive the radiated noise generated by transmitting the Bluetooth signal can be adjusted according to the product's performance requirements. Of course, it can also be determined based on the perception level of a specific person (e.g., a person with high hearing sensitivity).

[0050] In some embodiments, since there may be multiple preset transmission powers that enable the radiated noise to meet the first condition, for example, within a certain range, but some transmission powers may be too low and detrimental to Bluetooth connectivity, it is also necessary to consider the performance of the Bluetooth connection. Bluetooth connection performance can be measured by methods such as Bluetooth connection speed at a specific distance. For example, Bluetooth connection performance can include meeting connection requirements within a specific distance, such as meeting Bluetooth connection speed requirements or Bluetooth connection duration requirements. Therefore, the Bluetooth device can determine the preset transmission power based on the radiated noise generated by its transmitted Bluetooth connection signal and the preset Bluetooth connection performance. The preset Bluetooth connection performance can be determined based on product requirements, user experience, etc. For example, determining the preset transmission power includes: adjusting the current Bluetooth transmission power of a specified Bluetooth device, wherein when transmitting the Bluetooth signal (the Bluetooth signal during part or all of the process of establishing a Bluetooth connection) at the current Bluetooth transmission power meets the preset Bluetooth connection performance and the generated radiated noise meets a first condition, the current Bluetooth transmission power is used as the preset transmission power. For example, the preset transmission power is determined such that, during part or all of the process of establishing a Bluetooth connection, the radiated noise generated at the preset transmission power is not perceived by the user, or is perceived by the user to a very weak degree, and the preset transmission power is conducive to establishing a Bluetooth connection.

[0051] In other words, the preset transmission power can be determined based on the radiated noise generated by the specified Bluetooth device during part or all of the Bluetooth connection establishment process and the preset Bluetooth connection performance. Furthermore, the preset transmission power is determined based on the transmission power of the specified Bluetooth device when the Bluetooth signal transmitted by the specified Bluetooth device during part or all of the Bluetooth connection establishment process meets the preset Bluetooth connection performance and the radiated noise generated meets any of the aforementioned first conditions. In the above Bluetooth connection method, during part or all of the Bluetooth connection establishment process, since the Bluetooth device transmits the Bluetooth signal according to the preset transmission power, the radiated noise generated by the transmitted Bluetooth signal can meet the first condition. Since the preset transmission power can ensure that the radiated noise generated by the transmitted Bluetooth signal meets the first condition, that is, the radiated noise generated by the transmitted Bluetooth signal is not perceived by the user or is perceived by the user to a very weak degree (weaker than a specific threshold, which can be set as needed and may also be affected by individual perception differences), the preset transmission power needs to ensure that the power consumed by the Bluetooth device when transmitting the Bluetooth signal is small, thereby reducing the current fluctuation generated by the Bluetooth device and reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones.

[0052] In this embodiment, the Bluetooth device determines the preset transmission power before transmitting the Bluetooth signal according to the preset transmission power. This ensures that the Bluetooth device transmits the Bluetooth signal at the preset transmission power, so that the radiated noise generated by transmitting the Bluetooth signal meets the first condition. This ensures that the Bluetooth device consumes less power when transmitting the Bluetooth signal, thereby reducing the current fluctuation generated by the Bluetooth device and reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones.

[0053] In the scenario described above where a Bluetooth device generates radiated noise by transmitting a Bluetooth signal at a preset transmission power, in one embodiment, the intensity of the radiated noise generated by the Bluetooth device transmitting the Bluetooth signal is related to the transmission power of the Bluetooth device and the device parameters of the Bluetooth device.

[0054] In this embodiment, the intensity of radiated noise generated by the Bluetooth device transmitting Bluetooth signals is correlated with the Bluetooth device's transmission power and device parameters. Optionally, the Bluetooth device parameters include at least one of the following: speaker sensitivity, distance between the speaker and battery, and antenna efficiency. Optionally, the correlation between the intensity of radiated noise generated by the Bluetooth device transmitting Bluetooth signals and the Bluetooth device's transmission power and device parameters includes at least one of the following: speaker sensitivity is positively correlated with radiated noise intensity; distance between the speaker and battery is negatively correlated with radiated noise intensity; antenna efficiency is positively correlated with radiated noise intensity; and transmission power is positively correlated with radiated noise intensity. Understandably, the speaker sensitivity of a Bluetooth device is positively correlated with the intensity of radiated noise; that is, the higher the speaker sensitivity, the greater the radiated noise, and vice versa. The distance between the speaker and battery is negatively correlated with the intensity of radiated noise; the greater the distance, the weaker the radiated noise, and vice versa. The antenna efficiency is positively correlated with the intensity of radiated noise; the higher the antenna efficiency, the stronger the radiated noise, and vice versa. Finally, the transmission power of a Bluetooth device is positively correlated with the intensity of radiated noise; the higher the transmission power, the greater the radiated noise, and vice versa.

[0055] In this embodiment, the intensity of the radiated noise generated by the Bluetooth device transmitting Bluetooth signals is related to the transmission power and device parameters of the Bluetooth device. Therefore, Bluetooth headsets with different device parameters may generate different radiated noises during the Bluetooth connection process. Due to the influence of device structure design, these device parameters are often difficult to adjust, especially for small devices such as Bluetooth headsets, where the space for adjusting device parameters is limited. Therefore, adjusting the Bluetooth transmission power is used to control the noise radiation in part or all of the Bluetooth connection establishment process, solving the background noise problem from other angles and improving the product performance of the Bluetooth device.

[0056] In the scenario described above where the Bluetooth device transmits a Bluetooth signal according to a preset transmission power, the Bluetooth device is a Bluetooth headset. In one embodiment, the Bluetooth device transmitting a Bluetooth signal according to a preset transmission power includes: when it is determined that the Bluetooth headset is being worn by a user, transmitting a Bluetooth signal according to the preset transmission power.

[0057] In this embodiment, the Bluetooth headset transmits a Bluetooth signal according to the preset transmission power when it is determined that the user is wearing the headset. Since headsets typically have small speakers, the sound is easily heard when the headset is worn. If not worn, noise will not affect the user's experience, allowing for greater focus on connection performance, such as reconnection speed. Optionally, the Bluetooth headset can determine whether the user is wearing the headset by its distance from the user, by using its infrared detection device to check if the device detects the user's skin, or by using its temperature detection device to check the ambient temperature. It is understood that by only transmitting a Bluetooth signal at the preset transmission power when the user is confirmed to be wearing the headset, a balance can be struck between noise and connection performance, improving the user experience.

[0058] In this embodiment, when it is determined that the user is wearing the Bluetooth headset, transmitting Bluetooth signals according to a preset transmission power can reduce the power consumption of the Bluetooth headset and reduce the fluctuation of the Bluetooth headset current. This reduces the interference of electromagnetic radiation on sensitive components such as the speaker and microphone of the Bluetooth headset, reduces the user's perception of radiated noise, and improves the user experience.

[0059] In the scenario where the Bluetooth device transmits a Bluetooth signal according to a preset transmission power, the Bluetooth signal is a Bluetooth broadcast signal (e.g., a Bluetooth signal transmitted in query or paging state). In one embodiment, such as... Figure 3 As shown, the above method also includes:

[0060] S301, obtain the signal strength of the Bluetooth connection request signal fed back by other Bluetooth devices based on the Bluetooth broadcast signal.

[0061] In this embodiment, the Bluetooth device transmits a Bluetooth broadcast signal according to the aforementioned transmission power, and obtains the signal strength of the Bluetooth connection request signal fed back by other Bluetooth devices based on the Bluetooth broadcast signal. Optionally, the Bluetooth device can be a Bluetooth headset, and correspondingly, other Bluetooth devices can be headphones, televisions, mobile phones, etc. For example, taking a Bluetooth headset as the Bluetooth device and a mobile phone as another Bluetooth device, the Bluetooth headset transmits a Bluetooth broadcast signal at the aforementioned preset transmission power, the mobile phone receives the Bluetooth broadcast signal, and feeds back a Bluetooth connection request signal to the Bluetooth headset based on the Bluetooth broadcast signal, and the Bluetooth headset obtains the signal strength of the fed-back Bluetooth connection request signal.

[0062] S302, adjust the preset transmission power within the preset transmission power range according to the signal strength to obtain the target transmission power.

[0063] Within the preset transmission power range, the radiated noise generated when the Bluetooth device transmits Bluetooth signals satisfies the first condition. That is, the radiated noise generated when the Bluetooth device transmits Bluetooth signals using the transmission power within the preset transmission power range satisfies the first condition.

[0064] In this embodiment, the Bluetooth device adjusts the preset transmission power within a preset transmission power range based on the signal strength of the Bluetooth signals received from other Bluetooth devices to obtain the target transmission power. Optionally, if the signal strength of the Bluetooth signals received from other Bluetooth devices is weak, the Bluetooth device can increase the preset transmission power within the preset transmission power range to obtain the target transmission power; conversely, if the signal strength of the Bluetooth signals received from other Bluetooth devices is strong, the Bluetooth device can decrease the preset transmission power within the preset transmission power range to obtain the target transmission power. This embodiment does not impose any limitations. In this embodiment, since the transmission power of the Bluetooth device is adjusted within the preset transmission power range, the radiated noise generated when the Bluetooth device transmits the Bluetooth signal at this power satisfies the first condition. Adjusting the transmission power at this time can meet the requirements of reducing power consumption or improving Bluetooth connection performance.

[0065] S303 uses the target transmit power to send a Bluetooth connection response signal, so that the radiated noise generated by transmitting the Bluetooth connection response signal satisfies the first condition.

[0066] In this embodiment, the Bluetooth device transmits a Bluetooth connection response signal using the target transmission power obtained above, such that the radiated noise generated by transmitting the Bluetooth connection response signal satisfies the first condition mentioned above. The first condition can be that the Bluetooth device consumes less power, experiences less current fluctuation, and generates weaker radiated noise when transmitting the Bluetooth connection response signal; that is, the Bluetooth device consumes less power, experiences less current fluctuation, and generates weaker radiated noise when transmitting the Bluetooth connection response signal to other Bluetooth devices using the determined target transmission power.

[0067] In this embodiment, the Bluetooth device obtains the signal strength of the Bluetooth connection request signal fed back by other Bluetooth devices based on the Bluetooth broadcast signal it transmits. It can then adjust its preset transmission power within a preset transmission power range based on the signal strength to obtain the target transmission power. Since the Bluetooth device can dynamically adjust its transmission power according to the signal strength of other Bluetooth devices, it can meet the requirements for Bluetooth connection quality during the Bluetooth connection process. Furthermore, by using the target transmission power to send a Bluetooth connection response signal to other Bluetooth devices, the radiated noise generated by transmitting the Bluetooth connection response signal satisfies the first condition. This allows the Bluetooth device to consume less power when transmitting the Bluetooth connection response signal, thereby reducing the current fluctuations generated by the Bluetooth device and reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones.

[0068] In the scenario where the Bluetooth device adjusts its preset transmission power within a preset transmission power range based on the signal strength of the Bluetooth connection request signal fed back by other Bluetooth devices to obtain a target transmission power, in one embodiment, the above S202 includes: if the signal strength is less than a preset signal strength threshold, then within the preset transmission power range, gradually increase the transmission power of the Bluetooth device according to a preset first adjustment amount until a preset first adjustment end condition is met to obtain the target transmission power;

[0069] The first adjustment termination condition includes a signal strength not less than a signal strength threshold, or a Bluetooth device’s transmit power not less than the maximum power within the transmit power range.

[0070] In this embodiment, if the signal strength of the Bluetooth connection request signal from other Bluetooth devices is less than a preset signal strength threshold, the Bluetooth device gradually increases its transmission power within the preset transmission power range according to a preset first adjustment amount until a preset first adjustment termination condition is met, thereby obtaining the target transmission power. The first adjustment termination condition includes either the signal strength of the Bluetooth connection request signal from other Bluetooth devices being no less than the preset signal strength threshold, or the transmission power of the Bluetooth device being no less than the maximum power within the preset transmission power range. For example, taking a Bluetooth connection request signal strength of 3dBm from another Bluetooth device, a preset signal strength threshold of 8dBm, a preset transmission power range of 2dBm to 10dBm, and a first adjustment amount of 2dBm as an example, if the signal strength of the Bluetooth connection request signal from another Bluetooth device is 5dBm, which is less than the preset signal strength threshold of 8dBm, then the Bluetooth device can gradually increase its transmission power within the 2dBm to 10dBm range by adjusting the amount by 2dBm until the signal strength of the Bluetooth connection request signal from another Bluetooth device is not less than 8dBm, or the transmission power of the Bluetooth device is not less than the maximum power within the aforementioned transmission power range, i.e., not less than 10dBm. It should be noted that if the Bluetooth device gradually increases its transmission power by adjusting the amount by 2dBm, resulting in a transmission power of 11dBm, then the Bluetooth device will use the maximum power within the transmission power range, 10dBm, as the target transmission power and discard the obtained 11dBm.

[0071] In this embodiment, if the signal strength of the Bluetooth connection request signal from another Bluetooth device is less than a preset signal strength threshold, the Bluetooth device gradually increases its transmission power within a preset transmission power range according to a preset first adjustment amount until a preset first adjustment termination condition is met, thus obtaining the target transmission power. Since increasing the transmission power of the Bluetooth device when the received Bluetooth connection request signal is weak allows for rapid establishment of a Bluetooth connection, avoiding poor connection quality due to low transmission power. Furthermore, the Bluetooth device uses the target transmission power to send the Bluetooth connection response signal, ensuring that the radiated noise generated during transmission satisfies the first condition. This reduces the power consumed by the Bluetooth device when transmitting the Bluetooth connection response signal, resulting in weaker current fluctuations and reduced interference from electromagnetic radiation to sensitive devices such as speakers and microphones.

[0072] In the scenario described above, where the Bluetooth device adjusts its preset transmission power within a preset transmission power range based on the signal strength of the Bluetooth connection request signal fed back by other Bluetooth devices to obtain a target transmission power, in another embodiment, the above S302 includes: if the signal strength is greater than or equal to a preset signal strength threshold, then within the preset transmission power range, the transmission power of the Bluetooth device is gradually reduced according to a preset second adjustment amount until a preset second adjustment end condition is met to obtain the target transmission power;

[0073] The second adjustment termination condition includes the signal strength being less than the signal strength threshold, or the Bluetooth device's transmit power being less than the minimum power within the transmit power range.

[0074] In this embodiment, if the signal strength of the Bluetooth connection request signal from another Bluetooth device is greater than or equal to a preset signal strength threshold, the Bluetooth device gradually reduces its transmission power within the preset transmission power range according to a preset second adjustment amount until a preset second adjustment termination condition is met, thereby obtaining the target transmission power. The second adjustment termination condition includes either the signal strength of the Bluetooth connection request signal from another Bluetooth device being less than the preset signal strength threshold, or the Bluetooth device's transmission power being less than the minimum power within the preset transmission power range. For example, taking a Bluetooth connection request signal strength of 9dBm from other Bluetooth devices, a preset signal strength threshold of 5dBm, a preset transmission power range of 2dBm to 10dBm, and a first adjustment amount of 2dBm as an example, if the signal strength of the Bluetooth connection request signal from other Bluetooth devices is 9dBm, which is greater than the preset signal strength threshold of 8dBm, then the Bluetooth device can gradually reduce its transmission power within the transmission power range of 2dBm to 10dBm by adjusting the amount by 2dBm until the signal strength of the Bluetooth connection request signal from other Bluetooth devices is less than 5dBm, or the transmission power of the Bluetooth device is less than the minimum power within the aforementioned transmission power range, i.e., less than 2dBm.

[0075] In this embodiment, if the signal strength of the Bluetooth connection request signal received from other Bluetooth devices is greater than or equal to a preset signal strength threshold, the Bluetooth device gradually reduces its transmission power within a preset transmission power range according to a preset second adjustment amount until a preset second adjustment termination condition is met, thus obtaining the target transmission power. When the received Bluetooth connection request signal has a strong signal strength, the Bluetooth device's transmission power can be appropriately reduced to decrease power consumption. Furthermore, the Bluetooth device uses the target transmission power to send the Bluetooth connection response signal, ensuring that the radiated noise generated by transmitting the Bluetooth connection response signal meets the first condition. This reduces the power consumed by the Bluetooth device when transmitting the Bluetooth connection response signal, resulting in weaker current fluctuations and thus reducing interference from electromagnetic radiation to sensitive devices such as speakers and microphones.

[0076] In one embodiment, such as Figure 4 As shown, an earphone is provided, including: a processor, a transceiver connected to the processor, a speaker, and a battery;

[0077] The processor is used to control the transceiver to transmit Bluetooth signals according to a preset transmit power during part or all of the Bluetooth connection establishment process, so that the radiated noise generated by the transceiver transmitting Bluetooth signals satisfies a first condition.

[0078] In this embodiment, the earphone's processor controls the transceiver to transmit Bluetooth signals according to a preset transmission power during part or all of the Bluetooth connection establishment process, ensuring that the radiated noise generated by the transceiver's Bluetooth signal transmission meets a first condition. The Bluetooth connection establishment process includes different stages (e.g., query, query scan, paging, paging scan, etc.), and the steps involved in the Bluetooth connection may differ in scenarios such as initial Bluetooth connection, Bluetooth pairing, and Bluetooth reconnection. This embodiment can be applied to part or all of the process of establishing a Bluetooth connection, for example, during the Bluetooth paging page process; and / or during the Bluetooth inquiry process. Furthermore, it can be applied to part or all of the process of re-establishing a Bluetooth connection after an abnormal Bluetooth connection interruption. In this case, Bluetooth may be interfered with (e.g., by body obstruction), or it may be interfered with by distance (e.g., by being far from the audio source device), or it may be caused by other abnormal reasons that lead to the Bluetooth connection interruption during use. At this time, the headset will re-establish the Bluetooth connection, for example, by entering the paging state and transmitting ID packets based on the frequency hopping protocol (i.e., during the Bluetooth paging page process of re-establishing the Bluetooth connection after an abnormal Bluetooth connection interruption). Since Bluetooth signals (e.g., ID packets) will be transmitted for a certain period of time on certain frequency bands and the rapid switching of frequency bands will cause current fluctuations and other problems, resulting in background noise (radiated noise). At this time, the processor controls the transceiver to transmit Bluetooth signals according to the preset transmission power, thereby controlling the radiated noise generated by transmitting Bluetooth signals by controlling the Bluetooth transmission power, so as to meet the first condition and thus control the impact of background noise on the user. Of course, in some cases, the headphones need to be in a polling state during the connection process. In this state, Bluetooth signals need to be transmitted across various frequency bands, which may generate radiated noise. To reduce noise, the transceiver can be controlled to transmit Bluetooth signals at a preset transmission power. For ease of control, the processor can also control the transceiver to transmit Bluetooth signals at the preset transmission power throughout the entire Bluetooth connection establishment process.

[0079] Understandably, the preset transmission power differs from the Bluetooth transmission power of the headset after establishing a Bluetooth connection. In other words, during part or all of the Bluetooth connection establishment process, the processor can adjust the Bluetooth transmission power to a preset transmission power. This preset transmission power may differ from the transmission power used when sending Bluetooth data during the Bluetooth connection state, thus enabling control of Bluetooth radiated noise in specific scenarios. Generally, the preset transmission power can be lower than the Bluetooth transmission power of the Bluetooth device after establishing a Bluetooth connection, thereby reducing Bluetooth radiated noise generated during the connection process (especially during Bluetooth paging or querying).

[0080] In this embodiment, during part or all of the Bluetooth connection establishment process, the earphone processor controls the earphone transceiver to transmit Bluetooth signals according to a preset transmission power, such that the radiated noise generated by the transceiver transmitting the Bluetooth signal satisfies a first condition. The first condition can be characterized as follows: the radiated noise generated by the earphone when transmitting the Bluetooth signal is very weak, to the point that the human ear can barely perceive it; or, the first condition can be that the radiated noise generated by the earphone when transmitting the Bluetooth signal can be perceived by the user, but the degree of perception is very weak (e.g., weaker than a specific threshold, which can be set as needed and may be affected by individual perception differences). Alternatively, the first condition can also include some radiated noise parameters to measure the generated radiated noise. For example, the parameter can include a radiated noise intensity (unit: decibel) threshold. If, during part or all of the Bluetooth connection establishment process, the intensity of the radiated noise generated when transmitting the Bluetooth signal is controlled to be less than this intensity threshold, the radiated noise generated when transmitting the Bluetooth signal is insufficient to be perceived by the user, or the radiated noise generated when transmitting the Bluetooth signal is somewhat perceived by the user, but the perceived radiated noise is very weak and will not affect the performance of the Bluetooth device.

[0081] It should be noted that the aforementioned first condition may vary depending on the usage scenario of the headphones. When using headphones in a noisy environment, the requirement for radiated noise can be relatively low; when using headphones in a quiet environment, the requirement for radiated noise can be relatively high. For example, when elderly people use headphones, the requirement for radiated noise can be relatively low, meaning the preset transmission power can be controlled to be relatively high. Although the generated radiated noise will be greater, it will be less noticeable to the user due to the noisy environment. When adults use headphones, the requirement for radiated noise can be relatively high, meaning the preset transmission power needs to be controlled to be relatively low in a quiet environment, so that no radiated noise is generated or the generated radiated noise is not noticeable to the user. For example, when elderly people use Bluetooth headphones, the requirement for radiated noise can be relatively low, as their sound perception is weaker, so a higher transmission power is permissible, and even if the generated radiated noise is slightly greater, it will not affect the use. However, when young people or adults use Bluetooth headphones, the requirement for radiated noise can be relatively high to avoid excessive noise affecting the user experience. This application does not impose any limitations.

[0082] In the aforementioned headphones, during part or all of the Bluetooth connection establishment process, the headphones transmit Bluetooth signals according to a preset transmission power, ensuring that the radiated noise generated by the transmitted Bluetooth signal meets the first condition. Since the preset transmission power ensures that the radiated noise generated by the transmitted Bluetooth signal meets the first condition, that is, the radiated noise generated by the transmitted Bluetooth signal is insufficient to be perceived by the user or is very weak (weaker than a specific threshold, which can be set as needed and may also be affected by individual differences in perception), the preset transmission power must ensure that the headphones consume less power when transmitting Bluetooth signals, thereby reducing the current fluctuations generated by the headphones and reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones.

[0083] In one embodiment, in which the processor of the aforementioned earphone controls the transceiver of the earphone to transmit a Bluetooth signal according to a preset transmission power during part or all of the process of establishing a Bluetooth connection, such that the radiated noise generated by the transmitted Bluetooth signal satisfies a first condition, the first condition characterizes the degree to which the radiated noise is perceived by the user.

[0084] In this embodiment, the first condition described above characterizes the degree to which the radiated noise generated by the Bluetooth signal transmitted by the headphones is perceived by the user. Optionally, the first condition can characterize the degree to which the intensity of the radiated noise generated by the Bluetooth signal transmitted by the headphones is perceived by the user. The degree to which it is perceived by the user can include being imperceptible or very weak (weaker than a specific threshold, which can be set as needed and may be affected by individual differences in perception). For example, typically 1 decibel is the sound that the human ear can just barely hear, and sounds below 20 decibels are generally considered quiet. Therefore, radiated noise below 1 decibel is insufficient for the user to perceive, and sounds between 1 and 20 decibels can be considered to be very weakly perceived by the user. This embodiment is not limited to this. It is understood that due to individual differences, the degree to which radiated noise is perceived by the user will also vary. For example, users of different age groups can be pre-selected in different environments to test their perception of radiated noise in various environments. Alternatively, a device simulating the human ear can be used to measure the level of radiated noise perceived by the simulated human ear in different environments, thereby determining the degree to which users perceive the radiated noise generated when the headphones transmit Bluetooth signals in various scenarios. Understandably, since each user's perception level may differ, the first condition of user perception level can also be expressed as controlling the radiated noise to a level that most users cannot perceive. For example, out of 100 randomly selected users, more than 50 should not perceive it; the specific percentage can be adjusted according to the product's performance requirements.

[0085] In this embodiment, since the first condition characterizes the degree to which the radiated noise generated by the earphone transmitting Bluetooth signals is perceived by the user, and the radiated noise generated by the earphone transmitting Bluetooth signals satisfies the first condition, that is, the radiated noise generated by the earphone when transmitting Bluetooth signals is within the acceptable range perceived by the user. In this case, the power consumed by the earphone when transmitting Bluetooth signals is small, thereby reducing the current fluctuation generated by the earphone, thereby reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones, that is, reducing the interference of the earphone on sensitive devices such as speakers and microphones when transmitting Bluetooth connection request signals.

[0086] In another embodiment, where the processor of the aforementioned headphones controls the transceiver of the headphones to transmit Bluetooth signals according to a preset transmission power during part or all of the process of establishing a Bluetooth connection, the intensity of the radiated noise generated by the transceiver transmitting the Bluetooth signal is related to the transmission power of the headphones and the device parameters of the headphones.

[0087] In this embodiment, the intensity of the radiated noise generated by the transceiver of the headphones transmitting Bluetooth signals is correlated with the transmission power of the headphones and the device parameters of the headphones. Optionally, the device parameters of the headphones include at least one of the following: the sensitivity of the headphone's speaker, the distance between the speaker and the battery, and the efficiency of the antenna. Optionally, the correlation between the intensity of the radiated noise generated by the transceiver of the headphones transmitting Bluetooth signals and the transmission power of the headphones and the device parameters of the headphones includes at least one of the following: the sensitivity of the headphone's speaker is positively correlated with the intensity of the radiated noise; the distance between the headphone's speaker and the battery is negatively correlated with the intensity of the radiated noise; the efficiency of the headphone's antenna is positively correlated with the intensity of the radiated noise; and the transmission power of the headphones is positively correlated with the intensity of the radiated noise. Understandably, the sensitivity of a headphone speaker is positively correlated with the intensity of radiated noise; that is, the higher the speaker sensitivity, the greater the radiated noise intensity, and vice versa. The distance between the speaker and battery is negatively correlated with the intensity of radiated noise; the greater the distance, the weaker the radiated noise, and vice versa. The efficiency of the headphone antenna is positively correlated with the intensity of radiated noise; the higher the antenna efficiency, the stronger the radiated noise, and vice versa. Finally, the transmit power of the headphone is positively correlated with the intensity of radiated noise; the higher the transmit power, the greater the radiated noise, and vice versa.

[0088] The earphones provided in this application embodiment are implemented by referring to the above-described Bluetooth connection method embodiment, and will not be repeated here.

[0089] In this embodiment, the intensity of the radiated noise generated by the transceiver of the earphone transmitting Bluetooth signals is related to the transmission power of the earphone and the device parameters of the earphone. Therefore, Bluetooth earphones with different device parameters may generate different radiated noises during Bluetooth connection. Due to the influence of device structure design, these device parameters are often difficult to adjust, especially for small devices like Bluetooth earphones, where the space for adjusting device parameters is limited. Therefore, adjusting the Bluetooth transmission power is used to control the noise radiation during part or all of the Bluetooth connection establishment process, solving the background noise problem from other angles and improving the product performance of Bluetooth devices.

[0090] In one embodiment, a Bluetooth headset is also provided, comprising: a processor, a transceiver connected to the processor, a speaker, and a battery;

[0091] The processor is configured to control the Bluetooth transceiver to adjust its transmit power to a preset transmit power; the Bluetooth transceiver is configured to transmit Bluetooth signals at the preset transmit power during a Bluetooth paging page, such that the radiated noise generated by the speaker satisfies a first condition.

[0092] In this embodiment, the Bluetooth headset's processor is configured to control the Bluetooth transceiver's transmit power to adjust to a preset transmit power. The Bluetooth transceiver is configured to transmit Bluetooth signals at the preset transmit power during the Bluetooth paging page process, so that the radiated noise generated by the speaker meets the first condition. Further, this could occur during the Bluetooth paging page process after an abnormal Bluetooth connection interruption. In this case, Bluetooth might be interfered with (e.g., by a body blocking the connection), or by distance interference (e.g., being far from the audio source device), or by other abnormal reasons causing the Bluetooth connection to be interrupted during use. In this situation, the Bluetooth headset will re-enter the paging state and transmit ID packets based on a frequency hopping protocol. Because transmitting Bluetooth signals (e.g., ID packets) for a certain period of time in certain frequency bands and rapidly switching frequency bands can cause current fluctuations, resulting in background noise (radiated noise). At this time, the Bluetooth headset transmits Bluetooth signals according to the preset transmit power, thereby controlling the radiated noise generated by transmitting Bluetooth signals to meet the first condition, and thus controlling the impact of background noise on the user. It is understood that the preset transmit power is different from the Bluetooth transmit power of the Bluetooth headset after establishing a Bluetooth connection. In other words, during the Bluetooth paging process described above, the Bluetooth transmission power can be adjusted to a preset transmission power. This preset transmission power can be different from the transmission power used when sending Bluetooth data during a Bluetooth connection, thus enabling the control of Bluetooth radiated noise in specific scenarios. Generally, the preset transmission power can be lower than the Bluetooth transmission power of the Bluetooth headset after establishing a Bluetooth connection, thereby reducing Bluetooth radiated noise generated during the connection process (especially during Bluetooth paging or querying).

[0093] In this embodiment, the processor of the Bluetooth headset is configured to control the transmission power of the Bluetooth transceiver to adjust to a preset transmission power. The Bluetooth transceiver is configured to transmit Bluetooth signals at this preset transmission power during Bluetooth paging, so that the radiated noise generated by the speaker of the Bluetooth headset satisfies a first condition. The first condition can be characterized as follows: the radiated noise generated by the Bluetooth headset when transmitting Bluetooth signals is very weak, to the point that the human ear can barely perceive it; or, the first condition can be that the radiated noise generated by the Bluetooth headset when transmitting Bluetooth signals can be perceived by the user, but to a very weak degree. Alternatively, the first condition may include some parameters of radiated noise, using noise parameters to measure the generated radiated noise. For example, the parameter may include a radiated noise intensity threshold. When the intensity of the radiated noise generated when transmitting Bluetooth signals is controlled within a range below this intensity threshold, the radiated noise generated when transmitting Bluetooth signals is insufficient to be perceived by the user, or the radiated noise generated when transmitting Bluetooth signals is perceived by the user, but the perceived radiated noise is very weak and will not affect the performance of the Bluetooth headset.

[0094] It should be noted that the aforementioned first condition may differ depending on the usage scenario of the Bluetooth headset. When using the headset in a noisy environment, the first condition regarding the control of radiated noise can be relatively lower; when using the headset in a quiet environment, the first condition regarding the control of radiated noise can be relatively higher. For example, when elderly people use the headset, the first condition regarding the control of radiated noise can be relatively lower, while when adults use the headset, the first condition regarding the control of radiated noise can be relatively higher. This application does not impose any limitations on this aspect.

[0095] In the aforementioned Bluetooth headset, the processor is configured to control the transmission power of the Bluetooth transceiver to adjust to a preset transmission power. The Bluetooth transceiver is configured to transmit Bluetooth signals at the preset transmission power during Bluetooth paging, so that the radiated noise generated by the speaker meets a first condition. Since the Bluetooth headset transmits Bluetooth signals at the adjusted preset transmission power, the radiated noise generated by the transmitted Bluetooth signal can meet the first condition. Since the preset transmission power can ensure that the radiated noise generated by the transmitted Bluetooth signal meets the first condition, that is, the radiated noise generated by the transmitted Bluetooth signal is insufficient to be perceived by the user or is very weak (weaker than a specific threshold), the preset transmission power needs to ensure that the Bluetooth headset consumes less power when transmitting Bluetooth signals, thereby reducing the current fluctuations generated by the Bluetooth headset and reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones.

[0096] In the scenario where the processor of the aforementioned Bluetooth headset is configured to control the transmission power of the Bluetooth transceiver to adjust to a preset transmission power, it should be noted that the preset transmission power can be determined by the Bluetooth device itself or by a designated Bluetooth device. This designated Bluetooth device can be the aforementioned Bluetooth device or a Bluetooth device with the same performance as the aforementioned Bluetooth device, such as an engineering prototype or a trial production prototype. After the preset transmission power is determined through testing, it is set in the aforementioned Bluetooth device during mass production. Alternatively, it can be determined according to user needs after the Bluetooth device leaves the factory; the principle is the same, and this application does not impose any restrictions on this. In this embodiment, before the Bluetooth transceiver is configured to transmit Bluetooth signals at the preset transmission power during Bluetooth paging, the preset transmission power needs to be determined first, so that the radiated noise generated by the Bluetooth signal emitted by the speaker of the Bluetooth headset satisfies the aforementioned first condition. Optionally, the preset transmission power can be obtained through testing before the Bluetooth headset leaves the factory. It can be determined through manual or machine testing. For example, a specified Bluetooth headset can adjust its current Bluetooth transmission power. During a Bluetooth paging process, if the radiated noise generated by transmitting a Bluetooth signal at the current Bluetooth transmission power meets a first condition, the current Bluetooth transmission power is determined as the preset transmission power. Typically, the Bluetooth transmission power of a Bluetooth headset is 0dBm to 10dBm. The Bluetooth headset can adjust its Bluetooth transmission power starting from 0dBm using preset frequency adjustment intervals. When the radiated noise generated by the speaker transmitting a Bluetooth signal meets the first condition, the current Bluetooth transmission power is determined as the preset transmission power. For example, taking a preset frequency adjustment interval of 2dBm, the Bluetooth headset starts at 10dBm and adjusts its Bluetooth transmission power at 2dBm intervals. When the Bluetooth transmission power is adjusted to 4dBm, the radiated noise generated by transmitting a Bluetooth signal meets the first condition, and the Bluetooth headset determines the current transmission power of 4dBm as the preset transmission power. This embodiment is not limited to this.

[0097] In some embodiments, since there may be multiple preset transmission powers that make the radiated noise meet the first condition, for example, within a certain range, but some transmission powers may be too low and may be detrimental to Bluetooth connectivity, it is also necessary to consider the performance of Bluetooth connectivity. Bluetooth connectivity performance can be measured by methods such as Bluetooth connection speed at a specific distance. For example, Bluetooth connectivity performance can include whether the Bluetooth headset can meet the connection requirements when connecting within a specific distance, or whether the Bluetooth headset can meet the requirements for connection speed and connection time when connecting within a specific distance. Therefore, a specified Bluetooth headset can determine the preset transmission power based on the radiated noise generated by its transmitted Bluetooth connection signal and the preset Bluetooth connectivity performance. This preset Bluetooth connectivity performance can be determined based on product requirements, user experience, etc. For example, determining the preset transmission power includes: adjusting the current Bluetooth transmission power of the specified Bluetooth headset; when the radiated noise generated by transmitting the Bluetooth signal (the Bluetooth signal during the Bluetooth paging process) at the current Bluetooth transmission power meets the first condition and the preset Bluetooth connectivity performance, the current Bluetooth transmission power is used as the preset transmission power. The preset Bluetooth connection performance can be determined by the Bluetooth connection speed at a specific distance. For example, if the Bluetooth connection speed of the Bluetooth headset within a specific distance meets the preset speed requirement, then the Bluetooth connection speed can be determined as the preset Bluetooth connection performance.

[0098] Understandably, the preset transmit power is determined based on radiated noise; or, the preset transmit power is determined based on radiated noise and preset Bluetooth connectivity performance.

[0099] It's understandable that the preset transmission power is lower than the Bluetooth transmission power of the Bluetooth headset after establishing a Bluetooth connection.

[0100] Understandably, to ensure that the radiated noise generated by the loudspeaker satisfies the first condition, the following conditions must be met:

[0101] The intensity of the radiated noise is less than the intensity of the reference radiated noise, which is the intensity of the radiated noise generated by the speaker when the Bluetooth transceiver transmits the Bluetooth signal at the Bluetooth transmission power in the Bluetooth connection state during part or all of the Bluetooth connection establishment process.

[0102] The Bluetooth headset provided in this application embodiment is implemented by referring to the above-described Bluetooth connection method embodiment, and will not be repeated here.

[0103] In this embodiment, the Bluetooth transceiver of the Bluetooth headset is configured to determine the preset transmission power before transmitting the Bluetooth signal during the Bluetooth paging page process. This ensures that the Bluetooth transceiver of the Bluetooth headset transmits the Bluetooth signal at the preset transmission power during part or all of the Bluetooth connection establishment process, so that the radiated noise generated by transmitting the Bluetooth signal meets the first condition. This ensures that the power consumed by the Bluetooth headset when transmitting the Bluetooth signal is small, thereby reducing the current fluctuation generated by the Bluetooth headset and reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones.

[0104] It should be understood that, although Figure 2-3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 2-3 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.

[0105] In one embodiment, such as Figure 5 As shown, a Bluetooth connection device is provided, including: a processing module 10 and a transmitting module 11 (which may include a transceiver module with transceiver functions), wherein:

[0106] Processing module 10 is used to control the transmitting module 11 to transmit Bluetooth signals according to a preset transmission power during part or all of the process of establishing a Bluetooth connection, so that the radiated noise generated by transmitting the Bluetooth signal satisfies a first condition.

[0114] Optionally, the above correlation includes at least one of the following:

[0115] Sensitivity is positively correlated with the intensity of radiated noise;

[0116] Distance is negatively correlated with the intensity of radiated noise;

[0118] The transmission power is positively correlated with the intensity of radiated noise.

[0119] The Bluetooth connection device provided in this embodiment can execute the above method embodiment, and its implementation principle and technical effect are similar, so they will not be described again here.

[0120] Based on the above embodiments, optionally, the processing module 10 is used to make the intensity of the radiated noise less than the intensity of the reference radiated noise, the intensity of the reference radiated noise being the intensity of the radiated noise generated by transmitting Bluetooth signals according to the Bluetooth transmission power in the Bluetooth connection state during part or all of the process of establishing a Bluetooth connection.

[0121] Based on the above embodiments, optionally, the processing module 10 is specifically used to make the intensity of the radiated noise generated by transmitting the Bluetooth signal less than or equal to the reference value of the minimum radiated noise that can be perceived by the human ear.
