Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
本申请提供的蓝牙连接方法,可以应用于如图1所示的应用环境中。其中,蓝牙设备102通过蓝牙与蓝牙设备104进行通信,例如蓝牙设备102为第一蓝牙耳机、蓝牙设备104为第二耳机或手机,其中第一蓝牙耳机与第二蓝牙耳机可以是TWS(True Wireless Stereo真无线立体声)蓝牙耳机的左右耳机。蓝牙设备102以及蓝牙设备104均可以包括天线、喇叭、麦克风、蓝牙主控电路和电池等,当蓝牙设备102与蓝牙设备104进行配对或者回连时,蓝牙设备102与蓝牙设备104之间通过蓝牙信号进行蓝牙连接。蓝牙设备蓝牙信号可以是蓝牙标准中进行蓝牙连接过程中蓝牙收发器发送的任意信号,也可以是其中某些状态下发射的信号,例如蓝牙寻呼(Page)状态、蓝牙查询(inquiry)状态或蓝牙响应(response)状态发射的蓝牙信号等,比如蓝牙寻呼状态发射的ID包。经发明人分析发现,在蓝牙连接过程中,特别是寻呼状态或查询状态下,由于会基于跳频协议在各种频段发射ID包等信息包,会有较大的电流波动,容易引起蓝牙设备的电磁辐射对喇叭、麦克风等敏感器件产生干扰,例如,由于电流波动导致的电源(如电池)产生电磁场,电磁场的电磁辐射会对喇叭等敏感器件产生干扰,从而引起底噪(如电流声),特别是对于蓝牙耳机这种结构紧凑的设备,由于各器件位置紧密产生的干扰影响更明显,从而影响用户的使用感受。The Bluetooth connection method provided in this application can be applied to the application environment shown in FIG. 1 . The Bluetooth device 102 communicates with the Bluetooth device 104 through Bluetooth, for example, the Bluetooth device 102 is a first Bluetooth headset, and the Bluetooth device 104 is a second headset or a mobile phone, wherein the first Bluetooth headset and the second Bluetooth headset can be TWS (True Wireless Stereo True Wireless Stereo) Left and Right Headphones for Bluetooth Headphones. Both the Bluetooth device 102 and the Bluetooth device 104 may include an antenna, a speaker, a microphone, a Bluetooth main control circuit, and a battery. signal for Bluetooth connection. The bluetooth signal of a bluetooth device can be any signal sent by the bluetooth transceiver during the bluetooth connection in the bluetooth standard, or it can be a signal transmitted in some of the states, such as the bluetooth paging (Page) state, the bluetooth inquiry (inquiry) state or The Bluetooth signal transmitted in the Bluetooth response state, etc., such as the ID packet transmitted in the Bluetooth paging state. The inventor's analysis found that during the Bluetooth connection process, especially in the paging state or the query state, since the ID packets and other information packets will be transmitted in various frequency bands based on the frequency hopping protocol, there will be large current fluctuations, which is easy to cause Bluetooth. The electromagnetic radiation of the device interferes with sensitive devices such as speakers and microphones. For example, the power supply (such as batteries) caused by current fluctuations generates an electromagnetic field, and the electromagnetic radiation of the electromagnetic field will interfere with sensitive devices such as speakers, resulting in noise floor (such as current sound.) ), especially for a device with a compact structure such as a Bluetooth headset, the interference effect caused by the close position of each device is more obvious, thereby affecting the user's experience of use.
因此,为了解决上述问题,在一个实施例中,如图2所示,提供了一种蓝牙连接方法,以该方法应用于图1中的蓝牙设备为例进行说明,包括以下步骤:Therefore, in order to solve the above problems, in one embodiment, as shown in FIG. 2, a Bluetooth connection method is provided, and the method is applied to the Bluetooth device in FIG. 1 as an example for description, including the following steps:
S201,在建立蓝牙连接的部分或全部过程中,蓝牙设备根据预设发射功率发射蓝牙信号,使得发送蓝牙信号产生的辐射噪声满足第一条件。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, so that the radiation noise generated by the transmission of the Bluetooth signal satisfies the first condition.
可以理解的,建立蓝牙连接的过程包括不同的阶段(例如可以包括查询、查询扫描、寻呼、寻呼扫描等状态),在蓝牙首次连接、蓝牙配对和蓝牙回连等场景中,蓝牙连接包括的步骤可能不同。该实施例,可以应用在建立蓝牙连接的部分或全部过程中,例如,该蓝牙连接方法可以应用在蓝牙寻呼page过程中;和/或,在蓝牙查询inquiry过程中,进一步的,可以是在蓝牙连接非正常中断后重新建立蓝牙连接的部分或全部过程中;这种情况下,可能是蓝牙受到干扰(如身体遮挡等),也可以是受到距离干扰(如离音源设备距离较远),还可以是其他非正常的原因导致在使用过程中发生蓝牙连接中断,此时蓝牙设备会重新进行蓝牙连接,例如进入寻呼状态,基于跳频协议发射ID包(即在蓝牙连接非正常中断后重新建立蓝牙连接的蓝牙寻呼page过程中),由于会在某些频段持续一定时间发送蓝牙信号并且快速切换频段发射等会导致电流波动等问题,从而产生底噪(辐射噪声), 此时,蓝牙设备根据预设发射功率发射蓝牙信号,从而通过控制蓝牙发射功率来控制发送蓝牙信号产生的辐射噪声,使其满足第一条件,进而控制底噪对用户的影响。当然,在有些情况下,蓝牙设备在连接过程中还需要处于查询状态,查询状态下也需要在各种频带发射蓝牙信号,因此可能产生辐射噪声,为了降低噪声,也可以采用调整至预设发射功率的方式来发射蓝牙信号。为了方便控制,也可以在建立蓝牙连接的整个过程中均采用预设发射功率来发射蓝牙信号。It can be understood that the process of establishing a Bluetooth connection includes different stages (for example, it may include states such as inquiry, inquiry scanning, paging, and paging scanning). steps may vary. This embodiment may be applied in part or all of the process of establishing a Bluetooth connection. For example, the Bluetooth connection method may be applied in a Bluetooth paging page process; and/or in a Bluetooth inquiry process, further, it may be in Part or all of the process of re-establishing the Bluetooth connection after the Bluetooth connection is abnormally interrupted; in this case, the Bluetooth may be interfered (such as body occlusion, etc.), or it may be interfered by distance (such as the distance from the audio source device), It can also be other abnormal reasons that cause the Bluetooth connection to be interrupted during use. At this time, the Bluetooth device will reconnect to the Bluetooth connection, such as entering the paging state, and transmit ID packets based on the frequency hopping protocol (that is, after the Bluetooth connection is abnormally interrupted. During the bluetooth paging page process of re-establishing the bluetooth connection), since the bluetooth signal will be sent in some frequency bands for a certain period of time, and the rapid switching of frequency bands will cause problems such as current fluctuations, resulting in noise floor (radiation noise), at this time, The Bluetooth device transmits the Bluetooth signal according to the preset transmission power, so as to control the radiation noise generated by the transmission of the Bluetooth signal by controlling the Bluetooth transmission power, so that the first condition is satisfied, and then the influence of the noise floor on the user is controlled. Of course, in some cases, the Bluetooth device still needs to be in the query state during the connection process. In the query state, it also needs to transmit Bluetooth signals in various frequency bands, so radiation noise may be generated. In order to reduce the noise, it can also be adjusted to the preset transmission. power to transmit bluetooth signals. For the convenience of control, the preset transmission power may also be used to transmit the Bluetooth signal during the whole process of establishing the Bluetooth connection.
可以理解的,预设发射功率与蓝牙设备在建立蓝牙连接后的蓝牙发射功率不同。也就是说在上述建立蓝牙连接的部分或全部过程中,可以将蓝牙发送功率调整到预设发射功率,该预设发射功率与蓝牙连接状态下发送蓝牙数据时的发射功率可以不相同,从而能够实现特定场景下控制蓝牙辐射噪声的作用。一般来说,预设发射功率可以小于蓝牙设备在建立蓝牙连接后的蓝牙发射功率,从而降低在连接过程(特别是蓝牙寻呼或查询过程中)中产生的蓝牙辐射噪声。在本实施例中,蓝牙设备在建立蓝牙连接的部分或全部过程中,根据预设发射功率发射蓝牙信号,使得发送该蓝牙信号产生的辐射噪声满足第一条件。其中,第一条件表征辐射噪声被用户感知的程度。可以理解的,由于人耳对声音感知存在差异,因此对辐射噪声的感知程度也存在个体差异,为了控制蓝牙设备在连接过程中产生的辐射噪声对用户的影响,第一条件可以是用户完全感知不到该辐射噪声的情况,这种情况下可能没有辐射噪声,或者产生的辐射噪声弱用户感知不到;也可以是用户能够感知的辐射噪声小于预定值的情况,使得辐射噪声较小对用户影响弱,从而兼顾连接效率和辐射噪声对用户的影响。具体的,第一条件可以表征为蓝牙设备在发射蓝牙信号时消耗的功率较小,电流的波动较小,产生的辐射噪声较弱,以蓝牙设备为蓝牙耳机为例,在蓝牙耳机与其他蓝牙设备建立连接的过程中,第一条件可以为蓝牙耳机在发射蓝牙信号时产生的辐射噪声很弱,人耳基本感觉不到该辐射噪声,或者,第一条件可以为蓝牙耳机在发射蓝牙信号时产生的辐射噪声可以被用户感知到,但感知的程度很弱。由于不同的用户个体感知能力的差异,导致同一种情况下,可能有的用户能够感知有的用户不能够感知,因此该第一条件可以包括一些辐射噪声的参数,用噪声参数来衡量产生的辐射噪声的情况,例如,该参数可以包括辐射噪声的强度(单位“分贝”)阈值,则在建立蓝牙连接的部分或全部过程中,发射蓝牙信号时产生的辐射噪声的强度控制在小于该强度阈值的范围内时,可以使得发射蓝牙信号时产生的辐射噪声不被用户感知,或者,使得发射蓝牙信号时产生的辐射噪声能够被用户感知到,但用户感知到的辐射噪声很弱,不会影响蓝牙设备的使用性能。It can be understood that the preset transmission power is different from the Bluetooth transmission power of the Bluetooth device after the Bluetooth connection is established. That is to say, in part or all of the above process of establishing a Bluetooth connection, the Bluetooth transmission power can be adjusted to a preset transmission power, which can be different from the transmission power when the Bluetooth data is sent in the Bluetooth connection state, so that the Bluetooth transmission power can be adjusted to a preset transmission power. Realize the role of controlling Bluetooth radiation noise in specific scenarios. Generally speaking, the preset transmit power may be lower than the Bluetooth transmit power of the Bluetooth device after the Bluetooth connection is established, thereby reducing the Bluetooth radiation noise generated during the connection process (especially during the Bluetooth paging or inquiry process). In this embodiment, the Bluetooth device transmits the Bluetooth signal according to the preset transmission power during part or all of the process of establishing the Bluetooth connection, so that the radiation noise generated by the transmission of the Bluetooth signal satisfies the first condition. The first condition represents the degree to which the radiated noise is perceived by the user. It is understandable that due to the differences in the human ear's perception of sound, there are also individual differences in the perception of radiated noise. In order to control the impact of the radiated noise generated by the Bluetooth device during the connection process on the user, the first condition can be that the user can fully perceive it. In this case, there may be no radiated noise, or the generated radiated noise is weak and the user cannot perceive it; it can also be a situation where the radiated noise that the user can perceive is less than a predetermined value, so that the radiated noise is small for the user. The impact is weak, so as to take into account the impact of connection efficiency and radiation noise on users. Specifically, the first condition can be characterized as the power consumption of the Bluetooth device when transmitting the Bluetooth signal is small, the current fluctuation is small, and the radiation noise generated is weak. In the process of establishing a connection between the devices, the first condition may be that the radiation noise generated by the Bluetooth headset when transmitting a Bluetooth signal is very weak, and the radiated noise is basically not felt by the human ear, or the first condition may be that the Bluetooth headset is transmitting a Bluetooth signal. The resulting radiated noise can be perceived by the user, but to a very weak degree. Due to the difference in the individual perception capabilities of different users, some users may be able to perceive and some users may not be able to perceive in the same situation. Therefore, the first condition may include some parameters of radiated noise, and the noise parameters are used to measure the generated radiation. In the case of noise, for example, this parameter may include a threshold value of the intensity of radiated noise (unit "decibel"), then during part or all of the process of establishing a Bluetooth connection, the intensity of radiated noise generated when transmitting a Bluetooth signal is controlled to be less than the intensity threshold. Within the range, the radiated noise generated when the Bluetooth signal is transmitted can be prevented from being perceived by the user, or the radiated noise generated when the Bluetooth signal is transmitted can be perceived by the user, but the radiated noise perceived by the user is very weak and will not affect the The performance of the Bluetooth device.
需要说明的是,蓝牙设备在不同的使用场景中,对应的上述第一条件也可以是不同的,以蓝牙设备为蓝牙耳机为例,在嘈杂的环境中使用蓝牙耳机时,第一条件对于辐射噪声的控制要求可以相对较低,也就是说可以控制预设发射功率相对高一些,虽然产生的辐射噪声会大一些,但是由于环境嘈杂,用户不易感知;在安静环境中使用蓝牙耳机时,第一条件对于辐射噪声的控制要求可以相对较高,也就是说安静环境下需要控制预设发射功率相对低一些,从而不产生辐射噪声或者产生的辐射噪声不被用户感知;又例如,老年人使用蓝牙耳机时,第一条件对于辐射噪声的控制要求可以相对较低,老年人对声音感知较弱,因此允许提升发射功率,即使产生的辐射噪声稍大也不影响使用;而对于青年或成年人使用蓝牙耳机时,第一条件对于辐射噪声的控制要求可以相对较高,避免过大噪声影响用户体验。本申请实施例中不加以限制。It should be noted that in different usage scenarios of the Bluetooth device, the corresponding first condition may also be different. Taking the Bluetooth device as a Bluetooth headset as an example, when the Bluetooth headset is used in a noisy environment, the first condition affects the radiation The noise control requirements can be relatively low, that is to say, the preset transmission power can be controlled to be relatively high, although the radiation noise generated will be larger, but due to the noisy environment, the user is not easy to perceive; when using a Bluetooth headset in a quiet environment, the first For one condition, the control requirements for radiated noise can be relatively high, that is to say, the preset transmit 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 perceived by the user; When using a Bluetooth headset, the first condition requires relatively low control of radiated noise, and the elderly have weaker perception of sound, so it is allowed to increase the transmission power, even if the radiated noise generated is slightly larger, it will not affect the use; while for young people or adults When using a Bluetooth headset, the first condition may have relatively high control requirements for radiated noise, so as to avoid excessive noise affecting user experience. No limitation is imposed in the embodiments of the present application.
在上述使蓝牙设备发送的蓝牙信号产生的辐射噪声满足第一条件的场景中,第一条件可以是辐射噪声的强度小于参考辐射噪声的强度,该参考辐射噪声的强度为在建立蓝牙连接的部分或全部过程中,按照蓝牙连接状态下的蓝牙发射功率发射所述蓝牙信号产生的辐射噪声强度。In the above scenario where the radiation noise generated by the Bluetooth signal sent by the Bluetooth device satisfies the first condition, the first condition may be that the intensity of the radiation noise is less than the intensity of the reference radiation noise, and the reference radiation noise intensity is the part of the Bluetooth connection that is established. Or in the whole process, the radiation noise intensity generated by the bluetooth signal is transmitted according to the bluetooth transmission power in the bluetooth connection state.
可以理解的,该实施例中,以蓝牙耳机为例,如果以蓝牙连接状态下的蓝牙发射功率进行蓝牙连接或者在寻呼状态下发射蓝牙信号,用户在佩戴该蓝牙耳机的情况下,能够感知到辐射噪声(即参考辐射噪声);而其他条件相同的情况下将上述蓝牙发射功率调整为预设发射功率进行发射,则该用户感知不到辐射噪声(底噪)或者感知到的辐射噪声强度要小于上述参考辐射噪声的强度(因为可能有其他原因产生的底噪或并没有完全消除因蓝 牙发射产生的底噪,仅仅是降低了辐射噪声)。在一个实施例中,第一条件表征辐射噪声被用户感知的程度。在本实施例中,上述第一条件表征蓝牙设备发送蓝牙信号产生的辐射噪声被用户感知的程度。可选的,该第一条件可以表征蓝牙设备发送蓝牙信号产生的辐射噪声的强度被用户感知的程度。其中,被用户感知的程度可以包括不足以被用户感知或者被用户感知的程度很弱(弱于特定的阈值,该特定的阈值可以根据需要设置,也可能受个体感知差异影响),例如,通常情况下,1分贝是人类耳朵刚刚能听到的声音,20分贝以下的声音,一般来说,可以认为它是安静的,那么,1分贝以下的辐射噪声是不足以被用户感知的,1分贝到20分贝之间的声音可以认为被用户感知的程度很弱,本申请实施例中并不以次为限。可以理解的是,由于个体间的差异,辐射噪声被用户感知的程度也会有所不同。示例性地,可以预先选择不同年龄段的用户在不同环境中,测试各个年龄段的用户在各种环境中对于辐射噪声的感知程度,或者,可以采用模拟人耳的设备,在不同的环境中对这些模拟人耳感知的辐射噪声的程度,从而确定在各种场景中蓝牙设备发射蓝牙信号时产生的辐射噪声被用户感知的程度。可以理解的,由于每个用户感知程度可能不同,因此第一条件的用户感知程度,也可以表示为将辐射噪声控制在大部分用户不能感知的条件下即可,例如100名随机用户中,超过50名感知不到,具体占比可以根据产品对性能的要求进行调整。It can be understood that in this embodiment, taking the Bluetooth headset as an example, if the Bluetooth connection is performed with the Bluetooth transmission power in the Bluetooth connection state or the Bluetooth signal is transmitted in the paging state, the user can perceive the Bluetooth headset when wearing the Bluetooth headset. radiated noise (that is, reference radiated noise); and if other conditions are the same, the above Bluetooth transmit power is adjusted to the preset transmit power for transmission, then the user cannot perceive the radiated noise (the noise floor) or the perceived intensity of the radiated noise. It should be less than the intensity of the reference radiation noise mentioned above (because there may be other reasons for the noise floor or the noise floor caused by Bluetooth transmission is not completely eliminated, but the radiation noise is only reduced). In one embodiment, the first condition characterizes the degree to which radiated noise is perceived by the user. In this embodiment, the above-mentioned first condition represents the degree to which the radiated noise generated by the Bluetooth device sending the Bluetooth signal is perceived by the user. Optionally, the first condition may represent the degree to which the intensity of radiation noise generated by the Bluetooth device sending the Bluetooth signal is perceived by the user. Wherein, the degree of perception by the user may include insufficient perception by the user or a very weak degree of perception by the user (less than a specific threshold, the specific threshold can be set according to needs, and may also be affected by individual perception differences), for example, usually In this case, 1 decibel is the sound that the human ear can just hear. Generally speaking, the sound below 20 decibels can be considered as quiet. Then, the radiated noise below 1 decibel is not enough to be perceived by the user. Sounds between 20 decibels can be considered to be very weak to be perceived by the user, which is not limited to times in the embodiments of the present application. It is understandable that, due to individual differences, the degree to which radiated noise is perceived by users will also vary. Exemplarily, users of different age groups may be preselected in different environments to test the perception level of users of different age groups to radiated noise in various environments, or a device that simulates human ears may be used in different environments. The degree of radiated noise perceived by the human ear is simulated, so as to determine the degree to which the radiated noise generated when the Bluetooth device transmits the Bluetooth signal is perceived by the user in various scenarios. It is understandable that since each user's perception level may be different, the user's perception level of the first condition can also be expressed as controlling the radiated noise under conditions that most users cannot perceive. For example, among 100 random users, more than 50 people cannot perceive it, and the specific proportion can be adjusted according to the performance requirements of the product.
本实施例中,由于第一条件表征蓝牙设备发送蓝牙信号产生的辐射噪声被用户感知的程度,而蓝牙设备发射蓝牙信号产生的辐射噪声是满足该第一条件的,也就是说蓝牙设备在发射蓝牙信号时产生的辐射噪声在用户感知的可接受范围内,即在这种情况下蓝牙设备在发射蓝牙信号时消耗的功率较小,从而使蓝牙设备产生的电流波动较弱,进而减少了电磁辐射对喇叭、麦克风等敏感器件产生的干扰影响,即减少了蓝牙设备发送蓝牙连接请求信号时对喇叭、麦克风等敏感器件产生的干扰。In this embodiment, since the first condition represents the degree to which the radiated noise generated by the Bluetooth device transmitting the Bluetooth signal is perceived by the user, the radiation noise generated by the Bluetooth device transmitting the Bluetooth signal satisfies the first condition, that is to say, the Bluetooth device is transmitting The radiation noise generated by the Bluetooth signal is within the acceptable range of the user's perception, that is, in this case, the Bluetooth device consumes less power when transmitting the Bluetooth signal, so that the current fluctuation generated by the Bluetooth device is weaker, thereby reducing electromagnetic waves. The interference effect of radiation on sensitive devices such as speakers and microphones, that is, the interference to sensitive devices such as speakers and microphones when the Bluetooth device sends a Bluetooth connection request signal is reduced.

在本实施例中,蓝牙设备根据上述预设发射功率发射的蓝牙信号,使得蓝牙设备发送蓝牙信号产生的辐射噪声的强度小于或等于人耳可感知的最小辐射噪声的参考值。其中,人耳可感知的声音频率一般在20HZ至2万HZ之间,但存在个体差异,每个人不同年龄阶段也会有差异,例如有的成年人可感知的声音频率一般为30-16000赫兹,老年人可感知的声音频率一般为50-10000赫兹,因此可以选取一个人耳可感知参考值,例如20HZ,也可以是30HZ。例如为30HZ时,有的用户可能可以感知到,但是有的用户感知的不是很明显或者有的用户感知不到。示例性地,以人耳可感知的最小辐射噪声的参考值为20HZ为例,则蓝牙设备根据上述预设发射功率发射的蓝牙信号产生的辐射噪声的强度则要小于或等于20HZ。需要说明的是,不同人群或者不同的环境中,人耳可感知的最小辐射噪声的参考值可以不同,例如,成年人可感知的最小辐射噪声的参考值是20HZ,老人可感知的最小辐射噪声的参考值是25HZ或者30HZ。最小辐射噪声的参考值的选取,可以根据产品的性能需要选择,例如选择一个最小辐射噪声的参考值可以使得大部分用户感知不到辐射噪声或感知的辐射噪声较弱,可忽略其影响等,从而提升蓝牙设备对大多数用户的适用性。In this embodiment, the bluetooth device transmits the bluetooth signal according to the preset transmission power, so that the intensity of the radiation noise generated by the bluetooth device sending the bluetooth signal is less than or equal to the reference value of the minimum radiated noise perceivable by the human ear. Among them, the sound frequency perceivable by the human ear is generally between 20 Hz and 20,000 Hz, but there are individual differences, and each person will have differences at different ages. For example, some adults can perceive the sound frequency is generally 30-16000 Hz , the sound frequency that the elderly can perceive is generally 50-10000 Hz, so a reference value that can be perceived by the human ear can be selected, such as 20HZ or 30HZ. For example, when it is 30HZ, some users may be able to perceive it, but some users may not perceive it very clearly or some users may not perceive it. Exemplarily, taking the reference value of the minimum radiated noise perceivable by 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 transmit power is less than or equal to 20 Hz. It should be noted that, in different groups of people or in different environments, the reference value of the minimum radiated noise perceivable by the human ear can be different. The reference value is 25HZ or 30HZ. The selection of the reference value of the minimum radiated noise can be selected according to the performance of the product. For example, selecting a reference value of the minimum radiated noise can make most users feel no radiated noise or the perceived radiated noise is weak, and its influence can be ignored, etc. Thereby, the applicability of the Bluetooth device to most users is improved.

The power of the Bluetooth device is relatively small, so that the current fluctuation generated by the Bluetooth device can be weaker, thereby reducing the interference effect of electromagnetic radiation on sensitive devices such as speakers and microphones, that is, reducing the impact on speakers, microphones, etc. when the Bluetooth device sends a Bluetooth connection request signal.

Among them, the absolute threshold of human hearing refers to the weakest sound felt by the human auditory system. In this embodiment, the radiation noise generated by the Bluetooth device transmitting the Bluetooth signal is less than or equal to the reference value of the absolute threshold of human hearing, that is to say, the radiation noise generated by the Bluetooth device transmitting the Bluetooth signal is less than or equal to the maximum perceived by the human auditory system. weak voice. Exemplarily, 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 is less than or equal to 19 Hz.

The degree of being perceived by the user may include a degree that is insufficient to be perceived by the user or is very weak by the user. For example, in general, 1 decibel is the sound that the human ear can just hear, and the sound below 20 decibels is generally , it can be considered as quiet, then, the radiated noise below 1 decibel is not enough to be perceived by the user, and the sound between 1 decibel and 20 decibels can be considered to be very weak by the user. limited to times. It is understandable that, due to individual differences, the degree to which radiated noise is perceived by users will also vary. Exemplarily, users of different age groups may be preselected in different environments to test the perception level of users of different age groups to radiated noise in various environments, or a device that simulates human ears may be used in different environments.

本实施例中,由于第二条件表征蓝牙设备发送蓝牙信号产生的辐射噪声的强度被用户感知的程度,而蓝牙设备发射蓝牙信号产生的辐射噪声的强度是满足该第二条件的,也就是说蓝牙设备在发射蓝牙信号时产生的辐射噪声的强度不被用户感知,或者在用户感知的可接受范围内,即在这种情况下蓝牙设备在发射蓝牙信号时消耗的功率较小,从而使蓝牙设备产生的电流波动较弱,进而减少了电磁辐射对喇叭、麦克风等敏感器件产生的干扰影响,即减少了蓝牙设备发送蓝牙连接请求信号时对喇叭、麦克风等敏感器件产生的干扰。In this embodiment, since the second condition represents the degree to which the intensity of the radiation noise generated by the Bluetooth device sending the Bluetooth signal is perceived by the user, and the intensity of the radiation noise generated by the Bluetooth device transmitting the Bluetooth signal satisfies the second condition, that is to say The intensity of the radiated noise generated by the Bluetooth device when transmitting the Bluetooth signal is not perceived by the user, or is within the acceptable range perceived by the user, that is, in this case, the Bluetooth device consumes less power when transmitting the Bluetooth signal, so that the Bluetooth The current fluctuation generated by the device is weak, thereby reducing the interference effect of electromagnetic radiation on sensitive devices such as speakers and microphones, that is, reducing the interference to sensitive devices such as speakers and microphones when the Bluetooth device sends a Bluetooth connection request signal.
在上述蓝牙设备根据预设发射功率发射蓝牙信号的场景中,重点介绍了如何使得发送蓝牙信号产生的辐射噪声满足第一条件,下面重点介绍确定该发射功率的详细过程,需要说明的是,预设发射功率可以是通过该蓝牙设备确定的,也可以是通过指定蓝牙设备确定的,该指定蓝牙设备可以是上述蓝牙设备,也可以是与上述蓝牙设备具有相同性能的蓝牙设备,例如工程样机、试量产样机等,通过测试确定出预设发射功率后,在量产时设置在上述蓝牙设备中。当然也可以在蓝牙设备出厂后根据用户需要确定,原理是相同的,本申请对此不做限制。In the above scenario where the Bluetooth device transmits the Bluetooth signal according to the preset transmission power, it focuses on how to make the radiation noise generated by the transmission of the Bluetooth signal meet the first condition. The following focuses on the detailed process of determining the transmission power. The transmission power can be determined by the Bluetooth device, or determined by the specified Bluetooth device, and the specified Bluetooth device can be the above-mentioned Bluetooth device, or it can be a Bluetooth device with the same performance as the above-mentioned Bluetooth device, such as engineering prototype, For trial mass production prototypes, etc., after the preset transmission power is determined through testing, it is set in the above-mentioned Bluetooth devices during mass production. Of course, it can also be determined according to user needs after the Bluetooth device leaves the factory. The principle is the same, which is not limited in this application.
在本实施例中,在根据该预设发射功率发射蓝牙信号之前,需要先确定该预设发射功率,使得发射蓝牙信号产生的辐射噪声满足上述第一条件。可选的,该预设发射功率可以是在蓝牙设备出厂前进行测试得到,可以是人工或者机器测试确定,例如通过调整指定蓝牙设备的当前蓝牙发射功率,当在建立蓝牙连接的部分或全部过程中,以当前蓝牙发射功率发送蓝牙信号产生的辐射噪声满足上述第一条件时,将当前蓝牙发射功率确定为上述预设发射功率。通常,蓝牙设备的蓝牙发射功率是0dbm~10dbm,蓝牙设备可以通过预设的频率调整间隔,从0dbm开始调整蓝牙设备的蓝牙发射功率,当蓝牙设备发送蓝牙信号产生的辐射噪声满足上述第一条件时,将当前的蓝牙发射功率确定为上述预设发射功率。示例性地,以预设的频率调整间隔为2dbm为例,蓝牙设备从10dbm开始,以2dbm的频率 调整间隔调整蓝牙设备的蓝牙发射功率,当调整蓝牙设备的蓝牙发射功率为4dbm时,发送蓝牙信号产生的辐射噪声满足上述第一条件,则蓝牙设备将当前的发射功率4dbm确定为上述预设发射功率,本申请实施例并不以此为限。In this embodiment, before the Bluetooth signal is transmitted according to the preset transmission power, the preset transmission power needs to be determined, so that the radiation noise generated by the transmission of the Bluetooth signal satisfies the above-mentioned first condition. Optionally, the preset transmit power may be obtained by testing the Bluetooth device before it leaves the factory, and may be determined by manual or machine testing, for example, by adjusting the current Bluetooth transmit power of the specified Bluetooth device, when part or all of the process of establishing a Bluetooth connection is performed. In the above, when the radiation noise generated by sending the Bluetooth signal with the current Bluetooth transmission power satisfies the above-mentioned first condition, the current Bluetooth transmission power is determined as the above-mentioned preset transmission power. Usually, the bluetooth transmit power of the bluetooth device is 0dbm~10dbm, the bluetooth device can adjust the bluetooth transmit power of the bluetooth device from 0dbm through the preset frequency adjustment interval, when the bluetooth device sends the bluetooth signal, the radiation noise generated by the bluetooth device meets the above first condition When the current Bluetooth transmit power is determined as the above preset transmit power. Exemplarily, taking the preset frequency adjustment interval of 2dbm as an example, the Bluetooth device starts from 10dbm and adjusts the Bluetooth transmit power of the Bluetooth device at a frequency adjustment interval of 2dbm. When the Bluetooth transmit power of the Bluetooth device is adjusted to 4dbm, the Bluetooth device sends the If the radiation noise generated by the signal satisfies the above-mentioned first condition, the Bluetooth device determines the current transmission power of 4 dbm as the above-mentioned preset transmission power, which is not limited in this embodiment of the present application.
也就是说,预设发射功率可以由指定蓝牙设备确定,该指定蓝牙设备包括上述蓝牙设备或与上述蓝牙设备性能相同的其他蓝牙设备。进一步的,预设发射功率由指定蓝牙设备确定包括:预设发射功率根据指定蓝牙设备在建立蓝牙连接的部分或全部过程中发射的所述蓝牙信号产生的辐射噪声满足上述任一第一条件时,该指定蓝牙设备对应的发射功率确定。That is to say, the preset transmit power may be determined by a designated Bluetooth device, and the designated Bluetooth device includes the above-mentioned Bluetooth device or other Bluetooth devices with the same performance as the above-mentioned Bluetooth device. Further, the determination of the preset transmission power by the designated Bluetooth device includes: when the preset transmission power satisfies any one of the above-mentioned first conditions according to the radiation noise generated by the Bluetooth signal transmitted by the designated Bluetooth device during part or all of the process of establishing the Bluetooth connection. , the transmit power corresponding to the specified Bluetooth device is determined.
为了提升该预设发射功率的通用性,示例性地,以蓝牙设备为蓝牙耳机为例,可以随机选取100名用户,调整指定蓝牙耳机的发射功率,当调整的发射功率使得发送蓝牙信号产生的辐射噪声使该100名用户中超过60名用户感知不到该辐射噪声时,将此时的发射功率确定为预设发射功率,可选的,感知不到发送蓝牙信号产生的辐射噪声的用户具体占比可以根据产品对性能的要求进行调整。当然也可以是根据某个特定人的感知程度确定(例如一个听力感知灵敏度高的人)。In order to improve the versatility of the preset transmission power, exemplarily, taking the Bluetooth device as a Bluetooth headset as an example, 100 users can be randomly selected to adjust the transmission power of the specified Bluetooth headset. When the radiation noise causes more than 60 users among the 100 users to perceive the radiation noise, the transmission power at this time is determined as the preset transmission power. The proportion can be adjusted according to the performance requirements of the product. Of course, it can also be determined according to the perception level of a specific person (for example, a person with high hearing perception sensitivity).
一些实施例中,由于使得辐射噪声满足第一条件的预设发射功率可能有多个,例如在一个范围内,但有的发射功率过低可能不利于蓝牙连接,因此还需要考虑蓝牙连接的性能,其中,蓝牙连接性能可以通过特定距离下的蓝牙连接速度等方式来衡量。例如,蓝牙连接的性能可以包括在特定的距离内,能够满足连接的要求,例如,在特定距离内,满足蓝牙连接速度要求,或者,满足蓝牙连接时长要求等,因此,蓝牙设备可以根据其发送蓝牙连接信号产生的辐射噪声和预设蓝牙连接性能确定上述预设发射功率;预设蓝牙连接性能可以根据产品需求、用户体验等来确定。例如,确定预设发射功率包括:调整指定蓝牙设备的当前蓝牙发射功率,当以当前蓝牙发射功率发射该蓝牙信号(在建立蓝牙连接的部分或全部过程中的蓝牙信号)满足预设蓝牙连接性能且产生的辐射噪声满足第一条件时,以当前的蓝牙发射功率作为预设发射功率,示例的,确定该预设发射功率,在建立蓝牙连接的部分或全部过程中,以该预设发射功率产生的辐射噪声不被用户感知,或者被用户感知的程度很弱,并且,该预设发射功率有利于建立蓝牙连接。In some embodiments, there may be multiple preset transmit powers that make the radiated noise meet the first condition, for example, within a range, but some transmit powers are too low, which may be unfavorable for the Bluetooth connection, so the performance of the Bluetooth connection also needs to be considered. , in which the Bluetooth connection performance can be measured by the Bluetooth connection speed at a specific distance and so on. For example, the performance of the Bluetooth connection can be included within a specific distance, which can meet the connection requirements, for example, within a specific distance, meet the Bluetooth connection speed requirements, or meet the Bluetooth connection duration requirements, etc. Therefore, the Bluetooth device can send according to its The above-mentioned preset transmit power is determined by the radiation noise generated by the Bluetooth connection signal and the preset Bluetooth connection performance; the preset Bluetooth connection performance can be determined according to product requirements, user experience, and the like. For example, determining the preset transmission power includes: adjusting the current Bluetooth transmission power of the specified Bluetooth device, and when transmitting the Bluetooth signal (the Bluetooth signal in part or all of the process of establishing the Bluetooth connection) at the current Bluetooth transmission power, the preset Bluetooth connection performance is satisfied. And when the generated radiation noise satisfies the first condition, the current Bluetooth transmission power is used as the preset transmission power. For example, the preset transmission power is determined, and the preset transmission power is used in part or all of the process of establishing the Bluetooth connection. The generated radiation noise is not perceived by the user, or is very weakly perceived by the user, and the preset transmit power is favorable for establishing a Bluetooth connection.
也就是说,预设发射功率可以根据指定蓝牙设备在建立蓝牙连接的部分或全部过程中产生的辐射噪声和预设的蓝牙连接性能确定。进一步的,预设发射功率根据指定蓝牙设备在建立蓝牙连接的部分或全部过程中发射的蓝牙信号满足预设的蓝牙连接性能且产生的辐射噪声满足上述任一第一条件时,该指定蓝牙设备对应的发射功率确定。上述蓝牙连接方法中,在建立蓝牙连接的部分或全部过程中,由于蓝牙设备是根据预设发射功率发射的蓝牙信号,使得发送的蓝牙信号产生的辐射噪声能够满足第一条件,由于预设发射功率可以使得发送的蓝牙信号产生的辐射噪声能够满足第一条件,也即发送的蓝牙信号产生的辐射噪声不被用户感知或者被用户感知的程度很弱(弱于特定的阈值,该特定的阈值可以根据需要设置,也可能受个体感知差异影响),因此,该预设发射功率需能够使得蓝牙设备在发射蓝牙信号时消耗的功率较小,从而使蓝牙设备产生的电流波动较弱,进而减少电磁辐射对喇叭、麦克风等敏感器件产生的干扰。That is to say, the preset transmit power may be determined according to the radiation noise generated by the specified Bluetooth device during part or all of the process of establishing the Bluetooth connection and the preset Bluetooth connection performance. Further, when the preset transmission power satisfies the preset Bluetooth connection performance according to the Bluetooth signal transmitted by the designated Bluetooth device during part or all of the process of establishing the Bluetooth connection, and the generated radiation noise satisfies any one of the above-mentioned first conditions, the designated Bluetooth device The corresponding transmit power is determined. In the above Bluetooth connection method, in part or all of the process of establishing the Bluetooth connection, since the Bluetooth device transmits the Bluetooth signal according to the preset transmission power, the radiation noise generated by the transmitted Bluetooth signal can satisfy the first condition, and the preset transmission The power can make the radiation noise generated by the transmitted Bluetooth signal meet the first condition, that is, the radiation noise generated by the transmitted Bluetooth signal is not perceived by the user or is very weakly perceived by the user (weaker than a specific threshold, the specific threshold It can be set according to needs, and may also be affected by individual perception differences), therefore, the preset transmission power needs to be able to make the Bluetooth device consume less power when transmitting Bluetooth signals, so that the current fluctuation generated by the Bluetooth device is weaker, thereby reducing Interference caused by electromagnetic radiation to sensitive devices such as speakers and microphones.
本实施例中,蓝牙设备在根据预设发射功率发射蓝牙信号之前先确定该预设发射功率,能够确保蓝牙设备以该发射功率发射蓝牙信号,使发送蓝牙信号产生的辐射噪声满足第一条件,保证了蓝牙设备在发射蓝牙信号时消耗的功率较小,从而使蓝牙设备产生的电流波动较弱,进而减少了电磁辐射对喇叭、麦克风等敏感器件产生的干扰。In this embodiment, the Bluetooth device determines the preset transmission power before transmitting the Bluetooth signal according to the preset transmission power, which can ensure that the Bluetooth device transmits the Bluetooth signal with the transmission power, so that the radiation noise generated by the transmission of the Bluetooth signal satisfies the first condition, This ensures that the bluetooth device consumes less power when transmitting bluetooth signals, so that the current fluctuation generated by the bluetooth device is weaker, thereby reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones.

在一个实施例中,如图4所示,提供了一种耳机,包括:处理器、分别与处理器连接的收发器、扬声器和电池;In one embodiment, as shown in FIG. 4, an earphone is provided, comprising: a processor, a transceiver connected to the processor, a speaker, and a battery;
处理器用于在建立蓝牙连接的部分或全部过程中,控制收发器根据预设发射功率发射蓝牙信号,使得收发器发射蓝牙信号产生的辐射噪声满足第一条件。The processor is configured to control the transceiver to transmit the Bluetooth signal according to the preset transmission power during part or all of the process of establishing the Bluetooth connection, so that the radiation noise generated by the transceiver transmitting the Bluetooth signal satisfies the first condition.
在本实施例中,耳机的处理器用于在建立蓝牙连接的部分或全部过程中,控制收发器根据预设发射功率发射蓝牙信号,使得收发器发射蓝牙信号产生的辐射噪声满足第一条件。其中,建立蓝牙连接的过程包括不同的阶段(例如可以包括查询、查询扫描、寻呼、寻呼扫描等状态),在蓝牙首次连接、蓝牙配对和蓝牙回连等场景中,蓝牙连接包括的步骤可能不同。该实施例,可以应用在建立蓝牙连接的部分或全部过程中,例如,在蓝牙寻呼page过程中;和/或,在蓝牙查询inquiry过程中,进一步的,可以是在蓝牙连接非正常中断后重新建立蓝牙连接的部分或全部过程中;这种情况下,可能是蓝牙受到干扰(如身体遮挡等),也可以是受到距离干扰(如离音源设备距离较远),还可以是其他非正常的原因导致在使用过程中发生蓝牙连接中断,此时耳机会重新进行蓝牙连接,例如进入寻呼状态,基于跳频协议发射ID包(即在蓝牙连接非正常中断后重新建立蓝牙连接的蓝牙寻呼page过程中),由于会在某些频段持续一定时间发送蓝牙信号(例如ID包)并且快速切换频段发射等因素会导致电流波动等问题,从而产生底噪(辐射噪声),此时,处理器控制收发器根据预设发射功率发射蓝牙信号,从而通过控制蓝牙发射功率来控制发送蓝牙信号产生的辐射噪声,使其满足第一条件,进而控制底噪对用户的影响。当然,在有些情况下,耳机在连接过程中还需要处于查询状态,查询状态下也需要在各种频带发射蓝牙信号,因此可能产生辐射噪声,为了降低噪声,也可以控制收发器采用调整至预设发射功率的方式 来发射蓝牙信号。为了方便控制,也可以在建立蓝牙连接的整个过程中处理器控制收发器均采用预设发射功率来发射蓝牙信号。In this embodiment, the processor of the headset is configured to control the transceiver to transmit the Bluetooth signal according to the preset transmit power during part or all of the process of establishing the Bluetooth connection, so that the radiated noise generated by the transceiver transmitting the Bluetooth signal satisfies the first condition. Among them, the process of establishing a Bluetooth connection includes different stages (for example, it may include states such as query, query scan, paging, and page scan). May be different. This embodiment can be applied in part or all of the process of establishing a Bluetooth connection, for example, in the process of Bluetooth paging; and/or in the process of Bluetooth inquiry, further, after the Bluetooth connection is abnormally interrupted Part or all of the process of re-establishing the Bluetooth connection; in this case, the Bluetooth may be interfered (such as body block, etc.), or it may be interfered by distance (such as being far away from the audio source device), or other abnormal The reason causes the bluetooth connection to be interrupted during use. At this time, the headset will reconnect to the bluetooth, for example, enter the paging state, and transmit the ID packet based on the frequency hopping protocol (that is, the bluetooth search for re-establishing the bluetooth connection after the bluetooth connection is abnormally interrupted). During the page call process), due to the fact that Bluetooth signals (such as ID packets) will be sent in certain frequency bands for a certain period of time, and factors such as fast switching frequency band transmission will cause problems such as current fluctuations, resulting in noise floor (radiation noise). The transceiver controls the transceiver to transmit the Bluetooth signal according to the preset transmission power, so as to control the radiation noise generated by the transmission of the Bluetooth signal by controlling the Bluetooth transmission power, so that the first condition is satisfied, and then the influence of the noise floor on the user is controlled. Of course, in some cases, the headset needs to be in the query state during the connection process, and the Bluetooth signal needs to be transmitted in various frequency bands in the query state, so radiation noise may be generated. In order to reduce noise, the transceiver can also be controlled to adjust to the preset Set the transmission power to transmit Bluetooth signals. In order to facilitate control, the processor may also control the transceiver to use a preset transmit power to transmit the Bluetooth signal during the entire process of establishing the Bluetooth connection.
可以理解的,预设发射功率与耳机在建立蓝牙连接后的蓝牙发射功率不同。也就是说在上述建立蓝牙连接的部分或全部过程中,处理器可以将蓝牙发送功率调整到预设发射功率,该预设发射功率与蓝牙连接状态下发送蓝牙数据时的发射功率可以不相同,从而能够实现特定场景下控制蓝牙辐射噪声的作用。一般来说,预设发射功率可以小于蓝牙设备在建立蓝牙连接后的蓝牙发射功率,从而降低在连接过程(特别是蓝牙寻呼或查询过程中)中产生的蓝牙辐射噪声。It can be understood that the preset transmission power is different from the Bluetooth transmission power of the headset after the Bluetooth connection is established. That is to say, during part or all of the above process of establishing a Bluetooth connection, the processor may adjust the Bluetooth transmission power to a preset transmission power, which may be different from the transmission power when the Bluetooth data is sent in the Bluetooth connection state. Thus, the function of controlling Bluetooth radiation noise in a specific scenario can be realized. Generally speaking, the preset transmit power may be lower than the Bluetooth transmit power of the Bluetooth device after the Bluetooth connection is established, thereby reducing the Bluetooth radiation noise generated during the connection process (especially during the Bluetooth paging or inquiry process).
在本实施例中,耳机的处理器在建立蓝牙连接的部分或全部过程中,处理器控制耳机的收发器根据预设发射功率发射蓝牙信号,使得收发器发送该蓝牙信号产生的辐射噪声满足第一条件。其中,第一条件可以表征为耳机在发射蓝牙信号时产生的辐射噪声很弱,人耳基本感觉不到该辐射噪声,或者,第一条件可以为耳机在发射蓝牙信号时产生的辐射噪声可以被用户感知到,但感知的程度很弱(例如弱于特定的阈值,该特定的阈值可以根据需要设置,也可能受个体感知差异影响)。或者,该第一条件还可以包括一些辐射噪声的参数,用噪声参数来衡量产生的辐射噪声的情况,例如,该参数可以包括辐射噪声的强度(单位“分贝”)阈值,则在建立蓝牙连接的部分或全部过程中,发射蓝牙信号时产生的辐射噪声的强度控制在小于该强度阈值的范围内时,可以使得发射蓝牙信号时产生的辐射噪声不足以被用户感知,或者,使得发射蓝牙信号时产生的辐射噪声被用户感知到一些,但用户感知到的辐射噪声很弱,不会影响蓝牙设备的使用性能。In this embodiment, during part or all of the process of establishing a Bluetooth connection, the processor of the headset controls the transceiver of the headset to transmit the Bluetooth signal according to the preset transmission power, so that the radiated noise generated by the transceiver sending the Bluetooth signal satisfies the requirements of the first a condition. The first condition may be characterized by the fact that the radiated noise generated by the earphone when transmitting the Bluetooth signal is very weak, and the radiated noise is basically not felt by the human ear, or the first condition may be that the radiated noise generated by the earphone when transmitting the Bluetooth signal can be The user perceives, but the degree of perception is weak (for example, weaker than a specific threshold, which can be set as needed, and may also be affected by individual differences in perception). Alternatively, the first condition may also include some parameters of radiated noise, and the noise parameter may be used to measure the situation of the generated radiated noise. For example, the parameter may include a threshold of the intensity of radiated noise (unit "dB"), then when the Bluetooth connection is established In part or all of the process, when the intensity of the radiation noise generated when the Bluetooth signal is transmitted is controlled within a range less than the intensity threshold, the radiation noise generated when the Bluetooth signal is transmitted can not be perceived by the user, or the Bluetooth signal is transmitted. The radiated noise generated by the user is perceived by the user, but the radiated noise perceived by the user is very weak and will not affect the performance of the Bluetooth device.
需要说明的是,耳机在不同的使用场景中,对应的上述第一条件也可以是不同的,在嘈杂的环境中使用耳机时,第一条件对于辐射噪声的要求可以相对较低;在安静环境中使用耳机时,第一条件对于辐射噪声的要求可以相对较高;又例如,老年人使用耳机时,第一条件对于辐射噪声的要求可以相对较低,也就是说可以控制预设发射功率相对高一些,虽然产生的辐射噪声会大一些,但是由于环境嘈杂,用户不易感知;成年人使用耳机时,第一条件对于辐射噪声的要求可以相对较高,也就是说安静环境下需要控制预设发射功率相对低一些,从而不产生辐射噪声或者产生的辐射噪声不被用户感知;又例如,老年人使用蓝牙耳机时,第一条件对于辐射噪声的要求可以相对较低,老年人对声音感知较弱,因此允许提升发射功率,即使产生的辐射噪声稍大也不影响使用;而对于青年或成年人使用蓝牙耳机时,第一条件对于辐射噪声的要求可以相对较高,避免过大噪声影响用户体验。本申请实施例中不加以限制。It should be noted that in different usage scenarios of headphones, the corresponding first conditions may also be different. When headphones are used in a noisy environment, the requirements for radiation noise of the first condition may be relatively low; in a quiet environment When using earphones in China, the requirements for radiation noise in the first condition may be relatively high; for another example, when the elderly use earphones, the requirements for radiation noise in the first condition may be relatively low, that is to say, the preset transmit power can be controlled to be relatively Higher, although the radiated noise will be larger, but due to the noisy environment, the user is not easy to perceive; when adults use headphones, the first condition for radiated noise can be relatively high, that is, in a quiet environment, it is necessary to control the preset The transmission power is relatively low, so that no radiated noise is generated or the generated radiated noise is not perceived by the user; for another example, when the elderly use a Bluetooth headset, the first condition may have relatively low requirements for radiated noise, and the elderly are more sensitive to sound. Weak, so it is allowed to increase the transmission power, even if the radiated noise generated is slightly larger, it will not affect the use; while for young people or adults to use Bluetooth headsets, the first condition for radiated noise can be relatively high, so as to avoid excessive noise affecting users experience. No limitation is imposed in the embodiments of the present application.
上述耳机,在建立蓝牙连接的部分或全部过程中,由于耳机是根据预设发射功率发射的蓝牙信号,使得发送的蓝牙信号产生的辐射噪声能够满足第一条件,由于预设发射功率可以使得发送的蓝牙信号产生的辐射噪声能够满足第一条件,也即发送的蓝牙信号产生的辐射噪声不足以被用户感知或者被用户感知的程度很弱(弱于特定的阈值,该特定的阈值可以根据需要设置,也可能受个体感知差异影响),因此,该预设发射功率需能够使得耳机在发射蓝牙信号时消耗的功率较小,从而使耳机产生的电流波动较弱,进而减少电磁辐射对喇叭、麦克风等敏感器件产生的干扰。In the above-mentioned earphone, during part or all of the process of establishing the Bluetooth connection, since the earphone transmits the Bluetooth signal according to the preset transmission power, the radiation noise generated by the transmitted Bluetooth signal can meet the first condition, and the preset transmission power can make the transmission The radiation noise generated by the Bluetooth signal can meet the first condition, that is, the radiation noise generated by the transmitted Bluetooth signal is not enough to be perceived by the user or is very weak by the user (weaker than a specific threshold, the specific threshold can be based on needs. settings, may also be affected by individual perception differences), therefore, the preset transmission power needs to be able to make the headset consume less power when transmitting Bluetooth signals, so that the current generated by the headset fluctuates weakly, thereby reducing electromagnetic radiation. Interference from sensitive devices such as microphones.
在上述耳机的处理器用于在建立蓝牙连接的部分或全部过程中,控制耳机的收发器根据预设发射功率发射蓝牙信号,使得发射的蓝牙信号产生的辐射噪声满足第一条件的场景中,在一个实施例中,第一条件表征辐射噪声被用户感知的程度。In the scenario where the processor of the above-mentioned earphone is used to control the transceiver of the earphone to transmit the Bluetooth signal according to the preset transmission power during part or all of the process of establishing the Bluetooth connection, so that the radiation noise generated by the transmitted Bluetooth signal satisfies the first condition, in the scenario of In one embodiment, the first condition characterizes the degree to which the radiated noise is perceived by the user.
在本实施例中,上述第一条件表征耳机发送蓝牙信号产生的辐射噪声被用户感知的程度。可选的,该第一条件可以表征耳机发送蓝牙信号产生的辐射噪声的强度被用户感知的程度。其中,被用户感知的程度可以包括不被用户感知或者被用户感知的程度很弱(弱于特定的阈值,该特定的阈值可以根据需要设置,也可能受个体感知差异影响),例如,通常情况下,1分贝是人类耳朵刚刚能听到的声音,20分贝以下的声音,一般来说,可以认为它是安静的,那么,1分贝以下的辐射噪声是不足以被用户感知的,1分贝到20分贝之间的声音可以认为被用户感知的程度很弱,本申请实施例中并不以次为限。可以理解的是,由于个体间的差异,辐射噪声被用户感知的程度也会有所不同。示例性地,可以预先选择 不同年龄段的用户在不同环境中,测试各个年龄段的用户在各种环境中对于辐射噪声的感知程度,或者,可以采用模拟人耳的设备,在不同的环境中对这些模拟人耳感知的辐射噪声的程度,从而确定在各种场景中耳机发射蓝牙信号时产生的辐射噪声被用户感知的程度。可以理解的,由于每个用户感知程度可能不同,因此第一条件的用户感知程度,也可以表示为将辐射噪声控制在大部分用户不能感知的条件下即可,例如100名随机用户中,超过50名感知不到,具体占比可以根据产品对性能的要求进行调整。In this embodiment, the above-mentioned first condition represents the degree to which the radiated noise generated by the Bluetooth signal sent by the earphone is perceived by the user. Optionally, the first condition may represent the degree to which the intensity of the radiation noise generated by the Bluetooth signal sent by the headset is perceived by the user. The degree of being perceived by the user may include not being perceived by the user or being very weakly perceived by the user (less than a specific threshold, the specific threshold can be set as required, and may also be affected by individual perception differences), for example, the usual situation Below, 1 decibel is the sound that human ears can just hear. Generally speaking, the sound below 20 decibels can be considered to be quiet. Then, the radiated noise below 1 decibel is not enough to be perceived by the user. The sound between 20 decibels can be considered to be very weak to be perceived by the user, which is not limited to times in the embodiments of the present application. It is understandable that, due to individual differences, the degree to which radiated noise is perceived by users will also vary. Exemplarily, users of different age groups may be preselected in different environments to test the perception level of users of different age groups to radiated noise in various environments, or a device that simulates human ears may be used in different environments. The degree of radiated noise perceived by the human ear is simulated, so as to determine the degree to which the radiated noise generated when the headset transmits a Bluetooth signal is perceived by the user in various scenarios. It is understandable that since each user's perception level may be different, the user's perception level of the first condition can also be expressed as controlling the radiated noise under conditions that most users cannot perceive. For example, among 100 random users, more than 50 people cannot perceive it, and the specific proportion can be adjusted according to the performance requirements of the product.
本实施例中,由于第一条件表征耳机发送蓝牙信号产生的辐射噪声被用户感知的程度,而耳机发射蓝牙信号产生的辐射噪声是满足该第一条件的,也就是说耳机在发射蓝牙信号时产生的辐射噪声在用户感知的可接受范围内,即在这种情况下耳机在发射蓝牙信号时消耗的功率较小,从而使耳机产生的电流波动较弱,进而减少了电磁辐射对喇叭、麦克风等敏感器件产生的干扰影响,即减少了耳机发送蓝牙连接请求信号时对喇叭、麦克风等敏感器件产生的干扰。In this embodiment, since the first condition represents the degree to which the radiated noise generated by the Bluetooth signal transmitted by the headset is perceived by the user, the radiation noise generated by the Bluetooth signal transmitted by the headset satisfies the first condition, that is to say, when the headset transmits the Bluetooth signal The generated radiated noise is within the acceptable range of user perception, that is, in this case, the earphone consumes less power when transmitting Bluetooth signals, so that the current fluctuation generated by the earphone is weaker, which in turn reduces the impact of electromagnetic radiation on speakers and microphones. It reduces the interference caused by sensitive devices such as the headset, that is, reduces the interference to sensitive devices such as speakers and microphones when the headset sends a Bluetooth connection request signal.
在上述耳机的处理器用于在建立蓝牙连接的部分或全部过程中,控制耳机的收发器根据预设发射功率发射蓝牙信号的场景中,在另一个实施例中,收发器发射蓝牙信号产生的辐射噪声的强度与耳机的发射功率和耳机的设备参数有相关性。In a scenario where the processor of the headset is used to control the transceiver of the headset to transmit a Bluetooth signal according to a preset transmission power during part or all of the process of establishing a Bluetooth connection, in another embodiment, the transceiver transmits radiation generated by the Bluetooth signal. The intensity of the noise is related to the transmit power of the earphone and the device parameters of the earphone.
在本实施例中,耳机的收发器发射蓝牙信号产生的辐射噪声的强度与耳机的发射功率和耳机的设备参数有相关性。可选的,耳机的设备参数包括耳机的扬声器的灵敏度、扬声器与电池之间的距离、天线的效率中的至少一个。可选的,耳机的收发器发射蓝牙信号产生的辐射噪声的强度与耳机的发射功率和耳机的设备参数的相关性包括以下至少一种:耳机的扬声器的灵敏度与辐射噪声的强度正相关;耳机的扬声器与电池之间的距离与辐射噪声的强度负相关;耳机的天线的效率与辐射噪声的强度正相关;耳机的发射功率与辐射噪声的强度正相关。可以理解的是,耳机的扬声器的灵敏度与辐射噪声的强度正相关,即耳机的扬声器的灵敏度越高,辐射噪声的强度越大,耳机的扬声器的灵敏度越低,辐射噪声的强度越弱;耳机的扬声器与电池之间的距离与辐射噪声的强度负相关,即耳机的扬声器与电池之间的距离越远,辐射噪声的强度越弱,耳机的扬声器与电池之间的距离越近,辐射噪声的强度越强;耳机的天线的效率与辐射噪声的强度正相关,即耳机的天线的效率越高,辐射噪声的强度越强,耳机的天线的效率越低,辐射噪声的强度越弱;耳机的发射功率与辐射噪声的强度正相关,即耳机的发射功率越大,辐射噪声的强度越大,耳机的发射功率越小,辐射噪声的强度越小。In this embodiment, the intensity of the radiated noise generated by the transceiver of the earphone transmitting the Bluetooth signal is related to the transmit power of the earphone and the device parameters of the earphone. Optionally, the device parameter of the earphone includes at least one of the sensitivity of the speaker of the earphone, 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 headset transmitting the Bluetooth signal and the transmission power of the headset and the device parameters of the headset includes at least one of the following: the sensitivity of the speaker of the headset is positively correlated with the intensity of the radiated noise; The distance between the speaker and the battery is negatively related to the intensity of the radiated noise; the efficiency of the antenna of the headset is positively related to the intensity of the radiated noise; the emission power of the headset is positively related to the intensity of the radiated noise. It can be understood that the sensitivity of the speaker of the earphone is positively related to the intensity of the radiated noise, that is, the higher the sensitivity of the speaker of the earphone, the greater the intensity of the radiated noise, the lower the sensitivity of the speaker of the earphone, the weaker the intensity of the radiated noise; The distance between the speaker and the battery is negatively related to the intensity of the radiated noise, that is, the farther the distance between the speaker of the headset and the battery, the weaker the intensity of the radiated noise, and the closer the distance between the speaker of the headset and the battery, the less the radiated noise. The intensity of the earphone is stronger; the efficiency of the earphone antenna is positively related to the intensity of the radiation noise, that is, the higher the efficiency of the earphone antenna, the stronger the intensity of the radiation noise, the lower the efficiency of the earphone antenna, the weaker the intensity of the radiation noise; The transmit power of the earphone is positively correlated with the intensity of the radiation noise, that is, the greater the transmit power of the earphone, the greater the intensity of the radiation noise, and the smaller the transmit power of the earphone, the smaller the intensity of the radiation noise.
本申请实施例提供的耳机,其实现原理可参照上述蓝牙连接方法的实施例,此处不再赘述。For the implementation principle of the earphone provided by the embodiment of the present application, reference may be made to the above-mentioned embodiment of the Bluetooth connection method, which will not be repeated here.
本实施例中,耳机的收发器发射蓝牙信号产生的辐射噪声的强度与耳机的发射功率和耳机的设备参数有相关性,因此,具有不同设备参数的蓝牙耳机,其在蓝牙连接过程中产生的辐射噪声可能不同,由于受设备结构设计的影响,这些设备参数往往不好调整,特别是蓝牙耳机这种体型小的设备,设备参数调整空间有限,从而采用调整蓝牙发射功率的方式来控制在建立蓝牙连接的部分或全部过程中的噪声辐射,从其他角度解决底噪问题,提升蓝牙设备的产品性能。In this embodiment, the intensity of the radiated noise generated by the transceiver of the earphone transmitting the Bluetooth signal is related to the transmit power of the earphone and the device parameters of the earphone. The radiated noise may be different. Due to the influence of the device structure design, these device parameters are often difficult to adjust, especially for small devices such as Bluetooth headsets. Noise radiation in part or all of the Bluetooth connection process can solve the noise floor problem from other perspectives and improve the product performance of Bluetooth devices.

在本实施例中,蓝牙耳机的处理器被配置用于控制蓝牙收发器的发射功率调整至预设发射功率,蓝牙收发器被配置用于以预设发射功率在蓝牙寻呼page过程中发射蓝牙信号,以使得扬声器产生的辐射噪声满足第一条件。进一步的,可以是在蓝牙连接非正常中断后重新建立蓝牙连接的蓝牙寻呼page过程中;这种情况下,可能是蓝牙受到干扰(如身体遮挡等),也可以是受到距离干扰(如离音源设备距离较远),还可以是其他非正常的原因导致在使用过程中发生蓝牙连接中断,此时蓝牙耳机会重新进入寻呼状态,基于跳频协议发 射ID包,由于会在某些频段持续一定时间发送蓝牙信号(例如ID包)并且快速切换频段发射等因素会导致电流波动等问题,,从而产生底噪(辐射噪声),此时,蓝牙耳机根据预设发射功率发射蓝牙信号,从而通过控制蓝牙发射功率来控制发送蓝牙信号产生的辐射噪声,使其满足第一条件,进而控制底噪对用户的影响。可以理解的,预设发射功率与蓝牙耳机在建立蓝牙连接后的蓝牙发射功率不同。也就是说在上述蓝牙寻呼page过程中,可以将蓝牙发送功率调整到预设发射功率,该预设发射功率与蓝牙连接状态下发送蓝牙数据时的发射功率可以不相同,从而能够实现特定场景下控制蓝牙辐射噪声的作用。一般来说,预设发射功率可以小于蓝牙耳机在建立蓝牙连接后的蓝牙发射功率,从而降低在连接过程(特别是蓝牙寻呼或查询过程中)中产生的蓝牙辐射噪声。In this embodiment, the processor of the Bluetooth headset is configured to control the transmission power of the Bluetooth transceiver to be adjusted to a preset transmission power, and the Bluetooth transceiver is configured to transmit the Bluetooth with the preset transmission power during the Bluetooth paging page process signal, so that the radiated noise generated by the speaker satisfies the first condition. Further, it may be in the process of re-establishing the Bluetooth paging page of the Bluetooth connection after the Bluetooth connection is abnormally interrupted; in this case, the Bluetooth may be interfered (such as body block, etc.) The audio source device is far away), or other abnormal reasons may cause the Bluetooth connection to be interrupted during use. At this time, the Bluetooth headset will re-enter the paging state and transmit ID packets based on the frequency hopping protocol. Sending Bluetooth signals (such as ID packets) for a certain period of time and quickly switching frequency bands for transmission will cause problems such as current fluctuations, resulting in noise floor (radiation noise). At this time, the Bluetooth headset transmits Bluetooth signals according to the preset transmission power, thereby The radiation noise generated by sending the Bluetooth signal is controlled by controlling the Bluetooth transmission power, so that the first condition is satisfied, and the influence of the noise floor on the user is further controlled. It can be understood that the preset transmission power is different from the Bluetooth transmission power of the Bluetooth headset after the Bluetooth connection is established. That is to say, in the process of the above-mentioned Bluetooth paging page, the Bluetooth transmission power can be adjusted to the preset transmission power, and the preset transmission power can be different from the transmission power when the Bluetooth data is sent in the Bluetooth connection state, so that specific scenarios can be realized. Control the effect of Bluetooth radiated noise. Generally speaking, the preset transmit power may be smaller than the Bluetooth transmit power of the Bluetooth headset after the Bluetooth connection is established, thereby reducing the Bluetooth radiation noise generated during the connection process (especially during the Bluetooth paging or inquiry process).
在本实施例中,蓝牙耳机的处理器被配置用于控制蓝牙收发器的发射功率调整至预设发射功率,蓝牙收发器被配置用于以该预设发射功率在蓝牙寻呼page过程中发射蓝牙信号,以使得蓝牙耳机的扬声器产生的辐射噪声满足第一条件。其中,第一条件可以表征为蓝牙耳机在发射蓝牙信号时产生的辐射噪声很弱,人耳基本感觉不到该辐射噪声,或者,第一条件可以为蓝牙耳机在发射蓝牙信号时产生的辐射噪声可以被用户感知到,但感知的程度很弱。或者,该第一条件还可以包括一些辐射噪声的参数,用噪声参数来衡量产生的辐射噪声的情况,例如,该参数可以包括辐射噪声的强度阈值,则在发射蓝牙信号时产生的辐射噪声的强度控制在小于该强度阈值的范围内时,可以使得发射蓝牙信号时产生的辐射噪声不足以被用户感知,或者,使得发射蓝牙信号时产生的辐射噪声被用户感知到,但用户感知到的辐射噪声很弱,不会影响蓝牙耳机的使用性能。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, and the Bluetooth transceiver is configured to transmit at the preset transmission power during the Bluetooth paging page process Bluetooth signal, so that the radiated noise generated by the speaker of the Bluetooth headset satisfies the first condition. The first condition may be characterized by the fact that the radiation noise generated by the Bluetooth headset when transmitting the Bluetooth signal is very weak, and the radiated noise is basically not felt by the human ear, or the first condition may be the radiation noise generated by the Bluetooth headset when transmitting the Bluetooth signal. Can be perceived by the user, but to a very weak degree. Alternatively, the first condition may also include some parameters of radiated noise, and the noise parameters may be used to measure the generated radiated noise. For example, the parameter may include the intensity threshold of radiated noise, and the When the intensity is controlled within a range less than the intensity threshold, the radiation noise generated when the Bluetooth signal is transmitted can be insufficient to be perceived by the user, or the radiation noise generated when the Bluetooth signal is transmitted can be perceived by the user, but the radiation perceived by the user is not enough. The noise is very weak and will not affect the performance of the Bluetooth headset.
需要说明的是,蓝牙耳机在不同的使用场景中,对应的上述第一条件也可以是不同的,在嘈杂的环境中使用耳机时,第一条件对于辐射噪声的控制要求可以相对较低;在安静环境中使用耳机时,第一条件对于辐射噪声的控制要求可以相对较高;又例如,老年人使用耳机时,第一条件对于辐射噪声的控制要求可以相对较低,成年人使用耳机时,第一条件对于辐射噪声的控制要求可以相对较高。本申请实施例中不加以限制。It should be noted that in different usage scenarios of the Bluetooth headset, the corresponding first condition may also be different.

上述蓝牙耳机,处理器被配置用于控制蓝牙收发器的发射功率调整至预设发射功率,蓝牙收发器被配置用于以预设发射功率在蓝牙寻呼page过程中发射蓝牙信号,以使得扬声器产生的辐射噪声满足第一条件,由于蓝牙耳机是以调整的预设发射功率发射的蓝牙信号,使得发送的蓝牙信号产生的辐射噪声能够满足第一条件,由于预设发射功率可以使得发送的蓝牙信号产生的辐射噪声能够满足第一条件,也即发送的蓝牙信号产生的辐射噪声不足以被用户感知或者被用户感知的程度很弱(弱于特定的阈值),因此,该预设发射功率需能够使得蓝牙耳机在发射蓝牙信号时消耗的功率较小,从而使蓝牙耳机产生的电流波动较弱,进而减少电磁辐射对喇叭、麦克风等敏感器件产生的干扰。For the above-mentioned Bluetooth headset, the processor is configured to control the transmission power of the Bluetooth transceiver to be adjusted to a preset transmission power, and the Bluetooth transceiver is configured to transmit a Bluetooth signal with the preset transmission power during the Bluetooth paging page process, so that the speaker The generated radiation noise satisfies the first condition, because the Bluetooth headset transmits the Bluetooth signal with the adjusted preset transmission power, so that the radiation noise generated by the transmitted Bluetooth signal can meet the first condition, because the preset transmission power can make the transmitted Bluetooth The radiation noise generated by the signal can satisfy the first condition, that is, the radiation noise generated by the transmitted Bluetooth signal is not enough to be perceived by the user or is very weak (less than a specific threshold), so the preset transmit power needs to be The power consumption of the bluetooth headset when transmitting the bluetooth signal is small, so that the current fluctuation generated by the bluetooth headset is weaker, thereby reducing the interference of electromagnetic radiation on sensitive devices such as speakers and microphones.
在上述蓝牙耳机的处理器被配置用于控制蓝牙收发器的发射功率调整至预设发射功率的场景中,需要说明的是,预设发射功率可以是通过该蓝牙设备确定的,也可以是通过指定蓝牙设备确定的,该指定蓝牙设备可以是上述蓝牙设备,也可以是与上述蓝牙设备具有相同性能的蓝牙设备,例如工程样机、试量产样机等,通过测试确定出预设发射功率后,在量产时设置在上述蓝牙设备中。当然也可以在蓝牙设备出厂后根据用户需要确定,原理是相同的,本申请对此不做限制。在本实施例中,蓝牙收发器被配置用于以预设发射功率在蓝牙寻呼page过程中发射蓝牙信号之前,需要先确定该预设发射功率,使得蓝牙耳机的扬声器发射蓝牙信号产生的辐射噪声满足上述第一条件。可选的,该预设发射功率可以是在蓝牙耳机出厂前进行测试得到,可以是人工或者机器测试确定,例如指定蓝牙耳机可以通过调整其当前蓝牙发射功率,在蓝牙寻呼page过程中,以所述当前蓝牙发射功率发送蓝牙信号产生的辐射噪声满足第一条件时,将当前蓝牙发射功率确定为上述预设发射功率。通常,蓝牙耳机的蓝牙发射功率是0dbm~10dbm,蓝牙耳机可以通过预设的频率调整间隔,从0dbm开始调整蓝牙耳机的蓝牙发射功率,当蓝牙耳机发送蓝牙信号扬声器产生的辐射噪声满足上述第一条件时,将当前的蓝牙发射功率确定为上述预设发射功率。示例性地,以预设的频率调整间隔为2dbm为例,蓝牙耳机从10dbm开始,以2dbm的频率调整间隔调整蓝牙耳机的蓝牙发射功率,当调整蓝牙耳机的蓝牙发射功率为4dbm时,发送蓝牙信 号产生的辐射噪声满足上述第一条件,则蓝牙耳机将当前的发射功率4dbm确定为上述预设发射功率,本申请实施例并不以此为限。In the scenario where the processor of the Bluetooth headset is configured to control the transmission power of the Bluetooth transceiver to be adjusted to the preset transmission power, it should be noted that the preset transmission power may be determined by the Bluetooth device, or may be determined by the Bluetooth device. Determined by a designated Bluetooth device, the designated Bluetooth device may be the above-mentioned Bluetooth device, or it may be a Bluetooth device with the same performance as the above-mentioned Bluetooth device, such as an engineering prototype, a trial production prototype, etc. After the preset transmission power is determined through testing, Set in the above-mentioned Bluetooth device at the time of mass production. Of course, it can also be determined according to user needs after the Bluetooth device leaves the factory. The principle is the same, which is not limited in this application. In this embodiment, before the Bluetooth transceiver is configured to transmit a Bluetooth signal with a preset transmission power during the Bluetooth paging page process, the preset transmission power needs to be determined first, so that the speaker of the Bluetooth headset transmits the radiation generated by the Bluetooth signal The noise satisfies the above-mentioned first condition. Optionally, the preset transmission power can be obtained by testing the Bluetooth headset before it leaves the factory, and it can be determined by manual or machine testing. For example, a specified Bluetooth headset can adjust its current Bluetooth transmission power. During the Bluetooth paging page process, The current Bluetooth transmission power is determined as the preset transmission power when the radiation noise generated by the current Bluetooth transmission power sending the Bluetooth signal satisfies the first condition. Usually, the Bluetooth transmitting power of the Bluetooth headset is 0dbm ~ 10dbm, the Bluetooth headset can adjust the interval through the preset frequency, and adjust the Bluetooth transmitting power of the Bluetooth headset starting from 0dbm. When the Bluetooth headset sends a Bluetooth signal, the radiation noise generated by the speaker meets the above-mentioned first When conditions are met, the current Bluetooth transmit power is determined as the above preset transmit power. Exemplarily, taking the preset frequency adjustment interval of 2dbm as an example, the Bluetooth headset starts from 10dbm, adjusts the Bluetooth transmission power of the Bluetooth headset at a frequency adjustment interval of 2dbm, and when the Bluetooth transmission power of the Bluetooth headset is adjusted to 4dbm, send the Bluetooth If the radiation noise generated by the signal satisfies the above-mentioned first condition, the Bluetooth headset determines the current transmission power of 4 dbm as the above-mentioned preset transmission power, which is not limited in this embodiment of the present application.
一些实施例中,由于使得辐射噪声满足第一条件的预设发射功率可能有多个,例如在一个范围内,但有的发射功率过低可能不利于蓝牙连接,因此还需要考虑蓝牙连接的性能,其中,蓝牙连接性能可以通过特定距离下的蓝牙连接速度等方式来衡量,例如,蓝牙连接的性能可以包括在特定的距离内,蓝牙耳机进行连接时能够满足连接的要求,或者,在特定距离内,蓝牙耳机进行连接时能够满足连接速度的要求和连接时间的要求等,因此,指定蓝牙耳机可以根据其发送蓝牙连接信号产生的辐射噪声和预设的蓝牙连接性能确定上述预设发射功率,该预设蓝牙连接性能可以根据产品需求、用户体验等来确定。例如,确定预设发射功率包括:调整指定蓝牙耳机的当前蓝牙发射功率,当以当前蓝牙发射功率发射该蓝牙信号(在蓝牙寻呼page过程中的蓝牙信号)产生的辐射噪声满足第一条件和预设蓝牙连接性能时,以当前的蓝牙发射功率作为预设发射功率。其中,该预设蓝牙连接性能可以通过特定距离下的蓝牙连接速度等方式确定,例如,在特定距离内蓝牙耳机进行连接的蓝牙连接速度若满足预设的速度要求,则可以将该蓝牙连接速度确定为上述预设蓝牙连接性能。In some embodiments, there may be multiple preset transmit powers that make the radiated noise meet the first condition, for example, within a range, but some transmit powers are too low, which may be unfavorable for the Bluetooth connection, so the performance of the Bluetooth connection also needs to be considered. , where the Bluetooth connection performance can be measured by the Bluetooth connection speed at a specific distance, etc. For example, the performance of the Bluetooth connection can be included in a specific distance, and the Bluetooth headset can meet the connection requirements when connecting, or, at a specific distance Therefore, the specified Bluetooth headset can determine the above-mentioned preset transmission power according to the radiation noise generated by the Bluetooth connection signal sent by the Bluetooth headset and the preset Bluetooth connection performance. The preset Bluetooth connection performance may be determined according to product requirements, user experience, and the like. For example, determining the preset transmission power includes: adjusting the current Bluetooth transmission power of the specified Bluetooth headset, and when the current Bluetooth transmission power is used to transmit the Bluetooth signal (the Bluetooth signal in the Bluetooth paging page process), the radiation noise generated by the first condition and When the Bluetooth connection performance is preset, the current Bluetooth transmit power is used as the preset transmit power. Wherein, the preset Bluetooth connection performance can be determined by the Bluetooth connection speed at a specific distance, etc. For example, if the Bluetooth connection speed for connecting a Bluetooth headset within a specific distance meets the preset speed requirement, the Bluetooth connection speed can be determined. Determines the preset Bluetooth connectivity capabilities above.
