在一些实施例中,相对运动状态可以仅为运动大小,亦可以为矢量,亦即,相对运动状态可以为有方向的运动状态。In some embodiments, the relative motion state may be only a motion size, or may be a vector, that is, the relative motion state may be a directional motion state.
用户可以根据产品需求,选择合适方式检测第一耳机/第二耳机的运动状态,以进一步确定第一耳机与第二耳机之间的相对运动状态。The user can select a suitable manner to detect the motion state of the first earphone/second earphone according to the product requirement, to further determine the relative motion state between the first earphone and the second earphone.
举例而言,在一些实施例中,相对运动状态为相对距离/相对加速度/相对速度时,可以通过蓝牙方式/加速度传感器/重力传感器/红外传感器检测第一耳机与第二耳机之间的相对距离/相对加速度/相对速度,亦可以通过装配在第一 耳机或第二耳机的其它传感器或检测方式检测两者之间的相对距离/相对加速度/相对速度。For example, in some embodiments, when the relative motion state is a relative distance/relative acceleration/relative speed, the relative distance between the first earphone and the second earphone may be detected by a Bluetooth mode/acceleration sensor/gravity sensor/infrared sensor. / Relative acceleration / relative speed, the relative distance / relative acceleration / relative speed between the two can also be detected by other sensors or detection means fitted in the first earphone or the second earphone.
43、根据相对运动状态,控制第一耳机和/或第二耳机的当前工作模式的切换。43. Control switching of the current working mode of the first earphone and/or the second earphone according to the relative motion state.
当第一耳机与第二耳机为有线通信时,第一耳机与第二耳机之间可以配置有线控器,亦可以无需配置线控器。当配置有线控器时,线控器可用于控制第一耳机和/或第二耳机的当前工作模式切换。当未配置有线控器时,第一耳机与第二耳机之间互相通信,完成自身或者对方的当前工作模式切换,例如,第一耳机切换自身的当前工作模式,亦可以切换第二耳机的当前工作模式,同理可得,对于第二耳机亦然。When the first earphone and the second earphone are in wired communication, a wired controller may be disposed between the first earphone and the second earphone, and the wire controller may not be configured. When the cable controller is configured, the wire controller can be used to control the current mode of operation switching of the first earphone and/or the second earphone. When the cable controller is not configured, the first earphone and the second earphone communicate with each other to complete the current working mode switching of the user or the other party. For example, the first earphone switches its current working mode, and can also switch the current state of the second earphone. The working mode is similarly available, as is the second headset.
当第一耳机与第二耳机为无线通信时,第一耳机根据相对运动状态切换自身的或者第二耳机的当前工作模式,或者,第二耳机根据相对运动状态切换自身的或者第一耳机的当前工作模式。在另一些实施例中,第一耳机或第二耳机还可以接收音频源设备的控制指令,以完成自身或者对方的工作模式切换。When the first earphone and the second earphone are in wireless communication, the first earphone switches its current working mode of the second earphone according to the relative motion state, or the second earphone switches its current or the current state of the first earphone according to the relative motion state. Operating mode. In other embodiments, the first earphone or the second earphone may also receive a control instruction of the audio source device to complete the working mode switching of itself or the other party.
如前所述,相对运动状态的表现形式呈现多样化,因此,其可以根据多样化的相对运动状态控制第一耳机和/或第二耳机的当前工作模式的切换。具体的,其可以判断相对运动状态是否满足预设状态条件,若满足,控制第一耳机和/或第二耳机的当前工作模式的切换。若未满足,返回当前工作模式。As previously mentioned, the representation of the relative motion state is diversified, so that it can control the switching of the current operating mode of the first earphone and/or the second earphone according to the diverse relative motion state. Specifically, it can determine whether the relative motion state satisfies the preset state condition, and if so, control the switching of the current working mode of the first earphone and/or the second earphone. If not, return to the current working mode.
举例而言:相对运动状态为相对距离。当第一耳机与第二耳机的相对距离的距离值小于预设距离阈值时,控制第一耳机和/或第二耳机的当前工作模式切换至第一目标工作模式。当第一耳机与第二耳机的相对距离的距离值大于预设距离阈值时,控制第一耳机和/或第二耳机的当前工作模式切换至第二目标工作模式。For example: the relative motion state is the relative distance. When the distance value of the relative distance between the first earphone and the second earphone is less than the preset distance threshold, controlling the current working mode of the first earphone and/or the second earphone to switch to the first target working mode. When the distance value of the relative distance between the first earphone and the second earphone is greater than the preset distance threshold, controlling the current working mode of the first earphone and/or the second earphone to switch to the second target working mode.
举例而言:相对运动状态为相对速度。当第一耳机与第二耳机的相对速度的大小小于预设速度阈值时,控制第一耳机和/或第二耳机的当前工作模式切换至第一目标工作模式。当第一耳机与第二耳机的相对速度的大小大于预设速度阈值时,控制第一耳机和/或第二耳机的当前工作模式切换至第二目标工作模式。For example: the relative motion state is the relative speed. When the magnitude of the relative speed of the first earphone and the second earphone is less than the preset speed threshold, controlling the current working mode of the first earphone and/or the second earphone to switch to the first target working mode. When the magnitude of the relative speed of the first earphone and the second earphone is greater than the preset speed threshold, controlling the current working mode of the first earphone and/or the second earphone to switch to the second target working mode.
举例而言:相对运动状态为相对速度。当第一耳机的速度与第二耳机的速度的方向一致时,控制第一耳机和/或第二耳机的当前工作模式切换至第一目标 工作模式。当第一耳机的速度与第二耳机的速度的方向不一致时,控制第一耳机和/或第二耳机的当前工作模式切换至第二目标工作模式。For example: the relative motion state is the relative speed. When the speed of the first earphone coincides with the direction of the speed of the second earphone, the current operating mode of the first earphone and/or the second earphone is controlled to switch to the first target working mode. When the speed of the first earphone does not coincide with the direction of the speed of the second earphone, the current working mode of the first earphone and/or the second earphone is controlled to switch to the second target working mode.
一般的,相对运动状态包括各类运动大小与方向,本领域技术人员在本实施例所训导的内容,可以任何组合或未组合各类运动大小或方向,控制第一耳机和/或第二耳机的当前工作模式的切换。应当理解,本领域技术人员所作的变化应当落入本申请的保护范围之内。Generally, the relative motion state includes various types of motions and directions, and the content of the training in this embodiment can be controlled by the first earphone and/or the second earphone in any combination or combination of various motion sizes or directions. The switching of the current working mode. It should be understood that variations made by those skilled in the art should fall within the scope of the present application.
将当前工作模式切换至目标工作模式的过程中,当前工作模式与目标工作模式可以属于同一平行领域的工作模式,例如:音量调高模式与音量降低模式、耳机连接模式与耳机断开模式等等。在一些实施例中,当前工作模式与目标工作模式可以不属于同一平行领域的工作模式,例如:音量调高模式与耳机连接模式,音量降低模式与耳机断开模式等等。因此,在切换过程中,当前工作模式可以被切换至属于同一平行领域的工作模式,亦可以被切换至不属于同一平行领域的工作模式。本领域技术人员可以根据产品需求,自行定义工作模式之间切换的对应关系。During the process of switching the current working mode to the target working mode, the current working mode and the target working mode may belong to the same parallel domain working mode, for example, the volume up mode and the volume down mode, the earphone connection mode and the earphone disconnect mode, and the like. . In some embodiments, the current working mode and the target working mode may not belong to the same parallel domain working mode, such as a volume up mode and a headphone connection mode, a volume down mode and a headphone disconnect mode, and the like. Therefore, during the switching process, the current working mode can be switched to the working mode belonging to the same parallel domain, or can be switched to the working mode not belonging to the same parallel domain. A person skilled in the art can customize the correspondence between the working modes according to the product requirements.
综上,通过本实施例提供的耳机工作模式切换方法,其无需按键的参与,用户便可以灵活快速地切换耳机的工作模式,从而提高用户体验感。并且,其还可降低因设计按键而带来的设计成本与困难。In summary, the earphone working mode switching method provided by this embodiment can switch the working mode of the earphone flexibly and quickly without the participation of the button, thereby improving the user experience. Moreover, it can also reduce the design cost and difficulty caused by designing the buttons.
用户操作第一耳机与第二耳机切换当前工作模式时,容易产生误操作。为了降低用户的误操作,本文再提供以下实施例以克服上述缺陷:在一些实施例中,相对运动状态包括第一相对运动状态与第二相对运动状态。一般的,用户操作第一耳机与第二耳机运动时的时间过程中,相对运动状态可以只是一个相对运动状态,亦可以为至少两个相对运动状态。每个相对运动状态可以根据第一耳机与第二耳机之间的相对运动状态在预设时间内是否满足预设运动状态来划分的,举例而言:请参阅图4c,在时间t1至t2时间段内,第一耳机与第二耳机之间的相对距离为S1。在t2至t3时间段内,上述两者的相对距离为S2,其中,S2大于S1。在t3至t4时间段内,上述两者的相对距离为S3,其中,S3小于S1。在t4至t5时间段内,上述两者的相对距离为S4,其中,S4等于S2。在预设逻辑中,当第一耳机与第二耳机之间的相对距离小于Smin时,将当前工作模式切换至第一目标工作模式。或者,当第一耳机与第二耳机之间的相对距离大于Smax时,将当前工作模式切换至第二目标工作模式。其中,在上述各个 相对距离值中,有以下关系:When the user operates the first earphone and the second earphone to switch the current working mode, it is easy to cause an erroneous operation. In order to reduce the user's erroneous operation, the following embodiments are further provided to overcome the above drawbacks: In some embodiments, the relative motion state includes a first relative motion state and a second relative motion state. Generally, during the time when the user operates the first earphone and the second earphone, the relative motion state may be only a relative motion state, or may be at least two relative motion states. Each relative motion state may be divided according to whether the relative motion state between the first earphone and the second earphone meets the preset motion state within a preset time, for example: refer to FIG. 4c, at time t1 to t2 In the segment, the relative distance between the first earphone and the second earphone is S1. In the period from t2 to t3, the relative distance between the two is S2, where S2 is greater than S1. In the period from t3 to t4, the relative distance between the two is S3, wherein S3 is smaller than S1. In the period from t4 to t5, the relative distance between the two is S4, where S4 is equal to S2. In the preset logic, when the relative distance between the first earphone and the second earphone is less than Smin, the current working mode is switched to the first target working mode. Alternatively, when the relative distance between the first earphone and the second earphone is greater than Smax, the current working mode is switched to the second target working mode. Among them, among the above relative distance values, there are the following relationships:
Smin<S1<Smax;Smin<S1<Smax;
S2>Smax;S2>Smax;
S3<Smin;S3<Smin;
S4=S2。S4 = S2.
于是,时间t1至t2时间段对应的相对运动状态并未满足预设运动状态条件,然而,时间t1至t3对应的相对运动状态满足预设运动状态条件,因此,时间t1至t3时间段对应的相对运动状态为第一相对运动状态,在t3时间点处,将当前工作模式切换至第一目标工作模式。Therefore, the relative motion state corresponding to the time period from time t1 to time t2 does not satisfy the preset motion state condition, however, the relative motion state corresponding to the time t1 to t3 satisfies the preset motion state condition, and therefore, the time period corresponding to the time period t1 to t3 The relative motion state is the first relative motion state, and at the time point t3, the current working mode is switched to the first target working mode.
紧接着,时间t3至t4时间段对应的相对运动状态满足预设运动状态条件,因此,时间t3至t4时间段对应的相对运动状态为第二相对运动状态,在t4时间点处,将当前工作模式切换至第二目标工作模式。Then, the relative motion state corresponding to the time period from time t3 to time t4 satisfies the preset motion state condition. Therefore, the relative motion state corresponding to the time period from time t3 to time t4 is the second relative motion state, and at the time point t4, the current working state is The mode is switched to the second target operating mode.
再紧接着,时间t4至t5时间段对应的相对运动状态满足预设运动状态条件,因此,时间t4至t5时间段对应的相对运动状态为第三相对运动状态,在t5时间点处,将当前工作模式切换至第一目标工作模式。Then, the relative motion state corresponding to the time period from time t4 to time t5 satisfies the preset motion state condition. Therefore, the relative motion state corresponding to the time period from time t4 to time t4 is the third relative motion state, and at the time point of t5, the current state will be The working mode is switched to the first target working mode.
请参阅图5,根据相对运动状态,控制第一耳机和/或第二耳机的当前工作模式的切换的过程中,首先,在431中,判断第一相对运动状态是否满足第一预设触发条件。第一预设触发条件由用户根据相对运动状态的表现形式以及产品需求自行定义,例如,第一预设触发条件为“相对速度为正方向时,触发动作”。Referring to FIG. 5, in the process of controlling the switching of the current working mode of the first earphone and/or the second earphone according to the relative motion state, first, in 431, determining whether the first relative motion state satisfies the first preset triggering condition. . The first preset trigger condition is defined by the user according to the expression of the relative motion state and the product requirement. For example, the first preset trigger condition is “trigger action when the relative speed is the positive direction”.
其次,在432中,若第一相对运动状态未满足第一预设触发条件,返回当前工作模式。Next, in 432, if the first relative motion state does not satisfy the first preset trigger condition, the current working mode is returned.
再次,在433中,若第一相对运动状态满足第一预设触发条件,根据第二相对运动状态,控制第一耳机和/或第二耳机的当前工作模式的切换。因此,通过在检测第一次用户操作的第一/第二耳机的相对运动状态满足预设触发条件时,再根据第二次的用户操作真正控制第一耳机和/或第二耳机的当前工作模式的切换。因此,其能够避免用户第一次无意的操作而引起的误触发,从而提高工作模式切换的可靠性。Again, in 433, if the first relative motion state satisfies the first preset trigger condition, switching of the current operating mode of the first earphone and/or the second earphone is controlled according to the second relative motion state. Therefore, by detecting the preset trigger condition when detecting the relative motion state of the first/second earphone of the first user operation, the current operation of the first earphone and/or the second earphone is actually controlled according to the second user operation. Mode switching. Therefore, it can avoid false triggering caused by the user's first unintentional operation, thereby improving the reliability of the work mode switching.
在一些实施例中,根据第二相对运动状态,控制第一耳机和/或第二耳机的当前工作模式的切换的过程中,请参阅图6,首先,在4331中,判断第二相对 运动状态是否满足第二预设触发条件。第二预设触发条件由用户根据相对运动状态的表现形式以及产品需求自行定义,例如,第二预设触发条件为“相对速度为反方向时,触发动作”。In some embodiments, in the process of controlling the switching of the current working mode of the first earphone and/or the second earphone according to the second relative motion state, please refer to FIG. 6. First, in 4331, determining the second relative motion state. Whether the second preset trigger condition is satisfied. The second preset trigger condition is defined by the user according to the expression of the relative motion state and the product requirement. For example, the second preset trigger condition is “trigger action when the relative speed is the reverse direction”.
其次,在4332中,若否,返回当前工作模式。Next, in 4332, if no, return to the current working mode.
再次,在4333中,若是,确定目标工作模式,并切换第一耳机和/或第二耳机工作在目标工作模式。在一些实施例中,用户预先构建各类工作模式与相对运动状态之间的关联表,第一/第二耳机根据相对运动状态查找对应的目标工作模式,并将当前工作模式切换至目标工作模式。Again, in 4333, if yes, the target mode of operation is determined and the first headset and/or the second headset are switched to operate in the target mode of operation. In some embodiments, the user pre-builds an association table between various working modes and relative motion states, and the first/second earphone searches for a corresponding target working mode according to the relative motion state, and switches the current working mode to the target working mode. .
在一些实施例中,确定目标工作模式的过程中,请参阅图7,首先,在43331中,预设满足第一预设触发条件的第一相对运动状态为第一事件,以及满足第二预设触发条件的第二相对运动状态为第二事件。In some embodiments, in the process of determining the target working mode, refer to FIG. 7. First, in 43331, the first relative motion state that satisfies the first preset trigger condition is preset as the first event, and the second pre-satisfaction is satisfied. The second relative motion state of the trigger condition is set to be the second event.
其次,在43332中,将第一事件与第二事件作为组合事件。Second, in 43332, the first event and the second event are combined events.
再次,在43333中,在预设时间内,统计组合事件的出现次数。此处的预设时间可以由用户自定义。Again, in 43333, the number of occurrences of the combined event is counted within a preset time. The preset time here can be customized by the user.
最后,在43334中,根据组合事件的出现次数,确定目标工作模式。Finally, in 43334, the target mode of operation is determined based on the number of occurrences of the combined event.
因此,用户通过轮番多次操作第一耳机与第二耳机,方可确定目标工作模式,从而极大提高工作模式切换的可靠性。Therefore, the user can determine the target working mode by operating the first earphone and the second earphone multiple times, thereby greatly improving the reliability of the working mode switching.
在一些实施例中,根据组合事件的出现次数,确定目标工作模式的过程中,请参阅图8,首先,在433341中,判断组合事件的出现次数是否大于预设组合阈值。该预设组合阈值由用户自定义,例如可以为2等等。In some embodiments, in the process of determining the target working mode according to the number of occurrences of the combined event, please refer to FIG. 8. First, in 433341, it is determined whether the number of occurrences of the combined event is greater than a preset combined threshold. The preset combination threshold is user-defined, for example, it can be 2 or the like.
其次,在433342中,若大于,确定目标工作模式;Secondly, in 433342, if it is greater than, the target working mode is determined;
再次,在433343中,若小于,返回当前工作模式。Again, in 433343, if it is less than, it returns to the current working mode.
