最近这几年随着人们健康生活意识的提高,健身热潮席卷全国,也带动了运动蓝牙耳机的发展。但严格意义上来讲,运动无线蓝牙耳机还未真正做到完全“无线”,还是需要一根物理线将两个耳机头连接形成立体声效果,在此背景下,TWS分离式蓝牙耳机诞生。
TWS为True Wireless Stereo的缩写,是真正无线立体声的意思。在实际使用时,可单可双,完全没有任何有线束缚。同类型最著名的当属苹果的Airpods,但AirPods高昂的价格和糟糕的适配性,让很多人望而却步。
现有的各大耳机厂商也陆续推出自己的TWS耳机。然而,现有的无线音频设备的配对方式有两种,一种需要分别对2个无线音频设备分别进行操作,让其进入配对状态,然后检测到相互处于配对状态后再进行匹配;另一种是通过PC或者手机对各无线音频设备写入配对信息,完成匹配。这两种方法,操作流程复杂且有一定的技术难度。尤其是第一种方法,在多组无线音频设备配对时,容易发生相互干扰,导致配对失败。

本发明目的的实现、功能特点及优点将结合实施例,参照附图做进一步说明。
本发明的最佳实施方式
应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
参照图1,本发明实施例提供了一种无线音频设备配对方法,包括:
S10、第一无线音频设备与第二无线音频设备建立临时连接,所述第一无线音频设备与所述第二无线音频设备互为其查找到的最强RSSI信号强度的无线音频设备;
S20、向所述第二无线音频设备发送第一配对信息,并接收所述第二无线音频设备发送的第二配对信息;
S30、若确定所述第一配对信息及所述第二配对信息满足预设配对条件,则与所述第二无线音频设备进行配对。
本实施例中,无线音频设备可以是无线蓝牙耳机,也可以是无线蓝牙音箱,或者其他无线音频设备。第一无线音频设备和第二无线音频设备一般是指配对的两个无线音频设备,如左耳耳机和右耳耳机,或配套的两只蓝牙立体声音箱。RSSI,是英文词语Received Signal Strength Indication的缩写,中文含义为接收的信号强度指示,属于无线发送层的可选部分,用来判定链接质量,以及是否增大广播发送强度。
步骤S10中,只有当第一无线音频设备和第二无线音频设备互为检测到的RSSI最强的匹配设备,两者才能建立临时连接。换句话讲,就是第一无线音频设备和第二无线音频设备要放在足够接近的地方,使彼此均为对方RSSI最强的匹配设备,这样两个设备才建立临时连接。这样可以排除掉RSSI不是最强的匹配设备,减少匹配时间。
步骤S20中,在第一无线音频设备和第二无线音频设备建立临时连接之后,两个无线音频设备会交换彼此的配对信息,以确定两者是否是同型号的设备。第一无线音频设备接收到第二无线音频设备发送的第二配对信息。第二无线音频设备接收到第一无线音频设备发送的第一配对信息。
步骤S30中,第二无线音频设备会判断接收到的第一配对信息是否满足第一预设条件,第一无线音频设备会判断接收到的第二配对信息是否满足第二预设条件。若两个条件同时满足,则说明第一无线音频设备与第二无线音频设备是适配的,此时,两个设备配对成功。当两个无线音频设备配对成功后,可作为一个整体与智能手机或带有蓝牙功能的笔记本连接,然后在无线音频设备上实现播放功能。
可选的,步骤S10包括:
第一无线音频设备接收触发指令,启动RSSI扫描模式,查找最强RSSI信号强度的第二无线音频设备;
发送第一临时连接请求至所述第二无线音频设备,以及判断是否接收到所述第二无线音频设备的第二临时连接请求;
若接收到所述第二临时连接请求,则与所述第二无线音频设备建立临时连接。
本实施例中,第一无线音频设备与第二无线音频设备建立临时连接是通过以下方式进行的:第一无线音频设备接收到触发指令,启动RSSI扫描模式,查找最强RSSI信号强度的无线音频设备。若第一无线音频设备查找到的最强RSSI信号强度的无线音频设备为第二无线音频设备,则发送第一临时连接请求至第二无线音频设备。同时,第二无线音频设备接收到触发指令,启动RSSI扫描模式,查找最强RSSI信号强度的无线音频设备。若第二无线音频设备查找到的最强RSSI信号强度的无线音频设备为第二无线音频设备,则发送第二临时连接请求至第一无线音频设备。当第一无线音频设备接收到第二临时连接请求时,则与第二无线音频设备建立临时连接。
可选的,步骤S10包括:
第一无线音频设备接收触发指令,启动RSSI扫描模式,查找最强RSSI信号强度的第二无线音频设备;
发送第一临时连接请求至所述第二无线音频设备;
若接收到所述第二无线音频设备响应所述第一临时连接请求的接受信息,则与所述第二无线音频设备建立临时连接。
本实施例中,第一无线音频设备与第二无线音频设备建立临时连接还可以通过以下方式进行:第一无线音频设备接收到触发指令,启动RSSI扫描模式,查找最强RSSI信号强度的无线音频设备。若第一无线音频设备查找到的最强RSSI信号强度的无线音频设备为第二无线音频设备,则发送第一临时连接请求至第二无线音频设备。若接收到第二无线音频设备响应所述第一临时连接请求的接受信息,则与所述第二无线音频设备建立临时连接。
可选的,所述第一无线音频设备接收触发指令,启动RSSI扫描模式,查找最强RSSI信号强度的第二无线音频设备的步骤包括:
所述第一无线音频设备接收触发指令,启动RSSI扫描模式,查找RSSI信号强度大于预设阈值的无线音频设备;
将查找到的最强RSSI信号强度的无线音频设备确定为所述第二无线音频设备。
本实施例中,第一无线音频设备和第二无线音频设备均接收触发指令。触发指令可以指无线音频设备从待机状态转化为工作状态,也可以指无线音频设备从关机状态转化为工作状态。以第一无线音频设备为例,当第一无线音频设备进入工作状态时,会启用RSSI扫描模式,检测需要匹配的第二无线音频设备发射的信号。第一无线音频设备启用RSSI扫描模式设置了RSSI信号强度阈值。只有大于预设的RSSI信号强度阈值的无线音频设备,第一无线音频设备才会与之配对。这样可以保证配对的无线音频设备有足够接近的距离,同时避免出现搜索到较远处无线音频设备的情况。可以将第一无线音频设备和第二无线音频设备的RSSI信号强度阈值设置为-50dbm。经试验,当第一无线音频设备和第二无线音频设备放在同一个充电盒内时,无论是第一无线音频设备,还是第二无线音频设备,接收到的RSSI信号强度均大于-50dbm。步骤S22中,若第一无线音频设备和第二无线音频设备获得的最强RSSI信号强度小于-50dbm时,则继续扫描。此时第一无线音频设备和第二无线音频设备会发出一些提醒,如灯光闪烁或蜂鸣响声,提醒用户将两个无线音频设备放得更靠近一些。
可选的,步骤30之后,还包括:
存储所述第二配对信息。
本实施例中,当第一无线音频设备与第二无线音频设备配对完成之后,在第一无线音频设备上保存第二无线音频设备发送的第二配对信息,在第二无线音频设备上保存第一无线音频设备发送的第一配对信息。当两个无线音频设备保存有对方的配对信息时,减少了配对信息匹配的过程,设备之间的配对时间会大大缩小。
可选的,所述第一无线音频设备接收触发指令,启动RSSI扫描模式,查找RSSI信号强度大于预设阈值的无线音频设备的步骤之后,还包括:
若查找的RSSI信号强度低于预设阈值,则发出提醒信号。
本实施例中,查找的RSSI信号强度低于预设阈值,说明没有符合条件的无线音频设备可以匹配,此时,第一无线音频设备可发出提醒信号,提醒用户配对未完成。
可选的,所述发出提醒信号的步骤包括:
以闪烁的红色闪光发出所述提醒信号。
本实施例中,可以在第一无线音频设备上设置小型的LED灯,LED灯的颜色可以为红色。当配对未成功时,以闪烁的红色闪光发出提醒信号,提醒用户配对未完成。
可选的,所述向所述第二无线音频设备发送第一配对信息,并接收所述第二无线音频设备发送的第二配对信息的步骤之后,还包括:
若所述第一配对信息及所述第二配对信息未满足预设配对条件,则发出提醒信号。
本实施例中,若第二无线音频设备与第一无线音频设备的型号不匹配,则两个设备不能配对,此时会发出提醒信号,提醒用户匹配未成功。
可选的,所述第一无线音频设备接收触发指令之前,还包括:
通过按键或数据线连接产生触发指令。
本实施例中,第一无线音频设备和第二无线音频设备设置有按键和数据线连接口。在一实施例中,按住第一无线音频设备的按键,设备会产生触发指令,该触发指令可使第一无线音频设备进入RSSI扫描模式。在另一实施例中,第一无线音频设备和第二无线音频设备放置于充电盒内,第一无线音频设备的数据线连接口与充电盒的充电接触点接触,第二无线音频设备的数据线连接口与充电盒的另一个充电接触点接触。两个充电接触点用数据线连接。充电盒设置有霍尔开关,设置在数据线上。当充电盒关闭时,霍尔开关处于关闭状态,数据线不连通。打开充电盒,霍尔开关处于开启状态,数据线连通。当数据线连通,两个无线音频设备会产生触发指令。
参照图2,本发明实施例还提出了一种无线音频设备,作为第一无线音频设备使用,包括:
