本申请实施例定义了附图的坐标系。x方向、y方向和z方向两两垂直,z方向可以理解为保护壳本体的厚度方向,y方向可以理解为保护壳本体的宽度方向,x方向可以理解为保护壳本体的长度方向,或者,y方向可以理解为保护壳本体的长度方向,x方向可以理解为保护壳本体的宽度方向。示例性地,在本申请实施例中,以y方向为保护壳本体的长度方向,x方向为保护壳本体的宽度方向为例,对保护壳的结构进行说明。
需要说明的是,上述描述的保护壳本体的厚度方向、长度方向和宽度方向也可以称为保护壳的厚度方向、长度方向和宽度方向。
本申请实施例还定义了保护壳本体的六个面,分别是:沿z方向(保护壳本体的厚度方向)相对设置的正面和背面,以及,与正面和背面都连接的四个侧面。保护壳本体的正面可以理解为与移动设备的屏幕朝向相同的表面,当移动设备被正常使用时,移动设备的屏幕以及保护壳本体的正面都朝向用户,对应地,当移动设备被正常使用时,保护壳本体的背面背朝用户。保护壳本体的四个侧面依次连接,为了便于描述,将四个侧面分别记为第一侧面、第二侧面、第三侧面和第四侧面,其中,第一侧面和第二侧面相对设置,第三侧面和第四侧面相对设置。其中,第一侧面和第二侧面可以沿着y方向(例如,保护壳本体的长度方向)相对设置,第三侧面和第四侧面可以沿x方向(例如,保护壳本体的宽度方向)相对设置,或者,第一侧面和第二侧面可以沿x方向相对设置,第三侧面和第四侧面可以沿y方向相对设置。为了便于描述,以第一侧面和第二侧面沿y方向相对设置,第 三侧面和第四侧面沿x方向相对设置为例,对本申请实施例的保护壳做描述。
此外,本申请实施例还定义了保护壳本体的前侧、后侧,第一侧、第二侧、第三侧和第四侧。前侧和后侧是保护壳本体在z方向分布上的两侧,前侧可以理解为保护壳本体的正面朝向的一侧,后侧可以理解为保护壳本体的背面朝向的一侧,第一侧和第二侧是保护壳本体在y方向上的两侧,第三侧和第四侧是保护壳本体在x方向分布的两侧。
需要说明的是,上述描述的保护壳本体的前侧、后侧、第一侧、第二侧、第三侧和第四侧也可以称为保护壳的前侧、后侧、第一侧、第二侧、第三侧和第四侧。
参考图1和图2,保护壳10包括保护壳本体11,保护壳本体11上设置有容纳槽111,容纳槽111的四周被保护壳本体11围合,移动设备可套装在容纳槽111中,以对移动设备起到保护作用。保护壳本体11上还设置有开孔112,当保护壳10安装在移动设备上时,开孔112避让移动设备的进声通道,以便于外部的声音信号通过开孔112和移动设备的进声通道进入移动设备的内部,以获得声音信号。应理解,开孔112的位置和数量可以根据不同类型的移动设备设置。示例性地,开孔112可以设置在保护壳本体11的第一侧面1101,或者,开孔112可以设置在保护壳本体11的第二侧面1102。示例性地,保护壳本体11包括一个或多个开孔112,例如,图1和图2示出的保护壳本体11可包括两个开孔112,两个开孔112分别设置在保护壳本体11的第一侧面1101和第二侧面1102。
结合图3和图4,保护壳10还包括电路组件13,固定连接在保护壳本体11内,电路组件13上电连接有各种器件,示例性地,器件可以焊接在电路组件13上。
在一些实施例中,为了便于加工和装配,保护壳本体11可以由两部分组成,参考图3和图4,该两部分可分别定义为前壳本体11A和后壳本体11B,前壳本体11A和后壳本体11B可通过例如焊接或粘接等方式固定连接。其中,前壳本体11A上设置有容纳槽111,以及,前壳本体11B内固定有电路组件13,后壳本体11B可用于保护电路组件13以及电连接在电路组件13上的各种器件。
继续参考图1和图2,保护壳本体11上设置有多个进声通道114,以及,保护壳11包括多个录音器件12,多个录音器件12安装在保护壳本体11内。多个进声通道114与多个录音器件12一一对应,一个进声通道114对应一个录音器件12,进声通道114的一端与对应的录音器件12相连通,进声通道114的另一端形成进声孔,朝向保护壳本体11的外侧。这里,进声通道114与对应的录音器件12可形成声学结构,用于采集外部的声音信号。
在本申请实施例中,进声通道114可以设置在保护壳本体11的任意区域,以及,进声通道114的另一端形成的进声孔的朝向可以是任意的,只要能接收外部的声音信号即可。
基于用户手持移动设备的习惯,一般情况下,会尽可能采集分布在移动设备的前侧或后侧的声音信号,或,采集分布在移动设备的前侧和后侧的声音信号。那么,对于固定在移动设备上的保护壳11而言,同理,会尽可能采集分布在保护壳11的前侧或后侧的声音信号,或,采集分布在保护壳11的前侧和后侧的声音信号。
在本申请实施例中,为了尽可能采集到分布在保护壳11的前侧和后侧的声音信号,多个进声通道114中的一部分进声通道114的进声孔朝向保护壳11的前侧,将该部分记为第一部分,另一部分进声通道114的进声孔的朝向保护壳11的后侧,将该部分记为第 二部分。为了便于描述,将第一部分中的进声通道114记为进声通道114A,对应进声通道114A的录音器件12记为录音器件12A,将第二部分中的进声通道114记为进声通道114B,对应进声通道114B的录音器件12记为录音器件12B。
参考图1和图2,第一部分可以包括一个或多个进声通道114A,第二部分可以包括一个或多个进声通道114B,此处都不做任何限定。示例性地,在图1和图2中,第一部分可以包括2个进声通道114A,第二部分可以包括8个进声通道114B。
第一部分的进声通道114A的数量和第二部分的进声通道114B的数量可以基于录音的场景设计。例如,在拍摄视频的场景中,用户拍摄移动设备的后侧的视频的场景可能多于用户拍摄移动设备的前侧的视频的场景,那么,可以将第一部分的进声通道114A的数量设计的少,将第二部分的进声通道114B的数量设计的多,如图1和图2所示。再例如,在电话录音的场景中,可以将第一部分的进声通道114A的数量设计的多,将第二部分的进声通道114B的数量设计的少。
在第一部分包括多个进声通道114A的实施例中,多个进声通道114A间隔设置。为了便于处理通过各个进声通道114A和对应的录音器件12A采集的声音信号,减少处理的计算量,示例性地,多个进声通道114A可以对称设置,例如,图1和图2所示的两个进声通道114A沿着x方向对称设置。此外,为了采集具有差异性的声音信号,示例性地,多个进声通道114A中任意两个进声通道114A之间的距离不宜太近。
参考图3,第一部分中的进声通道114A的一端与对应的录音器件12A相连通,进声通道114A的另一端形成进声孔114A-1,进声孔114A-1朝向保护壳10的前侧,其中,进声孔114A-1设置在保护壳本体11的正面1103上。
在进声通道114A的进声孔114A-1朝向保护壳10的前侧的实施例中,考虑到录音器件12A的位置以及加工难以程度等情况,进声通道114A可以由多段通道组成。
在一些实施例中,继续参考图3,进声通道114A包括第一通道114A-2、第二通道114A-3和第三通道114A-4,第二通道114A-3的两端分别与第一通道114A-2和第三通道114A-4相连通,第一通道114A-2的一端形成进声孔114A-1,进声孔114A-1朝向保护壳10的前侧,第三通道114A-4的另一端与对应的录音器件12A相连通。
在该实施例中,示例性地,第一通道114A-2和第三通道114A-4平行于保护壳本体11的厚度方向(z方向),第二通道114A-3垂直于保护壳本体11的厚度方向(z方向)。
继续参考图3,在保护壳本体11包括前壳本体11A和后壳本体11B的实施例中,第二通道114A-3设置在后壳本体11B上,第一通道114A-2与第二通道114A-3相连通延伸至前壳本体11A的正面1103,第三通道114A-4与第二通道114A-3相连通延伸至录音器件12A。
需要说明的是,第一通道114A-2平行于保护壳本体11的厚度方向,表示的是,第一通道114A-2的中心轴线平行于保护壳本体11的厚度方向,或者说,第一通道114A-2的延伸方向平行于保护壳本体11的厚度方向。同理,第三通道114A-4平行于保护壳本体11的厚度方向的解释同第一通道114A-2平行于保护壳本体11的厚度方向的解释。第二通道114A-3垂直于保护壳本体11的厚度方向,表示的是,第二通道114A-3的中心轴线垂直于保护壳本体11的厚度方向,或者说,第二通道114A-3的延伸方向垂直于保护壳本体11的厚度方向。
应理解,第一通道114A-2、第三通道114A-4也可以不平行于保护壳本体11的厚度方向,第二通道114A-3也可以垂直于保护壳本体11的厚度方向,此处不做任何限定。例如,第一通道114A-2可以沿着任意方向延伸至保护壳本体11的正面1103,形成位于正面1103的进声孔114A-1,第三通道114A-4可以沿任意方向延伸至对应的录音器件12A上,第二通道114A-3的两端分别与第一通道114A-2和第三通道114A-4相连通。
还应理解,进声通道114A也可以不采用上述三段通道组合的结构,例如,进声通道114A可以包括相连通的第一通道114A-2和第二通道114A-3,不需要第三通道114A-4,其中,第一通道114A-2的一端形成的进声孔114A-1朝向保护壳10的前侧,第二通道114A-3的一端与录音器件12A相连通。
在进声通道114A包括多段通道的实施例中,进声通道114A中有一段通道最靠近保护壳本体11的背面1104,以图3所示的结构为例,第二通道114A-3最靠近背面1104。在设置进声通道114A时,为了便于加工,可以先在保护壳本体11上加工进声通道114A,不过,最靠近背面1104的一段通道会外露,保护壳10的防水防尘效果都不好,影响保护壳10内的器件。因此,可以在保护壳本体11的背面1104上设置有盖板14,以形成封闭的进声通道114A。示例性地,盖板14可以粘接在背面1104上。
继续以图3所示的结构为例,进声通道114A包括三段通道,第二通道114A-3最靠近背面1104,盖板14设置在背面1104且位于第二通道114A-3的一侧,以盖合第二通道114A-3,形成封闭的进声通道114A。
在本申请实施例中,进声通道114A的进声孔114A-1可以设置在保护壳本体11的正面1103中除容纳槽111的内壁以外的任意区域。示例性地,参考图1,进声通道114A的进声孔114A-1设置在正面1103中沿x方向分布的一个或两个端部区域中;示例性地,参考图5,进声通道114A的进声孔114A-1设置在正面1103中沿y方向分布的一个或两个端部区域中。
参考如图4,第二部分中的进声通道114B中的一端与对应的录音器件12B相连通,进声通道114B的另一端形成进声孔114B-1,进声孔114B-1朝向保护壳10的后侧,其中,进声孔114B-1设置在背面1104上。
在一些实施例中,继续参考图4,进声通道114B平行于保护壳本体11的厚度方向(z方向)。也就是说,进声通道114B是一个与保护壳本体11的厚度方向平行设置的直通道。这样,可以缩短进声通道114B的路径,有利于减少声音的损耗,减少由于谐振导致的声音的失真,且节约了保护壳本体11的内部空间。此外,由于进声通道114B的进声孔114B-1设置在保护壳本体11的背面1104,很容易设置与保护壳本体11的厚度方向平行的直通道。
继续参考图4,在保护壳本体11包括前壳本体11A和后壳本体11B的实施例中,进声通道114B可以设置在后壳本体11B上且延伸至背面1104,在背面1104上形成进声孔114B-1。
需要说明的是,进声通道114B平行于保护壳本体11的厚度方向,表示的是,进声通道114B的中心轴线平行于保护壳本体11的厚度方向,或者说,进声通道114B的延伸方向平行于保护壳本体11的厚度方向。
应理解,上文所述的进声通道114的进声孔的朝向仅为示意性说明,本申请实施例不 限于此。
示例性地,保护壳本体11的多个进声通道114的进声孔都朝向保护壳10的前侧,形成例如图3所示的具有多段通道的进声通道114A。
示例性地,保护壳本体11的多个进声通道114的进声孔都朝向保护壳10的后侧,形成例如图4所示的进声通道114B。
示例性地,参考图6,多个进声通道114中的一个或多个进声通道114的进声孔可以朝向保护壳10的第一侧或第二侧。为了便于区分,将进声孔朝向第一侧的进声通道114记为114C,将进声孔朝向第二侧的进声通道114记为114D。
示例性地,参考图7,多个进声通道114中的一个或多个进声通道114的进声孔可以朝向保护壳10的第三侧或第四侧。为了便于区分,将进声孔朝向第三侧的进声通道114记为114E,将进声孔朝向第四侧的进声通道114记为114F。
由于保护壳本体11上设置了多个进声通道114,外部的水或灰尘等杂质不可避免会进入到保护壳10的内部,对保护壳10内部的器件造成损害。因此,为了有效地防止外部杂质进入保护壳12的内部,例如,可放置灰尘、碎屑、液体等杂质进入保护壳12的内部。在一些实施例中,继续参考图3和图4,保护壳10内还设置有密封件15,密封件15设置在进声通道114和对应的录音器件12之间,示例性地,密封件15的上表面与录音器件12的下表面密封贴合,这样,密封件15可以有效地防止杂质从进声通道114进入保护壳10的内部,对保护壳10内部的器件起到保护作用。
示例性地,密封件15可以包括泡棉和防护网布,或者,密封件15可以包括泡棉或防护网布。
以上,结合图1至图7,从声学结构描述了本申请实施例的保护壳,以下,结合图8至图12,从信号的传输以及信号的处理的方面对本申请实施例的保护壳做详细说明。
在一些实施例中,参考图8,保护壳10包括处理单元17,用于与保护壳10内部的器件(例如,录音器件144)连接,用于对多个录音器件12采集的多路声音信号进行处理,将处理后的声音信号发送至移动设备20。
为了便于描述,以保护壳10包括N个录音器件12以及对应的N个进声通道144为例,对本申请实施例做说明。应理解,一个录音器件12和对应的进声通道114采集的一路声音信号。
参考图8,N个录音器件12和对应的N个进声通道144总共采集N路声音信号,该N路声音信号被传输至处理单元17中。
参考图8,处理单元17用于对接收到的N路声音信号做相关处理,输出处理后的声音信号,该处理后的声音信号被传输至第一接口161中。
在一些实施例中,若录音器件12输出的声音信号为模拟信号,则处理单元17可用于进行模数转化(A/D),即,将模拟信号转化为数字信号。
在另一些实施例中,处理单元17还用于对数字信号进行编码格式的转换,将数字信号转化为脉冲编码调制(pulse code modulation,PCM)格式的码流,得到N个声音信号的码流。示例性地,码流的采样率可以为48kHz,位宽为16bit。码流的采样率和位宽也可以称为声音信号的采样率和位宽,两种描述可替换。
参考图9,在另一些实施例中,处理单元17还用于对将该N路声音信号做合并处理, 得到处理后的声音信号,该处理后的声音信号包括M组声音信号,M是小于N的整数。这样,可以通过高码率传输声音信号,提高传输效率。
M组声音信号中每组声音信号包括多路声音信号,任意两组声音信号中包括的声音信号的数量可以相同,也可以不同,此处不做任何限定。以N=10,M=2为例,例如,第一组声音信号中包括5路声音信号,第二组声音信号也包括5路声音信号;再例如,第一组声音信号中包括4路声音信号,第二组声音信号包括6路声音信号。
在一些方式中,M组声音信号中每组声音信号的采样率大于N路声音信号中每路声音信号的采用率。示例性地,每组声音信号包括Q路声音信号,每组声音信号的采样率大于或等于Q路声音信号的采样率的总和。例如,每组声音信号包括4路声音信号,每路声音信号的采用率为48kHz,则每组声音信号的采样率大于或等于192kHz。
在另一些方式中,M组声音信号中每组声音信号的位宽大于N路声音信号中每路声音信号的位宽。示例性地,将每组内各个声音信号的码流拼接在一起,填入高码率的帧中,每个帧的位宽即为每组声音信号的位宽,若声音信号的码流不够填满完整的帧,则在空位处填补“0”或“1”。
在合并N路声音信号过程中,上述两种方式可以结合使用,也可以单独使用,本申请实施例不做任何限定。
假设,N=10,M=2,结合图9,将上述两个方式结合使用,对处理后的声音信号做说明。
示例性地,参考图9,10路声音信号中每路声音信号的码流的采用率为48kHz,合并后的2组声音信号中每组声音信号的码流的采用率大于48kHz,例如,可以为192kHz。当然,合并后的每组声音信号的码流的采样率也可以为96kHz、144kHz、288kHz等,本申请实施例不做任何限定。假设,每组声音信号(或一个帧)的位宽为24bit,每路声音信号的位宽为16bit,以合并后的第二组声音信号为例,5路声音信号的码流拼接在一起,填入位宽为24bit的帧中,对于未填满的第四帧,填充“0”。
参考图8和图9,保护壳10包括第一接口161,可用于与处理单元17连接,也用于和移动设备20的第三接口201通过有线或无线的方式连接,以实现保护壳10与移动设备20之间的有线或无线连接,以在保护壳10和移动设备20之间传输信号。该信号可以包括声音信号,也可以包括电源信号。
在第一接口161用于和第三接口201有线连接时,可在保护壳10和移动设备20之间传输声音信号和电源信号,在第一接口161用于和第三接口201无线连接时,可在保护壳10和移动设备20之间传输声音信号。
在一些实施例中,参考图8和图9,保护壳10可以通过第一接口161将处理后的声音信号发送至移动设备20的第三接口201,以便于移动设备20处理声音信号。
第一接口161将接收到的该处理后的声音信号发送至移动设备20的第三接口201,以便于移动设备20对声音信号做相关的算法处理,以达到好的录音性能。关于移动设备20对声音信号的相关处理,后续做详细说明。
在另一些实施例中,移动设备20还可以通过第三接口201和第一接口161为保护壳10传输电源信号,以为保护壳10供电。
应理解,上述处理单元17对多路声音信号的处理仅为示意性说明,不应对本申请实 施例构成限定。例如,处理单元17也可以不需要对N路声音信号做合并处理,可以将该N路声音信号通过第一接口161发送至移动设备20的第三接口201。
以下,分别从保护壳10与移动设备20之间有线连接和无线连接的角度,结合图10至图12,对本申请实施例做详细说明。
在保护壳10和移动设备20之间有线连接的方式中,目前的移动设备大多数支持通用串行总线(universal serial bus,USB)协议,为了较好地适用于移动设备的USB协议,在一些实施例中,保护壳10的各个接口也支持USB协议,下面,以接口为USB接口为例,对有线连接的方式做说明。
在该实施例中,参考图10和图11,保护壳10包括第一USB接口1611,可作为第一接口161的一例,移动设备20包括第三USB接口2011,可作为第三接口201的一例。在一些实施例中,继续参考图11,第一USB接口伸出保护壳本体11,用于插入移动设备20的第三USB接口中。
在移动设备20支持USB协议的实施例中,大多数移动设备20的内部通过两声道传输声音信号,该两声道可以记为左声道和右声道,因此,参考图11,处理单元17将来自录音器件144的N路声音信号合并为两组声音信号,一组声音信号记为左声道声音信号,另一组声音信号记为右声道声音信号,左声道声音信号通过第一USB接口1621和第三USB接口2011被传输至移动设备20的左声道,右声道声音信号通过第一USB接口1621和第三USB接口2011被传输至移动设备20的右声道。关于左声道声音信号和右声道声音信号的相关描述可参考上文所述的合并后的第一组声音信号和第二组声音信号的详细描述,不再赘述。

在保护壳10包括第二USB接口1621的实施例中,第二USB接口1621还用于和外部的外接设备连接,以在保护壳10和外接设备之间传输数据。在第一USB接口1611、第二USB接口1621和第三USB接口2011结合使用的实施例中,在通过第二USB接口1621在保护壳10和外接设备传输数据的同时,还可以通过第二USB接口1621、第一USB接口1611以及第三USB接口2011在移动设备20和外接设备之间传输数据。示例性地,该 外接设备可以是U盘,硬盘、键盘等设备。
本申请实施例的保护壳上设置的第二USB接口,不仅可以为保护壳传输电能,也可以在保护壳和外接设备之间传输数据,而且,更重要地是,第二USB接口、第一USB接口和移动设备的第三USB接口之间结合使用,也可以为移动设备提供电能,同时,可在外接设备和移动设备之间传输数据。这样,不仅为保护壳提供了一种传输电能和数据的方式,而且,能够更为方便地为移动设备提供电能以及在外接设备和移动设备之间传输数据;此外,第二USB接口的设置可以避免在保护壳上额外设置用于避让移动设备的第三USB接口的开孔,外形相对美观,少量的开孔也可以提高防尘防水的效果。
在保护壳10包括第二USB接口1621的实施例中,保护壳10还可以包括USB集线器,USB集线器与第二USB接口1621连接,用于将移动设备20的第三USB接口2011扩展为可同时支持第一USB接口1611和第二USB接口1621的接口,或者说,USB集线器用于将第三USB接口2011扩展为可同时连接保护壳10与外接的充电设备或外接设备的接口。
在保护壳10与移动设备20之间无线连接的方式中,保护壳10的第一接口161和移动设备20的第三接口201都可以是无线通信模块,用于在保护壳10和移动设备20之间传输数据。

此外,继续参考图12,处理单元17对N路声音信号做处理后,也可得到两组声音信号,分别是左声道声音信号和右声道声音信号,左声道声音信号和右声道声音信号,通过第一USB接口1621和第三USB接口2011分别被传输至移动设备20的左声道和右声道。关于左声道声音信号和右声道声音信号的相关描述可参考上文所述的合并后的第一组声音信号和第二组声音信号的详细描述,不再赘述。
本申请实施例的无线通信模块(第一无线通信模块1612、第三无线通信模块1622)可以提供应用在电子设备上的包括无线局域网(wireless local area networks,WLAN)(如无线保真(wireless fidelity,Wi-Fi)网络),蓝牙(bluetooth,BT),全球导航卫星系统(global navigation satellite system,GNSS),调频(frequency modulation,FM),近距离无线通信技术(near field communication,NFC),红外技术(infrared,IR)等无线通信技术。
应理解,第一无线通信模块1621与第三无线通信模块2011支持同类型的无线通信技术。
在无线传输过程中,为了使得合并处理后得到的声音信号的传输能够适应无线传输,在一些实施例中,处理单元17还用于对处理后的声音信号做压缩编码处理,以降低声音信号的码流的码率,减少对传输带宽的要求。例如,对声音信号做压缩编码处理后的声音信号可以是高级音频编码(advanced audio coding,AAC)格式的码流。
在保护壳10和移动设备20之间无线连接的实施例中,继续参考图12,在一些实施例中,保护壳20还包括无线供电模块1622,用于和保护壳10内的各个器件连接,也用于和外部的无线供电模块连接,无线供电模块1622接收充电输入,以为保护壳10供电, 如图12中加粗的带有箭头的线。示例性地,无线供电模块1622可以是无线充电线圈。
在一些实施例中,外部的无线供电模块可以是无线充电器中的无线供电模块,也就是说,无线供电模块1622可以通过无线充电器为保护壳10供电。在另一些实施例中,在移动设备20具有无线供电模块的结构中,该外部的无线供电模块也可以是移动设备的无线供电模块,也就是说,无线供电模块1622可以通过移动设备20为保护壳10供电。
应理解,上述通过无线供电模块1622为保护壳10供电的实施例仅为示意性说明,示例性地,保护壳10上也可以设置用于和外部的充电设备有线连接的接口,例如,保护壳10上可以设置例如图11所示的第二USB接口1621。
以下,结合图13至图14,对移动设备20对声音信号的处理做说明。
参考图13,移动设备20包括第三接口201和处理单元210。第三接口201用于和保护壳10的第一接口161通过无线或有线方式连接,以实现移动设备20与保护壳10之间的无线或有线连接。处理单元210用于处理声音信号。

若低功耗模式是保护壳10的录音器件144处于断电状态,则在保护壳10开启录音模式之前,需要首先恢复录音器件144的供电状态。
