本说明书中，声学装置可以为助听器、听音手环、耳机、音箱、智能眼镜等具有声学输出能力的设备。在一些实施例中，声学装置1可以是骨传导助听器、骨传导听音手环、骨传导耳机、骨传导音响、骨传导智能眼镜等基于骨传导实现声学输出的设备。本说明书中以声学装置1为骨传导助听器为例进行示例性的说明。
助听器是一种小型的扩音器，把原本听不到的声音加以扩大，再利用听障者的残余听力，使声音能被送到大脑听觉中枢。但是由于听障者听力受损或者退化，导致耳道传音方式对听障者的听觉效果改善比较有限。在一些实施例中，可以将骨传导技术应用于助听器，骨传导技术能够突破传统的耳道传音方式，可以有效改善听障者的听觉效果，而且使得听障者能够接收到更清晰更稳定的声音。
骨传导助听器能够将音频转化成不同频率的机械振动，以人的骨头作为传递机械振动的介质，进而将机械振动传递到听觉神经，如此可以使得使用者不通过耳朵的外耳道和鼓膜也能够接收到声音。在一些实施例中，将骨传导技术应用于助听器，能够有效改善耳道传音方式的缺陷，请参照如下实施例的示例性描述。
图1是根据本申请的一些实施例所示的声学装置的结构示意图。如图1所示，在一些实施例中，声学装置1可以包括扬声器组件10和耳挂组件20。耳挂组件20可以与扬声器组件10相连接，耳挂组件20可以挂设于使用者的耳部，以使得扬声器组件10可以被挂设于使用者的耳朵上。在一些实施例中，扬声器组件10的数量可以是两个，耳挂组件20的数量也可以是两个，两个扬声器组件10和两个耳挂组件20可以一一对应的设置。扬声器组件10和耳挂组件20的数量可以根据实际的使用需求来进行选择。例如，当声学装置是骨传导助听器时，如果使用者是单侧耳朵听力损失，扬声器组件10和耳挂组件20的数量可以是一个，如果使用者是双侧耳朵听力损失，扬声器组件10和耳挂组件20的数量可以是两个。在一些实施例中，声学装置还可以包括后挂组件30，后挂组件可以连接在两个耳挂组件20之间，可以使得耳挂组件20更加稳定地挂设于使用者的耳朵上。
在一些实施例中，声学装置1可以包括两个扬声器组件10、两个耳挂组件20以 及后挂组件30。其中，两个耳挂组件20的一端分别对应连接一个扬声器组件10，也即是两个耳挂组件20各自连接一个扬声器组件10。后挂组件30连接于两个耳挂组件20背离各自对应的扬声器组件10的另一端之间。在一些实施例中，声学装置1还可以包括一个或者多个拾音组件40。
扬声器组件10用于将音频转化成不同频率的机械振动。声学装置1在被佩戴时，扬声器组件10可以贴近使用者邻近耳朵的头部，进而可以通过头部的骨头将机械振动传递至人的听觉系统。耳挂组件20用于挂设于使用者的耳部。在一些实施例中，两个耳挂组件20可以分别设置有电池组件50和控制电路组件60，控制电路组件60可以用于控制整个声学装置1的操作，比如控制音量增减、控制开机/关机、控制耳机模式选择、控制无线连接或者数据传输等操作。电池组件50可以用于给整个声学装置1供电。
在声学装置1被佩戴时，后挂组件30可以绕设在使用者的头部的后侧。后挂组件30连接于两个耳挂组件20的另一端之间，结构可靠稳定，以使得声学装置1被稳定佩戴。
在一些实施例中，后挂组件30可以呈杆状。在一些实施例中，后挂组件30可以呈圆弧杆状，以与使用者的头部形状匹配。在一些实施例中，后挂组件30可以绕过使用者的头顶部或头后部。在一些实施例中，后挂组件30可以包括伸缩结构，以便于使用者调节后挂组件30的长度，以使得使用者拥有舒适的佩戴体验。
拾音组件40可以设置在声学装置的多个位置。在一些实施例中，拾音组件40可以设置在扬声器组件10上。在一些实施例中，拾音组件40可以设置在耳挂组件20上。在一些实施例中，拾音组件40可以设置在后挂组件30上。在一些实施例中，拾音组件40设于耳挂组件20的远离扬声器组件10的一端。将拾音组件40设于耳挂组件20的远离扬声器组件10的一端可以改善拾音组件40的“啸叫”情况，具体请参见下文的相关说明。
以声学装置1包括多个拾音组件40为例进行说明。在一些实施例中，多个拾音组件40可以设置于两个扬声组件10以及后挂组件30中的至少两者上。在另一些实施例中，多个拾音组件40可以间隔设置于后挂组件30上。其中，多个拾音组件40之间相互间隔设置且各自独立，以能够各自独立进行拾音和信号放大。需要说明的是：本实施例所述的“多个”是指“至少两个”，例如“两个”、“三个”、“四个”等。
在一些实施例中，多个拾音组件40中的一者设置于后挂组件30，且可以设置 于后挂组件30的中间位置。在一些实施例中，后挂组件30的中间位置可以是杆状的后挂组件30的中点的位置。在一些实施例中，至少两个拾音组件40设置于后挂组件30上，且其中一个拾音组件40设置于后挂组件的中间位置(例如杆状的后挂组件30的中点的位置)，其余拾音组件40位于中间位置的一侧或者两侧，且至少两个拾音组件40间隔设置。在另一些实施例中，声学装置1包括三个拾音组件40，其中两个拾音组件40分别一一对应地设置于两个耳挂组件20上，另外一个拾音组件40设置于后挂组件30上。上述拾音组件40各自独立，能够各自独立地进行拾音和信号放大，进而能够独立地对不同方位的声音进行处理，能够使得听障者可以适应不同方位的声音，提高听障者的听觉效果。
在一些实施例中，多个拾音组件40可以在后挂组件30长度方向上间隔布置。在一些实施例中，任意相邻的两个拾音组件40之间的间隔距离可以相等。在另一些实施例中，任意相邻的两个拾音组件40之间的间隔距离可以不相等。
在一些实施例中，将骨传导技术应用于助听耳机上，扬声器组件10需要具备良好的传音效果，扬声器组件10主要是利用机械振动的形式传送音频信号。通常情况下，如果扬声器组件10内存在较大的空气振动，可能会影响扬声器组件10机械振动的传音效果，降低音质，进而影响到听障者的听觉效果。在一些实施例中，扬声器组件10可以参照下述本申请实施例的描述进行设置。在另一些实施例中，下述扬声器组件10还可以应用于其它类型的骨传导声学装置，并不限于本说明书所描述的声学装置1。
图2是根据本申请的一些实施例所示的声学装置的拆解结构示意图；图3是图1所示的声学装置沿A-A剖切线的一截面结构示意图；图4是图1所示的声学装置沿A-A剖切线的另一截面结构示意图；图5是图4所示的防护组件和上盖的拆解结构示意图；图6是图1所示的声学装置沿A-A剖切线的又一截面结构示意图。在一些实施例中，图2-6所述的声学装置可以为图1中的扬声器组件10的具体实施方式。
如图2至图6所示，在一些实施例中，声学装置200可以包括壳体11、扬声器12以及防护组件13。扬声器12可以是骨传导扬声器。防护组件13可以是具有网孔的网状结构。扬声器12可以容置于壳体11内。防护组件13可以支撑于壳体11上，进而可以用于保护扬声器12。
如图2所示，在一些实施例中，壳体11可以具有容置腔110和开口111。壳体11开设开口111的一侧，用于贴近使用者的头部。容置腔110用于容置扬声器12。部分扬声器12可以由开口111伸出到容置腔110外，以使得扬声器12所产生的机械振 动可以传递到使用者的头部。
在一些实施例中，壳体11的内壁上可以设置承台112。在一些实施例中，承台112可以是环状的。壳体11的内壁是指壳体11围成容置腔110的内壁。承台112可以邻近开口111设置。在一些实施例中，承台112可以用于支撑防护组件13。在一些实施例中，当防护组件13支撑于承台112上时，可以使得防护组件13遮蔽或者大致遮蔽开口111，进而可以保护扬声器12。在一些实施例中，防护组件13遮蔽开口可以理解为开口111被防护组件13遮盖住。
在一些实施例中，承台112还可以设置为其他形状。在一些实施例中，承台112可以包括设于内壁上的多个凸起结构。多个凸起结构可以沿着某一指定方向间隔设置。例如，当容置腔110呈圆柱状时，多个凸起结构可以沿着圆柱的周向间隔设置，以形成非连续性的环形承台。
在一些实施例中，扬声器12可以包括振动组件121和传振板122。在一些实施例中，振动组件121可以包括音圈以及磁路组件(图中未示出)。在一些实施例中，振动组件121中的至少部分元件可以容置于容置腔110内。例如，振动组件121的振动片可以设置于容置腔110内。传振板122与振动组件121连接，并经开口111裸露。在一些实施例中，传振板122经开口111裸露可以是指传振板122经开口111而伸出到容置腔110外。扬声器12整体上可以形成自壳体11内凸出壳体11外的效果，传振板122从开口111伸出容置腔110外进而裸露。振动组件121在接收到音频信号时，可以将音频信号转化成机械振动并通过传振板122可以将扬声器12的振动经使用者的骨骼(例如，头骨)传递至人的听觉神经。
在一些实施例中，扬声器12可以完全位于容置腔110内。在一些实施例中，传振板122可以与开口111的位置相平齐。在一些实施例中，振动组件121可以经开口111而伸出到容置腔110外。
在一些实施例中，防护组件13设置于壳体11的开口端，并贴合传振板122。例如，防护组件13可以贴合传振板122的远离振动组件121的一端。在一些实施例中，如图3-4所示，防护组件13可以包括贴合部131(即防护组件1108的第一部分)、环壁部132以及支撑部133(环壁部132和支撑部133即为防护组件1108的第二部分)。在一些实施例中，支撑部133可以为环状。在一些实施例中，贴合部131和环壁部132可以形成筒状的容置部。在一些实施例中，传振板122可以设置于筒状的容置部内。贴合部131连接在环壁部132的一端，以用于封堵筒状的容置部的一端并与传振板122的 外端面(远离振动组件121的一端的表面)贴合设置。具体地，筒状容置部的一端可以是指筒状容置部远离容置腔110的一端，筒状容置部的另一端可以是指筒状容置部靠近容置腔110的一端。传振板122的外端面是指背离容置腔110的端面，或者远离振动组件121的端面。在具体装配过程中，可以将防护组件13盖合开口111，传振板122可以伸入到筒状容置部内，进而传振板122的外端面与贴合部131进行贴合。支撑部133可以连接于环壁部132的另一端，并向环壁部132的外侧延伸。支撑部133用于支撑于壳体11的开口端上。在一些实施例中，支撑部133可以支撑于承台112(如环状的承台)上。在一些实施例中，支撑部133和承台112之间可以设有胶粘层，以将支撑部133和承台112粘接起来。
通过设置连接振动组件121的传振板122经开口111伸出到容置腔110外，而且利用防护组件13贴合传振板122，能够使得传振板122更贴近使用者的头部，传振板122的振动能够更快速、更有力地传递给使用者的骨头。本申请实施例的机械振动更为完整、不容易丢失频段，能够有效地改善听障者的听觉效果。并且，由于防护组件13具有网状结构，能够使得容置腔110内外的空气在上述机械振动过程中相互流通，以平衡容置腔110内外的空气压差，进而减少容置腔110内的空气由于振动而产生的声音，衰减传振板122的机械振动之外的空气振动产生声音，进而可以减少漏音现象。相对于将容置腔110封闭的结构而言，防护组件13能够减少容置腔110内的空气振动对传振板122的振动带来的影响，进而有效提高声学装置200的音质和声音效果。
在一些实施例中，声学装置200可以包括上盖14，至少部分的支撑部133可以被夹持于上盖14和承台112之间，以使得防护组件13的支撑部133被压持于承台112上。从而使得支撑部133能够稳定地支撑于承台112上，以避免防护组件13掉落。在一些实施例中，上盖14可以呈环状。
在一些实施例中，支撑部133和上盖14之间可以设有胶粘层，以将支撑部133和上盖14粘接起来。
在一些实施例中，上盖14的形状可以与承台112的形状相一致。例如，当承台112为环状时，上盖14也为环状。又例如，当承台112包括多个凸起结构时，上盖14可以包括多个凸台。当上盖14将第二部分压持于承台112上时，多个凸台可以一一对应地设置在多个凸起结构的上方，或者，多个凸台与多个凸起机构可以交错布置。
对于上盖14、支撑部133以及承台112之间的位置关系，可以有如下几种实施方式：
在一些实施例中，如图3所示，支撑部133可以夹持于上盖14和承台112之间，其中，支撑部133的外表面(或上表面)贴近上盖14，环状的支撑部133的内表面(或下表面)贴近承台112。如本文中所述，防护组件13的内表面是指与传振板122的远离振动组件121的端面贴合的表面。支撑部133的内表面是指防护组件13的内表面在环状的支撑部133的部分。相应地，与防护组件13的内表面相背设置的是防护组件13的外表面。支撑部133的外表面是指防护组件13的外表面在环状的支撑部133的部分。在一些实施例中，上盖14直接压持支撑部133的外表面，进而将支撑部133的内表面压持在环状的承台112上。换言之，支撑部133从环状的上盖14和承台112之间的间隙的内侧往外侧延伸。图3中示出了图中1中的部分结构，未示出振动组件121。
在一些实施例中，支撑部133的内表面和承台112之间可以设置有胶粘层，进而将支撑部133和承台112进行直接或者间接粘接固定。传振板122的外端面和贴合部131之间也可以设置胶粘层，进而将传振板122和贴合部131粘接固定。在实际装配过程中，防护组件13可以通过胶水同时与传振板122、壳体11直接或间接粘接在一起，进而形成上述的胶粘层，接着再将上盖14盖在支撑部133上。当然，支撑部133的外表面和上盖14之间也可以设置有胶粘层，进而使得支撑部133和上盖14粘接固定。
通过上述图3中所述实施例对防护组件13进行固定，使得扬声器12的结构简单，装配方便，对防护组件13的支撑也较为稳定。
在一些实施例中，如图6所示，支撑部133的内表面可以包覆上盖14的边缘部分，且支撑部133可以弯折延伸至上盖14(如环状的上盖)和承台112(如环状的承台)之间，支撑部133的外表面贴近承台112。在一些实施例中，支撑部133内表面包覆上盖14的边缘部分，进而支撑部133可以从上盖14和承台112之间的间隙由外侧往内侧延伸。图6中示出了图中1中的部分结构，未示出振动组件121。
在一些实施例中，如图5以及6所示，支撑部133可以包括环状子部1331(即延伸部的部分区域)和弯折子部1332(即弯折部)。环状子部1331可以连接环壁部132，并往环壁部132的外侧延伸。弯折子部1332连接环状子部1331往环壁部132的外侧延伸的边缘，也即，弯折子部1332与环状子部1331往环壁部132的外侧延伸的边缘连接，并往远离环状子部1331的边缘的方向延伸。在一些实施例中，弯折子部1332的数量可以是多个，分别自环状子部1331的边缘往外延伸，弯折子部1332可以间隔设置于环状子部1331的边缘。在一些实施例中，弯折子部1332也可以是呈连续环状，自环状子部1331的边缘往外延伸。
在一些实施例中，环状子部1331可以包覆上盖14的边缘区域，且弯折子部1332自环状子部1331延伸至上盖14和承台112之间。支撑部133的内表面贴近上盖14。在一些实施例中，环状子部1331的内表面和弯折子部1332的内表面贴近上盖14。支撑部133的外表面贴近承台112。具体地，弯折子部1332的外表面贴近承台112。
在一些实施例中，支撑部133的外表面和承台112之间可以设置有胶粘层，进而将支撑部133和承台112进行粘接固定。传振板122的外端面和贴合部131之间也可以设置胶粘层，进而将传振板122和贴合部131粘接固定。在实际装配过程中，防护组件13可以先包覆上盖14，再通过胶水同时与传振板122、壳体11粘接在一起，进而形成上述的胶粘层。在一些实施例中，支撑部133的内表面和上盖14之间可以设置有胶粘层，进而使得支撑部133和上盖14粘接固定。
通过上述图6所述实施例对防护组件13进行固定，相较于图3中所述直接将支撑部133夹持在上盖14和承台112之间，通过支撑部133的内表面包裹上盖14，可以避免防护组件13和上盖14的内侧面(朝向容置腔110的侧面)之间形成的缝沟，进而在有效支撑支撑部133的基础上，可以避免灰尘在上述缝沟上堆积造成防护组件13的堵塞，减少声学装置的故障率。
在一些实施例中，如图4所示，上盖14可以包括层叠设置的第一盖体141和第二盖体142，第一盖体141相较于第二盖体142靠近承台112(如环状的承台)，第二盖体142支撑于承台112上。支撑部133可以夹持于第一盖体141和第二盖体142之间。在一些实施例中，支撑部133的内表面(如图4所示的下表面)贴近第一盖体141，支撑部133的外表面(如图4所示的上表面)贴近第二盖体142。图4中示出了图中1中部分结构，未示出振动组件121。
在一些实施例中，防护组件13可以和上盖14利用套啤技术，形成为一个整体。套啤技术所使用的套啤模具也叫包胶模具。在一些实施例中，套啤模具可以包括至少两套塑胶模具，先使用一套塑胶模具做好较硬的部分，然后将成型好的较硬的部分放入到另一套塑胶模具内注塑包裹。以防护组件13和上盖14利用套啤技术成型为例，上盖14的材料可以为硬胶，比如塑料，硬度大于防护组件13的硬度。先成型防护组件13，再将防护组件13放入到上盖14对应的模具中，再成型上盖14，进而形成第一盖体141和第二盖体142夹持防护组件13的支撑部133的结构。在另一些实施例中，防护组件13和上盖14之间的连接方式还可以是：支撑部133的内表面和第一盖体141之间可以设置有胶粘层(施加胶水，凝固后形成胶粘层)，进而使得支撑部133和第一盖体141 粘接固定。支撑部133的外表面和第二盖体142之间设置有胶粘层，进而将支撑部133和第二盖体142进行粘接固定。
将防护组件13和上盖14形成一个整体后，可以在第一盖体141和承台112(如环状的承台)之间设置胶粘层，进而将第一盖体141和承台112粘接固定。传振板122的外端面和贴合部131之间也可以设置胶粘层，进而将传振板122和贴合部131粘接固定。
在一些实施例中，支撑部133与第一盖体141之间，以及支撑部133与第二盖体142之间还可以通过卡接、螺纹连接等方式连接在一起。
在一些实施例中，支撑部133(如环状的支撑部)的内表面可以包覆第二盖体142的边缘部分，且支撑部133(如环状的支撑部)可以由包覆第二盖体142的边缘的位置朝向容置部弯折而延伸至第一盖体141和第二盖体142之间。
通过图4所述实施例设置上盖14包括第一盖体141和第二盖体142，第一盖体141和第二盖体142可以和防护组件13能够提前制作成一体，便于后期和壳体11进行装配，第一盖体141和第二盖体142的夹持(即防护组件13设于第一盖体141和第二盖体142之间，且防护组件13的两侧表面分别与第一盖体141和第二盖体142贴合)可以使得防护组件13的固定能够较为稳定。
在一些实施例中，如果将开口111封堵，比如利用硅胶包裹整个壳体11，会使得容置腔110内的空气也会振动进而产生声音，例如，会使得扬声器组件10在工作时在20-20000Hz内造成一个较大的固有频率谐振峰，导致漏音严重且可能会产生啸叫，降低扬声器12的扬声效果。
在一些实施例中，通过利用具有网孔结构的防护组件13，能够使得容置腔110内外的空气流通，而并非是将开口111封堵，可以有效降低谐振峰，进而有效地降低漏音现象。本申请的防护组件13具有多个网孔，多个网孔可以分布于防护组件13的部分位置，也可以遍布于整个防护组件13。例如，网孔可以设置在环壁部132上。又例如，网孔可以设置在贴合部131、环壁部132以及环状的支撑部133上，但由于网孔结构较密和细微，因此在图2-图8中并未具体示出网孔。
在一些实施例中，防护组件13的目数可以为250-600目在一些实施例中，防护组件13的目数为300-500目。在一些实施例中，防护组件13的目数为380-480目。在一些实施例中，防护组件13的目数为400-430目。。在一些实施例中，防护组件13的厚度可以为0.01mm-0.3mm。在一些实施例中，防护组件13的厚度为0.05mm-0.25mm。 在一些实施例中，防护组件13的厚度为0.1mm-0.2mm。一些实施例中，防护组件13的厚度为0.125mm-0.15mm。防护组件13的目数设计和厚度设计能够更加有效地降低漏音，而且能够保证防护组件13的强度。
在一些实施例中，防护组件13的材料可以是PC(聚碳酸酯)、PET(聚对苯二甲酸乙二醇酯)、尼龙中的至少一者。在一些实施例中，防护组件13的材料可以是金属材料或者合金材料，例如，钢、铝等。在一些实施例中，防护组件13的材料可以是纤维材料，例如，碳纤维、玻璃纤维等。
在一些实施例中，防护组件13可以通过热塑成型，进而可以使得防护组件13形成包括贴合部131、环壁部132以及环状的支撑部133的结构。具体地可利用如下实施例提高防护组件13成型的良品率和结构稳定性。
在一些实施例中，防护组件13可以通过3D打印的方式制造。
本申请的有益效果是：本申请将骨传导技术应用于助听设备，能够解决传统助听器的传统传音方式对听障者的听觉效果改善受限的问题，而且通过设置连接振动组件121的传振板122经开口111伸出到容置腔110外，而且利用防护组件12贴合传振板122，能够使得传振板122更直接地贴近使用者的头部，伸出容置腔110外的传振板122的振动能够更快速、更有力地传递到使用者的骨头，进而使得机械振动的传递更为完整、不容易丢失频段，能够有效地改善听障者的听觉效果。而且，由于防护组件13的网状结构，能够使得容置腔110内外的空气可以流通，进而减少容置腔110内的空气由于振动而产生的声音，使得由机械振动之外的空气振动所产生的声音衰减，可以有效减少漏音现象。此外，具有网状结构的防护组件13相对于将容置腔110封闭的结构而言，也能够减少容置腔110内的空气振动对传振板122的机械振动带来的影响，能够有效提高声学装置200的音质和助听效果。
本申请还提供一种用于制备声学装置的防护组件的生产方法。该方法包括以下步骤：
步骤S1，将网状结构(例如，纱网)与衬材贴合而形成组合体。其中，衬材的硬度大于网状结构的硬度。
步骤S2，利用成型技术将组合体进行成型，以获得成型后的组合体。在一些实施例中，成型技术可以包括热压成型技术、冲压成型技术、3D打印成型等。在一些实施例中，可以对组合体进行热压成型。在另一些实施例中，可以先将组合体进行热压成型，再将组合体进行冲压成型。在又一些实施例中，可以先将组合体进行冲压成型，再 将在将组合体进行热压成型。
步骤S3，基于成型后的组合体，获得防护组件。步骤S3中的成型后的组合体可以是先冲压成型再热压成型后的组合体，也可以是先热压成型再冲压成型后的组合体，还可以是直接热压成型后的组合体。在将成型后的组合体的衬材与网状结构分离后，获得成型后的网状结构(即防护组件)。成型后的网状结构可以构成具有第一部分和第二部分的防护组件。第二部分以及第一部分可以形成筒状结构。至少部分的第二部分可以形成筒状结构的筒壁(例如，环形筒壁，即环壁，例如，图3中的环壁部132)；第一部分可以形成筒状结构的底壁(例如，图3中的贴合部131)。第一部分以及第二部分可以形成容置部。在一些实施例中，第一部分可以大致垂直与第二部分。在一些实施例中，第二部分可以包括筒状结构的筒壁以及沿着与筒壁大致垂直的方向延伸的侧部(例如，图3中的支撑部133)。在一些实施例中，可以根据防护组件的使用需求进一步对网状结构进行加工，例如，在网状结构上加工出卡槽或螺纹孔等。
在一些实施例中，可以直接纱网进行热压成型而使得纱网可以形成具有第一部分和第二部分的防护组件。
本申请还提供一种纱网组件，本申请纱网组件实施例可以应用于上述本申请的声学装置的扬声器。图7是根据本申请的一些实施例所示的纱网组件的拆解结构示意图，图8是根据本申请的一些实施例所示的纱网组件的贴合状态的截面结构示意图，图9是根据本申请的一些实施例所示的纱网组件的一个制备流程的示意图。如图7所示，本实施例的纱网组件可以包括彼此贴合设置的防护组件13和衬材15。
在一些实施例中，如图7至图9所示，防护组件13(可以是指成型后的纱网)和衬材15(可以是成型后的衬材)可以通过纱网以及衬材进行热压成型后得到相应的结构。例如，防护组件13(可以是指成型后的纱网)包括贴合部131、环壁部132以及支撑部133，贴合部131用于封堵环壁部132的一端，支撑部133连接于环壁部132的另一端，并向环壁部132的外侧延伸。其中，衬材15的硬度大于防护组件13的硬度，并且衬材15与防护组件13在经过成型后的形状相同，进而可以支撑防护组件13保持热压后的形状。在一些实施例中，衬材15的材料可以为塑胶。
在一些实施例中，由于衬材15的硬度大于防护组件13的硬度，防护组件13和衬材15一同热压成型时，衬材15和防护组件13一同变形到相应的形状，此时两者共形设置，衬材15能够支撑防护组件13保持相应的形状。在装配时，将防护组件13装配至壳体11。
利用本实施例的上述方案对防护组件13进行成型，具体的制备方法可以参考图9以及图10中的详细描述。
图9是根据本申请的一些实施例所示的防护组件的一个制备流程900的示意图。
如图9所示，流程900包括如下操作。
S11：准备原始纱网13C和原始衬材15B，将两者彼此贴合；
S12：将彼此贴合的原始纱网13C和原始衬材15B进行冲压成型，获得预定大小的防护组件13和衬材15；
S13：将防护组件13和衬材15贴合后，进行热压成型，衬材15和防护组件13两者共形，以使得衬材15能够支撑防护组件13保持热压后的形状，其中，热压后的防护组件13可以包括贴合部131、环壁部132以及支撑部133，贴合部131用于封堵环壁部132的一端，支撑部133连接于环壁部132的另一端，并向环壁部132的外侧延伸；
S14：剥离衬材15，进而获得防护组件13。
图10是根据本申请的一些实施例所示的纱网组件另一制备流程1000的示意图。
如图10所示，流程1000包括如下操作。
S21：准备原始纱网13C和原始衬材15B；
S22：将彼此贴合的原始纱网13C和原始衬材15B进行热压成型，热压成型的原始纱网13C和原始衬材15B共形，以使得原始衬材15B能够支撑原始纱网13C保持热压后的形状；
S23：将热压成型后的原始纱网13C和原始衬材15B，进行冲压成型，进而得到共形设置的防护组件13和衬材15，其中，防护组件13包括贴合部131、环壁部132以及支撑部133，贴合部13A用于封堵环壁部132的一端，支撑部133连接于环壁部132的另一端，并向环壁部132的外侧延伸；
S24：剥离衬材15，进而获得防护组件13。
本实施例通过利用衬材15辅助防护组件13进行热压成型，由于衬材15的硬度比防护组件13的硬度大，进而再热压后，衬材15能够支撑防护组件13保持热压后的形状，进而能够获得形状和结构稳定的防护组件13，提高防护组件13的良品率和结构稳定性，便于后续进行装配至相应的壳体11内，而且由于防护组件13能够有效地保持其热压后的形状，能够和扬声器12的结构、形状相适应，能够有效地贴合传振板122的外端面，防护组件13稳定的网状结构，能够使得容置腔110内外的空气可以流通，进而减少容置腔110内的空气由于振动而产生的声音，衰减传振板122的机械振动之外 的空气振动产生声音，进而可以减少漏音现象，防护组件13相对于将容置腔110封闭的结构而言减少扬声器组件10的漏音。
本实施例的纱网组件能够提高防护组件13的结构稳定性，有助于提升声学装置200的助听效果。
