请参阅图1至图2，图1是本申请实施例提供的聆听设备10的分解结构示意图，图2是图1中壳体100、扬声器200、隔离架300以及支架400的装配结构示意图。
本申请实施例提供的聆听设备10可以是无线耳机、有线耳机以及音箱等具有声音播放功能的设备，下面仅以聆听设备10以无线耳机为例进行说明。如图1所示，聆听设备10可以包括：壳体100、扬声器200、隔离架300以及支架400。其中，扬声器200、隔离架300以及支架400均设置于壳体100内。隔离架300可以位于扬声器200的一侧，且隔离架300可以用于形成聆听设备10声腔的腔壁。支架400可以分别连接壳体100和扬声器200，且支架400也可以用于形成聆听设备10声腔的腔壁。
具体地，壳体100除了可以用于安装扬声器200、隔离架300以及支架400外，还可以用于安装聆听设备10所需的其他功能件。如图1至图2所示，壳体100可以设置有空腔101以及与空腔101相连通的出声孔102。其中，空腔101可用于容纳扬声器200、隔离架300、支架400以及聆听设备10所需的其他功能件。出声孔102可以用于将扬声器200发出的声音传导至空腔101外，以实现聆听设备10的声音播放功能。同时，壳体100的材质可以塑料，以减轻聆听设备10的重量，且壳体100的形状可以与用户的耳道形状相适配，以提高用户佩戴聆听设备10的舒适度。此外，壳体100的外表面还可以设置有功能涂层，用于提高壳体100的耐磨耐腐蚀性。
为了实现壳体100与扬声器200、隔离架300以及支架400等功能件的装配，壳体100还可以拆件为前壳110和后壳120。其中，前壳110和后壳120可以共同围设形成前述的空腔101，且前壳110可以开设有前述的出声孔102。同时，前壳110和后壳120两者可以通过如卡接、粘 接、焊接以及熔接等方式固定连接。
扬声器200可以用于将电信号转换为声信号，以实现聆听设备10的声音播放功能。如图2所示，扬声器200可以设置于空腔101内，并与空腔101的腔壁间隔设置。同时，扬声器200的发声面201可以位于扬声器200朝向出声孔102的一面上，并与出声孔102相对设置。其中，扬声器200具体可以是动圈式扬声器、动铁式扬声器以及平面振膜式扬声器中的任意一种。
本申请实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
请结合图2参阅图3，图3是一些聆听设备10的截面结构示意图。
经发明人长期研究发现，一些聆听设备10的前后声腔主要通过扬声器200进行划分。如图3所示，扬声器200可以将空腔101划分为前声腔1011和后声腔1012。然而，采用此种方案形成的后声腔1012内一般还需装配聆听设备10的功能件，如电池或电路板等等，这会导致后声腔1012受到功能件的加工精度和装配精度的影响，进而影响聆听设备10的音质。为此，本实施例的聆听设备10可以设置有用于保持后声腔1012独立性的隔离架300，以改善聆听设备10的声学表现力。
如图2所示，隔离架300可以位于背离扬声器200背离其发声面201的一侧，也即是扬声器200远离出声孔102的一侧，且隔离架300可以与空腔101的腔壁连接，其可以用于将空腔101分隔为两个相独立的腔室。例如，隔离架300背离后声腔1012的一侧可以与壳体100，也即是空腔101的腔壁共同围设形成容纳腔301，且该容纳腔301可以用于安装聆听设备10的功能件，而隔离架300朝向扬声器200的一侧则可以用于形成后声腔1012的腔壁。如此设置，可以通过隔离架300将后声腔1012和容纳腔301分隔开来，以保持两者的独立性，降低聆听设备10的功能件对后声腔1012的影响，改善聆听设备10的声学表现力。
隔离架300还可以用于装配扬声器200，使得扬声器200可以通过隔离架300固定在空腔101内。例如，扬声器200可以设置于隔离架300背离容纳腔301的一侧上，两者可以通过如粘接、焊接以及螺钉连接等方式固定连接。同时，隔离架300上还可以设置有避让结构，如避让槽或避让孔等，扬声器200则可以设置于避让槽或避让孔内，以减少扬声器200和隔离架300的堆叠高度。此外，隔离架300与空腔101的腔壁之间的连接面上还可以设置有密封件500，如密封胶、泡棉、硅胶以及橡胶等等，以提高后声腔1012的密封性。
可选地，隔离架300上的避让孔或避让槽还可以贯穿隔离架300，以进一步减少扬声器200和隔离架300的堆叠高度，而扬声器200则可以用于封堵避让槽或避让孔，并与隔离架300背离后声腔1012的一侧以及壳体100共同围设形成前述的容纳腔301，即扬声器200也可以用于形成容纳腔301的腔壁。相应地，隔离架300与扬声器200之间的连接面上也可以设置有前述的密封件500，以提高后声腔1012的密封性。
进一步地，由于隔离架300是将部分后声腔1012分隔出去形成容纳腔301，因此隔离架300的设计会导致后声腔1012的体积大幅度减小(如图2和图3所示)，而体积较小的后声腔1012不利于提升聆听设备10的音质。为此，本实施例提供的聆听设备10可以设置有用于扩大后声 腔1012的支架400，以提高聆听设备10的音质。如图2所示，支架400可以设置于空腔101内，且支架400可以位于发声面201靠近出声孔102的一侧。同时，支架400可以分别与壳体100，也即是空腔101的腔壁和扬声器200连接，且支架400还可以围设形成连通发声面201和出声孔102的通孔401。其中，支架400朝向通孔401的内侧壁402可以用于形成聆听设备10的前声腔1011的腔壁，而支架400背离通孔401的外侧壁403可以用于形成聆听设备10的后声腔1012的腔壁。
如图2和图3所示，本实施例提供的支架400可以将前声腔1011的部分体积划分给后声腔1012，使得后声腔1012可以由发声面201背离出声孔102的一侧扩展至发声面201朝向出声孔102的一侧，以在增加后声腔1012的体积的同时，减少前声腔1011的体积。如此，不仅可以利用较大的后声腔1012提升扬声器200发出声音的低频弹性和下潜特征，还可以利用较小的前声腔1011拓宽扬声器200发出声音的中高频延展，从而提升聆听设备10的音质。
具体地，内侧壁402可以与扬声器200共同围设形成聆听设备10的前声腔1011。例如，通孔401远离发声面201的开口孔径可以等于出声孔102靠近发声面201的开口孔径，且通孔401和出声孔102可以刚好相对准。如此，空腔101的腔壁(壳体100)可以不构成前声腔1011的腔壁，这样设计可以进一步减少前声腔1011的体积。
可选地，内侧壁402也可以与壳体100和扬声器200共同围设形成聆听设备10的前声腔1011。例如，通孔401远离发声面201的开口孔径可以大于出声孔102靠近发声面201的开口孔径，且通孔401和出声孔102也可以相对准。如此，空腔101的腔壁也可以构成前声腔1011的腔壁，且开口孔径较大的通孔401更有利于与出声孔102进行对准装配。
外侧壁403可以与壳体100、扬声器200以及隔离架300共同围设形成后声腔1012。例如，扬声器200和外侧壁403均可以与空腔101的腔壁间隔设置，使得空腔101的腔壁、扬声器200、外侧壁403以及隔离架300可以共同围设形成后声腔1012。其中，外侧壁403的部分区域还可以在朝向内侧壁402的方向上凹陷设置，以形成避让空间进一步扩大后声腔1012的体积。同时，为了保持后声腔1012内与聆听设备10外的气压平衡，壳体100用于形成后声腔1012腔壁的区域还可以开设有泄压孔103。进一步地，泄压孔103还可以通过防水透气胶或防水透气膜覆盖，以降低后声腔1012进入水渍或灰尘的概率。相较于仅利用扬声器200、隔离架300以及空腔101的腔壁共同围设形成后声腔1012的方案，支架400可以将后声腔1012扩展至发声面201朝向出声孔102的一侧，以增加后声腔1012的体积。
如图2所示，支架400还可以具有分别与内侧壁402和外侧壁403连接并相对设置的底壁404和顶壁405。其中，底壁404可以与扬声器200朝向出声孔102的一侧连接，并围绕发声面201设置。顶壁405可以与空腔101的腔壁连接，并围绕出声孔102朝向扬声器200的开口设置。如此，支架400可以分别连接壳体100和扬声器200，并围设形成连通发声面201和出声孔102的通孔401。优选地，底壁404和顶壁405可以相平行。
进一步地，为了提高后声腔1012的密封性，顶壁405和空腔101的腔壁之间也可以设置有密封件500，以利用密封件500填补顶壁405和空腔101的腔壁之间的装配间隙。其中，当密封件500为密封胶时，其还可以起到粘接壳体100和支架400的作用，以提高支架400和壳体100的装配牢固性。当密封件500为泡棉、硅胶或者橡胶时，密封件500可以分别与支架400的顶壁405和空腔101的腔壁相抵接，以提高支架400和壳体100的密封可靠性。同时，为了避免密封件500在抵压过程中发生偏移，顶壁405或者空腔101的腔壁上还可以开设有容纳密封件 500的限位槽，而密封件500可以通过限位槽嵌设在顶壁405或者空腔101的腔壁上，以利用限位槽限制密封件500在抵压过程中的位置，避免密封件500发生偏移。
为了进一步提升聆听设备10的音质，聆听设备10还可以设置有用于调整声阻的调音件600，支架400还可以开设有连通前声腔1011和后声腔1012的声短路孔406。如图2所示，声短路孔406贯穿内侧壁402和外侧壁403，以连通前声腔1011和后声腔1012。调音件600可以贴附在外侧壁403上，并覆盖声短路孔406。其中，调音件600可以是调音棉或网布，其可以具有透气性，使得聆听设备10可通过调音件600控制前声腔1011和后声腔1012的透气量，以达到调音的目的。可选地，调音件600也可以贴附在内侧壁402上，或者是直接设置于声短路孔406内，仅需调音件600能够控制声短路孔406的透气量即可，本实施例对此不作限定。
请参阅图4至图6，图4是图1中壳体100、扬声器200、隔离架300以及支架400的另一装配结构示意图，图5是图1中壳体100、扬声器200、隔离架300以及支架400的又一装配结构示意图，图6是图1中壳体100、扬声器200、隔离架300以及支架400的还一装配结构示意图。
可选地，外侧壁403也可以仅与扬声器200和隔离架300共同围设形成后声腔1012。如图4所示，聆听设备10可以设置有位于空腔101内，并分别与隔离架300和支架400的外侧壁403连接的连接架700。其中，连接架700可以与空腔101的腔壁相贴合，并围绕外侧壁403设置。如此，连接架700可以代替空腔101的腔壁，与外侧壁403、扬声器200以及隔离架300共同围设形成后声腔1012。在本实施例中，连接架700和隔离架300可以是一体结构，两者可以通过注塑成型等工艺一体成型。
可选地，为了便于支架400和壳体100进行定位装配，空腔101的腔壁上还可以设置有定位部104。如图5所示，定位部104可以围绕出声孔102设置，支架400可以位于定位部104背离出声孔102的一侧，且支架400可以围绕定位部104设置。同时，内侧壁402上还可以开设有用于容纳定位部104的凹槽，且该凹槽可以贯穿支架400的顶壁405。如此，在装配支架400和壳体100时，可以利用定位部104进行定位装配，提高支架400和壳体100装配便利性。
可选地，除了通过定位部104实现定位装配的方案，空腔101的腔壁上也可以通过开设容纳支架400的环形槽，来实现支架400与壳体100的定位装配。例如，环形槽可以围绕出声孔102设置，并与出声孔102相连通，支架400则可以设置于环形槽内。如此，在装配支架400和壳体100时，支架400可以利用环形槽定位装配在空腔101的腔壁上，以提高支架400和壳体100的装配便利性。
可选地，扬声器200除了可以通过隔离架300固定在空腔101内，其也可以通过支架400固定在空腔101内。如图6所示，扬声器200可以与支架400的底壁404连接，两者可以通过如粘接、焊接以及螺钉连接的方式固定连接。同时，扬声器200的位置还可以向靠近出声孔102的方向位移，以与隔离架300间隔设置，从而扩大后声腔1012的体积，减小前声腔1011的体积，提高聆听设备10的音质。此外，由于扬声器200通过支架400固定在空腔101内，因此密封件500可以为密封胶，以提高支架400和壳体100的连接牢固性。
可选地，扬声器200也可以与空腔101的腔壁连接，以固定在空腔101内。其中，为了使得扬声器200靠近出声孔102一侧的空间与扬声器200远离出声孔102一侧的空间相连通以形成后声腔1012，扬声器200的周侧至少有部分区域可以与空腔101的腔壁间隔设置。此外，由于扬声器200可以与空腔101的腔壁连接进行固定，因此密封件500则可以为密封胶、硅胶、 橡胶以及泡棉中的任意一种，本实施例对此不作限定。
请参阅图7，图7是图1中扬声器200的另一结构示意图。
可选地，为了提高空腔101内的空间利用率，支架400也可以是构成扬声器200的一部分，下面仅以扬声器200为动圈式进行举例说明。如图7所示，扬声器200可以包括：安装壳210、振膜组件220以及支架400。其中，安装壳210可以具有安装槽(图未示出)，振膜组件220可以设置于安装槽内，且振膜组件220可以在通电后产生振动以发出声音。支架400可以代替扬声器200原本的前罩与安装壳210连接，并盖设在安装槽上，其围设形成的通孔401则可以连通振膜组件220和出声孔102，使得振膜组件220发出的声音能够从通孔401传导至出声孔102处。如此，可以省略扬声器200原有的前罩设计，不仅可以减少扬声器200和支架400的堆叠高度，提高空腔101内的空间利用率，还可以节约聆听设备10的生产成本。
具体地，振膜组件220可以包括：振膜221、华司222、永磁体223以及音圈224。其中，振膜221可以与安装壳210连接，且振膜221可以盖设在安装槽上，并与安装壳210共同围设形成与后声腔1012连通的内腔202，其可以用于振动发声。例如，安装壳210上可以开设有通孔，以连通内腔202和后声腔1012。华司222位于内腔202内，并与振膜221间隔设置，以预留出振膜221的振动空间。永磁体223设置于华司222背离振膜221的一侧，且永磁体223还可以与安装壳210位于内腔202的侧壁间隔设置。音圈224可以设置于永磁体223和安装壳210位于内腔202的侧壁之间，并与振膜221连接。当音圈224通电产生磁力时，可以与永磁体223的磁力相作用而发生位移，从而带动振膜221运动。由此，可通过控制音圈224的磁力大小和通电时间，来带动振膜221振动发声。动圈式扬声器的具体结构及发声原理可参现有技术，本实施例在此不予赘述。
本申请实施例提供的聆听设备10，通过在壳体100和扬声器200之间设置支架400，且支架400围设有连通扬声器200和壳体100出声孔102的通孔401，以及聆听设备10的后声腔1012的腔壁可以包括支架400背离通孔401的外侧壁403以及位于背离扬声器200发声面201一侧的隔离架300，使得后声腔1012可以扩展至发声面201朝向出声孔102的一侧，以增加后声腔1012的体积，有利于提升聆听设备10的音质。
以上所述仅为本申请的部分实施例，并非因此限制本申请的保护范围，凡是利用本申请说明书及附图内容所作的等效装置或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
