Description

一种扬声器模组 技术领域
本发明涉及电声产品技术领域。更具体地，涉及一种扬声器模组。
背景技术
扬声器模组是便携式电子设备的重要声学部件，用于完成电信号与声音信号之间的转换，是一种能量转换器件。现有的扬声器模组包括外壳和收容在外壳内的扬声器单体，扬声器单体将整个模组内腔分隔为前腔和后腔两个腔体，前腔连通扬声器模组的外界。在扬声器单体工作的过程中会产生大量的热量，会使后腔内的气体膨胀气压升高，从而导致前腔与后腔内的气压不平衡，致使振膜上下振幅不对称，影响扬声器单体的正常工作。为了平衡前腔与后腔内的气压，保持振膜振动的振幅对称性，就需要在构成后腔的外壳上开一个泄漏孔，保障后腔与外界连通，从而保持前腔与后腔内的气压平衡。由于泄漏孔自身的泄漏量较大，需要额外粘贴带有声阻特性的阻尼膜调整泄漏量，以满足扬声器模组的声学性能要求，常用的阻尼膜为网布、透声膜或无纺布中的一种。
在扬声器单体工作的过程中，当后腔内的气体膨胀气压升高后，气体会由泄漏孔透过阻尼膜向外界流动。气体向外界的流动过程决定了后腔气压的变化过程，也就决定了振膜振动的振幅对称性，其中气体向外界的流动过程例如气体由泄漏孔透过阻尼膜向外界直接流动或气体由泄漏孔透过阻尼膜向外界流动的过程中出现涡流或驻波现象等等。而在目前的扬声器模组中，如果泄漏孔的规格参数是确定的，气体向的外界流动过程只能为气体由泄漏孔透过阻尼膜向外界直接流动，无法通过改变气体向的外界流动过程进一步改善振膜振动的振幅对称性。
因此，需要提供一种新的扬声器模组以克服上述现有技术中存在的缺陷。
发明内容
本发明的目的在于提供一种扬声器模组，以改变气体由泄漏孔向外界流动的过程，进而进一步改善振膜振动的振幅对称性。
本发明采用下述技术方案：
为达到本发明的目的，本发明公开了一种扬声器模组，包括外壳，所述外壳内收容有扬声器单体，所述扬声器单体将模组内腔分隔成前腔和后腔，所述外壳上对应所述后腔的位置设有泄漏孔，位于所述泄漏孔周边的所述外壳的外侧表面上固定有覆盖所述泄漏孔的阻尼件，
所述阻尼件包括通过第一胶层粘接在一起的透声的阻尼膜和支撑件，所述支撑件具有第一内孔且环设于所述阻尼膜的边缘，所述第一胶层具有第二内孔且环设于所述支撑件的外侧边缘，所述阻尼膜的远离所述支撑件的一侧边缘通过第二胶层粘贴于所述外壳的外侧表面，所述第二胶层具有第三内孔；
其中，所述第一内孔的孔径小于所述第二内孔的孔径，所述支撑件的内侧边缘与所述阻尼膜之间形成缓冲腔。
优选地，所述第一内孔的孔径小于等于所述泄漏孔的孔径。

优选地，所述第一胶层和所述第二胶层均为双面胶，所述第一胶层的厚度大于等于0.05mm。
优选地，所述支撑件的材质为金属或硬质塑料。
优选地，所述硬质塑料为PET、PC、PP或ABS。
优选地，所述阻尼膜为网布或透声膜。
优选地，所述网布为无纺布。
本发明的有益效果如下：
本发明所述技术方案可改变气体由泄漏孔向外界流动的过程，即使得气体由泄漏孔向外界流动的过程中在延缓空气流通的空间中形成反射、涡流、谐振和驻波现象中的一种或多种，从而可进一步改善振膜振动的振幅对称性。
附图说明
下面结合附图对本发明的具体实施方式作进一步详细的说明；
图1示出扬声器模组的装配结构图。
图2示出扬声器模组的局部剖视图。
具体实施方式
为了更清楚地说明本发明，下面结合优选实施例和附图对本发明做进一步的说明。附图中相似的部件以相同的附图标记进行表示。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本发明的保护范围。
如图1和图2共同所示，本实施例提供的扬声器模组，包括外壳10，外壳10内收容有扬声器单体20，扬声器单体20将模组内腔分隔成前腔和后腔，外壳10上对应后腔的位置设有泄漏孔，位于泄漏孔周边的外壳10上固定有覆盖泄漏孔的阻尼件30，阻尼件30包括通过第一胶层301粘接在一起的透声的阻尼膜302和支撑件303，支撑件303具有第一内孔且环设于阻尼膜302的边缘，第一胶层301具有第二内孔且环设于支撑件303的外侧边缘，阻尼膜302的远离支撑件303的一侧边缘通过第二胶层304粘贴于外壳10的外侧表面，第二胶层304具有第三内孔；其中，支撑件303的第一内孔的孔径小于第一胶层301的第二内孔的孔径，支撑件303的内侧边缘与阻尼膜302之间形成缓冲腔。缓冲腔即图2中支撑件303的内侧边缘、第一胶层301的内侧表面和阻尼膜302的上表面形成的腔体。缓冲腔的存在使得气体由泄漏孔向外界流动的过程中在缓冲腔中形成反射、涡流、谐振和驻波现象中的一种或多种，从而可进一步改善振膜振动的振幅对称性。另外，支撑件303还可起到定形的作用，能够有效的避免阻尼膜302在加工和使用的过程中出现褶皱，提升了外观的良性，且在粘接的时候能够有效的改善阻尼膜翘起的问题，不会出现漏气，粘接良率高。
在具体实施时，支撑件303的第一内孔的孔径小于等于泄漏孔的孔径。这样形成的缓冲腔使得气体由泄漏孔向外界流动的过程中在缓冲腔中形成反射、涡流、谐振和驻波现象中的一种或多种的效果更显著，对振膜振动的振幅对称性的改善更明显。
在具体实施时，支撑件303的第一内孔、第一胶层301的第二内孔、第二胶层304的第三内孔和泄漏孔同轴设置，即三个内孔和泄漏孔均同轴设置。这样形成的缓冲腔使得气体由泄漏孔向外界流动的过程中在缓冲腔中形成反射、涡流、谐振和驻波现象中的一种或多种的效果更显著，对振膜振动的振幅对称性的改善更明显，且阻尼件30更易制备。
在具体实施时，第二胶层304的第三内孔的孔径大于泄漏孔的孔径。这样形成的缓冲腔使得气体由泄漏孔向外界流动的过程中在缓冲腔中形成反射、 涡流、谐振和驻波现象中的一种或多种的效果更显著，对振膜振动的振幅对称性的改善更明显。
在具体实施时，第一胶层301的第二内孔和第二胶层304的第三内孔的孔径可以相同，阻尼件30更易制备。但是不限定必须相同，根据实际情况选择，可以不同。
在具体实施时，第一胶层301和第二胶层304均为双面胶，第一胶层301的厚度大于等于0.05mm。基于外壳10通常的厚度和泄漏孔通常的孔径，第一胶层301的厚度大于等于0.05mm可形成有效的缓冲腔。
在具体实施时，支撑件303的材质为金属或硬质塑料，硬质塑料为PET(聚对苯二甲酸乙二醇酯)、PC(聚碳酸酯)、PP(聚丙烯)或ABS(丙烯腈-丁二烯-苯乙烯)中的一种，但并不限定为上述的几种，只要具有一定刚性的材料均可。上述对支撑件303的材料的选择使其具有更大的刚性。一方面，支撑件303参与形成缓冲腔，在气体流动过程中受力较大，具有更大的刚性的支撑件303不易变形或损坏；另一方面，具有更大的刚性的支撑件303可对阻尼膜302起到更好的定形的作用。
在具体实施时，阻尼膜302可为网布或透声膜或无纺布，网布或透声膜均具有良好的透声性。进一步网布可为无纺布，即阻尼膜302可为无纺布。
在本发明的描述中，需要说明的是，术语“上”、“下”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
还需要说明的是，在本发明的描述中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或 者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动，这里无法对所有的实施方式予以穷举，凡是属于本发明的技术方案所引伸出的显而易见的变化或变动仍处于本发明的保护范围之列。
