Description

扬声器箱 技术领域
本申请涉及声电技术领域，尤其涉及一种扬声器箱。
 背景技术
随着智能移动终端的广泛应用，用于播放声音的扬声器箱也被大量应用。扬声器箱在工作时，其内部产生大量的热量，会使后腔内的气体膨胀气压升高，从而导致前腔和后腔内的气压不平衡，影响扬声器箱的正常工作，为了使扬声器箱能正常工作，通常需在与后腔对应的壳体上开设泄漏孔，并配置封盖泄漏孔的透气隔离件。另外，为了使扬声器箱获得更好的音频效果，在扬声器箱的后腔部分会填充吸音颗粒，相应地在与后腔对应的壳体上也会开设用于灌入吸音颗粒的灌粉孔，并配置用于封盖灌粉孔的盖板。所以，现有的扬声器箱既需要开设泄漏孔又需要开设灌粉孔，并且要配置封盖泄漏孔的透气隔离件和封盖灌粉孔的盖板，结构复杂，工艺流程繁琐。请参阅图1，扬声器箱100'的壳体1'上分别设有泄漏孔121和灌粉孔122，同时为泄漏孔121配置了透气隔离件31'，为灌粉孔122配置了盖板32'。
因此，有必要提供一种既可以平衡后腔与前腔之间的气压又可以灌入吸音颗粒且结构简单的扬声器箱。
 技术问题
本申请的目的在于提供一种扬声器箱，以解决现有的扬声器箱既要开设泄漏孔又要开设灌粉孔的技术问题。
 技术解决方案
本申请的目的提供的技术方案如下：扬声器箱，包括壳体、安装于所述壳体内的发声单体以及固设于所述壳体外的遮盖组件，所述壳体设有容置腔和通孔，所述发声单体固设于所述容置腔内并将所述容置腔分隔为前腔和后腔，所述通孔与所述后腔连通；
所述遮盖组件包括透气隔离件和盖板，所述透气隔离件遮盖所述通孔且固定于所述盖板上，所述盖板与所述壳体连接并设于所述透气隔离件之远离所述通孔的一侧，所述盖板设有盖孔，所述后腔中的气体依次流过所述通孔、所述透气隔离件和所述盖孔流到所述壳体之外。
进一步地，所述遮盖组件还包括第一粘接件，所述透气隔离件通过所述第一粘接件固定于所述盖板上。
进一步地，所述第一粘接件具有第一内孔，所述第一内孔的孔径大于或等于所述盖孔的孔径。
进一步地，所述遮盖组件还包括第二粘接件，所述盖板通过所述第二粘接件固定于所述壳体上。
进一步地，所述第二粘接件具有第二内孔，所述透气隔离件和所述第一粘接件均容置于所述第二内孔中。
进一步地，所述第二内孔的孔径大于所述通孔的孔径。
进一步地，所述盖孔、所述第一内孔、所述第二内孔以及所述通孔同轴设置。
进一步地，所述透气隔离件为无纺布、尼龙编织网、羊毛编织网、金属网以及调音纸中的任意一种。
进一步地，所述盖板为包括聚对苯二甲酸乙二醇酯、聚碳酸酯、聚丙烯或丙烯腈-丁二烯-苯乙烯中任意一种材质的面板。

 有益效果
本申请的有益效果在于：通过在与后腔对应的壳体上设置与后腔连通的通孔，在后腔与前腔的气压不平衡时，后腔可以通过通孔泄压，以保证扬声器箱的正常工作，并且吸音颗粒可以从通孔处灌入后腔中，所以，通过设置一个通孔，既可以平衡后腔与前腔之间的气压又可以灌入吸音颗粒，减少了通孔的设置数量，简化了制作工艺。通过设置透气隔离件遮盖通孔，空气中的灰尘等杂质不能通过通孔进入后腔中，而后腔中的气体可以透过透气隔离件流到壳体之外。通过设盖板，可将透气隔离件通过盖板固定在壳体上，通过在盖板上设置盖孔，有利于后腔中的气体通过透气隔离件流出。因此，本申请提供的扬声器箱既可以平衡后腔与前腔之间的气压又可以灌入吸音颗粒，并且结构简单、制造工艺简洁、制造成本低。

 本发明的实施方式
下面结合图2至图5对本申请作详细描述。
请参阅图2至图5，本申请实施例提供一种扬声器箱100，包括壳体1、安装于壳体1内的发声单体2以及固设于壳体1外的遮盖组件3，壳体1设有容置腔11和通孔12，发声单体2固设于容置腔11内并将容置腔11分隔为前腔111和后腔112，通孔12与后腔112连通以用于向后腔112内灌入吸音颗粒和用于释放后腔112中的气体以平衡后腔112与前腔111之间的气压，遮盖组件3安装于通孔12处并遮盖通孔12。通过在与后腔112对应的壳体1上设置与后腔112连通以用于向后腔112内灌入吸音颗粒和用于释放后腔112中的气体以平衡后腔112与前腔111之间的气压的通孔12，可以将吸音颗粒从通孔12处灌入后腔112中以改善扬声器箱100的声学性能，而且，在当扬声器单体工作产生的热量导致后腔112内的气体膨胀，致使前腔111与后腔112的气压不平衡时，后腔112可以通过通孔12进行泄压以平衡后腔112与前腔111之间的气压，进而保证扬声器箱100能够正常工作。所以，通过设置一个通孔12，既可以平衡后腔112与前腔111之间的气压又可以实现吸音颗粒的灌入，减少了通孔12的设置数量，简化了制作工艺。通过设置遮盖组件3遮盖通孔12，空气中的灰尘等杂质不能通过通孔12进入后腔112中，另外，为了防止通孔12自身的气体泄漏量太大，设置遮盖组件3以使后腔112中的气体透过遮盖组件3流到壳体1之外来调整气体泄漏量，因而，遮盖组件3既可以防尘又可以透气。因此，本申请提供的扬声器箱100既可以平衡后腔112与前腔111之间的气压又可以灌入吸音颗粒，并且结构简单、制造工艺简洁、制造成本低。
请再次参阅图2、图4和图5，遮盖组件3包括透气隔离件31和盖板32，透气隔离件31遮盖通孔12且固定于盖板32上，盖板32与壳体1连接并设于透气隔离件31之远离通孔12的一侧，盖板32设有盖孔321，后腔112中的气体依次流过通孔12、透气隔离件31和盖孔321流到壳体1之外。通过将透气隔离件31遮盖通孔12设置，空气中的灰尘等杂质被透气隔离件31阻挡，不能进入后腔112中，而后腔112中的气体能够透过透气隔离件31流到壳体1之外。通过在盖板32上设置盖孔321，防止透气隔离件31完全被盖板32遮盖，后腔112不能与外界连通，后腔112中的气体无法流到壳体1之外；另外，也减少了制造盖板32所需的材质的用量，降低了制造成本。
请再次参阅图4和图5，遮盖组件3还包括第一粘接件33，透气隔离件31通过第一粘接件33固定于盖板32上。可以理解，在其他实施例中，不设置第一粘接件33，透气隔离件31通过其他连接方式固定到盖板32上也是可以的。
优选地，第一粘接件33具有第一内孔331，第一内孔331的孔径大于或等于盖孔321的孔径。通过该种设置方式，扩大后腔112中的气体的泄漏量，当然，在其他实施例中，第一内孔331的孔径小于盖孔321的孔径也是可以的。
请再次参阅图2、图4和图5，遮盖组件3还包括第二粘接件34，盖板32通过第二粘接件34固定于壳体1上。可以理解，在其他实施例中，不设置第二粘接件34，盖板32通过其他连接方式与壳体1连接也是可以的。
优选地，第二粘接件34具有第二内孔341，透气隔离件31和第一粘接件33均容置于第二内孔341中。定义沿通孔12的轴向的方向为遮盖组件3的厚度方向，在本实施例中，第一粘接件33与透气隔离件31的厚度之和小于第二粘接件34的厚度。可以理解，在其他实施例中，第一粘接件33与透气隔离件31的厚度之和与第二粘接件34的厚度相同也是可以的，这样，位于通孔12处的壳体1对透气隔离件31也具有一定的支撑力。
优选地，第二内孔341的孔径大于通孔12的孔径。
优选地，盖孔321、第一内孔331、第二内孔341以及通孔12同轴设置。通过该种设置方式，有利于后腔112中的气体流到壳体1之外。
优选地，透气隔离件31为无纺布、尼龙编织网、羊毛编织网、金属网以及调音纸中的任意一种。无纺布、尼龙编织网、羊毛编织网、金属网以及调音纸均具有一定的声阻特性，可以用于调整气体泄漏量，以满足扬声器箱100的声学性能要求。虽然本实施例中指出透气隔离件31可以为无纺布、尼龙编织网、羊毛编织网、金属网以及调音纸中的任意一种，但是透气隔离件31并不限定为上述几种。
优选地，盖板32为包括聚对苯二甲酸乙二醇酯（PET）、聚碳酸酯（PC）、聚丙烯（PP）或丙烯腈-丁二烯-苯乙烯（ABS）中任意一种材质的面板。虽然本实施例中指出盖板32的材质为包括PET、PC、PP或ABS中的任意一种，但并不限定为上述几种，只要具有一定刚性的材料均可。
请再次参阅图2、图3和图5，壳体1之设有通孔12的部位设有孔径大于通孔12的沉孔13，通孔12从沉孔13的底部延伸连通容置腔11，透气隔离件31和盖板32均容置于沉孔13内。通过该种设置方式，盖板32不会凸出于壳体1之外，既方便扬声器箱100安装到智能手机、平板电脑等电子设备上，又美观大方。
优选地，壳体1包括前盖14和后盖15，前盖14和后盖15围合形成容置腔11，发声单体2与前盖14围合形成前腔111，发声单体2、前盖14和后盖15围合形成后腔112，通孔12贯穿设于后盖15，遮盖组件3固设于后盖15的外表面。
以上所述仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
