Description

一种电视机喇叭滑动式固定结构 技术领域
本发明涉及电视机内的喇叭固定，更具体地说，涉及一种液晶电视机、等离子电视机的电视机喇叭滑动式固定结构。
背景技术
目前，轻薄化是电视机发展的一个趋势，液晶电视及等离子电视都在向窄边框甚至无边框发展。为了达到外观效果，必须减小整机尺寸，因此，各品牌的液晶电视、等离子电视的声音系统以及喇叭的安装系统都在不断改善。常用的方式归类如下：(1)、采用小尺寸喇叭，缩小喇叭的占用空间；(2)、喇叭出音方向朝下或者朝后，使前壳上没有喇叭出音孔，前壳下边框可以做得更窄，外观更加美观；(3)、采用喇叭支架的形式以改变喇叭的安装和出音方式，从而减小整机尺寸和提高出音效果。而现有技术中的喇叭安装结构包括：
(1) 无喇叭支架的安装方式，其中为保证音质，喇叭需要尽可能的贴紧机壳。因此喇叭垫圈很容易在装配过程中被机壳挤压变形。变形的喇叭垫圈会碰到喇叭的振动膜，影响音质。
(2) 有喇叭支架的安装方式，其缺点是结构复杂，使用的部品数量多，安装工序多，成本高。
发明内容
本发明要解决的技术问题在于，针对现有技术的喇叭固定结构中喇叭垫圈容易变形或者成本高的问题，提供一种不需要喇叭支架及固定喇叭的螺钉，只利用前后壳及附件即可把喇叭良好固定的喇叭固定结构。
本发明解决其技术问题所采用的技术方案是：构造一种电视机喇叭滑动式固定结构，包括前壳和后壳，所述喇叭的两侧各设有一个连接耳，其特征在于，在每个所述连接耳上装有一个弹性件；每个所述弹性件包括设有限位孔的限位部分、设有插装孔的连接耳安装部分、以及受推部分；所述限位部分、连接耳安装部分及受推部分之间为依次连接的一体结构；每个所述弹性件通过其插装孔装于所述喇叭的其中一个连接耳上；所述前壳上设有两个固定结构的限位柱，每个所述弹性件的限位孔套在其中一个所述限位柱上，所述限位孔的内腔宽度大于所述限位柱的厚度，所述弹性件可基于所述限位柱移动、使所述限位柱可位于所述限位孔内的初始位置与最终位置之间任一位置；所述后壳上设有两个固定结构的推动件，在所述后壳安装过程中每个所述推动件会挤压其中一个所述弹性件上的受推部分，使所述弹性件基于所述限位柱移动，进而带动所述喇叭移动直至将其压紧安装到位。
本发明中，还可在每一个所述限位柱的外侧设置一个对所述弹性件起限制作用的挡片。
本发明中，所述后壳的下端设有可与所述前壳扣合的弯折面，所述喇叭安装到位时紧贴所述弯折面的内侧；所述限位柱由所述前壳内侧向后伸出；所述推动件由所述后壳内侧向前伸出；在所述后壳安装过程中每个所述弹性件位于其中一个所述推动件与所述弯折面内侧之间，且所述推动件与所述弯折面内侧之间的间距是由前向后逐渐变小的。
本发明中，在每个所述限位孔的内表面可设有与所述限位柱平行的小凸筋，用于在初始安装时确保所述限位柱位于所述限位孔内的初始位置。
本发明中，在每个所述弹性件的限位部分外表面设有与所述限位孔内表面的小凸筋对应的凹槽。
本发明中，所述受推部分可以是设于连接耳安装部分表面中部的圆柱状凸起，所述圆柱状凸起的轴向与所述限位孔的轴向之间为垂直关系。所述受推部分还可以是设于连接耳安装部分表面的斜坡结构。
本发明中，所述弹性件可以是橡胶弹性件、或硅胶弹性件。
由上述技术方案可以看出，本发明简化了喇叭的安装结构，减少了喇叭支架及固定螺钉的使用，降低了成本，提高了生产效率。该固定结构可以避免喇叭垫圈在安装过程中的破损，能够使喇叭与机壳更紧密地贴在一起，形成密闭的音腔，保证喇叭音质。弹性件的缓冲作用，能有效地减少喇叭振动引起的电视机零部件的共振，减少杂音的产生，提高产品的品质。

具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
本发明的一个优选实施例如图1～图10所示。其中，图6示出了电视机中的喇叭、前壳3、后壳4、主体5在整个电视机中的安装位置。该电视机是液晶电视机、等离子电视机或其他平板电视机。图6中示出的是电视机装配无过程中其正面向下时的情况，正常使用观看时，图6中的右侧向上，左侧向下，同时前壳3在前，后壳4在后。本文中将基于正常使用时的状态来描述各部件的位置关系。
如图1所示，在前壳的内表面设有两个限位柱31，它们从前壳内表面向后伸出。在两个限位柱的旁边分别设有一个对弹性件2起限制作用的挡片32。
本实施例中，弹性件2的结构如图2A～图2E所示，每个弹性件2包括限位部分21、连接耳安装部分22以及受推部分23，三者之间为依次连接的一体结构。其中，在限位部分21设有限位孔24；在连接耳安装部分设有插装孔25、以及受推部分23；而受推部分23为设于连接耳安装部分22表面中部的圆柱状凸起，该圆柱状凸起的轴向与限位孔的轴向之间为垂直关系。
如图2E所示，针对每个弹性件的限位部分，在其限位孔24的内表面设有两个对称的小凸筋26，用于在初始安装时确保限位柱位于限位孔24内的初始位置，即位于图2E中限位孔的下部。相应地，针对每个弹性件的限位部分，在其外表面设有与限位孔内表面的小凸筋26对应的两个对称的凹槽27。设置凹槽27的作用是增加该部位的弹性，使前述小凸筋26不会将限位柱卡得太紧，从而便于弹性件2的移动；弹性件受推后基于限位柱移动时，限位柱将由初始位置变动到最终位置。
如图3所示，本实施例中，喇叭1的两侧各设有一个连接耳11，每个弹性件2通过其插装孔25装于喇叭的其中一个连接耳上，具体来说是喇叭1的连接耳11插入到弹性件2的插装孔25中，得到图4所示的结构。
如图4所示，本实施例中，按图3所示的方式将弹性件2装于喇叭1的两位连接耳上之后，再将弹性件2装在前壳3上，具体来说，是将每个弹性件2的限位部分21的限位孔24套在其中一个限位柱31上，向下压之后得到图5所示的状态，且初始安装时限位柱31位于限位孔24内的初始位置。
在图5中可以看出两个挡片32可对弹性件起到限制作用，防止其向两侧移动，同时也便于安装过程中的定位。完成图5所示的安装之后，再装后壳4，即如图6所示的结构，图7～图10则示出了安装过程的局部放大示意图。
由图7可以看出，限位孔24内腔的上下宽度(图中在左右宽度)大于限位柱的上下厚度(图中是左右厚度)，所以，套装在限位柱上的弹性件2可基于该限位柱上下移动(图中是左右移动)、使限位柱31可位于限位孔24内的初始位置与最终位置之间任一位置。在图7中限位柱31位于限位孔24中的初始位置，在图9中限位柱31位于限位孔24中的最终位置。
由图7可以看出，在后壳4上设有两个固定结构的推动件41(图中只画出了一个)，也就是说，本发明中的弹性件2、限位柱31、以及推动件41均为两个，可分为两组，且同一组中弹性件正好可套在限位柱上，推动件则正好可压在弹性件上，位置一一对应，从而可相互作用。
从图7可以看出，在后壳4的端部设有可与前壳3扣合的弯折面42，喇叭1被安装到位时会紧贴该弯折面42的内侧。推动件41由后壳内侧向前伸出，在安装过程中，每个弹性件2位于其中一个推动件41与弯折面42内侧之间，且推动件41与弯折面42内侧之间的间距是由前向后逐渐变小的(在图7中则体现为由上向上逐渐变小)。
安装过程中，需将图7中的后壳4向下压，此时推动件41会挤压弹性件2上的受推部分23，使弹性件2基于限位柱向下移动(在图7中是向左移动)，进而带动喇叭1移动、直至将其压紧安装到位。如图8所示是与图7对应的立体结构图。
如图9所示，当后壳4安装到位、与前壳3扣合时，弹性件2也被推动件41推动到了最终位置，此时限位柱也从图7所示的位于限位孔内的初始位置、变为图9所示位于限位孔内的最终位置了。如图10所示是与图9对应的立体结构图。
本实施例中，所述弹性件可以是橡胶弹性件、或硅胶弹性件，具有适当的弹性，所以可带动着喇叭移动，并使之与后壳弯折面42的内表面紧贴。。
可见，本实施例中只利用前壳、后壳把弹性件夹紧即可固定喇叭，在后壳安装到位的同时把喇叭推到位，并压紧弹性件，使喇叭固定；在喇叭安装到位之前，喇叭垫圈始终与后壳没有接触，这样就避免了后壳把喇叭垫圈挤压变形。本发明利用弹性件的缓冲性能，有效地防止电视机共振产生的杂音，从而提高产品质量。
本发明的另一个实施例如图11～图12所示，它与前一实施例的区别在于弹性件结构略有不同，由图11A、图11B可以看出，针对每个弹性件200，其受推部分203为设于连接耳安装部分表面的斜坡结构。斜坡结构的受推部分203为与后壳上的推动件41之间的配合关系如图12所示。此各结构也可将弹性件推动到位以实现喇叭的正确安装。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护之内。
