 本发明的实施方式
下面结合附图和实施方式对本发明作进一步说明。
如图1至图4所示，是本发明实施例一提供的一种发声器件，该发声器件包括上盖1、与上盖1合围形成收容空间50的下盖2以及收容于收容空间50内的发声单体3，发声单体3具有振膜31，上盖1包括朝向振膜31的顶壁12以及自顶壁12向靠近振膜31方向延伸的的固定发声单体3的侧壁13，上盖1设有出音孔11，顶壁12、侧壁13以及振膜31合围形成前腔4。
上述实施例中，如图3和图4所示，上盖1还包括自顶壁12向远离振膜31方向凹陷的凹陷部14，凹陷部14包括朝向振膜31的第一表面141以及连接第一表面141和顶壁12的第二表面142，第一表面141从第二表面142至出音孔11的方向上延伸至出音孔11，第二表面142自其中一个侧壁13横跨至相对的另一侧壁13。由于第一表面141在竖直方向的高度高于顶壁12，第一表面141与发声单体3的距离大于顶壁12与发声单体3的距离，故可有效疏导发声单体3和上盖1之间的前腔4区域两边的气压，使得前腔4内部各处压强平衡，可改善振膜31摇摆的问题。优选的，顶壁12表面为平面，第一表面141平行于顶壁12，第二表面141垂直于顶壁12。
另外，发声单体3、上盖1与下盖2围成与前腔4相对的后腔5，也就是说，在本实施例中，发声单体3将收容空间50分隔为前腔4和后腔5，后腔5可用于改善该发声设备的声学性能。顶壁12的远离出音孔11的一侧设置有朝向后腔5方向延伸的间隔壁18，间隔壁18整圈环绕设置，间隔壁18的底端面固定有第一透气隔离件20，第一透气隔离件20、间隔壁18以及顶壁12合围形成用于填充吸声材料的容纳腔6。顶壁12还设置有连通容纳腔6与外界环境的开口部16，开口部16处盖设有密封片30，密封片30密封开口部16。容纳腔6用于收容吸声材料，形成虚拟声腔，并通过该虚拟声腔来改善发声器件的声学性能。为了便于将吸声材料装入容纳腔6中，可通过开口部16向容纳腔6内灌装吸声材料，然后利用密封件30密封开口部16，这样不会导致粉末状吸声材料向外溢出。另外，上盖1还开设有泄露孔17，泄露孔17连通后腔5与外界环境，泄露孔17上盖设有第二透气隔离件40。后腔5内部可由泄露孔17和第二透气隔离件40实现气压平衡。
发声器件还包括垫片8，垫片8夹设于发声单体3的底部与下盖2之间，垫片8可以抑制发声单体3工作时引起的壳体共振，从而可以提高产品的性能。发声器件还包括贴设于出音孔11外侧的防尘隔垫7。另外，发声器件还连接有具有连接端91和插接端92的柔性电路板9，发声单体3与柔性电路板9的连接端91电连接，柔性电路板9的插接端92与下盖2的底壁固定连接，柔性电路板9用于连接发声单体3与外部电路。
如图5至图8所示，是本发明实施例二提供的一种发声器件。上盖1还包括自顶壁12向靠近振膜31方向突起的突起部15，突起部15包括朝向振膜31的第三表面151以及连接顶壁12和第三表面151的第四表面152，第三表面151从第四表面152至远离出音孔11的方向上延伸至与出音孔11相对的其中一个侧壁13，第四表面152自其中一个侧壁13横跨至相对的另一侧壁13。突起部15进一步改变了前腔5内部的空间，前腔5内部的气压得到进一步疏导，内部压强也更加平衡。优选的，顶壁12表面为平面，第三表面151平行于顶壁12，第四表面152垂直于顶壁12。除上述结构外，该实施例二的其他结构均与实施例一相同，在此不再赘述。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
