所述上壳101在对应所述前声腔的位置设置有连通孔107，具体地，所述上壳101形成承载区，在所述承载区内设置加强件106，在所述加强件106上开设连通孔107，所述上壳,11的外表面上盖设有盖体104，所述盖体104内形成有腔体，所述盖体104与所述连通孔107的位置相对应，使得所述腔体通过所述连通孔107与所述前声腔连通。所述盖体104通过粘接剂108与加强件106固定，其中本例子中所述加强件106为大钢片，所述粘接剂108采用热熔胶。
本例子中盖体置于前声腔的外部，所述盖体上的腔体与前声腔连通，不仅增大了扬声器单体的前声腔的体积，而且改善了发声装置的中高音频频响，提高了声学性能。
需要说明的是，以上实施方式中，发声装置的外部壳体具体包括三部分壳体，即上壳102、中壳102和下壳103，实际上，本技术方案也同样适用于仅包括两部分壳体或者其他数量的壳体情况。其次，发声装置既可以 是侧出声模组，也可以是正出声模组结构。当应用于侧出声模组时，发声装置在外部壳体的侧面出声，此时，可以优选的将盖体设置在上壳的顶表面的外侧(如实施方式附图中所示)；如果应用于正出声的模组时，由于上壳的顶部为出声口，因此可以优选的考虑将盖体设置在外部壳体的侧部。以上实现方式一方面腔体不会占据外部壳体上用于设置出声口的表面空间，另一方面腔体也不必受限于出声口的设置需求等因素，可以充分利用外部壳体的各个表面的空间进行灵活选择。另外，以上实施方式中，设置在前声腔外部的腔体设置有一个，盖体也对应设有一块，但具体实施时，外部的腔体可以设置有多个，当设置多个时，多个腔体既可以是形成在一块儿盖体内，也可以是形成在多块盖体内。其中，当形成在一块儿盖体内时，多个腔体之间可以通过隔板分隔开，隔板可以是与盖体一体成型的部件，也可以是单独结合在盖体上的部件。当形成在多块盖体上时，很容易理解的是，每个盖体可以对应一个连通孔，每个腔体在盖体内部成型并且通过对应的连通孔与前声腔连通。各腔体之间可以串联，也可以并联。
再者，由于本技术方案中，将用作共振腔的腔体设置在了前声腔的外部，考虑到当前电子产品越来越薄型化的趋势，在具体应用时，可以充分根据厚度等需求去灵活设计盖体的尺寸和体积，以尽量减小其在竖直方向上所占据的空间。
根据本发明一个实施例，提供一种电子产品，所述电子产品包括上述所述发声装置；产品主体，所述发声装置设置在所述产品主体内部。本例子中能够提高电子产品的声学性能。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
