Description

扬声器和电子设备 技术领域
本发明涉及声能转换技术领域，特别涉及一种扬声器和电子设备。
背景技术
在扬声器与整机安装时，为了保证扬声器与整机之间的密封性，通常，在扬声器上设有弹性件，弹性件围绕扬声器的出声孔设置，并与整机壳体抵接，实现对出声孔的密封。然而，由于弹性件是粘接在扬声器上的，粘接的可靠性较低，同时在扬声器与整机组装过程中，扬声器会相对整机移动，弹性件与整机壳体之间会产生碰撞挤压，容易导致弹性件相对扬声器移动，导致密封效果变差。
发明内容
本发明的主要目的是提出一种扬声器，旨在保证扬声器和整机配合的密封性。
为实现上述目的，本发明提出的扬声器，包括扬声器单体和收容所述扬声器单体的壳体，所述壳体上设有出声孔，且所述壳体的外表面涂设有弹性胶体，所述弹性胶体沿所述出声孔设置而呈环状，所述弹性胶体用以与电子设备密封抵接。
可选地，所述壳体的外表面设有容置槽，所述容置槽沿所述出声孔设置而呈环状，所述弹性胶体涂设于所述容置槽。
可选地，所述弹性胶体与所述出声孔的孔缘间隔设置。
可选地，所述弹性胶体与所述出声孔孔缘之间的距离处处相等。
可选地，所述弹性胶体的厚度为0.1mm-0.5mm。
可选地，所述弹性胶体的宽度为0.3mm-0.7mm。
可选地，所述弹性胶体为硅胶或硅橡胶。
可选地，所述壳体包括上壳和下壳，所述上壳和所述下壳结合形成收容 所述扬声器单体的空间，所述出声孔以及所述弹性胶体均设置在所述上壳。
本发明还提出一种电子设备，电子设备包括机壳以及扬声器，所述扬声器包括扬声器单体和收容所述扬声器单体的壳体，所述壳体上设有出声孔，且所述壳体的外表面涂设有弹性胶体，所述弹性胶体沿所述出声孔设置而呈环状，所述弹性胶体与所述机壳密封抵接。
本发明中，通过在扬声器的壳体上且环绕出声孔设置弹性胶体，当将该扬声器安装至终端电子设备上时，弹性胶体与电子设备的机壳密封抵接，能够保证扬声器的出声孔的边缘与电子设备的机壳之间结合的密封性，保证电子设备整体的声学性能。另外，由于弹性胶体是通过涂抹的方式涂设在扬声器的壳体上的，该涂抹的方式使得弹性胶体与扬声器壳体之间的结合性能更好，形成类似一个整体的结构，因此两者更具稳定性，故可避免弹性胶体被碰撞时相对扬声器的壳体产生移动，从而可保证扬声器和整机配合的密封性。一般地，在扬声器上粘接有密封件而与机壳抵接，由于密封件的形状是固定的，为了适应不同形状的扬声器，需要加工出不同形状的密封件，该采用密封件的方式适用性较差，导致生产成本较高。而本发明中，仅需要根据出声孔的形状或是扬声器的形状涂抹弹性胶体即可，可以适用于各种复杂形状的扬声器。再者，由于本发明中涂抹的方式不需要再额外设置粘接层，相当于省略了粘接层的这一厚度，因此相较于粘接密封件的形式而言，本发明中的扬声器与整机结合后的整体厚度更小，可以更好的利用整机空间。

本发明提出一种扬声器。
请参考图1，扬声器10包括壳体11和扬声器单体，壳体11内形成有收容腔，且壳体11上设有出声孔111，扬声器单体设于收容腔内，并将收容腔隔设为前声腔和后声腔，出声孔111与前声腔连通。本实施例中，扬声器单体包括振动系统和磁路系统，振动系统包括振膜以及固定于振膜一侧的音圈， 振膜包括中心部、围绕中心部设置的折环部以及围绕折环部设置的固定部，振膜还可以包括结合于中心部的复合层。扬声器单体还可包括辅助系统，辅助系统包括外壳，外壳用于收容固定振动系统和磁路系统。此外，辅助系统还可包括前盖，前盖结合于外壳的上方，前盖和外壳围合成扬声器单体的保护框架。磁路系统包括与外壳固定的导磁轭，导磁轭上设有内磁路部分和外磁路部分，两者之间形成容纳音圈的磁间隙。其中，一种情况下，内磁路部分包括设于导磁轭的中央位置的中心磁铁和设于中心磁铁上的中心导磁板，外磁路部分包括设于导磁轭的边缘位置的边磁铁和设于边磁铁上的边导磁板。
本实施例中，壳体11包括上壳和下壳，上壳和下壳结合形成收容固定扬声器单体的收容腔。可选地，扬声器单体与上壳共同围成前声腔，扬声器单体、下壳和上壳共同围合形成后声腔。在其它实施例中，壳体11还可包括中壳，扬声器单体与上壳和中壳共同围成前声腔。
可选地，出声孔111设置在上壳；另外，也可在上壳和下壳均开设缺口而共同构成出声孔111。需要说明的是，该扬声器10可为侧出声结构或者是正出声结构，即该扬声器10的出声孔111可正对扬声器单体的振膜设置，当然，扬声器10的出声孔111也可与扬声器单体的振膜错开设置，即位于振膜的侧面。
本发明实施例中的扬声器10是安装在电子设备上的，在进行整机装配时，扬声器10的出声孔111与电子设备的机壳20(如图2所示)结合，并与机壳20上的声孔21相连通，以保证声音的传递。但是扬声器10与电子设备的机壳20结合时，由于两者接触的位置的气密性较差，故会大大降低电子设备的音效。
为解决上述问题，本实施例中，所述壳体11的外表面涂设有弹性胶体12，弹性胶体12沿出声孔111设置而呈环状，弹性胶体12用以与电子设备密封抵接。该实施例中，在进行涂设之前，弹性胶体12呈流体状态，当将弹性胶体12涂抹到壳体11上后，弹性胶体12通过风干可呈现固态，并实现与壳体11的贴合固定。本实施例中的弹性胶体12为硅胶或硅橡胶等具有密封性能的材质。此外，弹性胶体12可为圆环形、椭圆环形、跑道型或方形等等，本发 明实施例中对此并不进行限定。
本发明中，通过在扬声器10的壳体11上且环绕出声孔111设置弹性胶体12，当将该扬声器10安装至终端电子设备上时，弹性胶体12与电子设备的机壳20密封抵接，能够保证扬声器10的出声孔111的边缘与电子设备的机壳20之间结合的密封性，保证电子设备整体的声学性能。另外，由于弹性胶体12是通过涂抹的方式涂设在扬声器10的壳体11上的，该涂抹的方式使得弹性胶体12与扬声器10壳体11之间的结合性能更好，形成类似一个整体的结构，因此两者更具稳定性，故可避免弹性胶体12被碰撞时相对扬声器10的壳体11产生移动，从而可保证扬声器10和整机配合的密封性。一般地，在扬声器10上粘接有密封件而与机壳20抵接，由于密封件的形状是固定的，为了适应不同形状的扬声器10，需要加工出不同形状的密封件，该采用密封件的方式适用性较差，导致生产成本较高。而本发明中，仅需要根据出声孔111的形状或是扬声器10的形状涂抹弹性胶体12即可，可以适用于各种复杂形状的扬声器10。再者，由于本发明中涂抹的方式不需要再额外设置粘接层，相当于省略了粘接层的这一厚度，因此相较于粘接密封件的形式而言，本发明中的扬声器10与整机结合后的整体厚度更小，可以更好的利用整机空间。
本实施例中，壳体11的外表面设有容置槽(图未示出)，容置槽沿出声孔111设置而呈环状，弹性胶体12涂设于容置槽。通过设置容置槽来供弹性胶体12涂抹的方式，能够避免溢胶现象，防止弹性胶体12溢入出声孔111内而影响扬声器10的音效。可选地，弹性胶体12部分伸出容置槽设置，可保证弹性胶体12与机壳20之间更好接触。当然，壳体11上也可不设置容置槽。
本实施例中，弹性胶体12与出声孔111的孔缘间隔设置，如此当壳体11的外表面涂抹较多的弹性胶体12时，即使出现溢胶现象，弹性胶体12和出声孔111的孔缘之间的间隔能够容纳较多的溢出胶体，大大减少甚至可避免弹性胶体12溢入出声孔111。可选地，弹性胶体12与出声孔111孔缘之间的距离处处相等。由于在进行整机装配时，机壳20上的声孔21与扬声器10的出声孔111一般是正对设置的，即两者的轴向大体上重合，故将弹性胶体12与出声孔111孔缘之间的距离设置为处处相等，相当于弹性胶体12与机壳20 上的声孔21孔缘之间的距离也是处处相等的，可避免弹性胶体12在一些位置距离机壳20的声孔21孔缘较远，而在另一些位置距离机壳20的声孔21孔缘过近而伸入到机壳20的声孔21内的现象，因此可保证弹性胶体12与机壳20具有更好的抵接密封效果。
可选地，弹性胶体12的厚度为0.1mm-0.5mm，例如，在一些实施例中，弹性胶体12的厚度为0.35mm，在其它实施例中，弹性胶体12的厚度可为0.1mm、0.3mm或是0.5mm等等。通过采用该厚度的弹性胶体12，能够避免弹性胶体12过厚而占用过多的整机空间，同时也能够避免弹性胶体12过薄而导致密封效果较差。
可选地，弹性胶体12的宽度为0.3mm-0.7mm。例如，在一些实施例中，弹性胶体12的宽度为0.5mm，在其它实施例中，弹性胶体12的宽度可为0.3mm、0.4mm或是0.7mm等等。通过采用该宽度的弹性胶体12，能够避免弹性胶体12过宽而占用过多的整机空间，同时也能够避免弹性胶体12过窄而导致密封效果较差。
本发明还提出一种电子设备，该电子设备包括如上的扬声器10，由于该电子设备采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。具体而言，电子设备可以是手机、平板或电脑等能够发声的设备。电子设备包括机壳20，在机壳20上设有声孔21，扬声器10安装在机壳20内，扬声器10上的出声孔111与声孔21连通，并且扬声器10的弹性胶体12与机壳20密封抵接，弹性胶体12同样是环绕声孔21设置。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
