本申请提出一种共振扬声器100。可以理解的，该共振扬声器100应用于电子设备，所述电子设备可以为吸油烟机等在油烟环境中使用的电子设备，其包括电子设备主体，所述共振扬声器100固设于所述电子设备主体上。
本实施例以电子设备为吸油烟机500为例进行说明，所述吸油烟机500包括油烟机主体300。
请结合参照图1、图2、图3、图4和图5所示，在本申请实施例中，该共振扬声器100包括扬声器主体1和共振头2，其中，共振头2设置在油烟机主体300的预订区域，共振头2包括底座21和多个支撑臂22，支撑臂22与底座21的周缘相连，且与油烟机主体300固定连接；扬声器主体1设置在共振头2远离油烟机主体300的一侧。
在本实施例中，共振扬声器100可通过共振头2的底座21和多个支撑臂22与油烟机主体300实现连接。可以理解的，共振扬声器100可固定连接于油烟机主体300的预订区域，例如采用焊接或过盈配合等方式将共振头2的底座21和多个支撑臂22固定连接在油烟机主体300的预订区域。当然，在其他实施例中，共振扬声器100也可通过可拆卸连接的方式固定于油烟机主体300的预订区域，例如采用卡扣连接、插接配合、螺钉连接或销钉连接等方式，将将共振头2的底座21和多个支撑臂22连接在油烟机主体300的预订区域。需要说明的是，上述预订区域可以是油烟机主体300上设置的用于容纳共振扬声器100的避位区域，并且有利于共振扬声器100的底座与油烟机主体300中的玻璃盖板连接。
作为本实施例的一种可选方案，共振头2的多个支撑臂22可通过螺钉与油烟机主体300连接，共振头2的底座21可采用胶层粘结于油烟机主体300，如此设置，可有利于提高共振扬声器100的安装稳固性。
可以理解的，共振头2用于安装固定扬声器主体1，共振头2的结构可以是安装板、安装台或安装壳等，在此不做限定。在本实施例中，共振头2与扬声器主体1装配为一体结构，为了方便扬声器主体1的安装固定，共振头2的底座21与扬声器主体1的外形轮廓相匹配。
在本实施例中，扬声器主体1包括上壳11、下盖12、支撑骨架13、磁铁14、线圈15及导振片16，利用支撑骨架13对扬声器主体1实现支撑安装，利用上壳11和下盖12配合支撑骨架13将磁铁14装配在上壳11和下盖12之间。线圈15固定于导振片16上，并与下盖12连接。导振片16通过粘贴的方式将组装后的扬声器主体1固定于共振头2的底座21上。
在一实施例中，扬声器主体1的上壳11、下盖12、磁铁14、线圈15及导振片16均呈圆形设置。支撑骨架13用于支撑和安装扬声器主体1，支撑骨架13的结构可以是支架、安装板或安装架等，在此不做限定。
在本实施例中，共振头2的底座21可选为圆环形。为了方便通过共振头2固定共振扬声器100，底座21上连接有多个支撑臂22，如此可利用支撑臂22与油烟机主体300连接，以实现共振扬声器100的装配和固定。
本申请技术方案的共振扬声器100通过在共振头2的底座21设置多个支撑臂22，利用多个支撑臂22分别与油烟机主体300连接，从而提高共振扬声器100的安装稳定性；同时，通过将支撑臂22设置在共振头2上，从而简化了共振扬声器100的结构。
在本实施例中，支撑臂22与油烟机主体300采用固定连接方式，例如焊接、过盈配合等，如此可提高安装的稳固性；当然，支撑臂22与油烟机主体300也可采用可拆卸连接方式，例如卡扣连接、插接配合、螺钉连接或销钉连接等，在此不做限定，如此可方便共振扬声器100的拆装、更换及维修等。
在本实施例中，共振头2的底座21设置有多个支撑臂22。可选地，支撑臂22为两个、三个或三个以上等，在此不做限定。
在一实施例中，如图4和图5所示，所述底座21和多个所述支撑臂22为一体成型结构。可以理解的，将支撑臂22和底座21设置为一体成型结构，如此既可以提高共振头2的结构强度，同时还可以简化共振头2的加工步骤。当然，在其他实施例中，支撑臂22与底座21也可为分体结构设置，在此不做限定。
在一实施例中，如图4和图5所示，多个所述支撑臂22和所述底座21位于同一平面。可以理解的，通过将支撑臂22和底座21设置在同一平面内，从而同时利用支撑臂22和底座21与油烟机主体300进行连接，从而增大了共振头2的接触面积，从而提高共振头2与油烟机主体300的连接稳定性。
在一实施例中，如图4和图5所示，多个所述支撑臂22等间距地设置在所述底座21的周缘，也即多个所述支撑臂22均匀分布于所述底座21的周缘。在本实施例中，等间距为相邻的两个支撑臂22之间的最小距离相同。可以理解的，将多个支撑臂22均匀设置在底座21的周缘，从而在多个支撑臂22与油烟机主体300连接，使得共振扬声器100能够受力均匀，进一步提高共振扬声器100的安装稳定性。
在一实施例中，如图1、图2、图3、图4和图5所示，所述共振头2包括两个所述支撑臂22，两个所述支撑臂22对称设于所述底座21的相对两侧，并朝向相互背离的方向延伸。如此可利用对称设置的两个支撑臂22实现共振扬声器100的稳固安装。
在本实施例中，底座21呈圆形板状结构，并在底座21的中心开孔，从而方便扬声器主体1的其他部件方便装配。可选地，支撑臂22呈方形或长条形的板状结构，如此可提高支撑臂22与油烟机主体300的接触面积。
在一实施例中，如图2、图3、图4和图7所示，所述支撑臂22面向所述扬声器主体1的一侧设有凸柱221，所述凸柱221设有空腔222，所述支撑臂22上对应所述凸柱221的区域设有过孔223，所述过孔223连通所述空腔222。
可以理解的，通过在每一支撑臂22上设置具有空腔222的凸柱221，并在支撑臂22上设置连通空腔222的过孔223，从而方便油烟机主体300上的连接结构穿过过孔223和空腔222，如此可利于紧固件等结构进一步提高安装稳固性。
在本实施例中，凸柱221的空腔222可以是通孔或通槽结构。如图4和图5所示，所述凸柱221与所述支撑臂22为一体成型结构，如此设置既可以提高凸柱221和支撑臂22的连接结构强度，同时也简化了共振头2的加工步骤。
在一实施例中，所述空腔222的外径为7mm~10mm。可选地，空腔222的外径为7mm、8mm、9mm、10mm等，在此不做限定。所述空腔222的内径为4mm~6mm。可选地，空腔222的内径为4mm、5mm、6mm等。
在本实施例中，所述空腔222的内径与所述过孔223的内径相同，如此可确保油烟机主体300上的连接结构顺利穿过过孔223，并伸入空腔222内。也即凸柱221为空心柱体，如此可利用该空心柱体与油烟机主体300的连接相互装配，并通过螺丝锁紧，即可保证共振扬声器100不会产生剥离风险。
在一实施例中，如图2、图3和图4所示，所述支撑臂22的周缘凸设有加强筋224，所述加强筋224朝向所述扬声器主体1的一侧延伸。可以理解的，通过在支撑臂22上设置加强筋224，可有利于加强支撑臂22的结构。
在本实施例中，所述加强筋224与所述支撑臂22为一体成型结构，如此进一步提高支撑臂22和加强筋224之间的结构强度，且有利于简化加工工艺。
在一实施例中，所述加强筋224的厚度为1mm~2mm。可以理解的，加强筋224的厚度为加强筋224突出支撑臂22表面的高度，加强筋224的厚度可选为1mm、1.3mm、1.5mm、1.8mm、2mm等，在此不做限定。所述加强筋224的宽度为1mm~2mm。可以理解的，加强筋224的宽度为加强筋224在支撑臂22表面的投影宽度。加强筋224的宽度可选为1mm、1.3mm、1.5mm、1.8mm、2mm等，在此不做限定。
在一实施例中，为了进一步加强共振扬声器100的安装稳定性，如图3和图5所示，所述底座21远离所述扬声器主体1的一侧设有胶层211。
在一实施例中，胶层211为亚克力（VHB）胶，如此可利用底座21的胶层211与油烟机主体300的玻璃盖板粘附，进而提高连接稳定性。在本实施例中，为了保护胶层211的粘性，胶层211背向底座21的一侧设置有离型纸。使用时，将胶层211上附着的离型纸去除后，可以将该共振扬声器粘附在油烟机主体300的玻璃盖板上，然后将共振扬声器的支撑臂22与油烟机主体300固定连接。由此，提高了共振扬声器的安装稳定性。
本申请的共振扬声器100通过在共振头2的底座21设置多个支撑臂22，利用多个支撑臂22与底座21的配合结构，即可保证共振扬声器100与油烟机主体300的装配可靠性，杜绝剥离风险，并且此种装配方案适用于各种采用共振扬声器100的产品，具有广泛的应用前景。
如图6所示，本申请还提出一种吸油烟机500，包括上述油烟机主体300和上述的共振扬声器100，所述共振扬声器100固设于所述油烟机主体300上。该共振扬声器100的具体结构参照前述实施例，由于本吸油烟机500采用了前述所有实施例的全部技术方案，因此至少具有前述实施例的技术方案所带来的所有效果，在此不再一一赘述。
为了提高共振扬声器100与玻璃盖板310的连接稳定性，以及方便装配共振扬声器100，如图6、图7和图8所示，在一实施例中，所述油烟机主体300包括玻璃盖板310和固定支架320，所述固定支架320设置在所述玻璃盖板310的一侧，且所述固定支架320设置有避位区域321，所述固定支架320上环绕所述避位区域321的边缘设置有多个连接柱322。其中，所述共振扬声器100的支撑臂22与所述连接柱322一一对应地固定连接，且所述底座21与所述避位区域321对应设置；所述底座21穿过所述避位区域321与所述玻璃盖板310连接。
在本实施例中，所述固定支架320对应所述共振扬声器100的底座21设有避位区域321，所述固定支架320环绕所述避位区域321设有多个连接柱322，所述共振扬声器100的每一支撑臂22与一所述连接柱322连接，以使所述底座21与所述避位区域321正对。
可以理解的，通过在玻璃盖板310设置固定支架320，利用固定支架320固定装配共振扬声器100，提高了装配便利性。在本实施例中，玻璃盖板310与固定支架320可采用一体成型结构，如此有效简化结构，提高结构强度。当然，在其他实施例中，玻璃盖板310与固定支架320也可采用分体结构设置，此时固定支架320通过胶黏等方式固定于玻璃盖板310上，在此不做限定。
在本实施例中，为了进一步提高共振扬声器100的安装稳定性，固定支架320对应共振头2的底座21设有避位区域321，如此可利用避位区域321避位底座21的胶层211，从而使得胶层211直接与玻璃盖板310直接实现固定连接。
通过在固定支架320上设置多个连接柱322，使得每一连接柱322与每一支撑臂22对应，且可穿设于凸柱221的空腔222内，如此不仅可以实现定位安装，同时可提高安装稳定性。
在本实施中，固定支架320上的多个连接柱322可选为螺丝柱。连接柱322穿设于凸柱221的空腔222内，此时为了便于装配，并提高装配效率，连接柱322的外壁与空腔222的内壁之间具有间隙，该间隙为0.1mm~0.3mm。可选地，连接柱322的外壁与空腔222的内壁之间的间隙为0.1mm、0.2mm、0.3mm等。
在本实施例中，连接柱322的高度小于凸柱221的高度。可选地，凸柱221的高度与连接柱322的高度之差为1mm~2mm。如此可方便在连接柱322内设置攻牙，方便螺钉攻入连接柱322中，并与凸柱221的端部抵接限位。
在本实施例中，共振扬声器100的装配过程为：先将共振头2底座21胶层211上的离型纸去除，将支撑臂22上的凸柱221与连接柱322对准，并使得连接柱322穿过过孔223伸入凸柱221的空腔222内，此时确保底座21的胶层211穿过避位区域321与玻璃盖板310粘贴附着，然后将螺钉攻入连接柱322中，并压紧凸柱221的端部，如此可完成共振扬声器100的装配。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的构思下，利用本申请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申请的专利保护范围内。
