 本发明的实施方式
下面结合图1至图10对本实用新型作详细描述。
需要说明的是，本实用新型实施例中所有方向性指示(诸如上、下、左、右、前、后、内、外、顶部、底部……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
还需要说明的是，当元件被称为“固定于”或“设置于”另一个元件上时，该元件可以直接在另一个元件上或者可能同时存在居中元件。当一个元件被称为“连接”另一个元件，它可以是直接连接另一个元件或者可能同时存在居中元件。
请参阅图1至图3，本实用新型实施例提供一种扬声器100，包括盆架1、支撑于盆架1的振动系统2以及驱动振动系统2振动发声的磁路系统3，磁路系统3具有磁间隙31，振动系统2包括振膜组件21、插设于磁间隙31中的音圈22以及连接振膜组件21与音圈22的骨架组件23；骨架组件23包括第一骨架231与第二骨架232，音圈22沿振膜组件21的振动方向包括第一端221和第二端222，第一骨架231设于第一端221与振膜组件21之间，第二骨架232的一端固定于第二端222。
通过设置连接音圈22与振膜组件21的第一骨架231，确保音圈22震动时，将振动从音圈22传送到振膜组件21，从而使振膜组件21振动发声；通过将音圈22沿振动组件的振动方向设置第一端221和第二端222，第一骨架231的一端固定于音圈22的第一端221，第二骨架232的一端固定于音圈22的第二端222，确保音圈22向第一端221的方向位移时，第一骨架231对音圈22产生一定的阻力，减小音圈22与第二骨架232之间的撕扯力，音圈22向第二端222的方向位移时，第二骨架232对音圈22产生一定的阻力，减小音圈22与第一骨架231之间的撕扯力；因此，本实用新型实施例提供的扬声器100增加了音圈22连接到骨架组件23的稳定性，提高了扬声器100的性能。
请参阅图4至图7，第一骨架231包括第一固定部2311、第二固定部2312以及连接第一固定部2311与第二固定部2312的第一连接部2313，第一固定部2311粘接固定于第一端221，第二固定部2312粘接固定于振膜组件21。第二骨架232包括第三固定部2321、第四固定部2322以及连接第三固定部2321与第四固定部2322的第二连接部2323，第三固定部2321粘接固定于第二端222，第四固定部2322粘接固定于第二固定部2312。在其他实施例中，第一固定部2311可以通过其他方式固定于第一端221，第二固定部2312可以通过其他方式固定于第一端221，第三固定部2321可以通过其他方式固定于第二端222，第四固定部2322可以通过其他方式固定于第二固定部2312。当然，作为一种替代方式，第四固定部2322固定于振膜组件21的其他部位或者固定于盆架1也是可以的。
第一固定部2311、第二固定部2312、第三固定部2321以及第四固定部2322均呈环形，第一固定部2311的直径小于第二固定部2312的直径，第三固定部2321的直径小于第四固定部2322的直径，其中，第三固定部2321的直径与第一固定部2311的直径相等。第一连接部2313和第二连接部2323均设有多个，多个第一连接部2313间隔分布，多个第二连接部2323间隔分布。具体地，第二连接部2323的数量与第一连接部2313的数量相同，并且一个第二连接部2323对应于一个第一连接部2313。
优选地，音圈22包括相对设置的第一固定面223和第二固定面224，第一固定面223设于第一端221，第二固定面224设于第二端222，第一固定部2311固定于第一固定面223，第三固定部2321固定于第二固定面224。通过该种设置方式，当音圈22向第一端221的方向位移时，第一骨架231能对音圈22产生更加有效的阻力，减小音圈22与第二骨架232之间的撕扯力；当音圈22向第二端222的方向位移时，第二骨架232对音圈22产生更加有效的阻力，减小音圈22与第一骨架231之间的撕扯力。
在本实施例中，盆架1包括环形的第一底壁11、环设于第一底壁11外侧的第二底壁12、由第二底壁12的外周缘弯折延伸的外壁13以及由第一底壁11的内周缘弯折延伸的内壁14，外壁13环绕内壁14且与内壁14间隔设置，内壁14围成容纳空间15，磁路系统3容纳于容纳空间15内。内壁14设有多个贯穿其上的通口141，通口141沿振膜组件21的振动方向延伸。
请参阅图9，磁路系统3包括磁碗组件以及固定于磁碗组件内的磁钢单元34，磁碗组件固定于盆架1的内壁14并容纳于容纳空间15中。具体地，磁碗组件包括正对设置的第一磁碗32和第二磁碗33，第一磁碗32设于内壁14靠近第一底壁11的一侧，第二磁碗33设于内壁14远离第一底壁11的一侧。第一磁碗32包括第一磁碗底壁321和第一磁碗侧壁322，磁钢单元34固定于第一磁碗底壁321，第一磁碗侧壁322设于第一磁碗底壁321且围绕磁钢单元34周向设置。第二磁碗33包括第二磁碗底壁331和第二磁碗侧壁332，第二磁碗底壁331与第一磁碗底壁321间隔正对设置且盖设于磁钢单元34，第二磁碗侧壁332设于第二磁碗底壁331且围绕磁钢单元34周向设置。磁钢单元34与第一磁碗侧壁322和第二磁碗侧壁332共同形成磁间隙31，音圈22套设于磁钢单元34。第二磁碗33将磁钢单元34远离第一磁碗底壁321的一侧的磁力线导回至磁间隙31内，使磁路系统3的磁力线得到充分利用，从而有效提升扬声器100的灵敏度。
在本实施例中，第一磁碗侧壁322和第二磁碗侧壁332正对设置，两者之间设有缝隙。在其他实施例中，第一磁碗侧壁322可以抵接于第二磁碗侧壁332。
请再次参阅图9，第一磁碗侧壁322设有多个第一让位槽351，第一让位槽351自第一磁碗侧壁322远离第一磁碗底壁321一端朝靠近第一磁碗底壁321一端沿振动方向延伸；第二磁碗侧壁332设有多个第二让位槽352，第二让位槽352自第二磁碗侧壁332远离第二磁碗底壁331一端朝靠近第二磁碗底壁331一端沿振动方向延伸。一个第一让位槽351与一个磁钢第二让位槽352对应设置并形成一个避让孔35，避让孔35与通口141对应设置。
在本实施例中，第一连接部2313自第一固定部2311依次穿过避让孔35和通口141延伸到第二固定部2312，第二连接部2323自第三固定部2321依次穿过避让孔35和通口141延伸到第四固定部2322，一个第一连接部2313和一个第二连接部2323同时穿设于一个避让孔35和一个通口141。在其他实施例中，可以单独一个第一连接部2313或一个第二连接部2323穿设于一个避让孔35和一个通口141。
请参阅图4至图7、图10，第一连接部2313、第二连接部2323、避让孔35以及通口141均设有三个，三个第一连接部2313沿第一固定部2311周向等间距设置，三个第二连接部2323沿第三固定部2321周向等间距设置，三个避让孔35等间距设置，三个通口141等间距设置，一个通口141与一个避让孔35对应设置，一个第一连接部2313和一个第二连接部2323同时穿设于对应设置的一个通口141和一个避让孔35。
当音圈22振动时，带动第一连接部2313和第二连接部2323振动，通口141和避让孔35均沿振动方向延伸，使第一连接部2313和第二连接部2323有足够的运动空间。可以理解，第一让位槽351可以贯穿第一磁碗侧壁322，第二让位槽352可以贯穿第二磁碗侧壁332，通过该种方式，可以为第一连接部2313和第二连接部2323提供更充足的运动空间。
振膜组件21包括第一环形振膜211、第二环形振膜212以及设于第一环形振膜211与第二环形振膜212之间的环形球顶213，第一环形振膜211的内侧固定于内壁14远离第一底壁11的一端，第二环形振膜212的外侧固定于外壁13远离第二底壁12的一端；第一骨架231的第二固定部2312固定于环形球顶213。
环形球顶213包括球顶本体2131、与第一环形振膜211连接的第五固定部以及与第二环形振膜212连接的第六固定部2132，第五固定部设于球顶本体2131的内侧，第六固定部2132设于球顶本体2131的外侧，第二固定部2312固定于第五固定部。
在本实施例中，第二固定部2312形成第五固定部，环形球顶213与第一骨架231一体成型。通过该种设置方式，减少零件之间装配的配合误差，简化装配工序，提高生产效率。
以上仅所述是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
