应当理解，当磁路系统23中的主磁钢组件231在线圈3的驱动下带动发声单体2沿第二方向振动时，发声单体2为马达的振子，线圈3为马达定子，且磁路系统23可以驱动振动系统22沿第一方向振动发声，实现扬声器的发声功能，从而使得马达与扬声器共用一套磁路系统23，装配简单，成本更低，且更节省整机空间。
请参阅图1至图5，进一步地，磁路系统23还包括固定于盆架21内的第一极芯233，第一极芯233开设有与所述容纳腔2315正对设置的让位通槽2331，第一极芯233和振动系统22分别位于盆架21的相对两侧，主磁钢组件231分别固定连接于第一极芯233和振动系统22，副磁钢232固定于第一极芯233。具体的，第一极芯233可以为平板，第一极芯233的一侧板面与壳体1相接触，另一侧板面固定有主磁钢组件231和副磁钢232，且第一极芯233开设有与容纳腔2315正对设置的让位通槽2331，以保证第一极芯233不会干扰线圈3与壳体1之间的固定，同时，可以在发声单体2沿第二方向运动时避免第一极芯233与线圈3相碰撞。
在本发明实施例中，第一方向可以为Z向，第二方向可以为X向；主磁钢组件231和副磁钢232的充磁方式具有多种，使得磁路系统23产生的磁场强度存在差异，从而可以产生不同大小的驱动力，便于调节振动系统22沿第一方向的振动效果和发声单体2沿第二方向的振动效果。
请参阅图1、图2以及图3，在一些实施例中，主磁钢组件231包括固定于第一极芯233的第一磁环2311、固定连接于第一磁环2311的第二极芯2312、固定连接于第二极芯2312的第二磁环2313、以及分别固定连接于第二磁环2313和振动系统22的磁碗2314，第二极芯2312呈环形设置，第一磁环2311、第二极芯2312、以及第二磁环2313的内腔共同形成容纳腔2315。具体的，第一磁环2311的高度和副磁钢232的高度相等，即第一磁环2311和副磁钢232之间设有磁间隙；第一磁环2311的厚度大于第二磁环2313的厚度，第二磁环2313的厚度小于磁碗2314的厚度，有利于减小制造主磁钢组件231所消耗的材料，从而降低成本；磁碗2314盖合密封第二磁环2313的内腔，保证发声单体2的密封性，从而提升发声单体2的发声效果。根据实际需要，第一磁环2311的内腔、第二极芯2312的内腔、以及第二磁环2313的内腔的横截面大小相同，有利于保证主磁钢组件231对称设置。
请参阅图2和图3（图2中的箭头方向为充磁方向），在一个实施例中，多功能发声装置还包括固定于壳体1且位于容纳腔2315内的铁芯4，线圈3套设固定于铁芯4外侧；第一磁环2311的充磁方向朝向第一极芯233，第二磁环2313和副磁钢232的充磁方向均朝向振动系统22，磁碗2314的两端的充磁方向均朝向振动系统22，磁碗2314的中部区域的充磁方向朝向第一极芯233。具体的，铁芯4的一端穿过第一极芯233的让位通槽2331并固定于壳体1，另一端延伸至容纳腔2315内；线圈3的轴线延伸方向平行于磁碗2314的长度延伸防线，有利于线圈3提供驱动发声单体2沿第二方向运动的驱动力。应当理解，在本实施例中，铁芯4和线圈3共同作为马达定子。
请参阅图4以及图5（图4中的箭头方向为充磁方向），在一个实施例中，主磁钢组件231还包括收容于容纳腔2315内且两端分别固定于第一磁环2311内侧的磁体2316，线圈3套设于磁体2316的外侧；磁体2316自两端朝中部充磁，第一磁环2311的充磁方向朝向第一极芯233，第二磁环2313、磁碗2314以及副磁钢232的充磁方向均朝向振动系统22。具体的，磁体2316可以呈柱状，磁体2316为同级相对磁钢，线圈3的一侧穿过第一极芯233的让位通槽2331并与壳体1相接触，此时线圈3与壳体1之间可以通过打胶固定。应当理解，在本实施例中，仅线圈3作为马达的定子。
请参阅图1、图6以及图7，在一个实施例中，主磁钢组件231包括固定于第一极芯233的第一磁环2311、分别固定连接于振动系统22和第一磁环2311的磁碗2314、以及收容于容纳腔2315内且固定于第一极芯233的两第二极芯2312，第一磁环2311的内腔形成容纳腔2315，两第二极芯2312分布在第一磁环2311的相对两端，且第二极芯2312位于线圈3轴线的延伸方向上。具体的，第一磁环2311和副磁钢232之间形成磁间隙，第一磁环2311的高度高于副磁钢232的高度，且第一磁环2311的厚度大于磁碗2314的厚度，与其他实施例中主磁钢组件231设置多个磁环和多个极芯相比，本实施例中的主磁钢组件231仅设有一个磁环，简化了主磁钢组件231的装配工艺，同时可以降低主磁钢组件231的制造成本；磁碗2314盖合密封第一磁环2311的内腔，保证发声单体2的密封性，从而提升发声单体2的发声效果。
请参阅图6和图7（图6中的箭头方向为充磁方向），进一步地，多功能发声装置还包括固定于壳体1且位于容纳腔2315内的铁芯4，线圈3套设固定于铁芯4外侧；第一磁环2311在线圈3轴线的相对两侧的充磁方向相对设置，副磁钢232在线圈3轴线的相对两侧中的一侧的充磁方向朝向第一极芯233，另一侧朝向振动系统22。应当理解，本实施例中的铁芯4和线圈3的设置方式和前述实施例中的铁芯4和线圈3设置方式相同，在此不进行相关论述。
请参阅图2和图8，在一个实施例中，盆架21包括弹性连接于壳体1的主框架211、固定连接于主框架211远离壳体1的一侧的围合框212、以及固定于围合框212远离主框架211的一侧的上盖213，第一极芯233固定于主框架211，振动系统22与上盖213相连。具体的，主框架211开设安装通槽，第一极芯233固定于安装通槽内，围合框212用于围合密封主框架211，使得振动系统22、主磁钢组件231以及盆架21之间形成密封空间，有利于提升发声单体2的发声效果；主框架211的两端分别弹性连接于壳体1，便于发声单体2沿第二方向往复振动。
请参阅图2和图8，进一步地，围合框212设有缺口，多功能发声装置还包括分别固定连接于主框架211和壳体1且位于缺口内的弹性件5。具体的，围合框212设有两个缺口，弹性件5设有两个，且两弹性件5设置于线圈3的轴线延伸方向上，围合框212的缺口可以提供弹性件5足够的弹性形变空间，从而提升发声单体2沿第二方向的振动强度。
请参阅图2、图4以及图6，其中，弹性件5呈U型，弹性件5包括与主框架211固定连接的第一连接臂、固定连接于壳体1的第二连接臂、以及分别固定连接于第一连接臂和第二连接臂的弹力部，第一连接臂和第二连接臂之间具有间隙。当主磁钢组件231带动发声单体2沿第二方向运动时，第一连接臂朝靠近第二连接臂的方向运动，此时第一连接臂和第一连接臂之间的间隙变小；当弹性件5驱动发声单体2复原时，第一连接臂朝远离第二连接臂的方向运动，此时第一连接臂和第二连接臂之间的间隙变大。优选地，第一连接臂和第二连接臂的相对侧均固定有垫片，垫片可以缓冲第一连接臂和第二连接臂之间的碰撞，避免弹性件5因第一连接臂和第二连接臂之间的碰撞而损坏。根据实际需要，弹性件5也可以为V型和压缩弹簧型等，垫片可以采用泡沫、橡胶、硅胶的弹性材料。
请参阅图1、图2以及图3，在一个实施例中，振动系统22包括分别固定连接于盆架21和主磁钢组件231的振膜221，且振膜221和主磁钢组件231之间连接有密封环24；发声单体2还包括连接于振膜221且位于磁间隙内的音圈25，音圈25用于带动振膜221沿第一方向振动。具体的，振膜221包括固定连接于上盖213的外折环、连接于外折环的球顶、以及分别连接于球顶和磁碗2314的内折环，音圈25连接于球顶，密封环24设置于内折环和磁碗2314之间，以保证振膜221和主磁钢组件231之间密封连接。当磁路系统23驱动音圈25振动时，音圈25带动球顶、内折环和外折环振动，从而使得振膜221振动发声。
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。
