Description

一种扬声器 技术领域
本实用新型涉及一种声电能转换器，尤其涉及一种扬声器。
 背景技术
装配完成的扬声器通常包括前后两个音腔，前腔为振膜到出音孔之间的收容空间，振膜的另一侧的收容空间为后腔。而扬声器的发声原理是：高频电流通过磁路系统的音圈产生磁场，驱动音圈振动，从而带动振膜振动,再通过出音孔将声音传递出去。
通常，扬声器为使用前腔发音的结构，且振动系统的位置远离后腔，磁路系统的位置靠近后腔，当高频电流通过音圈产生磁场时，振动系统的音圈振动所产生的热量只能透过振膜散发出去，不能达到较好的散热效果。
因此，有必要提供一种扬声器结构，提高散热效果。
 技术问题

附图说明

图2为本实用新型实施例提供的扬声器的立体结构分解图；
图3为图1中A-A方向的剖面图；
图4为本实用新型实施例提供的磁路系统的立体结构示意图。
 本发明的实施方式
下面结合附图和实施方式对本实用新型作进一步说明。
请参阅图1-图4，本实用新型实施例首先示出了扬声器100的立体结构，其包括振动系统10、磁路系统20、盆架30和隔层40。其中，盆架30为具有收容空间的结构，振动系统10、磁路系统20和隔层40均收容在此收容空间中，则图1中仅示出了盆架30的外部结构。
本实用新型实施例还补充了上述扬声器100分解后的立体结构，以说明扬声器100所包括的振动系统10、磁路系统20、盆架30、隔层40以及振动系统10和磁路系统20中各部件的详细结构。
振动系统10包括振膜11和驱动振膜11振动的音圈12。磁路系统20包括磁碗21和组配于磁碗21内并具有磁间隙23的磁钢组件22。磁钢组件22包括居中设置的主磁钢221和设于主磁钢221周围并与主磁钢221形成所述磁间隙23的副磁钢222。
其中，磁间隙23用于供音圈12插设在其中，当磁路系统20为音圈12提供驱动时，音圈12振动，从而带动振膜11振动产生声音。
其中，振膜11固定在盆架30上，并将盆架30中的收容空间分隔为前腔和后腔，如图1和图2所示，盆架30包括上盖31和下盖32，上盖31与振膜11形成前腔，下盖32与振膜11形成后腔，上盖31和下盖32盖接后，构成盆架30的收容空间，而振动系统10、磁路系统20和隔层40均收容在盆架30的收容空间中。则振膜11也可视为盆架30中上盖31和下盖32 的划分，而隔层40设置在上盖32。
在一个实施例中，隔层40为透气结构，包括通孔41和覆盖通孔41的透气膜42，图2中以中空边缘表示通孔位置，以中空部分表示透气膜位置。
在本实用新型实施例中，下盖32上设有灌粉口321。
请参阅图3，本实用新型实施例还通过图1中A-A方向的剖面图，说明装配后的扬声器100的内部结构。
结合图2和图3，可见，本实用新型实施例中，振膜11将盆架30中的收容空间分隔为前腔和后腔后，振动系统10和磁路系统20均设于前腔，隔层40设置于上盖32，则隔层40位于后腔，并且，磁碗21和磁钢组件22均设于远离后腔的位置，磁碗21和主磁钢221上设有至少一个将前腔与外界连通的出声孔24。其中，由图2所示的振动系统10和磁路系统20的结构可知，音圈12插设在磁钢22的磁间隙23中，则出声孔24为扬声器100的音圈12提供了一个直接散热路径，其散热过程可以为：音圈12振动过程中产生的热量先向音圈12中间延伸，然后通过出声孔24直接散发至外界，期间不再经过扬声器100中的其他结构，因此具有良好的散热效果。
在一个实施例中，振膜11包括球顶部111、自所述球顶部111向外延伸的折环部112以及自所述折环部112向外延伸的固定部113，所述固定部夹设于所述上盖31和所述隔层40之间。
请继续参阅图2和图3，本实用新型实施例还对振动系统11的详细结构进行说明，以分析振动系统11和盆架30中上盖31及下盖32之间的连接关系。如图2和图3所示，振动系统11还包括球顶13，球顶13位于前腔，且贴设于振膜11上。由于当磁路系统20为音圈12提供驱动时，音圈12振动，将带动振膜11振动，因此，音圈12与振膜11以及球顶13之间存在连接关系，则如图2和图3所示，球顶13和所述音圈12之间设有固定环14，分别与所述球顶13和所述音圈12固定连接。
请参阅图4，本实用新型实施例还单独示出了前腔中，磁路系统20的立体结构，以说明出声孔24的详细结构，可以理解的是，图4中仅示出了一个出声孔24，且图4中示出的出声孔24示例性地表现为矩形，其沿所述振膜11的振动方向在所述振膜11上的投影也呈矩形。
请继续参阅图2和图3，出声孔24同时设置在磁碗21和主磁钢221中，则本实用新型实施例中，出声孔24包括设于磁碗21上的第一出声孔241，和设于主磁钢221上的第二出声孔242，第一出声孔241与第二出声孔242沿振膜11的振动方向在振膜11上的投影重合。
由图1至图4所示的扬声器100的结构可知，本实用新型实施例中，扬声器100中的层级结构为：磁路系统20→振动系统10(除振膜11)→振膜11→隔层40，其中，磁路系统20和振动系统10所处位置为前腔，磁路系统20具有将前腔与外界连通的出声孔24。
而传统的扬声器结构中，其层级结构应为：振动系统→磁路系统→隔层。
因此，本实用新型实施例提供的扬声器结构与传统的扬声器结构相比，调换了振动系统和磁路系统的位置，本实用新型实施例提供的扬声器工作时，音圈振动过程中产生的热量可以从磁碗的发声孔传递到外部，而传统的扬声器结构中，音圈振动过程产生的热量需要穿过振膜后再传递到外部，相比之下，本实用新型实施例提供的扬声器结构具有更好的散热途径，能够有效解决音圈振动过程中的散热问题，提高散热效果。
综上所述，本实用新型实施例提供了一种新的扬声器结构，其包括具有收容空间的盆架，和收容与收容空间内的振动系统、磁路系统和隔层，振动系统中的振膜固定在盆架上，并将收容空间分隔为前腔和后腔，振动系统和磁路系统均设于前腔，且磁路系统相对于振动系统来说，其位置更加远离后腔，即本实用新型中调换了传统扬声器中振动系统和磁路系统的位置，同时，磁路系统中，磁碗和主磁钢上设有至少一个将前腔与外界连通的出声孔，而音圈插设在由主磁钢和副磁钢形成的磁间隙中，使得音圈可以直接通过出声孔散热，且期间不再经过扬声器的其他结构，因此有效解决了音圈振动过程中的散热问题，提高散热效果。
以上所述的仅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。
