Description

混合扬声器单体以及扬声器模组 技术领域
本发明涉及电声转换技术领域，更具体地，涉及一种混合扬声器单体以及应用了该单体的扬声器模组。
背景技术
现有的扬声器包括动圈式扬声器和动铁式扬声器。其中，动圈式扬声器包括磁路系统和振动系统。磁路系统包括T铁/或者U铁、永磁铁、华司等。振动系统包括振膜、音圈和DOME。动圈式扬声器的中频效果和低频效果较好，但高频效果差。
动铁式扬声器也包括磁路系统和振动系统。其中，磁路系统包括电枢、线圈、永磁铁和磁轭等，永磁铁和磁轭连接，电枢穿过线圈和永磁铁。电枢被交变的线圈极化产生磁场，与永磁铁相互作用以振动发声。动铁式扬声器的高频效果好，但中低频效果差。
因此，需要提供一种新的方案以提高扬声器高、中、低频效果。

根据本发明的另一个方面，提供了一种扬声器模组。该模组包括本发明提供的所述混合扬声器单体。
本发明的发明人发现，在现有技术中，现有的扬声器单体都是单磁路系统，无法同时得到良好的高频、中频、低频效果。因此，本发明所要实现的技术任务或者所要解决的技术问题是本领域技术人员从未想到的或者没有预期到的，故本发明是一种新的技术方案。
该混合扬声器单体具有两个磁路系统，两个磁路系统分别对振膜和膜片进行驱动，扩展了扬声器单体的频响范围。
此外，在动圈发生单元中设置动铁发声单元。膜片和振膜连接在一起，并且膜片与第二磁路系统通过传动杆连接，传动杆能够支撑膜片。通过这种方式，能够降低高频的分割振动，提高了振膜和膜片的高频延展性，使得扬声器单体的高频性能优良。
此外，由于该混合扬声器单体包括动圈发声单元和动铁发声单元，因此具有优良的低频、中频和高频性能。
此外，第二磁路系统设置在芯柱的容纳腔中，膜片与振膜连接，故动铁发声单元不占用动圈发生单元外部的空间，使得该混合扬声器单体体积小，顺应了电子设备小型化、轻薄化的发展趋势。

应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
根据本发明的实施例，提供了一种混合扬声器单体。该单体包括动圈发声单元和动铁发声单元。动圈发声单元包括振动系统和与振动系统配合的第一磁路系统。振动系统包括振膜12，第一磁路系统包括T铁18。
在本发明实施例中，T铁18的芯柱具有容纳腔19。动铁发声单元包括第二磁路系统15、传动杆25和膜片11。第二磁路系统15被设置在容纳腔19中。传动杆25的一端与第二磁路系统15连接并且另一端与膜片11连接。膜片11与振膜12连接。例如，二者位于同一平面，这样便于连接并且膜片11与振膜12的振动方向相同，振动更均衡，偏振小。
例如，在使用时，电子设备的主控芯片与混合扬声器单体的线圈22和音圈14导通。两个发声单元同时振动发声。
该混合扬声器单体具有两个磁路系统，两个磁路系统分别对振膜12和膜片11进行驱动，扩展了扬声器单体的频响范围。
此外，在动圈发生单元中设置动铁发声单元。膜片11和振膜12连接在一起，并且膜片11与第二磁路系统15通过传动杆25连接，传动杆25能够支撑膜片11。通过这种方式，能够降低振膜和膜片的高频的分割振动，提高了振膜12和膜片11的高频延展性，使得扬声器单体的高频性能优良。
此外，由于该混合扬声器单体包括动圈发声单元和动铁发声单元，因此具有优良的低频、中频和高频性能。
此外，如图3所示，第二磁路系统15设置在芯柱的容纳腔19中，膜片11与振膜12连接，故动铁发声单元不占用动圈发生单元外部的空间，使得该混合扬声器单体体积小，顺应了电子设备小型化、轻薄化的发展趋势。
图1是根据本发明的一个实施例的混合扬声器单体的分解图。图2是根据本发明的一个实施例的混合扬声器单体的剖视图。
如图1-2所示，在该实施例中，振动系统包括音圈14和振膜12。振膜12和音圈14连接。例如，振膜12可以是平面振膜12或者折环振膜12。振膜12为折环振膜12。折环振膜12包括中心部、围绕中心部设置的折环部27和围绕折环部27设置的固定部。这种振膜12具有振幅大、频率范围广、使用寿命长的特点。
可选的是，振膜12为圆形、方形或者跑道形，以适应不同形状的扬声器单体。
当然，振膜12也可以是平面形振膜12。膜片11可以根据需要设置在 平面形振膜12的任意部位。优选的是，膜片11设置在平面形振膜12的中心位置，以保证振动的均衡。
第一磁路系统包括T铁18、第一永磁体17和华司16。例如，第一永磁体17为铁氧体磁铁或者钕铁硼磁铁。T铁18包括芯柱和与芯柱连接的基底。第一永磁体17为环形磁铁，并且围绕芯柱设置。华司16设置在第一永磁体17上。芯柱与第一永磁体17之间以及华司16与第一永磁体17之间形成磁间隙。
在该实施例中，振膜12的固定部与铜环13连接，铜环13设置在第一永磁体17上。铜环13起到支撑的作用，以使振动系统悬置在磁路系统上方。音圈14插入磁间隙中。
例如，由芯柱的侧壁20和基底围合形成容纳腔19。第二磁路系统15设置在容纳腔19内。第二磁路系统15包括第二永磁体23、线圈22、磁轭24和电枢26。第二永磁体23为铁氧体磁铁或者钕铁硼磁铁。
例如，磁轭24为环状，磁轭24被固定在基底上。第二永磁体23包括相对设置的两个条形磁铁。两个条形磁铁被设置在磁轭24内，二者之间形成均匀的磁场。线圈22与磁轭24并列地设置在基底上，线圈22与磁轭24之间具有间隙。
例如，电枢26为L形。电枢26的一条边的端部固定在基底上，以使另一条边悬置在容纳腔19中。悬置的边穿过线圈22内部到达磁场中。电枢26为导磁性材料，例如SUS-430等。
传动杆25的一端与悬置的边连接。例如，传动杆25从线圈22与磁轭24之间的间隙穿出，并且另一端与膜片11连接。
在工作时，线圈22通交流电后在内部产生交变磁场，交变磁场将电枢26磁化。磁化后的电枢26在磁场中发生振动。电枢26带动传动杆25振动。传动杆25带动膜片11振动以发声。
在一个例子中，膜片11被设置在中心部。这样能够使振膜12和膜片11的振动更均衡。例如，通过粘结剂将膜片11粘接在中心部。
优选的是，膜片11与振膜12一体成型。例如，通过注塑的方式将膜片11与振膜12一体注塑成型。通过这种方式，膜片11与振膜12的连接 强度和结构强度更高，进一步降低了膜片11的分割振动。此外，膜片11和振膜12的顺性更好，振动效果良好。
可选的是，振膜12和膜片11由热塑性材料制作而成。例如，这种材料可以是但不局限于热塑性聚氨酯弹性体材料(Thermoplastic polyurethanes,TPU)膜层、聚醚醚酮材料(polyetheretherketone,PEEK)膜层、热塑性弹性体材料(Thermoplastic Elastomer,TPE)膜层、聚丙烯材料膜层(Polypropylene，PP)、合成纤维材料膜层等。
在一个例子中，膜片11为弧面结构。弧面结构具有更高的弹性，并且结构强度更高。这样，混合扬声器单体的高频效果更好。
优选的是，膜片11为向内凹陷的弧面结构，即，在安装时弧面靠近第二磁路系统15。这样，当水滴落在膜片11上时，膜片11不会被水滴压变形，能够保持良好的振动效果。这种结构更适用于防水型扬声器。
进一步地，振膜12的折环部27为向内凹陷型，即，在安装时折环部27靠近第一磁路系统。这样，当水滴落在折环上时，折环部27不会被水滴压变形，能够保持良好的振动效果。这种结构更适用于防水型扬声器。
在一个例子中，混合扬声器单体还包括设置在T铁18上的PCB21(Printed Circuit Board，印刷线路板)。PCB21与振动系统的音圈14和第二磁路系统15的线圈22连接。例如，如图2所示，PCB21被设置在T铁18的基底的外侧，以节省内部空间。音圈14和线圈22的引线与PCB21连接。PCB21与电子设备的主控芯片连接。通过设置方式，能够使混合扬声器单体的信号连接更稳定。
根据本发明的另一个实施例，提供了一种扬声器模组。该扬声器模组包括本发明提供的混合扬声器单体。
例如，扬声器模组包括外壳。外壳的内部具有腔体。混合扬声器单体被设置在腔体内，以将腔体分隔为前声腔和后声腔。后声腔用于调节低频效果。振膜12和膜片11的面向前声腔。外壳还具有出声孔。出声孔用于连通前声腔与外部空间。
该扬声器模组具有良好的低频、中频和高频效果，并且频响范围宽。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是 本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
