Description

高音扬声器及其振动结构和倒凹振膜以及制造方法和音效再现方法 技术领域
本发明涉及一扬声器领域,尤其涉及一高音扬声器及其振动结构和倒凹振膜以及制造方法和音效再现方法。
背景技术
声音,是通过物质的振动产生声波。当声波通过任何物质去传播形成一振动频率,且这种振动频率在20Hz到20kHz之间时是人类耳朵可识别的声音。现有常见的声效装置,例如扬声器或喇叭,通常是一种把电信号转换成声信号的换能器件或电子组件。所述声效装置通常包括一扬声器框架,并由所述扬声器框架支撑的一振膜,与所述振膜耦联的一音圈,以及与所述音圈电磁感应的一磁回单元,从而所述磁回单元诱导所述音圈往复运动去驱使所述振膜振动,进而藉由所述振膜以鼓动空气的方式展现声音。也就是说,将所述振膜安装在所述扬声器框架的一开口处,其中当电磁地诱导所述音圈往复运动时,相应地所述音圈驱动了所述振膜来回振动,并在所述振膜来回振动时以鼓动空气的方式产生声音。
在传统的扬声器通常还包括有一定心支片,其用于支撑所述音圈和所述振膜的结合部位,以限制所述音圈和所述振膜的运动方向。由于所述定心支片较大的弹力,因此在作动时常导致所述振膜在往复运动时的运动速度是不均匀的。而且所述定心支片常使得所述音圈以非线性的方式运动。因此一旦所述音圈没有对准所述音圈的中心轴运动而出现偏斜,所述音圈可能会刮碰到所述扬声器的内侧,从而使所述音圈的保护涂层将会逐渐地受到损坏。进一步地说,在传统扬声器中,所述定心支片会导致所述音圈偏离其轴向位移的方向产生较大的左右晃动和位移,从而导致声音不纯。另外,在传统的扬声器中因为需要设置所述定心支片,因此,在所述音圈和所述扬声器框架之间需要提供较大的空间以供容纳所述定心支片,这导致所述音圈的外壁到所述扬声器框架的内壁之间的距离比较大,进而限制了扬声器的小型化。
另外,传统的高音扬声器还包括有一悬边,其连接于所述扬声器框架和所述振膜之间,主要是因为所述振膜的圆边与所述扬声器框架不是直接接触的。特别地是,所述弹性悬边对频率响应也有不同的影响,除了型式结构外,其材质的选用也是一门学问,常见的有布、泡棉、和橡皮等,其中泡棉的缺点是容易腐烂,布则是需要结合高分子材料来进一步的加强特性,制造工艺耗时耗力,而橡皮悬边就没有这些缺点,而且它的阻尼特性也好,但橡皮悬边的单体价格较高。这些扬声器的所述弹性悬边不管选用何种材质,其组合时都是经由胶粘的方式,即将所述振膜和所述弹性悬边以胶粘在一起以及将所述弹性悬边和所述扬声器框架以胶粘在一起,这样的制程很麻烦又不稳定,特别是在布的悬边,每一道工序都要胶水粘合。另外,在传统扬声器的高音部分是依靠所述振膜的特殊材质去增加高频的延伸度,这样的缺点是制程复杂以及成本高昂。更为重要的是,胶粘所述振膜和所述弹性悬边以及胶粘所述弹性悬边和所述扬声器框架的方式,导致所述弹性悬边容易从所述振膜和/或所述扬声器框架上脱落或者松动而导致扬声器的音质受到影响,从而影响扬声器的可靠性和稳定性。众所周知 的是,对于高音扬声器来说,所述振膜的来回振动频率比较高,长期的且高频的来回振动容易导致所述弹性悬边和所述振膜以及所述弹性悬边和所述扬声器依靠胶水保证的连接稳定性变差。
高音扬声器是指能够产生高音的扬声器,其工作频率通常在20kHz以上,现有的高音扬声器的振膜为上凸式振膜,例如半球形振膜,通常认为,带有上凸式振膜的高音扬声器不仅便于高频扩散,而且振膜强度更大,在振动的过程中不易变形而导致声音失真。但是带有上凸式振膜的高音扬声器具有诸多的缺陷。具体地说,带有上凸式振膜的高音扬声器的振膜的中部是向上凸起的,而高音扬声器是依靠振膜来回鼓动空气而产生声音的,这导致高音扬声器产生的声波是以扩散的方式向四周扩散的,而对于一些高音扬声器来说,尤其是对应用于头戴式音效装置的高音扬声器来说,其往往需要汇聚高音,显然,现有的带有上凸式振膜的高音扬声器无法汇聚高音。

具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的较佳实施例只作为举例,本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
本领域技术人员应理解的是,在本发明的揭露中,术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系是基于附图所示的方位或位置关系,其仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或组件必须具有特定的方位、以特定的方位构造和操作,因此上述术语不能理解为对本发明的限制。
可以理解的是,术语“一”应理解为“至少一”或“一个或多个”,即在一个实施例中,一个组件的数量可以为一个,而在另外的实施例中,该组件的数量可以为多个,术语“一”不能理解为对数量的限制。
另外,众所周知的是,扬声器频率在2560HZ至5120HZ频段为高音,5120HZ以上频段为超高音。本发明的高音扬声器适合于能提供2560HZ以上频段这样的高音频段音效,从而定义为所述高音扬声器。
如图1至图5所示,是根据本发明的一个第一较佳实施例的一高音扬声器,其振膜结构和制程形成高质量的所述高音扬声器,除降低制造成本外,还减化制程,并提高制程品质。所述高音扬声器包括一扬声器壳体10,一振动单元20,一音圈30,以及一磁回单元40。所述振动单元20,所述音圈30以及所述磁回单元40容纳于所述扬声器壳体10。进一步地说,所述振动单元20设置于所述扬声器壳体10,所述音圈30的一端连接于所述振动单元20,所述音圈30的另一端与所述磁回单元40耦联。也就是说,所述音圈30位于所述振动单元20和所述磁回单元40之间,所述扬声器壳体10将所述振动单元20,所述音圈30以及所述磁回单元40容纳其中。值得一提的是,所述音圈30在所述磁回单元40的电磁驱动力的作用下来回运动,从而藉由所述音圈30带动所述振动单元20沿着其轴向方向来回运动,以使所述振动单元20鼓动所述高音扬声器内和周围的空气而产生声音。
在本发明的这个较佳实施例中,所述扬声器壳体10包括一面板11和一后盖12,所述面板11与所述后盖12相接合,将所述振动单元20,所述音圈30以及所述磁回单元40容纳其中。换言之,所述振动单元20、所述音圈30和所述磁回单元40被保持在形成于所述面板11和所述后盖12之间的空间。值得一提的是,所述面板11与所述后盖12可以通过各种方式组合在一起,例如互相搭配的锁扣组件、螺纹组件、热熔接、超声波接合等。以本实施例的所述高音扬声器竖直放置为例,所述扬声器壳体10的所述面板11可以是上壳体,所述后盖12可以是下壳体。
在本发明的这个较佳实施例中,所述振动单元20包括一倒凹振膜21和一弹性悬边22,其中所述弹性悬边22一体地连接于所述倒凹振膜21。优选地,所述弹性悬边22一体地连接于所述倒凹振膜21和所述面板11。进一步地说,所述弹性悬边22采用一体射出工艺,并在工艺中同时与所述倒凹振膜21和所述面板11相连接。值得一提的,所述弹性悬边22在一体射出工艺时,同时将一体地连接于所述面板11。换言之,经由一体射出工艺将所述弹性悬边22、所述倒凹振膜21以及所述面板11结合成一体化零件,以形成所述高音扬声器的一振动结构200,其中所述振动结构200是一体化的振动结构。可以理解的是,在本发明的所述高音扬声器中,因为所述振动结构200是一体化的振动结构,从而有利于保证所述弹性悬边22与所述倒凹振膜21在各个结合位置的一致性,通过这样的方式,能够进一步增强所述高音扬声器的高音效果,并且所述弹性悬边22保证所述倒凹振膜21在沿着所述高音扬声器的轴向方向来回振动的过程中不会产生偏斜。可以理解的,所述弹性悬边22通过嵌入射出工艺制成。也就是说,将所述面板11和所述倒凹振膜21放入制作模具中,然后将制作所述弹性悬边22的材料以液体形态注入,所述弹性悬边22的材料附着在所述面板11和所述倒凹振膜21,冷却固化后在所述面板11和所述倒凹振膜21之间所述弹性悬边21,便能起到固定所述面板11和所述倒凹振膜21的作用,并使成为一体化零件。
另外,所述音圈30的一端连接于所述振动单元20的所述倒凹振膜21,所述音圈30的另一端与所述磁回单元40耦联,这样所述音圈30在所述磁回单元40的电磁驱动力的作用下来回运动,从而带动所述振动单元20的所述倒凹振膜21和所述弹性悬边22沿着其轴向方向来回运动而使所述高音扬声器提供高频的声音。可以理解的,所述弹性悬边22将所述倒凹振膜21的运动限制在其轴向方向。相应地,所述倒凹振膜21只沿着其轴向方向运动,而不会产生偏移,通过这样的方式,能够保证所述高音扬声器产生的高音的纯粹性。
值得一提的,本发明的这个所述高音扬声器中,没有传统扬声器的定心支片(弹波)。本领域人员可以理解的是,本发明的所述倒凹振膜21和所述弹性悬边22也可以应用在其他各种扬声器或声效装置中,包括传统的具有弹波的扬声器。换言之,本发明的所述振动结构200可以被应用于各种扬声器或者声效装置中,包括传统的具有弹波的扬声器。
在本发明的这个较佳实施例中,所述倒凹振膜21为下凹弧形,其中相对所述高音扬声器的尺寸设定一弧形高度H和一弧形弧度R的预定参数,所述高音扬声器的直径适合在8-38毫米(MM)的范围,所述弧形高度H的范围值为5-7毫米(MM),所述弧形弧度R的范围值为15-20毫米(MM)。优选地,所述高音扬声器的直径适合在10-20毫米。更优选地,所述高音扬声器的直径适合在10-15毫米机或者15-20毫米。所述弧形高度H的范围值为5.5-6.5毫米。所述弧形弧度R的范围值为16-18毫米,例如17毫米。
可以理解的是,经由本发明这样的结构,如图11所示,横坐标是频率(单位为HZ),纵坐标为分贝(单位dBSPL),经美国Linearx System公司的LMS电声测试系统的测试,本发明的所述高音扬声器的高频能够延展到40KHZ的超高频,这样的高音频段表现,能够显着地加强本发明的扬声器的高音效果。
本发明的所述倒凹振膜21的所述弧形高度H被选择为5-7毫米的范围,同时,所述倒凹振膜21的所述弧形弧度R被选择为15-20毫米的范围,使得带有所述倒凹振膜21的所述高音扬声器能够产生2560Hz以上高频的高音,甚至所述带有所述倒凹振膜21的所述高音扬声器能够产生40kHz以上高频的高音,如附图11示出的测试结果,这是现有技术的高音扬声器意料不到的。正如本专利申请在背景技术部分阐述的那样,本领域技术人员认为,现有技术的高音扬声器只有将振膜的结构在中部设置为凸起的方式才能够使高音扬声器产生高音,并且现有技术的高音扬声器的高音的高频普遍在20kHz-2560Hz左右,而在本发明的所述高音扬声器中,所述倒凹振膜21呈内凹的形状,并且因为所述倒凹振膜21的所述弧形高度H和所述弧形弧度R被选择后,所述高音扬声器能够产生高品质的且高频在2560Hz以上的高频的高音,甚至能够产生高品质的且高频在40kHz以上的超高频的高音,这克服了本领域技术人员的技术偏见,并且本发明的所述高音扬声器具有现有技术的高音扬声器意料之外的技术效果。
另外,本发明的所述高音扬声器的所述倒凹振膜21呈内凹状,从而所述高音扬声器产生的高音能够被汇聚,相对于现有技术的采用具有凸起结构的振膜的的高音扬声器来说,本发明的所述高音扬声器产生的高音能够因为所述倒凹振膜21的结构而被汇聚,从而使得所述高音扬声器的高音能够更为集中,以扩大所述高音扬声器的应用范围。例如,本发明的所述高音扬声器适于被应用于头戴式音效装置,例如耳机。
更具体地,所述倒凹振膜21具有一上平面211和一下凹弧面212,其中所述上平面211呈圆形环绕于所述下凹弧面212的四周,并且所述弹性悬边22一体地连接于所述倒凹振膜21的所述上平面211。所述下凹弧面212从所述上平面211呈圆弧向下形成。值得一提的是,所述下凹弧面212位于所述音圈30内。换言之,所述音圈30可以环绕所述下凹弧面212的至少一部分。另外,所述倒凹振膜21是金属材质所制,例如但不限于铝材,也就是说,所述倒凹振膜21是金属振膜,如铝膜,通过这样的方式,能够增强所述倒凹振膜21的强度,以在所述倒凹振膜21被驱动的过程中防止所述倒凹振膜21产生变形,从而保证声音的纯粹 性。在所述弹性悬边22制成时同将所述倒凹振膜21容纳连接成一体。可以理解的是,在本发明的所述高音扬声器中,所述倒凹振膜21的所述弧形高度H为所述下凹弧面212的弧形高度,和所述倒凹振膜21的所述弧形弧度R为所述下凹弧面212的弧形弧度。
在本发明的这个较佳实施例中,所述弹性悬边22其由弹性材料制成,并且设置在所述倒凹振膜21和所述面板11之间,例如所述弹性悬边22可以是但不限于橡胶悬边。在本发明的所述高音扬声器中,所述弹性悬边22以一体地结合于所述倒凹振膜21和所述扬声器框架10的所述面板11的方式被设置在所述倒凹振膜21和所述面板11之间。具体地,本发明的所述弹性悬边22包括内悬边部分和外悬边部分,所述内悬边部分和所述外悬边部分可以一体成形,并且都可以呈环形地围绕在所述倒凹振膜21的周围,沿着横截面的方向,所述内悬边部分和所述外悬边部分成型在一起并形成平面、褶皱形、拱形、或波形结构。在这个实施例中,所述弹性悬边22的所述内悬边部分和所述外悬边部分一体地连接并且形成平面结构。值得一提的是,所述弹性悬边22和所述倒凹振膜21可以由不同材料制成,例如所述弹性悬边22可以使用相对于所述倒凹振膜21较软的材料制成。这样,所述弹性悬边22和所述倒凹振膜21的软硬材料结合,可更有效地防止拉扯应力的快速传递,并使所述倒凹振膜21更有规律地振动。
所述弹性悬边22包括一悬边主体221和互相间隔地并且沿着环形方向设置的多个弹肋222,各个所述弹肋222一体地并且凸起地延伸于所述弹性悬边主体211。相邻两个所述弹肋222互相间隔地设置,并且多个所述弹肋222呈辐射状地均匀地排列,以起到将所述弹性悬边22的位移方向限制在其轴向方向上的作用。在另外的示例中,各个所述弹肋222也可以一体地并且凹陷地延伸于所述悬边主体211。而在本发明的另一个示例中,一部分的所述弹肋222可以凸起地延伸,而另一部分所述弹肋222可以凹陷地延伸,例如,邻近凸起的所述弹肋222的所述弹肋222是凹陷的。具体地,当所述弹性悬边22将要产生一个预定方向的偏离轴向的位移时,位于相反方向的所述弹肋222就会起到限制作用,防止所述弹性悬边22的进一步偏移。另外,所述弹肋222所形成的凸起的形状可以不受限制,相应的在另一侧形成的凹槽也可以具有各种形状。例如,所述弹肋222的横截面可以呈弓形、拱形、三角形、四边形、多边形、半圆形、半椭圆形、倒置的U形、倒置的V形等。
值得一提的,当所述弹性悬边22由所述内悬边部分和所述外悬边部分形成褶皱形、拱形、或波形结构,其中多个所述弹肋222可根据需求辐射状地均匀地排列设置于所述内悬边部分或所述外悬边部分,或者同时辐射状地均匀地排列设置于所述内悬边部分和所述外悬边部分上,这不为本发明的限制。本发明这个实施例中,这些所述弹肋222呈螺旋状地布置,给所述倒凹振膜21提供朝向所述高音扬声器的中心轴的向心力,从而使得所述倒凹振膜21的振动方向限制在所述高音扬声器的轴向方向。
值得一提的,本发明的所述高音扬声器无设置定心支片,但不影响其音质,可以说是通过所述弹肋222的限位作用,使得所述倒凹振膜21只在所述高音扬声器的轴向方向上产生来回位移,这样防止所述倒凹振膜21鼓动空气而产生声音的同时产生杂音。而且,因为所述高音扬声器无定心支片的结构,使得所述音圈30离所述扬声器壳体10的内表面的距离得以缩短,从而可以形成更紧凑的结构。另外,因为所述音圈30与所述扬声器壳体10之间距离得以缩短,所述音圈30偏离所述高音扬声器的轴向方向的活动空间相应地减小,这样更 有效地防止所述音圈30以较大的辐度偏离所述高音扬声器的轴向方向晃动。另外,所述高音扬声器不需要被设置定心支片,从而有利于降低所述高音扬声器的制造成本和制造难度,并且有利于所述高音扬声器的小型化。
在本发明的这个较佳实施例中,所述磁回单元40包括一磁保护套41,一永磁体42,以及至少一导磁体43。所述永磁体42位于所述导磁体43的下方,并放置于所述磁保护套41内,且所述永磁体42和所述磁保护套41之间形成一磁隙44。换言之,所述永磁体42和所述导磁体43以所述永磁体42位于所述导磁体43的下部的方式被设置于所述磁保护套41内。所述音圈30的一端连接于所述振动单元20的所述倒凹振膜21,所述音圈30的另一端与所述磁回单元40的所述磁隙44耦联。所述磁保护套41可以具有传统的U铁的结构,所述导磁体43可以具有传统的极片的结构。所述磁保护套41与所述导磁体43将所述永磁体42的磁力线导引至所述磁隙44处,从而使所述磁回单元40能与设置在所述磁隙44的所述音圈30相互作用。也就是说,所述磁保护套41,所述永磁体42以及所述导磁体43一起形成磁场回路,以与所述音圈30协同作用产生振动。也就是说,所述音圈30的一个端部能够被连接于所述倒凹振膜21,和所述音圈30的另一个端部延伸至所述磁回单元40的所述磁隙44,以使所述音圈30与所述磁回单元40能够磁性地交流,从而所述磁回单元40能够驱动所述音圈30来回运行。
在本发明的这个较佳实施例中,所述永磁体42可以是各种磁石,磁铁,或磁钢,如可以是金属系磁石、铁氧铁磁石、稀土类磁石等。在本发明的这个较佳实施例中,所述永磁体42可以是钕铁硼磁石。其在所述磁回单元40中提供磁能,并形成磁场回路以提供所述磁隙44。

值得一提的是,相对于传统的通过胶水粘结所述弹性悬边22B的所述内侧连接边224B和所述倒凹振膜21B以及粘结所述弹性悬边22B的所述外侧连接边225B和所述面板11B的方式来说,所述弹性悬边22B不需要被预先提供,从而能够减少所述高音扬声器的制作流程和降低所述高音扬声器的工艺难度,并且能够有效地降低所述高音扬声器的制作成本。更为重要的是,在所述弹性悬边22B成型的过程中,所述弹性悬边22B能够以所述弹性悬边22B的所述内侧连接边224B一体地结合于所述倒凹振膜21B和所述外侧连接边225B一体地结合于所述面板11B的方式被保持在所述面板11B和所述倒凹振膜21B之间,以保证所述弹性悬边22B的所述内侧连接边224B与所述倒凹振膜21B的各个结合位置的一致性和保证所述弹性悬边22B的所述外侧连接边225B与所述面板11B的各个结合位置的一致性,从而在所述倒凹振膜21B被所述音圈30B驱动而来回振动的过程中,所述弹性悬边22B能够保证所述倒凹振膜21B仅沿着所述高音扬声器的轴向方向来回振动,而避免所述倒凹振膜21B偏离所述高音扬声器的轴向方向的不良现象出现,从而保证所述高音扬声器的高音音效。
另外,在所述弹性悬边22B成型的过程中,所述弹性悬边22B能够以所述弹性悬边22B 的所述内侧连接边224B一体地结合于所述倒凹振膜21B和所述外侧连接边225B一体地结合于所述面板11B的方式被保持在所述面板11B和所述倒凹振膜21B之间,从而所述弹性悬边22B的所述内侧连接边224B能够可靠地结合于所述倒凹振膜21B,和所述弹性悬边22B的所述外侧连接边225B能够可靠地结合于所述面板11B,从而在所述倒凹振膜21B被所述音圈30B驱动而来回振动的过程中,能够避免所述弹性悬边22B的所述内侧连接边224B从所述倒凹振膜21B和/或所述弹性悬边22B的所述外侧连接边225B从所述面板11B上脱落或者松动,从而保证所述高音扬声器在被使用时的可靠性。
优选地,所述面板11B具有至少一接合槽112B,在附图15示出的阶段,所述面板11B的所述接合槽112B朝向所述成型模具90B的所述上模具92B,并且所述面板11B的所述接合槽112B连通所述成型空间93B,从而在附图16示出的阶段,被加入所述成型空间93B的所述成型材料100B会流入并填充至所述面板11B的所述接合槽112B,从而在所述成型材料100B固化后,所述弹性悬边22B的所述外侧连接边225B的至少一部分被容纳于所述面板11B的所述接合槽112B,通过这样的方式,所述弹性悬边22B的所述外侧连接边225B能够更可靠地结合于所述面板11B。优选地,所述弹性悬边22B的所述外侧连接边225B的全部部分可以被容纳于所述面板11B的所述接合槽112B内,通过这样的方式,有利于降低所述高音扬声器的高度尺寸,进而有利于所述高音扬声器的小型化。
在本发明的所述高音扬声器的一些示例中,所述面板11B的所述接合槽112B可以是环形接合槽,而在本发明的所述高音扬声器的另一些示例中,所述面板11B的上表面的至少一部分通过下凹的方式形成至少一个所述接合槽112B,若所述面板11B的所述接合槽112B的数量超过两个时,相邻所述接合槽112B之间相互独立。另外,所述接合槽112B的形状和尺寸在本发明的所述高音扬声器中不受限制,其允许根据需要被选择。
更优选地,所述面板11B具有至少一接合穿孔113B,其中所述接合穿孔113B贯穿所述面板11B的上表面和下表面,并且在附图12至图14示出的所述高音扬声器的这个具体的示例中,所述接合穿孔113B连通所述接合槽112B,其中所述弹性悬边22B进一步包括至少一悬边接合部226B,其中所述悬边接合部226B自所述外侧连接边225B的外周边缘向下一体地延伸,并且所述悬边接合部226B被保持在所述面板11B的所述接合穿孔113B内,通过这样的方式,能够进一步增加所述弹性悬边22B和所述面板11B的结合强度。例如,在附图15示出的阶段,所述面板11B的所述接合穿孔113B连通所述成型空间93B,从而在附图16示出的阶段,被加入所述成型空间93B的所述成型材料100B会流入并填充至所述面板11B的所述接合穿孔113B,从而在所述成型材料100B固化后,所述弹性悬边22B的所述悬边接合部226B会被保持在所述面板11B的所述接合穿孔113B。
值得一提的是,所述面板11B的所述接合穿孔113B的形状和尺寸在本发明的所述高音扬声器中不受限制,例如,在本发明的所述高音扬声器的一些示例中,所述面板11B的所述接合穿孔113B是直筒式的穿孔。而在本发明的所述高音扬声器的另一些示例中,所述面板11B的所述接合穿孔113B是倒锥形的穿孔,即,所述接合穿孔113B的靠近所述面板11B的上表面的部分的内径尺寸小于所述接合穿孔113B的靠近所述面板11B的下表面的部分的内径尺寸。当然,在本发明的所述高音扬声器的另外一些示例中,所述面板11B的所述接合穿孔113B也可以是分段式的穿孔,例如所述面板11B的所述接合穿孔113B为二段式,其中所 述接合穿孔113B的上段靠近所述面板11B的上表面,所述接合穿孔113B的下段靠近所述面板11B的下表面,且所述接合穿孔113B的上段内径尺寸小鱼所述接合穿孔113B的下段内径尺寸。
更进一步地,所述面板11B具有一保持槽114B,其中所述面板11B的所述保持槽114B形成于所述面板11B的下表面,其中在向所述成型空间93B加入所述成型材料100B之后,所述成型材料100B会通过所述面板11B的所述接合穿孔113B进入所述面板11B的所述保持槽114B,而在所述面板11B的所述保持槽114B内形成一体地结合于所述悬边接合部226B的一悬边保持部227B,通过这样的方式,能够进一步防止所述弹性悬边22B的所述外侧连接边225B从所述面板11B上脱落。
因为在现有技术的高音扬声器中,悬边是通过胶水粘结在面板上的,因此,悬边只能够与面板的表面结合,这种结构很容易导致悬边从面板上脱落。而在本发明的所述高音扬声器中,在流体状的所述成型材料100B形成所述弹性悬边22B的过程中,所述弹性悬边22B的所述外侧连接边225B一体地结合于所述面板11B,从而通过在所述面板11B的上表面设有所述接合槽112B、设有贯穿所述面板11B的所述接合穿孔113B,和在所述面板11B的下表面设有所述保持槽114B的方式,能够在所述面板11B的所述接合槽112B、所述接合穿孔113B和所述保持槽114B内分别形成所述弹性悬边22B的所述外侧连接边225B、所述悬边接合部226B和所述悬边保持部227B,这样,所述弹性悬边22B能够被可靠地结合于所述面板11B,这是现有技术的高音扬声器意料不到的。
在附图21示出的所述高音扬声器的一个变形示例中,所述倒凹振膜21B也可以具有至少一振膜接合槽210B,其中所述弹性悬边22B的所述内侧连接边224B的一部分被容纳于所述倒凹振膜21B的所述振膜接合槽210B,通过这样的方式,所述弹性悬边22B的所述内侧连接边224B能够更可靠地结合于所述面板11B。而在附图22示出的所述高音扬声器的另一个变形示例中,所述弹性悬边22B的所述内侧连接边224B也可以同时结合于所述倒凹振膜21B的上表面和下表面,即,所述弹性悬边22B的所述内侧连接边224B能够将所述倒凹振膜21B的外周边缘的一部分包裹于其内,通过这样的方式,所述弹性悬边22B的所述内侧连接边224B能够更可靠地结合于所述面板11B,以防止在所述倒凹振膜21B被所述音圈30B驱动而来回振动的过程中,所述弹性悬边22B的所述内侧连接边224B从所述倒凹振膜21B上脱离,从而保证所述高音扬声器在被使用的过程中的可靠性。
进一步地,所述弹性悬边22B包括一体地延伸于所述悬边主体221B的多个弹肋222B,其中在附图12至图14示出的所述高音扬声器的这个具体的示例中,每个所述弹肋222B凸出地延伸于所述悬边主体221B,并且相邻两个所述弹肋222B之间的距离相等。而在附图23示出的所述高音扬声器的另一个具体的示例中,每个所述弹肋222B凹陷地延伸于所述悬边主体221B,并且相邻两个所述弹肋222B之间的距离下相等。在附图24示出的所述高音扬声器的另一个具体的示例中,在凸出地延伸于所述悬边主体221B的所述弹肋222B的两侧是凹陷地延伸于所述悬边主体221B的所述弹肋222B。附图25示出了所述高音扬声器的在一个具体的示例,所述弹肋222B包括一组内侧弹肋2221B和一组外侧弹肋2222B,其中每个所述内侧弹肋2221B分别自所述悬边主体221B靠近所述内侧连接边224B的一侧向所述悬边主体221B的靠近所述外侧连接边225B的一侧延伸,和每个所述外侧弹肋2222B分别自所述 悬边主体221B靠近所述外侧连接边225B的一侧向所述悬边主体221B靠近所述内侧连接边224B的一侧延伸,并且任意一个所述内侧弹肋2221B延伸至相邻所述外侧弹肋2222B之间,和任意一个所述外侧弹肋222B延伸至相邻所述内侧弹肋2221B之间。所述弹肋222B用于增强所述弹性悬边22B的刚性,从而在所述倒凹振膜21B被所述音圈30B驱动而来回振动以带动所述弹性悬边22B同步地产生形变的过程中,若所述倒凹振膜21B具有偏向一侧的倾斜趋势时,所述弹性悬边22B的相对于该侧的部分会拉动所述倒凹振膜21B,以避免所述倒凹振膜21B向该侧倾斜,通过这样的方式,所述弹性悬边22B能够始终限制所述倒凹振膜21B仅沿着所述高音扬声器的轴向方向来回振动。并且,因为所述弹肋222B能够以增强所述弹性悬边22B的刚性的方式限制所述倒凹振膜21B仅沿着所述高音扬声器的轴向方向来回振动,从而所述高音扬声器可以不需要现有技术的高音扬声器的定心支片,这样,不仅能够降低所述高音扬声器的制造成本,而且有利于所述高音扬声器的小型化,以使得所述高音扬声器的体积能够被进一步地缩小,进而扩大所述高音扬声器的适用范围,例如,本发明的所述高音扬声器适用于头戴式音效装置,例如耳机。更为重要的是,本发明的所述高音扬声器因为不需要定心支片,从而所述音圈30B与所述扬声器壳体10B的内壁之间的距离能够被有效地缩短,这样,能够有效地防止所述音圈30B在被所述磁回单元40B产生的电磁力驱动的过程中偏离所述高音扬声器的轴向方向,进而避免所述倒凹振膜21B偏离所述高音扬声器的轴向方向。优选地,所述弹性悬边22B的这些所述弹肋222B呈螺旋状地布置,以给所述倒凹振膜21B提供朝向所述高音扬声器的中心轴的向心力,从而使得所述倒凹振膜21B的振动方向被限制在所述高音扬声器的轴向方向。
值得一提的是,所述弹性悬边22B的所述弹肋222B的形状在本发明的所述高音扬声器中不受限制,例如,所述弹肋222B的横截面可以呈弓形、拱形、三角形、四边形、多边形、半圆形、半椭圆形、倒置的U形、倒置的V形等。
另外,还值得一提的是,所述弹性悬边22B的所述悬边主体221B的截面形状在本发明的所述高音扬声器中不受限制,例如所述弹性悬边22B的所述悬边主体221B的截面形状可以是但不限于褶皱形、拱形、或波形等形状。
进一步地,所述倒凹振膜21B进一步包括一凹振膜部213B和一体地形成于所述凹振膜部213B且环绕在所述凹振膜部213B的四周的一振膜结合部214B,即,所述振膜结合部214B自所述凹振膜部213B的四周向外侧延伸。优选地,所述振膜结合部214B的延伸方向垂直于所述高音扬声器的轴向方向。所述弹性悬边22B的所述内侧连接边224B一体地结合于所述倒凹振膜21B的所述振膜结合部214B。所述倒凹振膜21B的材料在本发明的所述高音扬声器中不受限制,优选地,形成所述倒凹振膜21B的材料可以是合金材料或者金属材料,例如铝。也就是说,所述倒凹振膜21B可以是一个合金振膜或者金属振膜,通过这样的方式,能够保证所述倒凹振膜21B的强度,以在所述倒凹振膜21B被所述音圈30B驱动时,在所述倒凹振膜21B在各个位置的振动幅度具有一致性,以增强所述高音扬声器的高音音效。
值得一提的是,所述倒凹振膜21B的成型方式在本发明的所述高音扬声器中不受限制,例如在所述高音扬声器的一些具体的示例中,所述倒凹振膜21B可以是冲压方式形成的,即,首先提供一倒凹振膜模板,例如所述倒凹振膜模板可以是金属模板或者合金模板,然后通过冲压工艺使所述倒凹振膜模板的中部向下凹陷,以使所述倒凹振膜模板的中部形成所述倒凹 振膜21B的所述凹振膜部213B,和使所述倒凹振膜模板的外周形成所述倒凹振膜21B的所述振膜结合部214B,即,所述倒凹振膜21B的所述振膜结合部214B和所述凹振膜部213B是一体式结构。而在所述高音扬声器的另外一些具体的示例中,所述倒凹振膜21B可以是一注塑件,即,将流体状的金属材料或者合金材料加入到一倒凹振膜成型模具中,当流体状的金属材料或者合金材料在所述倒凹振膜成型模具中固化且在对所述倒凹振膜成型模具执行拔模工艺后形成所述倒凹振膜21B。
所述高音扬声器的所述倒凹振膜21B的尺寸被提供,以使带有所述倒凹振膜21B的所述高音扬声器也能够发出2560Hz以上的高频的高音,甚至带有所述倒凹振膜21B的所述高音扬声器能够发出40kHz以上的超高频的高音。具体地说,所述倒凹振膜21B的弧形高度参数为H和弧形弧度参数为R,其中所述倒凹振膜21B的弧形高度参数H的取值范围为5mm-7mm(包括5mm和7mm),和弧形弧度参数R的取值范围为10mm-20mm(包括10mm和20mm)。经过电声测试系统的测试,本方的所述高音扬声器的所述倒凹振膜21B的所述弧形高度参数H的取值在5mm-7mm之间和弧形弧度参数R的取值在10mm-20mm之间时,能够得到附图11示出得波形,这表明所述高音扬声器能够发出2560kHz高频的高音,甚至所述高音扬声器能够发出40kHz高频的高音,这是现有技术的高音扬声器意料之外的,并且本发明的所述高音扬声器的这种结构克服了本领域技术人员的技术偏见。本领域技术人员认为,现有技术的高音扬声器只有将振膜的结构的中部设置为凸起的方式才能够使高音扬声器产生高音,并且现有技术的高音扬声器的高频普遍在20kHz-2560Hz左右,而在本发明的所述高音扬声器中,所述倒凹振膜21B呈内凹的形状,并且因为所述倒凹振膜21B的所述弧形高度参数H的取值被选择为5mm-7mm和所述弧形弧度参数R的取值被选择为10mm-20mm后,所述高音扬声器能够产生高品质的且高频在2560Hz以上的高频的高音,甚至能够产生高品质的且高频在40kHz以上的高频的高音,这克服了本领域技术人员的技术偏见,并且本发明的所述高音扬声器具有现有技术的高音扬声器意料之外的技术效果。
另外,本发明的所述高音扬声器的所述倒凹振膜21B呈内凹状,从而所述高音扬声器产生的高音能够被汇聚,相对于现有技术的采用具有凸起结构的振膜的的高音扬声器来说,本发明的所述高音扬声器产生的高音能够因为所述倒凹振膜21B的结构而被汇聚,从而使得所述高音扬声器的高音能够更为集中,以扩大所述高音扬声器的应用范围。例如,本发明的所述高音扬声器适于被应用于头戴式音效装置,例如耳机。
优选地,所述倒凹振膜21B的弧形高度参数H的取值范围为5.5mm-6.5mm(包括5.5mm和6.5mm),优选为6mm,所述倒凹振膜21B的弧形弧度参数R的取值范围为16mm-18mm(包括16mm和18mm),例如17mm。

值得一提的是,所述永磁体42B的类型在本发明的所述高音扬声器中不受限制,例如,所述永磁体42B可以是各种磁石,磁铁,或磁钢,如可以是金属系磁石、铁氧铁磁石、稀土类磁石等。在本发明的这个较佳实施例中,所述永磁体42B可以是钕铁硼磁石。
另外,所述磁回单元40B的所述磁保护套41B、所述永磁体42B和所述导磁体43B之间可以通过传统的胶水粘结工艺制作成一个整体,也可以通过注塑工艺一体地形成,本发明的所述高音扬声器在这方面也不受限制。
在附图20示出的阶段,所述磁回连接件48B和所述面板11B被结合在一起,然后,所述面板11B和所述后盖12B被结合在一起,从而藉由所述磁回连接件48B使所述磁回单元40B被保持在所述面板11B和所述后盖12B之间。具体地说,在附图12至14示出的所述高音扬声器的这个具体的示例中,所述磁回连接件48B进一步具有多个定位槽483B,所述面板11B具有多个定位舌111B,其中所述面板11B以所述面板11B的每个所述定位舌111B分别被插入和被保持在所述磁回连接件48B的每个所述定位槽483B的方式和所述磁回连接件48B相互结合。另外,所述定位舌111B和所述磁回连接件48B的用于形成所述定位槽483B的内壁可以通过胶水相互粘结。值得一提的是,所述面板11B和所述后盖12B的结合方式在本发明的所述高音扬声器中不受限制,例如所述面板11B和所述后盖12B的结合方式可以是锁扣组件、螺纹组件、热熔接合、超声波接合等。
进一步地,所述高音扬声器进一步包括一减震单元50B,其中所述减震单元50B被设置于所述扬声器壳体10B的所述后盖12B,在所述高音扬声器被安装于或者被设置于或者被摆放于一个物体的表面时,所述减震单元50B能够以被保持在所述后盖12B和该物体的表面的方式减少所述高音扬声器的振动,从而进一步提高所述高音扬声器的振动效果。优选地,所述减震单元50B由弹性材料制成。
在本发明的所述高音扬声器的这个具体的示例中,参考附图12至图14,所述高音扬声器进一步包括一带孔的保护罩60B,其中所述保护罩60B被设置于所述面板11B,并且所述保护罩60B被保持在所述振动单元20B的声波出射方向,以供保护所述振动单元20B,并增强所述高音扬声器的美观性。
