Description

一种发声装置模组 技术领域
本实用新型属于声电换能技术领域，更具体地，本实用新型涉及一种发声装置模组。
背景技术
发声装置模组是现代电子设备的重要声学器件，用于完成电信号与声信号之间的转换，是一种能量转换器件；随着电子产品的逐渐发展，发声装置模组技术也逐渐改善，适应电子产品对性能、结构的需要。目前广泛应用于电子设备中，如应用在手机、对讲机、笔记本等移动电子终端内的扬声器。
在现有技术中，发声装置模组中的前腔与出声口连通，前腔以及出声通道通常做成光滑的内壁表面，来避免能量损耗。但随着市场消费、产品设计以及生产加工工艺的进步，电子设备向小型化，轻薄化发展，这也要求发声装置模组也越来越精细，以适应电子产品的需要。发声装置模组外形受到整机组配的限制，在以振动发声单元为平面时，前腔往往与出声口的出声通道在空间上存Z轴方向的高度差，那么声音在传播过程中，不可避免的会产生反射，但内壁表面都是光滑的时候，通过多次反射，反射的声波就会在腔体内形成杂音，造成失真，降低用户体验。
因此，有必要提供一种改进的发声装置模组。
实用新型内容
本实用新型的一个目的是提供一种发声装置模组。
根据本实用新型的一个方面，提供一种发声装置模组，包括模组壳体，模组壳体相互组配在一起形成容纳腔；所述容纳腔包括前腔；所述模组壳体上设置有出声口，所述出声口通过出声通道与所述前腔连通，其中，所 述出声通道由部分或者全部所述模组壳体围合而成；形成所述出声通道的所述模组壳体的内壁表面全部或部分具有凹凸不平的结构。
可选地，形成所述出声通道的所述模组壳体的内壁表面经过粗化处理，所述粗化处理是电火花处理、蚀刻处理或表面喷涂处理中的一种方式或多种方式相结合。
可选地，形成所述出声通道的所述模组壳体的内壁表面具有火花纹。
可选地，所述凹凸不平的结构与所述模组壳体一体注塑成型。
可选地，所述凹凸不平的结构为矩阵式的内凹或/和外凸结构。
可选地，所述模组壳体包括第一壳体和第二壳体，所述第一壳体与第二壳体扣合形成所述出声通道。
可选地，所述模组壳体包括若干壳体，所述出声口设置在其中一个壳体上，或者由所述若干壳体共同围合而成。
可选地，所述模组壳体包括第一壳体，所述出声口设置在所述第一壳体上。
可选地，还包括发声装置单体，所述发声装置单体设置在所述容纳腔内，将所述容纳腔分隔为所述前腔与后腔。
本实用新型的一个技术效果在于，能够使声波在传播反射过程中形成无规律的散射，相互抵消耗散，改善声音在出声通道内由于反射方向一致而产生杂音、失真等的不良。
通过以下参照附图对本实用新型的示例性实施例的详细描述，本实用新型的其它特征及其优点将会变得清楚。

具体实施方式
现在将参照附图来详细描述本实用新型的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本实用新型的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本实用新型及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术和设备可能不作详细讨论，但在适当情况下，所述技术和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
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。
本实用新型提供的发声装置模组，能够避免声音在出声通道内由于反射方向一致而产生杂音。此外，能够提升发声装置模组的音质，避免失真。
如图1所示的一种发声装置模组，包括模组壳体1。模组壳体1内具有前腔11和出声通道12。模组壳体上设置有出声口13。出声口13通过出声通道12与前腔11连通，使得前腔11内的声音能够通过出声口13传递至发声装置模组外。出声通道12的内壁表面14全部或部分具有凹凸不平的形状，使得声音由前腔11传递至出声通道12内时，声音的音波在出声通道12内的内壁表面14上形成无规律的慢射；相对于光滑的内壁表面14，无法形成方向相对一致的音波反射，相对一致的音波多次反射相互叠加增强后，音波就会在腔体内形成杂音，造成失真，凹凸不平的内壁表面14，无法形成方向相对一致的反射，也就能够避免杂音的形成，提升发声装置 模组的音质，避免失真。
可选地，出声通道12的内壁表面14可以经过后期粗化处理，通常是模组壳体在生产加工时的机械化处理，使得其内壁表面14凹凸不平。所述粗化处理可以是电火花处理、蚀刻处理或表面喷涂处理中的一种方式或多种方式相结合，在出声通道12的内壁表面14成型后，对其进行处理，使得其凹凸不平。例如，图2和图3中所示的，通过注塑等方式成型的光滑的内壁表面14，经过电火花粗化处理后，在内壁表面14上形成的那种凹凸不平的火花纹2。
可选地，所述凹凸不平的形状，也可以是通过预设模具，使得出声通道12的内壁表面14上凹凸不平的形状在模组壳体1注塑时一体成型，也就不需要后期的粗化处理，能够简化发声装置模组的加工工艺。例如，在模具中，出声通道12的内壁表面14所对应的位置，设置规则的、或者不规则的凹凸点、菱形块等一些具体的立体形状，也可以是一些无规则的形状，本申请对此并不限制，能够使得通过注塑成型的出声通道12的内壁表面14凹凸不平即可。
可选地，在其他的实施方式中，可以在内壁表面14上形成为矩阵式的内凹或/和外凸形状，便于设计使用，在多批次的发声装置模组中能够得到基本统一的音质，差异不会过大。在使用预设模具，通过一体注塑制造这种发声装置模组时，也便于模具的设计制造。
可选地，模组壳体1可以包括若干壳体，所述若干个壳体能够结合成模组壳体1的一部分或者全部。出声通道12由所述若干壳体围合而成，能够便于加工组装；也便于在对出声通道12的内壁表面14进行粗化处理时，能够将内壁表面14直接暴露在外界，直接进行粗化处理。例如，如图1-3中所示的，模组壳体1包括第一壳体15和第二壳体16，出声通道12的内壁表面14分为两个部分，分别位于第一壳体15和第二壳体16上，第一壳体15与第二壳体16扣合后，就能够形成一个完整的出声通道12；第一壳体15和第二壳体16也扣合组成了部分模组壳体1。本领域技术人员可以理解，在其他的实施方式中，内壁表面14也可以分别位于组成全部模组壳体1的所有壳体上，通过组装，能够形成完整的模组壳体1和出声通道12。 在一些其他的具体实施方式中，出身通道12也可以仅设置在构成模组壳体1的若干个壳体中的一个内，也是能够实现本实用新型的，本实用新型对此并不限制。
可选地，模组壳体1包括若干壳体。出声口13设置在其中一个壳体上，或者出声口13由所述若干壳体围合而成。例如，如图1-3中所示的，模组壳体1包括第一壳体15和第二壳体16，出声口13设置在第一壳体15上；在其他的实施方式中，也可以是出声口13分为两部分，分别设置在第一壳体15和第二壳体16上，经过第一壳体15和第二壳体16的扣合，形成出声口13，本实用新型对此并不限制。
可选地，如图1中所示的，所述发声装置模组还包括发声装置单体3，用于在工作时，产生声音。模组壳体1内具有容纳腔，用于容纳发声装置单体3。发声装置单体3设置在容纳腔内，将容纳腔分隔为前腔11与后腔17，前腔11用于传递声音，后腔17用于改善声音，调节音质。进一步地，发声装置单体3中包括振膜31，通过振膜31的振动来产生声音，前腔11位于振膜31的一侧，后腔17位于振膜31相对的另一侧。
虽然已经通过示例对本实用新型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，以上示例仅是为了进行说明，而不是为了限制本实用新型的范围。本领域的技术人员应该理解，可在不脱离本实用新型的范围和精神的情况下，对以上实施例进行修改。本实用新型的范围由所附权利要求来限定。
