Description

一种发声装置组件及模组 技术领域
本实用新型涉及电声转换技术领域，更具体地，本实用新型涉及一种发声装置组件及模组。
背景技术
发声装置一般包括磁路组件和振动组件。磁路系统包括磁轭、设置在磁轭中间位置的中心磁铁和边磁铁。边磁铁围绕中心磁铁设置并且与中心磁铁间隔设置从而形成磁间隙。为修正磁力线，在中心磁铁、边磁铁上一般设有华司。
振动组件包括结合在一起的振膜和音圈，音圈伸入磁间隙内。音圈通电时，磁路组件驱动振动组件振动。当振动组件振动时，会带动气流冲击中心磁铁上的华司，无法被及时疏导、交换，导致发声装置内部通气不畅。
而且，目前发声装置的后声孔一般设置在发声装置的外侧外壳处，位置较远。例如，当发声装置为矩形时，其后声孔通常设置在发声装置的拐角位置。磁间隙内的气流也不能及时排出。中心磁铁与振膜之间的气流更加不能及时被疏导、排出。导致发声装置内部通气不畅。
这对产品振幅均较大影响。尤其是，当发声装置振幅较大时，偏振对产品听音及测试良率影响较大。
因此，有必要对现有发声装置进行改进。

根据本公开的一个实施例，中心华司为中心镂空的环形。在中心华司与中心磁铁结合后，第一凹槽与中心磁铁围成第一通道。由于第一凹槽从中心华司的内环贯通延伸至外环，使第一通道的一端与中心华司的中心镂空导通、另一端与磁间隙导通。气流能够通过中心华司中心镂空、第一通 道进行交互，增加气流的交换率。均衡、疏通气流，减小因通气不畅引起的偏振。加大产品内阻，减小振幅，提高测试良率。
