Abstract

双磁体电声转换器至少有双磁体、磁罩、支架和极芯片。双磁体均呈圆柱形、同极性同轴线贴合并且置于同一磁罩内。由于同极性贴合，因此增加了磁动势，满足移动电话等电器对高声压、高灵敏度的技术难题；同时置于同一磁罩的结构，克服了已有技术漏磁的又一技术难题。

Description

双磁体电声转换器
所属技术领域
本实用新型在国际专利分类中，属于机电传感器小类，即H04R，特别涉及双磁体受话器或双磁体扬声器。
背景技术
已有的双磁体受话器或双磁体扬声器，其结构为圆柱形的内磁体同轴线反极性置于等高的环形外磁体上，无顶面帽状的磁罩其帽顶周面置于两磁体之间，分别形成内外磁路。这种双磁体电声转换器可以做成一体并且相背的受话器与扬声器，节省了安装空间，降低了成本。但它需要粘合，同时环形磁体的磁间隙中磁感应强度不能满足当前移动电话多和弦振铃所需的高声压；环形磁体置于磁罩之外，磁回路的漏磁也会影响周围电子设备。
实用新型内容
本实用新型的目的在于提供一种双磁体电声转换器，解决移动电话对高声压扬声器的要求。
公开新的方案如下：
一种双磁体电声转换器，至少含有磁体、极芯片、磁罩和支架，其特征在于呈倒置“凸”字形并且上下两端敞开的磁罩的台肩上，同轴线置有磁体甲；磁体甲的下面同轴线贴有极性同向的磁体乙；磁体甲的上面和磁体乙的下面，分别同心贴有各自的极芯片甲和极芯片乙；磁体甲、磁体乙分别与磁罩的内周面留有磁间隙，即形成各自的磁路；所说的磁罩同轴线固定于支架上。
按照上述方案制成的样品，其双磁体均为圆柱体并且同极性，避免了已有技术环形磁体成品率低，易发生极性错误的弊病，同时同极性结构较大提高了磁动势，保证了移动电话等电器对高声压和高灵敏度要求。所述双磁体均被磁罩屏蔽，因此克服了已有技术漏磁的技术难题。
附图说明
图为本实用新型一个实施例的示意图(音圈、振膜等省略)。其中：1、极芯片甲；2、磁体甲；3、磁罩；4、支架；5、接线片；6、磁体乙；7、极芯片乙。
具体实施方式
一种双磁体电声转换器，至少含有磁体2、6、极芯片1、7、磁罩3和支架4，呈倒置“凸”字形并且上下两端敞开的磁罩3的台肩上，同轴线置有磁体甲2；磁体甲2的下面同轴线贴有极性同向的磁体乙6；磁体甲2的上面和磁体乙6的下面，分别同心贴有各自的极芯片甲1和极芯片乙7；磁体甲2、磁体乙6分别与磁罩3的内周面留有磁间隙，即形成各自的磁路；所说的磁罩3同轴线固定于支架4上。通常磁体乙(6)与受话器的音圈、振膜相配，直径稍大的磁体甲2与扬声器的音圈、振膜相配。
磁体甲2和磁体乙6都采用钕铁硼材料。磁罩3用嵌入法固定于支架4的卡槽内。接线片5套卡在支架4一边的凸柱上。上述方案中，双磁体处于同一磁罩内，呈全内磁式结构，与已有技术中环形磁体露于磁罩外的结构完全不同。
