Description

受话器 技术领域
本发明涉及电声领域，具体的涉及一种受话器。
背景技术
受话器是一种能够实现电声能转化的器件，广泛应用于手机、电话等电子终端装置中。传统的受话器结构，一般包括磁路系统、振动系统以及收容磁路系统和振动系统的外部壳体，为了实现受话器与终端电子装置的电性连接，通常由中壳一体注塑结合有弹片，弹片在受话器内部与音圈的引线电连接，而外部则需要通过弹簧结构进行导通，现有技术中，弹簧的一端往往焊接在中壳的弹片上，另一端则与终端电子装置连接，由此实现外部电流信号至受话器内部的传递。
然而，如上所述，由于弹簧与中壳的弹片焊接，致使产品在横向上需要在已有振动系统尺寸的基础上延伸出组装弹簧的空间，这样便增大了产品的长度尺寸，不能满足终端装置横向装配空间的限制要求而中壳位于受话器产品的中间层，受限于产品组装的要求，难以将弹簧引导到振动系统的竖向位置。因此，需要提供一种新的受话器电连接结构设计方式，使其能够在不影响产品组装和横向空间的前提下，将弹簧引导至振动系统的竖向位置。
发明内容
本发明所要解决的技术问题是：提供一种受话器，通过对其电连接结构位置的改进，在不影响产品与终端装置组装和横向空间的情况下，将用于连接外部电路的弹簧引至振动系统的上方。
为了实现上述目的，本发明采用以下技术方案：一种受话器，包括外围壳体以及收容在所述外围壳体中的磁路系统和振动系统；所述振动系统包括振膜和音圈；所述外围壳体包括相互配合的第一壳体和第二壳体；所述第一壳体和 所述第二壳体上设置有相互导通的电连接结构，其中，所述第一壳体的侧壁上设置有第一弹片；所述第一弹片的一端焊接有电连接外部电路的弹簧，另一端裸露于所述第一壳体侧壁的外侧；所述第二壳体的侧壁上设置有第二弹片；所述第二弹片的一端与所述音圈的引线电性连接；所述第二弹片的另一端裸露在所述第二壳体侧壁的外侧，并且与所述第一弹片裸露于外侧的部分焊接固定。
作为一种改进，所述振动系统收容于所述第二壳体的空腔中；所述弹簧结合于所述第一壳体上，位于所述振动系统的上方。
作为一种改进，所述第一弹片包括与所述弹簧焊接固定的第一连接端以及裸露于所述第一弹片侧壁外侧的第一裸露端；所述第二弹片包括与所述音圈的引线电性连接的第二连接端以及裸露于所述第二弹片侧壁外侧的第二裸露端。
作为一种改进，所述第一裸露端上设置有焊线；所述第一裸露端与所述第二裸露端通过所述焊线焊接导通。
作为一种改进，所述第一弹片的第一裸露端、所述第二弹片的第二裸露端水平延伸至所述受话器的第一壳体、第二壳体的侧壁的外侧。
作为一种改进，所述第一裸露端向所述第二壳体的方向弯折，紧贴于所述第一壳体的侧壁上；所述第二裸露端对应向所述第一壳体的方向弯折，与所述第一裸露端搭接。
作为一种改进，所述第一裸露端与所述第二裸露端通过激光焊接固定并导通。
作为一种改进，所述第二弹片上设置有焊盘；所述音圈的引线点焊固定于所述焊盘上。
作为一种改进，所述第一弹片、所述第二弹片设置于所述第一壳体、所述第二壳体的同一端侧壁上。
作为一种改进，还包括第三壳体以及助听音圈；所述第三壳体与所述第二壳体相配合，结合于所述第二壳体的下方；所述振膜的中心位置结合有补强部；所述振膜的下侧结合有支撑所述振膜的金属环；所述磁路系统包括盆架、固定于所述盆架内的磁铁和华司。
相较于现有技术而言，本发明的受话器，其第一壳体上增加弹片结构(第一弹片)，第一弹片一端与弹簧焊接，另一端外露于第一壳体的侧壁，位于第二壳体上的第二弹片一端与音圈的引线焊接，另一端外露于第二壳体的侧壁，而第一弹片与第二弹片裸露在外侧的部分则通过焊线焊接导通，这种电连接结构的设计使得弹簧从产品的横向位置转移到了振动系统的上方，可以实现在不减小振动系统尺寸(不降低产品性能)的前提下缩减产品的横向尺寸，能够满足产品与终端电子装置组配时的横向尺寸的限制要求。
附图说明
图1为本发明受话器结构的爆炸图；
图2为本发明实施例一受话器结构的立体图；
图3为本发明实施例二受话器结构的立体图；
其中的附图标记包括：1、第一壳体，2、第二壳体，3、第一弹片，31、第一连接端，32、第一裸露端，320、焊线，4、第二弹片，40、焊盘，41、第二连接端，42、第二裸露端，5、弹簧，6、音圈，61、音圈引线，7、振膜，8、第三壳体，9、补强部，10、金属环，11、盆架，12、磁铁，13、华司，14、助听音圈。
具体实施方式
下面结合附图，详细说明本发明内容：
实施例一：
参阅图1所示，本发明的受话器包括外围壳体，具体而言，外围壳体包括自上而下相互配合的第一壳体1、第二壳体2以及第三壳体8，三者共同形成收容磁路系统和振动系统的空腔。进一步的，磁路系统包括盆架11、粘结固定于盆架上的磁铁12和覆盖于磁铁12表面的华司13，振动系统包括振膜7以及与振膜7粘结的音圈6，振膜7通过可以支撑振膜7的金属环10与第二壳体2固定；另外，为了增强产品在高频处的性能，振膜7的中心位置还结合有补强部 9，补强部9一般为刚性的复合层结构。
如上所述，磁路系统中，盆架11的侧壁和磁铁12之间设置一定的距离，形成磁间隙，音圈6的下端置于该磁间隙中。音圈6同时包括音圈引线61，音圈引线61与受话器的电连接结构电性连接。
参阅图1所示，本发明的受话器在第一壳体1和第二壳体2上设置相互导通的电连接结构：第一壳体1的侧壁上设置有第一弹片3，具体实施时，第一弹片3与第一壳体1一体注塑成型，第一弹片3的一端焊接有与外部电路电连接的弹簧5，而另一端则裸露于第一壳体1侧壁的外侧；同样的，第二壳体2的侧壁上一体注塑有第二弹片4，第二弹片4上设置有焊盘40，第二弹片4的一端通过焊盘40与音圈引线61焊接固定(通常为点焊)，而另一端裸露于第二壳体2侧壁的外侧。具体而言，第一弹片3包括第一连接端31与第一裸露端32，其中，与弹簧5焊接的为第一连接端31，而裸露于第一壳体1侧壁外侧的部分为第一裸露端32，同样的，第二弹片4具体包括第二连接端41与第二裸露端42，其中，与音圈引线61点焊固定的为第二连接端41，裸露于第二壳体2侧壁外侧的部分为第二裸露端42。
如上所述，本发明的受话器，其电连接结构包括第一弹片3、第二弹片4以及连通外部电路的弹簧5，如果实现内外部电路的导通，必须将第一弹片3与第二弹片4进行电导通，而本实施方式中，第一弹片3与第二弹片4通过wirebonding工艺连接，即在第一弹片3的第一裸露端32上设置有焊线320，通过焊线320将第二弹片4的第二裸露端42与第一弹片3的第一裸露端32焊接导通，由此实现第一弹片3与第二弹片4的电连接，完成内外部电路的导通，这样外部电路的电流信号可以通过弹簧5依次传递至第一弹片3、第二弹片4，最终到达与第二弹片4点焊固定的音圈6，音圈6接收到电流信号后，在电磁场的作用下做往复切割磁力线的运动，带动振膜7振动，进而向外界辐射声波，由此完成电能到声能的转化。
实施例二：
本实施方式与实施例一基本相同，其不同之处在于：
参阅图3所示，本实施方式中，第一弹片3与第二弹片4导通的方式与实施例一中不同，具体而言，第一弹片3的第一裸露端32、第二弹片4的第二裸露端42分别水平延伸至第一壳体3、第二壳体4的侧壁的外侧。进一步的，第一裸露端32向第二壳体4的方向弯折，紧贴于第一壳体3的侧壁上，对应的，第二裸露端42向第一壳体3的方向弯折，可与第一裸露端32搭接，第一裸露端32与第二裸露端42通过激光焊接固定并且导通。
本技术方案中，由于振膜7固定于第二壳体2上，即振动系统收容于第二壳体2的空腔中，而弹簧5结合于第一壳体3上，也就是说，本技术方案中，弹簧5从现有的横向位置移动至振动系统的上方，即竖向位置，可以避免现有技术中因弹簧横向空间设置而导致的无法满足横向尺寸限制要求的现象，同时，该种结构设计并不减小振动系统的尺寸，因此不会影响产品整体的声学性能。
优选的，为了便于装配，第一弹片3、第二弹片4设置于第一壳体1、第二壳体4的同一端侧壁上。
优选的，本发明的受话器还包括有助听音圈14。
需要说明的是，上述实施方式仅仅示出了单磁路结构的受话器，实际上，本技术方案的实施并不限于该种磁路结构的产品，对于同时包括两块边磁铁或者四块边磁铁等其他磁路结构的受话器同样可以适用，具体不受此限。
以上仅为本发明实施案例而已，并不用于限制本发明，但凡本领域普通技术人员根据本发明所揭示内容所作的等效修饰或变化，皆应纳入权利要求书中记载的保护范围内。
