Description

发声器以及包括该发声器的电子设备 技术领域
本发明涉及电声转换技术领域。更具体地，涉及一种发声器以及包括该发声器的电子设备。
背景技术
发声器是一种能够将电能转化为声能的器件，属于最基本的发声单元，其广泛应用于手机等终端设备中。近年来，为了满足手机等电子产品的外观要求，电子产品的体积不断减小，外形趋于轻薄化，因此，安装在电子产品中的发声器的体积也趋于小型轻薄化。
如图1所示，目前的发声器包括外壳11和和收容于所述外壳11内的振动系统和磁路系统，所述振动系统包括振膜和音圈，音圈两侧各引出一条音圈引线，分别与外部电路的正、负极电连接形成回路，通过电磁感应原理使音圈振动并由此带动振膜振动发声，实现发声器的发声功能。其中，每条音圈引线通过设于发声器外壳11上的第一导电件12以及与第一导电件12电连接的第二导电件13与外部电路电连接。第一导电件12注塑于外壳11中，一端露出于外壳11内侧，与音圈引线电连接，另一端露出于外壳11外侧，与第二导电件13电连接，该第二导电件13同时与外部电路连接。第一导电件12和第二导电件13的电连接导通发声器内部电路和外部电路，从而实现发声器的发声功能。目前的发声器中第一导电件12与第二导电件13的电连接是通过焊接上下叠放的第一导电件12的焊盘和第二导电件13的焊盘实现的，第二导电件13的焊盘遮挡住下方的第一导电件12的焊盘，仅能从第二导电件13的焊盘上方对两个焊盘的接触面进行焊接。在焊接过程中，由于焊接时间和激光能量等因素的影响，可能会出现虚焊，虚焊现象将影响第一导电件12与第二导电件13连接的可靠性，进而影响发声器的音质和稳定性。但是目前第一导电件12与第二导电件13的焊接结构无法直观地检查第一导电件12和第二导电件13的焊接处是否存在虚焊，从而无法很好地保证发声器的品质。
因此，需要提供一种能够提高第一导电件与第二导电件电连接可靠性的发声器，提高发声器的音质和稳定性。
