Description

一种扬声器 技术领域
本发明涉及电声换能器件技术领域，尤其涉及一种扬声器
 背景技术
扬声器广泛应用于手机、笔记本电脑、助听器等便携性电子设备。随着这些便捷性电子设备的快速发展，人们对其的功能性要求越来越强，应用于其上的扬声器件也相应快速的发展。
目前，相关结构的扬声器包括盆架，收容于盆架的振动系统和磁路系统。而通常盆架采用一体化结构，并由塑料注塑成型或者金属材料制作。采用塑料制作的盆架，厚度过薄，强度不够，在保证强度够的前提下，需要将盆架的厚度保证在一定的范围内，这样则使得盆架与音膜胶合的接触面过大，导致音膜的折环宽度过小而影响产品的音频性能。而采用金属材料制作的盆架，一体结构的盆架则使得重量过大，进而使得使用此种盆架的扬声器显得笨重。
 技术问题
相关技术中盆架一体化设置的结构因盆架与音膜胶合面过大使得音膜折环宽度相应减少小而降低音频性能以及产品笨重的技术问题。

进一步地，磁路系统还包括叠设于副磁钢远离磁轭一侧的辅助磁钢，本体部避让辅助磁钢且位于辅助磁钢与音圈之间。
进一步地，固定部包括与振动部边缘连接的第一连接部以及自第一连接部朝金属嵌件方向弯折延伸的第二连接部，金属嵌件包括抵靠并固定第一连接部的第一固定面以及与第二连接部贴合固定的第二固定面。
进一步地，金属嵌件为金属环。
进一步地，主体部包括与振膜相对的支撑部，支撑部靠近振膜的一侧朝振膜方向延伸形成有突出部，金属嵌件套设在突出部外周。
进一步地，延伸部与突出部远离金属嵌件的一侧固定，延伸部靠近振膜的一端与突出部齐平。
进一步地，支撑部朝振膜方向延伸形成有与突出部间隔设置的卡接部，卡接部与突出部之间形成收容安装金属嵌件的容置槽。
进一步地，金属嵌件、上夹板及主体部一体注塑成型。
进一步地，主体部还包括自支撑部远离振膜的一端朝远离金属嵌件的方向延伸的延伸柱，金属嵌件远离振膜的一侧延伸形成贴附于延伸柱外侧的金属延伸片。

参照图1-4 ，为本发明提供的一种扬声器的较佳实施例，该扬声器包括盆架1和收容于盆架1内的振动系统2和磁路系统3，振动系统2包括固定于盆架1的振膜21、驱动振膜21振动发声的音圈22以及设于音圈22相对两侧的弹性支撑件23，音圈22位于振膜21与弹性支撑件23之间，磁路系统3包括固定于盆架1的磁轭31、固定于磁轭31的主磁钢32、分别位于主磁钢32相对两侧且与主磁钢32间隔形成磁间隙的副磁钢33以及叠设于副磁钢33的上夹板34，上夹板34包括叠设于副磁钢33的本体部341、自本体部341的相对两端朝振膜21方向弯折延伸的延伸部342以及连接在延伸部342之间的连接部343，本体部341、延伸部342及连接部343围成环形；弹性支撑件23一端与音圈22固定、另一端与盆架1固定；连接部343与盆架1固定，弹性支撑件23位于连接部343与磁轭31之间；盆架1包括主体部11以及安装在主体部11靠近振膜21一侧的金属嵌件12，金属嵌件12位于主体部11与振膜21之间；振膜21包括振动部211以及自振动部211边缘延伸的固定部212，固定部212与金属嵌件12固定。
本发明提供的一种扬声器，由主体部11与金属嵌件12组成盆架1的基本构架，利用金属嵌件12的刚度性能来保证盆架1整体强度，进而可以增大振膜21折环的宽度来增加振膜21的振动空间使得产品的音频性能得以提升，还能提高产品的耐摔、耐挤压性能。在此基础上，将上夹板34通过主体部11与盆架1固定于一体，进一步地提升了盆架1强度，同时简化了装配工序，提高了生产效率。
在本实施例中，主体部11可以采用塑胶材料，如此即可以降低盆架1整体的重量，又可以提高金属嵌件12以及上夹板34与下述的支撑部111在盆架1上的连接稳固度。
进一步地，磁路系统3还包括叠设于副磁钢33远离磁轭31一侧的辅助磁钢35，本体部341避让辅助磁钢35且位于辅助磁钢35与音圈22之间。如此，可以提高扬声器的内部结构的紧凑性。
参见图5-6，具体地，固定部212包括与振动部211边缘连接的第一连接部2121以及自第一连接部2121朝金属嵌件12方向弯折延伸的第二连接部2122，金属嵌件12包括抵靠并固定第一连接部2121的第一固定面121以及与第二连接部2122贴合固定的第二固定面122。采用第一固定面121和第一连接部2121抵靠、第二固定面122和第二连接部2122贴合固定，以使金属嵌件12和振膜21形成连接贴合固定，进一步地，第二固定面122和第二连接部2122采用胶水胶合，如此可以增加金属嵌件12和振膜21之间的连接更加稳固。
参见图4，具体的，主体部11包括与振膜21相对的支撑部111，支撑部111靠近振膜21的一侧朝振膜21方向延伸形成有突出部112，金属嵌件12套设在突出部112外周。金属嵌件12套设在突出部112外周，使金属嵌件12能够稳定地固定于支撑部111上。支撑部111朝振膜21方向延伸形成有与突出部112间隔设置的卡接部113，该卡接部113与突出部112之间形成收容安装金属嵌件12的容置槽114，从而使金属嵌件12能够稳定地被夹置于卡接部113与突出部112之间，进一步提高金属嵌件12被固定的稳定性。
进一步地，主体部11还包括自支撑部111远离振膜21的一端朝远离金属嵌件12的方向延伸的延伸柱115，金属嵌件12远离振膜21的一侧延伸形成贴附于延伸柱115外侧的金属延伸片14。通过延伸柱115和金属延伸片14的配合，可以进一步提高主体部11和金属嵌件12的连接稳固度。
参见图6，进一步地，延伸部342与突出部112远离金属嵌件12的一侧固定，延伸部342靠近振膜21的一端与突出部112齐平，可以避免延伸部342凸出突出部112导致容易与振膜21抵接或者延伸部342低于突出部112导致上夹板34的强度过低。
参见图1，进一步地，弹性支撑件23包括固定在音圈22一端的柔性电路板231以及贴设在柔性电路板231远离音圈22一侧的下音膜232，柔性电路板231包括与音圈22连接的第一固定臂2311、固定在盆架1的第二固定臂2312以及连接在第一固定臂2311与第二固定臂2312之间的弹力臂2313，下音膜232包括正对弹力臂2313并朝远离弹力臂2313方向突出的弧形折环部2321。如此，由柔性电路板231和下音圈22共同对音圈22支撑，即达到支撑音圈22的目的，又可以将柔性电路板231和下音膜232组装巧妙地在扬声器内部，结构设计极其灵巧，产品的结构紧凑，使得产品的体积小巧。
在本实施例中，金属嵌件12、上夹板34及主体部11一体注塑成型，如此可以提高扬声器的整体性能，还能简化装配工序。
在本实施例中，金属嵌件12为金属环。采用环状的金属嵌件12，可以提高整个盆架1的结构稳定度。
以上的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
