Description

一种用于喇叭测试的辅助装置及喇叭测试装置 技术领域
本发明涉及智能终端的配件检测的技术领域，尤其涉及一种用于喇叭测试的辅助装置及喇叭测试装置。
背景技术
电声器件是智能终端配置不可或缺一部分。智能终端的电声器件的发声原理包括：动圈式，基本原理来自佛莱明左手定律，把一条有电流的导线和磁力线垂直的放进磁铁南北极间，道线就会受磁力线和电流两者的互相作用而移动，在把一片振膜依附在这根道线上，随着电流变化振膜就产生前后的运动。目前百分之九十以上的锥盆单体都是动圈式的设计；电磁式，在一个U型的磁铁的中间架设可移动斩铁片(电枢)，当电流流经线圈时电枢会受磁化和磁铁产生吸斥现象，并同时带动振膜运动。这种设计成本低廉但效果不佳，所以多用在电话筒和小型耳机上；电感式，和电磁式原理相近，不过电枢加倍，而磁铁上的两个音圈并不对称，当讯号电流通过时两个电枢为了不同的磁通量会互相推挤而运动。和电磁是不同处是电感是可以再生较低的频率，不过效率却非常的低；静电式，基本原理是库伦(Coulomb)定律，通常是以塑胶质的膜片加上铝等电感性材料真空汽化处理，两个膜片面对面摆放，当其中一片加上正电流高压时另一片就会感应出小电流，藉由彼此互相的吸引排斥作用推动空气就能发出声音。静电单体由于质量轻且振动分散小，所以很容易得到清澈透明的中高音，对低音动力有未逮，而且它的效率不高，使用直流电原又容易聚集灰尘。目前如Martin-Logan等厂商已成功的发展出静电和动圈混合式喇叭，解决了静电体低音不足的问题，在耳机上静电式的运用也很广泛；平面式。最早由日本SONY开发出来的设计，音圈设计仍是动圈式为主题，不过将锥盆振膜改成蜂巢结构的平面振膜，因为少人空洞效应，特性较佳，但效率也偏低；丝带式，没有传统的音圈设计，振膜是以非常薄的金属制成，电流直接流进道体使其振动发音。由于它的振膜就是音圈，所以质量非常轻，瞬态响应极佳，高频响应也很好。不过丝带式喇叭的效率和低阻抗对扩大机一直是很大的挑战，Apogee可为代表。另一种方式是有音圈的，但把音圈直接印刷在塑胶薄片上，这样可以解决部分低阻抗的问题，Magnepang此类设计的佼佼者。号角式，振膜推动位于号筒底部的空气而工作，因为声音传送时未 被扩散所以效率非常高，但由于号角的形状和长度都会影响音色，要重播低频也不太容易，现在大多用在巨型PA系统或高音单体上，美国Klipsch就是老字号的号角喇叭生产商；其他还有海耳博士在一九七三年发展出来的丝带式改良设计，称为海耳喇叭，理论上非常优秀，台湾使用者却很稀少。压电式是利用钛酸等压电材料，加上电压使其伸展或收缩而发音的设计，Pioneer曾以高聚合体改良压电式设计，用在他们的高音单体上。离子喇叭(Ion)是利用高压放电使空气成为带电的质止，施以交流电压后这些游离的带电分子就会因振动而发声，目前只能用在高频以上的单体。飞利浦也曾发展主动回授式喇叭(MFB)，在喇叭内装有主动式回授线路，可以大幅降低失真。
可见智能终端的电声器件的功能受到众多因素的影响。在智能终端设计和单体器件一定时，一个智能终端更换多单体都会出现不能音质和音效，这样差异来源于单体差异，单体差异有材质本身差异，还有就是供应商制造工艺和偷工减料导致的，所以单体管控测试就显的很重要。
目前大多公司听筒单体物料验证都是瑞森Trustsystem声信号测试系统和设备进行测试，Trustsystem声信号测试系统可实现对扬声器、麦克风、立体声耳机、USB数字麦克风、音频功率放大器或者蓝牙耳机的测试。但是当应用于喇叭测试时，由于Trustsystem声信号测试系统上夹子过大，在接触听筒单体(喇叭)的正负引脚时，常会出现短路和单体受力不均等现象，导致每个单体测试存在明显差异，严重影响单体测试数据准确性。
