Description

多股独立进出式音圈 技术领域
本发明涉及扬声器技术领域，尤其是指一种用于扬声器上的多股独立进出式音圈。
背景技术
随着市场需求的不断提高，便携式音响、手提电脑、平板电脑、手机等电子设备逐渐向薄型化方向发展，而且要求其声音质量越来越好，这就要求便携式音响、手提电脑、平板电脑、手机等电子设备的扬声器向着小型、薄型、高音质方向发展，对其的声学性能的要求也就随之提高。音圈是扬声器的重要组件之一。当交变音频电流通过音圈时，使音圈产生随音频变化的交变电流，切割磁力线产生机械振动，带动振膜振动发出声音。
相关技术的扬声器，其包括扬声器腔体、贴合于扬声器腔体内的振动膜和收容于扬声器腔体内并贴合于振动膜上的音圈。其中，音圈包括音圈架和缠绕于该音圈架上的连续的音圈线。现有的扬声器的音圈只有一根漆包线绕制而成，发声过程中不论高音中音还是低音均通过该根漆包线带动振动膜的震动产生，从而导致声音在音量和音色的转换中受到振动膜振动时惯性的影响及频率和电流的影响而导致声音产生一定程度的失真，限制了扬声器的音质提高，难以满足人们对更高品质的追求。另外，由于现有的音圈只有一根漆包线，同样的电压，其输出功率小，费电量大。
技术问题
本发明的目的是提供一种多股独立进出式音圈，其可克服现有扬声器在使用时失真，音质低的缺陷，使用时可使扬声器发出声音的音质得到明显提高。
问题的解决方案

一种多股独立进出音圈，其由ICE芯片控制作用，多股独立进出音圈为封闭线 圈，封闭线圈由以下步骤绕制而成：
a.将至少两根漆包线同步并排形成多股排线，漆包线相互独立，各自绝缘；
b.将多股排线绕制形成封闭线圈；每一根漆包线，都具有独立的电流进出端；
c.在ICE芯片的控制作用下，漆包线共同形成多进多出电接端，分别对应不同频率声音的振动驱动控制，不同声音频率由不同的漆包线绕制的线圈驱动。
上述的多股独立进出音圈，其还进一步包括有骨架音圈，多股排线绕制于音圈骨架上。
上述音圈骨架由补强纸层或/和铝箔层或/和高温胶带粘结而成。

上述的封闭线圈中的每个漆包线的线径相等。
上述多股排线中漆包线的数量为两根或以上。
上述的多股独立进出音圈，在绕制封闭线圈时，将至少两根漆包线并排形成多股排线，再用多股排线绕制成内外结构的线圈的第一层，依次绕制，形成内外结构的多股多层封闭线圈。。
发明的有益效果
有益效果
采用上述技术方案后，在使用时，本发明是由至少两根漆包线同步绕制成封闭线圈，且，不同的漆包线，各自独立，在ICE芯片的控制作用下，漆包线共同形成多进多出电接端，分别对应不同频率声音的振动驱动控制，不同声音频率由不同的漆包线绕组驱动，即每根漆包线用于承担扬声器声音中的不同部分，从而有效避免了不同声音所驱动的调频和电流在同一根漆包线上产生的相互影响干扰而影响音质的问题，即，漆包线独立的电流进出端的设置，减小了声音在音量和音色的转换中受到音膜振动时惯性的影响及频率和电流的影响，扬声器发出声音的音质得到明显提高，更为清晰。再者，本发明，同时几根漆包线， 与只有一根漆包线的音圈相比，耗电量降低。

实施该发明的最佳实施例
本发明的最佳实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
实施例一：
参考图1、2所示，本发明公开了一种多股独立进出式音圈，该多股独立进出音圈为封闭线圈，所述的封闭线圈由以下步骤绕制而成：
a.将三根漆包线1同步并排形成多股排线2，所述的漆包线1相互独立，各自绝缘；
b.将上述的三根漆包线形成的多股排线绕制形成圆形状的封闭线圈3；该封闭线圈的每一根漆包线，都具有独立的电流进出端；
c.在ICE芯片的控制作用下，三根漆包线共同形成三进三出的电接端，分别对应高音、中音和低音的振动驱动控制，三种声音的频率，由不同的漆包线绕制的线圈驱动。达到降低耗电量的作用及目的。
根据扬声器的安装环境和位置空间的不同，扬声器的形状也会有较大的区别，为提高电子产品内部的空间利用率，扬声器可以根据需要设计成圆形、椭圆型、矩形或跑道形等不同的形状，圆环状线圈、椭圆状线圈、矩形线圈或跑道形线圈正好配合不同形状的扬声器使用，结构简单，适用性广。
当然，扬声器也可以根据不同使用者的喜好设计成正方形、正六边形或正八边形，正方形线圈、正六边形线圈或正八边形线圈适用于上述形状的扬声器结构，扬声器供应种类更多样化，适用性更广。
在本实施例中，多股排线中的漆包线的线径相等，方便自动化设备的生产加工，音圈的绕制加工更加均匀美观，实用性较强。
本发明，在使用时，由于漆包线独立的电流进出端的设置，减小了声音在音量和音色的转换中受到振动膜振动时惯性的影响及频率和电流的影响，扬声器发出声音的音质得到明显提高，且扬声器瞬态特性好、灵敏度高，进步明显。
当然，根据使用环境的不同，人们对扬声器的音质需求也有不同，例如在户外吵杂的环境下使用的扬声器对音质的要求稍低，其扬声器中音圈中的声音频率可以仅仅区分为高音和低音两种频段，在此情况下，扬声器中音圈的数量设计为漆包线的数量为两根即可满足需求，具有结构相对简单，制造成本低，性价比高的优点；对于较大的耳机使用的扬声器，其对扬声器音质具有比较高的要求，将扬声器的声音从频率高到低可以分成高音、次高音、中音和低音四挡，此种环境下，采用漆包线的数量为四根的音圈能大大提高扬声器的音质效果，并能更大程度地减小不同调频和电流的声音信号的干扰，技术效果更突出，实用性更强。
实施例二：
参考图3、4所示，与实施例一相比，其不同之处在于：
其还进一步包括有音圈骨架4，封闭线圈3多股排线绕制于音圈骨架4上，即封闭线圈3的内径与音圈骨架4的外径相当。
在本实施例中，音圈骨架4由补强纸层或铝箔层或高温胶带粘结而成。也可以由补强纸层、铝箔层、高温胶带中的一个或两个或三个依次粘结而成。
优选地，补强纸层为由牛皮纸制成的纸管，铝箔层为由铝箔片制成的铝管。
在使用时，该音圈骨架4在保证音圈强度的前提下，还具有厚度薄、体积小、质量轻的优点，可明显提高扬声器各个频段的灵敏度，实用性较强。
实施例三：
参考图5、6所示，与实施例二相比，其不同之处在于：
在绕制所述的封闭线圈时，将至少两根漆包线并排形成多股排线2，在本实施例中，其是用三根漆包线并排开成多股排线，再用多股排线绕制成内外结构的线圈的第一层，依次绕制，形成内外结构的多股多层封闭线圈5。
本实施例的优点为，该音圈在工作时，能产生更大的动能，输出功率更高。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求的保护范围为准。
