Description

音圈及设有该音圈的扬声器 技术领域
本实用新型涉及电声产品技术领域，特别涉及一种音圈及设有该音圈的扬声器。
背景技术
扬声器是便携式电子设备中一种重要的声学部件，用于将声波电信号转换成声音信号传出，是一种能量转换器件。扬声器通常包括振动系统和磁路系统，振动系统包括结合在一起的振膜和音圈，其中音圈是扬声器的驱动部件，当交变音频电流通过音圈时，音圈产生随音频电流而变化的磁场，这一变化的磁场与扬声器磁路系统的磁场发生相吸或相斥作用，使得音圈产生切割磁力线的机械振动，从而带动振膜振动而发出声音。现有的音圈通常由横截面形状为圆形的音圈线绕制而成，然而此种结构的音圈绕制成型后相邻音圈线之间均存在较大缝隙，使得音圈不能充分的利用磁场的能量，音圈的容积率低，从而导致扬声器的灵敏度差，音圈的散热能力差等。
针对上述横截面为圆形音圈线的问题，当前已有的解决方案为使用横截面为正方形的音圈线绕制音圈，横截面为正方形的音圈线的应用在一定程度上可以提高音圈的容积率，改善散热能力等，但由于横截面为正方形，绕制的音圈的高度和宽度均与正方形的边长成正比，这对于同时调整灵敏度和THD(Total Harmonic Distortion，谐波失真)而言存在一定的弊端，如使用增加音圈高度的方法来改善Bl(x)(作用在音圈上的磁场能量)的对称性就要求截面为正方形的音圈线必须具备更大的边长，但边长增大也会同时增大音圈宽度，从而增大磁间隙，减小了产品灵敏度。
针对上述截面为正方形音圈线的问题，技术人员提出了一种由横截面为长方形的音圈线绕制的音圈10a，如图2所示，此长方形音圈 线的长边尺寸与短边尺寸的比值A/B小于π，其中π＝3.1415926，音圈10a的宽度W由音圈线的短边构成，高度H由音圈线的长边构成。此种音圈线在应用上可通过调整长方形音圈线的长宽比使得音圈的高度和宽度在设计时可以得到很好的平衡和调整。但是此种音圈线在绕制音圈过程中音圈线容易发生旋转，如图1所示，从而导致绕音圈线排列异常，绕制出的音圈不规则；且音圈10a由四层音圈线12a绕制而成，音圈层数过多，且在绕线换层的位置音圈线就更容易发生旋转，绕制难度较大。
实用新型内容
针对以上缺陷，本实用新型所要解决的第一个技术问题是提供一种音圈，此音圈的音圈线在绕制时不会发生旋转，绕制难度低，生产效率高；同时相邻音圈线之间的缝隙小，音圈的容积率高，散热性能好，同时此音圈的高度和宽度在设计时可以得到很好的平衡和调整。
基于一个发明构思，本实用新型所要解决的第二个技术问题是提供一种扬声器，此扬声器的音圈绕制难度低，且灵敏度高，产品的THD等声学性能更容易调整。
为解决上述第一个技术问题，本实用新型的技术方案是：
一种音圈，由音圈线绕制而成，所述音圈线的横截面为长方形，所述长方形音圈线的长边尺寸与短边尺寸的比值为π～4π，且所述长方形音圈线的长边的延伸方向与所述音圈的宽度方向一致。
作为一种实施方式，所述长方形音圈线的长边尺寸与短边尺寸的比值是π。
其中，所述音圈的宽度是所述长方形音圈线的长边尺寸的2倍。
作为另一种实施方式，所述长方形音圈线的长边尺寸与短边尺寸的比值是4π。
其中，所述音圈的宽度与所述长方形音圈线的长边尺寸相等。
作为再一种实施方式，所述长方形音圈线的四个角部均设有圆弧 倒角。
其中，所述圆弧倒角的半径小于等于所述长方形音圈线的短边尺寸的1/2。
其中，所述音圈线为漆包线。
为解决上述第二个技术问题，本实用新型的技术方案是：
一种扬声器，包括振动系统和磁路系统，所述振动系统包括结合在一起的振膜和音圈，所述音圈为上述音圈。
采用了上述技术方案后，本实用新型的有益效果是：
由于本实用新型音圈由横截面为长方形的音圈线绕制而成,长方形音圈线的长边尺寸与短边尺寸的比值为π～4π，且长方形音圈线的长边的延伸方向与音圈的宽度方向一致。音圈线的长边尺寸与短边尺寸的比值为π～4π使得音圈线的长边与短边更容易区别，在绕制音圈的过程中不会发生线材旋转的现象，降低了绕制的难度；且由音圈线的长边构成音圈的宽度，音圈的音圈线层数可由现有的四层减少为两层或一层，进一步的降低了绕制的难度，提高了音圈绕制的效率，且相邻音圈线之间的粘接力更大。同时还具有相邻的音圈线之间缝隙小，音圈的容积率高，可充分的利用整个音圈所占用的磁场强度，可大大提高扬声器的灵敏度；且音圈的散热性能更好；可以通过调整长方形音圈线的长边与短边的比例灵活的调整音圈的高度和宽度，在灵活的改善扬声器THD的同时，不会影响音圈的宽度，同时也不会影响磁间隙的宽度，可大大的提高扬声器的声学性能的优点。
由于长方形音圈线的长边尺寸与短边尺寸的比值为π，此时横截面为长方形的音圈线可以获得直径与长方形音圈线短边尺寸相同的横截面为圆形的音圈线一致的横截面积，在相同的音圈阻值下，长方形音圈线具有更少的绕线层数，从而使得音圈的设计更容易，绕制难度更低。同时在音圈线的长边尺寸与短边尺寸的比值为π时，本实用新型中的音圈线与现有技术中长边尺寸与短边尺寸的比值为4/π，且 该音圈线的长边尺寸为本实用新型中音圈线的短边尺寸2倍的音圈线相比，在相同的音圈阻值下，二者将具有一样的音圈线长度、音圈高度和音圈重量，可以取得相同的声学性能，但是本实用新型在音圈绕制过程中音圈线不会发生旋转，绕制更容易，绕制效率更高。
由于长方形音圈线的长边尺寸与短边尺寸的比值为4π，此时横截面为长方形的音圈线可以获得直径为长方形音圈线短边尺寸2倍的横截面为圆形的音圈线一致的横截面积，在相同的音圈阻值下，长方形音圈线具有更少的绕线层数，从而使得音圈的设计更容易，绕制难度更低。
由于本实用新型扬声器的音圈为上述音圈，音圈的绕制难度低，绕制效率高，在保证音圈获得的较强磁场强度，提高灵敏度的同时，能够更容易的对音圈的高度和宽度进行调整，保证了产品的THD。
综上所述，本实用新型音圈及设有该音圈的扬声器解决了现有技术中音圈绕制难度大等技术问题，本实用新型音圈及设有该音圈的扬声器中音圈绕制难度低，绕制效率高，且扬声器灵敏度高，谐波失真小，声学性能好。

具体实施方式
下面结合附图和实施例，进一步阐述本实用新型。
实施例一：
如图3所示，一种音圈，音圈10b由音圈线12b绕制而成，音圈线12b的横截面为长方形。音圈线12b的长边的延伸方向与音圈10b的宽度方向一致，即音圈10b的宽度W′由音圈线12b的长边构成，音圈10b的高度H′由音圈线12b的短边构成。设长方形音圈线的长度(长边尺寸)为A′，宽度(短边尺寸)为B′，音圈线10b的长边尺寸与短边尺寸的比值为π～4π，即A′/B′＝π～4π，本实施方式优选为A′/B′＝π。当A′/B′＝π时，此时音圈线12b可以获得直径为B′的横截面为圆形的音圈线一致的横截面积，在相同的音圈阻值下，音圈10b具有更少的绕线层数，从而使得音圈的设计更容易，绕制难度更低。同时，与现有技术中A/B＝4/π、A＝2B′(如图2所示)的音圈线相比，在相同的音圈阻值下，二者将具有一样的音圈线长度、音圈高度和音圈重量，可取得相同的声学性能，但是本实用新型在音圈绕制过程中音圈线不会发生旋转，绕制更容易，绕制效率更高。
如图3所示，音圈10b的宽度W′是音圈线12b的长边尺寸A′的2倍，即音圈10b由两层音圈线12b绕制而成，绕线层数为现有技术中的一半，有效的降低了音圈绕制的难度，提高了音圈绕制的效率。
如图3所示，音圈线12b为漆包线，包括位于内侧用于导电的条形金属芯和包裹在金属芯外周的绝缘层。
实施例二：
如图4所示，本实施方式与实施例一基本相同，其不同之处在于：
音圈10c由音圈线12c绕制而成，音圈线12c的长边的延伸方向与音圈10c的宽度方向一致，即音圈10c的宽度W″由音圈线12c 的长边构成，音圈10c的高度H″由音圈线12c的短边构成,音圈线的长边尺寸与短边尺寸的比值为4π，即A″/B″＝4π。音圈10c的宽度W″与音圈线12c的长边尺寸A′相等，即音圈10c由一两层音圈线12c绕制而成。
本实施方式与实施例一相比，音圈线的长宽比进一步的加大，使得音圈的绕线层数由两层减少为一层，从而，本实施方式的音圈绕制更容易，绕制效率更高。
实施例三：
如图5所示，本实施方式与实施例一和实施例二均基本相同，其不同之处在于：
音圈10d由音圈线12d绕制而成，音圈线12d的四个角部均设有圆弧倒角，圆弧倒角的半径小于等于音圈线12d的短边尺寸的1/2。
圆弧倒角的设置可保证音圈线外侧胶层涂布均匀，相邻的音圈线之间粘接牢固，同时还能够增加音圈外形的美观度。
本实施方式仅给出了与实施例二基本相同的实施方式的附图，由于与实施例一基本相同的实施方式的附图技术人员根据图3及图5不需要付出创造性劳动即可绘出，故与实施例一基本相同的实施方式的附图在此省略。
实施例四：
一种扬声器，包括振动系统和磁路系统，振动系统包括结合在一起的振膜和音圈。音圈为实施例一、实施例二和实施例三中描述的音圈。
由于本实用新型扬声器采用了实施例一、实施例二和实施例三中描述的音圈，音圈的绕制难度低，绕制效率高，在保证音圈获得的较强磁场强度，提高灵敏度的同时，能够更容易的对音圈的高度和宽度进行调整，保证了产品的THD。
本实用新型不局限于上述具体的实施方式，本领域的普通技术人 员从上述构思出发，不经过创造性的劳动，所做出的种种变换，均落在本实用新型的保护范围之内。
