Description

扬声器模组
技术领域
本发明涉及电声领域,尤其是涉及一种声学性能好的扬声器模组。
背景技术
目前扬声器模组越来越重视失真性能,要求扬声器模组发声失真的全频段越低越好。现有技术的扬声器模组结构设计中都是优先保证扬声器模组后腔体积,后再确定前腔出声通道的大小,这样就可能导致出声通道靠近扬声器单体位置的内出声孔窄,从而使出声通道狭窄,出声不顺畅,高频失真升高,降低扬声器模组的声学性能。
因此,有必要提出一种改进,以克服现有技术扬声器模组的缺陷。
发明内容
本发明所要解决的技术问题是提供一种声学性能好的扬声器模组。
为了实现上述目的,本发明采用以下技术方案:
一种扬声器模组,包括壳体以及扬声器单体,所述壳体内设置有收容固定所述扬声器单体的腔体,所述扬声器单体将所述腔体分隔成为前声腔和后声腔,所述壳体上设置有出声孔,所述出声孔通过出声通道与所述前声腔连接,并且:所述扬声器单体为方形结构;所述出声通道包括靠近所述扬声器单体的内端以及与所述出声孔连通的外端;所述内端的宽度大于所述扬声器单体对应所述内端的轴边长度的五分之三。
作为一种优选的技术方案,所述出声孔设置于所述壳体侧壁。
作为一种优选的技术方案,所述壳体外侧对应所述出声孔位置设置有防尘网。
作为一种优选的技术方案,所述壳体对应所述后腔位置设置阻尼孔,所述阻尼孔位置设置有阻尼网布。
作为一种优选的技术方案,所述壳体对应所述扬声器单体安装位置设置有钢片。
作为一种优选的技术方案,所述扬声器单体设置有电连接件,所述扬声器模组还包括柔性线路板,所述单体电连接件与所述柔性线路板电结合。
作为一种优选的技术方案,所述壳体包括第一壳体及第二壳体,所述出声孔由所示第一壳体及所述第二壳体共同形成。
本发明的扬声器模组,壳体上设置有出声孔,前腔通过出声通道与出声孔连通,扬声器单体为方形结构,出声通道靠近扬声器单体的内端的宽度大于扬声器单体对应该内端的轴边的长度的五分之三。本发明扬声器模组,限定了出声通道与扬声器单体靠近的一端的宽度,该宽度与扬声器单体对应的轴边长度呈一定比例,可以保证出声顺畅,有效降低扬声器模组的高频失真。本发明扬声器模组结构设计,很好地解决了扬声器模组高频失真偏高的问题,有效改善了扬声器模组的音质,减小了发声气流冲击出声通道而产生的气流音,使扬声器模组发出的声音更加清晰,纯净,亲切。因此,本发明扬声器模组具有声学性能好的优点。
附图说明
图1为本发明扬声器模组具体实施方式仰视图;
图2为图1所示扬声器模组分解图;
图3为图1所示扬声器模组剖视图;
图4为图1所示扬声器模组内部结构示意图。
具体实施方式
下面结合附图,详细说明本发明内容:
如图2所示,本发明的扬声器模组,包括壳体,壳体包括第一壳体11和第二壳体12,第一壳体11和第二壳体12配合收容固定扬声器单体2,扬声器单体2将第一壳体11和第二壳体12形成的空腔分隔成为前声腔和后声腔(图中未标示),前声腔与扬声器单体2的出声孔连通。如图1所示,本发明扬声器模组壳体设置有出声孔7,出声孔7与前声腔连通,本发明扬声器模组,扬声器单体2发出的声音通过扬声器单体2的出声孔进入到前声腔,后经过模组的出声孔7传递到扬声器模组外部。
如图3及图4所示,本发明的扬声器模组,出声孔7通过出声通道6与前声腔连通,如图2及图4所示,扬声器单体2为方形结构,如图4所示,出声通道6包括靠近扬声器单体2的内端6a以及与出声孔连通的外端6b,扬声器单体2靠近内端6a的轴边的长度为L,内端6a的宽度为W,内端6a的宽度W大于轴边长度L的五分之三。内端6a的宽度大于扬声器单体2对应内端6a的轴边长度的五分之三,可以保证扬声器模组的出声顺畅,有效降低扬声器模组高频失真,改善扬声器模组声学性能,并且减小了发声气流冲击出声通道而产生的气流音,使扬声器模组发出的声音更加清晰,纯净,亲切。因此,本发明扬声器模组具有声学性能好的优点。
如图1所示,本实施例的扬声器模组,出声孔7设置于扬声器模组的壳体的侧壁,出声孔设置于侧壁,可以降低扬声器模组厚度,有利于扬声器模组的小型化设计。
如图3所示,模组壳体外侧对应出声孔位置设置有防尘网3,防尘网3可以避免外界杂物进入到扬声器模组内部,提高扬声器模组可靠性。
如图1所示,扬声器模组壳体上对应后腔位置设置有阻尼孔12a,阻尼孔12a内设置有阻尼网布5,阻尼孔12a可以保证扬声器模组前后声腔气压平衡,保证扬声器单体2的振膜正常振动,提高扬声器模组声学性能。
如图3所示,本实施例的扬声器模组,第一壳体11上对应扬声器单体2位置设置有钢片11a,钢片11a可以在保证壳体刚性的前提下降低壳体厚度,从而增大扬声器模组内部空间,增大扬声器单体2体积,提高扬声器单体2的出声效果,从而提高扬声器模组声学性能。
如图4所示,本实施例的扬声器模组还包括柔性线路板4,扬声器单体设置有电连接件2a,电连接件2a与柔性线路板4电结合,扬声器单体2通过柔性线路板4与外部电路电连接。
如图3所示,本实施例的扬声器模组,出声孔由第一壳体11和第二壳体12配合形成,简化壳体设计难度,提高壳体生产效率。
本发明扬声器模组,壳体上设置有出声孔,前腔通过出声通道与出声孔连通,扬声器单体为方形结构,出声通道靠近扬声器单体的内端的宽度大于扬声器单体对应该内端的轴边的长度的五分之三。本发明扬声器模组,限定了出声通道与扬声器单体靠近的一端的宽度,该宽度与扬声器单体对应的轴边长度呈一定比例,可以保证出声顺畅,有效降低扬声器模组的高频失真。本发明扬声器模组结构设计,很好地解决了扬声器模组高频失真偏高的问题,有效改善了扬声器模组的音质,减小了发声气流冲击出声通道而产生的气流音,使扬声器模组发出的声音更加清晰,纯净,亲切。
以上仅为本发明实施案例而已,并不用于限制本发明,但凡本领域普通技术人员根据本发明所揭示内容所作的等效修饰或变化,皆应纳入权利要求书中记载的保护范围内。
