根据本发明的另一个方面，提供了一种电子设备。该设备包括本发明提供的麦克风防风噪装置。
本发明的一个技术效果是，该麦克风防风噪装置，在使用时被连接到麦克风本体的麦克声孔上。声音经由第一声孔和/或第二声孔、第一腔体、连通通道、第二腔体到达麦克声孔，以实现声音的拾取。第一声孔和第二声孔通过第一腔体连通。通过这种方式，由其中一个声孔进入的风能从另一个声孔流出，这样能有效地将风进行泄压，防止风大量地进入麦克声孔以形成风噪。
此外，由第一声孔和/或第二声孔进入的风在第一腔体内得到缓冲，有效地减小了风的压力和流速，从而降低了风噪。
此外，第一挡流部和第二挡流部对由各自相对的声孔进入的风形成阻挡，吸收了风的能量，并且改变了风的方向，延长了风流经的路径，防止风直接进入连通通道中，从而降低了风噪。
此外，连通通道的入口位于第一挡流部和第二挡流部之间，这样可以使来自两个声孔的风的压力和流速都能得到消减。
此外，连通通道延长了风流经的路径，有效地降低了风的压力和流速，从而降低了风噪。
此外，第二腔体能使来自连通通道的风进一步得到缓冲，从而再次降低风的压力和流速，进一步降低了风噪。
此外，风流经第一声孔和/或第二声孔、第一腔体、连通通道、第二腔体。在该过程中，风的方向多次改变，风的能量多次被消减，从而有效地降低了风的流速和压力，进一步降低了风噪。

在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例 性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
根据本发明的实施例，提供了一种麦克风防风噪装置10。该装置包括第一声孔11、第二声孔12、第一腔体13、第二腔体14和连通通道。第一声孔11通过第一腔体13与第二声孔12连通。第一声孔11和第二声孔12用于拾取外部的声音，并且都能起到泄压的作用。
在第一腔体13内设置有与第一声孔11相对的第一挡流部和与第二声孔12相对的第二挡流部。例如，第一挡流部全部覆盖第一声孔11，第二挡流部全部覆盖第二声孔12。第一挡流部和第二挡流部用于阻挡由外部空间进入第一腔体13内的风，并且改变气流方向，降低流速。
连通通道用于连通第一腔体13和第二腔体14。第二腔体14与麦克声孔17连通，以将拾取的声音传递到麦克风本体26中。麦克声孔17即麦克风的声音入孔。连通通道的入口19位于第一挡流部和第二挡流部之间。
本发明实施例的麦克风防风噪装置10，在使用时被连接到麦克风本体26的麦克声孔17上。声音经由第一声孔11和/或第二声孔12、第一腔体13、连通通道、第二腔体14到达麦克声孔17，以实现声音的拾取。第一声孔11和第二声孔12通过第一腔体13连通。通过这种方式，由其中一个声孔进入的风能从另一个声孔流出，这样能有效地将风进行泄压，防止风大量地进入麦克声孔17以形成风噪。
此外，由第一声孔11和/或第二声孔12进入的风在第一腔体13内得到缓冲，有效地减小了风的压力和流速，从而降低了风噪。
此外，第一挡流部和第二挡流部对由各自相对的声孔进入的风形成阻挡，吸收了风的能量，并且改变了风的方向，延长了风流经的路径，防止风直接进入连通通道中，从而降低了风噪。
此外，连通通道的入口19位于第一挡流部和第二挡流部之间，这样可以使来自两个声孔的风的压力和流速都能得到消减。
此外，连通通道延长了风流经的路径，有效地降低了风的压力和流速，从而降低了风噪。
此外，第二腔体14能使来自连通通道的风进一步得到缓冲，从而再次降低风的压力和流速，进一步降低了风噪。
此外，风流经第一声孔11和/或第二声孔12、第一腔体13、连通通道、第二腔体14。在该过程中，风的方向多次改变，风的能量多次被消减，从而有效地降低了风的流速和压力，进一步降低了风噪。
图1是根据本发明实施例的麦克风防风噪装置10的结构示意图。图2是根据本发明实施例的麦克风防风噪装置10的剖视图。图3是根据本发明实施例的麦克风防风噪装置10的另一个角度的剖视图。
如图1所示，麦克风防风噪装置10具有长方体的结构。第一声孔11、第二声孔12、第一腔体13、连通通道和第二腔体14均被开设在长方体内。第一挡流部和第二挡流部均为挡板，例如第一挡板15和第二挡板16。
需要指说明的是，这里所指的长方体可以是近似为长方体的结构，其具有六个面。例如，边可以做成倒角。例如，在局部可以设置缺口或者凸起。只要大体上为长方体即可。
本领域技术人员可以根据实际需要设置第一声孔11、第二声孔12、第一腔体13、连通通道和第二腔体14的形状和尺寸以及两个挡板的形状和尺寸。
在一个例子中，连通通道的出口21与麦克声孔17错开设置。如图3所示，麦克声孔17与出口21错开，而不是直接相对。通过这种方式，避免了经过出口21的风直接冲击麦克声孔17，从而进一步降低了风噪。
在一个例子中，第一声孔11和第二声孔12相对设置。如图1所示，第一声孔11和第二声孔12的横截面为矩形。两个声孔被分别设置在长方体的两个相对的侧壁25上。这样，风从其中一个声孔到达另一个声孔较为顺畅。此外，这种结构便于加工制造。
例如，第一声孔11和第二声孔12的横截面可以是但不局限于圆形、椭圆形、正多边形或者不规则形状。
在一个例子中，第一声孔11和第二声孔12中的至少一个的延伸方向 与麦克声孔17的延伸方向垂直。如图2所示，两个声孔的延伸方向均与麦克声孔17的延伸方向垂直。例如，也可以是两个声孔中任意一个的延伸方向垂直于麦克声孔17的延伸方向。通过这种方式，避免了第一声孔11和/或第二声孔12直接与麦克声孔17相对，以使风不会直接吹到麦克声孔17上。
在一个例子中，连通通道包括垂直于第一声孔11和第二声孔12的连线的第一通道18。还包括垂直于第一通道18的第二通道20。第一通道18与第二通道20连通，第一通道18与第一腔体13连通，第二通道20与第二腔体14连通。例如，如图3所示，第一通道18和第二通道20连接在一起，以形成L形的连通通道，第一通道18垂直于第一声孔11和第二声孔12的连线。这样，风在进入麦克声孔17之前至少改变两次次方向。风在改变方向时会降低流速，从而降低了风噪。
在一个例子中，第一声孔11和第二声孔12被设置在长方体的侧壁25上，长方体的底壁23用于与麦克风本体26连接，由底壁23向内凹陷分别形成第一腔体13和第二腔体14。如图2和3所示，第一腔体13和第二腔体14均为一端敞开的结构。例如，第二腔体14的敞开端的面积大于麦克声孔17的截面积。
通过这种方式，在装置安装时，只需要将第二腔体14覆盖麦克声孔17，并且连通通道的出口21与麦克声孔17错开即可，从而降低了第二腔体14与麦克声孔17的安装精度，并使麦克风防风噪装置10的安装位置更灵活。
此外，在麦克风防风噪装置10与麦克风本体26连接完成后。第一腔体13和第二腔体14的敞开端被麦克风本体26封闭。通过这种方式，无需另外设置封闭结构。这样能够降低麦克风防风噪装置10的厚度，顺应电子设备轻薄化、小型化的发展趋势。
此外，第一腔体13和第二腔体14的开设更方便，降低了加工制造难度。
在一个例子中，第一腔体13包括与底壁23相对的顶部24。由顶部24向底壁23延伸形成第一挡流部和第二挡流部。第一挡流部与底壁23所 在的表面之间具有间隙22，第二挡流部与底壁23所在的表面之间具有间隙22。
例如，如图2和3所示，第一挡板15和第二挡板16均由顶部24延伸出，并且两个挡板的高度被配置为使两个挡板未延伸到底壁23所在的表面。这样，在麦克风防风噪装置10与麦克风本体26连接后，第一声孔11和第二声孔12通过两个间隙22实现连通，而无需在两个挡板上另外设置通孔。优选的是，第一挡板15和第二挡板16均垂直于顶部24，这样能进一步降低加工制造难度。
进一步地，在一个例子中，连通通道的入口19位于顶部24，并且连通通道至少部分被设置在顶部24中。如图3所示，第一通道18的入口19开设在第一腔体13的顶部24，并且入口19的延伸方向平行于第一挡板15或第二挡板16的延伸方向。第一通道18被开设在顶部24中。
在该例子中，风由第一声孔11进入后先经过第一挡板15与麦克风本体26之间的间隙22，再改变方向向上到达入口19，然后又改变方向流经第一通道18。通过这种方式，使风在第一腔体13内走过了最长的路径，并且多次改变方向，从而有效地降低了流速和压力。这样能进一步降低风噪。
同理，使风由第二声孔12进入后在第一腔体13内走过了最长的路径，并且多次改变方向，从而有效地降低了流速和压力。这样能进一步降低风噪。
在一个例子中，第一声孔11与第二声孔12相对于入口19对称，第一挡流部与第二挡流部相对于入口19对称。如图2所示，两个挡板和两个声孔分别相对于入口19对称。通过这种方式，能使来自两个声孔的风的压力和速度的消减更均衡，保证了降低风噪的效果。并且在安装麦克风防风噪装置10时，用户不需要区分两个声孔中哪个用来拾音，哪个用来泄压。通过这种方式，使得安装更方便。
在一个例子中，麦克风防风噪装置10是一体成型的。例如，该装置采用塑料、硅胶或者橡胶材质。用户可以通过注塑的方式一体形成第一声孔11、第二声孔12、第一腔体13、连通通道、第二腔体14、第一挡板15 和第二挡板16等结构。通过这种方式，大大降低了加工制造难度，并且保证了装置具有足够的结构强度。
其中，硅胶和橡胶具有较大的弹性，能够更有效地吸收风的能量。
根据本发明的另一个实施例，提供了一种电子设备。该电子设备可以是但不局限于耳机、手机、对讲机、电话机和智能手表等。该电子设备包括本发明提供的麦克风防风噪装置10。
该电子设备具有通话效果好的特点。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
