在所有附图中相同的标号指示相似或相应的特征或功能。
具体实施方式
在以下对本发明具体实施例的表述中，出音孔为设置在喇叭盖上连通出音筒的孔；泄声孔为设置在喇叭盖上位于出音孔附近的孔，调音孔为设置在调音挡板用于调整泄声孔与外界导通大小的孔；通过调音孔与泄声孔的相互作用，使耳机前声腔与外界连通的孔(包括出音筒与泄声孔)的大小发生变化。为了实现耳机音质的多样化，本发明调整调音挡板与喇叭盖之间的相对位置，通过调音孔控制泄声孔的大小，进而实现耳机最终发出声音的孔径的大小变化，使耳机呈现不同的音乐风格。
为详细描述本发明的耳机结构，以下将结合附图对本发明的具体实施例进行详细描述。
图1示出了根据本发明实施例的耳机爆炸结构。
如图1所示，本发明实施例的耳机，包括耳机壳1、与耳机壳1适配连接的喇叭盖5、设置在喇叭盖5外侧的出音筒6、收容在耳机壳1和喇叭盖5所形成的腔体内的喇叭2以及设置在喇叭盖5内侧的调音挡板3；其中，在喇叭盖5上设置有出音孔、泄声孔和档位卡槽，出音筒6通过出音孔与调音挡板3连接；在调音挡板3上设置有档位凸起以及调音孔，档位凸起卡在档位卡槽 内；出音筒6在喇叭盖5上旋转，带动调音挡板3在喇叭盖5内旋转，使档位凸起卡在不同的档位卡槽内，最终通过调音孔调整泄声孔的出音面积。其中，喇叭2设置在调音挡板3远离喇叭盖5的一侧，喇叭2将耳机壳1和喇叭盖5形成的腔体分隔为前声腔和后声腔。当调音孔与泄声孔的位置相对应时，泄声孔和调音孔导通，此时耳机前声腔与外界导通的孔的面积即为泄声孔的面积与出音筒6的通孔面积(与出音筒6的筒径相关)之和；当调音孔与泄声孔的位置错开时，泄声孔被调音挡板3遮挡，此时耳机前声腔与外界导通的孔的面积仅为出音筒6的通孔面积。可知，通过旋转出音筒6使调音挡板3位于不同的位置，能够控制泄声孔的大小，从而调整耳机的中低频响应，使耳机呈现不同的音乐风格。
为防止调音挡板3与喇叭盖5之间结合不紧密而漏气，从而影响耳机的声学性能，在本发明的一个具体实施方式中，在调音挡板3与喇叭盖5之间设置相应的密封圈4，该密封圈4的设置，其一，能够提高调音挡板与喇叭盖之间的密封性能，确保耳机声学性能稳定；其二，在旋转出音筒6的过程中，减小调音挡板与喇叭盖之间的摩擦力，提高产品的使用寿命。
具体地，为详细描述本发明的密封圈、调音挡板、喇叭盖等结构，以下将结合附图分别对其进行详细描述。
图2-1和图2-2分别示出了根据本发明实施例的密封圈俯视结构和仰视结构。
如图2-1和图2-2所示，本发明实施例的密封圈4的结构与调音挡板的结构相适配，在密封圈4上设置有与泄声孔位置相对应的贯孔41；此外，在喇叭盖的内侧设置有与密封圈4结构相一致的密封圈收容槽，密封圈4放置在喇叭盖与调音挡板之间，并固定在密封圈收容槽内。通过密封圈4提高调音挡板与喇叭盖之间的密封性能，确保耳机声学性能稳定；并且，在旋转出音筒的过程中，能够减小调音挡板与喇叭盖之间的摩擦力，提高产品的使用寿命和用户体验。
图3-1和图3-2分别示出了根据本发明实施例的调音挡板的俯视结构和测试结构。
如图3-1和图3-2所述，本发明实施例的调音挡板3与出音筒固定连接，通过旋转出音筒能够使调音挡板3转动；其中，调音挡板3为环形结构，在 所述调音挡板3上设置有调音孔31和档位凸起32，通过旋转出音筒使档位凸起32卡在不同的档位卡槽内，实现出音孔与泄声孔不同程度的重合。
此外，为有效控制出音筒的旋转角度，还可以在调音挡板3上设置缺口33，通过缺口33与喇叭盖上的止挡块配合，控制出音筒的旋转角度，从而避免档位凸起32从档位卡槽或者滑道内滑出，对档位凸起造成磨损。
图4-1和图4-2分别示出了根据本发明实施例的喇叭盖仰视结构及沿A-A处的剖面结构。
如图4-1和图4-2所示，本发明实施例的喇叭盖5包括密封圈收容槽(未标出)、泄声孔51以及与调音挡板的档位凸起相适配的档位卡槽，其中，在档位卡槽之间设置有弧形的滑道，方便调音挡板的档位凸起在不同的档位卡槽之间的自由切换，可知，滑道的弧度与档位凸起的运动轨迹是相一致的。
在本实施例中以档位卡槽为两个的情况进行描述，具体分别为第一档位卡槽521和第二档位卡槽522，旋转出音筒使调音挡板的档位凸起卡在第一档位卡槽521内，使调音孔与泄声孔51的位置相对应，此时，泄声孔51完全导通，耳机前声腔与外界导通的孔最大；再次旋转出音筒，使调音挡板的档位凸起卡在第二档位卡槽522内，使调音孔与泄声孔51的位置交错，此时，泄声孔51被调音挡板遮挡，耳机前声腔与外界导通的孔的大小仅为出音筒的通孔的大小，即耳机前声腔与外界导通的孔最小。
需要说明的是，在本发明的耳机中，档位卡槽也可以设置为多个，在各相邻的档位卡槽之间均设置弧形的滑道，通过旋转出音筒使调音挡板处于不同的档位卡槽处，实现泄声孔51的导通面积在最大和最小值之间的调整，从而使耳机呈现多种不同的音乐风格。
此外，为与调音挡板上的缺口相配合，还可以在喇叭盖5上设置止挡块53，止挡块53设置在调音挡板的缺口内，在调音挡板的旋转过程中，通过调音挡板的缺口和止挡块53的碰触，能够控制出音筒的旋转角度。
图5-1和图5-2分别示出了根据本发明实施例的出音筒的侧视结构和A-A处的剖面结构。
如图5-1和图5-2所示，本发明实施例的出音筒6为阶梯圆柱状中空结构，实现耳机的前声腔与外界导通，其一端与外部的耳机套或者入耳胶套连接，另一端固定在喇叭盖的出音孔处，并与位于喇叭盖内侧的调音挡板固定连接， 通过在喇叭盖上旋转出音筒6，能够带动调音挡板的旋转，从而实现控制喇叭盖上的泄声孔的大小。
图6-1、图6-2和图6-3分别示出了根据本发明实施例的出音筒与喇叭盖组装结构一、沿A-A处的剖面结构以及仰视结构。
如图6-1至图6-3所示，在本发明实施例的出音筒6与喇叭盖5组装的一种状态中，调音挡板3的档位凸起旋转至第二档位卡槽内，此时调音孔与泄声孔51及密封圈4的贯孔相互交错，附图6-2中箭头所示方向表示声音走向，此时泄声孔51闭合，声音从出音筒6内发出。
图7示出了根据本发明实施例的出音筒与喇叭盖组装结构二。
如图7所示，在本发明实施例的出音筒6与喇叭盖5组装的另一种状态中，在图6-2的基础上继续旋转出音筒6，使调音挡板3的档位凸起经过第二档位卡槽以及位于第一档位卡槽和第二档位卡槽之间的弧形滑道滑动至第一档位卡槽内，此时调音孔与泄声孔51及密封圈4的贯孔相互导通，图7中箭头所示方向表示声音走向，此时泄声孔51导通，声音从出音筒6及泄声孔51同时发出。
如图1所示，在本发明的另一具体实施方式中，耳机还可以包括阻尼网7、入耳胶套8、耳机线以及固定耳机线的耳机线固定部9；其中，阻尼网7贴设在出音筒远离喇叭盖的一端，该阻尼网7的设置不仅能够阻挡外部的小颗粒污染物进入耳机内部，还能够调节耳机的声学性能；入耳胶套8套设在出音筒远离喇叭盖的一端，该入耳胶套8可以采用硅胶或高弹性聚酯等材料制作而成，在其插入耳道后能够与耳道紧密接触，以隔绝声音进入中耳和内耳内，达到隔音的目的。此外，耳机线固定部9与耳机壳固定连接，耳机线的一端穿过耳机线固定部9与喇叭连接，另一端设置有耳机插头，与外部便携式电子产品配合使用。
另外，本发明实施例的喇叭2包括单体外壳以及收容在单体外壳内的振动系统和磁路系统；磁路系统包括导磁轭、位于导磁轭中心位置的磁铁、位于磁铁远离导磁轭一侧的华司；振动系统包括振膜、固定在振膜一侧的音圈、位于振膜中心位置的补强部等。
通过上述实施方式可以看出，本发明提供的耳机，在喇叭盖内侧设置与出音筒相连接的调音挡板，通过旋转出音筒使调音挡板转动，从而通过调音 挡板及位于调音挡板上的调音孔对喇叭盖上的泄声孔进行不同程度的遮挡，从而调整耳机前声腔与外界的导通面积变换，达到改变耳机频率响应的目的，使耳机呈现多种不同的音乐风格，结构简单、操作方便、用户体验好。
如上参照附图以示例的方式描述了根据本发明提出的耳机。但是，本领域技术人员应当理解，对于上述本发明所提出的耳机，还可以在不脱离本发明内容的基础上做出各种改进。因此，本发明的保护范围应当由所附的权利要求书的内容确定。
