Description

适用于小功率骨传导耳机的振子 技术领域
本发明涉及一种适用于小功率骨传导耳机的振子，属于骨传导耳机技术领域。
背景技术
声音传播有两种方式，一种是空气传导，简称气导，就是利用空气振动的原理，声音传到耳膜，再通过耳膜传到内部耳神经。目前市场上传统的耳塞式耳机都是利用空气振动的原理做成的产品，将耳机贴在耳朵孔或塞在耳朵孔内，耳机通过振动空气，空气再振动人的耳膜，而将声音传到人脑。这种耳塞式耳机，由于在使用时需要将耳机贴在耳朵孔或塞在耳朵孔内，当人们在过马路时就听不到汽车的鸣笛声，那是相当危险的；其次，传统耳机放进人的耳朵里，耳朵内空气阻塞，分泌的汗水挥发不出去，时间长了，会滋生细菌，造成耳膜病变。另外，传统耳机会有电磁波，对人的脑神经与听力神经造成伤害，如果长期大音量地使用这种耳机，对人的耳膜有影响，会引起人的耳鸣，严重地会造成听力下降。现有出现了一种骨传导耳机，将电信号变为震动信号，通过与人体的听骨接触，使人听到声音，声音不需要经过空气传播，耳机也不必贴在耳朵孔或塞在耳朵孔内。但是现有高低频音效可调的骨传导震子结构存在以下缺陷：1、安装在耳机主体内漏音严重；2、内部结构导致杂音现象发生；3、声音立体声效果差；4、外部震动感太大，影响佩戴的舒适性；5、音频效果差，当大功率振子工作时，振动片容易接触到外壳。
发明内容
针对现有技术存在的不足，本发明的目的就在于提供了一种适用于小功率骨传导耳机的率振子。
为了实现上述目的，本发明采用的技术方案是这样的：一种适用于小功率骨传导耳机的振子，包括外壳以及振动片，所述外壳呈筒状，其内底部设置有径向向内的凸台；所述振动片包括振动片本体、开设在所述振动片本体上的槽口组，所述槽口组至少包括第一槽口、第二槽口，所述第一槽口与第二槽口均呈M形，且第一槽口的一端设置于第二槽口靠近第一槽口一端的外侧；所述振动片本体设置于凸台上，且振动片本体朝向所述外壳开口的一侧设置有支架；所述支架呈碗状并碗口朝向所述外壳开口的一侧，且支架的碗底设置有磁铁；所述 外壳的开口处设置有线路板与上盖，所述线路板靠近支架的一侧设置有线圈，该线圈与所述磁铁同心设置并至少部分包覆磁铁；所述上盖设置于线路板朝向外壳开口的一侧外，且上盖的上端面与外壳的上端面平齐。
作为一种优选方案，所述振动片与外壳形成的空间内设置有泡棉。
作为一种优选方案，所述振动片与线路板之间设置有支撑架，所述支撑架呈环形。
作为一种优选方案，所述振动片呈圆形。
作为一种优选方案，所述振动片的厚度为0.15mm。
作为一种优选方案，所述支架的碗底居中设置有收容所述磁铁的凹槽。
作为一种优选方案，所述线圈与所述线路板电连接。
与现有技术相比，本发明所达到的有益效果：本发明通过电信号的强弱变化实现磁铁在磁场力的作用下发生振动，从而带动振动片振动，压缩空气产生声音，使人的听骨听到声音，不会对人的耳膜造成任何影响，而且结构简单，没有杂音，在振动片与外壳之间设置有泡棉，缓冲大功率振子工作时振动片容易接触到外壳的问题，能减少外部振动，实现降噪，佩戴舒适，同时，并在振动片上开设有M型槽口，提高了低频效果，适合各种使用者，适用范围广。

具体实施方式
下面结合具体实施例对本发明作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
实施例：
如图1、图2、图3所示，一种适用于小功率骨传导耳机的振子，包括外壳1以及振动片2，所述外壳1呈筒状，其内底部设置有径向向内的凸台11；所述振动片2包括振动片本体20、开设在所述振动片本体20上的槽口组，所述槽口组包括第一槽口21、第二槽口22、第三槽口23、第四槽口24，所述第一槽口21与、第二槽口22、第三槽口23、第四槽口24均呈M形，且第一槽口21的一端设置于第二槽口22靠近第一槽口21一端的外侧，第二槽口22的一端设置于第三槽口23靠近第二槽口22一端的外侧，第三槽口23的一端设置于第四 槽口24靠近第三槽口23一端的外侧，第四槽口24的一端设置于第一槽口21靠近第四槽口24一端的外侧；所述振动片本体20设置于凸台11上，所述振动片2与外壳1形成的空间内设置有泡棉3，且振动片本体20朝向所述外壳1开口的一侧设置有支架4；所述支架4呈碗状并碗口朝向所述外壳1开口的一侧，所述支架1的碗底居中设置有收容所述磁铁的凹槽41，且支架4的碗底设置有磁铁5；所述外壳1的开口处设置有线路板6与上盖7，所述线路板6靠近支架4的一侧设置有线圈8，该线圈8与所述磁铁5同心设置并至少部分包覆磁铁5；所述上盖7设置于线路板6朝向外壳1开口的一侧外，且上盖7的上端面与外壳1的上端面平齐；所述振动片2与线路板6之间设置有支撑架9，所述支撑架9呈环形；所述线圈8与所述线路板6电连接。振子结构内部安装稳固，没有杂音，同时磁铁5将振动传递给振动片2，振幅大，且振动片2上开设有M型槽口，提高了低频效果，适合各种使用者，适用范围广。
本发明优选振动片2的厚度为0.15mm，振动片2呈圆形但并不局限于圆形，也可以为椭圆形、方形等。振动片采用金属振动片2，并在振动片2与外壳1之间设置有泡棉3，当使用者音量较大时，振子工作振幅大，泡棉3可以起到缓冲的效果，减少外部震动感，提高佩戴的舒适性。
具体实施时，当线圈8通电时，随着电信号的强弱变化，磁铁5在磁场力的作用下发生振动，使得振动片2振动发出音频，杂音少，声音立体声效果好。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变形，这些改进和变形也应视为本发明的保护范围。
