骨传导是一种声音传导方式，即将声音转化为不同频率的机械振动，通过人的颅骨、骨迷路、内耳淋巴液传递、螺旋器、听神经、听觉中枢来传递声波。相对于通过振膜产生声波的经典声音传导方式，骨传导省去了许多声波传递的步骤，能在嘈杂的环境中实现清晰的声音还原，而且声波也不会因为在空气中扩散而影响到他人。

音圈20安装于上述的磁性组件10的磁间隙14内。音圈20的作用是切割磁力线，产生电动势，只要能够实现该功能，其形状、结构、材质均可不做限定。
一实施例中，音圈20呈环形状，直接安装于上述的环形磁间隙14内。
请继续参照图1，振动件30安装于靠近磁性组件10的一端处，振动件30连接于音圈20且与音圈20电导通，从而将整个扬声器电导通，音圈20振动时振动件30随之产生振动，从而将振动传递给传导件40。
一实施例中，振动件30的外端部设有焊盘，通过该焊盘连接外部电路，从而将整个扬声器的电路导通。当然，振动件30也可以通过其他的方式导通外部电路。例如通过电路板导通外部电路。
一实施例中，振动件30为振动片。振动片的厚度较小，更加方便于传递振动。
一实施例中，振动件30由硬质材料制成且内置电路元件，音圈20连接于该振动件30并电连接该电路元件。由于音圈20直接连接振动件30，振动件30由硬质材料制成，可以保证与音圈连接时的稳定性，保证振动件30与音圈20振动时的稳定性。而一般的软质的振动件，则需要依靠辅助部件来连接音圈20，或者与音圈20之间设置间隙。
例如，振动件30为内置电路元件的钢片、塑胶片或碳纤维片。
当然，振动件30也可以采用其他的弹性元件制成，例如由普通的金属片制成，只是稳定性效果不如硬质材料。
传导件40连接于振动件30，是用于振动传导声音的元件。当振动件30振动时，振动传递至传导件40上。该传导件40通常可以是压电陶瓷片、PC传导片，也可以是其他的传导元件。
一实施例中，传导件40连接于振动件30远离磁性组件10的一端。
支撑部件50的作用是支撑振动件30以及磁性组件10，提供支撑使振动件30与磁性组件10的安装结构更稳定。支撑部件50例如可以是由塑料、铁、低碳钢等材料制成。支撑部件50与振动件30及磁性组件10之间的连接可以采用胶合、连接件连接等方式。
支撑部件50可由金属、塑胶以及其他的硬质材料制成。
支撑部件50可以仅支撑于磁性组件10与振动件30之间，也可以包住磁性组件10的两侧，还可以仅包住磁性组件10的一侧。本实施例中，支撑部件50呈环形状，安装于磁性组件10与振动件30之间。
一实施例中，上述的骨传导扬声器100还包括电路板60，该电路板60安装于第三导磁件17远离磁性组件10的一面，振动件30通过导电件电连接于电路板60。采用电路板60可以更方便地与外部电路连接。一实施例中，支撑部件50的外部开设有第一线槽，第一导磁件15的外侧开设有第二线槽，第一磁性件11的外侧均开设有第三线槽，导电件依次由第一线槽、第二线槽及第三线槽引导至电路板60。设置线槽一方面可以方便将导电件引导至电路板60处，另一方面可以将导电件隐藏，不让导电件露出，这样包住整个扬声器的外壳的体积也可以减小，方便于制备成微型的扬声器。其中的导电件例如为导线、导电片等等。
上述的骨传导扬声器100，还可以包括外壳，外壳包覆上述的各个部件，使得整个扬声器防止漏磁。上述的外壳可设置扩音孔，扬声器产生的声音可以由扩音孔发出至人耳。
实施例二
请参照图2，本实施例所述的骨传导扬声器，其与实施例一所述的骨传导扬声器基本相同，不同之处在于，第三导磁件17与第二磁性件12一体设置，第二磁性件12为可与磁体吸引的金属，第三导磁件17与第二磁性件12形成一个T形铁，T形铁更便于安装。此时由于第三导磁件17与第二磁性件12均可以导磁，第二导磁件16去需要去掉。
实施例三
请参照图2，本实施例所述的骨传导扬声器，其与实施例一或实施例二所述的骨传导扬声器基本相同，不同之处在于，支撑部件50呈环形，位于磁性组件10与振动件30之间且包覆磁性组件10的一侧。
实施例四
请参照图3，本实施例所述的骨传导扬声器，其与实施例一或实施例二所述的骨传导扬声器基本相同，不同之处在于，支撑部件50呈环形，包覆于磁性组件10的两侧，此时可在支撑部件50开设线槽，导电件可由支撑部件50的线槽伸出以连接于电路板60。
实施例五
本实施例提供一种骨传导耳机，其包括实施例一至实施例三任一项所述的骨传导扬声器。该骨传导扬声器安装在骨传导耳机内后，使得骨传导耳机可以做的较小，而且音质较好。
实施例六
本实施例提供一种骨传导助听器，其包括实施例一至实施例三任一项所述的骨传导扬声器。该骨传导扬声器安装在骨传导助听器内后，使得骨传导助听器可以做的较小，而且音质较好。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
