为了提高音响效果，具体实施过程中共振壳300采用具有良好振动发声性能的材料制成。
实施例二：
如图2所示，本实施例中共振壳与保护壳为分体式结构，共同组成头盔本体1，在本发明的具体实施例中所述共振壳300的数量可以为一个或多个，当所述共振壳300的数量为多个时，多个共振壳300在所述头盔本体1内呈对称结构分布，对应每个所述共振壳300设置有一个所述骨传导振子。通过设置多个共振壳3，能够在头盔本体1内部立体声效果。
优选的，在本实施例中所述共振壳300的数量为两个，分别设置在所述头盔本体1上位于头盔佩戴者耳部的位置。
实施例三：
本实施例与实施例一的基本结构相同，其主要区别在于，本实施例中所述头盔本体包括保护壳以及共振壳，所述共振壳为适宜人体头部佩戴的半球形结构，其设置在所述头盔本体的内侧，所述保护壳设置在所述共振壳外部，所述共振壳远离所述保护壳的一侧设置有缓冲层。
由于实现物理保护以及振动发声所需要的材料不同，在采用同一材料制作头盔本体时必然导致两者无法同时达到最高要求，通过单独设置保护壳以及共振壳，保护壳采用具有更好的抗物理冲击性能的材料制成，共振壳采用具有良好振动发声性能的材料制成，能够保证本实施例中的头盔，更好的实现本发明的目的。同时设置有缓冲层能够避免采用较硬材料制成的保护壳以及共振壳直接与佩戴者头部接触，影响使用舒适度。
实施例四：
如图3～6所示，于本实施例中，本发明所述的一种基于骨传导耳机200的可切换发声导向方式的骑行头盔，包括头盔本体1，以及位于所述头盔本体1上的骨传导耳机200，所述骨传导耳机200包括磁铁、线圈以及骨传导振子，所述骨传导振子可与所述头盔本体1接触，使所述头盔本体1发生振动形成音腔。
所述头盔本体1包括可与所述骨传导振子直接接触的共振壳，所述骨传导耳机200与所述头盔本体1可转动连接，使所述骨传导振子具有与所述共振壳接触的第一状态，以及与头盔佩戴者头部接触的第二状态。
本实施例中将骨传导振子设置为与头盔本体1可转动连接状态，在使用过程中，根据使用者的需要，可以将骨传导振子调节至第一状态位置，通过其与共振壳振动接触带动共振壳振动实现气导发声，或者将其调节至第二状态使所述骨传导振子与所述共振壳脱离，仅与佩戴者头部接触，实现骨导声。这种可选择的结构能够提高头盔使用的灵活性，根据不同的应用场合，给使用者更多的选择，提高用户体验。
具体的，本实施例所述的基于骨传导耳机200的可切换发声导向方式的骑行头盔，还包括第一转动臂400，所述第一转动臂400具有与所述骨传导耳机 200连接的第一转动臂400第一端，以及与所述头盔本体1连接的第一转动臂400第二端，所述骨传导耳机200通过第一转动臂400与所述头盔本体1铰接。
在所述头盔本体1上与所述头盔本体1一体注塑形成有旋转轴500，在所述第一转动臂400的所述第一转动臂400第二端设置有与所述旋转轴500相配合的轴孔，所述旋转轴500的端部设置有固定孔，所述第一转动臂400通过固定螺丝600与所述固定孔相配合轴向固定在旋转轴500上。
当然，骨传导耳机200与头盔本体1的连接方式并不局限于铰接形式，在其它实施例中，还可以采用伸缩式连接等其它连接方式。
实施例五：
如图7所示，本实施例所述的基于骨传导耳机200的可切换发声导向方式的骑行头盔，与实施例四所述的骑行头盔结构基本相同，其主要区别在于，本实施例中在所述头盔本体1上增加了用于在所述第一状态下收纳所述骨传导耳机200的容纳腔700，所述容纳腔700的至少一侧壁为所述共振壳300，在所述第一状态下所述骨传导耳机200位于所述容纳腔700中，并且所述骨传导耳机200的骨传导振子与所述共振壳接触。
在头盔佩戴者使用头盔进行骨导声的情况下骨传导耳机200位于容纳腔700外部，方便与人体接触，当采用气导声功能时，则可将骨传导耳机200收纳于所述容纳腔700中，使得头盔外形简洁美观，并且在一定程度上保护骨传导耳机200，避免碰撞损坏。
实施例六：
如图8所示，本实施例所述的基于骨传导耳机200的可切换发声导向方式 的骑行头盔，与实施例五所述的骑行头盔结构基本相同，其主要区别在于，还包括骨传导麦克风900以及用于连接所述骨传导麦克风900与所述头盔本体1的第二转动臂800，所述第二转动臂800具有与所述骨传导麦克风900连接的第二转动臂800第一端，以及与所述头盔本体1连接的第二转动臂800第二端，所述骨传导麦克风900通过第二转动臂800与所述头盔本体1铰接。所述第一转动臂400与所述第二转动臂800为一体式结构，通过同一铰接装置与所述头盔本体1铰接。
在本实施例中同样设置有容纳腔700，该容纳腔700为可同时容纳所述第一转动臂400以及第二转动臂800的容纳腔700结构。
由于骑行过程通常速度较快，因此骑行过程中采用传统的麦克风会由于风力影响难以保证通话质量，因此，在本实施例中采用骨传导麦克风900能够有效的避免风力干扰。
于本文的描述中，术语“第一”、“第二”，仅仅用于在描述上加以区分，并没有特殊的含义。
需要声明的是，上述具体实施方式仅仅为本发明的较佳实施例及所运用技术原理，在本发明所公开的技术范围内，任何熟悉本技术领域的技术人员所容易想到的变化或替换，都应涵盖在本发明的保护范围内。
