附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，而描述中的附图是本发明的一些实施例，对于本领域普通技术人员来说，在不付出创造性劳动的前提下，还可以根据这些附图获得其他附图。
图1是带麦克风的智能头盔实施例电气框图。
图2是带麦克风的智能头盔实施例结构示意图。
图3是接触支架实施例结构示意图。
图4是接触支架另一实施例结构示意图。
下面结合实施例，并参照附图，对本发明目的的实现、功能特点及优点作 进一步说明。
具体实施方式
为了使发明的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1和图2所示，本发明提供一种带麦克风的智能头盔实施例。
该带麦克风的智能头盔包括：头盔主体A和设于头盔主体A内的控制模块1，以及与控制模块1连接的无线传输模块3，在头盔主体A的帽檐内侧设有与用户额骨、颧骨或声带接触的骨传导麦克风2，该骨传导麦克风2与控制模块1信号连接。
具体地说，所述骨传导麦克风2采用现有技术。所述控制模块1用于控制和协调无线传输模块3与移动终端无线连接，同时使骨传导麦克风2通过用户说话时声音的振动转为电信号通过无线传输模块3传输。所述无线传输模块3可以采用现有技术实现将骨传导麦克风2输入的语音电信号以无线的方式传输至移动终端，实现由移动终端进行输出；或者由移动终端将接收到的骨传导麦克风2输入的语音电信号传输到另一个移动终端或音频输设备进行输出，实现通过头盔进行通讯。所述无线传输模块3包括蓝牙模块、WIFI模块或GPRS模块等。
使用时，由于骨传导麦克风2与用户的额骨、颧骨或声带紧密接触，用户说话时振动通过额骨或颧骨传导到骨传导麦克风2，由骨传导麦克风2将振动信号转为电信号，输给控制模块1，再由无线传输模块3将骨传导麦克风2输入的信号发送给与智能头盔信号连接的移动终端，最后由与移动终端信号连接的另一个移动终端进行输出，实现与另一个用户实现语音通讯。避免在背景噪声较大的场所使用头盔进行语音通话时出现噪声过大，影响通话效果，提高头盔使 用的适用性，减少使用场所环境对其影响。
由于用户的头大小不同，为了更了适应不同用户需要，所述头盔内侧设有使骨传导麦克风与用户紧密接触的接触支架，如图3所示。所述接触支架包括设有骨传导麦克风的弹性压杆7，所述骨传导麦克风2设置在弹性压杆7的端部，在用户戴上头盔后，弹性压杆7使骨传导麦克风2能与用户的额骨紧密接触，更好传导说话时产生的振动。在所述弹性压杆7可以在与头盔内侧转动连接，在头盔主体与弹性压杆7之间设有复位部件8，如弹簧或弹片等，在使用时可以使骨传导麦克风2有第二次位置微调，起到调节骨传导麦克风2与人身接触的力度，提高佩戴的舒适性。
如图4所示，所述接触支架还可以包括至少一连接杆6，该连接杆6的一端与头盔内侧固定，另一端与固定座4连接，在该固定座4上设有骨传导麦克风2。由于连接杆6通常采用具有一定弹性的材料，初始状态时，固定座4处于自由状态向头盔内侧突出，当用户戴上头盔时，挤压到固定座4上的骨传导麦克风2，使得固定座4向外移动，在连接杆6作用下，通过适应设置能使骨传导麦克风2与用户的额骨紧密接触，更好传导说话时产生的振动。所述固定座4内设有使骨传导麦克风2受压复位的海绵5或弹簧，通过海绵5或弹簧可以使骨传导麦克风2有第二次位置微调改变，起到调节骨传导麦克风2与人身接触的力度，提高佩戴的舒适性。所述连接杆6设有形变复位的U形或M形复位结构61，通过复位结构61适当调节连接杆6形变的受力强度，增加骨传导麦克风2与用户的额骨紧密接触时的力度，进一步达到增加佩戴的舒适性。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，而这些修改或替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
