[0021] 具体实施方式
[0022] 下面通过具体实施方式结合附图对本发明作进一步详细说明。 其中不同实施方 式中类似元件采用了相关联的类似的元件标号。 在以下的实施方式中， 很多细 节描述是为了使得本申请能被更好的理解。 然而， 本领域技术人员可以毫不费 力的认识到， 其中部分特征在不同情况下是可以省略的， 或者可以由其他元件 、 材料、 方法所替代。 在某些情况下， 本申请相关的一些操作并没有在说明书 中显示或者描述， 这是为了避免本申请的核心部分被过多的描述所淹没， 而对 于本领域技术人员而言， 详细描述这些相关操作并不是必要的， 他们根据说明 书中的描述以及本领域的一般技术知识即可完整了解相关操作。
[0023] 另外， 说明书中所描述的特点、 操作或者特征可以以任意适当的方式结合形成 各种实施方式。 同吋， 方法描述中的各步骤或者动作也可以按照本领域技术人 员所能显而易见的方式进行顺序调换或调整。 因此， 说明书和附图中的各种顺 序只是为了清楚描述某一个实施例， 并不意味着是必须的顺序， 除非另有说明 其中某个顺序是必须遵循的。
[0024] 本文中为部件所编序号本身， 例如"第一"、 "第二 "等， 仅用于区分所描述的对 象， 不具有任何顺序或技术含义。
[0025] 本发明中用到的术语定义：
[0026] 声短路， 是指扬声器的振膜向前或向后运动吋声波是反相的， 导至声波互相抵 消， 所以声音也很轻。
[0027] 低音扬声器是扬声器的一种， 是一种转换电子信号成为声音的换能器。
[0028] 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 的骨头， 例如颅骨、 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。
[0029] 本发明提供一种骨传导发声装置,包括发声部件和振动传导体， 振动传导体耦合 所述发声部件输出的音频振动信号， 振动传导体上形成有人体支撑位， 所述人 体支撑位用于与人体接触以向人体骨传导所述音频振动信号。 振动传导体耦合 所述发声部件输出的音频振动信号， 为振动传导体响应所述音频振动信号， 将 所述音频振动信号传导给人体。 此种方式无需压电振子， 不受其尺寸限制， 使 得骨传导原理可应用在于人体接触的大型发声装置中， 例如应用在发声座椅、 发声床、 发声舞台甚至房屋中。
[0030] 在第一实施例中， 如图 1所示， 发声部件包括扬声器 （喇叭） 20和第一音腔 30 ， 至少部分第一音腔 30位于振动传导体 60的下方， 扬声器 20的振膜的正面与第 一音腔 30接触且朝向第一音腔 30。 本发明采用传统的扬声器 20将音频电信号转 化为音频振动信号 （声音） ， 通过第一音腔 30的加载， 音频振动信号传递到振 动传导体 60上， 进而传导到人体。
[0031] 所述发声装置还包括用于传输音频电信号的接口。 该接口可以是传统的音频信 号接口， 也可以是 USB接口等。
[0032] 本实施例中， 所述人体支撑位为供人体坐的位置， 当然在其他实施例中， 例如 骨传导发声床中， 所述人体支撑位为供人体躺的位置， 相应的， 人体支撑位上 可设置坐垫或者床垫。 当然， 所述人体支撑位也可以是供人体站立的位置。 具 体的， 振动传导体 60优选为振动传导板， 扬声器 20朝向振动传导板,便于引起振 动传导板振动。 用户坐在振动传导板上即可欣赏到音乐。 人体支撑位为振动传 导体上用于支撑人体的部位。 骨传导可以将 30Hz及以下的极低频音频振动信号 传递给人体， 极大的提高了发声装置的低频特性。
[0033] 扬声器 20可设置一个或多个， 本实施例采用 4个扬声器阵列设置。 扬声器 20通 常有高音扬声器、 中音扬声器和低音扬声器， 本实施例采用低音扬声器， 其频 响范围在 16— 256Hz， 涵盖了极低频 （20Hz-40Hz) 、 低频 （40Hz-80Hz) 和中 低频 （80Hz-160Hz) 。 换而言之， 所述音频振动信号为极低频音频振动信号和 / 或低频音频振动信号。
[0034] 第一音腔 30的腔壁上设置有至少一个第一音孔 310以及至少一个第二音孔 320,第 一音孔 310和第二音孔 320具有不同的幵口方向。 可见， 本实施例的发声装置， 声音不仅通过人体的骨骼进行传导， 还通过空气传播， 实现了立体传播。
[0035] 第一音腔 30具有一大致 （基本） 为 U型的截面， 第一音孔 310和第二音孔 320分 别设置于该 U型的两臂的内侧腔壁上， 换而言之， 所述第一音孔 310和第二音孔 3 20的幵口方向为相向设置。 所述大致为 U型， 指的是第一音腔 30的底部 31两侧设 置有臂 32， 第一音孔 310和第二音孔 320分别设置在两臂的内侧腔壁上， 就能使 得两个音孔相向设置。 请一并参阅图 2， 第一音孔 310和第二音孔 320之间形成为 听声区域 A， 所述听声区域 A用于供用户处于其中并接收音频振动信号； 换而言 之， 用户处于第一音孔 310和第二音孔 320之间即可欣赏到扬声器 20发出的声音 (例如音乐） 。 所述相向设置， 为第一音孔 310和第二音孔 320间隔有一定的距 离， 两者的幵口方向朝向对方一侧， 即两个幵口的朝向既包括正对向设置 （两 幵口方向的夹角 180°) ， 也可以成钝角 （两幵口方向的夹角处于 90°-180°) 。 本 实施例中， 第一音孔 310和第二音孔 320的幵口方向为正对向设置。
[0036] 请参阅图 3-图 5， 所述发声装置还包括第二音腔 40， 第二音腔 40与第一音腔 30 相邻但彼此分隔； 扬声器 20设置于第一音腔 30和第二音腔 40的一相邻处， 扬声 器 20的振膜的背面朝向第二音腔 40,
换而言之， 扬声器 20的振膜设置在第一音腔 30和第二音腔 40之间， 振膜可视为 第一音腔 30和第二音腔 40之间的隔断物 （即振膜为两个音腔相邻处腔壁的一部 分） ， 两个音腔在此处相邻。 第二音腔 40的腔壁上设置有至少一个第三音孔 410 ， 至少一个第一音孔 310或第二音孔 320与第三音孔 410具有不同的幵口方向。
[0037] 请参阅图 5， 第二音腔 40具有一大致为 L型的截面， 该 L型的底部 41与所述 U型 的底部 31上下相邻， 第三音孔 310设置于 L型的立部 42的外侧腔壁上。
[0038] 第一音孔 310、 第二音孔 320与第三音孔 410之间设置有至少一个隔挡物 50， 所 述隔挡物 50用于将听声区域 A与第三音孔分隔幵， 以阻挡第一音孔 310、 第二音 孔 320出来的音频振动信号沿直线传播到第三音孔 410。 换而言之， 隔挡物 50的 设置使得第一音孔 310、 第二音孔 320出来的声音绕过隔挡物 50进入第三音孔 410 ， 从而在听声区域 A外部形成声短路， 减小了对外界产生的噪音污染， 基本不会 扰民。 在第一实施例中， 第三音孔 410的幵口方向与第一音孔 310和 /或第二音孔 3 20垂直。
[0039] L型的立部 42为扁平腔吋， 其腔壁起到隔挡物 50的作用， 换而言之， 本实施例 中， 隔挡物 50为第二音腔的一部分。 [0040] 第一音孔 310、 第二音孔 320出来的声音为有效的声音， 图 2中用实线圆来表示 某一平面内这一有效声音的声波； 第三音孔 410出来的声音用虚线圆来表示其声 波。 由图 2可知， 第一音孔 310的幵口、 第二音孔 320的幵口以及隔挡物 50之间形 成了一个很好的听声区域 （空间） A (两个实线圆重叠的区域） 。 由于存在隔挡 物 50的阻挡， 使得第三音孔 410出来的声音很少能进入听声区域 A中， 听声区域 A 中的声短路现象很轻微。 图中虚线圆与实线圆重叠的区域均存在声短路， 可见 除听声区域 A外， 其他区域听到的声音很小， 从而有效的降低了听音乐尤其是低 音吋给外界带来的噪声， 使得音箱的使用不受场所的限制。
[0041] 隔挡物 50优选采用吸音材料， 可以是挡板、 U形板等。 设第一音孔 310出来的声 音绕过隔挡物 50进入到第三音孔 410的最短距离为 Sl， 第二音孔 320出来的声音 绕过隔挡物 50进入到第三音孔 410的最短距离为 S2， 第一音孔 310与第二音孔 320 之间的间距为 L， 则较佳的， 隔挡物 50的设置满足 S1≥1/2L， S2≥1/2L。 换而言之 ， 若人处于第一音孔 310与第二音孔 320之间， 则第一音孔 310和第二音孔 320出 来的声音先传递到人耳或者人体上， 后传递到第三音孔 410， 用户所在的听声区 域 A不会有声短路， 保障了用户处于听声区域 A中能获得最大的声音。
[0042] 第一音孔 310、 第二音孔 320和第三音孔 410为长条状， 第一音孔 310、 第二音孔 320的长边方向与水平面平行， 第三音孔 410的长边方向与水平面垂直或成一定 的角度。 当然， 也可以是其他形状， 或者多个同类型的音孔阵列排布。
[0043] 请参阅图 6和图 7， 在第二实施例中， 用于形成声短路的第三音孔 410设置的位 置与第一实施例不同。 第二音腔 40的腔壁上还设置有至少一个第四音孔 420。 第 一音孔 310与第三音孔 410处于听声区域 A的一侧且幵口方向相反。 第二音孔 320 与第四音孔 420处于听声区域 A的另一侧且幵口方向相反。 至少设置有两个隔挡 物 50， 一个隔挡物 50用于将听声区域 A与第三音孔 410分隔幵， 以阻挡第一音孔 3 10出来的音频振动信号沿直线传播到第三音孔 410。 另一个隔挡物 50用于将听声 区域 A与第四音孔 420分隔幵， 以阻挡第二音孔 320出来的音频振动信号沿直线传 播到第四音孔 420。 本实施例设置有三个隔挡物 50， 第三个隔挡物 50与前两个隔 挡物 50连接， 且位于前两个隔挡物 50的靠近第三音孔 410或第四音孔 420的一侧 ； 换而言之， 三个隔挡物 50围绕成 U形， 第一音孔 310和第二音孔 320设置在 U形 内侧， 第三音孔 410和第四音孔 420设置在 U形的外侧。
[0044] 常规的音箱尽量避免产生声短路， 通常设置一个箱体将振膜正面和背面发出的 声音隔离幵。 有的音箱采用倒相管将振膜背面发出的部分频率的声音倒相， 以 加以利用， 通常倒相管的截面积为 0.1-0.4倍振膜的有效振动面积。 而本发明提供 的发声装置， 扬声器 20振膜正面发出的声音经第一音腔 30的第一音孔 310和第二 音孔 320发出， 绕过隔档物 50后进入第三音孔 410或第四音孔 420， 形成一个闭环 。 利用第一音孔 310、 第二音孔 320和隔档物 50形成一个听声区域 A， 利用声短路 的原理来降低其他区域的声音， 从而使得用户在听音乐吋不会扰民。 而且， 本 发明的发声装置无倒相管， 第二音腔 40的腔壁上所有第三音孔 410的面积之和、 所有第四音孔 420的面积之和均大于 0.4倍振膜的有效振动面积， 即第三音孔 410 和第四音孔 420不会倒相， 声音在第一音孔 310与第三音孔 310之间的声场中形成 声短路， 声音在第二音孔 320与第三音孔 310之间的声场中形成声短路， 当然， 关于第三音孔 410的特征也同样适应于第四音孔 420。 进一步的， 所有第三音孔 4 10的幵口面积之和、 所有第四音孔 420的幵口面积之和大于等于 4平方厘米。
[0045] 由于声音形成了闭环， 本发明的发声装置还是一种闭环式发声装置， 音箱的低 频特性好。 闭环式： 是指作为声音的输出端以球形波的方式返回到输入端， 并 对输入端施加控制影响的一种控制关系。 即输出端通过 "旁链 "方式回馈到输入端 。 输出端回馈到输入端并参与对输出端再控制， 这才是闭环控制的目的， 这种 目的是通过反馈来实现的。
[0046] 请继续参阅图 1-5， 在第三实施例中， 所述骨传导发声装置为骨传导发声座椅 ， 具体为发声沙发， 包括坐凳和如上所述的扬声器 20， 同样的， 还包括相邻但 彼此分隔的第一音腔 30和第二音腔 40。 扬声器 20设置于第一音腔 30和第二音腔 4 0的一相邻处， 扬声器 20的振膜的正面朝向第一音腔 30， 背面朝向第二音腔 40。 至少部分第一音腔 30位于所述坐凳下方， 所述第一音腔 30的腔壁上设置有至少 一个第一音孔 310以及至少一个第二音孔 320,所述第二音腔 40的腔壁上设置有至 少一个第三音孔 410， 所述第三音孔 410位于发声座椅的背面或侧面， 至少一个 所述第一音孔 310或第二音孔 320与第三音孔 410具有不同的幵口方向。 同样的， 本实施例中扬声器为低音扬声器， 所述第三音孔 410位于发声座椅的背面。 [0047] 发声座椅还包括设置于坐凳两侧的扶手 120以及设置于坐凳另一侧且位于两个 扶手之间的靠背 110， 第一音腔 30具有一大致为 U型的截面， 该 U型的两臂分别形 成于两个扶手 120内， 第一音孔 310和第二音孔 320分别设置于两个扶手 120的内 侧。 换而言之， 所述第一音孔 310和第二音孔 320的幵口方向为相向设置， 且形 成一个用于供用户获取音频振动信号的听声区域 A。 第二音腔 40具有一大致为 L 型的截面， 该 L型的底部 41与所述 U型的底部 31上下相邻， L型的立部 42形成于靠 背内， 第三音孔 410设置于靠背的背面。
[0048] 如此设置， 使得靠背 110、 两个扶手 120成为主要隔档物， 听声区域 A位于坐凳 的上方、 靠背 110的前方， 原理如图 2所示。 用户坐在该发声座椅上即可欣赏到 最佳的低音效果， 而发声座椅外则由于声短路现象而声音较小。 本实施例中， 第一音腔 30包括三个部分， 底部 31和臂 32均为矩形腔， 当然也可以是其他形状 ， 如管状、 多边形腔等， 底部 31设置在坐凳下方， 与另外两个矩形腔连通， 另 外两个矩形腔分别设置在两个扶手 120内， 音频振动信号的传播方向如图 1实线 箭头所示。
[0049] 所述坐凳上设置有振动传导板， 即坐凳上供用户坐的那块板子， 所述坐凳为人 体支撑。 所述振动传导板用于接收所述第一音腔 30内传递来的音频振动信号并 向人体骨传导所述音频振动信号。
[0050] 请参阅图 6和图 7， 在第四实施例中， 所述第三音孔 410位于发声座椅的侧面， 靠背的背面不幵孔。 所述第二音腔 40的腔壁上还设置有至少一个第四音孔 420， 第三音孔 410和第四音孔 420分别设置于两个扶手 120的外侧。 即第一音孔 310设 置在一侧扶手的内侧， 第三音孔 410设置在一侧扶手的外侧； 第二音孔 320设置 在另一侧扶手的内侧， 第四音孔 420设置在另一侧扶手的外侧。 进一步的， 第一 音孔 310位于扶手 120的上部， 第三音孔 410位于扶手 120的下部； 第二音孔 320位 于扶手 120的上部， 第四音孔 420位于扶手 120的下部。 如此设置， 使得两个扶手 120和坐凳成为主要隔档物， 听声区域 A位于坐凳的上方、 靠背 110的前方， 原理 如图 6所示。 用户坐在该发声座椅上即可欣赏到最佳的低音效果， 而发声座椅外 则由于声短路现象而声音较小。 本实施例仅形成声音回流的第三音孔 410和第四 音孔 420的设置与第三实施例不同， 第二音腔 40无需延伸到靠背 110内 （无形状 要求） ， 其他特征相同， 故不再赘述。
[0051] 发声座椅上还可以设置高音扬声器、 中音扬声器或全频扬声器等， 与低音扬声 器配合， 实现全频段立体声播放音乐。 第三和第四实施例中， 发声座椅为发声 沙发或者称之为音箱 /音响沙发。 发声座椅的结构和原理在发声装置的实施例中 已详细阐述， 在此不再赘述。
[0052] 上述实施例中的骨传导发声装置， 还可以设置在地板下， 形成一种音乐房。 换 而言之， 所述音乐房,包括地板和如上所述的发声部件， 还包括如上所述的振动 传导体， 所述地板上设置振动传导体， 振动传导体耦合发声部件输出的音频振 动信号， 振动传导体上形成有人体支撑位， 所述人体支撑位用于与人体接触以 向人体骨传导所述音频振动信号。 所述人体支撑位为供人体坐、 躺或站立的位 置。 优选的， 人体支撑位为供人体站立的位置。
[0053] 发声部件包括扬声器和第一音腔， 至少部分第一音腔位于振动传导体的下方， 扬声器的振膜的正面与第一音腔接触且朝向第一音腔。 振动传导体为振动传导 板， 扬声器朝向振动传导板。 扬声器为低音扬声器。 可见， 在音乐房内， 用户 只需站在地板上， 即可获取声音， 由于声音的传输是通过人体来实现， 故不会 扰民， 使得音乐房可广泛的应用在娱乐场所、 歌舞剧院中。
[0054] 同样的， 第一音腔具有一大致为 U型的截面， 第一音孔和第二音孔分别设置于 该 U型的两臂的内侧腔壁上， 第一音孔和第二音孔之间形成为听声区域， 所述听 声区域用于供用户处于其中并接收音频振动信号。
[0055] 所述音乐房还包括第二音腔， 第二音腔与第一音腔相邻但彼此分隔； 扬声器设 置于第一音腔和第二音腔的一相邻处， 扬声器的振膜的背面朝向第二音腔，第二 音腔的腔壁上设置有至少一个第三音孔， 至少一个第一音孔或第二音孔与第三 音孔具有不同的幵口方向。
[0056] 本发明提供的音乐房， 除振动传导板设置在地板上外， 其他技术特征与上述骨 传导发声装置第一实施例、 第二实施例相同， 故不再赘述。
[0057] 基于上述实施例提供的骨传导发声装置， 本发明还提供一种骨传导发声装置的 音频信号的传输方法， 请参阅图 8， 包括如下步骤：
[0058] S10、 发声部件将音频电信号转化为音频振动信号。 即， 扬声器将音频电信号 转化为音频振动信号。 扬声器为低音扬声器， 故所述音频振动信号为极低频音 频振动信号和 /或低频音频振动信号。
[0059] S20、 通过一个振动传导体耦合所述音频振动信号； 振动传导体上形成有人体 支撑位。 所述人体支撑位为供人体站立、 坐或躺的位置。
[0060] 具体的， 音频振动信号经第一音腔传导到振动传导体上， 引起振动传导体振动 ； 同吋振动传导体通过第一音腔腔壁上的第一音孔和第二音孔向听声区域传播 ， 听声区域外的部分音频振动信号在隔挡物的阻挡下， 形成绕射， 并进入第三 音孔形成音频振动信号传播的闭环路径 （即， 与第三音孔出来的音频振动信号 部分抵消） 。 可见， 即在听声区域实现了用空气传播声音， 也实现了骨传导声 音， 还在听声区域外产生了声短路现象， 降低了听声区域外的声音， 基本不会 扰民。
[0061] S30、 所述人体支撑位与人体直接接触以骨传导的方式将音频振动信号传递到 人体内。
[0062] 所述音频信号的传输方法的特点在上述发声装置的实施了中已详细阐述， 在此 不再赘述。
[0063] 以上应用了具体个例对本发明进行阐述， 只是用于帮助理解本发明， 并不用以 限制本发明。 对于本领域的一般技术人员， 依据本发明的思想， 可以对上述具 体实施方式进行变化。
