图2为本申请实施例提供的喇叭的结构示意图，图3为本申请实施例提供的喇叭的拆分结构示意图，如图2和3所示，本实施例提供了一种喇叭，其主要包括壳体1、底座5、喇叭网7、喇叭本体3和喇叭支架2。壳体1和底座5形成用于安装喇叭本体3和喇叭支架2的容置腔，并形成喇叭的外观面；喇叭本体3为电声换能器件，用于将喇叭后端穿入的声信号转换成电信号，经放大后转换成声信号从喇叭前端扩散传出，或将外部输入的电信号放大后转换成声信号经喇叭前端扩散传输；喇叭支架2设置在容置腔内，用于安装喇叭本体3，并形成位于喇叭本体3前端的前音腔和位于喇叭本体3后端的后音腔；喇叭网7设置在底座5上，用于将声信号扩散传出至喇叭外部。
在本实施例中，某个结构的前端和后端均以喇叭整体为参考，即：对于喇叭而言，喇叭的扩口端为喇叭前端，喇叭的小口端为喇叭后端；对于设置在喇叭内的部件而言，该部件的前端为靠近喇叭前端的一端，该部件的后端为靠近喇叭后端的一端。
图4为本申请实施例提供的喇叭的剖视图，图5为图4中I处的局部放大图，如图2-5所示，喇叭本体3为喇叭的电声换能器件。在本实施例中，喇叭本体3采用锥形纸盘式结构，其主要包括音圈31、锥形纸盘34、框架36、振膜折环33、磁铁32、定芯支片等结构。其中，音圈31是喇叭本体3的驱动单元，其与锥形纸盘34固定在一起，当声音电流信号通过音圈31后，音圈31振动带动纸盘振动；锥形纸盘34是喇叭本体3的声音辐射器件，在较大程度上决定喇叭本体3的放声性能；振膜折环33连接在锥形纸盘34的前端，用于保证锥形纸盘34沿喇叭本体3的轴向运动且限制锥形纸盘34沿喇叭本体3的径向运动；定心支片35设置在音圈31和锥形纸盘34之间，用于支撑音圈31和锥形纸盘34的结构部分，保证其垂直而不歪斜。
框架36包括空心圆台状的支撑部361和板状的连接部362，振膜折环33、锥形纸盘34、定心支片35以及音圈31位于支撑部361的内部，磁铁32的一端伸出支撑部361的后端并通 过固定件与框架36固定。连接部362垂直于喇叭本体3的轴线方向，且连接部362由支撑部361的前端边缘沿垂直于喇叭本体3的轴向方向向外延伸形成，用于实现喇叭本体3与外部结构的连接。
在本实施例中，喇叭本体3可以采用现有的市售产品，且喇叭本体3的结构和喇叭本体3的发声原理为本领域的常规设置，本实施例不再详细赘述。且在其他实施例中，喇叭本体3还可以采用其他结构的结构类型。
为实现喇叭本体3在喇叭内部的安装，喇叭内部设置有喇叭支架2，且为提高喇叭本体3的出音品质，在本实施例中，喇叭支架2包括分体设置的前支架21和后支架22。前支架21具有前端开口的前腔体212，且前支架21的后端端板211上开设有与前腔体212连通的安装口214；后支架22具有前端开口的后腔体221，且后支架22的前端与前支架21的后端端板211密封连接，同时，后腔体221在前支架21后端端板211上的投影覆盖安装口214。
安装口214用于安装喇叭本体3，喇叭本体3的后端穿过安装口214，使框架36的支撑部361位于后腔体221，且框架36的连接板位于前腔体212中且与前支架21的后端端板211连接，同时，喇叭本体3与安装口214密封连接，以使前支架21的前腔体212和后支架22的后腔体221不连通。
本实施例提供的喇叭，通过采用分体设置的前支架21与后支架22，使后支架22中的后腔体221的设置不受限于喇叭本体3的安装以及喇叭支架2的成型工艺，能够增大后腔体221的空间，从而增大喇叭的后音腔的空间，避免声短路，从而使喇叭能够表现出更好的低音效果，改善喇叭的出音效果。
本实施例中，前支架21与后支架22可拆卸连接，以方便喇叭支架2的组装和更换。在其他实施例中，前支架21和后支架22也可以采用超声连接、粘接等方式连接形成喇叭支架2。
为减小喇叭本体3与喇叭支架2的振动以及提高喇叭本体3与喇叭支架2支架的密封性，连接部362的后端面与前支架21后端端板211之间可设置有第二密封件37。第二密封件37可选为与连接部362的形状相一致并覆设在连接部362的后端面上，以进一步提高喇叭本体3与喇叭支架2支架的减震效果和密封性能。在本实施例中，第二密封件37可采用硅胶支撑，也可以采用EVA(乙烯-醋酸乙烯共聚物，ethylene-vinyl acetate copolymer)或其他具有弹性和密封性的材质制成。
在本实施例中，支撑部361的前端边缘沿垂直于喇叭本体3的轴向方向向外延伸有凸缘， 凸缘的外侧边向前端垂直延伸有延伸部，延伸部的前端沿垂直于喇叭本体3的轴向方向向外延伸形成有上述的连接部362。第二密封件37包括包覆连接部362后端面的第一部371和包覆凸缘后端面的第二部372。在安装口214的内侧壁设置环形凸台，使安装口214的后端口径小于前端口径，以使安装口214内形成与连接部362平行的限位台阶面。当喇叭本体3与喇叭支架2安装时，限位台阶面与第二部372抵接，前支架21后端面的下表面与第一部371抵接，能够进一步提高喇叭本体3与喇叭支架2之间的安装稳定性以及两者之间的连接密封性。
在本实施例中，喇叭本体3与前支架21采用螺纹连接，以提高喇叭本体3与前支架21之间的连接稳定性，减小两者之间的相对振动。为方便连接，连接部362和第二密封件37均为具有中心孔的板状结构，其四角开设有连接孔，前支架21的后端端板211上开设有螺纹孔，螺纹孔与连接孔对应设置，且通过螺纹连接件连接。前支架21的后端端板211向外凸垂直凸设有第一连接柱215，螺纹孔深入第一连接柱215中，以提高螺纹连接件的连接长度，从而在保证前支架21的较小壁厚的同时，提高喇叭支架2与前支架21的连接稳定性。在其他一个实施例中，喇叭本体3上的连接部362可以为其他形状，如圆板状等。在其他另一个实施例中，喇叭本体3与前支架21还可以采用其他可拆卸的方式连接。
在本实施例中，前支架21和/或后支架22均为前端大、后端小的空心圆台状结构，以使前腔体212和/或后腔体221的后端至前端的口径逐渐增大，以提高喇叭前音腔和/或后音腔的调音效果，改善喇叭的出音品质。后腔体221的最小横街面面积大于或等于安装口214的横截面面积，以尽可能地增大后音腔的空间，改善喇叭的出音品质。
在本实施例中，为增大后音腔的体积，后支架22的前端面积基本等于或略小于前支架21的后端端板211面积。可选的，后支架22的侧面锥度基本与壳体1对应处的侧面锥度平行，以在保证喇叭支架2在壳体1内安装的同时，尽可能提高后支架22沿垂直于喇叭本体3轴向方向的尺寸，从而尽可能增大后腔体221的尺寸，即增大后音腔的尺寸。
在本实施例中，为进一步提高喇叭的出音品质，后支架22的后端设置有与后腔体221连通的振动膜4。后支架22具有后端开口，振动膜4设置在后端开口处并封闭后端开口。振动膜4的设置，能够随声波在后音腔的传播而振动，从而改善声波在后音腔中的传播，提高喇叭的出音效果。同时，振动膜4的设置，能够减小喇叭本体3、喇叭支架2与壳体1之间的相对振动，改善整机的振动效果，进一步提高喇叭的出音品质。
为方便振动膜4在后支架22上的安装，在本实施例中，后支架22的后端边缘向内延伸 形成有安装凸台223，安装凸台223的外表面沿轴向方向垂直凸设有限位筒部224。振动膜4的下表面粘接在安装凸台223的外表面上，且振动膜4的外壁面与限位筒部224的内侧壁抵接。
在本实施例中，振动膜4为薄片状结构，且靠近外缘的部分沿朝向喇叭本体3的方向凸设形成振动凸部41，振动凸部41位于安装凸台223的内侧。振动膜4的结构设置和材料选型为本领域的常规技术手段，本实施例不再进行赘述。
在本实施例中，前支架21与后支架22之间可选采用螺纹连接。后支架22的前端边缘沿其径向向外凸设有连接耳222，且连接耳222沿后支架22的周向均匀间隔设置有多个。连接耳222上设置有连接孔，前支架21对应连接孔的位置开设有螺纹孔，螺纹孔与连接孔配合设置且一一对应，连接孔与螺纹孔之间通过螺纹连接件螺纹连接。在其他实施例中，前支架21与后支架22也可以采用卡接、插接等其他可拆卸的连接方式。
前支架21的后端端板211的前后两面上对应连接孔的位置均垂直凸设有第二连接柱216，螺纹孔从后端第二连接柱216延伸至前端的第二连接部216中，以提高螺纹连接件的连接深度，从而提高后支架22与前支架21的连接稳定性。在其他实施例中，也可以是仅在后端端板211的外表面设置第二连接柱216或在后端端板211的内表面设置第二连接柱216。
为提高前支架21与后支架22之间的连接密封性，在本实施例中，前支架21的前端面与后支架22的后端面之间设置有第一密封件6。后支架22的后端端板211上开设有环形的密封槽，密封槽内安装有环形的第一密封件6，当前支架21与后支架22安装时，第一密封件6受密封槽槽底和前支架21挤压而产生密封作用。在本实施例中，第一密封件6采用硅胶条，具有较好的防水防尘等密封性能，在其他实施例中，第一密封件6还可以采用其他材质设置，且第一密封件6的设置和材料选型为本领域的常规技术手段，本实施例不再进行赘述。
在本实施例中，为对喇叭进行封装并使其具有较好的外观面，喇叭本体3和喇叭支架2均设置在壳体1内部。壳体1为薄壳空心结构，其具有前端开口的容纳腔11，且容纳腔11的横截面面积沿后端至前端逐渐增大，以适配喇叭支架2的外形结构，并达到扩音效果。可选的，形成旋转式壳体1的母线为开口朝外的弧形线，且弧形线的切线与壳体1轴线之间的夹角沿后端至前端逐渐减小，以提高壳体1外观的美观性。在其他实施例中，形成旋转式壳体1的母线还可以为与壳体1轴线倾斜的直线，本申请对壳体1具体结构形式不做限定。
在本实施例中，喇叭支架2与壳体1采用可拆卸连接，以方便喇叭的组装、维修和更换。可拆卸连接方式为螺纹连接。壳体1前端内壁上沿其轴向方向凸设有第三连接柱，第三连接 柱沿轴向开设有螺纹孔。前支架21的侧壁对应第三连接柱的位置沿沿其轴向向外凸设有第四连接柱，第四连接柱上开设有贯穿第四连接柱和前支架21侧壁的连接孔，连接孔与螺纹孔之间通过螺纹连接件连接。第三连接柱和第四连接柱的设置，能够在保证壳体1和前支架21的壁厚的同时，提高壳体1与喇叭支架2的连接稳定性和可靠性。在喇叭支架2与壳体1安装时，螺纹连接件通过前支架21的前端开口拧入壳体1中。在其他实施例中，喇叭支架2与壳体1还可以采用卡接、插接等其他的连接形式。
图6为本申请实施例提供的喇叭在第二方向的剖视图，图7为图5中J处的局部放大图如，如图6和7壳体1的前端连接有底座5和喇叭网7，以封闭壳体1的前端开口。在本实施例中，底座5包括底板部51和外接部52，底板部51为垂直于喇叭轴线的板状结构，且其形状与壳体1的前端开口形状相适配。底板部51的后端面上沿其边缘开设有第一安装槽511，壳体1前端端面沿其边缘开设有第二安装槽121，第一安装槽511和第二安装槽121对应设置，且喇叭网7的前端卡入第一安装槽511中，喇叭网7的后端卡入第二安装槽121中。
上述设置方式，由于喇叭网7的两端分别卡在底座5的底板部51和壳体1上，提高了喇叭网7的安装稳定性，减小喇叭网7与壳体1及底座5之间的装配误差和装配间隙，从而提高喇叭的出音品质；且由于不需要使喇叭网7包覆底座5的侧壁和底部边缘，喇叭网7可以由板状网料经过一次性弯折形成，大大降低喇叭网7成型工艺，提高喇叭网7的成型良率和生产效率；且由于喇叭网7结构和加工简单，能够使喇叭网7的适用材质由常规的铁材扩展至铝材等金属材质，喇叭网7的外形处理工艺能够得到扩展，增加喇叭网7的颜色种类的多样性和可选性，提高喇叭网7的外形美观性；再者，由于喇叭网7的前后边缘分别被壳体1和底座5包裹，不需要在底座5前端设置底板结构对喇叭网7进行遮挡，简化喇叭的结构复杂性，进一步提高喇叭外形美观性和装配便利性。
在本实施例中，喇叭网7为具有开口的圆台面形，其大端与壳体1连接，小端与底座5连接。在其他一个实施例中，喇叭网7还可以为具有开口的圆柱面形，在其他另一个实施例中，喇叭网7还可以为异形结构，只要喇叭网7的形状与壳体1和底座5的边缘形状相适配即可。
在本实施例中，壳体1的前端边缘沿其轴向向下延伸有挡缘12，挡缘12的端面上开设有上述的第二安装槽121。挡缘12的设置，一方面方便第二安装槽121的开设，另一方面可以对前支架21的前端边缘起到止挡定位作用。为了方便第一安装槽511的开设，底板部51的边缘沿朝向壳体1的方向凸设有安装凸缘512，安装凸缘512的端面上开设有上述第一安装槽511。
在本实施例中，喇叭网7的后端与第二安装槽121的槽底抵接，且喇叭网7的内表面与第二安装槽121的内侧槽壁抵接；喇叭网7的前端与第一安装槽511的槽底抵接，且喇叭网7的外表面与第一安装槽511的外侧槽壁抵接，以提高喇叭网7在第一安装槽511和第二安装槽121内的安装稳定性，从而提高喇叭网7与壳体1及底座5的连接稳定性。
在本实施例中，喇叭网7的两端之间形成有开口，即喇叭网7的侧壁未封闭的结构，其开口处用于设置外接部52。即，外接部52沿底板部51的边缘设置在底板部51的后端面上，且外接部52的前端与底板部51连接，其后端与壳体1连接。第一安装槽511的两端分别位于外接部52的两端附近。外接部52的设置，可以用于在底座5上设置USB端口、DC电源端口、耳机端口等外接口522，以方便喇叭与外界设备的连接。在其他实施例中，当喇叭不需要与外界设备连接时，喇叭网7也可以为两端封闭的结构，此时，第一安装槽511和第二安装槽121的两端相连。
在本实施例中，为提高喇叭的外观美观性，外接部52的两端分别沿底座5的周向向外延伸有止挡部521，第一安装槽511的两个端部分别位于对应的止挡部521的内侧。当喇叭网7的后端卡入第一安装槽511后，喇叭网7的两端分别位于对应的止挡部521的内侧，能够防止喇叭网7露出底座5外部，提高喇叭网7与底座5之间的连接稳定性以及喇叭的结构美观性。止挡部521与第一安装槽511的外侧槽壁平齐，使喇叭网7端部的外表面与止挡部521的内表面抵接，进一步提高对喇叭网7的连接定位作用，防止喇叭网7脱离出第一安装槽511。
在本实施例中，喇叭网7的外表面与外接部52的外表面形成完整的圆台面，以提高喇叭的外形美观性。
在本实施例中，为提高喇叭的出音品质，底板部51对应喇叭本体3的位置沿朝向喇叭本体3的方向凸设有导音锥53。且导音锥53的小端朝向喇叭本体3，导音锥53的轴线与喇叭本体3的轴线重合。导音锥53的设置，能够有效地改变声音的折射角度，使声音能够沿导音锥53的周向向四周辐射，减小声音因反射而造成的减弱，改善喇叭的高频音质，提高喇叭的出音效果。由于本实施例中，底板部51为圆形，导音锥53设置在底板部51的中心，以使导音锥53的轴线与喇叭本体3的轴线重合，以提高导音锥53对喇叭本体3出声的辐射效果。在本实施例中，导音锥53由底板部51沿其轴向方向向喇叭本体3的方向挤压加工形成，使导音锥53与底板部51一体成型，简化底板部51的结构，方便底板部51和导音锥53的加工。
在本实施例中，为提高底座5与壳体1的连接和定位准确性，底板部51的后端面垂直凸设有第一定位柱54，第一定位柱54上开设有定位槽，前支架21的内侧表面沿轴向凸设有第 二定位柱213，第二定位柱213伸入定位槽中，并与定位槽的槽底抵接，实现喇叭支架2与底座5之间的连接定位，从而实现底座5、喇叭支架2及壳体1的连接定位。
第一定位柱54内还开设有穿接孔，穿接孔贯穿底板部51的前端端面，且穿接孔位于定位槽的前侧，且两者之间通过直径较小的连接孔连通。第一定位柱54内开设有与连接孔适配的螺纹孔，螺栓等螺纹连接件通过穿接孔实现第一定位柱54和第二定位柱213之间的螺纹连接，进一步提高喇叭支架2与底座5的连接稳定性和可靠性，从而使喇叭各部分之间均可靠地连接在一起。
在本实施例中，第一定位柱54设置在底板部51靠近外侧的位置，以避免第一定位柱54的设置影响导音锥53的导音效果。在本实施例中，第一定位柱54沿底板部51的周向均匀间隔设置有六个，在其他实施例中，第一定位柱54的个数可以根据需求自行设置。
在本实施例中，底板部51的前端面设置有脚垫，以增大底板部51与外部结构之间的摩擦。脚垫为弧形结构，且其沿底板部51的周向间隔设置有多个。
本申请还提供了一种直播镜，包括支撑座、镜架、镜体和摄像装置。支撑座上设置有上述的喇叭，镜架设置在支撑座上，镜体与镜架连接，且摄像装置设置在镜体上。本实施例提供的直播镜，通过设置上述的喇叭，能够提高直播镜的出音效果。
