上盖2具有贯穿的多个第二散热开口21，第二散热开口21包括第二开口22及多个第二散热孔23，该第二开口22位于该上盖2的中部，多个第二散热孔23围绕第二开口22排成一圈或多圈，该第二开口22的内径可以较第二散热孔23的内径大。
支撑体3包括安装部31及悬挂部32，该安装部31和主体壳1固定连接，该安装部31面向上盖2的一侧设有安装槽33，该悬挂部32具有弹性，该悬挂部32具有连接端34和自由端35，该连接端34与安装部31固定连接，该连接端34可以有一个或多个，该自由端35在受到外力时能够产生变形，该自由端35也可以有一个或多个，如自由端35可以为环形，如圆环形、方环形、多边形环形等。悬挂部32可以有独立设置的多个，每个悬挂部32均具有挂接磁轭结构体的自由端35和与安装部31固定连接的连接端34，悬挂部如弹簧。
磁轭结构体4包括能够形成磁通闭路的轭铁41、轭构件42及磁铁43，该轭铁41面向主体壳1的一侧凹设有固磁槽44，磁铁43和轭构件42均装入该固磁槽44，轭铁41和轭构件42夹住该磁铁43，磁铁43与固磁槽44的槽底固定，轭构件42与磁铁43固定，且固磁槽44的槽壁、磁铁43的外周面、轭构件42的外周面之间形成环状空隙45。
线圈骨架5为轴向贯穿的管状体，如圆管、方管、多边形管或其他形状。该线圈骨架具有配合部51和位于配合部下方的结合部52，该结合部52由隔热材料制成，如由非金属材料或其他能够起到隔热效果的材料制成，该配合部51由导热材料制成，如由铝等金属材料或其它能够起到导热效果的材料制成，该结合部52用于与主体壳1固定连接，该配合部51用于与线圈6配合。
线圈6与导线7连接，该导线7用于向线圈6提供电信号。
主体壳1和上盖2可以由耐高温的塑胶材料制成，线圈骨架5的结合部52可以由耐高温的隔热材料制成，线圈6通电发热时，热量会部分传递到主体壳、上盖和线圈骨架的结合部52上，由于材料耐高温，可以尽量减小主体壳、上盖、线圈骨架被熔融损坏的可能。
振动换能器组装时，将磁铁43的上端面固定在轭铁的固磁槽44的槽底，将轭构件42固定在磁铁43的下端面，形成磁轭结构体4；通过第一螺纹紧固件8锁紧轭铁41和支撑体的悬挂部32，使磁轭结构体4悬挂在支撑体3的下方；将线圈骨架的结合部52固定在主体壳的定位槽14内，将线圈6绕在线圈骨架的配合部52上，连接线圈的导线7穿过主体壳的过线孔15；通过第二螺纹紧固件9锁紧主体壳1和支撑体的安装部31，使主体壳1和支撑体3固定连接一体；将上盖2嵌入支撑体3的安装槽33。组装后，磁轭结构体4、支撑体3位于上盖2和主体壳1之间，磁轭结构体4位于主体壳的壳腔18内，线圈6伸入磁轭结构体的空隙45内。
振动换能器使用时，通过导线7给线圈6提供电信号，线圈6切割磁铁43的磁力线，因为磁轭结构体4悬挂在支撑体3的可变形的悬挂部32上，使磁轭结构体4和主体壳1的相对位置发生变化，磁轭结构体4在主体壳1的轴向上上下振动，从而产生体感振动。
如图11及图12所示，其为线圈骨架的第二具体实施方式。该线圈骨架5的结合部52和自由部51均由隔热材料制成。
主体壳的第一散热开口11的形状、大小、数量及分布可以根据散热要求设计，如图13至图15所示。
振动换能器包括主体壳、上盖、磁轭结构体、线圈骨架及线圈，主体壳、上盖及磁轭结构体固定连接一体，磁轭结构体悬挂在支撑体下方，线圈绕在线圈骨架上，线圈骨架具有由隔热材料制成的结合部，该结合部与主体壳固定，且主体壳和上盖中至少之一设有散热开口。通过设置隔热的结合部，可以减少或避免线圈的热量直接传递到主体壳而由主体壳直接散热，而是利用空气的流动，使热量尽量多的通过散热开口散热，散热效率高，同时，由于热量较多的通过散热开口散热，使热量较少的传递到磁轭结构体上，使磁轭结构体不易过热。当主体壳和上盖均设有散热开口时，更利于振动换能器内部的空气流动，更容易散热。主体壳和上盖的散热开口的形状、大小、数量及分布可以根据散热要求设计。
为了便于定位线圈骨架，可以在主体壳上设置定位槽。由于线圈的热量主要通过空气流动散热，而不是通过线圈骨架传递到主体壳上，降低了线圈骨架结合部和主体壳的装配要求，便于生产流水线操作。
为了便于组装振动换能器，可以在主体壳上设置过线孔，这样，连接线圈的导线就不需要经过主体壳和上盖结合的部位，在组装时，可以先把导线和线圈连接好再安装上盖，简化了组装工艺，同时，在打开上盖时，不会牵扯到导线，也方便维修。
为了避免磁轭结构体和支撑体的连接处受到振动次数和温度升高的影响，磁轭结构体和支撑体可以通过螺纹紧固件连接，使两者之间的连接更为牢固。
由于线圈的散热主要通过空气流动散热，所以，主体壳和上盖可以由塑胶材料制成。从而降低了制造成本。
对于振动换能器，主体壳和上盖构成壳体，磁轭结构体、支撑体、线圈骨架和线圈位于该壳体内。主体壳和上盖可以为前述结构，也可以为现有结构，或者其它能够放置磁轭结构体、线圈和线圈骨架的结构。磁轭结构体可以为前述结构，也可以为现有结构，或者其它具有磁铁并能被线圈切割磁力线的结构。支撑体可以为前述结构，也可以为现有结构，或者其它能够挂接磁轭结构体并在线圈通电时能够使磁轭结构体上下振动的结构。线圈骨架可以整体由隔热材料制成，也可以仅其与主体壳连接的部位由隔热材料制成。
一种体感振动装置，包括载体和振动换能器，该振动换能器置于该载体的内部。该体感振动装置如具有振动换能器的头部按摩器、眼部按摩器、按摩椅、按摩坐垫、按摩沙发等。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
