为了解决现有技术中存在的问题，本发明实施例提供一种按键，使用该按键的开关组件，通过厚壁区域实现按键的固定，通过薄壁区域产生形变量，从而能够在外力作用下实现对开关部件的有效触发，且自带恢复力，可以实现自恢复；通过薄壁区域与厚壁区域一体成型设计，可以在结构简单的同时，起到非常好的防水防尘效果。通过厚壁区域的设置，使得该按键可以方便的与其他结构相互固定。下面通过具体的实施例进行详细描述。
实施例一
本发明实施例一提供一种按键，包括薄壁区域和厚壁区域；其中，薄壁区域的厚度小于2mm，薄壁区域的面积与厚度的比值大于1177.5mm，在外力的作用下能够产生形变量；厚壁区域用于固定按键。
上述按键，薄壁区域具备弹性，在不需要额外复位支撑机构的情况下，可以在外力撤去的情况下，自动复位。薄壁区域还具备刚性，可直接触发开关部件。按键的薄壁区域具备触发开关部件的刚性，同时自带按键回复力，可以自回复，同时该薄壁按键还带有厚壁区域，可以简单的与其他结构相融合，相比硅胶按键无法做到既能自我支撑，自动复位，又具备很好的刚性触发功能，同时硅胶按键与其他结构的融合也比较复杂。
对于具有薄壁的按键，一方面希望薄壁的面积大，能够在较大范围内实现按压触发开关结构，另一方面，薄壁面积太大并且厚度太薄的情况下不容易成型，会降低产品良率。发明人经试验认为薄壁区域的厚度在0.2～1mm之间能够满足产生有效的变形触发开关部件的要求，优选的可以是0.5～0.7mm。薄壁区域包括与开关部件位置对应的按键动作区域，通常使得薄壁区域在1500g的外力作用下，按键动作区域产生的形变量不小于0.69mm。
为了便于加工成型，简化按键结构，使薄壁部分与按键其它部分采用相同的材料能有效降低成本，因此优选的薄壁区域和厚壁区域一体成型，按键材料为塑料(以树脂为主要材料，增加一些改性的辅助材料，比如增加颜色、防火、抗UV等添加剂)或树脂(PC、ABS、PC+ABS等素材原料)。
可选的，按键可以设计为不同的形状，具体应用中，按键为圆形或方形，按键的外侧部分为厚壁区域，中间部分为薄壁区域，薄壁区域的中心位置设置按键抵接臂，用于抵接开关部件。
可选的，按键的薄壁区域可以设置一个或多个，设置多个时，按键包括由 厚壁区域分隔开的多个薄壁区域，薄壁区域之间通过厚壁做间隔。优选的，相邻的薄壁区域之间的间隔区域的厚度大于间隔距离。对于多个薄壁区域，薄壁区域之间的间隔部分厚度大于薄壁区域之间的间隔，有利于减少薄壁区域之间的互相干扰。
如图1所示的一种圆形的按键，包括薄壁区域111和厚壁区域112；薄壁区域111位于厚壁区域112内，薄壁区域与厚壁区域之间，存在逐渐过渡的缓冲区域，该区域为了使薄壁和厚壁一体成型缺陷更少，薄壁区域可以为圆形或椭圆形，薄壁区域111中部设有抵接臂13，为一体成型方便，不会产生明显的成型缺陷，抵接臂包含中部凸起，以及从中部向四周逐渐变薄的过渡区域。如图2和图3所示的一种方形的按键，包括多个薄壁区域111a，薄壁区域111a被厚壁区域112a分隔开，每个薄壁区域111a中部均设有抵接臂13a。图3中示出了薄壁区域111a的剖面。
可选的，上述按键可以设计平板按键，也可以设计为带有侧壁的按键，带有侧壁的按键包括按键面板和按键侧壁，按键面板包含薄壁区域和厚壁区域，薄壁区域为圆形，按键抵接臂的厚度大于薄壁区域的厚度，在按压包括抵接臂区域在内的薄壁区域时，触发开关部件，按键侧壁为厚壁区域。
如图1所示的圆形按键，可以设计为平板按键也可以设计为包括按键侧壁，图1中是以包括按键侧壁为例的，即该按键包括按键面板11和按键侧壁12，按键面板11包含薄壁区域111和厚壁区域112，按键侧壁12和厚壁区域112一起也可以称为厚壁区域，只要能与薄壁区域区分，起到固定按键和支撑薄壁区域的作用即可，薄壁区域111为圆形，按键抵接臂13的厚度大于薄壁区域111的厚度，在按压包括抵接臂区域在内的薄壁区域时，触发开关部件，按键侧壁12为厚壁区域，按键低接臂与按键为一体注塑成型。
如图2所示的方形按键可以设计为平板按键也可以设计为包括按键侧壁，图2中所示的，即该按键包括按键面板11a和按键侧壁12a，按键面板11a包含厚壁区域112a和多个薄壁区域111a，薄壁区域111a为长方形，多个薄壁区域111a可以形状相同也可以不同，多个薄壁区域111a被厚壁区域112a分隔开，按键抵接臂13a的厚度大于薄壁区域111a的厚度，在按压包括抵接臂区域在内的薄壁区域时，触发开关部件，按键侧壁12a为厚壁区域。如图2所示的可以是一种86形开关，设置六个薄壁区域和六个抵接臂。薄壁区域之间的隔离区域中还设有支撑筋19a，对隔离区域进行加强，进一步避免各薄壁区域之间的互相干扰，防止按压某薄壁区域时，误触发其他薄壁区域对应的开关部件。
本发明实施例提供的按键包括薄壁区域和厚壁区域，通过厚壁区域实现按键的固定，并且支撑薄壁区域，通过薄壁区域产生形变量，从而能够在外力作用下实现对开关部件的有效触发，且自带恢复力，可以实现自恢复；且薄壁区域本身或者设置低接臂就可以触发开关部件，相比硅胶材料具备很好的刚性。通过设置厚壁区域，使得薄壁区域有支撑点，可以通过厚壁区域与其他部件方便的连接，通过薄壁区域与厚壁区域一体成型，节约了生产工序和成本，并且薄壁区域和厚壁区域连接部分密封良好，为后续设计防水防尘产品提供了基 础。
对本发明实施例一所提供的按键，在施加外力时的位移变化的仿真模拟效果如图4和图5所示，其中，图4为在薄壁区域中心区域施加外力时的位移变化示意图，图5为在薄壁区域偏离中心的区域施加外力时的位移变化示意图。
可见从力的作用点位置位移变化最大，然后向四周位移逐渐减小，厚度和薄壁区域面积的改变，均会对位移变化产生影响，薄壁区域面积越大，位移变化就越大，相同薄壁区域面积，厚度越小，位移就越大。实践中可以通过改变这两个参数来改变薄壁区域的按压面积，例如希望薄壁区域按压面积大，则薄壁区域厚度就可以选择厚一些，希望薄壁区域按压面积小，则薄壁区域可以选择薄一些，通过仿真计算和实际测试不同的面积与厚度的关系，如图6所示的曲线，表示位移和圆形薄壁区域直径的关系曲线，在相同的力(1500g)，相同的薄壁厚度(0.6mm)的情况下，可以得出薄壁区域面积和厚度的比值需要大于1177.5mm，才能保证位移大于0.69mm，因为一般轻触按键需要位移大约0.3mm—0.5mm才能触发，因此在此基础上，薄壁按键需要设计出位移大于轻触按键位移，确保薄壁按键可以触发轻触按键，否则薄壁按键的体验会变差，甚至不能起到薄壁按键应有作用。特别是薄壁按键的按压一般我们不会限定在仅按压在中间，而是在一定区域内都可以按压，但开关部件的检测点是固定的，我们可以把开关部件设置在中间，此时如果按压非中间部位，如图4和图5所示，就需要薄壁的面积和厚度的比值更大一些，才能满足按压非中间部位的需求。本设计预留了合适的薄壁按键形变余量，可以确保薄壁按键的手感较好，并且能满足频繁按压薄壁按键的条件，可应用于经常触发按键的使用环境下，经测试薄壁按键的按压寿命可以达到20万次以上。
实施例二
本发明实施例二提供一种开关组件，如图7、图8所示，包括开关部件5和按键1。其中按键1可以实施例一中提供的按键，开关部件5可以实施为轻触开关
开关部件5安装在控制板3上；
按键1的厚壁区域与控制板3固定连接，其薄壁区域与开关部件5位置对应，在外力作用下能够抵接开关部件5，在外力撤除时，可以复位。
可选的，按键的厚壁区域中可以设置一个或多个固定柱，用于固定控制板。控制板上具有有固定柱对应的固定孔，厚壁区域的固定柱穿过控制板的固定孔，通过热熔的方式固定在厚壁区域。按键厚壁区域上的固定柱为窄条形状。可选的，按键厚壁上的固定柱大于1个，且至少有一个的形状与其它固定柱不同。本实施例有4个固定柱，其中一个固定柱171小于其他3个固定柱172、173、174，控制板上的固定孔同样是存在一个固定孔311与固定柱171相适应，另外三个固定孔312、313、314与固定柱172、173、174相适应。这样可以在安装控制板时，只能沿一个方向装配，确保装配方向的正确。
如图7为一种开关组件的结构示意图，以圆形按键、方形控制板为例，实际应用中按键和控制板的形状可以根据需要进行设计。图7所示的开关组件包 括按键1和开关部件5，开关部件5安装在控制板3上，通过按键1的厚壁区域将按键1与控制板3固定在一起。
开关部件定位在控制板(PCB板)上，该PCB电路板与按键的厚壁区域固定连接，以此来保证开关部件和按键的装配误差仅由按键和PCB板决定，整个按键其他零部件的尺寸不影响开关部件和按键的定位精度。因按键具有薄壁设计，形变量比较小，因此该设计保证了开关部件与按键的装配尺寸精度。
实施例三
本发明实施例三提供一种信号发射器，其结构如图9所示，包括按键1、底壳2、控制板3和密封件4。
密封件4与按键1和底壳2配合，形成密封腔；
控制板3位于密封腔内，控制板3连接有开关部件5；
按键1受到外力时抵压并触发开关部件5。
控制板3可以是PCB板，具备无线信号收发功能，布置有无线收发电路以及其天线和其他电路，连接有开关部件，当然天线也可以不布置在电路板上，而采用导线或者螺旋天线，如果布置在电路板上，对电路板的体积就有一定的要求，实际应用中，如果发射信号为2.4GHz的高频信号，因天线尺寸需求比较小，所以可以尽量缩小电路板的体积，例如布置成方形，这样的方形电路板在制造过程中可以节约PCB板材，如果信号为433MHz等载波频率略低的高频信号，则对天线的尺寸要求较高，为了缩小按键的整体尺寸，可以将PCB板做成圆形，来适应整个按键的面积，这样做PCB板的面积最大，可以在周围布置天线。
本实施例提供一种具有防水功能的信号发射器，该信号发射器中的按键1为实施一提供的按键，即按键1为一种薄壁按键，通过薄壁按键实现轻触即可触发开关部件的功能，开关部件也可以是一种轻触开关。即通过增加密封件，比如防水胶条、胶圈等，使按键的固定部和信号发射器底壳之间形成密封，实现防水无需额外的防水设计，结构简单可靠。该信号发射器整体结构简单，操作方便，拆装容易，便于用户更换或维修内部零部件，卡合紧密，不易松动，且防水性能良好。通过薄壁按键的设计以及防水密封圈，实现了简单可靠的防水防尘功能。
该信号发射器的按键1是以圆形按键为例进行说明的，实际应用中按键的形状可以根据需要设计，按键1和底壳2可以组装和拆卸，密封件4与按键1和底壳2配合可以实现密封，控制板3安装在密封腔内可以在按键1或底壳2上设置一个或多个固定柱，可以通过热熔的方式将控制板3与固定柱固定在一起，当然也可以是用螺钉、卡钩或其他方式来固定。通过按压按键的薄壁区域可以触发开关部件，开关部件可以是轻触开关或其他检测开关。
上述信号发射器中，密封件4与按键1和底壳2配合形成密封腔，以便实现有效的防水密封。可以通过按键1和底壳2组装后挤压密封圈，形成防水密封。防水密封可以有不同的设计形式，不同的配合方式，只要最终能能够通过密封件与按键和底壳的配合形成密封，保证能够起到防水作用即可。
参见图10所示的信号发射器的剖面图，防水密封的一种可选的设计方式可以是：信号发射器的底壳2包括底壳侧壁21和底板22；按键1包括按键侧壁12和面板11；面板11内侧设有第一凸起部113，第一凸起部113和按键侧壁12形成第一密封件安装槽114；密封件4安放在第一密封件安装槽114内，按键1和底壳2卡合时，底壳侧壁21压紧密封件4，形成密封腔。这种方式将密封件4安放在按键1上，通过底壳2压紧密封件4，实现防水密封。
防水密封的另一种可选的设计方式可以是：底壳2包括底壳侧壁21和底板22；按键1包括按键侧壁12和面板11；底板22内侧设有第二凸起部，第二凸起部和底壳2侧壁形成第二密封件安装槽；密封件4安放在第二密封件安装槽内，按键1和底壳2卡合时，按键侧壁12压紧密封件4，形成密封腔。第二凸起部和第一凸起部类似，只是设置在底壳2上。这种方式将密封件4安放在底壳2上，通过按键1压紧密封件4，实现防水密封。
密封件可以卡装在按键上也可以卡装在底壳上，第一凸起部113或第二凸起部也可以有不同的形状，比如第一凸起部或第二凸起部为环形肋板、至少两段弧形肋板或多个柱状凸起。即用于固定密封圈的凸起结构可以是圈形凸起，也可以是四角凸起。参照图8所示的，第一凸起部是不连续的多个肋板或凸起，如图8所示的181、182、183，图8所示，每个肋板凸起对应一个定位柱，每个肋板中间有间隔，其中有一个肋板凸起未画出。
上述信号发射器中，按键1和底壳2可以有不同卡合方式来保证两者能够紧密卡合。
第一种可选的卡合方式是底壳2和按键1通过扣合卡扣扣合，底壳2和按键1中的一个设置扣合公扣，另一个设置扣合母扣；扣合公扣为装配卡钩，扣合母扣为与卡钩形状适配的装配卡槽；按键1和底壳2扣合后，装配卡钩嵌入装配卡槽，装配卡钩的水平限位面和装配卡槽的水平限位面配合防止按键和底壳分离，装配卡钩的左右侧面和装配卡槽的左右侧面配合防止按键和底壳旋转。这种方式，通过扣合卡扣来实现底壳2和按键1的组装，能够有效地防止底壳2和按键1的上下和左右松动，拆解时将底壳2和按键1沿上下方向拆开，使装配卡钩从装配卡槽脱出。
第二种可选的卡合方式是：底壳2和按键1通过防脱松卡扣扣合；底壳2和按键1中的一个设置防脱松公扣，另一个设置防脱松母扣；防脱松公扣为设置在凹槽中的固定卡钩，防脱松母扣为位于卡钩孔中的弹性卡钩，弹性卡钩的弹片端固定于卡钩孔的侧壁上、卡钩端为自由端；按键2和底壳1扣合后，弹性卡钩的卡钩端嵌入凹槽中、与固定卡钩卡合，固定卡钩的竖直限位面和弹性卡钩的竖直限位面配合防止按键1和底壳2旋转，弹性卡钩的上下侧面和装配凹槽的上下侧面配合防止按键1和底壳2分离。这种方式，通过防脱松卡扣来实现底壳2和按键1的组装，能够有效地防止底壳2和按键1的上下和左右松动，拆解时将底壳2和按键1沿转动方向相对旋转一个小角度，使弹性卡钩和固定卡钩脱离。
第三种可选的卡合方式是：底壳2和按键1通过扣合卡扣和防脱松卡扣扣 合；底壳2和按键1中的一个设置扣合公扣，另一个设置扣合母扣；以及底壳2和按键1中的一个设置防脱松公扣，另一个设置防脱松母扣；扣合公扣为装配卡钩，扣合母扣为与卡钩形状适配的装配卡槽；防脱松公扣为设置在凹槽中的固定卡钩，防脱松母扣为位于卡钩孔中的弹性卡钩，弹性卡钩的弹片端固定于卡钩孔的侧壁上、卡钩端为自由端；按键2和底壳1扣合后，装配卡钩嵌入装配卡槽，装配卡钩的水平限位面和装配卡槽的水平限位面配合防止按键和底壳分离；弹性卡钩的卡钩端嵌入凹槽中、与固定卡钩卡合，固定卡钩的竖直限位面和弹性卡钩的竖直限位面配合防止按键和底壳旋转。这种方式，通过扣合卡扣和防脱松卡扣实现底壳2和按键1的组装，扣合卡扣可以限制上下松动，防脱松卡扣可以限制左右松动，从而有效地防止底壳2和按键1的上下和左右松动，拆解时将底壳2和按键1沿转动方向相对旋转一个小角度，使弹性卡钩和固定卡钩脱离，旋转一个小角度后，装配卡钩和装配卡槽也会脱离。弹性卡钩和固定卡钩组成的防脱松卡钩可以使底壳2和按键1组装时轻松转动即可卡入，拆解时需要稍用力才能转动脱离。
如图11、图12和图13所示，以同时设置扣合卡扣和防脱松卡扣为例，底壳2上设置装配卡钩23作为扣合公扣，按键1上设置与卡钩形状适配的装配卡槽14作为扣合母扣，同时，底壳上设置位于卡钩孔中的弹性卡钩24作为防脱松母扣，按键1上设置位于凹槽中的固定卡钩15作为防脱松公扣。其中防脱松卡扣以对称设置两个为例，扣合卡扣以圆周均匀设置四个为例。
如图14为按键1上设置的位于凹槽中的固定卡钩15的放大图，该固定卡钩15位于按键1侧壁上的凹槽16中。如图15为底壳21上设置的位于卡钩孔中的弹性卡钩24的放大图，弹性卡钩24的弹片端241固定于卡钩孔25的侧壁上、卡钩端242为自由端。如图16所示为弹性卡钩和固定卡钩卡合后的结构放大图，按键2和底壳1扣合后，装配卡钩23嵌入装配卡槽14，装配卡钩23的水平限位面和装配卡槽14的水平限位面配合防止按键1和底壳2分离；弹性卡钩24的卡钩端242嵌入凹槽中、与固定卡钩15卡合，固定卡钩15的竖直限位面和弹性卡钩24的竖直限位面配合防止按键1和底壳2旋转。装配卡槽14的临近按键侧壁边缘的一侧装配后会承受力，因此在该侧做加厚处理，装配卡槽的受力侧厚度大于非受力侧厚度，所加厚度适应底壳和按键装配的间隙，在间隙范围允许内，尽量增加装配卡槽边沿的厚度，以使装配卡槽稳定的与卡扣配合。卡槽14的进入卡槽的部位，程一定的斜度，确保卡扣能顺利的进入。
如图17所示的，弹性卡钩设置在底壳的底壳侧壁上或按键的按键侧壁上时，底壳侧壁或按键侧壁设置弹性卡钩的位置为双层侧壁，双层侧壁之间为弧形孔，其中一层侧壁上开有卡钩孔，用于容纳弹性卡钩。通过双层侧壁结构的设计，虽然外壁上开设了卡钩孔，由于内壁的存在还是可以起到很好的防水效果，保证密封防水性能，也就是说通过双层侧壁的设计，使内壁与防水密封件和按键形成防水腔，而卡扣等活动机构设置在不影响防水效果的外臂。
可选的，上述信号发射器还包括发光部件61和聚光部件62。如图9和18 所示的，发光部件连接在控制板3上，聚光部件62环绕所述发光部件61。发光部件61和聚光部件62在实际应用中可以有不同的设计形式，一般使发光部件61对应的发光区域位于薄壁区域范围内，以便更有利于光线的透出，为进一步提高透光效果，可以进一步使薄壁区域变薄来形成发光区域。
发光部件61可以是LED，聚光部件62可以使环形泡棉。环形泡棉贴附于PCB上，将LED围住，可起聚光作用。按压按键中间区域时可触发检测开关，此时发射器会发出信号，同时LED会亮灯，LED发出的光通过环形泡棉的聚光作用，直接透过按键的薄壁来透光，不需要额外的导光柱，同时也能达到比较好的防水效果。
发光部件61和聚光部件62的一种设置方式是：发光部件61设置在控制板3上，聚光部件62围绕发光部件61，且位于按键1的薄壁区域覆盖范围内。
其中，聚光部件62为柔性部件，可以随着薄壁区域的形变而形变。
发光部件61所对应的发光区域对应的薄壁区域的厚度小于薄壁区域其他部分的厚度，以利于光线透射出来。
发光部件61和聚光部件62另一种可选的设置方式是：发光部件61设置在控制板3上，聚光部件62围绕发光部件，且位于按键的厚壁区域覆盖范围内，并且厚壁区域对应的发光区域需要减薄，以达到良好的透光效果，并且具有防水防尘的效果。
上述信号发射器其控制板3可以安装在按键1上，也可以安装在底壳2上，还设置有用于安装电池的结构。例如可以在按键或底壳内侧设置有用于安装控制板的固定部，控制板上面设置开关部件5，下面设置电池安装座71。电池安装座中可以装入电池72。
如图18所示的，电池安装座71位于控制板3的下方，开关部件位于控制板3的上方，电池在开关部件5的另一面，可以保证开关部件5和电池72都居中，有助于缩小产品尺寸，给电池预留足够的空间，增加电池选用的灵活度，可以保持产品的重心居中，提升产品的体验感。需要更换电池时，稍用力转动按键1，让扣合卡扣和/或防松脱卡扣脱离即可取下按键1，若控制板3安装在按键上，则控制板3同时被取下，若控制板3安装在底壳2上，则拆下控制板3，此时便可更换电池，更换完成后组装还原。
电池安装座71可以设计为使电池垂直装入或者侧面装入均可。
如图18和19所示的，电池垂直装入的一种可选结构可以是，电池安装座71包括安装在控制板3下面的多个弹性片711，多个弹性片711形成允许电池从垂直于控制板底面的方向装入的环形电池容纳槽，多个弹性片711配合卡紧装入电池容纳槽的电池72，使电池72的正负极分别与控制板上的正负极接触。电池72垂直卡入在电池安装座内，方便电池更换。
如图20、21、22和23所示的，电池侧面装入的一种可选结构可以是，电池安装座71包括固定在控制板下面的电池托盘712，电池托盘712至少一侧面开设有电池出入口，电池装入导电电池托盘后，其正负极中的一极接触导电托 盘，另一极接触控制板上的电极31。电池从侧面装入或取出，电池负极直接采用PCB焊盘，不需要焊额外的电池负极，可节省成本。控制板可以采用方形或圆形等不同的形状可根据实际情况，尤其是无线信号发射天线的布局，来选用板形。如图20和21为圆形控制板的示例图，图22为方形控制板的示例图。其中图20所示的控制板固定在按键1上为例，按键1上有四个固定柱17，其中一个固定柱比其他固定柱小。
如图24、图25、图26为控制板3上设置带电池托盘712的电池座的一个示例图，其中图24为图25的右视图，显示控制板上面的结构，图26为图25的左视图显示控制板下面的结构。可选的，控制板3上通过PCB的铜箔绘制成接触电池的电极31。电极可以采用网格的形式绘制。电极表面采用镀锡或者沉浸工艺。此外，控制板3上发光部件61为中心的一定区域范围内可以涂上反光层63，更有利于光线从按键薄壁区域透出，该反光层可以为PCB电路板工艺中的白色丝印，制作PCB电路板时可以直接制作出来，无需增加成本。
控制板3上通过PCB的铜箔绘制成的电极3形状可以根据需要设计，例如可以是圆形，且电极面积大于电池上用于接触该电极的电极端的表面面积，可以确保电池的电极与PCB电极良好的接触。可选的，控制板上的电极在圆形的基础上，还包括一侧方形结构，该方形结构位于电池出入侧，可以保证电池在出入时，在电池直径范围内均为电极，而无其他可能存在的PCB走线。如图26所示的电极31上半部分是圆形，下半部分是方形，可以是长方形也可以是正方形。
电池安装座下面还可以设置用于辅助支撑电池安装座的支撑件73，支撑件73安装在底壳2的底板22内侧或电池安装座71的下方。该支撑件可以是环形支撑件，具体可以选用环形泡棉，贴附在底壳2上可辅助电池固定防止脱落，也可以辅助支撑控制板。
如图27所示的，底壳2上还可以设置多个支撑筋223，支撑筋223用于辅助支撑控制板以及对电池进行限位。图27中以4个支撑筋为例，一方面可辅助支撑控制板3；另一方面针对侧向式电池安装座，该支撑筋可对电池进行限位，避免电池滑出有效接触区外。
上述信号发射器中还包括可吸附在电池安装座或电池上的永磁体74，永磁体74位于支撑件73环绕区域内。采用侧面安装电池设计方式时，可以更方便使用永磁体，即将永磁体直接吸附在电池安装座或电池上，这样信号发射器在使用时可直接吸附在铁质或磁性材料的表面，而不需借助双面胶、螺丝等额外方式来固定。同时上述的支撑件可以使用带胶环形泡棉，其贴附于电池安装座或底壳上，一方面可支撑电池安装座，避免电池安装座焊盘脱落，另一方面可圈住永磁体，避免永磁体随意滑动。

如图29所示的，实际应用中，该信号发射器底部还可以设置防滑垫8，来避免发射器放置在桌面等表面后，按压出现滑动，背面也可以采用双面胶9的固定形式，以便于该发射器粘贴到其他物体表面，还可以采用永磁体内置的方式，来使该发射器可以吸附在磁性物体表面。当然，以上几种发射器固定安装方式也可以组合在一起使用，例如既内置永磁体74，又设置了环形的防滑垫8，还设置有圆形的双面胶9，也可以选择其中的两种安装方式组合，或者将环形的防滑垫8变为双面胶，圆形的双面胶9变为防滑垫，防滑垫和双面胶留出的空白部分可以粘贴产品信息标签，或则镭雕产品信息，也可以底壳背面整面的设置双面胶或者防滑贴，然后在双面胶或者防滑贴上镭雕产品信息，或者粘贴产品信息标签，也可以将产品信息标签粘贴到产品的侧面，或者镭雕到产品的侧面。
信号接收器设置于电子设备中，用于接收信号发射器发送的控制信号，基于控制信号控制电子设备执行相应操作。
电子设备为电子门铃、报警器、扫地机器人、电动窗帘、马桶、照明装置、热水器或浴霸。
前述信号发射器能广泛应用于电子装置中，电子装置通过信号接收器接收信号发射器发送的控制信号，根据收到的控制信号就能执行设定操作。例如，在一些实施方式中，电子装置为门铃或者报警器，其根据收到的控制信号发出相应的提示音。在一些实施方式中，电子装置为马桶，其根据收到的控制信号执行设定的冲水或其他操作。此外，电子装置还可以为扫地机器人、电动窗帘、照明装置、热水器或浴霸灯。也就是说，本发明的信号发射器结构简单、小巧轻便，适用于多种无线控制场景，且由于具备优异的防水性能，尤其适用于马桶、热水器或浴霸等处于潮湿工作环境的电子装置。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。
以上所述，仅为本发明的具体实施例，不能以其限定发明实施的范围，所以其同等组件的置换，或依本发明专利保护范围所作的等同变化与修饰，都应仍属于本专利涵盖的范畴。尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
在上述的详细描述中，各种特征一起组合在单个的实施方案中，以简化本公开。不应该将这种公开方法解释为反映了这样的意图，即，所要求保护的主题的实施方案需要清楚地在每个权利要求中陈述的特征更多的特征。相反，如所附的权利要求书所反映的那样，本发明处于比所公开的单个实施方案的全部特征少的状态。因此，所附的权利要求书特此清楚地被并入详细描述中，其中每项权利要求独自作为本发明单独的优选实施方案。
上文的描述包括一个或多个实施例的举例。当然，为了描述上述实施例而描述部件或方法的所有可能的结合是不可能的，但是本领域普通技术人员应该认识到，各个实施例可以做进一步的组合和排列。因此，本文中描述的实施例旨在涵盖落入所附权利要求书的保护范围内的所有这样的改变、修改和变型。此外，就说明书或权利要求书中使用的术语“包含”，该词的涵盖方式类似于术语“包括”，就如同“包括，”在权利要求中用作衔接词所解释的那样。此外，使用在权利要求书的说明书中的任何一个术语“或者”是要表示“非排它性的或者”。
