结合图3、图4和图5，在本申请实施方式中，壳组件10包括第一壳体12和第二壳体14，第二壳体14和第一壳体12能够相对运动。具体地，在本实施方式中，第二壳体14和第一壳体12滑动连接。换言之，第一壳体12能够相对第二壳体14滑动。例如，第一壳体12和第二壳体中14的一者可以设有滑轨，另一者可沿滑轨滑动。
第一壳体12能够相对第二壳体14滑动至第一位置和第二位置。结合图4，第一壳体12在第一位置时，电子设备100可以获得相对较大的显示面积，以提升电子设备100的使用体验；第一壳体12在第二位置时(可参考图1)，电子设备100具有相对较小的外形尺寸，便于携带。
在本实施方式中，第一壳体12在第一位置时，电子设备100的整机宽度大于在第二位置的宽度，以使暴露的柔性屏模组20的宽度尺寸可变。换言之，电子设备100在宽度方向的尺寸可变。在这种实施方式中，电子设备100的外部接口例如数据线插孔或者充电线插孔或者耳机插孔可以设置于宽度方向的端部。在其他实施方式中，第一壳体12在第一位置时，电子设备100的整机长度大于在第二位置的长度，以使暴露的柔性屏模组20的长度尺寸可变。换言之，电子设备100在长度方向的尺寸可变。在这种实施方式中，电子设备100的外部接口例如数据线插孔或者充电线插孔或者耳机插孔可以设置于长度方向的端部。
具体地，请参阅图6和图7，第一壳体12与第二壳体14可以共同形成收容空间16。可以理解的是，收容空间16可以随着第一壳体12与第二壳体14的相对移动而发生变化。收容空间16可用于放置引导件30、电路板、电池及电声器件40等。柔性屏模组20可以包括相对设置的固定端20a和自由端20b，固定端20a设置于第一壳体12，在第二位置时柔性屏模组20绕过引导件30，且柔性屏模组20的自由端20b容纳于壳组件10内，以使部分柔性屏模组20隐藏于壳组件10，隐藏于壳组件10内的部分柔性屏模组20可不用于显示。
可以理解的是，固定端20a和自由端20b可以按照以下方式进行区分，第一壳体12相对第二壳体14处于第二位置时，外露于壳组件10的那部分柔性屏模组20即为柔性屏模组20的固定端20a，收容于壳组件10内的那部分柔性屏模组20即可视为自由端20b。
进一步，第二壳体14可以包括后盖142，在第二位置时后盖142覆盖柔性屏模组20的自由端20b。后盖142可以设置透光区域，在第二位置时收容于壳组件10的那部分柔性屏模组20也可以用于显示，以使用户能够从透光区域查看柔性屏模组20显示的信息，进而拓展电子设备100的使用场景。例如，在这种实施方式中，电子设备100无需设置前置摄像头，采用后置式的摄像头模组50即可实现自拍、视频通话等功能。透光区域可以由透明玻璃构成，亦可以是后盖142的开孔形成。第一壳体12相对第二壳体14滑动至第一位置后，收容于壳组件10的至少部分柔性屏模组20暴露。暴露的柔性屏模组20可用于显示，以使得电子设备100具有相对较大的显示面积，以提升用户的使用体验。
在本实施方式中，引导件30设置于第二壳体14的远离第一壳体12的一端，在第一壳体12相对第二壳体14从第二位置切换至第一位置的过程中，引导件30可以引导柔性屏模组20变形并展开于第二壳体14。引导件30可以将柔性屏模组20的弯曲半径限制在适宜的范围内，以避免弯曲半径过小造成柔性屏模组20的损伤。当然，引导件30也可以 避免柔性屏模组20弯曲半径过大造成电子设备100厚度过大。如图7所示，在一些实施方式中，引导件30可为带有齿的转轴结构，柔性屏模组20通过啮合等方式与引导件30相联动。第一壳体12和相对第二壳体14滑动时，通过引导件30带动啮合于引导件30上的部分柔性屏模组20移动并展开或收回壳组件10内。
可以理解的是，在其他实施方式中，引导件30还可为不附带齿的圆轴。在第一壳体12由第二位置切换至第一位置的过程中，通过引导件30将贴合于引导件30上的部分柔性屏模组20撑开，以使更多的柔性屏模组20暴露于壳组件10外侧，并处于平展状态。
在这种实施方式中，引导件30可转动地设置于第二壳体14，在逐步展开柔性屏模组20的过程中，引导件30可随柔性屏模组20的移动而转动，以减小柔性屏模组20在展开过程中所受到的阻力，并减小引导件30的磨损。
在另一些实施例中，引导件30也可固定在第二壳体14上，引导件30具有光滑的表面。在将柔性屏模组20展开的过程中，引导件30通过其光滑的表面与柔性屏模组20可滑动接触。换言之，在这种实施方式中，引导件30可以和第二壳体14一体成型或者焊接成型，引导件30可以视为第二壳体14的一部分，柔性屏模组20的自由端20b绕过第二壳体14的远离第一壳体12的一端并伸入壳组件10内。
在第一壳体12由第一位置切换至第二位置的过程中，柔性屏模组20可通过引导件30带动收回，即使得展开于第二壳体14的那部分柔性屏模组20收回壳组件10内。进一步，在一些实施方式中，电子设备100可以包括驱动机构60，驱动机构60可设置在壳组件10内，驱动机构60可与第二壳体14或者第一壳体12相联动，以驱动第一壳体12相对第二壳体14移动，进而带动柔性屏模组20展开或收回。可以理解的是，驱动机构60可以省略，用户可以直接通过手动等方式来使得第一壳体12和第二壳体14相对移动。
参阅图8和图9，电子设备100可以包括张紧组件70，柔性屏模组20的自由端20b与张紧组件70联动，在第二壳体14由第一位置切换至第二位置的过程中，张紧组件70带动柔性屏模组20复位，进而使得部分柔性屏模组20收回于壳组件10内。在柔性屏模组20收回于壳组件10内后，电子设备100可以获得相对较小的外形尺寸，以提升电子设备100的便携性。
在一些实施方式中，张紧组件70设于壳组件10内并与柔性屏模组20的自由端20b连接。张紧组件70包括弹性件和活动件71，活动件71转动连接于第二壳体14。弹性件可以为扭簧，扭簧的一个自由端20b连接于第二壳体14，扭簧的另一自由端20b连接于活动件71，且扭簧套设于活动件71。第一壳体12相对第二壳体14在第一位置和第二位置之间切换的过程中，扭簧产生扭转变形并通过活动件71对柔性屏模组20施加张紧力。
在柔性屏模组20伸出壳组件10的过程中，即第一壳体12从第二位置切换至第一位置的过程中，柔性屏模组20的自由端20b带动活动件71相对第二壳体14转动，以释放卷绕于活动件71的柔性屏模组20，弹性件积蓄弹性势能，活动件71对柔性屏模组20施加的张紧力为阻力，以使柔性屏模组20能够平整地展开于第二壳体14；在柔性屏模组20收回壳组件10的过程中，即第一壳体12从第一位置切换至第二位置的过程中，弹性件释放弹性势能并驱使活动件71复位，活动件71对柔性屏模组20施加张紧力为动力，以使柔性屏模组20能够平稳地收回壳组件10，以使自由端20b卷绕于活动件71。
在其他实施方式中，张紧组件70可以具有其他结构形式，例如，活动件71、弹性件 可以省略，张紧组件70包括弹性绳，弹性绳连接于第二壳体14或者第一壳体12，以在第二壳体14相对第一壳体12移动过程中利用弹性绳对柔性屏模组20施加张紧力即可。又如，在电子设备100包括驱动机构60的实施方式中，驱动机构60可以和柔性屏模组20的自由端20b连接。在柔性屏模组20伸出壳组件10的过程中，驱动机构60逐渐释放柔性屏模组20并对柔性屏模组20的施加张紧力，以使柔性屏模组20平整地展开于第二壳体14；在柔性屏模组20收回壳组件10的过程中，驱动机构60带动柔性屏模组20的自由端20b逐渐卷绕于轴上，以使柔性屏模组20平稳地收回壳组件10内。在这种实施方式中，驱动机构60可以为电机，也可以为电机与齿轮组的组合。
可以理解的是，在本实施方式中，第一位置、第二位置可以视为第一壳体12相对第二壳体14运动的两个极限位置。在第一位置时，柔性屏模组20的显示面积达到最大状态，在正常情况下，第一壳体12不能再相对第二壳体14继续作相互远离运动。在第二位置时，柔性屏模组20的显示面积达到最小状态，在正常情况下，第二壳体14不能再相对第二壳体14作相互靠近运动。第一位置和第二位置可以通过在第一壳体12或者第二壳体14或者引导件30上设置限位结构来实现，例如，第一壳体12上可以设置弹片，第二壳体14上可以设置两个卡槽，在第一位置时，弹片与其中一个卡槽卡合，从而实现第一壳体12与第二壳体14在第一位置的定位；在第二位置时，弹片与另一个卡槽卡合，从而实现第一壳体12与第二壳体14在第二位置的定位。可以理解的是，在第一位置和第二位置之间还可以设置多个中间位置，以实现第一壳体12相对第二壳体14在多个位置的定位，并使得柔性屏模组20在不同的中间位置具有不同的显示面积，从而拓展电子设备100的使用场景。多个中间位置也可以采用限位结构实现，例如通过弹片与卡槽的配合即可实现第一壳体12相对第二壳体14在多个中间位置的定位。
参考图10和图11，电子设备100的电声器件40可以包括本体41和伸缩件43，本体41可以大致呈矩形块状，且本体41与伸缩件43共同形成音腔41a。伸缩件43的一端连接于本体41，且伸缩件43的一端与第一壳体12、第二壳体14、自由端20b中的一者的位置相对固定，伸缩件43的另一端与第一壳体12、第二壳体14、自由端20b中的余下两者中的一者的位置相对固定。换言之，伸缩件43可以具有第一端43a和第二端43b，本体41可以连接于第一端43a，且第一端43a与第一壳体12、第二壳体14、自由端20b中的一者的位置相对固定，第二端43b与第一壳体12、第二壳体14、自由端20b中的余下两者中的一者的位置相对固定。在柔性屏模组20伸出壳组件10后例如第一位置时，伸缩件43伸长以使音腔41a的容积扩大；在伸出壳组件10的柔性屏模组20收回于壳组件10内后例如第二位置时，音腔41a的容积缩小。
在一些实施方式中，本体41或第一端43a可以与柔性屏模组20的固定端20a或者第一壳体12固定连接，以使本体41和第一端43a的位置与固定端20a的位置相对固定，伸缩件43的第二端43b可以连接于第二壳体14或者柔性屏模组20的自由端20b，以在第一壳体12相对第二壳体14的移动过程中产生伸缩变形。参考图9，在另一些实施方式中，伸缩件43的第二端43b可以与柔性屏模组20的固定端20a或者第一壳体12连接，以使伸缩件43的连接部位与固定端20a的位置相对固定，本体41或者第一端43a则可以和第二壳体14或者柔性屏模组20的自由端20b固定连接，以在第一壳体12相对第二壳体14移动的过程中产生伸缩变形。当然，在其他实施方式中，伸缩件43的第一端43a(或者 本体41)可以连接于第二壳体14、自由端20b中的一者，伸缩件43的第二端43b可以连接于第二壳体14、自由端20b中的另一者，以使伸缩件43在第一壳体12相对第二壳体14移动的过程中产生伸缩变形，以改变音腔41a的容积，进而改变用于反射声音的空间，此处不再赘述。
参考图10，本体41可以包括外壳411和电声模组413，外壳411连接于伸缩件43的第一端43a，电声模组413设于外壳411内并与外壳411及伸缩件43共同形成音腔41a。外壳411开设有用于声音传出的出音孔41b(参考图9)。第一壳体12、第二壳体14和自由端20b中的一者可以与外壳411的位置相对固定，也即第一壳体12、第二壳体14和自由端20b中的一者与电声模组413的位置相对固定。例如，在一些实施方式中，外壳411与固定端20a或者第一壳体12固定连接，以使外壳411与固定端20a的位置相对固定，伸缩件43的第二端43b与第二壳体14或者柔性屏模组20的自由端20b固定连接，以在第一壳体12相对第二壳体14移动的过程中，实现伸缩件43的伸缩变形。又如，在另一些实施方式中，外壳411与第二壳体14或者柔性屏模组20的自由端20b固定连接，以使得外壳411与第二壳体14或者自由端20b的位置相对固定，伸缩件43的第二端43b与第一壳体12或者固定端20a固定连接，在第一壳体12相对第二壳体14移动的过程中，这种方式同样可以实现伸缩件43的伸缩变形。再如，在一些实施方式中，外壳411与自由端20b固定连接，以使得外壳411与自由端20b的位置相对固定，伸缩件43的第二端43b与第二壳体14固定连接，在第一壳体12相对第二壳体14移动的过程中，这种方式同样可以实现伸缩件43的伸缩变形。可以理解的是，本体41的外壳411不是必须的，例如，电声模组413的发声部件可以直接连接至伸缩件43。
进一步，在本实施方式中，在第一壳体12相对第二壳体14移动以使至少部分柔性屏模组20展开于第二壳体14的过程中，也即第一壳体12相对第二壳体14从第二位置切换至第一位置的过程中，伸缩件43伸长并形成通道41a1，伸缩件43的通道41a1作为音腔41a的可变部分，可扩大用于声音的反射、共振的空间，如图10所示。电声模组413可以电性连接于电路板，且电声模组413可用于将电信号转化为声音信号。在其他条件不变的情况下，由于音腔41a的容积可以直接决定电声器件40的低频共振频率，且用于共振的音腔41a的容积越大，低频共振频率越小，也即低频性能越好。因此，在伸缩件43伸长并形成通道41a1后，通道41a1可以增大用于反射电声器件40的声音的空间，因此可以使得电声器件40具有更好的低频效果，也即使得电子设备100具备更好的音质，即提升电声器件40、电子设备100的音效。在第一壳体12相对第二壳体14移动以使展开于第二壳体14的那部分柔性屏模组20收回壳组件10后，也即第一壳体12相对第二壳体14从第一位置切换至第二位置的过程中，伸缩件43的通道41a1的容积减小，用于反射电声器件40的声音的空间减小，因此电声器件40的低频性能相应降低，如图11所示。
相关技术中，智能手机等终端设备的电声器件40的音腔41a的容积一般固定不变，例如，一般的用于终端设备的扬声器的音腔41a的容积在0.6立方厘米～1立方厘米的范围内。在扬声器用于播放音频时，受限于音腔41a的容积，外放的音质无法达到较高的水平。而在本实施方式中，伸缩件43的伸缩变形可以使得用于反射声音的空间发生变化，因此可以根据柔性屏模组20的显示面积适应性地调整电声器件40的外放音质，以拓展电声器件40的使用场景。例如，在电子设备100的显示面积较大(例如玩游戏或者观看电 影等)时，通道41a1增大了音腔41a的容积，因此可以使得电声器件40具有相对较好的低频性能，以提升用户体验，并使得电声器件40的音质与柔性屏模组20显示的画面匹配，即实现音画匹配，使得电声器件40的音量可以增大或者实现更好的声场平衡。在电子设备100的显示面积较小(例如查看信息、浏览网页等)时，伸缩件43的通道41a1的容积减小，通道41a1的容积甚至可以减小至接近0，以降低电声器件40的低频性能，再次实现音画匹配、降低声音的音量、实现声场的平衡。
上述电子设备100，第一壳体12能够相对第二壳体14移动，以带动柔性屏模组20展开于第二壳体14或者收回壳组件10内。在柔性屏模组20展开于第二壳体14时，电子设备100可以获得相对较大的显示面积以提升使用体验，且伸缩件43伸长并形成通道41a1，通道41a1可以扩大声音的反射空间，从而改变电声器件40的音频特性，提升电声器件40的音效；在展开于第二壳体14的柔性屏模组20收回壳组件10后，电子设备100可以获得相对较小的外形尺寸以具备相对较好的便携性，且通道41a1的容积相应减小，因此电声器件40的音频特性也随之改变。上述电子设备100的电声器件40可以根据柔性屏模组20的显示面积的大小调整音频特性，即根据不同的使用场景调整电声器件40的音频特性，从而拓展电声器件40的使用场景。
在上述实施方式中，伸缩件43与外壳411可以密封连接，且伸缩件43的相对的另一端也可以实现密封连接。以外壳411固定连接于第一壳体12为例，伸缩件43的第二端43b可以密封连接于第二壳体14或者自由端20b，伸缩件43可与外壳411、电声模组413共同形成密闭的空间，以获得较好的共振效果，并提升电声器件40的低频性能。
继续参阅图10和图11，在另一些实施方式中，电声器件40还可以包括扩容件45，扩容件45可以大致呈矩形盒状，且扩容件45开设有容腔45a。伸缩件43的第二端43b密封连接于扩容件45。在第一位置时，容腔45a与伸缩件43的通道41a1连通，进而实现容腔45a与音腔41a的连通。扩容件45、外壳411中的一者与第一壳体12、第二壳体14、自由端20b中的一者的位置相对固定，扩容件45、外壳411中的另一者与第一壳体12、第二壳体14、自由端20b中的余下两者中的一者的位置相对固定。
具体地，在这种实施方式中，外壳411可以固定连接于固定端20a或者第一壳体12，以实现本体41与固定端20a的位置的相对固定，扩容件45则可以固定连接于第二壳体14或者自由端20b，以在第一壳体12相对第二壳体14移动的过程中，实现伸缩件43的伸缩变形，并使得伸缩件43所形成的通道41a1的容积发生变化，进而改变电声器件40的低频特性。外壳411也可以固定连接于第二壳体14或者自由端20b，扩容件45固定连接于第一壳体12或者柔性屏模组20的固定端20a，以在第一壳体12相对第二壳体14的移动的过程中，实现伸缩件43的伸缩变形，并使得伸缩件43所形成的通道41a1的容积发生变化，进而改变电声器件40的低频特性。
当然，参考图12和图13，外壳411也可以固定连接于自由端20b，扩容件45固定连接于第二壳体14，以在第一壳体12相对第二壳体14的移动的过程中，实现伸缩件43的伸缩变形，并使得伸缩件43所形成的通道41a1的容积发生变化，进而改变电声器件40的低频特性。在这种实施方式中，由于电声器件40的外壳411、扩容件45及伸缩件43可以均设于第二壳体14内，因此可以提升组装的便利性。
本申请以外壳411、扩容件45中的一者连接于第一壳体12，外壳411、扩容件45中 的另一者连接于第二壳体14为例。这种结构设置，有利于外壳411及扩容件45在壳组件10的装配，例如外壳411或者扩容件45可以采用螺纹连接或者粘接或者焊接等方式固定连接于第一壳体12或者第二壳体14。相比于外壳411或者扩容件45固定连接于自由端20b并能够随自由端20b移动的结构，上述实施方式可以避免伸缩件43发生弯曲变形而降低其疲劳寿命，可以保证电声器件40的使用寿命，并降低组装的难度。
在本申请实施方式中，伸缩件43可以为硅胶件或者橡胶件或者塑胶件，伸缩件43上形成有折横以用于引导伸缩件43的变形。例如，在本实施方式中，在展开于第二壳体14的柔性屏模组20收回于壳组件10后，即第一壳体12处于第二位置时，伸缩件43折叠于外壳411和扩容件45之间，如图11所示。伸缩件43的折叠可以由折横引导实现，以使得伸缩件43的伸缩变形可控，并防止与电子设备100内部的其他元器件产生干涉。在伸缩件43折叠于扩容件45和外壳411之间时，伸缩件43的厚度可以极小，也即通道41a1的容积可以接近于0，从而使得容腔45a与音腔41a形成较好的连通效果，以获得较为稳定的音频特性。当然，可以理解的是，折痕不是必须的。当然，在第二位置时通道41a1的容积可以接近于0的设置不是必须的，也即在第一位置和第二位置及第一位置和第二位置之间，通道41a1可以始终存在，且音腔41a与容腔45a始终连通，容腔45a始终可用于电声模组413的声音的反射、共振。
可以理解的是，扩容件45不是必须的。参考图14，在一些实施方式中，伸缩件43的一端密封连接于第一壳体12，伸缩件43的另一端密封连接于本体41的外壳411，本体41的外壳411连接于第二壳体14。在第一壳体12相对第二壳体14的移动过程中，伸缩件43产生伸缩变形并使得伸缩件43内的通道41a1的容积发生变化，从而使得音腔41a容积产生变化，即可改变电声器件40的音频特性。
进一步，参考图15和图16，在垂直于第一壳体12相对第二壳体14的移动方向上，电声器件40可以间隔设置两个，其中一个电声器件40设置于柔性屏模组20的一端，另一个电声器件40设置于柔性屏模组20的相对的另一端。换言之，在本实施方式中，一个电声器件40设置于电子设备100的长度方向的一端，另一个电声器件40设置于电子设备100的长度方向的另一端。
具体地，两个电声器件40可以区分为第一电声器件410和第二电声器件420，且在本实施方式中，第一电声器件410的扩容件45与第二电声器件420的本体41设于第一壳体12或者与第一壳体12的位置相对固定，第一电声器件410的本体41与第二电声器件420的扩容件45设于第二壳体14或者与第二壳体14的位置相对固定。换言之，第一电声器件410和第二电声器件420可以构成旋转对称图形，例如，在本实施方式中，在第一位置时，第一电声器件410与第二电声器件420关于可以引导件30的中部位置可以呈中心对称。
进一步，第一电声器件410的外壳411开设的出音孔41b设置于外壳411的背向第二电声器件420的一端，第二电声器件420的外壳411开设的出音孔41b设置于外壳411的背向第一电声器件410的一端。在第一壳体12相对第二壳体14运动至第一位置时，电声器件40可以因此获得较好的立体声效果，以提升用户体验。换言之，第一电声器件410的外壳411可从背向第二电声器件420的一端出声，第二电声器件420的外壳411可从背向第一电声器件410的一端出声。当然，结合图16，在第一壳体12相对第二壳体14移 动至第二位置时，上述结构设置也可以使得电声器件40具有相对较好的立体声效果。
进一步，在一些实施方式中，电子设备100可以包括角度传感器(未图示)，角度传感器连接于第二壳体14及引导件30，以用于检测引导件30的旋转角度，角度传感器、电声器件40均与电子设备100的处理器通信连接，处理器用于根据旋转角度控制电声器件40的外放参数。具体地，以第一壳体12相对第二壳体14从第二位置向第一位置移动为例，角度传感器可以采用霍尔传感器或者光电编码器，以用于测量引导件30的旋转角度。根据引导件30的旋转角度即可计算得出柔性屏模组20展开于第二壳体14的长度，进而计算出伸缩件43伸长的长度，进而计算出伸缩件43的通道41a1的容积及音腔41a的容积。根据音腔41a的容积结合容腔45a的容积，可以进一步计算出电声器件40的声音的频率特性，或者可以直接通过实验获得伸缩件43的伸长长度与电声器件40的音频特性的关系，进而适当调整电声模组413的发声特性(例如声音的频率、响度等参数)以实现共振空间与电声模组413的匹配，从而获得较好的外放效果。
在第一位置和第二位置之间设有多个中间位置的实施方式中，可以根据不同的位置设定不同的外放参数，以在不同位置实现不同的外放效果，进而丰富电声器件40的使用场景。更进一步，可以对柔性屏模组20的伸出壳组件10的长度按区间进行划分，并根据长度区间结合音腔41a和容腔45a的容积设定电声器件40的外放参数。在柔性屏模组20的伸出长度处于某一区间时，处理器可以直接将电声器件40的外放参数设定为该区间对应的外放参数。这种配置方式，对于第一位置和第二位置之间无中间位置或者中间位置较少的情况，也即柔性屏模组20的展开面积拥有更大的随机性时，仍然可以实现电声器件40的外放参数与柔性屏模组20的显示面积较好地匹配，实现较好的音画匹配，提升用户的体验。且这种划分区间的控制方式，还可以避免处理器频繁调整电声器件40的发声特性，从而可以保证电声器件40的使用寿命。在其他实施方式中，还可以采用其他传感器例如光电传感器直接或者间接测量柔性屏模组20的展开长度，进而适应性地调整电声器件40的外放参数，此处不再赘述。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
