 本发明的实施方式
下面结合附图和实施方式对本发明作进一步说明。
实施例：
参见图1-图5，一种终端设备，终端设备包括主体部10以及组装于主体部10的发声组件20，发声组件20包括与主体部10可移动连接的壳体21、以及收容于壳体21中的发声单体22，壳体21包括发声面211以及与发声面211相背的背面212，发声面211朝背面212凹陷形成有收容发声单体22的容纳槽2111、以及与容纳槽2111连通的第一发声通道2112，主体部10包括露设的外表面11、与发声面211相对的内表面12、以及自内表面12延伸至外表面11的延伸面13，内表面12与延伸面13形成收容发声组件20的收容槽60；内表面12朝远离发声单体22的方向凹陷形成有延伸至外表面11的第二发声通道121，外表面11对应形成与第二发声通道121连通的第一出声孔1121，终端设备还包括固定于内表面12并覆盖第二发声通道121的盖板30，盖板30贯穿开设有与第二发声通道121连通的第一通孔31；发声组件20在收容槽60内的第一位置和第二位置之间移动；在第一位置时，容纳槽2111与第一通孔31连通，第一发声通道2112由主体部10覆盖，发声组件20产生的声音依次经第一通孔31、第二发声通道1121及第一出声孔121传播至终端设备外侧；壳体21带动发声单体22朝远离第一通孔31的方向移动至第二位置时，至少部分壳体21暴露于终端设备，第一发声通道2112与终端设备外侧连通，发声组件20产生的声音经第一发声通道2112传播至终端设备外侧。
在本发明中，终端设备包括配合组装的主体部10和发声组件20；发声组件20包括壳体21和发声单体22，壳体21与主体部10移动连接，且壳体21的发声面211朝背面212凹陷形成相互连通的容纳槽2111和第一发声通道2112，容纳槽2111用于收容发声单体22；主体部10的内表面12与延伸面13形成收容槽60以收容发声组件20，且内表面12朝远离发声单体22方向凹陷形成第二发声通道121，外表面11开设有第一出声孔1121，第二发声通道121延伸至外表面11并与第一出声孔1121相连通；终端设备还包括覆盖第二发声通道121的盖板30，盖板30上贯穿开设有与第二发声通道121连通的第一通孔31；当发声组件20位于收容槽60中第一位置时，容纳槽2111与第一通孔31连通，主体部10覆盖第一发声通道2112，发声单体22发声，声音经过第一通孔31、第二出声通道121后从第一出声孔1121传出至终端设备的外侧，此时为终端设备的受话器模式；当壳体21相对主体部10直线运动带动发声单体22朝远离第一通孔31的方向移动到第二位置时，使得至少部分壳体21外露于终端设备，发声单体22发出的声音经第一发声通道2112直接向外界传播，此时为终端设备的扬声器模式；运用本技术方案在扬声器和受话器两种模式下提供了两种不同的出音路径，且在扬声器模式下提供了一个更加通畅的出音路径，改善了终端设备在扬声器模式下会产生气流音、钢琴音等进而影响音效的问题。
本技术方案中壳体21可移动的连接在主体部10上，在此对壳体21与主体部10之间的连接方式进行举例说明：在主体部10上固定磁钢，在壳体21上固定与磁钢极性相斥的线圈，磁钢与线圈之间通过弹簧连接，且线圈均与终端设备的电源电连接；当电源与线圈连通时，线圈产生极性并与磁钢相斥拉伸弹簧使壳体21从第一位置移动到第二位置；当电源与线圈断开时，线圈没有极性，弹簧的收缩使壳体21从第二位置移动到第一位置，从未实现壳体21与主体部10的移动式连接，本发明在此不对壳体和主体部之间可移动的连接方式进行限定。
进一步地，图6-图8所示，发声组件20还包括盖设于壳体21的挡板40，挡板40覆盖容纳槽2111及第一发声通道2112，挡板40与发声单体22间隔设置形成前腔50，第一发声通道2112与前腔50连通，挡板40贯穿开设有与前腔50连通的第二通孔41，发声组件20位于第一位置时，第二通孔41与第一通孔31连通。
即通过挡板40盖设在壳体21上以密封覆盖容纳槽2111和第一发声通道2112，且挡板40与发声单体22间隔设置以形成前腔50，防止壳体21与主体部10之间组装不紧密而出现漏音现象；并在挡板40上贯穿开设与前腔50连通的第二通孔41，为受话器模式提供通畅的出音路径。如图10所示，此时壳体21位于收容槽2111的第一位置，图中箭头走向为发声单体22发声后声音的传播路径，第二通孔41与第一通孔31连通，发声单体22发声并依次通过第二通孔41、第一通孔31，和第二发声通道121后从第一出声孔1121传出，实现终端设备的受话器模式。
参见图6、图9及图11，挡板40还开设有与第一发声通道2112连通的第二出声孔42，发声组件20位于第二位置时，至少部分第二出声孔42暴露于主体部10并与终端设备外侧连通，在挡板40相对第一发声通道2112开设第二出声孔42，当壳体21相对主体部10移动到收容槽60的第二位置时，挡板40随着壳体21一起运动从而使得至少部分第二出声孔42露置于外界，发声单体22发声，并经过第一发声通道2112从第二出声孔42向外界大面积传播，从而实现终端设备的扬声器模式。
如图6所示，第二出声孔42呈阵列排布于挡板40，优选地，挡板40远离发声单体22的一侧凹陷有限位槽43，第二出声孔42呈矩阵排列于限位槽43。通过在挡板40远离发声单体22的一侧开设限位槽43，并将第二出声孔42呈矩阵排列开设在限位槽43的槽底上，当终端设备为扬声器模式时，逐步将发声单体22发出的声音限定于第二出声孔42传出，以提高终端设备在扬声器模式下的出音音质，从而提升用户对终端设备的体验效果。
优选地，发声组件20位于第一位置时，第二通孔41与第一通孔31同轴设置且第二通孔41的孔径大于第一通孔31的孔径。即当终端设备为受话器模式时，发声单体22发出的声音由第二通孔42和第一通孔31逐步限定于第二出声通道121进而从第一出声孔1121传出。
参见图4，外表面11包括与内表面12相对的正面111、自正面111边缘朝内表面12方向弯折延伸的侧面112、以及连接在侧面112远离正面111一端的底面113，底面113对应发声组件20朝正面111的方向凹陷形成收容槽60，内表面12延伸至侧面112并与侧面112连接，第一出声孔1121开设于侧面112。且发声组件20位于第一位置时，背面212与底面113拼接且共面，使得终端设备的外部表面平整，提高终端设备的外观审美。
以上的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
