Abstract

The present invention relates to a protective case for being installed on an electronic device. The protective case comprises at least a side frame, wherein the side frame is configured to at least abut against the electronic device at the position where a sound output hole is provided; the side frame is provided with a sound channel which is configured to be in communication with the sound output hole of the electronic device; and the side frame is provided with at least two groups of sound holes, both of which are in communication with the sound channel, with different groups of sound holes being respectively located in different surfaces of the side frame. Sound produced by the electronic device can be output from at least the sound holes in different positions, such that when the electronic device operates, it is generally impossible to block all the sound holes in different positions, and thus, the user experience is not affected. In addition, by means of respectively providing the sound holes in different surfaces, the sound which is originally output in one direction can be dispersed and output in different directions by means of the sound holes in different directions, thereby improving the surround stereophonic effect of the sound.

上述保护壳，用于安装在电子设备上，当电子设备横向使用时，用户的两只手托着电子设备的两端。通过在侧框上设置有至少两组声孔，至少两组声孔分别位于所述侧框的不同表面，这些声孔均通过声音通道与电子设备的出声孔连通。也就是说，电子设备发出的声音至少能够从不位置的声孔输出，用于在操作电子设备时通常不会将不同位置的声孔全部遮挡，因此不会影响用户的使用体验。此外，通过在不同的表面分别设置声孔，可以将原本朝向一个方向输出的声音通过不同方向的声孔分散成朝向不同方向输出，增加了声音的立体环绕效果。The above-mentioned protective case is used to be installed on an electronic device. When the electronic device is used horizontally, the user's two hands support both ends of the electronic device. By providing at least two sets of sound holes on the side frame, the at least two sets of sound holes are respectively located on different surfaces of the side frame, and these sound holes are all connected with the sound holes of the electronic device through sound channels. That is to say, the sound emitted by the electronic device can at least be output from the sound holes in different positions, which is used to generally not block all the sound holes in different positions when the electronic device is operated, so the user experience will not be affected. In addition, by arranging sound holes on different surfaces, the sound originally output in one direction can be dispersed to output in different directions through the sound holes in different directions, thereby increasing the stereo surround effect of the sound.

One group of sound holes includes a plurality of first sound holes 110A, and the other group of sound holes includes a plurality of second sound holes 120A. Each sound hole is connected to a branch channel. As shown in FIG. 5, the sound passage 140 may include a plurality of first branch passages 140A and a plurality of second branch passages 140B. Each first branch passage 140A communicates with one first sound hole 110A, and each second branch passage 140B It communicates with a second sound hole 120A. The sound channel 140 may include a general channel 140C, and all branch channels are in communication with the general channel 140C.
图9为本发明另一个实施例中的保护壳的结构示意图，保护壳包括侧框100，所述侧框100至少用于贴靠电子设备的具有出声孔的部位，所述侧框100上设 置有用于与电子设备的出声孔连通的声音通道140，所述的侧框100上设置有至少两组声孔。其中一组声孔包括一个第一声孔110A，另一组声孔包括一个第二声孔120A。也就是说，图9所示的实施例与图1所示的实施例的区别在于，图1所示实施例中的一组声孔包括成排布置的多个小孔，图9所示实施例中的一组声孔实际上是一条长条形的声孔。图9所示的实施例中，第一声孔110A连通第一支通道140A，第二声孔120A连通第二支通道140B，第一支通道140A和第二支通道140B均与一个总通道140C连通，总通道140C用于连通电子设备的出声孔。各实施例中的声孔的通道的具体形状并不构成对本发明保护壳的限制，例如图1所示的声孔和横截面为圆形，也可以为椭圆形、三角形等；例如图9所示的声孔为直条形，也可以为弯曲的条形等。FIG. 9 is a schematic structural diagram of a protective case in another embodiment of the present invention. The protective case includes a side frame 100 at least for abutting against a part of an electronic device that has a sound hole, and the side frame 100 is A sound channel 140 for communicating with the sound hole of the electronic device is provided, and the side frame 100 is provided with at least two sets of sound holes. One group of sound holes includes a first sound hole 110A, and the other group of sound holes includes a second sound hole 120A. That is to say, the difference between the embodiment shown in FIG. 9 and the embodiment shown in FIG. 1 is that a group of sound holes in the embodiment shown in FIG. 1 includes a plurality of small holes arranged in rows, and the implementation shown in FIG. 9 The set of sound holes in the example is actually a long strip of sound holes. In the embodiment shown in FIG. 9, the first acoustic hole 110A communicates with the first branch channel 140A, and the second acoustic hole 120A communicates with the second branch channel 140B. Both the first branch channel 140A and the second branch channel 140B are connected to a general channel 140C. The main channel 140C is used to communicate with the sound hole of the electronic device. The specific shape of the channel of the sound hole in each embodiment does not constitute a limitation to the protective shell of the present invention. For example, the sound hole and the cross section shown in FIG. 1 are circular, or may be elliptical, triangular, etc.; The sound hole shown is a straight strip shape, or a curved strip shape.
如图1、图2和图4所示，保护壳均包括背壳200和连接背壳200的侧框100，电子设备安装在保护壳上时，背壳200用于保护电子设备的背部，提高保护壳对电子设备的包裹性。如图3所示，为了降低保护壳的重量且增强保护壳的散热性能，保护壳包括侧框100而不设置背壳200，也就是说，电子设备安装在保护壳上时，电子设备的背部可以直接暴露，从而便于散热。在一些实施例中，为了提高保护壳的散热性，也可以在设置有背壳200的保护壳上设置散热孔，即在背壳200上设置散热孔，从而既能保证对电子设备的包裹性，又兼具散热效果。As shown in Figure 1, Figure 2 and Figure 4, the protective shell includes a back shell 200 and a side frame 100 connected to the back shell 200.

When the electronic device is a mobile phone or a tablet computer, the user usually does not use his hands when watching videos or playing games. The two sets of sound holes are blocked, so as not to affect the user experience. In addition, by arranging sound holes on different surfaces, the sound originally output in one direction can be dispersed to output in different directions through the sound holes in different directions, thereby increasing the stereo surround effect of the sound.
在一些实施例中，保护壳的侧框100可以采用热塑性聚氨酯或弹性体橡胶等材质制成，当保护壳还包括背壳200时，背壳200可以采用聚碳酸酯、热塑性聚氨酯或弹性体橡胶等材质制成。当然，具体地材质选择也不构成对本申请的保护壳的限制，例如还可以采用金属侧框100、TPU侧框100等，背壳200也可以采用PC材料。In some embodiments, the side frame 100 of the protective shell may be made of thermoplastic polyurethane or elastomer rubber. When the protective shell further includes the back shell 200, the back shell 200 may be made of polycarbonate, thermoplastic polyurethane or elastomer rubber. Made of other materials. Of course, the specific material selection does not constitute a limitation to the protective shell of the present application. For example, metal side frames 100, TPU side frames 100, etc. may also be used, and the back shell 200 may also be made of PC materials.
在一些实施例中，为了提高保护壳的抗摔性能，可以至少使侧框100由弹性材料制成。还可以在保护壳的四个角设置气囊，从而使保护壳刷落时，通过气囊对保护壳起到缓冲作用，提高对电子设备的保护性能。In some embodiments, in order to improve the anti-fall performance of the protective case, at least the side frame 100 may be made of an elastic material. Airbags can also be arranged at the four corners of the protective shell, so that when the protective shell is brushed off, the airbag cushions the protective shell and improves the protection performance of the electronic equipment.
