Abstract
Description
Technical Field
[0001] This application relates to a protective case for a tablet electronic device. Background Technology
[0002] Tablet electronic devices are very common, such as tablets. Tablet electronic devices include a display screen and speakers, with the speakers typically located on the side of the device. Many people like to use a protective case to protect their electronic devices from bumps and knocks. These cases usually have openings on their sides to prevent the sound from being affected by the case. However, if your hand touches and blocks these openings while holding the device, the sound from the speaker will be weakened. Furthermore, most current protective cases have side openings, causing the sound from the tablet to travel from the side openings towards the side of the case, rather than towards the user. Additionally, some tablet electronic devices have two speakers, but these are usually positioned on one side of the device, causing the sound to be off-center. Summary of the Invention

Similar or analogous designations in the drawings and description have been used to refer to similar or analogous parts of this application. As used herein, the terms “first,” “second,” and “third,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of individual components.
[0042] Tablet electronic devices include tablet computing devices, etc. For example... Figure 1 As shown, in some tablet electronic devices 20, the tablet electronic device 20 is provided with two speakers 201, and the speakers 201 are located on the side of the tablet electronic device 20. The side wall of the tablet electronic device 20 is provided with a sound hole 202, and the sound of the speakers 201 can be transmitted from the sound hole 202.
[0043] This application provides a protective case 10 for a tablet electronic device 20, such as... Figure 2As shown, it includes a rear wall 104 and a first side wall 101, a second side wall 102, and two third side walls 103 arranged around the perimeter of the rear wall 104. The first side wall 101 and the second side wall 102 are arranged opposite to each other, and the two third side walls 103 are arranged opposite to each other. The first side wall 101, the second side wall 102, the two third side walls 103, and the rear wall 104 form a receiving groove 105 for accommodating the flat panel electronic device 20.
[0044] like Figures 3 to 6 As shown, in some embodiments, the first sidewall 101 is provided with a first side groove 1011 and a second side groove 1012, which correspond to the two speakers 201 of the tablet electronic device 20, respectively. The first side groove 1011 and the second side groove 1012 have the same structure; the structure of the first side groove 1011 will be described using this example. The first side groove 1011 is located on the inner wall of the first sidewall 101 and is formed by a recess inward from the inner wall. The first side groove 1011 extends toward the edge of the first sidewall 101 and forms an opening 1014 at the edge of the first sidewall 101, allowing sound from the speakers 201 to be emitted from the first side groove 1011. Figure 6 As shown, the tablet electronic device 20 is housed in the protective sleeve 10. The sidewall of the tablet electronic device 20 is fitted against the inner wall of the first sidewall 101, so that the sidewall of the tablet electronic device 20 and the first side groove 1011 form a one-way channel for sound transmission. One side sound hole 202 of the tablet electronic device 20 communicates with the first side groove 1011. The sound emitted by the speaker 201 enters the first side groove 1011 from the sound hole 202 and propagates along the guide of the first side groove 1011 (as shown by the arrow in the figure), thereby directing the sound emitted by the speaker 201 to the user.
[0045] The above embodiment provides a first side slot 1011 and a second side slot 1012, which correspond to two speakers 201 of the tablet electronic device 20. If the tablet electronic device 20 has one or more speakers 201, one or more side slots can be provided accordingly.
[0046] Furthermore, taking the tablet electronic device 20 in the above embodiment as an example, the tablet electronic device 20 is provided with two speakers 201, and the speakers 201 are located on the side of the tablet electronic device 20. The side wall of the tablet electronic device 20 is provided with a sound hole 202, and the sound from the speakers 201 can be transmitted from the sound hole 202. Since the two speakers 201 are located on the same side, the sound emitted by the tablet electronic device 20 will be offset, that is, the sound will deviate from the center of the tablet electronic device 20.
[0047] like Figures 7 to 13As shown, to improve the aforementioned sound offset, in some embodiments, the inner wall of the rear wall 104 is provided with an inwardly recessed rear groove 1041, which extends between the first side wall 101 and the second side wall 102. For example... Figure 8 and Figure 12 As shown, in this embodiment, the inner wall of the first sidewall 101 is recessed inward to form a third side groove 1013. The third side groove 1013 extends toward the edge of the first sidewall 101 and passes through the edge of the first sidewall 101 to form an opening at the edge. The third side groove 1013 extends toward the rear wall 104 and communicates with the first end of the rear groove 1041. Figure 10 and Figure 13 As shown, the inner wall of the second sidewall 102 is recessed inward to form a fourth side groove 1021, which extends toward the rear wall 104 and communicates with the second end of the rear groove 1041. Wherein, as Figure 13 As shown, the fourth side groove 1021 does not extend beyond the edge of the second side wall 102, meaning that the fourth side groove 1021 can only connect to the rear groove 1041 in one direction. Please refer to... Figure 11 As shown, the tablet electronic device 20 is housed in a protective sleeve 10. The fourth side slot 1021, the rear slot 1041, the third side slot 1013, and the outer casing of the tablet electronic device 20 form a sound propagation channel. The outer side of the tablet electronic device 20 is fitted against the inner wall of the protective sleeve 10. One side sound hole 202 of the tablet electronic device 20 communicates with the fourth side slot 1021. Sound emitted by the speaker 201 enters the fourth side slot 1021 from the sound hole 202 and propagates along the aforementioned guiding channel (as shown by the arrow in the figure). Figure 7a yes Figure 7 Another implementation scheme involves a change in the position of the fourth side channel 1021, which will not be elaborated here. Different directional guide channels can meet the needs of different users.
[0048] like Figure 7 and Figure 8 As shown, the second sidewall 102 is provided with a fifth side groove 1022, which is formed by an inward recess from the inner wall of the second sidewall 102. The fifth side groove 1022 extends toward the edge of the second sidewall 102 and passes through the edge of the second sidewall 102 to form an opening at the edge. In this embodiment, the sound emitted by one of the two speakers 201 of the tablet electronic device 20 is guided by the fourth side groove, the rear groove 1041, and the third side groove 1013 and emitted on one side of the first sidewall 101; the sound emitted by the other speaker 201 is guided by the fifth side groove 1022 and emitted on one side of the second sidewall 102. The above solution enables the sound of the tablet electronic device 20 to be emitted from both sides of the device, thereby improving the sound offset situation.
[0049] like Figure 14 As shown, in some embodiments, a through hole 1023 may be formed in the side wall of the fifth side groove 1022, through which the sound of the speaker 201 can be transmitted. If the through hole 1023 is blocked, the sound can be transmitted through the opening of the second side wall 102 along the fifth side groove 1022.
[0050] In some embodiments, the sound is not necessarily directed to the opposite side, but may also be directed to the side. For example... Figure 15 As shown, the second sidewall 102 is provided with a fourth side groove 1021, and the third sidewall 103 is provided with a sixth side groove 1031. The sixth side groove 1031 is formed by an inward recess from the inner wall of the third sidewall 103. The sixth side groove 1031 extends toward the edge of the third sidewall 103 and passes through the edge of the third sidewall 103 to form an opening at the edge. The sound propagation guiding channel is composed of the fourth side groove 1021, the rear groove 1041, the sixth side groove 1031, and the bottom shell of the tablet electronic device 20.
[0051] like Figure 8 and Figure 16 As shown, to improve heat dissipation, the protective sleeve 10 of this application is also provided with a docking structure to cooperate with an external heat sink. The docking structure includes a heat-conducting structure 1043, which has a certain conductive area and is disposed on the rear wall 104. The figure shows one embodiment of this application, in which the heat-conducting structure 1043 is circular and embedded in the rear wall 104.
[0052] In some embodiments, the thermally conductive structure 1043 is a monolithic structure, such as a thermally conductive silicone sheet.
[0053] In some embodiments, the thermally conductive structure 1043 is a multilayer structure, such as... Figure 16 As shown, the thermally conductive structure 1043 includes three layers: a first thermally conductive silicone layer 10431, a second thermally conductive silicone layer 10431, and a metal layer 10432 located between the first thermally conductive silicone layer 10431 and the second thermally conductive silicone layer 10431.
[0054] In some embodiments, to accommodate a magnetically connectable heat dissipation device, a ring-shaped first magnetic member 1042 is provided on the outer side of the heat-conducting structure 1043, and the first magnetic member 1042 can be embedded in the rear wall 104. For example, as Figure 16As shown, the inner side of the rear wall 104 is provided with an annular groove, and a circular hole is provided in the middle of the annular groove. The first magnetic attractor 1042 is embedded in the annular groove, and the heat-conducting structure 1043 is installed in the circular hole. The heat-conducting structure 1043 adopts the aforementioned three-layer structure, with the first thermally conductive silicone layer 10431 located within the receiving groove 105 of the protective sleeve 10. The radius of the first thermally conductive silicone layer 10431 is larger than the radii of the other two layers, and the first thermally conductive silicone layer 10431 can cover the first magnetic attractor 1042. The purpose is to provide a larger contact area for the first thermally conductive silicone layer 10431, thereby improving the efficiency of heat transfer. Additionally, it allows for a larger contact area between the heat-conducting structure 1043 and the rear wall 104, resulting in a more secure connection between the two. The first magnetic attractor 1042 can be a magnet, requiring the heat dissipation device to have a magnet component with opposite magnetism or a ferromagnetic metal component; the first magnetic attractor 1042 can also be a ferromagnetic metal, requiring the heat dissipation device to have a magnet component. Ferromagnetic metals include iron, cobalt, nickel, and gadolinium.
[0055] In some embodiments, the first thermally conductive silicone layer 10431 protrudes slightly from the bottom wall. After the tablet electronic device 20 is housed in the protective sleeve 10, the bottom of the tablet electronic device 20 can come into closer contact with the first thermally conductive silicone layer 10431 to achieve better heat conduction.
[0056] In some embodiments, such as Figure 16 As shown, a second magnetic attachment 1032 is installed on the inner wall of one of the third sidewalls 103. Some tablet electronic devices 20 have a stylus, which can selectively attach to the outer side of the third sidewall 103 located on the second magnetic attachment 1032. The second magnetic attachment 103 can be a magnet, requiring the stylus to have a magnet accessory with opposite magnetism or a ferromagnetic metal accessory; the second magnetic attachment 103 can also be a ferromagnetic metal, requiring the stylus to have a magnet accessory. Ferromagnetic metals include iron, cobalt, nickel, and gadolinium, etc. Furthermore, the stylus can be understood as one type of external accessory, which also includes ornaments or other connectable devices.
[0057] The above descriptions are merely examples of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
