[0056] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0058] Generally, terminal devices typically have two symmetrically arranged speakers, and the middle frame of the terminal device also has two opposing speaker channels. The sound emitted by each speaker can be transmitted from its corresponding speaker channel. In this way, the two speaker channels can form a stereo channel, and when the two speakers are working simultaneously, the terminal device emits stereo sound through this stereo channel.

[0059] However, current terminal devices can only form one stereo channel, resulting in poor stereo sound quality. For example, a terminal device with only one stereo channel only produces noticeable stereo sound when placed in one direction (e.g., horizontally), and the stereo sound is not noticeable when placed in another direction (e.g., vertically). Furthermore, when a user holds a terminal device with only one stereo channel, it easily blocks the speaker channels, further reducing the stereo sound quality.

[0060] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the installation of a speaker in a terminal device provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows a cross-sectional view of a speaker. The terminal device may include a mid-frame 100 and a plurality of speakers 200.

[0061] The middle frame 100 may include a plurality of side panels 101, wherein every two adjacent side panels 101 in the middle frame 100 form a corner 100a. For example, the plurality of side panels 101 can form an annular region. For instance, if there are four side panels 101, the annular region formed by these four side panels 101 is rectangular, thus the middle frame 100 has four corners 100a.

[0062] Multiple speakers 200 can be located at at least two target corners of multiple corners 100a. For example, the mid-frame 100 may further include a base plate 102 fixedly connected to one side of the side panel 101, and the terminal device may further include a speaker bracket a11. The speaker 200 is mounted in the speaker bracket a11, and the speaker bracket a11 can be fixed to the base plate 102 in the mid-frame 100 by screws, thereby mounting the speaker 200 into the terminal device. It should be noted that the terminal device may further include a display panel (not shown) and a battery cover (not shown). One side of the side panel 101 of the mid-frame 100 in the terminal device can be bonded to the display panel, and the other side can be bonded to the battery cover. Thus, a closed cavity can be formed in the terminal device through the display panel, mid-frame 100, and battery cover, and multiple speakers 200 can be located within this sealed cavity.

[0063] At least one of the two target ends forming the target corner has a sound channel 1011. This target end is the end of the side plate 101 closest to the target corner. That is, either one of the two target ends forming the target corner has a sound channel 1011, or both target ends forming the target corner have a sound channel 1011.

[0064] In this embodiment of the application, the speaker channels 1011 on the middle frame 100 form at least two sets of stereo channels, and each set of stereo channels may include a pair of speaker channels 1011 located on two opposite side plates 101 in the middle frame 100.

[0065] In this application, there are multiple ways to form at least two stereo channels. The embodiments of this application illustrate the following three possible ways:

[0066] The first possible approach is as follows: Figure 1As shown, there are at least two target corners, which are a pair of opposite corners of the middle frame 100. The terminal device includes two speakers 200, and each of the two target ends forming the target corner has a sound channel. Thus, the sound emitted by each speaker 200 can be transmitted through two sound channels. For example, the sound emitted by one speaker 200 is transmitted through sound channel b3 and sound channel a3; the sound emitted by the other speaker 200 is transmitted through sound channel a2 and sound channel b2. In this case, the sound channels on the middle frame 100 can form two sets of stereo channels; that is, sound channel b3 and sound channel a2 can form one set of stereo channels, and sound channel a3 and sound channel b2 can form another set of stereo channels.

[0067] The second possible approach is as follows: Figure 3 As shown, Figure 3 This is a schematic diagram of the installation of another type of speaker in a terminal device provided in this application embodiment. There are at least three target corners, which may include a set of opposite corners of the middle frame 100. The terminal device includes three speakers 200, and at least one of the two target ends forming the target corner has a sound channel. For example, the three speakers 200 are speaker A1, speaker A2, and speaker A3. Both target ends forming the target corner where speaker A1 is located have a sound channel, while only one of the two target ends forming the target corners where speakers A2 and A3 are located has a sound channel. Thus, the sound emitted by speaker A1 can be transmitted through two sound channels, and the sound emitted by speakers A2 and A3 can be transmitted through one sound channel. For example, the sound emitted by speaker A1 is transmitted through sound channels a1 and b1; the sound emitted by speaker A2 is transmitted through sound channel a2; and the sound emitted by speaker A3 is transmitted through sound channel a3. In this case, the speaker channels on the middle frame 100 can form two sets of stereo channels. That is, speaker channels a1 and a2 can form one set of stereo channels, and speaker channels b1 and a3 can form one set of stereo channels.

[0068] The third possible approach is as follows: Figure 4 As shown, Figure 4This is a schematic diagram of the installation of another type of speaker in the terminal device provided in this application embodiment. There are at least four target corners, including two sets of opposite corners of the middle frame 100. The terminal device may include four speakers 200. That is, the four speakers 200 are respectively located at the four corners 100a of the middle frame 100. Each target corner has a sound channel at both ends. For example, the four speakers 200 are speaker A1, speaker A2, speaker A3, and speaker A4. The sound emitted by speakers A1, A2, A3, and A4 can be transmitted through two sound channels. For example, the sound emitted by speaker A1 is transmitted through sound channels a1 and b1; the sound emitted by speaker A2 is transmitted through sound channels a2 and b2; the sound emitted by speaker A3 is transmitted through sound channels a3 and b3; and the sound emitted by speaker A4 is transmitted through sound channels a4 and b4. In this configuration, the speaker channels on the middle frame 100 can form four stereo channels. Specifically, speaker channels a1 and a2 can form one stereo channel, speaker channels b3 and b4 can form one stereo channel, speaker channels b1 and a3 can form one stereo channel, and speaker channels a4 and b2 can form one stereo channel.

[0069] Based on the three possible implementation methods described above, it is clear that in order for the speaker channels 1011 on the mid-frame 100 to form at least two stereo channels, it is necessary to ensure that at least two target corners include at least one set of diagonals of the mid-frame 100. In this embodiment, when the terminal device has at least two stereo channels, the stereo sound emitted by the terminal device is more pronounced whether the terminal device is placed horizontally or vertically, effectively improving the stereo sound effect emitted by the terminal device. Furthermore, when a user holds the terminal device, they may only block one speaker channel in a stereo channel, while the other stereo channels can still emit stereo sound, further improving the stereo sound effect emitted by the terminal device.

[0070] In summary, the terminal device provided in this application includes a mid-frame and a plurality of speakers. The mid-frame includes a plurality of side panels, which can form an annular region with a plurality of corners. The plurality of speakers can be located at at least two target corners of the plurality of corners. Since at least one of the two target ends forming the target corners has a sound channel, the sound channels on the mid-frame can form at least two sets of stereo channels. Thus, the stereo sound effect emitted by the terminal device through the at least two sets of stereo channels is better.

[0071] Regarding the number of sound-emitting surfaces in a loudspeaker, this application embodiment will illustrate the following two optional implementation methods as examples:

[0072] In the first feasible method, such as Figure 2 As shown, the speaker 200 in the terminal device may have a sound-emitting surface 201 facing the corner where the speaker 200 is located. For example, the angle α between the sound-emitting surface 201 of the speaker 200 and each side plate 101 of the corner where the speaker 200 is located is 45 degrees. In this way, the sound emitted from the sound-emitting surface 201 can be evenly emitted from the sound channel 1011 on the side plate 101 at the corner, thereby effectively improving the sound effect of the speaker 200.

[0073] In the second possible implementation, such as Figure 5 As shown, Figure 5 This is a schematic diagram illustrating the installation of another type of speaker in a terminal device provided in this application embodiment. The speaker 200 in the terminal device may have two sound-emitting surfaces 201, each facing one of the two side panels 101 at the corner where the speaker 200 is located. For example, each of the two sound-emitting surfaces 201 is parallel to the side panel 101 facing the corresponding side panel. This allows the sound emitted by the speaker 200 to be emitted from the two sound-emitting channels 1011 through the two sound-emitting surfaces 201, thereby effectively improving the sound effect of the speaker 200. Furthermore, when the speaker 200 forms a stereo channel, it can effectively improve the stereo sound effect.

[0074] Regarding the structure of the speaker channel, this application will illustrate the following two possible implementation methods.

[0075] In the first feasible method, such as Figure 2 As shown, each side panel 101 may include at least one speaker hole 1011a in its speaker channel 101. For example, sound emitted by the speaker 200 can be emitted through at least one speaker hole 1011a on the side panel 101. In this embodiment, the terminal device may further include a sealing mesh 400. The sealing mesh 400 covers the opening of the speaker channel 1011 facing the middle frame 100. This effectively prevents external dust and other impurities from entering the speaker 200.

[0076] In the second possible implementation, such as Figure 5 and Figure 6 As shown, Figure 6 yes Figure 5 A cross-sectional view of the provided loudspeaker. The sound channel 1011 on each side panel 101 can be a sound channel. The terminal device may also include a dust cover 500 located in the sound channel, the end of the dust cover 500 remote from the loudspeaker 200 possibly having a dust hole 501. For example, Figure 7This is a schematic diagram of the structure of the dust cover in the terminal device provided in this application embodiment. The dust hole 501 can be a nanopore, that is, the dust hole 501 can be a hole with a diameter of nanometers. In this way, the dust cover can effectively prevent external dust or water droplets from entering the speaker 200, and can also prevent sharp objects such as SIM card pins from being accidentally inserted into the dust hole 501 and damaging other dustproof structures inside the middle frame 100.

[0077] Optionally, the end of the dust cover 500 furthest from the speaker 200 can be flush with the outer surface of the side panel 101. In this way, the appearance of the dust cover 500 can be integrated with the mid-frame 100, improving the aesthetics of the terminal device.

[0078] In this embodiment, the terminal device may further include an annular buffer 300 located between the speaker 200 and the side panel 101, wherein the sound-emitting surface 201 of the speaker 200 may be located in the inner ring of the annular buffer 300. For example, the annular buffer 300 may be an elastic annular foam. In this way, the vibration generated by the speaker 200 during operation can be effectively absorbed by the annular buffer 300, thereby reducing the overall vibration of the terminal device and improving the user experience.

[0079] Optional, please refer to Figure 8 and Figure 9 , Figure 8 This is an assembly diagram of a card tray assembly in a terminal device provided in an embodiment of this application. Figure 9 This is a schematic diagram of a card tray provided in an embodiment of this application. The side plate 101 in the middle frame 100 may have a connecting groove 1012, with two openings in the connecting groove 1012 located on the outer and inner sides of the side plate 101, respectively. The terminal device may further include: a card holder 600, a card tray 700, an elastic mechanism 800, and a card pin 900.

[0080] The card holder 600 can be located within the annular area enclosed by multiple side panels 101. That is, the card holder 600 can be located within the enclosed cavity formed by the display panel, the middle frame 100, and the battery cover.

[0081] The card tray 700 is configured to assemble a user identification card and allow it to pass through the connection slot 1012 for installation within the card holder 600. For example, the user identification card may be a SIM (Subscriber Identity Module) card. After the card tray 700, with the user identification card assembled within it, is installed in the card holder 600, the user identification card can be electrically connected to a terminal device via the card holder 600. In this embodiment, the end face of the card tray 700 away from the card holder 600 may have a SIM card ejector tool slot 701 and a through hole 702. For example, the card tray 700 may include a frame 703 located within the card holder 600, and a cover plate 704 fixedly connected to one end of the frame 703. The SIM card ejector tool slot 701 may be located on the end face of the cover plate 704 away from the frame 703; the through hole 702 may be located on the cover plate 704, and the through hole 702 may penetrate the cover plate 704.

[0082] At least a portion of the elastic mechanism 800 is located within the card holder 600, and the elastic mechanism 800 has a force-receiving member 801. The elastic mechanism 800 is configured to eject the card holder 700 from the card holder 600 after the force-receiving member 801 is subjected to pressure. For example, the elastic mechanism 800 may further include a first link 800a and a second link 800b. The first link 800a may be connected to the side of the card holder 600, and the second link 800b may be located within the card holder 600. A first end of the first link 800a has the force-receiving member 801, and a second end of the first link 800a is connected to the first end of the second link 800b. The second end of the second link 800b may abut against the card holder 700. In this way, when the force-bearing component 801 is subjected to pressure, it can push the first link 800a, which in turn drives the second link 800b to rotate. The second end of the second link 800b applies a force to the card holder 700 toward the outer side of the middle frame 100, thereby enabling the card holder 700 to pop out from the card seat 600.

[0083] like Figure 10 As shown, Figure 10 This is a diagram showing the card holder in ejected and non-ejected states according to an embodiment of this application. The card pin 900 can be engaged in the card pin slot 701. The card pin 900 is configured such that, after being removed from the card pin slot 701, it passes through the through hole 702 and applies pressure to the force-receiving member 801 to eject the card holder 700 from the card base 600. For example, when it is necessary to eject the card holder 700 from the card base 600, the card pin 900 can be removed from the card pin slot 701, passed through the through hole 702, and abutted against the force-receiving member 801. After applying a certain pressure to the force-receiving member 801, the first connecting rod 800a can be pushed. The first connecting rod 800a drives the second connecting rod 800b to rotate, thereby ejecting the card holder 700 from the card base 600.

[0084] In the embodiments of this application, such as Figure 11 As shown, Figure 11 This is a schematic diagram of a SIM card ejector pin provided in an embodiment of this application. A first engaging member 701a may be present in the SIM card ejector pin slot 701, and a second engaging member 901 may be present on the SIM card ejector pin 900. The second engaging member 901 is configured to engage with the first engaging member 701a. In this way, after the SIM card ejector pin 900 is installed in the SIM card ejector pin slot 701, the stability of the SIM card ejector pin 900 can be effectively improved, preventing the SIM card ejector pin 900 from falling out of the SIM card ejector pin slot 701. For example, the first engaging member 701a may include an engaging protrusion, and the second engaging member 901 may include an engaging groove. When the SIM card ejector pin 900 is located in the SIM card ejector pin slot 701, the engaging protrusion can cooperate with the engaging groove to complete the installation of the SIM card ejector pin 900 and the SIM card ejector pin slot 701.

[0085] To prevent the SIM card pin 900 from detaching from the mid-frame 100, such as Figure 9 and Figure 12 As shown. Figure 12 This is a cross-sectional view of the SIM card pin located in the through hole according to an embodiment of this application. The through hole 702 can be located at the bottom of one end of the SIM card pin groove 701. The inner wall of the through hole 702 can have a limiting groove 702a. One end of the limiting groove 702a communicates with the annular region, and the other end of the limiting groove 702a is closed. That is, the end of the limiting groove 702a located on the inner side of the side plate 101 communicates with the annular region formed by the multiple side plates 101, and the end of the limiting groove 702a near the outer side is closed. One end of the SIM card pin 900 has a limiting protrusion 902, which is located in the limiting groove 702a and can rotate within the limiting groove 702a. Thus, when the SIM card pin 900 passes through the through hole 702 into the annular region, the engagement of the limiting groove 702a and the limiting protrusion 902 guides the SIM card pin 900. When the SIM card pin 900 is removed from the through hole 702, the other end of the limiting groove 702a is closed. Therefore, the SIM card pin 900 is prevented from falling off the middle frame 100. Furthermore, the SIM card pin 900 can rotate within the limiting groove 702a, allowing it to pass through the through hole 702 into the annular region, or to rotate into the SIM card slot 701, whereby the SIM card pin 900 can close the through hole 702.

[0086] In this embodiment, the shape of the through hole 702 and the cross-sectional shape of the SIM card pin 900 can be the same, and both can be any shape other than a circle. For example, when the through hole 702 is square, the cross-sectional shape of the SIM card pin 900 is also square; when the through hole 702 is pentagonal, the cross-sectional shape of the SIM card pin 900 is also pentagonal. This avoids the situation where the limiting protrusion 902 on the SIM card pin 900 cannot engage with the limiting groove 702a after the SIM card pin 900 rotates when a part of it is located in the annular region.

[0087] In related technologies, the terminal device includes: a card holder, a card tray, a card pin, a card pin hole, and a linkage mechanism. A side plate in the middle frame has a connecting slot communicating with a cavity formed by the middle frame and the battery cover. The card holder is located within this cavity. The card tray is configured to hold a user identification card and passes through the connecting slot to be installed within the card holder. The linkage mechanism is connected to the card holder. The card pin hole is located on the side plate, communicating with the cavity formed by the middle frame and the battery cover. The pin hole is configured to allow the card pin to enter the cavity from the outside of the middle frame and to push the linkage mechanism. When it is necessary to eject the card tray from the card holder, the card pin can pass through the card pin hole and push the linkage mechanism, which can then eject the card tray from the card holder. However, the card pin is inconvenient to carry, and the card pin hole is easily clogged by external impurities, preventing the card pin from passing through and thus preventing the user from replacing their user identification card.

[0088] In this embodiment, the SIM card pin 900 can be mounted on the SIM card tray 700 and does not need to be carried around. When the SIM card tray 700 is not ejected, the SIM card pin 900 is located in the SIM card pin groove 701 and engages with the SIM card pin groove 701. The SIM card pin 900 can also seal the through hole 702, preventing the through hole 702 from being blocked by external impurities. When the SIM card tray 700 is ejected, the SIM card pin 900 is limited by one end of the limiting groove 702a, which can prevent the SIM card pin 900 from falling out of the middle frame 100.

[0089] Please refer to Figure 13 and Figure 14 , Figure 13 This is an assembly diagram of a button in a terminal device provided in an embodiment of this application. Figure 14 This is an exploded view of a button in a terminal device provided in this application embodiment. The side panel 101 in the middle frame 100 has a receiving cavity (not shown in the figure), which may have a first opening 101a and a second opening 101b. The first opening 101a may be located on the outer surface of the side panel 101, and the second opening 101b may be located on the surface of the side panel 101 opposite to the bottom plate 102. That is, the surface containing the first opening 101a intersects the surface containing the second opening 101b; for example, the surface containing the first opening 101a is perpendicular to the surface containing the second opening 101b.

[0090] In this embodiment, the terminal device may further include a button 1000 and a snap-fit ​​connector 1100. The button 1000 is disposed within a receiving cavity on the side plate 101 through a first opening 101a, and a first end of the button 1000 abuts against the inner wall of the receiving cavity. For example, the first end of the button 1000 has a pressure plate b11. When the button 1000 is installed into the receiving cavity on the side plate 101, the side of the pressure plate b11 near the side plate 101 abuts against the inner wall of the receiving cavity, so that the first end of the button 1000 will not fall out of the receiving cavity after the button 1000 is installed into the receiving cavity.

[0091] The snap-fit ​​element 1100 can be configured to extend into the receiving cavity from the second opening 101b of the receiving cavity, snap-fit ​​with the second end of the button 1000, and abut against the inner wall of the receiving cavity. In this way, after the button 1000 is installed in the receiving cavity, it can be ensured that the second end of the button 1000 will not fall out of the receiving cavity.

[0092] In related technologies, the receiving cavity of the side panel in the terminal device, in addition to having a first opening and a second opening, also requires an additional slot in the middle frame. After the button is assembled into the receiving cavity, a tab can be inserted into the slot to prevent the button from falling out of the receiving cavity. However, the slot on the side panel reduces the structural strength of the side panel. In addition, when it is necessary to remove the button from the receiving cavity, the pressure plate needs to be pulled out of the slot. Since the thickness of the pressure plate is usually small, it is very easy to break during the process of pulling out the pressure plate.

[0093] In this embodiment, there is no need to create an additional slot on the side plate 101. The snap-fit ​​member 1100 can simply enter the receiving cavity through the second opening 101b and snap into the second end of the button 1000, ensuring high structural strength of the side plate 101. Furthermore, since the snap-fit ​​member 1100 needs to snap into the second end of the button 1000, to ensure a tight connection, the snap-fit ​​member 1100 needs to be relatively thick. This prevents breakage during removal of the snap-fit ​​member 1100 from the second end of the button 1000.

[0094] Optional, such as Figure 14 As shown, the sidewall of the second end of the button 1000 may have a mounting protrusion 1001, and the snap-fit ​​member 1100 may have a mounting opening 1101. The snap-fit ​​member 1100 is configured to extend into the receiving cavity from the second opening 101b, such that the mounting opening 1101 engages with the mounting protrusion 1001. In this application, at least one of the snap-fit ​​member 1100 and the mounting protrusion 1001 may be made of an elastic material. For example, at least one of the snap-fit ​​member 1100 and the mounting protrusion 1001 may be made of rubber. This facilitates the snap-fit ​​of the snap-fit ​​member 1100 with the mounting protrusion 1001 after installation.

[0095] In this embodiment, the shape of the mounting opening 1101 in the snap-fit ​​member 1100 and the shape of the cross-section of the mounting protrusion 1001 in the button 1000 can be the same; both can be any shape other than a circle. For example, when the shape of the mounting opening 1101 is square, the cross-section of the mounting protrusion 1001 in the button 1000 is also square. This prevents the snap-fit ​​member 1100 from rotating on the mounting protrusion 1001 after snapping it into place, thus ensuring the contact between the snap-fit ​​member 1100 and the inner wall of the receiving cavity, preventing the second end of the button 1000 from falling out of the receiving cavity.

[0096] For example, please refer to Figure 15 , Figure 15 This is an exploded view of a button and a snap-fit ​​connector in a terminal device provided in this application embodiment. The side of the mounting protrusion 1001 may have a snap-fit ​​groove 1001a, and the mounting opening 1101 may include a first mounting opening 1101a and a second mounting opening 1101b that are connected. A first side of the first mounting opening 1101a communicates with a second side of the second mounting opening 1101b, and the length of the first side is less than the length of the second side. The first mounting opening 1101a is configured to allow the mounting protrusion 1001 to pass through, and the second mounting opening 1101b is configured to engage with the mounting protrusion 1001 in the snap-fit ​​groove 1001a.

[0097] For example, when the mounting opening 1101 in the snap-fit ​​member 1100 is square, the shapes of the first mounting opening 1101a and the second mounting opening 1101b are both square. The snap-fit ​​groove 1001a in the mounting protrusion 1001 can be a rectangular annular groove. In this way, after the snap-fit ​​member 1100 is snapped into the mounting protrusion 1001, at least a portion of the snap-fit ​​member 1100 (the portion at the edge of the second mounting opening 1101b) is located within the snap-fit ​​groove 1001a in the mounting protrusion 1001, ensuring high stability of the snap-fit ​​between the snap-fit ​​member 1100 and the mounting protrusion 1001.

[0098] In this embodiment, the snap-fit ​​component 1100 may also have a disassembly hole 1102, which is configured to cooperate with a disassembly tool to remove the snap-fit ​​component 1100 from the second opening 101b. Thus, by using the disassembly hole 1102 in conjunction with the disassembly tool, it is convenient to remove the snap-fit ​​component 1100 from the mounting protrusion 1001. For example, when it is necessary to remove the button 1000 from the receiving cavity, tweezers or other disassembly tools can be used to clamp the snap-fit ​​component 1100 from the disassembly hole 1102 and remove it from the second opening 101b, thereby removing the button 1000.

[0099] Optional, such as Figure 14As shown, the side wall of the button 1000 also has a protrusion 1002. The terminal device may further include an electronic switch a11 located inside the receiving cavity, the electronic switch a11 being connectable to the inner wall of the receiving cavity, and the electronic switch a11 having a contact a12. After the button 1000 is located in the receiving cavity, the protrusion 1002 of the button 1000 can contact the contact a12 of the electronic switch a11. In this case, when the button 1000 is pressed, the button 1000 can move towards the electronic switch a11, thereby causing the contact a12 in the electronic switch a11 to be pressed by the protrusion 1002 of the button 1000. After the contact a12 in the electronic switch a11 is pressed, the electronic switch a11 can send a command to the controller in the terminal device to realize the control function of the button 1000.

[0100] For example, the electronic switch a11 can be a switch for adjusting the volume in a terminal device. When the button 1000 is installed in the receiving cavity, pressing the button 1000 causes the protrusion 1002 on the button 1000 to press the contact on the electronic switch a11 to achieve volume control.

[0101] In summary, the terminal device provided in this application includes a mid-frame and multiple speakers. The mid-frame includes multiple side panels that can form an annular region with multiple corners. The multiple speakers can be located at at least two target corners of the multiple corners. Since at least one of the two target ends forming the target corners has a sound channel, the sound channels on the mid-frame can form at least two sets of stereo channels. Thus, the stereo sound effect emitted by the terminal device through these at least two sets of stereo channels is better.

[0102] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0103] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
