[0044] Detailed description of the attached figures

[0045] This application will be described with reference to the included figures and diagrams. Figure 1A The diagram shows a top isometric view of application 10, which includes a body 15 containing a battery and all electronic components that allow wired and / or wireless charging of devices such as smartphones, as well as a specially designed thin sound tube that amplifies the decibels of sound waves from a device placed in a support slot 30. The application features a charging outer protective cover 20 made of a flexible material surrounding the body 15. The charging outer cover 20 includes an opening protrusion 25 located at an end 26, which facilitates the deployment of the charging outer protective cover. Figure 1B The lower isometric view shows the anti-slip pad 35 improving the fixation of the present application 10 to the surface on which the present application is placed.

[0046] Figure 2A and Figure 2B The deployment sequence of the charging cover 50 of this application 40 is shown. Figure 2A The method of unfolding the first section 55 of the charging cover 50 is shown, that is, pulling the front end 56 where the opening protrusion 60 is located separates the metal plate 79 on the main body 45 from the magnet 85 that secures the charging cover 50 in the closed position. Figure 2B The deployment of the second section 80 of the charging cover 50 is shown, exposing the anti-slip pad 90 located in the body 45 of the present application 40. These views show that, located on the left side of the body 45, are an on / off button 65, a USB-C or similar port 70 for power input allowing charging of the battery located inside the present application 40, and two or more USB-A or similar ports 75 for power output allowing charging of other devices connected via cables.

[0047] Figure 3 A left-side view of the present application 95 with the charging cover 105 fully extended is shown. The fourth segment 135 of the charging cover 105 is fixed inside the body 100 of the present application 95, and due to the flexibility of its material, this segment rotates about axis 140, allowing the first segment 115, second segment 110, and third segment 145 of the charging cover 105 to form a triangle, serving as a support for placing a smartphone, tablet, or other similar device on the present application 95. The magnet 130 of the first segment 115 of the charging cover 105 is connected to a metal plate 125 included in the lower portion of the body 100 of the present application 95 to hold the charging cover 105 in the extended position. When the charging cover 105 is extended, the device (tablet or smartphone) rests on the third segment 145 at an angle 120 of approximately 65° relative to the horizontal direction, allowing the user to comfortably view the device. A voice input port 142 is included on the front top 132 of the present application 95 and is connected via a conduit 143 to a support slot (…). Figure 1A and Figure 1B Hole 141 on (30) of the present application. Hole 141 is aligned with the microphone of the smartphone installed in the present application 95 and allows the user's voice or speech to be clearly perceived.

[0048] exist Figure 4A The image shows an isometric view of this application 150, with the charging cover 160 in an unfolded position, ready to hold a smartphone, tablet, or other similar device. The smartphone or other device can be mounted in a support slot 170 located on the body 155 of this application 150, supported by a third segment 165 of the charging cover 160 at approximately 65° to the horizontal. On the upper front portion 154 of the body 155, a metal plate 180 and a voice input port 175 are visible; these metal plates hold the charging cover 160 closed. Figure 4B This is an isometric view of application 150, showing the lateral telescopic arm 185 in the extended position. This lateral telescopic arm 185 serves as a support for placing application 150 in a horizontally tilted position and raising the phone to a height of approximately 35mm to 50mm above the base [e.g., above a tabletop], thereby allowing the tilt position to be adjusted between 90° and approximately 65° relative to the base. To retract the telescopic arm 185, the release button 190 needs to be pressed and pushed into the charging cover 160.

[0049] Figure 5AAn isometric view of application 195 is shown with the charging cover 205 unfolded and placed in an inclined position. The smartphone is mounted in a support groove 250 located on the body 200 and supported at the back by the third section 210 of the charging cover 205 and at the bottom by support pins 220 placed on the side edges of the charging cover 205. One or more input holes 240 are provided within the support groove 250, preferably only one, through which sound waves emitted by the smartphone or other device enter from the smartphone's speaker. Figure 6 The special thin sound tube 270 described in the text, and sound waves pass through the input sound tube ( Figure 6 The sound is amplified in the 270) and emitted from the front grille 245. There is also a microphone hole 241 in the support groove 250. The sound transmitted from the voice input hole 242 at the front upper part of the present application comes out through the microphone hole and directly reaches the microphone of the smartphone installed in the present application 195, so as to maintain clear reception of voice and sound during video calls. Figure 5B This is a left-side view of the application, showing how the telescopic arm 215 functions as a support in a tilted position and allows the phone's angle to be adjusted to different angles, starting at 90° to the horizontal (or tabletop) and going up to an adjustable tilt position 235 of approximately 65° above the horizontal, thus providing the user with different viewing options.

[0050] Figure 6 This is a left-side view of application 255, showing how sound waves 262 from a device such as a smartphone enter through an input port 265 located within a support groove 260 and propagate along a sound tube 270. This sound tube 270 draws the sound waves out of the input port 265 and guides them through the top 272 of the sound tube of application 255 and extends to the rear 295, where it makes a 180° turn and returns to the front along the bottom 300 of the sound tube 270. This path amplifies the decibel level of the sound, which is then amplified by the output grille 275 at the front. Application 255 has an internal compartment 285 containing a rechargeable battery (see...). Figure 8 (365), connection ports, and a PCB for managing the power charging function (see [reference]). Figure 8 (370).

[0051] Figure 7A and Figure 7B This illustrates how sound waves from a speaker of a smartphone or other device connected to an audio input port pass through the support base located in this application (see [link]). Figure 6The sound wave enters the sound tube 345 at a downward angle of approximately 65° 350 through the inlet hole 348 on the upper section 360 of the sound tube 345, and contacts the curved or flat inner wall 355 in the upper section 360 of the sound tube 345, driving the sound wave inward and guiding it through a zigzag path in the top 375 through a conduit from the front 365 to the rear 370, where the conduit forms a 180° turn 380, thereby connecting the upper portion 360 and the lower portion 385 of the sound tube 345. Thus, the sound wave returns from the rear 370 to the front 365 in a zigzag path in the bottom 390 to propagate through the outlet grille 395 at the front region 366. The length of the wave path within the sound tube 345 can be from 400 mm to 600 mm, preferably 500 mm, and has an average dimension of approximately 22 mm wide by 3 mm high along this path. At the sound outlet grille 395, the sound tube 345 extends outward to the maximum extent to have an end opening of approximately 60 mm to 100 mm wide, preferably 78 mm wide, and a tube wall height of preferably 15 mm to 35 mm, preferably 22.5 mm high.

[0052] Figure 7C and Figure 7D A U-shaped sound tube was shown, replacing... Figure 7A and Figure 7B The use of zigzag-shaped sound tubes seen in the text. Figure 7C An isometric top front view of a U-shaped sound tube 400 is shown, in which sound waves 405 enter the input port 410, encounter an inclined surface 415, and are guided along the interior of the tube. The U-shaped sound tube 400 forms a 180° turn 427 from the front 420 to the rear 425 and returns to the mouth 430. The sound tube has an initial width 422 between 10 mm and 20 mm, preferably 15 mm, which increases along its path to a final width 424 between 40 mm and 50 mm, preferably 45 mm, at the mouth 430 of the U-shaped sound tube; similarly, the height of this sound tube 400 is between 3 mm and 7 mm, preferably 5 mm, and the total length of the wave path is between 400 mm and 600 mm, preferably 500 mm. Figure 7D This is an isometric front view of the U-shaped sound tube 400 from below; it shows how sound waves 405 from the input port 410 propagate within the U-shaped sound tube 400 from the front 420 to the rear 425, forming a 180° turn 427 and then returning to the front of the sound tube 400.

[0053] Figure 7E and Figure 7F It shows Figure 7C and Figure 7D Another alternative to the U-shaped sound tube shown. Figure 7EA top-down isometric view of this alternative is shown, in which sound 434 enters the sound tube 432 through the input port 436. The sound is conducted through the bottom right section 435 to the rear region 439 of the sound tube 432, then forms a 180° upward bend 438, returns a short distance, forms another 180° right bend 437 in a rearward direction, and then forms another 180° downward bend 441. The sound is conducted through the lower left section 442 of the sound tube 432 to propagate through the front sound grille 444. The length of this U-shaped sound tube alternative is between 500 mm and 700 mm, preferably 600 mm. Figure 7F An isometric view from below is shown, illustrating the sound path of the sound tube.

[0054] Figure 7G It shows Figure 7A and Figure 7B The top-down, front-view, isometric view of an alternative to the zigzag tube 460 design shown, wherein the angles of the zigzag curves 466 and 470 of the tube path are less than 180° (between 120° and 150°), achieving a smoother sound path within the tube 460. Compared to... Figure 7A and Figure 7B Similar to the zigzag sound tube shown, sound 464 enters the sound tube input hole 462 and reaches the rear region 468 along the zigzag path 463, where it forms a 180° turn 467 downward and returns to the front part 469, and is transmitted along the zigzag path 465 and through the sound outlet grille 472 of the front part 469 of the sound tube 460. Figure 7H The same trajectory is shown in the isometric view from the front and from below.

[0055] Figure 8This is an isometric view of application 500, showing details of the electronic components for wired and wireless power bank functionality. Inside the main body 505 of application 500 is a rechargeable lithium-ion battery or other type of rechargeable battery 520 with a capacity between 5,000mAh and 30,000mAh, preferably 10,000mAh. This battery is connected via cable 525 to a PCB 530 that controls the charging and discharging of the battery 520. Included on the PCB 530 are an on / off button 535 with an LED indicator showing the battery level, and a power input port 540, preferably USB-C, USB-A, Micro USB, or Lightning type. Using this power input port, the rechargeable battery 520 inside application 500 can be connected via cable to another device, such as a laptop computer, or charged by connecting it to a power outlet or other power source using an A / C adapter. Included on the PCB 530 are two or more USB-A output ports or other types of ports 545, which can be connected to other devices to provide charging from the rechargeable battery 520 built into this application 500. A Qi-type or similar type wireless antenna 555 is connected to the PCB 530 via a flexible cable 550. This wireless antenna is located in the third segment 515 of the charging cover 510 to provide fast wireless power charging of 15W or higher to smartphones or devices compatible with this type of charging feature placed near the wireless antenna 555.

[0056] Figure 9A An isometric view of the present application 560 with the charging cover 565 in the closed position is shown. In this position, a smartphone 570 or other similar device with wireless charging capability can be wirelessly charged simply by placing it on the present application 560 and... Figure 8 Simply turn on the ON / OFF switch 535 as described above. Figure 9B The application 560 is shown with the charging cover 565 unfolded in a vertically tilted position, which allows the use of the smartphone 570 and easy viewing of the screen while wirelessly charging is being performed.

[0057] Figure 10AThis is a rear isometric view of the present application 575 in a vertically tilted position, with the charging cover 580 unfolded. In this view, a support flap 585 can be seen unfolding from the rear of the third section 600 of the charging cover 580, rotating outwards by 180°, acting as a support for placing the present application 575 in a horizontal or tilted position, at an angle of approximately 65° to the back (e.g., a tabletop) for comfortable viewing of the smartphone screen. The support flap 585 includes a support protrusion 590 that, when rotated, reaches and contacts support pins 605 (where the smartphone or other accessories rest when placed horizontally on the present application 575), limiting the rotation of the support flap 585 to 180°, thereby maintaining the tilted position of the present application 575. When the charging cover 580 is fully folded, the support protrusion 590 is stored within the pocket 595 of the main body 610. Figure 10B The diagram illustrates how the support flap 585 contacts the support pin 605 during rotation, thereby securing the present application 575 in an inclined position and raising the front of the application for a more comfortable viewing angle for the user of a smartphone or other connected device. The support flap 585 consists of a single frame or multiple frames attached to a flexible plastic material, similar to the support flaps commonly used in tablet covers on the market.

[0058] exist Figure 11A The image shows an isometric view of version 615 of this application with the charging cover 620 unfolded, including a lateral telescopic arm 625 on which a smartphone 635 is mounted. This lateral arm allows the application 615 to be positioned laterally or at a horizontal tilt, and its height can be adjusted to control the viewing angle and allow the user to view the smartphone screen 635 or other connected devices more comfortably. Figure 11B This is an isometric view of the present application 615 and its deployed charging cover 620, which includes a folding flip stand 630 version. The folding flip stand 630 unfolds 180° from the inside of the charging cover 620 and serves as a support for raising the smartphone, thereby making the viewing angle of the smartphone comfortable when the present application 615 is placed in tilt mode.

[0059] Figure 12A The following is shown: [Demonstration of] [the process] in an anechoic chamber Figures 7C to 7H The table shows the data obtained from the tests conducted on the sound tubes, and Figure 12B The chart illustrates these data, which are included in this application and measured at a distance of one meter. Initially, measurements were taken using a Samsung S10+ smartphone at full volume and without any type of amplification to obtain reference data and determine the amplification achieved through this application. Measurements were then taken using the same phone connected to… Figures 7C to 7H The sound tube design is shown. Results show that for frequencies between 300Hz and 1kHz, Figure 7C and Figure 7D The average gain of the tube design shown is 18.4 dB. Figure 7E and Figure 7D The average gain of the sound tube shown is 13.2 dB, and Figure 7G and Figure 7H The design has an average gain of 15.2 dB.

[0060] Figure 13A and Figure 13B Side and front isometric views detailing the sealing mechanism options in the support slot of this application are shown. When a smartphone is placed in the support slot 702 of this application 700, the smartphone's speaker aligns with the sound input hole 712, forming an airtight seal to ensure no pressure loss of sound from the phone's speaker. A rotating support wall 708 is attached to the support slot 702 via a hinge mechanism 703, pressing the phone against the support back 705 when lifted. The rotating support wall 708 is secured by a locking pin system, or vertically held by a spring or by some type of hinge that maintains the position of the rotating support wall. Figure 14B The support groove 702, the rotating support wall 708, and the support back 705 are shown to have coatings 706, 710, and 714 of an elastic material, which may be foam, silicone, rubber, or another similar material, conforming to the shape of the telephone and hermetically sealing the surface around the speaker to maintain the pressure of the sound emitted by the telephone speaker and guide the sound through the sound inlet 712 of this application into the sound tube.

[0061] Figure 14A and Figure 14B A locking system is shown on the support base 810 of this application 800. Figure 14A A locking system is shown that ensures the smartphone 815 remains securely positioned when mounted on the support base 810 of this application 800, maintaining a sufficient seal between the speaker of the smartphone 815 and the input port of the sound tube 805 included in this application. This system has a locking lever 825 located on the inner front 830 of the support base 810, which rotates about an axis 835, allowing the locking lever to be inserted into the support base 810. The system has a spring 840 that causes the locking lever 825 to return to its initial extended position outside the support base 810. The smartphone 815 must be inserted diagonally into the support base 810 so that its front portion 845 contacts the front portion 850 of the locking lever 825, then the smartphone 815 is pushed so that its rear portion 855 rests on the unfolded cover 860 and subsequently the smartphone is pressed down to position it in its final position. Figure 14BThe illustration shows how a smartphone 815 is supported by a locking lever 825, wherein a spring 840 ensures that the locking lever 825 is subjected to sufficient pressure to keep the locking lever in place and to provide a sufficient seal to prevent sound leakage between the smartphone's speaker and the audio input 805 of this application 800.

[0062] Figure 15A and Figure 15B An alternative to the locking system integrated into the support base 905 of this application 900 is shown. Figure 15A A sealing button 910 is shown located on the front 915 of a support base 905. This sealing button moves horizontally back and forth within the support base 905 and has a spring 920 that keeps the sealing button always extending outward. For mounting a smartphone 925, the smartphone is placed parallel to the angle of the unfolded charging cover 930. This mechanism allows the smartphone to be mounted from any angle and moved downwards. The lower leading edge 935 of the smartphone 930 contacts the rounded edge 940 of the sealing button 910. This button moves inwards towards the inside of the application 900. As the smartphone 925 continues to descend, the sealing button 905 is pushed out by the spring 920, applying slight pressure to the front of the smartphone 945, thereby securing and holding the smartphone in place and sealing it properly to prevent sound leakage between the phone speaker and the audio input 955 of the application 900. Figure 15B This application illustrates an alternative to the locking system for a smartphone.

[0063] Figure 16A This illustration shows an isometric view of the left front side of another embodiment of this application. Application 1000 mainly includes a base 1005, a wireless charging cap 1010, and a support flap (see [link]). Figure 16B (1015 in the middle). Inside the base 1005, electrical and electronic components that provide charging and energy storage functions are located, and it also includes the sound tube responsible for passively amplifying the volume of the mobile phone speaker in the mechanical version of this application.

[0065] Located on the left side at 1040 is, but is not limited to: a USB Type-C port 1045 for power input and battery charging (see [link]). Figure 20(and Figure 22), the connection port is also used as an output for charging other devices; one or more USB Type-A output ports 1050 or similar output ports for charging other devices; an LED indicator for the battery level of the battery 1055; an on / off button 1060 of this application; and a Bluetooth button 1065 of the electronic version of this application 1000.

[0066] The wireless charging cap 1010 includes a lower cover 1130 with a wireless charging antenna 1140 therein, a magnetic ring 1145 for attaching to a mobile phone, and a top cover 1135 for closing the wireless charging cap 1010.

[0067] Figure 16B An isometric view of the right rear side of this application 1000 is shown, illustrating the right side 1070 of the base 1005 and the mobile phone support flap 1015. A support groove 1095 for a mobile phone is provided on the upper surface 1090 of the base 1005, wherein the support groove 1095 is formed by a lower surface 1115, ... Figure 16A The right-side stop 1120 described herein is used to align and support the mobile phone with the present application 1000, and Figure 16A The preferred inclined rear portion 1125, as described in the text, is formed. A locking bar 1085 is also present in the upper portion to press the phone against... Figure 16A The rear 1125, thus holding the phone in a secure position and in different positions attached to the present application 1000. The diagonal surface 1165 is the position where the back of the present application rests when placed in an inclined position (see [reference]). Figure 18 (1247 in the text). The wireless charging cap 1010 rotates on the base 1005 along the rotation axis 1100. The mobile phone support flip plate 1015 includes... Figure 19B The U-shaped groove 1080 is described more broadly in the middle.

[0068] Figure 17A A left rear isometric view of this application 1180 with the wireless charging cap 1185 deployed is shown. The wireless charging cap 1185 is rotated about axis 1190 to an angle between 0 and 90 degrees relative to the top 1195 of this application 1180, preferably 65 degrees, thereby allowing the wireless charging cap 1185 to remain magnetically or mechanically attached to a mobile phone to provide wireless charging. In this view, the support flap 1200 is folded and can extend at a 90-degree angle together with the mobile phone support base 1205, forming a monolithic piece that rotates about a rotation axis 1225. The back cover 1210 of the wireless charging cap 1185 includes a recess 1215 that allows the support flap 1200 to be manually peeled off from the wireless charging cap 1185.

[0069] Figure 17BThis illustrates how the support flap 1200 rotates about axis 1225 and unfolds approximately 90 degrees with reference to the wireless charging cap 1185 until the protrusion 1230 of the support flap 1200 engages. Figure 17A The protrusion 1230 is located within the cavity 1235 shown in the diagram. When the support flap 1200 is folded onto the wireless charging cap 1185, the protrusion 1230 engages with the cavity 1240 of the wireless charging cap 1185 of this application 1180.

[0070] The support flap 1200 includes a metal plate or magnetic plate 1220, which is attracted to the wireless charging cap 1185 and included therein. Figure 16A The magnetic ring 1145 is seen in the image. Inside the top cover 1195 is another metal piece that is attracted to the magnetic ring 1145 of the wireless charging cap 1185, and when the two pieces are close together, the magnetic attraction will keep the application in the closed position.

[0071] Figure 18 A rear isometric view of the present application 1250 in a horizontal position is shown, wherein the wireless charging cap 1255 is unfolded approximately 65 degrees relative to the top cover 1260 of the present application 1250. In the horizontal position of the present application 1250, the support flap 1265 remains folded to the wireless charging cap 1255, and the mobile phone support base 1270 provides a support surface and provides stability to the present application 1250 in the stated position.

[0072] Figure 19A A front isometric view of the present application 1280 in an inclined position is shown. This view shows a wireless charging cap 1285 deployed at approximately 65° relative to the top cover 1290 of the present application 1280, and a support flap 1295 deployed at approximately 180° relative to the wireless charging cap 1285.

[0073] Figure 19B Details of a mobile phone support base 1300 are shown, the mobile phone support base including Figure 19A The U-shaped groove 1310, formed by two diagonal surfaces 1312 and a horizontal surface 1315, creates a hollow space that prevents the side buttons 1316 of the mobile phone from being pressed when the mobile phone 1318 is placed on the mobile phone support base 1300.

[0074] Figure 20A top view of an embodiment of the internal layout of the electronic and mechanical components of this application 1320 is shown. This version includes, but is not limited to: two rechargeable cylindrical lithium batteries 1325 or the like, each with a capacity between 1000mAh and 20000mAh, preferably 5000mAh each, connected to a power management PCB 1330 for controlling battery charging and discharging; a wireless charging antenna; one or more USB-C power input / output ports 1335 or the like; one or more USB-A power output ports 1340 or the like; and a charging indicator LED for the rechargeable battery 1345. A power button 1350 enables the wireless charging feature of this application 1320. This and other versions of this application may include, but are not limited to, other types of ports, such as ports for data transmission. A partial view of a passive sound amplifier tube 1355 is shown.

[0075] Figure 21 This application 1370 shows Figure 20 The version includes a top view of the passive sound amplifier tube 1375. The sound amplifier tube 1375 has an inlet for sound from a smartphone speaker 1380, an inlet for a mobile phone microphone 1385, and an outlet for the sound tube 1390 of this application 1370. The sound tube 1375 is composed of sidewalls 1410 forming the path and height of the sound tube. The height of the sound tube begins between 3 mm and 5 mm, preferably 4 mm, and ends between 15 mm and 20 mm, preferably 17.5 mm. The initial width A of the sound tube 1415 begins between 12 mm and 20 mm, preferably 16 mm, and the sound tube increases in both length and height until it reaches a final width B between 35 mm and 50 mm, preferably 40 mm, before reaching the outlet C of the sound tube 1390, where the sound tube widens from 50 mm to 80 mm, preferably 68 mm. The length E of holes 1380 and 1385 is between 3 mm and 6 mm, preferably 4 mm, and the width is D.

[0076] The two lower sidewalls 1410 of the sound tube 1375 can form part of the lower cover 1395 of this application 1370. The upper cover 1415 of the sound tube 1375 is mounted on the lower sidewalls 1410 and secured by retaining pins 1400. Sealing the sound tube 1375 is crucial for maintaining the internal pressure and increasing the decibel gain of the sound; therefore, a sealing adhesive or (but not limited to) glue 1405 can be added between the sound tube cover 1415 and the sound tube sidewalls 1410.

[0077] The sound tube 1375 redirects the sound emitted by the smartphone speaker to the sound tube output port 1390, and in preliminary tests of sound level applications, passively increases the volume gain of the mobile phone by 5 to 15 dB in frequencies from 200 Hz to 20,000 Hz.

[0078] Figure 22A A top view showing the internal layout of the electronic and mechanical components of this application 1420 is provided, using an electric speaker 1440 instead of a passive sound tube. This version includes, but is not limited to, two rechargeable cylindrical batteries 1425 connected to a power management PCB 1430, which in turn connects to a Bluetooth—or similar—PCB 1435 for wireless sound management. The Bluetooth PCB 1435 includes an antenna and all the electronics that allow it to be detected and paired with other devices (such as mobile phones, tablets, etc.) and emits sound through a sound output opening 1445 of this application 1420. Embedded software programming included on PCBs 1430 and 1435 enables Bluetooth pairing of this application 1420 and controls signals transmitted to one or more of the front speakers 1440, which output sound through the sound output opening 1445 of this application 1420.

[0079] Figure 22B An option for an electronic version of the sound diverter 1422 of this application 1420 is shown. The sound diverter 1422 is located in the front region of the application, immediately following the front grille 1450 and in a fixed position behind the grille, above the electric speaker 1440. Sound 1447 from the mobile phone speaker enters through the first port 1448 of the sound diverter 1422 and passes through a short J-tube, directing the wave towards the front of the application 1420 through the second port 1452. Sound 1446 entering through the third port 1456 of the sound diverter 1422 enters the mobile phone microphone through the fourth port 1442. A microphone-based mobile phone echo cancellation function will allow the cancellation of noise received from the same mobile phone speaker.

[0080] Figure 23A This is a cutaway top view of the front side of application 1460, showing details of the displacement of the locking bar 1465 that secures the phone in the retaining groove 1475. The locking bar 1465 has springs 1470 that keep the locking bar protruding outward by maintaining a distance A from the rear support 1480 of the support groove 1475.

[0081] Figure 23BThe description describes inserting a mobile phone into a support slot 1475, whereby a spring 1470 is pressed against the rear wall 1490 of a cavity 1495, forcing a locking bar 1465 to move back a distance B. The locking bar 1465 presses the mobile phone against the rear support 1480 of the support slot 1475 and helps hold the mobile phone in place, with no difference in the placement of the 1460. When the mobile phone is removed from the support slot 1475, the spring 1470 returns the locking bar 1465 to its unpressed position A. The locking bar 1465 can also be moved by manually pulling forward with a finger on a protrusion 1455 that is part of the locking bar 1465.

[0082] Figure 24A and Figure 24B The images show the application in the closed position and the vertical position, respectively. Figure 24A A smartphone 1505 is shown positioned on top of this application 1500. When the power button 1510 is pressed, the wireless charging function of this application is activated. Mobile phones and other devices can also be wired charged using, but are not limited to, the USB-C and USB-A charging ports included in this application 1500. Pressing the Bluetooth button 1515 activates this function of this application 1500, allowing the smartphone 1505 or any other device not physically connected to this application to pair and emit its sound 1520 through the front grille 1525, redirecting the sound towards the front of this application 1500.
