[0016] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0017] This application provides an electronic device. Figures 1-4 The electronic device 100 may include a housing 10 and a knob assembly 20. For example, the electronic device 100 may be a walkie-talkie, a mobile phone, or a tablet computer. The housing 10 forms a protective barrier for the internal components, protecting them from, for example, dust or moisture. The housing 10 may be made of plastic, rubber, an organic polymer, or metal. The housing 10 may be a split-body structure, for example, consisting of multiple relatively independent sub-housings that are individually machined and then assembled and connected; or it may be a one-piece structure, for example, formed integrally by injection molding. The housing 10 may be generally rectangular in shape. The housing 10 has a front face 13 and a top face 14 adjacent to the front face 13. The front face 13 is the side facing the user's line of sight during use. If the electronic device 100 has a display screen, the front face 13 may be the side on which the display screen is located. Accordingly, the top face 14 is the side above the user's line of sight during use. The housing 10 is provided with a first opening 11 on the top surface 14 . The housing 10 is provided with a receiving cavity 12 in communication with the first opening 11 . The receiving cavity 12 can accommodate components of the electronic device 100 .

[0018] The knob assembly 20 is used to change a target control parameter of the electronic device 100. For example, the target control parameter can be one of a channel parameter, a speaker volume parameter, or a screen brightness parameter. Accordingly, by changing the target control parameter through the knob assembly 20, the channel, speaker volume, or screen brightness of the electronic device 100 can be adjusted. The knob assembly 20 includes an operating member 21 and a functional member 22. The functional member 22 is fixed within the accommodating cavity 12. The operating member 21 can be rod-shaped. One end of the operating member 21 is movably connected to the functional member 22, and the other end of the operating member 21 is inserted into the first opening 11. The connection between the operating member 21 and the functional member 22 can be a rotational or sliding connection, so that the relative movement between the operating member 21 and the functional member 22 generates a corresponding electrical signal, which can be used to change the target control parameter. The functional member 22 is configured to change the target control parameter of the electronic device 100 in response to external operation of the operating member 21. The external operation can be an operation such as applying torque, pressure, or tension to the operating member 21. The target control parameter of the electronic device 100 has multiple preset representative values. When the electronic device 100 is a walkie-talkie, the target control parameter may be a channel parameter, and the representative value may be a channel code. The channel parameter has multiple preset channel codes for user selection. By selectively adjusting the channel code of the electronic device 100 to one of the channel codes using the knob assembly 20, the electronic device 100 can communicate with other electronic devices 100 with the same channel code. When the target control parameter is a speaker volume parameter, the representative value may be a volume level code. The level code corresponds to the volume level, making it easy to identify the volume level through the level code.

[0019] The electronic device 100 is configured to display a representative value corresponding to the current value of the target control parameter when the knob assembly 20 changes the target control parameter of the electronic device 100. In one embodiment, the representative value corresponding to the current value of the target control parameter can be displayed on the display screen of the electronic device 100 so that the user can promptly know the current value of the target control parameter, thereby achieving visual adjustment of the target control parameter.

[0020] See also Figure 3 、 Figure 5 In one embodiment, the electronic device 100 is provided with a marker 23 representing a value, and the marker 23 can be used to display the representative value corresponding to the current value of the target control parameter. For example, the marker 23 can be in the form of Arabic numerals, Roman numerals, English letters, or other characters, or it can be in the form of an easily recognizable pattern. The marker 23 can be formed on the corresponding carrier by a process such as silk screen printing, spraying, or etching. Figure 3 、 Figure 5As shown, markers 23 representing the values are provided around the circumference of the operating member 21. The operating member 21 is configured to move relative to the functional member 22 under external operation and drive the markers 23 to move, so that when the target control parameter is changed, one of the markers 23 corresponding to the current value of the target control parameter is displayed on the side facing the front face 13. This arrangement allows the markers to be displayed on the side facing the front face 13 so that they are in the user's line of sight, making them easier for the user to observe and allowing the user to quickly learn the current value of the target control parameter.

[0021] In one embodiment, the electronic device 100 is a walkie-talkie, the target control parameter is a channel parameter, and the representative value is a channel code. For example, the representative value is a channel code 1, 2, 3, etc., representing different communication frequencies. The mark 23 is an Arabic numeral 1, 2, 3, etc. silk-screened on the corresponding carrier. When the channel parameter changes to "2", one of the indicators 23 corresponding to the current value of the target control parameter (Arabic numeral "2") is displayed on the side facing the front surface 13.

[0022] The mark 23 can be arranged outside the accommodating cavity 12 so that the mark 23 is exposed to the housing 10 and the housing 10 does not block the mark 23, thereby facilitating the user to view the indicator mark.

[0023] See also Figure 1 、 Figure 3 In one embodiment, the indicator 23 is disposed within the accommodating cavity 12 , and the front face 13 of the housing 10 is provided with a light-transmitting area 15 , through which the indicator is visible. Placing the indicator 23 within the accommodating cavity 12 , on the one hand, provides the housing 10 with a protective barrier for the indicator 23 , making it less susceptible to damage and thus extending the service life of the indicator 23 ; on the other hand, when a user operates the operating member 21 , the housing 10 prevents the user from accessing the indicator 23 , thus preventing the indicator 23 from being obscured. This makes the indicator easier to observe, allowing the user to quickly obtain the current value of the target control parameter.

[0024] The mark 23 can be processed on a self-luminous material so that the indicator mark can be clearly observed even in a dark environment. Figure 3As shown, the electronic device 100 includes a light-emitting component 30. The light-emitting component 30 can be a light-emitting diode, an infrared light source or a digital tube, etc. The light-emitting component 30 is arranged in the accommodating cavity 12, and the light emitted by the light-emitting component 30 is configured to illuminate the area where the indicator mark is located to increase the display brightness of the indicator mark. The light emitted by the light-emitting component 30 can be directly illuminated to the area where the indicator mark is located. For example, the light-emitting component 30 is arranged around the periphery of the light-transmitting area 15, and the light emitted by the light-emitting component 30 can illuminate the side of the area where the indicator mark is located facing the front end face 13 to increase the display brightness of the indicator mark; for another example, the light-emitting component 30 is arranged on the side of the area where the indicator mark is located away from the front end face 13, the mark 23 is translucent, and the light emitted by the light-emitting component 30 can be transmitted through the indicator mark and the light-transmitting area 15 to increase the display brightness of the indicator mark. The light emitted by the light-emitting component 30 can also be indirectly illuminated to the area where the indicator mark is located. For example, the light-emitting element 30 is integrated onto a circuit board within the electronic device 100. The electronic device 100 is also provided with a light guide (not shown). The light guide may be made of a material such as organic glass, polycarbonate, acrylic resin, or epoxy resin. The light emitted by the light-emitting element 30 is guided by the light guide to indirectly illuminate the area where the indicator mark is located, thereby increasing the display brightness of the indicator mark. The light emitted by the light-emitting element 30 is arranged to illuminate the area where the indicator mark is located, so that the indicator mark can be clearly observed even in a dimly lit environment, expanding the application scenarios of the electronic device 100.

[0025] The housing 10 may be made of an opaque material or a translucent material. Translucent means that the transmittance is between 60% and 70%, which can shield the components housed in the housing 10, prevent the components from being directly exposed to the user's field of view, and enhance the appearance of the electronic device 100. In one embodiment, the housing 10 is provided with a translucent sheet (not shown in the figure), through which light can pass, and the area where the translucent sheet is located forms a translucent area 15. The translucent sheet may be made of a transparent material with a transmittance greater than or equal to 90%. The translucent sheet may be integrally injection molded with the surrounding area of the translucent sheet, or they may be processed separately and then assembled and connected.

[0026] In one embodiment, if Figure 3 As shown, the front face 13 of the housing 10 is provided with a second opening 16, which forms a light-transmitting area 15 through which the indicator mark is visible. The second opening 16 can be a through-hole or a notch. By providing the second opening 16 on the front face 13 of the housing 10 to form the light-transmitting area 15, the housing 10 does not need to use a different material in the light-transmitting area 15 than in the surrounding area of the light-transmitting area 15, thereby reducing the number of material types for the housing 10, reducing the processing difficulty of the housing 10, and lowering production costs.

[0027] In one embodiment, if Figure 5As shown, the carrier of the mark 23 can be the operating member 21. For example, the mark 23 is processed on the outer wall surface of the operating member 21 by using a process such as silk screen printing, spraying or etching. Figure 3 、 Figure 6 As shown, the knob assembly 20 includes a knob cap 24, which is connected to the end of the operating member 21 away from the functional member 22. The knob cap 24 is configured to carry the logo 23. The knob cap 24 includes a top wall 241 and a first cylindrical side wall 242 connected to the top wall 241. The first cylindrical side wall 242 is sleeved outside the operating member 21. The logo 23 is disposed on the outer wall of the first cylindrical side wall 242, and the projection of the indicator logo along the direction perpendicular to the front end surface 13 falls within the range of the light-transmitting area 15. The logo 23 is disposed on the outer wall of the first cylindrical side wall 242. Since the first cylindrical side wall 242 is sleeved outside the operating member 21, the outer wall of the first cylindrical side wall 242 has a larger surface area than the outer wall of the operating member 21, thereby accommodating the larger logo 23, making the indicator logo easier for the user to clearly observe.

[0028] The connection between the knob cap 24 and the operating member 21 can be adhesive or snap-fit, so that the knob cap 24 is not easy to fall off. In one embodiment, the knob cap 24 is snap-fitted to the operating member 21, which can facilitate the removal or installation of the knob cap 24 when the electronic device 100 is repaired. Figure 3 As shown, the operating member 21 is connected to the end of the first cylindrical side wall 242 near the top wall 241 by an interference fit, and the mark 23 is provided at the other end of the first cylindrical side wall 242 away from the top wall 241. A gap is provided between the inner wall of the other end of the first cylindrical side wall 242 and the outer wall of the operating member 21. The gap provided between the inner wall of the end of the first cylindrical side wall 242 away from the top wall 241 and the outer wall of the operating member 21 reduces the connection length between the first cylindrical side wall 242 and the operating member 21. A "flare" is formed at the end of the first cylindrical side wall 242 near the insertion direction of the operating member 21, which can reduce the resistance of the operating member 21 to the knob cap 24 during assembly, thereby facilitating the assembly of the knob cap 24.

[0029] See also Figure 3 In one embodiment, along the extension direction of the operating member 21, the wall thickness of the first cylindrical side wall 242 at the end closest to the top wall 241 is greater than the wall thickness of the end of the first cylindrical side wall 242 farther from the top wall 241. The thicker wall thickness of the end of the first cylindrical side wall 242 connected to the operating member 21 provides greater strength at the end where the first cylindrical side wall 242 is connected to the operating member 21, making it less susceptible to failure under external forces and enhancing the reliability of the connection between the knob cap 24 and the operating member 21.

[0030] The operating member 21 can be directly inserted into the first cylindrical side wall 242. For example, in the direction perpendicular to the extension of the operating member 21, the cross-sectional dimension of the inner space of the first cylindrical side wall 242 is smaller than the cross-sectional dimension of the operating member 21, so that the operating member 21 is connected to the first cylindrical side wall 242 by interference fit. Figure 2 、 Figure 3 As shown, the knob assembly 20 includes a bushing 25, through which the operating member 21 is connected to the first cylindrical sidewall 242. The bushing 25 is accommodated in the first cylindrical sidewall 242 and is sleeved on the operating member 21 so that the operating member 21 is connected to the first cylindrical sidewall 242 through an interference fit. The bushing 25 is generally cylindrical in shape, with a notch formed along the longitudinal direction of the cylinder. The bushing 25 is not closed in the circumferential direction, which makes the bushing 25 elastic, thereby facilitating the bushing 25 to be assembled into the first cylindrical sidewall 242. The bushing 25 can be made of an elastic metal sheet, or it can be made of rubber or other polymer materials.

[0031] See also Figure 3 In one embodiment, the knob cap 24 includes a second cylindrical sidewall 243 connected to the top wall 241. The second cylindrical sidewall 243 surrounds the first cylindrical sidewall 242. A user can grasp the second cylindrical sidewall 243 when operating the operating member 21. Because the second cylindrical sidewall 243 surrounds the first cylindrical sidewall 242, the second cylindrical sidewall 243 has a larger dimension relative to the first cylindrical sidewall 242 and the operating member 21 in a direction perpendicular to the extension of the operating member 21. This provides a larger lever arm when rotating the operating member 21, making the rotation of the operating member 21 more labor-efficient and facilitating user operation of the operating member 21. The housing 10 is provided with a third cylindrical sidewall 17 at the first opening 11. The first cylindrical sidewall 242 is accommodated within the third cylindrical sidewall 17. One end of the third cylindrical sidewall 17 protrudes outward from the accommodating chamber 12 and is accommodated in the internal space between the second cylindrical sidewall 243 and the first cylindrical sidewall 242. One end of the third cylindrical side wall 17 is accommodated in the inner space between the second cylindrical side wall 243 and the first cylindrical side wall 242. When external dust or water vapor enters the shell 10, it needs to bypass the end of the third cylindrical side wall 17 protruding outside the accommodating cavity 12, which increases the length of the dust or water vapor movement path and increases the flow resistance, making it difficult for dust or water vapor to enter the interior of the electronic device 100, thereby improving the waterproof and dustproof performance of the electronic device 100.

[0032] In one embodiment, if Figure 3As shown, the other end of the third cylindrical side wall 17 protrudes into the accommodating cavity 12, and the housing 10 is provided with an annular protrusion 18, which is connected to the third cylindrical side wall 17. The annular protrusion 18 is used to fix the functional component 22. The functional component 22 includes a main body 28 and a connecting portion 29 that are connected to each other. The main body 28 is connected to the operating component 21 through the connecting portion 29. The connecting portion 29 is provided with a hole (not shown in the figure), and the operating component 21 is inserted into the hole and movably connected to the main body 28. The knob assembly 20 includes a fixing member 26, which is connected to the connecting portion 29. The lower side of the annular protrusion 18 abuts against the main body 28, and the upper side of the annular protrusion 18 abuts against the fixing member 26, so as to fix the functional component 22 in the accommodating cavity 12. The abutment can be a direct abutment where two components contact each other, or an indirect abutment where the two components contact through other components. The fixing member 26 may be a nut, and the connecting portion 29 is provided with threads, and the fixing member 26 is threadedly connected to the connecting portion 29, thereby fixing the functional component 22 in the accommodating cavity 12. The fixing member 26 may also be glue, double-sided tape, or other sticky materials, that is, the functional component 22 can be fixed in the accommodating cavity 12 by glue, double-sided tape, or other sticky materials.

[0033] When the second opening 16 is provided on the front surface 13 of the housing 10 to form the light-transmitting area 15, external dust or water vapor may enter the housing 10 through the second opening 16. Figure 2 、 Figure 3 In one embodiment, the knob assembly 20 further includes a seal 27 disposed between the annular protrusion 18 and the main body 28. The lower side of the annular protrusion 18 abuts against the main body 28 via the seal 27. The seal 27 can be made of an elastic material such as silicone, rubber, or foam. When the seal 27 is assembled between the annular protrusion 18 and the main body 28, the seal 27 elastically deforms, thereby sealing the gap between the annular protrusion 18 and the main body 28, thereby improving the waterproof and dustproof performance of the electronic device 100.

[0034] See also Figure 7In one embodiment, electronic device 100 may include an RF circuit 91, a memory 92, an input unit 93, a display unit 94, a sensor 95, an audio circuit 96, a wireless communication module 97, a processor 98, and a power supply 99. The RF circuit 91, memory 92, input unit 93, display unit 94, sensor 95, audio circuit 96, and wireless communication module 97 are each connected to the processor 98; the power supply 99 is used to provide power to the electronic device 100.
