TECHNICAL FIELD

[0001] The present application relates to the technical field of terminal, in particular to an electronic device. BACKGROUND

[0002] With the development of mobile Internet and the popularity of smart mobile terminals, the user group of smart mobile terminals is getting larger and larger, and more intelligent and humanized requirements are put forward for terminal devices. Therefore, a mobile terminal capable of releasing fragrance emerges as the times require.

[0003] However, the current terminal device usually has a hole in the device shell for fragrance emission, and the appearance integrity of the device is good, and the hole is easy to introduce dust and water vapor. CONTENT OF THE UTILITY MODEL

[0004] The present application provides an electronic device. The electronic device can emit fragrance, and the appearance integrity of the electronic device is good.

[0005] The present application provides an electronic device. The electronic device includes a shell, a loudspeaker and a fragrance card, the shell encloses a first space, the shell is provided with a first sound hole, the first sound hole communicates the first space with the outside of the shell, the loudspeaker is installed in the first space, and the first sound hole is used for making the sound emitted by the loudspeaker propagate to the outside of the shell; the fragrance card is detachably connected in the first space, the first space is provided with an air passage, the air passage communicates with the first sound hole, and the air passage is used for making the fragrance generated by the fragrance card propagate to the first sound hole, and the first sound hole is used for making the fragrance in the air passage propagate to the outside of the shell.

[0006] In the present application, the electronic device has a fragrance emitting function. When the fragrance card is installed in the shell, the fragrance card can generate fragrance. The fragrance generated by the fragrance card can be propagated to the first sound hole of the shell through the air passage, and then propagated to the outside of the shell through the first sound hole, so as to realize the fragrance emitting function of the electronic device. It can be understood that the fragrance emitted by the electronic device is a gas with a specific fragrance, which can have a specific function (such as helping sleep or refreshing, etc.), thereby improving the user's experience.

[0007] The first sound hole has the effect of "one thing with multiple uses". On the one hand, the first sound hole can be used as a sound outlet channel of the loudspeaker. The sound emitted by the loudspeaker can enter the first sound hole and propagate to the outside of the shell, thereby realizing the audio playing function of the electronic device. On the other hand, the fragrance generated by the fragrance card can also propagate to the outside of the shell through the first sound hole. In this way, the shell of the electronic device does not need to be additionally provided with a through hole for emitting fragrance, so that the shell of the electronic device has fewer openings, the appearance integrity of the electronic device is better, and dust and water vapor are not easily introduced.

[0008] In some embodiments, the speaker is provided with a second sound outlet and an air inlet hole. The second sound outlet is in communication with the internal space of the speaker and the first sound outlet, and is used for transmitting the sound emitted by the speaker to the first sound outlet. The air inlet hole is in communication with the internal space of the speaker and the air passage, and is used for transmitting the fragrance generated by the fragrance card to the second sound outlet.

[0009] In the present embodiment, the fragrance generated by the fragrance card can enter the internal space of the speaker through the air inlet hole of the speaker, and then be transmitted to the first sound outlet of the housing from the second sound outlet of the speaker. It can be understood that the internal space of the speaker can serve as a channel for the fragrance to propagate.

[0010] In some embodiments, the speaker includes a first side and a second side arranged oppositely. The first side faces the first sound outlet, and the second sound outlet penetrates the first side. The speaker further includes a third side and a fourth side arranged oppositely. The third side and the fourth side are connected between the first side and the second side. The air inlet hole penetrates at least one of the second side, the third side, and the fourth side.

[0011] In the present embodiment, the second sound outlet is arranged on the first side, and the first side faces the first sound outlet, so as to facilitate the communication between the second sound outlet and the first sound outlet. In addition, the air inlet hole and the second sound outlet are arranged in different directions, so as to facilitate the communication between the air inlet hole and the air passage, thereby facilitating the transmission of the fragrance generated by the fragrance card to the internal space of the speaker through the air inlet hole.

[0012] In some embodiments, the electronic device includes a first state and a second state. In the first state, the frequency of the sound generated by the speaker is in the range of 20 Hz to 20,000 Hz. In the second state, the frequency of the sound generated by the speaker is in the range of 20 Hz to 25,000 Hz. When the fragrance card is in a non-working state, the electronic device is in the first state. When the fragrance card is in a working state, the electronic device is in the second state.

[0013] It can be understood that, in the present embodiment, when the electronic device is in the first state, the speaker can be used to play the audio of the electronic device to be received by the user, thereby realizing the audio playing function of the electronic device. When the electronic device is in the second state, the speaker can be used to play the audio of the electronic device, and can also be used to generate ultrasonic waves with a frequency higher than 20,000 Hz.

[0014] It can be understood that the ultrasonic wave has a high vibration frequency and a large energy. The ultrasonic wave can make the vibration frequency of the gas molecules in the air the same as the frequency of the ultrasonic wave, so as to increase the vibration frequency of the gas molecules, thereby increasing the vibration speed of the gas molecules, and further increasing the propagation rate of the gas molecules. In the embodiment, the ultrasonic wave generated by the loudspeaker can increase the propagation speed of the aroma in the loudspeaker, so that the aroma can be propagated to the first sound hole and then to the outside of the shell more quickly. In this way, the electronic device can have a better aroma diffusion effect.

[0015] In addition, since the frequency of the ultrasonic wave is higher than the perception range of the human ear and is an inaudible sound wave for the human ear, the loudspeaker can generate the ultrasonic wave while realizing the audio playing function of the electronic device. At this time, the ultrasonic wave does not affect the reception of the audio signal by the user, that is, does not affect the experience of the user on the audio playing function of the electronic device.

[0016] In some embodiments, the electronic device further comprises a card seat and a card holder. The card seat is installed in the first space, and the internal space of the card seat is communicated with the air passage. The card holder is detachably inserted into the internal space of the card seat. When the fragrance card is installed in the shell, the fragrance card is accommodated in the card holder.

[0017] It can be understood that the fragrance card needs to be replaced as a consumable product. In the embodiment, the card holder is provided for placing the fragrance card, and the fragrance card is inserted into the card seat through the card holder. This can realize the connection of the fragrance card and the shell and facilitate the replacement of the fragrance card.

[0018] In some embodiments, the card seat is provided with a hollow region, and the hollow region communicates the internal space of the card seat with the air passage. In this way, the gas flow channel between the internal space of the card seat and the first space of the shell can be increased, and the propagation of the gas between the internal space of the card seat and the first space of the shell can be further accelerated.

[0019] In some embodiments, the shell comprises a middle frame, a rear cover, and a partition plate. The rear cover is fixed to the middle frame and cooperates with the middle frame to enclose the internal space of the shell. The partition plate connects the rear cover and the middle frame, and the partition plate divides the internal space of the shell into the first space. The loudspeaker, the card seat, the rear cover, and the partition plate jointly enclose the air passage.

[0020] In the embodiment, the internal space of the shell is divided into the first space by the partition plate, and the loudspeaker and the card seat are both installed in the first space. In this way, the air passage can be relatively short, and the propagation path of the aroma generated by the fragrance card can be relatively short, which is beneficial to increasing the propagation rate of the aroma and thus improving the aroma diffusion effect of the electronic device.

[0021] In addition, the electronic device can use the internal components of the electronic device to enclose the air passage, without the need to provide an additional channel to form the air passage. In this way, the structure of the electronic device is relatively simple, and the cost is relatively low.

[0022] In some embodiments, the card slot is provided with a first card slot and a second card slot, when the fragrance card is installed in the shell, the fragrance card is located in the first card slot; when the SIM card of the electronic device is installed in the shell, the SIM card of the electronic device is located in the second card slot.

[0023] In the embodiment, the fragrance card and the SIM card can share one card slot, which is beneficial to simplify the components and structure of the electronic device.

[0024] In some embodiments, the shape and size of the first card slot are the same as those of the second card slot.

[0025] In the embodiment, the fragrance card and the SIM card can use the first card slot and the second card slot. At this time, the first card slot and the second card slot can have the same structure design, so that the manufacturing process of the card slot can be simplified. In addition, when the user inserts the fragrance card or the SIM card, it is not necessary to identify the corresponding card slot of the fragrance card or the SIM card, so that the assembly process of the fragrance card and the SIM card can be simplified, and the user experience can be improved.

[0026] In some embodiments, the fragrance card comprises a fragrance part, an encapsulation part and a heating part, the fragrance part has a fragrance, the encapsulation part covers the fragrance of the fragrance part, the heating part is located on the side of the fragrance part away from the encapsulation part and is connected to the fragrance part, and the heating part is used for heating the fragrance part.

[0027] In the embodiment, the fragrance card can heat the fragrance part by using the heating part to excite the fragrance of the fragrance part, so that the fragrance card emits fragrance. It can be understood that in the embodiment, the fragrance card can release fragrance by heating.

[0029] In the embodiment, the power supply of the electronic device can supply power to the heating element through the first electrical connecting element and the second electrical connecting element to make the heating element generate heat.

[0030] In some embodiments, the heating element comprises a metal sheet, a resistance wire or a coil. In this way, the cost of the heating element is low. It can be understood that after the heating element is electrified, the electrical energy can be converted into internal energy, so that the fragrance part of the fragrance card can be heated.

[0031] In some embodiments, the electronic device further comprises a temperature sensor, the temperature sensor is arranged in the first space, and the temperature sensor is configured to detect the temperature of the fragrance card; the electronic device further comprises a controller, the controller is arranged in the internal space of the shell, and the controller is electrically connected to the heating unit and the temperature sensor, and the controller is configured to control the heating temperature of the heating unit according to the detection value of the temperature sensor.

[0032] It can be understood that, in the present embodiment, the temperature sensor can be used to detect whether the temperature of the fragrance card reaches a predetermined range, i.e., whether the activation temperature of the fragrance of the fragrance card is reached. If the detection value of the temperature sensor is lower than the predetermined range, the controller controls the heating temperature of the heating member to increase. If the detection value of the temperature sensor is higher than the predetermined range, the controller controls the heating temperature of the heating member to decrease. If the detection value of the temperature sensor is within the predetermined range, the controller controls the heating temperature of the heating member to maintain within the predetermined range. It can be understood that the activation temperature of the fragrance of the fragrance card is within the predetermined range.

[0033] In some embodiments, the electronic device further comprises a heating assembly, the heating assembly is arranged in the first space, and the heating assembly is configured to heat the fragrance card. In this way, the electronic device can heat the fragrance card by using the heating unit to activate the fragrance of the fragrance card, so that the fragrance card emits fragrance. By arranging the heating assembly in the first space, the heating assembly does not need to be replaced when the fragrance card is replaced, which is beneficial to save costs.

It can be understood that in the embodiments of the present application, the interior space of the loudspeaker 30 can serve as a channel for the aroma propagation. Please refer to Figure 3B and Figure 4 , Figure 4 is Figure 2 a partial structure schematic diagram of the electronic device 100 in some embodiments. Exemplarily, Figure 4 The card holder 50 of the electronic device 100 shown in

[0090] In some embodiments, the loudspeaker 30 and the card holder 40 can be both mounted on the first space 101 of the shell 10. The first space 101 can be provided with an air channel 1011. Exemplarily, the rear cover 12, the partition plate 13, the card holder 40 and the loudspeaker 30 of the shell 10 can jointly enclose the air channel 1011. It can be understood that the air channel 1011 is a part of the first space 101, and at least part of the air channel 1011 is located between the card holder 40 and the loudspeaker 30. It can be understood that the gaps between the internal components, between the structural components, and between the internal components and the structural components of the electronic device 100 can all serve as the air channel 1011. In the embodiments of the present application, the electronic device 100 can enclose the air channel 1011 by using the internal components of the electronic device, so that no additional channel needs to be provided to form the air channel 1011. In this way, the structure of the electronic device 100 is relatively simple and the cost is relatively low.

[0091] For example, the speaker 30 can be fixedly connected to the rear cover 12 of the shell 10. A first side surface 311 of the speaker 30 faces the first sound outlet 14 of the shell 10 and is connected to the shell 10. At this time, a second sound outlet 315 of the speaker 30 can be communicated with the first sound outlet 14. The speaker 30 is configured to convert an electrical signal into a sound signal, and the sound signal can be transmitted to the outside of the electronic device 100 through the first sound outlet 14 of the shell 10 to achieve sound playing. It can be understood that the first sound outlet 14 of the shell 10 can be configured to allow the sound emitted by the speaker 30 to be transmitted to the outside of the shell 10.

[0092] For example, the air inlet hole 316 of the speaker 30 can be communicated with the air passage 1011 of the shell 10. The air passage 1011 can be communicated with the internal space of the speaker 30 through the air inlet hole 316 of the speaker 30, thereby being communicated with the second sound outlet 315 of the speaker 30 and the first sound outlet 14 of the electronic device 100. In this way, the gas in the air passage 1011 can enter the internal space of the speaker 30 through the air inlet hole 316, and then be emitted to the outside of the shell 10 through the second sound outlet 315 of the speaker 30 and the first sound outlet 14 of the electronic device 100.

[0093] In the embodiment of the present application, the second sound outlet 315 of the speaker 30 is arranged on the first side surface 311, so as to facilitate the second sound outlet 315 to be opposite to and communicated with the first sound outlet 14. In addition, the air inlet hole 316 of the speaker 30 is arranged on at least one of the second side surface 312, the third side surface 313 and the fourth side surface 314, so that the air inlet hole 316 is different from the second sound outlet 315 in the direction, and the air inlet hole 316 is communicated with the air passage 1011, thereby facilitating the fragrance generated by the fragrance card 60 to be transmitted to the internal space of the speaker 30 through the air inlet hole 316.

[0094] In the embodiments of the present application, the electronic device 100 can include a first state and a second state. In the first state, the frequency of the sound produced by the loudspeaker 30 of the electronic device 100 is in the range of 20 Hz to 20,000 Hz. It can be understood that when the electronic device 100 is in the first state, the loudspeaker 30 can be used to play the audio of the electronic device to be received by the user, thereby realizing the audio playing function of the electronic device 100. In the second state, the frequency of the sound produced by the loudspeaker 30 of the electronic device 100 is in the range of 20 Hz to 25,000 Hz. It can be understood that when the electronic device 100 is in the second state, the loudspeaker 30 can be used to play the audio of the electronic device, and can also be used to produce ultrasonic waves with a frequency higher than 20,000 Hz. It can be understood that the vibration frequency of ultrasonic waves is high and has high energy. The ultrasonic waves can make the vibration frequency of the gas molecules in the air the same as the frequency of the ultrasonic waves, thereby increasing the vibration frequency of the gas molecules, accelerating the vibration speed of the gas molecules, and further increasing the propagation rate of the gas molecules. In addition, since the frequency of the ultrasonic waves is higher than the perception range of the human ear and is an inaudible sound wave for the human ear, the loudspeaker 30 can produce ultrasonic waves while realizing the audio playing function of the electronic device 100, and at this time the ultrasonic waves will not affect the user's reception of the audio signal, that is, will not affect the user's experience of the audio playing function of the electronic device 100.

[0095] In some other embodiments, the electronic device 100 includes a plurality of loudspeakers 30, which cooperate with each other to improve the sound quality of the electronic device 100. The number of loudspeakers 30 is not limited in the present application, and those skilled in the art can design according to actual needs.

[0096] Please refer to Figure 4 to Figure 6 , Figure 5 is Figure 2 the structural schematic diagram of the card seat 40 in some embodiments, Figure 6 is Figure 5 the partial structural schematic diagram of the card seat 40 from another angle.

[0097] In some embodiments, the card seat 40 can be installed in the first space 101 of the shell 10 and arranged apart from the loudspeaker 30. For example, the card seat 40 can be fixedly connected to the rear cover 12 of the shell 10. For example, the third side surface 313 of the loudspeaker 30 faces the card seat 40.

[0098] In some embodiments, the card seat 40 can include a cover plate 41 and a bottom plate 42. The cover plate 41 is fixedly connected to the bottom plate 42 and cooperates with the bottom plate 42 to enclose an inner space 43 of the card seat 40. For example, the cover plate 41 can be fixedly connected to the bottom plate 42 by screws, bolts or other fasteners. The bottom plate 42 of the card seat 40 can be fixedly connected to the housing 10 by adhesion or by screws or other fasteners.

[0099] It can be understood that, in the present embodiment, the inner space 43 of the card seat 40 can be an open space. The inner space 43 of the card seat 40 can be in communication with the air passage 1011 of the housing 10, so that the inner space 43 of the card seat 40 can be in communication with the air inlet 316 of the speaker 30 through the air passage 1011 of the housing 10. Gas can propagate from the inner space 43 of the card seat 40, through the air passage 1011 of the housing 10, to the inner space of the speaker 30, and then propagate to the first sound outlet 14 of the housing 10 through the second sound outlet 315 of the speaker 30.

[0100] For example, the card seat 40 can be provided with a hollow region 44. A portion of the hollow region 44 can be arranged on the cover plate 41 and in communication with the inner space 43 of the card seat 40 and the outside of the card seat 40, so that the inner space 43 of the card seat 40 can be in communication with the first space 101 of the housing 10 through the hollow region 44. In this way, the gas flow passage between the inner space 43 of the card seat 40 and the first space 101 of the housing 10 can be increased, and the propagation of gas between the inner space 43 of the card seat 40 and the first space 101 of the housing 10 can be further accelerated.

[0101] For example, the first elastic sheet 451 can be exposed relative to the hollow region 44 of the cover plate 41. In this way, the hollow region 44 of the cover plate 41 can be used to avoid the first elastic sheet 451 when the first elastic sheet 451 is deformed. For example, a portion of the hollow region 44 can be arranged on the bottom plate 42. The second elastic sheet 452 can be exposed relative to the hollow region 44 of the bottom plate 42. In this way, the hollow region 44 of the bottom plate 42 can be used to avoid the second elastic sheet 452 when the second elastic sheet 452 is deformed.

[0102] For example, the inner space 43 of the card seat 40 can also be in communication with the first through hole 15 of the housing 10, so that the inner space 43 of the card seat 40 can also be in communication with the outside of the housing 10 through the first through hole 15.

[0103] The card seat 40 can further include a first spring 451 and a second spring 452. The first spring 451 can be fixedly connected to the cover plate 41, and at least a portion of the first spring 451 can be located on a side of the cover plate 41 facing the bottom plate 42. In the embodiment of the present application, the first spring 451 can be used for electrical connection with a power supply of the electronic device 100. The first spring 451 can also be in communication connection with a controller (not shown in the figure) of the electronic device 100. It can be understood that the controller of the electronic device 100 can be installed in the internal space 10A of the shell 10. The controller of the electronic device 100 can be a chip or the like inside the electronic device 100.

[0104] The number of the first springs 451 can be multiple, and the multiple first springs 451 can be arranged at intervals in the X-Y plane. The number of the first springs 451 can be six, for example.

[0105] The second spring 452 can be fixedly connected to the bottom plate 42, and at least a portion of the second spring 452 can be located on a side of the bottom plate 42 facing the cover plate 41. In the embodiment of the present application, the second spring 452 can be used for electrical connection with a power supply of the electronic device 100. The second spring 452 can also be in communication connection with a controller (not shown in the figure) of the electronic device 100. It can be understood that the controller of the electronic device 100 can be a chip or the like inside the electronic device 100.

[0106] The number of the second springs 452 can be multiple, and the multiple second springs 452 can be arranged at intervals in the X-Y plane.

[0107] In some embodiments, the card seat 40 can further include a circuit board 46. The circuit board 46 is fixedly connected to the cover plate 41 and the bottom plate 42. The circuit board 46 can be in electrical connection with the first spring 451 and the second spring 452, for example.

[0108] Please refer to Figure 6 and Figure 7 , Figure 7 are Figure 5 the partial structure schematic view of the card seat 40 from another angle.

[0109] In some embodiments, the electronic device 100 can further include an ejecting assembly 47. The ejecting assembly 47 can be used for disengaging the card holder 50 from the card seat 40.

[0110] The ejecting assembly 47 can include a push rod 471 and a lever 472. The push rod 471 can be arranged along the Y-axis. The lever 472 can be connected to one end of the push rod 471. The lever 472 can be rotatably connected to the card holder 40. The cover plate 41 can be fixed to the circuit board 46 by a fastener 473. The lever 472 can be provided with a rotating hole 4721. The rotating hole 4721 can be sleeved on the fastener 473. The push rod 471 can be slidably connected to the card holder 40. The push rod 471 can move along the Y-axis to push the lever 472 to rotate relative to the fastener 473, so that one end of the lever 472 away from the push rod 471 can extend into or out of the internal space 43 of the card holder 40.

[0111] Please refer to Figure 8 to Figure 10 , Figure 8 is Figure 2 the structural schematic diagram of the card holder 50 in some embodiments, Figure 9 is Figure 8 the structural schematic diagram of the card holder 50 from another angle, Figure 10 is Figure 8 the partial sectional structural schematic diagram of the card holder 50 along A-A.

[0112] In some embodiments, the card holder 50 can include a main body part 51, an end part 52, and a connecting part 53. The connecting part 53 can be fixedly connected between the main body part 51 and the end part 52. In some examples, the connecting part 53 can be integrally formed with the end part 52. In other examples, the connecting part 53 can also be integrally formed with the main body part 51.

[0113] The main body part 51 of the card holder 50 can include first and second surfaces 511 and 512 arranged oppositely. For example, the first and second surfaces 511 and 512 can be arranged oppositely along the Z-axis. The main body part 51 of the card holder 50 can be provided with first and second card slots 54 and 55. The opening of the first card slot 54 can be located on the first surface 511 of the main body part 51. The opening of the second card slot 55 can be located on the second surface 512 of the main body part 51. It can be understood that in this embodiment, the first and second card slots 54 and 55 can be arranged oppositely along the Z-axis. In other embodiments, the first and second card slots 54 and 55 can be arranged spacedly along the X-axis. In other embodiments, the main body part 51 of the card holder 50 can further include a third card slot. The opening of the third card slot can be located on the first surface 511 of the main body part 51, and the third card slot can be arranged spacedly from the first card slot 54, for example, the third card slot and the first card slot 54 can be arranged spacedly along the Y-axis. Alternatively, the opening of the third card slot can be located on the second surface 512 of the main body part 51, and the third card slot can be arranged spacedly from the second card slot 55, for example, the third card slot and the second card slot 55 can be arranged spacedly along the Y-axis.

[0114] For example, the card holder 50 may also be provided with a limiting protrusion 56. The limiting protrusion 56 may surround the connecting portion 53 and be connected to the connecting portion 53.

[0115] For example, the end portion 52 may be provided with a second ejector pin hole 521. The second ejector pin hole 521 may extend through the end portion 52 along the Y-axis direction and be spaced apart from the connecting portion 53.

[0116] Please refer to the following: Figure 11 to Figure 13 , Figure 11 yes Figure 4 An enlarged view of part of the structure of the electronic device 100 shown at point A. Figure 12 yes Figure 4 The diagram shows a partial structural view of the electronic device 100 from another angle. Figure 13 yes Figure 12 The diagram shows a partial structural schematic of the card holder 40 and the card tray 50.

[0117] In some embodiments, the card holder 50 is detachably connected to the housing 10. Exemplarily, the card holder 50 is detachably inserted into the first through hole 15 of the housing 10. The internal space 43 of the card holder 40 may be disposed opposite to the first through hole 15 of the housing 10. When the card holder 50 is inserted into the first through hole 15, the main body 51 of the card holder 50 may extend into the internal space 43 of the card holder 40 and abut against the lever 472 of the card holder 40.

[0118] It is understood that in this embodiment, the card tray 50 is detachably connected to the card holder 40. For example, the card tray 50 is detachably inserted into the internal space 43 of the card holder 40. When the card tray 50 is separated from the housing 10, the card tray 50 is also separated from the card holder 40.

[0119] For example, the connecting portion 53 of the card holder 50 can be located within the first through hole 15 and engage with the inner wall of the first through hole 15. For instance, the inner wall of the first through hole 15 can be provided with a limiting groove 16, and at least a portion of the limiting protrusion 56 of the card holder 50 can be located within the limiting groove 16 of the first through hole 15. In other examples, the limiting protrusion 56 can also be provided on the inner wall of the first through hole 15, and the limiting groove 16 can also be provided on the connecting portion 53 of the card holder 50.

[0120] For example, the end 52 of the card holder 50 may be located within the limiting groove 16. The second ejector hole 521 of the end 52 is disposed opposite to the first ejector hole 17 of the housing 10.

[0121] One end of the push rod 471 can be inserted into the first ejector pin hole 17 of the housing 10. It is understood that the user can push the push rod 471 to move along the Y-axis direction by inserting the ejector pin into the first ejector pin hole 17 of the housing 10.

[0122] It can be understood that when the card holder 50 is inserted into the card slot 40, the other end of the push rod 472 can be used to abut against the card holder 50. When the push rod 471 pushes the push rod 472 to move, the push rod 472 can rotate relative to the card slot 40, and the other end of the push rod 472 can push the card holder 50 to move along the Y-axis direction, so that the end 52 of the card holder 50 can protrude from the limiting groove 16 of the shell 10. At this time, the user can pull out the card holder 50 to make the card holder 50 disengage from the card slot 40.

[0123] Please refer to Figure 14 , Figure 14 is Figure 12 the structural schematic diagram of the card slot 40 and the card holder 50 in another angle.

[0124] Please refer to Figure 15A to Figure 16 , Figure 15A is Figure 2 the structural schematic diagram of the fragrance card 60 in some embodiments, Figure 15B is Figure 15A the structural schematic diagram of the fragrance card 60 in another angle, Figure 16 is Figure 15A the partial structural exploded view of the fragrance card 60 in some embodiments. It can be understood that Figure 16 only some components included in the fragrance card 60 are schematically shown, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 16 . It can be understood that the fragrance card 60 can have more or fewer components.

[0125] In some embodiments, the fragrance card 60 can include a fragrance part 61, an encapsulation part 62 and a heating part 63. The fragrance part 61 has a fragrance. For example, the fragrance part 61 can be provided with a plurality of fragrance grooves. The fragrance grooves can be used to store the fragrance. It can be understood that the fragrance in the fragrance part 61 can generate fragrance when heated to a certain temperature. It can be understood that the fragrance is a gas with a specific fragrance, which can have a specific function (for example, helping sleep or refreshing, etc.), thereby being beneficial to improve the user's use experience.

[0126] The encapsulation part 62 can cover the fragrance of the fragrance part 61. The encapsulation film can be breathable and water-proof, and the encapsulation part 62 covering the fragrance of the fragrance part 61 can prevent the fragrance from leaking or being damp. For example, the encapsulation part 62 can be one or more layers of breathable and water-proof film, for example, it can be a single layer or multiple layers of Teflon film.

[0127] The heating part 63 can be connected to the fragrance part 61. The heating part 63 can be used to heat the fragrance part 61. For example, the heating part 63 can include a heating element 631, a first electrical connector 632, and a second electrical connector 633. The heating element 631 is electrically connected to the first electrical connector 632 and the second electrical connector 633. The heating element 631 is also connected to the fragrance part 61, for example, the heating element 631 can be attached to the surface of the fragrance part 61. For example, the heating element 631 can include metal, resistance wire (for example, a thermoelectric resistance wire), or a coil (for example, an electromagnetic heating coil), etc. The cost of the heating element 631 is low. It can be understood that when the heating element 631 is powered, it can convert electrical energy into internal energy, thereby heating the fragrance part 61 of the fragrance card 60. It can be understood that in this embodiment, the fragrance card 60 can release fragrance by heating. In some other embodiments, the fragrance card 60 can also release fragrance by applying force, electricity, sound, magnetism, light, or other ways to stimulate the fragrance. The application does not strictly limit the way the fragrance card 60 releases fragrance.

[0128] For example, the number of heating parts 63 can be multiple. For example, the multiple heating parts 63 can be arranged at intervals. The multiple heating parts 63 can be arranged one-to-one with multiple fragrance grooves. For example, the number of heating parts 63 and the number of fragrance grooves can both be six, and the six heating parts 63 are arranged one-to-one with the six fragrance grooves. Each heating part 63 can be used to heat the corresponding fragrance groove to stimulate the fragrance in the corresponding fragrance groove to release fragrance.

[0129] It can be understood that in this application, the fragrance part 61 can be used to store one or more fragrances. When the fragrance part 61 is used to store multiple fragrances, the multiple fragrances can be arranged at different positions on the fragrance part 61, and each position corresponding to a fragrance can be provided with a corresponding heating part 63 to achieve multiple different fragrance functions. For example, the fragrance part 61 can store three fragrances. The placement position of each fragrance corresponds to at least one heating part 63, and the first electrical connector 632 and the second electrical connector 633 of each heating part 63 can be electrically connected to two first spring sheets 451, respectively.

It can be understood that, in the embodiments of the present application, the fragrance card 60 can be detachably connected to the shell 10 through the cooperation of the card holder 50 and the card seat 40. It can be understood that, when the card holder 50 is connected to the shell 10, the fragrance card 60 can also not be placed in the card holder 50. At this time, the fragrance card 60 is separated from the shell 10.

[0133] In some embodiments, the shape and size of the fragrance card 60 are the same as the shape and size of the SIM card of the electronic device 100. At this time, the shape and size of the first card slot 54 are the same as the shape and size of the second card slot 55. In this way, the fragrance card 60 and the SIM card can use the first card slot 54 and the second card slot 55. At this time, the structure design of the first card slot 54 and the second card slot 55 can be the same, so that the manufacturing process of the card holder 50 can be simplified. In addition, when the user inserts the fragrance card 60 or the SIM card, it is not necessary to identify the card slot corresponding to the fragrance card 60 or the SIM card, which can simplify the assembly process of the fragrance card 60 and the SIM card, and is conducive to improving the user experience. In other embodiments, the shape and / or size of the fragrance card 60 can also be different from the shape of the SIM card. The present application does not make strict limitations in this regard.

The heating element 631 (see Figure 16 ) is powered to generate heat, and heats the fragrance part 61 of the fragrance card 60, so that the fragrance in the fragrance part 61 (see Figure 16 ) can generate fragrance. The fragrance generated by the fragrance card 60 can be transmitted through the hollow area 44 of the card seat 40 to the air duct 1011, and then transmitted through the air duct 1011 to the internal space of the speaker 30, and then transmitted through the first sound outlet 14 of the electronic device 100 to the outside of the shell 10, thereby realizing the fragrance diffusion function of the electronic device 100. It can be understood that in the embodiments of the present application, the air duct 1011 is used to transmit the fragrance generated by the fragrance card 60 to the first sound outlet 14. The first sound outlet 14 is used to transmit the fragrance in the air duct 1011 to the outside of the shell 10, thereby realizing the fragrance diffusion function of the electronic device.

[0140] It can be understood that in the embodiments of the present application, the first sound outlet 14 has the effect of "one thing with multiple uses". On the one hand, the first sound outlet 14 can serve as a sound outlet channel of the speaker 30. The sound emitted by the speaker 30 can be transmitted through the first sound outlet 14 to the outside of the shell 10, thereby realizing the audio playback function of the electronic device 100. On the other hand, the fragrance generated by the fragrance card 60 can also be transmitted through the first sound outlet 14 to the outside of the shell 10. In this way, the shell 10 of the electronic device 100 does not need to additionally open a through hole for diffusing fragrance, thereby reducing the number of openings of the shell 10 of the electronic device 100, making the appearance integrity of the electronic device 100 better, and not easily introducing dust and water vapor.

[0141] In the embodiments of the present application, the internal space 10A of the shell 10 is divided into the first space 101 by the partition 13, and the speaker 30 and the card seat 40 are both installed in the first space 101. In this way, the air duct 1011 can be set to be relatively short, so that the transmission path of the fragrance generated by the fragrance card 60 can be relatively short, which is beneficial to improving the transmission rate of the fragrance, thereby being beneficial to improving the fragrance diffusion effect of the electronic device 100.

[0142] In addition, in the embodiments of the present application, the card seat 40 and the speaker 30 can both be installed in the first space 101 of the shell 10. In this way, the card seat 40 can be arranged close to the speaker 30, so that the distance between the card seat 40 and the speaker 30 can be reduced, thereby the ultrasonic waves generated by the speaker 30 can better drive the fragrance to propagate.

[0143] In addition, it can be understood that the fragrance card 60 needs to be replaced as a consumable. In the present embodiment, by providing the card holder 50 for placing the fragrance card 60, and the fragrance card 60 is inserted into the card seat 40 through the card holder 50, the connection of the fragrance card 60 and the shell 10, that is, the installation of the fragrance card 60 on the shell 10, can be realized, and the replacement of the fragrance card 60 is facilitated. In some other embodiments, the electronic device 100 can not include the card seat 40 and the card holder 50. The fragrance card 60 can be directly clamped with the shell 10, so as to be detachably connected to the shell 10.

[0144] Please continue to refer to Figure 18A In some embodiments, the electronic device 100 can further include a temperature sensor 70 and a controller 80. The temperature sensor 70 and the controller 80 can be installed in the first space 101 of the shell 10. The controller 80 can be fixedly connected to the circuit board 46 of the card seat 40 and electrically connected with the circuit board 46. In some other examples, the controller 80 can also be installed at other positions of the internal space 10A of the shell 10, which is not strictly limited in the present application. The temperature sensor 70 can be fixed to the cover plate 41 and / or the bottom plate 42 of the shell 10 and arranged close to the card seat 40. In some other examples, the temperature sensor 70 can also be arranged on the card seat 40. The temperature sensor 70 is used to detect the temperature of the fragrance card 60.

[0145] It can be understood that the temperature sensor 70 can be used to detect whether the temperature of the fragrance card 60 reaches a predetermined range, that is, whether the excitation temperature of the fragrance on the fragrance card 60 is reached. For example, the temperature sensor 70 can include a negative temperature coefficient (NTC) thermistor sensor.

[0146] In the present embodiment, the temperature sensor 70 can be in communication connection with the controller 80 of the electronic device 100, so that the controller 80 of the electronic device 100 can control the working state of the heating part 63 according to the detection value of the temperature sensor 70. It can be understood that the working state of the heating part 63 refers to the power-on state of the heating element 631 of the heating part 63. For example, when the temperature sensor 70 detects that the temperature of the fragrance card 60 is less than the excitation temperature of the fragrance, the controller 80 can be used to control the heating element 631 to be continuously powered on, so that the temperature of the heating element 631 continuously rises. When the temperature sensor 70 detects that the temperature of the fragrance card 60 is greater than or equal to the excitation temperature of the fragrance, the controller 80 can also be used to control the heating element 631 to be periodically powered on, so that the temperature of the heating element 631 is maintained within a certain range. In this way, the fragrance can be heated to release fragrance, and the temperature is not too high to cause the fragrance to be consumed too quickly. At the same time, the high temperature can also avoid affecting the SIM card or other devices of the electronic device 100.

[0147] In some other embodiments, the temperature sensor 70 can also be arranged on the fragrance card 60. In this way, the temperature sensor 70 can more accurately detect the temperature of the fragrance card 60.

[0148] In some embodiments, when the fragrance card 60 is in the non-working state, the electronic device 100 is in the first state. At this time, the loudspeaker 30 can be used to play audio to realize the audio playing function of the electronic device 100. When the fragrance card 60 is installed in the shell 10 and in the working state, the electronic device 100 is in the second state. That is, when the fragrance card 60 is installed in the shell 10, the loudspeaker 30 can be used to play audio and generate ultrasonic waves. For example, when the fragrance card 60 is inserted into the card seat 40 and generates fragrance, the loudspeaker 30 can generate ultrasonic waves, so that the ultrasonic waves can accelerate the propagation speed of the fragrance inside the loudspeaker 30, so that the fragrance can be quickly propagated to the first sound hole 14 and then to the outside of the shell 10. In this way, the electronic device 100 can have a better fragrance diffusion effect.

[0149] Please refer to Figure 18B , Figure 18B is Figure 4 the partial structure schematic diagram of the electronic device 100 in some other embodiments. The exemplary, Figure 18B mainly shows the assembly structure schematic diagram of the card seat 40, the card holder 50 and the fragrance card 60.

[0150] In some other embodiments, the electronic device can include a heating assembly 104. The heating assembly 104 can be installed in the internal space 10A of the shell 10 and electrically connected with the power supply of the electronic device 100. For example, the heating assembly 104 can be fixedly connected with the card seat 40. When the fragrance card 60 is inserted into the card seat 40, the heating assembly 104 can be connected with the fragrance part 61 of the fragrance card 60. The heating assembly 104 can be used to heat the fragrance part 61 of the fragrance card 60, so that the fragrance card 60 can emit fragrance. In addition, in this embodiment, by arranging the heating assembly 104 in the first space 101, when the fragrance card 60 is replaced, the heating assembly 104 does not need to be replaced, which is beneficial to save cost.

[0151] In this embodiment, the structure of the heating assembly 104 is the same as or similar to that of the heating part 63 of the fragrance card 60 in the above embodiment. The structure of the heating assembly 104 can refer to the related description of the heating part 63 of the fragrance card, which will not be described here.

[0152] It can be understood that in this embodiment, the fragrance card 60 can not include the heating part.

[0153] Please refer to Figure 18A and Figure 19 , Figure 19 is Figure 2A partial structural schematic diagram of the electronic device 100 in some embodiments is shown.

[0154] In some embodiments, the electronic device 100 can further include a change-over switch 90, a first power supply 91, and a second power supply 92. In some examples, the change-over switch 90, the first power supply 91, and the second power supply 92 are all installed in the internal space 10A of the housing 10. For example, the change-over switch 90 can be installed in the first space 101 of the housing 10. For example, the change-over switch 90 can be fixedly connected to the circuit board 46 of the card seat 40 and electrically connected to the circuit board 46. For example, the change-over switch 90 can be electrically connected to a Power Management Unit (PMU) chip on the circuit board 46. In other examples, the change-over switch 90, the first power supply 91, and the second power supply 92 can also be installed at other positions in the internal space 10A of the housing 10, which are not limited in the present application.

[0155] In some embodiments, the change-over switch 90 can be electrically connected between the first power supply 91 and the fragrance card 60, and the change-over switch 90 can also be electrically connected between the second power supply 92 and the SIM card of the electronic device 100. In some examples, the change-over switch 90 can be electrically connected to the fragrance card 60 and the SIM card of the electronic device 100 through the card seat 40. For example, Figure 19 The electrical connection relationship between the first power supply 91, the second power supply 92, the change-over switch 90, the fragrance card 60, and the SIM card of the electronic device 100 is shown only schematically. It can be understood that, Figure 19 The actual shape, actual size, actual position, and actual structure of the components shown in the above Figure 19 are not limited.

[0156] For example, the working voltage of the first power supply 91 can be adapted to the working voltage of the fragrance card 60. When the fragrance card 60 is inserted into the card seat 40 and in a working state, the change-over switch 90 can turn on the circuit between the first power supply 91 and the fragrance card 60, so that the first power supply 91 can supply power to the fragrance card 60, and then the heating part 63 can be powered on to heat the fragrance part 61 of the fragrance card 60, so that the fragrance card 60 emits fragrance. In some examples, when the fragrance card 60 is placed in the first card slot 54 of the card holder 50, the first power supply 91 can be electrically connected to the first spring sheet 451 of the card seat 40, thereby electrically connecting the fragrance card 60. In other examples, when the fragrance card 60 is placed in the second card slot 55 of the card holder 50, the first power supply 91 can be electrically connected to the second spring sheet 452 of the card seat 40, thereby electrically connecting the fragrance card 60.

[0157] The working voltage of the second power supply 92 can be adapted to the working voltage of the SIM card. When the SIM card is inserted into the card seat 40 and is in a working state, the change-over switch 90 can conduct the circuit between the second power supply 92 and the SIM card, so that the second power supply 92 can supply power to the SIM card. The electronic device 100 can realize the data reading function of the SIM card. In some examples, when the SIM card is placed in the first card slot 54 of the card holder 50, the second power supply 92 can be electrically connected with the first spring sheet 451 of the card seat 40, so as to electrically connect the SIM card. When the SIM card is placed in the second card slot 55 of the card holder 50, the second power supply 92 can be electrically connected with the second spring sheet 452 of the card seat 40, so as to electrically connect the SIM card.

[0158] In the embodiment of the present application, the electronic device 100 can switch the power supply signal through the change-over switch 90 to supply power to the fragrance card 60 and the SIM card of the electronic device 100, so as to ensure the normal use of the fragrance card 60 and the SIM card, and the cost of the electronic device 100 is relatively low.

[0159] It can be understood that, in the embodiment, the working voltage of the second power supply 92 is different from the working voltage of the first power supply 91. In other embodiments, the working voltage of the second power supply 92 can also be the same as the working voltage of the first power supply 91. The present application does not make strict limitation in this regard.

[0161] Please refer to Figure 19 and Figure 20 , Figure 20 is a flowchart of a control method of an electronic device 100 provided in an embodiment of the present application.

[0162] In some embodiments, the control method of the electronic device 100 can include:

[0163] S100: The controller 80 reads the data of the card and identifies the type of the card when the card is installed in the shell 10. It can be understood that when the card is inserted into the card seat 40 through the card holder 50 and is connected to the shell 10, the controller 80 can read the data of the card in the first card slot 54 of the card holder 50 and identify the type of the card in the first card slot 54; and / or the controller 80 can read the data of the card in the second card slot 55 of the card holder 50 and identify the type of the card in the second card slot 55.

[0165] If the card is a SIM card, S201 is performed: the controller 80 controls the screen 20 of the electronic device 100 to display “SIM card”.

[0166] Otherwise, S300 is performed: the controller 80 determines whether the card is a fragrance card 60.

[0167] If the card is a fragrance card 60, S301 is performed: the controller 80 controls the screen 20 of the electronic device 100 to display “fragrance card 60”.

[0168] Otherwise, S302 is performed: the controller 80 controls the screen 20 of the electronic device 100 to display “no card”.

[0169] It can be understood that in the above control method, S200 and S300 can be exchanged, that is, after S100, S200 can be performed first, and then S300 can be performed, or S300 can be performed first, and then S200 can be performed. The present application does not make strict limitation on this.

[0170] In some embodiments, the control method of the electronic device 100 can further include:

[0171] After S201, S202 is performed: the change-over switch 90 is turned on to the circuit between the second power supply 92 and the SIM card. In this way, the second power supply 92 can supply power to the SIM card through the change-over switch 90.

[0172] In some embodiments, S202 further includes: the controller 80 is in communication connection with the SIM card. The electronic device 100 can realize the data reading function of the SIM card. It can be understood that the controller 80 can transmit the SIM card signal through the change-over switch 90.

[0173] In some embodiments, the control method of the electronic device 100 can further include:

[0174] After S301, S400 is performed: the controller 80 determines whether the user has turned on the fragrance function.

[0175] If the user turns on the fragrance function, S401 is performed: the conversion switch 90 is turned on to connect the circuit between the first power supply 91 and the fragrance card 60. In this way, the first power supply 91 can supply power to the fragrance card 60 through the conversion switch 90, so that the heating part 63 can heat the fragrance part 61 of the fragrance card 60 to realize the fragrance diffusion function of the fragrance card 60. At this time, the controller 80 can transmit the fragrance card 60 signal through the conversion switch 90.

[0176] Otherwise, return to S301.

[0177] Please refer to Figure 21 , Figure 21 is a flowchart of a control method of an electronic device 100 provided by an embodiment of the present application.

[0178] In some embodiments, the control method of the electronic device 100 can further include:

[0179] After S301, S500 is performed: the temperature sensor 70 detects the temperature of the fragrance card 60 and transmits a detection signal to the controller 80. It can be understood that the controller 80 can control the heating temperature of the heating part 63 according to the detection value of the temperature sensor 70. For example, the controller 80 can control the heating temperature of the heating element 631 of the heating part 63 according to the detection value of the temperature sensor 70. It can be understood that in the control method of the present application, the temperature of the heating element 631 of the heating part 63 can be controlled by controlling the working state of the heating part 63.

[0180] After S500, S501 is performed: it is judged whether the detection value is within a predetermined range.

[0181] If the detection value of the temperature sensor 70 is within the predetermined range, S5011 is performed: the controller 80 controls the heating temperature of the heating element 631 of the heating part 63 to be maintained within the predetermined range. For example, the controller 80 controls the periodic conduction and disconnection of the circuit, thereby controlling the periodic conduction and disconnection of the heating part 63, so as to maintain the heating temperature of the heating element 631 of the heating part 63 within the predetermined range. It can be understood that the excitation temperature of the fragrance of the fragrance card 60 is within the predetermined range.

[0182] Otherwise, S502 is performed: it is judged whether the detection value is greater than the predetermined range.

[0183] If the detection value of the temperature sensor 70 is greater than the predetermined range, S5021 is performed: the controller 80 controls the heating temperature of the heating element 631 of the heating part 63 to be reduced. For example, the conversion switch 90 is used to disconnect the circuit between the first power supply 91 and the fragrance card 60, so that the first power supply 91 stops supplying power to the heating part 63 of the fragrance card 60.

[0184] Otherwise, S503 is performed: the controller 80 controls the heating temperature of the heating element 631 of the heating part 63 to rise. For example, the change-over switch 90 continues to conduct the circuit between the first power supply 91 and the fragrance card 60, so that the first power supply 91 can continue to supply power to the heating part 63 of the fragrance card 60.

[0185] It can be understood that in the above embodiment, the electronic device 100 can switch the power supply signal through the change-over switch 90 to supply power to the fragrance card 60 and the SIM card of the electronic device 100, so as to ensure the normal use of the fragrance card 60 and the SIM card of the electronic device 100. In some other embodiments, the electronic device 100 can also switch the power supply signal in other ways. Hereinafter, another structure of the electronic device 100 and the way of switching the power supply signal will be introduced in combination with the related drawings.
