Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] Current portable electronic devices are often provided with sound holes to play audio, but the sound holes are always open, and dust and other foreign matter can easily enter the electronic device through the sound holes, making the electronic device less dustproof and less sealed. Summary of the invention

[0003] The purpose of the present application is to provide an electronic device that can effectively solve the problems of poor dustproof effect and poor sealing of the electronic device.

[0004] In a first aspect, the present application provides an electronic device, comprising a housing, an electric sound converter, a partition, and a driving mechanism. The housing is provided with a sound outlet hole and a sound outlet channel, the sound outlet hole is connected to the outside of the housing, and the sound outlet channel is provided on the inside of the housing. The electric sound converter, the partition, and the driving mechanism are all installed on the inside of the housing, and the driving mechanism is used to drive the partition to move between a first position and a second position.

[0005] When the partition is located at the first position, the partition blocks the sound outlet hole and the sound outlet channel.

[0006] The partition blocks the sound hole and the sound channel, which means that the partition blocks the sound hole and the sound channel, and the sound hole and the sound channel are not connected. Exemplarily, the partition blocks the opening of the sound hole toward the sound channel, or the partition blocks the opening of the sound channel toward the sound hole.

[0007] At this time, the sound from the electric energy sound converter cannot be transmitted to the outside of the shell through the sound outlet channel and the sound outlet hole. External dust and other impurities cannot enter the sound outlet channel through the sound outlet hole, thus preventing external dust and other impurities from entering the inside of the shell, ensuring the dustproof effect of the electronic equipment and improving the sealing of the electronic equipment.

[0008] When the partition is located at the second position, the sound outlet hole is connected to the sound outlet channel, and the sound emitted by the electric energy sound converter is transmitted to the outside of the shell through the sound outlet channel and the sound outlet hole, thereby realizing the sound playback of the electronic device.

[0009] In the electronic device shown in the present application, a driving mechanism is used to drive the partition to move between a first position and a second position to achieve connectivity between the sound outlet hole and the sound outlet channel. When the electronic device does not need to use the sound outlet hole to play sound, the sound outlet hole and the sound outlet channel can be blocked. When the electronic device needs to use the sound outlet hole to play sound, the sound outlet hole and the sound outlet channel can be connected.

[0010] In one embodiment, the housing is provided with a receiving hole. Alternatively, the electronic device further comprises a display screen, the display screen is mounted on the housing, the display screen is provided with a receiving hole, or the display screen and the housing are enclosed to form the receiving hole.

[0011] The receiving hole is connected to the sound output channel.

[0012] When the partition is in the first position, the sound emitted by the electric energy sound converter cannot be transmitted to the outside of the shell through the sound outlet channel and the sound outlet hole, but can be transmitted to the outside of the shell through the sound outlet channel and the receiver hole, thereby realizing the sound playback of the electronic device. At this time, the electronic device is in the handset mode. In other words, the electric energy sound converter is used as a handset of the electronic device. When the user uses the electronic device handheld, the user can only hear the sound from the receiver hole, which can effectively prevent the sound emitted by the electric energy sound converter from being transmitted to the outside of the shell through the sound outlet hole, that is, it prevents the sound emitted by the electric energy sound converter from leaking to the external environment through the sound outlet hole, which can effectively improve the sound leakage problem of the electronic device and ensure the user's personal privacy.

[0013] When the partition is in the second position, the sound emitted by the electric energy sound converter can not only be transmitted to the outside of the shell through the sound outlet channel and the sound outlet hole, but also be transmitted to the outside of the shell through the sound outlet channel and the receiver hole, so as to realize the sound playback of the electronic device. At this time, the electronic device is in the external speaker mode. In other words, the electric energy sound converter is used as a speaker of the electronic device. When the user holds the electronic device, he can hear the sound from the receiver hole and the sound outlet hole at the same time, which is not only conducive to expanding the sound output area of ​​the electric energy sound converter and improving the sound loudness of the electric energy sound converter, but also conducive to optimizing the stereo effect.

[0014] In the present application, the width direction of the electronic device is the X-axis direction, the length direction of the electronic device is the Y-axis direction, and the thickness direction of the electronic device is the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0015] In one embodiment, the driving mechanism includes a base, a first fixed claw, a second fixed claw, a first memory wire and a second memory wire. The partition can slide relative to the base along the Z-axis direction. The partition includes a first movable claw and a second movable claw, and the first movable claw and the second movable claw are arranged at intervals along the X-axis direction.

[0016] Exemplarily, the base is provided with a slide groove, and the partition is installed in the slide groove and can slide in the slide groove relative to the base along the Z-axis direction.

[0017] The first fixed claw and the second fixed claw are both mounted on the base and arranged at intervals along the X-axis direction. The first fixed claw is closer to the first movable claw relative to the second fixed claw, and the second fixed claw is closer to the second movable claw relative to the first fixed claw.

[0018] The first fixed claw and the second fixed claw are respectively located on opposite sides of the partition. The first fixed claw is located on one side of the partition close to the first movable claw, and the second fixed claw is located on one side of the partition close to the second movable claw.

[0019] One end of the first memory metal wire is fixedly connected to the first fixed claw, and the other end is fixedly connected to the second movable claw. One end of the second memory metal wire is fixedly connected to the second fixed claw, and the other end is fixedly connected to the first movable claw.

[0020] When the first memory metal wire and the second memory metal wire are both energized and their lengths are shortened, the partition moves from the first position to the second position.

[0021] When the first memory metal wire and the second memory metal wire are both powered off and their lengths are extended, the partition moves from the second position to the first position.

[0022] The memory metal wire is made of shape memory alloy material. Shape memory alloy is a general term for metals with shape memory effect, such as nickel-titanium alloys such as titanium-nickel-copper, titanium-nickel-iron or titanium-nickel-chromium, or copper-nickel alloys, or copper-aluminum alloys, or copper-zinc alloys, or iron alloys.

[0023] It should be noted that, generally, when a metal material is subjected to an external force, the first thing that occurs is elastic deformation. If the external force is removed at this time, the metal will return to its original shape. If the external force continues to increase, when the metal reaches its own yield point, plastic deformation will occur. After the external force is eliminated, permanent deformation will remain, and the shape will not recover even if heated. Shape memory alloy is an alloy material that can completely eliminate the deformation that occurs at a lower temperature after heating and restore its original shape before deformation. The basic principle of the working of shape memory alloy material is to heat the material to a certain critical temperature for shape memory heat treatment (training), and cause it to undergo a certain deformation. After cooling to form a martensite phase, when it is heated again to above the critical temperature, the low-temperature martensite phase reverses to a high-temperature austenite phase (i.e., a reverse transformation occurs), thereby restoring to the state memorized before deformation.

[0024] In the present application, when the memory wire is energized, the heat generated by the current flowing through the memory wire causes the temperature of the memory wire to rise, realizing the reverse phase transformation from the low-temperature martensite phase to the high-temperature austenite phase, restoring the memory before deformation, thereby causing the memory wire to contract. The change in length caused by the contraction of the memory wire is essentially caused by the transformation of the material's crystal phase structure, that is, the transformation between martensite and austenite. The gravitational force between microscopic particles caused by the change in crystal structure (that is, the transformation of the gaps between atoms) makes the pulling force of the memory wire larger when it contracts macroscopically. Therefore, the contraction of the memory wire can drive a heavier load, that is, it can achieve a large load, so the drive mechanism can achieve a larger driving force with a smaller size. The small-sized drive mechanism is conducive to reducing the space occupied inside the electronic device and realizing the miniaturized design of the electronic device.

[0025] The first position is located on the side of the second position facing the negative direction of the Z axis. At this time, the direction from the first position to the second position is the positive direction of the Z axis. The direction from the second position to the first position is the negative direction of the Z axis.

[0026] When the first memory metal wire and the second memory metal wire are both energized, the first memory metal wire and the second memory metal wire shrink due to the increase in temperature, and the lengths of the first memory metal wire and the second memory metal wire are shortened, which will generate a pulling force on the separator along the positive direction of the Z axis, driving the separator to move along the positive direction of the Z axis.

[0027] When the first memory metal wire and the second memory metal wire are both powered off, the first memory metal wire and the second memory metal wire will not shrink due to the temperature increase. At this time, the first memory metal wire and the second memory metal wire can be stretched and deformed under the action of external force to extend in length.

[0028] Exemplarily, the separator can move along the negative direction of the Z axis under the action of external force, and the separator will generate a pulling force along the negative direction of the Z axis on the first memory metal wire and the second memory metal wire, so that the first memory metal wire and the second memory metal wire are stretched and deformed and their lengths are extended.

[0029] In one embodiment, the driving mechanism further includes a reset member connected between the base and the partition member.

[0030] When the first memory metal wire and the second memory metal wire are both powered off, the reset member is used to drive the partition to move from the second position to the first position, so that the first memory metal wire and the second memory metal wire are stretched and deformed and lengthened under the drive of the partition.

[0031] Exemplarily, the reset member is a tension spring, and the elastic force direction of the reset member is the Z-axis direction. When the partition is in the first position, the reset member is in a free state or a compressed state. When the partition is in the second position, the reset member is in a tension state.

[0032] When the first memory metal wire and the second memory metal wire are both powered off, the reset member in the stretched state will return to its original shape and shorten in length, and the reset member will generate a pulling force on the separator along the negative direction of the Z axis, driving the separator to move along the second position toward the first position, so that the first memory metal wire and the second memory metal wire are stretched and deformed and their length is extended under the drive of the separator.

[0033] In addition, the reset member is connected between the separator and the base, and can also limit the separator in the Z-axis direction, limiting the moving distance of the separator relative to the base along the Z-axis direction, ensuring the connection stability between the separator and the base, and improving the connection stability between the separator and the driving mechanism.

[0034] In one embodiment, there are two reset members, both of which are connected between the base and the partition and are arranged at intervals along the X-axis direction to improve the connection stability between the base and the partition.

[0035] In one embodiment, the driving mechanism includes a base, a first fixed claw, a second fixed claw, a first memory wire and a second memory wire. The separator can slide relative to the base along the Y-axis direction, and the separator includes a first movable claw and a second movable claw, and the first movable claw and the second movable claw are arranged at intervals along the X-axis direction.

[0036] Exemplarily, the base is provided with a slide groove, and the partition is installed in the slide groove and can slide in the slide groove relative to the base along the Y-axis direction.

[0037] The first fixed claw and the second fixed claw are both installed on the side of the base away from the partition and are arranged at intervals along the X-axis direction. The first fixed claw is closer to the first movable claw relative to the second fixed claw, and the second fixed claw is closer to the second movable claw relative to the first fixed claw.

[0038] One end of the first memory metal wire is fixedly connected to the first fixed claw, and the other end is fixedly connected to the second movable claw. One end of the second memory metal wire is fixedly connected to the second fixed claw, and the other end is fixedly connected to the first movable claw.

[0039] When the first memory metal wire and the second memory metal wire are both energized and their lengths are shortened, the partition moves from the first position to the second position.

[0040] When the first memory metal wire and the second memory metal wire are both powered off and their lengths are extended, the partition moves from the second position to the first position.

[0041] The first position is located on the side of the second position facing the negative direction of the Y axis. At this time, the direction from the first position to the second position is along the positive direction of the Y axis. The direction from the second position to the first position is along the negative direction of the Y axis.

[0042] When both the first memory metal wire and the second memory metal wire are energized, the first memory metal wire and the second memory metal wire shrink due to the increase in temperature, and the lengths of the first memory metal wire and the second memory metal wire are shortened, which will generate a pulling force on the separator along the positive direction of the Y axis, driving the separator to move along the positive direction of the Y axis.

[0043] When the first memory metal wire and the second memory metal wire are both powered off, the first memory metal wire and the second memory metal wire will not shrink due to the temperature increase. At this time, the first memory metal wire and the second memory metal wire can be stretched and deformed under the action of external force to extend in length.

[0044] Exemplarily, the separator can move along the negative direction of the Y axis under the action of external force, and the separator will generate a pulling force along the negative direction of the Y axis on the first memory metal wire and the second memory metal wire, so that the first memory metal wire and the second memory metal wire are stretched and deformed and their lengths are extended.

[0045] In one embodiment, the driving mechanism further includes a reset member connected between the base and the partition member.

[0046] When the first memory metal wire and the second memory metal wire are both powered off, the reset member is used to drive the partition to move from the second position to the first position, so that the first memory metal wire and the second memory metal wire are stretched and extended in length driven by the partition.

[0047] Exemplarily, the reset member is a compression spring, and the elastic force direction of the reset member is the Y-axis direction. When the partition is in the first position, the reset member is in a free state. When the partition is in the second position, the reset member is in a compressed state.

[0048] When the first memory metal wire and the second memory metal wire are both powered off, the reset member in the compressed state returns to its original shape and its length is extended. The reset member generates a thrust along the negative direction of the Y-axis on the separator, pushing the separator to move along the second position toward the first position, thereby causing the first memory metal wire and the second memory metal wire to be stretched and extended in length driven by the separator.

[0049] In addition, the reset member is connected between the separator and the base, and can also limit the separator in the Y-axis direction, limiting the moving distance of the separator relative to the base along the Y-axis direction, ensuring the connection stability between the separator and the base, and improving the overall structural stability of the driving mechanism.

[0051] In one embodiment, the driving mechanism further includes a first base and a second base, both of which are mounted on a side of the base away from the partition and spaced apart along the X-axis direction. The first base is closer to the first movable claw relative to the second base, and the second base is closer to the second movable claw relative to the first base.

[0059] When the first memory metal wire is energized and its length is shortened, the partition moves from the first position to the second position.

[0060] When the first memory metal wire is powered off and its length is extended, the partition moves from the second position to the first position.

At this time, the direction from the first position to the second position is along the positive direction of the X-axis. The direction from the second position to the first position is along the negative direction of the X-axis.

[0062] When the first memory metal wire is energized, it contracts due to the increase in temperature, and the length of the first memory metal wire is shortened. The first memory metal wire will generate a pulling force along the positive direction of the X-axis on the separator, driving the separator to move along the positive direction of the X-axis.

[0063] When the first memory metal wire is powered off, the first memory metal wire will not shrink due to the temperature rise. At this time, the first memory metal wire can be stretched and deformed under the action of external force to extend its length.

The circuit board 130, the processor 140, the electric energy sound converter 150 and the switch assembly 160 are all mounted on the inner side of the housing 110.

[0156] The shell 110 is provided with a mounting groove 1101, a sound outlet channel (not shown) and a sound outlet hole 1102. The mounting groove 1101, the sound outlet hole 1102 and the sound outlet channel 1142 are all located at the top of the shell 110. The opening of the mounting groove 1101 is located at the front of the shell 110. The mounting groove 1101 extends from the front to the back of the shell 110. That is, the front of the shell 110 is partially recessed to form the mounting groove 1101. The sound outlet channel is arranged on the inner side of the shell 110. Among them, the sound outlet channel passes through the groove wall of the mounting groove 1101. Exemplarily, the sound outlet channel passes through the groove side wall of the mounting groove 1101.

The sound hole 1102 extends from the outer side of the housing 110 to the mounting slot 1101, and passes through the slot wall of the mounting slot 1101. That is, the outer side of the housing 110 is partially recessed to form the sound hole 1102. Exemplarily, the sound hole 1102 passes through the slot side wall of the mounting slot 1101. In some other embodiments, the sound hole 1102 may also pass through the slot bottom wall of the mounting slot 1101.

[0158] In this embodiment, there are five sound holes 1102, and the five sound holes 1102 are arranged at intervals along the X-axis direction. In some other embodiments, there may be one, two, three, four or more than six sound holes 1102, and the present application does not specifically limit the number of sound holes 1102. It should be understood that the "hole" described in the embodiment of the present application refers to a hole with a complete hole wall. The description of "hole" in the following text can be understood in the same way.

[0159] In one embodiment, the shell 110 includes a middle frame 111 and a back cover 112, and the back cover 112 is installed on one side of the middle frame 111. The middle frame 111 is provided with a mounting groove 1101, a sound outlet hole 1102 and a sound outlet channel. Specifically, the mounting groove 1101, the sound outlet hole 1102 and the sound outlet channel are all located at the top of the middle frame 111. The opening of the mounting groove 1101 is located on the front of the middle frame 111, and the opening of the sound outlet hole 1102 is located on the outer side of the middle frame 111. At this time, the front of the middle frame 111 is the front of the shell 110, and the outer side of the middle frame 111 is the outer side of the shell 110.

[0160] The back cover 112 is mounted on the back side of the middle frame 111 and is enclosed with the middle frame 111 to form a receiving cavity (not shown). Exemplarily, the back cover 112 is detachably mounted on the middle frame 111 to facilitate replacement and repair of electronic components located in the receiving cavity. In some other embodiments, the back cover 112 can also be assembled with the middle frame 111 to form an integrated structure to increase the overall strength of the housing 110.

[0161] It should be noted that the directional words such as "front", "back", "top", "bottom", "inside" and "outside" mentioned in the embodiments of the present application are based on Figure 1 The directions shown are described, along the Z-axis direction, the positive direction of the Z-axis (i.e., toward the display screen 120) is positive, and the negative direction of the Z-axis (i.e., away from the display screen 120) is negative, along the Y-axis direction, the positive direction of the Y-axis is the top, the negative direction of the Y-axis is the bottom, the interior of the electronic device 100 is the "inside", and the exterior of the electronic device 100 is the "outside", which does not limit the direction of the electronic device 100 in actual application scenarios.

Among them, the installation groove 1101 is exposed relative to the display screen 120. That is, the display screen 120 does not completely block the installation groove 1101. Exemplarily, the display screen 120 blocks a part of the opening of the installation groove 1101. At this time, the unblocked part of the opening of the installation groove 1101 forms the sound receiving hole 1103. That is, the display screen 120 and the middle frame 111 of the housing 110 enclose to form the sound receiving hole 1103. Among them, the sound receiving hole 1103 communicates with the sound outlet channel.

[0163] In some other embodiments, the display screen 120 may also not block the installation groove 1101 at all. At this time, the opening of the installation groove 1101 forms the sound receiving hole 1103. That is, the housing 110 is provided with the sound receiving hole 1103, or the display screen 120 is provided with the sound receiving hole 1103, and the sound receiving hole 1103 communicates with the installation groove 1101 to communicate with the sound outlet channel.

Specifically, the first portion 132 and the second portion 133 of the circuit board 130 are respectively mounted on the two second notches 1143 (such as Figure 4 As shown). For example, the first part 132 is installed on the bottom wall of the second right notch 1143a by bonding, and the second part 133 is installed on the bottom wall of the second left notch 1143b by bonding. At this time, the electric energy sound converter 150 is located in the avoidance space 1301 (as shown in FIG. Figure 2 That is, the circuit board 130 is disposed around the periphery of the electric energy sound converter 150.

[0185] The switch assembly 160 is located between the sound outlet hole 1102 and the sound outlet channel 1142. In this embodiment, when the switch assembly 160 is in the closed state, the switch assembly 160 blocks the opening of the sound outlet hole 1102 toward the mounting slot 1101 to block between the sound outlet hole 1102 and the mounting slot 1101, thereby blocking the sound outlet hole 1102 and the sound outlet channel 1142. At this time, the sound outlet hole 1102 is not connected to the mounting slot 1101, that is, the sound outlet hole 1102 is not connected to the sound outlet channel 1142, and dust and other impurities from the outside cannot enter the mounting slot 1101 through the sound outlet hole 1102, and cannot enter the front sound cavity 1501 through the sound outlet channel 1142, thereby ensuring the sound quality of the electric energy sound converter 150, improving the dustproof effect of the electronic device 100, and improving the sealing of the electronic device 100.

[0186] In addition, the sound emitted by the electric energy sound converter 150 is transmitted to the installation slot 1101 through the sound outlet channel 1142 connected to the front sound cavity 1501. Since the sound outlet hole 1102 is blocked from opening toward the installation slot 1101, the sound can only pass through the opening of the installation slot 1101 (i.e. Figure 1 The receiver hole 1103 shown is transmitted to the external environment of the electronic device 100.

[0187] At this time, the electronic device 100 is in the handset mode, that is, the electric energy sound converter 150 is used as the handset of the electronic device 100. When the user holds the electronic device 100, the user's ear is close to the mounting slot 1101, and the sound can only be heard from the receiving hole 1103, which effectively prevents the sound generated by the electric energy sound converter 150 from being transmitted to the outside of the housing 110 through the sound outlet 1102, that is, the sound generated by the electric energy sound converter 150 is prevented from leaking to the external environment through the sound outlet 1102, thereby improving the sound leakage problem of the electronic device 100 and ensuring the user's personal privacy.

[0188] In some other embodiments, when the switch assembly 160 is in the closed state, the switch assembly 160 can also block the opening of the sound outlet channel 1142 toward the mounting slot 1102, so as to block between the sound outlet channel 1142 and the mounting slot 1101, thereby blocking the sound outlet hole 1102 and the sound outlet channel 1142. At this time, the sound outlet channel 1142 is not connected to the mounting slot 1101, and dust and other impurities from the outside can enter the mounting slot 1101 through the sound outlet hole 1102, but cannot enter the front sound cavity 1501 through the sound outlet channel 1142, which can also ensure the sound quality of the electric energy sound converter 150, improve the dustproof effect of the electronic device 100, and improve the sealing of the electronic device 100. In addition, the sound emitted by the electric energy sound converter 150 cannot be transmitted to the mounting slot 1101 through the sound outlet channel 1142, and at this time, no sound will be transmitted to the external environment through the opening of the mounting slot 1101 and the sound outlet hole 1102.

[0189] Please also read Figure 8 , Figure 8 yes Figure 6 The structure shown is a schematic diagram of the switch assembly 160 in the open state after being cut along II-II. Figure 8 The solid line with arrows is the propagation path of the sound.

[0190] When the switch assembly 160 is in the open state, the switch assembly 160 does not block the opening of the sound outlet hole 1102 toward the mounting groove 1101, so that the sound outlet hole 1102 is connected to the mounting groove 1101, and further the sound outlet hole 1102 is connected to the sound outlet channel 1142. At this time, the sound emitted by the electric energy sound converter 150 is transmitted to the mounting groove 1501 through the sound outlet channel 1501 connected to the front sound cavity 1501, and then through the opening of the mounting groove 1101 (i.e. Figure 1 The receiver hole 1103) and the sound outlet hole 1102 are shown to transmit the external environment of the electronic device 100.

[0191] At this time, the electronic device 100 is in the external speaker mode, that is, the electric energy sound transducer 150 is used as a speaker of the electronic device 100. When the user uses the electronic device 100 by hand, the user can hear the sound from the receiving hole 1103 and the sound outlet hole 1102 at the same time, which is not only conducive to expanding the sound output area of ​​the electric energy sound transducer 150 and improving the sound loudness of the electric energy sound transducer 150, but also conducive to optimizing the stereo effect.

In some other embodiments, the switch assembly 160 may not have mirror-symmetry, and the present application does not specifically limit the symmetry of the switch assembly 160.

[0194] The switch assembly 160 includes a driving mechanism 160a and a partition 20. The driving mechanism 160 drives the partition 20 to move between a first position and a second position so that the switch assembly 160 switches between a closed state and an open state. Exemplarily, when the partition 20 is in the first position, the switch assembly 160 is in a closed state. When the partition 20 is in the second position, the switch assembly 160 is in an open state.

[0195] The driving mechanism 160a includes a base 10, a fixed claw 30, a connecting plate 40 and a memory wire 50. The partition 20 is mounted on the base 10 and can move relative to the base 10.

The second left notch 104b is located between the chute 101 and the first left notch 103b, and penetrates the groove side wall of the chute 101 and the groove side wall of the first left notch 103b to connect the chute 101 and the first left notch 103b.

[0202] In addition, the base 10 may also be provided with a plurality of auxiliary notches to reduce the material cost of the base 10, reduce the weight of the base 10, and facilitate the lightweight design of the electronic device 100.

[0212] The separator 20 is a plate structure extending in the X-axis direction. In the present embodiment, the structure of the separator 20 is adapted to the structure of the slide groove 101. Specifically, the length of the separator 20 is L1 and the thickness is W1. Among them, L1 may be equal to L0, and W1 may be equal to W0, so that the separator 20 is limited in the slide groove 101 in both the X-axis direction and the Y-axis direction, and will not fall off from the slide groove 101 in the X-axis direction or the Y-axis direction. In some other embodiments, L1 may also be slightly larger or smaller than L0, and W1 may also be slightly larger or smaller than W0.

[0213] The separator 20 is provided with a second connecting portion 201. The second connecting portion 201 is located in the middle part of the separator 20. Exemplarily, the second connecting portion 201 is a notch. The opening of the second connecting portion 201 is located on the inner side of the separator 20. The second connecting portion 201 extends from the inner side of the separator 20 to the outer side, and penetrates the outer side of the separator 20. That is, the second connecting portion 201 penetrates the separator 20 along the thickness direction of the separator 20. In addition, the second connecting portion 201 also penetrates the reverse side of the separator 20. In some other embodiments, the second connecting portion 201 may not be a notch, but a through hole.

[0214] In one embodiment, the separator 20 includes two movable claws 21 and a main body 22. The two movable claws 21 are arranged at intervals along the X-axis direction. The main body 22 is connected between the two movable claws 21. That is, the two movable claws 21 are respectively connected to opposite sides of the main body 22. Specifically, the two movable claws 21 are respectively located at opposite ends of the separator 20. The movable claws 21 are made of conductive materials such as metal. Exemplarily, the two movable claws 21 are a first movable claw 21a and a second movable claw 21b, and the first movable claw 21a is located on the side of the second movable claw 22a facing the positive direction of the X-axis.

[0215] The main body 22 is located in the middle part of the separator 20. The main body 22 is provided with a second connecting portion 201. The main body 22 is made of a conductive material such as metal. Exemplarily, the main body 22 and the two movable claws 21 are integrally formed to ensure the overall strength of the separator 20. In some other embodiments, the main body 22 may also be made of a non-conductive material, or the main body 22 and the two movable claws 21 may be assembled to form an integrated structure, which is not specifically limited in the present application.

[0216] Please also read Figure 9a , Figure 9b , Fig.10a and Fig.10b , the separator 20 is installed in the slide groove 101, and can slide relative to the base 10 in the slide groove 101 along the Z axis direction. Exemplarily, the first position is located on the side of the second position facing the negative direction of the Z axis. The direction from the first position to the second position is the positive direction of the Z axis. The direction from the second position to the first position is the negative direction of the Z axis. Wherein, the distance between the first position and the second position is h.

[0217] In addition, the separator 20 is also fixedly connected to the two reset members 11, so as to move along the Z-axis direction under the drive of the two reset members 11. Specifically, the main body 22 of the separator 20 is fixedly connected to the two reset members 11. Among them, one end of the main body 22 close to the first movable claw 21a is fixedly connected to the first reset member 11a, and one end of the main body 22 close to the second movable claw 21b is fixedly connected to the second reset member 11b.

[0218] In this embodiment, the two reset members 11 are tension springs, and the elastic force direction of the two reset members 11 is the Z-axis direction. The two reset members 11 can drive the separator 20 to move from the second position to the first position. At this time, the two reset members 11 are connected between the base 10 and the separator 20, and can limit the separator 20 in the Z-axis direction, limit the moving distance of the separator 20 relative to the base 10 in the Z-axis direction, ensure the connection stability between the separator 20 and the base 10, improve the connection stability between the separator 20 and the driving mechanism 160a, and ensure the overall structural stability of the switch assembly 160. In some other embodiments, the reset member 11 can also be an elastic glue or other elastic member.

[0219] It should be noted that, in some other embodiments, the number of the reset members 11 may be one, three or more than four, and each reset member 11 is connected between the base 10 and the partition 20. In this case, the number of the mounting holes 108 of the base 10 is equal to or greater than the number of the reset members 11, and the partition 20 can also move relative to the base 10 along the negative direction of the Z axis under the drive of the reset members 11.

[0220] When the partition 20 is in the first position (eg Figure 9a and Figure 9b As shown), the switch assembly 160 is in a closed state, the first connecting portion 102 of the base 10 and the second connecting portion 202 of the partition 20 are staggered, and the first reset member 11a and the second reset member 11b are both in a free state or a compressed state.

[0221] It should be noted that the first connecting portion 102 of the base 10 and the second connecting portion 202 of the separator 20 are staggered, which means that the orthographic projection of the second connecting portion 202 on the base 10 does not overlap with the first connecting portion 102, or the orthographic projection of the first connecting portion 102 on the separator 20 does not overlap with the second connecting portion 202. In other words, the separator 20 completely blocks the first connecting portion 102, and the second connecting portion 202 is not connected to the first connecting portion 101.

[0222] When the partition 20 is in the second position (eg Fig.10a and Fig.10b As shown), the switch assembly 20 is in an open state, the first connecting portion 102 of the base 10 and the second connecting portion 202 of the partition 20 are enclosed to form a connecting hole 161, and the first restoring member 11a and the second restoring member 11b are both in a stretched state.

[0224] The two fixing claws 30 are both mounted on the base 10 and are arranged at intervals along the X-axis direction. Specifically, the two fixing claws 30 are respectively mounted on the two first notches 103 (such as Fig.11a As shown). The two fixing claws 30 are respectively mounted on the bottom walls of the grooves of the two first notches 103. Exemplarily, the fixing claws 30 are mounted on the bottom walls of the grooves of the second notch by bonding. At this time, the two fixing claws 30 are respectively located on opposite sides of the separator 20. In addition, the thickness of the fixing claws 30 is less than or equal to the depth of the first notch 103. That is, the outer side surface of the fixing claws 30 does not exceed the outer side surface of the base 10, that is, the fixing claws 30 completely share the thickness space of the base 10, which can reduce the thickness dimension of the switch assembly 160.

[0225] In this embodiment, the two fixed claws 30 are respectively the first fixed claw 30a and the second fixed claw 30b, and the first fixed claw 30a is located on the side of the second fixed claw 30b facing the positive direction of the X-axis. Specifically, the first fixed claw 30a is installed on the first right notch 103a, and is located on the side of the partition 20 close to the first movable claw 21a. The second fixed claw 30b is installed on the first left notch 103b, and is located on the side of the partition 20 close to the second movable claw 21. At this time, the first fixed claw 30a is closer to the first movable claw 21a than the second fixed claw 30b, and the second fixed claw 30b is closer to the second movable claw 21b than the first fixed claw 30a. Among them, the first fixed claw 30a is installed on the bottom wall of the groove of the first right notch 103a, and the second fixed claw 30b is installed on the bottom wall of the groove of the first left notch 103b.

[0226] The two connecting plates 40 are both mounted on the base 10 and arranged at intervals along the X-axis direction.

In this embodiment, the two connecting plates 40 are respectively a first connecting plate 40a and a second connecting plate 40b, and the first connecting plate 40a is located on the side of the second connecting plate 40b facing the positive direction of the X-axis. Part of the first connecting plate 40a is electrically connected to the first movable claw 21a and the first fixed claw 30a, and part of the first connecting plate 40a is electrically connected to the circuit board 130, so as to realize the first movable claw 21a and the first fixed claw 30a and the processor 140 (such as Figure 2 Part of the second connecting plate 40b is electrically connected to the second movable claw 21b and the second fixed claw 30b, and part of the second connecting plate 40b is electrically connected to the circuit board 130 to achieve electrical connection between the second movable claw 21b and the second fixed claw 30b and the processor 140.

[0227] The first connecting plate 40a includes a first sub-connecting plate 41a, a second sub-connecting plate 42a and a third sub-connecting plate 43a which are connected in sequence. Part of the first sub-connecting plate 41a is located in the slide groove 101 and contacts the first movable claw 21a, part of the first sub-connecting plate 41a is located in the second right notch 104a, and part of the first sub-connecting plate 41a is located in the first right notch 103a and contacts the first fixed claw 30a. Among them, the first sub-connecting plate 41a contacts the outer side surface of the first movable claw 21a and the first fixed claw 30a. At this time, the outer side surface of the first sub-connecting plate 41a does not exceed the outer side surface of the base 10, that is, the first sub-connecting plate 41a completely shares the thickness space of the base 10, which can reduce the thickness dimension of the switch assembly 160.

[0228] The second sub-connection plate 42a is located on the side close to the back surface of the base 10. The third sub-connection plate 43a is located on the side close to the inner side of the base 10. The third sub-connection plate 43a extends from the first mounting portion 1141a of the middle plate 114 into the second right notch 1143a, and is connected to the accommodating cavity (i.e., the aforementioned rear sound cavity, not shown) through the first contact pin 134 (such as Figure 2 As shown in the figure, the circuit board 130 is electrically connected to realize the electrical connection between the first connection board 40a and the processor 140.

[0229] Exemplarily, the first sub-connection board 41a may be a rigid circuit board, and the second sub-connection board 42a and the third sub-connection board 43a may be flexible circuit boards, that is, the first connection board 40a is a rigid-flexible board. In some other embodiments, the first connection board 40a may also be a flexible circuit board or a rigid circuit board, and the present application does not specifically limit the specific type of the first connection board 40a.

[0230] The structure of the second connecting plate 40b is the same as that of the first connecting plate 40a. The second connecting plate 40b includes a first sub-connecting plate 41b, a second sub-connecting plate 42b and a third sub-connecting plate 43b connected in sequence. Part of the first sub-connecting plate 41b is located in the slide groove 101 and contacts the second movable claw 21b, part of the first sub-connecting plate 41b is located in the second left notch 104b, and part of the first sub-connecting plate 41b is located in the first left notch 103b and contacts the second fixed claw 30b. Among them, the first sub-connecting plate 41b contacts the outer side surface of the second movable claw 21b and the second fixed claw 30b. At this time, the outer side surface of the first sub-connecting plate 41b does not exceed the outer side surface of the base 10, that is, the first sub-connecting plate 41b completely shares the thickness space of the base 10, which can reduce the thickness dimension of the switch assembly 160.

[0231] The second sub-connection plate 42b is located on the side close to the back surface of the base 10. The third sub-connection plate 43b is located on the side close to the inner side of the base 10. The third sub-connection plate 43b extends from the second mounting portion 1141b of the middle plate 114 into the second left notch 1143b, and is connected to the second contact pin 135 (such as Figure 2 As shown) the circuit board 130 is electrically connected to achieve electrical connection with the processor 140.

[0232] Exemplarily, the first sub-connection board 41b may be a rigid circuit board, and the second sub-connection board 42b and the third sub-connection board 43b may be flexible circuit boards, that is, the first connection board 40b is a rigid-flexible board. In some other embodiments, the second connection board 40b may also be a flexible circuit board or a rigid circuit board, and the present application does not specifically limit the specific type of the second connection board 40.

[0233] See also Figure 6 and Figure 7 The electronic device 100 also includes a sealant 170. There are two sealants 170, and the two sealants 170 seal the two mounting parts 1141 respectively. Specifically, the two sealants 170 are a first sealant 170a and a second sealant 170b. The first sealant 170a seals the first mounting part 1141a of the middle plate 114, and the second sealant 170b seals the second mounting part 1141b of the middle plate 114, so as to block the front sound cavity 1501 and the rear sound cavity of the electric energy converter 150, prevent the front sound cavity 1501 and the rear sound cavity (not shown) of the electric energy converter 150 from being connected, and ensure the sound quality of the electric energy converter 150.

[0234] See also Figure 9a The two memory wires 50 are respectively a first memory wire 50a and a second memory wire 50b. One end of the first memory wire 50a is fixed to the first fixed claw 30a, and the other end is fixed to the second movable claw 21b. One end of the second memory wire 50b is fixed to the second fixed claw 30b, and the other end is fixed to the first movable claw 21a.

[0235] The two memory metal wires 50 are both made of shape memory alloy (SMA) material. Shape memory alloy is a general term for metals with shape memory effect, such as nickel-titanium alloys such as titanium-nickel-copper, titanium-nickel-iron or titanium-nickel-chromium, or copper-nickel alloys, or copper-aluminum alloys, or copper-zinc alloys, or iron alloys, etc.

[0236] It should be noted that, generally, when a metal material is subjected to an external force, the first thing that occurs is elastic deformation. If the external force is removed at this time, the metal will return to its original shape. If the external force continues to increase, when the metal reaches its own yield point, plastic deformation will occur. After the external force is eliminated, permanent deformation will remain, and the shape will not recover even if heated. Shape memory alloy is an alloy material that can completely eliminate the deformation that occurs at a lower temperature after heating and restore its original shape before deformation. The basic principle of the working of shape memory alloy material is to heat the material to a certain critical temperature for shape memory heat treatment (training), and cause it to undergo a certain deformation. After cooling to form a martensite phase, when it is heated again to above the critical temperature, the low-temperature martensite phase reverses to a high-temperature austenite phase (i.e., a reverse transformation occurs), thereby restoring to the state memorized before deformation.

[0237] In the embodiment of the present application, when the memory wire 50 is powered on, the heat generated by the current flowing through the memory wire 50 causes the temperature of the memory wire 50 to rise, realizing the reverse phase transformation from the low-temperature martensite phase to the high-temperature austenite phase, and recovering to the memory before deformation, thereby causing the memory wire 50 to shrink. The length change caused by the shrinkage of the memory wire 50 is essentially caused by the transformation of the material crystal phase structure, that is, the transformation between martensite and austenite. The gravitational force between microscopic particles due to the change in crystal structure (that is, the transformation of the gap between atoms) makes the pulling force of the memory wire 50 larger when it shrinks macroscopically. Therefore, the shrinkage of the memory wire 50 can drive a heavier load, that is, it can achieve a large load, so the drive mechanism 160a can achieve a larger driving force with a smaller size. The small-sized drive mechanism 160a is conducive to reducing the space occupied inside the electronic device 100 and realizing the miniaturized design of the electronic device 100.

[0238] Processor 140 (eg Figure 2 As shown in FIG. 1 , the first fixed claw 30a and the second movable claw 21b can be powered on through the circuit board 130 and the first connecting plate 40a, and the second fixed claw 30b and the first movable claw 21a can be powered on through the circuit board 130 and the second connecting plate 40b. At this time, the first memory wire 50a and the second memory wire 50b are both powered on, and the first memory wire 50a and the second memory wire 50b shrink due to the increase in temperature. The length of the first memory wire 50a and the second memory wire 50b is shortened, which will generate a pulling force along the positive direction of the Z axis on the separator 20, driving the separator 20 to move in the positive direction of the Z axis relative to the base 10 in the slide groove 101. At this time, the two reset members 11 in the free state or the compressed state will both be elastically deformed and elongated under the drive of the separator 20.

[0239] The processor 140 cuts off the power to the first fixed claw 30a and the second movable claw 21b via the circuit board 130 and the first connecting plate 40a, and cuts off the power to the second fixed claw 30b and the first movable claw 21a via the circuit board 130 and the second connecting plate 40b. At this time, the first memory wire 50a and the second memory wire 50b are both cut off, that is, there is no current on the first memory wire 50a and the second memory wire 50b, and the first memory wire 50a and the second memory wire 50b will not shrink due to the increase in temperature.

[0240] At this time, the first memory metal wire 50a and the second memory metal wire 50b can be stretched and deformed under the action of external force and their lengths can be extended. Exemplarily, the separator 20 can move along the negative direction of the Z axis under the action of external force, and the separator 20 can generate a pulling force along the negative direction of the Z axis on the first memory metal wire 50a and the second memory metal wire 50b, so that the first memory metal wire 50a and the second memory metal wire 50b are stretched and deformed and their lengths can be extended.

[0241] In this embodiment, the first restoring member 11a and the second restoring member 11b in the stretched state will return to their original shape and shorten in length. The first restoring member 11a and the second restoring member 11b will apply a pulling force along the negative direction of the Z axis to the separator 20, that is, the first restoring member 11a and the second restoring member 11b will drive the separator 20 to move along the negative direction of the Z axis, so that the first memory metal wire 50a and the second memory metal wire 50b are stretched and deformed and their length is extended under the drive of the separator 20.

[0242] It should be noted that when the memory wire 50 is powered on, current will flow through the memory wire 50, so the memory wire 50 will heat up and shorten in length. It is understandable that the shortening amplitude of the length of the memory wire 50 is positively correlated with the magnitude of the current carried, and the shortening amplitude of the length of the memory wire 50 is positively correlated with the distance that the separator 20 moves in the positive direction of the Z axis in the chute 101. The greater the current carried by the memory wire 50, the greater the shortening amplitude of the length of the memory wire 50, and the greater the distance that the separator 20 moves in the positive direction of the Z axis in the chute 101. The smaller the current carried by the memory wire 50, the smaller the shortening amplitude of the length of the memory wire 50, and the smaller the distance that the separator 20 moves in the positive direction of the Z axis in the chute 101.

[0243] Next, taking the case where the original length of the reset member 11 is l0, the current value carried by the memory wire 50 is I, and the length of the memory wire 50 is L2 as an example, the switch assembly 160 in different states is described.

[0244] Please also read Figure 7 and Figure 8 In this embodiment, the first connecting portion 102 of the base 10 is connected to the sound outlet channel 1142 , and the partition 20 is equivalent to the gate of the switch component 160 to control whether the first connecting portion 102 is connected to the sound outlet hole 1102 .

[0245] When the separator 20 is located at the first position, the two memory metal wires 50 are both in a power-off state, the lengths of the two memory metal wires 50 are both L3, and the lengths of the two reset elements 11 are both l0, wherein L3>L2.

[0246] Processor 140 (eg Figure 6 As shown in the figure, the two movable claws 21 and the two fixed claws 30 can be powered through the circuit board 130 and the two connecting plates 40, so that the two memory metal wires 50 are both charged with a current of magnitude I. The two memory metal wires 50 are heated and shortened under the action of the current, thereby driving the partition 20 to move relative to the base 10 along the positive direction of the Z axis in the slide groove 101. At this time, the two reset members 11 are elastically deformed and extended in length under the drive of the partition 20.

[0247] When the length of the two memory wires 50 is shortened to L2, the separator 20 just moves h along the positive direction of the Z axis, the separator 20 is in the second position, and the lengths of the two reset members 11 are both l1. Among them, l1>l0, and l1-l0=h. At this time, the switch assembly 160 is in the open state, the second connecting portion 201 of the separator 20 and the first connecting portion 102 of the base 10 are enclosed to form a connecting hole 161, the sound outlet hole 1102 is connected to the sound outlet channel 1142, the electric energy sound converter 150 can emit sound through the sound outlet hole 1102 and the receiving hole 1103 at the same time, and the electronic device 100 is in the external speaker mode.

[0248] It can be understood that when both memory metal wires 50 carry a current of magnitude I, the second connecting portion 201 of the separator 20 and the first connecting portion 102 of the base 10 enclose a connecting hole 161 with the largest volume. In some other embodiments, when both memory metal wires 50 carry a current slightly less than I, the second connecting portion 201 of the separator 20 and the first connecting portion 102 of the base 10 can also enclose a connecting hole 161 with a smaller volume. At this time, the switch assembly 160 is also in the open state, and the electronic device 100 is still in the external speaker mode. Due to the small volume of the connecting hole 161, the external speaker loudness of the electronic device 100 will be relatively reduced.

[0249] When the separator 20 is located at the second position, the two memory metal wires 50 both carry a current of magnitude I, the lengths of the two memory metal wires 50 are both L2, and the lengths of the two reset elements 11 are both l1.

[0250] The processor 140 can stop powering the two connecting plates 40 through the circuit board 130, and then stop powering the two movable claws 21 and the two fixed claws 30, so that the two memory wires 50 are powered off. The two memory wires 50 will not shrink without the action of current. The two reset members 11 in the stretched state will return to their original shape and shorten in length, thereby driving the separator 20 to move relative to the base 10 in the slide groove 101 along the negative direction of the Z axis, and the two memory wires 50 will be stretched and deformed by the separator 20 and extend in length.

[0251] When the length of the two reset members 11 is shortened to l0, the partition 20 just moves h along the negative direction of the Z axis, the partition 20 is in the first position, and the length of the two memory wires 50 is extended to L3. At this time, the switch assembly 160 is in the closed state, the partition 20 blocks the sound outlet channel 1142 and the sound outlet hole 1102, the electric energy sound converter 150 can only emit sound through the receiver hole 1103, and the electronic device 100 is in the handset mode.

[0252] It is understandable that when both memory metal wires 50 carry a current of 0, the separator 20 completely blocks the first connecting portion 102 of the base 10. In some other embodiments, when both memory metal wires 50 carry a current greater than 0, the separator 20 may not completely block the first connecting portion 102 of the base 10. At this time, the second connecting portion 201 of the separator 20 and the first connecting portion 102 of the base 10 can be enclosed to form a smaller connecting hole 161. At this time, the electric energy sound converter 150 can also emit sound through the sound outlet 1103, which can not only avoid a large amount of leakage of the electronic device 100, but also increase the loudness of the earpiece of the electronic device 100.

[0253] In some other embodiments, the first connecting portion 102 of the base 10 may also be connected to the sound outlet hole 1102. At this time, the partition 20 is equivalent to the gate of the switch assembly 160 to control whether the first connecting portion 102 is connected to the sound outlet channel 1142. When the partition 20 is in the first position, the first connecting portion 102 of the base 10 and the second connecting portion 202 of the partition 20 are staggered, and the partition 20 blocks the first connecting portion 102 and the sound outlet channel 1142 to block the sound outlet hole 1102 and the sound outlet channel 1142. When the partition 20 is in the second position, the first connecting portion 102 and the second connecting portion 201 enclose to form a connecting hole 161, and the connecting hole 161 is connected to the sound outlet channel 1142 and the sound outlet hole 1102, so that the sound outlet hole 1102 and the sound outlet channel 1142 are connected.

[0254] In the electronic device 100 shown in the present embodiment, two memory metal wires 50 are used to control the movement of the partition 20 relative to the base 10 along the Z-axis direction to realize the connectivity between the sound channel 1142 and the sound hole 1102. When the sound hole 1102 is not in use, the sound hole 1102 can be closed to prevent external dust and other impurities from entering the front sound cavity 1501 through the sound hole 1102 and affecting the sound quality, thereby improving the dustproof effect of the electronic device 100 and ensuring the sealing of the electronic device 100.

[0255] In addition, the processor 140 is used to adjust the current carried by the two memory metal wires 50 to adjust the movement distance of the partition 20 in the slide groove 101 relative to the base 10 along the Z-axis direction, which can not only realize the active adjustment of the earpiece loudness and leakage volume of the electronic device 100, but also realize the adjustment of the external speaker loudness of the electronic device 100.

[0256] See also Fig.15 and Fig.16 , Fig.15 is a structural diagram of a second electronic device 100 provided in an embodiment of the present application when the switch component 160 is in a closed state, Fig.16It is a structural schematic diagram of the switch component 160 in the second electronic device 100 provided in an embodiment of the present application when it is in an open state.

[0257] In this embodiment, the driving mechanism 160a includes a base 10, a fixed claw 30, a connecting plate 40 and a memory metal wire 50. The separator 20 is mounted on the base 10 and can move relative to the base 10. Among them, the separator 20 includes two movable claws 21, and the two movable claws 21 are respectively located at opposite ends of the separator 20. There are two fixed claws 30, and the two fixed claws 30 are respectively mounted at opposite ends of the base 10 and are respectively located on opposite sides of the separator 20. There are two connecting plates 40, and each connecting plate 40 is connected to a movable claw 21 and a fixed claw 30. There are two memory metal wires 50, and one end of each memory metal wire 50 is connected to a fixed claw 30, and the other end is connected to a movable claw 21.

[0258] Please also read Fig.17 , Fig.17 yes Fig.15 A schematic structural diagram of the base 10 in the switch assembly 160 is shown.

[0259] The difference between the base 10 in the switch assembly 160 shown in the embodiment of the present application and the base 10 in the switch assembly 160 shown in the first embodiment described above is that the first connecting portion 102 is a through hole. The first connecting portion 102 is located in the middle part of the base 10. Specifically, the opening of the first connecting portion 102 is located on the inner side of the base 10. The through hole 105 extends from the inner side of the base 10 to the groove side wall of the slide groove 101, and penetrates the groove side wall of the slide groove 101 to connect the slide groove 101. Exemplarily, there are four first connecting portions 102, and the four first connecting portions 102 are arranged at intervals along the X-axis direction. Among them, the diameter of the first connecting portion 102 is d0, and the distance between adjacent first connecting portions 102 is D0. It should be understood that the shape of the first connecting portion 102 is not limited to Fig.16 The circle shown may also be a square or a special shape. In some other embodiments, the first connecting portion 102 may also have one, two, three or more than five. The present application does not specifically limit the number of the first connecting portion 102. Alternatively, the first connecting portion 102 may also be a notch.

[0260] In addition, the base 10 is also provided with a mounting hole 108. The opening of the mounting hole 108 is located on the side wall of the slide groove 101. The mounting hole 108 extends from the side wall of the slide groove 101 in a direction away from the slide groove 101. That is, the side wall of the slide groove 101 is partially recessed to form the mounting hole 108. There are two mounting holes 108, and the two mounting holes 108 are arranged at intervals along the X-axis direction. Among them, the two mounting holes 108 are respectively a first mounting hole (not shown) and a second mounting hole 108b. The opening of the first mounting hole is located on the side wall of the slide groove 101 facing the first right notch 104a, and the opening of the second mounting hole 108b is located on the side wall of the slide groove 101 facing the first left notch 104b. It should be noted that the shape of the mounting hole 108 is not limited to Fig.11b The circle shown may also be a square or a special shape.

[0261] See also Fig.18 , Fig.18 yes Fig.15 A schematic diagram of the assembly structure of the base 10 and the reset member 11 in the switch assembly 160 is shown.

[0262] In addition, the driving mechanism 160a further includes a reset member 11. There are two reset members 11, both of which are mounted on the base 10 and arranged at intervals along the X-axis direction. Specifically, the two reset members 11 are respectively mounted on the two mounting holes 108. The two reset members 11 are respectively mounted on the hole walls of the two mounting holes 108, and part of the reset members 11 is exposed relative to the groove side wall of the slide groove 101.

[0263] In this embodiment, the two reset members 11 are respectively a first reset member 11a and a second reset member 11b, and the first reset member 11a is located on the side of the second reset member 11b facing the positive direction of the X-axis. Specifically, the first reset member 11a is installed in the first mounting hole 108a, and the second reset member 11b is installed in the second mounting hole 108b. Among them, one end of the first reset member 11a is fixedly connected to the hole wall of the first mounting hole 108, and the other end is exposed relative to the groove side wall of the slide groove 101. One end of the second reset member 11b is fixedly connected to the hole wall of the second mounting hole 108, and the other end is exposed relative to the groove side wall of the slide groove 101.

[0264] Please also read Fig.19 , Fig.19 yes Fig.15 A schematic structural diagram of the partition 20 in the switch assembly 160 is shown.

[0265] In this embodiment, the width W1 of the separator 20 may be equal to the width W0 of the slide groove 101, so that the separator 20 is limited in the slide groove 101 in the Y-axis direction to prevent the separator 20 from falling out of the slide groove 101 along the Y-axis direction. Among them, the length L1 of the separator 20 is less than the length L0 of the slide groove 101, so that the separator 20 can slide in the slide groove 101 relative to the base 10 along the X-axis direction. Exemplarily, L0=L1+D0. In some other embodiments, L0 may also be greater than L1+D0. The length of the slide groove 101 is not specifically limited in this application, as long as the separator 20 can slide in the slide groove 101 along the X-axis direction for a distance greater than D0.

[0266] The second connecting portion 201 of the separator 20 is a through hole. The second connecting portion 202 is located in the middle part of the separator 20. The opening of the second connecting portion 202 is located on the inner side of the separator 20. The second connecting portion 202 extends from the inner side of the separator 20 to the outer side, and passes through the outer side of the separator 20. That is, the second connecting portion 202 passes through the separator 20 along the thickness direction of the separator 20. Among them, the second connecting portion 202 is located in the main body 22 of the separator 20. Exemplarily, there are four second connecting portions 202, and the four second connecting portions 202 are arranged at intervals along the X-axis direction. Among them, the diameter of the second connecting portion 202 is d1, and the distance between adjacent second connecting portions 202 is D1, d1=d0, D1=D0, D1≥2d0. In some other embodiments, there may be one, two, three or more second connecting portions 202. The present application does not specifically limit the number of second connecting portions 202 of the separator 20. Alternatively, the second connecting hole 202 may not be a notch but a through hole.

[0267] See also Fig.15 and Fig.16 , the separator 20 is installed in the slide slot 101 and can move in the slide slot 101 along the X-axis direction. Exemplarily, the first position is located on the side of the second position facing the negative direction of the X-axis. The direction from the first position to the second position is along the positive direction of the X-axis. The direction from the second position to the first position is along the negative direction of the X-axis. Wherein, the distance between the first position and the second position is d.

[0268] In this embodiment, the separator 20 is also fixedly connected to the two reset members 11, so as to move along the X-axis direction when the two reset members 11 are driven. Specifically, the two movable claws 21 of the separator 20 are respectively fixedly connected to the two reset members 11. Among them, the end of the first movable claw 21a away from the main body 22 is fixedly connected to the first reset member 11a, and the end of the second movable claw 21b away from the main body 22 is fixedly connected to the second reset member 11b. That is, the first reset member 11a is connected between the base 10 and the first movable claw 21a, and the second reset member 11b is connected between the base 10 and the second movable claw 21b.

[0269] In this embodiment, both reset members 11 are compression springs, and the elastic force directions of both reset members 11 are in the X-axis direction. The first reset member 11a can drive the separator 20 to move from the second position to the first position, and the second reset member 11b can drive the separator 20 to move from the first position to the second position. At this time, both reset members 11 are connected between the base 10 and the separator 20, and can limit the separator 20 in the X-axis direction, limit the moving distance of the separator 20 relative to the base 10 in the X-axis direction, ensure the connection stability between the separator 20 and the base 10, improve the connection stability between the separator 20 and the driving mechanism 160a, and ensure the overall structural stability of the switch assembly 160. In some other embodiments, the reset member 11 can also be an elastic glue or other elastic member.

[0270] It should be noted that, in some other embodiments, the number of the reset members 11 may be more than three, and each reset member 11 is connected between the base 10 and the partition 20. In this case, the number of the mounting holes 108 of the base 10 is equal to or greater than the number of the reset members 11, and the partition 20 can also move relative to the base 10 along the X-axis direction under the drive of the reset members 11.

[0271] When the partition 20 is in the first position (eg Fig.14 As shown), the switch assembly 160 is in a closed state, the first connecting portion 102 of the base 10 and the second connecting portion 202 of the partition 20 are staggered, the first reset member 11a is in a free state, and the second reset member 11b is in a compressed state.

[0272] When the partition 20 is in the second position (eg Fig.15 As shown), the switch assembly 160 is in an open state, the second connecting portion 202 of the partition 20 is connected one by one with the first connecting portion 102 of the base 10, the first return member 11a is in a compressed state, and the second return member 11b is in a free state.

[0273] In this embodiment, one end of the first memory wire 50a is fixed to the first fixed claw 30, and the other end is fixed to the first movable claw 21. One end of the second memory wire 50b is fixed to the second fixed claw 30, and the other end is fixed to the second movable claw 21.

[0274] Processor 140 ( Figure 2As shown in FIG. 1 , the first fixed claw 30a and the first movable claw 21a can be powered on through the circuit board 130 and the first connecting plate 40a, and the second fixed claw 30b and the second movable claw 21b can be powered off through the circuit board 130 and the second connecting plate 40b. At this time, the first memory metal wire 50a is powered on, and the second memory metal wire 50b is powered off. The first memory metal wire 50a shrinks due to the increase in temperature. There is no current on the second memory metal wire 50b, and it will not shrink due to the increase in temperature. The first memory metal wire 50a will generate a pulling force along the positive direction of the X axis on the partition 20, driving the partition 20 to move relative to the base 10 in the slide groove 101 along the positive direction of the X axis. At this time, the partition 20 will generate a pulling force along the positive direction of the X axis on the second memory metal wire 50b, so that the second memory metal wire 50b is stretched and deformed and its length is extended.

[0275] In addition, the second restoring member 11b in the compressed state will return to its original shape and lengthen, and the second restoring member 11b will apply a thrust along the positive direction of the X-axis to the partition 20, pushing the partition 20 to move along the positive direction of the X-axis. At this time, the first restoring member 11a will be elastically deformed and shortened under the push of the partition 20.

[0276] The processor 140 cuts off the power to the first fixed claw 30a and the first movable claw 21a through the circuit board 130 and the first connecting plate 40a, and supplies power to the second fixed claw 30b and the second movable claw 21b through the circuit board 130 and the second connecting plate 40b. At this time, the first memory wire 50a is powered off, and the second memory wire 50b is powered on. There is no current on the first memory wire 50a, and it will not shrink due to the increase in temperature. The second memory wire 50b is shortened due to the increase in temperature. The second memory wire 50b will generate a pulling force along the negative direction of the X axis on the separator 20, driving the separator 20 to move in the negative direction of the X axis relative to the base 10 in the slide groove 101. At this time, the separator 20 will generate a pulling force along the negative direction of the X axis on the first memory wire 50a, so that the first memory wire 50a is stretched and deformed and the length is extended.

[0277] In addition, the first restoring member 11a in the compressed state will return to its original shape and lengthen, and the first restoring member 11a will apply a thrust along the negative direction of the X-axis to the partition 20, pushing the partition 20 to move along the negative direction of the X-axis. At this time, the second restoring member 11b will be elastically deformed and shortened under the push of the partition 20.

[0278] In some other embodiments, the first reset member 11a and the second reset member 11b may also be tension springs, and the elastic force directions of the two reset members 11 are both in the X-axis direction. In this case, the first reset member 11a is connected between the base 10 and the second movable claw 21b, and the second reset member 11b is connected between the base 10 and the first movable claw 21a. When the partition 20 is in the first position, the first reset member 11a is in a stretched state, and the second reset member 11b is in a free state. When the partition 20 is in the second position, the first reset member 11a is in a free state, and the second reset member 11b is in a stretched state.

[0279] At this time, when the first memory metal wire 50a is powered off, the first reset member 11a in the stretched state will return to its original shape and shorten in length, and the first reset member 11a will generate a pulling force along the negative direction of the X-axis on the separator 20, pulling the separator 20 to move from the second position to the first position. When the second memory metal wire 50b is powered off, the second reset member 11b in the stretched state will return to its original shape and shorten in length, and the second reset member 11b will generate a pulling force along the positive direction of the X-axis on the separator 20, pulling the separator 20 to move from the first position to the second position. Alternatively, the driving mechanism 160a may not include the first reset member 11a and the second reset member 11b, and the separator 20 may also move relative to the base 10 along the X-axis by powering on and off the two memory metal wires 50.

[0280] Next, taking the case where the original length of the reset member 11 is l0, the current value carried by the memory wire 50 is I, and the length of the memory wire 50 is L2 as an example, the switch assembly 160 in different states is described.

[0281] Please also read Figure 7 and Figure 8 When the separator 20 is in the first position, the first memory wire 50a is in the power-off state, the length of the first memory wire 50a is L4, the second memory wire 50b is in the power-on state, the second memory wire 50b carries a current of magnitude I, and the length of the second memory wire 50b is L2. Wherein, L4>L2, and L4-L2≥d. In addition, the length of the first reset member 11a is l0, and the length of the second reset member 11b is l2. Wherein, l2<l0, and l2-l0=d.

[0282] In one embodiment, the processor 140 (eg Figure 6(as shown) the first movable claw 21a and the first fixed claw 30a can be powered on through the circuit board 130 and the first connecting plate 40a, and the second movable claw 21b and the second fixed claw 30b can be powered off through the circuit board 130 and the second connecting plate 40a, so that the first memory metal wire 50a carries a current of magnitude I, and the second memory metal wire 50b does not carry current. The first memory metal wire 50a heats up and shortens in length under the action of the current, and the second memory metal wire 50b does not shrink without the action of the current. The first memory metal wire 50a drives the partition 20 to move relative to the base 10 along the positive direction of the X axis in the slide groove 101, and the second memory metal wire 50b is stretched and deformed and elongated in length under the drive of the partition 20. At this time, the second reset member 11b in the compressed state will return to its original shape and elongate in length, thereby pushing the partition 20 to move along the positive direction of the X axis, and the first reset member 11a is elastically deformed and shortened in length under the push of the partition 20.

[0283] When the length of the first memory metal wire 50a is restored to L2, the length of the second memory metal wire 50b is extended to L4, and the separator 20 just moves d along the positive direction of the X-axis. The separator 20 is located at the second position, the length of the first reset member 11a is l2, and the length of the second reset member 11b is l0.

[0284] At this time, the switch assembly 160 is in the open state, the second connecting part 202 of the partition 20 and the first connecting part 102 of the base 10 are connected one by one, the sound outlet hole 1102 is connected to the sound outlet channel 1142, the electric energy sound converter 150 can emit sound through the sound outlet hole 1102 and the receiving hole 1103 at the same time, and the electronic device 100 is in the external speaker mode.

[0285] It can be understood that when the first memory metal wire 50b carries a current of magnitude I and the second memory metal wire 50b does not carry a current, the second connecting portion 202 of the separator 20 and the first connecting portion 102 of the base 10 are completely connected in correspondence. In some other embodiments, when the first memory metal wire 50a carries a current slightly less than I and the second memory metal wire 50b carries a weak current, the second connecting portion 202 of the separator 20 and the first connecting portion 102 of the base 10 may not be completely connected in correspondence. At this time, the switch assembly 160 is also in the open state, and the electronic device 100 is still in the external speaker mode. Since the second connecting portion 202 of the separator 20 and the first connecting portion 102 of the base 10 are not completely connected in correspondence, the external speaker loudness of the electronic device 100 will be relatively reduced.

[0286] In another embodiment, the processor 140 can cut off the power to the first movable claw 21a and the first fixed claw 30a through the circuit board 130 and the first connecting plate 40a, and cut off the power to the second movable claw 21b and the second fixed claw 30b through the circuit board 130 and the second connecting plate 40b, so that the first memory wire 50a and the second memory wire 50b do not carry current. The first memory wire 50a and the second memory wire 50b will not shrink without the action of current. The second reset member 11b in the compressed state will return to its original shape and extend in length, thereby pushing the partition 20 to move along the positive direction of the X-axis, and the second memory wire 50b is stretched and deformed by the partition 20 and extends in length. In addition, the second reset member 11b is elastically deformed and shortened in length by the partition 20, and the length of the first memory wire 50a does not change.

[0287] When the length of the second restoring member 11b is restored to l0, the partition 20 just moves d along the positive direction of the X axis, the partition 20 is located at the second position, and the length of the second memory wire 50b is extended to L4. At this time, the length of the first restoring member 11a is shortened to l2, and the length of the first memory wire 50a is maintained at L4.

[0288] In the present embodiment, the processor 140 stops powering the two connecting plates 40 through the circuit board 130, and further stops powering the two movable claws 21 and the two fixed claws 30, so that the two memory metal wires 50 are de-energized. That is, there is no need to utilize electric energy, and only the elastic recovery effect of the reset member 11 is required to move the partition 20 from the first position to the second position, thereby saving the power consumption of the electronic device 100 and helping to improve the battery life of the electronic device 100.

[0289] When the separator 20 is in the second position, the first memory wire 50a is in the power-on state, the first memory wire 50a carries a current of magnitude I, and the length of the first memory wire 50a is L2, the second memory wire 50b is in the power-off state, and the length of the second memory wire 50b is L5. In addition, the length of the first reset member 11a is l2, and the length of the second reset member 11b is l0.

[0290] In one embodiment, the processor 140 can power off the first movable claw 21a and the first fixed claw 30a through the circuit board 130 and the first connecting plate 40a, and power on the second movable claw 21b and the second fixed claw 30b through the circuit board 130 and the second connecting plate 40a, so that the first memory wire 50a does not carry current, and the second memory wire 50b carries a current of magnitude I. The first memory wire 50a will not shrink without the action of current, the second memory wire 50b will heat up and shorten in length under the action of current, the second memory wire 50b drives the partition 20 to move relative to the base 10 in the slide groove 101 along the negative direction of the X axis, and the first memory wire 50a will be stretched and deformed and elongated in length under the drive of the partition 20. At this time, the first reset member 11a in the compressed state will return to its original shape and elongate in length, thereby pushing the partition 20 to move along the negative direction of the X axis, and the second reset member 11b will be elastically deformed and shortened in length under the push of the partition 20.

[0291] When the length of the second memory wire 50b is restored to L2, the length of the first memory wire 50a is extended to L4, the separator 20 just moves d along the negative direction of the X-axis, the separator 20 is located at the first position, the length of the first reset member 11a is l0, and the length of the second reset member 11b is l2.

[0292] At this time, the switch assembly 160 is in the closed state, the second connecting part 202 of the partition 20 and the first connecting part 102 of the base 10 are completely offset, the partition 20 blocks the sound outlet channel 1142 and the sound outlet hole 1102, the electric energy sound converter 150 can only make sound through the receiving hole 1103, and the electronic device 100 is in the handset mode.

[0293] It is understandable that when the first memory metal wire 50b carries no current and the second memory metal wire 50b carries a current of magnitude I, the second connecting portion 202 of the separator 20 and the first connecting portion 102 of the base 10 are completely staggered. In some other embodiments, when the first memory metal wire 50a carries a weak current and the second memory metal wire 50b carries a current value slightly less than I, the second connecting portion 202 of the separator 20 and the first connecting portion 102 of the base 10 may not be completely staggered, but partially connected. At this time, the electric energy sound converter 160 can also emit sound through the sound outlet 1103, which can not only avoid a large amount of leakage of the electronic device 100, but also increase the loudness of the earpiece of the electronic device 100.

[0294] In another embodiment, the processor 140 can cut off the power to the first movable claw 21a and the first fixed claw 30a through the circuit board 130 and the first connecting plate 40a, and cut off the power to the second movable claw 21b and the second fixed claw 30b through the circuit board 130 and the second connecting plate 40b, so that the first memory wire 50a and the second memory wire 50b do not carry current. The first memory wire 50a and the second memory wire 50b will not shrink without the action of current. The first reset member 11a in the compressed state will return to its original shape and lengthen, thereby pushing the partition 20 to move along the positive direction of the X-axis, and the first memory wire 50a will be stretched and deformed and elongated under the drive of the partition 20. In addition, the second reset member 11b is elastically deformed and shortened under the push of the partition 20, and the length of the second memory wire 50b does not change.

[0295] When the length of the first restoring member 11a is restored to l0, the separator 20 just moves d along the positive direction of the X axis, the separator 20 is located at the first position, and the length of the first memory wire 50a is extended to L4. At this time, the length of the second restoring member 11b is shortened to l2, and the length of the second memory wire 50a is maintained at L4.

[0296] In the present embodiment, the processor 140 stops powering the two connecting plates 40 through the circuit board 130, and further stops powering the two movable claws 21 and the two fixed claws 30, so that the two memory metal wires 50 are de-energized. That is, there is no need to utilize electric energy, and only the elastic recovery effect of the reset member 11 is required to move the partition 20 from the second position to the first position, thereby saving the power consumption of the electronic device 100 and helping to improve the battery life of the electronic device 100.

[0297] In the electronic device 100 shown in the present embodiment, the memory metal wire 50 and the reset member 11 are used to control the movement of the partition 20 relative to the base 10 along the X-axis direction to realize the connectivity between the sound channel 1142 and the sound hole 1102. When the sound hole 1102 is not in use, the sound hole 1102 can be closed to prevent external dust and other impurities from entering the front sound cavity 1501 through the sound hole 1102 and affecting the sound quality, thereby improving the dustproof effect of the electronic device 100 and ensuring the sealing of the electronic device 100.

[0298] In addition, the processor 140 is used to adjust the current carried by the two memory metal wires 50 to adjust the movement distance of the partition 20 in the slide groove 101 relative to the base 10 along the X-axis direction, which can not only realize the active adjustment of the earpiece loudness and leakage volume of the electronic device 100, but also realize the adjustment of the external speaker loudness of the electronic device 100.

[0300] In this embodiment, the driving mechanism 160a includes a base 10, a fixed claw 30, a connecting plate 40 and a memory wire 50. The separator 20 is mounted on the base 10 and can rotate relative to the base 10. The separator 20 includes a movable claw 21, and the movable claw 21 is located at one end of the separator 20. The fixed claw 30 is mounted on one end of the base 10 and is located on a side of the separator 20 away from the movable claw 21. The connecting plate 40 connects the separator 20 and the fixed claw 30. One end of the memory wire 50 is connected to the fixed claw 30, and the other end is connected to the movable claw 21.

[0302] The base 10 in the switch assembly 160 shown in the embodiment of the present application is different from the base 10 in the switch assembly 160 shown in the first embodiment described above in that the sliding groove 101 also penetrates the side of the base 10. The first notch 103 is located on one side of the sliding groove 101 and is arranged at intervals with the sliding groove 101. The second notch 104 connects the sliding groove 101 and the first notch 103. In addition, the base 10 is provided with a shaft hole 109. The shaft hole 109 is located on the side of the second notch 104 away from the first notch 103. The opening of the shaft hole 109 is located on the inner side of the base 10. The shaft hole 109 extends from the inner side of the base 10 to the groove side wall of the sliding groove 101 and penetrates the groove side wall of the sliding groove 101.

[0303] See also Figure 22b , Figure 22b yes Fig.22a The shown schematic diagram is a structural diagram of the base 10 at another angle.

[0304] The base 10 is also provided with a mounting hole 108. The opening of the mounting hole 108 is located at the bottom wall of the chute 101. The mounting hole 108 extends from the bottom wall of the chute 101 to the opposite side of the base 10. That is, the bottom wall of the chute 101 is partially recessed to form the mounting hole 108. The mounting hole 108 is exposed relative to the first right auxiliary notch 105a. It should be noted that the shape of the mounting hole 108 is not limited to Fig.11b The circle shown may also be a square or a special shape.

[0305] Please also read Fig.23 , Fig.23 yes Fig.20a A schematic diagram of the assembly structure of the base 10 and the reset member 11 in the switch assembly 160 is shown.

[0306] In addition, the driving mechanism 160a further includes a reset member 11, which is mounted on the base 10. Specifically, the reset member 11 is mounted on the mounting hole 108. The reset member 11 is mounted on the hole wall of the mounting hole 108, and a portion of the reset member 11 is exposed relative to the bottom wall of the slide slot 101.

[0307] Please also read Fig.24 , Fig.24 yes Fig.20a A schematic structural diagram of the partition 20 in the switch assembly 160 is shown.

[0308] In this embodiment, the width W1 of the separator 20 may be equal to the width W0 of the slide groove 101, so that the separator 20 is limited in the slide groove 101 in the Y-axis direction to prevent the separator 20 from falling out of the slide groove 101 along the Y-axis direction. The length L1 of the separator 20 is less than the length L0 of the slide groove 101, so that the separator 20 can rotate relative to the base 10 in the slide groove 101.

[0309] The separator 20 is provided with a shaft hole 203. The shaft hole 203 is located at one end of the separator 20. The opening of the shaft hole 203 is located at the inner side of the separator 20. The shaft hole 203 extends from the inner side of the separator 20 to the outer side, and penetrates the outer side of the separator 20. That is, the shaft hole 203 penetrates the separator 20 along the thickness direction of the separator 20. The separator 20 is made of a conductive material such as metal.

[0310] In one embodiment, the separator 20 includes a movable claw 21, a main body 22, and an auxiliary body 23 connected in sequence. The movable claw 21 and the auxiliary body 23 are arranged at intervals along the X-axis direction. The main body 22 is connected between the movable claw 21 and the auxiliary body 23. That is, the movable claw 21 and the auxiliary body 23 are respectively fixed to opposite sides of the main body 22. Specifically, the movable claw 21 and the auxiliary body 23 are respectively located at opposite ends of the separator 20. The movable claw 21 is located on the side of the auxiliary body 23 facing the positive direction of the X-axis. Among them, the main body 22 is provided with a shaft hole 203, and the shaft hole 203 is located on the side of the main body 22 close to the auxiliary body 23. Exemplarily, the movable claw 21, the main body 22 and the auxiliary body 23 are integrally formed to ensure the overall strength of the separator 20.

[0311] See also Fig.20a , Fig.20b , Fig.21a and Figure 21b , the separator 20 is rotationally connected to the base 10. In addition, the switch assembly 160 also includes a rotating shaft 60, which is installed in the rotating shaft hole 109 of the base 10 and the rotating shaft hole 203 of the separator 20. The separator 20 is installed in the slide groove 101, and the rotating connection with the base 10 is realized through the rotating shaft 60. At this time, the movable claw 21 is located at the end of the separator 20 away from the rotating shaft 60. Exemplarily, the direction from the first position to the second position is the counterclockwise direction (-ω direction shown in the figure). The direction from the second position to the first position is the clockwise direction (ω direction shown in the figure).

[0312] In addition, the separator 20 is also fixedly connected to the reset member 11, so as to rotate clockwise relative to the base 10 under the drive of the reset member 11. Specifically, the main body 22 of the separator 20 is fixedly connected to the reset member 11. Among them, one end of the main body 22 close to the movable claw 21 is fixedly connected to the reset member 11a.

[0313] In this embodiment, the reset member 11 is a tension spring. The reset member 11 is connected between the base 10 and the separator 20, and can drive the separator 20 to rotate in a clockwise direction relative to the base 10. At this time, the reset member 11 can limit the separator 20, limit the rotation angle of the separator 20 relative to the base 10, ensure the connection stability between the separator 20 and the base 10, improve the connection stability between the separator 20 and the driving mechanism 160a, and ensure the overall structural stability of the switch assembly 160. In some other embodiments, the reset member 11 can also be an elastic glue or other elastic member.

[0314] It should be noted that, in some other embodiments, the number of the reset members 11 may be two or more than three, and each reset member 11 is connected between the base 10 and the separator 20. In this case, the number of the mounting holes 108 of the base 10 is equal to or greater than the number of the reset members 11, and the separator 20 can also rotate clockwise relative to the base 10 under the drive of the reset members 11.

[0315] When the partition 20 is in the first position (eg Fig.20a and Fig.20b As shown), the switch assembly 100 is in a closed state, the partition 20 is folded relative to the base 10, the first connecting portion 102 of the base 10 and the second connecting portion 202 of the partition 20 are staggered, and the reset member 11 is in a free state or a compressed state.

[0316] When the partition 20 is in the second position (eg Fig.21a and Figure 21b As shown), the switch assembly 100 is in an open state, the partition 20 is open relative to the base 10, the first connecting portion 102 and the second connecting portion 201 are enclosed to form a connecting hole 161, and the reset member 11a is in a stretched state.

[0317] The fixing claw 30 and the connecting plate 40 are both installed on the base 10. Specifically, the fixing claw 30 is installed on the first notch 103, and the connecting plate 40 includes a first sub-connecting plate 41, a second sub-connecting plate 42 and a third sub-connecting plate 43 connected in sequence. Part of the first sub-connecting plate 41 is located in the slide groove 101 and contacts the auxiliary body 23, part of the first sub-connecting plate 41 is located in the second notch 104, and part of the first sub-connecting plate 41 is located in the first notch 103 and contacts the fixing claw 30. Among them, the first sub-connecting plate 41 contacts the outer side of the auxiliary body 23 and the fixing claw 30. The second sub-connecting plate 42 is located on the side close to the reverse side of the base 10. The third sub-connecting plate 43 is located on the inner side close to the base 10, and is used to electrically connect the circuit board 130. It should be noted that the way the third sub-connecting plate 43 is electrically connected to the circuit board 130 is the same as the way the first sub-connecting plate 43a is electrically connected to the circuit board 130 shown in the first embodiment above, and will not be repeated here.

[0318] In this embodiment, one end of the memory wire 50 is fixed to the fixed claw 30, and the other end is fixed to the movable claw 21. Specifically, the processor 140 can power the fixed claw 30 and the auxiliary body 23 through the circuit board 130 and the connecting plate 40. At this time, since the separator 20 is made of conductive material, the movable claw 21 is powered, the memory wire 50 is powered, the memory wire 50 shrinks due to the increase in temperature, and the length of the memory wire 50 is shortened, driving the separator 20 to rotate counterclockwise relative to the base 10. At this time, the reset member 11 will be elastically deformed and elongated under the drive of the separator 20.

[0319] The processor 140 can cut off the power to the fixed claw 30 and the auxiliary body 23 through the circuit board 130 and the connecting plate 40. At this time, the movable claw 21 is cut off, and the memory wire 50 is cut off, that is, there is no current on the memory wire 50, and the memory wire 50 will not shrink due to the increase in temperature. At this time, the memory wire 50 can be stretched and deformed under the action of external force and its length is extended.

[0320] Exemplarily, the separator 20 can rotate in a clockwise direction relative to the base 10 under the action of an external force, and the separator 20 will generate a pulling force on the memory wire 50, so that the memory wire 50 is stretched and deformed and its length is extended. In this embodiment, the reset member 11 in the stretched state will return to its original shape and its length will be shortened, and the reset member 11 will drive the separator 20 to rotate in a clockwise direction, so that the memory wire 50 is stretched and deformed and its length is extended under the drive of the separator 20.

[0321] Next, taking the original length of the reset member 11 as l0, the current carried by the memory metal wire 50 as I, and the length of the memory metal wire 50 as L2 as an example, the switch assembly 160 in different states is described.

[0322] Please also read Figure 7 and Figure 8 When the separator 20 is located at the first position, the memory metal wire 50 is in a power-off state, the length of the memory metal wire 50 is L5, and the length of the reset element 11 is l0. Wherein, L5>L2.

[0323] Processor 140 (eg Figure 6 As shown in the figure, the movable claw 21 and the fixed claw 30 can be powered through the circuit board 130 and the connecting plate 40, so that the memory wire 50 carries a current of magnitude I. The memory wire 50 is heated and shortened under the action of the current, thereby driving the partition 20 to rotate counterclockwise relative to the base 10 in the slide groove 101. At this time, the reset member 11 is elastically deformed and elongated under the drive of the partition 20.

[0324] When the length of the memory wire 50 is shortened to L2, the partition 20 is exactly located at the second position, and the length of the reset member 11 is l3. Wherein, l3>l0. At this time, the switch assembly 160 is in the open state, the second connecting portion 201 of the partition 20 and the first connecting portion 102 of the base 10 are enclosed to form a connecting hole 161, the sound outlet hole 1102 is connected to the sound outlet channel 1142, the electric energy sound converter 150 can emit sound through the sound outlet hole 1102 and the receiving hole 1103 at the same time, and the electronic device 100 is in the external speaker mode.

[0325] It is understandable that when the memory metal wire 50 carries a current of magnitude I, the second connecting portion 201 of the separator 20 and the first connecting portion 102 of the base 10 enclose a connecting hole 161 with the largest volume. In some other embodiments, when the memory metal wire 50 carries a current value slightly less than I, the second connecting portion 201 of the separator 20 and the first connecting portion 102 of the base 10 may enclose a connecting hole 161 with a smaller volume. At this time, the switch assembly 160 is also in the open state, and the electronic device 100 is still in the external speaker mode. Due to the small volume of the connecting hole 161, the external speaker loudness of the electronic device 100 will be relatively reduced.

[0326] When the separator 20 is located at the second position, the memory metal wire 50 carries a current of magnitude I, the length of the memory metal wire 50 is L3, and the length of the reset element 11 is l3.

[0327] The processor 140 can cut off the power to the movable claw 21 and the fixed claw 30 through the circuit board 130 and the connecting plate 40, so that the memory wire 50 does not carry current. The memory wire 50 will not shrink without the action of current. The reset member 11 in the stretched state will return to its original shape and shorten its length, thereby driving the partition 20 to rotate in the clockwise direction (ω direction in the figure) relative to the base 10, and the memory wire 50 will be stretched and deformed by the partition 20 and extend its length.

[0328] When the length of the reset member 11 is shortened to l0, the partition 20 is just located at the first position, and the length of the memory wire 50 is extended to L5. At this time, the switch assembly 160 is in the closed state, the partition 20 blocks the sound outlet channel 1142 and the sound outlet hole 1102, the electric energy sound converter 150 can only emit sound through the receiver hole 1103, and the electronic device 100 is in the handset mode.

[0329] It is understandable that when the memory metal wire 50 carries a current of 0, the separator 20 completely blocks the first connecting portion 102 of the base 10. In some other embodiments, when the memory metal wire 50 carries a current with a current value greater than 0, the separator 20 may not completely block the first connecting portion 102 of the base 10. At this time, the second connecting portion 201 of the separator 20 and the first connecting portion 102 of the base 10 can be enclosed to form a smaller connecting hole 161. At this time, the electric energy sound converter 150 can also emit sound through the sound outlet 1103, which can not only avoid a large amount of leakage of the electronic device 100, but also increase the loudness of the earpiece of the electronic device 100.

[0330] In the electronic device 100 shown in the present embodiment, the memory metal wire 50 is used to control the rotation of the partition 20 relative to the base 10 to realize the connectivity between the sound channel 1142 and the sound hole 1102. When the sound hole 1102 is not in use, the sound hole 1102 can be closed to prevent external dust and other impurities from entering the front sound cavity 1501 through the sound hole 1102 and affecting the sound quality, thereby improving the dustproof effect of the electronic device 100 and ensuring the sealing of the electronic device 100.

[0331] In addition, the processor 140 is used to adjust the current carried by the memory metal wire 50 to adjust the rotation angle of the partition 20 relative to the base 10 in the slide groove 101, which can not only achieve active adjustment of the earpiece loudness and leakage volume of the electronic device 100, but also achieve adjustment of the external speaker loudness of the electronic device 100.

[0333] In this embodiment, the driving mechanism 160a includes a base 10, a fixed claw 30, a connecting plate 40 and a memory wire 50.

[0335] The switch assembly 160 shown in the embodiment of the present application is different from the switch assembly 160 shown in the first embodiment described above in that the slide groove 101 of the base 10 also penetrates the outer side surface of the base 10. In addition, the base 10 is also provided with a mounting hole 108. The opening of the mounting hole 108 is located on the groove side wall of the slide groove 101.

That is, the groove side wall of the slide groove 101 is partially recessed to form the mounting hole 108. There are two mounting holes 108, and the two mounting holes 108 are arranged at intervals along the X-axis direction. Among them, the two mounting holes 108 are respectively a first mounting hole 108a and a second mounting hole 108b.

[0336] Please also read Fig. 27 , Fig. 27 yes Fig.25 The schematic diagram of the assembly structure of the base 10 and the reset member 11 in the switch assembly 160 is shown.

[0337] In addition, the driving mechanism 160a further includes a reset member 11. There are two reset members 11, both of which are mounted on the base 10 and arranged at intervals along the X-axis direction. Specifically, the two reset members 11 are respectively mounted on the two mounting holes 108. The two reset members 11 are respectively mounted on the hole walls of the two mounting holes 108, and part of the reset members 11 is exposed relative to the groove side wall of the slide groove 101.

[0338] In this embodiment, the two reset members 11 are respectively a first reset member 11a and a second reset member 11b, and the first reset member 11a is located on the side of the second reset member 11b facing the positive direction of the X-axis.

One end of the second reset member 11b is fixedly connected to the hole wall of the second mounting hole 108, and the other end is exposed relative to the groove side wall of the slide groove 101.

[0339] See also Fig.25 , the separator 20 is installed in the slide slot 101 and can move in the slide slot 101 along the Y-axis direction. Exemplarily, the first position is located on the side of the second position facing the negative direction of the Y-axis. The direction from the first position to the second position is along the positive direction of the Y-axis. The direction from the second position to the first position is along the negative direction of the Y-axis.

[0340] In addition, the separator 20 is fixedly connected to the two reset members 11, so as to move along the Y-axis direction under the drive of the two reset members 11. Specifically, the main body 22 of the separator 20 is fixedly connected to the two reset members 11. Among them, one end of the main body 22 close to the first movable claw 21a is fixedly connected to the first reset member 11a, and one end of the main body 22 close to the second movable claw 21b is fixedly connected to the second reset member 11b.

[0341] In this embodiment, both reset members 11 are compression springs, and the elastic force directions of both reset members 11 are in the Y-axis direction. At this time, both reset members 11 are connected between the base 10 and the partition 20, and can limit the partition 20 in the Y-axis direction, limit the moving distance of the partition 20 relative to the base 10 along the Y-axis direction, ensure the connection stability between the partition 20 and the base 10, improve the connection stability between the partition 20 and the driving mechanism 160a, and ensure the overall structural stability of the switch assembly 160. In some other embodiments, the reset member 11 can also be an elastic glue or other elastic member.

[0342] It should be noted that, in some other embodiments, the number of the reset members 11 may be one, three or more than four, and each reset member 11 is connected between the base 10 and the partition 20. In this case, the number of the mounting holes 108 of the base 10 is equal to or greater than the number of the reset members 11, and the partition 20 can also move relative to the base 10 along the negative direction of the Z axis under the drive of the reset members 11.

[0343] When the partition 20 is in the first position, the switch assembly 160 is in a closed state, the partition 20 blocks the opening of the sound hole 1102 toward the mounting groove 1101 to block the sound hole 1102 and the sound channel 1142, and the first reset member 11a and the second reset member 11b are both in a free state.

[0344] When the partition 20 is located at the second position, the switch assembly 20 is in an open state, the sound outlet hole 1102 is connected to the sound outlet channel 1142, and the first restoring member 11a and the second restoring member 11b are both in a compressed state.

[0345] In addition, the driving mechanism 160a also includes a base 70, which is fixed to a side of the base 10 close to the inner side, that is, the base 70 and the fixed claw 30 are fixed to the same side of the base 10. In the present embodiment, there are two bases 70, and the two bases 70 are arranged at intervals along the X-axis direction. Exemplarily, the two bases 70 are respectively a first base 70a and a second base 70b, and the first base 70a is located on the side of the second base 70b facing the positive direction of the X-axis. The first fixed claw 30a is installed on the surface of the first base 70a facing the base 10, and the second fixed claw 30b is fixed on the surface of the second base 70a facing the base 10. Among them, the first base 70a and the base 10 are arranged at intervals along the Y-axis direction, and the second base 70a and the base 10 are arranged at intervals along the Y-axis direction.

[0346] In some other embodiments, the driving mechanism 160a may also not include the base 70. In this case, the first fixing claw 30a and the second fixing claw 30b may be fixed to the side wall of the sliding groove 101.

[0347] The two connecting plates 40 are both mounted on the base 10 and arranged at intervals along the X-axis direction. The first sub-connecting plate 41a of the first connecting plate 40a contacts the inner side of the first movable claw 21a, and the third sub-connecting plate 43a contacts the outer side of the first fixed claw 30a. The first sub-connecting plate 41a of the second connecting plate 40b contacts the inner side of the second movable claw 21b, and the third sub-connecting plate 43b contacts the outer side of the second fixed claw 30a.

[0348] In this embodiment, both connecting plates 40 are flexible circuit boards. The first connecting plate 40a is fixedly connected to the first movable claw 21a, and the second connecting plate 40a is fixedly connected to the second movable claw 21b. At this time, the first connecting plate 40a and the second connecting plate 40a can follow the separator 20 to move relative to the base 10. In some other embodiments, both connecting plates 40 can be rigid circuit boards. The first connecting plate 40a can be connected to the first movable claw 21a through a first connecting line (not shown), and the second connecting plate 40b can be connected to the second movable claw 21b through a second connecting line (not shown). At this time, the first connecting line and the second connecting line can follow the separator 20 to move relative to the base 10.

[0349] The two memory wires 50 are respectively a first memory wire 50a and a second memory wire 50b. One end of the first memory wire 50a is fixed to the first fixed claw 30a, and the other end is fixed to the second movable claw 21b. One end of the second memory wire 50b is fixed to the second fixed claw 30b, and the other end is fixed to the first movable claw 21a.

[0350] Processor 140 (eg Figure 2As shown in FIG. 1 , the first fixed claw 30a and the second movable claw 21b can be powered on through the circuit board 130 and the first connecting plate 40a, and the second fixed claw 30b and the first movable claw 21a can be powered on through the circuit board 130 and the second connecting plate 40b. At this time, the first memory wire 50a and the second memory wire 50b are both powered on, and the first memory wire 50a and the second memory wire 50b shrink due to the increase in temperature. The length of the first memory wire 50a and the second memory wire 50b is shortened, which will generate a pulling force along the positive direction of the Y axis on the separator 20, driving the separator 20 to move in the positive direction of the Y axis relative to the base 10 in the slide groove 101. At this time, the first reset member 11a and the second reset member 11b will be elastically deformed and shortened in length under the drive of the separator 20.

[0351] The processor 140 cuts off the power to the first fixed claw 30a and the second movable claw 21b via the circuit board 130 and the first connecting plate 40a, and cuts off the power to the second fixed claw 30b and the first movable claw 21a via the circuit board 130 and the second connecting plate 40b. At this time, the first memory wire 50a and the second memory wire 50b are both cut off, that is, there is no current on the first memory wire 50a and the second memory wire 50b, and the first memory wire 50a and the second memory wire 50b will not shrink due to the increase in temperature.

[0352] At this time, the first memory metal wire 50a and the second memory metal wire 50b can be stretched and deformed under the action of external force and their lengths can be extended. Exemplarily, the separator 20 can move along the negative direction of the Y axis under the action of external force, and the separator 20 can generate a pulling force along the negative direction of the Y axis on the first memory metal wire 50a and the second memory metal wire 50b, so that the first memory metal wire 50a and the second memory metal wire 50b are stretched and deformed and their lengths can be extended.

[0353] In this embodiment, the first restoring member 11a and the second restoring member 11b in the compressed state will return to their original shape and extend in length. The first restoring member 11a and the second restoring member 11b will apply a pulling force along the negative direction of the Y-axis to the separator 20, that is, the first restoring member 11a and the second restoring member 11b will drive the separator 20 to move along the negative direction of the Y-axis, so that the first memory metal wire 50a and the second memory metal wire 50b are stretched and deformed and extend in length under the drive of the separator 20.

[0354] Next, taking the original length of the reset member 11 as l0, the current carried by the memory metal wire 50 as I, and the length of the memory metal wire 50 as L2 as an example, the switch assembly 160 in different states is described.

[0355] See also Figure 7 and Fig.28 , Fig.28It is a schematic structural diagram of the assembly structure of the middle frame 111, the circuit board 130, the electric energy sound converter 150 and the switch assembly 160 in the fourth electronic device 100 provided in the embodiment of the present application after being cut apart along II-II. Among them, the switch assembly 160 is in an open state.

[0356] When the separator 20 is located at the first position, the two memory metal wires 50 are both in a power-off state, the lengths of the two memory metal wires 50 are both L6, and the lengths of the two reset members 11 are both l0. Wherein, L6>L2.

[0357] Processor 140 (eg Figure 6 (as shown in the figure) the two movable claws 21 and the two fixed claws 30 can be powered through the circuit board 130 and the two connecting plates 40, so that the two memory metal wires 50 are both charged with a current of magnitude I. The two memory metal wires 50 are heated and shortened under the action of the current, thereby driving the partition 20 to move relative to the base 10 in the chute 101 along the positive direction of the Y axis. At this time, the two reset members 11 are elastically deformed and shortened under the drive of the partition 20.

[0358] When the length of the two memory wires 50 is shortened to L2, the partition 20 is exactly in the second position, and the lengths of the two reset members 11 are both l4. Wherein, l4<l0. At this time, the switch assembly 160 is in the open state, the sound outlet channel 1142 is connected to the sound outlet hole 1102, and the sound emitted by the electric energy sound converter 150 can not only be transmitted to the external environment through the sound outlet channel 1142 from the receiving hole 1103, but also can be transmitted to the external environment from the periphery of the base 10 and the partition 20 from the sound outlet hole 1102, and the electronic device 100 is in the external speaker mode.

[0359] When the separator 20 is located at the second position, the two memory metal wires 50 both carry a current of magnitude I, the lengths of the two memory metal wires 50 are both L3, and the lengths of the two reset elements 11 are both l4.

[0360] The processor 140 can stop powering the two connecting plates 40 through the circuit board 130, and then stop powering the two movable claws 21 and the two fixed claws 30, so that the two memory wires 50 are powered off. The two memory wires 50 will not shrink without the action of current. The two reset members 11 in the compressed state will return to their original shape and lengthen, thereby pushing the partition 20 to move relative to the base 10 in the chute 101 along the negative direction of the Y axis, and the two memory wires 50 will be stretched and deformed and lengthened under the drive of the partition 20.

[0361] When the length of the two reset members 11 is restored to l0, the partition 20 is in the first position, and the length of the two memory wires 50 is extended to L6. At this time, the switch assembly 160 is in the closed state, and the partition 20 blocks the opening of the sound outlet 1102 toward the installation groove 1101 to block the sound outlet channel 1142 and the sound outlet 1102. The electric energy sound converter 150 can only emit sound through the receiver hole 1103, and the electronic device 100 is in the handset mode.

[0362] In the electronic device 100 shown in the present embodiment, two memory metal wires 50 are used to control the movement of the partition 20 relative to the base 10 along the Z-axis direction to realize the connectivity between the sound channel 1142 and the sound hole 1102. This not only can close the sound hole 1102 when it is not in use, but also prevent dust and other impurities from entering the front sound cavity 1501 through the sound hole 1102 to affect the sound quality, thereby improving the dustproof effect of the electronic device 100 and ensuring the sealing of the electronic device 100. It can also realize the switching of the electronic device 100 between the external speaker mode and the earpiece mode.

[0363] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application; in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
