Description

Technical Field

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

[0002] Currently, the headphone products on the market are mainly divided into in-ear and non-in-ear headphones. In-ear headphones go deep into the ear canal, have good physical sealing, and excellent sound quality, but the pain point of in-ear headphones is that users feel different degrees of pain after wearing them, especially long-term wearing will aggravate the discomfort of ear canal squeezing. Non-in-ear headphones have a non-sense and painless wearing experience, which solves the above pain points of in-ear headphones, but non-in-ear headphones have poor sealing and poor audio performance in noisy environments such as subways and buses.

[0003] Therefore, how to provide a headset with switchable usage forms is a technical problem that those skilled in the art currently need to solve. Summary of the invention

[0004] The purpose of the embodiment of the present application is to provide a headset that can be switched between in-ear and non-in-ear to enhance the user experience. The specific technical solution is as follows:

[0005] An embodiment of the first aspect of the present application provides an earphone, comprising a shell, wherein a accommodating cavity and a sound outlet channel connected to the accommodating cavity are arranged inside, and an annular receiving groove is arranged around the outer peripheral side of the sound outlet channel, and the receiving groove opens toward the sound outlet direction; a sound-emitting device is located in the accommodating cavity; an earplug assembly comprises an earplug body, the earplug body is provided with a sound outlet hole, and the sound outlet hole is connected to the sound outlet channel; a first elastic member is sleeved on the outside of the sound outlet channel, and its two ends are respectively connected to the earplug body and the bottom of the receiving groove; a locking assembly is connected to the shell, and the locking assembly cooperates with the shell to keep the first elastic member and the earplug body accommodated in the receiving groove in a locked state to form a non-in-ear earphone, and to make the first elastic member drive the earplug body to pop out to the outside of the shell in an unlocked state to form an in-ear earphone.

[0006] In an embodiment of the present application, the earplug assembly includes an earplug body, a housing is provided with a storage slot, and the earphone further includes a locking assembly, which cooperates with the housing to keep the earplug body stored in the storage slot in a locked state, so that when in use, the entire earphone is located outside the human ear canal and does not enter the human ear canal, constituting a non-in-ear earphone. After unlocking, the earplug body can be ejected to the outside of the housing, so that when in use, the earplug body can be inserted into the human ear canal, realizing the switching of the earphone from a non-in-ear form to an in-ear form. In actual applications, users can choose the earphone to be in a non-in-ear form or an in-ear form according to the usage scenario, which is conducive to improving the user experience.

[0007] In some embodiments of the present application, the locking assembly includes a button body and a baffle rod fixedly connected to the button body, the button body is arranged on the shell, and the button body puts the locking assembly in an unlocked state when being pressed, and puts the locking assembly in a locked state when being not pressed; the baffle rod extends deep into the shell, and is used to engage with the earplug assembly in the locked state, and to release the engagement with the earplug assembly in the unlocked state.

[0008] In the embodiment of the present application, a button body is provided to facilitate unlocking. By providing a stopper, the stopper can be engaged with the earplug assembly in a locked state, so that in the locked state, the earplug body can be kept stored in the storage slot, so that the earphone automatically maintains a non-in-ear state. By pressing the button body, the stopper can be driven to move, the stopper and the earplug assembly are released, the earplug assembly is unlocked, and the earplug body is ejected, so that the earphone is switched from a non-in-ear state to an in-ear state.

[0009] In some embodiments of the present application, the earplug assembly also includes a sleeve; the first end of the sleeve is connected to the sound outlet hole of the earplug body, the second end of the sleeve is inserted into the sound outlet channel, and is slidably connected to the inner wall of the sound outlet channel; under the elastic force of the first elastic member, the sleeve slides away from the sound-emitting device and extends out of the sound outlet channel, and drives the earplug body to move to the outside of the shell; the sleeve also slides and shrinks into the sound outlet channel in the direction close to the sound-emitting device under the action of external force, and drives the earplug body to be stored in the storage groove of the shell.

[0010] In the embodiment of the present application, by providing a sleeve, the sound outlet channel and the sound outlet hole of the earplug body can be connected, and the earplug assembly can be slidably connected to the sound outlet channel. As the sleeve slides in the sound outlet channel, the earplug body can be stored in the storage groove or the earplug body can be popped out to the outside of the shell, thereby realizing the switching of the in-ear form and non-in-ear form of the earphone.

[0011] In some embodiments of the present application, a key groove is provided on the surface of the shell, and the key body is accommodated in the key groove when pressed; the stop rod of the locking assembly is connected to the bottom of the key body and extends into the interior of the shell through the key groove, and the stop rod is provided with a first stop portion; the second end of the sleeve is provided with a second stop portion, and the first stop portion and the second stop portion cooperate to limit the sleeve in the axial direction of the sound output channel, so that the sleeve and the earplug body automatically maintain a retracted state; the first stop portion also moves after the button body is pressed to release the stopping cooperation with the second stop portion.

[0012] Thus, the locking assembly can be used to keep the first elastic member and the earplug body stored in the storage groove in the locked state to form a non-in-ear earphone, and in the unlocked state, the first elastic member drives the earplug body to pop out of the shell to form an in-ear earphone.

[0013] In some embodiments of the present application, the inner wall of the sound outlet channel is provided with a first limiting structure, and during the extension of the sleeve, the first limiting structure limits the sliding stroke of the sleeve in the direction away from the sound-generating device, thereby preventing the sleeve from being separated from the sound outlet channel during the sliding process.

[0014] In some embodiments of the present application, the first stopper is a first protrusion disposed on the stopper rod, and the second stopper is a second protrusion disposed on the outer wall surface of the second end of the sleeve; the sound outlet channel is provided with a through hole, and when the sleeve is in a retracted state, the first protrusion passes through the through hole and blocks the side of the second protrusion away from the sound-generating device; during the extension of the sleeve, the second protrusion also cooperates with the first limiting structure to limit the sliding stroke of the sleeve in the direction away from the sound-generating device.

[0016] In some embodiments of the present application, the locking assembly further includes a second elastic member, one end of the second elastic member is connected to the bottom of the key body, and the other end of the second elastic member is connected to the housing, and the key body is automatically reset from the pressed state under the elastic force of the second elastic member. Thus, the key body can be automatically reset.

[0017] In some embodiments of the present application, the housing is further provided with a second limiting structure, and the second limiting structure is used to limit the movement stroke of the key body, thereby preventing the key body from being separated from the housing during the resetting process.

[0018] In some embodiments of the present application, the sleeve and the earplug body are integrally formed, or the sleeve and the earplug body are separate structures, and the sleeve and the earplug body are snap-fitted and connected. Thus, the connection between the sleeve and the earplug body is simple.

[0019] In some embodiments of the present application, the earplug body includes a connecting portion, a bending portion, and an ear cap portion, wherein the connecting portion is connected to the first end of the sleeve, the bending portion is connected to the connecting portion and the ear cap portion respectively, and the bending portion can be bent and deformed to be accommodated inside the sleeve, or the bending portion extends to the outside of the sleeve so that the ear cap portion moves axially relative to the sleeve. Thus, by pulling the ear cap portion of the earplug body, the bending portion can be stretched and deformed, so that the ear cap portion moves relative to the sleeve in a direction away from the sound-emitting device, so that the length of the earplug body extending out of the shell can be increased, so that it is suitable for different users to wear.

[0020] In some embodiments of the present application, the sleeve includes a first sub-sleeve and a second sub-sleeve nested inside the first sub-sleeve, the first end of the first sub-sleeve is connected to the first elastic member, the second end of the first sub-sleeve is inserted into the sound outlet channel and slidably connected to the sound outlet channel, and the first sub-sleeve slides in a direction away from the sound-emitting device and extends out of the sound outlet channel under the elastic force of the first elastic member; the second sub-sleeve is slidably connected to the inner wall of the first sub-sleeve; the first end of the second sub-sleeve is connected to the sound outlet hole of the earplug body, and the second end of the second sub-sleeve is connected to the second end of the first sub-sleeve through a third elastic member, and the second sub-sleeve slides in a direction away from the sound-emitting device and extends out of the first sub-sleeve under the elastic force of the third elastic member; the second sub-sleeve also slides and shrinks into the first sub-sleeve in a direction close to the sound-emitting device under the action of an external force, and the first sub-sleeve also slides and shrinks into the sound outlet channel in a direction close to the sound-emitting device under the action of an external force.

[0021] In the embodiment of the present application, by controlling the extension and retraction of the first sub-sleeve and the second sub-sleeve, the earphone can be placed in a non-in-ear form, a semi-in-ear form or an in-ear form, thereby making the earphone suitable for different situations or different groups of people and expanding the scope of use of the earphone.

[0022] In some embodiments of the present application, a third limiting structure is provided on the inner wall of the first sub-sleeve, and the third limiting structure cooperates with the second sub-sleeve in a retracted state of the second sub-sleeve and / or in an extended state of the second sub-sleeve to axially limit the second sub-sleeve.

[0023] In the embodiment of the present application, the second sub-sleeve can be axially limited by the third limiting structure and the second sub-sleeve limiting position when the second sub-sleeve is in a retracted state. Thus, the second sub-sleeve can be automatically retracted. The second sub-sleeve can be axially limited by the third limiting structure and the second sub-sleeve limiting position when the second sub-sleeve is in an extended state. Thus, after the second sub-sleeve is extended, it can be prevented from retracting after being accidentally touched, so that it can remain in an extended state.

After the second sub-sleeve is rotated, the third protrusion enters the limiting release groove from the first limiting groove or the second limiting groove to release the axial limitation of the second sub-sleeve.

[0025] In the embodiment of the present application, by providing the first limiting groove, the second sub-sleeve can be limited after it is contracted, so that the second sub-sleeve can remain automatically contracted. By providing the second limiting groove, the second sub-sleeve can be limited during the extension process of the second sub-sleeve to prevent the second sub-sleeve from contracting after an accidental touch, so that it remains in the extended state. By providing the limiting release groove, the axial limit of the second sub-sleeve can be contacted.

[0027] In the embodiment of the present application, by configuring the sleeve to include a plurality of nested multi-stage sub-sleeves, after the sleeve is extended, its extended length is equal to the sum of the sliding distances of the plurality of sub-sleeves, and the extended length is longer. At the same time, after the sleeve is retracted, the plurality of sub-sleeves are nested together, so that the overall length of the sleeve is shorter, so that it can be accommodated in the sound outlet channel. Thus, the sleeve can have a larger extended length while meeting the miniaturization design of the earphone.

[0028] In some embodiments of the present application, the sound outlet channel is provided with a fourth limiting structure, and the fourth limiting structure limits the sliding stroke of the first-stage sub-sleeve in the direction away from the sound-generating device; each sub-sleeve except the last-stage sub-sleeve is also provided with a fifth limiting structure, and the fifth limiting structure is used to limit the sliding stroke of the next-stage sub-sleeve in the direction away from the sound-generating device. By providing the fourth limiting structure and the fifth limiting structure, the sub-sleeves of each stage can be prevented from being disengaged during the sliding process.

[0029] In some embodiments of the present application, the earplug assembly further includes a pleated sleeve, a first end of the pleated sleeve being connected to the sound outlet hole of the earplug body, a second end of the pleated sleeve being fixed in the sound outlet channel, and the pleated sleeve further including a pleated portion, which can be extended and deformed along the sound outlet direction; the first end of the pleated sleeve is connected to the first elastic member, the pleated portion of the pleated sleeve is stretched and deformed under the elastic force of the first elastic member so as to extend out of the sound outlet channel, and the pleated portion of the pleated sleeve is pleated and deformed under the action of an external force so as to shrink into the sound outlet channel.

[0030] In the embodiment of the present application, the pleated portion can be stretched and deformed so that the pleated sleeve extends out of the sound outlet channel, thereby realizing the in-ear form of the earphone. The pleated portion can be deformed by an external force such as pressing the earplug body and contracted into the sound outlet channel, thereby realizing the non-in-ear form of the earphone.

[0032] In the embodiment of the present application, the earplug assembly can be locked or unlocked through the cooperation of the sixth limiting structure and the locking assembly, so as to facilitate the control of the usage mode of the earphone.

[0033] In some embodiments of the present application, the sixth limiting structure is a cantilever beam arranged in the receiving groove; the cantilever beam includes a vertical portion and a horizontal portion, one end of the vertical portion is fixed to the bottom wall of the receiving groove, the other end of the vertical portion extends in a direction away from the sound-emitting device and is connected to one end of the horizontal portion, and the other end of the horizontal portion extends in an axial direction close to the sound output channel, so as to block the side of the first end of the pleated sleeve away from the sound-emitting device when the pleated sleeve is in a contracted state; the end of the sliding rod away from the key body extends into the receiving groove and is located on a side of the vertical portion of the cantilever beam close to the sound output channel; the sliding rod includes a flange portion, which protrudes in a direction away from the sound output channel, and the flange portion contacts the vertical portion of the cantilever beam after the key body is pressed, and pushes the end of the vertical portion connected to the horizontal portion to move in a direction away from the sound output channel, so as to separate the horizontal portion from the first end of the pleated sleeve.

[0034] In the embodiment of the present application, by providing a cantilever beam, the horizontal portion of the cantilever beam can be blocked at the side of the first end of the pleated sleeve away from the sound-generating device in the locked state, so that the pleated sleeve can maintain the pleated contracted state. By pressing the button body, the slide bar can be driven to move, so that the flange portion of the slide bar moves and contacts the vertical portion of the cantilever beam, and pushes the end of the vertical portion connected to the horizontal portion to move away from the sound outlet channel, thereby separating the horizontal portion from the first end of the pleated sleeve and releasing the position-limiting clamping of the pleated sleeve.

Thus, the key body can be automatically reset.

[0036] In some embodiments of the present application, the earphone further comprises an ear hook connected to the housing and hung on a human ear when in use, so that the housing fits against the outer auricle of the human body. Thus, the earphone can be used more conveniently.

[0037] In some embodiments of the present application, the first elastic member is a cylindrical helical spring or a conical helical spring or a spring sheet, so that the spring and spring sheet can be selected from a wide variety of options and are easy to purchase.

[0038] An embodiment of the second aspect of the present application provides an earphone, comprising a shell, which is provided with a accommodating cavity and a sound outlet channel connected to the accommodating cavity; a sound-emitting device is located in the accommodating cavity; an earplug accessory is detachably connected to the shell, and the earplug accessory comprises an earplug body, and the earplug body is provided with a sound outlet hole.

[0039] In the embodiment of the present application, by connecting the earplug assembly to the shell, an in-ear earphone can be formed, and the earplug body can enter the human ear canal to achieve in-ear use. By removing the earplug body from the shell, a non-in-ear earphone can be formed, and when in use, it is only necessary to attach the shell to the outer auricle of the human body to achieve non-in-ear use. Therefore, the switching between the in-ear form and the non-in-ear form of the earphone can be achieved by connecting or disassembling the earplug assembly to the shell, which is conducive to users choosing a more suitable earphone form according to the usage scenario and improving the user experience.

[0040] In some embodiments of the present application, the shell is snap-fitted with the earplug body so that the sound outlet hole is connected with the sound outlet channel to form an in-ear earphone. Thus, the connection between the shell and the earplug body is simple.

[0105] As mentioned in the background technology, in-ear headphones go deep into the ear canal, have good physical sealing, and excellent sound quality, but the pain point of in-ear headphones is that users feel pain to varying degrees after wearing them, especially long-term wearing will aggravate the discomfort of ear canal squeezing. Non-in-ear headphones have a non-sense and painless wearing experience, solving the above pain points of in-ear headphones, but non-in-ear headphones have poor sealing and poor audio performance in noisy environments such as subways and buses.

[0106] In view of this, an embodiment of the present application provides an earphone 10 that can be switched between in-ear type and non-in-ear type to enhance the user experience.

[0107] See also Figures 1a to 2c ,in, Figure 1a Schematic diagram 1 of the external appearance of the earphone 10 in the non-in-ear state according to the first embodiment of the first aspect of the present application; Figure 1b for Figure 1a Schematic diagram 2 of the external appearance of the earphone 10 in a non-in-ear configuration at another angle; Figure 1c for Figure 1a The schematic cross-sectional view of the earphone 10 in the XZ plane is shown; Figure 1d for Figure 1a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown; Figure 2a for Figure 1a The external appearance of the earphone 10 shown is a schematic diagram in the in-ear configuration; Figure 2b for Figure 2a The schematic cross-sectional view of the earphone 10 in the XZ plane is shown; Figure 2c for Figure 2a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown.

[0108] like Figure 1a to Figure 1dAs shown, in the first embodiment of the first aspect of the present application, the earphone 10 includes a housing 100, a sound-generating device 200, an earplug assembly 300, a first elastic member 400, and a locking assembly 500. The housing 100 is provided with a receiving cavity 110 and a sound outlet channel 120 connected to the receiving cavity 110, and an annular receiving groove 130 is provided on the outer circumference of the sound outlet channel 120, and the receiving groove 130 opens toward the sound outlet direction Z. The sound-generating device 200 is located in the receiving cavity 110.

[0109] like Figure 1a As shown, the earplug assembly 300 includes an earplug body 310, and the earplug body 310 is provided with a sound outlet hole 311, and the sound outlet hole 311 is connected to the sound outlet channel 120. Figure 1c and Figure 1d As shown, the first elastic member 400 is sleeved on the outside of the sound outlet channel 120 , and two ends thereof are respectively connected to the earplug body 310 and the bottom of the storage groove 130 .

[0110] like Figure 1a to Figure 1d As shown, the locking assembly 500 is connected to the housing 100, and the locking assembly 500 cooperates with the housing 100 to keep the first elastic member 400 and the earplug body 310 stored in the storage groove 130 in the locked state, forming a non-in-ear earphone, and as shown Figure 2a to Figure 2c As shown, in the unlocked state, the first elastic member 400 drives the earplug body 310 to pop out to the outside of the housing 100 to form an in-ear earphone.

[0111] In the embodiment of the present application, the earplug assembly 300 includes an earplug body 310, a housing 100 is provided with a storage slot 130, and the earphone 10 further includes a locking assembly 500, and the locking assembly 500 cooperates with the housing 100 to keep the earplug body 310 stored in the storage slot 130 in a locked state, so that when in use, the entire earphone 10 is located outside the human ear canal and does not enter the human ear canal, forming a non-in-ear earphone. After unlocking, the earplug body 310 can be ejected to the outside of the housing 100, so that when in use, the earplug body 310 can be inserted into the human ear canal, so that the earphone 10 can be switched from a non-in-ear form to an in-ear form. In actual applications, users can choose the earphone 10 to be a non-in-ear form or an in-ear form according to the usage scenario, which is conducive to improving the user experience.

[0112] In a specific embodiment, in the in-ear configuration, the earplug body 310 protrudes from the housing 100, and the step difference between the earplug body 310 and the housing 100 is greater than 4 mm. In the non-in-ear configuration, the earplug body 310 is received in the receiving groove 130, and the step difference between the side surface of the earplug body 310 away from the sound-generating device 200 and the housing 100 is less than 3 mm.

[0113] like Figure 1c , Figure 1d , Figure 2b and Figure 2c As shown, in the first embodiment, the earplug assembly 300 may include a sleeve 320, a first end of which is connected to the sound outlet hole 311 of the earplug body 310. A second end of the sleeve 320 is inserted into the sound outlet channel 120 and slidably connected to the inner wall of the sound outlet channel 120.

[0114] Optionally, the sleeve 320 is integrally formed with the earplug body 310. Figure 3 , Figure 3 for Figure 1c The earplug body 310 is shown as a schematic diagram of the buckle connection between the sleeve 320. Figure 3 As shown, the sleeve 320 and the earplug body 310 are split structures, a first end of the sleeve 320 is provided with a slot 321, and the earplug body 310 is provided with a buckle 312. By snapping the buckle 312 into the slot 321, the sleeve 320 and the earplug body 310 are snap-connected.

[0115] like Figure 1c and Figure 1d As shown, the first end of the sleeve 320 is connected to one end of the first elastic member 400 through the earplug body 310. The first elastic member 400 can be a cylindrical coil spring. The first elastic member 400 is located in the storage groove 130 and surrounds the outside of the sound outlet channel 120. The other end of the first elastic member 400 is connected to the bottom wall of the storage groove 130.

[0116] like Figure 2b and Figure 2c As shown, the sleeve 320 slides out of the sound outlet channel 120 in a direction away from the sound-generating device 200 under the elastic force of the first elastic member 400, and drives the earplug body 310 to move to the outside of the housing 100; at this time, the locking assembly 500 is in an unlocked state. Figure 1c and Figure 1d As shown, the sleeve 320 also slides and retracts into the sound outlet channel 120 in the direction close to the sound device 200 under the action of an external force, such as pressing the earplug body 310, and drives the earplug body 310 to be stored in the storage groove 130 of the housing 100; at this time, the locking assembly 500 is in a locked state. During the sliding and retracting process of the sleeve 320, the sleeve 320 continuously moves in the direction close to the sound device 200 until it abuts against the end of the sound outlet channel 120 that is away from the sound device 200.

[0117] By setting the sleeve 320, the sound outlet channel 120 and the sound outlet hole 311 of the earplug body 310 can be connected, and the earplug assembly 300 can be slidably connected to the sound outlet channel 120. As the sleeve 320 slides in the sound outlet channel 120, the earplug body 310 can be stored in the storage groove 130 or the earplug body 310 can be popped out to the outside of the shell 100, thereby realizing the switching of the in-ear form and the non-in-ear form of the earphone 10.

[0118] In other embodiments of the present application, the first elastic member 400 may also be a spring sheet, which may include two connected spring sheet parts, the two spring sheet parts have a certain angle, and the two spring sheet parts are respectively connected to the bottom wall of the receiving groove 130 and the first end of the sleeve 320. In the locked state, the angle between the two spring sheet parts is compressed and becomes smaller. After unlocking, the angle between the two spring sheet parts is reset and becomes larger, thereby driving the sleeve 320 to slide in a direction away from the sound-generating device 200. The present application does not limit this.

[0119] See also Figures 4a to 4c , Figure 4a for Figure 1a The schematic cross-sectional view of the earphone 10 in the locked state in the XY plane is shown; Figure 4b for Figure 1a The schematic cross-sectional view of the earphone 10 in the unlocked state in the XY plane is shown; Figure 4c for Figure 4a A schematic structural diagram of the locking assembly 500 is shown.

[0120] like Figures 4a to 4c As shown, in the first embodiment, the locking assembly 500 may include a button body 510 and a stopper 520 fixedly connected to the button body 510. The button body 510 is disposed on the housing 100. When the button body 510 is pressed, the locking assembly 500 is in an unlocked state, and when it is not pressed, the locking assembly 500 is in a locked state. The stopper 520 extends deep into the housing 100. The stopper 520 is engaged with the earplug assembly 300 in the locked state, and is released from the engagement with the earplug assembly 300 in the unlocked state.

[0121] By providing the blocking rod 520, the blocking rod 520 can be engaged with the earplug assembly 300 in the locked state, so that in the locked state, the earplug body 310 can remain stored in the storage groove 130, so that the earphone 10 automatically maintains the non-in-ear state. By pressing the button body 510, the blocking rod 520 can be driven to move, the blocking rod 520 and the earplug assembly 300 are released, the earplug assembly 300 is unlocked, and the earplug body 310 is ejected, so that the earphone 10 is switched from the non-in-ear state to the in-ear state.

[0122] It is understood that the locked state means that the earplug assembly 300 is limited in the sound output direction Z so that the earplug body 310 remains retracted in the storage cavity. The unlocked state means that the limiting effect on the earplug assembly 300 is released so that the earplug body 310 can pop out of the housing 100.

[0123] Specifically, Figure 1d As shown, in the first embodiment, a key slot 140 is provided on the surface of the housing 100. In the sound output direction Z, the key slot 140 is provided in the portion of the housing 100 between the receiving slot 130 and the accommodating cavity 110. Figure 4a and Figure 4b As shown, the key body 510 is accommodated in the key slot 140 in the pressed state. The stopper 520 of the locking assembly 500 is connected to the bottom of the key body 510 and extends into the interior of the housing 100 through the key slot 140. The stopper 520 is provided with a first stopper 521, which can be a first protrusion 5211 formed by a part of the stopper 520 protruding toward the direction close to the sound outlet channel 120.

[0124] See also Figure 1c , Figure 5 and Figure 6 , Figure 5 for Figure 1c A schematic diagram of the structure of the sleeve shown; Figure 6 for Figure 1c The second end of the sleeve 320 is provided with a second stopper 322, and the second stopper 322 may be a second protrusion 3221 provided on the outer wall of the second end of the sleeve 320. The inner wall of the sound outlet channel 120 may be provided with a first sliding groove 122, and the first sliding groove 122 extends along the axial direction of the sound outlet channel 120. The second protrusion 3221 is inserted into the first sliding groove 122 and slidably cooperates with the first sliding groove 122, thereby realizing the sliding connection between the sleeve 320 and the sound outlet channel 120.

[0125] The inner wall of the sound outlet channel 120 may also be provided with a through hole 123, and the through hole 123 may be located on a side of the first sliding groove 122 close to the sound generating device 200. Figure 1c As shown, the first protrusion 5211 can pass through the through hole 123 into the sound outlet channel 120 and block the side of the second protrusion 3221 away from the sound-emitting device 200, thereby preventing the second protrusion 3221 from sliding along the sound outlet direction Z, so that the sleeve 320 remains retracted in the sound outlet channel 120, and the earplug assembly 300 is locked after it is retracted, so that the earphone 10 automatically maintains a non-in-ear shape.

[0126] like Figure 4bAs shown, when the button body 510 is pressed, the blocking rod 520 moves with the button body 510, so that the first protrusion 5211 moves, and then staggers with the second protrusion 3221 in the axial direction of the sound outlet channel 120, and the blocking of the second protrusion 3221 is released to achieve unlocking. After unlocking, under the elastic force of the first elastic member 400, the second protrusion 3221 slides in the first sliding groove 122 in a direction away from the sound-emitting device 200, so that the sleeve 320 extends to the outside of the sound outlet channel 120, and drives the earphone 10 to move to the outside of the housing 100, so that the earphone 10 switches to the in-ear state.

[0127] Preferably, if Figures 4a to 4c As shown, in embodiment one, two baffle rods 520 are provided, and the two baffle rods 520 are symmetrically arranged about the axis of the sound outlet channel 120, and two second protrusions 3221 of the sleeve 320 are symmetrically arranged. In the locked state, the first protrusions 5211 of the two baffle rods 520 respectively correspond to the two second protrusions 3221 of the sleeve 320 in a limiting cooperation, thereby ensuring the stability of the limiting cooperation between the baffle rod 520 and the sleeve 320 in the locked state.

[0128] like Figure 6 As shown, the inner wall of the sound outlet channel 120 is provided with a first limiting structure 121, and during the extension of the sleeve 320, the first limiting structure 121 limits the sliding stroke of the sleeve 320 in the direction away from the sound-generating device 200. Thus, the sleeve 320 can be prevented from being separated from the sound outlet channel 120 during the sliding process.

[0129] Specifically, Figure 2b As shown, the groove wall at one end of the first sliding groove 122 away from the sound-generating device 200 constitutes the first limiting structure 121. When the sleeve 320 is extended, the second protrusion 3221 slides in the first sliding groove 122 in a direction away from the sound-generating device 200 to the end of the first sliding groove 122 away from the sound-generating device 200, and is then blocked by the groove wall at the end, thereby preventing the second protrusion 3221 from sliding out of the sound outlet channel 120.

[0130] In other embodiments of the present application, the first stop portion 521 and the second stop portion 322 may be limiting structures such as grooves or snaps, and the present application does not impose any restrictions on this, as long as the first stop portion 521 and the second stop portion 322 can achieve limiting blocking in the locked state and release the limiting blocking in the unlocked state.

[0131] In the first embodiment, Figure 6 As shown, the inner wall of the sound outlet channel 120 is also provided with a positioning slot 124. Figure 5As shown, the outer wall of the sleeve 320 is also provided with a positioning convex strip 323. When installing the sleeve 320, the positioning convex strip 323 of the sleeve 320 can be aligned with the positioning slot 124 of the sound outlet channel 120, and inserted into the sound outlet channel 120 along the positioning slot 124, thereby facilitating the installation and positioning of the sleeve 320.

[0132] like Figures 4a to 4c As shown, the locking assembly 500 also includes a second elastic member 530 and a guide column 560, one end of the guide column 560 is connected to the bottom of the button body 510, and the other end of the guide column 560 extends in a direction close to the sound outlet channel 120. The second elastic member 530 is sleeved on the guide column 560, one end of the second elastic member 530 is connected to the bottom of the button body 510, and the other end of the second elastic member 530 extends into the button groove 140 and is connected to the housing 100. The button body 510 automatically resets from the pressed state under the elastic force of the second elastic member 530. Therefore, after the button body 510 is pressed, the button body 510 can be automatically reset, which facilitates the operation of the headset 10. Optionally, the second elastic member 530 is a spring.

[0133] The housing 100 is further provided with a second limiting structure 150, which is used to limit the moving stroke of the key body 510. Thus, the reset stroke of the key body 510 can be limited to prevent the key body 510 from being separated.

[0134] Alternatively, if Figure 4a and Figure 4b As shown, the second limiting structure 150 may be a limiting block 151 disposed inside the housing 100, the lower portion of the key body 510 is connected to the limiting frame 540, and the limiting block 151 is inserted into the limiting frame 540 and slidably cooperates with the limiting frame 540. During the reset process of the key body 510, the key body 510 moves upward relative to the limiting block 151 under the elastic force of the second elastic member 530 until the bottom surface of the limiting frame 540 contacts the limiting block 151, and then the key body 510 stops moving and reset is completed.

[0135] See also Figure 7 , Figure 7 for Figure 1c Schematic diagram of the buckle connection between the key body and the key slot shown.

[0136] like Figure 7 As shown, the second limiting structure 150 of the shell 100 can also be a block 152 arranged at the top of the key groove 140, and the outer peripheral surface of the bottom end of the key body 510 is provided with a flange 511. During the resetting process of the key body 510, the key body 510 continuously moves upward under the elastic force of the second elastic member 530 until the flange 511 contacts the block 152, and then the key body 510 stops moving and the resetting is completed.

[0137] The present application does not limit the specific form of the second limiting structure 150 , as long as it can achieve limiting cooperation for the button body 510 when the button body 510 is reset.

[0138] In other embodiments, Figures 1a to 7 The earphone 10 shown can be used as an earphone body in conjunction with accessories such as an ear hook or a neck hook.

[0139] See also Figure 8 and Fig. 9 , Figure 8 for Figure 1a The headphone ear hook usage diagram shown; Fig. 9 for Figure 1a The picture shows the usage of the earphone hanging around the neck.

[0140] like Figure 8 As shown, in the embodiment of the present application, the earphone 10 may further include an ear hook 600, which is connected to the housing 100. When in use, the ear hook 600 may be hung on the human ear so that the housing 100 fits against the outer auricle of the human body. Thus, the earphone 10 may fit against the outer auricle of the human body in a non-in-ear configuration.

[0141] Furthermore, the earphone 10 can be a neck-hanging earphone, and the earphone 10 is also provided with a connecting ring 700, and the connecting ring 700 can be hung on the neck of a human body when in use, thereby making it more convenient to use.

[0142] See also Fig.10a and Fig.10b , Fig.10a It is a schematic cross-sectional view of the earphone 10 in the XZ plane according to the second embodiment of the first aspect of the present application; Fig.10b for Fig.10a The cross-sectional view of the bent portion 314 of the earplug body 310 after being stretched is shown.

[0143] In the second embodiment of the present application, different from the first embodiment, the earplug body 310 includes a connecting portion 313, a bending portion 314 and an ear cap portion 315, wherein the connecting portion 313 is connected to the first end of the sleeve 320, and the bending portion 314 is connected to the connecting portion 313 and the ear cap portion 315 respectively. Fig.10a As shown, the bent portion 314 can be bent and deformed to be accommodated in the interior of the sleeve 320, or, as shown in FIG. Fig.10b As shown, the bent portion 314 extends to the outside of the sleeve 320, so that the ear cap portion 315 moves axially relative to the sleeve 320. Therefore, by pulling the ear cap portion 315 of the earplug body 310, the bent portion 314 can be stretched and deformed, so that the ear cap portion 315 moves relative to the sleeve 320 in a direction away from the sound-generating device 200, so that the length of the earplug body 310 extending out of the housing 100 can be increased, so that it is suitable for different users to wear.

[0144] See also Figures 11a to 13b , Fig.11a It is a schematic cross-sectional view of the earphone 10 in the non-in-ear state in the XZ plane according to the third embodiment of the first aspect of the present application; Fig.11b for Fig.11a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown; Fig.12a for Fig.11a The schematic cross-sectional view of the earphone 10 in the semi-in-ear configuration in the XZ plane is shown; Figure 12b for Fig.12a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown; Fig.13a for Fig.11a The schematic cross-sectional view of the earphone 10 in the in-ear state in the XZ plane is shown; Fig.13b for Fig.13a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown.

[0145] like Figures 11a to 12b As shown, in the third embodiment of the present application, unlike the first embodiment, the sleeve 320 is not a single tubular structure, but includes a first sub-sleeve 330 and a second sub-sleeve 340 nested inside the first sub-sleeve 330, the outer ring 332 of the first end of the first sub-sleeve 330 is connected to the first elastic member 400, the second end of the first sub-sleeve 330 is inserted into the sound outlet channel 120 and is slidably connected to the sound outlet channel 120, and the first sub-sleeve 330 slides in a direction away from the sound-emitting device 200 and extends out of the sound outlet channel 120 under the elastic force of the first elastic member 400.

[0146] like Figures 11a to 13b As shown, the second sub-sleeve 340 is slidably connected to the inner wall of the first sub-sleeve 330; the first end of the second sub-sleeve 340 is connected to the sound outlet hole 311 of the earplug body 310, and the second end of the second sub-sleeve 340 is connected to the second end of the first sub-sleeve 330 through the third elastic member 350. Under the elastic force of the third elastic member 350, the second sub-sleeve 340 slides and extends out of the first sub-sleeve 330 in a direction away from the sound-emitting device 200. Under the action of external force, the second sub-sleeve 340 also slides and shrinks into the first sub-sleeve 330 in a direction close to the sound-emitting device 200. Under the action of external force, the first sub-sleeve 330 also slides and shrinks into the sound outlet channel 120 in a direction close to the sound-emitting device 200.

[0147] When using the earphones of the embodiment of the present application, Fig.12a and Figure 12b As shown, the earplug body 310 can reach the first extension length when the first sub-sleeve 330 extends out of the sound channel 120 and the second sub-sleeve 340 remains in the contracted state. Fig.13a and Fig.13bAs shown, when the second sub-sleeve 340 extends out of the first sub-sleeve 330, the earplug body 310 can reach a second extension length, which is greater than the first extension length. The earplug body 310 reaching the second extension length can be called an in-ear state, and the earplug body 310 reaching the first extension length can be called a semi-in-ear state. By selecting the extension length of the earplug body 310, the earphone 10 can be in a non-in-ear state, a semi-in-ear state, or an in-ear state, so that the earphone 10 is suitable for different situations or different people, and the use range of the earphone 10 is expanded.

[0148] In the embodiment of the present application, the sliding matching structure between the first sub-sleeve 330 and the sound outlet channel 120 can be the same as the sliding matching structure between the sleeve 320 and the sound outlet channel 120 in the first embodiment, the limiting matching structure between the first sub-sleeve 330 and the sound outlet channel 120 can be the same as the limiting matching between the sleeve 320 and the sound outlet channel 120 in the first embodiment, and the limiting matching structure between the first sub-sleeve 330 and the stop bar 520 of the unlocking assembly can also be the same as the limiting matching structure between the sleeve 320 and the stop bar 520 of the unlocking assembly in the first embodiment. This application will not elaborate on this.

[0150] like Figures 14a to 15 As shown, the inner wall of the first sub-sleeve 330 is provided with a third limiting structure 331, which can cooperate with the second sub-sleeve 340 in a contracted state to axially limit the second sub-sleeve 340. Thus, the second sub-sleeve 340 can be kept automatically contracted.

[0151] The third limiting structure 331 can also cooperate with the second sub-sleeve 340 when the second sub-sleeve 340 is extended to axially limit the second sub-sleeve 340. Thus, after the second sub-sleeve 340 is extended, it can be prevented from shrinking after being accidentally touched, so that it remains in the extended state.

[0152] Specifically, the third limiting structure 331 includes a first limiting groove 3311 and a second limiting groove 3312, and the first limiting groove 3311 and the second limiting groove 3312 are sequentially arranged along the sound output direction Z. The outer wall of the second sub-sleeve 340 is provided with a third protrusion 341, and when the second sub-sleeve 340 is in a retracted state, the third protrusion 341 is in a limiting cooperation with the first limiting groove 3311; when the second sub-sleeve 340 is in an extended state, the third protrusion 341 is in a limiting cooperation with the second limiting groove 3312.

[0153] The inner wall of the first sub-sleeve 330 is also provided with a limit release groove 3313, which extends along the axial direction of the first sub-sleeve 330 and is connected with the first limit groove 3311 and the second limit groove 3312. After the second sub-sleeve 340 is rotated, the third protrusion 341 enters the limit release groove 3313 from the first limit groove 3311 or the second limit groove 3312 to release the axial limit of the second sub-sleeve 340.

[0154] In the embodiment of the present application, by providing the first limiting groove 3311, the second sub-sleeve 340 can be limited after it is contracted, so that the second sub-sleeve 340 can keep automatically contracting. By providing the limiting release groove 3313, after the second sub-sleeve 340 is rotated, the third protrusion 341 can enter the limiting release groove 3313 from the first limiting groove 3311, release the limiting of the second sub-sleeve 340, and make the second sub-sleeve 340 extend out of the first sub-sleeve 330 in the limiting release groove 3313 along the sound output direction Z, until the second sub-sleeve 340 contacts the top wall of the limiting release groove 3313, the second sub-sleeve 340 can be rotated again, so that the third protrusion 341 enters the second limiting groove 3312 from the limiting release groove 3313, and keeps the extended state. By providing the second limiting groove 3312, the second sub-sleeve 340 can be limited during the extension process of the second sub-sleeve 340, so as to prevent the second sub-sleeve 340 from shrinking after an accidental touch, so that the second sub-sleeve 340 remains in the extended state. It is understandable that the second sub-sleeve 340 can be switched from the extended state to the retracted state and remain automatically retracted by adopting the reverse process of the above operation process, and this application will not elaborate on this.

[0155] See also Figures 16a to 17b ,in, Fig.16a It is a schematic cross-sectional view of the earphone 10 in the non-in-ear state in the XZ plane according to the fourth embodiment of the first aspect of the present application; Fig.16b for Fig.16a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown; Fig.16c for Fig.16b A magnified schematic diagram of part A; Fig.17a for Fig.16a The schematic cross-sectional view of the earphone 10 in the in-ear state in the XZ plane is shown; Fig.17b for Fig.17a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown.

[0156] like Figures 16a to 17b As shown, in the fourth embodiment of the present application, unlike the first embodiment, the sleeve 320 is not a single tubular structure, but includes a multi-stage sub-sleeve that is nested and matched, wherein the first-stage sub-sleeve 360 ​​is slidably connected to the inner wall of the sound outlet channel 120, and each of the remaining sub-sleeves can be slidably connected to the outer wall of the previous-stage sub-sleeve in the form of a sleeve, and the first end of the last-stage sub-sleeve is connected to the first elastic member 400 and the sound outlet hole 311 of the earplug body 310. Under the elastic force of the first elastic member 400, the last-stage sub-sleeves except the first-stage sub-sleeves slide out relative to the previous-stage sub-sleeve in the direction away from the sound-generating device 200, and the first-stage sub-sleeve 360 ​​slides out relative to the sound-emitting channel 120 in the direction away from the sound-generating device 200; the last-stage sub-sleeves also slide and shrink into the previous-stage sub-sleeves in the direction close to the sound-generating device 200 under the action of external force, and the first-stage sub-sleeve 360 ​​slides and shrinks into the sound-emitting channel 120 in the direction close to the sound-generating device 200. Of course, in other embodiments, the sub-sleeves of each stage may also be nested, which is not limited here.

[0157] By configuring the sleeve 320 to include a plurality of nested multi-stage sub-sleeves, after the sleeve 320 is extended, its extended length is equal to the sum of the sliding distances of the plurality of sub-sleeves, and the extended length is longer. At the same time, after the sleeve 320 is retracted, the plurality of sub-sleeves are nested together, so that the overall length of the sleeve 320 is shorter, so that it can be accommodated in the sound outlet channel 120. Thus, the sleeve 320 can have a larger extended length while meeting the miniaturized design of the earphone 10.

[0158] Specifically, Figures 16a to 17b As shown, in the fourth embodiment, the sleeve 320 includes a first-stage sub-sleeve 360, a second-stage sub-sleeve 370 and a third-stage sub-sleeve 380 which are nested and matched, and the third-stage sub-sleeve 380 is the last-stage sub-sleeve. The first end of each stage of the sub-sleeve is the end away from the sound-generating device 200, and the second end is the end close to the sound-generating device 200.

[0159] See also Figures 18a to 18d ,in Fig.18a for Fig.16a A schematic structural diagram of the middle housing 100; Fig.18b for Fig.16a A schematic structural diagram of the first-stage sub-sleeve 360; Fig.18c for Fig.16a A schematic structural diagram of the middle second stage sub-sleeve 370; Fig.18d for Fig.16a A schematic structural diagram of the middle third-stage sub-sleeve 380.

[0160] like Fig.18a As shown, the inner wall of the sound outlet channel 120 is provided with a second sliding groove 125. Fig.18b As shown, the outer circumference of the second end of the first-stage sub-sleeve 360 ​​is provided with a first retaining ring 361, and the outer circumference of the first retaining ring 361 is provided with a fourth protrusion 362, which is inserted into the second sliding groove 125 and slides with the second sliding groove 125, so that the first-stage sub-sleeve 360 ​​can slide relative to the sound outlet channel 120. The sound outlet channel 120 is provided with a fourth limiting structure, which limits the sliding stroke of the first-stage sub-sleeve 360 ​​in the direction away from the sound-generating device 200. Specifically, as Fig.17b As shown, the side wall of the second sliding groove 125 away from the sound-generating device 200 constitutes a fourth limiting structure, which can slide and limit the fourth protrusion 362, thereby preventing the first-stage sub-sleeve 360 ​​from being separated from the sound outlet channel 120 during the extension process. The outer peripheral surface of the first end of the first sub-sleeve 330 is also provided with a second retaining ring 363.

[0161] like Fig.18c As shown, a third retaining ring 371 is disposed at the second end of the second-stage sub-sleeve 370, and a fourth retaining ring 372 is also disposed on the outer circumference of the first end of the second-stage sub-sleeve 370. Fig.16b and Fig.16c As shown, in the retracted state of the earphone 10, the inner ring portion of the third retaining ring 371 abuts against the first retaining ring 361 of the first-stage sub-sleeve 360, as shown in FIG. Fig.17a As shown, the third retaining ring 371 can slide axially between the first retaining ring 361 and the second retaining ring 363 to achieve a sliding connection between the second-stage sub-sleeve 370 and the first-stage sub-sleeve 360 ​​.

[0162] like Fig.18d As shown, the inner circumference of the second end of the third-stage sub-sleeve 380 is provided with a fifth retaining ring 381, and the outer circumference of the second end of the third-stage sub-sleeve 380 is also provided with a sixth retaining ring 382. Fig.16b and Fig.16c As shown, when the earphone 10 is in the retracted state, the fifth retaining ring 381 abuts against the outer ring portion of the third retaining ring 371, as shown in FIG. Fig.17b As shown, the fifth retaining ring 381 can slide axially between the third retaining ring 371 and the fourth retaining ring 372 to achieve a sliding connection between the third-stage sub-sleeve 380 and the second-stage sub-sleeve 370 .

[0163] In addition, when the second-stage sub-sleeve 370 slides out, the second retaining ring 363 can limit the sliding stroke of the second-stage sub-sleeve 370 in the direction away from the sound-emitting device 200 to prevent the second-stage sub-sleeve 370 from falling out; when the third-stage sub-sleeve 380 slides out, the fourth retaining ring 372 can limit the sliding stroke of the third-stage sub-sleeve 380 in the direction away from the sound-emitting device 200 to prevent the third-stage sub-sleeve 380 from falling out. Therefore, the second retaining ring 363 and the fourth retaining ring 372 constitute a fifth limiting structure for limiting the sliding stroke of the latter-stage sub-sleeve.

[0164] like Fig.16b As shown, the first end of the third-level sub-sleeve 380, which is provided with a sixth retaining ring 382, ​​is connected to the sound outlet 311 of the earplug body 310. The first end of the first elastic member 400 is connected to the bottom wall of the storage groove 130, and the other end of the first elastic member 400 is connected to the sixth retaining ring 382. When the first elastic member 400 pops out, it drives the third-level sub-sleeve 380 and the earplug body 310 to slide out relative to the second-level sub-sleeve 370. The sliding of the third-level sub-sleeve 380 drives the sliding of the second-level sub-sleeve 370 and the first-level sub-sleeve 360 ​​in turn. In this way, each level of sub-sleeves 320 can slide out, so that the earphone 10 can be switched to the following positions: Fig.17a and Fig.17b As shown in the in-ear configuration, after the sub-sleeves 320 of each level slide out, the sub-sleeves 320 of each level can be slid and retracted by pressing, and switched back to the configuration as shown in the in-ear configuration. Fig.16a and Fig.16b Non-in-ear configuration shown.

[0165] like Fig.18a As shown, the inner wall of the sound outlet channel 120 is further provided with a third sliding groove 126. Fig.18d As shown, the outer peripheral surface of the second end of the third-stage sub-sleeve 380 is also provided with a fifth protrusion 383, as shown in FIG. Fig.16a As shown, the fifth protrusion 383 is inserted into the third sliding groove 126 and slides with the third sliding groove 126. The sound outlet channel 120 is provided with a through hole 123, and the through hole 123 is located at one end of the third sliding groove 126 close to the sound device 200. The first protrusion 5211 of the blocking rod 520 can be blocked at the side of the fifth protrusion 383 away from the sound device 200 when the earphone 10 is in the non-in-ear state, thereby preventing the fifth protrusion 383 from sliding along the sound output direction Z, so that the sub-sleeves of each level remain in a contracted state, and the non-in-ear state of the earphone 10 is automatically maintained. Its unlocking method and principle are the same as those in the first embodiment, and will not be repeated here.

[0166] like Fig.16aAs shown, in the embodiment of the present application, the first elastic member 400 can be a conical coil spring. Under the condition of the same extended length, the conical coil spring is shorter after compression than the ordinary cylindrical coil spring. Therefore, it is more suitable for cooperation with the sleeve 320 in the fourth embodiment which has a longer extended length and a shorter length after compression.

[0167] In other embodiments of the present application, the number of stages of the sub-sleeves may be more, such as four, or less, such as two, which is not limited in the present application.

[0168] See also Figures 19a to 19d ,in, Fig.19a Schematic diagram of a cross section of the earphone 10 in the non-in-ear state in the XZ plane according to the fifth embodiment of the first aspect of the present application; Fig.19b for Fig.19a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown; Fig.19c for Fig.19a The schematic diagram of the structure of the earphone 10 is shown (the earplug body 310 is omitted); Fig.19d for Fig.19c The structure diagram of the earphone 10 in the XY plane is shown.

[0169] In the fifth embodiment of the present application, unlike the first embodiment, the earplug assembly 300 does not include a sleeve 320 slidably connected to the sound outlet channel 120, but includes a pleated sleeve 390. The first end of the pleated sleeve 390 is connected to the sound outlet hole 311 of the earplug body 310, and the second end of the pleated sleeve 390 is fixed in the sound outlet channel 120. The pleated sleeve 390 also includes a pleated portion 391, which can be telescopically deformed along the sound outlet direction Z. The first end of the pleated sleeve 390 is connected to the first elastic member 400, and the pleated portion 391 of the pleated sleeve 390 can be stretched and deformed under the elastic force of the first elastic member 400 to extend out of the sound outlet channel 120. The pleated portion 391 of the pleated sleeve 390 can also be pleated and deformed under the action of an external force to shrink into the sound outlet channel 120.

[0170] In the embodiment of the present application, the first elastic member 400 can be used to stretch and deform the pleated portion 391 so that the pleated sleeve 390 extends out of the sound outlet channel 120, thereby realizing the in-ear form of the earphone 10. The pleated portion 391 can be deformed and folded by an external force such as pressing the earplug body 310 and shrinking it into the sound outlet channel 120, thereby realizing the non-in-ear form of the earphone 10.

[0171] Specifically, Fig.19b As shown, a retaining ring 392 is provided at the second end of the pleated sleeve 390, and an annular groove 127 is provided on the inner wall of the sound outlet channel 120 close to the sound-emitting device 200. The retaining ring 392 is clamped in the annular groove 127, so that the second end of the pleated sleeve 390 is fixed in the sound outlet channel 120.

[0172] like Fig.19a As shown, the housing 100 is provided with a sixth limiting structure 160, and the sixth limiting structure 160 cooperates with the first end stop of the pleated sleeve 390 to keep the pleated sleeve 390 in a pleated contracted state in a locked state.

[0173] Specifically, Fig.19c As shown, the sixth limiting structure 160 is a cantilever beam 161 disposed in the receiving groove 130. The cantilever beam 161 includes a vertical portion 162 and a horizontal portion 163, one end of the vertical portion 162 is fixed to the bottom wall of the receiving groove 130, the other end of the vertical portion 162 extends in a direction away from the sound-generating device 200 and is connected to one end of the horizontal portion 163, and the other end of the horizontal portion 163 extends in an axial direction close to the sound outlet channel 120, so as to block the side of the first end of the pleated sleeve 390 away from the sound-generating device 200 when the pleated sleeve 390 is in a contracted state.

[0174] like Fig.19b As shown, the locking assembly 500 includes a button body 510 and a slide bar 550 fixedly connected to the button body 510. The button body 510 is disposed on the housing 100, and is used to put the locking assembly 500 in an unlocked state when pressed, and put the locking assembly 500 in a locked state when not pressed.

[0175] The slide rod 550 is connected to the bottom of the button body 510 and extends into the shell 100. The slide rod 550 enables the sixth limiting structure 160 to be clamped with the pleated sleeve 390 in the locked state, and releases the clamping of the sixth limiting structure 160 and the first end of the pleated sleeve 390 in the unlocked state.

[0176] Specifically, Fig.19c and Fig.19d As shown, one end of the slide bar 550 away from the key body 510 extends into the storage groove 130 and is located on a side of the vertical portion 162 of the cantilever beam 161 close to the sound outlet channel 120. The slide bar 550 includes a flange portion 551, which protrudes in a direction away from the sound outlet channel 120. After the key body 510 is pressed, the flange portion 551 contacts the vertical portion 162 of the cantilever beam 161 and pushes one end of the vertical portion 162 connected to the horizontal portion 163 to move in a direction away from the sound outlet channel 120, so that the horizontal portion 163 is separated from the first end of the pleated sleeve 390.

[0177] In the embodiment of the present application, by providing the cantilever beam 161, the horizontal portion 163 of the cantilever beam 161 can be blocked at the side of the first end of the pleated sleeve 390 away from the sound-generating device 200 in the locked state, so that the pleated sleeve 390 can maintain the pleated contracted state. By pressing the button body 510, the slide bar 550 can be driven to move, so that the flange portion 551 of the slide bar 550 moves and contacts the vertical portion 162 of the cantilever beam 161, and pushes the end of the vertical portion 162 connected to the horizontal portion 163 to move in a direction away from the sound outlet channel 120, thereby separating the horizontal portion 163 from the first end of the pleated sleeve 390, and releasing the position-limiting clamping of the pleated sleeve 390.

[0178] Furthermore, if Fig.19c As shown, the locking assembly 500 further includes a second elastic member 530, one end of the second elastic member 530 is connected to the end of the slide bar 550 away from the key body 510, and the other end of the second elastic member 530 is connected to the side wall of the storage groove 130. The key body 510 automatically resets from the pressed state under the elastic force of the second elastic member 530. By providing the second elastic member 530, the key body 510 can automatically reset after being pressed, which is more convenient to use.

[0179] See also Figures 20a to 20d , Fig.20a This is a schematic structural diagram of the earphone 10 in the in-ear configuration according to the first embodiment of the second aspect of the present application; Fig.20b for Fig.20a The schematic cross-sectional view of the earphone 10 in the YZ plane is shown; Fig.20c for Fig.20a The structure diagram of the earphone 10 shown is in a non-in-ear configuration; Fig.20d for Fig.20c The schematic cross-sectional view of the earphone 10 in the YZ plane is shown.

[0180] like Figures 20a to 20d As shown, in the first embodiment of the second aspect of the present application, the earphone 10 includes a housing 100, a sound-generating device and an earplug assembly 300. The housing 100 is provided with a receiving cavity 110 and a sound outlet channel 120 connected to the receiving cavity 110. The earplug assembly 300 is detachably connected to the housing 100, and the earplug assembly 300 includes an earplug body 310, and the earplug body 310 is provided with a sound outlet hole 311.

[0181] In the embodiment of the present application, by connecting the earplug assembly 300 to the housing 100, a Fig.20a The earphone shown in the figure has an earplug body 310 that can be inserted into the ear canal of a human body for in-ear use. By removing the earplug body 310 from the housing 100, a Fig.20cThe non-in-ear earphone shown in the figure can be used without in-ear earphones by simply attaching the housing 100 to the outer auricle of the human body. Thus, the in-ear form and non-in-ear form of the earphone 10 can be switched by connecting or disassembling the earplug assembly 300 and the housing 100, which is conducive to users choosing a more suitable form of the earphone 10 according to the use scenario and improving the use experience.

[0182] In the first embodiment, the housing 100 is snap-fitted with the earplug body 310 so that the sound outlet hole 311 is connected with the sound outlet channel 120 to form an in-ear earphone. Fig.20b As shown, the outer peripheral surface of the sound outlet channel 120 is provided with an annular groove 128, the earplug body 310 includes a surrounding portion 316 and a cylindrical portion 317, the sound outlet hole 311 is provided on the surrounding portion 316, one end of the cylindrical portion 317 is connected to the surrounding portion 316, and the inner wall of the other end of the cylindrical portion 317 is provided with an annular protrusion 3171. By snapping the annular protrusion 3171 into the annular groove 128, the snap-on connection between the earplug body 310 and the shell 100 can be achieved.

[0183] In other embodiments, Figures 20a to 20d The earphone 10 shown can be used as an earphone body in conjunction with accessories such as an ear hook or a neck hook.

[0184] See also Fig.21 , Fig.21 for Fig.20a In the embodiment of the present application, the earphone 10 further comprises an ear hook 600 connected to the housing 100. When the earphone 10 is used, the ear hook 600 can be hung on the ear of the human body so that the housing 100 fits the outer auricle of the human body. Fig. 9 There is no restriction when using it with neck hanging accessories.

[0185] See also Figures 22a to 23b ,in, Fig.22a Schematic diagram 1 of the structure of the earphone 10 in the in-ear state according to the second embodiment of the second aspect of the present application; Figure 22b for Fig.22a The second structural diagram of the earphone 10 is shown; Fig.23a for Fig.22a A schematic diagram of the earphone 10 for in-ear use is shown; Figure 23b for Fig.23a A schematic diagram of non-in-ear use of the earphone 10 is shown;

[0186] like Figures 22a to 23b As shown, in the second embodiment, Figures 20a to 20d The difference from the first embodiment shown is that the earplug body 310 and the housing 100 are not snap-fitted but sleeved. Figures 22a to 23bAs shown, the earplug assembly 300 further includes a wrapping portion 318, which is connected to the earplug body 310 and is sleeved on the housing 100 so that Fig.23a As shown, the earplug body 310 is located on the sound output direction Z side of the housing 100, forming an in-ear earphone, or, as shown in FIG. Figure 23b As shown, the earplug body 310 is located on a side of the housing 100 that is away from the sound output direction Z, forming a non-in-ear earphone.

[0187] When using the earphone 10 of the embodiment of the present application, the wrapping portion 318 can be mounted on the shell 100, and by adjusting the wrapping portion 318, the earplug body 310 can be located on the sound output direction Z side of the shell 100, so that when in use, the earplug body 310 can enter the ear canal and be used in the ear.

[0188] In the embodiment of the present application, the non-in-ear use of the earphone 10 can be achieved in two ways. The first way is that when using it, the earplug assembly 300 is not installed, and the shell 100 is only attached to the outer auricle of the human body. Thus, the earphone 10 is located outside the ear canal and is not used for in-ear use. The second way is when using it, such as Figure 23b As shown, the wrapping portion 318 is sleeved on the shell 100. By adjusting the wrapping portion 318, the earplug body 310 is located on the side of the shell 100 away from the sound output direction Z. Therefore, when in use, the earplug body 310 is located on the side of the shell 100 away from the human ear and does not enter the ear canal, thereby achieving non-in-ear use.

[0189] In addition, if Figure 22b As shown, the package 318 is provided with an avoidance hole 3181. Figure 23b As shown, when the earplug body 310 is located on the side of the housing 100 away from the sound output direction Z, the avoidance hole 3181 is located on the sound output direction Z side of the housing 100 and avoids the sound output channel 120. Therefore, when the wrapping part is put on the housing 100 and is not used in the ear, the wrapping part will not cover the sound output channel 120.

[0190] It should be noted that Fig.23a and Figure 23b It is only a schematic diagram of the use of the earphone 10 of the second embodiment, wherein the shell 100, the earplug body 310 and other components are all schematic diagrams.

[0191] See also Fig.24 , Fig.24 This is a schematic structural diagram of the earphone 10 according to the third embodiment of the present application.

[0192] In an embodiment of the third aspect of the present application, the earphone 10 includes a housing 100, an earplug assembly 300 and an ear hook 600. The housing 100 is provided with a sound outlet channel (not shown in the figure). The earplug assembly 300 includes an earplug body 310 and a conduit 800 connected to the earplug body 310. One end of the conduit 800 is connected to the sound outlet channel of the housing 100, and the other end of the conduit 800 is connected to the sound outlet hole 311 of the earplug body 310. The conduit 800 includes a pleated deformation portion 810, which can be telescopically deformed and bent to change the position of the earplug body 310, so that the earplug body 310 enters the human ear canal to form an in-ear earphone, or the earplug body 310 is located outside the human ear canal to form a non-in-ear earphone.

[0193] When the earphone 10 of the embodiment of the present application is used, the fold deformation part 810 of the conduit 800 can be elongated and bent so that the earplug body 310 can enter the human ear canal and be used in the ear. The fold deformation part 810 of the conduit 800 can be compressed to shorten its length, so that the earplug body 310 is located outside the ear canal when in use, so that it can be used outside the ear. In this way, it is convenient for users to select the earphone 10 as a non-in-ear form or an in-ear form according to the use scenario, which is conducive to improving the user's use experience.

[0194] Furthermore, the earphone also includes an ear hook 600, which is connected to the shell 100. When in use, the ear hook 600 can be hung on the human ear so that the shell 100 fits the outer auricle of the human body.

[0195] It should be noted that in the examples and description of this patent, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one" do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0196] Although the present application has been illustrated and described with reference to certain preferred embodiments thereof, it will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present application.
