[0043] The following will be described Figures 1-11 An earphone and an earphone assembly according to an embodiment of the present application.

[0044] As Figures 1 to 4 shown, the earphone 100 of some embodiments of the present application comprises an ear-in portion 11, an ear handle portion 12 and a stylus tip 13.

[0045] The ear-in portion 11 and the ear handle portion 12 are rotatably connected, and one of the ear-in portion 11 and the ear handle portion 12 is provided with the stylus tip 13. The stylus tip 13 can interact with the display screen of an electronic device such as a mobile phone or a tablet computer. When the stylus tip 13 contacts the display screen of the electronic device, it will cause the capacitance of the contact point on the display screen to change, so that the stylus tip can input control instructions to the display screen to realize the interaction between the stylus tip and the display screen.

[0046] The earphone 100 has a first state and a second state; in the case where the earphone 100 is in the first state, the extension direction of the ear-in portion 11 intersects the extension direction of the ear handle portion 12; in the case where the earphone 100 is in the second state, the ear-in portion 11 and the ear handle portion 12 extend in the same direction, and the earphone 100 can be used as a stylus.

[0047] In actual application, by rotatably connecting the ear-in portion and the ear handle portion of the earphone, when the earphone is configured in the first state, the user can wear the earphone on the ear and listen to music, and when the earphone is configured in the second state, the earphone is switched from the earphone form to the stylus form, and the user can hold the earphone in the stylus form and perform handwriting input operation on the electronic device based on the stylus tip.

[0048] It should be pointed out here that the earphone 100 shown in the present embodiment can be a true wireless stereo (TWS) earphone.

[0049] In order to realize the normal function of the earphone 100, the ear-in portion 11 and the ear handle portion 12 shown in the present embodiment are rotatably connected, which can be understood as that one end of the ear-in portion 11 and one end of the ear handle portion 12 are rotatably connected through a hinge structure or a spherical joint, and one end of the ear-in portion 11 and one end of the ear handle portion 12 are also electrically connected.

[0050] In the earphone 100, the earphone 100 includes the earphone body 11 and the ear stem 12, and the earphone body 11 and the ear stem 12 are provided with circuit units. For example, the earphone body 11 is provided with an electroacoustic unit, and the ear stem 12 of the earphone 100 is provided with a circuit board, a battery assembly and other circuit units. The electroacoustic unit of the earphone body 11 is electrically connected to the circuit unit of the ear stem 12.

[0051] In this embodiment, in order to switch the earphone 100 between the first state and the second state, the earphone body 11 and the ear stem 12 are electrically connected through a flexible circuit board.

[0052] Further, in order to realize the handwriting input function of the earphone 100 in the stylus mode, the stylus head 13 can be detachably mounted on the end of the earphone body 11 away from the ear stem 12, or the stylus head 13 can be detachably mounted on the end of the ear stem 12 away from the earphone body 11, or the stylus head 13 can be detachably mounted on both the end of the earphone body 11 away from the ear stem 12 and the end of the ear stem 12 away from the earphone body 11.

[0053] In some embodiments, as shown in Figure 1 As shown in Figure 2 In this embodiment, the stylus head 13 is detachably mounted on the end of the ear stem 12 away from the earphone body 11, because the end of the earphone body 11 away from the ear stem 12 is usually provided with an earplug 1301.

[0054] In this embodiment, the stylus head 13 is a positive stylus head, and the stylus head 13 includes a conductive stylus head 1311 and an electronic control unit 1312. The conductive stylus head 1311 is detachably connected to the end of the ear stem 12 away from the earphone body 11 and is electrically connected to the electronic control unit 1312.

[0055] Specifically, the conductive stylus head 1311 includes a stylus head and a stylus tip. The end of the ear stem 12 away from the earphone body 11 is detachably connected to one end of the stylus head by plug-in or threaded connection. At the same time, one end of the stylus tip protrudes from the other end of the stylus head, and the other end of the stylus tip is arranged in the stylus head and is electrically connected to the electronic control unit 1312.

[0056] In this embodiment, the electronic control unit 1312 includes a pressure sensor and a control module. The stylus tip is electrically connected to the pressure sensor, and the stylus tip and the pressure sensor are electrically connected to the control module, respectively.

[0057] In actual application, the pressure sensor is used to detect the pressure information of the stylus tip when the stylus tip contacts the display screen of the electronic device, and the control module is used to transmit the pressure information detected by the pressure sensor to the display screen of the electronic device through the stylus tip, so as to realize the interaction between the stylus head and the display screen.

[0058] As shown in Figure 1As shown, when the earphone 100 is in the first state, the earphone 100 is in earphone form. The setting of the stylus tip 13 shown in this embodiment does not affect the music playback function of the earphone 100.

[0059] like Figure 2 As shown, when the earphone 100 is in the second state, the earphone 100 is in a straight line shape and takes the form of an active stylus. When the user holds the earphone 100, they can input control commands to the display screen of the electronic device through the stylus tip 13.

[0060] In some embodiments, such as Figure 1 and Figure 2 As shown, in this embodiment of the application, the ear stem 12 and the stylus tip 13 are connected to a threaded adapter via a threaded hole.

[0061] In this embodiment, a threaded hole can be provided at the end of the ear stem 12 away from the ear inlet 11, and a threaded adapter can be provided at the end of the stylus tip 13. Alternatively, a threaded adapter can be provided at the end of the ear stem 12 away from the ear inlet 11, and a threaded hole can be provided at the end of the stylus tip 13, so that the connection between the ear stem 12 and the stylus tip 13 can be realized based on the threaded connection of the threaded hole and the threaded adapter.

[0062] Furthermore, the threaded adapter of this application embodiment can be assembled at a first depth position and a second depth position within a threaded hole.

[0063] At the first depth position, the earphone 100 reaches the first length in the second state; at the second depth position, the earphone 100 reaches the second length in the second state, and the first length is greater than the second length.

[0064] Thus, when the earphone 100 is configured in the second state, since the earphone 100 can be used as a stylus, the length of the stylus can be adjusted by adjusting the depth of the threaded adapter within the threaded hole. In some embodiments, such as Figure 3 and Figure 4 As shown, in this embodiment of the application, an earplug 1301 is provided at the end of the earpiece 11 away from the ear stem 12. Here, the earplug 1301 shown in this embodiment is made of a conductive material to serve as the aforementioned stylus tip 13.

[0065] In this embodiment, an internal thread structure may be provided at the end of the ear stem 12 away from the ear stem 12, and the ear stem 12 may be detachably connected to the above-mentioned stylus tip 13 based on the internal thread structure.

[0066] In this embodiment, the ear inlet 11 is provided with an external thread structure at the end away from the ear stem 12, and an internal thread structure is provided on the earplug 1301. Based on the threaded engagement between the external thread structure and the internal thread structure on the earplug 1301, the ear inlet 11 and the earplug 1301 are connected.

[0067] Meanwhile, the earplug 1301 in this embodiment is made of a conductive material based on POM (Paraformaldehyde, polyoxymethylene).

[0068] As shown in Figure 3 , when the earphone 100 is in the first state, the earphone 100 assumes an earphone shape, and the earplug 1301 in this case is mainly used to ensure the comfort of the user wearing the earphone and prevent the electro-acoustic unit 111 built in the ear-in portion 11 from emitting sound too loudly to cause harm to the human body.

[0069] As shown in Figure 4 , when the earphone 100 is in the second state, the earphone 100 assumes a straight line shape and assumes the shape of a passive stylus, and the user can hold the earphone 100 and input control instructions to the display screen of the electronic device through the earplug 1301.

[0070] In some embodiments, as shown in Figures 1 to 4 , when the earphone 100 is in the stylus shape, in order to facilitate the user's hand operation, the ear-in portion 11 and the ear handle portion 12 in this embodiment are both designed as a column shape. For example, the ear-in portion 11 and the ear handle portion 12 are both cylindrical.

[0071] In this way, when the user needs to use the earphone 100 to listen to music, the user can manually pull the ear-in portion 11 and the ear handle portion 12 to rotate relative to each other to configure the earphone 100 to the first state. At this time, the ear-in portion 11 and the ear handle portion 12 assume an opening angle of 90°, and the central axis of the ear-in portion 11 is perpendicular to the central axis of the ear handle portion 12, so as to facilitate the user's ear to wear the earphone 100.

[0072] When the user needs to use the stylus function of the earphone 100, the user can manually pull the ear-in portion 11 and the ear handle portion 12 to rotate relative to each other to configure the earphone 100 to the second state. At this time, the ear-in portion 11 and the ear handle portion 12 assume an opening angle of 180° and are coaxially arranged, so as to facilitate the user to hold the earphone 100 in the stylus shape.

[0073] In some embodiments, in order to facilitate the user to hold the earphone 100 in the stylus shape, the earphone 100 in this embodiment further comprises a flexible sleeve 14, which is sleeved on the peripheral surface of the ear handle portion 12.

[0074] Among them, the flexible sleeve 14 in this embodiment is preferably a silica gel sleeve. This embodiment can also be provided with a plurality of protrusions on the outer side of the flexible sleeve 14 to facilitate the user's hand operation.

[0075] In some embodiments, the earphone 100 shown in the embodiment has an in-ear part 11 provided with an electro-acoustic unit 111 and an ear stem part 12 provided with a battery assembly 121. To meet the charging requirement of the battery assembly 121, the embodiment has a first charging contact 122 provided on the side wall of the ear stem part 12.

[0076] Correspondingly, the electro-acoustic unit 111 shown in the embodiment is electrically connected with the battery assembly 121, and the battery assembly 121 is electrically connected with the first charging contact 122.

[0077] In the embodiment, the first charging contact 122 includes a positive contact and a negative contact, and the positive contact and the negative contact are connected with the positive and negative poles of the battery assembly 121 one by one.

[0078] As shown in Figure 5 As shown in Figure 6 The earphone 100 shown in the embodiment includes a left earphone 101 and a right earphone 102. When the earphone 100 is used as a stylus, in order to facilitate the user to hold the stylus, the embodiment can combine the left earphone 101 and the right earphone 102.

[0079] Specifically, when the left earphone 101 and the right earphone 102 are both configured in the second state, the in-ear part 11 of the left earphone 101 and the ear stem part 12 of the right earphone 102 are detachably connected, and the ear stem part 12 of the left earphone 101 is provided with a stylus head 13 at the end away from the in-ear part 11, so that the left earphone 101 and the right earphone 102 form the stylus.

[0080] In the embodiment, the in-ear part 11 of the left earphone 101 and the ear stem part 12 of the right earphone 102 can be threadedly connected, the ear stem part 12 of the left earphone 101 is threadedly connected with the stylus head 13 at the end away from the in-ear part 11, and the in-ear part 11 of the right earphone 102 is threadedly connected with an earplug 1301 at the end away from the ear stem part 12.

[0081] In this way, the left earphone 101 and the right earphone 102 form the stylus based on the embodiment. When the earplug 1301 is made of conductive material, the user can perform handwriting input operation on the display screen of the electronic device through the stylus head 13 at one end of the stylus, or perform handwriting input operation on the display screen of the electronic device through the earplug 1301 at the other end of the stylus, which is simple and convenient.

[0082] As shown in Figure 7 As shown in Figure 8 The earphone 100 shown in the embodiment includes a left earphone 101 and a right earphone 102. When the earphone 100 is used as a stylus, in order to facilitate the user to hold the stylus, the embodiment can combine the left earphone 101 and the right earphone 102.

[0083] Specifically, in the case that the left earphone 101 and the right earphone 102 are both in the second state, the ear stem 12 of the left earphone 101 is detachably connected with the ear stem 12 of the right earphone 102, and the in-ear part 11 of at least one of the left earphone 101 and the right earphone 102 is provided with the stylus tip 13, so that the left earphone 101 and the right earphone 102 constitute the stylus.

[0084] In this embodiment, the ear stem 12 of the left earphone 101 is threadedly connected with the ear stem 12 of the right earphone 102, and the in-ear part 11 of the left earphone 101 and the in-ear part 11 of the right earphone 102 are both threadedly connected with the earplug 1301. The earplug 1301 is made of conductive material and serves as the stylus tip 13.

[0085] In this way, the left earphone 101 and the right earphone 102 constitute the stylus in this embodiment, and the user can perform handwriting input operation on the display screen of the electronic device through the earplugs 1301 at both ends of the stylus, which is simple and convenient.

[0086] Of course, a plurality of left earphones 101 and a plurality of right earphones 102 can also constitute the stylus in this embodiment, which will not be described one by one here.

[0087] In some embodiments, as shown in Figures 9 to 11 The earphone assembly also includes the earphone charging box 200 and the earphone 100 as described above.

[0088] The earphone charging box 200 is provided with a charging compartment, and the earphone 100 is adapted to the charging compartment. In the case that the earphone 100 is in the first state, the earphone 100 can be stored in the charging compartment.

[0089] In this embodiment, the earphone assembly includes the earphone 100, and the specific structure of the earphone 100 is referred to the above embodiments. Therefore, the earphone assembly in this embodiment includes all the technical solutions of the above embodiments, and at least has all the beneficial effects brought by all the technical solutions of the above embodiments, which will not be described one by one here.

[0090] In actual application, since the earphone 100 usually includes the left earphone 101 and the right earphone 102, the charging compartment in this embodiment includes the first charging compartment 201 and the second charging compartment 202.

[0091] The left earphone 101 is adapted to the first charging compartment 201, and the inner wall of the first charging compartment 201 is provided with the second charging contact 211, which is electrically connected with the first charging contact 122 on the left earphone 101.

[0092] The right earphone 102 is adapted to the second charging bin 202, and the inner wall of the second charging bin 202 is provided with a third charging contact 221 which is electrically connected with the first charging contact 122 on the right earphone 102.

[0093] Here, the embodiment is based on the arrangement of the earphone charging box 200, and the left earphone 101 and the right earphone 102 are stored and charged at the same time.

[0094] As shown in Figure 10 As shown in Figure 11 Since the end of the ear handle part 12 of the left earphone 101 away from the earphone charging box 200 can be detachably connected with the end of the ear handle part 12 of the right earphone 102 away from the earphone charging box 200, and the ear handle part 12 and the ear handle part 12 of the two earphones are rotatably connected, after the two earphones are charged, the user only needs to manually pull the end of the ear handle part 12 of the two earphones away from the earphone charging box 200 to switch the two earphones from the first state to the second state, so that the two earphones can be conveniently taken out of the earphone charging box 200, which is simple and convenient to operate.

[0095] In some embodiments, the first charging bin 201 shown in the embodiment is arranged on the first side P1 of the earphone charging box 200, and the second charging bin 202 is arranged on the second side P2 of the earphone charging box 200, and the second side P2 is opposite to the first side P1.

[0096] Specifically, compared with the storage mode of the existing earphone 100 in the earphone charging box 200, the embodiment improves the arrangement position of the two charging bins on the earphone 100 and the earphone charging box 200, omits the traditional cover plate on the earphone charging box 200 for covering the charging bin, reduces the overall size of the earphone charging box 200, and facilitates the taking out of the left earphone 101 from the first charging bin 201 and the right earphone 102 from the second charging bin 202.

[0097] At the same time, in order to further reduce the design size of the earphone charging box 200, the first charging bin 201 and the second charging bin 202 are arranged to be centrally symmetrically distributed with respect to the center of the earphone charging box 200.
