[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0043] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. The technical solutions in the embodiments of this application will now be described in conjunction with the accompanying drawings.

[0044] It should be noted that, for ease of explanation, the same reference numerals denote the same components in the embodiments of this application, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0045] Before introducing the headphones provided in the embodiments of this application, headphones in related technologies will be introduced first. It is understood that the headphones in related technologies are headphones prior to the improvements in the embodiments of this application, and should not be construed as headphones in the prior art.

[0046] Please see Figure 1 , Figure 1This is a schematic diagram of an earphone in the related art. The earphone 1 in the related art typically includes a first part 110, a connecting part 130, and a second part 120. The first part 110 has a speaker 111; therefore, the first part 110 is also called a sound-emitting ball or a listening ball. The connecting part 130 connects the first part 110 and the second part 120 respectively. The connecting part 130 is also called a connecting bridge. The second part 120 has a battery; therefore, the second part 120 is also called a battery bean or a power compartment. Furthermore, the earphone 1 in the related art also has a functional module 150 (such as a touch module or an antenna) in the second part 120. Because the second part 120 of the earphone 1 also has a functional module 150, the second part 120 is relatively large, resulting in a poor wearing experience.

[0047] Furthermore, in related technologies, if the functional module 150 includes a touch module 151, the touch module 151 is used to sense user operations to realize interaction between the earphone 1 and the electronic device. In related technologies, if the earphone 1 is worn on the user's ear, the first part 110 is located in the concha of the ear, and the second part 120 is located at the back of the ear. Therefore, in the related technologies, when the earphone 1 is worn on the user's ear, if the user wants to operate the functional area of ​​the touch module 151 corresponding to the second part 120, they need to reach their hand to a relatively far back position to operate the functional area. Thus, in the related technologies, the earphone 1 is not easily operated when worn on the user's ear.

[0048] This application provides a connector 300 and an earphone 1. The connector 300 and earphone 1 provided in this application will be described in detail below. The earphone 1 can be, but is not limited to, an open-ear wearable stereo (OWS) earphone 1 or a neckband earphone 1. The OWS earphone 1 can be a clip-on earphone 1 (see...). Figure 2 It can also be an ear-hook type of headphone 1 (see...) Figure 21 The OWS headphones 1 do not block the ear canal when worn, and transmit sound through air conduction / bone conduction, providing better comfort for extended wear. Figure 21 In this application, the earphone 1 is an ear-hook type earphone. In the other figures of this application, the earphone 1 is illustrated as an example of an ear clip type earphone 1. It can be understood that the earphone 1 shown in the figure is only one form of the earphone 1 in this application and should not be construed as a limitation on the earphone 1 of the embodiments of this application.

[0049] Please refer to the following: Figure 2 , Figure 3 and Figure 4 , Figure 2 A perspective view of the headphones provided according to one embodiment of this application; Figure 3One implementation method Figure 2 A schematic diagram of the cross-sectional structure of the earphone along line II shown; Figure 4 for Figure 3 A schematic diagram of a flexible circuit board. (For ease of illustration) Figure 4 The circuit board body 1401 of the flexible circuit board 140 is shown in a flattened state for illustration purposes. It should be understood that this should not be construed as a limitation on the embodiments of this application.

[0050] The earphone 1 includes a first part 110, a second part 120, and a connector 300. The connector 300 is used to connect the first part 110 and the second part 120. It is understood that the earphone 1 shown in the embodiments of this application is an introduction to one application scenario of the connector 300, and the structure of the connector 300 in the earphone 1 should not be construed as a limitation on the connector 300 provided in the embodiments of this application.

[0051] Specifically, the connector 300 includes a connecting portion 130 and a flexible circuit board 140. The flexible circuit board 140 is supported on the connecting portion 130. The flexible circuit board 140 includes a circuit board body 1401 and a functional module 150. The circuit board body 1401 has one or more functional regions 140a, which are disposed corresponding to the connecting portion 130. The functional module 150 is disposed in the functional region 140a.

[0052] Specifically, the connecting portion 130 has a first end 1311 and a second end 1312, the first end 1311 being connected to the first portion 110, and the second end 1312 being connected to the second portion 120. The circuit board body 1401 has a functional area 140a (in Figure 3 The functional area 140a (located in the region between the two dotted lines) corresponds to the connecting portion 130. The functional module 150 is disposed in the functional area 140a. In one embodiment, the functional module 150 includes at least one of a touch module 151 and an antenna; however, it is not limited to this. Figure 4 The illustration is based on the functional module 150 including the touch module 151, and it should be understood that it should not be construed as a limitation on the implementation of this application.

[0053] In one embodiment, the earphone 1 is an OWS earphone 1, the first part 110 includes one of a speaker 111 and a battery 121, and the second part 120 includes the other of a speaker 111 and a battery 121.

[0054] In this embodiment, the earphone 1 is an OWS earphone 1. The illustration is based on the example of the first part 110 including a speaker 111 and the second part 120 including a battery 121. This should not be construed as limiting the scope of the embodiments described in this application. Therefore, in this embodiment, the first part 110 is also referred to as a sound-emitting ball, a listening ball, or an acoustic part; the second part 120 is also referred to as a battery bead or an energy capsule. In another embodiment, the first part 110 is a sound-emitting ball, a listening ball, or an acoustic part; the second part 120 is merely a clamping component. In this embodiment, if the earphone 1 is worn on a wearer (such as a human ear), the first part 110 is located in the concha of the ear, and the second part 120 is located on the back of the ear.

[0055] In one embodiment, the initial distance between the first part 110 and the second part 120 is less than the minimum thickness of the ear. Therefore, when the earphone 1 is worn on the ear, the ear will push the first part 110 and the second part 120 apart, increasing the distance between the first part 110 and the second part 120. This increases the outward force applied to both ends of the connecting part 130, causing the connecting part 130 to generate a restoring force that brings them closer together. Under the action of this restoring force, the first end 1311 and the second end 1312 of the connecting part 130 generate a clamping force that brings them closer together, thereby making the first part 110 and the second part 120 tighten on the opposite sides of the ear, so that the earphone 1 is not easy to fall off when worn on the ear.

[0056] In another embodiment, the earphone 1 is an OWS earphone 1, the first part 110 includes a battery 121, and the second part 120 includes a speaker 111; correspondingly, the first part 110 is also called a battery bead or energy capsule, and the second part 120 is also called a sound-emitting ball or listening ball, or an acoustic part. In this embodiment, if the earphone 1 is worn on a wearer (such as a human ear), the first part 110 is located behind the ear, and the second part 120 is located in the concha of the ear.

[0057] If the earphone 1 is a neckband earphone 1, at least one of the first part 110 and the second part 120 includes a speaker 111. In one embodiment, both the first part 110 and the second part 120 include a speaker 111.

[0058] It is understood that the earphone 1 provided in this application does not limit the components included in the first part 110 and the second part 120, as long as the earphone 1 includes the first part 110 and the second part 120.

[0059] In one embodiment, the connecting portion 130 has a first end 1311 and a second end 1312, the first end 1311 being connected to the first portion 110 and the second end 1312 being connected to the second portion 120.

[0060] In one embodiment, the connecting portion 130 has an arc-shaped structure; therefore, the connecting portion 130 is also referred to as a connecting bridge. Along the extending direction of the connecting portion 130, the radii of curvature of the connecting portion 130 may be equal or unequal. In this embodiment, the first end 1311 and the second end 1312 are disposed opposite each other, and the first part 110 and the second part 120 are located on the same side of the connecting portion 130, and the first part 110 and the second part 120 are disposed opposite each other. The first part 110, the connecting portion 130, and the second part 120 are generally arc-shaped, C-shaped, U-shaped, or teardrop-shaped, etc.

[0061] The first part 110, the connecting part 130, and the second part 120 define a wearing space 1a, which is used to wear the device on a wearer. Optionally, if the earphone 1 is an OWS earphone 1, the wearer can be, but is not limited to, a human ear or an ear model. It can be understood that if the earphone 1 is a neckband earphone 1, the wearer can be, but is not limited to, a human neck and a human ear, or a neck model and an ear model.

[0062] The circuit board body 1401 has a functional area 140a, which is provided corresponding to the connection part 130. Specifically, the functional area 140a is provided for part of the connection part 130, or the functional area 140a is provided for all of the connection part 130.

[0063] exist Figure 3 and Figure 4 In the schematic diagram shown, the functional area 140a of the circuit board body 1401 corresponds to a portion of the connecting portion 130, and the portion of the connecting portion 130 near the first portion 110 is used as an example. It should be understood that this should not be construed as a limitation on the headphone 1 provided in the embodiments of this application.

[0064] The flexible circuit board 140 of the connector 300 includes a functional module 150, which is disposed in the functional region 140a. The functional region 140a corresponds to the connecting portion 130; therefore, the functional module 150 corresponds to the connecting portion 130. The functional module 150 may correspond to a portion of the connecting portion 130, or it may correspond to all of the connecting portion 130; this application does not limit this.

[0065] In one embodiment, the functional area 140a may correspond to any segment of the connecting portion 130.

[0066] The functional area 140a is set to correspond to any segment of the connecting part 130, which makes it easier to set the functional area 140a in the connecting part 130.

[0067] In this embodiment, the flexible circuit board 140 of the connector 300 includes a circuit board body 1401 and a functional module 150. In one embodiment, the functional module 150 includes a touch module 151 and an antenna 152 (see [link to antenna 152]). Figure 17 At least one of the following. For example, the functional module 150 includes a touch module 151; or, the functional module 150 includes an antenna 152; or, the functional module 150 includes both a touch module 151 and an antenna 152. It is understood that in other embodiments, the functional module 150 is not limited to at least one of the touch module 151 and the antenna 152.

[0068] The connector 300 provided in this application includes a connecting portion 130 and a flexible circuit board 140. The flexible circuit board 140 includes a circuit board body 1401 and a functional module 150. The circuit board body 1401 has one or more functional regions 140a, which are corresponding to the connecting portion 130. The functional module 150 is disposed in the functional region 140a. Therefore, in the connector 300 provided in this application, the functional module 150 can fully utilize the space of the connector 300, enabling the connector 300 to have the functions of the functional module 150. Compared to related technologies where the functional module 150 is located in the first part 110 or the second part 120 of the earphone 1, if the connector 300 provided in this application is applied to the earphone 1, the volume of the first part 110 and the second part 120 of the earphone 1 to which the connector 300 is applied can be reduced, which is beneficial to improving the wearing experience of the earphone 1 to which the connector 300 is applied.

[0069] Accordingly, an embodiment of this application provides an earphone 1, which includes a first part 110, a second part 120, and a connector 300. In the connector 300, the functional module 150 is disposed in the functional area 140a of the flexible connecting part 130, and the functional area 140a is disposed corresponding to the connecting part 130. Therefore, the functional module 150 can make full use of the space of the connecting part 130, and the functional module 150 does not occupy the volume of the first part 110 and the second part 120 of the earphone 1, thereby making the volume of the first part 110 and the second part 120 of the earphone 1 smaller, and the appearance of the earphone 1 more compact.

[0070] Furthermore, since the first part 110 and the second part 120 of the earphone 1 provided in this embodiment are relatively small, the wearing experience is better when the earphone 1 is worn by the wearer. Even further, if the functional module 150 includes a touch module 151, when the earphone 1 is worn by the wearer, the user can operate the touch module 151 by manually operating the connection part 130 corresponding to the operation area of ​​the touch module 151. This facilitates user operation of the touch module 151.

[0071] Further, in one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 , Figure 5 One implementation method Figure 3 A detailed schematic diagram of the earphones is shown. In one embodiment, the connecting portion 130 has a first sub-connecting portion 130a, a second sub-connecting portion 130b, and a third sub-connecting portion 130c. The first sub-connecting portion 130a and the second sub-connecting portion 130b are disposed opposite to each other, and the third sub-connecting portion 130c is connected between the first sub-connecting portion 130a and the second sub-connecting portion 130b. The functional area 140a includes a touch area 141a, the touch module 151 is located in the touch area 141a, and the touch area 141a is disposed corresponding to at least one of the first sub-connecting portion 130a and the third sub-connecting portion 130c.

[0072] Specifically, in this embodiment, the first part 110 including a speaker 111 is used as an example for illustration. It should be understood that the first part 110 should not be construed as a limitation on the connector 300 provided in this application embodiment. The connecting part 130 has a first end 1311 and a second end 1312, the first end 1311 and the second end 1312 are disposed opposite to each other, the first end 1311 is connected to the first part 110, and the second end 1312 is connected to the second part 120. The connecting part 130 has a vertex P0 away from the first end 1311 and the second end 1312. In one embodiment, the connecting part 130 has a first sub-connecting part 130a, a second sub-connecting part 130b, and a third sub-connecting part 130c. The first sub-connecting part 130a is located on the side of the vertex P0 closer to the first part 110. The second sub-connecting part 130b is located on the side of the vertex P0 closer to the second part 120. The third sub-connection portion 130c connects the first sub-connection portion 130a and the second sub-connection portion 130b, and the third sub-connection portion 130c has the vertex P0.

[0073] The functional area 140a includes a touch area 141a. Correspondingly, the functional module 150 includes a touch module 151. The touch module 151 is located in the touch area 141a, and the touch area 141a is disposed corresponding to at least one of the first sub-connection portion 130a and the third sub-connection portion 130c.

[0074] In one embodiment, the lengths of the first sub-connecting portion 130a, the second sub-connecting portion 130b, and the third sub-connecting portion 130c are all equal or approximately equal. Figure 5 In the diagram, L11 indicates the boundary between the first sub-connecting portion 130a and the second sub-connecting portion 130b, and L12 indicates the boundary between the second sub-connecting portion 130b and the third sub-connecting portion 130c. In this embodiment, the first sub-connecting portion 130a is also referred to as the front section of the connecting portion 130, the second sub-connecting portion 130b is also referred to as the rear section of the connecting portion 130, and the third sub-connecting portion 130c is also referred to as the middle section of the connecting portion 130.

[0075] The vertex P0 of the connecting part 130 is either the midpoint of the connecting part 130 or a non-midpoint of the connecting part 130. This application does not limit this to either.

[0076] The touch module 151 is located in the touch area 141a, and the touch area 141a is configured corresponding to at least one of the first sub-connection portion 130a and the third sub-connection portion 130c. Specifically, in one embodiment, the touch area 141a is configured corresponding to the first sub-connection portion 130a. In another embodiment, the touch area 141a is configured corresponding to the third sub-connection portion 130c. In yet another embodiment, a portion of the touch area 141a is configured corresponding to the first sub-connection portion 130a, and another portion of the touch area 141a is configured corresponding to the third sub-connection portion 130c. The first part 110 has a speaker 111, therefore, the first part 110 is also called a sound-emitting ball or a listening ball, or an acoustic part. In this embodiment, if the earphone 1 is worn on a wearer (such as a human ear), the first part 110 is located in the concha of the ear. Therefore, when the earphone 1 provided in this embodiment is worn on a human ear, the first sub-connecting portion 130a is further forward than the second sub-connecting portion 130b, making it easier for the user to touch. The third sub-connecting portion 130c is further away from the first portion 110 and the second portion 120 than both the first and second sub-connecting portions 130a and 130b. Thus, when the earphone 1 provided in this embodiment is worn on a human ear, the third sub-connecting portion 130c is easier for the user to touch than both the first and second sub-connecting portions 130a and 130b. In this embodiment, the functional module 150 includes a touch module 151. The touch area 141a is provided corresponding to at least one of the first sub-connection portion 130a or the third sub-connection portion 130c. When the earphone 1 is worn, the user can easily operate the touch module 151 by manually operating the corresponding operation area of ​​the touch module 151. This facilitates user operation of the touch module 151.

[0077] Please refer to the following: Figure 6 and Figure 7 , Figure 6 for Figure 3 Detailed illustration of the markings; Figure 7 for Figure 2A partial structural schematic diagram of a cross-section along line II-II. In this embodiment, the connecting portion 130 includes a connecting shell 131. The connecting portion 130 has a first end 1311 and a second end 1312. The first end 1311 has a first end face 1311a, and the second end 1312 has a second end face 1312a. The connecting shell 131 has a through hole 130d, which penetrates the first end face 1311a and the second end face 1312a. The flexible circuit board 140 is received in the through hole 130d, and a gap 130e exists between the flexible circuit board 140 and the inner wall of the connecting shell 131 defining the through hole 130d.

[0078] The connecting portion 130 includes the connecting shell 131, which is used to connect the first portion 110 and the second portion 120. The connecting shell 131 connects the first portion 110 and the second portion 120, either by directly connecting the first portion 110 and the second portion 120 or by indirectly connecting the first portion 110 and the second portion 120.

[0079] In this embodiment, the first end 1311 has a first end face 1311a, and the second end 1312 has a second end face 1312a. The through hole 130d passes through the first end face 1311a and the second end face 1312a. The flexible circuit board 140 is bendable and can be well adapted to the shape of the connecting shell 131.

[0080] The flexible circuit board 140 is housed in the through hole 130d, which gives the earphone 1 a better appearance and also protects the flexible circuit board 140 and the touch module 151 by the connecting shell 131, reducing the probability of damage to the flexible circuit board 140 and the touch module 151.

[0081] There is a gap 130e between the flexible circuit board 140 and the inner wall of the connecting shell 131 that defines the wire hole 130d. Therefore, when the earphone 1 is assembled, the flexible circuit board 140 can be easily inserted into the wire hole 130d of the connecting shell 131.

[0082] In one embodiment, the cross-sectional dimensions of the wire hole 130d are typically 0.1mm to 0.4mm larger, or approximately 0.1mm to 0.4mm larger, than the cross-sectional dimensions of the flexible circuit board 140. This allows the flexible circuit board 140 to be more easily inserted into the wire hole 130d.

[0083] Furthermore, please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 6 In this embodiment, the connecting shell 131 has an inner surface 131a and an outer surface 131b that are disposed opposite to each other. The touch module 151 faces the outer surface 131b.

[0084] The first part 110, the connecting part 130, and the second part 120 define a wearing space 1a. When the earphone 1 is worn by a wearer, the wearing space 1a is used to accommodate the wearer. The inner surface 131a of the connecting shell 131 is the surface of the connecting shell 131 that defines the wearing space 1a, and the outer surface 131b of the connecting shell 131 is the surface of the connecting shell 131 that faces away from the wearing space 1a.

[0085] When the earphone 1 is worn by a wearer, the outer surface 131b is away from the wearer compared to the inner surface 131a. In other words, the inner surface 131a is the surface facing the wearer when the earphone 1 is worn by the wearer, and the outer surface 131b is the surface away from the wearer when the earphone 1 is worn by the wearer.

[0086] The touch module 151 faces the outer surface 131b, thereby facilitating the operation of the touch module 151 by the user wearing the earphone 1 when the earphone 1 is worn on the wearer.

[0087] Furthermore, please refer to the following: Figure 4 , Figure 8 , Figure 9 and Figure 10 , Figure 8 As another implementation method Figure 2 A schematic cross-sectional view of the headphones along line II shown in the diagram; Figure 9 Another implementation Figure 2 A schematic cross-sectional view of the headphones along line II shown in the diagram; Figure 10 This is a schematic diagram of a compressible elastic element provided in one embodiment. In this embodiment, the connector 300 further includes a compressible elastic element 160. The compressible elastic element 160 is fixed to the side of the flexible circuit board 140 opposite to the outer surface 131b. The compressible elastic element 160 is disposed corresponding to the touch area 141a. The compressible elastic element 160 is received in the wire hole 130d, and the compressible elastic element 160 is in a compressed state within the wire hole 130d.

[0088] During the assembly of the connector 300, in order to smoothly insert the flexible circuit board 140 into the wiring hole 130d, the cross-sectional dimensions of the wiring hole 130d are typically larger than the cross-sectional dimensions of the flexible circuit board 140. The flexible circuit board 140 may wobble or loosen within the wiring hole 130d. If the flexible circuit board 140 wobbles or loosens within the wiring hole 130d, the distance between the touch module 151 located in the touch area 141a of the flexible circuit board 140 and the outer wall of the connecting shell 131 defining the wiring hole 130d will be inconsistent, resulting in a problem with the consistency of touch sensitivity. That is, if the distance between the touch module 151 located in the touch area 141a of the flexible circuit board 140 and the outer wall of the connecting shell 131 defining the wiring hole 130d is inconsistent, it will lead to inconsistent touch sensitivity. The area of ​​the flexible circuit board 140 where the touch module 151 is set is the touch area 141a, also known as the FPC touch sensing area. The connecting part 130 is also known as the connecting bridge. Therefore, it can also be said that the distance between the FPC touch sensing area and the outer wall of the connecting bridge that defines the wire hole 130d is not consistent, resulting in a problem of inconsistent touch function sensitivity.

[0089] The connector 300 provided in this embodiment further includes a compressible elastic element 160, which may include, but is not limited to, a soft, compressible, deformable adhesive, such as foam adhesive. In this embodiment, one of the two opposing surfaces of the compressible elastic element 160 is adhesive, while the other opposing surface is not adhesive. The adhesiveness (also referred to as stickiness) of one of the opposing surfaces of the compressible elastic element 160 is for bonding to the flexible circuit board 140, while the non-adhesiveness of the other opposing surface prevents the compressible elastic element 160 from bonding to the inner wall of the connecting shell 131 defining the wiring hole 130d, so that the compressible elastic element 160 is inserted into the wiring hole 130d along with the flexible circuit board 140.

[0090] Further, as described above, the connecting shell 131 includes an inner surface 131a and an outer surface 131b arranged opposite to each other. The touch module 151 is closer to the outer surface 131b than the circuit board body 1401. One of the two opposite surfaces of the compressible elastic member 160, which is adhesive, faces the outer surface 131b, while the other opposite surface of the compressible elastic member 160, which is non-adhesive, faces the inner surface 131a. The non-adhesive surface of the compressible elastic member 160 facing the inner surface 131a is also referred to as the non-adhesive surface of the compressible elastic member 160 facing the non-touch function side of the connecting shell 131.

[0091] In one embodiment, during the assembly of the connector 300, the compressible elastic member 160 is inserted into the wiring hole 130d along with the flexible circuit board 140. After the flexible circuit board 140 is wired, since one side of the compressible elastic member 160 is fixed to the flexible circuit board 140, the compressible elastic member 160 deforms and expands, holding the flexible circuit board 140 against the inner wall of the connecting shell 131 that defines the wiring hole 130d, which is in close contact with or approximately in close contact with the inner wall of the connecting shell 131. In this way, the distance and relative position between the outer surface 131b of the connecting shell 131 and the surface of the flexible circuit board 140 where the touch module 151 is located (also called the FPC functional surface) are consistent, thereby improving the consistency of touch function sensing and reducing or eliminating situations where the touch is sensitive at times and unresponsive at others.

[0092] exist Figure 8 The diagram illustrates the configuration of the compressible elastic element 160 corresponding to the touch area 141a as an example. Figure 8 and Figure 9 In the diagram, boundaries L21 and L22 are used to indicate the boundaries of the touch area 141a. Figure 9 The diagram illustrates the case where the compressible elastic element 160 is configured corresponding to the touch area 141a, and is configured to correspond to other areas outside the touch area 141a.

[0093] In summary, the connector 300 provided in this application has the compressible elastic member 160 fixed to one side of the flexible circuit board 140, facilitating the insertion of the compressible elastic member 160 into the wiring hole 130d along with the flexible circuit board 140. The compressible elastic member 160 accommodates the wiring hole 130d, and is in a compressed state within the wiring hole 130d. Therefore, the compressible elastic member 160 can hold the portion of the flexible circuit board 140 having the touch area 141a against the inner wall of the connecting shell 131 that defines the wiring hole 130d, conforming to or approximately conforming to it. Thus, the distance between the touch module 151 located in the touch area 141a of the flexible circuit board 140 and the outer surface 131b of the connecting shell 131 that defines the through hole 130d is relatively consistent, thereby ensuring that the distance and relative position between the flexible circuit board 140 and the outer surface 131b of the connecting shell 131 are consistent, and the touch sensing consistency of the touch module 151 is relatively good.

[0094] Please see Figure 4 , Figure 8 , Figure 9 and Figure 10 The compressible elastic element 160 includes a first adhesive element 161 and a non-adhesive compressible element 162. The compressible element 162 is bonded to the flexible circuit board 140 through the first adhesive element 161, and the compressible element 162 is in a compressed state within the wire hole 130d.

[0095] In this embodiment, the first adhesive 161 may be, but is not limited to, double-sided adhesive. The compressible member 162 may be, but is not limited to, foam. The first adhesive 161 is adhesive, the compressible member 162 is not adhesive, and the compressible member 162 can be compressed. The compressible elastic member 160 is received in the thread hole 130d, and the compressible member 162 in the compressible elastic member 160 is in a compressed state within the thread hole 130d.

[0096] In this embodiment, the first adhesive member 161 has a first adhesive surface 1611 and a second adhesive surface 1612 facing away from each other. The compressible elastic member 160 is bonded to the first adhesive surface 1611, and the second adhesive surface 1612 is bonded to the flexible circuit board 140.

[0097] In this embodiment, the compressible elastic member 160 includes a first adhesive member 161 and a non-adhesive compressible member 162. The compressible member 162 is bonded to the flexible circuit board 140 through the first adhesive member 161. On the one hand, during the assembly of the connector 300, the compressible elastic member 160 is easily inserted into the wiring hole 130d along with the flexible circuit board 140. On the other hand, the compressible member 162 of the compressible elastic member 160 accommodates the wiring hole 130d, and the compressible member 162 of the compressible elastic member 160 is in a compressed state within the wiring hole 130d. Therefore, the compressible member 162 of the compressible elastic member 160 can hold the flexible circuit board 140 against the inner wall of the connector shell 131 that defines the wiring hole 130d, which is in close or near close contact with the inner wall. Thus, the distance between the touch module 151 of the flexible circuit board 140 and the outer surface 131b of the connecting shell 131 that defines the through hole 130d is relatively consistent. Consequently, the distance and relative position between the flexible circuit board 140 and the outer surface 131b of the connecting shell 131 are consistent, resulting in good touch sensitivity consistency of the touch module 151. Furthermore, the compressible elastic member 160 includes a first adhesive member 161 and a non-adhesive compressible member 162, demonstrating that the structure of the compressible elastic member 160 is simple and easy to implement.

[0098] Please see Figure 11 , Figure 11 For another implementation method Figure 2 The diagram shows a cross-sectional view of the earphone along line II. The connecting shell 131 is a flexible connecting shell, and the connector 300 further includes a reinforcing member 170. The reinforcing member 170 is embedded in the connecting shell 131, and the reinforcing member 170 is spaced apart from the flexible circuit board 140.

[0099] The connector 300 further includes a reinforcing member 170 that can be incorporated into the earphone 1 provided in any of the preceding embodiments. For example, the connector 300 may be incorporated into a connector 300 including a compressible elastic member 160, or into a connector 300 that does not include a compressible elastic member 160. The connector 300 in the schematic diagrams of the embodiments of this application should not be construed as a limitation on the embodiments of this application.

[0100] In this embodiment, the connecting shell 131 is a flexible connecting shell. For example, the material of the connecting shell 131 can be, but is not limited to, plastic or silicone.

[0101] The reinforcing member 170 can be, but is not limited to, a reinforcing metal sheet, such as a reinforcing steel sheet or a reinforcing copper sheet. The reinforcing member 170 can be embedded in the connecting shell 131 by means of injection molding.

[0102] The strength of the flexible connecting shell is less than the overall strength of the reinforcing member 170 and the connecting shell 131. In other words, compared to the connecting member 300 that does not include the reinforcing member 170, the connecting member 300 provided in this embodiment of the application further includes the reinforcing member 170. The reinforcing member 170 is embedded in the connecting shell 131, which can improve the structural strength and clamping force of the connecting part 130. If the connecting member 300 is applied to the earphone 1 and the earphone 1 is worn by the wearer, the earphone 1 is not easy to fall off the wearer.

[0103] In one embodiment, the initial distance between the first part 110 and the second part 120 is less than the minimum thickness of the ear. Therefore, when the earphone 1 with the connector 300 is worn on the ear, the ear will spread the first part 110 and the second part 120 apart, increasing the distance between the first part 110 and the second part 120. This increases the outward force applied to both ends of the connector 130, and the reinforcing member 170 of the connector 130 generates a restoring force that moves closer to each other. Under the action of this restoring force, the first end 1311 and the second end 1312 of the connector 130 generate a clamping force that moves closer to each other, thereby making the first part 110 and the second part 120 tighten on the opposite sides of the ear, so that the earphone 1 is not easy to fall off when worn on the ear.

[0104] The reinforcing member 170 is spaced apart from the flexible circuit board 140 to avoid interference between them, ensuring the reliability of the components or circuits on the flexible circuit board 140. When the reinforcing member 170 strengthens the connection portion 130, it also ensures the reliability of the components or circuits on the flexible circuit board 140. Specifically, if the reinforcing member 170 is not spaced apart from the flexible circuit board 140, the reinforcing member 170 will adhere to the flexible circuit board 140, potentially squeezing the components or circuits on the flexible circuit board 140 and causing it to fail.

[0105] In one embodiment, the reinforcing member 170 is a plate with shape memory function. When the earphone 1 is in a natural state, the reinforcing member 170 has a preset shape to ensure that the connecting portion 130 has a specific shape when the earphone 1 is in a natural state. Further, in one embodiment, the reinforcing plate can deform to provide clamping force when the earphone 1 is worn on a wearer.

[0106] Please continue reading. Figure 11 In one embodiment, the connecting shell 131 has an inner surface 131a and an outer surface 131b disposed opposite to each other. The reinforcing member 170 and the flexible circuit board 140 are spaced apart along the thickness direction of the connecting shell 131, and the reinforcing member 170 is adjacent to the inner surface 131a relative to the flexible circuit board 140.

[0107] The first part 110, the connecting part 130, and the second part 120 define a wearing space 1a. When the earphone 1 is worn by a wearer, the wearing space 1a is used to accommodate the wearer. The inner surface 131a of the connecting shell 131 is the surface of the connecting shell 131 that defines the wearing space, and the outer surface 131b of the connecting shell 131 is the surface of the connecting shell 131 that faces away from the wearing space 1a.

[0108] When the earphone 1 is worn by a wearer, the outer surface 131b is away from the wearer compared to the inner surface 131a. In other words, the inner surface 131a is the surface facing the wearer when the earphone 1 is worn by the wearer, and the outer surface 131b is the surface away from the wearer when the earphone 1 is worn by the wearer.

[0109] The reinforcing member 170 and the flexible circuit board 140 are spaced apart along the thickness direction of the connecting shell 131. This allows full utilization of the thickness dimension of the connecting shell 131, rather than its width dimension. Therefore, the width dimension of the connecting shell 131 is smaller, resulting in a more compact connector 300. This also makes the earphone 1, to which the connector 300 is used, more compact in appearance.

[0110] The reinforcing member 170 is adjacent to the inner surface 131a of the flexible circuit board 140. Therefore, the reinforcing member 170 causes less or no obstruction to the functional devices in the functional area 140a of the flexible circuit board 140, thereby ensuring the performance of the functional module 150 of the connector 300.

[0111] Please see Figure 12 , Figure 12 for Figure 11 Enlarged schematic diagram at point III. In one embodiment, the distance d between the reinforcing member 170 and the flexible circuit board 140 satisfies: 0.3mm ≤ d ≤ 2.0mm.

[0112] For example, the distance d between the reinforcing member 170 and the flexible circuit board 140 can be, but is not limited to, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, or 2.0mm.

[0113] If the distance between the reinforcing member 170 and the flexible circuit board 140 is too small, it will be difficult to achieve in terms of manufacturing process. For example, if the reinforcing member 170 is embedded in the connecting shell 131 by injection molding, the injection molding will be difficult if the distance between the reinforcing member 170 and the flexible circuit board 140 is too small. If the distance between the reinforcing member 170 and the flexible circuit board 140 is too large, the outer diameter of the connecting portion 130 will be large, thereby increasing the size of the connecting portion 130.

[0114] The connector 300 provided in this application embodiment has a distance d between the reinforcing member 170 and the flexible circuit board 140 satisfying: 0.3mm≤d≤2.0mm. On the one hand, this makes the process easier to implement, and on the other hand, it makes the outer diameter of the connecting part 130 smaller, making the connector 300 more compact and lightweight.

[0115] See Figure 2 , Figure 8 , Figure 13 and Figure 14 , Figure 13 This is a schematic diagram of a touch area and touch module according to an embodiment of this application; Figure 14 This is a schematic diagram of a touch area and a touch module according to another embodiment of this application. The functional area 140a includes a touch area 141a. The functional module 150 includes a touch module 151, which is located in the touch area 141a. The connecting portion 130 has a touch operation area 13a corresponding to the touch area 141a, and the length L of the touch operation area 13a in the extending direction satisfies: 6mm ≤ L ≤ 20mm.

[0116] In one embodiment, the length L of the touch operation area 13a in the extending direction can be, but is not limited to, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm.

[0117] If the size of the touch operation area 13a in the extending direction is too small, it indicates that the touch module 151 occupies a small size, which is not conducive to operating the touch module 151 in the touch area 141a (such as sliding operation); if the size of the touch operation area 13a in the extending direction is too large, it indicates that the touch module 151 occupies a large size, which is not conducive to setting other devices or modules in the connection part 130 of the earphone 1.

[0118] The connector 300 provided in this application embodiment has a touch operation area 13a whose length L in the extension direction satisfies: 6mm≤L≤20mm. On the one hand, this is beneficial for operating the touch module 151 in the touch area 141a, for example, the sliding operation is more flexible; on the other hand, the size occupied by the touch module 151 is moderate, which provides relatively sufficient space for setting other devices or modules in the connection part 130 of the connector 300.

[0119] Furthermore, in one embodiment, the length L of the touch operation area 13a in the extending direction satisfies: 10mm≤L≤15mm.

[0120] In one embodiment, the length L of the touch operation area 13a in the extending direction can be, but is not limited to, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm.

[0121] The connector 300 provided in this application embodiment has a touch operation area 13a with a length L in the extension direction satisfying: 10mm≤L≤15mm, which further accommodates the operation of the touch module 151 in the touch area 141a; and also accommodates the placement of other devices or modules in the connection portion 130 of the connector 300.

[0122] In one embodiment, if the touch module 151 detects a touch action along the first direction D1, a first function is triggered. If the touch module 151 detects a touch action along the second direction D2, a second function is triggered, wherein the second direction D2 is opposite to the first direction D1, and the first function is opposite to the second function.

[0123] Touch operations along the first direction D1 can be called sliding operations or sliding touch along the first direction D1, and dimensional operations along the second direction D2 can also be called sliding operations or sliding touch along the second direction D2.

[0124] In this embodiment, if the touch module 151 detects a touch action along the first direction D1, the first function is triggered; if the touch module 151 detects a touch action along the second direction D2, the second function is triggered; the second direction D2 is opposite to the first direction D1, and the second function is opposite to the first function; thus, it can be seen that the connector 300 provided in this embodiment facilitates control using the touch module 151, and the control method is relatively simple.

[0125] In one embodiment, the touch module 151 includes a plurality of sensors 1511 (such as sensing capacitors) arranged along a first direction D1. The plurality of sensors 1511 refers to two or more sensors 1511. For example, please refer to... Figure 13 In one embodiment, the touch module 151 includes two sensors 1511 arranged along a first direction D1, the two sensors 1511 being spaced apart. In another embodiment, please refer to... Figure 14 The touch module 151 includes three sensors 1511 arranged along the first direction D1, and the three sensors 1511 are respectively spaced apart.

[0126] In one embodiment, the touch module 151 is integrated into the flexible circuit board 140. Specifically, the circuit board body 1401 includes a conductive layer, and the touch module 151 is located on the conductive layer. The touch module 151 includes a plurality of sensors 1511, which are located on the conductive layer. During the fabrication of the flexible circuit board 140, the plurality of sensors 1511 can be fabricated in the conductive layer of the circuit board body 1401. Furthermore, during the fabrication of the flexible circuit board 140, corresponding connecting wires can also be fabricated in the conductive layer of the circuit board body 1401.

[0127] Combination Figure 2 , Figure 8 , Figure 13 and Figure 14 In this embodiment, the first direction D1 is towards the first part 110, and the first function is either decreasing the volume or increasing the volume. Correspondingly, the second direction D2 is away from the first part 110, and the second function is either decreasing the volume or increasing the volume.

[0128] Specifically, in this embodiment, the connecting portion 130 has a first end 1311 and a second end 1312. The first direction D1 is the direction toward the first end 1311, and the second direction D2 is the direction away from the first end 1311. The first function is to decrease the volume; the second function is to increase the volume. In the schematic diagram of this embodiment, the first direction D1 is the direction toward the first end 1311, and the second direction D2 is the direction away from the first end 1311. It should be understood that the schematic diagram of this embodiment should not be construed as a limitation on the embodiment of this application.

[0129] In another embodiment, the first direction D1 is toward the first end 1311, and the first function is to increase the volume; correspondingly, the second direction D2 is away from the first end 1311, and the second function is to decrease the volume.

[0130] Since the first direction D1 is towards the first end 1311 and the second direction D2 is away from the first end 1311, when the user operates the area of ​​the connecting part 130 corresponding to the area where the touch module 151 is located, the user can utilize the dimension of the extending direction of the connecting part 130. The connecting part 130 has enough space to arrange the touch module 151 and can avoid increasing the width of the connecting part 130.

[0131] In this embodiment, the first function is either decreasing the volume or increasing the volume; correspondingly, the second function is either decreasing the volume or increasing the volume. Thus, the volume can be controlled by operating the touch operation area of ​​the connecting shell 131 corresponding to the touch module 151 along the first direction D1 or along the second direction D2, and the control method is relatively simple.

[0132] Understandably, in other embodiments, the first direction D1 is the width direction of the connecting portion 130, and correspondingly, the second direction D2 is the direction opposite to the first direction D1 in the width direction of the connecting portion 130. This application does not limit the first direction D1 and the second direction D2, as long as the first direction D1 and the second direction D2 are opposite.

[0133] Understandably, in this embodiment, the first function is either decreasing the volume or increasing the volume; the second function is either decreasing the volume or increasing the volume, which is just one example. In the connector 300 provided in one embodiment of this application, decreasing the volume means decreasing the volume of the speaker, and correspondingly, increasing the volume means increasing the volume of the speaker. Understandably, in other embodiments, if the speaker 111 of the headphones 1 is playing music, the first function is either playing the next song or playing the previous song, and correspondingly, the second function is either playing the next song or playing the previous song. Understandably, in yet another embodiment, if the speaker 111 of the headphones 1 is playing audio (including music or voice, etc.), the first function may also be either playing at double speed or playing at slow speed; the second function may be either playing at double speed or playing at slow speed. The headphones 1 provided in this embodiment of the application do not limit the first and second functions.

[0134] In another embodiment, the first function includes connecting to Bluetooth and disconnecting Bluetooth, and the second function includes connecting to Bluetooth or disconnecting Bluetooth.

[0135] In other embodiments, the first function includes switching device connections and not switching device connections, and the second function includes switching device connections and not switching device connections.

[0136] Therefore, the connector 300 provided in this application embodiment allows the touch module 151 to detect a touch operation along the first direction D1 to trigger a first function and a touch operation along the second direction D2 to trigger a second function, the second function being the opposite of the first function, thereby making the control of the first function and the second function relatively simple.

[0137] In one embodiment, if the touch module 151 detects a touch operation exceeding a preset duration and is a first duration, a preset mode is activated. If the touch module 151 detects a touch operation exceeding a preset duration and is a second duration, the preset mode is deactivated.

[0138] If the touch module 151 detects that the touch operation exceeds the preset duration and is the first duration, the preset mode is activated, thereby reducing or even avoiding accidental activation of the preset mode, and thus improving the accuracy of activating the preset mode.

[0139] If the touch module 151 detects that the touch operation exceeds the preset time and is the second duration, the preset mode is turned off, thereby reducing or even avoiding accidental touches that turn off the preset mode, and thus improving the accuracy of turning off the preset mode.

[0140] Touch operations exceeding a preset duration can also be termed long-press touch. In one embodiment, the first duration and the second duration are equal. In another embodiment, the first duration and the second duration are not equal.

[0141] The preset mode may include, but is not limited to, a noise reduction mode for the speaker. For example, if the preset mode of the earphone 1 of the connector 300 is in the off state, and the touch module 151 detects that the touch operation exceeds a preset duration and is a first duration, the preset mode of the speaker 111 is turned on. If the preset mode of the earphone 1 is in the on state, and the detection mode detects that the touch operation exceeds a preset duration and is a second duration, the preset mode of the speaker 111 is turned off.

[0142] The connector 300 provided in this embodiment can enable or disable a preset mode based on the duration of the touch operation detected by the touch module 151, thereby making it relatively easy to enable or disable the preset mode.

Figure 15 , Figure 16 and Figure 17 , Figure 15 For another implementation method Figure 2 A schematic diagram of the cross-sectional structure of the earphone along line II shown; Figure 16 A schematic diagram of a flexible circuit board in an earphone according to one embodiment; Figure 17 for Figure 15 The diagram shows a circuit diagram of the antenna. In this embodiment, the functional area 140a further includes a first antenna area 141b. The first antenna area 141b is spaced apart from the touch area 141a, and the first antenna area 141b is disposed corresponding to the second sub-connection portion 130b. The functional module 150 further includes an antenna 152, at least a portion of which is located in the first antenna area 141b.

[0144] In one embodiment, the first antenna region 141b and the touch region 141a are spaced apart; and the touch region 141a is disposed corresponding to the first sub-connection portion 130a and a portion of the third sub-connection portion 130c; the first antenna region 141b is disposed corresponding to the second sub-connection portion 130b and a portion of the third sub-connection portion 130c. For example, in Figure 15 In the middle, the touch area 141a is located Figure 15 The boundary line L13 shown is located in the region adjacent to one side of the first part 110; the first antenna region 141b is located in Figure 15The boundary line L14 shown is located in the area adjacent to the second part 120. Boundary lines L13 and L14 are virtual lines, both corresponding to the third sub-connecting part 130c. Boundary line L13 is closer to the first part 110 than boundary line L14, and boundary line L14 is closer to the second part 120 than boundary line L13.

[0145] Please see Figure 17 Typically, the antenna 152 includes a radiator 1521 and a feed s0. The feed s0 is electrically connected to the radiator 1521 to excite the radiator 1521 to support a target frequency band. For example, the feed s0 is electrically connected to the radiator 1521 to support the radiator 1521 in receiving and / or transmitting electromagnetic wave signals of the target frequency band. The target frequency band can be, but is not limited to, the Bluetooth band. If the target frequency band is the Bluetooth band, the antenna 152 of the earphone 1 is a Bluetooth antenna. In one embodiment, the antenna 152 of the earphone 1 communicates with the antenna of an electronic device. In one embodiment, at least one of the radiator 1521 and the feed s0 is located in the first antenna region 141b. In one embodiment, the radiator 1521 is located in the first antenna region 141b. The earphone 1 to which the connector 300 is applied includes a first part 110 and a second part 120. The first part 110 further includes a motherboard with respect to one of the second part 120, and the feed s0 is located on the motherboard. The feed source S0 is electrically connected to the radiator 1521 via the motherboard and the flexible circuit board 140.

[0146] The functional module 150 also includes an antenna 152 that can be integrated into the connector 300 and earphone 1 provided in any of the preceding embodiments. In the schematic diagram of this embodiment, the first antenna region 141b is also included in the functional area 140a of the circuit board body 1401 in the connector 300, and the functional module 150 also includes an antenna 152 integrated into the connector 300 and earphone 1 to which the connector 300 is applied, as an example. It should be understood that this should not be construed as a limitation of the embodiments of this application.

[0147] The first antenna region 141b of the circuit board body 1401 is used to carry at least a portion of the antenna 152. Therefore, the first antenna region 141b can also be referred to as the region in the circuit board body 1401 used to set at least a portion of the antenna, or the first antenna region 141b can also be referred to as the radio frequency antenna region, or radio frequency antenna area, or RF antenna trace area, or RF antenna trace area.

[0148] In one embodiment, the touch area 141a of the circuit board body 1401 and the first antenna area 141b are spaced apart. The touch area 141a and the first antenna area 141b of the circuit board body 1401 are also spaced apart, as are the touch module 151 and the antenna 152. This reduces interference between the touch module 151 and the antenna 152 during operation.

[0149] The circuit board body 1401 has a touch area 141a and a first antenna area 141b. The touch module 151 is disposed in the touch area 141a, and the antenna 152 is disposed in the first antenna area 141b. Therefore, the circuit board body 1401 can integrate the touch area 141a where the touch module 151 is disposed and the first antenna area 141b where the antenna 152 is disposed, thus integrating multiple functions in the flexible circuit board 140. Furthermore, the flexible circuit board 140 does not require, or minimally requires, an increase in the external dimensions of the connector 300. If the connector 300 is applied to the earphone 1, there is no need to increase the space in the first part 110 or the second part 120 of the earphone 1 to accommodate the touch module 151 and the antenna 152. This facilitates the miniaturization of the first part 110 and the second part 120 of the earphone 1.

[0150] In one embodiment, the flexible circuit board 140 is used to electrically connect the first part 110 and the second part 120. For example, the flexible circuit board 140 is used to electrically connect devices in the first part 110 (such as a speaker 111) and devices in the second part 120 (such as a battery 121). Further, the circuit board body 1401 has a touch area 141a and a first antenna area 141b, the touch module 151 is disposed in the touch area 141a, and the antenna 152 is disposed in the first antenna area 141b. Thus, the flexible circuit board 140 achieves multiple functions, that is, multiple functions are integrated in the flexible circuit board 140.

[0151] The connector 300 provided in this embodiment includes an antenna 152 in the functional module 150, thus enabling the connector 300 to perform communication functions. At least a portion of the antenna 152 is located in the first antenna region 141b, and the antenna 152 corresponds to the second sub-connecting portion 130b of the connecting portion 130. Therefore, the antenna 152 can fully utilize the space of the second sub-connecting portion 130b of the connecting portion 130 of the connector 300. If the connector 300 is applied to the earphone 1, the volume of the first portion 110 and the second portion 120 of the earphone 1 is relatively small, resulting in a compact appearance for the earphone 1.

[0152] Further, as described above, the connecting portion 130 includes a first sub-connecting portion 130a, a second sub-connecting portion 130b, and a third sub-connecting portion 130c. The first sub-connecting portion 130a has a first end 1311, and the second sub-connecting portion 130b has a second end 1312; the third sub-connecting portion 130c connects the first sub-connecting portion 130a and the second sub-connecting portion 130b, and has a vertex P0 of the connecting portion 130. The first end 1311 connects to the first part 110, and the second end 1312 connects to the second part 120. The first part 110 includes a speaker 111. The functional area 140a of the circuit board body 1401 includes a touch area 141a and a first antenna area 141b. The touch module 151 is located in the touch area 141a, and at least a portion of the antenna 152 is located in the first antenna area 141b. Therefore, both the touch module 151 and the antenna 152 can make full use of the space of the connecting part 130 without occupying the space of the first part 110 and the second part 120 of the earphone 1 to which the connector 300 is applied, making the volume of the first part 110 and the second part 120 relatively small, and making the appearance of the earphone 1 to which the connector 300 is applied more compact.

[0153] Please see Figure 8 , Figure 9 , Figure 15 As shown in the accompanying drawings, in this embodiment, the compressible elastic member 160 is fixed to the side of the flexible circuit board 140 away from the touch module 151. The compressible elastic member 160 is disposed corresponding to the touch area 141a, and the compressible elastic member 160 avoids at least a portion of other areas of the flexible circuit board 140 other than the touch area 141a.

[0154] In this embodiment, the compressible elastic element 160 is provided corresponding to the touch area 141a. The compressible elastic element 160 avoids at least a portion of other areas in the flexible circuit board 140 other than the touch area 141a. Therefore, the compressible elastic element 160 is lightweight, which is beneficial to the lightweight design of the earphone 1.

[0155] For ease of description, the end of the flexible circuit board 140 adjacent to the second end 1312 of the connecting portion 130 is designated as the free end, which is located outside the touch area 141a. In one embodiment, the compressible elastic member 160 avoids the free end. This reduces the mass of the compressible elastic member 160, contributing to the lightweight design of the earphone 1. When the connector 300 is assembled, the free end of the flexible circuit board 140 can be inserted into the wiring hole 130d, causing the portion of the flexible circuit board 140 corresponding to the touch area 141a and the compressible elastic member 160 corresponding to the touch area 141a to enter the wiring hole 130d. Therefore, by avoiding the free end, the compressible elastic member 160 facilitates the assembly of the flexible circuit board 140 and the compressible elastic member 160 into the wiring hole 130d of the connecting portion 130.

[0156] Please see Figure 2 ,and Figures 15 to 17 As shown in the accompanying drawings, in this embodiment, the compressible elastic element 160 is fixed to one side of the flexible circuit board 140. The compressible elastic element 160 is disposed corresponding to the touch area 141a and also corresponds to the first antenna area 141b. The compressible elastic element 160 is in a compressed state within the wire hole 130d.

[0157] In this embodiment, the compressible elastic member 160 is fixed to one side of the flexible circuit board 140. The compressible elastic member 160 is disposed corresponding to the touch area 141a and also corresponding to the first antenna area 141b. The compressible elastic member 160 is in a compressed state within the through hole 130d. On one hand, the compressible elastic member 160 can hold the portion of the flexible circuit board 140 corresponding to the touch area 141a against the inner wall of the connecting shell 131 that defines the through hole 130d, which is in close contact with or approximately in close contact with the inner wall of the connecting shell 131. In this way, the distance and relative position between the outer surface 131b of the connecting shell 131 and the surface of the flexible circuit board 140 where the touch module 151 is disposed (also called the FPC functional surface) can be kept consistent, thereby improving the consistency of touch function sensing and reducing or eliminating situations where the touch is sensitive at times and unresponsive at others. On the other hand, the compressible elastic member 160 can also hold the portion of the flexible circuit board 140 corresponding to the first antenna region 141b against the inner wall of the connecting shell 131 that defines the through hole 130d. This reduces or even eliminates the shaking of the touch module 151 caused by the shaking of the portion of the flexible circuit board 140 corresponding to the first antenna 152 region, further improving the consistency of the distance and relative position between the outer surface 131b of the connecting shell 131 and the surface of the flexible circuit board 140 where the touch module 151 is located (also called the FPC functional surface), thereby further improving the consistency of touch function sensing.

[0158] exist Figure 8 In the corresponding embodiments, the compressible elastic member 160 is disposed corresponding to the touch area 141a of the circuit board body 1401, and the compressible elastic member 160 avoids at least a portion of other areas of the circuit board body 1401 other than the touch area 141a, for example, the compressible elastic member 160 avoids the first antenna area 141b. Figure 15 In the corresponding embodiments, the compressible elastic element 160 is disposed corresponding to the touch area 141a, and the compressible elastic element 160 is also disposed corresponding to the first antenna area 141b. Whether the compressible elastic element 160 is disposed corresponding to the first antenna area 141b can be determined according to the actual situation of the earphone 1 or the radio frequency performance of the antenna 152. This application does not limit whether the compressible elastic element 160 is disposed corresponding to the first antenna area 141b.

[0159] Please continue reading. Figure 2 , Figure 17 , Figure 18 and Figure 19 See attached images. Figure 18 For another implementation method Figure 2A schematic diagram of the cross-sectional structure of the earphone along line II shown; Figure 19 for Figure 18 A schematic diagram of the flexible circuit board and functional modules is shown. In this embodiment, the earphone 1 includes a first part 110, a second part 120, and a connector 300. The connector 300 is used to connect the first part 110 and the second part 120. Specifically, the connector 300 includes a connecting part 130 and a flexible circuit board 140. The flexible circuit board 140 is supported on the connecting part 130. The flexible circuit board 140 includes a circuit board body 1401 and a functional module 150. The circuit board body 1401 has one or more functional regions 140a, which are disposed corresponding to the connecting part 130. The functional module 150 is disposed in the functional region 140a.

[0160] In this embodiment, the connecting portion 130 has a first end 1311 and a second end 1312. The first end 1311 is connected to the first portion 110, and the second end 1312 is connected to the second portion 120. The circuit board body 1401 has a functional region 140a, which is disposed corresponding to the connecting portion 130. The functional module 150 is disposed in the functional region 140a.

[0161] In this embodiment, the first part 110 includes a speaker 111. The first end 1311 and the second end 1312 are disposed opposite to each other. The connecting part 130 has a first sub-connecting part 130a, a second sub-connecting part 130b, and a third sub-connecting part 130c. The third sub-connecting part 130c connects the first sub-connecting part 130a and the second sub-connecting part 130b. The functional area 140a includes a touch area 141a. Correspondingly, the functional module 150 includes a touch module 151. The touch module 151 is located in the touch area 141a, and the touch area 141a is disposed corresponding to at least one of the first sub-connecting part 130a or the third sub-connecting part 130c.

[0162] The first part 110, the second part 120, the connecting part 130, the touch module 151, the flexible circuit board 140, the first sub-connecting part 130a, the second sub-connecting part 130b, and the third sub-connecting part 130c are described above and will not be repeated here.

[0163] In this embodiment, the functional module 150 also includes a touch module 151, thus enabling the connector 300 to have more functions. The touch module 151 requires user operation. If the touch module 151 is located in the first part 110, and the earphone 1 is worn inside the concha of the ear, the user wearing the earphone 1 needs to operate the area of ​​the first part 110 corresponding to the touch module 151 with their hand, which may compress the ear and provide a poor user experience. In this embodiment, the functional module 150 includes the touch module 151, and the touch area 141a is provided corresponding to at least one of the first sub-connection part 130a or the third sub-connection part 130c. If the earphone 1 to which the connector 300 is applied is worn, the user wearing the earphone 1 can easily operate the touch module 151 by operating the at least one corresponding to the operation area of ​​the touch module 151. This facilitates user operation of the touch module 151.

[0164] Furthermore, in this embodiment, the first part 110 has a first housing 112. The circuit board body 1401 also has a second antenna region 141c. The second antenna region 141c is located within the first housing 112. The functional module 150 also includes an antenna 152. At least a portion of the antenna 152 is located in the second antenna region 141c.

[0165] Generally speaking, please refer to Figure 17 The antenna 152 includes a radiator 1521 and a feed s0. At least one of the radiator 1521 and the feed s0 is located in the second antenna region 141c. The feed s0 is electrically connected to the radiator 1521 to excite the radiator 1521 to support a target frequency band. For example, the feed s0 is electrically connected to the radiator 1521 to support the radiator 1521 in receiving and / or transmitting electromagnetic wave signals of the target frequency band. The target frequency band can be, but is not limited to, the Bluetooth band. If the target frequency band is the Bluetooth band, the antenna 152 of the earphone 1 is a Bluetooth antenna. In one embodiment, the antenna 152 of the earphone 1 communicates with the antenna of an electronic device. In one embodiment, at least one of the radiator 1521 and the feed s0 is located in the first antenna region 141b. In one embodiment, the radiator 1521 is located in the first antenna region 141b. The earphone 1 to which the connector 300 is applied includes a first part 110 and a second part 120. The first part 110 also includes a motherboard, one of the second parts 120, and the feed source S0 is located on the motherboard. The feed source S0 is electrically connected to the radiator 1521 through the motherboard and the flexible circuit board 140.

[0166] In this embodiment, the circuit board body 1401 further has a second antenna region 141c, which is located within the first housing 112. In other words, in this embodiment, a portion of the circuit board body 1401 is located at the connection portion 130, and a portion is located within the first housing 112. The portion of the circuit board body 1401 located within the first housing 112 has the second antenna region 141c. The antenna 152 is located within the second antenna region 141c, which is located within the first housing 112. In other words, the radiator 1521 of the antenna 152 is located within the second antenna region 141c within the first housing 112. The first housing 112 can protect the radiator 1521, thus reducing or even preventing damage to the radiator 1521.

[0167] Furthermore, in one embodiment, the hardness of the first housing 112 is greater than the hardness of the connecting portion 130. Because the first housing 112 is harder than the connecting portion 130, the first housing 112 is less prone to deformation compared to the connecting portion 130. The radiator 1521 is located within the first housing 112; therefore, the environmental consistency of the radiator 1521 is better, resulting in better communication quality when using the antenna 152.

[0168] Furthermore, the circuit board body 1401 also has a second antenna region 141c, which is located within the first housing 112; the portion of the circuit board body 1401 located within the first housing 112 is also referred to as the tail of the circuit board body 1401, and the second antenna region 141c is also referred to as the tail region of the circuit board body 1401.

[0169] In one embodiment, the portion of the circuit board body 1401 located within the first housing 112 may also be provided with a touch area 141a. However, if the first part 110 includes a speaker 111 (i.e., the first part 110 is a sound-emitting part or a sound-emitting ball), and if the portion of the circuit board body 1401 located within the first housing 112 is provided with a touch area 141a, and the touch area 141a is provided with a touch module 151; then when the earphone 1 is worn on the ear, the first part 110 (i.e., the sound-emitting ball) is located within the concha of the ear. Each time the user touches the portion of the first part 110 corresponding to the touch module 151 to achieve the touch function, the first part 110 will be squeezed, thereby squeezing the ear, resulting in a relatively poor user experience. Therefore, in this embodiment, the circuit board body 1401 also has a second antenna area 141c, where the radiator 1521 of the antenna 152 (also called a radio frequency antenna) is provided. Here, the function module 150 that performs a certain function does not require touching to operate.

[0170] For further information, please refer to [link / reference]. Figure 18 In one embodiment, the earphone 1 further includes a second adhesive member 180. The second adhesive member 180 bonds the portion of the circuit board body 1401 located in the first housing 112 to the first housing 112.

[0171] The second adhesive 180 can be, but is not limited to, double-sided adhesive. The second adhesive 180 bonds the flexible circuit board 140 to the portion of the first housing 112 located thereon, thereby preventing the flexible circuit board 140 from shifting and causing a deterioration in the environmental consistency of the antenna 152. Therefore, by bonding the flexible circuit board 140 to the portion of the first housing 112 located thereon, the second adhesive 180 further improves the environmental consistency of the antenna 152, resulting in better communication quality when using the antenna 152.

[0172] Further, in one embodiment, the first part 110 includes a speaker 111 and a first housing 112. The first housing 112 has a first receiving cavity 112a and a sound outlet 112b. The first receiving cavity 112a is used to receive the speaker 111, and the sound outlet 112b communicates with the first receiving cavity 112a. The second part 120 includes a battery 121 and a second housing 122. The second housing 122 has a second receiving cavity 122a. The second receiving cavity 122a is used to receive the battery 121. The battery 121 is electrically connected to the speaker 111 through the flexible circuit board 140 to supply power to the speaker 111.

[0173] In this embodiment, the speaker 111 is also referred to as a loudspeaker. The sound outlet 112b connects to the first receiving cavity 112a. In one embodiment, the sound outlet 112b connects the first receiving cavity 112a and the outer surface of the first housing 112 to transmit the sound emitted by the speaker 111 to the outside. If the earphone 1 is worn on a person's ear, the sound outlet 112b transmits the sound emitted by the speaker 111 to the person's ear.

[0174] The battery 121 can be, but is not limited to, a rechargeable battery or a disposable battery. The battery 121 can be electrically connected to the speaker 111 in a manner that is not limited to, the battery 121 being electrically connected to the speaker 111 via wiring on the flexible circuit board 140.

[0175] The earphone 1 provided in this application embodiment has a speaker 111 housed in a first receiving cavity 112a of the first housing 112 and a battery 121 housed in a second receiving cavity 122a of the second housing 122. This design allows the first part 110 to be smaller in size, making it easier to wear on a wearer (such as a human ear). Furthermore, it allows for a relatively balanced size and weight between the first part 110 and the second part 120, resulting in a better appearance and wearing experience for the earphone 1.

[0176] In one embodiment, the second part 120 further includes a main board 125. The main board 125 is located within the second receiving cavity 122a. The main board 125 is also electrically connected to the flexible circuit board 140. The main board 125 is electrically connected via the flexible circuit board 140 to a speaker 111 located within the first receiving cavity 112a of the first housing 112.

[0177] Understandably, in other embodiments, the first part 110 has a mainboard 125. The mainboard 125 is located within the first receiving cavity 112a. The mainboard 125 is electrically connected to the flexible circuit board 140. This application embodiment does not limit whether the mainboard 125 is located within the first receiving cavity 112a or the second receiving cavity 122a.

[0178] Further, please refer to Figure 18 and Figure 20 , Figure 20 This is a circuit block diagram of an earphone according to one embodiment of the present application. In one embodiment, the earphone 1 further includes a speaker 111, a vibration sensor 190, and a control chip 113. The speaker 111 is housed in either the first housing 112 or the second housing 122. In the schematic diagram of this embodiment, the speaker 111 is housed in the first housing 112 as an example, and it should not be construed as a limitation on the earphone 1 provided in this embodiment. The vibration sensor 190 is housed in either the first housing 112 or the second housing 122. The vibration sensor 190 is used to detect a tapping action. In one embodiment, the control chip 113 is located on the motherboard 125, but it is not limited thereto. The control chip 113 is electrically connected to the vibration sensor 190 and to the speaker 111. The control chip 113 controls the speaker 111 to perform corresponding functions according to the tapping action. In the schematic diagram of this embodiment, the vibration sensor 190 is housed in the second housing 122 as an example. It should be understood that this should not be construed as a limitation on the embodiment of this application.

[0179] The vibration sensor 190 is also referred to as a vibration detection sensor or a vibration sensor. In one embodiment, the vibration sensor 190 includes multiple gravity sensors (G sensors), but is not limited to this.

[0180] The vibration sensor 190 is housed in either the first housing 112 or the second housing 122, that is, the vibration sensor 190 is housed in either the first housing 112 or the second housing 122.

[0181] In one embodiment, the vibration sensor 190 is located on the motherboard 125. If the motherboard 125 is located in the first receiving cavity 112a of the first housing 112, then the vibration sensor 190 is located in the first receiving cavity 112a of the first housing 112; if the motherboard 125 is located in the second receiving cavity 122a of the second housing 122, then the vibration sensor 190 is located in the second receiving cavity 122a of the second housing 122.

[0182] The vibration sensor 190 can detect tapping motions at any position on the earphone 1. Therefore, the earphone 1 is also referred to as having a full-area tapping detection function.

[0183] The control chip 113 is electrically connected to the vibration sensor 190, which can be achieved, but is not limited to, through the lines or connecting wires of the flexible circuit board 140. The control chip 113 is also electrically connected to the speaker 111, which can be achieved, but is not limited to, through the lines or connecting wires of the flexible circuit board 140.

[0184] The control chip 113 controls the speaker 111 to perform corresponding functions based on the tapping action. For example, the control chip 113 controls the speaker 111 to perform different functions based on the number of taps detected by the vibration sensor 190. For instance, if the vibration sensor 190 detects the first number of taps, the control chip 113 controls the speaker 111 to perform a first function based on the first number of taps; if the vibration sensor 190 detects the second number of taps, the control chip 113 controls the speaker 111 to perform a second function based on the second number of taps.

[0185] In one embodiment, the first number of times is a positive integer greater than or equal to 2; the second number of times is a positive integer greater than or equal to 2; thus, the probability of the vibration sensor 190 being accidentally touched can be reduced.

[0186] Further, please refer to Figure 18The first part 110 includes a first housing 112, and the second part 120 includes a second housing 122. The hardness of the first housing 112 is greater than the hardness of the connecting part 130, and the hardness of the second housing 122 is greater than the hardness of the connecting part 130. The earphone 1 also includes a first connector 210 and a second connector 220. The first connector 210 is connected to the first end 1311 of the connecting part 130, and the hardness of the first connector 210 is greater than the hardness of the connecting part 130. The first end 1311 of the connecting part 130 is connected to the first housing 112 through the first connector 210. The second connector 220 is connected to the second end 1312 of the connecting part 130, and the hardness of the second connector 220 is greater than the hardness of the connecting part 130. The second end 1312 of the connecting part 130 is connected to the second housing 122 through the second connector 220.

[0187] In this embodiment, the hardness of the first housing 112 is greater than the hardness of the connecting portion 130. If the connecting portion 130 is directly connected to the first housing 112, the connection between the connecting portion 130 and the first housing 112 is unstable. Correspondingly, the hardness of the second housing 122 is greater than the hardness of the connecting portion 130. If the connecting portion 130 is directly connected to the second housing 122, the connection between the connecting portion 130 and the second housing 122 is also unstable.

[0188] The earphone 1 provided in this embodiment further includes a first connector 210 connected to a first end 1311. The hardness of the first connector 210 is greater than that of the connecting portion 130. The first end 1311 of the connecting portion 130 is connected to the first housing 112 via the first connector 210. Therefore, the connection between the first end 1311 of the connecting portion 130 and the first housing 112 is relatively strong.

[0189] Accordingly, the earphone 1 also includes a second connector 220, which is connected to the second end 1312. The hardness of the second connector 220 is greater than that of the connecting portion 130. The second end 1312 of the connecting portion 130 is connected to the second housing 122 through the second connector 220. Therefore, the connection between the second end 1312 of the connecting portion 130 and the second housing 122 is relatively firm.

[0190] In summary, the earphone 1 provided in one embodiment of this application includes a first part 110, a second part 120, and a connector 300. The connector 300 includes a flexible circuit board 140, which includes a circuit board body 1401. The circuit board body 1401 has a functional area 140a, which is disposed corresponding to the connector 130 of the earphone 1. In one embodiment, the functional module 150 includes at least one of a touch module 151 and an antenna 152. If the functional module 150 includes a touch module 151, the touch module 151 is disposed corresponding to the connector 130 of the earphone 1. Therefore, the earphone 1 provided in this embodiment places the touch function in the connector 130, which is more easily touched by the user, thereby facilitating the operation of the earphone 1 by the user when it is worn.

[0191] Further, in one embodiment, the first part 110 includes a speaker 111; therefore, the first part 110 is also referred to as a sound-emitting bulb. The connecting part 130 has a first sub-connecting part 130a, a second sub-connecting part 130b, and a third sub-connecting part 130c. The third sub-connecting part 130c is located between the first connecting part 130 and the second sub-connecting part 130b. The touch area 141a is provided corresponding to at least one of the first sub-connecting part 130a and the third sub-connecting part 130c. Therefore, the touch area 141a can also be described as being provided corresponding to the transition area of ​​the connecting part 130 (also referred to as the connecting bridge) adjacent to the first part 110 (i.e., the sound-emitting bulb).

[0192] During the assembly of the earphone 1, a touch area 141a (also known as a touch-sensing area) needs to be pre-designed on the circuit board body 1401, and a touch module 151 is set in the touch area 141a. Then, the flexible circuit board 140 is inserted into the wiring hole 130d of the connecting bridge. After the wiring of the flexible circuit board 140 is completed, the touch-sensing part of the flexible circuit board 140 is located within the pre-designed touch area 141a.

[0193] The main advantage of the earphone 1 provided in one embodiment of this application is that multiple functions are integrated onto the flexible circuit board 140 located on the connecting part 130 (also called the connecting bridge) of the connector 300. The flexible circuit board 140 no longer simply serves to connect the first part 110 and the second part 120. If one of the first part 110 and the second part 120 is a sound tube, and the other of the first part 110 and the second part 120 is a battery, then the flexible circuit board 140 no longer only serves to connect the sound tube and the battery, but can also have touch control function and / or antenna 152 function. It can be seen that, in the earphone 1 provided in this embodiment of the application, if the touch module 151 and the antenna 152 are both disposed on the circuit board body 1401, then the earphone 1 does not need to have a separate antenna independent of the flexible circuit board 140, nor does it need to have a separate touch module 151 (also called a touch function module) independent of the flexible circuit board 140, thus saving this part of the cost. Furthermore, if the touch module 151 and the antenna 152 are both disposed on the circuit board body 1401 and located in the connection portion 130, it is also referred to as the touch module 151 and the antenna 152 being integrated into the connection bridge; therefore, there is no need to increase the space of at least one of the battery bead and the sound outlet ball to accommodate the touch module 151 and the antenna 152, and therefore, the appearance of the earphone 1 is more compact.

[0194] In one embodiment, the earphone 1 further includes a vibration sensor 190, which is capable of detecting tapping motions at any location on the earphone 1. Therefore, the earphone 1 is also referred to as having a full-area tapping detection function.

[0195] Furthermore, the earphone 1 also includes a functional module 150, which includes a touch module 151. Therefore, the earphone 1 provided in this embodiment is also referred to as the earphone 1 retaining the basic operation of tapping the entire area, while adding a touch module 151 to achieve touch functionality. The touch module 151 can implement swipe touch and / or long-press touch. Swipe touch implemented by the touch module 151 may include, but is not limited to, touch operations along a first direction D1 (also called swiping along the first direction D1), and / or touch operations along a second direction D2 (also called swiping along the second direction D2). Long-press touch may include, but is not limited to, touch operations exceeding a preset duration and being a first duration, and / or touch operations exceeding a preset duration and being a second duration.

[0196] In one embodiment, the functional module 150 includes a touch module 151, which is disposed in the functional area 140a of the circuit board body 1401, and the functional area 140a corresponds to the connection part 130. When the earphone 1 is worn on the ear, the connection part 130 is located in a place that is easily accessible by hand, making it convenient for the user to operate.

[0197] Further, in one embodiment, the first part 110 includes a speaker 111, the functional area 140a includes a touch area 141a, and the functional module 150 includes a touch module 151. The touch module 151 is located in the touch area 141a, and the touch area 141a is provided corresponding to at least one of the first sub-connection part 130a and the third sub-connection part 130c. When the earphone 1 is worn in the ear, the first part 110 is located in the concha of the ear. The first sub-connection part 130a is easier to find by blind touch than the second sub-connection part 130b, and the third sub-connection part 130c is easier to find by blind touch than the second sub-connection part 130b. The touch area 141a is provided for at least one of the first sub-connection portion 130a and the third sub-connection portion 130c. The earphone 1 is worn on the ear. When the user wearing the earphone 1 operates the touch module 151, there is no need to put their hand deep into the back of the ear to touch it, thereby improving the convenience of operation.

[0198] For example, in one embodiment, the first part 110 includes a speaker 111, also referred to as a sound-emitting bulb; the connecting part 130 is also referred to as a connecting bridge. The first sub-connecting part 130a of the connecting part 130 is also referred to as the transition region from the sound-emitting bulb to the connecting bridge, and the third sub-connecting part 130c is also referred to as the intermediate region of the connecting bridge. The touch area 141a is provided corresponding to at least one of the first sub-connecting part 130a and the third sub-connecting part 130c; therefore, the touch area 141a is also referred to as corresponding to at least one of the transition region from the sound-emitting bulb of the earphone 1 to the connecting bridge and the intermediate region of the connecting bridge. For example, the touch area 141a corresponds to the transition region from the sound-emitting bulb of the earphone 1 to the connecting bridge, or the touch area 141a corresponds to the intermediate region of the connecting bridge of the earphone 1, or the touch area 141a corresponds to the transition region of the earphone 1 and the intermediate region of the connecting bridge.

[0199] Further, in one embodiment, the second part 120 includes a battery 121, also referred to as a battery bead; the connecting part 130 is also referred to as a connecting bridge. The second sub-part is also referred to as the transition region from the battery bead to the connecting bridge. In one embodiment, the functional region 140a further includes a first antenna region 141b, which is disposed corresponding to the second sub-connecting part 130b. Therefore, the transition region from the battery bead to the connecting bridge is also referred to as the first antenna region 141b.

[0200] The earphone 1 provided in this application embodiment, if the touch area 141a corresponds to the first sub-connecting part 130a and the first antenna area 141b corresponds to the second sub-connecting part 130b; can also be referred to as the touch area 141a and the first antenna area 141b being distributed in the front and rear sections of the connecting bridge (also referred to as the front and rear sections of the connecting bridge). Further, in one embodiment, the connecting bridge may also have only a single functional area 140a corresponding to the touch area 141a or the first antenna area 141b, thus allowing the coverage size of the single functional area 140a to be larger.
