earphone

Abstract

The earphone provided in the application can be stably held between the antitragus and the antihelix by setting the cross-sectional shape of the second part of the main body as a triangle, so that the second part can be matched with the structure of the concha cavity. The bottom edge part of the second part corresponding to the triangle is in contact with the antitragus, and the top corner part of the second part corresponding to the triangle is in contact with the antihelix. Thus, the wearing stability of the earphone is not affected by the wearing habit or the size and structure of the ear, and the earphone will not shake or even fall off in the ear during wearing.

Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a pair of headphones. Background Technology

[0002] Headphones are energy converters that use speakers placed close to the ear canal to convert sound into audible sound waves. They are an essential accessory for portable electronic devices such as mobile phones, portable music players, and radios. In particular, Bluetooth headphones, such as True Wireless Stereo (TWS) headphones, have become a must-have item for people, especially young people, due to their advantages such as portability and avoiding tangled cables.

[0003] Generally, headphones include earbuds (also known as ear tips). When worn, at least a portion of the earbud is housed within the concha. For example, in in-ear headphones, the sound outlet portion of the earbud extends into the ear canal, while the rest of the earbud, excluding the sound outlet, is housed within the concha. The earbud is secured to the ear by the inner walls of the concha and the ear canal, thus achieving the wearing of the headphones.

[0004] However, in related technologies, the earcups of headphones are circular in structure. When worn in the ear, the circular earcups are prone to movement or even falling out due to differences in the size and structure of the human ear and wearing habits, which affects the stability of the headphones. Summary of the Invention

[0005] This application provides an earphone that can solve the problem in related technologies where earphones are prone to movement or even falling off during wear.

[0006] This application provides an earphone, including an earcup. The earcup includes a main body and a sound outlet arranged sequentially along the direction of sound propagation within the earphone. The sound outlet is used to be close to or located in the ear canal when the earphone is worn on the user's ear. At least a portion of the main body is used to be located in the concha cavity of the ear when the earphone is worn on the user's ear.

[0007] The main body has a second part and a first part arranged sequentially along the direction of sound propagation. The first part is connected to the sound output part. The cross-sectional shape of the second part perpendicular to the direction of sound propagation is configured as a triangle. The side of the second part corresponding to the base of the triangle is used to contact the tragus, and the side of the second part corresponding to the apex of the triangle is used to contact the antitragus.

[0008] The earphone provided in this application embodiment has a triangular cross-sectional shape for the second part of the main body. This triangular structure allows the second part to fit into the concha cavity structure. The base of the triangle in the second part contacts the tragus, and the apex of the triangle in the second part contacts the antitragus, thus stably holding the main body of the earphone between the tragus and antitragus. Additionally, the two sides of the triangle in the second part can also contact the inner wall of the concha cavity. In other words, the second part of the main body combines the triangular structural features with the ear structure, ensuring the earphone is stably worn in the ear. This avoids the impact of wearing habits or differences in ear size and structure on the stability of the earphone, ensuring that the earphone will not shake or fall out during wear. For example, the earphone will not move or fall out while eating or exercising, thereby improving the earphone's portability. In addition, because triangles are stable, by setting the cross-sectional shape of the second part of the main body to a triangle, the structural stability of the second part is improved, so that the structure of the second part will not be damaged when subjected to external pressure such as the tragus or the tragus squeezing the second part.

[0009] In one feasible implementation, at least a portion of the second part facing the tragus is configured as a first arcuate surface that matches the tragus. This increases the contact area between the main body and the tragus, thereby further improving the support stability of the tragus on the main body and making the main body more stable between the tragus and the antitragus. On the other hand, by setting at least a portion of the second part facing the tragus as a first arcuate surface, the fit between the main body and the tragus is higher. Compared to setting the surface of the main body facing the tragus as a flat structure, this avoids the surface of the main body and the tragus having sharp edges or other structures, thereby avoiding excessive pressure from the main body on the tragus and improving the comfort of the headphones in this embodiment during wear.

[0010] In one feasible implementation, the outer contour size of the second part is larger than that of the first part. On the one hand, this ensures that the second part is stably clamped between the tragus and the antitragus, and also allows the surface of the second part facing the sound output part to contact the inner wall of the concha cavity, further increasing the contact area between the second part and the inner wall of the concha cavity, thereby improving the wearing stability of the headphones. On the other hand, the smaller outer contour size of the first part also makes it easier to wear in the transition area between the concha cavity and the ear canal.

[0011] In one feasible implementation, the outer surfaces corresponding to the three corners of the second part are configured as second arc-shaped surfaces, which match the inner wall of the concha cavity to improve the fit between the three corners of the second part and the inner wall of the concha cavity. This avoids the parts of the outer surfaces corresponding to the three corners of the second part that come into contact with the inner wall of the concha cavity having sharp edges or other structures, thereby preventing the second part from causing excessive pressure on the inner wall of the concha cavity and improving the wearing comfort of the earmuff.

[0012] In one feasible implementation, the earpiece includes a housing and an antenna assembly located within the housing;

[0013] The housing includes a main housing, a cover plate, and an annular pickup mesh. The cover plate is located at the end of the main housing away from the sound outlet, and the cover plate is connected to the main housing through the annular pickup mesh. The main housing, the cover plate, and the annular pickup mesh together form the inner cavity of the earpiece.

[0014] The antenna assembly includes an antenna radiator, and a ring-shaped pickup grid is configured as the antenna radiator.

[0015] This embodiment of the application increases the pickup area for external noise by setting a ring-shaped pickup mesh at one end of the main housing away from the sound outlet, i.e., a ring of pickup mesh is set around one end of the main housing in a circumferential direction. This allows the front reference microphone inside the earcup to effectively acquire external environmental noise, thereby enhancing the headphone's pickup effect and improving its noise reduction performance. Furthermore, this embodiment of the application uses the ring-shaped pickup mesh directly as the antenna radiator in the antenna assembly. On the one hand, it enables signal reception for electronic devices such as mobile phones; on the other hand, it makes reasonable use of the ring-shaped pickup mesh. In other words, the antenna radiator and the ring-shaped pickup mesh are conformal, meaning one device performs two functions, saving overall earcup space. This reduces the headphone's size and provides suitable installation space for other components inside the earcup, also reducing the headphone's manufacturing cost.

[0016] In one feasible implementation, the earpiece also includes a support member located within the inner cavity of the annular pickup grille, with an annular gap formed between the outer wall of the support member and the inner wall of the annular pickup grille, and at least a portion of the cover plate is supported on the support member.

[0017] The antenna assembly is a slot antenna, the support is configured as the reference ground of the slot antenna, and the annular gap is configured as the slot of the slot antenna.

[0018] The earphones provided in this application embodiment use a support member for supporting the cover plate as the reference ground for the antenna assembly, and the annular gap between the support member and the ring-shaped pickup mesh as the slot of the antenna assembly. On the one hand, this makes the antenna assembly a slot antenna. For example, after the ring-shaped pickup mesh, which is the antenna radiator, is fed with a current signal, it can radiate electromagnetic waves through the slot. Alternatively, the antenna assembly can act as a receiving antenna, receiving electromagnetic wave signals through the slot and converting them into current signals, which are then fed to the receiving end on the circuit board via the antenna radiator. On the other hand, the antenna assembly makes reasonable use of the existing components inside the earcup, namely the support member. In other words, the support member is conformal to the reference ground, meaning that one device performs two functions, thereby saving the overall space of the earcup and reducing the number of earphone components. This facilitates the assembly of the earphones and reduces the size of the earcup, saving on the manufacturing cost. In addition, by setting the antenna assembly as a slot antenna, the height of the antenna assembly is reduced, thereby reducing the space occupied by the antenna assembly inside the earcup, making the earcup more compact and easier to wear and store. In addition, slot antennas have a larger physical aperture and better radiation performance compared to monopoles. Furthermore, combined with the ring structure of the ring pickup mesh itself, the ring slot is easy to form, thus simplifying the manufacturing process of the antenna assembly.

[0019] In one feasible implementation, the earpiece also includes a support located within the earpiece cavity; the support includes a fixing portion and at least one extension portion, the fixing portion being fixed to the inner wall of the housing, one end of the extension portion being connected to the fixing portion, and the other end of the extension portion being connected to a support member, so as to stably support the support member within the annular pickup grille.

[0020] In one feasible implementation, the earpiece also includes a circuit board located within the housing, on the side of the support facing away from the cover plate, and the annular pickup grille has multiple spaced connections.

[0021] Multiple connectors are connected to the circuit board, wherein at least one connector is configured as a feed point for the antenna assembly, and another connector is configured as a ground point for the antenna assembly.

[0022] This application embodiment improves the connection stability between the ring-shaped microphone mesh and the circuit board by setting multiple connecting parts on the ring-shaped microphone mesh. Furthermore, by using at least one connecting part as a power supply point and another as a grounding point, and connecting them to the circuit board respectively, it facilitates the electrical connection between the power supply point of the antenna radiator and the RF signal port on the circuit board, and also grounds the antenna radiator. On the other hand, it makes efficient use of the connecting parts on the ring-shaped microphone mesh; in other words, the connecting parts serve two functions, thereby saving overall earphone space, reducing the number of headphone components, facilitating headphone assembly, reducing the size of the headphone earphone, and saving headphone manufacturing costs.

[0023] In one feasible implementation, the feed point is positioned away from the auricle when the earpiece is worn inside the ear, in order to reduce the absorption of radio frequency signals by the human body. On the one hand, the radio frequency signal can enter the antenna radiator to a greater extent and radiate electromagnetic waves through the gap, ensuring the radiation performance of the antenna assembly. On the other hand, it reduces the radiation caused by the radio frequency signal to the human body, ensuring human health.

[0024] In one feasible implementation, the headphone's support frame is located between the circuit board and the support member. The circuit board is fixed to the side of the support frame facing away from the support member to stabilize the circuit board. The support frame has clearance holes, and the components on the circuit board pass through these clearance holes. This prevents the components on the circuit board from being damaged by interference from the support frame and also saves space occupied by the assembly structure of the support frame and circuit board inside the earcup. Furthermore, this allows components such as capacitive sensors to accurately detect touch positions on the cover plate. Additionally, the support frame has a through hole corresponding to the connecting part, through which the connecting part passes and connects to the circuit board.

[0025] In one feasible implementation, the circuit board inside the headphones has multiple pre-reference microphones spaced apart. Compared to a single pre-reference microphone, this allows the headphones to pick up more ambient sound reference information, resulting in higher ambient sound reference value from multiple pre-reference microphones. This leads to better noise reduction performance in the headphones and also improves the user's transparency experience and sense of space.

[0026] In one feasible implementation, the spacing between two adjacent front reference microphones is greater than or equal to 15mm.

[0027] By setting the spacing between two adjacent front reference microphones within the range mentioned above, it is ensured that the areas of ambient sound picked up by each front reference microphone do not overlap, further ensuring that the ambient sound picked up by multiple front reference microphones is more meaningful for reference.

[0028] In one feasible implementation, the cross-sectional shape of the circuit board is configured as a triangle;

[0029] There are three preamplifier microphones, which are set at the three corners of the circuit board to make reasonable use of the circuit board structure and maximize the spacing between adjacent preamplifier microphones.

[0030] In one feasible implementation, the cover of the earcup is a capacitor panel, which is positioned away from the sound outlet and has multiple touch buttons.

[0031] Among them, at least two touch buttons are spaced apart along a first direction, and at least two touch buttons are spaced apart along a second direction, with an angle between the first direction and the second direction.

[0032] This embodiment of the application sets the ear cup cover as a capacitive panel, and sets multiple touch buttons spaced apart along a first direction and a second direction on the capacitive panel. This allows for the design of various gestures, such as long touch, short touch, sliding along the first direction, and sliding along the second direction, to control different functions, thereby improving the user interaction experience and enriching human-computer interaction methods and application scenarios. Furthermore, because the capacitive panel is positioned away from the inner wall of the concha, compared to buttons on both sides of the ear shaft in related technologies, the interference from the ear is weaker when the user operates the touch buttons in this embodiment, thus improving the convenience of interaction.

[0033] In one feasible implementation, the cross-sectional shape of the capacitor panel is triangular;

[0034] The capacitive panel has three touch buttons spaced apart along a first direction, and the capacitive panel has three touch buttons spaced apart along a second direction.

[0035] The first direction is perpendicular to the base of the triangle, and the first direction is perpendicular to the second direction.

[0036] This application embodiment makes reasonable use of the structure of a triangular capacitive panel. Three touch buttons are arranged along a first direction perpendicular to the bottom edge, and three touch buttons are arranged along a second direction. For example, three touch buttons are arranged at intervals along a direction perpendicular to the bottom edge. In addition, a touch button is arranged on each of the two sides of the triangle. This enables multiple human-computer interaction methods, thereby improving the user interaction experience and making it easier for the user to operate.

[0037] In one feasible implementation, a roller is provided on the side of the main body facing the tragus, and one end face of the roller is used to abut against the tragus.

[0038] The scroll wheel can rotate along its own axis to switch the functions of the headphones.

[0039] In this embodiment, a roller is provided on one side of the main body to enable switching of headphone functions, i.e., to realize human-computer interaction. On the other hand, the end face of the roller abuts against the tragus to ensure the stability of the main body inside the ear.

[0040] In one feasible implementation, the roller can move along its own axis to configure the roller as a button;

[0041] A portion of the end face protrudes from the cover plate of the main body.

[0042] This application embodiment enriches the human-computer interaction method and expands the usage scenarios of the headphones by setting the scroll wheel as a button that can move along its own axis, thereby realizing the multi-functional switching of the headphones. In addition, by making the end face of the scroll wheel protrude from the cover plate of the main body, it is convenient to press the scroll wheel. Attached Figure Description

[0069] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0070] This application provides an earphone, which can be a wired earphone or a wireless earphone, such as a Bluetooth earphone. The Bluetooth earphone can be a True Wireless Stereo (TWS) earphone.

[0071] Bluetooth earphones, such as TWS earphones, have experienced explosive growth in a short period. More and more people are getting used to using TWS earphones in the office, while traveling, and at the gym. TWS earphones have also become an essential item for young people, who have developed a personal habit of using them without hesitation. Compared to traditional wired earphones, TWS earphones have the advantages of being easy to carry and avoiding tangled cables.

[0072] This application uses TWS earphones as an example for specific embodiments.

[0073] Figure 1 This is a structural diagram of an earphone in related technologies. Figure 2 This is a diagram illustrating the structure of an ear. Figure 3 This is a schematic diagram of the structure of headphones worn on a user's ear in related technologies. (Refer to...) Figure 1 As shown, in the related technology, the earphone 10a includes an ear cup 11a and an ear stem 12a, wherein one end of the ear cup 11a is provided with a sound outlet 14a, wherein, Figure 1 The middle earpiece 13a is fitted onto the sound outlet 14a, which is used to transmit the sound emitted by the speaker inside the earpiece 11a to the user's ear canal 23 (see reference). Figure 2 As shown), the other end of the earpiece 11a is connected to the ear stem 12a. Generally, the ear stem 12a has function keys such as touch buttons to switch functions on the earphone 10a. In related technologies, the cross-sectional shape of the earpiece 11a perpendicular to the direction of sound propagation is circular. The direction of sound propagation is referenced... Figure 1 As indicated by the middle arrow a. It can be understood that the direction of sound propagation a refers to the extension direction of the sound transmission path within the earpiece 11a from the sound outlet surface of the speaker to the sound outlet 14a.

[0074] It is understood that in related technologies, the earphone 10a can be an in-ear earphone or a semi-in-ear earphone. In some embodiments, the earphone 10a may further include an ear tip 13a, which, along with the sound outlet 14a, enters the user's concha 26 (see reference). Figure 3 As shown in the figure, in some embodiments it can even enter the user's ear canal 23, which has a noise isolation effect and makes the user experience better.

[0075] Reference Figure 1 and Figure 3As shown, for example, taking an in-ear headphone as an example, the sound outlet 14a of the headphone 10a may have an ear tip 13a (or ear cover). When the sound outlet 14a and the ear tip 13a are inserted into the ear canal 23, the ear tip 13a has a good seal against the ear canal 23, thus having a good noise isolation effect and making the user experience better.

[0076] For example, the earphone 10a is a semi-in-ear earphone. The ear tip 13a may not be provided on the sound outlet 14a of the earphone 10a. The ear cup 11a of the earphone 10a and the sound outlet 14a on the ear cup 11a are located in the concha cavity 26.

[0077] In practical applications, due to differences in human genes, ears also exhibit variations. For example, the size and type of ears may differ between different users, and even the left and right ears of the same user may differ. (Referring to...) Figure 2 As shown, this can be specifically reflected in the following ways: the concha 26 of some ears 20 is too large, the concha 26 of some ears 20 is too small, the antitragus 22 of some users' ears 20 is protruding, and the antitragus 22 of some users' ears 20 is flat.

[0078] Reference Figure 2 and Figure 3 As shown, taking in-ear headphones as an example, when the headphones 10a are worn, the circular earpiece 11a is inserted into the concha cavity 26. Due to the differences in the size and type of the ears 20, the fit of the earpiece 11a in the concha cavity 26 is poor. For example, when the ears 20 are too large, or the concha cavity 26 is too large, the earpiece 11a cannot fit against the inner wall of the concha cavity 26. When the user is eating or walking, the earpiece 11a is very easy to shake or even fall off in the concha cavity 26.

[0079] For example, if the ear 20 is too small, such as if the concha 26 is too small, the ear sac 11a cannot be completely inserted into the concha 26, which may cause the ear sac 11a to fall out of the concha 26 when the user is active. Alternatively, if the antitragus 22 of the user's ear 20 is flat, the antitragus 22 cannot effectively prevent the ear sac 11a from falling out, resulting in poor stability of the ear sac 11a within the concha 26.

[0080] It should be noted that the inner wall of the concha cavity 26 includes the inner floor wall and the side walls of the concha cavity 26. The inner floor wall refers to the inner wall of the concha cavity 26 facing the external environment, and the side walls surround the inner floor wall. The side walls include the side wall of the tragus 21 facing the antitragus 22 and the side wall of the antitragus 22 facing the tragus 21.

[0081] In practical applications, users have different habits when wearing headphones 10a. For example, some users are used to wearing them forward, that is, close to the ear canal 23, while others are used to wearing them backward, that is, close to the antitragus 22. This will affect the wearing angle of the ear cup 11a in the concha 26, which will affect the stability of the ear cup 11a in the concha 26. For example, when the user wears headphones 10a backward, the ear cup 11a of headphones 10a cannot fit stably with the antitragus 21, which makes the ear cup 11a very easy to shake or even fall off in the concha 26 when the user is active.

[0082] When in use, the poor fit of the earcup 11a within the concha 26 makes it easy for music to pause or switch when the user is active, such as while eating, as the earcup 11a moves within the concha 26. In addition, the music cannot be paused when the earcup 11a falls off abnormally, which affects the user's wearing experience.

[0083] Based on this, this application provides an earphone that makes reasonable use of the structure of the ear. For example, the earpiece is stably fixed in the ear by the tragus and antitragus, avoiding the impact of wearing habits or differences in ear size and structure on the stability of the earphone. This ensures that the earphone will not shake or fall out in the ear during wearing, such as when eating or exercising, thereby improving the portability of the earphone.

[0084] The structure of the earphone in the embodiment of this application will be described in detail below.

[0085] Example 1

[0086] Figure 4 This is a structural schematic diagram of the headphones provided in one embodiment of this application from one viewpoint. Figure 5 This is a schematic diagram of the structure of an earphone worn on a user's ear according to an embodiment of this application. Figure 6 This is a schematic diagram of the structure of an earphone provided in one embodiment of this application, with the cover plate and pickup mesh removed.

[0087] Reference Figures 4 to 6 As shown, this application embodiment provides an earphone 10, which includes an earcup, the earcup including a section along the sound propagation direction within the earphone 10 (refer to...). Figure 4 The main body 11 and the sound-emitting part 12 are arranged sequentially in the direction indicated by the middle arrow b. The sound-emitting part 12 is used to be close to or located in the ear canal 23 of the ear 20 when the earphone is worn on the user's ear 20. At least a part of the main body 11 is used to be located in the concha 26 of the ear 20 when the earphone is worn on the user's ear 20.

[0088] Reference Figure 4As shown, in practical applications, the sound output section 12 includes a sound output housing 122 and a sound output nozzle 121 formed at the end of the sound output housing 122. In practical applications, a damping mesh (not shown in the figure) can be provided on the sound output nozzle 121 to adjust the air compliance inside the earpiece, thereby improving the sound quality of the headphones 10. In addition, the damping mesh also serves to block external dust and other debris, extending the service life of the headphones 10.

[0089] Reference Figure 4 As shown, the main body 11 includes a main housing 113 and components located within the main housing 113. These components include a circuit board 17 (mentioned below), a speaker, a battery, etc. The battery provides power to the electrical components inside the earpiece to ensure their normal operation. The circuit board 17 integrates a capacitive sensor 171, a charging circuit, etc., and also serves as a connection carrier for various logically related components. The speaker converts electrical signals into sound signals; this speaker can be a microelectromechanical speaker, a moving-coil speaker, or a balanced-iron speaker, etc.

[0090] Here, the main body shell 113 refers to the annular shell arranged around the sound propagation path of the main body 11. In other words, the main body shell 113 does not include the cover plate 133 and the annular pickup mesh 132 (which will be mentioned below, see reference) of the main body 11 away from the sound outlet 12. Figure 7 (As shown).

[0091] In practical applications, the earphone 10 has at least one speaker inside. Taking a single speaker as an example, this speaker (e.g., a first speaker) divides the inner cavity of the earphone into a front cavity and a rear cavity, wherein the front cavity is close to the sound outlet 12, and the rear cavity faces away from the sound outlet 12. For example, the sound outlet surface of the first speaker and part of the main body shell 113 form the front cavity, and the back surface of the first speaker (facing away from the sound outlet surface) and part of the main body shell 113 form the rear cavity. The sound outlet surface of the first speaker can face the sound outlet 121, for transmitting the sound emitted by the diaphragm of the first speaker to the ear canal 23 of the ear 20 through the sound outlet 121.

[0092] In this embodiment, the direction of sound propagation within the earphone 10 (refer to...) Figure 4 The direction indicated by the middle arrow (b) refers to the extended direction of the propagation path emanating from the diaphragm of the first loudspeaker and propagating to the sound outlet 121.

[0093] The earphone 10 in this embodiment can be a semi-in-ear earphone. For a semi-in-ear earphone, the outer contour dimensions of the sound-emitting part 12 and the main body 11 can be the same, or the outer contour dimension of the sound-emitting part 12 can be larger than the outer contour dimension of the main body 11. Of course, in other examples, the outer contour dimension of the sound-emitting part 12 can decrease along the direction of sound propagation. Here, the outer contour dimension of the sound-emitting part 12 or the main body 11 refers to the cross-sectional dimension of the sound-emitting part 12 or the main body 11 perpendicular to the direction of sound propagation, i.e., the b-direction.

[0094] When wearing semi-in-ear headphones, the sound output part 12 and at least part of the main body part 11 are located in the concha cavity 26, and the sound output nozzle of the sound output part 12 faces the ear canal 23. The sound output surface of the speaker emits sound and transmits it into the ear canal 23 through the sound output nozzle 121 of the sound output part 12, so that the user can receive the sound emitted by the headphones 10 well.

[0095] Reference Figure 4 As shown, the earphone 10 in this embodiment can also be an in-ear earphone. For in-ear earphones, an ear tip (not shown in the figure) can be fitted onto the sound output part 12, referring to... Figure 5 As shown, when wearing in-ear headphones, the sound output part 12 and the ear tip extend into the ear canal 23, and at least a portion of the main body 11 is located within the concha 26. Because the ear tip can effectively seal the ear canal 23, it has excellent sound insulation, resulting in a superior user experience.

[0096] The following explanation uses in-ear headphones as an example.

[0097] Reference Figure 4 As shown, in the earphone 10 of this embodiment, the outer contour dimension of the sound-emitting part 12 is smaller than the outer contour dimension of the main body 11, so that when the earphone 10 is worn in the ear 20, a portion of the sound-emitting part 12 can extend into the ear canal 23, so that the sound-emitting shell (or the ear cover on the sound-emitting part 12) seals the ear canal 23, thereby isolating external noise and improving the user experience. For example, refer to Figure 6 As shown, the main body 11 includes a second part 112 and a first part 111 arranged sequentially along the direction of sound propagation. The first part 111 is connected to the sound output part 12. When arranged, the outer contour dimensions of the first part 111 and the second part 112 can be larger than the outer contour dimensions of the sound output part 12.

[0098] Reference Figure 4 As shown, the main body 11 includes a first side (see reference) disposed opposite to the direction of sound propagation (i.e., direction b). Figure 4 (as shown in A) and the second side (refer to) Figure 4 (As shown in Figure B). Refer to... Figure 4As shown, when the earphone 10 is worn in the user's ear 20, one side of the main body 11, such as the first side A, is used to abut against the tragus 21 of the ear 20, and the other side of the main body 11, such as the second side B, is used to abut against the antitragus 22 of the ear 20, so as to clamp the main body 11 between the tragus 21 and the antitragus 22.

[0099] It should be noted that, in this embodiment, the two sides of the main body 11 directly abut against the inner wall of the ear 20. For example, the first side A of the main body 11 can directly abut against the tragus 21, and the second side B of the main body 11 can directly abut against the antitragus 22. Specifically, the first side A of the main body 11 abuts against the inner surface of the tragus 21 facing the concha 26, and the second side B of the main body 11 specifically abuts against the inner surface of the antitragus 22 facing the concha 26.

[0100] Reference Figure 2 As shown, the inner wall of the concha 26 of the ear 20 includes an inner bottom wall 263 facing the opening of the concha 26 and an inner side wall connected to the inner bottom wall 263. It can be understood that the inner surface of the tragus 21 facing the concha 26 is part of the inner side wall of the concha 26, and correspondingly, the inner surface of the tragus 22 facing the concha 26 is another part of the inner side wall of the concha 26.

[0101] For ease of description, the inner surface of the tragus 21 facing the concha cavity 26 is referred to as the inner surface of the tragus 261, and the inner surface of the antitragus 22 facing the concha cavity 26 is referred to as the inner surface of the antitragus 262. The inner wall of the concha cavity 26 can be composed of the inner bottom wall 263, the inner surface of the tragus 261, the inner surface of the antitragus 262, and the remaining part of the inner sidewall.

[0102] Reference Figure 4 and Figure 5 As shown in the embodiment of this application, the sidewalls of the main body 11 are in contact with the tragus 21 and the antitragus 22. For example, the surface of the first side A of the main body shell 113 of the main body 11 is in contact with the tragus 21, and the surface of the second side B of the main body shell 113 is in contact with the antitragus 22.

[0103] Reference Figure 4 As shown, because the tragus 21 and antitragus 22 are small in size, when the earphone 10 is worn in the user's ear 20, a portion of the surface of the first side A of the main body 11 abuts against the tragus 21, and a portion of the surface of the second side B of the main body 11 abuts against the antitragus 22.

[0104] Reference Figure 5As shown, by way of example, when the earphone 10 is worn in the user's ear 20, the first side A of the second part 112 of the main body 11 can abut against the tragus 21, and the second side B of the second part 112 of the main body 11 can abut against the antitragus 22, so as to stably clamp the main body 11 in the concha cavity 26 between the tragus 21 and the antitragus 22.

[0105] The earphone 10 provided in this application embodiment, by having one side of the main body 11 of the earbud abut against the tragus 21 of the ear 20 and the other side of the main body 11 abut against the antitragus 22 of the ear 20, can stably hold the main body 11 of the earbud between the tragus 21 and the antitragus 22 when the earbud is worn in the user's ear 20. In other words, this application embodiment makes reasonable use of the structure of the ear 20, and uses the tragus 21 and the antitragus 22 to stably fix the earbud in the ear 20, avoiding the impact of wearing habits or different sizes and structures of the ear 20 on the wearing stability of the earphone 10, and ensuring that the earphone 10 will not shake or fall out in the ear 20 during wearing. For example, the earphone 10 will not move or fall out during eating or exercising, thereby improving the wearing portability of the earphone 10.

[0106] Generally, the surface of the tragus 21 facing the concha 26 is an arcuate surface that bulges into the concha 26. (See reference...) Figure 5 As shown, in order to improve the structural fit between the main body 11 and the tragus 21, at least a portion of the surface of the main body 11 facing the tragus 21 is configured as a first arcuate surface that matches the tragus 21. For example, at least a portion of the surface of the first side A of the second part 112 is configured as a first arcuate surface that matches the tragus 21.

[0107] In this way, on the one hand, the contact area between the main body 11 and the tragus 21 is increased, thereby further improving the support stability of the tragus 21 on the main body 11, making the main body 11 more stable between the tragus 21 and the antitragus 22. On the other hand, data from a large number of wearing experiments show that by setting at least a portion of the surface of the main body 11 facing the tragus 21 as a first arc-shaped surface, the fit between the main body 11 and the tragus 21 is higher. Compared with setting the surface of the main body 11 facing the tragus 21 as a planar structure, the surface of the main body 11 and the tragus 21 that mates with the tragus 21 is prevented from having sharp edges or other structures, thereby avoiding excessive pressure from the main body 11 on the tragus 22 and improving the comfort of the earphone 10 in this embodiment during wearing.

[0108] In some examples, the entire surface of the first arcuate surface is an arcuate surface that curves in the same direction, for example, towards the inner cavity of the earphone 10 (see reference). Figure 4 and Figure 5 As shown), to match the inner surface of the tragus 21 (refer to...). Figure 2The inner surface of the tragus 261) is an ear that protrudes into the concha cavity 26.

[0109] In some examples, to accommodate the shape of the inner surface of the tragus 21, the first arcuate surface can also be a curved surface that bends in different directions (not shown in the figure). For example, for users whose inner surface of the tragus 22 is partly protruding towards the concha 26 and partly recessed towards the ear canal 23, the first arcuate surface of the earphone 10 can be set as a first arcuate surface a that is partly recessed into the earphone 10 and a first arcuate surface b that is partly protruding outward from the earphone 10. The first arcuate surface a contacts the part of the inner surface of the tragus 21 that protrudes into the concha 26, and the first arcuate surface b contacts the part of the inner surface of the tragus 21 that is recessed into the ear canal 23, so as to improve the fit between the first arcuate surface of the sidewall of the main body 11 and the inner surface of the tragus 21.

[0110] In the earphone 10 of this application embodiment, the specific structure of the first arc-shaped surface of the first side A of the main body 11 can be adjusted according to the structure of the actual user's ear.

[0111] Reference Figure 6 As shown, in a specific configuration, the outer contour dimension of the second part 112 is larger than that of the first part 111. For example, the cross-sectional dimension of the second part 112 perpendicular to the sound propagation direction is larger than that of the first part 111. This allows the second part 112 to be stably held between the tragus 21 and the antitragus 22 when the earphone 10 is worn in the ear 20. It also allows the surface of the second part 112 facing the sound output part 12 to engage (i.e., abut) with the inner wall of the concha 26, thereby increasing the fit between the main body 11 and the inner wall of the concha 26 and improving the wearing stability of the earpiece in the ear 20. In addition, the smaller outer contour dimension of the first part 111 also facilitates wearing in the transition area between the concha 26 and the ear canal 23.

[0112] The second part 112 has a triangular cross-sectional shape perpendicular to the direction of sound propagation; in other words, the cross-sectional shape of the main body shell 113 corresponding to the second part 112 is triangular. The side of the base of the triangle (corresponding to the first side A of the main body 11) of the second part 112 is used to abut against the tragus 21, and the side of the apex of the triangle (corresponding to the second side B of the main body 11) of the second part 112 is used to abut against the antitragus 22, wherein the apex and the base are arranged opposite each other.

[0113] For ease of understanding, the second part 112 can be regarded as a structure formed by stacking multiple triangular planes along the thickness direction (i.e., the direction of sound propagation). Then, the side of the base of the second part 112 (i.e. the surface of the first side) is formed by stacking the bases of each triangular plane.

[0114] Similarly, the side surface of the second part 112 corresponding to the apex of the triangle (i.e., the surface of the second side) is formed by stacking the apex of each triangular plane. In addition, the side surfaces of the two base angles of the second part 112 corresponding to the triangle are formed by stacking the two base angles of each triangular plane, and the side surfaces of the two base angles of the second part 112 corresponding to the triangle can abut against part of the inner wall of the concha cavity 26.

[0115] In addition, the two sides of the triangle corresponding to the second part 112 are formed by stacking the sides of each triangular plane, and the two sides of the triangle corresponding to the second part 112 can also abut against other inner walls of the concha cavity 26.

[0116] It should be noted that the two sides of a triangle refer to the two sides that are connected to the two ends of the base, and the two base angles refer to the angles between the base and the two sides.

[0117] It can be understood that the second part 112, corresponding to the side surface A of the base of the triangle, the second part 112, corresponding to the side surface B of the vertex of the triangle, the second part 112, corresponding to the side surface C of the two base angles of the triangle, and the second part 112, corresponding to the side surface D of the two lateral sides of the triangle, together form the annular side surface M of the second part 112.

[0118] In specific settings, the triangle can be an isosceles triangle, an equilateral triangle, or any triangle that matches the inner wall of the concha 26.

[0119] In this embodiment, the cross-sectional shape of the second part 112 of the main body 11 is set as a triangle. The triangular structure of the second part 112 can fit into the structure of the concha cavity 26. For example, the base of the triangle of the second part 112 can abut against the tragus 21, and the apex of the triangle of the second part 112 can abut against the antitragus 22. In addition, the two sides of the triangle of the second part 112 can abut against the inner wall of the concha cavity 26. That is, the second part 112 of the main body 11 makes reasonable use of the structural features of the triangle, further improving the wearing stability of the earpiece inside the ear 20.

[0120] In addition, because triangles are stable, by setting the cross-sectional shape of the second part 112 of the main body 11 to a triangle, the structural stability of the second part 112 is improved, so that the structure of the second part 112 will not be damaged when subjected to external pressure, such as the tragus 21 or the antitragus 22 squeezing the second part 112.

[0121] The outer surfaces corresponding to the three corners of the second part 112 (including side B corresponding to the apex corner and side C corresponding to the two bottom corners) are configured as third arc-shaped surfaces. The third arc-shaped surfaces match the inner wall of the concha 26 to improve the fit between the three corners of the second part 112 and the inner wall of the concha 26. This avoids the outer surfaces corresponding to the three corners of the second part 112 having sharp edges or other structures that come into contact with the inner wall of the concha 26, thereby preventing the second part 112 from causing excessive pressure on the inner wall of the concha 26 and improving the wearing comfort of the earmuff.

[0122] In this embodiment, the second part 112 includes a first surface (i.e., an upper surface) and a second surface (lower surface) disposed opposite to each other along the direction of sound propagation, and an annular side surface located between the first surface and the second surface. When the earphone 10 is worn, one surface A of the annular side surface abuts against the tragus 21, and the other surface B of the annular side surface abuts against the antitragus 22. When the earphone 10 is worn inside the ear 20, the first surface faces away from the inner wall of the concha 26, i.e., towards the external environment, and the second surface faces the sound outlet 12 and abuts against the inner wall of the concha 26.

[0123] It is understandable that, since the first part 111 of the main body 11 is connected to the side of the second part 112 facing the sound output part 12, the second surface is an annular surface surrounding the end of the first part 111 facing away from the sound output part 12.

[0124] In practical applications, the inner bottom wall 263 of the concha cavity 26 is an inwardly concave arc surface. In order to improve the fit between the outer wall of the earphone 10 and the inner bottom wall 263 of the concha cavity 26, the side surface (i.e., the annular surface) of the second part 112 facing the sound output part 12 is configured as a third arc surface, which matches the inner bottom wall of the concha cavity 26.

[0125] In this embodiment, the surface of the second part 112 that mates with the inner bottom wall of the concha 26 is set as a third arc-shaped surface to improve the fit between the second part 112 and the inner bottom wall of the concha 26. On the one hand, this improves the wearing stability of the earpiece within the concha 26. On the other hand, compared to setting the surface of the second part 112 facing the sound outlet as a square or similar structure, this avoids the part of the second part 112 that contacts the inner wall of the concha 26 having sharp edges or similar structures, thereby preventing the second part 112 from causing excessive pressure on the inner bottom wall of the concha 26 and improving the wearing comfort of the earpiece.

[0126] Figure 7 This is a schematic diagram of the structure of the earphone provided in one embodiment of this application from another perspective. Figure 8 yes Figure 7 Exploded view. (Refer to...) Figure 7As shown, the earcup of this embodiment includes a housing 13 and components (such as the circuit board 17 and speaker mentioned above) located within the housing 13. The housing 13 includes a main housing 131, an annular pickup grille 132, and a cover plate 133. The cover plate 133 is located at the end of the main housing 131 opposite to the sound outlet 12, and is connected to the main housing 131 via the annular pickup grille 132. The main housing 131, the cover plate 133, and the annular pickup grille 132 together form the earcup cavity 131a of the housing 13 (see reference). Figure 8 (As shown).

[0127] Reference Figure 8 As shown, the main housing 131 is understood to be a cylindrical shell arranged around the sound propagation path. For example, the main housing 131 includes a sound-emitting outer shell 122 and a main body outer shell 113. The outer contour dimensions of the main housing 131 in the direction of sound propagation (refer to...) Figure 8 As indicated by arrow b), there are differences, for example, the outer contour dimension of the sound outlet shell 122 portion of the main shell 131 may be smaller than the outer contour dimension of the main shell 113 portion.

[0128] In addition, the outer contour dimension of the first part 111 in the main body shell 113 is smaller than the outer contour dimension of the second part 112.

[0129] Reference Figure 4 As shown, in a specific configuration, the main body shell 113 in the main housing 131 may include a first housing 1131 and a second housing 1132. One end of the first housing 1131 is connected to the sound outlet housing 122, and the other end of the first housing 1131 is connected to the second housing 1132. The main body shell 113 of the first part 111 in the main body 11 includes the first housing 1131 and a portion of the second housing 1132. The main body shell 113 of the second part 112 in the main body 11 is formed by the portion of the second housing 1131.

[0130] It is understandable that when the earphone 10 is worn inside the ear 20, one side of part of the second shell 1132 is used to abut against the tragus 21, and the other side of part of the second shell 1132 is used to abut against the antitragus 22.

[0131] In practical applications, the front cavity of the earbud also contains a speaker, such as a second speaker (not shown). The sound outlet housing 122 can be a mounting bracket for the second speaker. The end of the first housing 1131 facing away from the second housing 1132 has a mounting hole. A part of the mounting bracket passes through the mounting hole and is located outside the first housing 1131, so that a part of the mounting bracket serves as the sound outlet housing 122 and forms the earbud housing 13 with the main housing 113.

[0132] In this embodiment of the application, the first shell 1131 and the second shell 1132 of the main body shell 113 can be integrally formed as a single piece. Of course, in some examples, the first shell 1131 and the second shell 1132 can be detachably connected as separate parts. For example, the first shell 1131 can be connected to one end of the second shell 1132 by means of a snap-fit ​​or the like.

[0133] Reference Figure 7 and Figure 8 As shown, one end of the annular pickup mesh 132 is connected to the end of the second housing 1132 away from the first housing 1131, and the other end of the annular pickup mesh 132 is connected to the outer edge of the cover plate 133. That is to say, the second housing 1132 of the main housing 131 and the cover plate 133 are connected by the annular pickup mesh 132.

[0134] In this embodiment of the application, a front-facing reference microphone 18 (Feedforward Reference Microphone, abbreviated as FF Mic) is provided in the ear cup cavity 131a of the housing 13 (refer to...). Figure 6 (As shown). Typically, the front reference microphone 18 is located in the rear cavity of the earpiece, and it is used to pick up ambient noise outside the earpiece and noise inside the ear canal 23.

[0135] During active noise cancellation, the ring-shaped pickup mesh 132 picks up external ambient noise and propagates it quickly to the front reference microphone 18. Noise in the ear canal 23 is propagated to the front reference microphone 18 through the front cavity of the earpiece and the speaker. The front reference microphone receives the combined noise and then uses the filter in the housing 13 to fit the noise, converting the phase of the noise to the opposite phase. The noise then enters the ear canal 23 through the speaker (e.g., the first speaker and the second speaker) to cancel out the positive phase noise directly received in the ear canal 23, thus achieving a noise reduction effect.

[0136] Figure 9 yes Figure 8 A schematic diagram of the circuit board. (Refer to...) Figure 8 and Figure 9 As shown, a circuit board 17 is typically provided in the rear cavity of the earphone. For example, the circuit board 17 can be provided inside the second housing 1132 of the earphone. The circuit board 17 is disposed opposite to the cover plate 133, and the front reference microphone 18 is disposed on the circuit board 17.

[0137] In this embodiment, the circuit board 17 may have multiple pre-reference microphones 18 spaced apart. Compared to a single pre-reference microphone 18, the headphones 10 pick up more ambient sound reference information, thus making the ambient sound reference value obtained by multiple pre-reference microphones 18 higher, resulting in better noise reduction effect of the headphones 10, and also improving the user's transparency experience and sense of space.

[0138] In specific settings, the spacing between two adjacent front reference microphones 18 (refer to...) Figure 9 The area (h shown in the figure) can be greater than or equal to 15mm to ensure that the area of ​​ambient sound picked up by each front reference microphone 18 does not overlap, and further ensure that the ambient sound picked up by multiple front reference microphones 18 is more meaningful.

[0139] It should be noted that the numerical values ​​and ranges involved in the embodiments of this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0140] For example, the spacing between two adjacent front reference microphones 18 can be a suitable value such as 15mm, 17mm, 20mm, or 25mm. It is understood that the maximum spacing between two adjacent front reference microphones 18 is determined by the size of the circuit board 17, which is located within the rear cavity of the earpiece, such as the second part 112 of the main body 11. The size of the circuit board 17 is determined by the cross-sectional dimensions of the second part 112. Therefore, in actual installation, the spacing between two adjacent front reference microphones 18 can be maximized while ensuring that the second part 112 of the earpiece can be stably inserted into the concha cavity 26.

[0141] Reference Figure 8 and Figure 9 As shown above, the cross-sectional shape of the main housing 113 corresponding to the second part 112 along the direction perpendicular to the sound propagation is triangular. For example, a portion of the cross-sectional shape of the second housing 1132 is triangular, and the cross-sectional shape of the cover plate 133 covering one end of the second housing 1132 can also be triangular. In order to match the spatial shape inside the second housing 1132, the cross-sectional shape of the circuit board 17 located inside the second housing 1132 can be configured as triangular.

[0142] Reference Figure 9 As shown, exemplarily, the number of preamplifier microphones 18 can be three. The three preamplifier microphones 18 are respectively arranged at the three corners of the circuit board 17, so as to make reasonable arrangement of the placement positions of the preamplifier microphones 18 by utilizing the structure of the circuit board 17, and to ensure that the spacing between two adjacent preamplifier microphones 18 is maximized. Of course, this application embodiment does not exclude examples of setting more than three preamplifier microphones 18 on the circuit board 17.

[0143] In this embodiment, an annular pickup mesh 132 is provided at one end of the main housing 131 away from the sound output part 12, that is, a ring of pickup mesh is provided around one end of the main housing 131 in the circumferential direction, so as to increase the pickup area of ​​the earphone 10 to pick up external noise, so that the front reference microphone 18 inside the ear canal can effectively obtain the noise of the external environment, thereby enhancing the pickup effect of the earphone 10 and improving the noise reduction effect of the earphone 10.

[0144] Reference Figure 8 As shown, when the earphone 10 in this embodiment is a Bluetooth earphone 10, such as a TWS earphone, the earcup also includes an antenna assembly 14 located within the housing 13. The control signal within the earcup is fed back to an electronic device, such as a mobile phone, through the antenna assembly 14. For example, the signal for switching music can be fed back to the earphone 10 via electromagnetic waves through the antenna assembly 14, or the sound signal sent by the electronic device, such as a mobile phone, can be received through the antenna assembly 14, processed by the speaker within the earcup, and finally transmitted into the ear canal 23.

[0145] Figure 10 yes Figure 8 Exploded view of the central ring microphone grille and circuit board. (Refer to...) Figure 8 and Figure 10 As shown, specifically, the antenna assembly 14 includes an antenna radiator 141 for receiving or transmitting signals. For example, the feed point 132a on the antenna radiator 141 can be electrically connected to the radio frequency signal port via a feed line. Exemplarily, when the antenna assembly 14 is a transmitting antenna, the radio frequency signal port is a radio frequency signal transmitter. The radio frequency signal transmitter feeds the radio frequency signal into the antenna radiator 141 via the feed line. The antenna radiator 141 transmits the radio frequency signal as electromagnetic waves to the receiving antenna of an electronic device, such as a mobile phone, thereby enabling signal interaction between the headset 10 and the electronic device.

[0146] When the antenna assembly 14 is a receiving antenna, the radio frequency signal port is a radio frequency signal receiving port. The transmitting antenna of an electronic device, such as a mobile phone, transmits a signal, such as a pause sound signal, to the earpiece in the form of electromagnetic waves, and is received by the antenna radiator 141 of the antenna assembly 14. The antenna radiator 141 then feeds the signal into the radio frequency signal receiving port through the feed point 132a and the feed line. The controller in the earpiece controls the speaker to turn off according to the signal, thereby pausing the sound in the earphone 10.

[0147] In specific settings, the ring-shaped pickup network 132 can be configured as an antenna radiator 141. In other words, the ring-shaped pickup network 132 can be directly used as an antenna radiator 141.

[0148] In this embodiment, the ring-shaped microphone mesh 132 is directly used as the antenna radiator 141 in the antenna assembly 14. On the one hand, it can realize the signal reception function of electronic devices such as mobile phones. On the other hand, it makes reasonable use of the ring-shaped microphone mesh 132. In other words, the antenna radiator 141 and the ring-shaped microphone mesh 132 are conformal, that is, one device realizes two functions, saving the overall space of the earphone. This can reduce the size of the earphone 10 and provide suitable installation space for other components in the earphone. In addition, it also reduces the manufacturing cost of the earphone 10.

[0149] In some examples, the radio frequency (RF) signal port can be located on the circuit board 17. That is, the feed point 132a of the antenna radiator 141 can be electrically connected to the circuit board 17 and connected to the RF signal port on the circuit board 17. In addition, the antenna ground point 132b can also be electrically connected to the circuit board 17.

[0150] Reference Figure 10 As shown, in a specific configuration, the ring-shaped microphone mesh 132 has multiple spaced-apart connection portions 1321, which are connected to the circuit board 17 to improve the connection stability between the ring-shaped microphone mesh 132 and the circuit board 17. At least one connection portion 1321 is configured as a feed point 132a of the antenna assembly 14, and another connection portion 1321 is configured as a ground point 132b of the antenna assembly 14.

[0151] It is understood that multiple connecting parts 1321 are spaced apart circumferentially along the ring-shaped pickup mesh 132, that is, multiple connecting parts 1321 are spaced apart around the axis of the ring-shaped pickup mesh 132. Each connecting part 1321 can be connected to the pad 172 of the circuit board 17 by soldering to ensure that the power supply point 132a and the ground point 132b are electrically connected to the circuit board 17.

[0152] Of course, in other examples, each connector 1321 can also be bonded to the circuit board 17 with conductive adhesive.

[0153] In this embodiment, the shape of the annular pickup net 132 can be triangular to match the structure of the second housing 1132.

[0154] Reference Figure 10As shown, taking the triangular ring-shaped microphone mesh 132 as an example, the connecting part 1321 can be two or more in specific configuration. For example, the number of connecting parts 1321 is two, and the two connecting parts 1321 can be respectively set on two sides of the ring-shaped microphone mesh 132. One connecting part 1321 serves as a feed point 132a, and the other connecting part 1321 serves as a ground point 132b. As another example, the number of connecting parts 1321 can be three. The three connecting parts 1321 are respectively soldered to the three sides of the circuit board 17. The first connecting part 1321 can serve as a feed point 132a, the second connecting part 1321 can serve as a ground point 132b, and the third connecting part 1321 can serve as a spare feed point 132a. In case the first connecting part 1321 fails, the third connecting part 1321 can be used as the feed point 132a to achieve electrical connection between the ring-shaped microphone mesh 132, which serves as the antenna radiator 141, and the circuit board 17.

[0155] By using at least one of the connecting parts 1321 as a feed point 132a and the other connecting part 1321 as a ground point 132b, and connecting them to the circuit board 17 respectively, on the one hand, it is convenient for the feed point 132a of the antenna radiator 141 to be electrically connected to the radio frequency signal port on the circuit board 17, and on the other hand, it makes good use of the connecting part 1321 on the ring pickup net 132. In other words, the connecting part 1321 performs two functions, thereby saving the overall space of the earcup and reducing the number of parts of the headphone 10, thus facilitating the assembly of the headphone 10, reducing the size of the earcup of the headphone 10, and saving the manufacturing cost of the headphone 10.

[0156] Furthermore, the feed point 132a and ground point 132b can be flexibly selected from multiple connection points 1321 to adjust their positions, thereby controlling the antenna impedance and radiation pattern to achieve optimal performance. For example, when the position of the feed point 132a is fixed, the position of the ground point 132b can be adjusted to make the length of the actual antenna radiator 141 of the antenna assembly 14 calibrated to 1 / 4 of the radiation wavelength, thus adjusting the antenna impedance to a suitable value and simultaneously optimizing the radiation pattern of the antenna assembly 14, thereby ensuring the radiation performance of the antenna assembly 14.

[0157] Reference Figure 2 As shown, in the ear 20, the helix 251 of the auricle 25 has an inwardly rolled structure, that is, a portion of the helix 251 is rolled towards the concha cavity 26, so that the helix 251 forms a blocking surface facing the concha cavity 26 and perpendicular to the inner bottom wall 263 of the concha cavity 26. (Refer to...) Figure 5As shown, when selecting the feed point 132a, it can be positioned away from the auricle 251 of the earlobe 25 when the earpiece is worn inside the ear 20. This reduces the obstruction and absorption of the radio frequency signal emitted by the feed point 132a by the auricle 251, thereby reducing the absorption of radio frequency signals by the human body. For example, the feed point 132a can be positioned near the earlobe 252 (see reference). Figure 5 As shown, on the one hand, radio frequency signals can enter the antenna radiator 141 to a greater extent and radiate electromagnetic waves through the gap, ensuring the radiation performance of the antenna assembly 14. On the other hand, it reduces the radiation caused by radio frequency signals to the human body and ensures human health.

[0158] Figure 11 This is a schematic diagram of the headphone structure with the cover removed according to an embodiment of this application. Figure 12 yes Figure 7 Partial sectional view. (Refer to...) Figures 9 to 12 As shown in the embodiment of this application, the earphone also includes a support member 15, which is located in the inner cavity of the annular pickup mesh 132 (see reference). Figure 11 and Figure 12 As shown), and there is a certain distance between the outer wall of the support member 15 and the inner wall of the annular pickup mesh 132, that is, an annular gap is formed between the outer wall of the support member 15 and the inner wall of the annular pickup mesh 132 (see reference). Figure 11 and Figure 12 (as shown in d).

[0159] At least a portion of the cover plate 133 is supported on the support member 15. For example, a portion of the inner surface of the cover plate 133 is supported on the support member 15 to improve the stability of the cover plate 133 at one end of the main housing 131, thereby ensuring that the cover plate 133 will not collapse when touched, pressed, slid, or otherwise moved on the cover plate 133.

[0160] In this embodiment, the support member 15 can be used as the reference ground 142 of the antenna assembly 14. For example, the antenna assembly 14 can be a slot antenna, and the annular gap d between the outer wall of the support member 15 and the inner wall of the annular pickup mesh 132 is configured as the slot of the slot antenna. For example, when the annular pickup mesh 132 is connected to the circuit board 17 through multiple connecting parts 1321, an annular gap d is formed between the inner wall of the annular pickup mesh 132 and the outer wall of the support member 15, and this annular gap can be used as the slot of the slot antenna.

[0161] When antenna assembly 14 is used as a transmitting antenna, the loop pickup mesh 132, which serves as the antenna radiator 141, converts the fed current signal into an electromagnetic wave and radiates it through the gap to transmit the signal to the signal receiver of an electronic device, such as a mobile phone. When antenna assembly 14 is used as a receiving antenna, the gap receives the electromagnetic wave signal transmitted by the electronic device and converts it into a current signal, which is then fed into the receiver on the circuit board 17 through the feed point 132a of the antenna radiator 141 for signal processing.

[0162] The antenna assembly 14 makes reasonable use of the existing components in the earpiece, namely the support 15. In other words, the support 15 is conformal with the reference ground 142, that is, one device realizes two functions, thereby saving the overall space of the earpiece and reducing the number of parts of the headphone 10, which facilitates the assembly of the headphone 10, reduces the size of the earpiece of the headphone 10, and saves the manufacturing cost of the headphone 10.

[0163] Furthermore, by setting the antenna assembly 14 as a slot antenna, the height of the antenna assembly 14 is reduced, thereby reducing the space occupied by the antenna assembly 14 inside the earpiece, making the earpiece more compact and easier to wear and store. In addition, the gap formed between the ring-shaped pickup mesh 132 and the functional module is a ring-shaped gap, which serves as the ring-shaped slot of the antenna assembly 14. Compared with a monopole, it has a larger physical aperture and better radiation performance. In addition, combined with the ring structure of the ring-shaped pickup mesh 132 itself, this ring-shaped slot is also easy to form, thereby simplifying the manufacturing process of the antenna assembly 14.

[0164] Reference Figure 8 and Figure 12 As shown, in order to support the support member 15, the inner cavity 131a of the earphone also has a bracket 16. The bracket 16 is located between the circuit board 17 and the support member 15. The bracket 16 is fixed to the inner wall of the housing 13, and the support member 15 is fixed to the bracket 16 to stably support the support member 15 within the annular pickup mesh 132.

[0165] For example, refer to Figure 12 As shown, exemplarily, the bracket 16 includes a fixing part 161 and an extension part 162. The fixing part 161 is fixed to the inner wall of the housing 13, and the circuit board 17 is fixed to the fixing part 161. One end of the extension part 162 is connected to the fixing part 161, and the other end of the extension part 162 is connected to the support member 15 to support the support member 15.

[0166] The bracket 16 has a clearance hole 161a, which is formed on the fixing part 161 to avoid obstructing components such as the capacitive sensor 171 mounted on the circuit board 17. Thus, when the circuit board 17 is fixed to the bracket 16, the capacitive sensor 171 and other components pass through the clearance hole 161a, ensuring that the bracket 16 does not cause pressure damage to the components on the circuit board 17. This also saves space occupied by the assembly structure of the bracket 16 and the circuit board 17 within the earcup cavity 131a. Furthermore, it ensures that the capacitive sensor 171 can sense the capacitance value on the cover plate 133.

[0167] It is understood that the fixing part 161 has a through hole at the position corresponding to the connecting part 1321 on the annular pickup mesh 132, so that the connecting part 1321 passes through the through hole and is connected to the connection position, such as the solder pad 172, on the circuit board 17.

[0168] Figure 13 yes Figure 4 A structural schematic diagram of the middle cover plate. (Refer to...) Figure 13 As shown in the embodiment of this application, the cover plate 133 of the ear cup can be a capacitor panel, which is disposed facing away from the sound output part 12. In this way, when the earphone 10 is worn in the ear 20, the capacitor panel is disposed facing away from the inner bottom wall 263 of the concha cavity 26, that is, the capacitor panel faces the external environment and will not be interfered with by the auricle 25.

[0169] Among them, reference Figure 13 As shown, the cover plate 133, i.e. the capacitive panel, is provided with a plurality of touch buttons 1331, wherein at least two touch buttons 1331 are spaced apart along a first direction, and at least two touch buttons 1331 are spaced apart along a second direction, and there is an angle between the first direction and the second direction.

[0170] It is understandable that the first direction and the second direction can be any direction on the cover plate 133, as long as there is an angle between the first direction and the second direction and the angle is not 0°. That is to say, it is sufficient to ensure that the first direction and the second direction are not two parallel directions.

[0171] The cross-sectional shape of the capacitor panel in this embodiment can be triangular to fit the structure of the annular pickup grille 132. For example, the first direction can be parallel to the base of the triangular cover plate 133 (see reference). Figure 13 The second direction is perpendicular to the bottom edge of the cover plate 133 (as shown in the y-direction). Figure 13 (As shown in the x-direction).

[0172] For example, the capacitive panel may have three touch buttons 1331 spaced apart along a first direction (e.g., the y-direction), namely a first pad 133a, a second pad 133b, and a third pad 133c, and three touch buttons 1331 spaced apart along a second direction (e.g., the x-direction), namely a fourth pad 133d, a second pad 133b, and a fifth pad 133e. The first pad 133a is located on the side above the second pad 133b, and the third pad 133c is located on the side below the second pad 133b.

[0173] The internal circuit structure of the capacitor panel can be directly referred to in the relevant content of the existing technology, and will not be repeated here.

[0174] The touch button 1331 (also known as a pad) set on the capacitive panel can be a capacitive sensor (which can be called a second capacitive sensor to distinguish it from the capacitive sensor 171 on the circuit board 17, i.e., the first capacitive sensor).

[0175] The self-capacitance principle of a single second capacitive sensor is as follows: when a user touches the touch button 1331 on the capacitive panel with their finger, the capacitance of the finger will be superimposed on the capacitive sensor, i.e., the second capacitive sensor, thereby increasing the capacitance (also known as the capacitance value) of the capacitive panel.

[0176] Figure 14 This is a schematic diagram illustrating the principle of a single touch button detecting the proximity of a finger. Figure 15 This is the logic diagram for detecting long press and swipe gestures. (Refer to...) Figure 14 and Figure 15 As shown, the principle behind single-pad finger proximity detection is as follows: The capacitance value (CAP) of a single pad is used to determine if a finger is close to it. For example, if the capacitance value (CAP) of a single pad is greater than the finger contact threshold (CAP0), then a finger is considered close; otherwise, it's considered not close (the finger is moving away). If the duration (t) for which CAP is greater than CAP0 is greater than the time threshold (t0), then it's considered a long press; otherwise, it's identified as a finger swipe. Figure 14 In the figure, curve q represents the relationship between capacitance and touch time.

[0177] Figure 16 This is a logic diagram for detecting long-press events and long-press positions on touch buttons. (Refer to...) Figure 16 As shown, it can be understood that when the capacitive sensor in the capacitive panel, i.e. the second capacitive sensor, detects a long press action on the capacitive panel, i.e. a long press event, it continues to detect the position with the largest pad capacitance value corresponding to the long press event. For example, the position with the largest pad capacitance value corresponding to the long press time can be detected by the capacitive sensor 171 on the circuit board 17 inside the ear cup, thereby determining the long press position.

[0178] Figure 17This is a logic diagram for detecting finger swipes and partial touches. (Refer to...) Figure 17 As shown, when a single pad detects a finger swipe, the direction of the finger swipe can be determined by detecting the relationship between the swipe times (hereinafter referred to as pad times) of each of the multiple pads along a first or second direction. For example, refer to... Figure 17 As shown, when the time of the first pad 133a is detected > the time of the second pad 133b > the time of the third pad 133c, or the time of the first pad 133a < the time of the second pad 133b < the time of the third pad 133c, it is recognized as a vertical swipe gesture, i.e., a swipe gesture along the y-direction. When the time of the fourth pad 133d is detected > the time of the second pad 133b > the time of the fifth pad 133e, or the time of the fourth pad 133d < the time of the second pad 133b < the time of the fifth pad 133e, it is recognized as a horizontal swipe gesture, i.e., a swipe gesture along the x-direction. If none of the above pad events are detected, it is recognized as a partial touch time.

[0179] The following illustrates one type of gesture interaction:

[0180] In response to a user's long touch (i.e., long press) operation, perform any one of the following functions: noise reduction, pass-through, and on / off action. For example, when the first pad 133a is long-touched, noise reduction is performed; when the second pad 133b is long-touched, pass-through is performed; and when the third pad 133c is long-touched, on / off action is performed.

[0181] In response to the user's left / right ear swipe, the volume up / down action is performed. For example, when the first pad 133a, the second pad 133b, and the third pad 133c are swiped down in the opposite direction of the y-axis, the volume up action is performed, and when the third pad 133c, the second pad 133b, and the first pad 133a are swiped up in the y-axis, the volume down action is performed.

[0182] In response to a short touch (i.e., a partial touch) from the user's left or right ear, the system performs a music playback / pause (call answer / hang up) action. For example, a short touch on the first pad 133a performs a music playback / pause action, and a short touch on the second pad 133b performs a call answer / hang up action.

[0183] In response to a double tap on the left or right earbud, the action of playing the next track is executed; in response to a triple tap on the left or right earbud, the action of playing the previous track is executed. For example, when the fourth pad133d is tapped twice, the action of playing the next track is executed, and when the fourth pad133d is tapped three times, the action of playing the previous track is executed.

[0184] Understandably, the above-mentioned gesture interaction method can be operated on the capacitive panel of the left or right ear to perform functions such as noise reduction, pass-through, and on / off actions.

[0185] In this embodiment, the cover plate 133 of the earpiece is set as a capacitive panel, and multiple touch buttons 1331 are set on the capacitive panel at intervals along the first direction and the second direction. In this way, a variety of gesture actions can be designed, such as long touch, short touch, sliding along the first direction, sliding along the second direction, etc., to realize the control of different functions, thereby improving the user interaction experience, enriching the human-computer interaction methods, and enriching the user's application scenarios.

[0186] In addition, since the capacitor panel is positioned away from the sound output section 12, that is, when the earphone 10 is worn inside the ear 20, the capacitor panel is positioned away from the inner bottom wall 263 of the concha cavity 26. In this way, compared with the related technology where buttons are set on both sides of the ear rod, the interference from the ear 20 when the user operates the touch button 1331 of this embodiment is weaker, thereby improving the convenience of interaction.

[0187] This application embodiment makes reasonable use of the structure of a triangular capacitive panel. Three touch buttons 1331 are arranged along a first direction perpendicular to the bottom edge, and three touch buttons 1331 are arranged along a second direction. For example, three touch buttons 1331 are arranged at intervals along a direction perpendicular to the bottom edge. In addition, one touch button 1331 is arranged on each of the two sides of the triangle. This enables multiple human-computer interaction methods, thereby improving the user interaction experience and making it easier for the user to operate.

[0188] Example 2

[0189] Figure 18 This is a schematic diagram of another structure of the headphones provided in one embodiment of this application. Figure 19 This is a schematic diagram of another earphone structure provided in one embodiment of this application, worn inside the ear. (Refer to...) Figure 18 and Figure 19 As shown, unlike Embodiment 1, in this embodiment, a roller 19 is provided on the side of the main body 11 facing the tragus 21, and one end face of the roller 19 is used to abut against the tragus 21 (see reference). Figure 19 (As shown), in other words, the side of the main body 11 facing the tragus 21 can contact the tragus 21 through the end face of the roller 19. It can be understood that the end face of the roller 19 can achieve surface-to-surface contact with the tragus 21, thereby ensuring the contact effect of the tragus 21 with the main body 11.

[0190] Among them, roller 19 can rotate around its own axis (see reference). Figure 19 As shown in Figure 1, the headphone 10 can be rotated to switch its functions. For example, when rotated clockwise (refer to Figure 10), the headphone 10 can switch its functions. Figure 19Rotating the scroll wheel 19 (in the direction indicated by the middle arrow m) will increase the volume. Rotating it counter-clockwise (refer to...) will increase the volume. Figure 19 Rotating the scroll wheel 19 in the opposite direction (as indicated by the middle arrow m) will perform the volume down action.

[0191] In this embodiment, a roller 19 is provided on one side of the main body 11. On the one hand, the function of the earphone 10 can be switched, that is, the human-computer interaction function can be realized. On the other hand, the end face of the roller 19 abuts against the tragus 21 to ensure the stability of the main body 11 in the ear 20.

[0192] Additionally, roller 19 can move along its own axis (see reference). Figure 19 The scroll wheel 19 is configured as a button by moving in the direction shown in the middle (l).

[0193] For example, a long press of scroll wheel 19 performs noise reduction / passthrough / on / off actions. A short press of scroll wheel 19 performs music play / pause actions. A double short press of scroll wheel 19 plays the next track, and a triple short press of scroll wheel 19 plays the previous track.

[0194] It is understood that the roller 19 here is a mechanical switch structure. Therefore, the internal structure and working principle of the roller 19 can be referred to the existing mechanical switches, and will not be described in detail here.

[0195] To facilitate pressing the roller 19, a portion of the end face of the roller 19 may protrude from the cover plate 133 of the main body 11 (see reference). Figure 18 As shown), when the earphone 10 is worn inside the ear 20, a portion of the roller 19 can protrude from the tragus 21 (see reference). Figure 19 As shown in the figure, this allows the user to conveniently press the scroll wheel 19 inwards from the end face of the scroll wheel 19 to switch the relevant functions of the earphone 10.

[0196] This application embodiment sets the scroll wheel 19 as a button that can move along its own axis to further enrich the human-computer interaction method, enrich the usage scenarios of the earphone 10, and realize the multi-functional switching of the earphone 10.

[0197] The control position and control method of the earphone 10 in this embodiment can also be directly adopted from earphones 10 in related technologies. For example, the earphone 10 in this embodiment can also include an ear stem, one end of which is connected to the side wall of the cover plate 133 or the second housing 1132. Multiple touch sensors on the ear stem enable control of different functions of the earphone 10 through gestures such as long press, short press, or swipe.

[0198] For example, there are two touch sensors on the earpiece. When the user presses and holds one of the touch sensors, the noise cancellation function of the earphone 10 can be turned on or off. When the user presses and holds the other touch sensor, the earphone 10 can be turned on or off. When the user slides from the first touch sensor to the second touch sensor, the volume of the earphone 10 increases. When the user slides from the second touch sensor to the first touch sensor, the volume of the earphone 10 decreases.
