[0002] This application claims priority to Chinese Patent Application No. 202410999555.5, filed on July 24, 2024, entitled "Headphones", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication equipment technology, and specifically relates to an earphone. Background Technology

[0004] Currently, headphones are categorized into open-ear wearable headphones and in-ear headphones. Open-ear wearable headphones do not insert into the ear canal, resulting in relatively poor sound quality and active noise cancellation. In-ear headphones, on the other hand, fit snugly into the ear canal, leading to poor comfort, difficulty hearing external sounds, and potential hearing damage. Therefore, the wearing methods of headphones in these technologies are relatively limited and cannot meet the needs of users in various situations. Summary of the Invention

[0005] This application aims to provide an earphone that at least solves the problem that earphones in the related technology have a single wearing method and cannot meet the user's usage needs in different situations.

[0006] In a first aspect, embodiments of this application provide an earphone, comprising: a wearing part for wearing on the ear of a wearer; a first sound-emitting part connected to the wearing part, the first sound-emitting part having a first sound-emitting hole; a second sound-emitting part connected to the wearing part, the second sound-emitting part having a second sound-emitting hole; the earphone having a first wearing state and a second wearing state; in the first wearing state, the earphone emits sound through the first sound-emitting hole, at least a portion of the first sound-emitting part being located inside the ear canal; in the second wearing state, the earphone emits sound through the second sound-emitting hole, the second sound-emitting part being located outside the ear canal.

[0007] Secondly, embodiments of this application provide an earphone assembly, including: earphones as described in any of the first aspects.

[0008] Thirdly, embodiments of this application provide an electronic device, including: an earphone as described in any of the first aspects; or an earphone assembly as described in the second aspect.

[0009] In the embodiments of this application, the headphones include a wearing part, a first sound-emitting part and a second sound-emitting part connected to the wearing part. The headphones are worn on the wearer's ear through the wearing part, improving the reliability of the headphones. The first sound-emitting part emits sound through a first sound-emitting hole, and the second sound-emitting part emits sound through a second sound-emitting hole. The headphones have a first wearing state and a second wearing state. When the headphones are in the first wearing state, the headphones emit sound through the first sound-emitting hole, that is, the first sound-emitting part is in use. The first sound-emitting part extends into the wearer's ear canal, thereby giving the headphones better sound quality, better sound isolation, and better noise reduction. When the headphones are in the second wearing state, the headphones emit sound through the second sound-emitting hole, that is, the second sound-emitting part is in use. The second sound-emitting part is located outside the wearer's ear canal and aligned with the ear canal, improving wearing comfort. At the same time, it also allows the wearer to synchronize with ambient sound, improving safety. This allows users to switch between wearing modes according to different usage needs.

[0032] The headphones according to an embodiment of this application are described below with reference to Figures 1-15.

[0033] As shown in Figures 1 to 13, an earphone according to some embodiments of this application includes: a wearing part 1 for wearing on the ear of a wearer; a first sound-emitting part 2 connected to the wearing part 1, the first sound-emitting part 2 having a first sound-emitting hole 20; and a second sound-emitting part 3 connected to the wearing part 1, the second sound-emitting part 3 having a second sound-emitting hole 30; the earphone has a first wearing state and a second wearing state; in the first wearing state, the earphone emits sound through the first sound-emitting hole 20, and at least a portion of the first sound-emitting part 2 is located inside the ear canal; in the second wearing state, the earphone emits sound through the second sound-emitting hole 30, and the second sound-emitting part 3 is located outside the ear canal.

[0034] In the embodiments of this application, the headphones include a wearing part 1, a first sound-emitting part 2 and a second sound-emitting part 3 connected to the wearing part 1. The headphones are worn on the wearer's ear through the wearing part 1, which improves the reliability of the headphones. The first sound-emitting part 2 emits sound through a first sound-emitting hole 20, and the second sound-emitting part 3 emits sound through a second sound-emitting hole 30. The headphones have a first wearing state and a second wearing state. When the headphones are in the first wearing state, the headphones emit sound through the first sound-emitting hole 20, that is, the first sound-emitting part 2 is in the used state. The first sound-emitting part 2 extends into the wearer's ear canal, thereby giving the headphones better sound quality, better sound isolation, and better noise reduction. When the headphones are in the second wearing state, the headphones emit sound through the second sound-emitting hole 30, that is, the second sound-emitting part 3 is in the used state. The second sound-emitting part 3 is located outside the wearer's ear canal and aligned with the ear canal, which improves the wearing comfort and also allows the wearer to synchronize with the ambient sound, improving the safety of use. This allows users to switch between wearing modes according to different usage needs.

[0035] It should be noted that at least a portion of the first sound-emitting part 2 can extend into the wearer's ear canal. When the second sound-emitting part 3 is used, it is located outside the wearer's ear canal, forming an open, non-ear-penetrating wearing method.

[0036] As shown in Figures 1, 2 and 3, according to some embodiments of this application, optionally, the first sound-emitting part 2 and the second sound-emitting part 3 are located at both ends of the wearing part 1, and the first sound-emitting hole 20 and the second sound-emitting hole 30 are arranged facing different sides of the wearing part 1.

[0037] In this embodiment, the first sound-emitting part 2 and the second sound-emitting part 3 are located at opposite ends of the wearing part 1. In different wearing states, one of the first sound-emitting part 2 and the second sound-emitting part 3 can provide sound to the wearer, while the other acts as a support for the wearer's ear, improving the stability of the fit. The first sound-emitting hole 20 and the second sound-emitting hole 30 are positioned facing different sides of the wearing part 1, thus facilitating adaptation to different wearing states. In the first wearing state, the first sound-emitting hole 20 is located inside the ear canal, and in the second wearing state, the second sound-emitting hole 30 is directly opposite the ear canal.

[0038] Optionally, the first sound outlet 20 is located on the side of the first sound outlet 2 away from the second sound outlet 3, and the second sound outlet 30 is located on the side of the second sound outlet 3 away from the first sound outlet 2, so that the first sound outlet 20 and the second sound outlet 30 are opposite to each other, thereby facilitating adaptation to different wearing states, so that the first sound outlet 20 can be located in the ear canal in the first wearing state, and the second sound outlet 30 can be directly facing the ear canal in the second wearing state.

[0039] As shown in Figure 3, according to some embodiments of this application, optionally, the wearing part 1 includes: a first connecting end 10 connected to the first sound output part 2; a second connecting end 12 connected to the second sound output part 3; and a bridge part 14 connecting the first connecting end 10 and the second connecting end 12. The bridge part 14 is bent toward the same side of the first sound output part 2 and the second sound output part 3, so that the included angle between the bridge part 14 and the first connecting end 10 is greater than or equal to 90° and less than 180°, and the included angle between the bridge part 14 and the second connecting end 12 is greater than or equal to 90° and less than 180°.

[0040] In this embodiment, the wearing part 1 includes a first connecting end 10, a second connecting end 12, and a bridge part 14. The first connecting end 10 is connected to the first sound output part 2, the second connecting end 12 is connected to the second sound output part 3, and the bridge part 14 is connected to the first connecting end 10 and the second connecting end 12. The bridge part 14 is bent toward the same side of the first sound output part 2 and the second sound output part 3, so that the bridge part 14 is bent relative to the first connecting end 10 and the second connecting end 12, thereby making the angle between the bridge part 14 and the first connecting end 10 greater than or equal to 90° and less than 180°, and the angle between the bridge part 14 and the second connecting end 12 greater than or equal to 90° and less than 180°. That is, when wearing, the bridge part 14 is not perpendicular to the wearer's face, thereby facilitating the adjustment of the wearing position of the headphones in the first wearing state or the second wearing state.

[0041] It is understandable that, since the first sound output section 2 needs to be inserted into the wearer's ear canal in the first wearing state, while the second sound output section 3 does not need to be inserted into the wearer's ear canal in the second wearing state and is located outside the wearer's ear canal and aligned with the ear canal, the first sound output section 2 and the second sound output section 3 have different requirements for the length of the wearing section 1 when worn. This application bends the bridge section 14 so that the bridge section 14 is nearly parallel to the wearer's face rather than perpendicular to it, thereby facilitating the adjustment of the wearing position in the two wearing states. This avoids the situation where the bridge section 14 cannot be adjusted due to interference between the bridge section 14 and the wearer's ear when the bridge section 14 is perpendicular to the first sound output section 2 and when the sound output is open.

[0042] Alternatively, when worn, the bridge portion 14 is nearly parallel to the wearer's face.

[0043] According to some embodiments of this application, the bridge portion 14 may optionally be U-shaped.

[0044] In this embodiment, the bridge portion 14 is U-shaped for ease of wearing.

[0045] As shown in Figures 1, 2, 3, 4 and 5, according to some embodiments of this application, optionally, the first sound-emitting part 2 and the second sound-emitting part 3 are clamped on both sides of the wearer's ear by the wearing part 1; wherein, the first sound-emitting part 2 and the second sound-emitting part 3 at both ends of the wearing part 1 are respectively adapted to the ear on different sides of the wearer.

[0046] In this embodiment, the earphone has an ear clip structure, which can be clipped onto the wearer's ear via the first sound output part 2 and the second sound output part 3 in both the first and second wearing states, thereby improving the reliability of the earphone. As shown in Figures 4 and 5, the first sound output part 2 and the second sound output part 3 at both ends of the wearing part 1 are adapted to the wearer's ears on different sides. That is, as shown in Figure 4, for the same earphone, when using the first sound output part 2 to output sound, it is worn on one ear of the wearer (e.g., the wearer's left ear), and as shown in Figure 5, when using the second sound output part 3 to output sound, it is worn on the other ear of the wearer (e.g., the wearer's right ear).

[0047] As shown in Figures 6 to 13, according to some embodiments of this application, optionally, the earphone further includes: a rotating part 4, the rotating part 4 including a first sound output part 2 and a second sound output part 3, the wearing part 1 including a wearing side 16, the rotating part 4 being disposed at one end of the wearing part 1 and rotatably connected to the wearing part 1, so that the first sound output part 2 faces the wearing side 16 or the second sound output part 3 faces the wearing side 16; in the first wearing state, the first sound output part 2 is disposed facing the wearing side 16, and in the second wearing state, the second sound output part 3 is disposed facing the wearing side 16.

[0048] In this embodiment, as shown in Figures 6, 7, 10 and 11, the earphone further includes a rotating part 4, which includes a first sound output part 2 and a second sound output part 3. The rotating part 4 is rotatably connected to the wearing part 1, so that the position of the first sound output part 2 relative to the wearing part 1 and the position of the second sound output part 3 relative to the wearing part 1 can change with the rotation of the rotating part 4, thereby allowing the earphone to switch between a first wearing state and a second wearing state. As shown in Figures 8 and 12, in the first wearing state, the first sound-emitting part 2 is positioned facing the wearing side 16 (e.g., the side that fits against the face in Figures 8 and 12), so that the first sound-emitting part 2 is adapted to the wearing part 1. When the wearing part 1 is worn on the wearer's ear, the first sound-emitting part 2 extends into the wearer's ear canal. As shown in Figures 9 and 13, in the second wearing state, the second sound-emitting part 3 is positioned facing the wearing side 16 (e.g., the side that fits against the face in Figures 9 and 13), so that the second sound-emitting part 3 is adapted to the wearing part 1. When the wearing part 1 is worn on the wearer's ear, the second sound-emitting part 3 is located outside the wearer's ear canal and aligned with the ear canal.

[0049] Understandably, in the first wearing state, the first sound output part 2 is adapted to the wearing part 1, that is, when the wearing part 1 is worn on the wearer's ear, the first sound output part 2 extends into the ear canal to achieve in-ear sound output. In the second wearing state, the second sound output part 3 is adapted to the wearing part 1, that is, when the wearing part 1 is worn on the wearer's ear, the second sound output part 3 is aligned with the ear canal to achieve open-ear sound output.

[0050] As shown in Figure 6, according to some embodiments of this application, optionally, the first sound hole 20 and the second sound hole 30 are located on both sides of the rotation axis L of the rotating part 4.

[0051] In this embodiment, the first sound outlet 20 and the second sound outlet 30 are located on both sides of the rotation axis L of the rotating part 4, so that when the rotating part 4 is rotated, the positions of the first sound outlet 20 and the second sound outlet 30 rotate with the rotating part 4, so that the first sound outlet 20 faces the wearer's ear canal or the second sound outlet 30 faces the wearer's ear canal, thereby realizing the switching between the first wearing state and the second wearing state.

[0052] It is understandable that when the headphones are worn on the wearer's ear, the side of the wearing part 1 facing the ear canal is the wearing side 16. When the first sound hole 20 faces the wearing side 16, the first sound hole 2 is adapted to the wearing part 1. When the second sound hole 30 faces the wearing side 16, the second sound hole 3 is adapted to the wearing part 1.

[0053] As shown in Figures 6 to 13, according to some embodiments of this application, the earphones may optionally have an ear-hook structure.

[0054] In this embodiment, the earphone has an ear-hook structure, which allows it to be hung on the wearer's ear when worn, improving wearing reliability and comfort.

[0055] As shown in Figures 14 and 15, according to some embodiments of this application, optionally, the headphones further include: a speaker 5, disposed in at least one of the first sound output section 2 and the second sound output section 3; a circuit board 6, disposed in one of the first sound output section 2 and the second sound output section 3, and electrically connected to the speaker 5; a power supply section 7, disposed in one of the first sound output section 2 and the second sound output section 3, and electrically connected to the speaker 5 and the circuit board 6, for supplying power to the speaker 5; in the first wearing state, the speaker 5 emits sound through the first sound output hole 20, and in the second wearing state, the speaker 5 emits sound through the second sound output hole 30.

[0056] In this embodiment, the headphones also include a speaker 5, a circuit board 6, and a power supply unit 7. The speaker 5 is disposed in at least one of the first sound output section 2 and the second sound output section 3. The circuit board 6 is disposed in one of the first sound output section 2 and the second sound output section 3. The power supply unit 7 is disposed in one of the first sound output section 2 and the second sound output section 3. The circuit board 6 is electrically connected to the speaker 5, and the power supply unit 7 is electrically connected to the speaker 5 and the circuit board 6, thereby supplying power to the speaker 5. At the same time, the speaker 5 can emit sound through the first sound output hole 20 in the first wearing state and emit sound through the second sound output hole 30 in the second wearing state, thereby realizing in-ear wearing and fully open wearing respectively.

[0057] In a specific application, the circuit board 6 is located inside the first sound output section 2, and the power supply section 7 is located inside the second sound output section 3.

[0058] As shown in Figure 14, according to some embodiments of this application, optionally, the speaker 5 is disposed in the first sound outlet 2, and the earphone further includes: a sound guide tube 8, one end of which is connected to the second sound outlet 30, and the other end is disposed opposite to the speaker 5; a valve body 9, disposed in the first sound outlet 2, for switching the communication direction of the speaker 5 so that the speaker 5 is connected to the first sound outlet 20, or connected to the second sound outlet 30 through the sound guide tube 8.

[0059] In this embodiment, the speaker 5 is disposed within the first sound outlet 2 and can communicate with the second sound outlet 3 via the sound guide tube 8 and the valve body 9. Specifically, the sound guide tube 8 is disposed within the wearing part 1, with one end communicating with the second sound outlet 30 and the other end positioned opposite the speaker 5. By switching the valve body 9, the speaker 5 can communicate with the first sound outlet 20 (the direction of sound transmission is shown by the arrow at the first sound outlet 20 in Figure 14) or with the second sound outlet 30 (the direction of sound transmission is shown by the arrow at the second sound outlet 30 in Figure 14). Thus, the same speaker 5 can output sound from both the first sound outlet 20 and the second sound outlet 30, reducing the number of speakers 5, lowering the overall weight of the headphones, and improving wearing comfort.

[0060] Optionally, the speaker 5 includes a sound outlet cavity with a first opening and a second opening. The first opening communicates with a first sound outlet 20, and the second opening communicates with a sound guide tube 8. A valve body 9 is disposed at the first and second openings to switch the opening and closing states of the first and second openings. Specifically, in the first wearing state, the valve body 9 opens the first opening, allowing the speaker 5 to communicate with the first sound outlet 20 through the first opening, thus enabling sound to be emitted from the first sound outlet 20. In the second wearing state, the valve body 9 opens the second opening, allowing the speaker 5 to communicate with the second sound outlet 30 through the sound guide tube 8, thus enabling sound to be emitted from the second sound outlet 30.

[0061] According to some embodiments of this application, the valve body 9 may optionally include a solenoid valve.

[0062] In this embodiment, the valve body 9 includes a solenoid valve, which enables automated control of the opening and closing states of the valve body 9.

[0063] As shown in Figure 15, according to some embodiments of this application, optionally, the speaker 5 includes: a first speaker 50 disposed in the first sound outlet 2 and communicating with the first sound outlet 20; a second speaker 52 disposed in the second sound outlet 3 and communicating with the second sound outlet 30; in the first wearing state, the power supply unit 7 is electrically connected to the first sound outlet 2 and is used to supply power to the first sound outlet 2; in the second wearing state, the power supply unit 7 is electrically connected to the second sound outlet 3 and is used to supply power to the second sound outlet 3.

[0064] In this embodiment, the speaker 5 includes a first speaker 50 and a second speaker 52. The first speaker 50 is disposed within the first sound-emitting section 2 and communicates with the first sound-emitting hole 20. The second speaker 52 is disposed within the second sound-emitting section 3 and communicates with the second sound-emitting hole 30. Thus, in the first wearing state, the power supply unit 7 is electrically connected to the first speaker 50 to supply power to the first speaker 50, thereby enabling sound to be emitted from the first sound-emitting hole 20 through the first speaker 50. In the second wearing state, the power supply unit 7 is electrically connected to the second speaker 52 to supply power to the second speaker 52, thereby enabling sound to be emitted from the second sound-emitting hole 30 through the second speaker 52. In this embodiment, the first speaker 50 and the second speaker 52 are respectively disposed within the first sound-emitting section 2 and the second sound-emitting section 3, which is beneficial to improving the sound quality.

[0065] According to some embodiments of this application, the wearing part 1 may optionally include a shape memory alloy component.

[0066] In this embodiment, the wearing part 1 includes a shape memory alloy component, which allows the wearing part 1 to be constructed into a more ergonomic shape, thereby improving wearing comfort.

[0067] According to some embodiments of this application, optionally, the first sound output section 2 is an in-ear structure or a semi-in-ear structure; the second sound output section 3 is an open-type wearable stereo structure.

[0068] In this embodiment, the first sound output section 2 includes an in-ear structure as shown in Figures 6 to 9 or a semi-in-ear structure as shown in Figures 10 to 13. The in-ear structure improves sound quality, while the semi-in-ear structure improves wearing comfort. The second sound output section 3 is an open-back wearable stereo structure, which improves wearing comfort and allows for synchronization with ambient sound during wear, thus enhancing wearing safety.

[0069] This application also proposes an earphone assembly, including: earphones as proposed in any of the above embodiments, thus having all the beneficial effects of earphones.

[0070] Optionally, the earphone assembly includes a charging case that can charge the earphones.

[0071] Optionally, the earphone case includes a charging case in which the earphones can be installed.

[0072] This application also proposes an electronic device, including: an earphone as proposed in any of the above embodiments; or an earphone assembly as proposed in any of the above embodiments, thus having all the beneficial effects of an earphone or an earphone assembly.

[0073] Alternatively, electronic devices include mobile phones, fitness trackers, tablets, etc.

[0074] According to one embodiment of this application, as shown in Figures 1 to 5, the earphone is a clip-on earphone, with two ends being an in-ear end (e.g., a first sound output part 2) and an open-wearable stereo (OWS) end (e.g., a second sound output part 3). Each end has a sound output hole (e.g., a first sound output hole 20 and a second sound output hole 30), which are connected by a U-shaped bridge (e.g., a wearing part 1).

[0075] The U-shaped bridge allows for ergonomic fit when the headphones are worn in different positions. Because it needs to accommodate both wearing positions, the U-shaped bridge is approximately parallel to the face, making it easy to adjust its length to suit different users.

[0076] As shown in Figure 4, in the first wearing state, the earphone is worn in the left ear as an in-ear earphone. As shown in Figure 5, when using it as an OWS earphone, it is worn in the right ear in the second wearing state. The OWS end is aligned with the ear canal for OWS wearing.

[0077] One implementation of the dual sound outlets in this embodiment is shown in Figure 14: The in-ear end (shown as a semi-in-ear design, but also applicable to in-ear models) houses the speaker (e.g., loudspeaker 5), the mainboard (e.g., circuit board 6), and other components such as the microphone (MIC). This embodiment adds an electromagnetically driven switching valve (e.g., valve body 9) to the in-ear end.

[0078] The OWS (Output Switch) end of the earphone is typically designed to house a battery (e.g., power supply unit 7) or be used purely for clip-on earphone applications. This embodiment adds an OWS sound outlet (e.g., a second sound outlet 30) to the OWS end. The second sound outlet 30 is oriented opposite to the first sound outlet 20 at the in-ear end, located on the outside of the OWS end. This ensures that the second sound outlet 30 is directly facing the ear canal when the OWS is worn.

[0079] The U-shaped bridge is the connecting part, containing shape memory alloy and wire 70. Wire 70 is used for electrical connection between the components on both sides. In this embodiment, an air duct (e.g., sound duct 8) is added in the middle of the U-shaped bridge to guide the sound from the speaker to the second sound outlet 30 at the OWS end.

[0080] Work process:

[0081] When worn in the ear (e.g., in the first wearing state), the switching valve closes the channel connecting the air tube, the air tube is inactive, and only the first sound outlet 20 at the ear can produce sound.

[0082] When worn in OWS mode (e.g., the second wearing state), the switching valve opens the channel connecting the air duct, the air duct is activated, and only the second sound outlet 30 at the OWS end produces sound.

[0083] Another implementation of the dual sound outlets in this embodiment is shown in Figure 15. The in-ear end (shown as a semi-in-ear type, but also applicable to in-ear type) is conventionally designed to house the speaker (e.g., the first speaker 50), the main board, and other components such as the microphone.

[0084] The OWS (Output Switch) end of the earphone is typically designed to house batteries or be used purely for clip-on earphone applications. This embodiment adds a speaker (e.g., a second speaker 52) and a second sound outlet 30 to the OWS end. The second sound outlet 30 is oriented opposite to the first sound outlet 20 on the in-ear end, located on the outside of the OWS end. This ensures that the sound outlet is directly facing the ear canal when the OWS is worn.

[0085] The U-shaped bridge is the connecting part, containing shape memory alloy and wire 70. To accommodate two wearing positions, the U-shaped bridge is approximately parallel to the face, allowing for easy length adjustment to fit different individuals. Wire 70 is used for electrical connections between the two side components.

[0086] Operating procedure: When worn in-ear, power is supplied only to the speaker at the in-ear end, and sound is only produced at the first sound outlet 20 at the in-ear end. When worn in OWS mode, power is supplied only to the speaker at the OWS end, and sound is only produced at the second sound outlet 30 at the OWS end.

[0087] The embodiments proposed in this application, by adding a sound outlet and redesigning the ear clip's ergonomics, allow for compatibility with both OWS and in-ear headphone types by simply changing the wearing direction. The headphone structure is simple and the compatibility method is convenient.

[0088] As shown in Figures 6 and 7, according to one embodiment of this application, the earphone is an ear-hook type earphone. Two sound outlets (e.g., a first sound outlet 20 and a second sound outlet 30) are provided in the rotating part 4 of the ear-hook earphone. The rotating part 4 is designed to be rotatable. Different rotation states correspond to both True Wireless Stereo (TWS) and OWS wearing postures.

[0089] The implementation scheme for dual sound holes can be referred to the above embodiments.

[0090] As shown in Figures 10 to 13, according to one embodiment of this application, based on the above-described ear-hook headphone embodiment, the in-ear end is changed to a semi-in-ear structure. The semi-in-ear wearing causes less pressure on the ear and is more comfortable.

[0091] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0092] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
