Description
Technical Field
[0001] This application relates to the technical field of headphones, and more particularly to a headphone and headphone assembly. Background Technology
[0002] The headphones may include an earpiece and an earpiece stem, which are connected together. A speaker is positioned within the housing space enclosed by the earpiece and is used to play audio.
[0003] Typically, headphones can only be worn in one way, which limits their flexibility. Utility Model Content
[0004] The embodiments of this application disclose an earphone and an earphone assembly. The earphone can be worn in both in-ear and clip-on styles, improving the wearing flexibility of the earphone.
[0005] On one hand, an earphone includes an earphone head, a speaker, a damping structure, and an earphone stem. The earphone head surrounds a first receiving space. The speaker is located within the first receiving space. The damping structure includes a pivot and a bushing. The pivot extends along a third direction. The bushing extends circumferentially along the pivot and surrounds at least a portion of the pivot. The bushing and the pivot are rotatably connected. The earphone stem includes a fixed stem and a rotating stem. The fixed stem is connected to the earphone head, and one of the fixed stem and the rotating stem is connected to the bushing, while the other is connected to the pivot. The rotating stem is rotatable relative to the fixed stem to switch the earphone between an in-ear mode and an ear-clamping mode. When the earphone is in the in-ear mode, the rotating stem extends along the length of the fixed stem. When the earphone is in the ear-clamping mode, a preset angle is formed between the rotating stem and the fixed stem to clamp the auricle. The pivot and the bushing are interference-fitted to maintain the relative position of the rotating stem and the fixed stem through friction.
[0006] In some possible implementations, a first through hole is provided at the end of the retaining handle away from the earphone head, and the first through hole extends through the retaining handle in a third direction. A bushing is embedded in the first through hole and connected to the retaining handle. In a third direction, at least one end of the rotating shaft protrudes from the retaining handle and is connected to the rotating handle.
[0007] In some possible implementations, the bushing includes a bushing body and a limiting portion. The bushing body extends circumferentially along the rotating shaft and surrounds at least a portion of the rotating shaft. The bushing body and the rotating shaft are rotatably connected, and the bushing body and the rotating shaft are interference-fitted. The limiting portion is connected to the bushing body. A limiting groove is also formed at the end of the fixing handle away from the earphone head, and the limiting groove communicates with a first through hole. The bushing body is embedded in the first through hole, and the limiting portion is embedded in the limiting groove. The limiting groove is used to restrict the bushing from rotating relative to the fixing handle in a third direction.
[0008] In some possible implementations, the bushing body and the limiting part are integrally formed.
[0009] In some possible implementations, the retaining handle includes a retaining handle body and a protrusion located on the side of the retaining handle body away from the earphone head. A first through hole and a limiting groove are formed on the protrusion. A groove is formed at one end of the rotating handle, and the protrusion is embedded in the groove. At least one end of the rotating shaft protrudes from the protrusion and is connected to the rotating handle.
[0010] In some possible implementations, the rotating handle includes a rotating handle body, a first sub-part, and a second sub-part. The first and second sub-parts are disposed on one side of the rotating handle body along its extension direction and are connected to the rotating handle body. The first and second sub-parts are arranged opposite each other along a third direction to form a groove. A second through hole is formed on the first sub-part, penetrating the first sub-part along a third direction. A third through hole is formed on the second sub-part, penetrating the second sub-part along a third direction. The second and third through holes are arranged opposite each other in the third direction. The second through hole is a flat hole, and the end of the rotating shaft near the second through hole is a first flat part, which is embedded in the second through hole. And / or, the third through hole is a flat hole, and the end of the rotating shaft near the third through hole is a second flat part, which is embedded in the third through hole.
[0011] In some possible implementations, the bushing is located within the first through hole along a third direction.
[0012] In some possible implementations, at least one of the shaft and bushing is made of metal.
[0013] In some possible implementations, the rotating handle includes a first surface that faces the fixed handle when the earphone is in the clip-on position. The first surface includes a concave arc surface.
[0014] In some possible implementations, the earphone head includes a sound-emitting plate with a first speaker hole. The first speaker hole extends through the sound-emitting plate along its thickness and is located away from the earphone stem. Along the direction from the earphone stem to the earphone head, the sound-emitting plate gradually moves away from the fixed stem.
[0015] In some possible implementations, when the earphone is in the ear-clamping position and the angle between the rotating handle and the fixed handle is at its minimum, the maximum distance between the rotating handle and the fixed handle is the first distance, and the value of the first distance ranges from 3 mm to 6 mm.
[0016] On the other hand, embodiments of this application provide an earphone assembly. The earphone assembly includes two earphones as described above and a charging case. The charging case is used to hold the earphones and to charge the earphones.
[0017] The embodiments of this application have at least the following beneficial effects:
[0018] In the embodiments of this application, the bushing and the rotating shaft can rotate relative to each other in a third direction. One of the fixed handle and the rotating handle is connected to the bushing, and the other is connected to the rotating shaft, so that the rotating handle can rotate relative to the fixed handle in a third direction, so that the earphone can switch between in-ear and clip-on modes, thereby enabling the earphone to have both in-ear and clip-on wearing methods, improving the wearing flexibility of the earphone.
[0019] In this way, users can change the shape of the headphones according to their needs, making the headphones suitable for different scenarios such as sports, commuting, meetings, and leisure. The operation is simple and improves the applicability of the headphones.
[0020] The hinge and bushing are designed with an interference fit to maintain the relative position of the rotating handle and the fixed handle through friction. This allows the rotating handle to move to any position within its rotation range, enabling users to adjust the angle between the rotating handle and the fixed handle in the ear-clamping configuration to their liking, thus improving the earphone's usability and wearing comfort. Furthermore, the simple structure helps reduce the cost of the earphones. Attached Figure Description

Detailed Implementation
[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0037] In this application, the terms "upper," "left," "right," "front," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0038] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0039] Furthermore, the terms "installation," "setup," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0040] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.
[0041] Traditional headphone wearing methods can be roughly divided into in-ear (including full in-ear and semi-in-ear), ear-hook, and clip-on styles, each of which has certain limitations in use.
[0042] For example, in-ear headphones offer good sound quality and noise isolation, but prolonged wear can cause ear canal discomfort and pose safety risks when needing to hear external sounds. Ear-hook and clip-on headphones, while providing good external sound access, suffer from poor sound quality in noisy environments.
[0043] Traditional headphones typically only have one wearing method, which cannot meet the needs of users in different scenarios and lacks wearing flexibility.
[0044] Based on this, embodiments of this application provide an earphone assembly, which includes two earphones 100 and a charging case (not shown in the figure). The charging case is used to house the earphones 100 and to charge the earphones 100.
[0045] Understandably, the earphone 100 includes an earphone battery, and the charging case can charge the earphone battery. After the earphone 100 is separated from the charging case, the earphone battery can power the earphone 100's speaker and Bluetooth chip, enabling the earphone to connect to other devices (such as mobile phones or computers) and to achieve audio playback functions.
[0046] For example, the charging case may include a charging case body and a flip cover, the flip cover and the charging case body being rotatably connected, allowing the earphones 100 to be placed within a receiving cavity enclosed by the charging case body and the flip cover. The charging case may also include a charging case battery, which may be disposed within the receiving cavity enclosed by the charging case body. An external power source can charge the charging case battery, enabling the charging case to charge the earphones 100.
[0047] The embodiments of this application do not further limit the specific form of the charging case; the following is an example of the earphone 100.
[0048] Figure 1 This is a schematic diagram of the structure of an earphone in an in-ear configuration provided in some embodiments of this application. Figure 2 This is a schematic diagram of the structure of the earphone in the ear-clamping configuration provided in some embodiments of this application. Figure 3 for Figure 2 A schematic diagram of the exploded structure of the headphones.
[0049] In some examples, such as Figure 1 and Figure 2 As shown, the headphone 100 includes a headphone head 110, a speaker (not shown in the figure), a damping structure 120, and a headphone stem 130.
[0050] For example, when the earpiece heads 110 of the two earpieces 100 in the headphone assembly are the same or nearly the same, the left and right ears can be interchanged for wearing, so that there is no need to distinguish between the left and right earpieces when wearing them, thus improving the convenience of wearing them.
[0051] The earphone head 110 surrounds a first receiving space, and the speaker is located within the first receiving space. For example, the number of speakers can be one or more. When there are multiple speakers, the multiple speakers can be spaced apart within the first receiving space. The speaker can be at least one of the following: electromagnetic speaker, electrodynamic speaker, piezoelectric speaker, electrostatic speaker, ionic speaker, airflow-changing speaker, and airflow-modulated speaker.
[0052] Taking an electromagnetic loudspeaker as an example, a loudspeaker can include a voice coil, a diaphragm, and a magnet. The magnet generates a magnetic field, and the voice coil is located within this magnetic field. When currents of different magnitudes and directions flow through the voice coil, forces of different magnitudes and directions are generated between the voice coil and the magnet, causing the voice coil to vibrate. The vibration of the voice coil drives the diaphragm to vibrate, and the movement of the diaphragm produces sound. This allows the loudspeaker to convert electrical signals into sound signals, thus enabling the headphones 100 to perform audio playback.
[0053] For example, the first receiving space may also contain structures such as a Bluetooth chip and a circuit board. The earphone battery can be located in the first receiving space or in the second receiving space enclosed by the earphone stem 130.
[0054] like Figure 3 As shown, the damping structure 120 includes a shaft 121 and a sleeve 122. The shaft 121 extends in a third direction Z. The sleeve 122 extends circumferentially along the shaft 121 and surrounds at least a portion of the shaft 121. The sleeve 122 and the shaft 121 are rotatably connected. Understandably, the sleeve 122 and the shaft 121 are capable of relative rotation about a third direction Z.
[0055] Continue to refer to Figure 3 In some examples, the headphone stem 130 includes a fixed stem 131 and a rotating stem 132. The fixed stem 131 is connected to the headphone head 110. For example, the fixed stem 131 and the headphone head 110 can be a fixed connection to improve the reliability of their connection.
[0056] For example, the length of the rotating handle 132 ranges from 10 mm to 20 mm. For instance, the length of the rotating handle 132 can be 12 mm, 15 mm, or 18 mm, etc. The embodiments of this application do not further limit the length of the rotating handle 132.
[0057] One of the fixed handle 131 and the rotating handle 132 is connected to the bushing 122, and the other is connected to the rotating shaft 121. The rotating handle 132 is rotatable relative to the fixed handle 131 to allow the earphone 100 to switch between an in-ear mode and an ear-clamp mode.
[0058] For example, the fixed handle 131 can be connected to the rotating shaft 121, and the rotating handle 132 can be connected to the bushing 122. Alternatively, the fixed handle 131 can be connected to the bushing 122, and the rotating handle 132 can be connected to the rotating shaft 121.
[0059] Understandably, the bushing 122 and the rotating shaft 121 can rotate relative to each other in the third direction Z. One of the fixed handle 131 and the rotating handle 132 is connected to the bushing 122 and the other is connected to the rotating shaft 121, so that the rotating handle 132 can rotate relative to the fixed handle 131 in the third direction Z, thereby enabling the earphone 100 to switch between in-ear mode and clip-on mode.
[0060] like Figure 1 As shown, when the earphone 100 is in the in-ear position, the rotating stem 132 extends along the length direction of the fixed stem 131. For example, the length direction of the fixed stem 131 can be a first direction X. When the earphone 100 is in the in-ear position, both the rotating stem 132 and the fixed stem 131 extend along the first direction X, meaning the earphone stem 130 can extend along the first direction X. Understandably, when the earphone 100 is in the in-ear position, the angle between the rotating stem 132 and the fixed stem 131 can be 180°, 179°, or 178°, etc. The rotating stem 132 extending along the length direction of the fixed stem 131 allows the earphone 100 to be worn in an in-ear manner.
[0061] like Figure 2 As shown, when the earphone 100 is in the ear-clamping mode, a preset angle is formed between the rotating handle 132 and the fixed handle 131 to clamp the auricle.
[0062] For example, when the earphone 100 is in the ear-clamping mode, a portion of the rotating handle 132 and the earphone head 110 are located on the same side of the fixed handle 131 along the second direction Y, so that a preset angle can be formed between the rotating handle 132 and the fixed handle 131 to clamp the auricle. The first direction X and the second direction Y are perpendicular, and the third direction Z is perpendicular to the plane containing the first direction X and the second direction Y.
[0063] Understandably, the first direction X and the second direction Y can be perpendicular or approximately perpendicular; that is, the angle between the first direction X and the second direction Y can be 90°, 88°, or 89°, etc. The third direction Z can be perpendicular or approximately perpendicular to the plane containing the first direction X and the second direction Y; that is, the angle between the third direction Z and the plane containing the first direction X and the second direction Y can be 90°, 88°, or 89°, etc.
[0064] When the earphone 100 is in the ear-clamping position, the included angle between the rotating handle 132 and the fixed handle 131 can be an obtuse angle, a right angle, or an acute angle. The embodiments of this application do not further limit the value of the included angle between the rotating handle 132 and the fixed handle 131 when the earphone 100 is in the ear-clamping position.
[0065] Figure 4 These are schematic diagrams illustrating the wearing of the earphones in a clip-on configuration, as provided in some embodiments of this application. Figure 4As shown, when the earphone 100 is in the ear-clamping mode, the rotating handle 132 and the fixing handle 131 can clamp the ear contour, and the earphone 100 can be worn in an ear-clamping manner.
[0066] In the embodiments of this application, the bushing 122 and the rotating shaft 121 can rotate relative to each other around a third direction Z. One of the fixed handle 131 and the rotating handle 132 is connected to the bushing 122, and the other is connected to the rotating shaft 121, so that the rotating handle 132 can rotate relative to the fixed handle 131 around a third direction Z, so that the earphone 100 can switch between an in-ear mode and an ear clip mode, thereby enabling the earphone 100 to have both in-ear and ear clip wearing methods, improving the wearing flexibility of the earphone 100.
[0067] In this way, users can change the shape of the Headphone 100 according to their needs, so that the Headphone 100 can meet the usage needs of different scenarios, easily cope with different scenarios such as sports, commuting, meetings, and leisure, and the operation is simple, which improves the applicability of the Headphone 100.
[0068] For example, when users need to focus on listening to the audio playing in the headphones 100, they can adjust the headphones 100 to the first mode. In this mode, users can wear the headphones in an in-ear manner to obtain better sound quality and noise isolation.
[0069] In scenarios such as sports, travel, or communication with others, users can adjust the Earphone 100 to its second form. In this form, users can wear the Earphone 100 in a clip-on manner, allowing them to hear ambient sounds and improving safety to prevent accidents.
[0070] In some examples, the shaft 121 and the bushing 122 are interference-fitted to maintain the relative position of the rotating handle 132 and the fixed handle 131 by friction.
[0071] Understandably, the interference fit between the rotating shaft 121 and the bushing 122 can act as a damper, so that the damping structure 120 can impede the relative movement between the rotating handle 132 and the fixed handle 131.
[0072] For example, when an external force in the Z direction about a third direction is applied to at least one of the rotating handle 132 and the fixed handle 131, the rotating handle 132 and the fixed handle 131 can rotate relative to each other, thereby changing the included angle between the rotating handle 132 and the fixed handle 131, so that the earphone 100 can switch between an in-ear mode and an ear-clamping mode, and that the included angle between the rotating handle 132 and the fixed handle 131 is adjustable when the earphone 100 is in the ear-clamping mode.
[0073] When the external force in the Z direction around the third point stops acting on the earphone 100, the friction between the shaft 121 and the bushing 122 can maintain the relative position of the shaft 121 and the bushing 122, that is, maintain the relative position of the rotating handle 132 and the fixed handle 131, and the rotating handle 132 and the fixed handle 131 can remain relatively stationary under the action of friction.
[0074] This allows the rotating handle 132 to move to any position within its rotation range, enabling users to adjust the angle between the rotating handle 132 and the fixed handle 131 in the ear-clamping mode of the earphone 100 according to their own needs, thereby improving the applicability and wearing comfort of the earphone 100.
[0075] The rotating shaft 121 and the bushing 122 are set with an interference fit, and the friction between the two plays a damping role to maintain the relative position of the rotating handle 132 and the fixed handle 131. The structure is simple and helps to reduce the cost of the earphone 100.
[0076] For example, the rotation range of the rotating handle 132 relative to the fixed handle 131 can be 125°. That is, the maximum rotation angle of the rotating handle 132 relative to the fixed handle 131 can be 125°. At this time, when the earphone 100 is in the ear clip position, the minimum angle between the rotating handle 132 and the fixed handle 131 can be 55°.
[0077] This design avoids the minimum angle between the rotating handle 132 and the fixing handle 131 being too large or too small when the earphone 100 is in the ear-clamping mode, thus balancing the wearing comfort and wearing stability of the earphone 100.
[0078] Alternatively, when the earphone 100 is in the ear-clamping position, the minimum angle between the rotating handle 132 and the fixed handle 131 can be other angles, and the embodiments of this application do not further limit this.
[0079] In some examples, such as Figure 2 As shown, when the earphone 100 is in the ear-clamping position and the included angle between the rotating handle 132 and the fixed handle 131 is at its minimum value (e.g., 55°), the maximum distance between the rotating handle 132 and the fixed handle 131 is the first distance H1, and the value of the first distance H1 ranges from 3 mm to 6 mm.
[0080] For example, the average thickness of the human ear auricle is approximately 3mm to 6mm. Therefore, setting the first distance H1 to 3mm to 6mm avoids the earphone 100 being too tight when worn due to an excessively small first distance H1, and also avoids the earphone 100 being too loose when worn due to an excessively large first distance H1. In other words, setting the first distance H1 to 3mm to 6mm allows the earphone 100 to balance wearing comfort and secure fit.
[0081] For example, the value of the first distance H1 can be 4mm, 4.5mm, or 5mm, etc. The embodiments of this application do not further limit the value of the first distance H1.
[0082] In some examples, at least one of the hinge 121 and bushing 122 is made of metal. Understandably, metal has the property of high friction resistance, and setting at least one of the hinge 121 and bushing 122 to be made of metal can extend the service life of the earphone 100.
[0083] For example, when the material of the shaft 121 includes metal, the material of the shaft 121 may include copper, aluminum, stainless steel, silver, etc. When the material of the bushing 122 includes metal, the material of the bushing 122 may include copper, aluminum, stainless steel, silver, etc. The materials of the shaft 121 and the bushing 122 may be the same or different.
[0084] Understandably, at least one of the shaft 121 and bushing 122 may also be made of rubber to reduce the weight of the earphone 100 and lower its cost.
[0085] Figure 5 A schematic diagram of the headphone head and fixing handle provided for some embodiments of this application. Figure 6 The diagram shows the structure of the earphone head, fixing stem, and damping structure provided in some embodiments of this application. Figure 7 for Figure 6 A magnified view of a portion of region C1.
[0086] In some examples, such as Figure 5 As shown, a first through hole M1 is provided at the end of the fixing handle 131 away from the earphone head 110. The first through hole M1 penetrates the fixing handle 131 along the third direction Z (the thickness direction of the fixing handle 131). Figure 6 and Figure 7 As shown, the bushing 122 is embedded in the first through hole M1 and connected to the fixed handle 131. Along the third direction Z, at least one end of the rotating shaft 121 protrudes from the fixed handle 131 and is connected to the rotating handle 132.
[0087] This configuration allows the rotating handle 132 to rotate relative to the fixed handle 131 around a third direction Z, thereby enabling the earphone 100 to switch between in-ear and clip-on modes.
[0088] In some examples, such as Figure 6 As shown, along the third direction Z, the bushing 122 is located inside the first through hole M1. In this way, the influence of the bushing 122 on the rotation of the rotating handle 132 relative to the fixed handle 131 can be reduced.
[0089] Figure 8The diagram illustrates the structure of a damping structure provided in some embodiments of this application. In some examples, such as... Figure 8 As shown, the bushing 122 includes a bushing body 1221 and a limiting portion 1222. The bushing body 1221 extends circumferentially along the rotating shaft 121 and surrounds at least a portion of the rotating shaft 121. The bushing body 1221 and the rotating shaft 121 are rotatably connected, and the bushing body 1221 and the rotating shaft 121 are interference-fitted. The limiting portion 1222 is connected to the bushing body 1221.
[0090] Understandably, the end of the limiting part 1222 that is away from the bushing body 1221 extends away from the bushing body 1221.
[0091] In some examples, the bushing body 1221 and the limiting part 1222 are integrally formed. This configuration can improve the connection reliability between the bushing body 1221 and the limiting part 1222.
[0092] For example, a portion of the plate-like metal structure can be bent to form the connected bushing body 1221 and the limiting portion 1222. Figure 8 As shown, the bushing body 1221 can be an open structure, with the limiting part 1222 connected to one end of the opening of the bushing body 1221. Alternatively, the bushing body 1221 can also be a closed interface; the embodiments of this application do not further limit this.
[0093] like Figure 5 As shown, a limiting groove P1 is also provided at the end of the fixing handle 131 away from the earphone head 110, and the limiting groove P1 is connected to the first through hole M1. It can be understood that the limiting groove P1 can penetrate the fixing handle 131 along the third direction Z, or the limiting groove P1 can not penetrate the fixing handle 131 along the third direction Z.
[0094] like Figure 6 and Figure 7 As shown, the bushing body 1221 is embedded in the first through hole M1, and the limiting part 1222 is embedded in the limiting groove P1. The limiting groove P1 is used to limit the bushing 122 to rotate relative to the fixed handle 131 in the third direction Z.
[0095] Understandably, the bushing body 1221 is embedded in the first through hole M1 and connected to the fixed handle 131, and the limiting part 1222 is embedded in the limiting groove P1 and connected to the fixed handle 131. Along the second direction Y, the limiting part 1222 can contact the groove wall of the limiting groove P1, so that the limiting groove P1 can limit the limiting part 1222, thereby restricting the bushing 122 from rotating relative to the fixed handle 131 along the third direction Z, improving the connection reliability between the bushing 122 and the fixed handle 131.
[0096] In some examples, such as Figure 5As shown, the fixing handle 131 includes a fixed handle body 1311 and a protrusion 1312 connected to it. The protrusion 1312 is located on the side of the fixed handle body 1311 away from the earphone head 110. Understandably, the cross-sectional area of the protrusion 1312 is smaller than the cross-sectional area of the fixed handle body 1311, and the cross-section is the plane containing the second direction Y and the third direction Z. A first through hole M1 and a limiting groove P1 are formed on the protrusion 1312.
[0097] Figure 9 This is a schematic diagram of the structure of a rotating handle provided in some embodiments of this application. In some examples, such as... Figure 9 As shown, a groove P2 is provided at one end of the rotating handle 132, and a protrusion 1312 is embedded in the groove P2. At least one end of the rotating shaft 121 protrudes from the protrusion 1312 and is connected to the rotating handle 132, so that the rotating handle 132 can be connected to the rotating shaft 121.
[0098] Understandably, the protrusion 1312 embedded in the groove P2 can improve the structural regularity of the earphone 100 and allow the rotating handle 132 to cover the bushing 122, thereby improving the appearance of the earphone 100.
[0099] Continue to refer to Figure 9 In some examples, the rotating handle 132 includes a rotating handle body 1323, a first sub-part 1321, and a second sub-part 1322. The first sub-part 1321 and the second sub-part 1322 are disposed on one side of the rotating handle body 1323 along the extending direction of the rotating handle body 1323 and are connected to the rotating handle body 1323. For example, the rotating handle body 1323, the first sub-part 1321, and the second sub-part 1322 can be an integrally formed structure to improve the connection reliability of the three. The first sub-part 1321 and the second sub-part 1322 are disposed opposite each other along a third direction Z to form a groove P2.
[0100] For example, the surface of the first sub-part 1321 away from the second sub-part 1322 and the surface of the fixing handle body 1311 along the third direction Z can be smoothly connected, and the surface of the second sub-part 1322 away from the first sub-part 1321 and the surface of the fixing handle body 1311 along the third direction Z can be smoothly connected.
[0101] Continue to refer to Figure 9 In some examples, a second through hole M2 is provided on the first sub-part 1321, and the second through hole M2 penetrates the first sub-part 1321 along the third direction Z. A third through hole M3 is provided on the second sub-part 1322, and the third through hole M3 penetrates the second sub-part 1322 along the third direction Z. The second through hole M2 and the third through hole M3 are arranged opposite to each other in the third direction Z.
[0102] For example, one end of the rotating shaft 121 can be embedded in the second through hole M2, and the other end can be embedded in the third through hole M3, so that the rotating shaft 121 can be connected to the rotating handle 132.
[0103] Figure 10 This is a schematic diagram of the structure of a rotating shaft provided in some embodiments of this application. In some examples, such as... Figure 10 As shown, the second through hole M2 is a flat hole, and the end of the rotating shaft 121 near the second through hole M2 is the first flat part 1211, which is embedded in the second through hole M2; and / or, the third through hole M3 is a flat hole, and the end of the rotating shaft 121 near the third through hole M3 is the second flat part 1212, which is embedded in the third through hole M3.
[0104] Understandably, the first flat part 1211 is embedded in the second through hole M2. Through the cooperation between the flat hole and the flat part, the second through hole M2 can restrict the rotation of the shaft 121 relative to the rotating handle 132, thereby improving the connection reliability between the shaft 121 and the rotating handle 132.
[0105] The second flat part 1212 is embedded in the third through hole M3. Through the cooperation between the flat hole and the flat part, the third through hole M3 can restrict the rotation of the shaft 121 relative to the rotating handle 132, thereby improving the connection reliability between the shaft 121 and the rotating handle 132.
[0106] For example, such as Figure 10 As shown, the rotating shaft 121 may include a rotating shaft body 1213, a first flat portion 1211, and a second flat portion 1212. The first flat portion 1211 and the second flat portion 1212 are located on both sides of the rotating shaft body 1213 along a third direction Z and are respectively connected to the rotating shaft body 1213. The rotating shaft body 1213 may be a cylindrical or approximately cylindrical structure, and the bushing body 1221 surrounds the rotating shaft body 1213 and is connected to the rotating shaft body 1213.
[0107] For example, during the assembly of the earphone 100, the bushing 122 can be installed in the first through hole M1 and the limiting groove P1, so that the bushing 122 can be connected to the fixing handle 131. Then, the protrusion 1312 is installed in the groove P2, and then the rotating shaft 121 is passed through the second through hole M2, the bushing 122 and the third through hole M3, so that the rotating shaft 121 can be connected to the rotating handle 132.
[0108] Figure 11 This is an exploded structural diagram of a rotating handle provided in some embodiments of this application. In some examples, such as... Figure 11As shown, the rotating handle 132 may include a main body 132a and an outer part 132b. One end of the main body 132a is provided with a groove P2. The outer part 132b is connected to the main body 132a. The outer part 132b can cover the opening of the groove P2 along the third direction Z to improve the appearance of the earphone 100.
[0109] In other examples, the rotating handle 132 may also be an integral structure, and the embodiments of this application do not further limit this.
[0110] In some examples, such as Figure 2 As shown, the rotating handle 132 includes a first surface G1, which faces the fixed handle 131 when the earphone 100 is in the ear-clamping position. The first surface G1 includes a concave arc surface.
[0111] Understandably, providing a concave surface for the first surface G1 improves comfort and stability when wearing the headphones 100 in a clip-on manner. For example, the curvature of the concave surface can be adapted to the curvature of the ear.
[0112] Figure 12 This is a schematic diagram illustrating the structure of an earphone in an in-ear configuration, as provided in other embodiments of this application. In some examples, such as... Figure 12 As shown, the headphone head 110 includes a sound output plate 111 and a headphone head body 112. The headphone head body 112 is connected to the fixing handle 131, and the sound output plate 111 is connected to the headphone head body 112.
[0113] For example, the sound-emitting plate 111 can have a circular or elliptical outline to improve the wearing comfort of the headphones 100. For example, as... Figure 12 As shown, the height D1 of the sound output plate 111 along the first direction X can be 15.8 mm, and the width D2 of the sound output plate 111 along the second direction Y can be 13.2 mm. Alternatively, the height D1 of the sound output plate 111 along the first direction X and the width D2 along the second direction Y can also be other values, and the embodiments of this application do not limit them in this way.
[0114] A first speaker hole Q1 is provided on the sound output plate 111. The first speaker hole Q1 extends through the sound output plate 111 along the thickness direction of the sound output plate 111 and is located away from the headphone stem 130. For example, the speaker can be arranged adjacent to the first speaker hole Q1.
[0115] For example, the headphone head body 112 may have a second speaker hole Q2. There may be two second speaker holes Q2, and the two second speaker holes Q2 are set opposite each other along the third direction Z.
[0116] like Figure 1 and Figure 2As shown, along the direction from the headphone stem 130 to the headphone head 110 (first sub-direction X1), the sound output plate 111 gradually moves away from the fixed stem 131.
[0117] This reduces the distance between the first speaker hole Q1 and the ear canal when the earphone 100 is worn in a clip-on style, improving the sound quality of the earphone 100 while maintaining the same performance when worn in an in-ear style.
[0118] For example, such as Figure 1 and Figure 2 As shown, the side where the sound output plate 111 and the earphone head body 112 are connected has an angle α with the first direction X, and the value of the angle α is in the range of 10° to 15°. For example, the value of the angle α can be 11°, 12° or 13°, etc., and the embodiments of this application do not further limit the value of the angle α.
[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
