[0029] The present application provides an earphone, which includes a speaker assembly according to any of the above embodiments and a wearing assembly connected to the speaker assembly, wherein the wearing assembly is used to position the speaker assembly in the facial area in front of the user's tragus when worn.

[0030] The beneficial effects of this application are as follows: through the above-mentioned method, the auxiliary face-sticking assembly serves as an auxiliary support. When worn, the auxiliary face-sticking assembly contacts the facial area in front of the user's tragus, thereby providing auxiliary support for the bone conduction speaker along the direction of bone conduction vibration. This effectively alleviates the supporting pressure of the vibration plate on the face along its vibration direction, thereby effectively reducing the workload of the transducer device, thereby effectively improving the sound quality of the bone conduction speaker, and thus effectively improving the sound quality of the headphones. Furthermore, when observed along the direction of bone conduction vibration, the auxiliary face-sticking assembly surrounds the periphery of the vibration plate along the circumference of the vibration plate. Based on this, the periphery of the vibration plate can all receive auxiliary support from the auxiliary face-sticking assembly, thereby effectively improving the auxiliary face-sticking assembly's positioning effect on the vibration plate. Furthermore, when observing along the vibration direction of the vibration plate, the width of the auxiliary face-sticking component facing the tragus (wherein the width of the auxiliary face-sticking component facing the tragus is equal to the width of the hard support member facing the tragus as described above) is smaller than the width away from the tragus (wherein the width of the auxiliary face-sticking component away from the tragus is equal to the width of the hard support member away from the tragus as described above). Based on this, the vibration plate as a whole can be closer to the user's tragus, thereby effectively improving the sound transmission effect of the bone conduction speaker, so as to effectively improve the sound quality of the bone conduction speaker, and further effectively improve the sound quality of the earphones. Furthermore, the auxiliary face-sticking component includes a hard support member for rigid support, and also includes a soft fitting member for flexible contact with the user's face. When in the wearing state, the auxiliary face-sticking component is in soft contact with the facial area in front of the user's tragus through the soft fitting member, while providing rigid support through the hard support member. This can effectively ensure the supporting capacity of the auxiliary face-sticking component while effectively improving the softness of the auxiliary face-sticking component, thereby effectively improving the wearing comfort of the earphones. The rigid support member is closed around the periphery of the vibration plate along the circumference of the vibration plate, so that the auxiliary face-sticking assembly is entirely arranged around the periphery of the vibration plate, thereby providing auxiliary support to the periphery of the vibration plate, thereby effectively improving the positioning effect of the auxiliary face-sticking assembly on the vibration plate. In addition, the width of the rigid support member facing the tragus is smaller than the width facing away from the tragus, so that the width of the auxiliary face-sticking assembly facing the tragus is smaller than the width facing away from the tragus, thereby bringing the entire vibration plate closer to the user's tragus, effectively improving the sound transmission effect of the bone conduction speaker, and thus effectively improving the sound quality of the headphones.Furthermore, a notch is provided on the side of the soft fitting facing the tragus. On the one hand, the notch does not affect the position of the vibration plate on the side of the soft fitting. Due to the presence of the notch, the vibration plate can be closer to the user's tragus and ear canal, which makes the vibration transmission efficiency of the vibration plate higher. On the other hand, since the width of the hard support member close to the tragus is smaller, the supporting effect of the hard support member on the soft fitting member in this area is smaller. Therefore, providing a notch on the side of the soft fitting member facing the tragus can effectively prevent the soft fitting member from being deformed or damaged on the side facing the tragus, thereby affecting the use of the earphones.

[0031] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application.

It is understandable that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0058] The terms "first," "second," and the like in this application are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0059] The following earphone embodiment of the present application describes an exemplary structure of the earphone 1.

[0060] As shown in Figure 1, the headset 1 may include a wearing assembly 2, a speaker assembly 3, and a stick microphone assembly 7. There may be two speaker assemblies 3. The two speaker assemblies 3 are respectively configured to transmit vibration and / or sound to the user's left and right ears. The two speaker assemblies 3 may be identical or different. For example, one speaker assembly 3 may be provided with a stick microphone assembly 7, while the other speaker assembly 3 may not be provided with a stick microphone assembly 7.

[0061] As shown in Figure 2, the wearing assembly 2 may include a headband assembly 21, a telescopic assembly 22, and a torsion assembly 23. There may be two telescopic assemblies 22, and two torsion assemblies 23. The two ends of the headband assembly 21 are connected to two telescopic assemblies 22 in a one-to-one correspondence, and the two telescopic assemblies 22 are connected to two torsion assemblies 23 in a one-to-one correspondence. The two torsion assemblies 23 are connected to two speaker assemblies 3 in a one-to-one correspondence. The headband assembly 21 is used to pass over the top of the user's head. The shape of the headband assembly 21 can match the user's head contour, making the user more comfortable and stable when wearing the headband assembly 21. The headband assembly 21 is also used to elastically clamp the two sides of the user's head. The telescopic assembly 22 can perform telescopic movement to change its own length, thereby changing the distance between the headband assembly 21 and the speaker assembly 3. This can be adaptively adjusted according to the user's head shape to position the speaker assembly 3 in the appropriate position, thereby improving the compatibility of the wearing assembly 2. The torsion component 23 can generate elastic torsion, and can generate torsion as the speaker component 3 contacts the user's head in the wearing state, so that the speaker component 3 can better fit the user's face or be positioned on the ear.

[0062] As shown in Figure 2, the headband assembly 21 may include a clamping assembly 210 and a first elastic covering body 212. The clamping assembly 210 may include an elastic sheet to realize an elastic clamping function. The first elastic covering body 212 may include a covering body 2121 and an elastic band 2122 integrally formed with the covering body 2121.

The elastic band 2122 is separated from the covering body 2121 between the two ends of the elastic band 2122 and the connection position of the covering body 2121. The elastic band 2122 is used to assist in positioning the clamping assembly 210 on the user's head when worn.

[0063] As shown in FIG2 , the telescopic assembly 22 may include a fixed portion 221 and a telescopic portion 223 that is telescopically arranged relative to the fixed portion 221. The two ends of the clamping assembly 210 are respectively fixed to the corresponding fixed portion 221, for example, by plugging. The telescopic assembly 22 may include a decorative portion 224. The fixed portion 221 is provided with a slide groove 2203, and the telescopic portion 223 is slidably arranged within the slide groove 2203.

When the earphone 1 is worn on the user's head, the wearing assembly 2 can position the speaker assembly 3 in the facial area in front of the user's tragus.

[0066] As shown in Figure 2, the housing assembly 30 may include a main shell 31 and a main cover 32. The main shell 31 may have an open end, and the main cover 32 covers the open end of the main shell 31. The main cover 32 may be provided with a sound outlet (not marked) for the air conduction speaker 50 to emit sound.

Alternatively, the number of control circuit boards 62 may be two, and each speaker assembly 3 may include a control circuit board 62 respectively. There may also be two batteries 61, and each speaker assembly 3 may include a battery 61 respectively.

[0068] The stick microphone assembly 7 is rotatably mounted on the speaker assembly 3. The stick microphone assembly 7 includes a stick body assembly 70, a microphone assembly 80, and a hinge mechanism 91. The microphone assembly 80 and the hinge mechanism 91 are connected to both ends of the stick body assembly 70, and the hinge mechanism 91 is rotatably connected to the speaker assembly 3. When worn, the hinge mechanism 91 can be rotated relative to the speaker assembly 3 to position the microphone assembly 80 within the sound pickup area of ​​the user's mouth. The microphone assembly 80 is equipped with at least one microphone and an associated button that turns the microphone on and off.

[0069] In fields like medicine and anatomy, the human body is defined as having three fundamental planes: the sagittal plane, the coronal plane, and the horizontal plane, as well as three fundamental axes: the sagittal axis (SA), the coronal axis (CA), and the vertical axis (VA). The sagittal plane is a plane perpendicular to the ground, drawn along the anterior-posterior axis of the body, dividing the body into left and right halves. The coronal plane is a plane perpendicular to the ground, drawn along the lateral-lateral axis of the body, dividing the body into anterior-posterior halves. The horizontal plane is a plane parallel to the ground, drawn along the lateral-lateral axis of the body, dividing the body into upper and lower halves. Accordingly, the sagittal axis (SA) is the axis along the lateral-lateral axis of the body and perpendicular to the coronal plane; the coronal axis is the axis along the lateral-lateral axis of the body and perpendicular to the sagittal plane; and the vertical axis (VA) is the axis along the lateral-lateral axis of the body and perpendicular to the horizontal plane. As shown in FIG3 , when the earphone 1 is worn, the wearing component 2 is clamped on both sides of the user's head, and the speaker component 3 is located in the facial area in front of the tragus along the sagittal axis SA.

[0070] The following content will provide a detailed description of the earphone 1 or some of the components and structures mentioned above. Of course, some of the structures and components mentioned above, such as the bone conduction speaker 40, the air conduction speaker 50, etc., can be used not only in the earphone 1, but also in other electronic devices, such as mobile phones, speakers, smart wearable devices, etc.

[0071] The following content mainly describes the structure of the speaker component 3 and other parts of the earphone 1 by way of example.

[0072] Optionally, as shown in Figures 2, 4, and 5, in some embodiments, the speaker assembly 3 may include: a housing assembly 30 and a bone conduction speaker 40. Further referring to Figures 6, 7, and 8, the bone conduction speaker 40 includes a core housing 41, a transducer 42, a vibration-transmitting face-attaching assembly 43, and an auxiliary face-attaching assembly 44.

The vibration-transmitting face-attaching assembly 43 includes a vibration plate 431, which is connected to the transducer 42 and directly or indirectly contacts the facial area in front of the user's tragus when worn. In an indirect contact embodiment, the auxiliary face-fitting component 44 includes a hard support part 441 and a soft fitting part 442. The hard support part 441 is connected to the movement housing 41. When observed along the vibration direction of the vibration plate 431, the hard support part 441 is closed along the circumference of the vibration plate 431 and surrounds the periphery of the vibration plate 431. The width WY1 of the hard support part 441 facing the tragus is smaller than the width WY2 on the side away from the tragus. The soft fitting part 442 is arranged on the hard support part 441. The soft fitting part 442 is provided with a notch 443 on the side facing the tragus, and surrounds the vibration plate 431 along the circumferential portion of the vibration plate 431. The soft fitting part 442 is used to contact the facial area outside the vibration plate 431 when worn.

[0073] Specifically, the bone conduction speaker 40 transmits sound to the user through bone conduction vibration. Among them, the transducer 42 is a device that converts electrical signals into vibrations, which is connected to the vibration plate 431 and drives the vibration plate 431 to vibrate based on the corresponding electrical signal. The vibration direction of the vibration plate 431 is also called the bone conduction vibration direction z1, that is, the vibration direction of the bone conduction speaker 40, wherein the bone conduction vibration direction z1 is roughly parallel to the coronal axis of the human body when in the wearing state. Among them, the vibration plate 431 is the main component of the vibration face-mounted component 43. When the earphone 1 is in the wearing state, the vibration plate 431 is in direct or indirect contact with the facial area in front of the user's tragus. Driven by the transducer 42, the vibration plate 431 transmits sound to the user in the form of bone conduction vibration.

[0074] Furthermore, the auxiliary face-sticking assembly 44 provides auxiliary support. When worn, it contacts the user's facial area in front of the tragus, providing auxiliary support for the bone conduction speaker 40 along the bone conduction vibration direction z1. This effectively alleviates the pressure exerted by the vibration plate 431 on the face along its vibration direction, thereby effectively reducing the workload of the transducer 42, thereby effectively improving the sound quality of the bone conduction speaker 40 and, by extension, the earphone 1. Furthermore, when viewed along the bone conduction vibration direction z1, the auxiliary face-sticking assembly 44 surrounds the periphery of the vibration plate 431 along its circumference. This ensures that the periphery of the vibration plate 431 receives auxiliary support from the auxiliary face-sticking assembly 44, effectively improving the positioning of the vibration plate 431 by the auxiliary face-sticking assembly 44.

[0075] Furthermore, when observed along the vibration direction of the vibration plate 431, the width of the auxiliary face-sticking component 44 toward the tragus (wherein, the width of the auxiliary face-sticking component 44 toward the tragus is equal to the width WY1 of the hard support component 441 toward the tragus as described above) is smaller than the width away from the tragus (wherein, the width of the auxiliary face-sticking component 44 away from the tragus is equal to the width WY2 of the hard support component 441 away from the tragus as described above). Based on this, the vibration plate 431 as a whole can be closer to the user's tragus, thereby effectively improving the sound transmission effect of the bone conduction speaker 40, thereby effectively improving the sound quality of the bone conduction speaker 40, and then effectively improving the sound quality of the earphone 1.

[0076] Furthermore, the auxiliary face-fitting assembly 44 includes a hard support member 441 for rigid support, and a soft fitting member 442 for flexible contact with the user's face. When worn, the auxiliary face-fitting assembly 44 provides soft contact with the user's facial area in front of the tragus through the soft fitting member, while providing rigid support through the hard support member 441. This effectively ensures the support capacity of the auxiliary face-fitting assembly 44 while effectively improving the softness of the auxiliary face-fitting assembly 44, thereby effectively improving the wearing comfort of the earphone 1. The hard support member 441 is closed around the periphery of the vibration plate 431 along the circumference of the vibration plate 431, so that the auxiliary face-fitting assembly 44 is entirely arranged around the periphery of the vibration plate 431, so that the periphery of the vibration plate 431 can all receive auxiliary support from the auxiliary face-fitting assembly 44, thereby effectively improving the positioning effect of the auxiliary face-fitting assembly 44 on the vibration plate 431. In addition, the width WY1 of the hard support member 441 toward the tragus is smaller than the width WY2 away from the tragus, so that the width of the auxiliary face-sticking component 44 toward the tragus is smaller than the width away from the tragus, so that the vibration plate 431 as a whole can be closer to the user's tragus, thereby effectively improving the sound transmission effect of the bone conduction speaker 40, and thereby effectively improving the sound quality of the earphone 1.

[0077] Furthermore, a notch 443 is provided on the side of the soft fitting 442 facing the tragus. On the one hand, the notch 443 does not affect the position of the vibration plate 431 on the side of the soft fitting 442. Due to the presence of the notch 443, the vibration plate 431 can be closer to the user's tragus and ear canal, so that the vibration transmission efficiency of the vibration plate 431 is higher. On the other hand, since the width of the hard support component 441 close to the tragus is smaller, the supporting effect of the hard support component 441 on the soft fitting 442 in this area is smaller. Therefore, the notch 443 on the side of the soft fitting 442 facing the tragus can effectively prevent the soft fitting 442 from being deformed or damaged on the side facing the tragus, thereby affecting the use of the earphone 1.

[0078] Optionally, in some embodiments, the material of the soft fitting member 442 may include a softer material such as sponge.

[0079] Optionally, as shown in Figures 7 and 9, in some embodiments, the ratio of the width WY1 of the hard support member 441 facing the tragus to the width WY2 of the hard support member 441 facing away from the tragus is less than or equal to 0.2. If this ratio is too large, the distance between the vibration plate 431 and the tragus will increase, affecting the sound transmission effect of the bone conduction speaker 40. If the ratio is too small, the structural strength of the auxiliary face-mounted assembly 44 will be reduced, thereby reducing the auxiliary support capacity of the auxiliary face-mounted assembly 44. Therefore, setting the above ratio to, for example, 0.1, 0.15, or 0.2 ensures that the auxiliary face-mounted assembly 44 has stable auxiliary support capacity while ensuring that the vibration plate 431 is sufficiently close to the tragus to effectively improve the sound transmission effect of the bone conduction speaker 40, thereby effectively improving the sound quality of the bone conduction speaker 40.

[0080] Optionally, in some embodiments, the rigid support member 441 is made of plastic, and the width WY1 on the side facing the tragus is between 0.5 mm and 1.5 mm. Specifically, the rigid support member 441 is made of plastic. This effectively ensures the structural strength of the rigid support member 441 while also effectively reducing the mass of the rigid support member 441, thereby effectively reducing the overall mass of the bone conduction speaker 40. Furthermore, if the width WY1 of the hard support member 441 on the side facing the tragus is too large, the distance between the vibration plate 431 and the tragus will increase, affecting the sound transmission effect of the bone conduction speaker 40. If it is too small, the structural strength of the auxiliary face-attaching assembly 44 will be reduced, thereby reducing the auxiliary support capacity of the auxiliary face-attaching assembly 44. Therefore, based on the above-mentioned material, the width WY1 of the hard support member 441 on the side facing the tragus is set between 0.1mm and 2mm. Based on this, the vibration plate 431 can be placed as close to the tragus as possible, while also effectively ensuring the structural strength of the hard support member 441 and the connection strength between the hard support member 441 and the movement housing 41. In some embodiments, the hard support member 441 can also be made of materials such as resin, carbon fiber, or metal. For example, in some embodiments, the width WY1 of the hard support member 441 facing the tragus is set to 0.7, 0.8, or 0.9 mm, and the width WY2 of the hard support member 441 facing away from the tragus is set to 10.75 mm ± 0.1 mm. For another example, in some embodiments, the width WY1 of the hard support member 441 facing the tragus is set to 0.84 mm, and the width WY2 of the hard support member 441 facing away from the tragus is set to 9.8 mm.

[0081] Optionally, as shown in Figures 7 and 10, in some embodiments, the hard support member 441 is detachably connected to the movement shell 41. Based on this, when the hard support member 441, which is a vulnerable component, is damaged, it can be removed from the movement shell 41 and replaced, thereby not affecting the continued use of the earphone 1, thereby effectively improving the service life of the earphone 1.

[0082] Optionally, as shown in Figures 7 and 10, in some embodiments, the hard support member 441 includes a support plate 444 and an annular flange 445, the support plate 444 is provided with a through hole 440, the vibration plate 431 is exposed through the through hole 440, the annular flange 445 is provided on the side of the support plate 444 facing the movement housing, and surrounds the periphery of the through hole 440, the annular flange 445 is sleeved on the periphery of the movement housing 41, and the outer wall surface of the movement housing 41 and the inner wall surface of the annular flange 445 are respectively provided with mutually cooperating snap-fit ​​structures 40a and 40b, specifically the snap-fit ​​structure 40a provided on the outer wall surface of the movement housing 41 and the snap-fit ​​structure 40b provided on the inner wall surface of the annular flange 445.

[0083] Specifically, the central axis of the through hole 440 is set closer to the tragus than the central axis of the support plate 444. Based on this, the width WY1 of the hard support member 441 facing the tragus is smaller than the width WY2 on the side away from the tragus, so that the vibration plate 431 as a whole can be closer to the user's tragus, thereby effectively improving the sound transmission effect of the bone conduction speaker 40, and then effectively improving the sound quality of the bone conduction speaker 40. Furthermore, an annular flange 445 is arranged on the side of the support plate 444 facing the movement shell 41 and surrounds the periphery of the through hole 440. In this way, on the basis of the support plate 444, the annular flange 445 increases the height and enhances the structural strength to facilitate the setting of the snap structure 40b, and by the annular flange 445 being sleeved on the periphery of the movement shell 41, the connection between the snap structure 40b and the snap structure 40a of the movement shell 41 can be made more stable and reliable, and the detachable connection through the snap method can also effectively simplify the assembly steps of the hard support part 441 and the movement shell 41, thereby effectively improving the assembly efficiency of the hard support part 441 and the movement shell 41.

[0084] Alternatively, in one embodiment, the rigid support member 441 may be an integrally formed component, wherein the side of the support member facing the movement housing 41 protrudes and extends around the through hole 440 along the bone conduction vibration direction z1 to form the annular flange 445 described above. Alternatively, in other embodiments, the rigid support member 441 may be formed by other means, such as by connecting the support plate 444 and the annular flange 445 by welding, bonding, or the like to form the rigid support member 441.

[0085] Optionally, as shown in Figures 7-8, in some embodiments, the bone conduction speaker 40 also includes a first vibration plate 45, the transducer device 42 is elastically suspended in the movement housing 41 through the first vibration plate 45, the vibration plate 431 is independent of the movement housing 41, and the vibration face-attaching component 43 also includes a soft vibration member 432, which is attached to the side of the vibration plate 431 facing the facial area. The hardness of the soft vibration member 432 is greater than the hardness of the soft fitting member 442, and in the free state, the side of the soft fitting member 442 facing the facial area protrudes beyond the side of the soft vibration member 432 facing the facial area.

[0086] Specifically, the first vibration transmission piece 45 is a component with a certain degree of elasticity. The transducer 42 is elastically suspended within the movement housing 41 via the first vibration transmission piece 45, while the vibration plate 431 is independent of the movement housing 41. Based on this, the first vibration transmission piece 45 can not only effectively connect the transducer 42 and the vibration transmission face assembly 43 to the movement housing 41, but also effectively reduce the vibration transmitted from the transducer 42 to the movement housing 41, thereby effectively improving the sound quality of the bone conduction speaker 40. Among them, the vibration-transmitting face-attaching component 43 also includes a soft vibration-transmitting part 432 attached to the side of the vibration plate 431 facing the facial area. Driven by the transducer device 42, the vibration plate 431 further drives the soft vibration-transmitting part 432 to vibrate. The vibration plate 431 indirectly contacts the facial area in front of the auricle through the soft vibration-transmitting component and transmits the sound to the user through bone conduction vibration. In other words, the soft vibration-transmitting component contacts the facial area in front of the auricle and transmits the sound to the user through bone conduction vibration. Based on this, the comfort of the bone conduction speaker 40 when transmitting sound to the user through bone conduction vibration can be effectively improved.

[0087] Furthermore, the soft vibration transmitter 432 and the soft fitting member 442 are parts that come into contact with the user's face. If the hardness of the soft fitting member 442 is set too large or greater than that of the soft vibration transmitter 432, it will to a certain extent hinder the soft vibration transmitter 432 from transmitting vibrations to the facial area in front of the user's tragus. Therefore, setting the hardness of the soft vibration transmitter 432 to be greater than the hardness of the soft fitting member 442 can effectively reduce the vibration transmission obstruction of the soft fitting member 442 to the soft vibration transmitter 432, thereby effectively improving the vibration transmission efficiency of the soft vibration transmitter 432. Furthermore, the hardness of the soft fitting part 442 is less than that of the soft vibration transmitting part 432, so the soft fitting part 442 is more easily deformed than the soft vibration transmitting part 432. Therefore, in the free state (when the earphone 1 is not worn), by protruding the side of the soft fitting part 442 facing the face area beyond the side of the soft vibration transmitting part 432 facing the face area, the soft fitting part 442 can be provided with a larger deformation space along the bone conduction vibration direction z1. Since the soft fitting part 442 is softer than the soft vibration transmitting part 432, the larger deformation space can make the side of the soft fitting part 442 facing the face area and the side of the soft vibration transmitting part 432 facing the face area flush with the face when the earphone 1 is in the wearing state, while also ensuring that the auxiliary face-fitting component 44 has a sufficiently large auxiliary supporting force, thereby effectively alleviating the supporting pressure of the vibration plate 431 along its vibration direction, and then effectively reducing the workload of the transducer 42, so as to effectively improve the sound quality of the bone conduction speaker 40.

[0088] Optionally, in some embodiments, in the free state, the side of the soft fitting 442 facing the face area and the side of the soft vibration transmitter 432 facing the face area can also be set to a flush structure, wherein along the bone conduction vibration direction z1, the soft vibration transmitter 432 is provided with a preset distance that can move relative to the soft fitting 442 along the bone conduction vibration direction z1 when in the worn state. By setting a preset distance for the soft vibration transmitter 432, a larger deformation space is provided for the soft fitting 442 along the bone conduction vibration direction z1, so that when the earphone 1 is in the worn state, the side of the soft fitting 442 facing the face area and the side of the soft vibration transmitter 432 facing the face area are flush with the face, while also ensuring that the auxiliary face-fitting component 44 has a sufficiently large auxiliary supporting force, thereby effectively alleviating the supporting pressure of the vibration plate 431 along its vibration direction, and thereby effectively reducing the workload of the transducer device 42, so as to effectively improve the sound quality of the bone conduction speaker 40.

[0089] Optionally, in some embodiments, the material of the soft vibration transmitting member 432 may be silicone. In other embodiments, the soft vibration transmitting member 432 may also be made of materials such as rubber, TPU or TPE.

[0090] Optionally, referring to Figures 6, 8 and 11, in some embodiments, the movement housing 41 is provided with a receiving space 410 with an open end (in some embodiments herein, the receiving space 410 is also referred to as a second receiving space), and the transducer 42 is disposed in the receiving space 410. The vibration face-attaching assembly 43 includes a vibration plate 431, a soft vibration transmitting member 432 and a hard bracket 433, wherein the middle area 432a of the soft vibration transmitting member 432 is fixed to the vibration plate 431 in a molding manner, and the edge area 432b of the soft vibration transmitting member 432 is fixed to the hard bracket 433 in a molding manner, the vibration plate 431 is assembled and fixed to the transducer 42, and the hard bracket 433 is assembled and fixed to the movement housing 41, and the soft vibration transmitting member 432 covers the open end 413 of the movement housing 41 and is used to contact human skin.

[0091] Specifically, the soft vibration transmitter 432 is used to contact human skin. That is, as described above, the soft vibration transmitter 432 contacts the facial area in front of the tragus and transmits sound to the user through bone conduction vibration. This effectively improves the comfort of the bone conduction speaker 40 when transmitting sound to the user through bone conduction vibration. The edge region 432b of the soft vibration transmitter 432 and the hard support 433 are fixed to the hard support 433 through molding, and the middle region 432a of the soft vibration transmitter 432 is also fixed to the vibration plate 431 through molding. This effectively simplifies the assembly process of the vibration transmitter face-mounted assembly 43, effectively improving the assembly efficiency of the speaker assembly 3, and effectively improving the structural stability of the soft vibration transmitter 432, thereby effectively improving the operating stability of the bone conduction speaker 40. The edge region 432b of the soft vibration transmitting member 432 and the hard support 433 are fixed to the hard support 433 by molding, and the middle region 432a of the soft vibration transmitting member 432 is fixed to the vibration plate 431 by molding. The molding method may include injection molding, molding, etc. For example, the soft vibration transmitter 432 can be made by an injection molding process, and during the injection molding process of the soft vibration transmitter 432, the vibration plate 431 and the hard bracket 433 are placed in the soft vibration transmitter 432 manufacturing mold. When the molding material is injected into the soft vibration transmitter 432 manufacturing mold, the molding material forms a liquid soft vibration transmitter 432 of corresponding shape structure under the constraint of the manufacturing mold and is respectively bonded to the corresponding parts of the vibration plate 431 and the hard bracket 433. After the liquid soft vibration transmitter 432 is cooled and solidified, the soft vibration transmitter 432 is formed, and the soft vibration transmitter 432 is respectively connected to the vibration plate 431 and the hard bracket 433. Based on this, the assembly process of the vibration face assembly 43 can be effectively simplified, the assembly efficiency of the speaker assembly 3 can be effectively improved, and the structural stability of the soft vibration transmitter 432 can be effectively improved, thereby effectively improving the working stability of the bone conduction speaker 40. Among them, this article involves a similar description of the fixed molding method, and its principle is as described above, so this article will not elaborate on it in detail.

[0092] Furthermore, while the hard bracket 433 is connected to the soft vibration transmitter 432, it is also assembled and fixed to the movement housing 41. Based on this, the fixing effect and installation structure strength of the vibration transmitter face-mounted component 43 can be effectively improved, thereby effectively preventing the vibration transmitter face-mounted component 43 from vibrating in the bone conduction vibration direction z1 when the transducer device 42 drives the vibration transmitter face-mounted component 43 to vibrate, and the vibration direction of the vibration transmitter face-mounted component 43 is offset, which affects the bone conduction sound transmission, thereby effectively improving the sound quality of the bone conduction speaker 40.

[0093] Optionally, further referring to Figures 11 and 12 , in some embodiments, a plurality of embedding grooves 434 are provided on the side of the vibration plate 431 facing the soft vibration transmitting member 432, and the soft vibration transmitting member 432 is embedded in the plurality of embedding grooves 434 in a molded manner. Specifically, the plurality of embedding grooves 434 are provided on the side of the vibration plate facing the soft vibration transmitting member 432, and the soft vibration transmitting member 432 is embedded in the plurality of embedding grooves 434 in a molded manner, thereby effectively improving the connection stability between the vibration plate 431 and the soft vibration transmitting member 432.

[0094] Optionally, as shown in FIG12 , in some embodiments, when viewed along the vibration direction of the vibration plate 431, the plurality of beaded grooves 434 are located near the edge of the vibration plate 431 and are spaced apart around the central axis z3 of the vibration plate 431. Specifically, the plurality of beaded grooves 434 are spaced apart around the central axis z3 of the vibration plate 431 at the edge of the vibration plate 431, thereby further improving the connection stability between the vibration plate 431 and the soft vibration transmission member 432.

[0095] Optionally, as shown in Figures 11-12, in some embodiments, the embedding groove 434 is configured to connect the side of the vibration plate 431 facing the soft vibration transmitter 432 and the side away from the soft vibration transmitter 432, wherein the soft vibration transmitter 432 is embedded in the embedding groove 434 in a molding manner and is clamped with the side of the vibration plate 431 away from the soft vibration transmitter 432, based on which the connection stability between the vibration plate 431 and the soft vibration transmitter 432 can be further improved.

[0096] Optionally, further referring to Figures 11 and 13 , in some embodiments, the rigid support 433 is arranged in an annular shape, with the axial direction of the rigid support 433 being arranged along the vibration direction of the vibration plate 431. The rigid support 433 is connected to the core housing 41 along the axial direction z4 and is sleeved on the core housing 41. Specifically, the rigid support 433 is arranged in an annular structure, with the axial direction z4 being parallel to the bone conduction vibration direction z1. The rigid support 433 is connected to the core housing 41 along the axial direction and is sleeved on the core housing 41. This effectively simplifies the assembly process between the rigid support 433 and the core housing 41, thereby effectively improving the assembly efficiency of the bone conduction speaker 40.

[0097] Optionally, as shown in Figure 13, in some embodiments, the radial thickness Hd1 of the hard bracket 433 is less than the axial height Ht1 of the hard bracket 433. Based on this, the connection stability between the hard bracket 433 and the movement shell 41 can be effectively improved, while the interference caused by the hard bracket 433 to the components arranged around it can also be effectively reduced.

[0098] Alternatively, for example, in some embodiments, the radial thickness Hd1 of the rigid support 433 is set to 0.15-0.25 mm, such as 0.16 mm or 0.2 mm, and the thickness of the edge region of the soft vibration transmitter 432, such as the portion indicated by the arrow 432b, is set to 0.12-0.18 mm, such as 0.13 mm or 0.15 mm. For another example, in some embodiments, the thickness Hd2 of the bend of the rigid support 433 is 0.2-0.4 mm, such as 0.25 mm or 0.3 mm, and the thickness Hd3 of the middle portion is 0.15-0.2 mm, such as 0.16 mm or 0.17 mm. The thickness of the middle region 432a of the soft vibration transmitter 432 is 0.3-0.6 mm, such as 0.4 mm, and the thickness of the edge region 432b is 0.4-0.6 mm, such as 0.58 mm.

[0099] Optionally, as shown in Figures 11 and 13, in some embodiments, the edge region 432b of the soft vibration transmitter 432 is fixed to the inner annular surface 433a or the outer annular surface 433b of the rigid support 433 by molding. Specifically, the edge region 432b of the soft vibration transmitter 432 can be fixed to the inner annular surface 433a or the outer annular surface 433b of the rigid support 433 by molding. Based on this surface connection between the soft vibration transmitter 432 and the rigid support 433, the connection stability between the soft vibration transmitter 432 and the rigid support 433 can be effectively improved.

[0100] Optionally, as shown in Figures 7, 11 and 14, in some embodiments, an annular groove 4103 is provided on the end face of the open end 413 of the movement shell 41, so that an inner shell 4121 and an outer shell 4122 separated by the annular groove 4103 and nested with each other are formed at the end of the movement shell 41, and the hard bracket 433 is embedded in the annular groove 4103 and is sleeved on the periphery of the inner shell 4121.

[0101] Specifically, the rigid bracket 433 is embedded in the annular groove 4103 and sleeved around the periphery of the inner housing 4121. This allows the rigid bracket 433 to be connected to the core housing 41 while also effectively concealing a portion of the rigid bracket 433 within the annular groove 4103, thereby enhancing the aesthetics of the bone conduction speaker 40. In this embodiment, the core housing 41 is a one-piece molded component. The inner housing 4121 and outer housing 4122 can be understood as nested housing portions formed by separating the ends of the core housing 41 by the annular groove 4103. The outer housing 4122 sleeves around the periphery of the inner housing 4121. Optionally, in other embodiments, the movement housing 41 can also be assembled from an inner housing 4121 and an outer housing 4122, wherein the inner housing 4121 is a housing member provided with a accommodating space 410 for accommodating the transducer device 42, and the outer housing 4122 is a housing member used to surround the outer periphery of the inner housing 4121 to form an annular groove 4103.

[0102] Optionally, as shown in Figures 7, 11 and 14, in some embodiments, the soft vibration transmitter 432 is fixed to a portion of the outer annular surface 433b of the hard bracket 433 and abuts the movement housing 41, and the hard bracket 433 is embedded in the annular groove 4103 relative to the exposed portion of the soft vibration transmitter 432.

[0103] Specifically, the edge area 432b of the soft vibration transmitter 432 is set to be an arc shape, wherein the edge area 432b of the soft vibration transmitter 432 is fitted with the partial outer ring surface 433b of the hard bracket 433 so that the soft vibration transmitter 432 is fixed as a whole to the partial outer ring surface 433b of the hard bracket 433, and the soft vibration transmitter 432 is in contact with the outer shell 4122 of the movement shell 41, and the hard bracket 433 is embedded in the annular groove 4103 relative to the exposed part of the soft vibration transmitter 432. Based on this, the hard bracket 433 can be effectively and completely hidden, thereby effectively improving the aesthetics of the bone conduction speaker 40.

[0104] Optionally, as shown in FIG11 , in some embodiments, the transducer device 42 includes a magnetic circuit system 426 elastically suspended within the movement housing 41, and the rigid support 433 is a non-magnetic metal support, such as a stainless steel support. Specifically, the transducer device 42 includes the magnetic circuit system 426, which is a system of magnetic components elastically suspended within the accommodating space 410. For example, in the above-described embodiment, the magnetic circuit system 426 is elastically suspended within the accommodating space 410 via a first vibration transmission member. The rigid support 433 is connected to the movement housing 41 in the above-described manner. The non-magnetic metal support 433 effectively reduces interference with the magnetic circuit system 426, thereby effectively improving the vibration stability of the transducer device 42-driven vibration of the vibration plate 431 and, consequently, the sound quality of the bone conduction speaker 40. In other embodiments, the rigid support 433 may also be made of other materials, such as brass.

[0105] Alternatively, referring to Figures 6 and 7, and further referring to Figures 15 and 16, in some embodiments, as described above, the housing assembly 30 includes a main housing 31, wherein the main housing 31 includes a bottom wall 311 and a peripheral side wall 312 connected to the bottom wall 311 (wherein the peripheral side wall 312 is also referred to as a first peripheral side wall in some embodiments of this document, and the bottom wall 311 is also referred to as a first bottom wall in some embodiments of this document) to form an accommodating space 300 with an open end (in some embodiments of this document, In the embodiment, the accommodating space 300 is also referred to as the first accommodating space. The peripheral sidewall 312 includes a first sidewall 3121 and a second sidewall 3122 disposed opposite each other. The main housing 31 also includes a partition assembly 313 disposed between the first sidewall 3121 and the second sidewall 3122 and at least partially separated from the first sidewall 3121 and the second sidewall 3122. A first rotating shaft mechanism 3111 and a second rotating shaft mechanism 3112 are respectively disposed on the partition assembly 313 and the second sidewall 3122. The movement housing 41 is disposed between the partition assembly 313 and the second sidewall 3122. A third rotating shaft mechanism 4101 and a fourth rotating shaft mechanism 4102 are respectively disposed on opposite sides of the movement housing 41. The first rotating shaft mechanism 3111 rotatably cooperates with the third rotating shaft mechanism 4101, and the second rotating shaft mechanism 3112 rotatably cooperates with the fourth rotating shaft mechanism 4102, thereby rotatably supporting the movement housing 41 on the main housing 31.

[0106] Specifically, as described above, the core housing 41 serves as the housing for the bone conduction speaker 40. The primary sound-producing components of the bone conduction speaker 40, such as the transducer, the vibration-transmitting face-mounting assembly 43, and the auxiliary face-mounting assembly 44, are all mounted on the core housing 41. For details, please refer to the descriptions of any of the aforementioned embodiments and will not be repeated here. The bottom wall 311 is connected to the peripheral sidewalls 312 to form the aforementioned housing space 300 with an open end. Among them, the partition assembly 313 is arranged between the first side wall 3121 and the second side wall 3122 to divide the accommodating space 300 into a space between the partition assembly 313 and the first side wall 3121 and a space between the partition assembly 313 and the second side wall 3122. The space between the partition assembly 313 and the first side wall 3121 can be used to accommodate other corresponding components of the speaker assembly 3, such as the air conduction speaker 50, etc. (if the speaker assembly 3 is only provided with a bone conduction speaker 40, then the space between the partition assembly 313 and the first side wall 3121 can be used to set other corresponding components), and the space between the partition assembly 313 and the second side wall 3122 can be used to set the bone conduction speaker 40, based on this, the space utilization rate of the speaker assembly 3 can be effectively improved.

[0107] Furthermore, the partition assembly 313 and the second side wall 3122 are respectively provided with a first rotating shaft mechanism 3111 and a second rotating shaft mechanism 3112, and the opposite sides of the movement housing 41 are respectively provided with a third rotating shaft mechanism 4101 and a fourth rotating shaft mechanism 4102, wherein the movement housing 41 is arranged between the partition assembly 313 and the second side wall 3122, and the first rotating shaft mechanism 3111 and the third rotating shaft mechanism 4101 are rotated and matched, and the second rotating shaft mechanism 3112 and the fourth rotating shaft structure are matched, based on which the movement While the shell 41 is connected to the main shell 31, the movement shell 41 can also rotate relative to the main shell 31, so that the bone conduction speaker 40 can rotate relative to the main shell 31. Based on this, when worn, the bone conduction speaker 40 can adjust its relative position relationship with the main shell 31 according to the user's face shape, so that the vibration plate 431 of the bone conduction speaker 40 can fit the facial area in front of the user's auricle as much as possible, thereby effectively improving the bone conduction sound transmission effect of the bone conduction speaker 40, and then effectively improving the sound quality of the headset 1.

[0108] Optionally, as shown in Figures 7, 15, and 16, in some embodiments, the partition assembly 313 is configured to produce elastic deformation along the spacing direction of the first side wall 3121 and the second side wall 3122 when the movement housing 41 is assembled to the main housing 31, and the elastic deformation capacity of the partition assembly 313 along the spacing direction of the first side wall 3121 and the second side wall 3122 is greater than the elastic deformation capacity of the first side wall 3121 and the second side wall 3122 along the spacing direction of the first side wall 3121 and the second side wall 3122. The elastic deformation capacity can be, for example, the degree of deformation produced when the same force is applied, or the size of the displacement produced. The greater the degree of deformation or the greater the displacement, the greater the elastic deformation capacity, and vice versa.

[0109] Specifically, the partition assembly 313 is configured as a component with a certain elastic deformation capability. When the movement shell 41 is assembled onto the main shell 31, the partition assembly 313 produces elastic deformation along the spacing direction of the first side wall 3121 and the second side wall 3122, so as to free up a sufficiently large assembly space for the movement shell 41, so that the movement shell 41 can be smoothly assembled onto the movement shell 41, thereby effectively improving the assembly efficiency of the movement shell 41 and the main shell 31. Furthermore, the elastic deformation capacity of the partition assembly 313 along the spacing direction of the first side wall 3121 and the second side wall 3122 is greater than the elastic deformation capacity of the first side wall 3121 and the second side wall 3122 along the spacing direction of the first side wall 3121 and the second side wall 3122. Based on this setting, it can effectively ensure that the first side wall 3121 and the second side wall 3122 maintain a sufficiently large structural strength to ensure the connection stability between the movement shell 41 and the main shell 31, while also effectively improving the assembly efficiency of the movement shell 41 and the main shell 31.

[0110] Optionally, as shown in Figures 7, 15, and 16, in some embodiments, the speaker assembly 3 further includes an air conduction speaker 50, which is disposed between the baffle assembly 313 and the first sidewall 3121. The space between the baffle assembly 313 and the first sidewall 3121 is used to accommodate the air conduction speaker 50, while the space between the baffle assembly 313 and the second sidewall 3122 can be used to accommodate other components such as the bone conduction speaker 40. This effectively improves the space utilization of the main housing 31. After the air conduction speaker 50 is mounted to the movement housing 41 in the manner described above, the air conduction vibration direction z2 is parallel to the spacing direction between the first sidewall 3121 and the second sidewall 3122.

[0111] Optionally, as shown in Figures 15 and 16, in some embodiments, the peripheral side wall 312 also includes a third side wall 3123 and a fourth side wall 3124 arranged opposite to each other and connected between the first side wall 3121 and the second side wall 3122, the partition assembly 313 includes a partition body 3131, and the partition body 3131 is connected between the third side wall 3123 and the fourth side wall 3124 to divide the accommodating space 300 into a first sub-space 302 located between the partition body 3131 and the first side wall 3121 and a second sub-space 303 located between the partition body 3131 and the second side wall 3122, the air conduction speaker 50 is arranged in the first sub-space 302, and the vibration direction of the air conduction speaker 50 points to or away from the first side wall 3121, the vibration direction of the bone conduction speaker 40 points to or away from the bottom wall 311, and the projection of the bone conduction speaker 40 along the vibration direction of the bone conduction speaker 40 falls into the second sub-space 303.

[0112] Specifically, the first subspace 302 located between the partition body 3131 and the first sidewall 3121 is the space between the partition assembly 313 and the first sidewall 3121 as described above. The second subspace 303 located between the partition body 3131 and the second sidewall 3122 is the space between the partition assembly 313 and the second sidewall 3122 as described above. The partition body 3131 divides the accommodating space 300 into the first subspace 302 and the second subspace 303 in the manner described above. The air conduction speaker 50 is disposed in the first subspace 302, and the projection of the bone conduction speaker 40 along the vibration direction of the bone conduction speaker 40 falls into the second subspace 303. In other words, the bone conduction speaker 40 is supported at the location of the second subspace 303 in the manner described in any of the above embodiments. This effectively improves the space utilization of the main housing 31. In addition, the vibration direction of the air conduction speaker 50 (also called the air conduction vibration direction z2) points toward or away from the first side wall 3121, and the vibration direction of the bone conduction speaker 40 (also called the bone conduction vibration direction z1) points toward or away from the bottom wall 311. Based on this, the air conduction vibration direction z2 and the bone conduction vibration direction z1 are intersected with each other or arranged almost vertically, thereby effectively reducing the interference of the bone conduction speaker 40 on the air conduction speaker 50 and effectively improving the sound quality of the air conduction speaker 50.

[0113] Optionally, as shown in Figures 15 and 16, in some embodiments, the partition body 3131 includes a first main body portion 3211, a second main body portion 3212 and a third main body portion 3213 arranged in sequence from the third side wall 3123 to the fourth side wall 3124. In the spacing direction between the first side wall 3121 and the second side wall 3122, the second main body portion 3212 is farther away from the first side wall 3121 than the first main body portion 3211 and the third main body portion 3213. The partition body 3131 also includes a first connecting portion 3214 connecting the first main body portion 3211 and the second main body portion 3212 along the spacing direction between the first side wall 3121 and the second side wall 3122, and a second connecting portion 3215 connecting the second main body portion 3212 and the third main body portion 3213. The end 51 of the air conduction speaker 50 facing the second side wall 3122 is embedded between the first connecting portion 3214 and the second connecting portion 3215.

[0114] Specifically, the first connecting part 3214, the second connecting part 3215 and the second main body 3212 are arranged in the above-mentioned spatial relationship, and a positioning space 302a with a positioning function is formed on the side of the first connecting part 3214 facing the first side wall 3121, the side of the second connecting part 3215 facing the first side wall 3121 and the side of the second main body 3212 facing the first side wall 3121, wherein the end 51 of the air conduction speaker 50 facing the second side wall 3122 is embedded in the positioning space 302a, and the positioning space 302a can effectively position the air conduction speaker 50, thereby effectively improving the installation accuracy of the air conduction speaker 50.

[0115] Optionally, referring to Figures 15-17, in some embodiments, the partition body 3131 also includes a third connecting portion 3216 connecting the first main body portion 3211 and the first side wall 3121 along the spacing direction of the first side wall 3121 and the second side wall 3122, and a fourth connecting portion 3217 connecting the third main body portion 3213 and the first side wall 3121, the third connecting portion 3216 and the fourth connecting portion 3217 are respectively provided with card slots 3218, and the air conduction speaker 50 is provided with flange portions 332 respectively embedded in the card slots 3218.

[0116] Specifically, during the assembly process of the air conduction speaker 50 and the main shell 31, the flange portion 332 is engaged with the slot 3218, so that the third connection portion 3216 and the fourth connection portion 3217 effectively position the air conduction speaker 50, which can effectively prevent the air conduction speaker 50 and the main shell 31 from deviating from the relative position during the assembly process, thereby effectively improving the installation accuracy of the air conduction speaker 50.

[0117] Optionally, referring to Figures 15 and 16, in some embodiments, the dimension L1 of the first subspace 302 along the spacing direction between the first side wall 3121 and the second side wall 3122 is smaller than the dimension L2 of the second subspace 303 along the spacing direction between the first side wall 3121 and the second side wall 3122.

[0118] Specifically, the air conduction speaker 50 vibrates the air to output the sound from the sound outlet, and the bone conduction speaker 40 vibrates and outputs the sound by making the vibration transmitting face-fitting component 43 fit the face. In order to better match the sound transmission effect of the air conduction speaker 50 with the sound transmission effect of the bone conduction speaker 40, so as to effectively improve the sound quality of the speaker assembly 3, the bone conduction speaker 40 is usually larger than the overall structural size of the air conduction speaker 50 considering the sensitivity and the working mode of face-to-face vibration. Therefore, by setting the dimension L1 of the first subspace 302 along the spacing direction of the first side wall 3121 and the second side wall 3122 to be smaller than the dimension L2 of the second subspace 303 along the spacing direction of the first side wall 3121 and the second side wall 3122, so that the spatial volume of the second subspace 303 is larger, the main shell 31 can accommodate the bone conduction speaker 40 with a larger structural size, so that the bone conduction speaker 40 has a better vibration effect, so that the sound transmission effect of the bone conduction speaker 40 and the sound transmission effect of the air conduction speaker 50 can be better matched, thereby effectively improving the sound quality of the bone conduction speaker 40.

[0119] Optionally, referring to Figures 7, 15 and 16, in some embodiments, the air conduction speaker 50 is inserted into the first subspace 302 from the open end 301 of the main shell 31, and the vibration direction of the air conduction speaker 50 (air conduction vibration direction z2) is perpendicular to the insertion direction of the air conduction speaker 50 relative to the first subspace 302, and the dimension of the air conduction speaker 50 along the vibration direction of the air conduction speaker 50 is smaller than the vertical dimension of the air conduction speaker 50 along the vibration direction of the air conduction speaker 50.

[0120] Specifically, the dimension of the air conduction speaker 50 along the air conduction vibration direction z2 includes the thickness of the air conduction speaker 50 , and the vertical dimension of the air conduction speaker 50 along the air conduction vibration direction z2 includes the width and length of the air conduction speaker 50 . While the overall structural dimensions of the air conduction speaker 50 remain unchanged, the thickness of the air conduction speaker 50 is set to be smaller than its length and width. This effectively ensures the sound quality of the air conduction speaker 50 while also effectively reducing the dimensions of the air conduction speaker 50 along the air conduction vibration direction z2 (i.e., the thickness of the air conduction speaker 50). Furthermore, based on the aforementioned structural dimensions, the air conduction speaker 50 is inserted into the first subspace 302 along an insertion direction perpendicular to the air conduction vibration direction z2. This effectively reduces the spatial dimensions of the main housing 31 occupied by the air conduction speaker 50 along the air conduction vibration direction z2. This allows the second subspace 303 to have a larger spatial dimension along the air conduction vibration direction z2, effectively improving the spatial utilization of the main housing 31 along the air conduction vibration direction z2. This allows the main housing 31 to accommodate a larger bone conduction speaker 40, thereby effectively improving the sound quality of the speaker assembly 3. In some embodiments, the bone conduction vibration direction z1 can serve as a reference direction for the insertion direction.

[0121] Optionally, referring to Figures 15 and 16, in some embodiments, the partition assembly 313 further includes an elastic arm 3132, which is connected to the side of the partition body 3131 facing away from the bottom wall 311, and the dimension of the elastic arm 3132 along the spacing direction between the third side wall 3123 and the fourth side wall 3124 is smaller than the dimension of the partition body 3131 along the spacing direction between the third side wall 3123 and the fourth side wall 3124, and the first rotating shaft mechanism 3111 is arranged on the elastic arm 3132.

[0122] Specifically, the elastic arm 3132 is connected to the side of the partition body 3131 facing away from the bottom wall 311. For example, in some embodiments, the elastic arm 3132 is connected to the side of the second body facing away from the bottom wall 311. The first rotating shaft mechanism 3111 is disposed on the elastic arm 3132. The elastic arm 3132 has the ability to elastically deform along the spacing direction. When the movement housing 41 and the main housing 31 are assembled, the elastic arm 3132 elastically deforms along the spacing direction between the first side wall 3121 and the second side wall 3122, thereby freeing up a sufficiently large assembly space for the movement housing 41. This allows the first rotating shaft mechanism 3111 and the third rotating shaft mechanism 4101, as well as the second rotating shaft mechanism 3112 and the fourth rotating shaft mechanism 4102, to easily and quickly cooperate, thereby effectively improving the assembly efficiency of the movement housing 41 and the main housing 31.

[0123] Optionally, referring to FIG. 15 and FIG. 16 , in some embodiments, the elastic arm 3132 further elastically abuts against a side of the air conduction speaker 50 facing away from the first side wall 3121 .

[0124] Specifically, after the bone conduction speaker 40 is installed in the second subspace 303 in the above manner, the elastic arm 3132 is squeezed by the bone conduction speaker 40 and elastically deformed toward the side of the air conduction speaker 50, so that the elastic arm 3132 abuts against the air conduction speaker 50 and provides abutting force for the air conduction speaker 50, effectively improving the fixing effect of the air conduction speaker 50 and the main shell 31.

[0125] Optionally, in some embodiments, the main shell 31 and the partition assembly 313 are integrally formed, the first rotating shaft mechanism 3111 is a rotating shaft, and the third rotating shaft mechanism 4101 is a rotating groove for receiving the rotating shaft.

[0126] Optionally, referring to Figures 6, 7 and 17, in some embodiments, the shell assembly 30 further includes a main cover body 32 covering the open end 301 of the main shell body 31, and the air conduction speaker 50 is provided with a first sound outlet 330, and the first sound outlet 330 is arranged toward the main cover body 32, and the main cover body 32 is provided with a second sound outlet 321 corresponding to the first sound outlet 330.

[0127] Specifically, the housing assembly 30, which houses and supports the air conduction speaker 50 and / or the bone conduction speaker 40, includes a detachably connected main housing 31 and a main cover 32. After the air conduction speaker 50 and / or the bone conduction speaker 40 are secured to the main housing 31 in the manner described above, the main cover 32 is then positioned over the open end 301 of the main housing 31. This effectively prevents assembly interference caused by the main cover 32 of the housing assembly 30 during installation of the air conduction speaker 50 and / or the bone conduction speaker 40, thereby effectively improving the installation efficiency of the speaker assembly 3. Furthermore, the air conduction speaker 50 and the main cover 32 are respectively provided with a first sound outlet 330 and a second sound outlet 321. The first sound outlet 330 and the second sound outlet 321 are arranged in correspondence with each other, allowing the sound emitted by the air conduction speaker 50 to be more efficiently transmitted through the first sound outlet 330 and along the second sound outlet 321 to the user's ears, effectively improving the sound transmission effect of the air conduction speaker 50.

[0128] Optionally, referring to Figures 5, 6 and 7, and further referring to Figure 15, in some embodiments, as described above, the bone conduction speaker 40 includes a transducer 42 and a vibration plate 431, the transducer 42 is arranged in the movement housing 41, and the vibration plate 431 is connected to the transducer 42 (the connection relationship between the transducer 42, the movement housing 41 and the vibration plate 431, the specific setting method can be referred to any embodiment of the transducer 42 described in this article, and will not be repeated in detail here), the first rotating shaft mechanism 3111 and the second rotating shaft mechanism 3112 are protruded from the outside of the open end 301 of the main housing 31, and an opening 320 is provided on the main cover 32, and the movement housing 41 and the vibration plate 431 are exposed through the opening 320 of the main cover 32.

[0129] Specifically, the movement housing 41 is connected to the first rotation axis mechanism 3111 and the second rotation axis mechanism 3112 through the third rotation axis mechanism 4101 and the fourth rotation axis mechanism 4102 respectively. The first rotation axis mechanism 3111 and the second rotation axis mechanism 3112 are protruded outside the opening end 301 of the main housing 31, so that the movement housing 41 and the vibration plate 431 and other components are exposed through the opening 320 of the main cover 32, so that the bone conduction speaker 40 does not occupy too much of the second sub-space 303. Based on this, the spatial volume of the second sub-space 303 can be made smaller, thereby effectively reducing the spatial volume of the main housing 31 and effectively improving the space utilization of the speaker assembly 3.

[0130] Optionally, referring to Figures 2 and 7, in some embodiments, the speaker assembly 3 further includes a battery 61 or a control circuit board 62 arranged in the second subspace 303, and the battery 61 supplies power to the air conduction speaker 50 and the bone conduction speaker 40 through the control circuit board 62. The control circuit board 62 is used to control the vibration of the air conduction speaker 50 and the bone conduction speaker 40.

[0131] Specifically, a portion of the second subspace 303 is used to house the bone conduction speaker 40, while the remaining portion is used to house the battery 61 or the control circuit board 62. This effectively improves the space utilization of the main housing 31 and further optimizes the overall structural dimensions of the speaker assembly 3. As described above, the speaker assembly 3 is used in the earphone 1, which may include two speaker assemblies 3, one of which is provided with the battery 61 and the other of which is provided with the control circuit board 62.

[0132] Optionally, referring to Figures 6-7, in some embodiments, the speaker assembly 3 includes: a housing assembly 30, an air conduction speaker 50, and a bone conduction speaker 40, wherein the housing assembly 30 includes a main housing 31. The air conduction speaker 50 is disposed within the main housing 31 using any of the embodiments herein; the bone conduction speaker 40 is rotatably supported on the main housing 31 and is capable of rotating relative to the main housing 31 along a predetermined rotation axis Ax1, wherein the vibration direction of the air conduction speaker 50 (the air conduction vibration direction z2) is parallel to the rotation axis Ax1, and the vibration direction of the bone conduction speaker 40 (the bone conduction vibration direction z1) is perpendicular to the rotation axis Ax1.

[0133] Specifically, as described in the above embodiment, a first rotating shaft mechanism 3111 and a second rotating shaft mechanism 3112 are provided on the main housing 31, and a third rotating shaft mechanism 4101 and a fourth rotating shaft mechanism 4102 are provided on the movement housing 41. The first rotating shaft mechanism 3111 and the third rotating shaft mechanism 4101 are rotatably connected, and the second rotating shaft mechanism 3112 and the fourth rotating shaft mechanism 4102 are rotatably connected. Based on this, the bone conduction speaker 40 is rotatably supported on the main housing 31. The bone conduction speaker 40 is rotatably connected to the main housing 31, allowing it to rotate relative to the main housing 31. When worn, the bone conduction speaker 40 can adjust its relative position to the main housing 31 based on the user's facial shape, so that the vibration plate 431 of the bone conduction speaker 40 fits the user's facial area in front of the tragus as closely as possible, thereby effectively improving the bone conduction sound transmission effect of the bone conduction speaker 40 and, therefore, the sound quality of the bone conduction speaker 40.

[0134] Furthermore, the vibration direction of the air conduction speaker 50 (i.e., the air conduction vibration direction z2) is parallel to the rotation axis Ax1. This effectively reduces interference from the air conduction speaker 50 with the bone conduction speaker 40. For example, by setting the air conduction vibration direction z2 parallel to the rotation axis Ax1, the air conduction speaker 50 is effectively prevented from causing the bone conduction speaker 40 to rotate about the rotation axis Ax1 during operation. Furthermore, the vibration direction of the bone conduction speaker 40 is perpendicular to the rotation axis Ax1, i.e., the bone conduction vibration direction z1 is set perpendicular to the air conduction vibration direction z2. This effectively reduces interference from the bone conduction speaker 40 with the air conduction speaker 50, thereby effectively improving the sound quality of the air conduction speaker 50.

[0135] Optionally, referring to Figure 7, in some embodiments, the main shell 31 includes a first bottom wall and a first peripheral side wall connected to the first bottom wall (wherein, in some embodiments, the first bottom wall is also referred to as the bottom wall 311, and the first peripheral side wall is also referred to as the peripheral side wall 312) to form a first accommodating space with one end open (wherein, in some embodiments, the first accommodating space is also referred to as the accommodating space 300), and the air conduction speaker 50 and the bone conduction speaker 40 are placed in the first accommodating space from the open end 301 of the main shell 31, and the vibration direction of the air conduction speaker 50 points toward or away from the first peripheral side wall, and the vibration direction of the bone conduction speaker 40 points toward or away from the first bottom wall.

[0136] Specifically, referring to FIG7, and further referring to FIG8, FIG11, FIG15 and FIG16, in some embodiments, the main housing 31 and the movement housing 41 are respectively provided with a rotating shaft mechanism that is detachably matched (wherein, in some embodiments, the rotating shaft mechanism includes a rotating shaft mechanism 31x provided on the main housing 31 and a rotating shaft mechanism 41x provided on the movement housing 41, wherein the rotating shaft mechanism 31x includes the first rotating shaft mechanism 3111 and the second rotating shaft mechanism 31 provided on the main housing 31 as described above). 12. The hinge mechanism 41x includes a third hinge mechanism 4101 and a fourth hinge mechanism 4102 provided on the movement housing 41. For details, please refer to the above content and will not be described in detail herein. The movement housing 41 is rotatably coordinated with the hinge mechanism 31x through the hinge mechanism 41x to be rotatably supported on the main housing 31. Based on this, the main housing 31 and the movement housing 41 are detachably connected through the hinge mechanism 31x and the hinge mechanism 41x, thereby effectively improving the assembly efficiency of the main housing 31 and the movement housing 41.

[0137] Optionally, in some embodiments, as described above, referring to Figures 1, 6 and 8, the speaker assembly 3 includes a shell assembly 30, an air conduction speaker 50 and a bone conduction speaker 40. The bone conduction speaker 40 is eccentrically arranged relative to the shell assembly 30. The bone conduction speaker 40 includes a vibration-transmitting face-attaching assembly 43. The vibration-transmitting face-attaching assembly 43 contacts the facial area in front of the user's tragus when worn, and is used to conduct bone-conducted sound waves. The air conduction speaker 50 is arranged in the shell assembly 30, and the air conduction speaker 50 is provided with a first sound outlet 330. The shell assembly 30 is provided with a second sound outlet 321 corresponding to the first sound outlet. When observed along the vibration direction of the bone conduction speaker 40 (that is, the bone-conducted vibration direction z1), the second sound outlet 321 is located on the periphery of the vibration-transmitting face-attaching assembly 43, and is used to conduct air-conducted sound waves.

[0138] Specifically, as described above, the bone conduction speaker 40 transmits sound to the user through bone-conducted vibration. The transducer 42 converts electrical signals into vibrations. It is connected to the vibration plate 431 and, based on the corresponding electrical signal, drives the vibration plate 431 to vibrate. The vibration direction of the vibration plate 431 is also referred to as the bone-conducted vibration direction z1, which is the vibration direction of the bone conduction speaker 40 during operation. The air conduction speaker 50 is provided with a first sound outlet 330, and the shell assembly 30 is provided with a second sound outlet 321. For example, the second sound outlet 321 is provided on the main cover body 32, and the first sound outlet 330 is provided toward the main cover body 32. The main cover body 32 is provided with a second sound outlet 321 corresponding to the first sound outlet 330. The sound generated by the air conduction speaker 50 is emitted from the first sound outlet 330 and guided to the user's ear through the second sound outlet 321. Based on this, the sound emitted by the air conduction speaker 50 can be efficiently transmitted to the user's ear, thereby effectively improving the sound transmission effect of the air conduction speaker 50, so as to effectively improve the sound quality of the sound transmitted to the user by the air conduction speaker 50. Moreover, in the worn state, when observed along the bone conduction vibration direction z1, the second sound outlet 321 is located on the periphery of the vibration-transmitting face-attaching component 43, thereby effectively reducing the sound transmission interference of the bone conduction speaker 40 on the air conduction speaker 50, thereby effectively improving the sound transmission effect of the air conduction speaker 50, and effectively improving the sound quality transmitted by the air conduction speaker 50 to the user.

[0139] Optionally, in some embodiments, the bone conduction speaker 40 further includes a movement shell 41, a transducer device 42 and an auxiliary face-sticking component 44. The outer shell component 30 includes a main shell 31. The movement shell 41 is supported on the main shell 31. The transducer device 42 is arranged inside the movement shell 41. The vibration-transmitting face-sticking component 43 includes a vibration plate 431. The vibration plate 431 is connected to the transducer device 42 and is in direct or indirect contact with the facial area in front of the user's tragus when worn. The auxiliary face-sticking component 44 is connected to the movement shell 41. When observed along the vibration direction of the vibration plate 431, the auxiliary face-sticking component 44 surrounds the periphery of the vibration plate 431 along the circumference of the vibration plate 431. Further referring to Figures 7, 8 and 17, the width of the auxiliary face-sticking component 44 facing the tragus is smaller than the width on the side away from the tragus. The auxiliary face-sticking component 44 is used to contact the facial area outside the vibration plate 431 when worn. The air conduction speaker 50 is arranged in the shell component 30, and the air conduction speaker 50 is provided with a first sound outlet 330. The shell component 30 is provided with a second sound outlet 321 corresponding to the first sound outlet 330. When observed along the vibration direction of the vibration plate 431, the second sound outlet 321 is located between the vibration plate 431 and the tragus, and at least partially located on the periphery of the auxiliary face-sticking component 44.

[0140] Specifically, as described above, the bone conduction speaker 40 transmits sound to the user through bone conduction vibration. Among them, the transducer 42 is a device that converts electrical signals into vibrations, which is connected to the vibration plate 431 and drives the vibration plate 431 to vibrate based on the corresponding electrical signal. The vibration direction of the vibration plate 431 is also called the bone conduction vibration direction z1, that is, the vibration direction of the bone conduction speaker 40 when it is working. Among them, the vibration plate 431 is the main component of the vibration face-mounted component 43. When the earphone 1 is in the wearing state, the vibration plate 431 is in direct or indirect contact with the facial area in front of the user's tragus. Based on this, driven by the transducer 42, the vibration plate 431 transmits sound to the user in the form of bone conduction vibration. In some embodiments, the vibration plate 431 contacts the user's facial area in front of the tragus indirectly, that is, indirectly contacts the facial area in front of the tragus via the soft vibration transmitter 432. In any embodiment of the bone conduction speaker 40 herein, similar descriptions of the vibration plate 431 contacting the user's facial area in front of the tragus can be understood as the vibration plate 431 indirectly contacting the facial area in front of the tragus via the soft vibration transmitter 432. For example, as described above, the vibration transmission face-mounted assembly 43 further includes a soft vibration transmitter 432 and a hard support 433. The edge region 432b of the soft vibration transmitter 432 and the hard support 433 are fixed to the hard support 433 by molding, and the middle region 432a of the soft vibration transmitter 432 is fixed to the vibration plate 431 by molding. The specific structure of the vibration transmission face-mounted assembly 43 can be found in the above description and will not be described in detail here. Among them, the soft vibration transmitter 432 is connected to the vibration plate 431 in the above-mentioned manner and is used to directly contact the human skin. That is, as described above, the soft vibration transmitter 432 contacts the facial area in front of the tragus and transmits sound to the user through bone conduction vibration. Based on this, the comfort of the bone conduction speaker 40 when transmitting sound to the user through bone conduction vibration can be effectively improved.

[0141] Furthermore, the auxiliary face-sticking assembly 44 provides auxiliary support. When worn, it contacts the user's facial area in front of the tragus, providing auxiliary support for the bone conduction speaker 40 along the bone conduction vibration direction z1. This effectively alleviates the supporting pressure on the vibration plate 431 along its vibration direction, thereby effectively reducing the workload of the transducer 42 and effectively improving the sound quality of the bone conduction speaker 40. Furthermore, when viewed along the bone conduction vibration direction z1, the auxiliary face-sticking assembly 44 surrounds the periphery of the vibration plate 431 along its circumference. This ensures that the periphery of the vibration plate 431 receives auxiliary support from the auxiliary face-sticking assembly 44, effectively improving the positioning of the vibration plate 431 by the auxiliary face-sticking assembly 44.

[0142] Furthermore, when viewed along the vibration direction of the vibration plate 431, the width of the auxiliary face-adhesive component 44 on the side facing the tragus is smaller than the width on the side facing away from the tragus. This configuration allows the vibration plate 431 as a whole to be closer to the user's tragus, thereby effectively improving the sound transmission effect of the bone conduction speaker 40 and, in turn, the sound quality of the bone conduction speaker 40. The specific structure of the auxiliary face-adhesive component 44 can be found in any of the embodiments of the auxiliary face-adhesive component 44 of this application and will not be described in detail here. Among them, the air conduction speaker 50 is provided with a first sound outlet 330, and the shell assembly 30 is provided with a second sound outlet 321. For example, the second sound outlet 321 is provided on the main cover body 32, and the first sound outlet 330 is provided toward the main cover body 32. The main cover body 32 is provided with a second sound outlet 321 corresponding to the first sound outlet 330. The sound generated by the air conduction speaker 50 is emitted from the first sound outlet 330 and guided to the user's ear through the second sound outlet 321. Based on this, the sound emitted by the air conduction speaker 50 can be efficiently transmitted to the user's ear, thereby effectively improving the sound transmission effect of the air conduction speaker 50, so as to effectively improve the sound quality of the sound transmitted to the user by the air conduction speaker 50. Moreover, when worn, when observed along the vibration direction of the vibration plate 431, the second sound outlet 321 is located between the vibration plate 431 and the tragus. Based on this, the second sound outlet 321 is arranged closer to the user's ear, so that the sound generated by the air conduction speaker 50 can be efficiently introduced into the user's ear through the second sound outlet 321, thereby effectively improving the sound transmission effect of the air conduction speaker 50, thereby effectively improving the sound quality of the sound transmitted to the user by the air conduction speaker 50.

[0143] Optionally, referring to Figures 4, 6, 7 and 16, in some embodiments, as described above, the shell assembly 30 includes a main cover body 32 covering the open end 301 of the main shell body 31, and the air conduction speaker 50 is provided with a first sound outlet 330, and the first sound outlet 330 is arranged toward the main cover body 32, and the main cover body 32 is provided with a second sound outlet 321 corresponding to the first sound outlet 330, wherein the sound generated by the air conduction speaker 50 is emitted from the first sound outlet 330 and directed to the user's ears through the second sound outlet 321.

[0144] Specifically, as described above, the housing assembly 30, which serves as a component for accommodating and supporting the air conduction speaker 50 and / or the bone conduction speaker 40, includes a detachably connected main housing 31 and a main cover 32. After the air conduction speaker 50 and / or the bone conduction speaker 40 are secured to the main housing 31 in the manner described above, the main cover 32 is then positioned over the open end 301 of the main housing 31. This effectively prevents assembly interference caused by the main cover 32 portion of the housing assembly 30 during installation of the air conduction speaker 50 and / or the bone conduction speaker 40, thereby effectively improving the installation efficiency of the speaker assembly 3. Furthermore, the air conduction speaker 50 and the main cover 32 are respectively provided with a first sound outlet 330 and a second sound outlet 321. The first sound outlet 330 and the second sound outlet 321 are correspondingly disposed, allowing the sound emitted by the air conduction speaker 50 to be more efficiently transmitted through the first sound outlet 330 and along the second sound outlet 321 to the user's ears, effectively improving the sound transmission effect of the air conduction speaker 50.

[0145] Optionally, in some embodiments, when worn, the vibration plate 431 is in direct or indirect contact with the facial area in front of the user's tragus. When observed along the vibration direction of the vibration plate 431, the second sound outlet 321 is located between the vibration plate 431 and the tragus. Based on this, the sound generated by the air conduction speaker 50 can be efficiently introduced into the user's ear through the second sound outlet 321, thereby effectively improving the sound transmission effect of the air conduction speaker 50, thereby effectively improving the sound quality of the sound transmitted to the user by the air conduction speaker 50.

[0146] Optionally, in some embodiments, when worn, the second sound outlet 321 is arranged toward the human ear, so that the sound generated by the air conduction speaker 50 can be more efficiently introduced into the user's ear through the second sound outlet 321, thereby effectively improving the sound transmission effect of the air conduction speaker 50, thereby effectively improving the sound quality transmitted from the air conduction speaker 50 to the user.

[0147] Optionally, referring to Figures 6 and 7, in some embodiments, the housing assembly 30 further includes a main cover 32, the main housing 31 includes a bottom wall 311 and a peripheral side wall 312 connected to the bottom wall 311 to form a receiving space 300 with an open end, the main cover 32 is provided on the open end of the main housing 31, the air conduction speaker 50 is provided in the receiving space 300, the second sound outlet 321 is provided on the main cover 32, the main cover 32 is provided with an opening 320, and the core housing 41 and the vibration plate 431 are exposed through the opening 320. For example, as described above, the main housing 31 is provided with a first rotating shaft mechanism 3111 and a second rotating shaft mechanism 3112, and the core housing 41 is provided with a third rotating shaft mechanism 4101 and a fourth rotating shaft mechanism 4102. Among them, the first rotating shaft mechanism 3111 and the second rotating shaft mechanism 3112 are protruded from the outside of the open end 301 of the main shell 31, wherein the first rotating shaft mechanism 3111 and the third rotating shaft mechanism 4101 are rotatably matched, and the second rotating shaft mechanism 3112 and the fourth rotating shaft mechanism 4102 are rotatably matched, so that the bone conduction speaker 40 (as described above, the bone conduction speaker 40 at least includes a core shell 41 and a vibration plate 431) is integrally mounted on the accommodating space 300, while the core shell 41 and the vibration plate 431 are exposed through the opening 320 of the main cover 32. Based on this, after the bone conduction speaker 40 is assembled with the main shell 31, it does not occupy too much of the accommodating space 300 (the second subspace 303), so that the spatial volume of the accommodating space 300 (the second subspace 303) can be made smaller, thereby reducing the spatial volume of the main shell 31, thereby effectively improving the space utilization rate of the speaker assembly 3.

[0148] Optionally, as shown in Figures 4, 5, 6, 7, 16 and 17, in some embodiments, the air conduction speaker 50 is inserted into the accommodating space 300 from the open end of the main shell 31, and the air conduction speaker 50 is also provided with a first pressure relief port 331, and the first sound outlet 330 and the first pressure relief port 331 are arranged opposite to each other along the insertion direction of the air conduction speaker 50 relative to the main shell 31 (in the above content, the insertion direction is also referred to as the insertion direction). Based on this, when the air conduction speaker 50 is relieving pressure along the first pressure relief port 331, the mutual interference with the air conduction speaker when transmitting sound along the first sound outlet 330 can be effectively reduced, thereby effectively improving the sound quality of the air conduction speaker 50. A second pressure relief port 304 corresponding to the first pressure relief port 331 is provided on the bottom wall 311. Specifically, the bottom wall 311 and the first pressure relief port 331 are arranged opposite to each other. The second pressure relief port 304 is arranged on the bottom wall 311, so that the pressurized air discharged from the air conduction speaker 50 and thus the first pressure relief port 331 can be more efficiently discharged from the external space of the speaker assembly 3 through the second pressure relief port 304, thereby achieving more efficient pressure relief.

[0149] Optionally, as shown in Figures 11 and 18, in some embodiments, the bone conduction speaker 40 further includes a lead 46, and a shell lead hole 4104 is provided on the movement shell 41. The lead 46 extends into the movement shell 41 through the shell lead hole 4104 and is electrically connected to the transducer device 42. The extension direction of the shell lead hole 4104 intersects with the rotation axis Ax1.

[0150] Specifically, the lead 46 is used to electrically connect to the transducer device 42 so as to guide the electrical signal to the transducer device 42. The housing lead hole 4104 is used to lead the lead 46 connected to the transducer device 42 in the core housing 41 to a functional space outside the core housing 41. The housing lead hole 4104 is provided on the core housing 41, and the lead 46 extends into the core housing 41 through the housing lead hole 4104 so as to be electrically connected to the transducer device 42. The extension direction of the housing lead hole 4104 (wherein the extension direction of the housing lead hole 4104 is perpendicular to the bottom wall 411 of the core housing 41) intersects with the rotation axis Ax1. Based on this, the stretching of the lead 46 by the bone conduction speaker 40 when rotating around the rotation axis Ax1 can be effectively reduced, thereby effectively improving the service life of the lead 46.

[0151] Optionally, referring to Figures 7, 11, 14 and 18, in some embodiments, the movement housing 41 includes a second bottom wall and a second peripheral side wall connected to the second bottom wall (wherein, in some embodiments, the second bottom wall is also referred to as the bottom wall 411, and the second peripheral side wall is also referred to as the peripheral side wall 412) to form a second accommodating space with an open end (wherein, in some embodiments, the second accommodating space is also referred to as the accommodating space 410), the transducer device 42 is arranged in the second accommodating space, the second bottom wall is arranged toward the first bottom wall (that is, the bottom wall) 311 compared to the open end 413 of the movement housing 41, the housing lead hole 4104 is arranged on the second bottom wall, the rotating shaft mechanism 41x on the movement housing 41 is arranged on the second peripheral side wall, the speaker assembly 3 also includes a control circuit board 62 located between the first bottom wall and the movement housing 41, and the lead 46 is connected to the control circuit board 62.

[0152] Specifically, the second bottom wall is connected to the second circumferential side wall to form a second accommodating space with one end open for accommodating the transducer device 42, wherein, as described above, the end of the movement housing 41 is the end of the second circumferential side wall facing away from the first bottom wall (i.e., the bottom wall 311). Along the bone conduction vibration direction z1, the second bottom wall is located between the second circumferential side wall and the first bottom wall, i.e., the second bottom wall described above is arranged toward the first bottom wall relative to the open end 413 of the movement housing 41. The rotating shaft mechanism 41x (e.g., the third rotating shaft mechanism 4101 and the fourth rotating shaft mechanism 4102) on the movement housing 41 is arranged on the second circumferential side wall, and the control circuit board 62 is arranged between the first bottom wall and the movement housing 41, i.e., the control circuit board 62 is arranged between the first bottom wall and the second bottom wall, so as to effectively utilize the extra space between the second bottom wall and the movement housing 41 and improve the space utilization rate of the main housing 31.

[0153] Optionally, as shown in Figures 11, 15 and 18, in some embodiments, along the vibration direction of the vibration plate 431 (that is, along the bone conduction vibration direction z1), the distance from the rotating shaft mechanism 41x on the movement housing 41 to the second bottom wall is smaller than the distance from the rotating shaft mechanism 41x on the movement housing 41 to the opening end 413 of the movement housing 41.

[0154] Specifically, in the bone conduction vibration direction z1, the distance between the hinge mechanism 41x on the movement housing 41 and the second bottom wall is shorter than the distance between the hinge mechanism 41x on the movement housing 41 and the open end 413 of the movement housing 41. This places the hinge mechanism 41x closer to the second bottom wall, and therefore the bottom of the movement housing 41. This allows the majority of the bone conduction speaker 40 to protrude from the second subspace, effectively reducing the percentage of the bone conduction speaker 40 occupying the second subspace. Furthermore, the hinge mechanism 41x and the second bottom wall can be arranged nearly coplanar. This allows the housing lead hole 4104 to be located on the second bottom wall, with the extension direction of the housing lead hole 4104 intersecting the rotation axis Ax1. This effectively reduces the stretching of the lead wire 46 when the bone conduction speaker 40 rotates about the rotation axis Ax1, thereby effectively improving the service life of the lead wire 46. The rotating shaft mechanism 41 x and the second bottom wall are located almost on the same plane, which enables the bone conduction speaker 40 to protrude from the second subspace as a whole, thereby effectively reducing the occupation rate of the second subspace by the bone conduction speaker 40 .

[0155] In conjunction with Figure 1, an embodiment of the present application provides an earphone 1. The earphone 1 includes a wearing assembly 2 and a speaker assembly 3. The wearing assembly 2 and the housing assembly 30 of the speaker assembly 3 are fixedly connected. The wearing assembly 2 can stably support the speaker assembly 3 at a corresponding position on the face of a person. The speaker assembly 3 can receive a corresponding signal and generate vibration.

[0156] 19 and 20 , an embodiment of the present application provides a speaker assembly 3 . The speaker assembly 3 includes a housing assembly 30 and a bone conduction speaker 40 .

[0157] The housing assembly 30 is provided with a receiving space 300, which can be used to receive the bone conduction speaker 40. The housing assembly 30 can provide mechanical support for the bone conduction speaker 40. The receiving space 300 can also be used to receive components such as batteries, electronic control boards or control circuits for driving the bone conduction speaker 40.

[0158] The bone conduction speaker 40 includes a core housing 41 and a transducer 42. The core housing 41 is supported on the outer shell assembly 30 and is at least partially located within the accommodating space 300. The core housing 41 is provided with an installation space 410, within which the transducer 42 is located. The volume of the installation space 410 is smaller than that of the accommodating space 300. The installation space 410 can accommodate the transducer 42, while the accommodating space 300 can accommodate at least a portion of the core housing 41 and other components. Optionally, the accommodating space 300 can also accommodate the air conduction speaker 50. The transducer 42 can convert electrical energy into vibrations. The bone conduction speaker 40 includes a vibration plate 424 connected to the transducer 42. At least a portion of the vibration plate 424 protrudes outward through an opening to conform to the face. Vibrations generated by the transducer 42 can be further received by the user through bone conduction by being placed close to the face.

[0159] Furthermore, referring to Figures 19 to 21 , the movement housing 41 is provided with a first sound-introducing hole 4106 communicating with the installation space 410, and the outer shell assembly 30 is provided with a second sound-introducing hole 350 communicating with the first sound-introducing hole 4106. The first sound-introducing hole 4106 is connected to the outside world through the second sound-introducing hole 350. Since the first sound-introducing hole 4106 and the second sound-introducing hole 350 connect the installation space 410 with the outside world, the air pressure changes caused by the vibration of the transducer device 42 in the installation space 410 can be balanced through the first sound-introducing hole 4106 and the second sound-introducing hole 350.

[0160] In some cases, the sound transmitted to the outside from the first sound inlet hole 4106 and the second sound inlet hole 350 by the transducer device 42 is in opposite phase to the sound leakage generated by the self-diaphragm 424 of the transducer device 42. The sound leakage and the sound output from the first sound inlet hole 4106 and the second sound inlet hole 350 can at least partially offset each other, thereby further improving the sound leakage phenomenon of the speaker assembly 3 and further enhancing the sound quality effect of the speaker assembly 3.

[0161] Compared to the aforementioned solution of this application, if the transducer device 42 is directly mounted within the larger housing space 300, the frequency at which the sound waves generated by the transducer device 42 resonate with the cavity formed by the housing assembly 30 is relatively low. In this case, during operation of the bone conduction speaker 40, the sound waves generated by the transducer device 42 are very likely to resonate with the housing assembly 30. This can lead to increased sound leakage and a sudden change in the sound wave frequency response, preventing the sound leakage from being effectively coherently cancelled. Furthermore, with a relatively low resonant frequency, the acoustic performance of the bone conduction speaker 40 cannot be guaranteed to be balanced. In an embodiment of the present application, a movement shell 41 is provided to accommodate the transducer 42, and the outer shell assembly 30 is used to accommodate the movement shell 41 and other parts. With such a configuration, the smaller installation space 410 is separated from the larger accommodating space 300 by the movement shell 41, and the resonance frequency of the cavity formed by the sound waves generated by the transducer 42 and the movement shell 41 with a smaller installation space 410 will be relatively high. In this case, on the one hand, the sound waves generated by the transducer 42 are not easy to resonate with the movement shell 41, and on the other hand, the sudden change of the sound waves generated by the transducer 42 in the lower frequency band due to resonance can be reduced, which is more conducive to the coherent cancellation of the sound leakage at the vibration plate 424 and the sound leakage at the sound guide hole 4106, which is beneficial to improving the sound leakage phenomenon of the speaker assembly 3, and thus can enhance the sound quality effect of the speaker assembly 3.

[0162] Specifically, in some embodiments, referring to FIG. 20 , the first sound introduction hole 4106 and the second sound introduction hole 350 are each connected to the accommodation space 300 located outside the movement housing 41. In other words, the first sound introduction hole 4106 and the second sound introduction hole 350 can be connected to each other through the accommodation space 300 outside the movement housing 41. The air pressure changes and the resulting air-conducted sound generated by the vibration of the transducer device 42 can be transmitted from the first sound introduction hole 4106 through the accommodation space 300 to the second sound introduction hole 350, and then to the outside world, thereby reducing sound leakage from the speaker assembly 3.

[0163] Optionally, in some embodiments, the first sound introduction hole 4106 and the second sound introduction hole 350 are disposed opposite each other along the radial direction of the transducer device 42. The transducer device 42 has a vibration direction, and the radial direction of the transducer device 42 refers to a direction perpendicular to the vibration direction of the transducer device 42. That is, the depth direction of the first sound introduction hole 4106 and the second sound introduction hole 350 is perpendicular to the vibration direction of the transducer device 42.

[0164] The vibrations transmitted from the first sound inlet hole 4106 and the second sound inlet hole 350 of the transducer device 42 are transmitted in the form of air conduction. By arranging the first sound inlet hole 4106 and the second sound inlet hole 350 relative to each other along the radial direction of the transducer device 42, the sound waves in the installation space 410 can be transmitted from the first sound inlet hole 4106 and the second sound inlet hole 350, thereby improving the efficiency of the sound wave transmission and making it easier for the first sound inlet hole 4106 and the second sound inlet hole 350 to achieve the aforementioned technical effects, so as to further improve the sound leakage phenomenon of the speaker assembly 3.

[0165] In some embodiments, there are multiple first sound introduction holes 4106, which are spaced apart along the circumference of the movement housing 41 on the circumferential sidewall 412 of the movement housing 41. In other embodiments, there are multiple second sound introduction holes 350, which are spaced apart along the circumference of the outer shell assembly 30 on the circumferential sidewall 312 of the outer shell assembly 30.

[0166] In yet other embodiments, there are multiple first sound introduction holes 4106, each of which is spaced apart along the circumference of the movement housing 41 on the circumferential sidewall 412 of the movement housing 41. Furthermore, there are multiple second sound introduction holes 350, each of which is spaced apart along the circumference of the outer shell assembly 30 on the circumferential sidewall 312 of the outer shell assembly 30. By providing multiple first sound introduction holes 4106 on the circumferential sidewall 412 of the movement housing 41 and / or multiple second sound introduction holes 350 on the circumferential sidewall 312 of the outer shell assembly 30, the sound waves generated by the transducer device 42 can be transmitted to the outside world along multiple different directions, thereby optimizing the effect of the first sound introduction holes 4106 and the second sound introduction holes 350 in reducing sound leakage.

[0167] In other embodiments, as shown in FIG19 , the housing assembly 30 includes a channel member 36 having a sound guide channel 360 formed therein. The channel member 36 is located within the accommodating space 300. The ends of the sound guide channel 360 are connected to the first sound guide hole 4106 and the second sound guide hole 350, respectively. The first sound guide hole 4106, the sound guide channel 360, and the second sound guide hole 350 can connect the installation space 410 with the outside world, thereby reducing sound leakage from the speaker assembly 3.

[0168] In some embodiments, by providing an independent channel member 36, the sound waves in the installation space 410 can be directly transmitted to the outside without passing through the accommodating space 300, thereby reducing the interference of the sound waves on the components in the accommodating space 300 and reducing the possibility of the sound waves resonating with the shell assembly 30 after entering the accommodating space 300.

[0169] The volume of the sound-conducting channel 360 is smaller than the volume of the accommodating space 300 located outside the movement housing 41. This arrangement allows the sound waves generated by the transducer 42 to resonate at a relatively high frequency with the channel member 36, mitigating sudden changes in lower-frequency sound waves and facilitating coherent cancellation of far-field sound leakage, thereby reducing the occurrence of sound leakage.

[0170] In summary, by setting the volume of the installation space 410 to be smaller than the volume of the accommodating space 300, and setting the volume of the sound guide channel 360 to be smaller than the volume of the accommodating space 300, the resonance frequency of the sound waves generated by the transducer device 42 with the movement housing 41 and the channel member 36 can be relatively high during the conduction process, so that the sound waves generated by the transducer device 42 are not easy to resonate with the components on the conduction path during the conduction process, thereby reducing the sound leakage problem caused by resonance.

[0171] Optionally, in some embodiments, the volume of the sound-conducting channel 360 is smaller than the volume of the installation space 410 , which can further increase the resonance frequency of the sound waves and the channel member 36 , making the channel member 36 less likely to resonate with the sound waves, thereby improving the sound leakage phenomenon.

[0172] In some embodiments, the housing assembly 30 includes a main housing 31 having an open end and a main cover 32 covering the open end 301 of the main housing 31. With this arrangement, during assembly of the speaker assembly 3, the battery, electronic control board, control circuit, and bone conduction speaker 40 can be assembled with the main housing 31 or the main cover 32 before the main cover 32 is assembled with the main housing 31. This method simplifies assembly and improves assembly efficiency. The core housing 41 is supported on the main housing 31 or the main cover 32. Optionally, the core housing 41 can be integrally formed with the main cover 32 or the main housing 31. The main cover 32 is provided with an opening that communicates with the accommodating space 300. At least a portion of the bone conduction speaker 40 can pass through the opening provided in the main cover 32, thereby conforming to the face. At least a portion of the channel member 36 is located on the main cover 32. The main cover 32 can be used to mount the channel member 36 or can be integrally formed with at least a portion of the channel member 36.

[0173] In some embodiments, referring to FIG. 19 , the channel member 36 includes a first channel portion 361 and a second channel portion 362. The first channel portion 361 is located on the main cover 32, and the second channel portion 362 is located on the main housing 31. When the main cover 32 and the main housing 31 are assembled, the first channel portion 361 and the second channel portion 362 cooperate to form the sound guide channel 360. For example, the first channel portion 361 can be a through-slot provided in the main cover 32, and the second channel portion 362 can be a through-slot provided in the main housing 31. When the main cover 32 and the main housing 31 are assembled, the two channels can be spliced ​​together to form the complete sound guide channel 360. The first channel portion 361 and the second channel portion 362 can be the first channel member 36 and the second channel member 36 respectively installed on the main cover 32 and the main housing 31, or can be the first through-slot and the second through-slot machined or injection-molded on the main cover 32 and the main housing 31, respectively. No specific limitation is provided herein. Through the above method, the assembly of the channel member 36 can be simplified, and the process of forming the sound guide channel 360 can be integrated into the assembly process of the main cover 32 and the main shell 31, which is beneficial to improving the assembly efficiency of the speaker assembly 3.

[0174] In some embodiments, in conjunction with Figures 19 and 20, the speaker assembly 3 includes an air conduction speaker 50, which is arranged in the accommodating space 300. The air conduction speaker 50 is provided with a first sound outlet 330, and the air conduction speaker 50 emits sound outward through the first sound outlet 330. The outer shell assembly 30 is provided with a second sound outlet 321 connected to the accommodating space 300. The sound waves generated by the air conduction speaker 50 can be emitted to the outside through the second sound outlet 321, and then enter the human ear through air conduction. The first sound outlet 330 and the second sound guide hole 350 are arranged at intervals, thereby reducing the mutual influence between the sound emitted by the bone conduction speaker 40 from the second sound guide hole 350 and the sound emitted by the air conduction speaker 50, thereby improving the acoustic performance of the speaker assembly 3. Specifically, the housing assembly 30 is provided with an opening that communicates with the accommodating space 300. The bone conduction speaker 40 includes a vibration plate 424, which is connected to the transducer device 42. At least a portion of the vibration plate 424 protrudes outward through the opening to conform to the face. When viewed along the vibration direction of the vibration plate 424, the second sound outlet 321 is located between the vibration plate 424 and the tragus. This arrangement places the sound output position of the air conduction speaker 50 closer to the ear canal, allowing the sound waves generated by the air conduction speaker 50 to enter the ear canal at a closer distance, thereby reducing sound wave losses during propagation and further improving the acoustic performance of the speaker assembly 3.

[0175] Specifically, in some embodiments, the housing assembly 30 further includes a main housing 31 and a main cover 32. The main cover 32 is disposed over the open end of the main housing 31, and the second sound outlet 321 is disposed on the main cover 32. With this arrangement, during assembly of the speaker assembly 3, the battery, electronic control board, control circuit, air conduction speaker 50, and bone conduction speaker 40 can be assembled with the main housing 31 or the main cover 32 before the main cover 32 is assembled with the main housing 31. This method simplifies assembly and improves assembly efficiency.

[0176] 21 to 23 , the movement housing 41 is supported on the main housing 31 or the main cover 32. Optionally, the movement housing 41 can be integrally formed with the main cover 32 or the main housing 31. The main cover 32 is provided with an opening connected to the accommodating space 300. The movement housing 41 and the vibration plate 424 are at least partially exposed through the opening and pass through the opening provided on the main cover 32 so as to fit the face of a person. The main housing 31 includes a bottom wall 311 and a peripheral side wall 312 connected to the bottom wall 311 to form an accommodating space 300 with an opening at one end. The second sound introduction hole 350 is located on the peripheral side wall 312, and the sound waves derived from the first sound introduction hole 4106 can be conducted to the outside through the peripheral side wall 312 of the main housing 31. By providing a second sound outlet 321 for the air conduction speaker 50 to emit sound and an opening for the bone conduction speaker 40 to emit sound on the main cover body 32, the vibration of the bone conduction speaker 40 and the vibration of the air conduction speaker 50 can be received by the user on one side of the main cover body 32 by respectively fitting with the human face and air conduction, so that the speaker assembly 3 of the present application can have good acoustic performance.

[0177] In some embodiments, the air conduction speaker 50 is inserted into the accommodating space 300 from the open end 301 of the main housing 31. The air conduction speaker 50 is also provided with a first pressure relief port 331, and a second pressure relief port 304 corresponding to the first pressure relief port 331 is provided on the bottom wall 311. When the air conduction speaker 50 generates sound waves, the air pressure inside it changes. By providing the first pressure relief port 331, the air pressure inside the air conduction speaker 50 can be balanced when the sound is generated. The second pressure relief port 304 can connect the first pressure relief port 331 with the outside world, so that the outside air can enter the air conduction speaker 50 through the second pressure relief port 304 and the first pressure relief port 331. The first pressure relief port 331 and the second pressure relief port 304 can be connected through the housing assembly 30, or by providing a connecting piece in the accommodating space 300. No specific limitation is given here.

[0178] Furthermore, the first sound outlet 330 and the first pressure relief vent 331 are disposed opposite each other along the direction in which the air conduction speaker 50 is inserted relative to the main housing 31. Thus, the direction in which sound is emitted from the air conduction speaker 50 is opposite to the direction in which sound is emitted from the first pressure relief vent 331, thereby reducing the effect of sound leakage from the first pressure relief vent 331 on the sound emitted from the first sound outlet 330 and improving the acoustic performance of the speaker assembly 3.

[0179] In some embodiments, the core housing 41 is rotatably supported on the outer shell assembly 30 and is capable of rotating relative to the outer shell assembly 30 along a predetermined rotation axis. With this arrangement, when the earphones 1 are worn and the bone conduction speaker 40 is in contact with the face, the core housing 41 and the vibration plate 424 can rotate under the combined pressure of the wearing member and the support force of the face on the bone conduction speaker 40, thereby further conforming the vibration plate 424 to the face, making the contact pressure between the vibration plate 424 and the face more uniform, and thus achieving a better sound transmission effect for the bone conduction speaker 40. The vibration direction of the air conduction speaker 50 is parallel to the rotation axis, while the vibration direction of the bone conduction speaker 40 is perpendicular to the rotation axis. With this arrangement, during the rotation of the bone conduction speaker 40, since the vibration direction of the bone conduction speaker 40 is perpendicular to the rotation axis, the vibration direction of the bone conduction speaker 40 is always perpendicular to the vibration direction of the air conduction speaker 50. This layout can reduce the impact of the vibration of the bone conduction speaker 40 on the vibration of the air conduction speaker 50, making the vibrations of the two more relatively independent, thereby improving the acoustic performance of the speaker assembly 3.

[0180] In conjunction with Figure 24, an embodiment of the present application provides a speaker assembly 3. The speaker assembly 3 includes a housing assembly 30, a bone conduction speaker 40, and an air conduction speaker 50. The housing assembly 30 includes a main shell 31, and the main shell 31 forms a storage space 300 with one end open. The storage space 300 can be used to accommodate the bone conduction speaker 40 and the air conduction speaker 50. The housing assembly 30 can provide mechanical support for the bone conduction speaker 40. The storage space 300 can also be used to accommodate components such as batteries, electronic control boards, or control circuits for driving the bone conduction speaker 40. The bone conduction speaker 40 includes a core housing 41 and a transducer 42. The core housing 41 is rotatably supported on the main shell 31 and is partially located in the storage space 300. When the earphone 1 is worn, when the bone conduction speaker 40 is in contact with the face, the movement shell 41 can rotate under the cooperation of the pressure of the wearing piece and the supporting force of the face on the bone conduction speaker 40, so that the vibration plate 424 of the bone conduction speaker 40 can further fit the face, making the pressure of the vibration plate 424 in contact with the face more uniform, so that the bone conduction speaker 40 has a better sound transmission effect.

[0181] In some embodiments, the movement housing 41 is provided with an installation space 410, the volume of which is smaller than the volume of the accommodation space 300. The transducer 42 is disposed within the installation space 410. If the transducer 42 is directly mounted within the larger accommodation space 300, the frequency at which the sound waves generated by the transducer 42 resonate with the housing assembly 30 is relatively low. In this case, during operation of the bone conduction speaker 40, the sound waves generated by the transducer 42 are very likely to resonate with the housing assembly 30, which, on the one hand, will increase sound leakage, and on the other hand, will cause a sudden change in the sound wave frequency response, preventing the sound leakage from being effectively coherently canceled. Furthermore, at a relatively low resonant frequency, the acoustic performance of the bone conduction speaker 40 cannot be guaranteed to be relatively balanced. In an embodiment of the present application, a movement shell 41 is provided to accommodate the transducer 42, and the outer shell assembly 30 is used to accommodate the movement shell 41 and other parts. With such a configuration, the smaller installation space 410 is separated from the larger accommodating space 300 by the movement shell 41, and the resonance frequency of the cavity formed by the sound waves generated by the transducer 42 and the movement shell 41 with a smaller installation space 410 will be relatively high. In this case, on the one hand, the sound waves generated by the transducer 42 are not easy to resonate with the movement shell 41, and on the other hand, the sudden change of the sound waves generated by the transducer 42 in the lower frequency band due to resonance can be reduced, which is more conducive to the coherent cancellation of the sound leakage at the vibration plate 424 and the sound leakage at the sound guide hole 4106, which is beneficial to improving the sound leakage phenomenon of the speaker assembly 3, and thus can enhance the sound quality effect of the speaker assembly 3.

[0182] In some embodiments, referring to Figures 21 to 24 , the movement housing 41 is provided with a sound-introducing hole 4106 that communicates with the installation space 410. The sound-introducing hole 4106 connects the installation space 410 with the outside world, allowing the air pressure changes caused by the vibration of the transducer 42 in the installation space 410 to be balanced through the sound-introducing hole 4106. In some cases, the sound transmitted from the transducer 42 to the outside world through the sound-introducing hole 4106 is in phase with the sound leakage generated by the transducer 42, and the sound leakage and the sound output from the sound-introducing hole 4106 can cancel each other out, thereby improving the sound leakage of the speaker assembly 3.

[0183] In some embodiments, when the speaker assembly 3 is in the worn state, the sound-introducing hole 4106 remains exposed relative to the open end of the main shell 31. Optionally, the sound-introducing hole 4106 can be partially exposed relative to the open end of the main shell 31, that is, a portion of the sound-introducing hole 4106 can be directly connected to the outside world, and the other portion can be connected to the accommodating space 300 or the opening of the main shell 31. Optionally, the sound-introducing hole 4106 can be completely exposed relative to the open end of the main shell 31, that is, the sound-introducing hole 4106 is directly connected to the outside world without passing through the accommodating space 300. Specifically, the movement shell 41 includes a bottom wall 411 and a peripheral side wall 412 connected to the bottom wall 411 to form an installation space 410. Part of the peripheral side wall 412 and the bottom wall 411 are located in the accommodating space 300, and the peripheral side wall 412 also includes a portion exposed relative to the main shell 31 through the open end 301 in the worn state. The sound-introducing hole 4106 is located in part or all of the exposed portion of the peripheral side wall 412. In other words, the sound-introducing hole 4106 provided on the movement shell 41 can be directly connected to the outside world without passing through the accommodating space 300. By directly conducting the sound waves in the installation space 410 to the outside world without passing through the accommodating space 300 through the sound-introducing hole 4106, the interference of the sound waves on the components in the accommodating space 300 and the possibility of the sound waves resonating with the outer shell assembly 30 after entering the accommodating space 300 can be reduced, which is beneficial to improving the sound leakage phenomenon of the speaker assembly 3. In some embodiments, the ratio of the extension length to the width of the sound-introducing hole 4106 is 3 to 8, for example, 5 to 7, specifically 5.5, 6 or 6.5. The sound-introducing hole 4106 having a suitable extension length and width can make the sound waves more convenient to transmit, and make the sound waves have a suitable resonance frequency at the sound-introducing hole 4106, which is beneficial to improving the acoustic performance of the speaker assembly 3.

[0184] In some embodiments, the main housing 31 is provided with a first rotating shaft mechanism 3111 and a second rotating shaft mechanism 3112, which are opposed to each other. A third rotating shaft mechanism 4101 and a fourth rotating shaft mechanism 4102 are respectively provided on opposite sides of the peripheral sidewall 412. The third rotating shaft mechanism 4101 and the fourth rotating shaft mechanism 4102 extend along a predetermined axis. The first rotating shaft mechanism 3111 cooperates with the third rotating shaft mechanism 4101, and the second rotating shaft mechanism 3112 cooperates with the fourth rotating shaft mechanism 4102, thereby rotatably supporting the movement housing 41 on the main housing 31. The first rotating shaft mechanism 3111 and the third rotating shaft mechanism 4101 form a rotation pair, while the second rotating shaft mechanism 3112 and the fourth rotating shaft mechanism 4102 form a rotation pair. Taking the first rotating shaft mechanism 3111 and the third rotating shaft mechanism 4101 as an example, the configuration of the rotational pair can be to form a hole-shaped or groove-shaped first rotating shaft mechanism 3111 on the main housing 31, and to dispose a shaft-shaped third rotating shaft mechanism 4101 on the circumferential sidewall 412, with the third rotating shaft mechanism 4101 inserted into the first rotating shaft mechanism 3111 to form the rotational pair. Alternatively, a hole-shaped or groove-shaped third rotating shaft mechanism 4101 can be formed on the circumferential sidewall 412, and to dispose a shaft-shaped first rotating shaft mechanism 3111 on the main housing 31, with the first rotating shaft mechanism 3111 inserted into the third rotating shaft mechanism 4101 to form the rotational pair. The coordination between the first rotating shaft mechanism 3111 and the third rotating shaft mechanism 4101 can also be achieved through mechanisms such as bearings, dampers, or ratchets. The second rotating shaft mechanism 3112 and the fourth rotating shaft mechanism 4102 are similarly implemented and will not be further described.

[0185] In some embodiments, the vibration direction of the transducer 42 has an outward-pointing direction pointing outside the accommodating space 300. In this outward-pointing direction, the sound-introducing hole 4106 is located above the third rotating shaft mechanism 4101 and the fourth rotating shaft mechanism 4102. By arranging the sound-introducing hole 4106 above the third rotating shaft mechanism 4101 and the fourth rotating shaft mechanism 4102, it is possible to reduce the obstruction of the sound-introducing hole 4106 by the third rotating shaft mechanism 4101 and the fourth rotating shaft mechanism 4102. During the rotation of the movement housing 41 relative to the main housing 31, the sound-introducing hole 4106 can be kept exposed, allowing the sound waves transmitted by the sound-introducing hole 4106 to be directly transmitted to the outside world.

[0186] In some embodiments, the number of the sound-introducing holes 4106 is four, and the four sound-introducing holes 4106 are located in pairs on opposite sides of the circumferential side wall 412. By providing a plurality of sound-introducing holes 4106 on the circumferential side wall 412 of the movement housing 41, the sound waves generated by the transducer device 42 can be transmitted to the outside world along a plurality of different directions, and the effect of improving sound leakage of the sound-introducing holes 4106 can be optimized. Among them, the third rotating shaft mechanism 4101 or the fourth rotating shaft mechanism 4102 is located between the two sound-introducing holes 4106 on the same side in the circumferential direction. In other words, on the movement housing 41, the sound-introducing holes 4106 and the third rotating shaft mechanism 4101 or the fourth rotating shaft mechanism 4102 are staggered, so that the sound emission of the sound-introducing holes 4106 and the rotation of the third rotating shaft mechanism 4101 and the fourth rotating shaft mechanism 4102 do not interfere with each other, so as to improve the reliability of the use of the speaker assembly 3.

[0187] In some embodiments, the main housing 31 includes a bottom wall 311 and a peripheral side wall 312 connected to the bottom wall 311 to form the aforementioned accommodation space 300. The bone conduction speaker 40 includes a vibration plate 424 and a first vibration plate 45. The transducer 42 includes a bracket 421, which can be used to wind a coil and support and maintain the coil's shape. When the transducer 42 is in operation, the coil drives the bracket 421 to vibrate under the action of the current and magnetic field. The first vibration plate 45 connects the bracket 421 and the movement housing 41 to elastically suspend the transducer 42 within the installation space 410. During the vibration of the bracket 421, the first vibration plate 45 can attenuate the vibration transmitted from the bracket 421 to the movement housing 41, thereby reducing sound leakage. The bracket 421 is plugged into the vibration plate 424 along the spacing between the bracket 421 and the bottom wall 311. Vibration of the bracket 421 drives the vibration plate 424 to vibrate, and the vibration plate 424 can transmit the vibration to the face.

[0188] Furthermore, in conjunction with Figures 22 and 23, the bottom wall 411 is provided with a through hole 4110 arranged opposite to the bracket 421, and the through hole 4110 connects the installation space 410 and the accommodating space 300. The through hole 4110 is arranged to allow a supporting jig to be inserted from the through hole 4110 into the installation space 410 and support the bracket 421 when the bracket 421 is located in the installation space 410. The transducer device 42 of the present application is suspended in the installation space 410 through the first vibration transmission plate 45. During the assembly process, in order to reduce the unexpected deformation of the first vibration transmission plate 45, it is necessary to first place the transducer device 42 in the installation space 410, and then connect the first vibration transmission plate 45 to the bracket 421 and the movement housing 41 respectively. Before the first vibration transmission plate 45 is installed, the transducer device 42 requires additional jig support so that the transducer device 42 can be located in the ideal assembly position. By providing a through hole 4110 in the bottom wall 411 to pass a jig through, it is possible to support the bracket 421 when the first vibration transmitting plate 45 is not installed, thereby supporting the transducer device 42 in an ideal position, and then the first vibration transmitting plate 45 is connected to the bracket 421 and the movement housing 41. After the first vibration transmitting plate 45 is connected to the bracket 421 and the movement housing 41, the transducer device 42 can be elastically suspended in the installation space 410, and then the jig can be withdrawn from the through hole 4110. The above method can facilitate the assembly of the transducer device 42 and the first vibration transmitting plate 45, and can improve the success rate of assembly. On the other hand, the through hole 4110 can connect the installation space 410 with the accommodating space 300 or the outside world, which can further assist the sound-inducing hole 4106 in emitting sound, and can also reduce sound leakage.

[0189] In some embodiments, when observed along the vibration direction of the transducer device 42, the bone conduction speaker 40 has a long axis direction and a short axis direction, and the size of the bone conduction speaker 40 along the long axis direction is larger than the size of the bone conduction speaker 40 along the long axis direction. Such a setting can facilitate the adaptation of the bone conduction speaker 40 to the human face, and can increase the vibration transmission area while making the volume of the bone conduction speaker 40 not too large, thereby improving the wearing comfort. Furthermore, the number of through holes 4110 is two, and the two through holes 4110 are spaced apart along the long axis direction. The two through holes 4110 are spaced apart in the long axis direction, which can facilitate the simultaneous insertion of the jig, thereby jointly supporting the bracket 421, which is conducive to further improving the success rate of assembly.

[0190] In some embodiments, referring to Figures 22 and 23 , the bottom wall 411 is further provided with a mounting hole 4111 adjacent to the inner surface of the peripheral side wall 412, spaced apart from the through hole 4110. The mounting hole 4111 connects the installation space 410 with the accommodating space 300. The mounting hole 4111 is configured to allow the acoustic barrier mesh to be inserted through the mounting hole 4111 into the installation space 410, conforming to the inner surface of the peripheral side wall 412 and covering the sound-introducing hole 4106. In other embodiments, the bottom wall 411 may not be provided with the aforementioned mounting hole 4111, and the acoustic barrier mesh may be inserted into the movement housing 41 through the open end 413 of the movement housing 41, and then installed to cover the sound-introducing hole 4106. Because the sound-introducing hole 4106 is directly connected to the outside world, particles of dust and the like can easily enter the installation space 410 through the sound-introducing hole 4106, thereby affecting the operation of the transducer device 42. The acoustic resistance net allows sound to pass through, and can block particles of dust and the like, and can also regulate the acoustic effect. By arranging the acoustic resistance net in the installation space 410 to cover the sound-introducing hole 4106, the disturbance of external particles of dust to the installation space 410 can be reduced, thereby improving the reliability of the operation of the speaker assembly 3. On the other hand. The mounting hole 4111 can also connect the installation space 410 with the accommodating space 300 or the outside world, and can also help reduce sound leakage. Furthermore, the mounting hole 4111 is arranged corresponding to the sound-introducing hole 4106, and the mounting hole 4111 and the corresponding sound-introducing hole 4106 are close to each other on both sides of the connecting edge of the bottom wall 411 and the peripheral side wall 412. Such an arrangement can facilitate the installation of the acoustic resistance net and improve the success rate of assembly. The acoustic resistance net can, for example, include at least one of a steel mesh and a mesh cloth.

[0191] In some embodiments, the distance between the mounting hole 4111 and the corresponding sound guide hole 4106 in the vibration direction of the bone conduction speaker 40 is 1.5 to 5.5 mm, for example, 2 mm, 2.9 mm, 3.1 mm, 3.3 mm, 3.5 mm, or 4 mm. The appropriate distance between the mounting hole 4111 and the sound guide hole 4106 ensures ease of assembly while also preventing the mounting hole 4111 and the sound guide hole 4106 from being too close together, which could result in insufficient rigidity in the corresponding portion of the movement housing 41.

[0192] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
