[0058] In some embodiments, the bracket may include a fixing portion and a pressing portion. The fixing portion is used to fix the bracket in the first groove. The pressing portion may be arranged at a position on the bracket corresponding to the key adapter hole, and is used to trigger the key corresponding to the key adapter hole. In some embodiments, the fixing portion may be arranged in the first sub-groove section, and the pressing portion may be arranged in the second sub-groove section. In some embodiments, the second groove on the bracket is arranged on the fixing portion. In some embodiments, the bracket may further include a first connecting portion connected between the fixing portion and the pressing portion. In some embodiments, the first connecting portion may be bent and extended to a side away from the shell compared to the fixing portion, and the pressing portion may be bent and extended to a side close to the shell compared to the first connecting portion. In some embodiments, the thickness of the fixing portion in a direction perpendicular to the shell surface of the support assembly 120 may be greater than the thickness of the pressing portion, so that the pressing portion has space to move toward the shell surface of the support assembly 120, so that the key can be triggered. In some embodiments, a key protrusion may be provided on one side of the pressing portion close to the shell for triggering the key. In some embodiments, the first connection portion may be elastic, and when the pressing portion is subjected to pressure, the first connection portion may bend and deform, and the key protrusion may move toward the key adapter hole under the pressure to press and trigger the key. In some embodiments, the size of the pressing portion in a direction parallel to the surface of the housing (e.g., the cross-sectional area) may be smaller than the size of the key adapter hole, so that the pressing portion may move in the key adapter hole under pressure, and further trigger the key corresponding to the key adapter hole.

[0059] In some embodiments, a second connection portion is further provided on the other end of the embedded portion of the bracket away from the pressing portion. In some embodiments, the thickness of the second connection portion may be less than the thickness of the embedded portion. In some embodiments, a third connection portion may also be provided on the end of the bracket close to the third portion (the end of the pressing portion away from the embedded portion), and the third connection portion is used to form a snap connection with the inner surface of the side of the third portion where the bracket is assembled, so as to prevent the end of the bracket from tilting from the first groove.

[0060] In some embodiments, the brackets may also be referred to as brackets 321a and brackets 321b. For more information about the brackets, the second groove, the embedding portion, the pressing portion, the first connecting portion, the second connecting portion, and the third connecting portion, please refer to the description of other parts.

[0061] In some embodiments, the first component may include an auxiliary part. In some embodiments, the auxiliary part may be fitted and mounted on the bracket. In some embodiments, the auxiliary part may be physically connected (e.g., bonded or clamped) to the bracket with a decorative layer. In some embodiments, the auxiliary part may be a sticker, and the sticker is fitted on the bracket. In some embodiments, the sticker may include a surface material, a film layer, an adhesive, and a backing paper. In some embodiments, the surface material may include coated paper, masking paper, transparent polyvinyl chloride, kraft paper, polypropylene, etc. In some embodiments, the film layer may include transparent polyester, translucent polyester, transparent polyvinyl chloride, glossy white polyvinyl chloride, matte white polyvinyl chloride, synthetic paper, etc. In some embodiments, the type of adhesive may include general super-sticky type, general strong-sticky type, refrigerated food strong-sticky type, general re-opening type, and fiber re-opening type. In some embodiments, the backing paper may include white, blue, yellow glassine paper or garlic paper, kraft paper, polyester, coated paper, polyethylene, etc. In some embodiments, the auxiliary part may be a plastic part, and the plastic part is clamped on the bracket. In some embodiments, the auxiliary part and the bracket are integrally formed structural parts. In some embodiments, the bonding strength between the auxiliary part and the bracket is less than the fixing strength between the bracket and the second part. Since the fixing strength between the bracket and the second part is greater, when applying external force to replace the auxiliary part, the bracket will not be separated from the second part due to the excessive fit strength between the bracket and the auxiliary part. In some embodiments, the auxiliary part can extend into the second sub-groove section and the third sub-groove section of the first groove. In some embodiments, the auxiliary part can completely or partially cover the second sub-groove section of the first groove. In some embodiments, the auxiliary part can completely or partially cover the third sub-groove section of the first groove. In some embodiments, the auxiliary part can cover the pit on the third sub-groove section. Since the bracket mainly covers the first sub-groove section and the second sub-groove section, and does not cover the third sub-groove section, the part of the auxiliary part on the third sub-groove section is directly fitted in the third sub-groove section and covers the pit. By applying external force to press the auxiliary part into the pit on the third sub-groove section, due to the small rigidity of the auxiliary part, the end (or edge) of the auxiliary part is tilted from the first groove, and the user or operator can tear off the auxiliary part from the tilted end (or edge) for replacement. In some embodiments, the auxiliary part may also be referred to as auxiliary part 322. For more information about the bonding strength, fixing strength and auxiliary member 322, please refer to the description of other parts, for example, Figure 3 and Figure 5 Detailed description.

[0062] In some embodiments, the support assembly 120 may further include a seal. In some embodiments, the seal may be disposed between the key and the third portion. For example, the seal may be disposed between the key and the third portion and cover the key adapter hole corresponding to the key on the third portion from the inner side of the third portion. For example, the material of the seal may include silicone or rubber. In some embodiments, the seal may include a film.

[0063] In some embodiments, the acoustic device 100 may further include a battery assembly (not shown), which is used to provide electrical energy for the acoustic device 100. In some embodiments, the battery assembly may be disposed in the accommodation space of the first portion of the support assembly 120. In some embodiments, the battery assembly and the movement module 110 may be disposed at the same end of the support assembly 120, or may be disposed at both ends of the support assembly 120. In some embodiments, the battery assembly may be connected to the movement module 110 via a wire. For more information about the battery assembly, please refer to the description of other parts, for example, Figure 5 Description of battery 60.

[0064] It should be noted that the above description of the acoustic device 100 is only for example and illustration, and does not limit the scope of application of the present application. For those skilled in the art, various modifications and changes can be made to the acoustic device 100 under the guidance of the present application. However, these modifications and changes are still within the scope of the present application.

[0065] Figure 2 is a schematic diagram of the structure of an exemplary acoustic device according to some embodiments of the present application. Figure 2 As shown, the acoustic device 200 may include two core modules 210 and a support assembly 220 (also referred to as a support assembly 120). The support assembly 220 may include two ear hook assemblies (i.e., an ear hook assembly 30a and an ear hook assembly 30b) and a back hook assembly 40. The acoustic device 200 may also include an interaction assembly, a control circuit assembly, and a battery assembly ( Figure 2 (not shown). One end of the two ear hook components is respectively connected to the corresponding movement module 210, and the two ends of the rear hanging component 40 are respectively connected to the other end of the two ear hook components away from the movement module 210. In some embodiments, the two ear hook components are used to be hung on the outside of the two ears of the user, and the rear hanging component 40 is used to be wrapped around the back of the user's head or neck, so as to meet the needs of the user wearing the acoustic device 200. In this way, when the acoustic device 200 is in a wearing state, the two movement modules 210 are respectively located on the left and right sides of the user's head; and under the cooperation of the two ear hook components 30 and the rear hanging component 40, the two movement modules 210 can clamp the user's head and contact the user's skin, thereby realizing the transmission of sound based on bone conduction technology.

[0066] In some embodiments, the configurations of the two ear hook assemblies may be the same. For example, both ear hook assemblies may include a first portion, a second portion, and a third portion. Both ear hook assemblies may include an interactive component. For more description of the first portion, the second portion, the third portion, and the interactive component, please refer to Figure 1 As described in this article, the configuration of the earhook assembly may refer to the structure (e.g., shape, size, etc.) of the earhook assembly, the components, and other components installed in and / or on the earhook assembly.

[0067] In some embodiments, the control circuit assembly and the battery assembly can be arranged in the same ear hook assembly 30; in some embodiments, the control circuit assembly and the battery assembly can be arranged in two ear hook assemblies 30 respectively, and the specific structure will be described in detail later. Among them, the control circuit assembly and the battery assembly can be connected through a conductor ( Figure 2 In some embodiments, the acoustic device 200 may include microphones such as microphones and pickups, as well as communication elements such as Bluetooth. The above-mentioned components may be connected to the control circuit assembly and the battery assembly through wires to achieve corresponding functions. In some embodiments, the above-mentioned conductor may be a wire for achieving electrical connection between the various electronic components of the acoustic device 200. In some embodiments, if there are multiple circuits that need to be electrically connected, the conductor may be correspondingly set to multiple strands, and then the above-mentioned conductor may be a multi-strand wire.

[0068] It should be noted that: two core modules 210 are provided, and both core modules 210 can make sounds, mainly to facilitate the acoustic device 200 to achieve stereo sound effects, thereby improving the user's favorability of the acoustic device 200. Therefore, in other application scenarios where the requirements for stereo sound are not particularly high, such as hearing aids for hearing-impaired patients, live broadcast prompts for hosts, etc., the acoustic device 200 can also be provided with only one core module 210.

[0070] like Figure 3 as well as Figure 5 As shown, the ear hook assembly (e.g., ear hook assembly 30a, ear hook assembly 30b) may include an ear hook shell (e.g., ear hook shell 31a, ear hook shell 31b), and the ear hook shell may be referred to as a shell. The ear hook assembly 30a and the ear hook assembly 30b are ear hook assemblies on different sides (right and left). In some implementations, the structures of the ear hook assembly 30a and the ear hook assembly 30b may be mirror-symmetrical structures. The interactive component may be disposed on the ear hook assembly. In some embodiments, the interactive component includes a decorative piece (also referred to as a first component) and a button (also referred to as a second component). The button may be triggered by pressing the decorative piece to realize the function corresponding to the button. In some embodiments, the decorative piece may include a decorative piece 32a and a decorative piece 32b respectively disposed on two ear hook assemblies (i.e., the ear hook assembly 30a and the ear hook assembly 30b), and the decorative piece and the ear hook shell may be connected by one or a combination of assembly methods such as gluing, snap-on, and threaded connection. In some embodiments, the decorative piece may include a decorative piece (e.g., decorative piece 32a or decorative piece 32b) and a button disposed on one of the two ear hook components (i.e., ear hook component 30a and ear hook component 30b) (e.g., ear hook component 30a or ear hook component 30b). In some embodiments, the decorative piece is located on the side of the ear hook shell away from the user's head when the acoustic device 200 is in a wearing state, that is, located on the outside of the acoustic device 200, so that the decorative piece can decorate the ear hook shell, thereby increasing the aesthetic appearance of the acoustic device 200. In some embodiments, the decorative piece can protrude from the ear hook shell or be embedded in the ear hook shell. In some embodiments, the decorative piece can be, but is not limited to, a sticker, a plastic part, a metal part, etc. In some embodiments, a geometric pattern, a cartoon pattern, a logo pattern, etc. can be printed on the side of the decorative piece away from the ear hook shell, and a fluorescent material, a reflective material, etc. can also be coated to achieve a corresponding decorative effect.

[0071] like Figure 3-Figure 6As shown, the ear hook housing may include a fixing portion (e.g., fixing portion 311a, fixing portion 311b, also referred to as the third portion), a transition portion (e.g., transition portion 312a, transition portion 312b, also referred to as the second portion) and a receiving portion (e.g., receiving portion 313a, receiving portion 313b, also referred to as the first portion) connected in sequence. In some embodiments, the fixing portion is used to support the movement module 210, and the matching relationship between the two will be described in detail later. For example, Fig. 9 Detailed description. The accommodating portion includes an accommodating space for accommodating other components or elements of the acoustic device 200, for example, some components in the control circuit assembly (for example, the main control circuit board 50), at least some components of the battery assembly (for example, the battery 60), a microphone (sound input assembly), etc. The transition portion connects the accommodating portion and the fixing portion. In some embodiments, the transition portion is arranged in a bent shape so as to be hung on the outside of the human ear. In some embodiments, the transition portion has a certain elasticity and its shape is adapted to the shape of the human auricle. One end of the accommodating portion away from the fixing portion can be connected to the rear hanging assembly 40 by one or a combination of assembly methods such as gluing, clamping, and threaded connection, so as to facilitate the assembly between the ear hanging assembly and the rear hanging assembly 40. In some embodiments, one end of the accommodating portion is arranged in an open manner so as to be used for placing at least some components (the main control circuit board 50 and the battery 60) in the control circuit assembly and / or the battery assembly. In some embodiments, the ear hook housing may include a sealing cover 314, which is arranged on the open end of the accommodating portion so that the accommodating portion forms a good seal.

[0072] In some embodiments, Figure 3 The housing portion 313a shown can be used to accommodate the main control circuit board 50. Figure 5 The housing portion 313b shown can be used to accommodate the battery 60. Figure 3 The ear hook assembly 30a shown corresponds to the left ear hook of the acoustic device 200. Figure 5 The ear hook assembly 30b shown may correspond to the right ear hook of the acoustic device 200; Figure 3 The ear hook assembly 30a shown corresponds to the right ear hook of the acoustic device 200. Figure 5 The ear hook assembly 30b shown may correspond to the left ear hook of the acoustic device 200. In other words, the main control circuit board 50 and the battery 60 may be respectively arranged in the two ear hook assemblies. Such an arrangement can not only increase the capacity of the battery 60 to improve the endurance of the acoustic device 200, but also balance the weight of the acoustic device 200 to improve the wearing comfort of the acoustic device 200. In some embodiments, the main control circuit board 50 and the battery 60 may be connected via a wire built into the rear hanging assembly 40. The specific structure will be described in detail later. For example, Fig.14 Detailed description.

[0073] In some embodiments, when the receiving portion is used to accommodate the main control circuit board 50 of the control circuit assembly, Figure 3 As shown, buttons can be set on the ear hook component 30a, and the buttons may include a control button 33 and an interface 34 (for example, a TYPE-C (USB) interface). In some embodiments, the control button 33 and / or the interface 34 (for example, a TYPE-C (USB) interface) may be set on the accommodating portion 313a, so that both can be connected to the main control circuit board 50, thereby shortening the wiring distance. In some embodiments, the control button 33 and / or the interface 34 (for example, a TYPE-C (USB) interface) may be partially exposed outside the ear hook shell 31a, so that the user can perform corresponding operations. In this way, the control button 33 can be used to realize functions such as turning the acoustic device 200 on and off, adjusting the volume, and the interface 34 can be used to realize functions such as data transmission and charging. In some embodiments, the ear hook component 30a may also include an indicator light 35. In some embodiments, the indicator light 35 may be set on the accommodating portion 313a, so that the two can be connected to the main control circuit board 50, thereby shortening the wiring distance. In some embodiments, as Figure 3 As shown, the indicator light 35 may be partially exposed outside the ear hook housing 31a. In some embodiments, the indicator light 35 may include an LED light source disposed in the ear hook housing 31a and a light guide ( Figure 3 and Figure 4 In this way, the indicator light 35 can provide prompts when the acoustic device 200 is being charged, the battery is insufficient, or the ambient brightness is low.

[0074] It should be noted that when the acoustic device 200 is in a worn state, the acoustic device 200 will be hung on the outside of the human ear (i.e., the back side). Specifically, the movement module 210 is generally located on the front side of the human ear, and the main control circuit board 50 or the battery 60 is generally located on the back side of the human ear. At this time, the human ear supports the acoustic device 200 as a fulcrum, causing the human ear to bear most of the weight of the acoustic device 200. After wearing the acoustic device 200 for a long time, the user may feel uncomfortable. To this end, the ear hook shell (especially the transition part) can be made of a softer material to improve the wearing comfort of the acoustic device 200. In some embodiments, the material of the ear hook shell can be but not limited to polycarbonate (PC), polyamide (PA), acrylonitrile butadiene styrene (ABS), polystyrene (PS), high impact polystyrene (HIPS), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyurethanes (PU), polyethylene (PE), phenolic resin (PF), urea-formaldehyde resin (UF), melamine-formaldehyde resin (MF), silicone, etc. Further, due to the soft texture of the ear hook shell 31, the ear hook shell 31 has insufficient rigidity and is difficult to maintain its structure under the action of external force, and even has the risk of breaking due to insufficient strength. To this end, the ear hook housing can be built with an elastic member (at least in the transition portion) having a certain strength. Figure 4 (not shown in the figure), the elastic part may include metal wire, fiber wire, rubber wire, etc., so as to improve the strength of the ear hook shell, thereby increasing the reliability of the ear hook shell. Among them, the material of the elastic metal wire can be but is not limited to spring steel, titanium alloy, titanium-nickel alloy, chromium-molybdenum steel, etc. In some embodiments, the ear hook shell can be an elastic insert injection-molded one-piece structural part. When making the ear hook shell, an auxiliary metal wire can be used, and the auxiliary metal wire and the elastic part can be arranged side by side. In some embodiments, the auxiliary metal wire and the elastic part can have substantially the same shape, length, radius of curvature and other structural parameters. An elastic coating is formed on the surface of the auxiliary metal wire and the elastic part by injection molding, and then the auxiliary metal wire is pulled out to obtain an elastic insert injection-molded one-piece structural part.

[0075] In some embodiments, since the movement module 210 is arranged at one end of the ear hook assembly (i.e., the end where the fixing portion is located), the main control circuit board 50 or the battery assembly is arranged at the other end of the ear hook assembly (i.e., the other end where the accommodating portion is located), the movement module 210 is connected to the control circuit assembly (e.g., the main control circuit board 50) and the battery assembly (e.g., Figure 5 When the ear hook shell is connected to the battery 60 in the ear hook, the wire must at least pass through the area where the transition portion is located. In some embodiments, for the aesthetic appearance of the acoustic device 200, the wire will not be exposed outside the ear hook shell, but will be inserted into the ear hook shell so that at least the transition portion covers the wire. However, since the texture of the wire is generally soft, it is more difficult to insert the wire into the ear hook shell. To this end, in some embodiments, the ear hook shell may be provided with a first groove (for example, the first groove 315a, the first groove 315b). The decorative piece (for example, the decorative piece 32a, the decorative piece 32b) may be provided with a second groove on the side facing the first groove, so that when the decorative piece is embedded in and fixed in the first groove, the second groove and the first groove cooperate with each other to form a wiring channel. As Figure 3 as well as Figure 5 As shown, the decorative part may include a bracket (e.g., bracket 321a, bracket 321b) and an auxiliary part (e.g., auxiliary part 322a, auxiliary part 322b). The bracket is arranged in a bent shape corresponding to the transition part, so that when the bracket is embedded in and fixed in the first groove corresponding to the transition part, the bracket cooperates with the first groove on the transition part to form a wiring channel to allow the wire to extend from the movement module 210 through the wiring channel to the accommodating part. In some embodiments, the auxiliary part is embedded in the first groove and is fitted and fixed with the bracket. In some embodiments, the bracket can be a plastic part, a fiber part or a metal part, and can be assembled with the ear hook shell by gluing and / or snapping. In some embodiments, the auxiliary part can be a sticker and can be attached to the bracket by gluing. With such a configuration, when the user wants to change the decorative effect of the decorative part, the user can replace the auxiliary part without removing the decorative part as a whole from the ear hook shell.

[0076] In some embodiments, Figure 4As shown, the ear hook housing 31a is provided with a first groove 315a on the transition portion 312a, the fixing portion 311a, and the accommodating portion 313a. The first groove 315a may include a first sub-groove section 3151a located on the transition portion 312a (also referred to as the second portion), a second sub-groove section 3152a located on the fixing portion 311a (also referred to as the third portion), and a third sub-groove section 3153a located on the accommodating portion 313a (also referred to as the first portion). The depth of the first sub-groove section 3151a is greater than the depth of the second sub-groove section 3152a and the third sub-groove section 3153a, so that the first sub-groove section 3151a is used to accommodate the bracket 321a and realize wiring, while the second sub-groove section 3152a and the third sub-groove section 3153a are mainly used to accommodate the auxiliary component 322a. That is, the auxiliary member 322a may be further extended into the second sub-slot segment 3152a and the third sub-slot segment 3153a in addition to being located in the first sub-slot segment 3151a. In some embodiments, the recess 316a may be disposed in the third sub-slot segment 3153a. Furthermore, the depth of the second sub-groove segment 3152a can be equal to the depth of the third sub-groove segment 3153a. After the bracket 321a is embedded in and fixed to the first sub-groove segment 3151a, the side of the bracket 321a facing away from the first sub-groove segment 3151a (the side on which the auxiliary part 322a is installed) can be roughly flush with the bottom of the second sub-groove segment 3152a and the third sub-groove segment 3153a. When the auxiliary part is installed on the side of the bracket facing away from the first sub-groove segment 3151a and in the second sub-groove segment 3152a and the third sub-groove segment 3153a, the auxiliary part 322a can be flatly attached to the fixing portion 311a, the bracket 321a and the accommodating portion 313a.

[0077] Further, the fit strength (or adhesive strength) between the auxiliary member 322a and the bracket 321a may be less than the fixing strength between the bracket 321a and the transition portion 312a. In some embodiments, the fit strength (or adhesive strength) may be the strength when a load is applied to the fitting portion (e.g., the fitting portion between the auxiliary member 322a and the bracket 321a) to cause it to break or separate. In some embodiments, the fixing strength may be the strength when a load is applied to the connection portion (e.g., the connection portion between the bracket 321a and the transition portion 312a) to cause it to break or separate. In some embodiments, the load types may include tensile strength, bending strength, and shear strength. Among them, when the auxiliary member 322 is glued to the bracket 321a, the fit strength may refer to the bonding strength between the two. The size of the fit strength may mainly depend on the roughness of the surface where the bracket 321a and the auxiliary member 322a fit; and / or, the amount (and / or viscosity) of the colloid between the auxiliary member 322a and the bracket 321a. Furthermore, when the bracket 321a is snap-fitted with the transition portion 312a, the fixing strength may refer to the snap-fitting strength between the two. The fixing strength may mainly depend on the fitting clearance between the bracket 321a and the transition portion 312a; and / or the depth of the snap-fitting between the two. With such a configuration, when the bracket 321a and the ear hook shell 31a are assembled in a snap-fitting manner, the two ends of the auxiliary component 322a may be glued to the accommodating portion 313a and the fixing portion 311a respectively, which may further fix the bracket 321a, and when the auxiliary component 322a is replaced to change the decorative effect of the decorative component 32a, the bracket 321a will not be separated from the transition portion 312a due to the excessive fit strength between the bracket 321a and the auxiliary component 322a.

[0078] In some embodiments, Figure 5 As shown, the ear hook shell 31b is provided with a first groove 315b at least on the transition part 312b, and the first groove 315b can be used for wiring to reduce the difficulty of inserting the wire in the ear hook shell 31b. The first groove 315b can be specifically arranged on the side of the ear hook shell 31b close to the decorative part 32b. At this time, the decorative part 32b can be partially embedded and fixed in the first groove 315b corresponding to the transition part 312b, so as to form a wiring channel ( Figure 3 and Figure 5The first groove 315b is not marked in the figure), thereby allowing the wire to extend from the movement module 210 through the wiring channel to the accommodating portion 313b, so that the wire can connect the movement module 210 with the main control circuit board 50 and the battery 60. In this way, when the wire passes through the first groove 315b and is arranged in the ear hook shell 31b, the decorative part 32b can cover the wire to prevent the wire from being exposed outside the ear hook shell. At this time, the decorative part 32b can not only decorate the ear hook shell 31b, but also shield the wire, so that the decorative part 32b can achieve "one piece and two uses".

[0079] In some embodiments, Figure 5 As shown, a button 36 can be set on the ear hook component 30b, and the ear hook shell 31b is also provided with a button adapter hole 317. Among them, the bracket 321b is assembled and fixed on the outer wall of one side of the ear hook shell 31, and the button 36 is set on the inner wall of one side of the ear hook shell 31b to which the bracket 321b is assembled, and is exposed through the button adapter hole 317; the bracket 321b further extends in a cantilever form to the top of the button 36 exposed through the button adapter hole 317, and can trigger the button 36 under external force. In this way, the acoustic device 200 can be turned on and off, the volume adjustment and other functions can be realized by the button 36 without setting the control key 33; the button 36 and the control key 33 can also be set at the same time, the control key 33 is used to realize the functions of turning on and off the acoustic device 200, the volume adjustment and other functions, and the button 36 is used to realize the functions of play / pause, AI voice wake-up (entering the running state from the sleep state after detecting the set voice command), etc., so as to expand the interactive capabilities of the acoustic device 200.

[0080] In some embodiments, the button adapter hole 317 may be provided in the fixing portion 311b, so that the user can press the button 36 at the fixing portion. At this time, the ear hook assembly may further include a seal 37, which is disposed between the button 36 and the fixing portion and covers the button adapter hole 317 from the inner side of the fixing portion. The material of the seal 37 may be, but is not limited to, silicone, rubber, etc. This arrangement can not only increase the waterproof performance of the fixing portion in the area where the button 36 is located, but also improve the pressing touch of the button 36.

[0081] In some embodiments, when the core module 210 is disposed at one end of the ear hook assembly (i.e., the end where the fixing portion is located) and the battery 60 is disposed at the other end of the ear hook assembly (i.e., the end where the accommodating portion is located), the wire must at least pass through the area where the transition portion is located, so that the core module 210 is connected to the battery 60 through the wire. Figure 5As shown, the ear hook shell 31b is provided with a first groove 315b at least on one side of the fixing portion 311b and the transition portion 312b close to the bracket 321b. The first groove 315b can be used for wiring to reduce the difficulty of inserting the wire into the ear hook shell 31b. Furthermore, one end of the first groove 315b is connected to the button adapter hole 317, so that when the bracket 321b is embedded and fixed in the first groove 315b, the bracket 321b can also cover the button adapter hole 317 to facilitate triggering the button 36. In the above manner, the decorative piece can not only decorate the ear hook shell and shield the wire, but also shield and trigger the button 36, so that the decorative piece can achieve "one piece, four uses".

[0082] In some embodiments, Figure 6 As shown, the first groove 315b can be divided into a first sub-groove section 3151b located on the transition portion 312b and a second sub-groove section 3152b located on the fixed portion 311b. Among them, the depth of the first sub-groove section 3151b is greater than the depth of the second sub-groove section 3152b, so that the first sub-groove section 3151b is used to realize wiring, and the second sub-groove section 3152b and the first sub-groove section 3151b are used together to accommodate the bracket. The key adapter hole 317 can be set in the second sub-groove section 3152b, that is, the projections of the two on the fixed portion 311b at least partially overlap. Further, the first groove 315b can also include a third sub-groove section 3153b located on the accommodating portion 313b, and the third sub-groove section 3153b can also be provided with a pit 316b. Among them, the depth of the second sub-groove section 3152b can be greater than the depth of the third sub-groove section 3153b, so that the third sub-groove section 3153b is mainly used to accommodate the auxiliary component 322b. That is, the auxiliary component 322b can be further extended into the third sub-groove section 3153b in addition to being located in the first sub-groove section 3151b and the second sub-groove section 3152b. At this time, after the bracket is embedded and fixed in the first sub-groove section 3151b, the side of the bracket facing away from the ear hook shell 31b can be roughly flush with the bottom of the third sub-groove section 3153b, so that the auxiliary component can be flatly attached to the fixing portion 311b, the bracket and the accommodating portion 313b; and the bracket can form a cantilever at the corresponding key adapter hole 317 of the second sub-groove section 3152b.

[0083] In some embodiments, Figure 7 As shown, the bracket 321b may be provided with a second groove 3211 on the side facing the first groove 315b, so that when the bracket 321b is embedded in and fixed in the first groove 315b, the second groove 3211 and the first groove 315b cooperate with each other to form a wiring channel. Figure 3 not shown).

[0084] It should be noted that the bracket and the auxiliary part can also be an integrally formed structural part. The material of the bracket and the auxiliary part can be different, and the two can be double-color injection molded, so that the bracket can play a supporting role and the auxiliary part can play a decorative role. In some embodiments, the overall length of the auxiliary part can be greater than or equal to the overall length of the bracket.

[0085] In some embodiments, Figure 4 and Figure 6 As shown, a recess (e.g., recess 316a, recess 316b) may be provided at the bottom of the first groove near the end of the auxiliary part to allow the user to press the auxiliary part into the recess so that the end of the auxiliary part is lifted out of the first groove to facilitate replacement of the auxiliary part.

[0086] In some embodiments, the first groove may be further extended to the accommodating portion, and the pit may be provided on the accommodating portion. The pit is located outside the coverage area of ​​the first groove by the bracket, and the auxiliary part is fixed on the bracket and covers the pit. In some embodiments, the overall length of the auxiliary part may be greater than the overall length of the bracket. The bracket covers the first sub-groove section and the second sub-groove section, and the auxiliary part may cover the bracket and extend to cover the third sub-groove section, so that the appearance of the bracket connection on the ear hook assembly is more beautiful. Since the structures of the ear hook assembly 30a and the ear hook assembly 30b can be mirror-symmetrical, the structures of the first groove 315b, the auxiliary part 322b, and the bracket 321b are also mirror-symmetrical to the structures of the first groove 315a, the auxiliary part 322a, and the bracket 321a, and the relevant contents can refer to the relevant description of the symmetrical structure.

[0087] In some embodiments, Figure 7 as well as Figure 8 As shown, the bracket 321b may include an embedding portion 3212 corresponding to the first sub-slot segment 3151b and a pressing portion 3213 corresponding to the second sub-slot segment 3152b. The thickness of the embedding portion 3212 is greater than the thickness of the pressing portion 3213, so that the embedding portion 3212 is used to realize the assembly between the bracket 321b and the ear hook shell 31b, and the pressing portion 3213 is used to trigger the button 36. Further, when the bracket 321b is provided with a second groove 3211 on a side facing the ear hook shell 31b, the second groove 3211 can be provided on the embedding portion 3212.

[0088] like Figure 7 and Figure 8As shown, the bracket 321b may also include a connecting portion 3214 (i.e., a first connecting portion) connected between the embedding portion 3212 and the pressing portion 3213. In some embodiments, the connecting portion 3214 is bent and extended toward a side away from the ear hook shell 31b compared to the embedding portion 3212, and the pressing portion 3213 is bent and extended toward a side close to the ear hook shell 31b compared to the connecting portion 3214. At this time, the connecting portion 3214 makes the pressing portion 3213 suspended relative to the embedding portion 3212, that is, the pressing portion 3213 is not in contact with the earphone shell 31b when it is not in a pressed state, and the vertical distances from the pressing portion 3213 and the embedding portion 3212 to the ear hook shell 31b are not equal and have a certain difference (for example, Figure 8 The difference may be greater than or equal to the trigger stroke of the button 36, where the trigger stroke is the distance moved when the pressing portion 3213 moves toward the button 36 and triggers the button 36 (for example, Figure 8 Such a configuration can effectively improve the problem that when the user presses one end of the bracket 321b (ie, the pressing portion 3213), the other end of the bracket 321b tilts up.

[0089] In some embodiments, a button protrusion 3215 may be further provided on one side of the pressing portion 3213 close to the ear hook housing, so that when the pressing portion 3213 is pressed by an external force, the button protrusion 3215 can trigger the button 36. The projections of the button protrusion 3215 and the button 36 on the fixed portion along the surface of the ear hook housing 31 at least partially overlap, and when the pressing portion 3213 moves toward the button 36 under the action of pressure and contacts the button 36, the effective area (for example, Figure 8 s) is smaller than the effective area of ​​the pressing portion 3213 directly contacting the key 36 when the key protrusion is not provided. Such a configuration can reduce the difficulty of triggering the key 36; especially when a seal 37 is provided between the key 36 and the fixed portion, because the seal 37 needs to deform first to be triggered. Based on the relationship F∝ε·S, when the external force F applied by the user is the same, the smaller the effective area S of the area where the seal 37 needs to deform, the larger the deformation ε of the seal 37, and thus it is easier to trigger the key 36. Obviously, compared with the pressing portion 3213, the key protrusion 3215 can reduce the above-mentioned effective area, thereby making the deformation ε of the seal 37 larger.

[0090] In some embodiments, the bracket may be provided with a stopper 3216 (ie, a third connection portion) at the end portion close to the fixing portion (ie, the end of the pressing portion 3213 away from the embedding portion 3212). Figure 8As shown, the thickness of the stopper 3216 in the direction perpendicular to the button 36 is less than the thickness of the pressing portion 3213. When the pressing portion 3213 is installed in the second sub-slot segment, the stopper 3216 can be used to form a stop with the groove 3154 in the second sub-slot segment in the direction perpendicular to the surface of the ear hook housing 31, so as to prevent the pressing portion on the bracket from being lifted up from the first groove away from the end of the embedding portion 3212 (i.e., the end close to the stopper 3216), especially under the action of external force. In some embodiments, the groove 3154 can be Figure 8 In some embodiments, the groove 3154 may be in a form without a horizontal portion on the top and a vertical wall on the right. Figure 8 As shown, the stopper 3216 can be specifically arranged at one end of the pressing portion 3213 away from the embedding portion 3212. At this time, due to the stopping effect between the stopper 3216 and the fixing portion, after the bracket is deformed under the external force and the button 36 is triggered, the bracket will not be tilted due to excessive elastic recovery.

[0091] In some embodiments, refer again to Figure 3 or Figure 7 , an overlap portion 3217 (i.e., a second connection portion) may be provided at one end of the bracket close to the accommodating portion (i.e., the end thereof away from the pressing portion 3213). In some embodiments, the thickness of the overlap portion 3217 is less than the thickness of the embedding portion 3212, so as to achieve structural overlap by making way for the reinforcing structure of the ear hook housing (specifically located between the transition portion and the accommodating portion) to achieve structural overlap.

[0092] Fig. 9 According to some embodiments of the present application Figure 2 Schematic diagram of the exploded structure of the central movement module.

[0093] like Fig. 9 As shown, the movement module 210 may include a movement shell 21 and a movement 22. In some embodiments, one end of the movement shell 21 is open, and the ear hook shell 31 (specifically, it may be a fixing portion 311) is covered on the open end of the movement shell 21 to form a cavity structure (i.e., an accommodating space) for accommodating the movement 22. At this time, the ear hook shell 31 is equivalent to a cover of the movement shell 21. In this way, compared with the plug-in assembly method of the ear hook structure and the movement structure, the cover assembly method of the ear hook shell 31 and the movement shell 21 in the embodiment of the present application can improve the stress problem of the ear hook structure and the movement structure at the plug-in point, thereby increasing the reliability of the acoustic device 200.

[0094] It should be noted that: Fig. 9The ear hook shell 31 is illustrated in the figure, mainly to facilitate the description of the relative position relationship between the ear hook shell 31 and the movement shell 21, and then to illustrate a possible assembly method between the ear hook shell 31 and the movement shell 21.

[0095] In some embodiments, the movement 22 can be directly or indirectly fixed in the movement housing 21, so that the movement 22 vibrates under the stimulation of the electrical signal and drives the movement housing 21 to vibrate. When the user wears the acoustic device 200, the skin contact area of ​​the movement housing 21 (that is, the bottom wall 211 described later) can contact the user's skin, so that the above-mentioned vibration can be transmitted to the auditory nerve through the human skull, so that the user can hear the sound played by the acoustic device 200. In some embodiments, the movement module 210 may include a movement bracket 23, which is used to fix the movement 22 in the movement housing 21.

[0096] In some embodiments, the movement module 210 may include a bone conduction speaker assembly. The frequency response curve in the frequency range of 500-6000 Hz is particularly critical for bone conduction headphones. In this frequency range, sharp peaks and valleys are not desired; the flatter the frequency response curve, the better the sound quality of the bone conduction headphones.

[0097] Fig.10 is a frequency response curve of an acoustic device according to some embodiments of the present application. Fig.10As shown, the horizontal axis is the frequency of vibration (in Hz), and the vertical axis is the intensity of vibration (in dB); low frequency refers to sounds with a frequency less than 500 Hz, medium frequency refers to sounds within the frequency range of 500-4000 Hz, and high frequency refers to sounds with a frequency greater than 4000 Hz. The high frequency region (the range of frequencies greater than 4000 Hz) has a first high frequency valley V, a first high frequency peak P1, and a second high frequency peak P2. Among them, the first high frequency valley V and the first high frequency peak P1 can be generated by the deformation of the non-skin contact area of ​​the movement housing 21 (that is, the annular peripheral wall 212 described later) at high frequency, and the second high frequency peak P2 can be generated by the deformation of the skin contact area of ​​the movement housing 21 (that is, the bottom wall 211) at high frequency. Generally, the greater the rigidity, the smaller the deformation generated when the structure is subjected to force, and it is also conducive to generating higher frequency resonance. Therefore, in some embodiments, the first high frequency valley V, the first high frequency peak P1, and the second high frequency peak P2 can be moved to a higher frequency region by increasing the rigidity of the movement housing 21. In other words, in order to obtain better sound quality, the rigidity of the movement housing 21 can be as large as possible. To this end, in some embodiments, the material of the movement housing 21 can include a mixture of materials such as polycarbonate, polyamide, acrylonitrile-butadiene-styrene copolymer and glass fiber or carbon fiber. In some embodiments, the material of the movement housing 21 can be a mixture of carbon fiber and polycarbonate in a certain proportion, or a mixture of glass fiber and polycarbonate in a certain proportion, or a mixture of glass fiber and polyamide in a certain proportion. In some other embodiments, the material of the movement housing 21 can be a mixture of carbon fiber, glass fiber and polycarbonate in a certain proportion. Among them, adding different proportions of carbon fiber and / or glass fiber, the elastic modulus of the material is different, and the rigidity of the obtained movement housing 21 is also different. For example, adding 20%-50% of glass fiber to polycarbonate, the elastic modulus of the material can reach 6-8GPa.

[0098] Based on the above detailed description, on the one hand, the ear hook shell 31 (especially the fixing part 311) can be used as a part of the structure of the movement module 210 to form a cavity structure for accommodating the movement 22; on the other hand, in some embodiments, in order to improve the wearing comfort of the acoustic device 200, the ear hook shell 31 is generally made of a softer material, so that the rigidity of the ear hook shell 31 is relatively small. In this way, when the ear hook shell 31 is covered on the movement shell 21 to form a cavity structure for accommodating the movement 22, since the rigidity of the ear hook shell 31 (especially the fixing part 311) is less than that of the movement shell 21, the bone conduction earphone is prone to the undesirable phenomenon of sound leakage, which in turn affects the user's favorability.

[0099] Generally, the resonant frequency of a structure is related to the stiffness of the structure, that is, under the same mass, the greater the stiffness of the structure, the higher its resonant frequency. Among them, the stiffness K of the structure is related to factors such as its material (specifically expressed as elastic modulus) and specific structural form. Generally, the larger the elastic modulus E of the material, the greater the stiffness K of the structure; the larger the thickness t of the structure, the greater the stiffness K of the structure; the smaller the area S of the structure, the greater the stiffness K of the structure. At this time, the above relationship can be simply described by the relationship K∝(E·t) / S. Therefore, one or a combination of methods such as increasing the elastic modulus E of the material, increasing the thickness t of the structure, and reducing the area S of the structure can increase the stiffness K of the structure, thereby increasing the resonant frequency of the structure.

[0100] In some embodiments, the ear hook shell 31 can be made of a softer material (that is, a material with a smaller elastic modulus, such as polycarbonate, polyamide, etc., whose elastic modulus is mostly 2-3GPa), for example, an elastic modulus less than 4GPa, less than 3.5GPa or less than 3GPa, while the movement shell 21 can be made of a harder material (that is, a material with a larger elastic modulus, for example, an elastic modulus greater than 5GPa, greater than 5.5GPa or greater than 6GPa, for example, by adding 20%-50% glass fiber to polycarbonate, the elastic modulus of the material can reach 6-8GPa, etc.). Due to the difference in elastic modulus, the stiffness of the ear hook shell 31 is inconsistent with that of the movement shell 21, and the above-mentioned sound leakage is prone to occur. In addition, after the ear hook shell 31 is connected to the movement shell 21, due to the inconsistent stiffness of the two, it is easy for the structure to resonate at a lower frequency.

[0101] To this end, in some embodiments, when the elastic modulus of the movement housing 21 is greater than the elastic modulus of the ear hook housing 31, the fixing portion 311 of the earphone housing 31 may be provided with a reinforcement structure, so that the difference between the stiffness K1 of the skin contact area of ​​the movement housing 21 and the stiffness K2 of the fixing portion 311 and the stiffness K1 of the skin contact area of ​​the movement housing 21 is less than or equal to 10%. That is, (K1-K2) / K1≤10%, or K2 / K1≥90%. Such a configuration can ensure that the movement housing 21 has a sufficiently large stiffness so that its resonant frequency is located in the high frequency region as high as possible, and can also reduce the stiffness difference between the fixing portion 311 and the movement housing 21 to increase the resonant frequency of the structure and improve the above-mentioned sound leakage.

[0102] For example, Fig.11 According to the embodiment of the present application Fig. 9 A schematic cross-sectional view of an embodiment of a reinforcement structure provided on the middle ear hook housing. Fig.11As shown, the movement housing 21 may include a bottom wall 211 and an annular peripheral wall 212. The bottom wall 211 is the skin contact area of ​​the movement housing 21, and one end of the annular peripheral wall 212 is connected to the bottom wall 211. In other words, the bottom wall 211 is used to contact the user's skin. The fixing portion 311 may include a fixing body 3111 connected to the transition portion 312 and an annular flange 3112 connected to the fixing body 3111 and extending in a direction perpendicular to the plane where the fixing body 3111 is located (i.e., toward the movement housing 21) or inclined at a certain angle to the plane where the fixing body 3111 is located. That is, the angle between the annular flange 3112 and the fixing body 3111 can be 0-90 degrees. The annular flange 3112 and the other end of the annular peripheral wall 212 away from the bottom wall 211 are butted against each other, and the two can be connected by gluing or a combination of gluing and clamping.

[0103] The bottom wall 211 may be rectangular, square, circular, oval, or quasi-elliptical (similar to Fig.12 In some embodiments, the annular circumferential wall 212 may be perpendicular to the bottom wall 211, that is, the area of ​​the opening end of the movement housing 21 is equal to the area of ​​the bottom wall 211; in some embodiments, the annular circumferential wall 212 may also be inclined outwardly at an angle relative to the bottom wall 211 (for example, the inclination angle is less than or equal to 30°), that is, the area of ​​the opening end of the movement housing 21 is greater than the area of ​​the bottom wall 211. In some embodiments, the bottom wall 211 is elliptical and the annular circumferential wall 212 is inclined outwardly at 10° relative to the bottom wall 211 as an example for exemplary description. With such a configuration, under the premise of ensuring a certain degree of wearing comfort (because the bottom wall 211, as the skin contact area of ​​the movement housing 21, will contact the user's skin, its area is not easy to be too small), the area of ​​the bottom wall 211 is reduced, and the resonance frequency of the movement housing 21 can be increased.

[0104] like Fig.11 As shown in (a), the reinforcement structure 318 can be an arc-shaped structure arranged between the fixed body 3111 and the annular flange 3112, that is, the connection between the fixed body 3111 and the annular flange 3112 is chamfered. In some embodiments, the fixed body 3111, the reinforcement structure 318 and the annular flange 3112 can be an integrally formed structure. In some embodiments, the dimension of the annular flange 3112 in the thickness direction of the fixed part 311 (for example, Fig.11In some embodiments, the fixing portion 311 may include a fixing body 3111 and a reinforcement structure 318 of an arc structure, that is, the fixing portion 311 is not provided with an annular flange 3112. In this way, the arc structure reduces the effective area of ​​the fixing portion 311, which can increase the rigidity of the fixing portion 311, thereby reducing the rigidity difference between the fixing portion 311 and the movement housing 21. It should be noted that the size of the arc structure can be reasonably designed according to the rigidity requirement of the fixing portion 311, and is not limited here.

[0105] In some embodiments, Fig.11 As shown in (b), the reinforcement structure 318 can be a thickening layer integrally provided with the fixed body 3111, that is, the fixed body 3111 is thickened. The material of the thickening layer can be the same as the material of the ear hook shell 31, for example, the material of the thickening layer is also any one of polycarbonate, polyamide, and acrylonitrile-butadiene-styrene copolymer. It should be noted that the reinforcement structure 318 can be located on the side of the fixed body 3111 close to the movement shell 21, or on the other side of the fixed body 3111 away from the movement shell 21, and of course, it can also be located on both sides of the fixed body 3111. Furthermore, since the dimension of the annular flange 3112 in the thickness direction of the fixed part 311 is generally small, the annular flange 3112 and the above-mentioned thickening layer can be integrated. At this time, for the fixed part 311, its structure may include the fixed body 3111 and the reinforcement structure 318 provided with the thickening layer. In this way, the thickening layer increases the effective thickness of the fixing portion 311, which can increase the rigidity of the fixing portion 311, thereby reducing the rigidity difference between the fixing portion 311 and the movement housing 21. It should be noted that the size of the thickening layer can be reasonably designed according to the rigidity requirements of the fixing portion 311, and is not limited here.

[0106] In some embodiments, the reinforcement structure 318 can be a metal part. Among them, the material of the metal part can include aluminum alloy, magnesium alloy, titanium alloy, nickel alloy, chrome-molybdenum steel, stainless steel, etc. At this time, the reinforcement structure 318 and the fixing part 311 can be a metal insert injection-molded integrally formed structural part. With such a configuration, the metal part can effectively increase the rigidity of the fixing part 311, thereby reducing the rigidity difference between the fixing part 311 and the movement housing 21. It should be noted that the material, size and other parameters of the above-mentioned metal parts can be reasonably designed according to the rigidity requirements of the fixing part 311, and are not limited here.

[0107] In some embodiments, the reinforcement structure 318 may be an accessory provided on the fixing portion 311. For example, Fig.12 According to the embodiment of the present application Fig. 9A schematic cross-sectional view of an embodiment of a reinforcement structure provided on the middle ear hook housing. Fig.12 As shown, the reinforcement structure 318 may be a reinforcing rib disposed on the fixing portion 311. In some embodiments, the reinforcing rib may be distributed on a side of the fixing portion 311 close to the movement housing 21. In some embodiments, the number of reinforcing ribs may be multiple, and the multiple reinforcing ribs may be arranged as follows: Fig.12 The side-by-side arrangement shown in (a) and (b) or the Fig.12 The plurality of reinforcing ribs may also be arranged in a grid-like manner with the preset reference point on the fixing portion 311 as the center. Fig.12 The radial arrangement shown in (d) in the figure. In some embodiments, the material of the reinforcing ribs can be the same as the material of the ear hook shell 31. For example, the material of the reinforcing ribs is any one of polycarbonate, polyamide, and acrylonitrile-butadiene-styrene copolymer. In this way, compared with the methods of injection molding a metal part on the fixing part 311 or directly thickening the fixing part 311, the reinforcing ribs are arranged on the fixing part 311, which can increase the rigidity of the fixing part 311 while taking into account the weight of the fixing part 311, that is, increase the weight of the fixing part 311 as little as possible.

[0108] In some embodiments, Fig.12 As shown, the fixing portion 311 may have a long axis direction (eg Fig.12 The direction indicated by the dotted line X) and a short axis direction (as shown in Fig.12 The dimension of the fixing portion 311 along the long axis direction may be greater than the dimension along the short axis direction. The following is an exemplary description of the distribution of the reinforcing ribs:

[0109] like Fig.12 As shown in (a), a plurality of reinforcing ribs may be arranged in strips along the long axis and arranged side by side along the short axis. In this case, the reinforcing structure 318 may be regarded as a long-side reinforcement along the fixing portion 311. In some embodiments, the distances between adjacent reinforcing ribs may be the same. In some embodiments, the distances between adjacent reinforcing ribs may be different.

[0110] like Fig.12 As shown in (b), multiple reinforcing ribs may be arranged in strips along the short axis and arranged side by side along the long axis. In this case, the reinforcement structure 318 may be regarded as a short-side reinforcement along the fixing portion 311. In some embodiments, the distances between adjacent reinforcing ribs may be the same. In some embodiments, the distances between adjacent reinforcing ribs may be different.

[0111] like Fig.12As shown in (c), a plurality of reinforcing ribs may be arranged along the long axis direction and the short axis direction to form a grid shape. In this case, the reinforcing structure 318 may be regarded as a cross reinforcement (Cross) of the fixing portion 311.

[0112] like Fig.12 As shown in (d), multiple reinforcing ribs can be arranged along the circumference of the fixing portion 311. The ends of the multiple reinforcing ribs close to each other can be arranged at intervals, and the extension lines of the multiple reinforcing ribs can intersect at a preset reference point (such as Fig.12 In this case, the reinforcement structure 318 can be regarded as a radial reinforcement of the fixing portion 311 .

[0113] After long-term research, the inventors found that under the same conditions (for example, the size and shape of the fixing part 311 are the same, and the distribution shape of the reinforcement structure 318 is the same), when the following size relationship is satisfied between the reinforcing rib and the fixing part 311, the rigidity of the fixing part 311 can be effectively increased, and the weight of the fixing part 311 can be well taken into account. In some embodiments, the ratio between the thickness of the reinforcing rib and the thickness of the fixing part 311 can be within the closed interval [0.8, 1.2]; the width of the reinforcing rib (for example, Fig.12 The ratio of the width d4) in (a) to the thickness of the fixing portion 311 may be within a closed interval [0.4, 0.6], and the ratio of the spacing between the reinforcing ribs to the thickness of the fixing portion 311 may be within a closed interval [1.6, 2.4]. In some embodiments, the thickness of the reinforcing ribs may be the same as the thickness of the fixing portion 311, the width of the reinforcing ribs may be half the thickness of the fixing portion 311, and the spacing between the reinforcing ribs may be twice the thickness of the fixing portion 311. In some embodiments, the thickness of the fixing portion 311 is 0.8 mm, and the thickness, width, and spacing of the reinforcing ribs are 0.8 mm, 0.4 mm, and 1.6 mm, respectively.

[0114] It should be noted that: Fig.11 and Fig.12 The various reinforcement structures shown in the figure can be reasonably combined according to the rigidity requirements of the fixing portion 311, and are not limited here.

[0115] Fig.13 According to the embodiment of the present application Fig.11 and Fig.12 The frequency response curves corresponding to various reinforcement structures. Fig.13As shown, the curve (A+B) can indicate that the material of the fixing part 311 is different from that of the movement housing 21 (for example, the elastic modulus of the former is smaller than that of the latter), and the fixing part 311 has not been improved in structure; the curve (B+B) can indicate that the material of the fixing part 311 is the same as that of the movement housing 21 (for example, the elastic modulus of the two are equal), and the fixing part 311 is similar in structure to the movement housing 21 (for example, the thickness of the two is equal, and the area of ​​the fixing part 311 is also equal to the area of ​​the bottom wall 211). Among them, A can correspond to the fixing part 311, and B can correspond to the bottom wall 211 (that is, the skin contact area of ​​the movement housing 21); (A+B) and (B+B) can correspond to the ear hook housing 31 (specifically, the fixing part 311) covering the movement housing 21 in structure.

[0116] Depend on Fig.13 It can be concluded without a doubt that for structure (A+B), its resonance valley (corresponding to the first high-frequency valley V) appears at a frequency of about 5500 Hz; and for structure (B+B), its resonance valley (corresponding to the first high-frequency valley V) appears at a frequency of about 8400 Hz. Obviously, if structure (A+B) is improved to structure (B+B), that is, the fixing part 311 and the movement housing 21 are made of the same material and have similar structures, the resonance frequency of the structure can be effectively increased.

[0117] Further, for the structure (A+B), the fixing portion 311 is provided with the following Fig.11 The fillet shown in (a) Fig.11 Thickening (b) as shown in Fig.12 Long-Side reinforcement shown in (a) Fig.12 The short-side reinforcement shown in (b) Fig.12 The cross reinforcement (Cross) shown in (c) Fig.12 After the reinforcement structures 318 such as the radial reinforcement (Radiational) shown in (d) are installed, the resonance valleys of (A+B+reinforcement structure) all appear in the frequency range of 5500-8400Hz. That is, providing the reinforcement structure 318 on the fixing portion 311 does help increase the resonant frequency of the structure, that is, providing the reinforcement structure 318 helps to reduce the stiffness difference between the fixing portion 311 and the movement housing 21, and thus helps to improve sound leakage. It should be noted that: the structures of the reinforcement structures 318 are different, and the effect of increasing the resonant frequency is different, that is, the degree of improvement in sound leakage is different. Among them, if the effect of the reinforcement structure 318 on increasing the resonant frequency is ranked from optimal to relatively optimal, the order is: cross reinforcement (such as Fig.12 (c))> Short side reinforcement (such as Fig.12 (b))>Radiation reinforcement (such as Fig.12 Middle (d))> thickening (such as Fig.11 (b))> Long side reinforcement (such as Fig.12 (a))>Chamfer (such as Fig.11 (a)).

[0118] Based on the above detailed description, the movement 22 generates vibrations under the stimulation of the electrical signal, and drives the movement housing 21 to vibrate together; when the user wears the acoustic device 200, the bottom wall 211 (that is, the skin contact area) of the movement housing 21 can contact the user's skin, so that the above vibrations can be transmitted to the auditory nerve through the human skull, and then the user can hear the sound played by the acoustic device 200. At this time, in order to ensure the reliability of the vibration transmission process, at least the movement housing 21 needs to be able to vibrate with the movement 22. Therefore, the movement 22 needs to be fixed in the movement housing 21.

[0119] Fig.14 According to some embodiments of the present application Figure 2 Schematic diagram of the cross-sectional structure of the center rear suspension assembly along the III-III direction. Fig.14 As shown, the rear hanging assembly 40 may include an elastic member 41, a wire 42, and an elastic covering body 43 covering the elastic member 41 and the wire 42. The elastic covering body 43 and the wire 42 are an integral structure formed by extrusion; the elastic covering body 43 further forms a threading channel ( Fig.14 (not marked in the figure), the elastic member 41 is inserted into the threading channel. Preferably, the threading channel is formed during the extrusion molding process. In some embodiments, the material of the elastic member 41 may include fiber, plastic, rubber or metal. In some embodiments, the metal may include spring steel, titanium alloy, titanium-nickel alloy, chrome-molybdenum steel, etc. In some embodiments, the material of the elastic coating 43 may include polycarbonate, polyamide, silicone, rubber, etc., so that the rear hanging component 40 can take into account both the wearing comfort and the structural rigidity.

[0120] It should be noted that: since the elastic member 41 is inserted into the elastic covering body 43 through the threading channel, Fig.14 The area where the middle elastic member 41 is located can be simply regarded as a threading channel in the elastic covering body 43 .

[0121] Furthermore, the diameter of the threading channel in a natural state can be smaller than the diameter of the elastic member 41. Since the elastic coating 43 has a certain elasticity, the elastic member 41 can elastically expand the threading channel during the insertion process of the threading channel so as to be inserted into the threading channel. After the elastic member 41 is inserted into the threading channel, it can be tightly wrapped by the threading channel and remain fixed with the elastic coating 43, so as to avoid the undesirable phenomenon of "sinking" of the rear hanging component 40 due to the excessive gap between the elastic coating 43 and the elastic member 41, especially when the user presses the rear hanging component 40, thereby increasing the structural compactness of the rear hanging component 40.

[0122] In this embodiment, the number of the wires 42 may be at least two. Each wire 42 may include a metal wire and an insulating layer ( Fig.14 The insulating layer is mainly used to achieve electrical insulation between metal wires.

[0123] It should be noted that: Figure 2 , Figure 3 , Figure 5 , Fig. 9 As shown, the main control circuit board 50 and the battery 60 can be respectively arranged in the two ear hook components 30, and Figure 3 and Figure 5 The ear hook assembly 30 shown can correspond to the left ear hook and the right ear hook of the acoustic device 200 respectively, so that not only the main control circuit board 50 and the battery 60 need to be connected via the wire 42 built into the back cover assembly 40, but also the ear hook 30 corresponding to the left ear hook and the right ear hook of the acoustic device 200 respectively. Figure 2 The movement module 210 (specifically, the movement 22) and the button 36 of the middle (left) ear hook assembly 30a need to be further connected to the corresponding Figure 2 The main control circuit board 50 of the middle (right) ear hook assembly 30 is connected, corresponding to Figure 2 The core module 210 of the middle (right) ear hook assembly 30 (specifically, it can be its core 22, microphone, the microphone is used to pick up the sound in the wearer's environment) also needs to be further connected to the corresponding wire 42 built into the back cover assembly 40. Figure 2 The battery 60 of the middle (left) ear hook assembly 30 is connected. Therefore, the wire 42 needs to realize at least the connection of the above three circuits.

[0124] Based on the above detailed description, the rear hanger assembly 40 of some embodiments can be manufactured according to the following process flow:

[0125] 1) Provide an extrusion molding device and a wire.

[0126] On the one hand, the extrusion molding equipment can be added with raw materials for molding the elastic coating body 43. In the extrusion molding process, the raw materials of the elastic coating body 43 at least go through the stages of melting and plasticization, die extrusion, shaping, cooling, and pulling.

[0127] On the other hand, the number of the wires 42 may be at least two, so as to realize the connection between the electronic components in the acoustic device 200. Furthermore, each wire 42 may include a metal wire and an insulating layer covering the metal wire, so as to realize electrical insulation between the metal wires.

[0128] 2) placing the wire in an extrusion molding device so that the raw material of the elastic coating and the wire can obtain a corresponding first semi-finished product during the extrusion molding process.

[0129] The extrusion molding device can pull the wire 42 so that the elastic coating 43 can be coated on the wire 42 during the extrusion molding process. Furthermore, the head portion of the extrusion molding device can be provided with a core so that the elastic coating 43 can simultaneously form the above-mentioned threading channel inside during the extrusion molding process. Therefore, the above-mentioned first semi-finished product can specifically be an integrated structure of the elastic coating 43 and the wire 42, and the elastic coating 43 has a threading channel extending generally along its axial direction.

[0130] 3) According to the use requirements of the rear hanging component, the first semi-finished product is further cut into second semi-finished products with corresponding lengths.

[0131] The actual length of the second semi-finished product may be slightly greater than its use length for the rear hanging component, that is, the second semi-finished product still has a certain margin at this time to facilitate subsequent processing steps.

[0132] 4) Passing the elastic metal wire through the threading channel of the second semi-finished product to obtain a rear hanging assembly.

[0133] Among them, after step 4), not only does the rear hanging component need to be formed into a curved structure with a certain shape so that it can fit the back of the user's head, but it also needs to be processed at both ends of the rear hanging component so that it can be structurally fixedly connected with the ear hanging component and realize the circuit connection between the main control circuit board, battery, button, movement, first and second microphones. Therefore, the rear hanging component obtained in step 4) is essentially only a semi-finished product.

[0134] In the above manner, due to the extrusion molding process, not only a very long semi-finished product (specifically, an integral structure of the elastic coating body 43 and the conductor 42) can be produced at one time, but also a threading channel extending generally along its axial direction can be formed inside the elastic coating body 43 at the same time, and then the semi-finished product is cut into small sections of corresponding lengths for subsequent processing, so that the production efficiency of the rear hanging assembly can be effectively improved.
