[0046] To more clearly illustrate the technical solutions of the embodiments of this application, the following is a brief introduction to the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0047] It should be understood that the terms "system," "device," "unit," and / or "module" used herein are a method for distinguishing different components, elements, parts, portions, or assemblies at different levels. However, if other terms can achieve the same purpose, the terms may be replaced by other expressions.

[0048] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0049] The embodiments of this specification describe a sound-generating device, which includes at least a housing assembly. In some embodiments, the housing assembly may include a housing and a seal. The housing is provided with a socket, which extends through a sidewall of one side of the housing. The seal is used to insert and seal the socket. The socket includes at least one hole wall segment arranged along the insertion direction of the seal. The seal engages with the at least one hole wall segment to achieve waterproof and dustproof performance for the housing assembly. In some embodiments, the cross-sectional area of ​​at least a portion of the structure of the at least one hole wall segment gradually increases along the insertion direction on a reference section perpendicular to the insertion direction of the seal. The seal can form an elastic abutment with at least a portion of the structure of the hole wall segment, not only sealing the socket to increase the waterproof and dustproof performance of the housing assembly, but also being stopped by the at least portion of the structure in the opposite direction of its insertion direction, thereby preventing the seal from withdrawing from the socket due to elastic recovery.

[0050] In some embodiments, the sound-generating device may include a charging component. The charging component may include an interface, a processing chip, a battery management module, and a battery. The interface may include at least one charging pin and at least one programming pin. The interface may implement a charging function via the charging pin and a programming function via the programming pin, so that the interface can simultaneously implement the charging and programming functions of the sound-generating device, eliminating the need for a separate charging interface, thereby reducing costs.

[0051] In some embodiments, the sound-generating device may include a hearing aid, a listening bracelet, headphones (e.g., bone conduction headphones, air conduction headphones), a speaker, smart glasses, a mobile phone, a computer, or other devices with acoustic output capabilities. For example, the sound-generating device is a headphone. In some embodiments, the sound-generating device can be worn on the user's head or other parts (e.g., the neck, shoulders, etc.) through a fixed structure (e.g., an ear hook) to provide audio information to the user. In some embodiments, the sound-generating device can also be combined with other wearable devices (e.g., a smart helmet, glasses, etc.) to be worn on the user's head or other parts. In some embodiments, the sound-generating device may be a bone conduction headphone. Bone conduction headphones can be close to but not block the user's ears, allowing the user to clearly hear the sound played by the sound-generating device while better perceiving external sound information. Bone conduction headphones can convert audio signals into mechanical vibrations of different frequencies, using human bones or muscles as a medium for transmitting mechanical vibrations, and then transmitting sound waves to the auditory nerve, so that the user can receive sound without passing through the external auditory canal and eardrum of the ear. In some embodiments, the sound-generating device may be an air conduction headphone. Air conduction headphones can be placed close to the user's ears without blocking them, allowing the user to clearly hear the sound produced by the sound-generating device while also better perceiving external sound information. Air conduction headphones convert audio signals into sound signals of different frequencies, using air as the medium, and then receive the sound through the user's external auditory canal and eardrum.

[0052] In some embodiments, the sound-emitting device may be a single-sided suspension structure or a double-sided suspension structure. A single-sided suspension structure refers to a structure that can be suspended on one side of a user's head (e.g., ear, face). For example, when the sound-emitting device is a single-sided suspension structure, the sound-emitting device can be suspended on the user's left or right ear. A double-sided suspension structure refers to a structure that can be suspended on both sides of a user's head (e.g., ear, face). For example, when the sound-emitting device is a double-sided suspension structure, the sound-emitting device can be suspended on the user's left and right ears. In some embodiments, the sound-emitting device may include at least one movement and at least one housing assembly, wherein each movement may be connected to a housing assembly, and the housing assembly may fix the sound-emitting device to a certain part of the user. For example, the housing assembly may be hung near the user's ear. In some embodiments, the housing assembly may be a housing structure having a shape that fits the human ear, such as a ring, an ellipse, a polygon (regular or irregular), a U-shape, a V-shape, or a semicircle, so that the housing assembly can be directly hung near the user's ear. In some embodiments, the sound-generating device may further include one or more suspension components, which may be connected to at least one housing component to secure the sound-generating device to the user's head or other body part. For ease of description, the following uses a bone conduction headset with a double-sided suspension structure as an example. Figure 1 Schematic diagram of the structure of the sound-generating device according to some embodiments of the present application. Figure 1 As shown, the sound generating device 10 may include two cores 20, two housing components 30 and a suspension component 40. One end of each housing component 30 may be connected to a corresponding core 20, and both ends of the suspension component 40 are respectively connected to the other ends of the two housing components 30 away from the core 20.

[0053] In some embodiments, each shell component 30 can be curved so that it can be hung on the user's ear. The suspension component 40 can also be curved so that it can be placed around the back of the user's head to meet the user's use requirements of wearing the sound-emitting device 10. When the sound-emitting device 10 is in the worn state, the two movements 20 are respectively located on the left and right sides of the user's head. With the cooperation of the two shell components 30 and the suspension component 40, the two movements 20 can clamp the user's head and contact the user's skin, thereby realizing sound transmission based on bone conduction technology.

[0054] It should be noted that to achieve stereo sound effects, the sound-generating device 10 may include two movement 20, both of which can generate sound, to improve the acoustic performance of the sound-generating device 10. In other application scenarios where stereo sound is not particularly demanding, such as hearing aids for hearing-impaired patients and live teleprompters (for hosts), the sound-generating device 10 may also be provided with only one movement 20.

[0055] Figure 2 FIG. 1 is a schematic diagram of an exploded structure of the housing assembly 30 according to some embodiments of the present application. Figure 2 As shown, in some embodiments, the sound-generating device 10 may further include a mainboard 50 and a battery (not shown). The mainboard 50 and the battery may be electrically connected to the two movements 20 via corresponding conductors. The mainboard 50 may be used to control the sound generation of the movement 20 (e.g., converting electrical signals into mechanical vibrations). The battery may be used to provide power to one or more components of the sound-generating device 10 (e.g., the two movements 20).

[0056] In some embodiments, the motherboard 50 and the battery can be respectively disposed in two housing assemblies 30. For example, the motherboard 50 and the battery can be respectively disposed in two housings 31 (eg, Figure 2 Such a configuration not only increases the capacity of the battery to improve the endurance of the sound-generating device 10, but also balances the weight of the sound-generating device 10 to improve the wearing comfort of the sound-generating device 10.

[0057] In some embodiments, when the sound-emitting device 10 is in a worn state, the sound-emitting device 10 will be hung on the outside of the human ear. Specifically, the movement 20 can be located on the front side of the human ear, and the main board 50 or the battery can be located on the back side of the human ear. The human ear serves as a fulcrum to support the sound-emitting device 10, causing the human ear to bear most of the weight of the sound-emitting device 10. After the user wears the sound-emitting device 10 for a long time, it may cause discomfort. To this end, the contact part between the shell assembly 30 and the human ear (for example, Figure 2 The shell 31 shown, especially the bent transition portion 312 , can be made of a softer material to improve the wearing comfort of the sound-generating device 10 .

[0058] In some embodiments, the sound generating device 10 may include a charging component (e.g., Figure 10 The charging assembly 60 shown in FIG. 3 is shown in FIG. 3 . The charging assembly can be disposed in the housing assembly 30. The charging assembly can be used to charge the sound emitting device 10. In some embodiments, the charging assembly can be used to transmit data from the sound emitting device 10. For a detailed description of the charging assembly 60, see Figure 10 , I will not go into details here.

[0059] In some embodiments, the sound-emitting device 10 may include microphones, pickups, speakers, and other microphones. In some embodiments, the sound-emitting device 10 may include communication devices, such as Bluetooth, near-field communication (NFC), etc. The communication device may be electrically connected to the mainboard 50 and the battery through corresponding conductors to achieve corresponding functions. For example, the communication device may obtain audio signals wirelessly or wiredly. In some embodiments, the pickups, microphones, communication devices, etc. may be arranged in the housing assembly 30, or may be arranged in other components of the sound-emitting device 10. For example, the microphone and speaker may also be arranged in the movement 20.

[0060] like Figure 2 As shown, the housing assembly 30 may include a housing 31 and a seal 38. In some embodiments, the housing assembly 30 may further include one or more of a decorative element 32, a control key 33, an interface 34, an indicator light 35, and the like.

[0061] In some embodiments, the shell 31 may include a fixing portion 311, a bent transition portion 312 and a storage compartment 313. The fixing portion 311 and the storage compartment 313 are respectively connected to the two ends of the transition portion 312. The fixing portion 311 can be used to fix the movement 20. In some embodiments, the fixing portion 311 and the movement 20 can be fixed by one or a combination of assembly methods such as gluing, clamping, and riveting. In some embodiments, the transition portion 312 can be bent so that the shell assembly 30 is hung on the outside of the human ear. In some embodiments, the end of the storage compartment 313 away from the fixing portion 311 can be connected to the suspension assembly 40 by one or a combination of assembly methods such as gluing, clamping, and threaded connection to achieve assembly between the shell assembly 30 and the suspension assembly 40.

[0062] In some embodiments, one end of the storage compartment 313 is open and can be used to accommodate the mainboard 50 charging components or batteries. In some embodiments, the housing 31 may further include a compartment cover 314. The compartment cover 314 is provided on the open end of the storage compartment 313. Figure 3 As shown, Figure 3 yes Figure 2 FIG. 3 is a schematic cross-sectional structural diagram of the housing assembly 30 with III-III as the cutting line. Figure 3 The direction indicated by the arrow B can be roughly regarded as the insertion direction of the sealing member 38. The shell 31 (or the storage bin 313) can be used to form a storage chamber 318, and the bin cover 314 is provided on the open end of the storage bin 313. In some embodiments, a connector 319 can be provided on the shell 31 (or the storage bin 313), and the connector 319 passes through the side wall of one side of the shell 31, that is, the connector 319 is connected to the storage chamber 318. In some embodiments, the connector 319 can be provided on the bin cover 314, and the sealing member 38 is inserted into the bin cover 314 through the connector 319. In this case, the bin cover 314 can be simply regarded as the shell described in this application.

[0063] In some embodiments, the connector 319 may include at least one hole wall segment arranged along the insertion direction of the seal 38. In some embodiments, the cross-sectional area of ​​at least a portion of the structure of the at least one hole wall segment (also referred to as a stop structure) on a reference cross section perpendicular to the insertion direction of the seal 38 gradually increases along the insertion direction. When the seal 38 enters the hole wall segment of the connector 319 along the insertion direction, the seal 38 enters the end of the connector 319 (for example, Figure 4The protruding structure at the insertion portion 381 shown can abut against the stop structure of the hole wall segment, thereby realizing the plug-in fit between the seal 38 and the connector 319. In some embodiments, the stop structure of at least one hole wall segment may include a partial structure of a hole wall segment or a hole wall segment structure among multiple hole wall segments. For example, when the connector 319 includes only one hole wall segment, the portion of the hole wall segment close to the external environment is a cylindrical structure, and the portion of the hole wall segment facing away from the external environment is a reference section perpendicular to the insertion direction of the seal 38, and the cross-sectional area gradually increases along the insertion direction (approximately regarded as a "trumpet shape"). For another example, when the connector 319 includes two or more hole wall segments, the hole wall segment close to the accommodating cavity 318 is a reference section perpendicular to the insertion direction of the seal 38, and the cross-sectional area gradually increases along the insertion direction, and the hole wall segment facing away from the accommodating cavity 318 is a cylindrical structure. Figure 4 yes Figure 3 The schematic diagram of the partially enlarged structure of part A in FIG. Only the hole wall segment including the first hole wall segment and the second hole wall segment is taken as an example. Figure 4 As shown, the socket 319 includes a plug-in direction along the seal 38 (as shown in FIG. Figure 4 The first hole wall segment 3191 and the second hole wall segment 3192 are connected in sequence (in the direction indicated by the arrow B in FIG). Figure 4 The angle formed between the second hole wall section 3192 and the first hole wall section 3191 is an obtuse angle, and the second hole wall section 3192 is perpendicular to the reference section of the insertion direction (for example Figure 4 The cross-sectional area on the plane perpendicular to the reference plane gradually increases along the insertion direction, that is, the second hole wall section 3192 can be trumpet-shaped compared to the first hole wall section 3191. Figure 4 As shown, on the reference plane, the angle formed between the second hole wall segment 3192 and the first hole wall segment 3191 is θ. In some embodiments, the angle θ can be greater than or equal to a first angle threshold and less than a second angle threshold. In some embodiments, the first angle threshold and / or the second angle threshold can be determined based on a balance between the waterproof and dustproof requirements of the seal 38 for the housing 31 and the retaining requirement of the housing 31 for the seal 38. For example, 155°≤θ<180°. For another example, 160°≤θ≤170°. For another example, θ=166°.

[0064] In some embodiments, to improve the comfort of the user when wearing the sound-generating device 10, the sidewalls of the housing 31 that come into contact with the user when wearing the device can be made of a softer material. For example, the material of the housing 31 can include one or more of polycarbonate (PC), polyamides (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., or any combination thereof. In some embodiments, due to the relatively soft texture of the housing 31, there is a risk that the housing 31 may lack rigidity and be unable to maintain its structure under external forces, or even lack strength and break. To this end, an elastic metal wire (not shown) may be embedded in the housing 31 (at least in the bent transition portion 312) to improve the strength and reliability of the housing 31. In some embodiments, the elastic metal wire may be made of spring steel, titanium alloy, titanium-nickel alloy, chrome-molybdenum steel, etc. In some embodiments, the housing 31 may include a metal insert injection-molded integral structural component.

[0065] In some embodiments, the decorative part 32 can be assembled with the shell 31 by one or a combination of assembly methods such as gluing, clamping, and riveting. When the sound-emitting device 10 is in a worn state, the decorative part 32 is located on the side of the shell 31 away from the movement 20, that is, on the outside of the sound-emitting device 10. The decorative part 32 is used to decorate the shell 31, thereby increasing the aesthetic appearance of the sound-emitting device 10. In some embodiments, since the mainboard 50 or the battery and the movement 20 are arranged at both ends of the shell 31, the shell 31 can have a wiring groove 315 for passing the conductor at least in the bending transition part 312. At this time, the decorative part 32 can be embedded in the wiring groove 315 to cover the conductor in the wiring groove 315. Such a setting can not only increase the aesthetic appearance of the sound-emitting device 10, but also facilitate the setting of the wiring structure.

[0066] The control key 33 and the interface 34 are electrically connected to the mainboard 50. In some embodiments, the control key 33 and the interface 34 can be arranged in the storage compartment 313 (or the storage cavity 318) to shorten the wiring distance between the mainboard 50. The control key 33 can be partially exposed outside the shell 31 to realize the functions of turning the sound device 10 on and off, adjusting the volume, etc. In some embodiments, the interface 34 can be arranged corresponding to the socket 319, that is, the interface 34 can be connected to the external environment through the socket 319 to realize functions such as data transmission and charging. In some embodiments, the interface 34 may include a TYPE-A interface, a TYPE-B interface, a TYPE-C interface, a USB interface, a Lighting interface, etc. In some embodiments, the interface 34 may include a pogo-PIN component, which can also realize functions such as data transmission and charging. It should be noted that the interface 34 is a partial component in the charging component. For details about the charging component, please refer to this application specification. Figure 10 and its related descriptions.

[0067] The indicator light 35 can be set on the accommodating compartment 313 to facilitate connection with the mainboard 50 and shorten the wiring distance. Figure 2 As shown, the indicator light 35 can be partially exposed outside the shell 31 to prompt the sound device 10 to be charged, low on power, etc.

[0068] The seal 38 can be inserted into and seal the connector 319. Specifically, the seal 38 can be inserted into the housing 313 through the connector 319 to enhance the waterproof and dustproof properties of the housing assembly 30 at this location, particularly when the interface 34 is not in use. In some examples, the seal 38 can be made of a material with variable elasticity. For example, the seal 38 can be made of polytetrafluoroethylene, rubber (e.g., natural rubber, silicone rubber, ethylene propylene rubber, nitrile rubber, fluorinated rubber, etc.), and the like.

[0069] In some embodiments, the seal 38 may include an insertion portion 381 for inserting into the connector 319. The insertion portion 381 may be plugged into and matched with at least one hole wall segment of the connector 319. In some embodiments, the insertion portion 381 may include at least one protruding structure, which may be distributed on the end face or peripheral side of the end of the insertion portion 381 that is inserted into the connector 319. The protruding structure may abut against the at least one hole wall segment when the insertion portion 381 is inserted into the connector 319. For example, the insertion portion 381 may abut against the end hole wall segment of the at least one hole wall segment, thereby achieving sealing of the connector 319. The end hole wall segment refers to the last hole wall segment in the at least one hole wall segment along the insertion direction of the seal 38, for example, Figure 4The second hole wall segment 3192. In some embodiments, the abutment may be elastic abutment. When the at least one protruding structure forms an elastic abutment with the at least one hole wall segment, each protruding structure forming the elastic abutment will undergo a certain degree of elastic compression deformation and adhere closely to the hole wall segment forming the elastic abutment therewith. Only the case where the protruding structure is an annular protrusion is taken as an example. Figure 4 As shown, the insertion portion 381 is provided with an annular protrusion 3811. When the insertion portion 381 is inserted into the socket 319, the annular protrusion 3811 and one of the at least one hole wall segments (for example, Figure 4 The second hole wall segment 3192) forms an elastic abutment. At this time, at least the annular protrusion 3811 will undergo a certain degree of elastic compression deformation, and will be in close contact with the hole wall segment that forms an elastic abutment therewith. In some embodiments, the deformation amount of the elastic compression deformation can be determined based on the waterproof and dustproof requirements of the seal 38 for the shell 31 and its plugging and unplugging requirements. For example, the deformation amount of the elastic compression deformation can be 0.1-0.3mm. For another example, the deformation amount of the elastic compression deformation can be 0.2mm. In some embodiments, as described above, the cross-sectional area of ​​the stop structure of the at least one hole wall segment on the reference section perpendicular to the insertion direction of the seal gradually increases along the insertion direction. The annular protrusion 3811 can form an elastic abutment with the stop structure, so that the seal 38 can not only seal the socket 319 to increase the waterproof and dustproof performance of the housing assembly 30, but also be stopped by the stop structure of the at least one hole wall segment in the opposite direction of its insertion direction, thereby preventing the seal 38 from withdrawing from the socket 319 due to elastic recovery, that is, the seal 38 can be stopped by the housing 31 after being inserted into the socket 319. For example, Figure 4 As shown, the angle formed between the second hole wall section 3192 and the first hole wall section 3191 is an obtuse angle, and the second hole wall section 3192 gradually expands along the insertion direction and is trumpet-shaped compared to the first hole wall section 3191. Therefore, when the annular protrusion 3811 forms an elastic abutment with the second hole wall section 3192, the seal 38 can be stopped by the second hole wall section 3192.

[0070] In some embodiments, the number of the at least one protruding structure can be set based on the number of the at least one hole wall segment. For example, when the at least one hole wall segment includes only one hole wall segment, only one protruding structure that abuts the hole wall segment can be set. For another example, when the at least one hole wall segment includes two or more hole wall segments, one or more protruding structures that abut the hole wall segment can be set. For another example, multiple protruding structures can be arranged side by side in the insertion direction of the seal 38, and at least one protruding structure can form an elastic abutment with the second hole wall segment 3192. For another example, two protruding structures are provided side by side on the insertion portion 381, one of which forms an elastic abutment with the second hole wall segment 3192, and the other protruding structure forms an elastic abutment with the first hole wall segment 3191, so as to increase the waterproof and dustproof effect of the seal 38 on the housing 31. It should be noted that the protruding structure is not limited to the above-mentioned annular protrusion 3811, and the shape of the protruding structure can be adaptively adjusted according to the shape of the hole wall segment.

[0071] It should be noted that: after the insertion portion 381 is removed from the socket 319, the interface 34 ( Figure 2 (shown in the figure) is exposed through the socket 319 so that the sound device 10 can realize functions such as data transmission and charging through the interface 34.

[0072] Figure 5 According to some embodiments of this application Figure 3 A schematic cross-sectional view of the middle housing 31; Figure 6 and Figure 7 Schematic diagram of the structure of the seal according to some embodiments of the present application. Figure 5 As shown, in some embodiments, the housing 31 further includes a mounting hole 320. Figure 2 When the seal 38 is in use such as data transmission or charging, that is, after the insertion portion 381 is removed from the connector 319, the seal 38 can be fixed to the housing 31 through the mounting hole 320 to prevent the seal 38 from being completely separated from the housing 31 and falling off.

[0073] In some embodiments, combined Figures 5 to 7 The seal 38 may include an assembly portion 382 that cooperates with the mounting hole 320, wherein the assembly portion 382 is connected to the insertion portion 381. In some embodiments, the insertion portion 381 may be integrally formed and connected to the assembly portion 382 or connected in other ways. The assembly portion 382 and the mounting hole 320 may be fixedly connected, that is, the assembly portion 382 may be inserted into the mounting hole 320 and fixed to the housing 31. In some embodiments, the fixed connection method between the assembly portion 382 and the mounting hole 320 may include one or more of clamping, bonding, welding, bolt and screw hole connection, etc.

[0074] like Figure 6 and Figure 7 As shown, the seal 38 includes a connecting portion 383 connecting the insertion portion 381 and the assembly portion 382. The insertion portion 381 and the assembly portion 382 are located on the same side of the connecting portion 383. In some embodiments, the connecting portion 383 may be provided with a thinning structure 3831, so that the average thickness of the connecting portion 383 at the thinning structure 3831 is less than the average thickness of other portions of the connecting portion 383. In some embodiments, the thinning structure 3831 may be located between the insertion portion 381 and the assembly portion 382, ​​so that the insertion portion 381 can be bent relative to the assembly portion 382 via the thinning structure 3831, thereby facilitating the user's removal of the insertion portion 381 from the connector 319. As an example, the thinning structure 3831 may be located on the same side of the connecting portion 383 as the insertion portion 381 and the assembly portion 382. This makes the thinning structure 3831 invisible after the seal 38 is inserted into the connector 319, thereby enhancing the consistency of the seal 38's appearance and structure. In some embodiments, the thinning structure 3831, the insertion portion 381, and the assembly portion 382 can be located on different surfaces of the connection portion 383. In some embodiments, the average thickness of the connection portion 383 at the thinning structure 3831 can be approximately the same as the average thickness of the rest of the connection portion 383. In this case, the insertion portion 381 can be bent relative to the assembly portion 382 by changing the material of the connection portion 383 at the thinning structure 3831. For example, the material of the connection portion 383 at the thinning structure 3831 can be elastic, while the rest of the connection portion 383 can be rigid. In this case, the thinning structure 3831 can be used to bend the insertion portion 381 relative to the assembly portion 382. In some embodiments, a cavity can be provided in the connection portion 383 between the insertion portion 381 and the assembly portion 382 to achieve the function of the thinning structure 3831. In some embodiments, there can be one or more thinning structures 3831. For example, multiple thinning structures 3831 can be arranged in an array or in an uneven arrangement.

[0075] As an example, Figure 6 and Figure 7As shown, the assembly portion 382 may include a connecting section 3821, a stop section 3822, and a guide section 3823 that are sequentially connected (e.g., integrally connected). The connecting section 3821 is connected to the connecting section 383, and the stop section 3822 protrudes from the connecting section 3821 and the guide section 3823. In some embodiments, the length of the connecting section 3821 may be approximately equal to the thickness of the housing 31 at the mounting hole 320, and the diameter of the connecting section 3821 may be slightly smaller than the aperture of the mounting hole 320, so that the assembly portion 382 is mainly inserted into the mounting hole 320 in a one-way manner. After the assembly portion 382 is inserted into the mounting hole 320, the stop section 3822 and the connecting section 383 are respectively located on opposite sides of the housing 31 to prevent the assembly portion 382 from falling out of the mounting hole 320, so that the assembly portion 382 is fixed to the housing 31 by a snap-fit. In some embodiments, the portion of the assembly portion 382 that contacts the housing 31 may be coated with a colloid, which can not only increase the connection reliability between the two, but also increase the waterproof and dustproof performance of the housing 31 at the mounting hole 320. In other words, the assembly portion 382 can always maintain a relatively fixed assembly relationship with the housing 31 and extend from the accommodating cavity 318 to the outside of the housing 31. In some embodiments, the assembly portion 382 can be a light-transmitting member, for example, its material can be polycarbonate or polyamide, and can be connected to the indicator light 35 ( Figure 2 ) is provided to guide the light emitted by the indicator light 35 to the outside of the housing 31, so that the indicator light can prompt when the sound device 10 is charging, low on power, etc. At this time, the indicator light 35 is set in the accommodating cavity 318 and is not visible from the outside of the housing 31. Compared with Figure 2 In the structure shown, the indicator light 35 is exposed outside the housing 31 , so the housing 31 may be provided with one less through-hole structure corresponding to the indicator light 35 , which is beneficial to improving the waterproof and dustproof performance of the housing 31 .

[0076] In some embodiments, the materials of the assembly portion 382 and the insertion portion 381 can be the same or different. When the materials of the assembly portion 382 and the insertion portion 381 are different, the light transmittance of the assembly portion 382 to light can be greater than the light transmittance of the insertion portion 381 to light, so that the light emitted by the indicator light 35 is guided as much as possible by the assembly portion 382 to the outside of the housing 31, and the light guided by the assembly portion 382 is prevented from "leaking" to the insertion portion 381. When the materials of the assembly portion 382 and the insertion portion 381 are the same, a light blocking member (shown in the figures) can be further provided between the assembly portion 382 and the insertion portion 381, and the light transmittance of the light blocking member to light is less than the light transmittance of the assembly portion 382 to light, which can also allow the light emitted by the indicator light 35 to be guided as much as possible by the assembly portion 382 to the outside of the housing 31, and the light guided by the assembly portion 382 is prevented from being guided to the outside of the housing 31 through the insertion portion 381. In some embodiments, the light blocking member can be provided at the thinning structure 3831. Furthermore, the connecting portion 383 between the fitting portion 382 and the inserting portion 381 may be replaced with the aforementioned light blocking member.

[0077] It should be noted that guide section 3823 may primarily function during the assembly process of seal 38 and housing 31. For example, guide section 3823 may first be inserted through mounting hole 320, and then force applied to guide section 3823 may be applied to pull stop section 3822 through mounting hole 320. Therefore, guide section 3823 may be removed after assembly of seal 38 and housing 31, saving space in accommodating cavity 318 and facilitating the installation of other components. Based on this, indicator light 35 may also be aligned with and in contact with the end of stop section 3822 facing away from connecting section 3821, thereby shortening the distance that light emitted by indicator light 35 travels to the exterior of housing 31, thereby reducing light loss.

[0078] Combine Figures 5 to 7 In some embodiments, a groove 321 may be further provided on the housing 31 (specifically, the accommodating chamber 313), and the connector hole 319 and the mounting hole 320 are connected to the bottom of the groove 321. Specifically, in the insertion direction of the seal 38, the groove 321 is located on the side of the first hole wall segment of the at least one hole wall segment facing away from the end hole wall segment, for example, the side of the first hole wall segment 3191 facing away from the second hole wall segment 3192. With this arrangement, when the insertion portion 381 is inserted into the connector hole 319, the connecting portion 383 is stopped by the bottom of the groove 321, thereby preventing the seal 38 from being "over-plugged". In some embodiments, after the insertion portion 381 is inserted into the connector hole 319, the connecting portion 383 can be accommodated in the groove 321. At this time, the connecting portion 383 can be flush with the accommodating chamber 313.

[0079] exist Figure 6 and Figure 7After the seal 38 is assembled with the housing 31, when the user removes the insertion portion 381 from the connector 319, the insertion portion 381 can move relative to the assembly portion 382 via the thinning structure 3831. That is, the free end of the insertion portion 381 (the side away from the connecting portion 383) away from the corner of the assembly portion 382 moves in an arc relative to the assembly portion 382. During this process, the free end of the insertion portion 381 away from the corner of the assembly portion 382 may cause structural interference with the housing 31, especially when the length of the insertion portion 381 (that is, the depth of the insertion portion 381 inserted into the connector 319) is large. Accordingly, when the user inserts the insertion portion 381 into the connector 319, the free end of the insertion portion 381 away from the corner of the assembly portion 382 may also cause structural interference with the housing 31. When inserting or removing the insertion portion 381 from the connector 319, the free end of the insertion portion 381, away from the corner of the assembly portion 382, ​​interferes with the housing 31, causing time and effort for the user. To address this issue, the free end of the insertion portion 381 can be provided with a relief structure. This relief structure is used to reduce interference between the free end of the insertion portion 381, away from the corner of the assembly portion 382, ​​and the housing 31 during insertion or removal of the insertion portion 381 from the connector 319. In some embodiments, the relief structure can be provided at a corner away from the assembly portion 382. Figure 8 and Figure 9 Schematic diagram of the structure of the sealing member 38 according to some embodiments of the present application. Figure 8 As shown, in some embodiments, the avoidance structure 3812 can be a cut corner. The cut corner can be set at the corner of the free end of the insertion portion 381 away from the assembly portion 382. Figure 9 As shown, in some embodiments, the avoidance structure 3812 can be at least one slot. Each of the at least one slot can divide the free end of the insertion portion 381 into at least two parts along the circumferential direction.

[0080] It should be noted that: Figure 8 and Figure 9 As shown, the avoidance structure 3812 does not damage the annular protrusion 3811 as much as possible to ensure the structural integrity of the annular protrusion 3811, thereby ensuring that the seal 38 protects the housing 31 from water and dust.

[0081] In some embodiments, the avoidance structure 3812 can also be set at the corner of the free end of the insertion portion 381 close to the assembly portion 382, ​​so as to make it as convenient as possible for the user to insert the insertion portion 381 into the connector 319 or remove the insertion portion 381 from the connector 319 while ensuring that the seal 38 is waterproof and dustproof to the shell 31.

[0082] In some embodiments, as Figure 8 and Figure 9 As shown, a handle 3832 may be provided at one end of the connecting portion 383 facing away from the assembly portion 382. The average thickness of the connecting portion 383 at the handle 3832 may be less than the average thickness of other portions thereof to facilitate removal of the insertion portion 381 from the connector 319. For example, the handle 3832 may be located on the same side of the connecting portion 383 as the insertion portion 381 and the assembly portion 382. This makes the handle 3832 invisible after the sealing member 38 is inserted into the connector 319, thereby enhancing the consistency of the sealing member 38's appearance and structure.

[0083] When the sound-generating device 10 converts the audio signal into a sound signal (for example, bone conduction sound, air conduction sound), it is necessary to burn data, for example, to burn an application. Usually, the sound-generating device 10 is only provided with an interface for burning data, and the sound-generating device 10 is usually powered by a button battery, which requires frequent battery replacement and is inconvenient to operate. When the button battery is replaced with a rechargeable battery, a corresponding charging interface needs to be provided. The sound-generating device 10 has both a charging interface and an interface for burning data, which increases the production cost of the sound-generating device 10 and is not convenient for the user to operate. Based on the above problems, an embodiment of the present specification provides a charging component, which includes an interface with a charging pin and a burning pin, and simultaneously realizes the charging and burning functions of the sound-generating device 10, so that the charging operation of the sound-generating device 10 is convenient and simple. In addition, the interface can realize the charging function through the charging pin and the burning function through the burning pin. The two functions are realized by one interface, and there is no need to set up a separate charging interface. This can greatly reduce the production cost of the sound-generating device 10 and is also convenient for the user to operate. Figure 10 60 is a schematic diagram of the structure of the charging component 60 according to some embodiments of the present application. The charging component 60 may include an interface 610, a processing chip 620, a battery management module 630 and a battery 640. The charging component 60 may be located in the housing 31 ( Figure 2 As shown in FIG, the position of the interface 610 in the housing 31 can be referred to as Figure 2 Description of interface 34 in.

[0084] In some embodiments, the interface 610 may include at least one charging pin and at least one programming pin. The charging pin is used to power the sound-generating device 10. The programming pin is used to program data to adjust the parameters of the sound-generating device 10 and adapt the sound-generating device 10 to different users. In some embodiments, during the same time period, the interface 610 may only use one of the charging pin or the programming pin to implement the charging function or the programming function. In some embodiments, during the same time period, the interface 610 may use both the charging pin and the programming pin simultaneously to implement the charging function and the programming function.

[0085] The processing chip 620 may be connected to the at least one programming pin. The processing chip 620 programs data via the at least one programming pin. For example, the processing chip 620 programs a program with unique parameters via the at least one programming pin. In some embodiments, the unique parameters may include response frequency, sensitivity, signal-to-noise ratio, transient response, and distortion.

[0086] The battery management module 630 can be configured to control the charging current of the battery 640. The battery 640 can be configured to power the sound-emitting device 10. Specifically, the battery management module 630 can be connected to the interface 610 via the at least one charging pin to receive an input voltage (e.g., 5V), process the input voltage, control the charging current of the battery 640, and thereby charge the battery 640. Exemplarily, the battery management module 630 can include a BQ24045 module or other types of battery management modules. The input voltage received by the battery management module 630 can be 5V.

[0087] Battery 640 can be connected to battery management module 630 and processing chip 620, respectively. When battery 640 is fully charged by battery management module 630, battery 640 stops charging. At the same time, battery 640 outputs voltage to processing chip 620, providing operating voltage for processing chip 620. For example, the output voltage of battery 640 can be 1.2V.

[0088] In some embodiments, battery 640 may include a fast-charging lithium battery. A fast-charging lithium battery can have a maximum current of 3C (C is the total battery capacity), which is 6-15 times higher than that of a conventional rechargeable lithium battery, thereby enabling fast charging of battery 640.

[0089] In some embodiments, the battery management module 630 can control the charging current of the battery 640 based on the voltage of the battery 640. In some embodiments, the battery management module 630 controlling the charging current of the battery 640 based on the voltage of the battery 640 may include: the battery management module 630 obtaining the voltage of the battery 640, and determining whether the voltage of the battery 640 is within a first preset voltage range. If the battery management module 630 detects that the voltage of the battery 640 is within a preset first voltage range (e.g., 0V-4.35V), the charging current is controlled to be the first preset current to achieve rapid charging of the battery 640. At this time, the battery 640 is in a constant current charging stage, and the charging current is the first preset current (e.g., 540mA). During constant-current charging of the battery 640, the voltage of the battery 640 continuously increases. To prevent the voltage of the battery 640 from being excessively high, in some embodiments, the battery management module 630 controls the charging current of the battery 640 based on the voltage of the battery 640, further comprising: the battery management module 630 determining whether the voltage of the battery 640 is within a second preset voltage range (e.g., greater than or equal to 4.35V). If the battery management module 630 detects that the voltage of the battery 640 reaches or exceeds the second preset voltage range, the battery management module 630 may control the charging current to decrease. At this point, the battery 640 is in a constant-voltage charging stage, with the charging voltage being a specific value within the second preset voltage range (e.g., 4.35V). If the battery management module 630 detects that the voltage of the battery 640 is less than the second preset voltage range, the battery management module 630 may control the charging current to the first preset current, so that the battery 640 continues in the constant-current charging stage. During constant voltage charging of the battery 640, the charging current of the battery 640 gradually decreases. That is, when the charging current decreases to a certain value, the battery 640 can be considered fully charged. Furthermore, in some embodiments, the battery management module 630 controls the charging current of the battery 640 based on the voltage of the battery 640, and can also include: determining whether the charging current detected by the battery management module 630 has reached a second preset current range (for example, less than or equal to 27mA). If the charging current reaches or is less than the second preset current range, the battery management module 630 can control the battery 640 to stop charging; if the charging current is greater than the second preset current range, the battery management module 630 can control the battery 640 to continue charging. It should be noted that the first preset voltage range, the second preset voltage range, the first preset current range, and the second preset current range can be set according to the performance of the battery 640. For example, the first preset voltage range may be 0V-4.35V, the second voltage may be 4.35V, the first current may be 540mA, and the second current may be 27mA, that is, the operating voltage of the battery 640 may be 4.35V, and the cut-off current may be 27mA.

[0090] In some embodiments, the charging component 60 may further include a voltage regulator, a power amplifier chip, etc., wherein the voltage regulator and the power amplifier chip can be used as components in the charging component 60, or Figure 2 The components in the main board 50 shown in FIG. The voltage regulator can be used to convert the output voltage of the battery 640 into a regulated voltage. The input end of the voltage regulator can be connected to the output end of the battery 640, and the output end of the voltage regulator can be connected to the input end of the processing chip 620. The input end of the power amplifier chip can be connected to the output end of the processing chip 620 to amplify the audio signal of the processing chip 620. The output end of the power amplifier chip can be connected to the core 20 ( Figure 1 The speaker (also referred to as a loudspeaker) is connected to the speaker (also referred to as a loudspeaker) in the figure, and the speaker is used to output the audio signal amplified and processed by the power amplifier chip to the processing chip 620. In some embodiments, the sound-emitting device 10 may further include at least one microphone, which can be connected to the input terminal of the processing chip 620 to output the received audio signal to the processing chip 620.

[0091] Just as an example, Figure 11 FIG. 7 is an exemplary frame diagram of a sound generating device 70 according to some embodiments of the present application. Figure 10 The charging component 60 shown further includes a voltage regulator 710, an amplifier chip 720, a first speaker 730-1, a second speaker 730-2, a first microphone 740-1 and a second microphone 740-2, and the processing chip 620 in the charging component includes a first processing chip 620-1 and a second processing chip 620-2.

[0092] The input of the voltage regulator 710 is connected to the output of the battery 640, and the output of the voltage regulator 710 is connected to the input of the first processing chip 620-1 and the second processing chip 620-2, respectively. The voltage regulator 710 is configured to convert the output voltage of the battery 640 into a regulated voltage and output it to the first processing chip 620-1 and the second processing chip 620-2 to provide operating voltage for the first processing chip 620-1 and the second processing chip 620-2. The input of the first processing chip 620-1 is connected to the output of the first microphone 740-1. The input of the second processing chip 620-2 is connected to the output of the second microphone 740-2. The outputs of the first processing chip 620-1 and the second processing chip 620-2 are respectively connected to the input of the power amplifier chip 720. The output of the power amplifier chip 720 is respectively connected to the input of the first speaker 730-1 and the second speaker 730-2.

[0093] In some embodiments, the operating voltage of the battery 640 is different from the operating voltage of the processing chip 620 (e.g., the first processing chip 620-1 and the second processing chip 620-2). The output voltage of the battery 640 can be converted into a regulated voltage by the voltage regulator 710. The regulated voltage can be the same as the operating voltage of the processing chip 620. For example, the operating voltage of the battery 640 is 4.35V, that is, the output voltage of the battery 640 is 4.35V, while the operating voltage of the first processing chip 620-1 and the second processing chip 620-2 is 1.2V. The output voltage of the battery 640 cannot be directly used as the operating voltage of the first processing chip 620-1 and the second processing chip 620-2 and needs to be stepped down. Therefore, a voltage regulator 710 is provided at the output end of the battery 640 to step down the output voltage of the battery 640.

[0094] In some embodiments, the voltage regulator 710 may include a low-dropout linear regulator capable of converting an input voltage (e.g., 4.35V) into an appropriate output voltage (e.g., 1.2V) such that the output voltage meets the operating voltage requirements of the first processing chip 620-1 and the second processing chip 620-2. For example, the voltage regulator 710 may include an NCP163AMX120TBG model voltage regulator or other models.

[0095] First microphone 740-1 outputs the received audio signal to first processing chip 620-1. First processing chip 620-1 processes the audio signal using a related algorithm and outputs the processed audio signal to power amplifier chip 720. Power amplifier chip 720 amplifies the audio signal. First speaker 730-1 outputs the audio signal amplified by power amplifier chip 720. For example, power amplifier chip 720 may include a MAX98306 chip or other models of power amplifier chips.

[0096] The second microphone 740-2 outputs the received audio signal to the second processing chip 620-2. The second processing chip 620-2 processes the audio signal with a related algorithm and outputs the processed audio signal to the power amplifier chip 720. The power amplifier chip 720 amplifies the audio signal. The second speaker 730-2 outputs the audio signal amplified by the power amplifier chip 720. It should be noted that the first microphone 740-1 and the second microphone 740-2 can be respectively set at Figure 1The two movements 20 shown, or the housing assembly 30. The first microphone 740-1 and the second microphone 740-2 may include a bone conduction microphone or an air conduction microphone. The bone conduction microphone is used to obtain the vibration signal of the facial muscles of the user when speaking, and convert the vibration signal into an audio signal and output it to the processing chip for processing. At the same time, the sound in the external environment has little effect on the bone conduction microphone, that is, the bone conduction microphone hardly picks up the sound in the external environment. By setting a bone conduction microphone in the sound-emitting device, it can meet the use in specific scenarios (for example, the user is talking in a relatively noisy environment) and improve the quality of the user's call. The air conduction microphone can be used to pick up sounds transmitted through the air (for example, sounds in the external environment, the sound of the user speaking, etc.).

[0097] In some embodiments, the interface 610 may include but is not limited to one of a TYPE-A interface, a TYPE-B interface, a TYPE-C interface, a USB interface, a Lightning interface, etc. In order to facilitate a specific description of the interface 610, the TYPE-C interface is used as an example. Figure 12 This is a wiring definition diagram of the interface 610 shown in some embodiments of the present application. The interface 610 is a TYPE-C interface that is compatible with the pins corresponding to the USB 3.0 protocol. Figure 12 As shown in FIG, the USB 3.0 protocol may include the TX1+ pin, TX1- pin, RX1+ pin, RX1- pin, TX2+ pin, TX2- pin, RX2+ pin, RX2- pin, and VBUS pin. The TX1+ pin is connected to the TX2+ pin to form the TX+ pin. The TX1- pin is connected to the TX2- pin to form the TX- pin. The RX1+ pin is connected to the RX2+ pin to form the RX+ pin. The RX1- pin is connected to the RX2- pin to form the RX- pin.

[0098] Just as an example, Figure 13 is a structural diagram of the interface 610 according to some embodiments of the present application. Figure 12 The TX+ pin, TX- pin, RX+ pin and RX- pin correspond to Figure 13 The SSTXP1 pin, SSTXN1 pin, SSRXP1 pin, and SSRXN1 pin are shown. The VBUS pin corresponds to Figure 13 The interface 610 uses the TX+, TX-, RX+, and RX- pins as programming pins of the TYPE-C interface, and uses the VBUS0 pin as a charging pin of the TYPE-C interface.

[0099] Interface 610 is connected to the first processing chip 620-1 and the second processing chip 620-2, respectively. The programming pins of interface 610 are connected to the I2C interfaces of the first processing chip 620-1 and the second processing chip 620-2, respectively, so that data can be programmed simultaneously on the first processing chip 620-1 and the second processing chip 620-2. Specifically, the I2C interface of the first processing chip 620-1 includes the SCL1 pin and the SAD1 pin, and the I2C interface of the second processing chip 620-2 includes the SCL2 pin and the SAD2 pin. The TX+ pin and TX- pin are connected to the SCL1 pin and the SAD1 pin, respectively, and the RX+ pin and RX- pin are connected to the SCL2 pin and the SAD2 pin, respectively.

[0100] In some embodiments, the processing chip 620 (e.g., E7111 chip) is highly sensitive to static electricity and needs to be treated with anti-static treatment. To this end, the sound-generating device 10 may further include one or more components for anti-static treatment (e.g., TVS tubes (transient voltage suppressors)). For example, Figure 13 As shown, the sound generating device 10 may include a first TVS tube D1, a second TVS tube D2, a third TVS tube D3, a fourth TVS tube D4 and a fifth TVS tube D5. Figure 13 As shown, one end of the first TVS diode D1 is connected to the SCL1 pin, one end of the second TVS diode D2 is connected to the SAD1 pin, one end of the third TVS diode D3 is connected to the SCL2 pin, one end of the fourth TVS diode D4 is connected to the SAD2 pin, and one end of the fifth TVS diode D5 is connected to the VBUS0 pin. The other ends of the first, second, third, fourth, and fifth TVS diodes D1, D2, D3, D4, and D5 are grounded. When a large transient interference voltage or pulse current occurs in a circuit due to lightning or other electrical interference, the TVS diode can quickly switch to a reverse conduction state and clamp the circuit voltage to a required safety level, effectively protecting the delicate components in the electronic circuit from damage. After the interference pulse passes, the TVS diode returns to a reverse blocking state. Because the clamping voltage of the TVS diode during reverse conduction is lower than the maximum withstand voltage of the E7111 chip, it effectively protects the E7111 chip.

[0101] In some embodiments, as Figure 13 As shown, the interface 610 may further include an identification pin CC1 for identifying a functional accessory so that the sound device 10 can be matched and connected with the functional accessory. Optionally, the functional accessory may be an external burning device or the like.

[0102] In some embodiments, as Figure 13As shown, the sound-generating device 10 may further include a pull-down resistor R1, one end of which is connected to the identification pin CC1, and the other end of which is grounded. Exemplarily, the resistance of the pull-down resistor R1 is 5.1 kΩ. By providing the pull-down resistor R1 at one end of the identification pin CC1, this embodiment improves the noise tolerance of the input signal of the sound-generating device 10, while also achieving resistance matching and enhancing anti-interference capabilities.

[0103] According to some embodiments of the present application, by providing an interface 610 including at least one charging pin and at least one programming pin, the charging and programming functions of the sound-generating device 10 can be simultaneously realized, thereby making the charging operation of the sound-generating device 10 convenient and simple. The interface 610 realizes the charging function through the charging pin and the programming function through the programming pin. With a single interface, both functions are realized, eliminating the need for a separate charging interface and reducing costs.
