In some embodiments, the sound generating device may include a hearing aid, a listening bracelet, an earphone (e.g., a bone conduction earphone, a gas conduction earphone), a sound box, smart glasses, a mobile phone, a computer, or other device with acoustic output capability. For example, the sound emitting device is a headset. In some embodiments, the sound generating device may be worn on the head or other part (e.g., neck, shoulder, etc. area) of the user via a structure such as a fixed structure (e.g., an ear hook) to provide audio information to the user. In some embodiments, the sound emitting device may also be combined with other wearable devices (e.g., smart helmets, glasses, etc.) to be worn on the head or other parts of the user. In some embodiments, the sound emitting device may be a bone conduction headset. The bone conduction earphone can be close to but not block the ears of the user, so that the user can hear the sound played by the sound generating device and can better sense the external sound information. The bone conduction earphone can convert an audio signal into mechanical vibration of different frequencies, takes human bones or muscles as a medium for transmitting the mechanical vibration, and then transmits sound waves to auditory nerves, so that a user can receive sound without passing through the external auditory canal and the eardrum of the ear. In some embodiments, the sound generating device may be an air conduction headset. The air conduction earphone can be close to the ear of the user without blocking the ear of the user, so that the user can hear the sound played by the sound generating device and can better sense the external sound information. The air conduction earphone can convert an audio signal into a sound signal with different frequencies, and takes air as a medium, so that the sound is received through the external auditory canal and the eardrum of the ear of a user.

In some embodiments, the sound emitting device may be a single-sided suspension structure or a double-sided suspension structure. A one-sided suspension structure refers to a structure that can be suspended to one side of a user's head portion (e.g., ear, face). For example, when the sound generating device is of a one-sided suspension structure, the sound generating device may be suspended at the left or right ear of the user. A bilateral suspension structure refers to a structure that can be suspended on both sides of a user's head portion (e.g., ear, face). For example, when the sound generating device is a double-side hanging structure, the sound generating device may be hung at the left and right ears of the user. In some embodiments, the sound generator may include at least one cartridge and at least one housing assembly, wherein each cartridge may be coupled to one housing assembly that may secure the sound generator to a portion of a 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 human ear-fitting shape, such as a circular ring, an oval, a polygon (regular or irregular), a U-shape, a V-shape, a semi-circle, so that the housing assembly may be directly hung near the user's ear. In some embodiments, the sound device may further include one or more suspension assemblies, which may be coupled to at least one housing assembly for securing the sound device to a user's head or other location. For convenience of description, the bone conduction headset in which the sound generating device is a double-side suspension structure is exemplified as follows. Fig. 1 is a schematic diagram of a sound generating device according to some embodiments of the present application. As shown in fig. 1, the sound generator 10 may include two movements 20, two housing assemblies 30, and a suspension assembly 40. One end of each housing assembly 30 can be connected to a corresponding movement 20, and both ends of the suspension assembly 40 are respectively connected to the other ends of the two housing assemblies 30 far away from the movement 20.

In some embodiments, each housing assembly 30 may be curved such that it may be hung on a user's ear. The suspension assembly 40 may also be curved so that it can be wrapped around the back of the user's head to meet the user's needs for wearing the sound generator 10. When the sound generating device 10 is worn, the two movements 20 are respectively located on the left side and the right side of the head of the user. Under the cooperation of the two housing assemblies 30 and the suspension assembly 40, the two movements 20 are enabled to clamp the head of the user in contact with the skin of the user, so that sound transmission can be realized based on bone conduction technology.

It should be noted that, in order to realize the stereo sound effect, the sound generating device 10 may include two movements 20, both of which can generate sound, to improve the acoustic performance of the sound generating device 10. In other applications where the stereo requirements are not particularly high, such as hearing assistance, live (presenter) prompting, etc., the sound generating device 10 may be provided with only one movement 20.

Fig. 2 is an exploded view of a housing assembly 30 according to some embodiments of the present application. As shown in fig. 2, in some embodiments, the sound emitting device 10 may further include a main board 50 and a battery (not shown). The motherboard 50 and the battery may be electrically connected to the two cartridges 20 by respective conductors. The main board 50 may be used to control the sound emission (e.g., converting electrical signals into mechanical vibrations) of the movement 20. The battery may be used to provide power to one or more components of the sound generator 10 (e.g., both cartridges 20).

In some embodiments, the motherboard 50 and the battery may be disposed within the two housing assemblies 30, respectively, e.g., the motherboard 50 and the battery may be disposed within the two housings 31 (shown in fig. 2), respectively. So set up, not only can increase the capacity of battery to improve sound generating mechanism 10's duration, can also carry out the equilibrium to sound generating mechanism 10's weight, with the wearing comfort level that improves sound generating mechanism 10.

In some embodiments, the sound generator 10 will hang outside of the human ear when the sound generator 10 is worn. Specifically, the movement 20 may be located on the front side of the human ear, and the main board 50 or the battery may be located on the rear side of the human ear. The human ear acts as a fulcrum to support the sound generator 10 so that the human ear will bear most of the weight of the sound generator 10. The user may feel uncomfortable after wearing the sound emission device 10 for a long time. For this reason, the contact portion of the casing assembly 30 and the human ear (e.g. the casing 31 shown in fig. 2, especially the bending transition portion 312) can be made of a softer material to improve the wearing comfort of the sound emitting device 10.

In some embodiments, the sound emitting device 10 may include a charging assembly (e.g., the charging assembly 60 shown in fig. 10). The charging assembly may be disposed in the housing assembly 30. The charging assembly may be used to charge the sound generator 10. In some embodiments, the charging assembly may be used for data transmission of the sound emitting device 10. For a detailed description of the charging assembly 60, see fig. 10, it is not described herein.

In some embodiments, the sound generating device 10 may include a microphone, horn, or the like. In some embodiments, the sound emitting device 10 may include a communication device, such as bluetooth, Near Field Communication (NFC), or the like. The communication device may be electrically connected to the motherboard 50 and the battery via respective conductors to perform respective functions. For example, the communication device may acquire the audio signal in a wireless or wired manner. In some embodiments, the microphone, communication device, etc. may be disposed in the housing assembly 30, as well as in other components of the sound generating device 10. For example, a microphone and a speaker may be provided in the movement 20.

As shown in fig. 2, 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 decorative pieces 32, control keys 33, interfaces 34, indicator lights 35, and the like.

In some embodiments, the shell 31 may include a fixing portion 311, a bent transition portion 312, and a receiving bin 313. The fixing portion 311 and the accommodating chamber 313 are connected to two ends of the transition portion 312, respectively. The fixing portion 311 may be used to fix the movement 20. In some embodiments, the fixing means of the fixing portion 311 and the movement 20 may be one or a combination of gluing, clipping, riveting, and the like. In some embodiments, the transition portion 312 may be bent to allow the housing assembly 30 to hang outside of the human ear. In some embodiments, an end of the accommodating chamber 313 away from the fixing portion 311 may be connected to the suspension assembly 40 by one or a combination of adhesive bonding, clamping, screwing, and the like, so as to achieve assembly between the housing assembly 30 and the suspension assembly 40.

In some embodiments, one end of the accommodating chamber 313 is open and can be used for accommodating a charging component or a battery of the motherboard 50. In some embodiments, the housing 31 can further include a cartridge body cover 314. The bin body cover 314 covers the open end of the accommodating bin 313. Fig. 3 is a schematic cross-sectional view of the housing assembly 30 of fig. 2, taken along line III-III, as shown in fig. 3. The direction indicated by the arrow B in fig. 3 can be approximately regarded as the plunging direction of the seal 38. The housing 31 (or the accommodating chamber 313) can be used to form an accommodating cavity 318, and the chamber cover 314 covers the open end of the accommodating chamber 313. In some embodiments, a patch jack 319 may be disposed on the housing 31 (or the receiving compartment 313), and the patch jack 319 extends through a side wall of one side of the housing 31, i.e., the patch jack 319 communicates with the receiving cavity 318. In some embodiments, patch apertures 319 can be provided in the cartridge body cover 314 and the seals 38 can be plugged into the cartridge body cover 314 through the patch apertures 319. At this point, the cartridge body cover 314 can be simply considered a housing as described herein.

In some embodiments, the patch jack 319 may include at least one wall segment of the bore disposed in the plugging direction of the seal 38. In some embodiments, at least a portion of the structure (also referred to as a stop structure) of at least one of the aperture wall sections has a cross-sectional area, in a reference cross-section perpendicular to the insertion direction of the seal 38, that gradually increases along the insertion direction. When the sealing member 38 enters the wall section of the plug hole 319 in the plugging direction, the protruding structure at the end of the sealing member 38 entering the plug hole 319 (e.g., the insertion portion 381 shown in fig. 4) may abut against the stop structure of the wall section, thereby achieving the plugging fit of the sealing member 38 with the plug hole 319. In some embodiments, the stop of the at least one aperture wall section may comprise a partial structure of an aperture wall section or an aperture wall section structure of a plurality of aperture wall sections. For example, when the plug bore 319 includes only one bore wall section, the portion of the bore wall section adjacent to the external environment is a cylindrical structure, and the portion of the bore wall section facing away from the external environment is a cross-sectional area of a reference cross-section perpendicular to the plugging direction of the seal 38 that gradually increases along the plugging direction (approximately regarded as "trumpet-shaped"). For another example, when the insertion hole 319 includes two or more hole wall sections, the hole wall section near the accommodation chamber 318 has a cross-sectional area in a reference cross-section perpendicular to the insertion direction of the seal 38, which gradually increases along the insertion direction, and the hole wall section away from the accommodation chamber 318 has a cylindrical structure. Fig. 4 is a partially enlarged structural view of a portion a in fig. 3. By way of example only, where the bore wall segments include a first bore wall segment and a second bore wall segment, as shown in fig. 4, the patch jack 319 includes a first bore wall segment 3191 and a second bore wall segment 3192 connected in series in the insertion direction of the seal 38 (as indicated by arrow B in fig. 4). On a reference plane (e.g., a plane on which the accommodating chamber 313 and the sealing member 38 are located in fig. 4) parallel to the plugging direction, an included angle formed between the second hole wall segment 3192 and the first hole wall segment 3191 is an obtuse angle, and a cross-sectional area of the second hole wall segment 3192 on a reference cross-section (e.g., a plane perpendicular to the reference plane in fig. 4) perpendicular to the plugging direction gradually increases along the plugging direction, i.e., the second hole wall segment 3192 may be flared compared to the first hole wall segment 3191. For example, as shown in fig. 4, the second aperture wall segment 3192 and the first aperture wall segment 3191 form an angle θ with respect to a reference plane. In some embodiments, the included angle θ may 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 may be determined according to a requirement of the housing 31 to protect the housing 31 from water and dust and a requirement of the housing 31 to prevent the sealing member 38 from backing. For example, 155 ≦ θ < 180. As another example, 160 ° ≦ θ ≦ 170 °. For another example, θ is 166 °.

In some embodiments, to improve the comfort of the user wearing the sound emitting device 10, the sidewall of the housing 31 that contacts the user wearing the sound emitting device may be made of a softer material. For example, the material of the housing 31 may include one or more of Polycarbonate (PC), Polyamide (PA), Acrylonitrile Butadiene Styrene (ABS), Polystyrene (PS), High Impact Polystyrene (High Impact Polystyrene, HIPS), Polypropylene (PP), Polyethylene Terephthalate (PET), Polyvinyl Chloride (PVC), Polyurethane (PU), Polyethylene (PE), Phenol Formaldehyde (PF), Urea Formaldehyde (Urea-Formaldehyde, UF), Melamine-Formaldehyde (MF), silicone, or the like, or any combination thereof. In some embodiments, the shell 31 may have insufficient rigidity due to the soft texture of the shell 31, and may have difficulty maintaining its structure under external force, or may even have insufficient strength to break. For this purpose, an elastic wire (not shown) may be disposed in the housing 31 (at least in the bending transition portion 312) to improve the strength of the housing 31 and increase the reliability of the housing 31. In some embodiments, the elastic wire may be made of spring steel, titanium alloy, titanium-nickel alloy, chrome-molybdenum steel, or the like. In some embodiments, the housing 31 may comprise a metal insert molded integral structural member.

In some embodiments, the decoration 32 may be assembled with the housing 31 by one or a combination of gluing, clamping, riveting, and the like. When the sound generating device 10 is in a wearing state, the decoration 32 is located on a side of the casing 31 away from the movement 20, that is, on an outer side of the sound generating device 10, and the casing 31 is decorated by the decoration 32, so that the aesthetic appearance of the sound generating device 10 is enhanced. In some embodiments, since the main board 50 or the battery and the movement 20 are disposed at two ends of the housing 31, the housing 31 may be provided with a wiring groove 315 for passing through a conductor at least at the bending transition portion 312. At this point, the trim piece 32 can be inserted into the routing channel 315, covering the conductors within the routing channel 315. By the arrangement, the appearance aesthetic feeling of the sounding device 10 can be increased, and the wiring structure can be conveniently arranged.

The control keys 33 and the interface 34 are electrically connected to the main board 50. In some embodiments, the control keys 33 and the interface 34 may be disposed in the housing compartment 313 (or the housing cavity 318) to shorten the routing distance with the motherboard 50. The control key 33 may be partially exposed outside the casing 31 to implement the functions of turning on and off the sound generating device 10, adjusting the volume, and the like. In some embodiments, the interface 34 may be disposed corresponding to the patch jack 319, that is, the interface 34 can communicate with the external environment through the patch jack 319, and is used for implementing functions of data transmission, charging and the like. In some embodiments, interface 34 may include a TYPE-A interface, a TYPE-B interface, a TYPE-C interface, a USB interface, a Lighting interface, and the like. In some embodiments, the interface 34 may include a pogo-PIN component, which may also implement data transfer, charging, and the like. It should be noted that the interface 34 is a part of the charging assembly, and reference may be made to fig. 10 and the related description thereof for details of the charging assembly.

The indicator light 35 may be disposed on the accommodating compartment 313 to facilitate connection with the main board 50, so as to shorten the distance of wiring. In some embodiments, as shown in fig. 2, the indicator light 35 may be partially exposed outside the housing 31 to indicate charging, insufficient power, etc. of the sound generating device 10.

The seal 38 may be used to plug and seal the patch hole 319, i.e., the seal 38 can be plugged into the receiving bin 313 via the patch hole 319 to increase the waterproof and dustproof performance of the housing assembly 30 at this point, especially in situations where the interface 34 is not used. In some examples, the seal 38 may be a material having a variable elasticity. For example, the material of the seal 38 may include polytetrafluoroethylene, rubber (e.g., natural rubber, silicone rubber, ethylene propylene rubber, nitrile rubber, fluorinated rubber, etc.), and the like.

In some embodiments, the seal 38 may include an insertion portion 381 for insertion into the patch jack 319. The insertion portion 381 may be mated with at least one wall segment of the patch aperture 319. In some embodiments, the insertion portion 381 may include at least one protrusion structure, which may be distributed at an end surface or a peripheral side of the insertion portion 381 inserted into one end of the patch jack 319, and the protrusion structure may abut against the at least one hole wall section when the insertion portion 381 is inserted into the patch jack 319, for example, the insertion portion 381 may abut against a terminal hole wall section in the at least one hole wall section, thereby achieving sealing of the patch jack 319. The end aperture wall segment refers to the last aperture wall segment in the at least one aperture wall segment in the packing direction of the seal 38, e.g., the second aperture wall segment 3192 depicted in FIG. 4. In some embodiments, the abutment may be a resilient abutment, each resiliently abutting raised formation being resiliently deformed in compression to a degree to abut the aperture wall section with which it is resiliently abutting when the at least one raised formation is resiliently abutting the at least one aperture wall section. Taking only the case where the protrusion structure is an annular protrusion as an example, as shown in fig. 4, the insertion portion 381 is provided with an annular protrusion 3811, and when the insertion portion 381 is plugged into the plug hole 319, the annular protrusion 3811 forms an elastic abutment with one of the at least one hole wall section (e.g., the second hole wall section 3192 shown in fig. 4). At this time, at least the annular projection 3811 is elastically deformed in compression to some extent and is brought into close contact with the wall portion of the hole in elastic abutment therewith. In some embodiments, the deformation amount of the elastic compression deformation may be determined according to the waterproof and dustproof requirements of the sealing member 38 for the shell 31 and the insertion and extraction requirements thereof. For example, the amount of deformation of the elastic compression deformation may be 0.1 to 0.3 mm. For another example, the amount of deformation of the elastic compression deformation may be 0.2 mm. In some embodiments, as previously described, a cross-sectional area of the stop structure of the at least one bulkhead section in a reference cross-section perpendicular to the seal plunging direction increases progressively along the plunging direction. The annular protrusion 3811 may form an elastic abutment with the stopping structure, so that the sealing member 38 may not only seal the docking jack 319 to increase the waterproof and dustproof performance of the housing assembly 30, but also be stopped by the stopping structure of the at least one jack wall section in the direction opposite to the plugging direction, so as to prevent the sealing member 38 from being withdrawn from the docking jack 319 due to elastic recovery, that is, the sealing member 38 can be stopped by the housing 31 after being plugged into the docking jack 319. For example, as shown in fig. 4, an included angle formed between the second hole wall 3192 and the first hole wall 3191 is an obtuse angle, and the second hole wall 3192 gradually expands along the plugging direction to be a horn shape compared to the first hole wall 3191, so that when the annular protrusion 3811 and the second hole wall 3192 are elastically abutted, the sealing member 38 can be stopped by the second hole wall 3192.

In some embodiments, the number of the at least one raised structure may be set based on the number of the at least one aperture wall section. For example, where the at least one aperture wall section comprises only one aperture wall section, only one raised formation may be provided in abutment with the aperture wall section. For another example, where the at least one aperture wall section includes two or more aperture wall sections, one or more raised formations may be provided in abutment with the aperture wall sections. For another example, a plurality of protruding structures may be arranged side by side at intervals in the insertion direction of the sealing member 38, and at least one of the protruding structures may be capable of elastically abutting against the second hole-wall segment 3192. For another example, two side-by-side protruding structures are disposed on the insertion portion 381, one of the protruding structures elastically abuts against the second hole-wall segment 3192, and the other protruding structure elastically abuts against the first hole-wall segment 3191, so as to increase the waterproof and dustproof performance of the sealing member 38 on the housing 31. It should be noted that the convex structure is not limited to the annular protrusion 3811 described above, and the shape of the convex structure may be adapted according to the shape of the hole wall section.

It should be noted that: after the insertion portion 381 is removed from the jack 319, the interface 34 (shown in fig. 2) is exposed through the jack 319, so that the sound generating device 10 can perform data transmission, charging and other functions through the interface 34.

FIG. 5 is a cross-sectional structural view of the housing 31 of FIG. 3 according to some embodiments of the present application; fig. 6 and 7 are schematic structural views of a seal according to some embodiments of the present application. As shown in fig. 5, in some embodiments, the housing 31 further includes a mounting hole 320. When the interface 34 (shown in fig. 2) is in a use state of data transmission, charging, etc., that is, after the insertion portion 381 is taken out of the insertion hole 319, the sealing member 38 may be fixed on the housing 31 through the mounting hole 320, so as to prevent the sealing member 38 from being completely separated from the housing 31 and falling out.

In some embodiments, in conjunction with fig. 5-7, the seal 38 may include a mounting portion 382 that mates with the mounting aperture 320, wherein the mounting portion 382 connects with the insertion portion 381. In some embodiments, the insertion portion 381 may be integrally formed or otherwise connected with the mounting portion 382. The fitting portion 382 may be fixedly connected to the mounting hole 320, that is, the fitting portion 382 may be inserted into the mounting hole 320 and fixed to the housing 31. In some embodiments, the fastening connection of the mounting portion 382 to the mounting hole 320 may include one or more of snapping, bonding, welding, bolting, screwing, etc.

As shown in fig. 6 and 7, the sealing member 38 includes a connecting portion 383 connecting the insertion portion 381 and the mounting portion 382, and the insertion portion 381 and the mounting portion 382 are provided on the same side surface of the connecting portion 383. In some embodiments, the connection part 383 may be provided with the thinned structure 3831 such that an average thickness of the connection part 383 at the thinned structure 3831 is smaller than an average thickness of other portions of the connection part 383. In some embodiments, a thinned structure 3831 can be located between the insertion portion 381 and the mounting portion 382, such that the insertion portion 381 can be bent relative to the mounting portion 382 through the thinned structure 3831 to facilitate a user in removing the insertion portion 381 from the patch hole 319. As an example, the thinned structure 3831 may be a surface on the same side of the connection portion 383 as the insertion portion 381 and the mounting portion 382, so that the thinned structure 3831 is not visible after the sealing member 38 is plugged into the plug jack 319, so as to increase the consistency of the appearance structure of the sealing member 38. In some embodiments, the thinning structure 3831 and the insertion portion 381 and the fitting portion 382 may also be located at surfaces on different sides of the connection portion 383. In some embodiments, the average thickness of the connection portion 383 at the thinned structure 3831 may be approximately the same as the average thickness of other portions of the connection portion 383, and at this time, the bending of the insertion portion 381 relative to the mounting portion 382 may be realized by changing the material of the connection portion 383 at the thinned structure 3831. For example, the material of the connection portion 383 at the thinned structure 3831 may be elastic, and the other portions of the connection portion 383 may be hard, so that the insertion portion 381 can be bent with respect to the mounting portion 382 through the thinned structure 3831. In some embodiments, a cavity may also be opened at the connection portion 383 between the insertion portion 381 and the mounting portion 382 to achieve the function of the thinning structure 3831. In some embodiments, the number of thinned structures 3831 can be one or more. For example, the plurality of thinning structures 3831 may be arranged in an array, unevenly arranged, or the like.

As shown in fig. 6 and 7, the fitting portion 382 may include a connecting section 3821, a stopping section 3822, and a guiding section 3823, which are connected in sequence (e.g., integrally connected). The connecting section 3821 is connected to the connecting section 383, and the stopping section 3822 protrudes from the connecting section 3821 and the guiding 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, the diameter of the connecting section 3821 may be slightly smaller than the diameter of the mounting hole 320, so that the assembling portion 382 is mainly plugged into the mounting hole 320 in a one-way manner, and after the assembling portion 382 is plugged into the mounting hole 320, the stopping sections 3822 and the connecting portions 383 are respectively located on two opposite sides of the housing 31, so as to prevent the assembling portion 382 from falling out of the mounting hole 320, so that the assembling portion 382 is fixed to the housing 31 in a snap-fit manner. In some embodiments, the portion of the fitting portion 382 contacting the housing 31 may be coated with glue, which may increase the connection reliability of the two and may also increase the waterproof and dustproof performance of the housing 31 at the mounting hole 320. That is, the fitting portion 382 may always maintain a relatively fixed assembled relationship with the housing 31 and extend from the accommodating cavity 318 to the outside of the housing 31. In some embodiments, the mounting portion 382 may be a light-transmitting member, for example, made of polycarbonate or polyamide, and is disposed corresponding to the indicator light 35 (shown in fig. 2) to guide the light emitted from the indicator light 35 to the outside of the casing 31, so that the indicator light can indicate the situation that the sounding device 10 is charged or the power is insufficient. At this time, the indicator lamp 35 is disposed in the accommodation chamber 318, and is not visible from the outside of the housing 31. Compared with the structure that the indicator light 35 is exposed out of the shell 31 as shown in fig. 2, the shell 31 may have one less through hole structure corresponding to the indicator light 35, which is beneficial to increase the waterproof and dustproof performance of the shell 31.

In some embodiments, the mounting portion 382 and the insertion portion 381 may be made of the same or different materials. When the material of the assembling portion 382 is different from that of the inserting portion 381, the light transmittance of the assembling portion 382 to light may be greater than that of the inserting portion 381 to light, so that the light emitted from the indicator 35 is guided out of the housing 31 by the assembling portion 382 as much as possible, and the light guided by the assembling portion 382 is prevented from "leaking" to the inserting portion 381. When the assembling portion 382 and the inserting portion 381 are made of the same material, a light blocking member (shown in the figure) may be further disposed between the assembling portion 382 and the inserting portion 381, and a light transmittance of the light blocking member to light is smaller than that of the assembling portion 382 to light, so that light emitted from the indicator light 35 is guided to the outside of the housing 31 by the assembling portion 382 as much as possible, and the light guided by the assembling portion 382 is prevented from being guided to the outside of the housing 31 by the inserting portion 381. In some embodiments, a light block may be disposed at the thinned structure 3831. Further, the connection portion 383 between the fitting portion 382 and the insertion portion 381 may be replaced with the above-described light blocking member.

It should be noted that: the guide section 3823 may function primarily during assembly of the seal 38 with the housing 31, such as by first passing the guide section 3823 through the mounting hole 320 and then applying a force to the guide section 3823 to pull the stopper section 3822 through the mounting hole 320. Therefore, the guiding portion 3823 can be cut off after the sealing member 38 is assembled with the housing 31, so as to save the volume of the accommodating chamber 318 and facilitate the arrangement of other devices. Based on this, the indicator light 35 may also face and contact the end of the stopping section 3822 away from the connecting section 3821, so as to shorten the distance that the light emitted by the indicator light 35 travels to the outside of the housing 31, and reduce the loss of the light.

With reference to fig. 5 to 7, in some embodiments, a groove 321 may be further disposed on the housing 31 (specifically, the accommodating chamber 313), and the patch jack 319 and the mounting hole 320 are in communication with a bottom of the groove 321. Specifically, in the insertion direction of the seal 38, the groove 321 is located on a side of a first one of the at least one bore wall section facing away from the terminal bore wall section, e.g., a side of the first bore wall section 3191 facing away from the second bore wall section 3192. So configured, during insertion of the insertion portion 381 into the plug hole 319, the connection portion 383 is stopped by the bottom of the recess 321, thereby preventing "over-plugging" of the sealing member 38. In some embodiments, the connection 383 can be received in the recess 321 after the insertion portion 381 is inserted into the jack 319. At this time, the connection part 383 may be flush with the accommodating chamber 313.

After the sealing member 38 shown in fig. 6 and 7 is assembled with the housing 31, during the process of removing the insertion portion 381 from the plug hole 319 by the user, the insertion portion 381 can move relative to the mounting portion 382 through the thinning structure 3831, that is, the corner of the free end (the side away from the connecting portion 383) of the insertion portion 381 away from the mounting portion 382 has an arc relative to the movement track of the mounting portion 382. In doing so, the free end of the insertion portion 381 away from the corner of the mounting portion 382 may interfere structurally with the housing 31, especially in scenarios where the length of the insertion portion 381 (i.e., the depth of insertion of the insertion portion 381 into the plug aperture 319) is large. Accordingly, during insertion of the insertion portion 381 into the jack 319 by a user, the free end of the insertion portion 381 away from the corner of the mounting portion 382 may also interfere structurally with the housing 31. The insertion portion 381 is able to insert or remove the plug from the jack 319, which results in a time and labor consuming operation of the user due to the interference between the free end of the insertion portion 381 away from the corner of the mounting portion 382 and the housing 31. In this regard, the free end of the insertion portion 381 may be provided with an avoidance structure for reducing interference between the corner of the free end of the insertion portion 381 remote from the mounting portion 382 and the housing 31 during insertion of the insertion portion 381 into the jack 319 or removal of the insertion portion 381 from the jack 319. In some embodiments, the relief structure can be positioned at a corner remote from the mounting portion 382. Fig. 8 and 9 are schematic views of the seal 38 according to some embodiments of the present application. As shown in fig. 8, in some embodiments, the avoidance structure 3812 can be a chamfer. The chamfer may be provided at a corner of the free end of the insertion portion 381 distal from the mounting portion 382. As shown in fig. 9, in some embodiments, the avoidance structure 3812 can be at least one slot. Each of the at least one cutting groove may divide the free end of the insertion part 381 into at least two portions in a circumferential direction.

It should be noted that: as shown in fig. 8 and 9, the avoiding structure 3812 does not damage the annular protrusion 3811 as much as possible, so as to ensure the structural integrity of the annular protrusion 3811, and further ensure the waterproof and dustproof performance of the sealing member 38 on the housing 31.

In some embodiments, an avoidance structure 3812 may also be disposed at a corner of the free end of the insertion portion 381 near the mounting portion 382, so as to facilitate a user to plug the insertion portion 381 into the plug hole 319 or remove the insertion portion 381 from the plug hole 319 as much as possible while ensuring the waterproof and dustproof performance of the sealing member 38 on the housing 31.

In some embodiments, as shown in fig. 8 and 9, an end of the connecting portion 383 facing away from the fitting portion 382 may be further provided with a start position 3832. The average thickness of the connection portion 383 at the starting position 3832 can be less than the average thickness of the other portions to facilitate removal of the insertion portion 381 from the patch aperture 319 by a user. As an example, the origin 3832 may be located on the same side of the connection portion 383 as the insertion portion 381 and the mounting portion 382, so that the origin 3832 is not visible after the sealing member 38 is plugged into the plug hole 319, thereby increasing the consistency of the appearance structure of the sealing member 38.

Sound generating mechanism 10 need carry out the data burning when converting audio signal into sound signal (for example, bone conduction sound, gas conduction sound), for example, burn the application, sound generating mechanism 10 only is provided with the interface of burning record data usually, and sound generating mechanism 10 uses button cell to supply power usually, need frequently change the battery, and it is inconvenient to operate, need set up the corresponding interface that charges when replacing button cell for rechargeable battery, the interface that has the interface that charges and burn record data in the sound generating mechanism 10 simultaneously can improve sound generating mechanism 10's manufacturing cost, also be convenient for user's operation and use. Based on the above problem, an embodiment of the present specification provides a charging assembly, which includes an interface having a charging pin and a burning pin, and simultaneously implements 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 function of charging through the pin that charges to realize burning the function through burning the pin, realize two kinds of functions by an interface, need not to set up the interface that charges in addition, can reduce sound generating mechanism 10's manufacturing cost by a wide margin, also be convenient for user's operation simultaneously and use. Fig. 10 is a schematic diagram of a charging assembly 60 according to some embodiments of the present application. The charging assembly 60 may include an interface 610, a processing chip 620, a battery management module 630, and a battery 640, the charging assembly 60 may be located inside the accommodating cavity 318 of the housing 31 (shown in fig. 2), and reference may be made to the description of the interface 34 in fig. 2 regarding the position of the interface 610 in the housing 31.

In some embodiments, interface 610 may include at least one charge pin and at least one burn pin. The charging pin is used to supply power to the sound generating device 10. The burning pins are used for burning data to adjust parameters of the sound generating device 10, so that the sound generating device 10 can be adapted to different users. In some embodiments, the interface 610 can use only one of the charging pin or the burn pin during the same time period to realize the charging function or the burn function. In some embodiments, the interface 610 may use the charging pin and the burning pin simultaneously during the same time period to realize the charging function and the burning function.

The processing chip 620 may be connected to the at least one burn pin. The processing chip 620 burns data through the at least one burning pin. For example, the processing chip 620 burns programs with specific parameters through the at least one burning pin. In some embodiments, the characteristic parameters may include parameters such as response frequency, sensitivity, signal-to-noise ratio, transient response, and distortion level.

The battery management module 630 may be configured to control the charging current of the battery 640. The battery 640 may be configured to power the sound generator 10. Specifically, the battery management module 630 may be connected to the interface 610 through the at least one charging pin, and configured to receive an input voltage (e.g., 5V), process the input voltage, control a charging current of the battery 640, and further implement charging of the battery 640. Illustratively, the battery management module 630 may include a BQ24045 module or other model of battery management module. The input voltage received by the battery management module 630 may be 5V.

The battery 640 may be connected to the battery management module 630 and the processing chip 620, respectively. When the battery 640 completes charging through the battery management module 630, the battery 640 stops charging. Meanwhile, the battery 640 outputs a voltage to the processing chip 620 to provide an operating voltage to the processing chip 620. Illustratively, the output voltage of the battery 640 may be 1.2V.

In some embodiments, battery 640 may comprise a fast-charging lithium battery. The maximum current of the fast-charging lithium battery can reach 3C (C is the total capacity of the battery), and compared with the common rechargeable lithium battery, the maximum current can be increased by 6-15 times, so that the fast charging of the battery 640 is realized.

In some embodiments, the battery management module 630 may control the charging current of the battery 640 according to the voltage of the battery 640. In some embodiments, the battery management module 630 controlling the charging current of the battery 640 according to the voltage of the battery 640 may include: the battery management module 630 obtains the voltage of the battery 640, and the battery management module 630 determines 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 preset voltage range (e.g., 0V-4.35V), the charging current is controlled to be a first preset current, so that the battery 640 is rapidly charged, and at this time, the battery 640 is in a stage of constant current charging, and the charging current is a first preset current (e.g., 540 mA). In order to prevent the voltage corresponding to the battery 640 from being excessively high during the constant current charging of the battery 640, further, in some embodiments, the controlling, by the battery management module 630, the charging current of the battery 640 according to the voltage of the battery 640 may further include: the battery management module 630 determines whether the voltage of the battery 640 is within a second preset voltage range (e.g., greater than or equal to 4.35V), and 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 to decrease the charging current, at which time the battery 640 is in a constant voltage charging stage, and the charging voltage is a specific value (e.g., 4.35V) of the second preset voltage range. If the battery management module 630 detects that the voltage of the battery 640 is smaller than the preset second preset voltage range, the battery management module 630 may control the charging current to be the first preset current, so that the battery 640 continues to be in the stage of constant current charging. During the constant voltage charging process of the battery 640, the charging current of the battery 640 gradually decreases, that is, the charge amount of the battery 640 when the charging current decreases to a certain value can be considered to be full, further, in some embodiments, the controlling of the charging current of the battery 640 by the battery management module 630 according to the voltage of the battery 640 may further include: it is determined whether the battery management module 630 detects that the charging current reaches a second predetermined current range (e.g., less than or equal to 27mA), if the charging current reaches or is less than the second predetermined current range, the battery management module 630 may control the battery 640 to stop charging, and if the charging current is greater than the second predetermined current range, the battery management module 630 may 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 may be set according to the performance of the battery 640. For example, the first preset voltage range may be 0V to 4.35V, the second voltage may be 4.35V, the first current may be 540mA, and the second current may be 27mA, i.e., the operating voltage of the battery 640 may be 4.35V, and the off-current may be 27 mA.

In some embodiments, the charging assembly 60 may further include a voltage regulator, a power amplifier chip, and the like, wherein the voltage regulator and the power amplifier chip may be implemented as components in the charging assembly 60 or components in the motherboard 50 shown in fig. 2. The voltage regulator may be used to convert the output voltage of the battery 640 into a regulated voltage. The input of the voltage regulator may be connected to the output of the battery 640, and the output of the voltage regulator may be connected to the input of the processing chip 620. The input end of the power amplifier chip may be connected to the output end of the processing chip 620, and is configured to amplify the audio signal of the processing chip 620. The output end of the power amplifier chip may be connected to a speaker (also referred to as a loudspeaker) in the core 20 (shown in fig. 1), and the speaker is configured to output the audio signal of the processing chip 620 amplified by the power amplifier chip. In some embodiments, the sound generating device 10 may further include at least one microphone, which may be connected to an input of the processing chip 620 and output the received audio signal to the processing chip 620.

By way of example only, fig. 11 is an exemplary block diagram of a sound emitting device 70 according to some embodiments of the present application. The sound generating device 70 is based on the charging assembly 60 shown in fig. 10, and further includes a voltage stabilizer 710, a power 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 assembly includes a first processing chip 620-1 and a second processing chip 620-2.

The input end of the voltage stabilizer 710 is connected to the output end of the battery 640, and the output end of the voltage stabilizer 710 is connected to the input ends of the first processing chip 620-1 and the second processing chip 620-2, respectively, for converting the output voltage of the battery 640 into a regulated voltage and outputting the regulated voltage to the first processing chip 620-1 and the second processing chip 620-2, so as to provide a working voltage for the first processing chip 620-1 and the second processing chip 620-2. An input terminal of the first processing chip 620-1 is connected to an output terminal of the first microphone 740-1. An input terminal of the second processing chip 620-2 is connected to an output terminal of the second microphone 740-2. The output ends of the first processing chip 620-1 and the second processing chip 620-2 are respectively connected with the input end of the power amplifier chip 720. The output end of the power amplifier chip 720 is connected to the input ends of the first speaker 730-1 and the second speaker 730-2, respectively.

In some embodiments, the operating voltage of the battery 640 is different from the operating voltage of the processing chips 620 (e.g., the first processing chip 620-1 and the second processing chip 620-2), and the output voltage of the battery 640 may be converted into a regulated voltage by the voltage regulator 710. The regulated voltage may 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 voltages of the first processing chip 620-1 and the second processing chip 620-2 are 1.2V, and the output voltage of the battery 640 cannot be directly used as the operating voltages of the first processing chip 620-1 and the second processing chip 620-2, and needs to be stepped down. Therefore, the voltage regulator 710 is provided at the output terminal of the battery 640, and the output voltage of the battery 640 can be stepped down.

In some embodiments, the voltage regulator 710 may include a low dropout linear regulator capable of converting an acceptable input voltage (e.g., 4.35V) to an appropriate output voltage (e.g., 1.2V) such that the output voltage can satisfy the operating voltage requirements of the first processing chip 620-1 and the second processing chip 620-2. Illustratively, voltage regulator 710 may comprise a NCP163AMX120TBG type voltage regulator, or other type of voltage regulator.

The first microphone 740-1 outputs the received audio signal to the first processing chip 620-1. The first processing chip 620-1 performs processing of a correlation algorithm on the audio signal, and outputs the processed audio signal to the power amplifier chip 720. The power amplifier chip 720 amplifies the audio signal. The first speaker 730-1 outputs the audio signal amplified by the power amplifier chip 720. Illustratively, the power amplifier chip 720 may include a MAX98306 chip or other types of power amplifier chips.

The second microphone 740-2 outputs the received audio signal to the second processing chip 620-2. The second processing chip 620-2 performs processing of a correlation algorithm on the audio signal, 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 may be respectively disposed at the two cartridges 20 shown in fig. 1 or at 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. Bone conduction microphone is used for acquireing the vibration signal of user's facial muscle when speaking to convert this vibration signal into audio signal and export and handle to processing chip, and meanwhile, the influence of sound among the external environment to bone conduction microphone is less, that is to say that bone conduction microphone does not pick up the sound among the external environment hardly, can satisfy the use under the specific scene (for example, the user talks in comparatively noisy environment) through set up bone conduction microphone in sound generating mechanism, improve user's speech quality. An air conduction microphone may be used to pick up sound that is propagated through the air (e.g., sounds in the external environment, sounds of a user speaking, etc.).

In some embodiments, 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 Lighting interface, and the like. To facilitate a detailed description of interface 610, with TYPE-C interface as an exemplary illustration, fig. 12 is a wiring definition diagram of interface 610 according to some embodiments of the present application. Interface 610 is a TYPE-C interface and can be compatible with a pin corresponding to the USB3.0 protocol. As shown in FIG. 12, the USB3.0 protocol may include a TX1+ pin, a TX 1-pin, an RX1+ pin, an RX 1-pin, a TX2+ pin, a TX 2-pin, an RX2+ pin, an RX 2-pin, a VBUS pin, and the like. The TX1+ pin is connected to the TX2+ pin, forming a TX + pin. The TX 1-pin is connected with the TX 2-pin to form a TX-pin. RX1+ pin is connected to RX2+ pin, forming RX + pin. RX 1-pin is connected to RX 2-pin, forming RX-pin.

By way of example only, fig. 13 is a schematic block diagram of an interface 610 according to some embodiments of the present application. The TX + pin, TX-pin, RX + pin, and RX-pin illustrated in fig. 12 correspond to the SSTXP1 pin, SSTXN1 pin, SSRXP1 pin, and SSRXN1 pin illustrated in fig. 13, respectively. The VBUS pin corresponds to the VBUS0 pin shown in FIG. 13. The interface 610 uses a TX + pin, a TX-pin, an RX + pin, and an RX-pin as a burning pin of the TYPE-C interface, and uses a VBUS0 pin as a charging pin of the TYPE-C interface.

The interface 610 is connected to the first processing chip 620-1 and the second processing chip 620-2, respectively, and the burning pins of the 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 the first processing chip 620-1 and the second processing chip 620-2 burn data at the same time. Specifically, the I2C interface of the first processing chip 620-1 includes SCL1 pins and SAD1 pins, and the I2C interface of the second processing chip 620-2 includes SCL2 pins and SAD2 pins. The TX + pin and the TX-pin are respectively connected with the SCL1 pin and the SAD1 pin, and the RX + pin and the RX-pin are respectively connected with the SCL2 pin and the SAD2 pin.

In some embodiments, the processing chip 620 (e.g., the E7111 chip) has a high requirement for static electricity sensitivity, and needs to be antistatic-treated, and for this purpose, the sound emitting device 10 may further include one or more components (e.g., TVS tubes (Transient Voltage supplies)) for antistatic treatment. For example, as shown in fig. 13, the sound emitting 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. As shown in fig. 13, one end of the first TVS transistor D1 is connected to the SCL1 pin, one end of the second TVS transistor D2 is connected to the SAD1 pin, one end of the third TVS transistor D3 is connected to the SCL2 pin, one end of the fourth TVS transistor D4 is connected to the SAD2 pin, one end of the fifth TVS transistor D5 is connected to the VBUS0 pin, and the other ends of the first TVS transistor D1, the second TVS transistor D2, the third TVS transistor D3, the fourth TVS transistor D4, and the fifth TVS transistor D5 are grounded. When large-amplitude transient interference voltage or pulse current appears due to thunder and various electrical appliance interference in the circuit, the TVS tube can be quickly switched into a reverse conduction state within extremely short time, and the voltage of the circuit is clamped on a required safety value, so that precision components in an electronic circuit are effectively protected from being damaged. After the interference pulse passes, the TVS tube is switched to a reverse cut-off state again. When the TVS tube is conducted in the reverse direction, the clamping voltage of the TVS tube is lower than the highest withstand voltage of the E7111 chip, so that the TVS tube plays a role in protecting the E7111 chip.

In some embodiments, as shown in fig. 13, the interface 610 may further include an identification pin CC1 for identifying the functional accessory to allow the sound emitting device 10 to be matingly connected to the functional accessory. Optionally, the functional accessory may be an external burning device or the like.

In some embodiments, as shown in fig. 13, the sound emitting device 10 may further include a pull-down resistor R1, one end of the pull-down resistor R1 is connected to the identification pin CC1, and the other end of the pull-down resistor R1 is grounded. Illustratively, the pull-down resistor R1 has a resistance of 5.1k Ω. In this embodiment, the pull-down resistor R1 is provided at one end of the identification pin CC1, so that the noise margin of the input signal of the sound generating device 10 can be improved, and the resistance matching can be performed to enhance the anti-interference capability.

According to some embodiments of the present application, by providing the interface 610 including at least one charging pin and at least one burning pin, the charging and burning functions of the sound generating device 10 can be simultaneously realized, so that the charging operation of the sound generating device 10 is convenient and simple. The interface 610 realizes the charging function through the charging pin, realizes the burning function through the burning pin, realizes two functions through one interface, need not to set up the interface that charges in addition, can reduce cost.
