Technical field

[0002] The present application relates to the field of eyeglasses, in particular eyeglasses with loudspeakers. State of the art

[0003] With the development of loudspeaker technology, electronic products such as earphones, MP3 players, and so on have found widespread application. Loudspeakers can take various forms. For example, they can be integrated into eyewear (sunglasses, swimming goggles, etc.). Alternatively, they can be attached to or near a user's ear using special structures (e.g., ear hooks). As the functionality of these products increases, the number of internal modules and wiring within a loudspeaker steadily grows. The wiring itself also becomes increasingly complex. Such complex wiring occupies a significant portion of the product's interior space. Furthermore, an unfavorable distribution of wires can lead to mutual interference, generating abnormal noise that, in turn, affects the loudspeaker's sound reproduction quality.Therefore, it is necessary to provide a more efficient wiring technology that simplifies the wiring in the loudspeaker and improves the sound quality of the loudspeaker.

Detailed descriptions

[0006] To clarify the technical solutions of the embodiments of the present application, the figures necessary for describing these embodiments are briefly presented. Obviously, the figures described below represent only a few examples or embodiments of the present application. With the help of these figures, a person skilled in the art in this field can apply the present application to other similar scenarios without inventive step. It should be understood that these exemplary embodiments are provided solely to enable those skilled in the relevant field to better understand and thus implement the present invention, and are in no way intended to limit the scope of the present invention. Unless obvious from the context or otherwise indicated, identical reference numerals in the drawings refer to identical structures or processes.

[0007] As shown in the present application and in the claims, the terms "a" and / or "the" need not necessarily refer to the singular form, but may also include the plural form, unless the context clearly indicates otherwise. Generally speaking, the terms "comprise" and "contain" merely serve to indicate the inclusion of expressly identified steps and elements, and these steps and elements do not constitute an exclusive list. Methods or devices may also contain other steps or elements. The term "based on" refers to "at least partially based on." The term "an embodiment" refers to "at least one embodiment."

[0008] Fig. Figure 1 shows a modular structural representation of a loudspeaker according to some embodiments of the present application.

[0009] The loudspeaker 100 can comprise at least one earphone core 102, one auxiliary function module 104 and one soft circuit board 106.

[0010] In some embodiments, the earphone core 102 can receive electrical audio signals and convert them into sound signals. The flexible circuit board 106 provides electrical connections between different modules / arrangements. For example, the flexible circuit board 106 can provide electrical connections between the earphone core 102 and an external control circuit, as well as the auxiliary function module 104.

[0011] In some embodiments, the earphone core 102 may comprise at least one magnetic circuit assembly, a vibration assembly, and a support for the magnetic circuit assembly and the vibration assembly. The magnetic circuit assembly serves to provide a magnetic field. The vibration assembly serves to convert electrical signals input to the vibration assembly into mechanical vibration signals, thereby generating sound. In some embodiments, the vibration assembly may comprise at least one coil and an internal guide wire. In some embodiments, the earphone core 102 further comprises an external wire that can transmit audio current to the coil for the vibration assembly. One end of the external wire may be connected to the internal guide wire of the earphone core, and the other end is connected to the flexible circuit board of the loudspeaker.In some embodiments, the support may have a cable tray, wherein the external cable and / or the internal cable may be partially arranged in the cable tray. For details, please refer to the description in other sections of this application.

[0012] In some embodiments, the auxiliary function module 104 can serve to receive auxiliary signals and perform an auxiliary function. The auxiliary function module 104 can be a module located outside the earphone core and used to receive auxiliary signals in order to perform an auxiliary function. In the present application, the conversion of the audio signals into sound signals can be considered the main function of the loudspeaker 100, while functions other than the main function can be considered auxiliary functions of the loudspeaker 100. For example, the auxiliary functions of the loudspeaker 100 can include receiving sound from the user and / or the environment through a microphone, controlling a playback process of the sound signals by means of a button, etc. A corresponding auxiliary function module can be a microphone, a push-button switch, or the like, depending on the actual requirements.The auxiliary signal can be an electrical signal, an optical signal, a sound signal or a vibration signal, or a combination of several of them, that are relevant to an auxiliary function.

[0013] The loudspeaker 100 further comprises a core housing 108 for receiving the earphone core 102, the auxiliary function module 104, and the soft circuit board 106. If the loudspeaker 100 is a bone conduction earphone, an inner wall of the core housing 108 can be directly or indirectly connected to the vibrating assembly of the earphone core. When the user wears the bone conduction earphone, an outer wall of the core housing 108 is in contact with the user and transmits the mechanical vibration of the vibrating assembly via the bone to the auditory nerve, so that sound is heard. In some embodiments, the loudspeaker may comprise an earphone core 102, an auxiliary function module 104, a soft circuit board 106, and a core housing 108.

[0014] In some embodiments, the soft printed circuit board 106 can be a flexible printed circuit board (FPC) and can be accommodated within the core housing 108. The soft printed circuit board 106 can exhibit high flexibility and thus adapt to the interior of the core housing 108. In some embodiments, the soft printed circuit board 106 can, in particular, comprise a first board body and a second board body. The soft printed circuit board 106 can be bent at the first and second board bodies to adapt to its position within the core housing 108. More specific details are provided in the description in other sections of this application.

[0015] In some embodiments, the loudspeaker 100 transmits sound via bone conduction. An outer surface of the core housing 108 may have a contact surface. This contact surface is an outer surface of the loudspeaker 100 that is in contact with the human body when the user wears the loudspeaker 100. The loudspeaker 100 can press the contact surface against a predetermined area (the anterior end of the tragus, the position of the skull bones, or the back of the auricle) to effectively transmit the vibration signals via the bones to the user's auditory nerve, thus enhancing the sound quality of the loudspeaker 100. In some embodiments, the contact surface may rest against the back of the auricle. The mechanical vibration signals are transmitted from the earphone core to the core housing and, via the contact surface of the core housing, to the back of the auricle.Again, the vibration signals are transmitted from the bones near the back of the ear to the auditory nerve. In this case, the bones near the back of the ear are closer to the auditory nerve and exhibit better conductivity, thus increasing the efficiency of sound transmission from the speaker to the auditory nerve.

[0016] In some embodiments, the loudspeaker 100 may further include a mounting mechanism 110. The mounting mechanism 110 is externally connected to the core housing 108 to support the core housing 108 and maintain its position. In some embodiments, a battery assembly and a control circuit may be arranged within the mounting mechanism 110. The battery assembly may power any electronic arrangement for the loudspeaker 100. The control circuit may control any functional arrangement for the loudspeaker 100. The functional arrangement may include, but is not limited to, an earphone core, an auxiliary function module, or the like. The control circuit may be connected to a battery and another functional arrangement either via a flexible circuit board or via a wire.

[0017] In some embodiments, the fastening mechanism 110 can be a spectacle frame, a cap, a headdress, or other head covering, or a combination of several of these. For example, the fastening mechanism 110 can be a spectacle frame. Inside the spectacle frame, a cavity can be formed to accommodate the battery assembly, the flexible circuit board, and the control circuitry. In this case, the earphone core 102 can be located at the rear end of a spectacle temple. It rests against the ear and delivers sound signals when the user is wearing spectacles.

[0018] Fig. Figure 2 shows a schematic structural representation of a soft printed circuit board inside a core housing according to some embodiments of the present application.

[0019] In some embodiments, multiple solder pads can be provided on the soft circuit board. Several different soft guide wires are used to electrically connect various signal lines (such as an audio signal line or an auxiliary signal line) to different solder pads. This avoids the need to connect the audio signal line and the auxiliary signal line to the earphone core or the auxiliary function module, thus preventing the problem of numerous and complex internal wires. As shown in Fig. 2 and Fig. As shown in Figure 3, a soft printed circuit board 44 comprises at least several first solder pads 45 and several second solder pads (not shown in the figures). In some embodiments, the soft printed circuit board 44 corresponds to the following: Fig. 2 of the soft circuit board 106 in Fig. 1. At least one first solder pad 45 of the first solder pads 45 is electrically connected to the auxiliary function module. This at least one first solder pad 45 is electrically connected to at least one of the second solder pads via a first flexible guide wire 47 on the flexible circuit board 44. This at least one second solder pad is electrically connected to the earphone core (not shown in the figures) via an external wire (not shown in the figures). At least one other first solder pad 45 of the first solder pads 45 is electrically connected to the auxiliary signal wire. This at least one other first solder pad 45 is electrically connected to the auxiliary function module via a second flexible guide wire 49 on the flexible circuit board 44. In the present embodiment, at least one first solder pad 45 is electrically connected to the auxiliary function module. At least one second solder pad is electrically connected to the earphone core via the external wire.The first flexible guide wire 47 electrically connects one of the at least one first solder pad 45 to one of the at least one second solder pad. This simultaneously connects the external audio signal line and the auxiliary signal line to the earphone core and several auxiliary function modules via the flexible circuit board, thus simplifying the wiring layout.

[0020] In some embodiments, the audio signal line may be a line electrically connected to the earphone core and transmitting audio signals to the earphone core. The auxiliary signal line may be a line electrically connected to the auxiliary function module and transmitting signals to the auxiliary function module.

[0021] With reference to Fig. In particular, in some embodiments, the soft circuit board 44 is provided with several solder pads 45 and two solder pads (not shown in the figures), wherein the two solder pads and the several solder pads 45 are located on the same side of the soft circuit board 44 and are spaced apart from each other. Furthermore, the two solder pads are connected to two corresponding solder pads 45 of the several solder pads 45 on the soft circuit board 44 via the soft guide wire 47. It is also provided that the core housing 41 accommodates two external wires, with one end of each external wire being welded to a respective solder pad and the other end being connected to the earphone core, so that the earphone core is connected to the solder pad via the external wire.The auxiliary function module can be mounted on the soft circuit board 44 and connected to another of the several solder pads 45 on the soft circuit board 44 via a soft guide wire 49.

[0022] In some embodiments, conductors are provided in the mounting mechanism 110 of the loudspeaker 100, wherein the conductors comprise at least one audio signal conductor and one auxiliary signal conductor. In some embodiments, several conductors may be provided in the mounting mechanism 110, wherein the conductors comprise at least two audio signal conductors and at least two auxiliary signal conductors. For example, the mounting mechanism 110 may be a spectacle frame. The spectacle frame is connected to the core housing 41. The conductors may be arranged within the spectacle frame. One end of the conductor in the spectacle frame is welded to a control circuit board, while the other end enters the interior of the core housing 41 and is welded to the solder pad 45 on the soft circuit board 44.

[0023] In this arrangement, one end of two audio signal lines located in the core housing 41 is welded to two solder pads 45, to which two soft guide lines 47 are welded, while the other end can be connected directly or indirectly to the control circuit board. The two solder pads 45 are further connected to the earphone core by the welding of a soft guide line 49 to two solder pads 46 and by the welding of two external lines to the solder pads, in order to transmit audio signals to the earphone core.

[0024] The ends of at least two auxiliary signal lines located in the core housing 41 are welded to solder pads 45, to which the soft guide line 49 is welded, while other ends of these lines can be connected directly or indirectly to the control circuit board. This allows auxiliary signals received by the auxiliary function module and obtained through conversion to be transmitted to a control circuit (not shown in the figures).

[0025] In the manner described above, the flexible circuit board 44 is arranged in the core housing 41, and a solder pad is arranged on the flexible circuit board 44. This allows a conductor (not shown in the figures) to be soldered to a corresponding solder pad after entering the core housing 41. From there, it is connected to the appropriate auxiliary function module via the flexible guide wire 47 and the flexible guide wire 49 on the solder pad. This avoids the need for multiple conductors to be directly connected to the auxiliary function module, thus preventing complex wiring within the core housing 41. This optimizes the wiring layout and saves space within the core housing 41.Furthermore, if several leads of the spectacle frame are directly connected to the auxiliary function module, middle sections of the spectacle frame leads are suspended within the core housing 41, which easily leads to vibration, resulting in abnormal noise and thus affecting the sound generation quality of the earphone core. However, by welding the spectacle frame leads to the soft circuit board 44 and further connecting them to the respective auxiliary function modules as described above, the influence of the suspended leads on the sound generation quality of the earphone core can be reduced, thus improving the sound generation quality of the earphone core to some extent.

[0026] In some embodiments, the soft circuit board (or referred to as soft circuit board 44) ​​can be further subdivided into sections. The soft circuit board is divided into at least two sections. An auxiliary function module can be arranged in each section, so that at least two auxiliary function modules can be arranged on the soft circuit board. The wiring between the audio signal line and the auxiliary signal line and at least two auxiliary function modules is achieved via the soft circuit board. In some embodiments, the soft circuit board can comprise at least one primary circuit board and a first secondary circuit board. The first secondary circuit board is connected to the primary circuit board and extends away from the primary circuit board along one end of the primary circuit board. The auxiliary function module can comprise at least one first auxiliary function module and one second auxiliary function module.The first auxiliary function module can be located on the primary circuit board. The second auxiliary function module can be located on the first secondary circuit board. Several first solder pads can be located on the primary circuit board. The second solder pad can be located on the first secondary circuit board. In some embodiments, the first auxiliary function module can be a push-button switch. The push-button switch can be located on the primary circuit board, and the first solder pad is located corresponding to the push-button switch. The second auxiliary function module can be a microphone. The microphone is located on the first secondary circuit board, and a second solder pad corresponding to the microphone is located on the first secondary circuit board.By connecting the first solder pad on the primary circuit board corresponding to the button switch to the second solder pad on the first secondary circuit board corresponding to the microphone via the second soft guide wire, the button switch can be electrically connected to the microphone, so that the button switch can control or acknowledge the microphone.

[0027] In some embodiments, the flexible printed circuit board (PCB) may further comprise a second secondary PCB. The second secondary PCB is connected to the primary PCB, extends from the primary PCB along the other end of the primary PCB, and is spaced apart from the first secondary PCB. The auxiliary function module may further comprise a third auxiliary function module. The third auxiliary function module is arranged on the second secondary PCB. The multiple first solder pads are arranged on the primary PCB, at least one of the second solder pads is arranged on the first secondary PCB, and the other second solder pads are arranged on the second secondary PCB. In some embodiments, the third auxiliary function module may be a second microphone.The second secondary circuit board extends perpendicular to the primary circuit board, the second microphone is mounted at an end of the second secondary circuit board farther from the primary circuit board, and several solder pads are arranged at an end of the primary circuit board farther from the second secondary circuit board.

[0028] As in Fig. 2 and Fig. As shown in Figure 3, the second auxiliary function module can be, in particular, a first microphone 432a and the third auxiliary function module a second microphone 432b. The first microphone 432a and the second microphone 432b can be MEMS (microelectromechanical system) microphones 432, which exhibit low operating current, relatively stable performance, and high speech quality. The two microphones 432 can be arranged in different positions on the flexible circuit board 44, depending on the actual requirements.

[0029] The flexible circuit board 44 comprises a primary circuit board 441 (or referred to as the primary circuit board), a secondary circuit board 442 (or referred to as the first secondary circuit board), and a secondary circuit board 443 (or referred to as the second secondary circuit board), which are connected to the primary circuit board 441. The secondary circuit board 442 and the primary circuit board 441 extend in the same direction. The first microphone 432a is mounted at an end of the secondary circuit board 442 furthest from the primary circuit board 441. The secondary circuit board 443 extends perpendicular to the primary circuit board 441. The second microphone 432b is mounted at an end of the secondary circuit board 443 furthest from the primary circuit board 441. Several solder pads 45 are arranged at an end of the primary circuit board 441 furthest from the secondary circuit board 442 and the secondary circuit board 443.

[0030] In one embodiment, the core housing 41 comprises a circumferential wall 411 and a bottom wall 412 connected to an end face of the circumferential wall 411, thus forming a receiving chamber with an open end. The earphone core is placed into the receiving chamber through the open end. The first microphone 432a is attached to the bottom wall 412, and the second microphone 432b is attached to the circumferential wall 411.

[0031] In the present embodiment, the secondary circuit board 442 and / or the secondary circuit board 443 can be appropriately bent to adapt to the positions of the sound inlet openings corresponding to the microphones 432 in the core housing 41. In particular, the flexible circuit board 44 can be arranged in the core housing 41 such that the primary circuit board 441 runs parallel to the bottom wall 412. This allows the first microphone 432a to be aligned with the bottom wall 412 without bending the primary circuit board 441. However, because the second microphone 432b is attached to the circumferential wall 411 of the core housing 41, the second primary circuit board 441 must be bent.In particular, the secondary circuit board 443 can be bent at the end furthest from the primary circuit board 441, so that the plate surface of the secondary circuit board 443 is perpendicular to the plate surfaces of the primary circuit board 441 and the secondary circuit board 442, and that, in turn, the second microphone 432b is attached to the circumferential wall 411 of the core housing 41 in a direction pointing away from the primary circuit board 441 and the secondary circuit board 442.

[0032] In one embodiment, the solder pad 45, the solder pad, the first microphone 432a and the second microphone 432b can be arranged on the same side of the soft circuit board 44 and the solder pad is arranged adjacent to the second microphone 432b.

[0033] The solder pad can be located, in particular, at the end of the secondary circuit board 443 furthest from the primary circuit board 441, and it is aligned in the same direction as the second microphone 432b and spaced apart from it, so that when the secondary circuit board 443 is bent, it is perpendicular to the orientation of the solder pad 45. It should be noted that the surface of the secondary circuit board 443 may not be perpendicular to the surface of the primary circuit board 441 after bending, depending on the arrangement of the circumferential wall 411 and the bottom wall 412.

[0034] Furthermore, it is provided that on another side of the soft circuit board 44 a rigid support plate 4a for supporting the solder pad 45 and a rigid support plate 4b for the microphone are provided. The rigid support plate 4b for the microphone comprises a rigid support plate 4b1 for supporting the first microphone 432a and a rigid support plate 4b2 for jointly supporting the solder pad 46 and the second microphone 432b.

[0035] The rigid support plates 4a, 4b1, and 4b2 primarily serve to support the respective solder pads and microphones 432, and therefore must possess a certain degree of rigidity. The materials used for the three plates can be either the same or different. These materials can be polyimide (polyimide film, PI) or other materials capable of providing sufficient support, such as polycarbonate, polyvinyl chloride, or similar materials. Furthermore, the thicknesses of the three rigid support plates can be adjusted according to their own inherent rigidity as well as according to the specific rigidity requirements of the solder pad 45, the solder pad, the first microphone 432a, and the second microphone 432b, although this is not explicitly defined here.

[0036] The rigid support plate 4a, the rigid support plate 4b1 and the rigid support plate 4b2 can either represent three different areas of a whole rigid support plate or three spaced-apart, individual wholes, although this is not specifically defined here.

[0037] In one embodiment, the first microphone 432a and the second microphone 432b correspond to two microphone assemblies (not shown in the figures). In this embodiment, the two microphone assemblies have the same structure. The core housing 41 is provided with a sound inlet opening 413. Furthermore, the loudspeaker assembly on the core housing 41 is provided with an annular barrier 414, which is integrally formed on the inner surface of the core housing 41. The annular barrier is formed peripherally at the sound inlet opening 413 and in turn defines a receiving chamber connected to the sound inlet opening 413 (not shown in the figures).

[0038] In one embodiment, the soft circuit board 44 can be arranged between the rigid support plates (such as the rigid support plate 4a, the rigid support plate 4b1 and the rigid support plate 4b2) and the microphones 432, and it is provided in a position corresponding to a sound inlet opening 4b3 of the rigid support plate 4b for the microphone, with a sound inlet opening 444.

[0039] Furthermore, the flexible circuit board 44 extends further in a direction away from the microphones 432 in order to connect with other functional elements or lines and thus fulfill their respective functions. Accordingly, the rigid support plate 4b for the microphone also extends with the flexible circuit board in a direction away from the microphones 432 over a distance.

[0040] Accordingly, the annular barrier wall 414 is provided with a notch that fits the shape of the soft circuit board 44, allowing the soft circuit board 44 to extend beyond the receiving space. Furthermore, a sealant can be applied to the notch to further increase the seal.

[0041] As in Fig. As shown in Figure 4, in some embodiments the soft printed circuit board 44 can comprise a primary printed circuit board 445 and a secondary printed circuit board 446, the secondary printed circuit board 446 extending in a direction perpendicular to the primary printed circuit board 445. Several solder pads 45 are arranged at an end of the primary printed circuit board 445 furthest from the secondary printed circuit board 446. The push-button switch is mounted on the primary printed circuit board 445. The solder pad 46 is arranged at an end of the secondary printed circuit board 446 furthest from the primary printed circuit board 445. The first auxiliary function module can be a push-button switch 431 and the second auxiliary function module a microphone 432.

[0042] In the present embodiment, the plate surface of the soft circuit board 44 is arranged parallel to and spaced apart from the bottom wall 412, so that the push button switch can be arranged facing the bottom wall 412 of the core housing 41.

[0043] As previously described, the earphone core (or earphone core 102) can comprise a magnetic circuit assembly, a vibrating assembly, external lead, and a support. The vibrating assembly can include a coil and an internal guide lead. The external lead can carry audio current to the coil for the vibrating assembly. One end of the external lead can be connected to the internal guide lead of the earphone core, and the other end is connected to the soft circuit board of the loudspeaker. The support can have a cable tray, with the external lead and / or the internal lead being at least partially located in the cable tray. In some embodiments, the internal guide lead and the external guide lead can be welded together, with the weld being located in the cable tray.

[0044] See Fig. 5 and Fig. 6. The earphone core comprises, in particular, a carrier 421, a coil 422, and an external cable 48. The carrier 421 serves to support and protect the entire structure of the earphone core. In the present embodiment, the carrier 421 is provided with a cable channel 4211, which can be used to receive the wires of the earphone core.

[0045] The coil 422 can be arranged on the support 421 and has at least one internal guide wire 423, wherein one end of the internal guide wire 423 is connected to a main wire of the coil 422 in order to lead the main wire out and to transmit audio current to the coil 422 via the internal guide wire 423.

[0046] One end of the external line 48 is connected to the internal guide line 423. Furthermore, it is provided that the other end of the external line 48 can be connected to a control circuit (not shown in the figures) in order to transmit audio current to the coil 422 via the internal guide line 423.

[0047] In particular, during the assembly phase, the external lead 48 and the internal guide lead 423 must be joined together by welding or similar means. Due to structural limitations, it is not possible for the lead length to perfectly match the length of a channel after welding is complete. Typically, there is excess lead length. If this excess length cannot be properly positioned, it will vibrate in sync with the coil 422, generating abnormal noise and thus affecting the quality of the sound produced by the earphone core.

[0048] Furthermore, it is provided that at least one of the external conductor 48 and the internal guide conductor 423 can be wound in the cable tray 4211. In one application scenario, the weld point of the internal guide conductor 423 with the external conductor 48 in the cable tray 4211 can be adjusted to allow a portion of the external conductor 48 and the internal guide conductor 423 located near the weld point to be wound in the cable tray 4211. Additionally, to maintain stability, it is provided that sealant can be poured into the cable tray 4211 to secure the wiring within the cable tray 4211.

[0049] In the above manner, the carrier 421 is provided with the cable trough 4211 in order to arrange at least one of the external line 48 and the internal guide line 423 wound in the cable trough 4211 and thus accommodate the wiring with excess length, so that its vibration in the channel is weakened and in turn the influence on the quality of the sound produced by the earphone core is reduced due to the abnormal noise caused by the vibration.

[0050] In one embodiment, the support 421 comprises an annular main body 4212, a support flange 4213, and an outer barrier wall 4214. The annular main body 4212, the support flange 4213, and the outer barrier wall 4214 can be formed in one piece.

[0051] The annular main body 4212 is arranged on an inner side of the entire carrier 421 to support the coil 422. In particular, a cross-section of the annular main body 4212 perpendicular to the radial direction of the annular shape coincides with the coil 422. The coil 422 is arranged at an end of the annular main body 4212 facing the interior of the core housing, and an inner side wall and an outer side wall of the annular main body 4212 can each be flush with an inner side wall and an outer side wall of the coil 422, such that the inner side wall of the coil 422 is coplanar with the inner side wall of the annular main body 4212 and the outer side wall of the coil 422 is coplanar with the outer side wall of the annular main body 4212.

[0052] Furthermore, it is provided that the support flange 4213 is arranged projecting from the outer side wall of the annular main body 4212 and extends outwards from the annular main body 4212. In particular, it can extend outwards in a direction perpendicular to the outer side wall of the annular main body 4212. The support flange 4213 can be arranged in a position between two ends of the annular main body 4212. In the present embodiment, the support flange 4213 can project circumferentially around the outer side wall of the annular main body 4212 and thus constitute an annular support flange 4213. In another embodiment, the support flange can also be designed such that it projects from the outer side wall of the annular main body 4212 only in certain positions, as required.

[0053] The outer barrier wall 4214 is connected to the support flange 4213 and is arranged laterally to the annular main body 4212, spaced apart from it. The outer barrier wall 4214 can be spaced apart and peripherally mounted on the annular main body 4212 and / or the coil 422. In particular, depending on the actual requirements, it can be mounted partially peripherally on the annular main body 4212 and the coil 422, and partially peripherally on the annular main body 4212. It should be noted that in the present embodiment, a portion of the outer barrier wall 4214, located near the cable tray 4211, is mounted peripherally on a portion of the annular main body 4212. Specifically, the outer barrier wall 4214 is arranged on a side of the support flange 4213 that is further away from the core housing.The outer side wall of the ring-shaped main body 4212, the side wall of the support flange 4213 which is further away from the core housing and the inner side wall of the outer barrier wall 4214 together define the cable tray 4211.

[0054] In one embodiment, the annular main body 4212 and the support flange 4213 are provided with wiring channels 424. The internal guide line 423 extends through the wiring channel 424 into the cable tray 4211.

[0055] The wiring channel 424 comprises a partial wiring channel 4241 on the annular main body 4212 and a partial wiring channel 4242 on the support flange 4213. The partial wiring channel 4241 extends through the inner and outer side walls of the annular main body 4212 and is provided on a side of the annular main body 4212 located near the coil 422 with a wiring opening 42411 connected to one end of the partial wiring channel 4241, and on a side located near the support flange 4213, facing the interior of the core housing, with a wiring opening 42412 connected to the other end of the partial wiring channel 4241.The partial wiring channel 4242 extends through the support flange 4213 in a direction pointing outwards from the core housing and is provided on one side of the support flange 4213 facing the interior of the core housing with a wiring opening 42421 connected to one end of the partial wiring channel 4242, and on a side further away from the interior of the core housing with a wiring opening 42422 connected to the other end of the partial wiring channel 4242. The wiring opening 42412 and the wiring opening 42421 are connected to each other via a space between the support flange 4213 and the annular main body 4212.

[0056] Furthermore, it is provided that the internal guide line 423 can enter the wiring opening 42411, extends along the partial wiring channel 4241, protrudes from the wiring opening 42412, and thus enters the area between the annular main body 4212 and the support flange 4213. The internal guide line then enters the partial wiring channel 4242 via the wiring opening 42421 and, after protruding from the wiring opening 42422, extends into the cable tray 4211.

[0057] In one embodiment, a slot 42141 is provided at an upper end of the outer barrier wall 4214, wherein the external line 48 can extend through the slot 42141 into the cable tray 4211.

[0058] In this arrangement, one end of the external line 48 is arranged on the flexible circuit board 44, the flexible circuit board 44 being arranged in particular on a side of the earphone core facing the interior of the core housing.

[0059] In the present embodiment, the support flange 4213 extends to a side of the outer barrier wall 4214 further away from the annular main body 4212, in order to form an outer edge. Furthermore, the outer edge is designed to abut the inner side wall of the core housing all around. In particular, the outer edge of the support flange 4213 is provided with a slot 42131, so that the external conductor 48, located on a side of the earphone core facing the interior of the core housing, can extend through the slot 42131 to a side of the support flange 4213 facing the outside of the core housing, and thus to the slot 42141, and enters the cable channel 4211 through the slot 42141.

[0060] Furthermore, it is provided that a guide groove 416 is provided on the inner side wall of the core housing, extending outwards from the core housing and with one end located on one side of the soft circuit board 44 and the other end connected to the slot 42131, so that the external line 48 extends via the guide groove 416 from the soft circuit board to a second wiring groove 3331.

[0061] In one embodiment, the support 421 further comprises two lateral barrier walls 4215, which are spaced apart from one another on the circumference of the annular main body 4212 and connect the annular main body 4212, the support flange 4213 and the outer barrier wall 4214. This defines the cable tray 4211 between the two lateral barrier walls 4215.

[0062] In particular, the two lateral barrier walls 4215 are arranged opposite each other on the support flange 4213 and project from one side of the support flange 4213 facing the outside of the core housing. The sides of the two lateral barrier walls 4215 facing the annular main body 4212 are connected to the outer side wall of the annular main body 4212, and the sides further away from the annular main body 4212 terminate at the outer side wall of the outer barrier wall 4214. Furthermore, the wiring opening 42422 and the slot 42141 are defined between the two lateral barrier walls 4215. As a result, the internal guide line 423 protruding from the wiring opening 42422 and the external line 48 entering via the slot 42141 extend into the cable tray 4211 defined by the two lateral barrier walls 4215.

[0063] Fig. Figure 7 shows a schematic structural representation of a loudspeaker according to some embodiments of the present application.

[0064] In some embodiments, the loudspeaker may be a pair of glasses. In some embodiments, the fastening mechanism may be a pair of glasses. The fastening mechanism may include at least one rotating shaft assembly used to connect a frame to a temple. The frame and temple are rotatable about the rotating shaft assembly. The rotating shaft assembly is axially provided with a wiring channel. The fastening mechanism may be provided with a connecting wire, which is an electrical connecting wire. The connecting wire passes through the wiring channel, and its two ends extend into the frame and temple, respectively.In some embodiments, a control circuit and a battery assembly can be accommodated on two sides of the temples of the spectacles, with the connecting wire in the spectacle frame electrically connecting the control circuit to the battery assembly. The connecting wire can be an audio signal line or an auxiliary signal line. The connecting wire can be electrically connected to the flexible circuit board (i.e., flexible circuit board 106) in the core housing (i.e., core housing 108) and, via the flexible circuit board, to the earphone core (i.e., earphone core 102) and the auxiliary function module (i.e., auxiliary function module 104).

[0065] In some embodiments, the glasses of the present application may be glasses worn in daily life and work processes to correct vision and protect the eyes. Alternatively, a specific circuit structure, an electronic element, etc., is added to the above glasses to create glasses with a specific function. In particular, the glasses of the present application may be smart glasses, virtual reality glasses, holographic glasses, augmented reality glasses, or glasses with another functional structure (such as glasses with a bone conduction earphone or an air conduction earphone).

[0066] As in Fig. As shown in Figure 7, in some embodiments the spectacle frame may comprise the following: a spectacle frame 11, a nose pad 12, a spectacle lens 13 and spectacle temples 15.

[0067] The spectacle frame 11 serves to support at least part of the spectacle lens 13. The nose pad 12 serves to support the spectacles on the bridge of the user's nose when worn by the user.

[0068] The nose pad 12 is located in the center of the spectacle frame 11 and is formed integrally with the frame. In the prior art, the spectacle frame 11 and the nose pad 12 are typically formed separately, with a structure connected to the nose pad 12 located in the center of the frame. After forming, the nose pad 12 is mounted in the connecting structure of the frame. In the present embodiment, however, the spectacle frame 11 and the nose pad 12 are directly formed integrally. In particular, they can be formed integrally using a suitable mold, injection molding, or the like. After forming the spectacle frame 11 and the nose pad 12 in the present embodiment, no further assembly is required, thus simplifying the manufacturing process.

[0069] Furthermore, the spectacle lens 13 can also be formed in one piece. In addition, the spectacle lens 13 is attached to the spectacle frame 11 and the nose pad 12 by means of a snap-fit ​​connection.

[0070] Furthermore, it is provided that the spectacle frame 11 and the nose pad 12 are each equipped with a structure for snap-fit ​​connection to the spectacle lens 13. During assembly of the spectacles, it is sufficient to achieve the snap-fit ​​connection of the one-piece spectacle lens 13 to the spectacle frame 11 and the nose pad 12, which are formed in one piece, directly by means of a corresponding snap-fit ​​structure.

[0071] In the above embodiment, the spectacle frame 11 and the nose pad 12 are formed in one piece and the spectacle lens 13 is also formed in one piece, so that the spectacles have a simple structure and the process for manufacturing the spectacles can be simplified.

[0072] See more Fig. 7. Fig. Figure 7 shows an exploded view of an embodiment of the spectacles of the present application. In the present embodiment, the spectacle lens 13 comprises an upper edge 131 and two outer edges 132, which are connected to two ends of the upper edge 131 and are arranged further away from the nose pad 12, each of the outer edges 132 being provided with a first snap-in point 1321 projecting forward. The spectacle frame 11 is provided with a first mounting groove 111, through which the upper edge 131 and at least partially the outer edges 132 are received, and a first snap-in groove 112, which is connected to the first mounting groove 111 and serves to receive the first snap-in point 1321.

[0073] When the glasses are worn, the upper edge 131 rests on the top of the lens 13, the outer edges are located on two sides of the lens 13 closest to the user's ears, and the upper edge 131 is connected to the two outer edges 132. The first mounting groove 111 is provided on a side of the frame 11 facing the lens 13, and its dimensions correspond to the upper edge 131 and the two outer edges 132 of the lens 13, so that the lens 13 can be mounted on the frame 11 by fitting the upper edge 131 and at least part of the outer edges 132 into the first mounting groove 111.

[0074] Furthermore, the first locking point 1321 is formed by the outer edges 132 of the spectacle lens 13 extending at least partially to two sides further away from the nose pad 12. The first locking groove 112, on the other hand, is formed by a corresponding recess in the first mounting groove 111, pointing away from the spectacle lens 13. The shape and dimensions of the first locking groove 112 match the first locking point 1321, so that the spectacle lens 13 can be mounted on the spectacle frame 11 by further engaging the first locking point 1321 in the first locking groove 112.

[0075] It should be noted that the outer edge 132 is located at least partially on a side of the first locking point 1321 that is further away from the upper edge 131, so that the spectacle lens 13, which lies near two sides of the first locking point 1321 along the edge of the spectacle lens 13, is received in the first mounting groove 111 and thus the spectacle lens 13 can be attached more firmly to the spectacle frame 11.

[0076] In one embodiment, the spectacle lens 13 further comprises inner edges 133 that abut the nose pad 12. The nose pad 12 is provided with a second mounting groove 121 for receiving the inner edge 133.

[0077] It should be noted that the spectacle lens 13 comprises a left and a right spectacle lens. The inner edges 133 of the spectacle lens 13 are provided at the junctions of the left and right spectacle lenses and in the vicinity of these junctions. Accordingly, the second mounting groove 121 is arranged opposite the first mounting groove 111, so that two opposite sides of the spectacle lens 13 are each received and secured in a receiving space formed by the spectacle frame 11 and the nose pad 12.

[0078] In one embodiment, two sides of the inner edges 133 are each provided with a second locking point 1331 projecting from the outside. The nose pad 12 is further provided with a second locking groove 122, which is connected to the second mounting groove 121 and serves to receive the second locking point 1331.

[0079] The inner edges 133 comprise two interconnected parts, each located on a side of the left lens facing the right lens and on a side of the right lens facing the left lens. The nose pad 12 is also divided into two parts, which, when worn, are supported by the user against the left and right bridges of the nose, respectively. Accordingly, the present embodiment provides two secondary locking grooves 122 and two secondary locking points 1331. The shape and dimensions of the secondary locking point 1331 match the corresponding secondary locking groove 122, enabling the secondary locking point 1331 to be mounted into the respective secondary locking groove 122.

[0080] In addition, the spectacle lens 13 is provided with inner edges 133 near two sides of the second locking point 1331, so that the adjacent points of the two sides of the second locking point 1331 can be mounted in the second mounting groove 121 in order to attach the spectacle lens 13 more firmly to the nose pad 12.

[0081] In the above manner, the spectacle lens 13 is mounted on the spectacle frame 11 and nose pad 12 by the upper edge 131, the outer edges 132, the inner edges 133, as well as the first locking point 1321 and the second locking point 1331.

[0082] In one application scenario, the spectacle lens 13 is further provided with a ventilation opening 134. In particular, two ventilation openings can be provided, each located near the upper edge 131 of the left and right spectacle lens 13. The provision of the ventilation opening 134 allows the user to ventilate the inner and outer surfaces of the spectacle lens 13 while wearing the glasses, thus reducing the phenomenon of fogging of the spectacle lens 13 due to local overheating caused by user movement or the like.

[0083] See further and together Fig. 7 and Fig. 8. In particular, it is provided that Fig. 7 an exploded view of the loudspeaker according to some embodiments of the present application and Fig. Figure 8 shows a schematic structural representation of a nose pad cover in an embodiment of the spectacles of the present application. In one embodiment, the nose pad 12 comprises a connecting part 123, which, when worn, is connected to the spectacle frame 11 at a side near the user or at a side of the first mounting groove 111 further away from the user, and two support parts 124, which are connected to the connecting part 123 in an inverted Y-shape at a side of the connecting part 123 further away from the spectacle frame 11. The support parts 124 serve to support the spectacles on the bridge of the user's nose when worn.

[0084] In one application scenario, the connecting part 123 is integrally connected to the spectacle frame 11, and when worn by the user, the connecting part 123 is located on a side of the first mounting groove 111 that is close to the user.

[0085] Each support element 124 is provided on one side facing the bridge of the user's nose with an I-shaped locking hook 1241. The glasses may further include a nose pad cover 14 that is detachably attached to the locking hook 1241.

[0086] The nose pad cover 14 can be made of soft rubber. In particular, two I-shaped locking hooks 1241 can be provided, each corresponding to the left and right bridge of the user's nose. The nose pad cover 14 comprises two cover bodies 141 and connecting parts 142 connecting the two cover bodies 141 to each other, the connecting parts 142 being connected to each other above the bridge of the user's nose. The cover body 141 is accordingly provided with an I-shaped receiving groove 1411 that fits the locking hook 1241. In addition, a non-slip part 1412 consisting of several recesses can be provided on a side of the cover body 141 facing the bridge of the user's nose. In the present embodiment, the nose pad cover 14 is designed to be detachable in order to facilitate cleaning and replacement of the nose pad cover 14.

[0087] Furthermore, it is provided that in one embodiment the sides of the two support parts 124 facing away from the locking hook 1241 are provided with strip-shaped ribs 1242, wherein the strip-shaped ribs 1242 fit the two support parts 124 to form the second mounting groove 121 and the second locking groove 122.

[0088] The strip-shaped ribs 1242 are arranged projecting along the edges of the two support parts 124 furthest from the spectacle lens 13, in order to form the second mounting groove 121 for receiving the inner edges 133 of the spectacle lens 13. At a point corresponding to the second locking point 1331 of the spectacle lens 13, the strip-shaped ribs 1242 are further recessed and thus form the second locking groove 122.

[0089] See together Fig. 7. In one embodiment, the spectacle frame further comprises temples 15, functional arrangements 16, and a connecting wire 17. The temples 15 comprise a first temple 151 and a second temple 152. The functional arrangements 16 comprise a first functional arrangement 161 and a second functional arrangement 162.

[0090] In particular, the first temple 151 and the second temple 152 are each connected to the spectacle frame 11. The first functional arrangement 161 is arranged on the first temple 151, and the second functional arrangement 162 is arranged on the second temple 152. Each of the two temples 15 has at least one chamber to accommodate the respective functional arrangements 16.

[0091] The connecting wire 17 is arranged in the first mounting groove 111, is located between the underside of the first mounting groove 111 and the top edge 131 of the spectacle lens 13 and extends further to the first temple 151 and second temple 152 to electrically connect the first functional arrangement 161 with the second functional arrangement 162.

[0092] In the present embodiment, the functional arrangements 16, each located in the two temples 15 of the glasses, must be electrically connected to one another via the connecting wire 17 so that the glasses perform a specific function. In particular, one application scenario provides that the first functional arrangement 161 is a battery arrangement and the second functional arrangement 162 is a control circuit arrangement, wherein the control circuit arrangement is connected to the battery arrangement via the connecting wire 17, so that the battery arrangement supplies the control circuit arrangement with current and thus the control circuit arrangement performs a specific function.

[0093] To meet the aesthetic and lightweight requirements of the spectacles, the connecting wire 17 is arranged along the upper edge 131 of the lens 13 in the first mounting groove 111 and is contained within a space formed by the first mounting groove 111 and the upper edge 131 of the lens 13, so that the connecting wire 17 is neither exposed from the outer surface of the spectacles nor occupies any additional space. In one application scenario, the connecting wire 17 can also extend further within the first mounting groove 111 along the outer edge 132 of the lens 13.

[0094] In particular, the spectacle frame 11 can further be provided with wiring channels, each connected to the first temple 151 and the second temple 152, so that the connecting wire 17 can enter the first temple 151 and the second temple 152 via respective wiring channels from the first mounting groove 111 of the spectacle frame 11, thus connecting the first functional arrangement 161 with the second functional arrangement 162.

[0095] In the present embodiment, the connecting wire 17 has the function of an electrical connection. In another embodiment, the connecting wire 17 can also have the function of a mechanical connection.

[0096] In the embodiment described above, the first functional arrangement 161 is located on the first temple 151 and the second functional arrangement 162 on the second temple 152. The connecting wire 17 for the electrical connection of the first functional arrangement 161 to the second functional arrangement 162 is located in the first mounting groove 111 on the spectacle frame 11, which serves to receive the upper edge 131 of the spectacle lens 13. This allows the connecting wire 17 to extend between the underside of the first mounting groove 111 and the upper edge 131 of the spectacle lens and further to the first temple 151 and second temple 152, so that the connecting wire 17 is not exposed and no additional space needs to be added for it, thus maintaining the aesthetics and low weight of the spectacles.

[0097] See further and together Fig. 9, Fig. 10 and Fig. 11. Fig. Figure 9 shows a partially cutaway, schematic representation of the spectacle frame and the spectacle lens in an embodiment of the spectacles of the present application. Fig. Figure 10 shows an enlarged view of part A from Fig. 9, and Fig. Figure 11 shows a schematic structural section of the connecting wire in an embodiment of the glasses of the present application. In the present embodiment, the connecting wire 17 comprises a wire body 171 and a wire sheath 172, which peripherally encloses the wire body 171. The cut shape of the wire sheath 172 matches the cut shape of the first mounting groove 111 in order to hold the wire sheath 172 in planar contact within the first mounting groove 111.

[0098] The wire protection sleeve 172 is made of soft rubber, allowing the connecting wire 17 to bend to fit the shape of the first mounting groove 111. It is easy to understand that the wire body 171 itself is thin. If the wire body is mounted directly in the first mounting groove 111, the contact area with the underside of the first mounting groove 111 is small, making it difficult to securely fasten the wire body in the first mounting groove. In the present embodiment, the wire body 171 is further provided peripherally with an enveloping wire protection sleeve 172. This protects the wire body 171 and allows the contact area of ​​the connecting wire 17 with the first mounting groove 111 to be increased by adjusting the surface of the wire protection sleeve 172, thus ensuring the wire body 171 is securely fastened in the first mounting groove 111.

[0099] Furthermore, the cross-sectional shape of the first mounting groove 111 is designed such that the wire protection sleeve 172 can be held in the first mounting groove 111 with relatively large contact areas. For example, it can be U-shaped, rectangular, or corrugated, etc., although this is not specifically defined here. Accordingly, the shape of the wire protection sleeve 172 on one side facing the underside of the first mounting groove 111 corresponds to the shape described above, so that the wire protection sleeve 172 can bear directly or indirectly against the underside of the first mounting groove 111.

[0100] See more Fig. 7. In one application scenario, an adhesive layer 18 is provided between the wire protection sleeve 172 and the spectacle frame 11 in order to attach the wire protection sleeve 172 in the first mounting groove 111 by means of the adhesive layer 18.

[0101] The adhesive layer 18 can be provided on the underside of the first mounting groove 111 and it can also extend further on two sides and thus be provided on side walls near the underside of the first mounting groove 111, so that the adhesive layer 18 encases the wire protection sleeve 172 in order to fix the connecting wire 17 more firmly in the first mounting groove 111.

[0102] In the present application scenario, the cross-section of the first mounting groove 111 is specifically rectangular. The underside of the first mounting groove 111 and a side of the wire protection sleeve 172 facing the underside of the first mounting groove 111 are formed flat. The adhesive layer 18 is a double-sided adhesive layer between the two.

[0103] Furthermore, in one embodiment, a side of the wire protective sleeve 172 facing the upper edge 131 of the spectacle lens 13 is provided with a projection 1721 corresponding to the wire body 171. A clearance groove 1311 is provided at the upper edge 131 of the spectacle lens 13 to accommodate the projection 1721.

[0104] In particular, the cross-section of the wire body 171 can be circular. The wire protective sleeve 172 can be flush with the wire body 171 on one side facing the underside of the first mounting groove 111, but on one side facing away from the underside of the first mounting groove 111, it can still retain the shape of the wire body 171, so that the corresponding projection 1721 is formed.

[0105] Furthermore, it is provided that the upper edge 131 of the spectacle lens 13 must be positioned further within the first mounting groove 111. In the present embodiment, a clearance groove 1311 for receiving the projection 1721 is also provided on the upper edge 131, so that the connecting wire 17 installed in the first mounting groove 111 is at least partially received in the corresponding clearance groove 1311 of the upper edge 131.

[0106] Furthermore, it is provided that the projection 1721 is located in a central region of the wire protective sleeve 172 in a lateral direction, in order to form contact elements 1722 on two sides of the projection 1721, wherein the two contact elements 1722 each abut the upper edge 131 on two sides of the clearance groove 1311. The lateral direction of the wire protective sleeve 172 refers to a direction that is perpendicular to the course of the wire protective sleeve 172 along the first mounting groove 111, in particular as defined by W in Fig. 10 indicated direction.

[0107] It is easy to understand that the depth of the first mounting groove 111 is limited. If the upper edge 131 of the spectacle lens 13 is flush with the projection 1721 of the connecting wire 17, or if the wire guard 172 is flush with one side of the wire body 171 facing away from the underside of the first mounting groove 111, the insertion depth of the upper edge 131 of the spectacle lens 13 into the first mounting groove 111 is reduced, which is detrimental to the stable mounting of the spectacle lens 13 in the spectacle frame 11. In the present embodiment, the upper edge 131 of the spectacle lens 13 has moved away from a part of the connecting wire 17 via the clearance groove 1311, so that the upper edge 131 can extend further towards the underside of the first mounting groove 111 relative to the clearance groove 1311 and can abut the contact parts 1722 on the two sides of the projection 1721.This allows the space occupied by the connecting wire 17 in the first mounting groove 111 to be reduced to some extent, so that the spectacle lens 13 can be mounted deeper in the first mounting groove 111 and thus the stability for mounting the spectacle lens 13 in the spectacle frame 11 is increased.

[0108] In one application scenario, the spectacle frame 11 is relatively thin and the projection 1721 extends at least partially from the first mounting groove 111 to reduce the space occupied by the connecting wire 17 in the spectacle frame, to decrease the depth of the first mounting groove 111 and to increase the stability of the spectacle frame 11.

[0109] See further Fig. 2 or 12. Fig. Figure 12 shows a schematic structural section of part B from Fig. 7. In one embodiment, the first locking point 1321 comprises a first partial edge 13211, a second partial edge 13212 and a third partial edge 13213.

[0110] The first partial edge 13211 is located adjacent to the upper edge 131. The second partial edge 13212 is further away from the upper edge 131 and lies opposite the first partial edge 13211. The third partial edge 13213 connects the first partial edge 13211 with the second partial edge 13212 on a side of the first partial edge 13211 and the second partial edge 13212 that is further away from the lens 13.

[0111] In the present embodiment, the wire protection sleeve 172 extends further along the first partial edge 13211 into the first snap-in groove 112.

[0112] In the above manner, the wire protection sleeve 172 is held in the first mounting groove 111 and extends to the first locking groove 112 to be concealed in the spectacle frame 11, so that when the spectacle lens 13 is disassembled by the user during use, the wire protection sleeve 172 cannot be exposed after the spectacle lens 13 has been disassembled, thus maintaining the aesthetics of the spectacles.

[0113] Furthermore, it is provided that the wire protective sleeve 172 terminates at a junction of the first partial edge 13211 and the third partial edge 13213 as it extends to the first locking groove 112. Of course, the wire protective sleeve 172 may also not terminate but continue to extend with the wire body 171, provided that the wire protective sleeve 172 cannot be exposed during the removal of the spectacle lens 13.

[0114] See further and together Fig. 13. Fig. Figure 13 shows an enlarged sectioned structural detail of an embodiment of the glasses of the present application. The glasses in the present embodiment further comprise a rotating shaft arrangement 19.

[0115] Two rotating shaft assemblies 19 are provided, which are used to connect the spectacle frame 11 to two temples 15, so that the spectacle frame 11 and the temples 15 can be rotated relative to each other about the rotating shaft assemblies 19. The rotating shaft assembly 19 is axially provided with a rotating shaft wiring channel 1901, wherein the connecting wire 17 is passed through the rotating shaft wiring channel 1901 and extends to the spectacle frame 11 and to the temples 15, respectively.

[0116] In particular, in the present embodiment, the connecting wire 17 is provided such that, after passing through the rotary shaft wiring channel 1901, one end of the connecting wire extends directly to a temple 15 and the other end enters the spectacle frame 11 and extends along the first mounting groove 111 further to the other temple 15 in order to electrically connect with two respective functional arrangements 16 in the two temples 15.

[0117] In the present embodiment, the connecting wire 17 may not be provided with a wire protection sheath 172 in the vicinity of the rotary shaft wiring channel. The rotary shaft wiring channel 1901 may pass through the rotary shaft assembly 19.

[0118] It is easy to understand that when bending occurs between the spectacle frame 11 and the temple 15, the relative positions of the structures near the rotating shaft assembly 19 can change. If the connecting wire 17 is located directly peripherally around the rotating shaft assembly 19 at the connection point between the spectacle frame 11 and the temple 15, the connecting wire 17 will be pressed or pulled, and even deformed or broken, when the spectacle frame 11 or the temple 15 is folded. This affects the stability of the connecting wire 17 and reduces its service life.

[0119] In the present embodiment, the rotating shaft assembly 19 is axially provided with a rotating shaft wiring channel 1901, and the connecting wire 17 at the connection point of the spectacle frame 11 with the temple 15 is located entirely inside the rotating shaft wiring channel 1901. This means that when the spectacle frame 11 is folded relative to the temple 15, the connecting wire 17 in the rotating shaft wiring channel 1901 is subject only to a certain degree of rotation with the rotation of the rotating shaft assembly 19, in order to reduce folding, pressing, or pulling of the connecting wire 17. This protects the connecting wire 17 to a certain extent, increases its stability, and extends its service life.

[0120] In the present embodiment, the inner diameter of the rotating shaft wiring channel 1901 is larger than the outer diameter of the connecting wire 17. For example, the inner diameter of the rotating shaft wiring channel 1901 can be twice the outer diameter of the connecting wire 17. This reduces the limiting effect on the connecting wire 17 by the inner side wall of the rotating shaft wiring channel 1901, thereby reducing the amplitude of the rotation of the connecting wire 17 when the spectacle frame 11 is folded relative to the temple 15.

[0121] See further and together Fig. 13 and Fig. 14. Fig. Figure 14 shows a schematic structural representation of the rotating shaft arrangement and the connecting wire in an embodiment of the spectacles of the present application. In the present embodiment, the rotating shaft arrangement 19 comprises a first rotating shaft 1902, wherein two ends of the first rotating shaft 1902 are each connected to the spectacle frame 11 and the spectacle temple 15, respectively, wherein the rotating shaft wiring channel 1901 extends in the axial direction of the first rotating shaft 1902, wherein the rotating shaft wiring channel 1901 is connected to the external environment via a wiring opening 19021 provided on at least one end face of the first rotating shaft 1902, and wherein the connecting wire 17 extends through the wiring opening 19021 to the spectacle frame 11 and spectacle temple 15.

[0122] It should be noted that in the present embodiment the first rotating shaft 1902 can be rotatably connected to one of the spectacle frame 11 and the spectacle temple 15 and fixedly connected to the other of them in order to rotatably connect the spectacle frame 11 and the spectacle temple 15 about the first rotating shaft 1902.

[0123] In particular, the present embodiment provides that the rotary shaft wiring channel 1901 is provided in the first rotary shaft 1902 and is further connected to the external environment through the wiring opening 19021.

[0124] In particular, the rotary shaft wiring channel 1901 passes through at least one end face of the first rotary shaft 1902 and thus forms the wiring opening 19021 of the rotary shaft wiring channel 1901, so that the connecting wire 17 can extend from the rotary shaft wiring channel 1901 beyond the at least one end face of the first rotary shaft 1902 and thus to the spectacle frame 11 or temple 15. It is easy to understand that the end face of the first rotary shaft 1902 has a large peripheral space for movement, and the connecting wire 17 extending from the end face of the first rotary shaft 1902 can be accommodated within this space.If the first pivot shaft 1902 is rotatably connected to the corresponding spectacle frame 11 or temple 15 at the end face, and thus the spectacle frame 11 is folded or rotated relative to the temple 15, adequate damping over the range of motion can be achieved if the connecting wire 17 near the wiring opening 19021 in the end face is twisted to a certain degree by the rotation of the first pivot shaft 1902. Furthermore, the twist can be converted into movement, so that the degree of twist of the connecting wire 17 is further reduced and the stability of the connecting wire 17 is increased.

[0125] See Fig. 15. Fig. Figure 15 shows a schematic structural representation of the first rotating shaft of an embodiment of the spectacles of the present application. In the present embodiment, the wiring openings 19021 comprise a first wiring opening 190211 and a second wiring opening 190212 and are provided in two end faces of the first rotating shaft 1902. The rotating shaft wiring channel 1901 is connected to the external environment through the two wiring openings 19021, such that the connecting wire 17 passes through two end faces of the first rotating shaft 1902 and extends through the first wiring opening 190211 and the second wiring opening 190212, respectively, to the spectacle frame 11 and temple 15.

[0126] This means that, in the present application scenario, the connecting wire 17 is arranged at the connection point between the spectacle frame 11 and the temple 15 in the rotating shaft wiring channel 1901 of the first rotating shaft 1902 and extends from the rotating shaft wiring channel 1901 through each of the two end faces of the first rotating shaft 1902. Because the two end faces of the first rotating shaft 1902 have large peripheral clearances, the connecting wire 17 extending from the two end faces of the first rotating shaft 1902 does not experience any deformation from pushing or pulling, but only movement or rotation with a small amplitude when the spectacle frame 11 is rotated relative to the temple 15.

[0127] See further Fig. 14. In the present embodiment, the wiring openings 19021 comprise a first wiring opening 190213 and a second wiring opening 190214. The first wiring opening 190213 is located in an end face of the first rotating shaft 1902, and the second wiring opening 190214 is located in a side wall of the first rotating shaft 1902, such that one end of the rotating shaft wiring channel 1901 passes axially through the first wiring opening 190213 through the end face of the first rotating shaft 1902, and the other end passes through the second wiring opening 190214 through the side wall of the first rotating shaft 1902, thus connecting to the external environment. The connecting wire 17 extends through the first wiring opening 190213 and the second wiring opening 190214, respectively, to the spectacle frame 11 and temple 15.

[0128] Likewise, there is a large range of motion at the end face of the first rotating shaft 1902, which is provided with the first wiring opening 190213. When the spectacle frame 11 moves relative to the temple 15, the connecting wire 17 near the first wiring opening 190213 is subject only to relative movement or rotation with a small amplitude.

[0129] In one application scenario, the first rotating shaft 1902 is rigidly connected to one of the spectacle frame 11 or temple 15 located near the second wiring opening 190214, while the first rotating shaft is rotatably connected to the other of the spectacle frame 11 or temple 15 located near the first wiring opening 190213. That is, the first rotating shaft 1902 is rotatably connected to one of the spectacle frame 11 or temple 15 at the wiring opening 19021 provided in the end face, while the first rotating shaft 1902 is rigidly connected to the other of the spectacle frame 11 or temple 15 at the wiring opening 19021 provided in the side wall.

[0130] In one application scenario, the first rotating shaft 1902 is located at the first wiring opening 190213 near the spectacle frame 11 and is rotatably connected to the spectacle frame 11, while the first rotating shaft 1902 is located at the second wiring opening 190214 near the temple 15 and is fixedly connected to the temple 15.

[0131] It should be noted that in the present application scenario, although the first rotating shaft 1902 is rotatably connected to the spectacle frame 11, and the connecting wire 17 is set into relative motion at the first wiring opening 190213 when the spectacle frame 11 is rotated relative to the temple 15, the fact that the first wiring opening 190213 is provided in the end face of the first rotating shaft 1902 means that, analogous to the embodiment described above, there is a large range of motion at the end face of the first rotating shaft 1902. When the spectacle frame 11 is folded or rotated relative to the temple 15, adequate damping can be achieved over this range of motion if the connecting wire 17 is twisted to some extent near the wiring opening 19021 in the end face as the first rotating shaft 1902 rotates.Furthermore, the twisting can be converted into movement or twisting with low amplitude without pushing or pulling the connecting wire, thus increasing the stability of the connecting wire and extending its service life.

[0132] Furthermore, the first rotating shaft 1902 is fixedly connected to the temple 15 at the second wiring opening 190214. It is easy to understand that when the spectacle frame 11 moves relative to the temple 15, the temple 15 is held synchronously with the first rotating shaft 1902, so that the connecting wire 17 in the rotating shaft wiring channel 1901, or the connecting wire 17 extending through the second wiring opening 190214 into the temple 15, is not twisted, pushed, or pulled. Therefore, the rotation of the spectacle frame 11 relative to the temple 15 does not cause the aforementioned twisting, pushing, pulling, or similar action on the connecting wire 17, regardless of whether the second wiring opening 190214 is located in the end face of the first rotating shaft 1902 or in the side wall of the first rotating shaft 1902.

[0133] In another embodiment, however, it is provided that the connecting wire 17 is restricted by the side wall of the first rotating shaft 1902 at the second wiring opening 190214 and is thus pressed through the side wall of the first rotating shaft 1902 and the temple 15 when the first rotating shaft 1902 is rotatably connected to the temple 15 at the second wiring opening 190214 and the relative rotation of the two sets the connecting wire 17 in motion.

[0134] If the first rotating shaft 1902 is located at the first wiring opening 190213 near the temple 15 and is rotatably connected to the temple 15, and if the first rotating shaft 1902 is located at the second wiring opening 190214 near the frame 11 and is fixedly connected to the frame 11, then when the frame 11 is folded relative to the temple 15, the connecting wire 17 in the rotating shaft wiring channel 1901 and near the first wiring opening 190213 and the second wiring opening 190214 is only twisted or moved to a small amplitude.

[0135] See further Fig. 14. In one embodiment, the rotary shaft arrangement 19 further comprises a second rotary shaft 1903, which is arranged coaxially to and spaced apart from the first rotary shaft 1902.

[0136] In the present embodiment, the second rotating shaft 1903 is arranged on a side of the first rotating shaft 1902 located near the first wiring opening 190213. In another embodiment, the second rotating shaft 1903 can of course also be arranged on a side of the first rotating shaft 1902 located near the second wiring opening 190214.

[0137] See more Fig. 16. Fig. Figure 16 shows an exploded section of an embodiment of the spectacles of the present application. In the present embodiment, the spectacle frame 11 comprises a first tab 113. In particular, two first tabs 113 are provided, which are arranged at two ends of the spectacle frame 11 connected to two temples 15 and project towards the respective temples 15.

[0138] The temple 15 comprises a second tab 1501 and a third tab 1502, which are spaced apart from each other. The second tab 1501 and the third tab 1502 are oriented towards one end of the spectacle frame 11, to which the temple 15 is connected. When the user wears the glasses, the second tab 1501 and the third tab 1502 are connected to each other on a side further away from the user's head, to enhance the overall appearance and aesthetics of the glasses. In one application scenario, the spaced-apart second tab 1501 and the third tab 1502 are designed by having a recess in the center of one end of the temple 15 facing the spectacle frame 11.

[0139] Furthermore, it is provided that the ends facing each other of the first rotating shaft 1902 and the second rotating shaft 1903 are connected to the first tab 113, and that the ends facing away from each other of the first rotating shaft 1902 and the second rotating shaft 1903 are each connected to the second tab 1501 and the third tab 1502 respectively, in order to hold the first tab 113 between the second tab 1501 and the third tab 1502.

[0140] See further Fig. 14. In one embodiment, the first wiring opening 190213 is provided in an end face of the first rotating shaft 1902 located near the second rotating shaft 1903, and the second wiring opening 190214 is provided in a side wall of the first rotating shaft 1902 located near the second tab 1501, wherein the first rotating shaft 1902 is rotatably connected to the first tab 113 and fixedly connected to the second tab 1501.

[0141] In particular, the present embodiment provides that one end of the connecting wire 17 extends in the rotating shaft wiring channel 1901 from the first wiring opening 190213 and beyond the distance between the first rotating shaft 1902 and the second rotating shaft 1903. Furthermore, in one application scenario, the first tab 113 is provided with a wiring channel connected to the first wiring opening 190213, so that the connecting wire 17 enters the spectacle frame 11 further from the first tab 113.

[0142] Furthermore, the other end of the connecting wire 17 extends beyond the second wiring opening 190214 in the rotating shaft wiring channel 1901. It is also provided that, in one application scenario, the third tab 1502 is provided with a wiring channel connected to the second wiring opening 190214, so that the connecting wire 17 can enter the temple 15 via the wiring channel of the third tab 1502.

[0143] The second wiring opening 190214 can be configured as a through-hole provided in the side wall of the first rotating shaft 1902, which does not extend through the end of the first rotating shaft 1902 and is connected to the rotating shaft wiring channel 1901. In the present embodiment, the second wiring opening 190214 extends further along the side wall of the first rotating shaft 1902 and passes through the end of the first rotating shaft 1902 that is further away from the first wiring opening 190213. It is easy to understand that in the present embodiment, there is a larger space at the second wiring opening 190214, so that the constraint on the connecting wire 17 during its movement can be further reduced for several reasons, thus further mitigating damage caused by the obstruction of the side wall of the first rotating shaft 1902.

[0144] See further and together Fig. 16, Fig. 17 and Fig. 18. Fig. Figure 17 shows a schematic structural representation of the spectacle frame and the spectacle lens in an embodiment of the spectacles of the present application, and Fig. Figure 18 shows a schematic structural section of the temple of an embodiment of the spectacles of the present application. In the present embodiment, the first tab 113 and the second tab 1501 are provided coaxially with a first receiving bore 1131 and a second receiving bore 15011, respectively, wherein the first receiving bore 1131 and the second receiving bore 15011 are dimensioned such that the first pivot shaft 1902 can be inserted from the outside of the temple 15 through the second receiving bore 15011 into the first receiving bore 1131, and that the first pivot shaft 1902 is in an interference fit with the second receiving bore 15011 and in a clearance fit with the first receiving bore 1131.

[0145] In particular, the second receiving bore 15011 is a through bore passing through the second tab 1501. Corresponding to the second receiving bore 15011, the first receiving bore 1131 passes at least partially through the first tab 113. The inner diameter of the first receiving bore 1131 is larger than that of the second receiving bore 15011, and the outer diameter of the first pivot shaft lies between that of the first receiving bore 1131 and the second receiving bore 15011. This means that the first pivot shaft 1902 is fixedly connected to the temple 15 and rotatably connected to the frame 11, allowing the frame 11 to be rotated around the first pivot shaft 1902 relative to the temple 15, thus folding or opening the spectacles.

[0146] Furthermore, it is provided that in one embodiment the first tab 113 and the third tab 1502 are coaxially provided with a third receiving bore 1132 and a fourth receiving bore 15021 respectively, wherein the third receiving bore 1132 and the fourth receiving bore 15021 are dimensioned such that the second rotating shaft 1903 can be inserted from the outside of the spectacle arm 15 through the fourth receiving bore 15021 into the third receiving bore 1132, and that the second rotating shaft 1903 is in an interference fit with the third receiving bore 1132 and in a clearance fit with the fourth receiving bore 15021, or that the second rotating shaft 1903 is in a clearance fit with the third receiving bore 1132 and in an interference fit with the fourth receiving bore 15021.

[0147] In the present embodiment, the third receiving bore 1132 and the fourth receiving bore 15021 are provided coaxially with the first receiving bore 1131 and the second receiving bore 15011, respectively. The third receiving bore 1132 extends through at least a portion of the first tab 113. In one application scenario, the first receiving bore 1131 and the third receiving bore 1132 are coaxial and continuous. As described in the embodiment above, it is particularly provided that the first tab 113 of the spectacle frame 11 is provided with a wiring channel connected to the first wiring opening 190213. The first receiving bore 1131 and the third receiving bore 1132 are each provided on two sides of the wiring channel in the first tab 113 and extend through the wiring channel. The fourth receiving bore 15021 extends through the third tab 1502.The outer diameter of the second rotating shaft 1903 lies between the inner diameter of the third receiving bore 1132 and that of the fourth receiving bore 15021, the inner diameter of the third receiving bore 1132 is larger than that of the fourth receiving bore 15021, or the inner diameter of the fourth receiving bore 15021 is larger than that of the third receiving bore 1132. This means that the second rotating shaft 1903 is either fixedly connected to the temple 15 and rotatably connected to the frame 11, or the second rotating shaft 1903 is fixedly connected to the frame 11 and rotatably connected to the temple 15. This allows the frame 11 to be rotated around the first rotating shaft 1902 relative to the temple 15, and thus folded or opened.

[0148] In one embodiment, the second rotating shaft 1903 can be designed as a solid shaft with a diameter smaller than the diameter of the first rotating shaft 1902. When worn, the second rotating shaft 1903 is located on the upper side of the temple 15 and the first rotating shaft 1902 on the lower side of the temple 15.

[0149] It should be noted that by providing the rotating shaft wiring channel 1901 inside the first rotating shaft 1902, the outer diameter of the first rotating shaft 1902 is large, which is detrimental to the aesthetic requirements for the user. Therefore, in the present embodiment, a second rotating shaft 1903 with a small outer diameter is also provided, so that when the user wears the glasses, the second rotating shaft 1903 is located on a more visible upper part, while the first rotating shaft 1902 is located on a less visible lower part. Since the outer diameter of the second rotating shaft 1903 is small, the overall aesthetic effect of the glasses can be improved to some extent.

[0150] Of course, in another embodiment, the first rotating shaft 1902 and the second rotating shaft 1903 can also be designed differently. For example, the second rotating shaft 1903 can also be designed as a hollow shaft, and the diameter of the second rotating shaft 1903 can also be larger than the diameter of the first rotating shaft 1902. Alternatively, in the worn state, the second rotating shaft 1903 is located on the underside of the temple 15 and the first rotating shaft 1902 on the upper side of the temple 15, although this is not defined here.

[0151] See further Fig. 14. Furthermore, a connection point between the end face 19022 of the first rotating shaft 1902, on which the first wiring opening 190213 is provided, and the inner wall surface 19023 of the first rotating shaft 1902, which defines the rotating shaft wiring channel 1901, is arc-shaped. It is easy to understand that during the rotation of the spectacle frame 11 relative to the temple 15 by the rotating shaft assembly 190, the connecting wire 17 at the first wiring opening 190213 is set in motion, since there is a rotatable connection between the first rotating shaft 1902 and the spectacle frame 11. In the present embodiment, the connection point between the above end face 19022 and the inner wall surface 19023 of the first rotating shaft 1902 is arc-shaped.This prevents the connecting wire 17 from being cut and damaged when it moves at the first wiring opening 190213 and comes into contact with the first rotating shaft 1902, because the connection point above is too sharp. This further protects the connecting wire 17.

[0152] In one application scenario, a connection point between the end face of the first rotating shaft 1902, where the second wiring opening 190214 is provided, and the inner wall surface 19023 of the first rotating shaft 1902, which defines the rotating shaft wiring channel 1901, is also formed in an arc shape. In this way, the connecting wire 17 can be further protected.

[0153] It should be noted that the above description of the rotating shaft arrangement and wiring of the glasses represents only detailed examples and should not be considered the only possible embodiment. For those skilled in the art, it is obvious, based on the understanding of the basic principle of the rotating shaft arrangement and wiring of the glasses, that various modifications and changes to the rotating shaft arrangement and wiring of the glasses can be made with regard to the methods and steps for its implementation, including its design and details, without deviating from this principle. These modifications and changes, however, still fall within the scope described above. For example, the secondary circuit board can further include a third solder pad and a third flexible circuit board. Such variants are within the scope of protection of the present application.

[0154] Fig. Figure 19 shows an exploded structural representation of the loudspeaker according to some embodiments of the present application, Fig. Figure 20 shows a partially cutaway representation of the loudspeaker according to some embodiments of the present application, and Fig. Figure 21 shows an enlarged view of part A from Fig. 20. As in Fig. As shown in Figures 19 to 21, in some embodiments the loudspeaker may comprise an assembly body, wherein a chamber 1911 is formed inside the assembly body. It should be noted that the assembly body is located in the temple of the spectacles 15 ( Fig. 7) can be located in the above embodiments. In some embodiments, at least two dual microphones can also be provided in the temple 15.

[0155] It should be noted that the auxiliary function module 104 can be located either in the core housing 108 or in the fastening mechanism 110, for example in the temple of the glasses 15 ( Fig. 7).

[0156] The assembly body can be a structure consisting of at least two components. It can also be a structure manufactured using one-piece molding technology, such as injection molding. The spatial shape of the assembly body can be a cuboid, square, ellipsoid, sphere, cone, or any other irregular shape, but this is not limited to those. The material of the assembly body can be plastic, silicone, rubber, glass, ceramic, alloy, stainless steel, etc., or a combination thereof.

[0157] In some embodiments, the assembly body can comprise a receiving body 1910 and a cover 1920. The chamber 1911 is formed as a hollow space within the receiving body 1920. The receiving body 1910 is provided with an opening 1912 connected to the chamber 1911. The cover 1920 covers the opening 1912 and seals the chamber 1911. The chamber 1911 can be a single, formed internal cavity if it is assembled from two or more components. Alternatively, it can also be an internal cavity formed during the one-piece molding of the assembly according to the shape of a mold. The chamber 1911 can be used to house several electronic elements and circuit structures of the loudspeaker. The assembly body can be used to seal the chamber 1911.Chamber 1911 can either be completely sealed by the assembly body or sealed jointly by the assembly body and other accessories on the assembly body.

[0158] The receiving body 1910 can be designed as at least one part of the loudspeaker. In the present embodiment, the receiving body 1910 can, in particular, be designed as a structure of the loudspeaker for receiving, for example, a circuit board, a battery 52, and electronic elements, etc., for example, as the whole or a part of an outer housing or the like of the loudspeaker.

[0159] Furthermore, the receiving body 1910 serves to receive the above-mentioned circuit board, battery, and electronic components, etc., by means of the chamber 1911 with the opening 1912. The opening 1912 is connected to the chamber and serves as an assembly and disassembly channel for the above-mentioned circuit board, battery, electronic components, etc. In particular, either one or more openings 1912 may be provided, although this is not defined here.

[0160] Furthermore, it is provided that the shape of the cover 1920 fits at least partially with the opening 1912 mentioned above, so that the cover 1920 covers the opening 1912 and thus seals the chamber 1911. The material of the cover 1920 may be different from, or at least partially the same as, the receiving body 1910.

[0161] In the present embodiment, the cover 1920 comprises a hard support 1921 and a soft cover layer 1922. The hard support 1921 serves for the mechanical connection with the receiving body 1910. The soft cover layer 1922 is injection-molded in one piece onto a surface of the hard support 1921 to provide a seal for the chamber 1911 after the connection of the hard support 1921 with the receiving body 1910.

[0162] In particular, the material of the hard support 1921 can be hard plastic. The material of the soft outer layer 1922 can be soft silicone, rubber, or the like. The shape of the side of the hard support 1921 facing the receiving body 1910 can fit the opening 1912, so that the hard support can be attached to the opening 1912 of the chamber 1911 by plugging, snapping, or the like, and is thus mechanically connected to the receiving body 1910. However, play is likely to develop at a connection point between the hard support 1921 and the receiving body 1910, which reduces the seal of the chamber 1911.Furthermore, it is provided that the soft cover layer 1922 is formed by one-piece injection molding on an outer surface of the hard support 1921 located further away from the receiving body 1910 and that it can further cover the connection point of the hard support 1921 with the receiving body 1910 in order to seal the chamber 1911.

[0163] In the exemplary embodiment above, the cover 1920 comprises the rigid support 1921 and the soft cover layer 1922, which is injection-molded in one piece onto the surface of the rigid support 1921. The rigid support 1921 is mechanically connected to the receiving body 1910. The soft cover layer 1922 further provides a seal for the chamber 1911 after the connection of the rigid support 1921 to the receiving body 1910, and the soft cover layer 1922 is advantageously positioned at the gap between the rigid support 1921 and the receiving body 1910 to increase the tightness of the electronic assembly and thus its watertightness. The rigid support 1921 and the soft cover layer 1922 are injection-molded in one piece, thus simplifying the assembly process of the electronic assembly.

[0164] In one embodiment, the hard support 1921 comprises an insert part 19211 and a cover part 19212, wherein the cover part 19212 covers the opening 1912, and wherein the insert part 19211 is arranged on one side of the cover part 19212 and extends along an inner wall of the chamber 1911 into the chamber 1911 in order to attach the cover part 19212 to the opening 1912.

[0165] In one application scenario, the insert 19211 cannot simply be inserted over the inner wall of the chamber 1911. For example, the interior of the chamber 1911 may also be provided with a plug-in component that matches the shape of the insert 19211 and the hard support 1921, so that the insert 19211 can be plugged into the plug-in component to secure it inside the chamber 1911. For example, the insert 19211 has a cylindrical shape, and the plug-in component can be designed as an annular ring that can enclose the cylindrical insert 19211, with the inner diameter of the annular plug-in component being appropriately smaller than the outer diameter of the cylindrical insert 19211, so that when inserted, the insert 19211 is in an interference fit with the plug-in component, thus ensuring a stable connection between the hard support 1921 and the chamber 1911.Of course, other insertion methods are also possible, as long as it is possible for the insertion part 19211 to be inserted into the interior of the chamber 1911 and secured to the chamber 1911.

[0166] In particular, the cover part 19212 can be arranged on one side of the insert part 19211 facing away from the chamber 1911 and covers the opening 1912 after the insert part 19211 has been inserted into the chamber 1911. The cover part 19212 can form a complete structure or it can also be further provided with some holes as required to fulfill a specific function.

[0167] See more Fig. 22. Fig. Figure 22 shows a sectional view of the assembled loudspeaker of the present application along the AA axis. Fig. 19. In one embodiment, the receiving body 1910 comprises an opening edge 1913 defining the opening 1912, wherein the cover part 19212 is pressed against an inner region 19131 of the opening edge 1913 located near the opening 1912, and wherein the soft cover layer 1922 covers an outer surface of the cover part 19212 located further away from the receiving body 1910 and is pressed against an outer surface 19132 of the opening edge 1913 located peripherally around the inner region 19131, so that a seal is formed at the opening edge 1913.

[0168] The inner area 19131 and the outer area 19132 of the opening edge 1913 belong to the opening edge 1913 and are not areas outside the opening edge 1913. The inner area 19131 of the opening edge 1913 is a region of the opening edge 1913 located close to the opening 1912, while the outer area 19132 of the opening edge 1913 is a region of the opening edge 1913 located further away from the opening 1912.

[0169] In the present embodiment, the cover part 19212 of the rigid support 1921 is pressed against the inner area 19131 of the opening edge 1913, which is located near the opening 1912, so that the cover part 19212 can initially provide a preliminary seal at the opening edge 1913. However, because the receiving body 1910 and the rigid support 1921 are made of a hard material, and the connection between the two and the further covering by the cover part 19212 cannot achieve a good sealing effect, a gap is prone to forming between an end where the cover part 19212 is pressed against the opening edge 1913 and is further away from the opening 1912, and the opening edge 1913. Furthermore, this gap forms a connection with the chamber 1911, thus reducing the seal.

[0170] Therefore, in the present embodiment, the soft cover layer 1922 is provided to cover an outer surface of the cover part 19212 located further away from the receiving body 1910 and is pressed further against the outer surface 19132 of the opening edge 1913, which is formed peripherally around the inner area 19131, so that the gap that arises between the cover part 19212 of the hard support 1921 and the opening edge 1913 can be further covered. Furthermore, because the soft cover layer 1922 is made of a soft material, the sealing effect of the loudspeaker can be further increased, thus improving the loudspeaker's water resistance.

[0171] See more Fig. 23. Fig. Figure 23 shows an enlarged structural representation of part B. Fig. 22. In one application scenario, it is provided that in a locked state of the cover 1920 the periphery of the cover part 19212 covers the inner area 19131 of the opening edge 1913 and is in contact with the inner area 19131 of the opening edge 1913. In contrast, the soft cover layer 1922 is provided on a side of the cover part 19212 that is further away from the receiving body 1910, so that the cover part 19212 located in the inner area 19131 of the opening edge 1913 is clamped between the inner area 19131 of the opening edge 1913 and the soft cover layer 1922, and the soft cover layer 1922 extends further in a direction of the cover part 19212 that is further away from the opening 1912 and in the direction towards the opening edge 1913 until it makes contact with the outer area 19132 of the opening edge 1913.This results in a contact end surface of the cover part 19212 being flush with the opening edge 1913 and a contact end surface of the soft cover layer 1922 being flush with the opening edge 1913. Furthermore, an "opening edge 1913-cover part 19212-soft cover layer 1922" structure is formed on the inner area 19131 of the opening edge 1913.

[0172] See more Fig. 24. In another application scenario, it shows Fig. Figure 24 shows a partially cutaway view of the loudspeaker according to an embodiment of the present application. In the present application scenario, the soft cover layer 1922, after extending to contact with the outer surface 19132 of the opening edge 1913, extends further along the area between the cover part 19212 and the opening edge 1913 to the inner surface 19131 of the opening edge 1913. Thus, it is assumed that an "opening edge 1913-soft cover layer 1922-cover part 19212-soft cover layer 1922" structure is formed between the inner surface 19131 of the opening edge 1913 and the cover part 19212, and at the inner surface 19131 of the opening edge 1913, where the cover part 19212 is pressed.In the present application scenario, the soft top layer 1922 is intended not only to cover the top part 19212 of the hard support 1921, but also to extend further between the hard support 1921 and the opening edge 1913 in order to further increase the seal between the chamber 1911 and the cover 1920 and to further improve the waterproof effect of the loudspeaker.

[0173] See further Fig. 19 to 24. In one embodiment, the loudspeaker further comprises a circuit arrangement 1930 arranged in the chamber 1911, wherein a switch 19311 is arranged on the circuit arrangement 1930.

[0174] In particular, the circuit arrangement 1930 can comprise a first printed circuit board 1931. The switch 19311 is arranged on a side of the first printed circuit board 1931 facing the outside of the opening 1912 of the chamber 1911. Either one or more switches 19311 can be provided. If several switches 19311 are provided, they can be spaced apart from one another on the first printed circuit board 1931. It should be noted that the first printed circuit board 1931 corresponds to the first secondary printed circuit board in the above embodiments.

[0175] Accordingly, a switch opening 19213 corresponding to the switch 19311 is provided on the hard carrier 1921, wherein the switch opening 19213 is further covered by the soft cover layer 1922, and wherein a pressure element 19221 is arranged at a position corresponding to the switch opening 19213. The pressure element 19221 extends through the switch opening 19213 towards the interior of the chamber 1911. When pressure is applied to the soft cover layer 1922 at the corresponding position, the pressure element 19221 is pressed against the switch 19311 on the circuit assembly 1930, thus triggering the circuit assembly 1930 to perform predetermined functions.

[0176] The contact element 19221 projects from the side of the soft cover layer 1922 facing the carrier 1921 towards the switch opening 19213 and the switch 19311. The shape of the contact element 19221 matches the switch opening 19213, so that when pressure is applied to the soft cover layer 1922 at the corresponding position, the contact element 19221 can reach the corresponding switch 19311 on the first circuit board 1931 through the switch opening 19213. Simultaneously, the length of the contact element 19221 towards the switch 19311 is dimensioned such that, when no pressure is applied to the soft cover layer 1922 at the corresponding position, the contact element is not pressed against the switch 19311, but can be pressed against the corresponding switch 19311 when pressure is applied.

[0177] In an application scenario, a position corresponding to the pressure part 19221 on the soft cover layer 1922 projects further towards a side facing away from the hard support 1921, forming a raised pressure part 19222, so that the user can be clearly informed about the position of the switch 19311 and the circuit arrangement 1930 for implementing respective functions is triggered by pressing on the corresponding pressure part 19222.

[0178] In some embodiments, the auxiliary function module 204 can serve to receive auxiliary signals and to perform an auxiliary function. The auxiliary function module 204 can be a module located outside the earphone core and serve to receive auxiliary signals in order to perform an auxiliary function. Furthermore, it is provided that the auxiliary function module 204 can perform one or more of the following functions: a visual function, a speech function, an auxiliary control function, and a switch control function. In the present application, the conversion of the audio signals into sound signals can be considered the main function of the loudspeaker, while functions other than the main function can be considered auxiliary functions of the loudspeaker.For example, the speaker's auxiliary functions may include receiving sound from the user and / or the environment through a microphone, controlling the playback of sound signals through a button, etc.

[0179] Furthermore, it is provided that the auxiliary function module can comprise at least a first auxiliary function module and a second auxiliary function module. The first auxiliary function module can be arranged on the primary circuit board 445. The second auxiliary function module can be arranged on the first secondary circuit board 442.

[0180] Furthermore, it is provided that the auxiliary function module can also include a third auxiliary function module. The third auxiliary function module is located on the second secondary circuit board.

[0181] In particular, the second auxiliary function module can be a first microphone element 19312 and the third auxiliary function module a second microphone element 19321. The first microphone element 19312 and the second microphone element 19321 can be MEMS (microelectromechanical system) microphones, which exhibit low operating current, relatively stable performance, and high speech quality.

[0182] It should be noted that the first microphone element 19312 and the second microphone element 19321 correspond to the microphones 432 in the above embodiments.

[0183] In some embodiments, the first microphone and the second microphone are distributed in a certain way in the loudspeaker, such that a main sound source (for example, the mouth of the person) is located in a direction of the second microphone element 19321 pointing towards the first microphone element 19312.

[0184] In particular, the first microphone element 19312 is arranged on a side of the first circuit board 1931 facing the cover 1920, while the second microphone element 19321 is arranged on a side of the second circuit board 132 facing the receiver body.

[0185] When the user wears the loudspeaker, the mouth can be considered the near-field sound source for the first microphone element 19312 and the second microphone element 19321 because the distance between the mouth (the main sound source) and the first and second microphone elements 19321 is less than the distance between any other sound source (e.g., a noise source) in the environment and the first and second microphone elements 19312. With respect to the near-field sound source, the intensities of the sounds received by the two microphone elements depend on their distances from the sound source. Because the first microphone element 19312 is located closer to the main sound source, it receives a stronger audio signal V. J1 Because the second microphone element 19321 is located at a greater distance from the main sound source, the second microphone element 19321 receives a weaker audio signal V.J2 That is, V J1 > V J2 applies.

[0186] Because the noise source in the environment is located at a greater distance from the first microphone element 19312 and the second microphone element 19321, it can be considered a far-field sound source for both. With respect to the far-field sound source, the strengths of the noise signals received by the two microphone elements are approximately equal, i.e., V Y1 ≈ V Y2 applies.

[0187] Therefore, the following applies to the total sound signal received by the first microphone element 19312: V1=VJ1+VY1

[0188] The following applies to the total sound signal received by the second microphone element: V2=VJ2+VY2

[0189] To eliminate noise from the received sound signal, the combined sound signal from the first microphone element 19312 and the combined sound signal from the second microphone element 19321 can be processed differentially. The differential processing can be performed as follows: V=V1−V2=(VJ1−VJ2)+(VY1−VY2)≈VJ1−VJ2

[0190] Furthermore, it is provided that, according to the difference result of the signal obtained using formula (3) and in conjunction with the distance of the first microphone element 19312 and the second microphone element 19321 to the main sound source, an audio signal actually received by the first microphone element 19312 and / or second microphone element 19321 and output by the main sound source, i.e. V J1 or V J2 , can be obtained.

[0191] To ensure the quality of the finally obtained audio signal, the difference result of the signal obtained in formula (3) should therefore be as large as possible, that is, V J1 >>V J2 This applies. In some embodiments of the present application, the effect can be achieved as follows: by arranging the mounting position of the first microphone element 19312 as close as possible to the main sound source (such as the person's mouth), by arranging the mounting position of the second microphone element 19321 as far away as possible from the main sound source (such as the person's mouth), by isolating the spaces between the two microphones, and by placing a sound barrier or the like between the two microphone elements. It should be noted that the above means enable an increase in the quality of the audio signal, and these means can be used either individually or in combination.

[0192] To position the first microphone element 19312 as close as possible to the main sound source (such as the person's mouth), some embodiments provide that the first circuit board 1931 and the first microphone element 19312 mounted on it can be arranged at an angle. To position the second microphone element 19321 as far away as possible from the main sound source (such as the person's mouth), some embodiments provide that the second circuit board 132 and the second microphone element 19321 mounted on it can be arranged at an angle to flexibly adjust the required mounting distance. It is also possible to arrange a sound guide channel and sound barrier element at each mounting area of ​​the microphone element. The specific mounting method can be further described with reference to Fig. 25 to 19 and their relevant descriptions will be taken.

[0193] It should be noted that the second circuit board 1932 corresponds to the second secondary circuit board in the above embodiments.

[0194] See more Fig. 25 and Fig. 26. In one embodiment, it is provided that Fig. 25 a sectional view of the assembled loudspeaker of the present application along axis BB from Fig. 19 shows, and that Fig. 26 a schematic structural representation of a first and a second printed circuit board, which have a different angle than in Fig. 25, as shown in an embodiment of the present application. The first printed circuit board 1931 comprises the first microphone element 19312. In particular, it is provided that the first printed circuit board 1931 is arranged facing the cover 1920, with the first microphone element 19312 being arranged on a side of the first printed circuit board 1931 facing the cover 1920. For example, in the embodiments above, the first microphone element 19312 can be spaced apart from the switch 19311 on the first printed circuit board 1931. In particular, the first microphone element 19312 is used to receive sound signals from the external environment of the loudspeaker and to convert the sound signals into electrical signals in order to analyze and process them.

[0195] Accordingly, the carrier 1921 can be provided with a first microphone opening 19214 corresponding to the first microphone element 19312, and the soft cover layer 1922 with a first sound-guiding opening 19223 corresponding to the first microphone opening 19214. The first sound-guiding opening 19223 can be arranged corresponding to the first microphone element 19312.

[0196] In particular, the first sound conduction opening 19223 is provided in the cover 1920, wherein one end of the first sound conduction opening 19223 is connected to the first microphone opening 19214 in the cover 1920 and the other end of the first sound conduction opening 19223 is directed towards the first microphone element 19312, so that the sound conduction distance can be shortened and the sound conduction effect increased.

[0197] In particular, it is provided that the first circuit board 1931 is parallel or inclined to the cover 1920, and that the first sound guide opening 19223 is perpendicular or inclined to the surface of the cover 1920.

[0198] In some embodiments, the depth direction of the opening 1912 relative to the underside of the receiving body 1910 can be either vertical or inclined. If the opening 1912 is vertical, the closed cover 1920 is horizontally oriented relative to the receiving body 1910. If the opening 1912 is inclined, the closed cover 1920 is inclined relative to the receiving body 1910. The inclination is directed towards the mouth of the human body, allowing the first sound-guiding opening 19223 to be more directly facing the person's mouth or face, thereby increasing the effectiveness of the microphone arrangement in receiving sound from a primary sound source.

[0199] Furthermore, it is provided that, in the case of the inclined opening 1912, an angle between a plane of the opening 1912 and a plane of the lateral direction of the receiving body lies in the range of 10° to 30°, so that the first sound-guiding opening 19223 is oriented further towards the mouth area of ​​the person. In the case of the inclined opening 1912, the angle between the plane of the opening 1912 and the plane of the lateral direction of the receiving body can be any angle within the aforementioned range, for example 10°, 15°, 20°, 23°, 27°, 30°, etc., although this is not specifically defined here.

[0200] In particular, the first sound-guiding opening 19223 extends through the soft cover layer 1922. If the opening 1912 is vertical and the first circuit board 1931 runs parallel to the cover 1920, the first sound-guiding opening 19223 is provided perpendicular to the cover 1920, that is, the first sound-guiding opening 19223 is vertical. If the opening 1912 is vertical and the first circuit board 1931 runs at an angle to the cover 1920, the first sound-guiding opening 19223 is provided at an angle to the cover 1920, that is, the first sound-guiding opening 19223 is inclined. If the opening 1912 is inclined and the first circuit board 1931 runs parallel to the cover 1920, the first sound-guiding opening 19223 is provided perpendicular to the cover 1920, that is, the first sound-guiding opening 19223 is inclined.If the opening 1912 is inclined and the first circuit board 1931 is inclined towards the cover 1920, the first sound-guiding opening 19223 can also be inclined towards the cover 1920, that is, the first sound-guiding opening 19223 can be either vertical or inclined.

[0201] Furthermore, it is provided that the angle between the first circuit board 1931 and a plane of the cover 1920 lies in the range of 5° to 20° when the first circuit board 1931 is inclined towards the cover 1920. In particular, the angle between the first circuit board 1931 and the plane of the cover 1920 can be any angle such as 5°, 8°, 10°, 15°, or 20° within this range when the first circuit board 1931 is inclined towards the cover 1920. This is not specifically defined.

[0202] In particular, the first sound guide opening 19223 corresponds to the first microphone opening 19214 on the support 1921 and in turn connects the first microphone element 19312 with the external environment of the loudspeaker, so that sound from the external environment of the loudspeaker can be received by the first microphone element 19312 via the first sound guide opening 19223 and the first microphone opening 19214.

[0203] To further increase the sound conduction effect, a central axis of the first sound conduction opening 19223 overlaps with a main axis of a sound receiving area 193121 of the first microphone element 19312. The sound receiving area 193121 of the first microphone element 19312 is a sound wave receiving area (for example, a diaphragm) on the first microphone element 19312. When the central axis of the first sound conduction opening 19223 overlaps with the main axis of the sound receiving area 193121 of the first microphone element 19312, the sound from the main sound source is captured by the first microphone opening 19214 and can then be guided directly through the first sound conduction opening 19223 to the sound receiving area 193121 of the first microphone element 19312, thereby further reducing the sound propagation distance.Thus, not only the loss and echo due to repeated propagation of the main sound source in the chamber, but also the transmission of the main sound source via the channel in the chamber to the area of ​​the second microphone element 19321 can be avoided, thus improving the sound effect.

[0204] In one embodiment, the cover 1920 is elongated, with the main axis of the first sound-guiding opening 19223 overlapping the main axis of the sound-receiving area 193121 of the first microphone element 19312 in the width direction of the cover 1920. The main axis of the sound-receiving area 193121 of the first microphone element 19312 is a main axis of the sound-receiving area 193121 of the first microphone element 19312 in the width direction of the cover 1920, as the axis n in Fig. 25. The main axis of the first sound guide opening 19223 is, for example, the axis m in Fig. 25, where axis n overlaps with axis m.

[0205] Furthermore, it is provided that the shape of the first sound-guiding opening 19223 can be any form, as long as sound can be introduced into the external environment of the loudspeaker. In one application scenario, the first sound-guiding opening 19223 is a small circular opening and is located in an area of ​​the cover 1920 corresponding to the first microphone opening 19214. The small first sound-guiding opening 19223 can reduce the connection of the first microphone element 19312 or the like in the loudspeaker with the external environment, thus increasing the isolation of the loudspeaker.

[0206] Furthermore, it is provided that the sound guide channel 192241 can be curved in order to direct the sound signals entering through the first sound guide opening 19223 to the first microphone element 19312.

[0207] In particular, one application scenario provides that the main axis of the first sound guide opening 19223 is located in the center of the cover 1920 in the width direction of the cover 1920.

[0208] Simultaneously, a first sound-blocking element 19224 is arranged at one of the first sound-guiding openings 19223 corresponding to the position of the soft cover layer 1922 of the cover 1920. The first sound-blocking element 19224 extends through the microphone opening 19214 into the interior of the chamber 1911 to limit sound transmission in the direction of transmission of the first microphone element 19312. Furthermore, the sound-guiding channel 192241 is defined. One end of the sound-guiding channel 192241 is connected to the first sound-guiding opening 19223 on the soft cover layer 1922. The first microphone element 19312 is inserted into the sound-guiding channel 192241 from the other end of the sound-guiding channel 192241.

[0209] Furthermore, if the loudspeaker includes the switch 19311 in the above embodiments, the switch opening 19213 and the first microphone opening 19214 can be spaced apart from each other in the hard carrier 1921.

[0210] Furthermore, it is provided that the distance between the switch opening 19213 and the first microphone opening 19214 may be in the range of 10 to 20 mm, in particular it may also be 10 mm, 15 mm, 20 mm or the like.

[0211] Accordingly, the first sound barrier element 19224 extends from the soft cover layer 1922 or from the periphery of the first sound guide opening 19223 through the first microphone opening 19214 to the interior of the chamber 1911 and to the periphery of the first microphone element 19312, so that the sound guide channel 192241 is formed from the first sound guide opening 19223 to the first microphone element 19312, so that the sound signals from the loudspeaker entering the sound guide opening can reach the first microphone element 19312 directly via the sound guide channel 192241.

[0212] In particular, the shape of the sound guide channel 192241 in a cross-sectional area perpendicular to its longitudinal direction can, of course, coincide with the shape of the first microphone opening 19214 or the first microphone element 19312, or, of course, not coincide. In one application scenario, the cross-sectional shapes of the first microphone opening 19214 and the first microphone element 19312 are rectangular in the direction perpendicular to the support 1921 and facing the chamber 1911. Furthermore, the dimension of the first microphone opening 19214 is slightly larger than the peripheral dimension of the sound guide channel 192241, and the inner dimension of the sound guide channel 192241 is also no smaller than the peripheral dimension of the first microphone element 19312, so that the sound guide channel 192241 can reach the first microphone element 19312 through the first sound guide opening 19223 and peripherally enclose the first microphone element 19312.

[0213] In the manner described above, the soft cover layer 1922 of the loudspeaker is provided with the first sound-guiding opening 19223 and the sound-guiding channel 192241, which extends from the periphery of the first sound-guiding opening 19223 through the first microphone opening 19214 to the first microphone element 19312 and peripherally surrounds the first microphone element 19312. By providing the sound-guiding channel 192241, the sound signals entering through the first sound-guiding opening 19223 can reach the first microphone element 19312 through the first sound-guiding opening 19223 and be received by the first microphone element 19312, thus reducing the emission of sound signals during propagation and increasing the efficiency of sound signal reception by the loudspeaker.

[0214] In one application scenario, the loudspeaker is further provided to include a waterproof mesh 194 located in the sound-guiding channel 192241. The waterproof mesh 194 is attached to the first microphone element 19312 on a side of the soft cover layer 1922 facing the microphone element and covers the first sound-guiding opening 19223.

[0215] In particular, in an accessible position in the sound-guiding channel 192241, the support 1921 is formed with a convex surface opposite its position, so that the waterproof mesh 194 is clamped between the first microphone element 19312 and the convex surface or can also be glued directly to the periphery of the first microphone element 19312. The specific arrangement is not defined here.

[0216] In the present embodiment, the waterproof mesh 194 can, in addition to providing waterproofing for the first microphone element 19312, also have functions such as sound transmission and the like, in order to avoid negatively affecting the sound reception effect of the sound reception area 193121 of the first microphone element 19312.

[0217] It should be noted that, due to certain requirements of the circuit arrangement 1930, the first microphone element 19312 can be arranged in a first position on the first circuit board 1931. When providing the first sound-guiding opening 19223, due to aesthetic, convenience, and similar requirements, the first sound-guiding opening 19223 is arranged in a second position on the cover 1920. In the present embodiment, the first and second positions cannot correspond to each other in the width direction of the cover 1920. This results in the main axis of the first sound-guiding opening 19223 and the main axis of the sound-receiving area 193121 of the first microphone element 193912 being spaced apart from each other in the width direction of the cover 1920.As a result, the sound entered through the first sound guide opening 19223 could not reach the sound receiving area 193121 of the first microphone element 19312 along a straight line.

[0218] In the present embodiment, the cover 1920 can be part of the outer housing of the loudspeaker. To meet the overall aesthetic requirements of the loudspeaker, the first sound-guiding opening 19223 can be located in the center along the width of the cover 1920, so that the first sound-guiding opening 19223 appears more symmetrical and meets people's visual requirements.

[0219] In the present application scenario, the corresponding sound conduction channel 192241 can be stepped in the cross-sectional area along the axis BB in Fig. 19 be designed so that the sound signals introduced through the first sound guide opening 19223 are propagated via the stepped sound guide channel 192241 to the first microphone element 19312 and are received by the first microphone element 19312.

[0220] Furthermore, it is planned that Fig. 27 a sectional view of the assembled loudspeaker of the present application along the CC axis Fig. 19 shows. See further Fig. 27. In one embodiment, the loudspeaker further comprises a light element 19313. In particular, the light element 19313 can be arranged on the first circuit board 1931 of the circuit arrangement 1930, so that it is contained in the chamber 1911. For example, in the above embodiments, the light element 19313, together with the switch 19311 and the first microphone element 19312, can be arranged in a specific sequence on the first circuit board 1931. It should be noted that the circuit arrangement 1930 can correspond to the control circuit in the above embodiments.

[0221] Accordingly, the hard substrate 1921 can be provided with a light emission opening 19215 corresponding to the light emission element 19313. The soft cover layer 1922 covers the light emission opening 19215, and the thickness of a region of the soft cover layer 1922 corresponding to the light emission opening 19215 is dimensioned such that the light radiation generated by the light emission element 19313 can pass through the soft cover layer 1922.

[0222] The light source 19313 can be a light-emitting diode or the like. It is possible to provide one or more light sources 19313. The number of light emission openings 19215 in the rigid carrier 1921 can correspond to the number of light sources 19313. If several light sources 19313 are provided, there will be correspondingly different light emission openings 19215, so that different signals can be transmitted by different light sources 19313.

[0223] In the present embodiment, it is provided that, by certain means, the soft covering layer 1922 can also allow the light radiation emitted by the luminous element 19313 to pass into the external environment of the loudspeaker even when the light exit opening 19215 is covered.

[0224] In one application scenario, it is specifically provided that the thickness of a total area or partial area of ​​the soft covering layer 1922 corresponding to the light emission aperture 19215 can be dimensioned such that it is smaller than the thickness of a region of the soft covering layer 1922 corresponding to the periphery of the light emission aperture 19215, so that the light radiation emitted by the luminaire element 19313 can pass through the light emission aperture 19215 and further through the soft covering layer 1922. Of course, other means are also used to enable the area of ​​the soft covering layer 1922 covering the light emission aperture 19215 to transmit light radiation, although these are not specifically defined here. For example, it is provided that the total area or partial area corresponding to the light emission aperture 19215...A section of the soft top layer 1922 is provided with a window and the window is covered by a transparent or translucent material (such as thin film, quartz or the like) so that the light radiation emitted by the luminaire element 19313 can pass through the light exit opening 19215 and further through the window.

[0225] In the above manner, the soft cover layer 1922 not only covers the light emission opening 19215 of the respective light source 19313, but it is also designed so that the light radiation emitted by the light source 19313 can pass through the soft cover layer 1922 into the external environment of the loudspeaker, so that the light source 19313 can be sealed by the soft cover layer 1922 to improve the enclosure and water resistance of the loudspeaker, without affecting the light function of the loudspeaker.

[0226] In one embodiment, in particular, the hard support 1921 is further provided at the periphery of the light exit aperture 19215 with a light-blocking element 19216 extending towards the interior of the chamber 1911. The light-blocking element 19216 limits the direction of transmission of the light radiation generated by the luminaire element 19313.

[0227] The shape of the light emission opening 19215 can be any shape that allows the light radiation emitted by the luminous element 19313 to pass through, such as a circle, square, triangle, etc. In the present embodiment, the shape of the light emission opening 19215 is circular.

[0228] Since there is a certain distance between the illuminating element 19313 and the light emission aperture 19215, the light radiation emitted by the illuminating element 19313 partially escapes before reaching the light emission aperture 19215 if no restriction is provided. As a result, the light radiation cannot be effectively propagated to the light emission aperture 19215, thus reducing the brightness of the light visible from the outside environment of the loudspeaker, which is detrimental to the user's signal reception. By providing the light blocking element 19216 in the present embodiment, the direction of transmission of the light radiation generated by the illuminating element 19313 can be limited in order to reduce light leakage and thus increase the brightness of the light radiation transmitted through the light emission aperture 19215.

[0229] In particular, the light-blocking element 19216 in the present embodiment can be formed partially or completely by the rigid support 1921. For example, the rigid support 1921 can extend along the periphery of the light-exit opening 19215 into the interior of the chamber 1911 and surround the illuminating element 19313, thus forming a light channel for the propagation of the light radiation. Through the light channel, the light radiation generated by the illuminating element 19313 can propagate directly to the light-exit opening 19215 in the direction of the channel's arrangement. Alternatively, the rigid support 1921 can also not form a light channel, but only limit the propagation of the light radiation in one or more directions. For example, the rigid support 1921 can extend into the interior of the chamber 1911 only from one side of the light-exit opening 19215, thus forming a light-blocking element 19216 that covers the illuminating element 19313 on one side.Alternatively, the propagation of the light radiation can also be further limited in conjunction with another component. For example, the rigid support 1921 can extend from one side of the light exit aperture 19215 into the interior of the chamber 1911, thus forming a light-blocking element 19216 that covers the illuminating element 19313 on one side. The light-blocking element 19216 further fits the inner wall of the chamber 1911 or another structure of the rigid support 1921 to limit the direction of transmission of the light radiation generated by the illuminating element 19313 in several directions.

[0230] In one application scenario, the light source 19313 is arranged adjacent to the first microphone element 19312 on the first circuit board 1931, and the corresponding light emission aperture 19215 and the first microphone aperture 19214 are spaced apart from each other on the rigid substrate 1921. As described in the exemplary embodiments above, a first sound barrier element 19224 is provided at the periphery of the first microphone element 19312. This barrier element is formed by the soft cover layer 1922 and defines a sound channel 192241. The first sound barrier element 19224 extends through the first microphone aperture 19214, so that the first microphone element 19312 is spaced apart from the light source 19313, and the first microphone aperture 19214 is spaced apart from the light emission aperture 19215.

[0231] In particular, in the present application scenario, it is provided that the light-blocking element 19216 formed by the hard carrier 1921 fits a side wall of the first sound-blocking element 19224 located near the luminaire element 19313, with the two together limiting the direction of transmission of the light radiation generated by the luminaire element 19313.

[0232] In another application scenario, the chamber 1911 is elongated in a cross-sectional area perpendicular to the direction of the opening 1912. Accordingly, the rigid support 1921 is also elongated and is inserted into the chamber 1911 from the opening 1912 via the insertion part 19211 to form a mechanical connection with the chamber 1911. Insertion parts 19211 are provided on two sides along the length of the rigid support 1921. Thus, the illuminating element 19313 is also provided with corresponding insertion parts 19211 of the rigid support 1921 on two sides along the length of the rigid support 1921 in order to limit the light radiation on two sides of the illuminating element 19313.Furthermore, in the present application scenario, the light-blocking element 19216 is arranged on a side of the luminaire 19313 perpendicular to the longitudinal direction of the rigid support 1921, and a side wall of the first sound-blocking element 19224 is arranged on the other side of the luminaire 19313 perpendicular to the longitudinal direction of the rigid support 1921. Both elements can be parallel plate bodies and, together with the insert parts 19211 on two sides of the luminaire 19313, they further limit the direction of transmission of the light radiation generated by the luminaire 19313.

[0233] In one embodiment, the circuit arrangement 1930 of the loudspeaker is provided to comprise the first circuit board 1931 in the above embodiments of the loudspeaker and furthermore the second circuit board 1932. See in particular Fig. 19, Fig. 22, Fig. 25 and Fig. 26.

[0234] It should be noted that the second circuit board 1932 corresponds to the second secondary circuit board in the above embodiments.

[0235] In particular, the second circuit board 1932 is arranged facing the receiving body 1910 and is arranged at an angle to the first circuit board 1931 in the chamber 1911. One side of the second circuit board 1932 facing the receiving body 1910 is provided with a second microphone element 19321.

[0236] The second microphone element 19321 is arranged facing a side wall of the receiver body 1910, thus creating ample space near the second microphone element 19321. This facilitates the integration of a corresponding functional element on the receiver body 1910. Furthermore, the second circuit board 1932 is arranged at an angle to the first circuit board 1931. The functional elements on the two circuit boards can be offset, and the distance between them can be reduced, further minimizing and compressing the internal space of the loudspeaker.

[0237] The cover 1920 or the side wall of the receiving body 1910 opposite the first sound guide opening 19223 is further provided with a second sound guide opening 1914.

[0238] The side wall of the receiving body 1910 is provided with a second sound-guiding opening 1914, the second sound-guiding opening 1914 being located far from the first sound-guiding opening 19223. In some embodiments, the opening 1912 of the receiving body 1910 is an inclined opening, with the cover 1920 being inclined towards the receiving body 1910. The side wall of the receiving body 1910 opposite the first sound-guiding opening 19223 is one side of the chamber 1911. The second sound-guiding opening 1914 is provided on the side of the receiving body 1910. Furthermore, it is provided that the second sound-guiding opening 1914 is provided on one side of the receiving body 1910 and that the distance from the top of the receiving body 1910 is in the range of 3 to 6 mm. In particular, it can be 3 mm, 4 mm, 5 mm, 6 mm, etc.

[0239] In some embodiments, the cover 1920 is arranged horizontally with respect to the receiving body 1910 when the depth direction of the opening 1912 of the receiving body 1910 is vertical with respect to the underside of the receiving body. The side wall of the receiving body 1910 opposite the first sound-guiding opening 19223 is the top of the chamber 1911. The sound-guiding opening 1914 is provided on the top of the receiving body 1910. Furthermore, it is provided that the second sound-guiding opening 1914 can be provided in a central position on the top of the receiving body 1910.

[0240] In the above manner, the second sound guide opening 1914 can be located far from the main sound source in order to reduce the sound from the main sound source received through the second sound guide opening 1914, to increase the proportion of ambient noise received through the second sound guide opening 1914, and to improve the noise suppression effect.

[0241] As described in the above embodiments of the loudspeaker of the present application, the cover 1920 is provided with a first sound guide opening 19223, which corresponds to the first microphone element 19312 and the first microphone opening 19214, wherein the first microphone element 19312 is used to receive the sound input through the first sound guide opening 19223 and the second microphone element 19321 is used to receive the sound input through the second sound guide opening 1914.

[0242] Furthermore, it is provided that the central axis of the second sound guide opening 1914 overlaps with the main axis of the sound reception area of ​​the second microphone element 19321.

[0243] If the central axis of the second sound guide opening 1914 overlaps with the main axis of the sound receiving area of ​​the second microphone element 19321, the noise can be directed through the second sound guide opening 1914 directly to the sound receiving area of ​​the second microphone element 19321, thus reducing the propagation of noise within the chamber 1911. Simultaneously, the noise can be directed through the first sound guide opening 19223 directly to the sound receiving area 193121 of the first microphone element 19312. The noise received by the first microphone element 19312 and the second microphone element 19321 is nearly identical, which is advantageous for noise reduction during post-processing and thus improves the quality of the main sound source.

[0244] In some embodiments, the central axis of the second sound guide opening 1914 and the central axis of the first sound guide opening 19223 overlap or are parallel to each other.

[0245] The second sound guide opening 1914 and the first sound guide opening 19223 have the same central axis direction. That is, their central axes overlap or are parallel. Furthermore, one sound inlet of the second sound guide opening 1914 and one sound inlet of the first sound guide opening 19223 are oriented in opposite directions to reduce the main sound source received by the second sound guide opening 1914. This is advantageous for noise reduction during post-processing and thus improves the quality of the main sound source.

[0246] In some embodiments, the main axis of the sound reception area of ​​the second microphone element 19321 and the main axis of the sound reception area 193121 of the first microphone element 19312 overlap or are parallel to each other. The sound reception area of ​​the second microphone element 19321 receives the sound signals passing through the second sound guide opening 1914, and the sound reception area 193121 of the first microphone element 19312 receives the sound signals passing through the first sound guide opening 19223. Since the signals from the main sound source passing through the second sound guide opening 1914 are weak, the signals from the main sound source received by the sound reception area of ​​the second microphone element 19321 are also weak, which is advantageous for improving the quality of the audio signals.

[0247] In some embodiments, the first circuit board 1931 can be arranged parallel to the opening plane of the opening 1912 and in the vicinity of the opening 1912. Alternatively, the first circuit board 1931 can also be arranged at an angle to the opening plane of the opening 1912 and in the vicinity of the opening 1912. Furthermore, it is provided that the switch 19311, the light element 19313, and other elements described above can also be arranged on the first circuit board 1931. The switch 19311, the light element 19313, and the first microphone element 19312, etc., can be arranged on the first circuit board 1931 in a specific configuration. Accordingly, the switch opening 19213, the light emission opening 19215, and the first microphone opening 19214, etc., are spaced apart from one another on the cover 1920 to allow signal transmission to the external environment of the loudspeaker via the respective openings.

[0248] Furthermore, it is provided that the first microphone opening 19214 can be arranged centrally in the middle of the cover 1920, with the switch opening 19213 and the light emission opening 19215 each being arranged on two sides of the first microphone opening 19214 along the longitudinal direction of the cover 1920. The distance between the switch opening 19213 or the light emission opening 19215 and the first microphone opening 19214 can be in the range of 5 to 10 mm, in particular 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm, etc. The distances of the switch opening 19213 and the light emission opening 19215 to the first microphone opening 19214 can be the same or different.

[0249] In some embodiments, the receiving body 1910 extends from the opening 1912 in a direction perpendicular to the plane of the opening to form the chamber 1911 with a specific width. The second circuit board 1932 can run parallel to the width direction of the chamber 1911 and be arranged perpendicular to the plane of the opening. Alternatively, the second circuit board 1932 can also run at an angle to the width direction of the chamber 1911 and be arranged at an angle to the plane of the opening 1912. The second circuit board 1932 can be arranged at an angle relative to the first circuit board 1931 within the chamber 1911. Furthermore, a main control chip and an antenna, etc., can be arranged on the second circuit board 1932.

[0250] In some embodiments, the second circuit board 1932 is inclined to the width direction of the chamber 1911 and is arranged at an angle to the plane of the opening 1912. The angle between the second circuit board 1932 and the width direction of the chamber 1911 can be in the range of 5° to 20°. In particular, the angle between the second circuit board 1932 and the width direction of the chamber 1911 can be any angle within the aforementioned range, for example 5°, 10°, 15° or 20°, etc., without this being specifically defined here.

[0251] In an application scenario where a user uses the loudspeaker, the main axis of the sound reception area of ​​the second microphone element 19321 can overlap with the main axis of the sound reception area 193121 of the first microphone element 19312, with the first microphone element 19312, the second microphone element 19321 and the user's mouth lying on a straight line.

[0252] In the present embodiment, the first microphone element 19312 and the second microphone element 19321 are arranged on each of the two circuit boards. The two microphone elements receive sound signals via the first sound guide aperture 19223 and the second sound guide aperture 1914, respectively. One of the microphone elements can be used to capture main sound components, such as the human voice, while the other microphone element can have background noise detection capabilities to record ambient sounds. The two microphone elements work together to analyze and process the received sound signals, thereby enabling noise reduction and other functions, thus improving the quality of the sound signal processing.

[0253] As in Fig. 25 and Fig. As shown in 26, it is still planned that Fig. 26 a schematic structural representation of the assembled loudspeaker, which has a different angle than in Fig. As shown in an embodiment of the present application, the first printed circuit board 1931 and the second printed circuit board 1932 are arranged at an angle to each other in the same chamber 1911. This allows for more flexible mounting of the two printed circuit boards, as the angle between them can be adjusted according to the size and position of the electronic components mounted on them. This improves the space utilization of the loudspeaker, thus reducing the loudspeaker's installation space in a further application, which in turn contributes to the realization of a lighter and thinner loudspeaker.

[0254] Furthermore, it is provided that the angle between the first circuit board 1931 and the second circuit board 1932 lies in the range of 50° to 150°. In particular, the angle between the first circuit board 1931 and the second circuit board 1932 can be any angle within this range, for example 70°, 80°, 90°, 100° or 110°, etc.

[0255] In one application scenario, in particular, it is provided that the opening 1912 and the cover 1920 are elongated, the shape of the first circuit board 1931 corresponding to the shape of the opening 1912, and the width d1 of the first circuit board 1931 not exceeding the dimension of the opening plane in the width direction of the opening 1912, so that the first circuit board 1931 (parallel or inclined to the opening plane) can be accommodated in the chamber 1911 in a position close to the opening 1912; i.e., the first circuit board 1931 is also elongated. Accordingly, the switch 19311, the light element 19313, and the first microphone element 19312 can be spaced apart from one another on the first circuit board 1931 in the longitudinal direction of the first circuit board 1931, i.e., in the longitudinal direction of the cover 1920.

[0256] In some embodiments, the second microphone element 19321 is a bone conduction microphone that protrudes from the receiver 1910 through the second sound conduction opening 1914. The bone conduction microphone is attached to a side wall of the receiver 1910. This side wall corresponds to the side wall that rests against the user's body when the loudspeaker is carried, so that the bone conduction microphone can better receive vibration signals from the main sound source. When the user carries the loudspeaker for speech input, the second microphone element 19321 primarily detects the vibration signals from the main sound source. These vibration signals are then compared with the sound signals (including audio signals and noise) detected by the first microphone element 19312 (via air conduction).In some embodiments, the sound signals captured by the first microphone element 19312 can be optimized based on the above comparison result in order to obtain high-quality audio signals.

[0257] In some embodiments, the second sound-guiding opening 1914 is provided on the assembly body, which extends through a side wall of the chamber 1911, with a second sound-blocking element 1915 being arranged at a position corresponding to the second sound-guiding opening 1914. The second sound-blocking element 1915 extends through the second sound-guiding opening 1914 into the interior of the chamber 1911 in order to limit the sound transmission in the transmission direction of the second microphone element 19321.

[0258] In particular, in the present embodiment, it is provided that the second sound guide opening 1914 corresponding to the second microphone element 19321 is arranged on the assembly body and passes through the chamber 1911 in order to connect the second microphone element 19321 with the outside environment, so that the second microphone element 19321 can receive sound signals from the outside environment.

[0259] The second sound-blocking element 1915 can be made of a hard or a soft material. For example, the second sound-blocking element 1915 can be formed by the receiving body 1910 extending into the interior of the chamber 1911 along the periphery of the second sound-guiding opening 1914 on an inner surface of the chamber 1911. In the present embodiment, the second sound-blocking element 1915 can be formed by a soft rubber element injection-molded in one piece with the receiving body 1910 extending into the interior of the chamber 1911 along the periphery of the second sound-guiding opening 1914 on an inner surface of the chamber 1911.In one application scenario, the second sound barrier element 1915 can extend along the entire circumference of the second sound guide opening 1914 into the interior of the chamber 1911, reaching as far as the second microphone element 19321 and thus surrounding the sound receiving area of ​​the second microphone element 19321 to form a channel connecting the second sound guide opening 1914 with the second microphone element 19321. This allows sound signals from the external environment entering the second sound guide opening 1914 to pass directly through this channel and be received by the sound receiving area of ​​the second microphone element 19321. In another application scenario, the second sound barrier element 1915 does not need to completely surround the entire circumference of the second sound guide opening 1914.Instead, it can extend along one, two, or more sides of the second sound guide opening 1914 into the interior of the chamber 1911 and reach as far as the second microphone element 19321. In this way, the sound entering through the second sound guide opening 1914 is guided so that it is propagated to the second microphone element 19321 and received by its sound reception area.

[0260] It should be noted that the above description of the loudspeaker's dual-microphone module presents only detailed examples and should not be considered the only possible design. For experts in this field, it is obvious, after understanding the basic principle of the loudspeaker's dual-microphone module, that various modifications and changes to the loudspeaker's dual-microphone module can be made with regard to the methods and steps for its implementation, including its design and details, without deviating from this principle. These modifications and changes, however, still fall within the scope described above.For example, the dual-microphone arrangement can further comprise an audio signal processing arrangement that can compare the vibration signals of the main sound source, primarily detected by the second microphone element 19321, with the sound signals (including audio signals and noise) detected by the first microphone element 19312 (via air transmission). Furthermore, the sound signals detected by the first microphone element 19312 can be optimized based on the above comparison result to obtain high-quality audio signals. Such variants are within the scope of protection of the present application.

[0261] See Fig. 19, Fig. 20 and Fig. 21. In some embodiments, an electronic arrangement (also referred to as a circuit housing or assembly body) may comprise a receiving body 1910 and a cover 1920. The receiving body 1910 has a chamber 1911 which has at least one opening 1912, the cover 1920 covering the opening 1912 of the chamber 1911 to seal the chamber 1911. The electronic arrangement in this embodiment corresponds to the assembly body of the preceding embodiment.

[0262] In the present application, the electronic arrangement can be used in an electronic device, wherein the electronic device can be any electronic device whose internal structure needs to be sealed. Examples include earphones, MP3 players, hearing aids, mobile phones, tablets, or eyeglasses equipped with circuit arrangements and electronic components, etc., although this is not specifically defined here. In some embodiments, the electronic arrangement can be mounted on the temple 15 of the eyeglasses according to Fig. 7. In some embodiments, the electronic arrangement can also be referred to as a circuit housing.

[0263] In some embodiments, the receiving body 1910 can represent at least part of an electronic device, for example a loudspeaker.

[0264] In some embodiments, the circuit arrangement corresponds to that described in Fig. 2 control circuits shown.

[0265] Fig. 28 shows a sectional view of the assembled electronic arrangement of the present application along axis AA. Fig. 19. As in Fig. As shown in Figure 28, in some embodiments the receiving body 1910 comprises an opening edge 1913 defining the opening 1912, wherein the cover part 19212 is pressed against an inner area 19131 of the opening edge 1913 located near the opening 1912, and wherein the cover layer 1922 covers an outer surface of the cover part 19212 located further away from the receiving body 1910 and is pressed against an outer surface 19132 of the opening edge 1913, which is located peripherally around the inner area 19131, so that a seal is formed at the opening edge 1913.

[0266] Fig. Figure 29 shows a sectional view of the assembled electronic arrangement of the present application along axis BB. Fig. 19. As in Fig. As shown in Figure 29, the electronic arrangement can include a first microphone element 19312. In some embodiments, the first microphone element 19312 can also be arranged on a first printed circuit board 1931 of a circuit arrangement 1930, so that it is contained in a chamber 1911. For example, in the embodiments above, the first microphone element 19312 can be spaced apart from the switch 19311 on the first printed circuit board 1931. The first microphone element 19312 can be used to receive sound signals from the external environment of the electronic arrangement and to convert the sound signals into electrical signals for analysis and processing.

[0267] In some embodiments, a microphone opening 19214 corresponding to the first microphone element 19312 is provided on a carrier 1921, a first sound-guiding opening 19223 corresponding to the microphone opening 19214 is provided on a cover layer 1922, and a first sound-blocking element 19224 is provided at a position of the cover layer corresponding to the microphone opening 19214, wherein the first sound-blocking element 19224 extends through the microphone opening 19214 into the interior of the chamber 1911 and defines a sound-guiding channel 192241.

[0268] In some embodiments, the first sound-guiding opening 19223 extends through the cover layer 1922 and corresponds to the position of the first microphone element 19312. The first sound-guiding opening 19223 corresponds to the microphone opening 19214 on the carrier 1921 and in turn connects the first microphone element 19312 with the external environment of the electronic arrangement, so that sound from the external environment of the electronic arrangement can be received by the first microphone element 19312 via the first sound-guiding opening 19223 and the microphone opening 19214.

[0269] It should be noted that the above description of the glasses only provides detailed examples and should not be considered the only possible embodiment. For those skilled in the art, it is obvious, based on the understanding of the basic principle of the glasses, that various modifications and changes to the glasses can be made with regard to the methods and steps for their construction, as well as their design and details, without deviating from this principle. These modifications and changes, however, still fall within the scope described above. For example, either one or more openings 1912 may be provided, although this is not defined here. Furthermore, in some embodiments, either one or more switches 19311 may be provided. If several switches 19311 are provided, they may be spaced apart from one another on the first circuit board 1931.Such variants are within the scope of protection of the present application.

[0270] Fig. Figure 2 shows a structural section of an embodiment of a loudspeaker arrangement of the present application, Fig. Figure 3 shows an exploded structural section of an embodiment of the loudspeaker arrangement of the present application, and Fig. Figure 30 shows a partially cutaway, structural representation of an embodiment of the loudspeaker arrangement of the present application.

[0271] See Fig. 2 and Fig. 3. In some embodiments, an auxiliary function module may include microphones 432, wherein the number of microphones 432 is two, namely a first microphone 432a and a second microphone 432b. The first microphone 432a and the second microphone 432b may be MEMS (microelectromechanical system) microphones 432, which exhibit low operating current, relatively stable performance, and high speech quality. The two microphones 432 may be arranged in different positions on a flexible circuit board 44, according to actual requirements.

[0272] In some embodiments, the soft circuit board 44 can be arranged according to the one described in Fig. 1 shown soft circuit board 106 in the loudspeaker made of Fig. The flexible printed circuit board 44 can be arranged as follows: The flexible printed circuit board 44 can comprise a primary printed circuit board 441, as well as a secondary printed circuit board 442 and a secondary printed circuit board 443, which are connected to the primary printed circuit board 441. The secondary printed circuit board 442 and the primary printed circuit board 441 extend in the same direction. The first microphone 432a is mounted at an end of the secondary printed circuit board 442 that is farther from the primary printed circuit board 441. The secondary printed circuit board 443 extends perpendicular to the primary printed circuit board 441. The second microphone 432b is mounted at an end of the secondary printed circuit board 443 that is farther from the primary printed circuit board 441. Several solder pads 45 are arranged at an end of the primary printed circuit board 441 that is farther from the secondary printed circuit board 442 and the secondary printed circuit board 443.

[0273] In some embodiments, a core housing 41 comprises a circumferential wall 411 and a bottom wall 412 connected to an end face of the circumferential wall 411, thus forming a receiving chamber with an open end. An earphone core 102 is placed into the receiving chamber through the open end. The first microphone 432a is attached to the bottom wall 412, and the second microphone 432b is attached to the circumferential wall 411.

[0274] In some embodiments, the secondary circuit board 442 and / or the secondary circuit board 443 can be appropriately bent to adapt to the positions of the sound inlet openings corresponding to the microphones 432 in the core housing 41. In particular, the flexible circuit board 44 can be arranged in the core housing 41 such that the primary circuit board 441 runs parallel to the bottom wall 412. This allows the first microphone 432a to correspond to the bottom wall 412 without bending the primary circuit board 441. However, because the second microphone 432b is attached to the circumferential wall 411 of the core housing 41, the second primary circuit board 441 must be bent.In particular, the secondary circuit board 443 can be bent at the end furthest from the primary circuit board 441, so that the plate surface of the secondary circuit board 443 is perpendicular to the plate surfaces of the primary circuit board 441 and the secondary circuit board 442, and that, in turn, the second microphone 432b is attached to the circumferential wall 411 of the core housing 41 in a direction pointing away from the primary circuit board 441 and the secondary circuit board 442.

[0275] In some embodiments, a solder pad 45, a solder pad 46, the first microphone 432a and the second microphone 432b can be arranged on the same side of the soft circuit board 44 and the solder pad 46 is located adjacent to the second microphone 432b.

[0276] In some embodiments, the solder pad 46 can be arranged, in particular, at the end of the secondary circuit board 443 furthest from the primary circuit board 441, and it is aligned in the same direction as the second microphone 432b and spaced apart from it, so that when the secondary circuit board 443 is bent, it is perpendicular to the orientation of the solder pad 45. It should be noted that the surface of the secondary circuit board 443 may not be perpendicular to the surface of the primary circuit board 441 after bending, depending on the arrangement of the circumferential wall 411 and the bottom wall 412.

[0277] In some embodiments, a rigid support plate 4a for supporting the solder pad 45 and a rigid support plate 4b for the microphone are provided on another side of the soft circuit board 44. The rigid support plate 4b for the microphone comprises a rigid support plate 4b1 for supporting the first microphone 432a and a rigid support plate 4b2 for jointly supporting the solder pad 46 and the second microphone 432b.

[0278] In some embodiments, the rigid support plates 4a, 4b1, and 4b2 primarily serve to support the respective solder pads and microphones 432, and therefore must possess a certain degree of rigidity. The materials used for the three plates can be either the same or different. These materials can be, in particular, polyimide (polyimide film, PI) or other materials capable of providing the necessary support strength, such as polycarbonate, polyvinyl chloride, or the like. Furthermore, the thicknesses of the three rigid support plates can be adjusted according to their own inherent rigidity as well as according to the specific rigidity requirements of the solder pad 45, solder pad 46, the first microphone 432a, and the second microphone 432b, although this is not explicitly defined here.

[0279] The first microphone 432a and the second microphone 432b can each correspond to two microphone arrangements 4c. In some embodiments, the two microphone arrangements 4c have the same structure. The core housing 41 is provided with a sound inlet opening 413. Furthermore, the loudspeaker arrangement on the core housing 41 is provided with an annular barrier 414, which is integrally formed on the inner surface of the core housing 41. The annular barrier is formed peripherally at the sound inlet opening 413 and in turn defines a receiving chamber 415 connected to the sound inlet opening 413.

[0280] See Fig. 2, Fig. 3 and Fig. 30. In some embodiments, the microphone arrangement 4c further comprises a waterproof diaphragm arrangement 4c1.

[0281] The waterproof membrane assembly 4c1 is arranged in the receiving chamber 415 and covers the sound inlet opening 413. The rigid support plate 4b for the microphone is arranged in the receiving chamber 415 and is located on a side of the waterproof membrane assembly 4c1 further away from the sound inlet opening 413, in order to press the waterproof membrane assembly 4c1 against the inner surface of the core housing 41. In some embodiments, a sound inlet opening 4b3 corresponding to the sound inlet opening 413 is provided on the rigid support plate 4b for the microphone. In some embodiments, the microphones 432 are arranged on a side of the rigid support plate 4b for the microphone further away from the waterproof membrane assembly 4c1 and cover the sound inlet opening 4b3.

[0282] The waterproof membrane arrangement 4c1 has a waterproof and sound-permeable function and lies close to the inner surface of the core housing 41 to prevent liquid from outside the core housing 41 from entering the interior of the core housing 41 through the sound inlet opening 413 and impairing the performance of the microphones 432.

[0283] The axial directions of the sound inlet opening 4b3 and the sound inlet opening 413 can either coincide with each other or intersect at a specific angle according to the actual needs of the microphones 432.

[0284] The rigid support plate 4b for the microphone is arranged between the waterproof membrane assembly 4c1 and the microphones 432. Its purpose is twofold: firstly, to press the waterproof membrane assembly 4c1 into place so that it fits snugly against the inner surface of the core housing 41; and secondly, to provide support for the microphones 432.

[0285] In some embodiments, the material of the rigid support plate 4b for the microphone can be polyimide (polyimide film, PI) or another material that can provide sufficient strength for support, such as polycarbonate, polyvinyl chloride, or the like. Furthermore, the thickness of the rigid support plate 4b for the microphone can be adjusted according to the strength of the rigid support plate 4b for the microphone and the strength actually required for the microphones 432, although this is not specifically defined here.

[0286] Fig. Figure 31 shows an enlarged section of part C from Fig. 30. As in Fig. As shown in Figure 31, in some embodiments the waterproof membrane assembly 4c1 can comprise a waterproof membrane body 4c11 and an annular adhesive pad 4c12. The annular adhesive pad 4c12 is arranged on one side of the waterproof membrane body 4c11 facing the rigid support plate 4b for the microphone and, in turn, peripherally at the sound inlet opening 413 and the sound inlet opening 4b3.

[0287] The rigid support plate 4b for the microphone is pressed against the ring-shaped adhesive base 4c12, so that the waterproof membrane assembly 4c1 and the rigid support plate 4b for the microphone are bonded and fixed together.

[0288] In some embodiments, the annular adhesive pad 4c12 is designed such that a sealed chamber is formed between the waterproof membrane body 4c11 and the rigid support plate, which communicates with the microphones 432 exclusively via the sound inlet opening 4b3. That is, the connection between the waterproof membrane assembly 4c1 and the rigid support plate 4b for the microphone is seamless, so that the peripheral space around the annular adhesive pad 4c12, located between the waterproof membrane body 4c11 and the rigid support plate 4b for the microphone, is isolated from the sound inlet opening 4b3.

[0289] In some embodiments, the waterproof membrane body 4c11 can be, in particular, a waterproof and sound-permeable membrane corresponding to the eardrum of the human ear. When an external sound enters through the sound inlet opening 413, the waterproof membrane body 4c11 vibrates, thereby changing the air pressure in the sealed chamber and consequently generating sound in the microphones 432.

[0290] Furthermore, it is provided that the waterproof membrane body 4c11 causes a change in air pressure in the sealed chamber when vibrating. The air pressure must be controlled within a suitable range, as excessively high or low air pressure impairs the sound quality. In the present embodiment, the distance between the waterproof membrane body 4c11 and the rigid support plate can be 0.1 to 0.2 mm, in particular 0.1 mm, 0.15 mm, or 0.2 mm, etc., so that the air pressure changes caused by the vibration of the waterproof membrane body 4c11 in the sealed chamber are kept within a suitable range, thereby improving the sound quality.

[0291] In some embodiments, the waterproof membrane arrangement 4c1 further comprises an annular adhesive pad 4c13, which is arranged on a side of the waterproof membrane body 4c11 facing the inner surface of the core housing 41 and is stacked with the annular adhesive pad 4c12.

[0292] In this way, the waterproof membrane assembly 4c1 can lie close to the inner surface of the core housing 41, which is located peripherally around the sound inlet opening 413, so that the loss of the sound entering through the sound inlet opening 413 is reduced and the conversion rate of the sound into the vibration of the waterproof membrane body 4c11 is improved.

[0293] In some embodiments, the ring-shaped adhesive base 4c12 and the ring-shaped adhesive base 4c13 may each be double-sided adhesive or sealant, etc.

[0294] In some embodiments, a sealing adhesive can also be applied peripherally to the annular barrier wall 414 and the microphones 432 to further increase the tightness and thus improve the sound conversion rate and the sound quality.

[0295] In some embodiments, the soft circuit board 44 can be arranged between the rigid support plate and the microphones 432, and it is provided with a sound inlet opening 444 at a position corresponding to the sound inlet opening 4b3 of the rigid support plate 4b for the microphone, so that the vibration of the waterproof membrane body 4c11 caused by external sound passes through the sound inlet opening 444 and subsequently affects the microphones 432.

[0296] See Fig. 3. In some embodiments, the flexible circuit board 44 extends further in a direction away from the microphones 432 in order to connect with other functional elements or lines and thus fulfill their respective functions. Accordingly, the rigid support plate 4b for the microphone also extends with the flexible circuit board in a direction away from the microphones 432 over a distance.

[0297] Accordingly, the annular barrier wall 414 is provided with a notch that fits the shape of the flexible circuit board to allow the flexible circuit board to extend beyond the receiving space 415. Furthermore, a sealant can be applied to the notch to further increase the seal.

[0298] It should be noted that the above description of the microphone's waterproofing provides only detailed examples and should not be considered the only possible embodiment. For those skilled in the art, it is obvious, based on the understanding of the basic principle of microphone waterproofing, that various modifications and changes to the microphone's waterproofing can be made with regard to the methods and steps for its implementation, as well as its design and details, without deviating from this principle. These modifications and changes, however, still fall within the scope described above. For example, one or more sound inlet openings 413 may be provided. Such variants are within the scope of protection of this application.

[0299] Fig. Figure 32 shows a schematic structural section of the core housing of the loudspeaker arrangement according to some embodiments of the present application, Fig. Figure 33 shows an enlarged section of part D from Fig. 32, and Fig. Figure 34 shows a partially cutaway view of the core housing of the loudspeaker arrangement according to some embodiments of the present application.

[0300] See Fig. 32, Fig. 33 and Fig. 34. The core case can be a main case 2825 (i.e., the core case 108 in Fig. 1) and a partition plate arrangement 2826, wherein the partition plate arrangement 2826 is located inside the main housing 2825 and is connected to the main housing 2825, such that an interior space 2827 of the main housing 2825 is divided into a first receiving space 271 and a second receiving space 272, which is located near a plug-in opening 2822. In some embodiments, the main housing 2825 comprises a circumferential wall 251 and a bottom wall 252 connected to an end face of the circumferential wall 251, wherein the circumferential wall 251 and the bottom wall 252 together enclose an interior space 2827 of a main housing 2825.

[0301] In some embodiments, the partition plate arrangement 2826 is located on a side of the main housing 2825 near the connector opening 2822 and comprises a side partition plate 261 and a bottom partition plate 262. The side partition plate 261 can be arranged in a direction perpendicular to the bottom wall 252, and two ends of the side partition plate 261 are connected to the circumferential wall 251 to separate the interior 2827 of the main housing 2825.The lower partition plate 262 can be arranged parallel or approximately parallel to the bottom wall 252 and spaced apart from it, and is furthermore connected to the perimeter wall 251 and the side partition plate 261, so that the interior space 2827 formed by the main housing 2825 is divided into two parts: the first receiving space 271, which is enclosed by the side partition plate 261, the lower partition plate 262, a portion of the perimeter wall 251 located further away from the connector opening 2822, and the bottom wall 252; and the second receiving space 272, which is enclosed by the lower partition plate 262, the side partition plate 261, and a portion of the perimeter wall 251 located near the connector opening 2822. The second receiving space 272 can be smaller than the first receiving space 271.In some embodiments, the partition plate arrangement 2826 can also subdivide the interior 2827 of the main housing 2825 by other arrangements, although this is not specifically defined here.

[0302] In some embodiments, the partition plate arrangement 2826 further comprises an inner partition plate 263, wherein the inner partition plate 263 further divides the second receiving chamber 272 into two partial receiving chambers 2721. In particular, the inner partition plate 263 is arranged perpendicular to the bottom wall 252 of the main housing 2825 and is connected to the side partition plate 261 and the circumferential wall 251, and further extends to a wiring opening 2621, so that the second receiving chamber 272 is divided into two partial receiving chambers 2721 and the wiring opening 2621 is also divided into two areas, wherein the two wiring openings 2621 can each be connected to a corresponding partial receiving chamber 2721.

[0303] In some embodiments, the second receiving chamber 272 can also be filled with sealant. This allows the conductors 2812 and 80 housed in the second receiving chamber 272 to be further secured, thus reducing the adverse effects on sound quality caused by the conductors' vibrations. This improves the sound quality of the loudspeaker arrangement. Furthermore, a weld joint between conductor 2812 and conductor 80 can be protected. In addition, the sealed design of the second receiving chamber 272 provides protection against water and dust.

[0304] It should be noted that the above description of the loudspeaker arrangement provides only detailed examples and should not be considered the only possible embodiment. For those skilled in the art, it is obvious, based on the understanding of the basic principle of the loudspeaker arrangement, that various modifications and changes to the loudspeaker arrangement can be made with regard to the methods and steps for its implementation, including its design and details, without deviating from this principle. These modifications and changes, however, still fall within the scope described above. For example, the second recording chamber 272 can also be larger than the first recording chamber 271, or the second recording chamber 272 can be the same as the first recording chamber 271. Such variations are within the scope of protection of the present application.

[0305] In some embodiments, the loudspeaker arrangement described above can transmit sound to the user via bone conduction and / or air conduction. When sound is transmitted via air conduction, the loudspeaker arrangement can include one or more sound sources. The sound source can be located at a specific position on the user's head, for example, on the top of the head, forehead, cheek, temple, auricle, or the back of the auricle, without obstructing or covering the ear canal. For illustration, [Figure 1] shows Fig. 35 a schematic diagram of sound transmission via air duct.

[0306] As in Fig.As shown in Figure 35, a sound source 2810 and a sound source 2820 can generate sound waves with opposite phases (this opposite relationship is indicated in the figure by “+” and “-”). For simplicity, the sound sources mentioned here refer to sound outlets on the loudspeaker assembly that emit sound. For example, the sound source 2810 and the sound source 2820 can be two sound outlets, each located at specific positions on the loudspeaker assembly, for example, on the core housing 41 or on the temple 15.

[0307] In some embodiments, the sound source 2810 and the sound source 2820 can be generated by a common vibration device 2801. The vibration device 2801 comprises a diaphragm (not shown in the figure). When the diaphragm is set into vibration by an electrical signal, the front side of the diaphragm causes the air to vibrate and, via a sound conduction channel 3112 at a sound outlet, forms the sound source 2810, while the back side of the diaphragm causes the air to vibrate and, via the sound conduction channel 3122 at a sound outlet, forms the sound source 2820. The sound conduction channel defines a propagation path for the sound from the diaphragm to the corresponding sound outlet. In some embodiments, the sound conduction channel is a path formed by certain structures on the loudspeaker, for example, by the core housing 41 or the temple 15.It should be noted that in some alternative embodiments, the sound source 2810 and the sound source 2820 can also be generated by different vibration devices, namely by vibrations of different membranes.

[0308] Part of the sound generated by sound sources 2810 and 2820 is transmitted to the user's ear and constitutes the sound perceived by the user, while another part is transmitted into the environment and results in sound loss. Given that sound sources 2810 and 2820 are located at a relatively short distance from the user's ear, the sound transmitted to the user's ear can, for simplicity, be referred to as near-field sound, while the sound loss transmitted into the environment can be referred to as far-field sound. In some embodiments, the near-field / far-field sound generated by the loudspeaker arrangement at different frequencies correlates with the distance between sound source 2810 and sound source 2820.In general, the near-field sound produced by the loudspeaker arrangement increases with increasing distance between the two sound sources, while the far-field sound produced (sound loss) increases with increasing frequency.

[0309] For sound of different frequencies, the distance between sound source 2810 and sound source 2820 can be specifically designed so that the low-frequency near-field sound (e.g., sound with a frequency below 800 Hz) generated by the loudspeaker arrangement is as strong as possible and the high-frequency far-field sound (e.g., sound with a frequency above 2000 Hz) is as weak as possible. To achieve this, the loudspeaker arrangement can comprise two or more groups of dual sound sources, each group comprising two sound sources similar to sound sources 2810 and 2820, each generating sound of specific frequencies. In particular, the first group of dual sound sources can be used to generate low-frequency sound, while the second group of dual sound sources is intended for generating high-frequency sound.To obtain a stronger low-frequency near-field sound, the distance between the two sound sources in the first group of dual sound sources can be increased. Since the wavelength of a low-frequency signal is relatively long, a greater distance between the two sound sources does not result in an excessively large phase difference in the far field and therefore does not produce excessive sound loss in the far field. To keep high-frequency far-field sound weak, the distance between the two sound sources in the second group of dual sound sources can be decreased. Since the wavelength of a high-frequency signal is relatively short, a smaller distance between the two sound sources avoids large phase differences in the far field and thus prevents significant sound loss.The distance between the sound sources of the second group of dual sound sources is smaller than the distance between the sound sources of the first group of dual sound sources.

[0310] The advantageous effects achievable by the embodiments of the present application include, but are not limited to: (1) The rotating shaft arrangement allows the spectacle frame and temple to be connected to each other, thus protecting the connecting wire in the spectacles and extending its service life; (2) the soft circuit board simplifies the wiring in the loudspeaker; (3) filling the second receiving chamber with sealant allows the wires arranged therein to be fixed, reducing the effects of wire vibrations on sound quality and thus improving the sound quality of the loudspeaker. Furthermore, the sealant in the second receiving chamber protects the welds between the wires, and the sealed second receiving chamber provides protection against water and dust.(4) The rigid support plate presses the waterproof membrane assembly, which has a waterproof and sound-transmitting effect, against the first sound inlet opening, covering it and lying tightly against the inner surface of the core housing to prevent liquid from outside the core housing from entering the interior of the core housing through the first sound inlet opening, thus improving the waterproofness of the microphone; and (5) the effect of the microphone assembly with respect to the detection of sound from the main sound source is improved. It should be noted that the advantageous effects achievable in different embodiments may vary. In the different embodiments, the achievable advantageous effects may include any of the effects described above, a combination of several of them, or other achievable advantageous effects.

[0311] The basic concepts have been described above. Naturally, the above disclosure of the invention is provided to the person skilled in the art only as an example, without limiting the application. Although not explicitly stated, a person skilled in the art may make various modifications, improvements, and changes to the application. These modifications, improvements, and changes are indicated in the application so that they are still within the spirit and scope of the exemplary embodiments presented in the application.
