[0002] The conventional wireless microphone transmitter is often limited in design by the diversity of installation methods, resulting in a large overall volume. The root cause of this problem is that the conventional cover installation method mainly relies on screw locking. The volume of the screw itself occupies a large space, and there are corresponding screw holes and studs, which not only occupy the space inside the shell, but also compress the storage area of the electrical elements inside the shell, making the entire device appear bulky. This larger volume makes the device appear not to fit when hung on the collar or chest position of the clothes, appearing conspicuous on the appearance, and due to its own weight, there is a certain risk of accidental falling, greatly limiting the flexibility and convenience of the device in actual application. In addition, how to improve the performance of the microphone receiver and the microphone is also an important topic in the industry. SUMMARY

[0049] Compared to existing technologies, in the transmitter of this application, the mounting slot is used to confine the microphone core and prevent it from becoming loose. The mounting cavity is used to confine the PCB board and prevent it from becoming loose. By using pins to connect the microphone core and the PCB board, the short pin length eliminates the space occupied by the leads, optimizes the structure, and makes the overall structure of the transmitter more compact, thus preventing pin loosening.

Then, the torsion spring is gradually pushed between the stop and the limiting seat, which respectively limit the torsion spring's position, preventing it from shifting. Finally, the rotating shaft is passed sequentially through the first connecting hole, the second connecting hole, and the middle of the torsion spring, thereby fixing the torsion spring and simultaneously hinged the microphone body and the clamping block. By setting the stop and the limiting seat, the installation efficiency of the torsion spring, the rotating shaft, the clamping block, and the microphone body can be improved, resulting in high assembly precision.

The function switch is located within the mounting cavity 10a and connected to the housing 10, and the function switch includes at least one of a gain adjustment switch and a volume adjustment switch. The adjustment assembly 20 is rotatably connected to the housing 10 corresponding to the mounting hole 10b, and the adjustment assembly 20 is also connected to the function switch; rotation of the adjustment assembly 20 adjusts the position of the function switch.

[0121] The specific structure of the wireless microphone receiver 1 will be described in detail below with reference to Figures 5-10.

[0122] As shown in Figures 5-7, the wireless microphone receiver 1 includes a housing 10, a function switch, and an adjustment component 20.

[0123] The housing 10 serves as the outer shell of the wireless microphone receiver 1. The housing 10 has a mounting cavity 10a and a mounting hole 10b communicating with the mounting cavity 10a. The specific material used to manufacture the housing 10 is not limited here; designers can make a reasonable selection based on actual needs. For example, the material used to manufacture the housing 10 can be, but is not limited to, plastic or PVC; such raw materials are widely available and easy to obtain, and can effectively reduce the cost of the wireless microphone receiver 1. The specific structure of the housing 10 is not limited here; designers can make a reasonable design based on actual needs. For example, the housing 10 includes a front shell 11 and a rear cover 12. The front shell 11 has the aforementioned mounting hole 10b, and the rear cover 12 is connected to the front shell 11 and together with the front shell 11 encloses the aforementioned mounting cavity 10a.

[0124] As shown in Figures 5-7, the function switch serves as the function key of the wireless microphone receiver 1. The function switch includes at least one of a gain adjustment switch and a volume adjustment switch. For example, the function switch may only include a gain adjustment switch; for another example, the function switch may only include a volume adjustment switch; for yet another example, the function switch may include both a gain adjustment switch and a volume adjustment switch.

[0125] The function switch is located in the mounting cavity 10a of the housing 10 and is connected to the housing 10. The specific connection method between the function switch and the housing 10 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the function switch can be detachably connected to the housing 10 by at least one of the following methods: screw connection, snap connection or plug connection. For another example, the function switch can also be non-detachably connected to the housing 10 by adhesive bonding.

[0126] As shown in Figures 5-7, the adjustment component 20 serves as the adjustment mechanism of the wireless microphone receiver 1 to adjust the level of the function switch to meet the user's needs in different scenarios; the specific structure of the adjustment component 20 will be described in detail below.

[0127] The adjusting component 20 is rotatably connected to the housing 10 via the mounting hole 10b. The adjusting component 20 is connected to the function switch, and its rotation adjusts the switch's position. For example, the function switch may have a zero position, and three positions arranged sequentially from low to high. By gradually rotating the adjusting component 20 clockwise, the function switch can be sequentially switched from the zero position to the first position, from the first position to the second position, and from the second position to the third position. Conversely, by gradually rotating the adjusting component 20 counterclockwise, the function switch can be sequentially switched from the third position to the second position, from the second position to the first position, and from the first position to the zero position. It should be noted that the adjusting component 20 can be rotated to switch the function switch from the zero position to any position, or from any position to any other position.

[0128] Based on the wireless microphone receiver 1 in this embodiment, by designing the adjustment component 20 and the function switch, the user can directly switch the function switch positions by rotating the adjustment component 20 to achieve gain and / or volume adjustment. This eliminates the need for a user terminal to adjust gain and volume, making operation simple and convenient for users. By integrating the function switch into the wireless microphone receiver 1, the noise generated by the mechanical vibration of the user rotating the adjustment component 20 will not affect the wireless microphone transmitter 2, effectively optimizing the sound reception performance of the wireless microphone transmitter 2.

[0129] As shown in Figures 6-8, a damping part is provided on the outer wall of the housing 10 corresponding to the edge of the mounting hole 10b. The adjustment assembly 20 includes a rotating disk 21 and an elastic element 23; the rotating disk 21 is rotatably connected to the housing 10 corresponding to the mounting hole 10b, and the rotating disk 21 is also connected to a function switch; the elastic element 23 is disposed on the side of the rotating disk 21 facing the mounting hole 10b. During at least part of the relative rotation of the rotating disk 21 and the housing 10, the elastic element 23 rubs against the damping part.

[0130] The rotating disk 21 serves as a connector for the adjustment assembly 20. The rotating disk 21 is used to rotatably connect with the housing 10 on one hand and to connect with the function switch on the other. The specific structure of the rotating disk 21 will be described in detail below.

[0131] The elastic element 23 serves as a damping element in the adjustment assembly 20 and is used to dampen the damping part. The elastic element 23 may include, but is not limited to, a spring sheet 231 or an elastic protrusion. It is understood that the specific form of the damping part that dampens the elastic element 23 may vary depending on the specific form of the elastic element 23.

[0132] By providing an elastic element 23 on the side of the rotating disk 21 facing the mounting hole 10b, and providing a damping part on the outer wall of the housing 10 corresponding to the edge of the mounting hole 10b, and achieving damping through the friction between the elastic element 23 and the damping part, the stability of the rotating disk 21 and the housing 10 during relative rotation can be effectively enhanced, thereby improving the stability of the function switch gear adjustment.

[0133] As shown in Figures 6-8, the elastic element 23 includes a spring sheet 231; the spring sheet 231 is cantilevered and connected to the rotating disk 21 (that is, one end of the spring sheet 231 is connected to the rotating disk 21, and the other end of the spring sheet 231 is suspended), and part of the spring sheet 231 is in contact with the damping part.

[0134] The specific shape of the spring piece 231 is not limited here; designers can design it reasonably according to actual needs. For example, the spring piece 231 can be, but is not limited to, an arc-shaped spring piece 231 or a straight spring piece 231. The specific connection method between the spring piece 231 and the rotating disk 21 (specifically, the rotating body 211 described below) is not limited here; designers can design it reasonably according to actual needs. For example, the spring piece 231 can be detachably connected to the rotating disk 21 by at least one of the following methods: screw connection, snap connection, or plug connection. Alternatively, the spring piece 231 can also be non-detachably connected to the rotating disk 21 by means of adhesive bonding, riveting, injection molding, or 3D printing, but is not limited to such methods.

[0135] By designing the elastic element 23 as a spring sheet 231, during at least a portion of the relative rotation of the rotating disk 21 and the housing 10, the spring sheet 231 rotates relative to the damping part and rubs against it. The damping part compresses the spring sheet 231, causing it to deform. This deformation generates a spring force that hinders the continued rotation of the damping part, thus impeding the relative rotation between the rotating disk 21 and the housing 10. This makes the rotation of the rotating disk 21 smoother, improving the stability of the function switch position adjustment. Designing the elastic element 23 as a spring sheet 231 further ensures the damping effect, simplifies the mechanism, and facilitates manufacturing. By designing a portion of the spring sheet 231 to contact the damping part, it ensures that the spring sheet 231 provides sufficient spring force while further reducing wear during the friction process between the spring sheet 231 and the damping part.

[0136] As shown in Figures 6-8, to ensure smoother rotation of the rotating disk 21, the design incorporates multiple spring pieces 231, evenly distributed around the axis of the mounting hole 10b; and multiple damping parts, also evenly distributed around the axis of the mounting hole 10b. The number of spring pieces 231 can be, but is not limited to, two, three, four, five, six, or more; the number of damping parts can be, but is not limited to, two, three, four, five, six, or more. For example, in this embodiment, there are four spring pieces 231, which are evenly distributed around the axis of the mounting hole 10b (i.e., one spring piece 231 is designed every 90 degrees); there are also four damping parts, which are also evenly distributed around the axis of the mounting hole 10b (i.e., one damping part is designed every 90 degrees); and each spring piece 231 corresponds to one damping part, so that when the rotating disk 21 and the housing 10 rotate relative to each other by a preset angle, each spring piece 231 only rubs against the corresponding damping part.

[0137] As shown in Figures 6-8, the damping section includes multiple damping grooves 10c arranged along the edge of the mounting hole 10b; the free end of the spring piece 231 protrudes towards the mounting hole 10b and forms a damping ball 2311, which abuts against the groove wall of the damping groove 10c. During at least part of the relative rotation of the rotating disk 21 and the housing 10, the damping ball 2311 abuts against the groove wall of different damping grooves 10c in sequence. The groove wall of the damping groove 10c compresses the damping ball 2311, causing the spring piece 231 to deform. This deformation generates a spring force that hinders the continued rotation of the damping groove 10c, thereby hindering the relative rotation between the rotating disk 21 and the housing 10, making the rotation of the rotating disk 21 more stable, and improving the stability of the function switch gear adjustment.

[0138] As shown in Figures 6-8, the rotating disk 21 (specifically the rotating body 211 described below) has a through hole 21a; most of the spring piece 231 is located inside the through hole 21a, and the spring piece 231 is cantilevered and connected to the hole wall of the through hole 21a, and the damping ball 2311 at the free end of the spring arm extends to the outside of the through hole 21a.

[0139] As shown in Figure 6, the housing 10 (specifically the front housing 11 mentioned above) includes a housing body 111 and a convex ring 112; the housing body 111 has the aforementioned mounting cavity 10a and the aforementioned mounting hole 10b; the convex ring 112 is disposed on the outer wall of the housing body 111 and surrounds the mounting hole 10b; the aforementioned damping groove 10c is disposed on the convex ring 112.

[0140] Of course, the damping section may also include multiple damping protrusions (not shown in the figure) provided along the edge of the mounting hole 10b; the free end of the spring piece 231 is recessed away from the mounting hole 10b to form a damping groove (not shown in the figure), and the groove wall of the damping groove abuts against the damping protrusions. During at least part of the relative rotation of the rotating disk 21 and the housing 10, the groove wall of the damping groove abuts against different damping protrusions in sequence. The damping protrusions squeeze the groove wall of the damping groove, causing the spring piece 231 to deform. This deformation generates a spring force that hinders the damping protrusions from continuing to rotate, thereby hindering the relative rotation between the rotating disk 21 and the housing 10, making the rotation of the rotating disk 21 more stable, so as to improve the stability of the function switch gear adjustment.

[0141] As shown in Figures 6-8, the rotating disk 21 includes a rotating body 211, a connecting part 212, and a driving part 213. The rotating body 211 covers at least part of the mounting hole 10b; an elastic member 23 is disposed on the side of the rotating body 211 facing the mounting hole 10b. The connecting part 212 is disposed on the side of the rotating body 211 facing the mounting hole 10b; the rotating body 211 is rotatably connected to the housing 10 through the connecting part 212. The driving part 213 is disposed on the side of the rotating body 211 facing the mounting hole 10b, and the driving part 213 is connected to a function switch.

[0142] The rotating body 211 serves as the main load-bearing component of the rotating disk 21. The specific structure of the rotating body 211 is not limited here; designers can design it appropriately according to actual needs. For example, the rotating body 211 can, but is not limited to, a disk-shaped structure. Along the axis of the mounting hole 10b, the projection of the rotating disk 21 onto the plane containing the opening of the mounting hole 10b can partially or completely cover the opening of the mounting hole 10b.

[0143] The connecting part 212 serves as one of the connecting parts of the rotating disk 21 and is used to connect with the housing 10 to achieve a rotational connection between the rotating disk 21 and the housing 10. Here, the specific connection method between the connecting part 212 and the rotating body 211 is not limited, and the designer can make a reasonable design according to actual needs. For example, when the connecting part 212 and the rotating body 211 are separate structures, the connecting part 212 can be detachably connected to the rotating body 211 by at least one of the following methods: screw connection, snap connection, or plug connection. The connecting part 212 can also be non-detachably connected to the rotating body 211 by adhesive bonding or riveting. For another example, when the connecting part 212 and the rotating body 211 are integral structures, the connecting part 212 can be integrally formed with the rotating body 211 by injection molding or 3D printing.

[0144] The drive unit 213, serving as another connecting part 212 of the rotating disk 21, is used to connect with a function switch to adjust the function switch's position by rotating the rotating disk 21. The drive unit 213 may include a drive rod; one end of the drive rod is connected to the rotating body 211, and the other end is connected to the function switch. The specific connection method between the drive unit 213 and the rotating body 211 is not limited here; designers can design it reasonably according to actual needs. For example, when the drive unit 213 and the rotating body 211 are separate structures, the drive unit 213 can be detachably connected to the rotating body 211 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the drive unit 213 can be non-detachably connected to the rotating body 211 by adhesive bonding or riveting. Furthermore, when the drive unit 213 and the rotating body 211 are an integral structure, the drive unit 213 can be integrally formed with the rotating body 211 by injection molding or 3D printing, but is not limited to this method.

[0145] By designing a rotating body 211, a connecting part 212, and a driving part 213, the rotating body 211, the connecting part 212, and the driving part 213 cooperate to realize the rotational connection between the knob cover 24 and the housing 10, as well as the connection between the knob cover 24 and the function switch. The structure is simple and easy to process.

[0146] As shown in Figures 6-8, the connecting part 212 includes a hook 2121; the fixed end of the hook 2121 is connected to the rotating body 211, and the hooking end of the hook 2121 passes through the mounting hole 10b and hooks onto the housing 10. The number of hooks 2121 can be one or more (two or more). For example, in this embodiment, the number of hooks 2121 is four, and the four hooks 2121 are evenly distributed around the axis of the mounting hole 10b. During the installation of the rotating disk 21, as the hook 2121 passes through the mounting hole 10b, the wall of the mounting hole 10b presses against the hook 2121, causing it to elastically deform in a direction biased towards the axis of the mounting hole 10b. After the hook end of the hook 2121 passes through the mounting hole 10b and disengages from the hole wall, the hook 2121, under the action of the elastic restoring force corresponding to the elastic deformation, recovers its deformation in a direction biased towards the axis of the mounting hole 10b. At this point, the hook end of the hook 2121 is hooked onto the housing 10, thus achieving the installation between the rotating disk 21 and the housing 10. It should be noted that there is a gap between the hook end of the hook 2121 and the inner wall of the housing 10 corresponding to the edge of the mounting hole 10b, allowing the rotating disk 21 to rotate relative to the housing 10 under the action of external force.

[0147] Of course, the connecting part 212 may also include a rotating shaft (not shown in the figure); one end of the rotating shaft is connected to the rotating body 211, and the other end of the rotating shaft is connected to the housing 10; thus, a rotational connection between the rotating disk 21 and the housing 10 can be realized.

[0148] As shown in Figures 6 and 7, the adjustment assembly 20 also includes a knob cover 24; the knob cover 24 covers the mounting hole 10b and is connected to the rotating disk 21. The specific connection method between the knob cover 24 and the rotating disk 21 is not limited here; designers can design it reasonably according to actual needs. For example, the knob cover 24 can be detachably connected to the rotating disk 21 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the knob cover 24 can be non-detachably connected to the rotating disk 21 by adhesive bonding or riveting. By designing the knob cover 24, the mounting hole 10b is sealed, thus achieving effective waterproofing and dustproofing. Of course, the periphery of the knob cover 24 is also provided with anti-slip texture 241, making it easier for the user to rotate the knob cover 24.

[0149] Other structural designs for the wireless microphone receiver 1 may include, but are not limited to, one or more of the following embodiments.

[0150] As shown in Figure 9, in the first example, the wireless microphone receiver 1 also includes a function indicator light 31. The function indicator light 31 is disposed on the top wall of the housing 10 and is used to indicate the current state of the function switch. The function indicator light 31 can be detachably connected to the top wall of the housing 10 by at least one of the following methods: screwing, snap-fitting, or plugging. When the function indicator light 31 is lit, it indicates that the function switch is in the working state (i.e., in any of the first, second, and third positions mentioned above); when the function indicator light 31 is off, it indicates that the function switch is in the non-working state (i.e., in the zero position mentioned above). By designing the function indicator light 31, the user can confirm the current state of the function switch according to the function indicator light 31, improving the ease of use of the wireless microphone receiver 1.

[0151] As shown in Figure 9, in the second example, the wireless microphone receiver 1 also includes an adjustment level indicator 32. The adjustment level indicator 32 is disposed on the housing 10 and located below the adjustment assembly 20, and is used to indicate the position of the function switch. The adjustment level indicator 32 can be detachably connected to the side wall of the housing 10 by at least one of the following methods: screwing, snap-fitting, or plugging. The adjustment level indicator 32 includes multiple LEDs; for example, if the adjustment level indicator 32 includes three LEDs, when one LED is lit, it indicates that the function switch is in the first position; when two LEDs are lit, it indicates that the function switch is in the second position; and when all three LEDs are lit, it indicates that the function switch is in the third position. By designing the adjustment level indicator 32, the user can confirm the position of the function switch according to the adjustment level indicator 32, improving the ease of use of the wireless microphone receiver 1.

[0152] As shown in Figure 9, in the third example, the wireless microphone receiver 1 also includes a noise-canceling button 33 and an external interface 34 for connecting to an external electronic device; the noise-canceling button 33 and the external interface 34 are disposed on the first side wall of the housing 10. The type of the external interface 34 can be, but is not limited to, a USB-A interface, a USB-C interface, or a Type-C interface, etc. By designing the noise-canceling button 33, users can select to trigger the noise-canceling button 33 according to the actual application scenario to reduce noise and improve clarity. By designing the external interface 34, the wireless microphone receiver 1 can be connected to external electronic devices such as cameras through the external interface 34, improving the ease of use of the wireless microphone receiver 1.

[0153] As shown in Figure 10, in the fourth example, the wireless microphone receiver 1 also includes a 3.5mm interface 35 and a mono / stereo switch button 36; the 3.5mm interface 35 and the mono / stereo switch button 36 are located on the second side wall of the housing 10. The 3.5mm interface 35 enhances the practicality of the wireless microphone receiver 1. The mono / stereo switch button 36 allows users to select and trigger the button to switch between different channels according to the actual application scenario, improving the ease of use of the wireless microphone receiver 1.

[0154] As shown in Figure 10, in the fifth example, the wireless microphone receiver 1 also includes a charging interface 37; the charging interface 37 is disposed on the bottom wall of the housing 10. By designing the charging interface 37, when the power of the wireless microphone receiver 1 is too low or zero, the wireless microphone charging case 3 can effectively charge the wireless microphone receiver 1 through the charging interface 37.

[0155] As shown in Figures 5 and 6, in the sixth example, the wireless microphone receiver 1 further includes a lapel clip structure 38; the lapel clip structure 38 is disposed on the side wall of the housing 10 opposite to the adjustment component 20. The lapel clip structure 38 may include, but is not limited to, a rotating shaft 381, a clip body 382, ​​and a torsion spring 383; the rotating shaft 381 is rotatably connected to the housing 10 (specifically, the aforementioned rear cover 12); the clip body 382 is rotatably connected to the rotating shaft 381; the torsion spring 383 is sleeved on the rotating shaft 381, with one end of the torsion spring 383 abutting against the housing 10 and the other end abutting against the clip body 382. By designing the lapel clip structure 38, the wireless microphone receiver 1 can be directly worn on the user's collar, freeing the user's hands and improving the ease of use of the wireless microphone receiver 1.

[0156] Referring to Figure 11, in a second aspect, this application proposes a wireless microphone charging system, which includes a wireless microphone charging case 3, a wireless microphone transmitter 2, and the aforementioned wireless microphone receiver 1; the wireless microphone charging case 3 has a first charging slot and a second charging slot; the wireless microphone transmitter 2 is installed in the first charging slot; and the wireless microphone receiver 1 is installed in the second charging slot.

[0157] Based on the wireless microphone charging system in this application embodiment, which has the aforementioned wireless microphone receiver 1, the user can directly switch the function switch position by rotating the adjustment component 20 to achieve gain and / or volume adjustment. Thus, there is no need to use a terminal to adjust the gain and volume, making the operation simple and convenient for the user.

[0158] Third Embodiment

[0159] Referring to Figures 12 to 14, an embodiment of this application provides a microphone transmitter housing, including a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are combined to form a cavity 3 for accommodating a microphone transmitting device. A snap-fit ​​rib 4 is provided extending from the edge of the first housing 1, and a snap-fit ​​groove 5 is provided extending from the inner wall of the second housing 2. The snap-fit ​​rib 4 and the snap-fit ​​groove 5 can be snapped together. Alternatively, the snap-fit ​​groove 5 is provided extending from the inner wall of the first housing 1, and the snap-fit ​​rib 4 is provided extending from the edge of the second housing 2. The snap-fit ​​rib 4 and the snap-fit ​​groove 5 can be snapped together.

[0160] In this embodiment, the first housing 1 and the second housing 2 are joined together by a snap-fit ​​rib 4 and a snap-fit ​​groove 5. When combined, they form a wall for accommodating a microphone transmitting device. It can be understood that the snap-fit ​​rib 4 can be set on the edge of the first housing 1 or the edge of the second housing 2. When the snap-fit ​​rib 4 extends along the edge of the first housing 1, the snap-fit ​​groove 5 extends along the inner wall of the second housing 2. When the snap-fit ​​rib 4 extends along the edge of the second housing 2, the snap-fit ​​groove 5 extends along the inner wall of the first housing 1. It is easy to imagine that both the snap-fit ​​rib 4 and the snap-fit ​​groove 5 are arc-shaped and have the same inner diameter, which can ensure the stability of the snap-fit. In addition, this embodiment uses an integrated edge as the snap-fit ​​connection structure to realize a long edge snap-fit ​​structure in a limited space, improve the volume of the snap-fit, and thus achieve the stability of the snap-fit ​​and prevent loosening.

[0161] In one embodiment, a limiting groove 6 is provided between the snap-fit ​​rib 4 and the edge of the first housing 1, or between the snap-fit ​​rib 4 and the edge of the second housing 2. That is, the cross-section of the snap-fit ​​rib 4 is L-shaped, and there is a certain surface difference between the snap-fit ​​rib 4 and the edge of the first housing 1 or the second housing 2. After snap-fitting, the snap-fit ​​rib 4 is better limited to prevent loosening between the first housing 1 and the second housing 2.

[0162] In one embodiment, an engagement portion 7 is provided between the snap-fit ​​groove 5 and the edge of the second housing 2, or the engagement portion 7 is provided between the snap-fit ​​groove 5 and the edge of the first housing 1. When the first housing 1 and the second housing 2 are snapped together, the engagement portion 7 is located in the limiting groove 6. It can be understood that the engagement portion 7 is used to engage in the limiting groove 6. After snapping together, it better limits the snap-fit ​​rib 4 and prevents the first housing 1 and the second housing 2 from loosening.

[0163] In one embodiment, as shown in FIG13, the surface of the biting part 7 that abuts against the snapping rib 4 is an inclined abutting surface 8. Taking the snapping rib 4 extending along the edge of the first housing 1 and the snapping groove 5 extending along the inner wall of the second housing 2 as an example, when the first housing 1 and the second housing 2 are snapped together, the snapping rib 4 and the biting part 7 will contact each other first. After contact, the snapping rib 4 needs to continue to move towards the snapping groove 5 until the snapping rib 4 is completely inside the snapping groove 5. Therefore, setting the surface of the biting part 7 that first abuts against the snapping rib 4 as an inclined surface can facilitate pushing the snapping rib 4 into the snapping groove 5, achieving the purpose of saving effort and speed.

[0164] In one embodiment, referring to Figures 12-14, after the first housing 1 and the second housing 2 are snapped together to form a microphone transmitter housing, the microphone transmitter housing is provided with a first mounting groove 9, a second mounting groove 10 and a third mounting groove 11. The first mounting groove 9 and the second mounting groove 10 are disposed opposite each other at both ends of the microphone transmitter housing, and the third mounting groove 11 is disposed on the side of the microphone transmitter housing. The first mounting groove 9 is used to install the microphone core of the microphone transmitter, the second mounting groove 10 is used for the connector of the microphone transmitter, and the third mounting groove 11 is used to install the button of the microphone transmitter.

[0165] In one embodiment, as shown in FIG13, a mounting part 12 is provided on the outer side of the first housing 1 or the second housing 2, and a mounting hole 13 is provided on the mounting part 12. The cooperation between the mounting part 12 and the mounting hole 13 can facilitate the installation of a fixing device. The fixing device can be, for example, a clamp or a spring buckle, which can be used to clamp and fix the microphone transmitter housing to the user's clothing or other parts, thereby making the microphone transmitter housing easy to carry.

[0166] Fourth embodiment

[0167] Referring to Figures 15 to 17, an embodiment of this application proposes a transmitter 100, including a housing 10, a microphone 20, a PCB board 30, and pins 40. The housing 10 is provided with a mounting groove 11 and a mounting cavity 12. The microphone 20 is disposed in the mounting groove 11, the PCB board 30 is disposed in the mounting cavity 12, and the pins 40 are disposed on the microphone 20. The microphone 20 and the PCB board 30 are abutted and electrically connected through the pins 40.

[0168] During installation, the PCB board 30 is first placed in the preset position of the mounting cavity 12, then the microphone 20 is placed in the mounting slot 11. The pins 40 of the microphone 20 are pulled out of the mounting slot 11 and extended to the solder pads of the PCB. Finally, they are soldered, thus completing the direct soldering of the pins 40 inside the housing 10. Compared with the traditional lead wire connection method, in the transmitter 100 of this embodiment, the mounting slot 11 is used to restrict the microphone 20 and prevent it from becoming loose. The mounting cavity 12 is used to restrict the PCB board 30 and prevent it from becoming loose. By using pins 40 to connect the microphone 20 and the PCB board 30 to abut and be electrically connected, the short length of the pins 40 eliminates the space occupied by the leads, optimizes the structure, and makes the overall structure of the transmitter 100 more compact, thus preventing the pins 40 from becoming loose. On the other hand, the direct soldering of the pins 40 to the PCB board 30 greatly reduces the transmission loss of the audio signal generated by the microphone 20, effectively realizes the original sound recording restoration, and improves the acoustic performance of the transmitter 100.

[0169] Furthermore, the method of mounting the microphone core 20 by soldering the pins 40 inside the housing 10 allows the housing 10 to replace a dedicated soldering fixture. The microphone core 20 does not need to be assembled after being soldered to the PCB board 30 externally. The soldering process can be performed simply by placing the microphone core 20 and the PCB board 30 in the corresponding positions. Compared with the positional deviation caused by external direct soldering, which makes it impossible for the microphone core 20 to be installed in the corresponding position of the housing 10, the direct soldering solution inside the housing 10 provided in this embodiment effectively improves the ease of installation and yield of the microphone core 20, and effectively improves the manufacturing efficiency of the transmitter 100.

[0170] In one embodiment, the mounting cavity 12 is provided with a support column 121 and / or a support plate 122, and the PCB board 30 is mounted on the support column 121 and / or the support plate 122.

[0171] In one embodiment, the end of the support column 121 is provided with a first positioning column 1211, and the PCB board 30 is provided with a positioning groove 31 that cooperates with the first positioning column 1211. By providing the first positioning column 1211 and the positioning groove 31, phenomena such as loosening of the PCB board 30 can be further avoided.

[0172] In one embodiment, the sidewall of the mounting cavity 12 is provided with a limiting rib 123, and the end of the PCB board 30 is provided with a first limiting notch 32 that cooperates with the limiting rib 123.

A mounting hole 13 is provided on the housing 10, communicating with the mounting cavity 12. The control button 50 is mounted in the mounting hole 13 and is in contact with the PCB board 30. The control button 50 has a second limiting notch 51 that cooperates with the limiting post 124. The control button 50 allows for touch operation on the PCB board 30. The mounting hole 13 is used to mount the control button 50, and the cooperation of the limiting post 124 and the second limiting notch 51 prevents the control button 50 from becoming loose.

[0174] It is understood that in some embodiments, the control button 50 can be omitted, and operation and control can be performed directly by turning the power on and off.

[0175] In one embodiment, the transmitter 100 further includes a sponge mounting base 60, which is disposed on the housing 10 and located at the microphone core 20. The sponge mounting base 60 is provided with a buckle 61, and the housing 10 is provided with a snap-fit ​​groove 14 that mates with the buckle 61. Through the engagement of the buckle 61 and the snap-fit ​​groove 14, the sponge mounting base 60 can be detachably mounted to the housing 10.

[0176] In one embodiment, the cross-section of the snap-fit ​​groove 14 is T-shaped. Since the snap-fit ​​groove 14 is T-shaped, it is convenient to install and lock the buckle 61 and the snap-fit ​​groove 14.

[0177] In one embodiment, the snap-fit ​​groove 14 includes a first hole 141 and a second hole 142. The first hole 141 is located on a first surface of the housing 10, and the second hole 142 is located on a second surface of the housing 10. The first hole 141 and the second hole 142 are connected. By providing the first hole 141 and the second hole 142, it is convenient to operate the snap-fit ​​61.

[0180] Embodiments of this application also provide a microphone, including the transmitter 100 described above. The microphone of this embodiment also has the advantages described above, which will not be repeated here.

[0181] Fifth embodiment

[0182] Referring to Figures 18 to 20, an embodiment of this application provides a lavalier microphone 100, including a clamping block 10, a microphone body 20, a torsion spring 30, and a rotating shaft 40. The clamping block 10 is provided with a first connecting seat 50, which has a first connecting hole 52. The microphone body 20 is provided with a second connecting seat 60, a stop seat 70, and a limiting seat 80, which has a second connecting hole 62. The rotating shaft 40 passes through the first connecting hole 52 and the second connecting hole 62 to hinge the clamping block 10 and the microphone body 20. The middle part of the torsion spring 30 is sleeved on the rotating shaft 40 and is located between the stop seat 70 and the limiting seat 80. One end of the torsion spring 30 abuts against the clamping block 10, and the other end of the torsion spring 30 abuts against the microphone body 20.

[0183] The torsion spring 30 has a wide end and a narrow end, with the narrow end located in the middle and the wide ends at both ends. When assembling the lavalier microphone 100 of this embodiment, first, one end of the torsion spring 30 contacts the surface of the clamping block 10, and the other end contacts the surface of the microphone body 20. Then, the torsion spring 30 is gradually pushed between the stop seat 70 and the limiting seat 80. The stop seat 70 and the limiting seat 80 respectively limit the torsion spring 30, preventing its installation position from shifting. Finally, the rotating shaft 40 is passed sequentially through the first connecting hole 52, the second connecting hole 62, and the middle of the torsion spring 30, thereby fixing the torsion spring 30 and simultaneously hinged the microphone body 20 and the clamping block 10 together. By setting the stop seat 70 and the limiting seat 80, the installation efficiency of the torsion spring 30, the rotating shaft 40, the clamping block 10, and the microphone body 20 can be improved, resulting in high assembly accuracy.

[0184] In one embodiment, the first connecting seat 50 includes two parallel first connecting blocks 54, which are disposed on the clamping block 10, and each of the two first connecting blocks 54 is provided with a first connecting hole 52; the second connecting seat 60 includes two parallel second connecting blocks 64, which are disposed on the microphone body 20, and each of the two second connecting blocks 64 is provided with a second connecting hole 62; the stop seat 70 and the limiting seat 80 are located between the two second connecting blocks 64; the rotating shaft 40 is mounted between the two first connecting holes 52 and between the two second connecting holes 62, so that the clamping block 10 and the microphone body 20 are hingedly connected. The first connecting blocks 54 and the clamping block 10 can be integrally formed, the second connecting blocks 64 and the outer shell of the microphone body 20 are integrally formed, and the microphone body 20 also includes the main components of the microphone. The pivot 40 is mounted in the first connecting hole 52 of the two first connecting blocks 54, and the pivot 40 is also mounted in the second connecting hole 62 of the two second connecting blocks 64. Therefore, the clamping block 10 and the microphone body 20 are smoothly hinged. Under the action of the torsion spring 30, a clamping force can be generated between the clamping block 10 and the microphone body 20, and the clamping block 10 and the microphone body 20 can be clamped to the user's clothing.

[0185] In one embodiment, the microphone body 20 is further provided with a limiting groove 22, which is located between the stop seat 70 and the limiting seat 80, and the middle part of the torsion spring 30 is located within the limiting groove 22. The limiting groove 22 can accommodate the torsion spring 30, and at the same time, the limiting groove 22 also has a certain limiting effect on the torsion spring 30, thereby further improving the installation efficiency of the lavalier microphone 100 in this embodiment.

[0186] In one embodiment, the two ends of the stop seat 70 are respectively connected to the two second connecting blocks 64. The second connecting blocks 64, the stop seat 70, and the outer shell of the microphone body 20 are integrally formed, which can improve the strength and effectively limit and block the torsion spring 30.

[0187] In one embodiment, the first connecting block 54 has a first clearance groove 542 at one end near the microphone body 20. By providing the first clearance groove 542, interference between the first connecting block 54 and the microphone body 20 is avoided.

[0188] In one embodiment, the microphone body 20 is provided with a second recess 26, which is located in the extending direction of the first connecting block 54. By providing the second recess 26, interference between the first connecting block 54 and the microphone body 20 is further avoided.

[0189] In one embodiment, the microphone body 20 is further provided with a fixing groove 24, which is located on the side of the limiting seat 80 away from the stop seat 70, and the other end of the torsion spring 30 is located in the fixing groove 24. The fixing groove 24 is used to accommodate the other end of the torsion spring 30 and has a limiting effect on the other end of the torsion spring 30 to prevent the other end of the torsion spring 30 from shifting.

[0190] In one embodiment, the limiting seat 80 is located within the fixing groove 24, which facilitates the storage of the other end of the torsion spring 30.

[0191] In one embodiment, the torsion spring 30 includes two parallel spiral coils 32, two first torsion arms 34, and two second torsion arms 36. Each spiral coil 32 has a first torsion arm 34 and a second torsion arm 36 at both ends, and the two first torsion arms 34 are connected. The two spiral coils 32 are respectively sleeved on the rotating shaft 40, the two first torsion arms 34 respectively abut against the clamping block 10, and the two second torsion arms 36 respectively abut against the microphone body 20. This arrangement improves the elasticity of the torsion spring 30 and facilitates the retraction of the second torsion arms 36 into the fixing groove 24, avoiding interference.

[0192] Sixth Embodiment

[0193] Please refer to Figures 21-24. This application embodiment provides a sound receiving guide mechanism 20, which can improve the consistency between the sound quality of the sound wave guided to the sound receiving hole 10a of the microphone body 10 after passing through the sound receiving channel 22a of the annular guide seat 22 and the sound quality of the original sound wave, thereby effectively reducing the degree of sound degradation.

[0194] The sound guiding mechanism 20 is applied to the microphone 1, which includes a microphone body 10 and a sound receiving hole 10a. The sound guiding mechanism 20 includes a base 21 and an annular guide seat 22. The base 21 has a through hole 21a corresponding to the sound receiving hole 10a of the microphone body 10, and the base 21 is used to connect to the microphone body 10. The annular guide seat 22 is connected to the side of the base 21 away from the sound receiving hole 10a of the microphone body 10. The area enclosed by the inner side of the annular guide seat 22 serves as a sound receiving channel 22a, and the outer side of the annular guide seat 22 is provided with a buffer hole 22b communicating with the sound receiving channel 22a.

[0195] The specific structure of the sound guiding mechanism 20 will be described in detail below with reference to Figures 21-27. This sound guiding mechanism 20 is applied to the microphone 1, which includes a microphone body 10 and a sound receiving hole 10a. It should be noted that the microphone 1 can be a wireless microphone 1 or a wired microphone 1.

[0196] As shown in Figures 21-24, the radio guiding mechanism 20 includes a base 21 and an annular guide seat 22.

[0197] The base 21 serves as the base of the radio guiding mechanism 20. The specific structure of the base 21 is not limited here; designers can design it appropriately according to actual needs. For example, the base 21 can be, but is not limited to, a plate-like structure with a circular, elliptical, racetrack-shaped, or rectangular cross-section. The specific material used to manufacture the base 21 is not limited here; designers can design it appropriately according to actual needs. For example, the material used to manufacture the base 21 can be, but is not limited to, plastic or silicone.

[0198] The base 21 has a through hole 21a, which corresponds to the sound receiving hole 10a of the microphone body 10. The specific shape of the through hole 21a is not limited here, and the designer can make a reasonable design according to the actual needs; for example, the shape of the cross-section of the through hole 21a can be, but is not limited to, a circle, an ellipse, a racetrack shape, or a rectangle, etc.

[0199] The base 21 is used to connect to the microphone body 10. The specific connection method between the base 21 and the microphone body 10 is not limited here; designers can design it reasonably according to actual needs. For example, when the connection between the base 21 and the microphone body 10 is detachable, the base 21 can be fixedly connected to the microphone body 10 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, when the connection between the base 21 and the microphone body 10 is non-detachable, the base 21 can be fixedly connected to the microphone body 10 by, but is not limited to, adhesive bonding.

[0200] The annular guide seat 22 serves as a guide for the sound receiving mechanism 20, guiding sound waves through the sound receiving channel 22a of the annular guide seat 22 to the sound receiving hole 10a of the microphone body 10. The specific structure of the annular guide seat 22 will be described in detail below. The specific material used to manufacture the annular guide seat 22 is not limited here; designers can design it appropriately according to actual needs. For example, the material used to manufacture the annular guide seat 22 can be, but is not limited to, plastic or silicone.

[0201] The annular guide seat 22 is connected to the side of the base 21 away from the microphone body 10's receiving hole 10a. The specific connection method between the annular guide seat 22 and the base 21 is not limited here; designers can design it reasonably according to actual needs. For example, when the connection between the annular guide seat 22 and the base 21 is detachable, the annular guide seat 22 can be fixedly connected to the base 21 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, when the connection between the annular guide seat 22 and the base 21 is non-detachable, the annular guide seat 22 can be fixedly connected to the base 21 by, but is not limited to, adhesive bonding. In this embodiment, the annular guide seat 22 and the base 21 are integrally formed; for example, the annular guide seat 22 can be formed into an integral structure with the base 21 by injection molding or 3D printing, but is not limited to.

[0202] The area enclosed by the inner side of the annular guide seat 22 serves as the sound receiving channel 22a. After passing through the sound receiving channel 22a, the sound waves are guided to the sound receiving hole 10a of the microphone body 10.

[0203] The outer surface of the annular guide seat 22 is provided with a buffer hole 22b that communicates with the sound receiving channel 22a. The specific shape of the buffer hole 22b is not limited here, and the designer can make a reasonable design according to the actual needs; for example, the shape of the cross-section of the buffer hole 22b can be, but is not limited to, a circle, a triangle, a rectangle, or a racetrack shape, etc.

[0204] It is understandable that after the sound waves enter the sound receiving channel 22a of the annular guide seat 22, some of the sound waves will inevitably collide with the inner surface of the annular guide seat 22 and be reflected. The propagation path of the reflected sound waves will interfere with the propagation path of the unreflected sound waves, affecting the amplitude and frequency of the unreflected sound waves. This results in a difference in the sound quality of the sound waves that are guided to the sound receiving hole 10a of the microphone body 10 after passing through the sound receiving channel 22a of the annular guide seat 22, compared to the sound quality of the original sound waves (i.e., the sound waves before entering the sound receiving channel 22a of the annular guide seat 22), thus causing sound deterioration.

[0205] Based on the sound-guiding mechanism 20 in this embodiment, when a sound wave enters the sound-receiving channel 22a of the annular guide seat 22, a buffer hole 22b communicating with the sound-receiving channel 22a is designed on the outer side of the annular guide seat 22. This allows the sound wave, which is compressed after being reflected by the inner side of the annular guide seat 22, to be decompressed through the buffer hole 22b. This improves the consistency between the sound quality of the sound wave guided to the sound-receiving hole 10a of the microphone body 10 after passing through the sound-receiving channel 22a of the annular guide seat 22 and the original sound wave, thereby effectively reducing the degree of sound degradation. In addition, due to the presence of the buffer hole 22b, the probability of the sound wave entering the sound-receiving channel 22a of the annular guide seat 22 contacting the inner side of the annular guide seat 22 is greatly reduced. Therefore, the probability of sound wave reflection is reduced, which in turn greatly reduces the probability of sound wave amplitude and frequency disorder, thus also reducing the degree of sound degradation.

[0206] As shown in Figure 24, the annular guide seat 22 includes a guide ring 221 and multiple support columns 222. The guide ring 221 defines a central axis. The multiple support columns 222 are spaced apart around the central axis of the guide ring 221. One end of each support column 222 near the microphone body 10's receiving hole 10a is connected to the base 21, and the other end of each support column 222 away from the microphone body 10's receiving hole 10a is connected to the guide ring 221. The area formed by the inner annular surface of the guide ring 221 and the inner surface of the support columns 222 serves as the aforementioned sound receiving channel 22a, and a buffer hole 22b is formed between the guide ring 221, the base 21, and two adjacent support columns 222.

[0207] The inner surface of the annular guide seat 22 includes the inner annular surface of the guide ring 221 and the inner surface of the support column 222. The annular guide seat 22 and the base 21 are integrally formed by injection molding, and the overall structure after injection molding can be formed by, but is not limited to, the guide ring 221 and the support column 222 by CNC milling machine. In this way, the buffer hole 22b is automatically formed between two adjacent support columns 222.

[0208] By designing a guide ring 221 and multiple support pillars 222, when sound waves enter the sound receiving channel 22a of the annular guide seat 22, the buffer hole 22b formed by the guide ring 221, the base 21 and the two adjacent support pillars 222 can decompress the sound waves that have been compressed after reflection. This improves the consistency between the sound quality of the sound waves that are guided to the sound receiving hole 10a of the microphone body 10 after passing through the sound receiving channel 22a of the annular guide seat 22 and the sound quality of the original sound waves, thereby effectively reducing the degree of sound degradation.

[0209] As shown in Figures 24-25, the end face of the guide ring 221 facing away from the microphone body 10's receiving hole 10a, the inner annular surface of the guide ring 221, and the inner surface of the support column 222 smoothly transition to form an arc-shaped guide surface. From the side away from the microphone body 10's receiving hole 10a to the side close to the microphone body 10's receiving hole 10a, the distance between the arc-shaped guide surface and the central axis of the guide ring 221 gradually decreases. This makes the diameter of the receiving channel 22a of the annular guide seat 22 on the side away from the microphone body 10's receiving hole 10a larger than the diameter of the receiving channel 22a of the annular guide seat 22 on the side close to the microphone body 10's receiving hole 10a, so that the receiving channel 22a of the annular guide seat 22 is conical, which can effectively extract sound from a specific direction from multiple microphones 1 while suppressing noise from other directions.

[0210] As shown in Figures 22, 24, and 25, the outer annular surface of the guide ring 221 is further away from the central axis of the guide ring 221 than the outer surface of the support column 222. The end face of the guide ring 221 facing the microphone body 10's sound-receiving hole 10a smoothly transitions to the outer surface of the support column 222 to form an arc-shaped stepped structure 22c. The microphone 1 also includes a windscreen 30, which is attached to the arc-shaped stepped structure 22c via a connector 40.

[0211] The outer surface of the annular guide seat 22 includes the outer annular surface of the guide ring 221 and the outer surface of the support column 222. The wind shield 30 is used to prevent microphone spraying. The connector 40 may include, but is not limited to, an elastic collar. The opening edge of the wind shield 30 is connected to the elastic collar. The elastic collar deforms under force to pass over the guide ring 221 and fit over multiple support columns 222. The elastic collar contacts the stepped surface of the arc-shaped stepped structure 22c. It should be noted that when the wind shield 30 is attached to the arc-shaped stepped structure 22c via connectors such as the elastic collar 40, the connectors 40 will not completely block the buffer hole 22b. This ensures that the buffer hole 22b formed between the guide ring 221, the base 21, and two adjacent support columns 222 can effectively decompress the compressed sound waves after reflection.

[0212] By designing the end face of the guide ring 221 facing the microphone body 10's sound hole 10a and the outer side of the support column 222 into a smooth transition and forming an arc-shaped step structure 22c, when the windproof cover 30 is hung on the arc-shaped step structure 22c through the connector 40, the step surface of the arc-shaped step structure 22c can limit the connector 40, so as to ensure the effectiveness of the connection between the connector 40 and the annular guide seat 22, and effectively reduce or even avoid the possibility of the windproof cover 30 falling off.

[0213] As shown in Figure 26, the annular guide seat 22 includes a guide ring 221 and a support ring 223; a wire ring defines the central axis; the support ring 223 is located between the guide ring 221 and the base 21, and the support ring 223 is connected to the guide ring 221 and the base 21. The area formed by the inner annular surface of the guide ring 221 and the inner annular surface of the support ring 223 serves as the aforementioned sound receiving channel 22a; the outer annular surface of the support ring 223 is provided with a plurality of buffer holes 22b at one end near the sound receiving hole 10a of the microphone body 10, and all buffer holes 22b are spaced apart around the central axis of the guide ring 221.

[0214] The inner surface of the annular guide seat 22 includes the inner annular surface of the guide ring 221 and the inner annular surface of the support ring 223; the outer surface of the annular guide seat 22 includes the outer annular surface of the guide ring 221 and the outer annular surface of the support ring 223. The annular guide seat 22 and the base 21 are integrally formed by injection molding, and the overall structure after injection molding can, but is not limited to, be formed by stamping with a stamping machine to form the aforementioned buffer hole 22b. The buffer hole 22b can, but is not limited to, be a round hole or a rectangular hole.

[0215] By designing the guide ring 221 and the support ring 223, when the sound wave enters the sound receiving channel 22a of the annular guide seat 22, the multiple buffer holes 22b designed on the outer annular surface of the support ring 223 near the sound receiving hole 10a of the microphone body 10 can decompress the sound wave that has been compressed after reflection. This improves the consistency between the sound quality of the sound wave that is guided to the sound receiving hole 10a of the microphone body 10 after passing through the sound receiving channel 22a of the annular guide seat 22 and the sound quality of the original sound wave, thereby effectively reducing the degree of sound degradation.

[0216] As shown in Figure 27, the annular guide seat 22 includes a guide ring 221 and a support ring 223; the guide ring 221 defines the central axis; the support ring 223 is located between the guide ring 221 and the base 21, and the support ring 223 is connected to the guide ring 221 and the base 21. The area formed by the inner annular surface of the guide ring 221 and the inner annular surface of the support ring 223 serves as the aforementioned sound receiving channel 22a; there are multiple buffer holes 22b, all of which are spaced around the central axis of the guide ring 221, and the buffer holes 22b are elongated holes, extending from one end of the support ring 223 near the sound receiving hole 10a of the microphone body 10 to the end face of the guide ring 221 facing away from the sound receiving hole 10a of the microphone body 10.

[0217] The inner surface of the annular guide seat 22 includes the inner annular surface of the guide ring 221 and the inner annular surface of the support ring 223; the outer surface of the annular guide seat 22 includes the outer annular surface of the guide ring 221 and the outer annular surface of the support ring 223. The annular guide seat 22 and the base 21 are integrally formed by injection molding, and the overall structure after injection molding can be, but is not limited to, formed by machining the aforementioned buffer hole 22b using a CNC milling machine.

[0218] By designing the guide ring 221 and the support ring 223, when the sound wave enters the sound receiving channel 22a of the annular guide seat 22, the multiple elongated holes extending from one end of the support ring 223 near the sound receiving hole 10a of the microphone body 10 to the end face of the guide ring 221 facing away from the sound receiving hole 10a of the microphone body 10 can decompress the sound wave that has been compressed after reflection. This improves the consistency between the sound quality of the sound wave guided to the sound receiving hole 10a of the microphone body 10 after passing through the sound receiving channel 22a of the annular guide seat 22 and the sound quality of the original sound wave, thereby effectively reducing the degree of sound degradation.

[0219] As shown in Figures 26-27, the outer annular surface of the guide ring 221 is further away from the central axis of the guide ring 221 than the outer annular surface of the support ring 223. The end face of the guide ring 221 facing the microphone body 10's sound-receiving hole 10a is perpendicular to the outer annular surface of the support ring 223, forming a right-angled stepped structure 22d. The microphone 1 also includes a windscreen 30, which is attached to the right-angled stepped structure 22d via a connector 40.

[0220] The wind shield 30 is used to prevent popping sounds. The connector 40 may include, but is not limited to, an elastic collar. The opening edge of the wind shield 30 is connected to the elastic collar. The elastic collar deforms under force to pass over the guide ring 221 and fit onto the support ring 223. The elastic collar contacts the stepped surface of the right-angled stepped structure 22d. It should be noted that, for the multiple buffer holes 22b designed on the outer annular surface of the support ring 223 near the microphone body 10's sound-receiving hole 10a, when the wind shield 30 is attached to the right-angled stepped structure 22d via connectors such as the elastic collar, the connectors such as the elastic collar will not obstruct the buffer holes 22b. This ensures that the multiple buffer holes 22b designed on the outer annular surface of the support ring 223 near the microphone body 10's sound-receiving hole 10a can effectively decompress the compressed sound waves after reflection. Regarding the multiple elongated holes extending from the end of the self-supporting ring 223 near the microphone body 10's receiving hole 10a to the end face of the guide ring 221 facing away from the microphone body 10's receiving hole 10a, when the windshield 30 is attached to the right-angled step structure 22d by a connector 40 such as an elastic collar, the connector 40 will not completely block the elongated holes. This ensures that the multiple elongated holes extending from the end of the self-supporting ring 223 near the microphone body 10's receiving hole 10a to the end face of the guide ring 221 facing away from the microphone body 10's receiving hole 10a can effectively decompress the sound waves that have been compressed after reflection.

[0221] By designing the end face of the guide ring 221 facing the microphone body 10's sound-receiving hole 10a and the outer annular surface of the support ring 223 to be perpendicular to each other and form a right-angled step structure 22d, when the windproof cover 30 is hung on the right-angled step structure 22d by the connector 40, the step surface of the right-angled step structure 22d can limit the connector 40, so as to ensure the effectiveness of the connection between the connector 40 and the annular guide seat 22, and effectively reduce or even avoid the possibility of the windproof cover 30 falling off.

[0222] It is worth mentioning that, regarding the CNC milling method for forming the buffer hole 22b, the base 21 and the annular guide seat 22 can be integrally molded from rigid plastic via injection molding. On the one hand, the high machining precision of the CNC milling machine facilitates better control of the size of the buffer hole 22b during processing; on the other hand, the radio guiding mechanism 20, made entirely of rigid plastic, can maximize the structural strength of the large-diameter buffer hole 22b after molding, preventing the guide ring 221 from collapsing or the windproof cover 30 from falling off, which is easily caused by the large-diameter buffer hole 22b. Regarding the punching method for forming the buffer hole 22b, the base 21 and the annular guide seat 22 can be integrally molded from silicone via injection molding. On the one hand, this can maintain the original shape of the radio guiding mechanism 20 as much as possible, making it easier to control its structural dimensions and stability, and reducing processing difficulty; on the other hand, because the buffer hole 22b is formed by punching, the processing area of ​​the radio guiding mechanism 20 is small, and the radio guiding mechanism 20, made entirely of silicone, can utilize shock absorption to reduce the sound wave reflection frequency, thereby reducing the degree of sound distortion.

[0223] As shown in Figures 22 and 24, the microphone body 10 includes multiple microphone cores 50, multiple sound receiving holes 10a, and multiple through holes 21a, with each through hole 21a corresponding to one sound receiving hole 10a and each sound receiving hole 10a corresponding to one microphone core 50. The sound receiving guiding mechanism 20 also includes a barrier 23 connected to at least one of the base 21 and the annular guide seat 22. The barrier 23 is at least partially located within the sound receiving channel 22a of the annular guide seat 22 to divide the sound receiving channel 22a of the annular guide seat 22 into multiple sound receiving chambers, with each sound receiving chamber corresponding to one through hole 21a.

[0224] Among them, the barrier 23, the base 21 and the annular guide seat 22 are integrally formed by injection molding. The overall structure after injection molding can be formed by, but is not limited to, the support column 222 or the buffer hole 22b by means of CNC milling machine (also known as CNC (Computer Numerical Control) milling machine) or stamping machine.

[0225] It is worth mentioning that, for the solution of forming the buffer hole 22b by CNC milling, the barrier 23, the base 21 and the annular guide seat 22 can be integrally formed from hard plastic by injection molding. On the one hand, the high machining accuracy of the CNC milling machine is conducive to better control of the size of the buffer hole 22b during the machining process; on the other hand, the radio guide mechanism 20, which is made of hard plastic as a whole, can support the structural strength of the large-diameter buffer hole 22b after molding to the greatest extent, so as to prevent the guide ring 221 from collapsing or the windproof cover 30 from falling off, which is easily caused by the large-diameter buffer hole 22b. Regarding the solution of punching the buffer hole 22b using a stamping machine, the barrier 23, the base 21, and the annular guide seat 22 can be integrally molded from silicone by injection molding. On the one hand, this can maintain the original shape of the radio guiding mechanism 20 as much as possible, making it easier to control its structural dimensions and stability, and reducing processing difficulty. On the other hand, since the buffer hole 22b is formed by punching, the processing area of ​​the radio guiding mechanism 20 is small, and the radio guiding mechanism 20, which is made entirely of silicone, can use shock absorption and buffering to reduce the reflection frequency of sound waves, thereby reducing the degree of sound degradation.

[0226] As shown in Figure 24, the microphone body 10 has a fixing hole (not shown in the figure), and the sound receiving guide mechanism 20 also includes a fastener 24. The base 21 is connected to the fixing hole through the fastener 24 to achieve a detachable connection with the microphone body 10.

[0227] The fixing hole is a part on the microphone body 10 that cooperates with the fastener 24 to fix the position of the microphone body 10 and the sound receiving guide mechanism 20. The fastener 24 is a component that cooperates with the fixing hole to fix the position of the sound receiving guide mechanism 20 and the microphone body 10. Depending on the specific form of the fixing hole, the corresponding fastener 24 will also have different forms. For example, when the fixing hole is a threaded hole formed on the microphone body 10 (not shown in the figure), the fastener 24 includes a screw (not shown in the figure), and the sound guide mechanism 20 and the microphone body 10 are fixed in position by locking the screw. As another example, as shown in Figure 4, when the fixing hole is a snap hole formed on the microphone body 10 (not shown in the figure), the fastener 24 includes a snap-fit, and the sound guide mechanism 20 and the microphone body 10 are fixed in position by snap-fit ​​engagement. As yet another example, when the fixing hole is a plug hole formed on the microphone body 10 (not shown in the figure), the fastener 24 includes a pin (not shown in the figure), and the sound guide mechanism 20 and the microphone body 10 are fixed in position by pin engagement.

[0228] By designing fastener 24, which cooperates with fixing hole to achieve relative fixation between the position of the sound guide mechanism 20 and the microphone body 10, it is easy to install and disassemble the sound guide mechanism.

[0229] This application provides a microphone 1; the microphone 1 includes a microphone body 10 and the aforementioned sound receiving guide mechanism 20. The microphone body 10 has a sound receiving hole 10a, and the base 21 is connected to the microphone body 10 corresponding to the sound receiving hole 10a.

[0230] The microphone 1 based on the embodiments of this application has the above-described sound receiving guide mechanism 20, which can improve the consistency between the sound quality of the sound wave guided to the sound receiving hole 10a of the microphone body 10 after passing through the sound receiving channel 22a of the annular guide seat 22 and the sound quality of the original sound wave, thereby effectively reducing the degree of sound degradation.
