Description

Technical Field

[0001] This application relates to the field of microphone technology, and in particular to a sound-guiding mechanism and a microphone. Background Technology

[0002] The microphone includes a microphone body, a sound guide mechanism, and a windscreen; the microphone body has a sound-receiving hole; the sound guide mechanism is connected to the microphone body corresponding to the sound-receiving hole, and the sound guide mechanism forms a sound-receiving channel; the windscreen is used to prevent popping sounds and is connected to the sound guide mechanism.

[0003] Sound waves enter the sound-receiving channel of the microphone's pickup guide mechanism from the windshield. Understandably, upon entering this channel, some sound waves inevitably collide with the inner surface of the mechanism and are reflected. The propagation path of the reflected sound waves interferes with the propagation path of the unreflected sound waves, affecting their amplitude and frequency. This results in a difference in sound quality between the sound waves guided through the pickup channel and the microphone's aperture and the original sound waves (i.e., the sound waves before entering the pickup channel), leading to sound degradation. Therefore, improving microphone pickup performance to enhance sound quality consistency has become a pressing issue. Utility Model Content

[0004] This application provides a sound reception guidance mechanism and a microphone, which can solve the problem of poor sound quality consistency caused by poor sound reception in related technologies.

[0005] In a first aspect, embodiments of this application provide a sound-guiding mechanism; the sound-guiding mechanism is applied to a microphone, the microphone including a microphone body having a sound-receiving hole, the sound-guiding mechanism including a base and an annular guide seat, the base having a through hole corresponding to the sound-receiving hole of the microphone body, and the base being used to connect to the microphone body, the annular guide seat being connected to the side of the base away from the sound-receiving hole of the microphone body, the area formed by the inner side of the annular guide seat serving as a sound-receiving channel, and the outer side of the annular guide seat having a buffer hole communicating with the sound-receiving channel.

[0006] Based on the sound-guiding mechanism of this application embodiment, when sound waves enter the sound-receiving channel of the annular guide seat, a buffer hole communicating with the sound-receiving channel is designed on the outer side of the annular guide seat. This allows the sound waves, compressed after reflection from the inner side of the annular guide seat, to be decompressed through the buffer hole. This improves the consistency between the sound quality of the sound waves guided to the microphone's receiving port after passing through the annular guide seat's sound-receiving channel and the original sound wave, effectively reducing the degree of sound degradation. Furthermore, due to the presence of the buffer hole, the probability of sound waves entering the annular guide seat's sound-receiving channel contacting the inner side of the annular guide seat is significantly reduced. Therefore, the probability of sound wave reflection decreases, further reducing the probability of sound wave amplitude and frequency disturbances, which also reduces the degree of sound degradation.

[0007] Secondly, this application provides a microphone; the microphone includes a microphone body and the aforementioned sound-receiving guiding mechanism, the microphone body has a sound-receiving hole, and the base is connected to the microphone body corresponding to the sound-receiving hole.

[0008] The microphone based on the embodiments of this application has the above-described sound guidance mechanism, which can improve the consistency between the sound quality of the sound wave guided to the sound hole of the microphone body after passing through the sound channel of the annular guide seat and the sound quality of the original sound wave, thereby effectively reducing the degree of sound degradation.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Please refer to Figures 1-4 As shown, in a first aspect, this application 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.

[0020] 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.

[0021] The following combination Figures 1-7 The specific structure of the sound guiding mechanism 20 will be described in detail below; 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.

[0022] like Figures 1-4 As shown, the radio guiding mechanism 20 includes a base 21 and an annular guide seat 22.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] like Figure 4 As shown, the annular guide seat 22 includes a guide ring 221 and a plurality of support pillars 222; the guide ring 221 defines a central axis; the plurality of support pillars 222 are spaced apart around the central axis of the guide ring 221, with one end of each support pillar 222 near the microphone body 10's sound-receiving hole 10a connected to the base 21, and the other end of each support pillar 222 away from the microphone body 10's sound-receiving hole 10a 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 pillars 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 pillars 222.

[0033] 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.

[0034] 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.

[0035] like Figures 4-5As shown, 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.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, 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 and the outer surface of the support column 222 smoothly transition 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.

[0037] 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.

[0038] 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.

[0039] like Figure 6As shown, 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.

[0040] 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.

[0041] 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.

[0042] like Figure 7 As shown, 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, which extend 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.

[0043] 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.

[0044] 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.

[0045] like Figures 6-7 As shown, 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 to form 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] like Figure 2 and Figure 4 As shown, 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.

[0050] 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.

[0051] 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.

[0052] like Figure 4 As shown, 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.

[0053] The fixing hole is a part on the microphone body 10 that mates with the fastener 24 to fix the relative positions of the microphone body 10 and the sound-guiding mechanism 20. The fastener 24 is a component that mates with the fixing hole to fix the relative positions of the sound-guiding mechanism 20 and the microphone body 10. Depending on the specific form of the fixing hole, the specific form of the fastener 24 that mates with it also varies; 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), in which case the sound-guiding mechanism 20 and the microphone body 10 are fixed in relative position by locking the screw; or, for example, ... Figure 4 As shown, when the fixing hole is a snap-fit ​​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 relative position by snap-fit ​​engagement; for 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 relative position by pin engagement.

[0054] 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.
