Description

A wireless microphone

[0001] The present application is based on a Chinese patent application, the corresponding application number is 2024216792438, the application date is July 15, 2024, and the application name is "A wireless microphone". The present application claims priority to the above-mentioned Chinese patent application, and the entire contents of the above-mentioned Chinese patent application are hereby incorporated by reference into the present application. TECHNICAL FIELD

[0002] The present application relates to the technical field of microphones, in particular to a wireless microphone. BACKGROUND

[0003] With the rise of self-media, more and more people are making short videos, short dramas or interviews for shooting. In order to facilitate shooting and sound collection, people usually wear wireless microphones and hold the wireless microphones on the collar to make the wireless microphones close to the sound source. However, the wearing effect of the wireless microphone in the related art is poor and the sound collection effect is poor, which affects the user experience.

[0004] SUMMARY

[0005] The present application provides a wireless microphone that can improve the wearing effect and sound collection effect of the wireless microphone, thereby improving the user experience.

[0006] The technical solution adopted by the present application is as follows:

[0007] The present application discloses a wireless microphone, which comprises a sound collection assembly for collecting audio signals, a microphone main body for processing the collected audio signals, and a connecting piece connecting the sound collection assembly and the microphone main body. The connecting piece cooperates with the microphone main body to form an openable and closable clamping space. The connecting piece has an inner concave surface communicating with the clamping space. In the direction along the bottom end of the microphone main body pointing to the top end of the microphone main body, at least part of the inner concave surface exceeds the microphone main body, and the inner concave surface is between the microphone main body and the sound collection assembly. The size of the sound collection assembly is smaller than the size of the microphone main body.

[0008] The wireless microphone provided by the present application has the following beneficial effects:

[0009] The wireless microphone provided in the application splits the sound receiving assembly and the microphone main body, and connects the split sound receiving assembly and the microphone main body through the connecting piece. At the same time, since the inner concave surface of the connecting piece forming the clamping space at least partially exceeds the microphone main body, the microphone main body can be completely hidden behind the clamping object such as the collar or the brim of the user after the wireless microphone is clamped and worn, and only part of the connecting piece and the sound receiving assembly are exposed in front of the collar or the brim of the user. In this way, the originally integral wireless microphone is split into two parts with different sizes, that is, the sound receiving assembly with a smaller size compared with the microphone main body and the microphone main body, and the inner concave surface of the connecting piece is used to realize the reverse hidden wearing of the microphone main body with a larger size hidden behind the clamping object, so as to reduce the exposed area of the wireless microphone and improve the wearing aesthetics of the wireless microphone. At the same time, the sound receiving assembly with a smaller size is exposed in front of the clamping object to avoid the sound receiving assembly being blocked, so as to improve the sound receiving effect of the wireless microphone. Therefore, the wireless microphone of the application has wearing aesthetics and good sound receiving effect, and can improve the user experience.

[0010] In addition, in the application, the microphone main body can be supported by the body of the user after being hidden behind the clamping object, so as to avoid the problem of wearing the collar in the related art caused by the excessive weight of the microphone main body exposed in front of the clamping object, and further improve the wearing aesthetics and wearing comfort of the wireless microphone, and improve the user experience.

DETAILED DESCRIPTION

[0024] The technical solutions in the present application will be described clearly and completely below in combination with the drawings in the present application. It should be understood that the drawings in the present application are only used for illustrative description, and the omission of some well-known structures and their descriptions in the drawings is understandable for those skilled in the art. Meanwhile, in the description of the present application, if there are descriptions of directions or positional relationships such as "upper", "lower", "left", "right" and the like, they are only based on the directions or positional relationships shown in the drawings for the convenience of the simplified description of the present application, and do not indicate or imply that the indicated devices or elements must have a specific direction, be constructed and operated in a specific direction. Accordingly, the description of the present application involves "first", "second" and the like, which is only used to distinguish different components, and cannot be understood as indicating or implying its relative importance, any order or implicitly indicating the number of indicated technical features.

[0025] With the rise of self-media, more and more people shoot short videos, short dramas or interviews. In order to facilitate shooting and sound collection, people usually wear a wireless microphone and hold the wireless microphone on the collar so that the wireless microphone is close to the sound source to meet the sound collection demand. However, in the related technology, the sound pickup module of the wireless microphone is arranged in an integrated structure with the microphone main body, and the sound pickup module is usually arranged on the outer surface of the microphone main body. In this way, when people wear the wireless microphone to collect sound during video shooting, the microphone main body needs to be completely exposed so that the sound pickup module is in a suitable sound collection position to meet the sound collection demand. However, due to the large size of the microphone main body and the trademark pattern on most microphone main bodies, the wireless microphone occupies the shot due to the large size, and the eye-catching trademark pattern is also conspicuous, which affects the shooting quality and causes the audience to be disgusted. In some official recordings or short dramas and short videos with requirements, this is difficult to accept. If the user wants to avoid the large size of the microphone main body from occupying the shot when wearing the wireless microphone, the microphone main body can only be covered and worn, but in this way, the sound pickup module on the microphone main body is also covered, which affects the sound collection effect. Therefore, the wireless microphone in the related technology has poor wearing effect and poor sound collection effect, resulting in poor user experience.

[0026] Therefore, the wireless microphone 1 provided by the present application can improve the sound collection effect of the wireless microphone 1 while realizing hidden wearing of the wireless microphone 1, thereby improving the user experience and improving the user satisfaction.

[0027] The wireless microphone 1 provided by the present application will be described below in conjunction with the drawings of the specification.

[0028] Referring to FIGS. 1-3, the present application provides a wireless microphone 1, which includes a sound collection assembly 10 for collecting audio signals, a microphone main body 20 for processing the collected audio signals, and a connecting piece 30 connecting the sound collection assembly 10 and the microphone main body 20.

[0029] The connecting piece 30 cooperates with the microphone main body 20 to form an openable and closable clamping space 40, and the connecting piece 30 has an inner concave surface 31 communicating with the clamping space 40. The microphone main body 20 has a top end 20a and a bottom end 20b arranged oppositely. In the direction along the bottom end 20b of the microphone main body 20 to the top end 20a of the microphone main body 20, at least part of the inner concave surface 31 exceeds the microphone main body 20, and the inner concave surface 31 is between the microphone main body 20 and the sound collection assembly 10. The size of the sound collection assembly 10 is smaller than the size of the microphone main body 20.

[0030] It should be noted that the microphone body 20 has a top end 20a and a bottom end 20b which are spaced apart along the X direction in the figure. The connecting member 30 can be connected to the top end 20a of the microphone body 20 or any position of the microphone body 20. The microphone body 20 can be provided in any shape such as a circle, a rectangle or a polygon, as long as the requirement of being worn by the user is met, and the present application does not make any limitation.

[0031] The present application splits the sound receiving assembly 10 and the microphone body 20, and connects the sound receiving assembly 10 and the microphone body 20 through the connecting member 30. The connecting member 30 can be provided in any shape such as a sheet, a strip or a rod, and the present application does not make any limitation. The connecting member 30 can be hinged to the microphone body 20, and the connecting member 30 can have a portion extending along the X direction, so that the connecting member 30 can rotate relative to the microphone body 20 to form a clamping space 40 spaced apart from the microphone body 20 along the Y direction. The clamping space 40 can be used to accommodate any clamping object 60 such as a collar, a hat brim or hair of the user, so as to fix the wireless microphone 1. In some embodiments, a spring or a spring sheet or other elastic reset member can be further provided between the connecting member 30 and the microphone body 20, so as to facilitate the opening and closing of the clamping space 40.

[0032] Meanwhile, the connecting member 30 has an inner concave surface 31 which communicates with the clamping space 40. The inner concave surface 31 can be recessed in the connecting member 30 in a direction from the inside of the clamping space 40 to the outside of the clamping space 40. When the connecting member 30 is connected to the microphone body 20, the inner concave surface 31 is arranged beyond the edge of the microphone body 20. As an example, the inner concave surface 31 is higher than the top end 20a edge of the microphone body 20 along the X direction. In this way, when the user wears the wireless microphone 1, the wearing mode shown in FIGS. 4 and 5 can be formed. In the wearing mode shown in FIGS. 4 and 5, since the inner concave surface 31 at least partially extends beyond the microphone body 20 in a direction from the bottom end 20b of the microphone body 20 to the top end 20a of the microphone body 20, after the wireless microphone 1 is worn, the microphone body 20 can be completely hidden behind the clamping object 60 such as a collar or a hat brim of the user, and only part of the connecting member 30 leaks out in front of the collar or the hat brim of the user, and the size of the outer leakage of the connecting member 30 is obviously smaller than the size of the hidden microphone body 20. Thus, through this reverse wearing mode of hiding the microphone body 20 behind the clamping object 60, the size of the wireless microphone 1 exposed in the lens picture can be significantly reduced, the hidden wearing of the wireless microphone 1 is realized, and the appearance of being on camera is improved.

[0033] Furthermore, to improve the sound pickup effect of the wireless microphone 1, this application separately positions the sound pickup component 10, which is detached from the microphone body 20, on the exposed portion of the connector 30. That is, the sound pickup component 10 can be connected to any position on the connector 30, as long as the sound pickup hole of the sound pickup component 10 is not obstructed when the wireless microphone 1 is worn. As an example, the sound pickup component 10 is positioned on the connector 30 with its concave surface 31 located between the microphone body 20 and the sound pickup component 10. This allows the sound pickup component 10 to protrude from the clamping object 60 and avoid being obstructed, thereby enabling clear sound pickup during recording.

[0034] Furthermore, the size of the sound receiving component 10 is also set to be smaller than the size of the microphone body 20. This smaller size of the sound receiving component 10 compared to the microphone body 20 can include at least one of volumetric size or area size. As an example, the size of the sound receiving component 10 may be smaller than the size of the microphone body 20 in any direction, such as the thickness direction, length direction, or width direction of the microphone body 20 (e.g., as shown in the X, Y, and Z directions in the figure). Thus, even if the sound receiving component 10 is exposed when the wireless microphone 1 is worn, the exposed size of the sound receiving component 10 is relatively smaller than the exposed size of the microphone body 20 in related technologies. Therefore, the overall size of the exposed portion of the wireless microphone 1 after wearing is relatively smaller than the size of the hidden portion of the microphone body 20, thereby reducing the exposed area of ​​the wireless microphone 1 after wearing.

[0035] Therefore, compared to related technologies, the wireless microphone 1 provided in this application separates the sound receiving component 10 from the microphone body 20, and the size of the separated sound receiving component 10 is smaller than the size of the microphone body 20. The separated sound receiving component 10 is connected to the microphone body 20 via a connector 30. Since the concave surface 31 of the connector 30 forming the clamping space 40 extends at least partially beyond the microphone body 20, the microphone body 20 can be completely hidden behind the user's collar or hat brim after the wireless microphone 1 is clamped and worn, while only part of the connector 30 and the sound receiving component 10 are exposed in front of the user's collar or hat brim. In this way, the originally integral wireless microphone 1 is split into two parts of different sizes, and the concave surface 31 of the connector 30 is used to achieve reverse concealment wearing by hiding the larger microphone body 20 behind the clamp 60, reducing the exposed area of ​​the wireless microphone 1 and improving the wearing aesthetics of the wireless microphone 1. Meanwhile, the smaller microphone component 10 is protruded from the front of the clamp 60 to prevent it from being obstructed, thereby improving the sound pickup effect of the wireless microphone 1. Thus, the wireless microphone 1 of this application combines aesthetic appeal with excellent sound pickup, enhancing the user experience.

[0036] Furthermore, in the wearing methods shown in Figures 4 and 5, the microphone body 20 can be supported by the user's body after being hidden in the clamp 60, so as to avoid the problem of the microphone body 20 being exposed in front of the clamp 60 due to excessive weight and causing the collar to turn up when wearing it, which is a problem in the related technology. This further improves the aesthetics and wearing comfort of the wireless microphone 1.

[0037] Referring to Figure 6, in some embodiments, to improve the wearing effect of the wireless microphone 1, the microphone body 20 has a clamping surface 21 forming a clamping space 40 and an outer surface 22 disposed opposite to the clamping surface 21. In the direction from the outer surface 22 of the microphone body 20 to the clamping surface 21, the microphone body 20 and the sound receiving component 10 at least partially overlap. The sound receiving component 10, the connector 30 and the microphone body 20 cooperate to form the clamping space 40.

[0038] It should be noted that the microphone body 20 and the sound-receiving component 10 can be respectively disposed at both ends of the connector 30. As an example, the connector 30 can be configured as a U-shape or other arc shape, so that the microphone body 20 and the sound-receiving component 10 can be disposed opposite to each other along the Y direction. In this way, the connector 30 can be used to connect the split microphone body 20 and the sound-receiving component 10, and the exposed sound-receiving component 10 can work together with the connector 30 to clamp the collar or brim of a hat or other object 60, thereby increasing the clamping area of ​​the object 60 and improving the wearing stability of the wireless microphone 1. Optionally, the center position of the microphone body 20 and the center position of the sound-receiving component 10 are respectively disposed on opposite sides of the clamped position of the object 60, so as to improve the clamping effect of the object 60. Of course, in other embodiments, the sound-receiving component 10 can also be disposed at other positions of the connector 30, as long as the sound-receiving component 10 is not obstructed and affects the sound reception effect after the wireless microphone 1 is worn.

[0039] In some embodiments, to facilitate the connection of the connector 30 to the microphone body 20 and the microphone receiving assembly 10, the connector 30 includes a main body connecting portion 33 and a microphone receiving connecting portion 32. The main body connecting portion 33 is connected to the microphone body 20. The microphone receiving connecting portion 32 is connected between the main body connecting portion 33 and the microphone receiving assembly 10.

[0040] It should be noted that the main body connecting part 33 and the radio connecting part 32 of the connector 30 can be disassembled and assembled for easy replacement and production. At the same time, in order to improve the smoothness and aesthetics of the connector 30, the main body connecting part 33 and the radio connecting part 32 can also be set as an integrally molded structure, and this application does not impose any restrictions.

[0041] The main body connecting part 33 and the microphone body 20 can be connected by various methods such as magnetic attraction, plug-in connection, threaded connection, adhesive fixation or welding fixation, and this application does not impose any restrictions. The microphone connecting part 32 and the microphone assembly 10 can also be connected by various methods such as magnetic attraction, plug-in connection, threaded connection, adhesive fixation or welding fixation, and this application does not impose any restrictions.

[0042] In some embodiments, to improve the connection stability between the connector 30 and the microphone body 20, the cross-sectional area of ​​the main body connecting portion 33 gradually increases in the direction from the top end 20a to the bottom end 20b of the microphone body 20. As an example, the outer wall of the main body connecting portion 33 connected to the microphone body 20 gradually expands outward to increase the connection area between the connector 30 and the microphone body 20, thereby improving the connection stability between the connector 30 and the microphone body 20. Simultaneously, the smooth lines of the outer surface 34 of the main body connecting portion 33 also enhance aesthetics.

[0043] In some embodiments, to improve the connection stability between the connector 30 and the microphone assembly 20, the cross-sectional area of ​​the microphone connection portion 32 gradually increases in the direction from the top end 20a to the bottom end 20b of the microphone body 20. As an example, the outer wall of the portion of the microphone connection portion 32 that connects to the microphone assembly 10 gradually expands outward to increase the connection area between the connector 30 and the microphone assembly 10, thereby improving the connection stability between them. Simultaneously, the smooth lines of the outer surface 34 of the microphone connection portion 32 also enhance its aesthetics.

[0044] In some embodiments, to facilitate the formation of the concave surface 31, the concave surface 31 is disposed in at least one of the main body connecting portion 33 and the radio receiving connecting portion 32. Alternatively, the connector 30 further includes a transition connecting portion connecting the main body connecting portion 33 and the radio receiving connecting portion 32, and the concave surface 31 is disposed in the transition connecting portion.

[0045] It should be noted that the main connecting portion 33 and the receiver connecting portion 32 can be connected to form a corner, and the concave surface 31 is provided at the corner, which can be formed by a part of the main connecting portion 33 and a part of the receiver connecting portion 32. Alternatively, the main connecting portion 33 and the receiver connecting portion 32 extend in different directions, and the concave surface 31 can be provided in either the main connecting portion 33 or the receiver connecting portion 32; this application does not impose any limitation. Alternatively, the connector 30 may also include a transition connecting portion connecting the main connecting portion 33 and the receiver connecting portion 32, and the concave surface 31 is provided in the transition connecting portion. As an example, the transition connecting portion is set as a U-shaped structure, with the main connecting portion 33 and the receiver connecting portion 32 arranged opposite to each other and respectively connected to both ends of the U-shaped structure.

[0046] In some embodiments, to facilitate wearing the wireless microphone 1, the concave surface 31 extends in an arc shape along the direction from the outer side 22 of the microphone body 20 toward the clamping surface 21. This configuration allows the inner wall of the clamping space 40 to form a smooth line, thereby preventing the clamping object 60 from being pulled during the wearing of the wireless microphone 1, thus facilitating the wearing of the wireless microphone 1.

[0047] In some embodiments, to improve the aesthetics of the wireless microphone 1, the connector 30 has an outer surface 34 opposite to the concave surface 31, and the outer surface 34 of the connector 30 smoothly transitions from the main body connecting portion 33 to the sound receiving connecting portion 32. This design ensures that the exposed portion of the connector 30 after the wireless microphone 1 is worn has a smooth, arc-shaped transition, resulting in a streamlined overall appearance and enhanced aesthetics. Simultaneously, this design also prevents sharp corners from forming on the outer wall of the connector 30, reducing the risk of damage to the wireless microphone 1 from impacts and preventing injury to the user.

[0048] Referring to Figures 6 and 7, in some embodiments, the microphone assembly 10 includes a microphone housing 11 and an audio acquisition element 12 mounted on the microphone housing 11, the audio acquisition element 12 being used to acquire audio signals. The microphone body 20 includes a microphone housing 23 and a processing element 24 mounted on the microphone housing 23, the processing element 24 being used to process the acquired audio signals. The microphone housing 11 and the microphone housing 23 are respectively connected to the connector 30.

[0049] The audio acquisition element 12 includes a diaphragm device. The processing element 24 includes a main circuit board. The processing element 24 and the audio acquisition element 12 can be connected via various short-range communication methods such as Bluetooth, NFC, or Wi-Fi. This application does not impose any limitations.

[0050] In some embodiments, the processing element 24 and the audio acquisition element 12 can also be connected by a wire. The wireless microphone may include a connecting wire 38 disposed within and extending along the connector 30, one end of the connecting wire 38 passing through the microphone housing 11 and connected to the audio acquisition element 12, and the other end of the connecting wire 38 passing through the microphone housing 23 and connected to the processing element 24.

[0051] This configuration allows for the mechanical connection between the microphone housing 23 and the receiver housing 11 via the connector 30, while also enabling the circuit connection between the processing element 24 and the audio acquisition element 12 via the built-in connecting wire 38 in the connector 30. This not only makes the assembly of the wireless microphone 1 convenient and efficient, but also makes the appearance of the wireless microphone 1 more concise due to the built-in connecting wire 38.

[0052] As an example, to simultaneously meet the installation requirements of the connector 30 and the connecting wire 38, the microphone housing 11 is provided with a microphone connection hole 15. One end of the connector 30 is connected to the microphone connection hole 15, and one end of the connecting wire 38 passes through the microphone connection hole 15 and is connected to the audio acquisition element 12. Correspondingly, the microphone housing 23 is provided with a main body connection hole 25. The other end of the connector 30 is connected to the main body connection hole 25, and the other end of the connecting wire 38 can also enter the microphone housing 23 through the main body connection hole 25 to connect to the processing element 24.

[0053] In some embodiments, since the microphone assembly 10 may contain some electronic components or other structures to collect audio signals or other desired signals, and the microphone body 20 may contain some electronic components or other structures to transmit or process the collected audio signals or other signals, when the microphone housing 11 and the microphone housing 23 are respectively provided with connection holes to cooperate with the connector 30 or the connecting wire 38 for connection, it is also necessary to perform sealing treatment between the connector 30 and the microphone housing 11 microphone connection hole 15, and between the connector 30 and the microphone housing 23 body connection hole 25. Optionally, the sealing treatment can be performed by setting a sealing ring, gluing, welding, threaded fit or interference fit, etc., and this application does not limit it.

[0054] Referring to Figures 6 and 7, in some embodiments, the wireless microphone may also include a limiting member 35 to position the connecting wire 38 to ensure reliable connection between the connecting wire 38 and the audio acquisition element 12 and the processing element 24.

[0055] The connector 30 is connected to the receiver connection hole 15 at one end, serving as the receiver connection end, and to the main body connection hole 25 at the other end, serving as the main body connection end. Two limiting members 35 may be provided. The first limiting member 35 is connected between the receiver connection end of the connector 30 and the connecting wire 38, and is inserted into the receiver connection hole 15 for fixation. The second limiting member 35 is connected between the main body connection end of the connector 30 and the connecting wire 38, and is inserted into the main body connection hole 25 for fixation.

[0056] As an example, the limiting member 35 can be configured as a latch structure with a through hole. Specifically, the limiting member 35 connected to the radio connection hole 15 is configured as a radio latch 35a, and the limiting member 35 connected to the main body connection hole 25 is configured as a main body latch 35b.

[0057] The receiver latch 35a is fixed to the receiver connection end of the connector 30, and the connecting wire 38 is fixed inside the through hole of the receiver latch 35a, with a portion of the connecting wire 38 extending through the through hole of the receiver latch 35a as a receiver terminal. The main body latch 35b is fixed to the main body connection end of the connector 30, and the connecting wire 38 is fixed inside the through hole of the main body latch 35b, with a portion of the connecting wire 38 extending through the through hole of the main body latch 35b as a main body terminal.

[0058] When assembling the connector 30 and the microphone assembly 10, the microphone latch 35a can be directly inserted into the microphone connection hole 15 of the microphone housing 11. This fixes the connector 30 to the microphone housing 11 and connects the microphone connection end of the connecting wire 38 to the audio acquisition element 12 inside the microphone housing 11, thus simultaneously completing the mechanical connection and the wire connection. When assembling the connector 30 and the microphone body 20, the body latch 35b can be directly inserted into the body connection hole 25 of the microphone housing 23. This fixes the connector 30 to the microphone housing 23 and connects the body connection end of the connecting wire 38 to the processing element 24 inside the microphone housing 23, thus simultaneously completing the mechanical connection and the wire connection.

[0059] Therefore, the limiting member 35 can restrict the relative position between the connector 30 and the connecting wire 38, preventing the connecting wire 38 from moving and causing a loose connection between the processing element 24 and the audio acquisition element 12, thus ensuring the reliability of the wire connection. At the same time, the limiting member 35 can cooperate with the connecting holes on the microphone housing 11 and the microphone housing 23 to complete the mechanical connection and wire connection between the connector and the microphone body and the sound acquisition assembly, thereby simplifying the installation.

[0060] Furthermore, when the connector 30 is connected to the microphone body 20, the limiting member 35 can be inserted and hidden inside the microphone housing 23. When the connector 30 is connected to the sound receiving assembly 10, the limiting member 35 can also be inserted and hidden inside the sound receiving housing 11. This can improve connection reliability while ensuring the appearance of the wireless microphone 1 remains unchanged, and further reduce the size of the wireless microphone 1 that is exposed when worn.

[0061] In some embodiments, the outer wall of each limiting member 35 may be provided with a partially uneven fitting structure. Correspondingly, the inner walls of the receiver connection hole 15 and the main body connection hole 25 may be provided with a fitting and mating structure adapted to the fitting structure. In this way, the fitting structure and the fitting and mating structure can be used to increase the connection area between the limiting member 35 and each connection hole, thereby improving the insertion stability. At the same time, the mutual cooperation between the fitting structure and the fitting and mating structure can also be used to improve the insertion sealing effect. Of course, in some embodiments, the limiting member 35 and each connection hole can also be fixed and sealed by a glue application process, which is not limited in this application.

[0062] Referring again to Figures 6 and 7, in some embodiments, to improve the aesthetics of the wireless microphone 1, the wireless microphone 1 also includes a sheath 39, which covers the connector 30, the connecting wire 38 and the limiting member 35, thereby reducing the cross-section of the wireless microphone 1 and improving the overall aesthetics and the sealing of the connections between the parts.

[0063] Meanwhile, the sheath 39 covering the outer surface 34 of the connector 30 can be made of a soft material, such as silicone or rubber, to increase the friction between the connector 30 and the clamped object 60, thereby improving clamping stability. The soft material also allows for a flexible connection with the clamped object 60, reducing damage to it. In other embodiments, a cavity can be provided inside the connector 30 for the installation of the connecting wire 38 and the limiting member 35. In these embodiments, the outer surface of the connector 30 can also be made of a soft material to function as the sheath 39. This application does not impose any limitations on this aspect.

[0064] Referring to Figures 8 and 9, in some embodiments, the connecting wire 38 can be directly fixed to the connector 30 to eliminate the limiting member 35, thereby reducing the coverage volume of the sheath 39. As an example, the connector 30 can be configured as a sheet or strip, with the connecting wire 38 laid flat and fixed to the wall surface of the connector 30 along its extension direction. The connecting wire 38 can be fixed to the connector 30 by adhesive or other means, which is not limited in this application. Optionally, the connecting wire 38 can be fixed to the inner wall of the connector 30 facing the clamping space 40 for concealed installation.

[0065] As an example, the connector 30 can also be rod-shaped, with the connecting wire 38 wound around its surface for fixation. The connecting wire 38 can be fixed to the connector 30 in various ways, such as clockwise winding, counterclockwise winding, double-strand winding, or cross-winding, and this application does not impose any restrictions. Of course, the connector 30 can also be made into other elongated shapes, as long as it satisfies the installation of the connecting wire 38 and the connection between the microphone body 20 and the sound receiving component 10, and the exposed area of ​​the connector 30 is small when the wireless microphone 1 is worn. This application will not elaborate on other shapes of the connector 30.

[0066] With this configuration, since the limiting member 35 is eliminated, when the sheath 39 is used to cover the connector 30 and the connecting wire 38, it is no longer necessary to cover the limiting member 35, thereby reducing the volume of the molded sheath 39 (e.g., the sheath 39 is narrower in the Z direction in the figure). This reduces the exposed size of the connection between the microphone body 30 and the sound receiving assembly 10, and consequently reduces the exposed size of the wireless microphone 1 after it is worn, improving the concealment effect and aesthetics. As an example, the sheath 39 covers the connector 30 and the connecting wire 38 to form an integral connection structure. This connection structure can be set as a U-shaped piece of uniform thickness or other arc shape.

[0067] Furthermore, since the limiting member 35 is eliminated, the connecting wire 38 and the connector 30 are directly fixed into a whole. Therefore, to prevent the connecting wire 38 from moving and causing a loose connection between the processing element 24 and the audio acquisition element 12, limiting parts 36 can be provided at both ends of the connector 30. After the two ends of the connector 30 are inserted into the receiver housing 11 and the microphone housing 23 respectively, the connecting part 36 is further fixed to the receiver housing 11 and the microphone housing 23 by cooperating with the connecting holes of each housing. This can improve the connection stability between the connector 30 and the microphone housing 23 and the receiver housing 11, and can also position the connecting wire 38 by positioning the connector 30, thereby improving the connection reliability between the connecting wire 38 and the processing element 24 and the audio acquisition element 12. As an example, the outer walls at both ends of the connector 30 can be provided with recesses to form the limiting parts 36.

[0068] In some related technologies, the wireless microphone 1 is fixed by a rigid back clip that opens and closes at a fixed angle with the main body via a spring. This not only places certain requirements on the size of the object being clamped, but also makes the spring of the back clip prone to failure during use. Therefore, referring to Figures 7 to 9, in some embodiments, to enable the wireless microphone 1 to be worn on clamping objects 60 of different sizes, the connector 30 is elastic, and the connector 30 extends in an arc shape in the direction from the microphone body 20 to the sound receiving assembly 10.

[0069] It should be noted that the connector 30 can be a flexible metal spring or a non-metallic spring capable of opening and closing, such as any spring made of iron, aluminum, gold, silver, silicone, or rubber, etc., and this application does not impose any restrictions. The connector 30 can be U-shaped to facilitate the connection between the microphone body 20 and the sound receiving assembly 10, forming a clamping space 40.

[0070] In other embodiments, to extend the service life of the connector 30, the connector 30 is made of shape memory alloy 37, or the connector 30 has a built-in shape memory alloy 37 to form an elastic skeleton using the shape memory alloy 37.

[0071] It should be noted that the shape memory alloy 37 includes alloys such as nickel-titanium alloys, copper-zinc-aluminum alloys, or nickel-titanium-silver alloys, and this application does not impose any restrictions. As long as the shape memory alloy 37 has a memory function and can recover its initial shape at room temperature, exhibiting good resilience, it is acceptable. Thus, by setting the shape memory alloy 37 frame, the initial small angle allows the microphone assembly 10 and microphone body 20 connected to both ends of the connector 30 to fit tightly together. During use, regardless of whether a collar or other thick object 60 is placed in the clamping space 40, the shape memory alloy 37 will generate stress inwards within the clamping space 40, thus clamping and fixing the object 60. Furthermore, regardless of whether excessive deformation occurs during actual use, the shape memory alloy 37 can recover its initial shape at room temperature, eliminating concerns about failure. Therefore, by setting the connector 30 with the shape memory alloy 37, the limitations on the size of the object 60 held by the wireless microphone 1 can be relaxed, and the service life of the connector 30 can be extended.

[0072] In addition, in some embodiments, the outer surface of the connector 30 is made of a soft material, or the outer surface 34 of the connector 30 may be covered with a soft material sheath, such as silicone or rubber, to increase the friction between the connector 30 and the clamped object 60 and improve clamping stability. At the same time, the soft material can achieve a flexible connection with the clamped object 60 to reduce damage to the clamped object 60.

[0073] As an example, to facilitate the connection between the microphone body 20 and the microphone receiver 10, this application provides a connection component. The connection component includes a flexible frame, a connecting wire 38, and a sheath 39. The flexible frame connects the microphone body 20 and the microphone receiver 10, forming a clamping space 40 with the microphone body 20, and the flexible frame has a concave surface 31. Optionally, the flexible frame is made of shape memory alloy 37. The connecting wire 38 is fixed to the flexible frame and extends along the flexible frame, and the connecting wire 38 is used for the electrical connection between the microphone body 20 and the microphone receiver 10 to transmit audio signals. The sheath 39 covers the exterior of the flexible frame and the connecting wire 38, and both ends of the sheath 39 smoothly transition to the microphone body 20 and / or the microphone receiver 10, respectively.

[0074] Among them, the connecting wire 38 and the elastic skeleton made of shape memory alloy 37 are parallel, and both ends of the connecting wire 38 are exposed to a certain length in order to connect the main circuit board of the processing element 24 and the circuit board of the audio acquisition element 12. Finally, the shape memory alloy 37 skeleton and the connecting wire 38 are covered with a layer of soft material through the encapsulation process to form a sheath 39.

[0075] The microphone housing 23 has a through hole, through which one end of the connecting wire 38 extends to the inside of the microphone housing 23 and connects to the processing element 24. Simultaneously, the shape memory alloy 37 frame is inserted and fixed into the through hole. The receiver housing 11 also has a through hole, through which the other end of the connecting wire 38 extends to the inside of the receiver housing 11 and connects to the audio acquisition element 12. Simultaneously, the shape memory alloy 37 frame is inserted and fixed into the through hole. Thus, the mechanical connection and wire connection between the microphone body 20 and the receiver assembly 10 are completed through the connector 30.

[0076] Referring to Figure 10, in some embodiments, the microphone assembly 10 includes a microphone housing 11 and an audio acquisition element 12 mounted on the microphone housing 11. The audio acquisition element 12 is used to acquire audio signals. The audio acquisition element 12 includes a diaphragm device. A plurality of microphone holes 13 may be provided on the microphone housing 11, with each microphone hole 13 corresponding to a diaphragm device to improve the microphone reception. The microphone holes 13 can be various shapes such as strip holes, round holes, or square holes; this application does not limit the shapes. Furthermore, the microphone housing 11 is also provided with windproof holes 14 spaced apart from the microphone holes 13, so that a windproof sweater can be installed through the windproof holes 14 to prevent popping sounds and enable the wireless microphone 1 to perform microphone reception in windy weather.

[0077] In some embodiments, to facilitate the assembly of the receiver housing 11 and the audio acquisition element 12, the receiver housing 11 may be formed by splicing at least two half-housing halves, forming a cavity in which the audio acquisition element 12 is fixed to protect it. As an example, the receiver housing 11 includes an upper housing and a lower housing, at least one of which is provided with a sound-receiving hole 13. It is understood that the fixing methods of the connector 30 to the microphone body 20 and the receiver assembly 10 include, but are not limited to, effective locking methods such as split-locking fixing and through-hole glue fixing; this application does not limit these methods.

[0078] In some embodiments, to facilitate the formation of a radio connection hole 15 on the radio housing 11, the upper and lower housings of the radio housing may each be provided with two semi-circular notches to be spliced ​​together to form a radio connection hole 15, so that one end of the connector 30 can be inserted into the radio connection hole 15 for fixation, and the connecting wire 38 can also enter the radio housing 11 through the radio connection hole 15 to be connected to the audio acquisition element 12.

[0079] Referring to Figure 11, the microphone body 20 includes a microphone housing 23 and a processing element 24. The processing element 24 includes components such as a main circuit board and an antenna. The microphone housing 23 has a main body connection hole 25 to facilitate the connection of the connector 30. At the same time, the microphone housing 23 has an indicator light to indicate whether the microphone body 20 is in working or standby mode, or to indicate the battery status of the microphone body 20.

[0080] Referring back to Figure 6, in some embodiments, to improve the connection stability between the connector 30 and the microphone housing 23 and the receiver housing 11, the connector 30 includes a receiver connection portion 32 connected to the receiver connection hole 15 and a main body connection portion 33 connected to the main body connection hole 25. Specifically, in the direction from the bottom end 20b of the microphone body 20 to the top end 20a of the microphone housing 23, the receiver connection portion 32 smoothly transitions to the receiver connection hole 15. As an example, the outer walls of the receiver connection portion 32 and the receiver connection hole 15 gradually widen outward to increase the connection area between the connector 30 and the receiver assembly 10, thereby improving the connection stability between the connector 30 and the receiver assembly 10. Simultaneously, the smooth lines of the outer surface 34 of the receiver connection portion 32 and the receiver connection hole 15 also enhance aesthetics. Correspondingly, in the direction from the bottom end 20b of the microphone body 20 to the top end 20a of the microphone housing 23, the main body connection portion 33 smoothly transitions to the main body connection hole 25. As an example, the outer walls of the main body connecting portion 33 and the main body connecting hole 25 gradually expand outward to increase the connection area between the connector 30 and the microphone body 20, thereby improving the connection stability between the connector 30 and the microphone body 20. At the same time, the smooth lines of the outer surface 34 of the main body connecting portion 33 and the main body connecting hole 25 also enhance the aesthetics.

[0081] Referring to Figure 6, in some embodiments, to improve the wearing stability of the wireless microphone 1, the wireless microphone 1 includes a positioning component 50, which includes a positioning member 51 and a positioning mating member 52. The positioning member 51 is disposed on the clamping surface 21 of the microphone body 20. The positioning mating member 52 is disposed on the side of the sound receiving component 10 opposite to the clamping surface 21 of the microphone body 20. The positioning member 51 and the positioning mating member 52 are detachably connected.

[0082] It should be noted that the positioning component 51 can be disposed on the clamping surface 21 of the microphone housing 23, and the positioning mating component 52 can be disposed on the side of the receiver housing 11 opposite to the clamping surface 21 of the microphone housing 23. In this way, the positioning component 50 can further improve the clamping force on the object 60 in the clamping space 40, thereby enhancing the clamping effect on the object 60, improving the wearing stability of the wireless microphone 1, and preventing it from falling off.

[0083] As an example, the positioning member 51 and the positioning mating member 52 can be configured as magnetic assemblies that can attract each other. This allows for easy assembly and disassembly of the magnetic assembly, and the magnetic assembly can also be configured as a planar structure to reduce damage to the clamped object 60. Of course, in other embodiments, the positioning member 51 and the positioning mating member 52 can be configured as a plug-in fit; this application does not impose any limitations.

[0084]

[0001] In some embodiments, to further improve the wearing stability of the wireless microphone 1, the wireless microphone 1 also includes an anti-slip component disposed on the inner wall of the clamping space 40. It should be noted that the anti-slip component can be configured as several protruding structures extending from the inner wall of the clamping space 40 to increase the friction between the clamped object 60 and the inner wall of the clamping space 40, thereby restricting the movement of the clamped object 60 in various directions of the clamping space 40 (such as along the height direction, width direction, etc. of the microphone body 20), and thus improving the wearing stability of the wireless microphone 1. Of course, the anti-slip component can also be a silicone structure, which increases the friction between the clamped object 60 and the inner wall of the clamping space 40 by roughening the inner wall of the clamping space 40, thereby limiting the position of the clamped object 60. This application does not limit the structure of the anti-slip component. Other structures of the wireless microphone 1 are not described in detail in this application.
