Abstract
Description
[Technical Field]
[0001] The present invention relates to a microphone windscreen and a microphone device. [Background technology]
[0002] When a microphone is exposed to wind in an environment in which it is used, the output from the microphone may contain wind noise caused by wind noise, etc. To prevent this wind noise, a windscreen (windbreak) that covers the microphone is attached to the microphone (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-347984
[0004] The windscreen is made of a porous elastic material such as polyurethane and is placed directly over the microphone. The windscreen has a non-through hole at one end (bottom end) into which the microphone is housed. 。 The inner diameter of the insertion hole is smaller than the outer diameter of the microphone. Therefore, when the windscreen is attached to the microphone, it is expanded so that the insertion hole is larger than the diameter of the microphone. At this time, the elastic force of the windscreen tightens the insertion hole around the microphone. As a result, the windscreen is fixed to the microphone by the tightening force on the microphone and the frictional force generated between the windscreen and the microphone (hereinafter collectively referred to as "retention force"). In this way, by covering the microphone with the windscreen, wind noise is prevented from being generated.
[0005] Microphones that can be fitted with windscreens include small microphones such as lavalier microphones and gun microphones. These microphones are used for a wide range of purposes, including recording audio for video recording, voice calls, and lectures. Lavalier microphones, in particular, are worn by the speaker (human body) during television programs and lectures.
[0006] In recent years, microphones with attached windscreens (e.g., lavalier microphones) have been widely used, for example, in sports venues that are broadcast on television (e.g., curling and volleyball). For example, microphones are worn by curling players to monitor the communication between the players during the match. Operation They can pick up sounds such as conversations in meetings, players' sighs and breathing, etc. Furthermore, for example, microphones can be attached to a volleyball net to pick up sounds such as players hitting the ball and players blocking the ball. As a result, television viewers can enjoy watching sports while experiencing the voices of the players and the sounds of the competition, along with a sense of realism and excitement.
[0007] As described above, conventional windscreens are fixed to microphones by their holding force. However, for example, as the windscreen deteriorates over time, the holding force of the windscreen on the microphone decreases. A windscreen with a decreased holding force on the microphone is more likely to fall off the microphone.
[0008] However, if a windscreen falls off a microphone at a sports venue, it not only hinders the progress of the game, but can also cause injuries to athletes due to slipping, etc. In other words, a detached windscreen can be a major obstacle to the game.
[0009] In the field where such microphones are used, adhesives have been used to attach windscreens to microphones to prevent them from falling off. As a result, the windscreen's holding force on the microphone is improved. However, this reduces the ease with which the windscreen can be attached and detached from the microphone. In other words, when adhesives are used, the workability of attaching and detaching the windscreen to the microphone is reduced. Furthermore, once the windscreen is attached, it cannot be removed from the microphone unless it is torn (ruptured). For this reason, windscreens are disposable.
[0010] Furthermore, when adhesive is used, depending on the amount of adhesive applied and the position where the adhesive comes into contact with the microphone, the adhesive may interfere with the sound pickup portion of the microphone, which may degrade the sound quality of the microphone. Summary of the Invention [Problem to be solved by the invention]
[0011] An object of the present invention is to provide a microphone windscreen and a microphone device that can easily attach and detach the windscreen to and from the microphone and can prevent the windscreen from falling off the microphone. [Means for solving the problem]
[0012] The microphone windscreen of the present invention comprises a windscreen main body that is detachably attached to a microphone, and a detachable member that connects to the windscreen main body, wherein the windscreen main body has an insertion hole that is open at one end and into which the microphone is accommodated, and the detachable member has an insertion hole into which the microphone to be accommodated in the insertion hole is inserted, and a claw portion that is configured to be foldable and is placed in the insertion hole, wherein the claw portion is located in an unfolded, fixed position before the microphone is inserted from the insertion hole toward the insertion hole, is bent toward the insertion hole by the microphone while the microphone is being inserted from the insertion hole toward the insertion hole, and returns to its fixed position after the microphone is accommodated in the insertion hole. [Effects of the Invention]
[0013] According to the present invention, it is possible to easily attach and detach the windscreen to and from the microphone, and also to prevent the windscreen from falling off the microphone. [Brief explanation of the drawings]

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a microphone device and a windscreen according to the present invention will be described with reference to the drawings.
[0016] ●Microphone device● Microphone device configuration FIG. 1 is a front view showing an embodiment of a microphone device according to the present invention.
[0017] The microphone device 1 collects sound waves from a sound source (not shown) and outputs an electrical signal corresponding to the sound waves. The microphone device 1 includes a microphone 10 and a windscreen 20.
[0018] FIG. 2 is a cross-sectional view of the microphone device 1 of FIG. 1 as viewed in the direction of arrow A. FIG. This figure shows the microphone 10 in a non-sectional view, and the windscreen 20 in a sectional view (the same applies to Figures 7, 8, and 9 described later).
[0019] In the following description, the direction toward the top of the paper in Fig. 2 will be referred to as "upward," and the direction toward the bottom of the paper in Fig. 2 will be referred to as "downward." Similarly, the direction toward the left side of the paper in Fig. 2 will be referred to as "leftward," and the direction toward the right side of the paper in Fig. 2 will be referred to as "rightward."
[0020] Microphone configuration Microphone 10 picks up sound waves from a sound source and outputs an electrical signal corresponding to the sound waves. In this embodiment, microphone 10 is, for example, a lavalier microphone. That is, microphone 10 can be worn by a person (speaker or player) during television programs, lectures, sporting events, etc. Microphone 10 is attached to the collar or chest of the user of microphone 10, for example, with a tie pin clip (not shown).
[0021] In the present invention, the microphone may be a narrow-directivity microphone such as a gun microphone.
[0022] The microphone 10 includes a microphone body 11, a cord 12, and a step portion 13.
[0023] The microphone body 11 is directed toward a sound source and picks up sound waves from the sound source. The microphone body 11 has a cylindrical shape with a bottom. The microphone body 11 includes a microphone unit (not shown), a circuit board (not shown), and a sound wave inlet (not shown).
[0024] The microphone unit picks up sound waves introduced into microphone body 11 from a sound wave inlet and converts the sound waves into an electrical signal. The microphone unit is, for example, a capacitor-type electro-acoustic transducer. The microphone unit is housed in microphone body 11. The microphone unit, together with microphone body 11, constitutes a sound pickup section that picks up sound.
[0025] In the present invention, the microphone unit is not limited to a capacitor-type electroacoustic transducer, and may be, for example, a dynamic-type electroacoustic transducer.
[0026] The circuit board is mounted with circuits such as a balanced transmission circuit (not shown) that outputs an audio signal from the microphone unit to an output connector (not shown). The circuit board is housed in microphone body 11.
[0027] The sound wave inlet introduces sound waves from the sound source into the microphone unit. The sound wave inlet is located on the top end surface of the microphone body 11.
[0028] The cord 12 connects the microphone 10 to a transmitter (not shown) that serves as a receiver. The cord 12 outputs an audio signal from the circuit board via a signal line. The cord 12 is inserted into the inside of the stepped portion 13. The transmitter is worn, for example, on the belt or around the waist of the user of the microphone 10.
[0029] The step 13 prevents breakage of the signal line due to bending at the portion where the cord 12 is pulled out from the microphone body 11. That is, the step 13 functions as a so-called cord bushing.
[0030] ●Windscreen configuration
[0031] FIG. 3 is a front view showing an embodiment of a windscreen 20 according to the present invention. FIG. 4 is a perspective view of the windscreen 20. As shown in FIG. FIG. 5 is a bottom view of the windscreen 20. Figure 6 shows the windscreen in Figure 3. 20 FIG. 2 is a cross-sectional view taken along the arrow B.
[0032] The windscreen 20 protects the sound pickup section, thereby reducing wind noise such as wind noise caused by wind outside the microphone device 1 and so-called pop noise generated by the microphone unit due to the breath of the user of the microphone device 1. The windscreen 20 is detachably attached to the microphone 10. The windscreen 20 is an example of a "microphone windscreen" according to the present invention. The windscreen 20 includes a windscreen main body 21 and a detachable member 22.
[0033] The windscreen main body 21 is detachably attached to the microphone 10 by the detachable member 22. The windscreen main body 21 covers the periphery of the microphone main body 11 to protect the sound pickup section, thereby reducing wind noise caused by wind, exhaled air, and the like from outside the microphone device 1. The windscreen main body 21 is molded from a porous elastic material such as polyurethane. The windscreen main body 21 is substantially cylindrical with a rounded top and a closed-end cylindrical shape with an open bottom end (one end). As will be described later, the bottom end of the windscreen main body 21 is located within a movable range in which the claw portion 224 of the detachable member 22 can be bent. The windscreen main body 21 has an insertion hole 211h.
[0034] The insertion hole 211h accommodates the microphone body 11 inserted into the insertion hole 211h. The insertion hole 211h is a cylindrical hole that is open at the bottom end (one end) and closed at the top end (the other end). The insertion hole 211h is arranged inside the windscreen main body 21. The opening of the insertion hole 211h is arranged on the bottom end surface of the windscreen main body 21. The bottom surface of the insertion hole 211h (the closed surface of the insertion hole 211h) is Windscreen body 21 It is located above the center.
[0035] The inner diameter of the insertion hole 211h is smaller than the outer diameter of the microphone body 11. That is, when the microphone body 11 is inserted into and accommodated in the insertion hole 211h, the inner diameter of the insertion hole 211h expands to the same diameter as the outer diameter of the microphone body 11.
[0036] The outer diameter of the windscreen main body 21 is configured to taper (become smaller) in the vertical direction from approximately the center toward the upper end. That is, the outer diameter of the windscreen main body 21 tapers in the vertical direction from approximately the center toward the upper end. In other words, the outer peripheral surface of the windscreen main body 21 inclines toward the radial center of the windscreen main body 21 in the vertical direction from approximately the center toward the upper end.
[0037] In the present invention, the shape of the windscreen main body is not limited to the shape in this embodiment. That is, for example, the outer peripheral surface of the windscreen main body may be cylindrical and not inclined in the vertical direction.
[0038] The detachable member 22 makes it easy to attach and detach the windscreen 20 to and from the microphone 10. The detachable member 22 is made of, for example, a thermoplastic elastomer resin and is molded from an elastic member having elasticity. The detachable member 22 covers the outer periphery of the lower end (one end) of the windscreen main body 21 and is joined (fixed) to the lower end of the windscreen main body 21. The detachable member 22 is joined to the windscreen main body 21 by, for example, an adhesive (not shown). The detachable member 22 is gripped by the user when the windscreen 20 is attached to or detached from the microphone 10.
[0039] When the detachable member 22 is coupled to the windscreen main body 21, the outer peripheral surface of the detachable member 22 is continuous in the vertical direction with the outer peripheral surface of the windscreen main body 21. In other words, the detachable member 22 has an outer peripheral surface that is continuous in the vertical direction with the outer peripheral surface of the windscreen main body 21.
[0040] The detachable member 22 includes a grip portion 221, an engagement claw 222, an insertion hole 223h, a claw portion 224, and a notched groove 225.
[0041] The grip portion 221 is held by the user when the windscreen 20 is attached to or detached from the microphone 10. The grip portion 221 is ring-shaped. The grip portion 221 covers the outer periphery of the lower end of the windscreen main body 21. The grip portion 221 functions as a side wall of the detachable member 22. In other words, the grip portion 221 is an example of a "side wall portion" in the present invention.
[0042] When gripped by a user, grip portion 221 can be deformed into an oval ring shape by the force with which the user grips grip portion 221. When the user releases the force with which grip portion 221 is gripped by grip portion 221, the deformed grip portion 221 returns to its original shape by elastic force.
[0043] The engagement claws 222 are arranged at the upper end of the grip portion 221 and protrude inward (inside) of the grip portion 221. The engagement claws 222 include six engagement claws 222 (only two engagement claws are shown in FIG. 6). The engagement claws 222 are arranged at predetermined intervals in the circumferential direction of the grip portion 221.
[0044] In this embodiment, the configuration of each of the engaging claws 222 is the same. In the following description, the engaging claws 222 are all given the same reference numeral "222" and are collectively referred to as "engaging claws 222."
[0045] When the detachable member 22 is joined to the windscreen main body 21, the engagement claws 222 bite into the outer peripheral surface of the lower part of the windscreen main body 21. Therefore, the joining between the windscreen main body 21 and the detachable member 22, which are joined with an adhesive, becomes stronger.
[0046] In the present invention, the number of engaging claws is not limited to "6", that is, for example, the number of engaging claws may be "1" or a number other than "6".
[0047] The insertion hole 223h is a hole into which the microphone body 11 is inserted. The insertion hole 223h is an opening formed on the inner circumferential surface of the grip portion 221.
[0048] The claws 224 are formed integrally with the gripping portion 221 and are connected to the lower end of the gripping portion 221. The claws 224 are located below the opening of the insertion hole 211h. In this embodiment, the detachable member 22 includes six claws 224. The claws 224 are arranged at equal intervals in the circumferential direction of the gripping portion 221, with a predetermined gap between each other.
[0049] In this embodiment, the configuration of each of the claw portions 224 is the same. In the following description, the claw portions 224 are all given the same reference numeral "224" and are collectively referred to as "claw portions 224."
[0050] Claw portion 224 includes a bent portion 2241 and a connecting portion 2242. A half of claw portion 224 on the grip portion 221 side is folded back inside grip portion 221 so as to form a downwardly convex U-shape in cross section, thereby constituting connecting portion 2242. In other words, connecting portion 2242 is U-shaped in cross section.
[0051] The remaining half of claw portion 224 is disposed along the left-right direction to form bent portion 2241. That is, bent portion 2241 protrudes from connecting portion 2242 radially inward of grip portion 221 and is cantilevered by connecting portion 2242. In other words, claw portion 224 protrudes inward from the lower end (one end) of grip portion 221.
[0052] One end of the connecting portion 2242 is connected to the grip portion 221, and the other end of the connecting portion 2242 is folded back inside the insertion hole 223h and connected to the bent portion 2241. That is, the connecting portion 2242 connects the grip portion 221 and the bent portion 2241. Here, when the bent portion 2241 is arranged along the left-right direction, the claw portion 224 is located in the "normal position" according to the present invention. In other words, the claw portion 224 is located in an unbent normal position before the microphone body 11 is inserted from the insertion hole 223h toward the insertion hole 211h (before the windscreen 20 is attached to the microphone 10). The bent portion 2241 is located below the opening of the insertion hole 211h within the insertion hole 223h. The distance from the connecting portion 2242 to the tip of the bent portion 2241 is longer than the distance from the connecting portion 2242 to the opening of the insertion hole 211h. The claw portion 224 configured in this manner, excluding a portion of the connecting portion 2242, is disposed in the insertion hole 223h.
[0053] When viewed from below, the diameter of an imaginary circle C1 (see FIG. 5) formed by connecting the tip ends (radially inner ends of grip portion 221) of bent portion 2241 is smaller than the outer diameter of microphone body 11, slightly larger than the outer diameter of step portion 13, and larger than the outer diameter of cord 12. When viewed from below, imaginary circle C1, insertion hole 223h, and insertion hole 211h are each arranged concentrically.
[0054] The tabs 224 are elastic and bendable. Therefore, when the windscreen 20 is attached (mounted) to the microphone 10, the tabs 224 are bent upward from a normal position. Specifically, the bent portions 2241 are bent so as to rise upward from the connection portion with the connecting portion 2242 as a starting point. At this time, the tip of the bent portion 2241 is pushed into the insertion hole 211h so as to expand the insertion hole 211h. In other words, the tabs 224 are bent toward the insertion hole 211h while the microphone body 11 (a part of the microphone body 11) is inserted from the insertion hole 223h toward the insertion hole 211h (while the windscreen 20 is attached to the microphone 10 (during attachment)). When the microphone body 11 is completely accommodated in the insertion hole 211h (when the microphone body 11 passes over the claw portion 224), the claw portion 224 returns to its original state (normal position) due to its own elastic force. In other words, the claw portion 224 returns to its normal position after the microphone body 11 is accommodated in the insertion hole 211h. Specifically, the bent portion 2241 is bent radially inward of the grip portion 221 from the connecting portion with the connecting portion 2242 as a starting point, and is arranged along the left-right direction.
[0055] On the other hand, when the windscreen 20 is removed from the microphone 10 (when it is dismounted), the claw portion 224 is bent downward from its normal position. Specifically, the bent portion 2241 is bent downward from the connecting portion 2242 as a starting point. In other words, while the windscreen 20 is being removed from the microphone 10 (while the microphone body 11 is pulled out of the insertion hole 223h), the claw portion 224 is bent toward the opposite side from the insertion hole 211h. When the windscreen 20 is removed from the microphone 10 (when dismounting is complete), the claw portion 224 returns to its original state (normal position) due to its own elasticity. Specifically, the bent portion 2241 springs upward from the connecting portion 2242 as a starting point toward the inside of the radial direction of the grip portion 221, and is arranged along the left-right direction.
[0056] In the claw portion 224 that can be bent in this manner, the connecting portion 2242 is formed in a U-shape, so that the stress acting on the claw portion 224 when the bending portion 2241 is bent is dispersed by the connecting portion 2242. Also, by forming the connecting portion 2242 in a U-shape, a so-called hemming structure is formed, and the strength of the claw portion 224 is increased. Furthermore, by forming the connecting portion 2242 in a U-shape, the connecting position of the bending portion 2241 with the connecting portion 2242 is higher in the vertical direction than the lower portion (bottom) of the connecting portion 2242. That is, the detachable member 22 (claw Department 224), a recessed space is formed between the lower part (bottom) of connecting part 2242 and the position of bent part 2241. Therefore, when windscreen 20 is attached to microphone 10, bent part 2241, which is positioned within this space, serves as a guide for positioning microphone body 11 to insert it into the center of insertion hole 211h.
[0057] In the present invention, the number of claw portions is not limited to "6". That is, for example, the number of claw portions may be "1" or a number other than "6".
[0058] The notched grooves 225 are arranged between the respective claw portions 224. That is, for example, the number of the notched grooves 225 is "6." The notched grooves 225 are arranged radially on the lower part of the detachable member 22. Some of the notched grooves 225 are arranged in the grip portion 221.
[0059] ●Attaching and detaching the windscreen Next, the attachment and detachment of the windscreen will be described, i.e., "attaching the windscreen 20 to the microphone 10" when the windscreen 20 is attached to the microphone 10, and "removing the windscreen 20 from the microphone 10" when the windscreen 20 is removed from the microphone 10.
[0060] Attaching the windscreen 20 to the microphone 10 FIG. 7 is an exploded view of the microphone device 1, showing the microphone 10 before it is inserted into the windscreen 20. As shown in FIG.
[0061] When attaching the windscreen 20 to the microphone body 11, the user grasps the grip portion 221 and the microphone body 11 or the cord 12, and brings the microphone body 11 and the windscreen 20 closer together. Before the microphone body 11 is inserted from the insertion hole 223h toward the insertion hole 211h, the tab portion 224 is in a normal, unfolded position.
[0062] First, the microphone body 11 is inserted into the insertion hole 223h from the upper end side of the microphone body 11.
[0063] At this time, the upper end of the microphone body 11 abuts against the claw portion 224, which is located in its normal position. Next, when the microphone body 11 is pushed toward the insertion hole 211h, the bent portion 2241 (claw portion 224) abuts against the outer peripheral surface of the microphone body 11, and the bent portion 2241 is bent upward from its normal position (toward the insertion hole 211h). The tip of the bent portion 2241 presses against the open end of the windscreen body 21 (the open end of the insertion hole 211h). That is, the diameter of the lower end (open end) of the insertion hole 211h of the windscreen body 21 is expanded by the claw portion 224 while the microphone body 11 is inserted from the insertion hole 223h toward the insertion hole 211h. Therefore, the microphone body 11 is inserted into the insertion hole 211h so as to slide over the bent portion 2241, and the bent portion 2241 functions as a guide. As a result, the microphone body 11 can be easily inserted into the insertion hole 211h.
[0064] FIG. 8 is a cross-sectional view showing the microphone 10 while it is being inserted into the windscreen 20. As shown in FIG. This figure shows the state in which the windscreen 20 is being attached to the microphone 10 (in the middle of being attached).
[0065] The microphone body 11 continues to be inserted (pushed) from the insertion hole 223h toward the insertion hole 211h. While the microphone body 11 is being inserted from the insertion hole 223h toward the insertion hole 211h, the bent portion 2241 (claw portion 224) is bent upward (toward the insertion hole 211h) from its normal position while abutting against the outer circumferential surface of the microphone body 11. The microphone body 11 is inserted into the insertion hole 211h while expanding the diameter of the insertion hole 211h.
[0066] FIG. 9 is a cross-sectional view showing the state after the microphone 10 has been inserted into the windscreen 20. As shown in FIG. This figure shows the state when the microphone body 11 is completely housed in the insertion hole 211h (when the microphone body 11 has passed the claw portion 224).
[0067] When the microphone body 11 is completely inserted (housed) in the insertion hole 211h (when the microphone body 11 passes over the claw portion 224), the claw portion 224 returns to its original state (normal position) due to its own elastic force. That is, the state in which the bent portion 2241 (claw portion 224) abuts against the outer circumferential surface of the microphone body 11 is released. In other words, the bent portion 2241 (claw portion 224) returns to its normal position after the microphone body 11 is inserted (housed) in the insertion hole 211h. At this time, the bent portion 2241 (claw portion 224) returns to its normal position with momentum due to its elastic force. As a result, the user can recognize that the attachment of the windscreen 20 to the microphone 10 is complete by feeling the sensation (click) that the bent portion 2241 (claw portion 224) has returned to its normal position.
[0068] When the tabs 224 return to their normal positions, the microphone body 11 is pushed back slightly downward by the elastic force of the windscreen body 21. As a result, the step 13 of the microphone 10 is positioned within the imaginary circle C1. As described above, the diameter of the imaginary circle C1 is smaller than the outer diameter (diameter) of the microphone body 11. Therefore, the bent portion 2241 (tabs 224) is positioned so as to protrude downward from the microphone body 11. As a result, the tabs 224 hold the microphone body 11 in place. Therefore, the windscreen 20 is less likely to come off the microphone 10 easily.
[0069] In this way, the windscreen 20 is attached to the microphone 10. At this time, the elastic force of the windscreen main body 21 fastens the microphone main body 11 to the windscreen main body 21. As a result, the windscreen 20 is fixed to the microphone 10 by the fastening force against the microphone 10 and the frictional force generated between the windscreen 20 and the microphone 10 (hereinafter collectively referred to as the "holding force"). Also, as described above, the claws 224 hold the microphone main body 11, so even if the holding force decreases due to deterioration of the windscreen main body 21 over time, the claws 224 make it difficult for the windscreen 20 to come off the microphone 10. In other words, the windscreen 20 is prevented from falling off the microphone 10.
[0070] Removing the windscreen 20 from the microphone 10
[0071] When the windscreen 20 is to be removed from the microphone body 11, the user grasps the grip portion 221 and the cord 12 and moves (pulls out) the microphone 10 below the windscreen 20.
[0072] At this time, first, the lower end of the microphone body 11 abuts against the claw portion 224 located at the normal position. Next, when the microphone body 11 is pulled in the direction (downward) to be pulled out of the insertion hole 211h, the bending portion 2241 (claw portion 224) is bent downward from the normal position (toward the opposite side from the insertion hole 211h).
[0073] The microphone body 11 continues to be pulled in the direction (downward) to be extracted from the insertion hole 211h. While the microphone body 11 is being pulled in the direction (downward) to be extracted from the insertion hole 211h, the bent portion 2241 (claw portion 224) is bent downward from its normal position (toward the opposite side from the insertion hole 211h) while abutting against the outer circumferential surface of the microphone body 11.
[0074] The microphone body 11 is further pulled in the direction (downward) of removal from the insertion hole 211h, and is thereby removed from the insertion hole 211h and the insertion hole 223h. When the microphone body 11 is completely removed from the insertion hole 223h (when the microphone body 11 passes the claw portion 224), the claw portion 224 returns to its original state (normal position) due to its own elastic force. That is, the state in which the bent portion 2241 (claw portion 224) abuts against the outer circumferential surface of the microphone body 11 is released. In other words, the bent portion 2241 (claw portion 224) returns to its normal position after the microphone body 11 is removed from the insertion hole 223h. At this time, the bent portion 2241 (claw portion 224) returns to its normal position with momentum due to the elastic force. As a result, the user can sense that the bent portion 2241 (claw portion 224) has returned to its normal position (a clicking sensation), and can thereby understand that the removal of the windscreen 20 from the microphone 10 has been completed.
[0075] In this way, when the windscreen 20 is removed from the microphone body 11, the user grasps the grip portion 221 and the cord 12. In other words, when the windscreen 20 is removed from the microphone body 11, the windscreen body 21 is not pulled. Therefore, the windscreen body 21 is not torn (broken). Furthermore, when the windscreen 20 is removed from the microphone body 11, the folding portion 2241 (claw portion 224) is folded toward the opposite side from the insertion hole 211h while abutting against the outer peripheral surface of the microphone body 11. Therefore, the user can remove the windscreen 20 from the microphone body 11 without applying excessive force.
[0076] Summary According to the embodiment described above, the detachable member 22 coupled to the windscreen main body 21 includes an insertion hole 223h and a claw portion 224. The claw portion 224 is located in a normal, unbent position before the microphone 10 (microphone main body 11) is inserted from the insertion hole 223h toward the insertion hole 211h. The claw portion 224 is bent upward (toward the insertion hole 211h) from the normal position while the microphone 10 (microphone main body 11) is being inserted from the insertion hole 223h toward the insertion hole 211h. Therefore, the microphone 10 is inserted into the insertion hole 211h so as to slide along the claw portion 224 (bent portion 2241), and the claw portion 224 functions as a guide. As a result, the windscreen 20 can be easily attached to the microphone 10. Furthermore, the tabs 224 return to their normal positions when the microphone body 11 is completely inserted (housed) in the insertion hole 211h (after the microphone 10 is housed in the insertion hole 211h). As a result, the user can sense (click) that the bent portions 2241 (tabs 224) have returned to their normal positions, and thus understand that attachment of the windscreen 20 to the microphone 10 is complete. Furthermore, because the tabs 224 that have returned to their normal positions are positioned so as to protrude below the microphone body 11, they serve to hold down the microphone body 11. As a result, even if the holding force of the windscreen body 21 decreases due to deterioration over time, the tabs 224 make it difficult for the windscreen 20 to come off the microphone 10. In other words, the windscreen 20 is prevented from falling off the microphone 10 at sporting venues and the like.
[0077] Furthermore, according to the embodiment described above, tab portion 224 is bent while abutting against the outer peripheral surface of microphone 10 while microphone 10 is being inserted from insertion hole 223h toward insertion hole 211h. Therefore, microphone body 11 is inserted into insertion hole 211h so as to slide along bent portion 2241, and bent portion 2241 functions as a guide. As a result, as described above, attachment of windscreen 20 to microphone 10 is facilitated.
[0078] Furthermore, according to the embodiment described above, the tab 224 is bent toward the opposite side from the insertion hole 211h while the microphone 10 is being removed from the insertion hole 223h. The tab 224 returns to its normal position after the microphone 10 is removed from the insertion hole 223h. Therefore, the user can recognize that the removal of the windscreen 20 from the microphone 10 is complete by sensing (a clicking sensation) that the bent portion 2241 (tab 224) has returned to its normal position. In addition, while the microphone 10 is being removed from the insertion hole 223h, the tab 224 abuts against the outer peripheral surface of the microphone 10. Therefore, the user can remove the windscreen 20 from the microphone body 11 without applying excessive force.
[0079] Furthermore, according to the embodiment described above, detachable member 22 includes grip portion 221, and claw portion 224 protrudes inward from one end (lower end) of grip portion 221. Therefore, as described above, windscreen 20 is less likely to come off microphone 10 because claw portion 224, which has returned to its normal position, is positioned lower than the lower end of microphone body 11. In other words, windscreen 20 is prevented from falling off microphone 10 at a sporting event venue or the like.
[0080] Furthermore, according to the embodiment described above, the claw portion 224 expands the diameter of the open end of the insertion hole 211h while the microphone 10 is inserted from the insertion hole 223h toward the insertion hole 211h. Therefore, when attaching the windscreen 20 to the microphone 10, the user does not need to enlarge the opening (insertion hole 211h) of the windscreen main body 21 with their own hands. As a result, attaching the windscreen 20 to the microphone 10 becomes easier, and the workability of attaching the windscreen 20 to the microphone 10 improves. Furthermore, because the user does not need to enlarge the opening of the windscreen 20 with their own hands, the risk of the windscreen main body 21 breaking is reduced.
[0081] Furthermore, according to the embodiment described above, the claw portion 224 includes a bent portion 2241 and a connecting portion 2242. The connecting portion 2242 is U-shaped in cross section, with one end of the connecting portion 2242 connected to the grip portion 221 and the other end of the connecting portion 2242 folded back toward the insertion hole 223h and connected to the bent portion 2241. By making the connecting portion 2242 U-shaped, the stress acting on the claw portion 224 when the bent portion 2241 is bent is dispersed. .Ma In addition, by forming the connecting portion 2242 in a U-shape, a so-called hemming structure is formed, and the strength of the claw portion 224 is increased. Furthermore, by forming the connecting portion 2242 in a U-shape, the connecting position of the bent portion 2241 with the connecting portion 2242 is higher than the lower portion (bottom) of the connecting portion 2242 in the vertical direction. Department 224), a recessed space is formed between the lower part (bottom) of connecting part 2242 and the position of bent part 2241. Therefore, when windscreen 20 is attached to microphone 10, bent part 2241, which is positioned within this space, serves as a guide for positioning microphone body 11 to insert it into the center of insertion hole 211h.
[0082] In the embodiment described above, the windscreen 20 is attached to the microphone 10. Alternatively, the windscreen according to the present invention may be attached to other microphones. In other words, the windscreen according to the present invention can be applied to microphones of other types and shapes.
[0083] FIG. 10 is a cross-sectional view showing a state in which another microphone is inserted into the windscreen according to the present invention. This figure shows the state in which the windscreen 20 is being attached to the microphone 10X (in the middle of being attached). This figure also shows the microphone 10X in a non-cross-section, and the windscreen 20 in a cross-section.
[0084] The configuration of microphone 10X is the same as that of microphone 10 in the previously described embodiment, except for the inclusion of acoustic adjustment member 14X. That is, microphone 10X includes microphone body 11, a microphone unit (not shown), a circuit board (not shown), cord 12, step portion 13, and acoustic adjustment member 14X. Except for acoustic adjustment member 14X, components common to microphone 10 are designated by the same reference numerals, and descriptions thereof will be omitted.
[0085] The acoustic adjusting member 14X adjusts the acoustics of the microphone 10X. The acoustic adjusting member 14X is attached to the upper part of the microphone body 11. The outer diameter of the acoustic adjusting member 14X is larger than the outer diameter of the microphone body 11.
[0086] Even when attaching the windscreen 20 to such a microphone 10X, the bending portion 2241 (claw portion 224) of the windscreen 20 is bent toward the insertion hole 211h to fit the outer diameter of the microphone 10X. That is, when the microphone main body 11 is pushed toward the insertion hole 211h, the bending portion 2241 (claw portion 224) is bent toward the insertion hole 211h. The bent bending portion 2241 pushes open the open end of the windscreen main body 21 (the open end of the insertion hole 211h). That is, the lower end of the insertion hole 211h of the windscreen main body 21 Department (Open end) is the microphone body 11 As a result, the microphone body 11 This makes it easier to insert the connector 211 into the insertion hole 211h.
[0087] In this way, the windscreen according to the present invention can be applied to microphones of different shapes. This means that it is not necessary to prepare a dedicated windscreen for each type and size of microphone. As a result, the windscreen according to the present invention can be used for a microphone of one shape and then reused for a microphone of another shape. [Explanation of symbols]
