Abstract

This invention provides a positioning device for fixing a lapel clip microphone to the brim of a hat. The device includes a clamping part and a fixing part. The clamping part clamps and fixes the positioning device to the brim of the hat. The fixing part is connected to the clamping part and is used to fix the lapel clip microphone. When the clamping part is fixed to the brim and the lapel clip microphone is fixed to the fixing part, the microphone's pickup port can point downwards towards the bottom of the hat. When used with a hat, this positioning device serves as a base for fixing the lapel clip microphone to the brim, while simultaneously tilting the microphone's pickup port downwards and pointing it towards the singer's mouth, thereby improving sound pickup and meeting the requirements for high-quality singing. Furthermore, since it is not in the airflow path of the mouth, it also avoids plosive sounds.

Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a positioning device for fixing a lapel microphone to the brim of a hat. Background Technology

[0002] During song performances (such as guitar playing and singing), a microphone is usually needed to capture the singer's voice. Currently, the common practice is to mount the microphone on a special stand and adjust the stand so that the microphone is close to and pointed at the singer's mouth. However, this method has significant drawbacks: the special stand is bulky, inconvenient to carry and use, and requires additional carrying and setup for each performance.

[0003] To overcome the inconvenience of stand-type microphones, compact lavalier microphones have become an alternative. However, in current usage, lavalier microphones are typically clipped to the singer's collar. This method results in the microphone's pickup not pointing towards the singer's mouth, but rather near the neck. While the pickup is acceptable for normal speaking, it is often less than ideal for singing due to the sound production method and directionality. Another approach is to clip the lavalier microphone directly to the brim of the singer's hat (such as a baseball cap). However, with this method, the microphone's pickup usually only points in front of the singer's face, not towards the mouth, thus the pickup effect remains unsatisfactory and fails to meet the requirements for high-quality singing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a positioning device for fixing a lapel microphone to the brim of a hat. This device not only fixes the lapel microphone to the brim of the singer's hat, but also makes the microphone port of the fixed lapel microphone point as close as possible to the singer's mouth, so as to improve the sound pickup effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a positioning device for fixing a lapel clip microphone to the brim of a hat is provided, which is provided with a clamping part and a fixing part;

[0006] The clamping part is used to clamp and fix the positioning device on the brim of the hat;

[0007] The fixing part is connected to the clamping part and is used to fix the lavalier microphone;

[0008] Furthermore, when the clamping part is clamped and fixed on the brim of the hat, and the lapel microphone is fixed to the fixing part, the pickup port of the lapel microphone can point to the bottom of the hat body.

[0009] Furthermore, the clamping part includes an upper clamping arm and a lower clamping arm, the ends of which are close to each other to form a clamping effect.

[0010] Furthermore, the upper clamping arm and the lower clamping arm rely on their own elastic restoring force to bring their ends closer together to form a clamping effect.

[0011] Furthermore, both the upper clamping arm and the lower clamping arm have protrusions on their surfaces that are close to each other to improve clamping stability.

[0012] In a preferred embodiment, the fixing part includes a fixing arm, which serves as a fixing base for the lavalier microphone and is fixedly connected to the clamping part, forming a fixed angle between the two between 70° and 90°.

[0013] Furthermore, the fixing arm and the clamping part are integrally formed.

[0014] In another preferred embodiment, the fixing part includes a fixing arm, which serves as a fixing base for the lavalier microphone and is rotatably connected to the clamping part so that the angle between the fixing arm and the clamping part is adjustable.

[0015] Furthermore, the fixing arm is provided with a receiving area, which is used to receive and clamp the clip of the lavalier microphone.

[0016] Furthermore, one of the walls of the receiving area is a clamping surface, and the clamping surface is provided with a slot;

[0017] When the clip of the lavalier microphone is inserted into the receiving area, the protrusion on the microphone body surface corresponding to the clip can be inserted into the slot, so that the microphone is clamped and fixed on the clamping surface.

[0018] Furthermore, the size of the receiving area is adapted to the external dimensions of the clip.

[0019] Furthermore, the area of ​​the fixing part used to connect with the lavalier microphone is provided with a magnet or magnetically conductive metal to fix the lavalier microphone by magnetic attraction.

[0020] The beneficial effects of this utility model are as follows:

[0021] When used with a hat, the positioning device of this invention serves as a fixed base, securing the lapel microphone to the brim of the hat. It also tilts the microphone's pickup port downwards, pointing it towards the singer's mouth, thus improving sound pickup and meeting the requirements for high-quality singing. Furthermore, since the fixed lapel microphone is not in the airflow path of the mouth, it avoids popping sounds (commonly known as "microphone popping"). Additionally, because the lapel microphone remains relatively stationary with respect to the vocal tract after being fixed to the brim, it is unaffected by head shaking or other movements, thus improving sound pickup stability.

[0029] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0030] Example 1:

[0031] See Figures 1 to 3 This embodiment provides a positioning device 100 for fixing a lapel clip microphone to the brim of a hat, which is provided with a clamping part 110 and a fixing part 120.

[0032] The clamping part 110 is used to clamp and fix the positioning device 100 to the brim 310 of the hat 300.

[0033] The fixing part 120 is connected to the clamping part 110 and is used to fix the lavalier microphone 200.

[0034] And see also Figure 5 When the clamping part 110 clamps and fixes the hat brim 310, and the lapel microphone 200 is fixed to the fixing part 120, the lapel microphone 200 can be tilted, and its pickup port 211 can point downwards towards the hat body 320 of the hat 300. If the hat 300 is worn on the singer's head at this time, then the pickup port 211 of the lapel microphone 200 will roughly point towards the singer's mouth (see...). Figure 5 (The dashed line indicates that) compared to fixing the lapel microphone 200 to the collar, this method can improve the directivity of the pickup port 211, thereby improving the sound pickup effect. At the same time, since the pickup port 211 of the lapel microphone 200 is not located in the air outlet path of the mouth, it can also avoid the occurrence of plosive sounds (the explosive sound produced when airflow accumulates in the mouth and is suddenly released, impacting the microphone diaphragm during the sound production process, commonly known as "pop"). In addition, since the lapel microphone 200 is fixed to the brim of the hat 310, it always remains relatively stationary with respect to the vocal part of the body. Therefore, it is not affected by head shaking or other movements during use, which can improve the stability of sound pickup.

[0035] In a preferred embodiment, the clamping part 110 includes an upper clamping arm 111 and a lower clamping arm 112, the ends of the upper clamping arm 111 and the lower clamping arm 112 being close to each other to form a clamping effect.

[0036] Specifically, the upper clamping arm 111 and the lower clamping arm 112 can be designed as two relatively rotatable clamping arms, with the ends of the two arms brought closer together by a spring, thereby achieving clamping, similar to the principle of a common spring clip. Of course, the upper clamping arm 111 and the lower clamping arm 112 can also be designed to rely solely on their own elastic restoring force to bring their ends closer together to form a clamping effect.

[0037] The embodiment shown in the accompanying drawings adopts the latter solution described above. The upper clamping arm 111 and the lower clamping arm 112 are preferably made of plastic. In their natural state, the ends of the two clamping arms are close to each other. Once the ends of the two clamping arms are pried apart, they will tend to hug each other due to their own elastic restoring force, thereby forming a stable clamping effect.

[0038] Furthermore, the surfaces of the upper clamping arm 111 and the lower clamping arm 112 that are close to each other are provided with protrusions 11a for improving clamping stability, and the protrusions 11a of the upper clamping arm 111 and the lower clamping arm 112 are staggered.

[0039] The protrusion 11a is usually a raised prismatic structure. When clamped, the protrusion 11a of the upper and lower clamping arms press against the upper and lower sides of the brim 310 respectively, which can improve the stability of the clamping.

[0040] Figure 4 This is a structural diagram of the lavalier microphone 200 to which the positioning device 100 of this embodiment is applied. The lavalier microphone 200 includes a microphone body 210 and a clip 220. The microphone body 210 has a microphone port 211 on its top region, and a protruding structure 212 on the surface facing the clip 220. One end of the clip 220 is connected to the top of the microphone body 210, and the clip 220 is rotatable relative to the microphone body 210. In use, the clip 220 is close to the microphone body 210, allowing the lavalier microphone 200 to be held in a predetermined position. To remove the lavalier microphone 200, the clip 220 is pried open, moving away from the microphone body 210, thus removing the lavalier microphone 200 from the predetermined position.

[0041] In this embodiment, the fixing part 120 can have various structural forms, such as clamping structure, snap-fit ​​structure, plug-in structure, locking structure, magnetic attraction, etc., as long as it can fix the lapel microphone 200 and the microphone port 211 of the lapel microphone 200 can point in the previously mentioned direction after fixing.

[0042] In a preferred embodiment, see Figures 1 to 3 The fixing part 120 includes a fixing arm 121, which serves as a fixing base for the lavalier microphone 200 and is fixedly connected to the clamping part 110, forming a fixed angle between 70° and 90° with the lower clamping arm 112. Figures 1 to 3 In the middle, the angle between the fixed arm 121 and the lower clamp arm 112 is approximately 80°. This angle allows the pickup port 211 of the fixed lavalier microphone 200 to point as close as possible to the singer's mouth.

[0043] Specifically, the fixing arm 121 adopts the aforementioned snap-fit ​​structure, which has a receiving area 121a, which is used to receive and clamp the clip 220 of the lavalier microphone 200.

[0044] One of the walls of the receiving area 121a is a clamping surface 121b, which is provided with a slot 121c. When the clip 220 of the lavalier microphone 200 is inserted into the receiving area 121a, the protrusion 212 on the surface of the microphone body 210 corresponding to the clip 220 can be inserted into the slot 121c, so that the lavalier microphone 200 is clamped and fixed on the clamping surface 121b. See [link to relevant documentation]. Figure 6In the embodiment shown in the accompanying drawings, two slots 121c are provided at intervals on the clamping surface 121b. The two slots 121c correspond to two protruding structures 212 on the surface of the microphone body 210, respectively, and are used to allow the two protruding structures 212 to be engaged.

[0045] The clamping surface 121b can be the wall surface of the fixed arm 121 near the lower clamping arm 112, or the wall surface of the fixed arm 121 away from the lower clamping arm 112, or a lateral wall surface connecting the two wall surfaces. Preferably, in the embodiment shown in the accompanying drawings, the clamping surface 121b is the wall surface of the fixed arm 121 away from the lower clamping arm 112. This wall surface is more suitable as the clamping surface 121b for fixing the lavalier microphone 200 because its top is not obstructed.

[0046] Preferably, the dimensions of the receiving area 121a are adapted to the external dimensions of the clip 220. That is, when the clip 220 is inserted into the receiving area 121a, the length, width, and height dimensions of the receiving area 121a are only slightly larger than the length, width, and height dimensions of the inserted portion of the clip 220. This design ensures that after the clip 220 of the lavalier microphone 200 is inserted into the receiving area 121a, there will be no problem of the lavalier microphone 200 becoming loose due to excessive play.

[0047] Preferably, the fixed arm 121, the upper clamping arm 111, and the lower clamping arm 112 form an integrated structure. This integrated structure can be manufactured in one piece using processes such as injection molding or 3D printing. This structure has the advantages of simple appearance, low cost, and no need for assembly.

[0048] Additionally, in the embodiment shown in the accompanying drawings, slots 121d are provided on the two side walls adjacent to the clamping surface 121b. These slots 121d can be holes left during 3D printing to facilitate the disassembly of the support. When in use, a lanyard can be threaded through the slot 121d to carry the positioning device 100 on the user's body or hang it on a backpack, wall, or other location.

[0049] The use of the positioning device 100 in this embodiment will be described below.

[0050] When using the positioning device 100 of this embodiment, the clip 220 of the lapel microphone 200 can be pried open first, and then the clip 220 can be inserted into the receiving area 121a of the fixing arm 121 on the positioning device 100. After that, the microphone body 210 can be pressed down by hand to bring it close to the clip 220, so that the protrusion structure 212 on the surface of the microphone body 210 can be inserted into the slot 121c of the clamping surface 121b. The mating relationship after insertion is as follows: Figure 6As shown; then, clamp the clamping part 110 of the positioning device 100 onto the brim 310 of the hat 300 (usually a baseball cap). When clamping, first align the gap between the upper clamping arm 111 and the lower clamping arm 112 with the edge of the brim 310, and then push the positioning device 100 forcefully so that the clamping part 110 clamps onto the brim 310, with the upper clamping arm 111 and the lower clamping arm 112 located on the upper and lower sides of the brim 310 respectively. Use the elastic restoring force of the upper clamping arm 111 and the lower clamping arm 112 to clamp the brim 310. Then put the hat 300 on the singer's head. Then, the positioning device 100 can be slightly adjusted as needed so that the microphone port 211 of the lavalier microphone 200 is pointed as close as possible to the singer's mouth.

[0051] After the hat 300 is worn, the effect is roughly as shown in the picture. Figure 5 As shown, the microphone port 211 of the lavalier microphone 200 is roughly pointed towards the singer's mouth (see...). Figure 5 The microphone (with a dotted line in the middle) has good sound pickup and can avoid the "pop" phenomenon. Singers do not need a special mounting bracket to secure the microphone; they only need to use the positioning device 100 in this embodiment to fix the lapel microphone 200 to the brim 310 of the hat 300, and then wear the hat 300. After singing, remove the hat 300 and take the positioning device 100 and the lapel microphone 200 off the brim 310. Then, to separate the lapel microphone 200 and the positioning device 100, simply pry the microphone body 210 away from the clip 220, and then pull the clip 220 out of the receiving area 121a, thereby removing the microphone 200.

[0052] Example 2:

[0053] This embodiment also provides a positioning device 100 for fixing a lapel microphone to the brim of a hat. In this embodiment, the fixing part 120 of the positioning device 100 also includes a fixing arm 121, but the difference is:

[0054] See Figure 7 The fixed arm 121, which serves as the fixed base of the lavalier microphone 200, is rotatably connected to the clamping part 110. This connection method gives the fixed arm 121 better adjustability, and the angle of the lavalier microphone 200 can be adjusted by rotating the connection so that its pickup port 211 is more accurately pointed at the singer's mouth.

[0055] There are several ways in which the fixed arm 121 and the clamping part 110 can be rotatably connected. Figure 7A simple and reliable connection method is demonstrated. Specifically, a shaft hole 11b is provided at the end where the upper clamping arm 111 and the lower clamping arm 112 of the clamping part 110 are connected. A connecting shaft 121e that is adapted to the shaft hole 11b is provided at the end of the fixing arm 121 near the clamping part 110. The connecting shaft 121e is engaged in the shaft hole 11b, so that the fixing arm 121 can rotate around the axis of the shaft hole 11b to achieve angle adjustment.

[0056] More specifically, a notch 11b1 is formed in the middle of the shaft hole 11b, and the two ends of the connecting shaft 121e are respectively inserted into the shaft holes 11b on both sides of the notch 11b1. The middle part of the connecting shaft 121e is exposed through the notch 11b1 and connected to the main body of the fixing arm 121.

[0057] There is a certain friction between the outer wall of the connecting shaft 121e and the inner wall of the shaft hole 11b. When it is necessary to drive the fixed arm 121 to rotate, a corresponding external force must be applied to overcome the friction. When the fixed arm 121 is in a stationary state, the friction can effectively lock the position of the connecting shaft 121e, so that it will not easily move, thereby ensuring the stability of the position of the fixed arm 121.

[0058] Typically, the rotation range of the fixed arm 121 is such that the angle between it and the lower clamp arm 112 can be adjusted between 70° and 90°. This angle range allows the fixed arm 121 to have a certain degree of adjustment, enabling the lavalier microphone 200 to be adjusted as needed, so that its pickup port 211 is more accurately pointed at the singer's mouth.

[0059] To meet the needs of other application scenarios, the rotation range of the fixed arm 121 can be designed to be larger. For example, the maximum range of rotation of the fixed arm 121 can be rotated to an angle of 180° or even greater with the lower clamp arm 112. In this way, in the scenario of talking to others, the pickup port 211 of the lapel clip microphone 200 fixed to the brim can be rotated to point in front of the hat wearer's face, so that the pickup port 211 is pointed at the person opposite, thereby improving the sound pickup effect.

[0060] Example 3:

[0061] The difference between this embodiment and the two embodiments mentioned above is that the fixing part 120 uses a magnetic method to fix the lavalier microphone 200.

[0062] Specifically, the area of ​​the fixing part 120 for connecting with the lavalier microphone 200 is provided with a magnet or magnetically conductive metal (the specific structure is not illustrated in the accompanying drawings of this embodiment).

[0063] The lavalier microphone 200 adapted to this embodiment has a magnet or magnetic metal provided in a predetermined area (usually a certain area on the clip 220). In use, the lavalier microphone 200 can be simply attached to the fixing part 120.

[0064] If the predetermined area of ​​the lavalier microphone 200 is a magnet, then a magnet or a magnetically conductive metal can be provided on the fixing part 120. If the predetermined area of ​​the lavalier microphone 200 is a magnetically conductive metal, then a magnet must be provided on the fixing part 120. Only when the above conditions are met can the lavalier microphone 200 be fixed to the fixing part 120 by magnetic attraction.

[0065] Typically, most lavalier microphones 200 on the market have magnets on the clip 220. Therefore, to ensure a sufficiently strong magnetic force during connection, a preferred solution is to also install magnets on the fixing part 120, thereby achieving strong magnetic force and a stable and reliable connection.

[0066] The shape and structure of the fixing part 120 can be varied, as long as it ensures that the lavalier microphone 200 can be properly attached to the fixing part 120 and is not easily shaken. For example, a groove matching the clip 220 can be designed on the fixing part 120, and a magnet can be provided in the groove. When fixing, the clip 220 of the lavalier microphone 200 is aligned and attached to the groove. The groove can limit the left and right shaking of the lavalier microphone 200.

[0067] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
