Detailed implementation manners

[0018] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] Please refer to Figures 1 - 3 As shown, in a first aspect, the present application provides a wireless microphone receiver 1. A user can directly switch the gear of a function switch by rotating an adjustment component 20 to achieve gain and / or volume adjustment. The operation is simple and convenient to use.

[0020] The wireless microphone receiver 1 includes a housing 10, a function switch (not shown in the figure), and an adjustment component 20. The housing 10 has an installation cavity 10a and an installation hole 10b communicating with the installation cavity 10a. The function switch is located in the installation cavity 10a and is connected to the housing 10. The function switch includes at least one of a gain adjustment switch and a volume adjustment switch. The adjustment component 20 is rotatably connected to the housing 10 corresponding to the installation hole 10b. The adjustment component 20 is also connected to the function switch and adjusts the gear of the function switch by rotation.

[0021] The following Figures 1 - 6 will expand and introduce the specific structure of the wireless microphone receiver 1.

[0022] As Figures 1 - 3 shown, the wireless microphone receiver 1 includes a housing 10, a function switch, and an adjustment component 20.

[0023] The housing 10 serves as the casing of the wireless microphone receiver 1; the housing 10 has an installation cavity 10a and an installation hole 10b communicating with the installation cavity 10a. The specific preparation material of the housing 10 is not limited here, and designers can make a reasonable choice according to actual needs; for example, the preparation material of the housing 10 can be, but is not limited to, one of plastics or plastics; thus, the raw material sources are extensive, easy to obtain, and can effectively reduce the cost of the wireless microphone receiver 1. The specific structure of the housing 10 is not limited here, and designers can make a reasonable design according to actual needs; for example, the housing 10 includes a front shell 11 and a rear cover 12, the front shell 11 has the above-mentioned installation hole 10b, and the rear cover 12 is connected to the front shell 11 and jointly encloses the above-mentioned installation cavity 10a with the front shell 11.

[0024] As Figures 1 - 3 shown, the function switch serves as the function key of the wireless microphone receiver 1, and the function switch includes at least one of a gain adjustment switch and a volume adjustment switch; for example, the function switch can only include a gain adjustment switch; or, the function switch can also only include a volume adjustment switch; or, the function switch can further include both a gain adjustment switch and a volume adjustment switch.

[0025] The function switch is located in the installation cavity 10a of the housing 10 and is connected to the housing 10; the specific connection method between the function switch and the housing 10 is not limited here, and designers can make a reasonable design according to actual needs; for example, the function switch can be, but is not limited to, detachably connected to the housing 10 by at least one of screwing, clamping or plugging; or, the function switch can also be, but is not limited to, non-detachably connected to the housing 10 by gluing.

[0026] As Figures 1 - 3 shown, the adjustment assembly 20 serves as the adjustment mechanism of the wireless microphone receiver 1 to adjust the gear of the function switch to meet the needs of users in different scenarios; the specific structure of the adjustment assembly 20 will be introduced in detail below.

[0027] The adjustment component 20 is rotatably connected to the housing 10 corresponding to the mounting hole 10b, and the adjustment component 20 is connected to the function switch and adjusts the gear position of the function switch by rotation. For example, the function switch may have a zero gear position, and a first gear position, a second gear position, and a third gear position sequentially set from low to high; the adjustment component 20 can be gradually rotated clockwise to switch the function switch from the zero gear position to the first gear position, from the first gear position to the second gear position, and from the second gear position to the third gear position in sequence; correspondingly, by gradually rotating the adjustment component 20 counterclockwise, the function switch is sequentially switched from the third gear position to the second gear position, from the second gear position to the first gear position, and from the first gear position to the zero gear position. It should be noted that the adjustment component 20 can switch the function switch from the zero gear position to any gear position, or from any gear position to another gear position by rotation.

[0028] Based on the wireless microphone receiver 1 in the embodiment of the present application, by designing the adjustment component 20 and the function switch, the user can directly switch the gear position of the function switch by rotating the adjustment component 20 to achieve gain and / or volume adjustment. In this way, there is no need to use a terminal to adjust the gain and volume, and the operation is simple and convenient for the user. By integrating the function switch in the wireless microphone receiver 1, the noise caused by the mechanical vibration generated when the user rotates the adjustment component 20 will not affect the wireless microphone transmitter 2, and the sound collection performance of the wireless microphone transmitter 2 can be effectively optimized.

[0029] As Figures 2 - 4 shown, a damping portion is provided on the outer wall of the housing 10 corresponding to the edge of the mounting hole 10b. The adjustment component 20 includes a rotating disk 21 and an elastic member 23; the rotating disk 21 is rotatably connected to the housing 10 corresponding to the mounting hole 10b, and the rotating disk 21 is also connected to the function switch; the elastic member 23 is disposed on the side of the rotating disk 21 facing the mounting hole 10b. During at least a part of the relative rotation of the rotating disk 21 and the housing 10, the elastic member 23 and the damping portion rub against each other.

[0030] Among them, the rotating disk 21 is used as a connecting member of the adjustment component 20. On the one hand, the rotating disk 21 is used for rotatably connecting to the housing 10, and on the other hand, it is used for connecting to the function switch; the specific structure of the rotating disk 21 will be introduced in detail below.

[0031] The elastic member 23 is used as a damping member of the adjustment component 20 for damping cooperation with the damping portion. The elastic member 23 may include, but is not limited to, a spring piece 231 or an elastic bump; and it can be understood that for different specific forms of the elastic member 23, the specific forms of the damping portion dampingly cooperating with it are also different.

[0032] By arranging an elastic member 23 on the side of the rotating disk 21 facing the mounting hole 10b, arranging a damping portion at the edge of the mounting hole 10b corresponding to the outer wall of the housing 10, and achieving damping through the friction between the elastic member 23 and the damping portion, the stability during the relative rotation of the rotating disk 21 and the housing 10 can be effectively enhanced, so as to improve the stability of the function switch gear position adjustment.

[0033] As Figures 2 - 4 shown, the elastic member 23 includes a spring piece 231; the spring piece 231 is connected to the rotating disk 21 in a cantilever shape (that is, one end of the spring piece 231 is connected to the rotating disk 21, and the other end of the spring piece 231 is suspended), and a part of the spring piece 231 is in contact with the damping portion.

[0034] Among them, the specific shape of the spring piece 231 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the spring piece 231 can be, but not limited to, an arc-shaped spring piece 231 or a straight-line spring piece 231. The specific connection method between the spring piece 231 and the rotating disk 21 (specifically the rotating main body 211 introduced below) is not limited here, and the designer can make a reasonable design according to actual needs; for example, the spring piece 231 can be detachably connected to the rotating disk 21 by at least one of screw connection, snap connection or plug connection; for another example, the spring piece 231 can also be non-detachably connected to the rotating disk 21 by bonding, riveting, injection molding or 3D printing.

[0035] By designing the elastic member 23 as the spring piece 231, during at least part of the relative rotation of the rotating disk 21 and the housing 10, the spring piece 231 and the damping portion rotate relative to each other and rub against each other. The damping portion squeezes the spring piece 231 to cause the spring piece 231 to deform, and the spring piece 231 will generate an elastic force that hinders the continued rotation of the damping portion due to the deformation, thereby hindering the relative rotation between the rotating disk 21 and the housing 10, making the rotation of the rotating disk 21 more stable, so as to improve the stability of the function switch gear position adjustment. By designing the elastic member 23 as the spring piece 231, the damping effect can be further ensured, the mechanism can be simplified, and it is convenient for processing. By designing a part of the spring piece 231 to be in contact with the damping portion, it can not only ensure that the spring piece 231 can provide sufficient elastic force but also further reduce the wear during the friction between the spring piece 231 and the damping portion.

[0036] As Figures 2 - 4As shown in the figure, to make the rotation of the rotating disk 21 more stable, it is designed that the number of elastic pieces 231 is multiple, and the multiple elastic pieces 231 are evenly distributed around the hole axis of the mounting hole 10b; the number of damping parts is multiple, and the multiple damping parts are evenly distributed around the hole axis of the mounting hole 10b. Among them, the number of elastic pieces 231 can be but is not limited to two, three, four, five, six or more; the number of damping parts can be but is not limited to two, three, four, five, six or more. For example, in the embodiment of the present application, the number of elastic pieces 231 is four, and the four elastic pieces 231 are equally spaced around the hole axis of the mounting hole 10b (that is, an elastic piece 231 is designed every 90 degrees); the number of damping parts is also four, and the four damping parts are also equally spaced around the hole axis of the mounting hole 10b (that is, a damping part is designed every 90 degrees); and each elastic piece 231 corresponds to a damping part. In this way, when the rotating disk 21 and the housing 10 rotate relative to each other by a preset angle, each elastic piece 231 only rubs against the corresponding damping part.

[0037] As Figures 2 - 4 shown in the figure, the damping part includes a plurality of damping grooves 10c provided along the hole edge of the mounting hole 10b; the free end of the elastic piece 231 protrudes towards the mounting hole 10b and forms a damping ball 2311, and the damping ball 2311 abuts against the groove wall of the damping groove 10c. During at least part of the process of relative rotation between the rotating disk 21 and the housing 10, the damping ball 2311 abuts against the groove walls of different damping grooves 10c in sequence, and the groove wall of the damping groove 10c squeezes the damping ball 2311 to cause the elastic piece 231 to deform, and this deformation will generate an elastic force that hinders the continuous rotation of the damping groove 10c, thereby hindering the relative rotation between the rotating disk 21 and the housing 10, making the rotation of the rotating disk 21 more stable, so as to improve the stability of the function switch gear position adjustment.

[0038] As Figures 2 - 4 shown in the figure, the rotating disk 21 (specifically the rotating main body 211 introduced below) has a through hole 21a; most of the elastic piece 231 is located in the through hole 21a, the elastic piece 231 is connected to the hole wall of the through hole 21a in a cantilever shape, and the damping ball 2311 at the free end of the elastic arm extends outside the through hole 21a.

[0039] As Figure 2 shown in the figure, the housing 10 (specifically the front housing 11 described above) includes a housing body 111 and a convex ring 112; the housing body 111 has the above-mentioned mounting cavity 10a and the above-mentioned mounting hole 10b; the convex ring 112 is provided on the outer wall of the housing body 111 and is arranged around the mounting hole 10b in a circle; the above-mentioned damping groove 10c is provided on the convex ring 112.

[0040] Of course, the damping portion may also include a plurality of damping protrusions (not shown in the figure) provided along the edge of the mounting hole 10b; the free end of the elastic piece 231 is recessed away from the mounting hole 10b to form a damping groove (not shown in the figure), and the groove wall of the damping groove abuts against the damping protrusion. During at least part of the relative rotation of the rotating disk 21 and the housing 10, the groove wall of the damping groove abuts against different damping protrusions in sequence, and the damping protrusion presses against the groove wall of the damping groove to cause the elastic piece 231 to deform. This deformation generates an elastic force that hinders the continuous rotation of the damping protrusion, thereby hindering the relative rotation between the rotating disk 21 and the housing 10, making the rotation of the rotating disk 21 more stable, and improving the stability of the function switch gear position adjustment.

[0041] As Figures 2 - 4 shown, the rotating disk 21 includes a rotating body 211, a connecting portion 212, and a driving portion 213. The rotating body 211 covers at least part of the mounting hole 10b; the elastic member 23 is disposed on the side of the rotating body 211 facing the mounting hole 10b. The connecting portion 212 is disposed on the side of the rotating body 211 facing the mounting hole 10b; the rotating body 211 is rotatably connected to the housing 10 through the connecting portion 212. The driving portion 213 is disposed on the side of the rotating body 211 facing the mounting hole 10b, and the driving portion 213 is connected to the function switch.

[0042] Among them, the rotating body 211 is the main bearing part of the rotating disk 21; the specific structure of the rotating body 211 is not limited here, and designers can make reasonable designs according to actual needs. For example, the rotating body 211 can be, but is not limited to, a disk-shaped structure. Along the axis direction of the mounting hole 10b, the projection of the rotating disk 21 in the plane where the orifice of the mounting hole 10b is located can partially cover the orifice of the mounting hole 10b or completely cover the orifice of the mounting hole 10b.

[0043] The connecting portion 212, as one of the connecting portions of the rotating disk 21, is used to connect to the housing 10 to achieve the rotational connection between the rotating disk 21 and the housing 10; the specific connection method between the connecting portion 212 and the rotating body 211 is not limited here, and designers can make reasonable designs according to actual needs; for example, when the connecting portion 212 and the rotating body 211 are of a split structure, the connecting portion 212 can be detachably connected to the rotating body 211 by at least one of screwing, clamping, or plugging, etc., and the connecting portion 212 can also be non-detachably connected to the rotating body 211 by gluing or riveting, etc.; for another example, when the connecting portion 212 and the rotating body 211 are of an integral structure, the connecting portion 212 can be integrally formed with the rotating body 211 by injection molding or 3D printing, etc.

[0044] The drive unit 213, as another connecting portion 212 of the rotating disk 21, is used to connect to the function switch to adjust the gear position of the function switch by rotating the rotating disk 21. The drive unit 213 may include a drive rod; one end of the drive rod is connected to the rotating body 211, and the other end of the drive rod is connected to the function switch. The specific connection method between the drive unit 213 and the rotating body 211 is not limited here, and designers can reasonably design it according to actual needs. For example, when the drive unit 213 and the rotating body 211 are separated structures, the drive unit 213 can be, but is not limited to, detachably connected to the rotating body 211 by at least one of screwing, snapping, or plugging. The drive unit 213 can also be, but is not limited to, non-detachably connected to the rotating body 211 by gluing or riveting. For another example, when the drive unit 213 and the rotating body 211 are integrated structures, the drive unit 213 can be, but is not limited to, being integrally formed with the rotating body 211 by injection molding or 3D printing.

[0045] By designing the rotating body 211, the connecting part 212 and the driving part 213, the rotating body 211, the connecting part 212 and the driving part 213 cooperate with each other to realize the rotational connection between the knob cover 24 and the shell 10, and the connection between the knob cover 24 and the function switch, which has a simple structure and is easy to process.

[0046] like Figures 2 - 4 As shown, the connecting portion 212 includes a hook 2121; the fixed end of the hook 2121 is connected to the rotating body 211, and the hook end of the hook 2121 passes through the mounting hole 10b and is hooked to the housing 10. The number of hooks 2121 can be one or more (two or more). For example, in the embodiment of the present application, the number of hooks 2121 is four, and the four hooks 2121 are evenly distributed around the hole axis of the mounting hole 10b. When installing the rotating disk 21, as the hook 2121 passes through the mounting hole 10b, the wall of the mounting hole 10b squeezes the hook 2121, causing the hook 2121 to elastically deform in a direction deviating from the axis of the mounting hole 10b. After the hook end of the hook 2121 passes through the mounting hole 10b and disengages from the wall of the mounting hole 10b, the hook 2121 recovers its deformation in a direction deviating from the axis of the mounting hole 10b under the action of the elastic restoring force corresponding to the elastic deformation. At this time, the hook end of the hook 2121 is hooked on the housing 10, thereby achieving the installation between the rotating disk 21 and the housing 10. It should be noted that there is a gap between the hook end of the hook 2121 and the edge of the inner wall of the housing 10 corresponding to the mounting hole 10b, so that the rotating disk 21 can rotate relative to the housing 10 under the action of an external force.

[0047] Of course, the connecting portion 212 may also include a rotating shaft (not shown in the figure); one end of the rotating shaft is connected to the rotating body 211, and the other end of the rotating shaft is connected to the housing 10; in this way, the rotational connection between the rotating disk 21 and the housing 10 can be achieved.

[0048] As Figures 2 - 3 shown, the adjusting assembly 20 further includes a knob cover 24; the knob cover 24 covers the mounting hole 10b and is connected to the rotating disk 21. The specific connection manner between the knob cover 24 and the rotating disk 21 is not limited herein, and the designer can make a reasonable design according to actual needs; for example, the knob cover 24 can be detachably connected to the rotating disk 21 by at least one of screwing, clamping or plugging; for another example, the knob cover 24 can also be non-detachably connected to the rotating disk 21 by gluing or riveting. By designing the knob cover 24, the knob cover 24 covers the mounting hole 10b to achieve the sealing of the mounting hole 10b, so as to achieve an effective waterproof and dustproof effect. Of course, the peripheral edge of the knob cover 24 is provided with anti-slip lines 241, so as to facilitate the user to rotate the knob cover 24.

[0049] The other structural designs of the wireless microphone receiver 1 can include one or more of the following embodiments, but are not limited thereto.

[0050] As Figure 5 shown, in the first embodiment, the wireless microphone receiver 1 further includes a function indicator light 31; the function indicator light 31 is disposed on the top wall of the housing 10, and the function indicator light 31 is used to indicate the current state of the function switch. Among them, the function indicator light 31 can be detachably connected to the top wall of the housing 10 by at least one of screwing, clamping or plugging. When the function indicator light 31 is lit, it is used to indicate that the function switch is in the working state (that is, in any one of the above first gear, second gear and third gear); when the function indicator light 31 is extinguished, it is used to indicate that the function switch is in the non-working state (that is, in the above zero gear). By designing the function indicator light 31, the user can confirm the current state of the function switch according to the function indicator light 31, improving the use convenience of the wireless microphone receiver 1.

[0051] As Figure 5As shown, in the second embodiment, the wireless microphone receiver 1 further includes an adjustment degree indicator light 32; the adjustment degree indicator light 32 is arranged on the housing 10 and below the adjustment assembly 20, and the adjustment degree indicator light 32 is used to indicate the gear of the function switch. Among them, the adjustment degree indicator light 32 can be detachably connected to the side wall of the housing 10 by at least one of screwing, clamping or plugging and other methods. The adjustment degree indicator light 32 includes a plurality of lamp beads; for example, taking the adjustment degree indicator light 32 including three lamp beads as an example; when one of the lamp beads is lit, it indicates that the function switch is in the above first gear; when two of the lamp beads are lit, it indicates that the function switch is in the above second gear; when all three lamp beads are lit, it indicates that the function switch is in the above third gear. By designing the adjustment degree indicator light 32, the user can confirm the gear of the function switch according to the adjustment degree indicator light 32, improving the use convenience of the wireless microphone receiver 1.

Among them, the type of the external connection interface 34 can be but not limited to a USB-A interface, a USB-C interface or a Type-c interface, etc. By designing the noise reduction button 33, the user can select to trigger the noise reduction button 33 according to the actual application scenario to reduce noise and improve clarity. By designing the external connection interface 34, the wireless microphone receiver 1 can be connected to an external electronic device such as a camera through the external connection interface 34, improving the use convenience of the wireless microphone receiver 1.

[0054] As Figure 6 shown, in the fifth embodiment, the wireless microphone receiver 1 further includes a charging interface 37; the charging interface 37 is arranged on the bottom wall of the housing 10. By designing the charging interface 37, when the power of the wireless microphone receiver 1 is too low or zero, the wireless microphone charging bin 3 can effectively charge the wireless microphone receiver 1 through the charging interface 37.

[0055] As Figures 1 - 2As shown, in the sixth embodiment, the wireless microphone receiver 1 further includes a lapel structure 38; the lapel structure 38 is disposed on the side wall of the housing 10 opposite to the adjustment component 20.
