Description
Technical Field
[0001] This utility model relates to the field of wireless microphone technology, and more specifically, to a noise-canceling wireless microphone converter. Background Technology
[0002] A wireless microphone converter can convert wired audio signals to wireless transmission, and is commonly used in wireless microphone systems for signal conversion. A wireless microphone system typically consists of a transmitter and a receiver, transmitting audio signals wirelessly. The transmitter usually has one or more built-in microphones that convert the sound signal into an electrical signal, and then converts the electrical signal back into a wireless signal using frequency modulation (FM) or phase modulation (PM), which is then transmitted wirelessly. The receiver receives the wireless signal, converts it back into an audio signal, and transmits it to amplification equipment for output, allowing people to hear the corresponding sound.
[0003] Existing wireless microphone converters are typically used in conjunction with wireless microphones and cameras. The wireless microphone is suspended near the sound-producing part and converts the received sound signal into an electrical signal, which is then transmitted to the wireless converter. The wireless converter connects to the camera via wireless signal or wire to achieve audio synchronization during camera recording.
[0004] When a wireless converter is mounted on a camera bracket, it moves with the camera. The camera's movement and subsequent stillness generate vibrations, which in turn cause the wireless converter to vibrate. These vibrations negatively impact the converter's signal reception and transmission, resulting in noise in the final audio output and reduced sound quality. To address these issues, we provide a noise-canceling wireless microphone converter. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides a noise-canceling wireless microphone converter.
[0006] The present invention provides a noise-canceling wireless microphone converter using the following technical solution:
[0007] A noise-canceling wireless microphone converter includes a converter housing. A noise-canceling panel is fixedly attached to the lower side of one side of the converter housing. A suspension assembly is provided on one side of the noise-canceling panel. The suspension assembly includes a suspension housing and a frustum base. Both sides of the suspension housing are fixedly connected to the outer sides of the converter housing via brackets. A snap-fit groove is formed on the inner wall of the suspension housing. The inner wall of the snap-fit groove snaps into the lower outer wall of the frustum base. A circular groove is formed on one side of the suspension housing, and the circular groove communicates with the snap-fit groove. A buffer assembly is provided on the upper interior of the suspension housing for elastically cushioning the frustum base.
[0008] Preferably, the buffer assembly includes an adjusting crossbar, with through connecting rods vertically fixed to the lower ends of both ends of the adjusting crossbar. One end of each of the two through connecting rods slides through into the interior of the suspension housing. A linkage crossbar is fixed between the adjacent side walls of the two through connecting rods inside the suspension housing. An elastic telescopic rod is vertically fixed to the center of the top surface of the linkage crossbar, and one end of the elastic telescopic rod is fixed to the center of the top surface inside the suspension housing.
[0009] Preferably, one end of each of the two through connecting rods is fixedly connected to a compression arc plate, and the outer walls of both compression arc plates are pressed and fitted against the outer wall of the truncated cone.
[0010] Preferably, there are slider grooves on both sides above the snap-fit groove, and the symmetrical sidewalls of the two extrusion arc plates are fixed with limiting sliders, and the outer walls of the two limiting sliders are respectively engaged with the inner walls of the two slider grooves.
[0011] Preferably, a positioning protrusion is fixedly connected to the bottom of the outer wall of the truncated cone, and the outer wall of the positioning protrusion engages with the inner wall groove of the locking groove.
[0012] Preferably, a clamping bracket is installed on one side of the truncated cone.
[0013] In summary, this utility model has the following beneficial technical effects:
[0014] The buffer assembly is mounted above the truncated cone inside the suspension housing. Under the elastic force of the buffer assembly, it can exert a downward elastic compression force on the truncated cone. In addition, the truncated cone serves as the base for mounting the converter housing and the camera bracket. After the suspension assembly and the converter housing are mounted relative to each other, under the gravity of the converter housing, there is a certain gap between the lower outer wall of the truncated cone and the lower inner wall of the locking groove. When the truncated cone vibrates passively, the buffer assembly can buffer the vibration force to a certain extent, thereby reducing the adverse effects on the converter housing during the movement of the camera bracket and ensuring the sound quality of the final product.

[0021] The following is in conjunction with the appendix Figures 1 to 5 The present invention will be described in further detail below.
[0022] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.
[0023] This utility model discloses a noise-canceling wireless microphone converter. (Refer to...) Figures 1 to 5 A noise-canceling wireless microphone converter includes a converter housing 1. A noise-canceling panel 11 is fixedly attached to the lower side of one side of the converter housing 1. A suspension assembly 2 is provided on one side of the noise-canceling panel 11. The suspension assembly 2 includes a suspension housing 21 and a frustum base 22. Both sides of the suspension housing 21 are fixedly connected to the outer sides of the converter housing 1 via brackets. A snap-fit groove 211 is formed on the inner wall of the suspension housing 21, and the inner wall of the snap-fit groove 211 snaps into the lower outer wall of the frustum base 22. A circular groove 212 is formed on one side of the suspension housing 21, and the circular groove 212 communicates with the snap-fit groove 211. A buffer assembly 3 is provided on the upper interior of the suspension housing 21, and the buffer assembly 3 is used to provide elastic cushioning for the frustum base 22.
[0024] Specifically, the converter housing 1 is fixed to the camera bracket through the mutual cooperation between the suspension assembly 2 and the camera bracket. The suspension housing 21 is installed on the frustum base 22 by engaging with the outer wall of the frustum base 22 through the snap-fit groove 211. This allows the frustum base 22 to be adjusted relative to the inside of the suspension housing 21 under the restriction of the snap-fit groove 211. The buffer assembly 3 is installed above the frustum base 22 inside the suspension housing 21. This allows the buffer assembly 3 to exert a downward elastic compression force on the frustum base 22 under the elastic force of the buffer assembly 3. In addition, the frustum base 22 is the base for the relative installation of the converter housing 1 and the camera bracket. After the suspension assembly 2 and the converter housing 1 are installed relative to each other, there is a certain gap between the lower outer wall of the frustum base 22 and the lower inner wall of the snap-fit groove 211 under the gravity of the converter housing 1. When the frustum base 22 is passively vibrated, the buffer assembly 3 can buffer the vibration force to a certain extent, thereby reducing the adverse effects on the converter housing 1 during the movement of the camera bracket and ensuring the sound quality of the final film.
[0025] The silencing panel 11 is installed between the converter housing 1 and the suspension assembly 2, so that when the movable structure of the suspension assembly 2 comes into contact with the converter housing 1, it can be buffered to a certain extent by the elastic force of the silencing panel 11 itself, thereby increasing the installation shock absorption effect of the converter housing 1. The suspension housing 21 realizes the disassembly or installation of the truncated base 22 through the circular groove 212 through which the snap-fit groove 211 passes.
[0026] Reference Figure 2 , Figure 3 as well as Figure 4 The buffer assembly 3 includes an adjusting crossbar 31. Both ends of the adjusting crossbar 31 are vertically fixed to a through connecting rod 32. One end of each of the two through connecting rods 32 slides through into the interior of the suspension housing 21. A linkage crossbar 33 is fixed between the adjacent side walls of the two through connecting rods 32 inside the suspension housing 21. An elastic telescopic rod 34 is vertically fixed at the center of the top surface of the linkage crossbar 33. One end of the elastic telescopic rod 34 is fixed to the center of the top surface inside the suspension housing 21.
[0027] Specifically, by adjusting the crossbar 31, the through connecting rod 32 extends into the interior of the suspension housing 21 and slides between the suspension housing 21 and the through connecting rod 32. This allows the relative length of the through connecting rod 32 extending into the suspension housing 21 to be adjusted by pulling the adjusting crossbar 31. Inside the suspension housing 21, the elastic telescopic rod 34 is installed through the linkage crossbar 33. This allows the two through connecting rods 32 to have an elastic force that elastically compresses towards the frustum base 22 under the elastic telescopic force of the elastic telescopic rod 34, thus achieving an elastic connection between the buffer assembly 3 and the frustum base 22.
[0028] Reference Figure 2 as well as Figure 4 One end of each of the two through connecting rods 32 is fixedly connected to an extruded arc plate 35, and the outer walls of the two extruded arc plates 35 are pressed and adhered to the outer wall of the truncated cone base 22.
[0029] Specifically, the through-link 32 achieves the linkage between the frustum base 22 and the buffer assembly 3 by squeezing the arc plate 35 and the frustum base 22 together.
[0030] Reference Figure 3 as well as Figure 4 The upper sides of the snap-fit groove 211 are each provided with a slider groove 213. The symmetrical sidewalls of the two extrusion arc plates 35 are fixed with limiting sliders 351. The outer walls of the two limiting sliders 351 are engaged with the inner walls of the two slider grooves 213 respectively.
[0031] Specifically, the mutual engagement between the extrusion arc plate 35 and the slider groove 213 through the limiting slider 351, and the stability of the mutual cooperation between it and the locking groove 211, can prevent the limiting slider 351 from detaching from the inner wall of the locking groove 211 when it moves up to the position of the circular groove 212, thereby increasing the rationality of the device structure.
[0032] Reference Figure 2 as well as Figure 5 The bottom of the outer wall of the truncated cone base 22 is fixedly connected to a positioning protrusion 221, and the outer wall of the positioning protrusion 221 engages with the inner wall groove of the locking groove 211.
[0033] Specifically, the truncated cone base 22 is fixed in position by the mutual engagement between the positioning protrusion 221 and the groove on the inner wall of the snap-fit groove 211, so as to prevent the truncated cone base 22 from rotating relative to the converter housing 1 after installation.
[0034] Reference Figure 5 A clamp 222 is installed on one side of the truncated cone base 22.
[0035] Specifically, the truncated cone base 22 clamps and fixes the entire device through the cooperation between the clamp bracket 222 and the camera bracket.
[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0037] The implementation principle of the noise-canceling wireless microphone converter of this utility model embodiment is as follows: the converter housing 1 is fixed to the camera bracket through the mutual cooperation between the suspension assembly 2 and the camera bracket. The suspension housing 21 is installed on the frustum base 22 by the mutual engagement between the locking groove 211 on the suspension housing 21 and the outer wall of the frustum base 22. The buffer assembly 3 is installed above the frustum base 22 inside the suspension housing 21. This allows the buffer assembly 3 to exert a downward elastic compression force on the frustum base 22 under the elastic force of the buffer assembly 3. In addition, the frustum base 22 is used to realize the relative positioning of the converter housing 1 and the camera bracket. The base is installed, and after the suspension assembly 2 is installed opposite to the converter housing 1, under the weight of the converter housing 1, there is a certain gap between the lower outer wall of the frustum base 22 and the lower inner wall of the snap-fit groove 211. When the frustum base 22 is passively vibrated, the buffer assembly 3 can buffer the vibration force to a certain extent, thereby reducing the adverse effects on the converter housing 1 during the movement of the camera mount. The silencing panel 11 is installed between the converter housing 1 and the suspension assembly 2, so that when the movable structure of the suspension assembly 2 comes into contact with the converter housing 1, it can be pushed by the elastic force of the silencing panel 11 itself. To a certain extent, a buffering mechanism is used to enhance the shock absorption effect of the converter housing 1. The through-link 32, linked to the adjusting crossbar 31, extends into the suspension housing 21 and slides between the suspension housing 21 and the through-link 32. This allows for adjustment of the relative length of the through-link 32 within the suspension housing 21 by pulling the adjusting crossbar 31. Inside the suspension housing 21, the elastic telescopic rod 34 is installed via the linked crossbar 33. The through-link 32 achieves a buffering effect between the truncated cone base 22 and the buffer assembly 3 through the mutual compression between the extruded arc plate 35 and the truncated cone base 22. The linkage and compression of the arc plate 35, through the mutual engagement between the limiting slider 351 and the slider groove 213, and the stability of the mutual cooperation between it and the locking groove 211, can prevent the limiting slider 351 from detaching from the inner wall of the locking groove 211 when it moves up to the position of the circular groove 212. The truncated cone base 22 is fixed in position by the mutual engagement between the positioning protrusion 221 and the groove on the inner wall of the locking groove 211, preventing the truncated cone base 22 from rotating relative to the converter housing 1 after installation. The truncated cone base 22 is clamped and fixed to the whole device by the mutual cooperation between the clamp bracket 222 and the camera bracket.
