[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0032] The following combines Figures 1 to 9 to describe an adjustable wireless microphone of the present invention.
[0033] As Figure 1 and Figure 2 shown, in one embodiment, an adjustable wireless microphone includes a microphone body, a micro control unit 220 and a decoding chip 210. The microphone body includes a housing 100, a switch 300, a microphone volume adjustment component 410, a reverberation volume adjustment component 420 and a sound pickup device 500. The sound pickup device 500 is installed at one end of the housing 100. The switch 300, the microphone volume adjustment component 410 and the reverberation volume adjustment component 420 are all installed on the housing 100, and one ends of the switch 300, the microphone volume adjustment component 410 and the reverberation volume adjustment component 420 located inside the housing 100 are in contact with the micro control unit 220 for enabling the micro control unit 220 to obtain control instructions. The micro control unit 220 is used to obtain control instructions and send the control instructions to the decoding chip 210. The decoding chip 210 is used to decode the control instructions and send the decoded control instructions to the audio system through the radio frequency antenna 230, so as to adjust the microphone volume or the reverberation volume. The decoding chip 210, the micro control unit 220 and the radio frequency antenna 230 are all installed inside the microphone body.
[0034] It should be noted that the microphone body integrates IR signal transmission technology to realize the functions of adjusting the microphone volume and reverberation volume. The signal is transmitted to the mixing console after being received and modulated. For the microphone housing 100, windows are opened on the aluminum alloy housing 100 tube body for installing lenses and fixing them with screws. A power switch button and two adjustment sliding or pressing buttons are provided on it for adjusting the microphone volume and reverberation volume respectively. The specific structure is shown as Figure 8 and Figure 9 shown.
[0035] For the above adjustable wireless microphone, by installing the switch 300, the microphone volume adjustment member 410 and the reverberation volume adjustment member 420 on the housing 100, and the ends of the switch 300, the microphone volume adjustment member 410 and the reverberation volume adjustment member 420 located inside the housing 100 are in contact with the micro control unit 220, so that the micro control unit 220 can obtain control instructions. Then, by using the decoding chip 210 to decode the control instructions obtained by the micro control unit 220, and using the radio frequency antenna 230 to send the decoded control instructions, the wireless microphone can perform custom adjustment on relevant parameters. Compared with traditional microphones, it has more functions. The user can directly adjust the sound effect and reverberation effect of the sound through the volume adjustment member set on the microphone, so as to make the mixing reach the best effect faster without going to the mixing console.
[0036] It should be noted that the decoding chip 210 in this embodiment can adopt a high-quality chip to achieve high-fidelity digital transmission for wireless high-quality voice transmission and emission. The frequency band range covered by the chip is: V band 160 - 270 MHz and U band 500 - 980 MHz. In addition, pi / 4 DQPSK digital modulation and high-performance audio ADC (AD converter) and DAC (DA converter) can also be adopted, combined with an audio codec with extremely low latency, to achieve high-fidelity digital audio transmission. The delay from the microphone transmitting audio to the receiver is within 3 ms, which is applied to vocal music, stage performances and teaching systems. The complete integration from radio frequency to baseband is achieved on a single chip. At the same time, the compander is omitted, and the PCB size can be significantly reduced, the production reliability can be improved, and thus the system cost can be reduced.
[0037] As Figure 3 and Figure 4 shown, in one embodiment, an adjustable wireless microphone provided by the present invention has a spiral groove 110 opened on the surface of the microphone body; the microphone further includes an annular grip 600 and a driving device. A part of the annular grip 600 is wound in the spiral groove 110, and the other part passes through the microphone body and is located inside the microphone body; the driving device is located inside the microphone body and is used to drive the annular grip 600 so that the part of the annular grip 600 located in the spiral groove 110 and the part of the annular grip 600 located inside the microphone body exchange positions.
[0038] Specifically, since the microphones are mostly used in public places, after long-term use, various sweat stains and dirt are inevitably stained on the surface. Considering hygiene and usage comfort, an annular grip 600 is wound around the outer surface and the inner surface of the microphone body, and a driving device for driving the annular grip 600 is arranged inside the microphone body, so that the annular grip 600 located on the outer surface and the inner surface of the microphone body can exchange positions with each other, thereby moving the clean part of the annular grip 600 to the outer surface of the microphone body, and the dirty part of the annular grip 600 is moved to the inner surface of the microphone body, so as to keep the holding part of the microphone clean and tidy.
[0039] In one embodiment, for an adjustable wireless microphone provided by the present invention, a spiral groove 110 is opened on the outer surface of the housing 100, and connection ports 120 penetrating through to the inside of the housing 100 are also opened at both ends of the spiral groove 110, and the annular grip 600 surrounds the inner surface and the outer surface of the housing 100 through the two connection ports 120 respectively.
[0040] Specifically, in order to facilitate installation and positioning of the annular grip 600, a spiral groove 110 is opened on the outer surface of the housing 100, and there is a gap between multiple layers of spirals of the spiral groove 110, so that the annular grip 600 can stably fit in the corresponding position, such as in the spiral groove 110, when being driven by the driving device to move along a preset route.
[0041] In one embodiment, for an adjustable wireless microphone provided by the present invention, a plurality of through grooves 130 are opened on the inner surface of the housing 100, one end of each through groove 130 penetrates through the bottom of the housing 100, the plurality of through grooves 130 are spaced apart around the axis of the housing 100, a clamping member 700 is inserted into the through groove 130, the clamping member 700 protrudes from the inner surface of the housing 100, a part of the annular grip 600 surrounding the inner surface of the housing 100 is inserted into the clamping member 700, and one surface of the annular grip 600 abuts against the clamping member 700.
[0042] Specifically, since the driving device is installed inside the housing 100, a part of the annular grip strap 600 is wound around the outer surface of the housing 100 and a part is located on the inner surface of the housing 100. Therefore, in the absence of interference from other components, the part of the annular grip strap 600 located on the outer surface of the housing 100 will tightly fit into the spiral groove 110, and the part of the annular grip strap 600 located on the inner surface of the housing 100 will be tightened away from the inner surface of the housing 100. To avoid the annular grip strap 600 affecting the internal space layout of the housing 100 and for cleaning the annular grip strap 600, a plurality of through grooves 130 are circumferentially formed on the inner surface of the housing 100. Since one end of the through groove 130 penetrates the bottom of the housing 100, the clamping member 700 can be inserted and installed from the bottom of the housing 100. Subsequently, the annular grip strap 600 is passed through the clamping member 700, and the annular grip strap 600 is limited by a plurality of clamping members 700 located on the inner surface of the housing 100, avoiding the annular grip strap 600 affecting the internal space of the housing 100, and also enabling the annular grip strap 600 to scrape the oil stains and dirt on its surface onto the clamping member 700 during movement. When cleaning is required, the clamping member 700 can be directly pulled out and cleaned.
[0043] In one embodiment, for the adjustable wireless microphone provided by the present invention, the bottom width of the through groove 130 is smaller than the opening width. The clamping member 700 includes a connecting portion 710 and two diagonal bracing portions 720. The two diagonal bracing portions 720 are connected by the connecting portion 710, and there is an angle between the two diagonal bracing portions 720 facing away from the connecting portion 710, and a clamping space 730 is formed among the three.
[0044] Specifically, since the clamping member 700 needs to provide a restraining force to the annular grip strap 600, and the part of the annular grip strap 600 located inside the housing 100 always has a force towards the axis of the housing 100, it is necessary to make the clamping member 700 have a force in the same direction as the radial force of the housing 100 with respect to the through groove 130, so as to ensure that the clamping member 700 can remain stable when receiving the force applied by the annular grip strap 600 towards the axis of the housing 100. At the same time, for the convenience of installation and removal of the clamping member 700 and based on the simplification of the structure, in this embodiment, the size of the through groove 130 is limited, so that on the one hand, the clamping member 700 can be quickly disassembled and assembled, and on the other hand, the clamping member 700 can remain stable under the force applied by the annular grip strap 600.
[0045] As Figure 5 shown, in one embodiment, for the adjustable wireless microphone provided by the present invention, a through opening 740 is formed on one side of the diagonal bracing portion 720 connecting the connecting portion 710. The annular grip strap 600 sequentially passes through a through opening 740, the clamping space 730, and another through opening 740, and abuts against the corner of the connecting portion 710.
[0046] Specifically, a plurality of through openings 740 are spaced apart along the length direction of the clamping member 700, and each through opening 740 corresponds to one layer of the annular grip band 600 arranged in a spiral shape.
[0047] In one embodiment, for an adjustable wireless microphone provided by the present invention, a top contact member 800 is arranged on one side of the connecting portion 710 located in the clamping space 730. The top contact member 800 abuts against one side of the annular grip band 600 passing through the clamping space 730, and a corner of the connecting portion 710 located in the through opening 740 is provided with a rounded corner or an inclined surface.
[0048] Specifically, if the annular grip band 600 abuts against the corner of the connecting portion 710 at the through opening 740, when the clamping member 700 is taken out, the user is likely to touch the dirt at the edge of the through opening 740 of the clamping member 700. In this embodiment, the corner of the connecting portion 710 at the through opening 740 is provided with a rounded corner or an inclined surface to provide a spaced space for the annular grip band 600. Then, a top contact member 800 is arranged on one side of the connecting portion 710 located in the clamping space 730 for abutting against the annular grip band 600. The combination of the two can make the annular grip band 600 have a space from the edge of the through opening 740, preventing dirt from contaminating the edge of the clamping member 700 and making it cleaner and more hygienic to use.
[0049] As Figure 6 shown, in one embodiment, for an adjustable wireless microphone provided by the present invention, the top contact member 800 includes a first top block 810 located in the middle of the clamping member 700, a second top block 820 located on one side of the clamping member 700, and a third top block 830 located on the other side of the clamping member 700. A first offset groove 840 is opened on one side of the top of the second top block 820 close to a diagonal support portion 720, a second offset groove 850 is opened on one side of the top of the third top block 830 close to the other diagonal support portion 720, and the first offset groove 840 and the second offset groove 850 are respectively opened on the first top block 810.
[0050] Specifically, during actual use, the annular grip band 600 may move in a first direction or a second direction. Here, the first direction and the second direction are two opposite directions driven by the driving device. When the annular grip band 600 moves in the first direction, as Figure 6 shown from left to right in, the annular grip band 600 will abut against the top of the second top block 820, and the first offset groove 840 opened on the top of the second top block 820 is used to remove the dirt on the surface of the annular grip band 600 when the annular grip band 600 moves in the first direction. Vice versa. During this process, the dirt scraped by the offset groove will accumulate in the offset groove, and when there is too much dirt in the offset groove, it will move in the direction away from the top of the top block, so as to ensure the best storage capacity of the offset groove and eliminate the need for cleaning personnel to frequently clean the dirt.
[0051] As Figure 7As shown, in one embodiment, for an adjustable wireless microphone provided by the present invention, the top contact member 800 further includes a positioning plate 860. The first top block 810, the second top block 820, and the third top block 830 are all fixed on the positioning plate 860. One side of the positioning plate 860 is attached to the side where the connecting portion 710 is connected to the diagonal support portion 720.
[0052] Specifically, the first top block 810, the second top block 820, and the third top block 830 are arranged on the positioning plate 860. By using the positioning plate 860 to separate the top block for scraping dirt from the engaging member 700 for being engaged in the through groove 130, it can be ensured that the engaging member 700 in contact with the microphone housing 100 always remains clean and tidy. Since both ends of the positioning plate 860 need to be inserted into the through openings 740, the positioning plate 860 needs to be made of an elastic material plate. During installation, first bend the positioning plate 860 so that the width of the bent positioning plate 860 is less than the width between the two diagonal support portions 720. After moving the positioning plate 860 to a suitable position, stop bending the positioning plate 860, so that both ends of the positioning plate 860 stretch and are engaged in the corresponding through openings 740.
[0053] In one embodiment, for an adjustable wireless microphone provided by the present invention, inclined plates 870 are respectively arranged on both sides of the positioning plate 860. One side of the inclined plate 870 is connected to the side edge of the positioning plate 860, and the other side of the inclined plate 870 is inclined towards the direction away from the connecting portion 710.
[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0055] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent of the present invention should be subject to the appended claims.
