Description

Technical Field

[0001] This utility model relates to a microphone assembly, and more particularly to a wireless microphone assembly system, which is applied in the field of microphone technology. Background Technology

[0002] With the rapid development of industries such as live streaming, short videos, and online conferencing, users' demands for audio quality are increasing. Small microphones (especially "one-to-two" models, i.e., one receiver with two transmitters) have become standard equipment in the industry due to their advantages such as freeing up hands, avoiding cable constraints, and improving sound quality. However, existing wireless one-to-two small microphones currently have shortcomings and cannot meet the needs of some user scenarios. For example, while purchasing a single "one-to-two" small microphone set is advantageous in outdoor mobile scenarios due to its portability and concealment, when users return to fixed indoor settings (such as live streaming studios, offices, or broadcasting stations) for seated or fixed-position live streaming, firstly, in a professional indoor environment, continuing to use a small microphone clipped to a collar would appear rudimentary. First, the microphones don't match the professional indoor set design and lighting environment, giving viewers a "not professional" visual impression. Second, small microphones are usually omnidirectional or cardioid, which easily pick up more ambient noise and wall reflections in indoor environments, resulting in decreased sound clarity and a "room reverberation" effect, unlike professional desktop microphones. Third, if users want better sound quality and a professional look indoors, they have to purchase a professional USB / XLR desktop microphone, which means physically switching between two completely independent systems (plugging and unplugging receivers, resetting audio input sources, etc.), which is cumbersome, results in poor live stream continuity, and has a higher overall cost. Utility Model Content

[0003] To address the aforementioned issues that existing small microphones, when used indoors, tend to pick up more ambient noise and wall reflections, leading to decreased sound clarity and a "room reverberation" effect, inferior to professional desktop microphones, and the fact that users seeking better sound quality and a professional viewing experience indoors are forced to purchase a separate professional USB / XLR desktop microphone, resulting in complex physical switching between small and desktop microphones, poor live streaming continuity, and higher overall costs, this invention provides a wireless microphone combination system to solve the above technical problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a wireless microphone combination system, including at least one small mobile microphone for acquiring a real-time first audio signal; at least one wireless indoor microphone for acquiring a real-time second audio signal; and a wireless communication receiver, all of which are wirelessly connected to at least one small mobile microphone and at least one wireless indoor microphone. The wireless communication receiver is used to connect to an external terminal so that the first audio signal is transmitted between at least one small mobile microphone and the external terminal through the wireless communication receiver, and the second audio signal is transmitted between at least one wireless indoor microphone and the external terminal through the wireless communication receiver.

[0005] Furthermore, the small mobile microphone is a wireless lavalier microphone.

[0006] Furthermore, the wireless indoor microphone is a wireless desktop microphone.

[0007] Furthermore, the wireless communication receiver is provided with a plug-in terminal so that the wireless communication receiver can be plugged into the terminal.

[0008] Furthermore, the wireless communication receiver is also provided with a first wired interface, which can be used for connecting a transmission line.

[0009] Furthermore, the wireless communication receiver is also provided with a noise reduction switch for reducing audio noise, and a first noise reduction indicator light for displaying whether the noise reduction switch controls the noise reduction of the small mobile microphone to be turned on, and a second noise reduction indicator light for displaying whether the noise reduction switch controls the noise reduction of the wireless indoor microphone to be turned on.

[0010] Furthermore, the wireless indoor microphone includes a microphone body and a mounting bracket, with the microphone body mounted on the mounting bracket.

[0011] Furthermore, the mounting bracket is a desktop bracket or a cantilever bracket.

[0012] Furthermore, the mounting bracket includes a support base and a support frame that can rotate relative to the support base. The microphone body has an annular groove on its side wall, and the mounting bracket has a corresponding snap-fit ​​protrusion on the annular groove. The snap-fit ​​protrusion is disposed on the support frame. There are at least two snap-fit ​​protrusions, and the two snap-fit ​​protrusions are disposed opposite to each other. When the snap-fit ​​protrusion is snapped into the annular groove, the snap-fit ​​protrusion is locked into the annular groove by a locking member, so that the microphone body is fixedly mounted on the mounting bracket.

[0013] Furthermore, the bottom of the wireless indoor microphone is provided with a second wired interface, an XLR interface, a power switch and an earphone interface, and the side wall of the wireless indoor microphone is provided with buttons and knobs.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a wireless microphone combination system, which combines a wireless indoor microphone and a small mobile microphone into a "one-to-two wireless microphone" by sharing a wireless communication receiver. Users can use the small mobile microphone outdoors and switch directly to the wireless indoor microphone when they return to an indoor environment, achieving seamless switching. This solves the problem of "room reverberation" caused by environmental noise and wall reflections when using the small mobile microphone indoors, which affects users' indoor live streaming. Furthermore, there is no need for physical conversion between the two devices from outdoors to indoors, making live streaming smoother and improving the user experience. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model 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 this utility model and are not intended to limit this utility model.

[0020] Please see Figures 1-3This utility model provides a wireless microphone combination system, including at least one small mobile microphone 10 for acquiring real-time first audio signals. Users can use the small mobile microphone 10 for outdoor live streaming. The small mobile microphone 10 can be a wireless lavalier microphone or a small microphone, preferably a wireless lavalier microphone; at least one wireless indoor microphone 20 for acquiring real-time second audio signals. Users can use the wireless indoor microphone 20 for outdoor live streaming. The wireless indoor microphone 20 can be a wireless desktop microphone, a hanging wireless microphone, or a large microphone. In this embodiment, a wireless desktop microphone is preferred; and a wireless communication receiver 30, which is connected to at least one wireless microphone. A small portable microphone 10 and at least one wireless indoor microphone 20 are wirelessly connected. A wireless communication receiver 30 is used to connect to an external terminal, enabling the first audio signal to be transmitted between at least one of the small portable microphones 10 and the external terminal via the wireless communication receiver 30, and the second audio signal to be transmitted between at least one of the wireless indoor microphones 20 and the external terminal via the wireless communication receiver 30. The "one-to-two" wireless communication receiver configuration is existing technology, and no technical changes are made in this embodiment, so it will not be elaborated further. It is understood that this wireless microphone combination system, by setting up a small portable microphone and a wireless indoor microphone, meets the audio acquisition needs in different scenarios. The small portable microphone is easy to carry and can be used by users in mobile environments such as outdoors to acquire the first audio signal in real time; while the wireless indoor microphone is suitable for fixed locations, such as conference rooms and recording studios, to acquire the second audio signal in real time. The wireless communication receiver, as a core component, enables wireless transmission of audio signals. It can establish wireless communication connections not only with the small mobile microphone and the wireless indoor microphone, but also with external terminals, ensuring smooth transmission of the first and second audio signals between the microphone and the external terminal. Terminals can include, but are not limited to, tablets, laptops, desktop computers, super mobile PCs, netbooks, and mobile phones. Both the small mobile microphone 10 and the wireless indoor microphone 20 are equipped with power switches. When a user moves from indoors to outdoors, they can turn off the small mobile microphone 10 and then turn on the wireless indoor microphone, facilitating wireless switching. In other words, by combining the wireless indoor microphone and the small mobile microphone using a single wireless communication receiver to form a "one-to-two wireless microphone," users can seamlessly switch from using the small mobile microphone outdoors to the wireless indoor microphone upon returning indoors. This solves the problem of "room reverberation" caused by environmental noise and wall reflections when using the small mobile microphone indoors, which affects indoor live streaming. Furthermore, no physical transition is required between the two devices from outdoors to indoors, making live streaming smoother and improving the user experience.

[0021] In this embodiment, the small mobile microphone 10 can be a wireless lavalier microphone. Most small microphones on the market are currently lavalier microphones. While lavalier microphones are convenient for users to use outdoors, they tend to pick up more environmental noise and wall reflections when used indoors, resulting in a decrease in sound clarity and a "room reverberation" effect. Therefore, in this embodiment, the small mobile microphone 10 is preferably a wireless lavalier microphone. By using the same receiver as the wireless indoor microphone 20, the problem of the wireless lavalier microphone being difficult to use indoors is solved for the user.

[0022] In this embodiment, the wireless indoor microphone 20 can be a wireless desktop microphone. The wireless desktop microphone is usually fixed on the desktop, which makes it convenient for users to switch wirelessly when entering the room from the outdoors. Of course, if the user is not sitting and broadcasting, but standing, the microphone body of the wireless desktop microphone can be placed and installed on the cantilever bracket.

[0023] In this embodiment, the wireless communication receiver 30 is provided with a plug-in terminal 31, which allows the wireless communication receiver 30 to be plugged into the terminal. The plug-in terminal 31 can be set as an Apple mobile phone plug-in terminal or a USB-C interface plug-in terminal, or the wireless communication receiver 30 can be set with multiple plug-in terminals, but this is not recommended, because data transmission can also be carried out through the interface and data cable. Therefore, it is preferred to set a single plug-in terminal, but this is not a limitation.

[0024] In this embodiment, the wireless communication receiver 30 is further provided with a first wired interface 32. The first wired interface 32 can be used for connecting transmission lines. The first wired interface 32 provides users with more connection options. For example, when the wireless communication receiver 30 is interfered with or the user needs more stable audio transmission, the wireless communication receiver can be directly connected to an external terminal via a transmission line to ensure stable audio signal transmission. Simultaneously, this interface can also be used to connect other audio devices. The first wired interface 32 can be configured as a USB-A interface or a USB-C interface, preferably a USB-C interface, supporting connection to devices such as mobile phones / tablets / computers / action cameras with USB-C interfaces. The USB-C charging interface supports external chargers, allowing for simultaneous charging and use, which is convenient for users.

[0025] In this embodiment, the wireless communication receiver 30 is also equipped with a noise reduction switch for reducing audio noise. This noise reduction switch effectively reduces interference from ambient noise on the audio signal, improving the quality of audio transmission. When a user is transmitting audio in a noisy environment, turning on the noise reduction switch significantly reduces background noise, making the received audio clearer and purer. This further enhances the practicality and adaptability of the wireless microphone combination system, meeting the user's need for high-quality audio transmission in different scenarios.

[0026] In this embodiment, the wireless communication receiver 30 is further provided with a first noise reduction indicator 110 for displaying whether the noise reduction switch 33 controls the noise reduction of the small mobile microphone 10 to be turned on, and a second noise reduction indicator 120 for displaying whether the noise reduction switch 33 controls the noise reduction of the wireless indoor microphone 20 to be turned on. The setting of the first and second noise reduction indicator lights provides users with intuitive feedback on the noise reduction status; when lit, it is in the on state, and when there is no light, it is in the off state. When the user turns the noise reduction function on or off, the corresponding indicator light will light up or turn off, so that the user can quickly understand the current noise reduction working status of the microphone. Furthermore, setting separate noise reduction indicator lights for the small mobile microphone 10 and the wireless indoor microphone 20 also allows the user to check whether the microphone they want to use has been correctly turned on, providing convenience for the user. That is, the user can flexibly adjust the noise reduction function according to the level of ambient noise and the needs of live streaming to obtain the best audio effect. Of course, the first noise cancellation indicator light 110 and the second noise cancellation indicator light 120 can not only indicate the on and off status, but the noise cancellation switch can also control the degree of noise cancellation. For example, there are four levels of noise cancellation: Level 1 (weak), Level 2 (medium), Level 3 (strong), and Level 4 (no noise cancellation). Pressing the noise cancellation switch in sequence will adjust the level. When you reach Level 3, pressing it again will turn off the noise cancellation. The noise cancellation levels of Level 1 (weak), Level 2 (medium), and Level 3 (strong) can be displayed by different colors on the noise cancellation indicator lights. For example, Level 1 (weak) can be displayed in orange, Level 2 (medium) in green, and Level 3 (strong) in red. There are no restrictions on this. Of course, the noise reduction switch can also be used as the power switch for the wireless communication receiver 30. For example, pressing and holding for 2.5 seconds will turn the power of the wireless communication receiver 30 on / off. When the power of the wireless communication receiver 30 is turned on after pressing and holding for 2.5 seconds, the noise reduction level is the same as when the user turned off the power of the wireless communication receiver 30 last time. Switching the noise reduction level can be achieved by short pressing the noise reduction switch, which is convenient for users. Setting the power of the wireless communication receiver 30 to be turned on / off can extend the service life of the wireless communication receiver 30 and improve the overall user experience.

[0027] In this embodiment, the wireless indoor microphone 20 includes a microphone body 21 and a mounting bracket 22. The microphone body 21 is mounted on the mounting bracket 22, allowing the user to flexibly adjust the angle and height of the mounting bracket 22 according to the needs of the usage scenario.

[0028] In this embodiment, the mounting bracket 22 is a desktop bracket or a cantilever bracket, which is available for the user to choose from and makes it convenient for the user to use.

[0029] In this embodiment, the mounting bracket 22 includes a support base 221 and a support frame 222 that can rotate relative to the support base 221. The microphone body 21 has an annular groove 211 on its side wall. The mounting bracket 22 has a corresponding snap-fit ​​protrusion 223 on the annular groove 211. The snap-fit ​​protrusion 223 is disposed on the support frame 222. There are at least two snap-fit ​​protrusions 223, and the two snap-fit ​​protrusions 223 are disposed opposite to each other. When the snap-fit ​​protrusion 223 is snapped into the annular groove 211, the snap-fit ​​protrusion 223 is locked into the annular groove 211 by the locking member 220. The microphone body 21 is fixedly mounted on the mounting bracket 22 within the groove 211, making the installation and removal of the microphone very simple. The user only needs to align the snap-fit ​​protrusion with the annular groove 211 and press it down gently, and the microphone can be installed by using the locking member 220. When it is necessary to remove the microphone, simply loosen the locking member 220 and remove the snap-fit ​​protrusion from the annular groove. This is convenient for the user. The locking member 220 can be a locking member that can be unscrewed with a tool, a snap-fit ​​locking member, or a hand-tightening locking member. No limitation is made here.

[0030] In this embodiment, the bottom of the wireless indoor microphone 20 is provided with a second wired interface 23, an XLR interface 24, a power switch 25, and a headphone jack 26. The placement of these interfaces at the bottom of the wireless indoor microphone 20 is for better concealment, resulting in a cleaner appearance and facilitating the connection of transmission cables. The multiple interfaces also provide users with more operational options and functional expansion. For example, connecting to an XLR sound card allows the microphone to output audio signals to the sound card. The second wired interface 23 can be used to connect other audio devices or transmit audio signals. Preferably, the second wired interface 23 is a USB-C interface for charging the microphone and for wired connection to devices, using the microphone as an audio input device. The headphone jack allows insertion of TRS or TRRS mobile phone headphones, music or monitoring headphones for monitoring the microphone or computer playback. The power switch controls the wireless indoor microphone's on / off state, facilitating wireless switching with the small mobile microphone 10 and enhancing user convenience.

[0031] In this embodiment, the wireless indoor microphone 20 is provided with a button 27 and a knob 28 on its side wall. The button 27 is located on the side wall of the wireless indoor microphone 20 to facilitate the user to adjust the microphone's volume, gain and other parameters to meet the usage needs of different scenarios. In this embodiment, the button 27 can be a mute button, which is convenient for the user to adjust in real time as needed.
