Description

Technical Field

[0001] This utility model relates to a desktop microphone, and more particularly to a desktop microphone that can be connected to an external camera, and is applied in the field of microphone technology. Background Technology

[0002] In video content creation (such as video blogs, podcasts, professional reviews, and interview recordings), creators generally pursue high-quality audio-visual effects. Currently, the mainstream audio and video recording solution is the "camera video + computer audio" recording mode. Creators use professional cameras (such as mirrorless cameras and DSLRs) to acquire high-quality video footage, and at the same time, to obtain more professional audio, they use a separate USB / XLR microphone (such as a large condenser microphone) connected to the computer, and record the audio through digital audio workstation (DAW) software. This recording solution requires cumbersome post-production compositing and has significant drawbacks, especially for desktop microphones: First, video and audio are recorded on two different devices (camera and computer). During post-production, the audio track and video track must be synchronized manually by aligning timecode or waveforms. This process is extremely time-consuming, labor-intensive, inefficient, and requires a high level of expertise from the editor. Second, this solution requires the camera, computer, microphone, and various connecting cables to work simultaneously, making setup complex and inconvenient for moving or outdoor shooting, greatly limiting the creative scenarios. Third, without strict timecode system support, relying solely on manual alignment may result in slight errors in audio-visual synchronization, affecting the quality of the final product.

Detailed Implementation

[0020] 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.

[0021] When shooting video podcasts, professionals typically use cameras with high-quality video recording capabilities so that the audio signal can be transmitted to the camera via the camera receiver 20. In existing technology, a desktop microphone cannot directly output to the camera; generally, the camera records video while the audio is recorded to a computer, requiring post-editing to combine them. This invention integrates a wireless desktop microphone with a camera receiver, allowing users to directly record high-quality video and audio together to the camera.

[0022] Please see Figures 1-4 This utility model provides a desktop microphone that can be connected to an external camera, including a microphone body 10 for acquiring real-time audio signals. Desktop microphones typically use condenser microphones, which have the characteristics of high sensitivity, wide frequency response and low self-noise. A camera receiver 20 is used to connect to a camera and can wirelessly connect with the microphone body 10. The video quality captured by the camera is good and professional.

[0023] The aforementioned structure consists of a "camera + receiver" and a "desktop microphone," eliminating the need to carry and set up a computer. It minimizes the number of connecting cables, significantly improving the system's portability and outdoor working capabilities. It also reduces the risk of malfunctions caused by connecting multiple devices. Furthermore, the camera receiver connects to the camera and can wirelessly connect to the desktop microphone, allowing audio signals from the desktop microphone to be transmitted to the camera via the receiver. Users can directly record high-quality video and audio together without manual pairing, effectively solving the problems of error-prone manual audio and video pairing, complex overall setup, and inconvenience for mobile shooting in existing technologies. This saves significant time and labor costs, improving the system's portability and reliability.

[0024] In this embodiment, the desktop microphone is a wireless desktop microphone. Wireless desktop microphones are more convenient to use, freeing users from the constraints of cables. This allows users to move and adjust their positions more freely during shooting, without being limited by cable length or connection method, thereby obtaining more flexible and diverse shooting angles and effects. It also reduces the risk of equipment damage caused by cable tangling, pulling, etc. Of course, in order to avoid wireless communication failure, the microphone body 10 is provided with a wired interface 12 for user convenience. The bottom of the microphone body 10 also features an XLR connector 13, a power switch 14, and a headphone jack 15. Positioning the wired interface 12, XLR connector 13, power switch 14, and headphone jack 15 at the bottom of the microphone body 10 allows for better concealment, resulting in a cleaner appearance and facilitating cable connection. The multiple interfaces also provide users with more operational options and functional expansion. For example, connecting an XLR sound card allows the microphone body 10 to output audio signals to the sound card. The wired interface 12 can be used to connect other audio devices or transmit audio signals. Preferably, the wired interface 12 is a USB-C interface for charging the microphone body 10 and for wired connection to devices, using the microphone body 10 as an audio input device. The headphone jack 15 allows insertion of TRS or TRRS mobile phone headphones, music headphones, or monitoring headphones for monitoring the microphone body 10 or computer playback. The power switch 14 controls the microphone body 10's on / off state for user convenience.

[0025] In this embodiment, the microphone body 10 is provided with a button 16 and a knob 17 on its side wall. The button 16 and knob 17 are provided on the side wall of the microphone body 10 to facilitate the user to adjust the microphone's volume, gain and other parameters to meet the usage needs in 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.

[0026] In this embodiment, the camera receiver 20 is provided with a round hole interface 201 for connecting the camera to the transmission line. Preferably, a 3.5mm audio interface, such as a TRS interface, is used so that the audio signal of the microphone body 10 is received by the camera receiver 20 and then transmitted to the camera through the round hole interface 201 via the transmission line. Existing cameras are generally equipped with external round hole interfaces (such as the common 3.5mm audio interface). The camera receiver 20 should be provided with a round hole interface 201, which can be directly adapted to most mainstream camera models without the need for additional adapters or special connecting cables. This avoids the problem of "device idleness" caused by interface incompatibility and can achieve seamless docking with existing cameras without the need for additional modification of the camera or configuration of special interfaces, greatly improving the universality and compatibility of the device.

[0027] In this embodiment, the camera receiver 20 can be fixedly installed at the hot shoe interface of the camera, which facilitates a stable connection with the camera and ensures that it will not loosen or fall off during shooting, thereby ensuring the stability of audio signal transmission.

[0028] In this embodiment, the camera receiver 20 includes a receiver body 21 and a fixing clip 22. The fixing clip 22 is flexibly and movably disposed on the receiver body 21 so that the camera receiver 20 is clamped to the hot shoe interface of the camera by the fixing clip 22. The hot shoe interface is the standard external interface of current mainstream cameras (SLR, mirrorless, professional camcorders, etc.). The fixing clip 22 is designed to clamp the hot shoe interface and can be directly adapted to most camera models without the need for additional fixing accessories for different brands and models of cameras.

[0029] In this embodiment, the fixing clamp 22 includes a clamping plate 221, a connecting shaft 222, and a reset member 223. The back of the receiver body 21 is provided with two oppositely arranged mounting blocks 11. The two mounting blocks 11 are spaced apart and each is provided with mounting holes 111. One end of the clamping plate 221 and the reset member 223 are both connected to the connecting shaft 222, and both ends of the connecting shaft are installed on the two mounting blocks 11 through the mounting holes 111. The reset member 223 abuts against the clamping plate 221. The clamping plate 221 has an original state and a clamping state. When the clamping plate 221 is in the clamping state, the reset member is used to reset the other end of the clamping plate 221 to approach the receiver body 21, forming a bidirectional clamping of the clamping plate and the receiver body on the hot shoe interface. This structure can clamp more stably at the hot shoe interface of the camera. If the fixing failure problem caused by using magnetic attraction or adhesive is used, the camera receiver is easily damaged.

[0030] In this embodiment, the clamping plate 221 has a protrusion 2211 facing the receiver body 21 at one end away from the connecting shaft 222. The receiver body 21 has a receiving groove 211. When the clamping plate 221 is in its original state, the protrusion 2211 is placed in the receiving groove 211. The protrusion 2211 is preferably made of a flexible material, such as plastic or rubber, so that the receiver body 21 is not easily damaged by slippage. When clamped on the camera, it is also not easy to damage the camera. The main function of the protrusion 2211 is to be engaged with the opening of the hot shoe interface of the camera, so that the receiver body 21 is not easily detached from the camera.

[0031] In this embodiment, the reset member 223 includes two torsion springs 2231. One torsion spring 2231 is close to one of the mounting blocks 11, and the other torsion spring 2231 is close to the other mounting block 11, so that the opening and closing of the clamping plate 221 is more stable and the service life is longer. One end of the two torsion springs 2231 is fixedly connected to ensure that the two torsion springs 2231 operate at the same time, further making the opening and closing of the clamping plate 221 more stable.

[0032] In this embodiment, the camera receiver 20 is equipped with a signal indicator light 23, a noise reduction indicator light (not shown in the figure, its position can be set arbitrarily, but it is best placed in a position that is easy for the user to see, such as the front of the camera receiver 20), a power switch / noise reduction button 24, a charging port 25, a channel switching button 26, and a USB-C audio output port 28; the signal indicator light 23 can display the signal connection status or low battery status; the power switch / noise reduction button 24 can be pressed and held for 2.5 seconds to turn the camera receiver 20 on / off, and after turning it on, a short press of the power switch / noise reduction button 24 can switch the noise reduction level. There are four noise reduction levels: Level 1 (weak), Level 2 (medium), Level 3 (strong), and Level 4 (no noise reduction). Pressing the noise reduction switch sequentially adjusts the level. Pressing it again at Level 3 turns noise reduction off. The noise reduction level is indicated by different colors on the indicator lights: orange for Level 1 (weak), green for Level 2 (medium), and red for Level 3 (strong). These colors do not restrict the level. The noise reduction switch effectively reduces ambient noise interference with the audio signal, improving audio transmission quality. When transmitting audio in noisy environments, turning on the noise reduction switch significantly reduces background noise, resulting in clearer and purer received audio. This further enhances the practicality and adaptability of the wireless microphone combination system, meeting users' needs for high-quality audio transmission in different scenarios. The charging port 25 facilitates charging of the camera receiver 20. The channel switching button 26 allows for quick adjustment of the audio output mode, with three modes available: mono, stereo, and safe audio track switching. The USB-C audio output port 28 expands the compatibility range, balancing compatibility and sound quality, and can connect to mobile phones and computers for recording. The multiple interfaces and buttons on the camera receiver 20 improve device compatibility, lower the barrier to entry and cost, eliminating the need for additional investment in equipment replacement or adapter purchases, while also reducing the complexity of device maintenance and management, making it easier for users.

[0033] In this embodiment, the camera receiver 20 is also provided with positive and negative charging contacts 29 for wireless charging with the charging dock, which facilitates the charging of the camera receiver 20.

[0034] In summary, desktop microphones typically use condenser microphones, which are characterized by high sensitivity, wide frequency response, and low self-noise. Combined with the superior video recording quality of cameras, the two deliver high-quality video and audio. Audio is transmitted to the camera via a receiver, simplifying video recording. Users enjoy broadcast-quality audio from a professional desktop microphone while experiencing the "plug-and-play" ease of use, similar to using an on-camera microphone. The system is also quick to set up and achieves native synchronization of audio and video at the capture end. High-quality audio is directly recorded as an audio track into the camera's video file, resulting in a perfectly synchronized audio-visual file without any post-processing alignment, saving significant time and manpower.

[0035] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
