Description

Technical Field

[0001] The utility model relates to the technical field of microphones, in particular to a direct-plug USB microphone. Background Art

[0002] Currently, microphones on the market typically connect via USB cables or wirelessly (Bluetooth). Cable connections require users to prepare a separate cable or come with one, making them inconvenient to store. Wireless connections can be unstable in areas with poor signal conditions. Furthermore, current microphones suffer from unrealistic vocal reproduction, low volume, and inability to reduce noise. Utility Model Content

[0003] The utility model provides a direct-plug USB microphone, which can be directly plugged into a computer through a USB connector for use, and can simultaneously achieve long-distance sound reception, voice restoration, and volume enhancement.

[0004] The technical solution adopted by the present invention is: a plug-in USB microphone, including a shell, a circuit control board installed inside the shell, a microphone head located inside the shell is connected to the circuit control board, a USB connector is connected to one side of the circuit control board, and the USB connector is located on one side of the shell.

[0005] As a further improvement of the present invention, a sound receiving hole is provided on the housing at one side of the microphone head.

[0006] As a further improvement of the present invention, the circuit control board is composed of an audio DSP chip, an audio algorithm processing module, and an Audio to USB driver module.

[0007] Beneficial effects of the present invention: The direct-plug USB microphone of the present invention eliminates the data cable required by the traditional microphone. The user only needs to plug the microphone directly into the USB port of the computer to use it, which greatly simplifies the operation process and improves the convenience of use. At the same time, it also avoids the clutter of data cables and is easy to store and carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The terms "up", "down", "left", "right", "front", "back", "front", "back", "top", "bottom" and other directional terms mentioned or possibly mentioned in this specification are defined relative to the structure of the device and are relative concepts. Therefore, they may vary depending on the location and usage of the device; therefore, these or other directional terms should not be interpreted as restrictive.

[0014] As used in this specification, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and implementation methods. It should be understood that the implementation methods described herein are only used to explain this application and are not intended to limit this application.

[0016] The utility model provides the following Figure 1-4 The shown inset is a plug-in USB microphone, comprising a shell 1, a circuit control board 2 installed inside the shell 1, a microphone head 3 located inside the shell 1 connected to the circuit control board 2, a USB connector 4 connected to one side of the circuit control board 2 and located on one side of the shell 1.

[0017] like Figure 2 and Figure 3 As shown, a sound receiving hole 101 is provided on the housing 1 of the present invention at one side of the microphone head 3 .

[0018] like Figure 4 As shown, the circuit control board 2 of the present invention is composed of an audio DSP chip 201 , an audio algorithm processing module 202 , and an Audio to USB driver module 203 .

[0019] Working Principle: During implementation, when a user plugs a USB microphone into a computer's USB port, the audio DSP chip 201 quickly activates and processes the sound signal collected by the microphone head 3 via the audio algorithm processing module 202. This processing includes amplification, noise reduction, and sound quality optimization to ensure a realistic and full-bodied sound. The processed audio signal is then converted to a digital signal via the Audio to USB driver module 203 and directly transmitted to the computer for further processing or storage.

[0020] At the same time, the direct plug-in design eliminates the need for users to prepare additional data cables for the microphone, which not only simplifies the operation steps but also avoids the tangling and clutter of data cables. At the same time, the provision of a sound receiving hole 101 enables the microphone to receive sound from a long distance, further enhancing its convenience and flexibility.

[0021] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
