DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-6 A news interview audio and video recording sound pickup and mixing auxiliary device comprises a sound pickup and mixing auxiliary device 1 and a body 2, wherein the sound pickup and mixing auxiliary device 1 is installed on the top of the body 2; wherein the sound pickup and mixing auxiliary device 1 comprises an external protective cover 3, an intermediate filter cover 4 and an internal fairing 5, wherein the external protective cover 3 is located outside the intermediate filter cover 4, the intermediate filter cover 4 is located outside the internal fairing 5, the internal fairing 5 is connected to the body 2, and a certain space is left between the external protective cover 3, the intermediate filter cover 4 and the internal fairing 5 to form an accommodating space.

[0029] It should be noted that the external protective cover 3, the intermediate filter cover 4 and the internal fairing 5 are all arranged in an inverted cone shape. The external protective cover 3 includes a first cone bottom surface 6, a first cone top surface 7 and a first cone side wall 8. The intermediate filter cover 4 includes a second cone bottom surface 9, a second cone top surface 10 and a second cone side wall 11; the internal fairing 5 includes a third cone bottom surface 12, a third cone top surface 13 and a third cone side wall 14.

[0030] It should be noted that the first cone bottom surface 6, the second cone bottom surface 9 and the third cone bottom surface 12 are central circular blank areas for connecting the body, and the three bottom surfaces are arranged in a superimposed manner. The first cone top surface 7, the second cone top surface 10 and the third cone top surface 13 are designed as a mesh for air outlet and air intake; the first cone side wall 8 is connected between the first cone bottom surface 6 and the first cone top surface 7, the second cone side wall 11 is connected between the second cone bottom surface 9 and the second cone top surface 10, and the third cone side wall 14 is connected between the third cone bottom surface 12 and the third cone top surface 13.

[0031] It should be noted that the first cone side wall 8 is provided with a first arcuate arch frame 801 and a first connecting piece 802. The first arcuate arch frame 801 extends upward from the bottom surface 6 of the first cone to the top 7 of the first cone. The first arcuate arch frames 801 are arranged at equal intervals. The first connecting piece 802 is arranged between every two first arcuate arch frames 801. The first connecting piece 802 is arranged upward layer by layer in the form of stairs. Every two layers are facing each other and are provided with a certain inclination angle to form a sound collection port 803, which is conducive to maximizing the sound collection.

[0032] When people speak, the airflow enters through the sound collecting port 803 on the external protective cover 3 at a certain inclination angle, and passes through the multi-level honeycomb hollow structure stacked by the first arc-shaped arch frame 801 and the first connecting piece 802, the second arc-shaped arch frame 1101 and the second connecting piece 1102 installed on the middle filter cover 4 and the external protective cover 3. The airflow transmission path is reasonably planned to guide and buffer the incoming airflow, avoid the airflow directly acting on the diaphragm and causing noise, and improve the sound pickup quality of the microphone.

[0033] The second cone side wall 11 is provided with a second arc-shaped arch frame 1101 and a second connecting piece 1102. The second arc-shaped arch frame 1101 extends upward from the second cone bottom surface 9 to the second cone top surface 10. The second arc-shaped arch frames 1101 are arranged at equal intervals. The second connecting piece 1102 is arranged between every two second arc-shaped arch frames 1101. The second connecting pieces 1102 are arranged upward layer by layer in the shape of stairs, and each layer is arranged in parallel to form a sound transmission port 1103. The sound airflow enters the sound transmission port 1103 from the external protective cover 3, and the sound transmission port 1103 transmits the sound airflow in parallel to the internal fairing 5, thereby playing a role in parallel transmission of the sound airflow.

[0034] The third cone side wall 14 is provided with a third arc-shaped arch frame 1401 and a third connecting piece 1402. The third arc-shaped arch frame 1401 extends upward from the third cone bottom surface 12 to the third cone top surface 13. The third arc-shaped arch frames 1401 are arranged at equal intervals. The third connecting piece 1402 is arranged between every two third arc-shaped arch frames 1401. The third connecting piece 1402 is arranged horizontally and arranged upward layer by layer in the shape of stairs. The openings between every two layers are opposite to each other, forming a sound diffusion opening 1403, which is conducive to the diffusion of sound.

[0035] When the sound diffuses outward through the microphone or mic, it passes through the sound diffusion port 1403 on the internal fairing 5 and diffuses at a certain angle. This angle setting can diffuse the generated sound outward to the greatest extent. The sound diffusion port 1403 is connected to the second arc-shaped arch frame 1101 and the second connecting piece 1102 installed on the middle filter cover 4 and the external protective cover 3, and the multi-layer honeycomb hollow structure stacked by the first arc-shaped arch frame 801 and the first connecting piece 802 can timely adjust the sound propagation path, reduce sound reflection and reverberation, so that the sound can be better propagated and diffused, and the sound amplification quality is improved.

[0036] It should be noted that the sound transmission port 1103 is connected to the sound collection port 803, and the sound diffusion port 1403 is connected to the sound transmission port 1103, so as to make the external protective cover 3, the middle filter cover 4 and the internal fairing 5 form a multi-layer overlapping honeycomb hollow structure to reduce sound reflection and reverberation.

[0037] During the speaking process, most of the airflow generated by speaking passes through the outer protective cover 3 from the sound collecting port 803. Since the opening of the sound collecting port 803 located on the outer side of the outer protective cover 3 is larger than the opening located on the inner side of the outer protective cover 3, the gas gathers to the outer side of the sound transmission port 803 located on the middle filter cover 4, and then the gas is guided by the sound transmission port 1103 and guided out from the sound transmission port 1103 located on the inner side of the middle filter cover 4 to enter the sound diffusion port 1403; the opening of the sound diffusion port 1403 located on the outer side of the inner fairing 5 is smaller than the opening located on the inner side of the inner fairing port 5, so that it is convenient for the sound diffusion port 1403 to guide the airflow and guide it to the outside of the outer protective cover 3 through the sound transmission port 1103. On the other hand, the opening of the sound collecting port 803 located on the outer side of the outer protective cover 3 is larger than the opening on the inner side thereof, and the opening of the sound diffusion port 1403 located on the inner side of the inner fairing 5 is smaller than the opening on the outer side thereof, so that when people speak, more gas enters and more airflow is guided out.

[0038] It should be noted that the first arc-shaped arch frame 801, the second arc-shaped arch frame 1101, and the third arc-shaped arch frame 1401 are all arranged in a spiral shape, and the positions are arranged to be relative to each other up and down, and the projections overlap. The arc-shaped setting can increase the length of the sound transmission path, thereby better guiding the airflow transmission, and helping to improve the efficiency of sound collection and transmission. The spiral shape is also conducive to eliminating some noise and murmurs, and improving the clarity and purity of the sound. The multi-layer arc-shaped arch frames are arranged relatively up and down to form a multi-layer honeycomb hollow structure, which is more conducive to noise absorption.

[0039] It should be noted that the external protective cover 3 is also provided with a fixing cylinder pin for fixing the external protective cover 3, the intermediate filter cover 4 and the internal fairing cover 5. The external protective cover 3 also has a protective function.

[0040] It should be noted that a sound-absorbing material is provided between the outer protective cover 3 and the middle filter cover 4. The sound-absorbing material is not limited to high-density foam or fiberboard, and is used to absorb unnecessary background noise. The sound-absorbing material can also reduce the echo and reverberation inside the accommodation space, and avoid excessive reflection of the sound inside, thereby ensuring that the collected sound is more real and clear.

[0041] It should be noted that the manufacturing material of the sound pickup and mixing auxiliary device is not limited to plastic or metal.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
