Description

Technical Field

[0001] This utility model relates to a recording microphone. Background Technology

[0002] Existing recording microphones, in high-sensitivity pickup scenarios, are highly susceptible to interference from external mechanical vibrations from stands, desktops, connecting cables, etc. This results in low-frequency noise or a "humming" sound in the recorded audio signal, masking the clarity and detail of the sound, reducing the signal-to-noise ratio, and degrading the recording quality. Post-production requires painstaking effort to remove this noise, which may damage the original sound quality; especially for condenser microphones, prolonged and intense vibrations can even damage their delicate internal diaphragms and electronic components.

[0003] Although existing recording microphones have a single layer of rubber pads at the bracket connection, their shock absorption effect is limited and cannot meet the needs of professional recording. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned defects of the prior art and provide a recording microphone with better shock resistance.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A recording microphone includes a mesh head, a microphone head anti-vibration component, a circuit board assembly, a housing assembly, and an anti-vibration bracket assembly. The microphone head anti-vibration component includes a microphone head frame, a microphone head, a microphone head base, and a support post. The microphone head frame has a square portion at its bottom, which is fixed in a square groove in the microphone head base. The microphone head is inserted into the hollow part of the microphone head frame and locked in place. The microphone head base is fixed to the microphone's circuit board assembly by a support post. The microphone head base is made of anti-vibration material. The microphone head base is placed in and fixed to the housing assembly. A mesh head is fitted over the upper part of the microphone head base and fixed thereon. The mesh head is then fixed to the anti-vibration bracket assembly.

[0006] Better still, the shock-absorbing bracket assembly includes a U-shaped frame, shock-absorbing pads, a support cover, washers, nuts, a shock-absorbing sleeve, and a support sleeve. A connecting post is provided at the bottom of the U-shaped frame, which is inserted into the shock-absorbing pads. The first shock-absorbing pad is embedded in the support cover, with its bottom tightly against the top surface of the first shock-absorbing pad. The remaining shock-absorbing pads are then fitted onto the connecting post and locked in place with washers and nuts. The shock-absorbing sleeve is placed over the shock-absorbing pads, and the support sleeve is placed over the shock-absorbing sleeve. The top surface of the shock-absorbing sleeve is against the support cover, and its bottom surface is supported by the support sleeve. The shock-absorbing sleeve is locked in place by the support cover and the support sleeve. This structure effectively reduces mechanical vibrations generated during recording. The shock-absorbing pads and sleeve isolate the U-shaped frame from the lower support cover and support sleeve, as well as the external recording bracket. Mechanical vibrations are absorbed by the shock-absorbing materials of the shock-absorbing pads and sleeves before reaching the microphone.

[0007] Even better, the support cover is threaded to the support sleeve, making it easy to install and remove.

[0008] Even better, a cable clip is installed on the outside of the support sleeve to hold the microphone's connection cable.

[0009] Better still, the housing assembly includes a housing, a wire clamping block, a wire clamping nut, and a connecting wire. The connecting wire passes through the wire clamping block, the housing, and the wire clamping nut respectively. Then, the wire clamping block is fitted into the opening in the housing and the connecting wire is locked in place by the wire clamping nut.

[0010] Better still, the microphone head is placed inside the housing, and the bottom of the microphone head is fixed to the bottom of the housing with screws. The upper part of the microphone head is covered with a mesh head and fixed with screws. The mesh head is provided with screw holes and is fixed to the two sides of the U-shaped frame with nuts.

[0011] Compared with the prior art, the advantages of this utility model are as follows: by using the microphone head holder as a shock-absorbing material and the shock-absorbing structure of the microphone head holder, the rest of the microphone is isolated from the microphone head, so that mechanical vibration is absorbed by the shock-absorbing structure and material of the microphone head holder before it is transmitted to the microphone head. This can effectively reduce the mechanical vibration generated during the recording process and the noise of mechanical vibration to the microphone head. Moreover, it is not easy to vibrate, thereby reducing noise. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a recording microphone includes a mesh head 1, a microphone head anti-vibration assembly 2, a circuit board assembly 3, a housing assembly 4, and an anti-vibration bracket assembly 5.

[0021] like Figure 3 As shown, the microphone head shockproof assembly 2 includes a microphone head frame 21, a microphone head 22, a microphone head base 23, and a support column 24.

[0022] The microphone head frame 21 has a square part 211 at the bottom. The square part 211 is placed in the square groove 231 of the microphone head base 23 and fixed by screws 25. The microphone head 22 is inserted into the hollow of the microphone head frame 21 and locked by screws 25. The microphone head base 23 has a support column 24 and is fixed to the microphone circuit board assembly 3 by fastening screws 27.

[0023] The microphone head 23 is made of shock-absorbing material, such as rubber, which isolates the rest of the microphone from the microphone head 22. Mechanical vibrations are absorbed by the shock-absorbing material of the microphone head 23 before they reach the microphone head 22, effectively reducing mechanical vibrations generated during recording and the noise caused by mechanical vibrations to the microphone head.

[0024] like Figure 4 , 5 As shown in Figures 6 and 7, the shock-absorbing bracket assembly 5 includes a U-shaped frame 51, a shock-absorbing pad 52, a support cover 53, a gasket 54, a nut 55, a shock-absorbing sleeve 56, and a support sleeve 57.

[0025] A connecting post 511 is provided at the bottom 513 of the U-shaped frame 51. The connecting post 511 is inserted into the shock-absorbing pad 52. The first shock-absorbing pad 52 is embedded in the support cover 53. The bottom 513 is close to the top surface of the first shock-absorbing pad 52. The remaining two shock-absorbing pads 52 are then fitted into the connecting post 511 and locked with a washer 4 and a nut 5.

[0026] The shockproof sleeve 56 is fitted over the shockproof pad 52, and the support sleeve 57 is fitted over the shockproof sleeve 56. The top surface of the shockproof sleeve 56 is attached to the support cover 53, and the bottom surface is supported by the support sleeve 57. The shockproof sleeve 56 is locked by the internal thread of the support cover 53 and the external thread of the support sleeve 57.

[0027] The above structure can effectively reduce mechanical vibrations generated during recording. The U-shaped frame 51, the lower support cover 53 and support sleeve 57, and the external recording bracket are isolated by the shock-absorbing pad 52 and shock-absorbing sleeve 56. Mechanical vibrations are absorbed by the shock-absorbing material of the shock-absorbing pad 52 and shock-absorbing sleeve 56 before they are transmitted to the microphone.

[0028] A wire clip 58 is also provided on the outside of the support sleeve 57. The wire clip 58 on the support sleeve 57 can clamp the connecting wire 44 extending from the microphone to prevent the vibration of the connecting wire 44 from interfering with the microphone.

[0029] like Figure 7 As shown, the housing assembly 4 includes a housing 41, a wire clamping block 42, a wire clamping nut 43, and a connecting wire 44.

[0030] The connecting wire 44 passes through the wire clamping block 42, the housing 41, and the wire clamping nut 43 respectively. Then, the wire clamping block 42 is put into the opening of the housing 41 and locked with the wire clamping nut 43 to lock the connecting wire 44. This structure can fix the wires led out from the microphone circuit board assembly 3 and reduce the vibration interference of jitter on the microphone.

[0031] like Figure 1 , 2 As shown, the microphone head 23 is placed in the housing 41, and the bottom of the microphone head 23 is fixed to the bottom of the housing 41 by screws. The upper part of the microphone head 23 is covered with a mesh head 1 and fixed by screws. The mesh head 1 is provided with screw holes 11, and the mesh head 1 is fixed to the two sides of the U-shaped frame 51 by nuts 512.

[0032] The aforementioned recording microphone employs a four-stage shock absorption structure consisting of a microphone head anti-vibration component, a circuit board component, a housing component, and an anti-vibration bracket component. This systematically isolates external vibrations and cable jitter, significantly improving the recording signal-to-noise ratio.
