Description

Technical Field

[0002] The noise-canceling microphone can pick up human voices in noisy scenes (such as outdoor interviews).

[0003] Currently, the noise reduction microphone has a sound receiving port. When receiving sound, a mixed sound including human voice and environmental noise enters the sound receiving port at the same time. Then, the processing unit filters the environmental noise in the mixed sound through an algorithm to achieve noise reduction.

In order to ensure the depth of noise reduction, part of the human voice will inevitably be filtered out, resulting in poor sound quality after receiving the sound. Utility Model Content

[0063] Nowadays, live broadcast and short video have become a mainstream way of video presentation. Among them, outdoor live broadcast and outdoor interviews are common scenes for live broadcast and short video respectively. Because the outdoor scene is relatively noisy, it is necessary to remove environmental noise when using a microphone to collect sound in order to enhance the viewing experience of live broadcast and video. At present, you can choose to use a noise reduction microphone to complete the sound collection and remove environmental noise. The noise reduction microphone has a sound collection port. When collecting sound, a mixed sound containing human voice and environmental noise enters the sound collection port at the same time. Then, the processing unit filters the environmental noise in the mixed sound through an algorithm to achieve noise reduction. However, since the human voice and environmental noise are mixed together and enter the sound collection port, when filtering the environmental noise, part of the human voice will inevitably be filtered out together, resulting in poor sound quality after collection.

[0064] An embodiment of the present disclosure provides a noise reduction microphone, which includes a microphone body 1 , a first sound receiving component 2 , a second sound receiving component 3 and a processing unit 4 .

[0065] The microphone body 1 has a first sound receiving port 11 and a second sound receiving port 12, and there is an angle between the orientation of the first sound receiving port 11 and the orientation of the second sound receiving port 12. The first sound receiving component 2 is located in the microphone body 1 and arranged opposite to the first sound receiving port 11. The second sound receiving component 3 is located in the microphone body 1 and arranged opposite to the second sound receiving port 12. The processing unit 4 is electrically connected to the first sound receiving component 2 and the second sound receiving component 3, respectively.

[0066] In this way, the orientation of the first sound receiving port 11 can correspond to the direction of human voice, the first sound receiving component 2 is used to receive human voice, the orientation of the second sound receiving port 12 can correspond to the environmental noise, and the second sound receiving component 3 is used to receive environmental noise. Thus, the processing unit 4 can collect two audio signals, and the audio signal collected by the second sound receiving component 3 can be used as the reference audio. After algorithm processing, the reference audio is subtracted from the audio signal collected by the first sound receiving component 2 to filter out the environmental noise. In addition, due to the presence of the reference audio, the filtering of human voice can be minimized, thereby improving the quality of human voice after receiving the sound.

[0067] Below, the various components of the noise reduction microphone are introduced separately:

[0068] 1. Microphone body 1

[0069] See also Figure 1 The microphone body 1 has a first sound receiving port 11 and a second sound receiving port 12 , and there is an angle between the first sound receiving port 11 and the second sound receiving port 12 .

[0070] In implementation, the direction of the first sound receiving port 11 may correspond to the direction of human voice, and human voice enters the noise reduction microphone through the first sound receiving port 11. The direction of the second sound receiving port 12 may correspond to the ambient noise, and the ambient noise enters the noise reduction microphone through the second sound receiving port 12.

[0071] In some possible embodiments, the microphone body 1 includes a housing 110 and a printed circuit board 120 .

[0072] like Figure 2 As shown, the housing 110 has a first sound receiving port 11 and a second sound receiving port 12. The printed circuit board 120 is located in the housing 110 and connected to the housing 110.

[0073] refer to Figure 2 The housing 110 may include a first housing piece and a second housing piece, the first housing piece and the second housing piece are arranged to form a receiving space, and the receiving space is used to receive the first sound receiving component 2, the second sound receiving component 3, the processing unit 4 and the printed circuit board 120.

[0074] In one example, the first shell piece has a connecting column, the outer wall of the connecting column is provided with an external thread, the printed circuit board 120 has a plurality of positioning holes, the second shell piece has a threaded hole on the side close to the first shell piece, the printed circuit board 120 is mounted on the first shell piece through the positioning hole, and the second shell piece is fixedly connected to the first shell piece through threads.

[0075] The shapes of the positioning holes and the connecting pillars can be various reasonable shapes, such as both circular or both rectangular. The embodiments of the present disclosure do not limit the shapes of the positioning holes and the connecting pillars.

[0076] Optionally, the first sound receiving component 2 , the second sound receiving component 3 and the processing unit 4 may all be electrically connected to the printed circuit board 120 .

[0077] In this way, the first sound receiving component 2 and the processing unit 4, as well as the second sound receiving component 3 and the processing unit 4 can be electrically connected via the printed circuit board 120, thereby reducing the connection cost.

[0078] In one example, the housing 110 has a cylindrical structure.

[0079] like Figure 2 As shown, the first sound receiving port 11 is oriented perpendicular to the axis of the housing 110 , and the second sound receiving port 12 is oriented parallel to the axis of the housing 110 .

[0080] Optionally, the first sound receiving port 11 may be disposed on the top of the housing 110 .

[0081] In this way, the direction of the first sound receiving port 11 can correspond to the direction of human voice, and human voice enters the noise reduction microphone through the first sound receiving port 11. The direction of the second sound receiving port 12 can correspond to the ambient noise, and the ambient noise enters the noise reduction microphone through the second sound receiving port 12.

[0082] In one example, the housing 110 includes a housing body 1101 and a fixing frame 1102 .

[0083] like Figure 3 As shown, the shell body 1101 has a cylindrical structure, and a second sound receiving port 12 is provided on the top wall of the shell body 1101 , that is, the direction of the second sound receiving port 12 is parallel to the axis of the shell body 1101 , and a receiving through hole 1101a is provided on the side wall of the shell body 1101 .

[0084] refer to Figure 3 The shell body 1101 has a plurality of connection posts 1101 b inside, and the fixing frame 1102 has through holes (not shown) that match the connection posts 1101 b.

[0085] In implementation, the fixing frame 1102 is disposed inside the shell body 1101 , and the fixing frame 1102 is sleeved on the connecting column 1101 b using a through hole to achieve connection with the shell body 1101 .

[0086] In this way, the fixing frame 1102 can fix the first sound receiving component 2 and improve the overall sealing performance of the noise reduction microphone.

[0087] The connecting column 1101b and the shell body 1101 can be formed as one piece, or can be connected together after being processed in steps, which is not limited in the embodiment of the present disclosure.

[0088] like Figure 3 As shown, the fixing frame 1102 is disposed inside the shell body 1101 and arranged opposite to the accommodating through hole 1101 a. The fixing frame 1102 has a first sound receiving opening 11 , and the direction of the first sound receiving opening 11 is perpendicular to the axis of the shell body 1101 .

[0089] like Figure 3 As shown, the shell body 1101 has a receiving space, the printed circuit board 120 is located in the receiving space and connected to the shell body 1101, the first sound receiving component 2, the second sound receiving component 3 and the processing unit 4 are also located in the receiving space and integrated on the same side of the printed circuit board 120.

[0090] The material of the shell body 1101 and the material of the fixing frame 1102 can be the same or different. For example, the material of the shell body 1101 and the fixing frame 1102 can both be plastic, or the material of the shell body 1101 can be plastic and the material of the fixing frame 1102 can be stainless steel. The embodiment of the present disclosure does not limit the material of the shell body 1101 and the material of the fixing frame 1102.

[0091] refer to Figure 2 The microphone body 1 also includes a charging port, which is electrically connected to the printed circuit board 120. Figure 3 The microphone body 1 also includes a control component, which includes a switch control and a mute control. The switch control and the mute control are electrically connected to the processing unit 4 through the printed circuit board 120. The microphone pump body 1 also includes a battery (not shown), which is electrically connected to the printed circuit board 120 to provide power for the first sound receiving component 2, the second sound receiving component 3 and the processing unit 4. The battery can be arranged on the other side of the printed circuit board 120, which can improve the space utilization in the noise reduction microphone.

[0092] 2. The first sound receiving component 2 and the second sound receiving component 3

[0093] The first sound receiving element 2 and the second sound receiving element 3 are components in the noise reduction microphone for converting sounds into electrical signals.

[0094] like Figure 1 As shown, the first sound receiving component 2 is located in the microphone body 1 and arranged opposite to the first sound receiving port 11, and the second sound receiving component 3 is located in the microphone body 1 and arranged opposite to the second sound receiving port 12. Both the first sound receiving component 2 and the second sound receiving component 3 are electrically connected to the processing unit 4.

[0095] In practice, sound enters the noise reduction microphone through the sound receiving port in the form of waves, the first sound receiving component 2 and the second sound receiving component 3 respectively receive the corresponding sound waves, convert the vibration signals into electrical signals, and transmit the electrical signals to the processing unit 4.

[0096] In one example, the noise reduction microphone includes a printed circuit board 120, referring to Figure 2 The printed circuit board 120 is located in the housing 110 and connected to the housing 110 . The first sound receiving component 2 and the second sound receiving component 3 are both electrically connected to the printed circuit board 120 .

[0097] In this way, the first sound receiving component 2 and the second sound receiving component 3 can be integrated on the printed circuit board 120, thereby improving the integration level of the product.

[0098] The first sound receiving component 2 and the second sound receiving component 3 may both be sound pickups. The first sound receiving component 2 and the second sound receiving component 3 may both be active sound pickups or passive sound pickups, which is not limited in the embodiment of the present disclosure.

[0099] 3. Processing Unit 4

[0100] The processing unit 4 is a component of the noise reduction microphone for processing the audio signals output by the first sound receiving component 2 and the second sound receiving component 3 .

[0101] like Figure 3 As shown, the processing unit 4 is located in the housing 110 and is electrically connected to the printed circuit board 120 .

[0102] In implementation, the processing unit 4 receives a first audio signal from the first sound receiving component 2 and a second audio signal from the second sound receiving component 3, and uses a preset algorithm to subtract the second audio signal (reference audio signal) from the audio signal collected by the first sound receiving component 2 to filter out ambient noise.

[0103] In this way, due to the existence of the control audio signal, the filtering of the human voice can be minimized, thereby improving the quality of the human voice after recording.

[0104] Below, some optional structural features of noise reduction microphones are introduced:

[0105] Structural feature 1. The noise reduction microphone also includes a dust cover 5.

[0106] like Figure 4 As shown, the shell body 1101 has a cylindrical structure, and a second sound receiving port 12 is provided on the top wall of the shell body 1101, that is, the second sound receiving port 12 is oriented parallel to the axis of the shell body 1101, and a receiving through hole 1101a is provided on the side wall of the shell body 1101. The dust cover 5 is at least partially located in the receiving through hole 1101a, and is located on the side of the fixing frame 1102 away from the printed circuit board 120, and is connected to the shell body 1101.

[0107] Thus, by providing the dust cover 5, it is possible to prevent the rapid airflow from entering the first sound receiving element 2 during sound reception, thereby preventing popping sound. At the same time, the dust cover 5 can also prevent dust from entering the first sound receiving port 11, thereby keeping the first sound receiving port 11 clean.

[0108] The dust cover 5 can be made of various porous materials, such as foam, and the embodiment of the present disclosure does not limit the material of the dust cover.

[0109] Structural feature 2: The noise reduction microphone also includes a fixing part 8.

[0110] like Figure 4 and Figure 5 As shown, the shape of the fixing member 8 matches the shape of the accommodating through hole 1101 a , the fixing member 8 is located in the accommodating through hole 1101 a , and is located on the side of the dust cover 5 away from the fixing frame 1102 , and is connected to the shell body 1101 .

[0111] refer to Figure 5 The fixing member 8 has a plurality of sound transmission holes.

[0112] The material of the fixing member 8 can be plastic or metal, which is not limited in the embodiment of the present disclosure.

[0113] Optionally, the wall surface of the fixing member 8 away from the dust cover 5 can smoothly transition to the side wall of the shell body 1101 .

[0114] In this way, the overall sense of the product can be improved and the user experience can be enhanced.

[0115] Structural feature three: The noise reduction microphone also includes a collar clip component 6.

[0116] During outdoor interviews, it may be inconvenient for users to hold the microphone, so a collar clip assembly 6 can be provided on the noise reduction microphone, and the noise reduction microphone can be clamped and fixed on the collar during the interview, thereby improving convenience.

[0117] like Figure 5 As shown, the noise reduction microphone further includes a collar assembly 6. The collar assembly 6 includes a clamp handle 61 and a torsion spring 62, one end of the clamp handle 61 is rotatably connected to the microphone body 1, and both ends of the torsion spring 62 are respectively connected to one end of the clamp handle 61 and the microphone body 1.

[0118] In an example, a connecting seat may be provided on the wall surface of the microphone body 1 away from the second sound receiving port 12 , and the clamping handle 61 is rotatably connected to the connecting seat.

[0119] Alternatively, if Figure 6 As shown, the other end of the clamping handle 61 has a protruding structure 611 on one side close to the microphone body 1 .

[0120] Exemplarily, there may be a plurality of protruding structures 611 , and one end of the protruding structure 611 close to the microphone body 1 may be in a sawtooth structure.

[0121] In this way, the friction between the other end of the clamping handle 61 and the collar can be increased, thereby improving the stability of the clamping and fixing of the noise reduction microphone.

[0122] Optionally, the collar clip assembly 6 may further include a first magnetic attraction member 63 .

[0123] like Figure 5 As shown, the first magnetic member 63 is located on a side of the clamping handle 61 away from the microphone body 1 , and is connected to the clamping handle 61 .

[0124] The connection method between the first magnetic member 63 and the clamping handle 61 can be bonding or clamping. The embodiment of the present disclosure does not limit the connection method between the first magnetic member 63 and the clamping handle 61.

[0125] In practice, a magnetic component with a different polarity from the first magnetic component 63 can be selected and placed on the inside of the collar, and the noise reduction microphone can be set on the outside of the collar. The noise reduction microphone can be clamped and fixed in place on the collar through the attraction between the first magnetic component 63 and the inner magnetic component.

[0126] This will avoid pinch marks on the collar.

[0127] Structural feature 4: The noise reduction microphone also includes an indicator light 7.

[0128] like Figure 1 As shown, the microphone body 1 has an indicator light accommodating hole 13, the indicator light 7 is located in the indicator light accommodating hole 13, and is electrically connected to the processing unit.

[0129] In implementation, the processing unit 4 is used to control the indicator light 7 to be always on in the first color in the charging state;

[0130] In the mute state, the control indicator light 7 is always on in the second color; in the disconnected state, the control indicator light 7 flashes in the second color. The first color may be green, and the second color may be red.

[0131] In this way, the user can judge the current working status of the noise reduction microphone by the flashing and color of the indicator light 7.

[0132] Structural feature 5: The noise reduction microphone also includes a magnetic charging component 9.

[0133] like Figure 6 As shown, the magnetic charging component 9 is located on a side of the microphone body 1 away from the first sound receiving port 11 and is connected to the microphone body 1 . The magnetic charging component 9 includes a magnetic port 91 and a charging port 92 .

[0134] In practice, the magnetic suction port 91 cooperates with the magnetic suction head in the charging base, and the charging port 92 cooperates with the charging pin in the charging base, and the noise reduction microphone can be placed in the charging base to complete charging.

[0135] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0136] The disclosed embodiment provides a noise reduction microphone, in which a microphone body 1 has a first sound receiving port 11 and a second sound receiving port 12, and an angle exists between the orientation of the first sound receiving port 11 and the orientation of the second sound receiving port 12. A first sound receiving component 2 is located in the microphone body 1, and is arranged opposite to the first sound receiving port 11. A second sound receiving component 3 is located in the microphone body 1, and is arranged opposite to the second sound receiving port 12. The processing unit 4 is electrically connected to the first sound receiving component 2 and the second sound receiving component 3, respectively. In this way, the orientation of the first sound receiving port 11 can correspond to the direction of human voice, and the first sound receiving component 2 is used to receive human voice, and the orientation of the second sound receiving port 12 can correspond to environmental noise, and the second sound receiving component 3 is used to receive environmental noise. Thus, the processing unit 4 can collect two audio signals, and can use the audio signal collected by the second audio receiving component 3 as the reference audio. After algorithm processing, the audio signal collected by the first audio receiving component 2 is subtracted from the reference audio to filter out environmental noise. In addition, due to the existence of the reference audio, the filtering of human voice can be minimized, thereby improving the quality of the human voice after recording.
