Description

Technical Field

[0001] This utility model belongs to the field of microphone technology, and in particular relates to a microphone. Background Technology

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. It is widely used in voice recording, broadcasting, live performances, and communications.

[0003] An existing microphone includes a stand and a microphone body. The stand is used to fix the microphone body in a preset position. The microphone body has a sound-receiving structure 3, which faces the user's position. When the user's sound source (mouth) 26 is directly facing the microphone, such as... Figure 1 As shown, a first sector-shaped area is formed with the location of the sound receiving structure 3 as the center and the line connecting the sound receiving structure 3 and the sound source (mouth) 26 as the radius. The sound waves emitted by the sound source 26 will also form a second sector-shaped area with the sound source 26 as the center. The area where the first sector-shaped area and the second sector-shaped area intersect is the optimal sound receiving area 27 of the microphone body.

[0004] However, during microphone use, the user's head does not remain in the same position for an extended period. As the user's head rotates, the sound source (mouth) 26 deflects at a certain angle, and the second sector area also deflects accordingly. Figure 2 As shown, the optimal sound pickup area 27 between the microphone body and the sound source becomes smaller, and the sound pickup effect of the microphone body deteriorates.

[0029] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figures 3 to 5 As shown, an embodiment of this utility model provides a microphone, including a base 6, a driving mechanism 8, and a microphone body 1. The base 6 is provided with a mounting groove 24. The microphone body 1 includes a housing 2 and a sound receiving structure 3. The sound receiving structure 3 is installed in the housing 2. The housing 2 is rotatably assembled in the mounting groove 24. The driving mechanism 8 is connected to the base 6, and the housing 2 is connected to the driving mechanism 8. The driving mechanism 8 is used to drive the housing 2 to rotate so that the sound receiving structure 3 can face the sound source 26.

[0031] Specifically, the drive mechanism 8 is connected to the base 6, and the housing 2 of the microphone body 1 is connected to the drive mechanism 8. The drive mechanism 8 can drive the housing 2 of the microphone body 1 to rotate, thereby causing the sound-receiving structure 3 installed inside the housing 2 to rotate, so that the sound-receiving structure 3 faces the sound source 26, such as... Figure 6 As shown, the range of the optimal sound reception area 27 between the sound source 26 and the sound reception structure 3 can be expanded, thereby improving the sound reception effect of the microphone body 1 when the microphone body 1 rotates.

[0032] In one embodiment, the microphone body 1 further includes an identification mechanism installed in the housing 2, the identification mechanism being used to detect the position of the sound source 26, and the driving mechanism 8 driving the housing 2 to rotate, so that the sound receiving structure 3 always faces the sound source 26.

[0033] Specifically, in this embodiment, the housing 2 is further provided with a first control circuit board 4, and the base 6 is provided with a second control circuit board 9. The identification mechanism is electrically connected to the first control circuit board 4, and the driving mechanism 8 is electrically connected to the second control circuit board. The identification mechanism is a camera 5 installed on the microphone body 1. The camera 5 determines the specific location of the user's sound source 26 and transmits the location information of the sound source 26 to the first control circuit board 4. The first control circuit board 4 then transmits the location information to the second control circuit board 9 in the second base 6. The second control circuit board 9 controls the driving mechanism 8 to rotate the microphone body 1 to a certain angle, such as... Figure 6 As shown, this expands the range of the optimal sound reception area 27 between the sound source 26 and the sound reception structure 3.

[0034] In one embodiment, the driving mechanism 8 includes a driving member 10 and a first driving ring 13. The first driving ring 13 is sleeved on the outer periphery of the housing 2. The driving member 10 is connected between the first driving ring 13 and the base 6 to drive the first driving ring 13 to rotate.

[0035] Specifically, the bottom wall of the mounting groove 24 is provided with a limiting ring groove 25. The end of the first driving ring 13 near the bottom wall of the groove is slidably inserted into the limiting ring groove 25. The driving member 10 drives the first driving ring 13 to rotate in the limiting groove. The first driving ring 13 is sleeved on the outer periphery of the housing 2. When the first driving ring 13 rotates, it can drive the housing 2 to rotate.

[0036] In one embodiment, the driving component 10 includes a motor 11 and a gear 12. The housing of the motor 11 is fixed to the base 6. The gear 12 is connected to the output shaft of the motor 11. The outer peripheral surface of the first driving ring 13 is provided with teeth 14 that mesh with the gear 12.

[0037] Specifically, the base 6 is provided with an installation chamber 7, which is spaced apart from the installation groove 24 and is connected to the installation groove 24. The first control circuit board 4, the motor 11 and the gear 12 are all installed in the installation chamber 7. The motor 11 is electrically connected to the first control circuit board 4. The output shaft of the motor 11 extends vertically. The outer shell of the motor 11 is fixed to the inner wall of the installation chamber 7. The gear 12 is installed on the output shaft of the motor 11. The first drive ring 13 is slidably inserted into the limiting ring groove 25. The outer circumferential surface of the first drive ring 13 is provided with teeth 14, which mesh with the gear 12. The motor 11 drives the gear 12 to drive the first drive ring 13 to rotate. The structure is simple and easy to design.

[0038] In one embodiment, the driving mechanism 8 further includes a second driving ring 18, which is sleeved on the outer periphery of the housing 2, and a second magnetic suction element 19 is provided on the second driving ring 18.

[0039] The first drive ring 13 is rotatably mounted on the base 6. The first drive ring 13 is sleeved on the outer periphery of the second drive ring 18. There is a gap between the inner periphery of the first drive ring 13 and the outer periphery of the second drive ring 18. The first drive ring 13 is provided with a first magnetic attracting member 15. The first magnetic attracting member 15 and the second magnetic attracting member 19 attract each other. The first magnetic attracting member 15 is used to attract the second magnetic attracting member 19 when the first drive ring 13 rotates, so that the second drive ring 18 can follow the first drive ring 13 to rotate.

[0040] Specifically, the second drive ring 18 is fitted inside the housing 2, allowing the housing 2 to rotate with the second drive ring 18. A first magnetic chuck 15 is mounted on the first drive ring 13, and a second magnetic chuck 19 is mounted on the second drive ring 18. The second magnetic chuck 19 has the opposite magnetic properties to the first magnetic chuck 15 and is positioned within the magnetic field generated by the first magnetic chuck 15. The first magnetic chuck 15 is located within the magnetic field generated by the second magnetic chuck 19, and the two magnetic chucks are always attracted to each other. When the first drive ring 13 rotates, the first magnetic chuck 15 on the first drive ring 13 attracts the second magnetic chuck 19 on the second drive ring 18, causing the second magnetic chuck 19 to drive the second drive ring 18 to rotate. The housing 2 is driven to rotate by magnetic force, eliminating the need for a separate mechanical transmission structure, resulting in a simple structure.

[0041] In one embodiment, the first magnetic attractor 15 includes a plurality of first magnets, which are arranged at circumferential intervals along the first drive ring 13. The plurality of first magnets include a plurality of first N-pole magnets 16 and a plurality of first S-pole magnets 17, which are arranged alternately.

[0042] The second magnetic attractor 19 includes a plurality of second magnets, which are arranged at circumferential intervals along the second drive ring 18. The plurality of second magnets include a plurality of second N-pole magnets 21 and a plurality of second S-pole magnets 20, which are arranged alternately.

[0043] The first N-pole magnet 16 and the second S-pole magnet 20 are arranged in a one-to-one correspondence, and the first S-pole magnet 17 and the second N-pole magnet 21 are arranged in a one-to-one correspondence.

[0044] Specifically, the first N-pole magnet 16 and the first S-pole magnet 17 are arranged alternately along the circumference of the first drive ring 13, and the second N-pole magnet 21 and the second S-pole magnet 20 are arranged alternately along the circumference of the second drive ring 18. This arrangement can generate a relatively uniform magnetic field between the first drive ring 13 and the second drive ring 18, so that the magnetic field fills the circumference of the second drive ring 18. This ensures that the second magnetic attractor 19 always generates a magnetic attraction force on the first drive ring 13, enabling the first drive ring 13 to rotate stably.

[0045] In one embodiment, the bottom wall of the mounting groove 24 is provided with a positioning protrusion, and the side of the housing 2 facing the bottom wall of the mounting groove 24 is provided with a groove. The groove is located on the central axis of the microphone body 1. The side of the housing 2 facing the bottom wall of the mounting groove 24 abuts against the bottom wall of the groove, and the positioning protrusion is inserted into the groove.

[0046] Specifically, a positioning protrusion is provided at the center of the bottom wall of the mounting groove 24. The positioning protrusion is concentrically arranged with the second drive ring 18 and the first drive ring 13. A groove is provided at the bottom of the housing 2. The groove is located on the central axis of the housing 2. The positioning protrusion can serve as the rotation center of the microphone body 1 and can also limit the housing 2 to prevent radial shaking and improve the stability of the rotation of the microphone body 1.

[0047] In one embodiment, the drive mechanism 8 further includes a bushing 22 disposed on the housing 2, and the second drive ring 18 is sleeved on the bushing 22.

[0048] Specifically, the inner circumference of the bushing 22 is fixed to the housing 2, and the inner circumference of the second drive ring 18 is sleeved on the outer circumference of the bushing 22. The bushing 22 can separate the magnetic field from the housing 2, so as to prevent the magnetic field from affecting the electrical components inside the housing 2.

[0049] In one embodiment, the side of the second drive ring 18 facing the bushing 22 is interference-fitted with the side of the bushing 22 facing away from the housing 2.

[0050] The driving mechanism 8 also includes a limiting ring plate 23 disposed on the outer periphery of the housing 2, wherein the side of the limiting ring plate 23 facing the bottom wall of the groove abuts against the side of the first driving ring 13 facing away from the bottom wall of the groove.

[0051] Specifically, the limiting ring plate 23 is fixed to the outer circumferential surface of the housing 2, and the second drive ring 18 is detachably interference-fitted with the bushing 22. The lower side of the limiting ring plate 23 abuts against the bushing 22 and the second drive ring 18. The second drive ring 18 is detachably fitted onto the bushing 22 for easy replacement. The limiting ring plate 23 is used to stop the second drive ring 18 and prevent it from detaching from the bushing 22.

[0052] The microphone of this utility model embodiment works on the following principle:

[0053] The camera 5 determines the specific location of the user's sound source 26. When a change in the location of the sound source 26 is detected, the camera 5 transmits the location information of the sound source 26 to the first control circuit board 4. The first control circuit board 4 then activates the second control circuit board 9 located in the second base 6. The second control circuit board 9 controls the motor 11 to start. The motor 11 drives the gear 12 to rotate, causing the gear 12 to drive the first drive ring 13 to rotate. When the first drive ring 13 rotates, the first magnetic attraction 15 on the first drive ring 13 attracts the second magnetic attraction 19 on the second drive ring 18, causing the second magnetic attraction 19 to drive the second drive ring 18 to rotate. The second drive ring 18 then drives the housing 2 of the microphone body 1 to rotate to a certain angle, such as... Figure 6 As shown, this expands the range of the optimal sound reception area 27 between the sound source 26 and the sound reception structure 3.

[0054] According to the present invention, compared with the prior art, the driving mechanism 8 is connected to the base 6, and the housing 2 of the microphone body 1 is connected to the driving mechanism 8. The driving mechanism 8 can drive the housing 2 of the microphone body 1 to rotate, thereby driving the sound receiving structure 3 installed in the housing 2 to rotate, so that the sound receiving structure 3 faces the sound source 26, thereby expanding the range of the optimal sound receiving area 27 between the sound source 26 and the sound receiving structure 3, and thus improving the sound receiving effect of the microphone body 1 when the microphone body 1 rotates.

[0055] In other embodiments, the driving command for the driving mechanism 8 can be issued by a remote control. When the user turns their head and finds that the microphone's sound reception effect has deteriorated, the remote control can be used to control the driving mechanism 8 to rotate the microphone housing 2 back and forth, adjusting the direction of the sound receiving structure 3 inside the housing 2, so that the microphone body 1 can obtain the best sound reception effect.

[0056] In other embodiments, the identification mechanism is a position sensor that is communicatively connected to the control circuit board, and the position sensor detects the specific location of the sound source 26.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
