[0023] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] In order to adjust the position of the microphone, there are mainly the following two forms. The first form is to set up structures such as a rotating shaft and a hinge to enable the microphone to rotate, and then manually rotate the microphone during use to achieve position adjustment. This method requires manual adjustment, is not intelligent enough and the effect is not good.

[0026] In order to better illustrate a microphone in the embodiments of the present invention, the following will be described in detail in conjunction with specific embodiments and the accompanying drawings. Specifically as follows:

[0027] Embodiment 1

[0028] As Figure 1 shown, a microphone provided by Embodiment 1 of the present invention is used to pick up an audio signal to convert the audio signal into a corresponding electrical signal. Specifically, the microphone includes a microphone main body 10, a microphone bracket 20, and a suspension assembly 30 disposed between the microphone main body 10 and the microphone bracket 20. The suspension assembly 30 can make the microphone main body 10 in a suspended state relative to the microphone bracket 20. The suspension assembly 30 includes a mutually adapted suspension magnet 31 and a suspension coil 32; wherein, one of the suspension magnet 31 and the suspension coil 32 is disposed on the microphone main body 10, and the other is disposed on the microphone bracket 20. According to the principle of magnetic suspension control, by inputting a current to the suspension magnet 31, a suspension magnetic field can be excited, and the coil generates a Lorentz force under the action of the suspension magnetic field, so that the microphone main body 10 is in a suspended state. In addition, a changing current generates a changing magnetic field, and the changing magnetic field can control the Lorentz force received by the suspension coil 32, thereby controlling the position and direction of the microphone main body 10, and thus adjusting the suspension pose, truly realizing the function of a contactless noise reduction microphone.

[0029] In specific implementation, as Figure 1As shown, a receiving cavity 21 is provided on the microphone holder 20, at least a part of the microphone body 10 is received in the receiving cavity 21, and the suspension assembly 30 is located in the receiving cavity 21. Specifically, in this embodiment, the suspension magnet 31 is specifically embedded in the inner wall of the receiving cavity 21. The suspension magnet 31 may specifically be an annular magnet. The suspension coil 32 is disposed around the outer wall of the microphone body 10, and the suspension coil 32 is located within the coverage magnetic field range formed by the suspension magnet 31. On the one hand, the suspension assembly 30 can suspend the microphone body 10 by the principle of magnetic levitation, playing a role in fixing the microphone body 10. On the other hand, it is also used to adjust the position and direction of the microphone body 10. Of course, due to the reciprocal nature of the suspension effect, in some alternative embodiments, the suspension magnet 31 and the suspension coil 32 may also be interchanged, that is, the suspension magnet 31 is disposed around the outer wall of the microphone body 10, and the suspension coil 32 is embedded in the inner wall of the receiving cavity 21.

[0030] Specifically, the microphone body 10 specifically includes a housing 11, a main microphone 12 provided at the front end of the housing 11, and a metal mesh head 13 provided at the front end of the housing 11 and covering the main microphone 12. The metal mesh head 13 can shield electromagnetic interference, and the main microphone 12 is used to collect sound signals. In order for magnetic levitation, wireless charging, and wireless audio to work properly, the housing 11 is made of a non-metallic housing. The suspension coil 32 is disposed around the housing 11. In some alternative embodiments, a display device may also be embedded in the housing 11 to display the battery level, switch status, and speech position identifier of the microphone, etc. For example, as Figure 1 shown, by embedding a display lamp 14 in the housing 11, a red dot mark can be displayed to mark the correct speech position of the microphone.

[0031] In addition, the microphone further includes a sensing and control component 40 electrically connected to the suspension assembly 30. When the sensing and control component 40 receives an induction signal, it adjusts the suspension pose of the microphone body 10 relative to the microphone holder 20 by controlling the suspension assembly 30. In specific implementation, the induction signal is any one or more of a sound signal, a gesture signal, and a switch electrical signal, that is, in specific implementation, the suspension pose of the microphone body 10 can be adjusted by gestures, voice control, sound source localization, or an electric switch, etc.

[0032] As a preferred implementation manner, as Figure 1As shown in the figure, the sensing and control component 40 includes a secondary microphone 41 and a controller 42 electrically connected to the secondary microphone 41; the main microphone 12 is electrically connected to the controller 42; wherein, the controller 42 is electrically connected to the suspension component 30, and is used to locate the sound source according to the sound signals collected by the main microphone 12 and the secondary microphone 41, and adjust the suspension pose of the microphone body 10 relative to the sound source by controlling the suspension component 30. Specifically, according to the sound localization principle, through the cooperation of the main microphone 12 and the secondary microphone 41, the position of the sound source can be located, the current speaking position can be found, and then the position and direction of the microphone body 10 can be adjusted by controlling the current signal of the suspension magnet 31, so that it can better align with the sound source position and improve the sound pickup effect. Specifically, the secondary microphone 41 is arranged on the microphone body 10, specifically on the outer shell 11 or inside the outer shell 11, and the controller 42 is arranged on the microphone bracket 20. At this time, in order to realize the electrical connection between the microphone body 10 and the controller 42, an electrical connection device for transmitting signals and / or charging is also provided between the microphone bracket 20 and the microphone body 10. Since in the embodiment of the present invention, the microphone body 10 is in a suspended state relative to the microphone bracket 20, therefore, in specific implementation, the electrical connection device is preferably a radio connection device 24 capable of realizing wireless charging and / or wireless signal transmission, such as a wireless charging module, a wireless audio transmission module or a combination of the two. Specifically, as Figure 1 shown, the radio connection device 24 is specifically arranged between the bottom of the microphone body 10 and the bottom of the accommodation cavity 21.

[0033] In specific implementation, the microphone bracket 20 is provided with a charging cable 22 and a data interface 23. The sound signal collected by the main microphone 12 is transmitted to the controller 42 through the radio connection device, and then can be output outward through the data interface 23. At the same time, the sound signal collected by the secondary microphone 41 is also transmitted to the controller 42 through the radio connection device. The controller 42 locates the sound source according to the sound signals collected by the main microphone 12 and the secondary microphone 41, and then controls the suspension component 30. The charging cable 22 is mainly used to supply power to the suspension magnet 31, and is also used to charge the microphone through the radio connection device.

[0034] In summary, in the microphone of the embodiment of the present invention, by setting the suspension component 30, the microphone body 10 is in a suspended state relative to the microphone bracket 20. In addition, by setting the sensing and control component 40 to control the suspension component 30, and automatically controlling the suspension component 30 according to the induction signal sensed by the sensing and control component 40, so as to automatically adjust the suspension pose of the microphone body 10 relative to the microphone bracket 20. It not only realizes the automatic adjustment of the pose of the microphone position, but also does not involve complex mechanical structures, has low cost and is beneficial to the miniaturization of the product.

[0035] Embodiment 2

[0036] Please refer to Figure 2, shown is the microphone in the second embodiment of the present invention. The difference between the microphone in this embodiment and the microphone in the first embodiment is as follows:

[0037] The sensing and control component 40 further includes a gesture sensing module 43, and the gesture sensing module 43 is electrically connected to the controller 42. At this time, the controller 42 is further configured to adjust the suspension pose of the microphone body 10 by controlling the suspension component 30 according to the gesture signal sensed by the gesture sensing module 43. Specifically, the gesture sensing module 43 is disposed on the outer shell 11 of the microphone body 10. That is, based on the solution of automatically adjusting the microphone position according to sound source localization in the first embodiment, this embodiment further adds gesture sensing and control, that is, the microphone position is adjusted correspondingly by sensing the user's gesture, so as to have more adjustment methods and can be adapted to more application scenarios.

[0038] Of course, it should be noted that in other alternative embodiments, the sensing and control component 40 may also be composed only of the gesture sensing module 43 and the controller 42. In this case, the microphone position is mainly adjusted correspondingly by sensing the user's gesture.
