DETAILED DESCRIPTION

[0027] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] like Figure 1-Figure 3 As shown, the utility model discloses an angle-adjustable microphone device, which includes a base 1, a rotating base 2, a microphone 4 and a control component, wherein the rotating base 2 is rotatably mounted on the base 1 through a second rotating shaft 521, and the microphone 4 is rotatably mounted on the rotating base 2 through a first rotating shaft 511, and the rotating axis of the first rotating shaft 511 is arranged at an angle to the rotating axis of the second rotating shaft 521. The control component is used to control the rotation of the first rotating shaft 511 and / or the second rotating shaft 521, so that the rotating base 2 and / or the microphone 4 rotate.

[0031] Specifically, this embodiment is described by taking the example that the rotation axis of the first rotating shaft 511 is perpendicular to the rotation axis of the second rotating shaft 521, that is, the first rotating shaft 511 is set to be parallel to the vertical plane, and the second rotating shaft 521 is set to be parallel to the horizontal plane. Rotating the first rotating shaft 511 can adjust the height position of the sound receiving inlet of the microphone 4 relative to the user, and rotating the second rotating shaft 521 can change the direction in which the microphone 4 is aligned.

[0032] On the basis of the above structure, when using the microphone device of the present application, the user can hold the base 1 or install and fix the base 1 in a specific position. When it is necessary to adjust the height position of the sound receiving inlet of the microphone 4, such as when the height of the users is different or the users raise or lower their heads, the elevation direction of the sound receiving inlet of the microphone 4 can be adjusted by rotating the first rotating shaft 511 until the sound receiving inlet of the microphone 4 is aligned with the user's mouth. When it is necessary to adjust the alignment direction of the microphone 4, such as when the user's facial orientation changes or it is another user's turn to speak, the second rotating shaft 521 can be rotated to adjust the rotation angle of the rotating base 2, and the microphone 4 rotates with the rotating base 2 until the sound receiving inlet of the microphone 4 faces the direction of the user.

[0033] The microphone 4 of this embodiment can realize automatic adjustment of the angle in two directions through the first rotating shaft 511 and the second rotating shaft 521, so as to ensure that the microphone 4 can receive and process the sound within a suitable range to obtain a good sound receiving effect. In addition, when adjusting the angle in two directions of the microphone 4 of this embodiment, it is realized by controlling the rotation of the first rotating shaft 511 and / or the second rotating shaft 521 by the control component, without manual adjustment, and the operation is convenient, which can well meet the use requirements.

[0034] It should be noted that, in other embodiments, the first rotating shaft 511 and the second rotating shaft 521 may also be arranged to be tilted respectively, and the tilting directions of the first rotating shaft 511 and the second rotating shaft 521 are different, so that when the first rotating shaft 511 and the second rotating shaft 521 rotate respectively, the microphone 4 can also be driven to rotate in two different directions. In short, the microphone 4 can be adjusted in two directions when the first rotating shaft 511 and the second rotating shaft 521 rotate.

[0035] It should also be noted that the rotation of the first rotating shaft 511 and / or the second rotating shaft 521 of this embodiment can be achieved by remote control of the control component or by the control component itself driving the first rotating shaft 511 and / or the second rotating shaft 521 to rotate, without limitation.

[0036] Specifically, this embodiment is described in detail by driving the first rotating shaft 511 and / or the second rotating shaft 521 to rotate by the control component itself. In this embodiment, the control component includes a detector 6, a first motor 51 and a second motor 52, the output shaft of the first motor 51 is formed as the first rotating shaft 511, and the output shaft of the second motor 52 is formed as the second rotating shaft 521. The detector 6 is electrically connected to the first motor 51 and the second motor 52, and the detector 6 is arranged on the rotating seat 2. The detector 6 can detect the position information of a person and transmit the position information to the first motor 51 and the second motor 52, and the first motor 51 and the second motor 52 then drive the rotating seat 2 and / or the microphone 4 to rotate to the corresponding position.

[0037] Based on the above structure, when the microphone device of this embodiment is used, the detector 6 detects the position information of the user's voice or mouth and transmits the position information to the first motor 51 and the second motor 52. Since the detector 6 is arranged on the rotating seat 2, when the detector 6 detects the position information of the user's voice or mouth and transmits it to the first motor 51 and the second motor 52, the second motor 52 first drives the second rotating shaft 521 to rotate according to the position information transmitted by the detector 6, and then the rotating seat 2 adjusts the microphone 4 arranged thereon to the position direction facing the user as the second rotating shaft 521 rotates. Thereafter, the detector 6 keeps the position direction facing the user as the rotating seat 2 rotates, that is, the detector 6 always points to the position direction of the user. At the same time, when the first motor 52 receives the position information transmitted by the detector 6, it drives the first rotating shaft 511 to rotate, and the microphone 4 adjusts the elevation angle of the sound receiving entrance of the microphone 4 thereon as the first rotating shaft 511 rotates until it is facing the position of the user's voice or mouth. Thereafter, the sound receiving entrance of the microphone 4 always points to the user's voice or mouth.

[0038] In this embodiment, the detector 6 detects the user's position information and transmits the position information to the first motor 51 and the second motor 52, so as to realize the coordinated rotation of the first rotating shaft 511 and the second rotating shaft 521, thereby realizing the coordinated adjustment of the alignment direction of the microphone 4 and the directional angle of the sound receiving entrance of the microphone 4, so that the microphone 4 can receive and process sound within a certain range to ensure a good sound receiving effect, and when in use, the microphone 4 can adjust its directionality as the user's mouth or the sound source moves, replacing manual operation and better meeting the use requirements.

[0039] More specifically, the detector 6 of this embodiment can be a sensor or camera in the prior art. When the detector 6 is a sound sensor, the above position information is formed by the position of the sound emitted by the user. When the detector 6 is a camera, the camera can capture and shoot the face to generate image information. At this time, the position information is formed by the sound emitted by the user. Of course, in other embodiments, the detector 6 can also be an infrared sensor in the prior art, as long as it can detect the user's voice or mouth position information, without limitation.

[0040] Furthermore, if Figure 1 , Figure 2 and Figure 3 As shown, a mounting seat 3 is provided at the top of the swivel seat 2, the base 1 is provided with an opening and a first mounting cavity 10, the mounting seat 3 is provided with a second mounting cavity 30, a first motor 51 is installed in the first mounting cavity 10, a first rotating shaft 511 on the first motor 51 passes through the side wall of the first mounting cavity 10 and is fixedly connected to the side wall of the microphone 4, a second motor 52 is installed in the second mounting cavity 30 through the opening, and the swivel seat 2 cover is provided at the top of the base 1 and is fixedly connected to the second rotating shaft 521.

[0041] In this embodiment, the two motors are installed in corresponding installation cavities respectively, which not only protects the motors from contamination but also ensures the safety during use.

[0042] Furthermore, if Figure 3 As shown, since the connection between the second rotating shaft 521 on the second motor 52 and the rotating seat 2 is subjected to the pulling force of the gravity of the second motor 52, the connection strength between the second rotating shaft 521 and the rotating seat 2 is affected. Therefore, a support plate 12 can be set in the second installation cavity 30. The support plate 12 can be formed by extending the side wall of the second installation cavity 30 toward the inside, or by extending the bottom wall of the second installation cavity 30 toward the opening direction. As long as it can provide support for the second motor 52 to prevent the second motor 52 from falling under the action of gravity, it will be sufficient.

[0043] Furthermore, a first connecting portion 41 is provided on the side wall of the microphone 4, and the first rotating shaft 511 is rotatably provided on the side wall thereof after the first motor 51 is installed in the first installation cavity 10, and is fixedly connected to the first connecting portion 41. A second connecting portion 21 is provided at the bottom end of the rotating seat 2 toward the second installation cavity 30, and the second rotating shaft 521 is fixedly connected to the second connecting portion 21.

[0044] In this embodiment, the first connection part 41 and the second connection part 21 can be mounting hole seats, and the mounting hole seats are provided with protrusions, and the first rotating shaft 511 and the second rotating shaft 521 have notches, and the protrusions and the notches are engaged to prevent the rotating shaft and the corresponding connection parts from rotating relative to each other. Of course, in other embodiments, the first connection part 41 and the second connection part 21 can also be mounting hole seats with notches, and the first rotating shaft 511 and the second rotating shaft 521 are provided with protrusions that can be engaged with the notches, or the first connection part 41 and the second connection part 21 are threaded holes, and threads are correspondingly provided on the first rotating shaft 511 and the second rotating shaft 521, and the threads are fixedly connected with the threaded holes, etc. In order to further improve the connection strength, fixing glue, etc. can also be filled, or the rotating shaft and the connection part can be fixedly connected by screws, etc.

[0045] Furthermore, in order to locate the position of the second rotating shaft 521, a cover plate 11 can be used to seal the opening, and a positioning hole corresponding to the second connecting portion 21 can be provided on the cover plate 11. On the one hand, after the second motor 52 is installed in the second installation cavity 30, if the rotating seat 2 is directly placed on the top of the base 1, the position of the second rotating shaft 521 may not be able to be smoothly aligned with the second connecting portion 21. However, after the positioning hole is provided, the second rotating shaft 521 can be smoothly fixedly connected to the second connecting portion 21 by passing through the positioning hole. On the other hand, the shaking of the second motor 52 during operation may affect the fixed connection between the second rotating shaft 521 and the second connecting portion 21. The second rotating shaft 521 passing through the positioning hole can limit the large shaking of the second motor 52.

[0046] Furthermore, in order to reasonably allocate the space of the microphone device, the mounting base 3 can be arranged on the circumferential side wall of the rotating base 2, so that the microphone 4 can be rotated directly above the rotating base 2 and the base 1 after being fixedly connected to the first rotating shaft 511. This embodiment reduces the occupied space by stacking the occupied space of the microphone 4, the rotating base 2 and the base 1 in the height space, making the microphone device more convenient to use.

[0047] Furthermore, the microphone device of this embodiment also includes a limiting structure, which includes a first limiting portion and a second limiting portion. The first limiting portion is arranged on the swivel seat 2, and the second limiting portion is arranged on the base 1. The first limiting portion and the second limiting portion are slidably matched and can prevent the swivel seat 2 from separating from the base 1 when rotating.

[0048] Specifically, Figure 4As shown, the first limiting portion of the present embodiment is a latching protrusion 22, and the second limiting portion is an annular groove 14. The annular groove 14 is arranged in a circumferential direction of the base 1. When the swivel seat 2 rotates, the latching protrusion 22 slides in cooperation with the annular groove 14. When the swivel seat 2 has a tendency to axially separate from the base 1, the latching protrusion 22 abuts against the inner wall of the annular groove 14. The inner wall of the annular groove 14 limits the displacement of the latching protrusion 22 along the axial direction of the base 1, thereby preventing the swivel seat 2 from separating from the base 1, further ensuring the connection strength between the second rotating shaft 521 and the swivel seat 2, and ensuring the stable rotation of the swivel seat 2.

[0049] It should be noted that, in other embodiments, the first limiting portion may be an annular groove 14, and the second limiting portion may be a latching protrusion 22. The number and shape of the latching protrusions 22 are not limited and may be continuous or discontinuous, and may be reasonably selected according to actual conditions.

[0050] Furthermore, considering that there are many usage scenarios, such as singing or giving a speech, a fixing portion 13 can be provided at the bottom of the base 1, and the fixing portion 13 can fix the base 1 at a specific position.

[0051] The fixing portion 13 of this embodiment is a fixing hole, which can be plugged into a specific position such as a positioning column on a podium to prevent the microphone device from moving on the podium and affecting the control component's adjustment of the microphone angle and direction. Of course, in other embodiments, the fixing portion 13 can also be a positioning column, etc., which can be reasonably designed according to specific circumstances.

[0052] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features.

[0053] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also considered to be within the protection scope of the utility model.
