[0042] like Figure 1As shown, in an embodiment of the sound pickup system proposed by the present invention, the sound pickup system includes:

[0043] A live broadcast device 10, comprising a device microphone 13, a Bluetooth module, a processor, and a controller, wherein the device microphone 13 is connected to the processor, and the processor and the Bluetooth module are respectively connected to the controller;

[0044] A Bluetooth microphone 30, wherein the Bluetooth microphone 30 has a first state of establishing a Bluetooth connection with the Bluetooth module and a second state of disconnecting from the Bluetooth module;

[0045] The processor is used to determine whether the Bluetooth microphone 30 is in the first state, and send a control instruction to the controller according to the determination result. The controller is used to control the Bluetooth microphone 30 or the device microphone 13 to pick up sound according to the control instruction.

[0046] Specifically, in one embodiment, when the processor determines that the Bluetooth microphone 30 is in the first state, it sends a control instruction to the controller, and the controller is used to control the Bluetooth microphone 30 to pick up sound according to the control instruction. When the processor determines that the Bluetooth microphone 30 is not in the first state, it sends a control instruction to the controller, and the controller is used to control the device microphone 13 to pick up sound according to the control instruction.

[0047] In the technical solution of the present invention, the sound pickup system 100 includes a device microphone 13 and a Bluetooth microphone 30. After the Bluetooth microphone 30 establishes a Bluetooth connection with the live broadcast device 10, the controller can control the device microphone 13 or the Bluetooth microphone 30 to pick up sound. The user can carry the Bluetooth microphone 30 with him. Even if the user's position and angle relative to the live broadcast device 10 change, it will not affect the sound pickup effect, providing the user with a consistent sound pickup or recording experience.

[0048] like Figure 3 、 4 As shown, in one embodiment, when the Bluetooth microphone 30 is in the first state, the Bluetooth microphone 30 includes a first installation state installed on the live broadcast device 10 and a second installation state separated from the live broadcast device 10, the Bluetooth microphone 30 includes a wireless mic PIN pin 31, and the live broadcast device 10 includes a spring pin 15 that cooperates with the wireless mic PIN pin. In the first installation state, the wireless mic PIN pin 31 is connected to the spring pin 15.

[0049] In this embodiment, when the Bluetooth microphone 30 is in the first state, that is, when the Bluetooth microphone 30 establishes a Bluetooth connection with the Bluetooth module, the Bluetooth microphone 30 can be installed on the live broadcast device 10. At this time, the wireless mic PIN pin 31 of the Bluetooth microphone 30 is connected with the spring pin 15 of the live broadcast device 10, so that the Bluetooth microphone 30 can communicate with the live broadcast device 10 through the wireless mic PIN pin 31 and the spring pin 15. At this time, the Bluetooth microphone 30 can be charged, turned on and off, automatically paired, and connected. Furthermore, in one embodiment, the Bluetooth microphone 30 and the live broadcast device 10 can be connected by magnetic attraction to connect the wireless mic PIN pin 31 of the Bluetooth microphone 30 with the spring pin 15 of the live broadcast device 10, so as to communicate. Specifically, magnets can be installed at the relative positions of the Bluetooth microphone 30 and the live broadcast device 10.

[0050] like Figure 2 As shown, in one embodiment, the live broadcast device 10 is further provided with an audio input port 50, and the audio input port 50 is respectively connected to the processor and the controller for connecting to an external microphone.

[0051] In this embodiment, the audio input port 50 is generally a 4.5mm interface, and the external microphone is connected to the live broadcast device 10 through the audio input port 50. When the Bluetooth microphone 30 cannot be used normally, for example, when there is no power, the external microphone can be connected through the audio input port 50, so that the external microphone can also be used to pick up sound during the live broadcast or meeting. Furthermore, in one embodiment, when the processor determines that the external microphone is connected to the live broadcast device 10, it will send a control instruction to the controller, and the controller is used to control the external microphone to pick up sound according to the control instruction.

[0052] like Figure 3 As shown, in one embodiment, a clip 20 is further included, and the clip 20 includes a clamping portion 21 and a mounting portion 23 that are interconnected. The mounting portion 23 is installed on the housing of the Bluetooth microphone 30, and the clamping portion 21 is located on the outside of the wireless mic PIN needle 31, and the clamping portion 21 is provided with a through hole opposite to the wireless mic PIN needle 31.

[0053] In this embodiment, a clip 20 is mounted on the Bluetooth microphone 30, allowing it to be secured to a suitable sound pickup location, such as a user's clothing or a seat. A clamping portion 21 is located outside the wireless mic PIN 31 and defines a through-hole opposite the wireless mic PIN 31. This protects the wireless mic PIN 31 from bumps and damage.

[0054] like Figure 1 、 2 As shown, in one embodiment, the live broadcast device 10 also includes a shell 14, a camera 16 and a support part 17, the spring pin 15 is arranged above the shell 14, an installation cavity is formed inside the shell 14, the camera 16 is installed in the installation cavity, the device microphone 13 is installed in the installation cavity and is located below the camera 16, and the support part 17 is installed below the shell 14.

[0055] In this embodiment, the live broadcast device 10 also includes a housing 14, a camera 16, and a support 17. The housing 14 is used to mount the camera 16 and the device microphone 13. The camera 16 is used to film the live broadcast device. Compared to electronic devices such as mobile phones, the camera 16 has a larger lens. During live broadcasts, the live broadcast device 10 is placed directly in one place, which prevents the camera 16 lens from shaking, allowing for a better live broadcast image. The device microphone 13 is located below the camera 15 and is used to pick up sound. The support 16 is used for support and allows the live broadcast device 10 to be stably placed on a supporting surface, such as the ground or a table, to obtain a better live broadcast image. Specifically, the housing 14 of the live broadcast device 10 has a generally cylindrical structure. The camera 16 lens is mounted on one side of the housing 14 and is located in the center of the mounting cavity. An audio input port 50 is provided on the opposite side of the housing. A power switch is also provided on the opposite side of the housing to turn the live broadcast device 10 on and off.

[0056] The present invention also provides a multimedia device, which includes the sound pickup system 100. The specific structure of the sound pickup system 100 is similar to the above-mentioned embodiments. Since the multimedia device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here. The multimedia device may also include a display screen and an audio player. The display screen and audio player are used to display the live broadcast images and sound pickup effects collected by the sound pickup system 100 to the host, allowing the user to adjust the live broadcast status in a timely manner and obtain a good live broadcast experience.

[0057] like Figure 5 As shown, the present invention also proposes a sound pickup method, comprising the following steps:

[0058] Determine whether the Bluetooth microphone 30 has established a Bluetooth connection with the Bluetooth module, and obtain a first determination result;

[0059] A comprehensive judgment result is obtained according to the first judgment result and the preset priority information, wherein the preset priority information is that the priority of the Bluetooth microphone 30 is greater than the priority of the device microphone 13;

[0060] The sound pickup system 100 is controlled to pick up sound according to the comprehensive judgment result.

[0061] In this embodiment, after presetting the priority of the microphone according to actual needs, a comprehensive judgment result is obtained based on the preset priority and the first judgment result. The preset priority information can be that the priority of the Bluetooth microphone 30 is greater than that of the device microphone 13. In this way, when the processor determines that the live broadcast device 10 is connected to the Bluetooth microphone 30, it will send a control instruction to the controller according to the judgment result, and the controller controls the Bluetooth microphone 30 to pick up sound according to the control instruction. It should be noted that in this embodiment, the preset priority information is that the priority of the Bluetooth microphone 30 is greater than the priority of the device microphone 13. However, in other embodiments, the user can set different preset priority information according to actual needs. This disclosure does not limit the preset priority information. For example, the user can set the preset priority information so that the priority of the Bluetooth microphone 30 is less than the priority of the device microphone 13. In this way, when the processor determines that the live broadcast device 10 is connected to the Bluetooth microphone 30, it will send a control instruction to the controller according to the judgment result, and the controller controls the device microphone to pick up sound according to the control instruction.

[0062] Furthermore, the specific steps of controlling the sound pickup system 100 to pick up sound according to the comprehensive judgment result include:

[0063] If the first judgment result is yes;

[0064] The comprehensive judgment result is to control the Bluetooth microphone to pick up sound.

[0065] In this embodiment, the first judgment result is obtained by judging whether the Bluetooth microphone 30 establishes a Bluetooth connection with the Bluetooth module. Since the preset priority information is that the priority of the Bluetooth microphone 30 is greater than that of the device microphone 13, it is judged that after the Bluetooth microphone 30 establishes a Bluetooth connection with the live broadcast device 10, the Bluetooth microphone 30 will be controlled to pick up sound, while the device microphone 13 of the live broadcast device 10 will not be able to pick up sound.

[0066] Furthermore, the sound pickup system further includes an audio input port 50, and before the step of obtaining a comprehensive judgment result based on the first judgment result and the preset priority information, further includes:

[0067] Determine whether the audio input port 50 is connected to an external microphone, and obtain a second determination result;

[0068] The steps of obtaining a comprehensive judgment result based on the first judgment result and the preset priority information, wherein the preset priority information indicates that the priority of the Bluetooth microphone 30 is greater than the priority of the device microphone 13, include:

[0069] A comprehensive judgment result is obtained based on the first judgment result, the second judgment result and the preset priority information, wherein the preset priority information is: the priority of the external microphone is greater than the priority of the Bluetooth microphone 30, and the priority of the Bluetooth microphone 30 is greater than the priority of the device microphone 13.

[0070] In this embodiment, after the processor determines that the external microphone is connected to the live broadcast device 10, it will send a control instruction to the controller based on the judgment result. The controller controls the external microphone with the highest priority to pick up sound according to the control instruction, and controls the device microphone 13 and the Bluetooth microphone 30 of the live broadcast device 10 to be unable to pick up sound.

[0071] It should be noted that in this embodiment, the preset priority information may be: the priority of the external microphone is greater than the priority of the Bluetooth microphone 30, and the priority of the Bluetooth microphone 30 is greater than the priority of the device microphone 13. In other embodiments, the preset priority information can be set according to user needs, and this disclosure does not limit this preset priority information. For example, the priority of the external microphone is less than the priority of the Bluetooth microphone 30, and the priority of the Bluetooth microphone 30 is less than the priority of the device microphone 13. In this case, since the device microphone 13 has the highest priority, the controller controls the device microphone with the highest priority to pick up sound according to the control instruction. Alternatively, the priority of the Bluetooth microphone is greater than the priority of the external microphone, and the priority of the external microphone is greater than the priority of the device microphone. In this case, after the processor determines that the Bluetooth microphone is connected to the live broadcast device 10, it will issue a control instruction to the controller based on the determination result. According to the control instruction, the controller controls the Bluetooth microphone with the highest priority to pick up sound, while controlling the device microphone 13 of the live broadcast device 10 and the external microphone to not pick up sound.

[0072] Furthermore, in one embodiment, the step of controlling the sound pickup system 100 to pick up sound according to the comprehensive judgment result specifically includes:

[0073] If the comprehensive judgment result is to control the Bluetooth microphone 13 to pick up sound, then determine whether the Bluetooth microphone 13 is installed in the live broadcast device 10;

[0074] If yes, controlling the Bluetooth microphone 30 of the sound pickup system 100 to pick up sound within the first sound pickup range;

[0075] If not, the Bluetooth microphone 30 of the sound pickup system 100 is controlled to pick up sound within a second sound pickup range, wherein the second sound pickup range is smaller than the first sound pickup range.

[0076] In this embodiment, if the comprehensive judgment result indicates that the Bluetooth microphone 13 is controlled to pick up sound, it is determined whether the Bluetooth microphone 13 is installed on the live broadcast device 10. If the Bluetooth microphone 13 is installed on the live broadcast device 10, the Bluetooth microphone 30 of the sound pickup system 100 is controlled to pick up sound within a first sound pickup range. If the Bluetooth microphone 13 is not installed on the live broadcast device 10, the Bluetooth microphone 30 of the sound pickup system 100 is controlled to pick up sound within a second sound pickup range, which is smaller than the first sound pickup range. If the Bluetooth microphone 13 is installed on the live broadcast device 10, it is fixed to the live broadcast device 10 and needs to pick up sound within a larger sound pickup range to achieve a better live broadcast effect and not miss the user's voice. If the Bluetooth microphone 13 is not connected to the live broadcast device 10, it will generally move with the user, for example, the user may clip it to their clothing. In this case, the Bluetooth microphone 30 can pick up sound within a smaller sound pickup range, thereby reducing interference from external noise and achieving a better live broadcast effect.

[0077] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
