Description

Technical Field

[0001] The invention relates to a broadcast loudspeaker, in particular to a broadcast loudspeaker used for campus monitoring. Background Art

[0002] The broadcast speaker is an important sound transmission device that can convert signals into sound and play music, conversations and other sound energy through air waves generated by vibration. The broadcast speakers will also be installed on the school campus to play relevant information, so that students can obtain information, complete certain instructions and tasks, and facilitate school management and information transmission.

[0003] With the development of the times, more and more schools will install cameras, microphones and other equipment, and connect them to their speakers. Through the combination of the three, they can complete the information entry, learning supervision and safety inspection of their students. However, the three are currently independent devices, which not only increases their cost, but also increases the space required for installation. During installation, certain installation technical requirements are also required for their installers, increasing the workload of their staff. Summary of the invention

[0007] Furthermore, the processing steps of the built-in sound source module 5 are specifically as follows: obtaining an external sound source through the microphone 2; determining whether the sound source is a trigger word; if the sound source is not a trigger word, returning to obtaining an external sound source through the microphone 2; if the sound source is a trigger word, further obtaining relevant sound source information for a period of time and proceeding to the next step; processing noise and extracting human voice; and outputting to the main processing mechanism 4.

[0008] Furthermore, the trigger phrases may be customized by the user according to the current usage scenario.

[0009] Furthermore, the stop condition for the sound source acquisition is that the sound source is continuously interrupted for 3s-5s, and the interruption duration can also be customized by the user.

[0010] Furthermore, the processing steps of the built-in image module 6 are specifically as follows: obtaining external image information through the camera 3; analyzing and determining whether the main body of the image information is a "portrait" image and the proportion of the "portrait"; if the proportion of the "portrait" in the image is too small, returning to obtaining external image information through the camera 3; if the image is a "portrait" and the proportion is normal, obtaining the current image information and proceeding to the next step; analyzing the image and transmitting it to the main processing mechanism 4.

[0011] Furthermore, the processing steps of the sound source terminal processing module 4-1 are specifically as follows: obtain the information processed by the built-in sound source module 5; extract and analyze its voice instructions; determine whether the instruction is a built-in voice instruction; if the instruction is a built-in voice instruction, perform the corresponding operation steps; if the instruction is not a built-in voice instruction, upload it to the host computer and obtain the instruction of the host computer; complete.

[0012] Furthermore, when the operation is performed without networking and network connection cannot be performed, the message "command error, please describe again" is output through the speaker body 1.

[0013] Furthermore, the processing steps of the image terminal processing module 4-2 are specifically as follows: obtaining image information processed by the built-in image module 6 through the built-in image module 6; adjusting the image so that the "portrait" is located in the middle of the image; comparing the "portrait" with the built-in preset frame; judging and analyzing the compared information; outputting corresponding instructions through the speaker body 1 based on the judged information; if the comparison difference exceeds a threshold, returning to obtain the image information processed by the built-in image module 6 through the built-in image module 6 until the "portrait" matches the preset frame.

[0014] Furthermore, the built-in preset picture frames in the comparison of the "portrait" with the built-in preset picture frames include facial expressions, body postures and clothing colors of the person.

[0015] After adopting the above technical scheme, the beneficial effect of the present invention is as follows: the broadcast speaker combines and installs its microphone, camera, etc. to make it an integrated structure, which can not only independently complete its tasks such as student information entry and student learning supervision, but also complete student control instructions and student shooting operations. During installation, its integrated structure is convenient for its staff to install, and its installation space requirements are also lower, which is more practical and convenient.
