At present, the mature directional horn technology exists, sound only spreads to the designated direction, the emitted sound wave energy is concentrated, and the sound intensity is not obviously attenuated along with the distance. By this technique, fixed-direction sound transmission can be realized on a mobile communication device.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide an intelligent desk lamp capable of preventing others from being disturbed and a method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme:
an intelligent desk lamp capable of preventing people from being disturbed comprises a desk lamp body, a camera arranged on the desk lamp body, a distance measuring module, a control module and an active directional loudspeaker, wherein the control module and the active directional loudspeaker are arranged in the desk lamp body; the camera, the distance measuring module and the active directional loudspeaker are all in communication connection with the control module;
the control module is used for acquiring an image in the current shooting direction through the camera before controlling the active directional loudspeaker to play sound, identifying face information of a user in the image and accordingly identifying the direction of the user relative to the intelligent desk lamp, measuring the distance between the user and the intelligent desk lamp through the distance measuring module, then obtaining corresponding volume according to the distance of the user and a preset mathematical relation between the volume and the distance, and finally controlling the active directional loudspeaker to play sound directionally to the direction of the user by using the volume.
Furthermore, the user inputs face information in advance through the camera and stores the face information in the control module, and the control module identifies the face information in the image and then compares the face information with the stored face information to determine the face information of the user.
Furthermore, the distance measuring module adopts an infrared distance measuring module or an ultrasonic distance measuring module.
The invention provides a method for utilizing the intelligent desk lamp, which comprises the following specific processes:
when a user needs to play sound in the process of using the intelligent desk lamp, the control module acquires an image in the current shooting direction through the camera before controlling the active directional loudspeaker to play the sound, identifies the face information of the user in the image and identifies the position of the user relative to the intelligent desk lamp according to the face information, measures the distance between the user and the intelligent desk lamp through the distance measuring module, obtains corresponding volume according to the distance between the user and the preset volume and the mathematical relation of the distance, and finally controls the active directional loudspeaker to play the sound to the position of the user with the volume.
The invention has the beneficial effects that: the intelligent desk lamp can effectively prevent students from influencing other people when using the intelligent desk lamp, so that the intelligent desk lamp is more practical and humanized.
Drawings
Fig. 1 is a schematic block diagram of an intelligent desk lamp in embodiment 1 of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
Example 1
The embodiment provides an intelligent desk lamp capable of preventing disturbance to others, which comprises a desk lamp body, a camera arranged on the desk lamp body, a distance measuring module, a control module and an active directional loudspeaker, wherein the control module and the active directional loudspeaker are arranged in the desk lamp body; the camera, the distance measuring module and the active directional loudspeaker are all in communication connection with the control module;
the control module is used for acquiring images in the current shooting direction through the camera before controlling the active directional loudspeaker to play sound (when a user uses the intelligent desk lamp to listen to stories, watch video animation, learn communication and the like and needs to play sound), identifying face information of the user in the images and accordingly identifying the direction of the user relative to the intelligent desk lamp, measuring the distance between the user and the intelligent desk lamp through the distance measuring module, then obtaining corresponding volume according to the distance between the user and a preset mathematical relationship between the volume and the distance, and finally controlling the active directional loudspeaker to play sound directionally to the direction of the user by using the volume.
Furthermore, the user inputs face information in advance through the camera and stores the face information in the control module, and the control module identifies the face information in the image and then compares the face information with the stored face information to determine the face information of the user. Therefore, the interference of other face information in the image can be avoided.
Furthermore, the distance measuring module adopts an infrared distance measuring module or an ultrasonic distance measuring module.
Specifically, in order to ensure that the distance between the user and the intelligent desk lamp can be smoothly measured by the distance measuring modules in different directions, a plurality of distance measuring modules with proper quantity can be arranged on the intelligent desk lamp, and the distance measuring range is expanded.
It should be noted that the mathematical relationship between the volume and the distance can be obtained through experiments in advance, and the sound played at the volume obtained according to the mathematical relationship should be attenuated to disappear basically after reaching the user.
Example 2
The embodiment provides a method for utilizing the intelligent desk lamp in the embodiment 1, which comprises the following specific processes:
when a user needs to play sound (listen to stories, watch video animation, learn communication and the like) in the process of using the intelligent desk lamp, the control module acquires an image in the current shooting direction through the camera before controlling the active directional loudspeaker to play the sound, identifies face information of the user in the image and accordingly identifies the direction of the user relative to the intelligent desk lamp, measures the distance between the user and the intelligent desk lamp through the distance measuring module, then obtains corresponding volume according to the distance of the user and a preset mathematical relationship between the volume and the distance, and finally controls the active directional loudspeaker to play the sound directionally to the direction of the user by using the volume.
By the method, the active directional loudspeaker directionally plays sound to the user, the sound volume is obtained according to the distance, and the sound basically cannot reach other people at other distances and in other directions, so that the influence on the other people is reduced when the intelligent desk lamp plays the sound.
Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
