The notch is matched with the corresponding receiving groove 31 under the drive of the rotating motor 34, so that the solid fragrance in the corresponding receiving groove 31 can pass through the notch for dissemination.

[0068] Preferably, in some embodiments, a cover 33 having a notch at one end is used so that when a rotating motor 34 rotates, the notch of the end cover 9 can be matched with the corresponding receiving slot 31, thereby exposing the corresponding receiving slot 31, and the solid fragrance in the receiving slot 31 is diffused and volatilized under the drive of the fan 32. The solid fragrance in multiple receiving slots 31 can be combined with the setting of corresponding emotional states to control the rotating motor 34 to drive the cover 33 to open the corresponding receiving slot 31 for odor diffusion.

[0069] In the monitoring control specifically implemented, as an example, the projection sound box is applied to the scene of soothing the emotions of infants and children. In this scene, for example, the target person can be an infant and child.

[0070] Step 110, collecting human body feature information.

[0071] In this embodiment, the steps of this embodiment can be performed when the projection sound box is powered on. In other examples, the projection sound box can also access the network to communicate with external devices, and the projection sound box can also communicate with external devices through Bluetooth or other methods.

[0072] Among them, the human body sensor 11 and the noise sensor 12 can accurately collect the human body feature information and noise information of the target person, and can accurately determine whether the human body is in the sensing area; optionally, a displacement sensor is set on the projection sound box to sense the displacement of the human body features, and the distance measuring sensor detects the relative distance between the human body features and the shell 2.

[0073] Through the recording and collection of the visual sensor 10, the visual sensor 10 can be a camera.

[0074] In sub-step 111, the human body sensor 11, the displacement sensor and the distance measuring sensor detect the relative position of the human body features with respect to the projection sound box, and the main control circuit board 3 drives the rotating motor 154, which in turn drives the housing 2 to rotate along the rotating table 24 of the rotating member 14 through the base member 13, and makes the visual sensor 10 face the target person, and further makes the directional speaker 8 face the target person, so as to facilitate the subsequent directional propagation of audio.

[0075] Optionally, a directional rotation switch is provided on the housing 2. After the escape alarm button is pressed, when the human body is displaced, the housing 2 can be controlled to follow the target person, and the rotation angle of the housing 2 is 0-200 degrees.

[0076] Optionally, a separation alarm button is provided on the housing 2. After the separation alarm button is pressed, the buzzer 23 is connected to the main control circuit board 3. When the displacement of the human body is out of the sensing area, the buzzer 23 sounds an alarm.

[0077] Optionally, through the communication connection of the pressing member 19, pressing the pressing member 19 can control the switch of the directional rotation and the switch of the escape alarm key, and corresponding pressing adjustment of the audio and / or projection can also be set to switch.

[0078] Step 120, identifying the collected human body features.

[0079] After collecting the human body feature information, the matching degree between the human body feature and the information recognition module on the main control circuit board 3 is further identified.

[0080] As an example, the collected emotional state is one of an angry howling state, a crying state, and a sleeping state. The feature unit in the information recognition module can be a default feature unit or a feature unit pre-entered by the user, and each feature unit corresponds to the corresponding emotional state. For example, multiple default feature units are pre-stored, such as a howling unit, a laughing unit, a crying unit, and a sleeping unit.

[0081] Step 130 , identifying that the human body features match the corresponding emotional state, and playing the audio data and / or projection image corresponding to the emotional state.

[0082] In this step, when the information recognition module identifies and matches the currently collected human characteristic emotional state as a specified emotional state, the playback control module receives the signal and plays the audio and / or projection image corresponding to the specified emotional state. For example, when the current emotional state is identified as crying, audio or video that soothes crying emotions is played to achieve the effect of soothing people's emotions, thereby improving the intelligence of the playback device and simplifying user operations. Under the directional propagation of the directional speaker 8, the sound pollution to the external environment can be reduced.

[0083] Optionally, a solid fragrance matching the corresponding emotional state is set in the receiving groove 31 of the fragrance diffuser 30, and the rotating motor 34 is controlled to open the corresponding receiving groove 31 through the cover 33, and the fragrance is diffused and volatilized under the drive of the fan 32, thereby having a soothing effect through the sense of smell.

[0084] In summary, through the continuous monitoring of the human body sensor 11 and the adjustment of the rotating component 15, the directional speaker 8 can perform directional propagation relative to the human body and be isolated from the external environment, thereby creating an immersive soothing environment for the target person. This immersive soothing experience can further improve the comfort and effectiveness of the service, allowing the target person to be more relaxed and happy when enjoying the service. It provides the target person with a more personalized, accurate and effective soothing service, improves the intelligence level of the service, and enhances the user's experience and satisfaction.
