Referring to fig. 5, a flowchart of a terminal control method according to an embodiment of the present application is shown. The method may be applied to the terminals shown in fig. 2 to 4, and may include the following steps.
In a possible implementation, the positioning component transmits the first millimeter wave signal through the array antenna. Illustratively, the positioning component transmits the first millimeter wave signal in various directions.
In a possible implementation manner, the first millimeter Wave signal is an FMCW (Frequency Modulated Continuous Wave) signal, and the FMCW signal is a high-Frequency Continuous Wave, and the Frequency of the FMCW signal changes according to a triangular Wave rule with time.
The first millimeter wave signal is reflected on the surface of an obstacle (for example, the surface of a target object), and then received, amplified and demodulated by a receiving antenna, so that a second millimeter wave signal is obtained. When the first millimeter wave is an FMCW signal, the second millimeter wave signal is also an FMCW signal.

And step 504, controlling the audio processing assembly to rotate through the motor control assembly based on the related information, wherein the rotated audio processing assembly corresponds to the target object.

Illustratively, the audio processing component is controlled to rotate by the motor control component, and the rotated audio processing component corresponds to the target part. The audio processing component captures audio from the target portion.
The motor control component converts a signal from the positioning component into a control signal of a stepping motor, taking the audio processing component as a loudspeaker as an example, the loudspeaker can be rotated slightly by taking the z direction as an axis through the stepping motor to control the audio direction of the loudspeaker to adjust and move in an x-y plane; alternatively, the speaker can be rotated slightly by the stepping motor in the y direction to control the audio direction of the speaker to adjust the movement in the x-z plane. Based on this adjustment, the audio direction of the speaker will be directed outward in various directions starting from the hole, and the final direction will be based on the target located by the positioning component.
According to the method and the device, the audio processing assembly of the terminal is dynamically adjusted based on the relevant information of the target object, so that the terminal can accurately output or collect audio, and the accurate audio output can reduce the interference to others; accurate audio acquisition can reduce the noise source by a wide margin, improves the recording quality.

The head position of the person is used to indicate the positional relationship between the head of the person and the terminal. For example, the head position of the person may be that the head is located on the upper side of the terminal.
In a possible implementation manner, the terminal determines a head area of a person from the outline of the person based on the outline and the head characteristics of the person; the terminal determines the position relation between the head and the terminal based on the position relation between the person and the terminal and the head area of the person.

And 606, controlling the audio processing assembly to rotate by the motor control assembly, wherein the rotated audio processing assembly faces to the head position of the character.
After the terminal determines the head position of the person, the terminal may determine rotation information corresponding to the audio processing component based on the current position of the audio processing component and the head position of the person, where the rotation information is used to indicate how the audio processing component rotates. Illustratively, the rotation information can be determined by the digital signal processing unit, and after the determination by the digital signal processing unit, the rotation information is sent to the motor control assembly; the motor control assembly controls the audio processing assembly to rotate based on the rotation information.
Step 607 is to determine an updated positional relationship between the person and the terminal, where the updated positional relationship is obtained by measuring the position between the person and the terminal again after the time when the related information is acquired.
In a possible implementation, after the audio processing component completes the rotation, the terminal performs the step of determining the updated positional relationship between the character and the terminal.
The updated positional relationship is a positional relationship between the person and the terminal obtained by the terminal remeasurement. In a possible implementation mode, sending millimeter wave signals through a positioning component, and receiving reflected millimeter wave signals reflected by people; and determining the updated position relationship between the person and the terminal based on the transmitted millimeter wave signal and the reflected millimeter wave signal.
At step 608, it is determined whether the updated positional relationship and the change between the positional relationships satisfy a preset condition. In response to the updated positional relationship and the change between the positional relationships satisfying the preset condition, execution is started again from step 602; in response to the update of the positional relationship and the change between the positional relationships not satisfying the preset condition, execution is started again from step 607.
In a possible implementation manner, after the terminal determines the correlation of the target object, the correlation is stored in the register, and after the terminal determines the updated position relationship, the updated position relationship is compared with the position relationship to determine the change between the updated position relationship and the position relationship. The terminal also stores the updated positional relationship in the register.

When the updated position relation and the change between the position relations meet the preset condition, the position of the character is obviously changed, the terminal needs to determine the head position of the character again, and then the steering of the audio processing component is adjusted.
In a possible implementation, in response to the change between the updated positional relationship and the positional relationship not satisfying the preset condition, execution is started again from the step of determining the updated positional relationship between the person and the terminal.

In a possible implementation, the target object includes a first object and a second object; a first one of the audio processing components corresponds to a first object; a second one of the audio processing components corresponds to the second object. A first one of the audio processing components serves a first object (i.e., the first audio processing component outputs audio for the first object or the first audio processing component captures audio from the first object) and a second one of the audio processing components serves a second object (the second audio processing component outputs audio for the second object or the second audio processing component captures audio from the second object). The first audio processing component and the second audio processing component are different components. In a possible implementation manner, the second audio processing component is all components except the first audio processing component in the audio processing component, or the second audio processing component is a part of components except the first audio processing component in the audio processing component. In one example, the number of first audio processing components and second audio processing components is the same; in another example, the number of the first audio processing components and the number of the second audio processing components are different, and the embodiment of the present application is not limited thereto.
In a possible implementation, a component closest to the first object among the audio processing components is determined as the first audio processing component; and determining a component closest to the second object in the audio processing components as a second audio processing component.
In a possible implementation, in case the target object comprises a plurality of objects, the default closest object to the terminal corresponds to the audio processing component. That is, in the case where the target object includes a plurality of objects, the default audio processing component serves the object closest to the terminal (i.e., the audio processing component outputs audio for the object closest to the terminal, or the audio processing component acquires audio from the object closest to the terminal).
