In detail, the target-tracking speaker device 1 senses whether there is a target in the environment through the sensing module 10. For example, when the sensing module 10 senses that there are people in the environment, the processing module 12 controls the driving module 14 and the sound output module. 16 acts so that the sound output module 16 faces the position of the person in the environment, and elastically outputs suitable sound power to the person in the position and distance. This embodiment does not limit the form of the speaker device 1 that can track the target.

The sensing module 10 is used for sensing at least one target object at least one target position in the surrounding environment to generate a sensing signal s1. In practice, the sensing module 10 is, for example, an infrared sensor, an ultrasonic sensor, a heat sensor, a laser sensor or an image recognition sensor. This embodiment does not limit the shape of the sensing module 10 . In addition, the sensor module 10 is used to detect the orientation, distance and quantity of one, two or more targets located in the surrounding environment, and the targets are, for example, animals such as people, cats or dogs.

For example, the sensing module 10 is an infrared sensor, which is used to detect the body heat of the human body in the environment area to determine the position of the human body. The infrared sensor can absolutely detect the infrared radiation of the human body, so the sensing module 10 The temperature distribution of the surrounding environment, especially the position of the body temperature signal (that is, the user), can be controlled by infrared detection technology, thereby generating the sensing signal s1 to the processing module 12 .

In addition, the scanning range of the sensing module 10 is between 0 degrees and 360 degrees.
