Abstract
An automatically controlled directional speaker includes a sound amplifying device, an image capture device, a computing device, an azimuth control motor and an amplitude control unit. The image capture device is provided for detecting the status of surrounding environment to generate image information, and the computing device is communicatively coupled to the image capture device for determining whether there is at least one face information in the image information, and the azimuth control motor is coupled to the sound amplifying device for controlling the azimuth of an output sound of the sound amplifying device according to the face information, and the amplitude control unit is communicatively coupled to the sound amplifying device for controlling the volume of the output sound of the sound amplifying device according to the face information. The speaker may be combined with a lamp to form an LED lamp with broadcasting and illumination functions.
