Abstract

The invention discloses a method and a device for adjusting an audio frequency and a sound apparatus. The method comprises the following steps of outwards projecting infrared light spots through a speckle projecting device; receiving reflected light rays, reflected back by the infrared light spots, through an infrared receiving device; determining the distribution information of surrounding obstacles according to the reflected light rays; adjusting the output characteristic of the audio frequency according to the distribution information of the obstacles. The method for adjusting the audio frequency, which is provided by an embodiment of the invention, by utilizing the speckle projecting device and the infrared receiving device, and by adopting the way that infrared rays are used as activebeacons to perceive an environment, is used for realizing the active detection and the self-adaptation adjustment on the environment. In comparison with existing detection ways of an ultrasonic wave,and the like, the realization cost of infrared detection is lower; moreover, the infrared detection is friendly to a surrounding environment; the undesirable influence cannot be generated to the surrounding environment (such as a pet, and the like), and the user experience is promoted.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to an audio adjustment method, device and audio equipment. Background technique [0002] With the development of smart home technology, various home appliances are becoming more and more intelligent, including smart audio equipment that can interact with users. Smart audio equipment can sense and detect the surrounding environment. When the surrounding environment changes, it will adjust the audio output characteristics, optimize the audio effect, and provide users with the best hearing experience. [0003] Existing smart audio equipment mainly perceives the surrounding environment through ultrasonic sensors. However, the cost of ultrasonic sensors is high, and ultrasonic waves have adverse effects on the surrounding environment, such as pets such as cats and dogs. Contents of the invention [0004] The main purpose of the present invention is to provide an audio adjustment m...
