A method, device, circuit and remote controller for acoustic command recognition

Abstract

The present invention provides a sound wave command identification method and device, a circuit and a remote controller. The remote controller detects sound wave signals of a user through a sound detection circuit and output sound signals to a single chip microcomputer according to the wave sound signals, the single chip microcomputer converts sound signals to high-low level signals, identifies acorresponding sound wave command according to the high-low level signals and executes the sound wave command, and when the sound wave command is a command for searching a remote controller, a prompting circuit is controlled to emit prompting information and prompt the user about the position of the remote controller through the prompting information. The remote controller has a search function, when the user needs to search the remote controller, it is only needed to send out sound wave signals of the remote controller to control the remote controller to send the prompting information, the user can know the position where the remote controller is located according to the prompting information, and the whole searching process is simple and rapid; and moreover, the remote controller does notneed addition of a complex both-way communication or wireless transmit-receive function, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of sound wave recognition, in particular to a sound wave command recognition method, device, circuit and remote controller. Background technique [0002] In daily life, due to the random placement of some electronic devices, users often have the trouble of not being able to find them when they need to use them. For example, the remote controllers (TV remote controllers, air conditioner remote controllers, etc.) that people use more frequently are easy to be blocked by obstructions because of their small size. In addition, users place them more casually, so they can only rummaging through boxes and cabinets at home when they need to use them. Finding, which brings trouble to the daily life of the user, and if the complex two-way communication or radio transceiver function is realized on the remote control, it will increase the cost. Contents of the invention [0003] In view of this, the present invention ...
