Abstract

The invention discloses a far field voice input device. The device includes a remote control and a host end module; the remote control includes an infrared signal microcontroller, buttons and an infrared light emitting diode; and host end module includes microphone arrays, two photodiodes, a microcontroller, two operational amplifiers and two baffle plates; two independent microphones are used forcollecting voice signals in real time; and the two photodiodes are used for receiving infrared rays emitted by the infrared signal microcontroller, and realizes the angle positioning from the remotecontrol to the host end module. Compared with the prior art, the infrared buttons can be adopted to arouse a voice identification function, and accurate arousing can be realized by fully utilizing existing remote controls. The angle positioning of a sound source can be realized through the adopted two photodiodes, the baffle plates and other mechanisms; the microphone arrays can be adjusted to bean azimuth solution during Beamforming according to the angle of the sound source, so that best noise elimination can be realized, and the accuracy of voice identification can be guaranteed; and the device is simpler in structure, and more convenient and flexible in operation and usage.

Description

technical field [0001] The invention relates to an intelligent voice input remote control device, in particular to a far-field voice input device, which belongs to the technical field of household appliance control. Background technique [0002] Traditional home appliances such as TVs, set-top boxes, DVDs, and air conditioners are all controlled by infrared remote controls. [0003] Chinese patent 201810085098.3 discloses a voice remote control method and device. The voice remote control method includes the following steps: connect the controlled device through a USB interface, obtain the control authority of the controlled device, receive voice commands, and control the controlled device according to the voice commands. In this way, the voice remote control of the controlled equipment is realized, the hands of the user are liberated, and the convenience of operation is improved. Utilizing the existing USB interface of the home appliance, the traditional infrared remote con...
