Problems solved by technology

This connection and pairing method requires both the mobile phone and the Bluetooth device to be equipped with an NFC module. The high cost of the NFC module will undoubtedly increase the production cost and affect the popularity of this short-distance pairing application. Moreover, most of the existing mobile phones do not have an NFC module. It is even impossible to talk about close-range matching, which still needs to be solved technically

Embodiment Construction

[0017] Embodiment 1 of the present invention, smart phone bluetooth voice pairing method, its pairing steps are as follows: a, record audio frequency, can be any sound source, as birdsong, running water, singing etc., audio modulation is stored in smart phone, and modulation can adopt fixed Frequency modulation, delete the audio signal between the rising edge and the falling edge, such as image 3 is the acoustic waveform before modulation, Figure 4 In order to modulate the sound wave waveform, the implementation is also frequency conversion modulation. The audio signal between the rising edge and the falling edge is also deleted, and the start play button is established at the same time. You can play the audio through the start play button on the panel. The start play button is associated with Bluetooth start and synchronized start bluetooth;

[0018] b. Start playing the modulated audio, put the speaker of the mobile phone close to the voice receiver of the Bluetooth devic...

Abstract

The invention discloses a smart phone Bluetooth voice pairing method. The smart phone Bluetooth voice pairing method is characterized by comprising the following steps that firstly, audio is recorded, modulated and saved to a smart phone, a starting playing key is established and correlated with Bluetooth starting; secondly, the modulated audio is started, a voice receiver of a Bluetooth device is close to the modulated audio, recognizes the modulation mode and saves received modulated audio signals, and the Bluetooth device is started to enter a Bluetooth discovery mode; thirdly, phone Bluetooth carries out automatic pairing connection after discovering the Bluetooth device; fourthly, during pairing connection once more, the smart phone starts the modulated audio and gets close to the voice receiver of the Bluetooth device, and the voice receiver recognizes the modulation mode, compares and recognizes the modulation mode with the saved modulated audio signals and conducts automatic connection. According to the smart phone Bluetooth voice pairing method, the smart phone is used for running and playing the modulated audio, short-distance Bluetooth pairing connection can be achieved, the hardware cost is low, and safety, convenience and quickness are achieved.

Description

technical field [0001] The invention relates to a Bluetooth pairing method for smart phones and a device with voice recognition, in particular to a Bluetooth voice pairing method for smart phones and a sound box with voice recognition. Background technique [0002] With the development of smart phone technology, NFC short-range wireless communication technology has appeared on high-end mobile phones. This technology can be used to pair and connect with Bluetooth devices. The pairing is successful. For the first pairing, a pairing window will pop up, just enter the password, and then just touch it to automatically connect, which is safe, convenient and fast. Its working principle is that the NFC module of the Bluetooth device sends and reads NFC wireless signals intermittently. When the mobile phone turns on the NFC function and approaches the Bluetooth device, after a series of data exchanges, the Bluetooth device starts the Bluetooth module, and the background of the mobile...
