Embodiment 1

[0033] Such as Figure 1-4 As shown, a speaker control system based on voiceprint recognition, the system includes speakers and data terminals arranged in multiple positions in the room;

[0034] The speakers include:

[0035] Voice signal collection module, used for collecting user's voice;

[0036] The voice storage module is used to filter out the background noise processing of the collected user voice, and the voice storage module will extract the processed voice signal information, and judge whether to store or perform an identity recognition operation;

[0037] The signal processing module is used to compare with the voice database stored in the memory so as to determine the identity of the user, and then complete the corresponding personalized music selection operation according to the identification result of the person;

[0038] The first wireless module is used for data transmission with the data terminal;

[0039] A power module, used to provide power to the enti...

Embodiment 2

[0046] This embodiment is further defined on the basis of the above embodiments, the first wireless module and the second wireless module adopt Bluetooth or WIFI transmission mode for data transmission, and use IEEE802.11a wireless protocol for WIFI transmission mode Communication; the voice storage module uses the characteristic sound collected for the first time as a distinguishing login name to establish a user account through the signal processing module, and simultaneously records the new user account's information on music image mode, sound mode, favorite song category, application preference and other usage habits data.

[0047] Other parts of this embodiment are the same as those of the foregoing embodiment, and will not be repeated here.

Embodiment 3

[0049]This embodiment is further defined on the basis of the above-mentioned embodiments. The voice signal acquisition module includes a filter unit and an A / D conversion unit; The signal is converted into a voltage signal. After the voltage signal is output from the voltage follower, connect the resistor R2, R2 is 20KΩ, and R2 is connected to the parallel capacitor C3 and resistor R3. The capacitor C3 is 10nF, the resistor R3 is 20kΩ, and the other end of the resistor R3 Two branches are connected, one of which is connected to the positive phase input of operational amplifier A, the other is connected in series with capacitor C2 and grounded, capacitor C1 is connected to the negative phase input, and capacitor C3 is also connected to the output of operational amplifier A. The positive bias voltage terminal of A is connected to two branches, one of which is connected to capacitor C3 and grounded, the other branch is connected to positive voltage, and the negative bias voltage t...

Abstract

The invention provides a sound box control system based on voiceprint recognition. The system comprises sound boxes arranged at a plurality of positions in a room and a data terminal, The sound box comprises a voice signal acquisition module, a signal processing module, a first wireless module, a power supply module and a loudspeaker module. The data terminal is a television or a computer and comprises a second wireless module and a man-machine interaction module. When music is played at home; a mobile phone does not need to be independently connected with an APP for music selection and playing; The loudspeaker box can automatically identify the voice information of the user, determine the identity of the user according to the voice of the user, and play music according to the previous music preference and music playing mode of the user, so that personalized film management is realized, the content is thousands of people and thousands of faces, the playing steps are reduced, and the preparation time before playing is greatly saved.

Description

technical field [0001] The invention belongs to the field of intelligent speakers, in particular to a speaker control system based on voiceprint recognition. Background technique [0002] At present, the way people play music through the speaker at home is mainly to connect the speaker with the bluetooth of the mobile phone, and then select and play music through the music APP on the mobile phone. But there are many problems in this process: (1) Every time you need to use your mobile phone to connect to the speaker via Bluetooth, and you need to select songs separately on the APP on the mobile phone, the operation is complicated and takes a long time; (2) When you are at home When other people want to listen to songs, they need to select and play songs on the mobile phone connected to the speaker, or choose to connect their mobile phone to the speaker, which also takes a long time and cannot reach the level of intelligence. Contents of the invention [0003] The purpose o...
