Embodiment Construction

[0040] like figure 1 As shown, the speakers include a main speaker 30 , a left surround speaker 31 or a right surround speaker 32 . The speaker controls the drive system 20 to output power and current to drive the speaker to play sound.

[0041] In addition to the audio line 50, a communication line 40 is added between the computer 10 and the speaker control drive system 20 to connect with each other. The communication line 40 can be a UART line or a USB line.

[0042] like figure 2 As shown, the speaker control and driving system 20 includes: an audio circuit 50 , a communication circuit 40 , a pre-stage control 203 , a post-stage amplifier 204 , a control unit 201 and a power supply module 202 .

[0043] Wherein, the control unit 201 includes a single-chip microcomputer 2011 for controlling the front-stage control 203, the rear-stage amplifier 204, and the power module 202; an interface circuit 2012 connected to the computer 10 through the communication line 40; and An ...

Abstract

The invention provides a speaker control driving method and a system thereof, which is used for controlling the speaker working through a computer. The invention comprises: a voice band line, and a communication line; a front-end control connected with the computer through the voice band line; a back-end amplifier connected with the signal output end of the front-end control through the communication line; a control unit containing a chip microprocessor used for processing a relevant control signal, the control unit is connected with the computer through the communication line and establishes the communication link with a speaker control software arranged on the computer, using for commanding and controlling the coordination of front-end control and back-end amplification; and a power source module. The invention has the advantages in that: the system is convenient for a user to operate the speaker and improves the speaker service life, and controls the speaker to complete automatic power-up and automatic shutdown, thereby thoroughly solving the problems of strong noise on the speaker caused by computer power-up and shutdown.

Description

technical field [0001] The invention relates to a sound box control method and its system, in particular to a computer-based control and drive method for the sound box and its system. Background technique [0002] At present, the speakers on the market all adopt the traditional control method, that is, through various buttons and knobs on the speaker equipment, the power on and off of the speakers, volume, tone, and sound effect control and adjustment need to be directly operated by the user, which is very inconvenient; Speaker equipment is easy to wear and age due to its buttons and knobs, which will lead to poor contact, which will cause control failure and noise. This can seriously impair the speaker's lifespan. At the same time, when the user switches the computer on and off, if the speaker is not turned off first, it will also cause the speaker to generate strong impulse noise. Moreover, the speaker will consume a lot of power when it is working. If the user forgets t...
