Abstract

The application provides a multi-loudspeaker assembly impedance dynamic adjusting circuit comprising a multi-loudspeaker assembly, a switch element assembly and a control unit; the multi-loudspeaker assembly comprises two or more loudspeakers with the same electroacoustic parameters; the switch element assembly comprises a plurality of switch elements, wherein switch levels of each switch element are respectively connected between the loudspeakers and power amplifiers and between anodes and cathodes of different loudspeakers; the control unit can connect or disconnect the switch elements according to set control logic; the switch elements are connected or disconnected so as to connect / disconnect the connected loudspeakers with / from power amplifiers, and series and parallel connection combinations between the loudspeakers can be controlled, thus adjusting the multi-loudspeaker assembly impedance. The adjusting circuit can dynamically adjust the multi-loudspeaker assembly load impedance, thus allowing the power amplifiers and sound units to work in the maximum performance as possible, and improving the expressive force of the maximum and minimum volumes.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a circuit for dynamically adjusting the impedance of a multi-speaker group. The present invention also relates to a sound. Background technique [0002] With the popularity of audio, people have higher and higher requirements for the sound quality of audio. [0003] Most of the current speakers contain multiple generating units, and each generating unit produces sound independently within its own range. Most of the speakers now use the method of parallel connection of the sounding units, that is to say, the input power of the sounding units in the same range in the sound system is the same, and the connection between the speakers is fixed, which is a constant impedance system. Each sound unit has an optimal power range. If the input power is too low or the input power is too high, the fidelity of the sound unit will be reduced. The same problem exists with the power amplif...
