Frequency divider of loudspeaker box

Abstract

The invention discloses a frequency divider of a loudspeaker box, which comprises an inductance coil L2, an inductance coil L1 provided with taps, capacitors C, and loudspeakers, wherein a circuit input end is connected with the first tap of the inductance coil L1; one pole of the capacitor C2 is connected with the left end head of the inductance coil L1; the other pole of the capacitor C2 is connected with the first loudspeakers; one pole of the capacitor C1 is connected with the second tap; the other pole of the capacitor C1 is connected with the second loudspeaker via the inductance coil L2; and an input end of the third loudspeaker is connected with the right end head of the inductance coil L1. According to the divider, signal input lines of the loudspeakers pass through the same inductance coil L, that is to say, the inductance coil L is reused for many times; during sound filtration, regardless of fractional frequency, input signals only pass through the single inductance coil L; all voltage of the inductance coil L is utilized almost without loss; a power signal has no loss; the distortion of sound is small; and recurrent sound quality is good.

Description

technical field [0001] The invention relates to the technical field of frequency dividers, in particular to a sound frequency divider. Background technique [0002] Speaker dividers can divide the sound signal into several frequency bands. For example, a two-way frequency divider is composed of a high-pass filter and a low-pass filter, and a three-way frequency divider adds a band-pass filter. Of course, it can also be made into a four-way frequency divider or a five-way frequency divider. The crossover is the "brain" in the speaker, which is very important to the quality of the sound. Existing speaker frequency dividers include a circuit (high-frequency frequency division circuit) connected to a tweeter, a circuit (intermediate frequency frequency division circuit) connected to a midrange speaker, and a circuit (low frequency frequency division circuit) connected to a woofer. In the circuit connected to the tweeter: let the current flow through the capacitor first, block ...

Problems solved by technology

That is to say, the more inductance is added to the frequency divider, the more power will be lost, the greater the loss of power signal, the more serious the loss of sound signal, the sound will be distorted and the reproduction quality will be worse.

In particular, the inductance L1 and capacitor C3 connected in parallel on the circuit not only waste power that should not be wasted, but also directly destroy its load impedance and resistance characteristics, making the sound even worse
