CN2292360Y - Frequency-divider for loudspeaker housing - Google Patents

Abstract

The utility model relates to a frequency divider for a sound box. More than two strands of enameled wires are curled to form an inductor. The quality of sound which passes through electrical inductance waves to be reproduced is clear, and the rhythm is clear, which leads high sound and low sound not to be mutually disturbed, and leads the hierarchy to be clear.

Description

A kind of loudspeaker enclosure divider

The utility model relates to a kind of frequency divider of audio amplifier.

Inductance on the existing frequency divider all is by sub-thread enamelled wire coiled, its lower tone, and noise is many, and oscillography curve such as Fig. 4 are from scheming to show that frequency divider can not clearly show tone color.

The purpose of this utility model provides a kind of sound clarity, the frequency divider that filtering power is strong.

The utility model is made up of filter capacitor C1, C2, C3, C4 and inductance L 1, L2, it is characterized in that: inductance coil L1, L2 be respectively by the enamelled wire more than two strands elder generation coiled one, coiled coil then.

The utility model adopts such scheme, resets delivering to corresponding band after the music signal filtering respectively, and high and low sound is not disturbed mutually, and tone color is clear, penetrating, well arranged.

Fig. 1 is the utility model circuit theory diagrams;

Fig. 2 is the structural representation that bifilar enamelled wire is formed inductance L 1 or L2;

Fig. 3 is an oscillography curve chart of the present utility model;

Fig. 4 is the oscillography curve chart of existing coil.

Fig. 1, Fig. 2 are the structural representations of the schematic diagram of circuit of the present utility model and inductance L 1, L2.Described frequency divider is made up of filter capacitor C1, C2, C3, C4 and inductance L 1, L2.C1, a C2 termination L1 one end in parallel, another termination L2 one end, C3, a C4 termination L1 other end in parallel, another termination L2 other end, described inductance L 1, L2 by the elder generation of the enamelled wire more than two strands coiled one, coiled coil then.

As shown in Figure 3, Figure 4, the utility model is in test process, can produce music curve as shown in Figure 3, music signal is delivered to the loudspeaker unit of corresponding band after by frequency divider filtering respectively, make the music signal focus accurately, that analysis power is good, rhythm is bright and clear, sound reaches is clear, penetrating well arranged.
